This was the first Mars lander designed after the bombshell from Mariner 4 that astronomers had drastically over-estimated how dense the Martian atmosphere was. They had figured it was a useful 85 hectopascals hPa , in reality it was an almost worthless 6 hPa just slightly better than a vacuum. By way of comparison Terra’s atmospheric pressure at sea level is hPa. The poor prior design that was rendered obsolete by the low atmospheric pressure was the Aeronutronic MEM The low atmospheric blow Mariner 4 dealt to the scientist was just the cherry on top of the sundae. Much more serious was the photographs. The scientists knew there could be no chance of images of scantily-clad Barsoomian princesses , but they were hopefull there would be some lakes and maybe even a canal or two.

A fibre rope reeved through a single sheave block. The beams are supported at each end by legs mounted on traveling end carriages. They have a crab with one or more hoisting units that are able to travel across the bridge beam or beams. Used where there is no supporting building for the crane. It can raise and lower a load and a limited amount of slewing can be achieved by adjusting the guys. GIRT A horizontal structural member in a wall of a steel structure which supports the wall cladding sheets.

Note, there should be a 3K pull up resistor on pin 1 and the feedback resistor should be K instead of 10K. Because what we are really meausring is the frequency of the oscillator, we can build a frequency meter using the same circuit at almost no additional cost.

Yes, I have trouble keeping track of the various problems, changes, and solutions to my devices over months of time. It’s funny how often I come here to see what I did about a particular problem. Nice way to keep a diary of this kind of thing. Notice also that the loop routine only calculates the power, updates the watchdog, and updates the alarm timer. If it hangs in a loop somewhere the watchdog will reset it and start over.

Every 5 seconds the alarm code causes it to send the data; that’s about as simple an implementation as I can come up with. The timers are set up in the setup routine and the reporting is done using the callback routine reportPower. The XBee for this device is set up in transparent mode; this is a specific mode for the XBees and you’ll understand this when you start working with the little devices, but it means that I don’t have to have special encoding or decoding software to use it. Device as of April 16, Three people now have asked me how to put the CTs in series.

It’s actually pretty simple to do: Then hook one color wire from one CT to the other color wire from the other CT.


The “T” is 4″ steel pipe. Steel discs with 1″ nuts were welded into each end of the “T” bar to accept the two 1″ hardened steel bolts which form the elevation axis. The axis pivots on 1″ flange bearings mounted on the side arms. This is a close-up of the attachment point of the elevation actuator to the circular mounting ring.

Gas[ edit ] Gases are compressible and change volume when placed under pressure, are heated or are cooled. A volume of gas under one set of pressure and temperature conditions is not equivalent to the same gas under different conditions. Liquid[ edit ] For liquids, various units are used depending upon the application and industry, but might include gallons U. Mechanical flow meters[ edit ] A positive displacement meter may be compared to a bucket and a stopwatch.

The stopwatch is started when the flow starts, and stopped when the bucket reaches its limit. The volume divided by the time gives the flow rate.

Hazards[ edit ] Ceilometers that use visible light can sometimes be fatal to birds, as the animals become disoriented by the light beams and suffer exhaustion and collisions with other birds and structures. Using optical instruments such as binoculars near ceilometers is not recommended, because lenses in instruments could concentrate the beam and damage one’s eyes. Optical drum ceilometer[ edit ] An optical drum ceilometer uses triangulation to determine the height of a spot of light projected onto the base of the cloud.

It consists essentially of a rotating projector, a detector, and a recorder. The projector emits an intense beam of light above into the sky at an angle that varies with the rotation.

These resistors are connected together with a coiled cord. A digital display is attached to one of the encapsulated resistor housings. Attach each encapsulated resistor to a hot stick of appropriate length for the voltages to be tested. Circuit Potential Testing — The digital high voltage meter can be used for measuring high voltage on cable. This includes phase to phase and phase to ground KV. Three modes of operation are available: Maximum value of voltage range is displayed.

High quality rugged extruded aluminum enclosure. Automatic shut-off activates after 10 mins of non-use Coiled, self-retracting cable is 16in retracted and 10ft when fully extended. Extended Voltage Ranges for Phasing Meters May be used on higher voltages with additional pairs of extension resistors. These extension resistors MUST be used in pairs to increase the voltage range.

The multiplying factors and ranges are as follows.


With four band transmission and eight band reception, this powerful radio delivers up to 40 watts UHF and 50 watts VHF for maximum range and power at extremely low cost! That’s only the beginning. The real power of the UV P is in its versatility.

Please keep in mind that most areas located below the height of a meter base is considered to be subject to physical damage. The only exception would be if a substantial structure is placed in front of the meter base.

If it’s the last thing I do! The world’s most famous crook! He is the captain of a crew of pirates aboard the Jolly Roger and the archenemy of Peter Pan. Captain Hook has long since abandoned sailing the high seas in favor of having revenge on Peter Pan for cutting off his left hand and feeding it to Tick-Tock considering it, by Mr.

Smee , a “childish prank”. While a worthy opponent for Peter Pan, Hook is destined to fail, sometimes because of Peter Pan’s ability to fly, but more often through the bumbling actions of his first mate, Mr.

Electrical cum hand operated For Compression test on Concrete or similar materials. Suitable for use on Concrete Cubes of any size upto 5cm x 5cm x 5cm, 7. The load is applied thru hydraulick assembly. The lower platen is on the Hydraulic ram, and upper having a spherical seating is adjustable. The machine is provided with an air release valve and the load is automatically indicated on the 15 cms diam hydraulic pressure calibrated against an N.

The switch is a five-inch device that is installed behind your electric meter by utility personnel. GenerLink eliminates the hassle of running multiple extension cords or the limited use of appliances.

A meter socket houses the electricity meter for your home and can also be known as a meter base. The meter itself is provided by your utility company and used to calculate your monthly bills. Individual states may have slightly different legislation about requirements for the meter socket but for the most part the installation is standard across the country. Step 1 – Check Regulations Although the regulations are relatively standard across the country you should check for any local exceptions or requirements before commencing work.

Some utility companies provide the meter socket as well as the actual meter so you should check that with them in advance so that you don’t buy extra equipment or carry out any unnecessary work. Step 2 — Assemble Components Assemble the meter loop piping and base socket, adhering to the regulations put in place by the supplying utility. The placement of this assembly must be correct and allow the utility company access when they require it.
