Abstract: A trash compactor system which includes a trash compactor unit, a compaction receptacle and a trash deposit door disposed above the receptacle to enable trash to be desposited in the system. The door is automatically opened when a person approaches the compactor to deposit waste material therein by pressure being applied to a mat switch positioned on the floor adjacent the compactor. The compactor member compacts waste in the receptacle by passing through a compaction cycle. When pressure is removed from the switch, a predetermined time period has elapsed and the waste deposit door is closed, the compaction cycle is initiated. At this time, mechanical locks within the compactor are forced against the door, preventing the door from being opened during the compaction cycle. The mechanical locks are released after the compaction cycle is completed.

Abstract: A method and apparatus for simulating the manner in which a ribbon of known profile is wrapped around a carcass of known profile in accordance with a predetermined winding specification is disclosed. The profile of the ribbon, the profile of the carcass and the winding specification are stored in a memory together with the desired final profile of the ribbon build. The profile of the final ribbon build, which will be created at a selected cross-section of the carcass when the ribbon is wrapped around the carcass in accordance with the winding specification, is calculated. The final ribbon build so calculated is displayed on a video display which also displays the desired final profile so that the profile created by the predetermined winding specification can be compared to the actual profile which will be produced by the winding specification.

Abstract: The invention relates to nondestructive inspection apparatus for automatically inspecting the end region of a tubular member and a coupling member secured to that end region. An inspection probe is yieldingly received within a housing that is pivotally supported on an arm that moves helically around the tubular member. The probe is extended outwardly from an air chamber in the housing to contact the surface of the tubular member. When the probe encounters the obstructing shoulder of the coupling on the end of the tubular member, the housing is caused to pivot to activate an air escape mechanism to reduce the air pressure in the chamber and cause the probe to be withdrawn radially to hop over the obstructing shoulder on the coupling. The housing then returns to its original position to terminate the air escape from the chamber. Air pressure builds up again to force the probe outwardly onto the surface of the coupling.

Abstract: A telemetry system adapter for connecting a recording station to a telemetry system having a plurality of data acquisition array terminals serially connected together by cables. The adapter may be used to connect the recording station to any array terminal in the telemetry system. At the array terminal to which it is desired to connect the recording station, the cable is disconnected from the array terminal and connected to one connector of the adapter. Another connector of the adapter is connected to the array terminal, and a third connector of the adapter is connected to the recording station. The connectors on the adapter will fit only a respective one of the array terminal connectors, the cable connector or the recording station connector, and therefore cannot be attached incorrectly. The adapter may include an attenuator for balancing data levels and reducing cross-talk interference.

Abstract: The system comprises stationary and removable couplers. The stationary one is mounted in a pipe flange by a thread ending in a stop flange. The stationary coupler is adapted to alternately receive each of a pair of removable couplers, one being adapted to receive the female end fitting of a hose, and the other the male end fitting of a hose.

Abstract: A modular telemetry cable system having first and second array terminals spaced apart a distance of D. A cable extends between the terminals having X number of analog signal transmission means which is connected to 2X transducer sets for gathering 2X analog signals. The analog signals are processed and transmitted as digital signals over a digital transmission means connected between the terminals. At the location in the cable of the two interior transducer sets, the cable is penetrated to connect the interior transducer sets to the same analog transmission means. The portion of the same analog transmissions means between the two interior sets is disconnected from the two interior sets. At the penetrations in the cable of the two interior sets, the other analog transmission means are cut. One transducer set on opposite sides of the cuts in the other transmission means are connected to each of the other analog transmission means.

Abstract: A relay adapted to be mounted on a printed circuit board, and a method for mounting such relays. The relay includes the usual terminals (23, 24, 26 27, 28, 29) extending therefrom and adapted to be mounted on a printed circuit board (30) and electrically coupled to conducting paths on the board. In addition, however, the relay is provided with additional load terminals (56, 59, 62, 82, 92) which function as external connection junctions to connect the relay directly to the load being controlled via a circuit that completely bypasses the printed circuit board. According to a preferred embodiment, the relay includes stationary contact members formed to have not only board-mounted terminal portions extending therefrom but also external terminal portions for direct attachment to the load.

Abstract: The invention is a method and apparatus for substantially eliminating from a seismic signal channel an interfering hiline signal in a differential mode. Differential mode and common mode components of the interfering signal are coupled from the seismic signal channel, and are correlated with each other to obtain a correlation signal. The correlation signal and the common mode signal are multiplied to obtain a correction signal that is applied to the seismic signal channel to substantially eliminate the differential mode component of the hiline interference signal. The correlation between the differential mode and common mode signals is accomplished with both in-phase and quadrature phase components of one of them so that two correlation signals actually are produced.

In which case, the belt is driven with the same speed as the weighing conveyor belt, via a terminal roller and the other rollers follow.
