Abstract: ABSTRACT OF THE DISCLOSURE              The source support 3, 8 is mounted relative to the base 16 by means of spring elements 15. It comprises a support member 8 and a bearing plate 3 with the bearing surface, a bearing pocket 4 and a choke bore 5. The support member 8 and the bearing plate 3 are movable relatively to each other in the supporting direction and together define a pressure chamber 7 through which the load-bearing pressure fluid is passed to the choke bore 5. A spring 12 is provided which pulls the bearing plate 3 and the support member 8 towards each other counter to the force produced by the pressure chamber 7.          The displacement distance between the bearing plate 3 and the support member 8 is greater than the displacement distance between the support member 8 and the base 16.           In this way, the bearing plate 3 is resiliently pressed against the machine part to be supported, in operation, but if the supply of pressure fluid fails it is pulled away from the machine part so that no wear can occur.

Abstract: Oil Return System and Method Abstract A refrigeration system including an oil return system for a refrigerant compressor for returning oil accumulated within a first portion of the compressor operating at refrigerant discharge pressure to a second portion of the compressor operating at substantially suction pressure.  The oil return system includes a first conduit connecting the first portion of the compressor with the second portion thereof, for delivering lubricating oil accumulated within the first portion to the second portion.  A normally closed valve is interposed in the conduit for controlling flow of lubricating oil through the conduit.  The magnitude of the pressure in the second portion of the compressor is monitored, with the normally closed valve being opened when the sensed pressure decreases below a predetermined level for enabling the oil to flow through the conduit from the first portion to the second portion.

Abstract: ABSTRACT   A rowing machine has a frame, a handle pivoted to the frame for fore and aft movement, a seat which is slidable along the frame, and an energy-dissipating mechanism which acts between the handle and the front part of the frame, by means of a webbing strap extending between these parts, to resist rearwards movement of the handle.  To make the machine more compact for storage purposes, the frame comprises two portions which are hinged together, and can be folded together for storage purposes.  In the folded position, the handle hooks under the seat, to keep the machine in this position.

Abstract: ABSTRACT OF THE DISCLOSURE         An adjustable pitch drum consists of a drum shell having an open end, a drum head pitch changing mechanism, and a supporting structure mounting the pitch changing mechanism to the drum shell.  The pitch changing mechanism consists of a threaded rod adjustably threaded to the supporting structure, a drum head clamping hoop mounted coaxially on the rod for rotation thereabout, and a drum head tensioning hoop non-rotatably mounted on the other end of the rod.  Rotation of the drum head and its clamping hoop about the rod varies the tension of the drum head on the tensioning hoop, thereby changing the pitch of the drum.  Movement of the threaded rod in the supporting structure changes the spacing of the drum head from the drum shell open end, thereby changing the resonance characteristics of the drum assembly.  The supporting structure comprises a rigid multi-legged spider, preferably having legs of adjustable length, which supports said rod and has said legs shaped to fit over the peripheral edge of a drum shell and be held in place by a drum hoop.

Abstract: Multi-Axis Force Stick, Self-Trimmed Aircraft Flight Control System Abstract A four axis force stick provides signals indi-cative of force applied to the stick in an axis corresponding to a control axis of an aircraft, including pitch, roll, yaw and lift/speed.  The force-related signals are applied through propor-tional and integral gain signal paths to operate electrohydraulic servos that control the aerodynamic surfaces of the aircraft, such as the cyclic and col-lective blade pitch of the main rotor and the tail rotor blade pitch of a helicopter, or the ailerons, rudder, elevator and thrust of a fixed wing aircraft. Signal conditioning provides a dead band to avoid integrating minute, inadvertent force stick signal outputs, and vernier sensitivity at low forces with high gain at high forces. Analog and digital embodi-ments are discussed.  The relationship between this wholly new mode of aircraft control and ancillary aircraft functions, such as ground steering, autopilot and stability functions, are also discussed.

Abstract: Abstract of the Disclosure A universal light integrator/timer is provided for use with photographic equipment wherein several desired exposure intervals for each of a plurality of light sources may be preset and stored in a microprocessor for instant selection by the operator during a photographic operation.         When a stable light source is used the system is arranged to function as a timer and counts pulses derived from the AC line to control the light source in accordance with the preset exposure intervals.         When a light source is used whose wavelength and intensity varies during warmup, the system is arranged to function as a light integrator.  To obtain light integration the current flowing in a photodiode, which is linear with respect to light output, is amplified and converted to variable frequency pulses which are counted by the micro-processor to control the light source in accordance with the present exposure intervals.

Abstract: ABSTRACT A device for testing printed-circuit boards is described.  A problem with one type of known testing device is that it can only be used for testing identical or nearly identical printed circuit boards because the arrangement of contact pins engaging the printed circuit board conductors and providing the signals to the measuring device or meter is fixed.  In another case there is some facility for adapting to different printed circuit boards but this involves the individual masking with foil of certain ones of the pins.  Accor-ding to the present invention a base member contains a master grid of socket connectors which are hard-wired to the meter.  A pin carrier board supports the contact pins and an intermediate board is provided between the carrier board and the base member.  The intermediate board has contact pads on its upper surface which contact the pins and has plug connectors joined to these contact pads and projecting below the board for reception in the sockets of the base member.  The intermediate board has a contact pad pattern corresponding to that of the printed circuit board and the intermediate board is replaced with an appropriate one every time the type of printed circuit board is changed. Alternatively or additionally, the pin pattern may also be changed as the printed circuit board is changed.

Abstract: ABSTRACT OF THE DISCLOSURE            In a method for hydrogenated coal liquefaction, using rubbing oils and hydrogen-containing circulation gas, the non-liquefied solid components are concentrated in a hot separator subsequent to the liquefaction reactor, under similar tempera-ture and pressure conditions as in the reactor.  Gaseous and vaporous discharge products from the reactor are condensed in subsequent stages.  Non-gaseous and non-vaporous separation products, extensively freed of distillable oils, are removed from the hot separator in still pumpable condition, and relaxed in a subsequent fume extractor.  The hydrogen-containing cir-culation gas is conducted through the hot separator in contact with the discharge products from the liquefaction reactor, in an amount greater than 5,000m3, given at standard temperature and pressure per ton of water- and ash-free charge of coal.          Variations include branching off part of the circulation gas before the liquefaction reactor and conducting it directly into the hot separator, preheating this branched-off  part of the circulation gas before introduction into the hot separa-tor to temperatures between 300° and 550°C, and recovering rubbing oil in an intermediate separation stage directly following the hot separator.
