Abstract: ABSTRACT           An axial piston, variable displacement, wobble plate gas or vapor compressor containing improvements in the capacity control system and in the drive plate and wobble plate mounting arrangements.  A cam mechanism is driven by the drive shaft of the compressor, and at least one axially extending flange member is connected to the drive shaft.  A lug is associated with a cam mechanism having a portion in spaced, juxtaposed relation with a surface on the flange, and a pivot link is attached at one end thereof to the flange and at the other end thereof to the lug.  The lug is spaced from the axis of the drive shaft so that the cam mechanism is pivoted at a point not coincident with the drive shaft axis.  No drive connection is provided at the drive shaft axis between the cam mechanism and the drive shaft, the link being positioned between the flange and the lug means so that the torque is transmitted from the drive shaft to the cam mechanism without producing a substantial bending moment on the pivot link.

Abstract: ABSTRACT OF THE DISCLOSURE   A multi position actuator includes a plurality of pistons which are disposed within a cylinder and adapted to be moved predetermined distances in steps in response to predetermined pressures applied thereto.  One or more of a plurality of devices are selectively actuated to cause fluid pressure to be applied to move one or more of the pistons, dependent upon which ones of the devices are actuated.  An output element is driven in accordance with the pistons actuated.  In some applications, it is desirable to have an air or hydraulic cylinder extend in steps to specific positions in response to specific pressures.  Many pressure position actuators presently in operation use a delicate counterbalance to assure that they are maintained in set posi-tions after they have been moved to the desired positions.  Such counter-balance devices are often subject to variations in forces which cause their positions to vary.  One field in which it is desirable to maintain specific positions of a driven member is in connection with manual throttle operations used to control the speeds of vehicles, such as railway cars.  It is general-ly desirable to maintain certain selected throttle positions and speeds after the vehicle has started to move.

Abstract: ABSTRACT OF THE DISCLOSURE             A loopback testing system for an asynchronously operating fully duplex data transmission path comprising proximate and remote stations, a proximate-to-remote data transmission channel for transmitting data to the remote station at a relatively high maximum data transmission rate, and a remote-to-proximate data trans-mission channel for transmitting data to the proximate station at a relatively low maximum data transmission rate.  A test-waveform generator applies to the proximate station, for transmission along the proximate-to-remote channel, a test waveform presenting a data transmission rate at least approximately equal to the aforementioned higher maximum data transmission rate.  A loopback circuit at the remote station receives the thusly transmitted waveform and re-applies it at the remote station for transmission back to the proxi-mate station along the remote-to-proximate channel.  However, the loopback circuit includes a digital frequency divider which reduces the waveform-element transmission rate presented by the test wave-form to such a level that the waveform-element duration of the test waveform, as transmitted back to the proximate station, at least approximately corresponds to the aforementioned lower maximum data transmission rate.

Abstract: FILTRATION OF A COAL LIQUID SLURRY USING AN ETHYLENE VINYL ACETATE COPOLYMER AND AN ALCOHOL                 Abstract The rate of filtration of a coal liquid slurry is increased by adding an ethylene vinyl acetate copolymer and an alcohol containing 2 to 10 carbon atoms to the slurry prior to filtration or by adding the alcohol to the slurry and washing a precoat cake of filter aid with an oil solution of ethylene vinyl acetate copolymer prior to filtration. Although the ethylene vinyl acetate copolymer and the alcohol each provides a filter rate improving effect when used alone, a synergistic improvement in filtration rate is achieved by their combined use.

Abstract: A B S T R A C T         In a process for the treatment of fume-laden carbon monoxide evolved in carbothermic reduction of alumina the fume-laden gas is contacted with particulate carbon in a fluidised bed maintained at a temperature, preferably in the range 2010 - 2050°C and above that at which sticky aluminum oxycarbide forms. The temperature of the bed is most conveniently controlled by the rate at which fresh carbon feed material is added to the bed. The hot gas emerging from the bed is rapidly chilled to a temperature below the solidification point of aluminum oxycarbide. This is most conveniently achieved by contact with a large excess of cool alumina/carbon mix in a stream which is continuously circulated through a heat exchange state.

Abstract: METHOD AND APPARATUS FOR OPTIMIZING EDGE CUT OF BOARDS FROM CANTS AND THE LIKE                          Abstract of the Invention Cants from logs are conveyed transversely to their length to measure the cant thickness and position of the upper surface by passing under a thickness detector that directs the vertical positioning of a plurality of linearly spaced proximity edge sensors.  The cant passing a sensor causes a series of pulses related to the conveyor speed to be introduced into a computer to measure the width of the cant at each of the sensor positions.  The computer determines the alignment of the linear axis of the cant to yield the maximum board volume and directs the positioning of the cant relative to edging saws and transfer of the cant to a longitudinal conveyor for feed into the the edging saws. The apparatus employed comprises a frame supporting a conveyor having its travel transverse to the length of the cant to be transported and a plurality of upper and lower proximity edge sensors linearly spaced parallel to the length of the cant.  The upper sensors are adapted to be vertically positioned relative to the upper surface of the cant as established by a thickness detector positioned upstream of the edge sensors.  As the leading edge of the cant passes a sensor a series of electrical pulses is initiated to a computer for that sensor and as the trailing edge passes the sensor terminates the pulses, thereby establishing the cant width at each sensor position.  The computer determines maximum cant yield and directs positioning heads to position the cant in relation to edging saws for transfer to longitudinal conveyor for feeding into the edging saws.
