Abstract: ABSTRACT OF THE DISCLOSURE     A helicopter transmission mounting structure is disclosed in which at least three decoupled inertial isolators (26,38,30,32) are connected to the transmission (12) to support the helicopter fuselage.  Each of the inertial isolators (26,28,30,32) is mounted in the nodal plane of the transmission (12) to absorb inplane vibra-tions generated by a rotor blade and transmitted through a rotor mast (10).  The inertial isolators (26,28,30,32) respond individually to applied vibrations which have predetermined frequencies and generate counteracting forces to reduce the amplitude of vibrations transmitted to the fuselage.  In an alternative embodiment beam input links (134,136,138,140) are connected from the nodal plane of the transmission to inertial isolators (142,144,146,148).  The beam input links (134,136,138,140) are connected to transmit only those forces parallel to the rotor mast (10).

Abstract: ABSTRACT A vapor fraction containing hydrogen and at least one hydrocarbon selected from the group consisting of C1 to C4 hydrocarbons is separated from a hydrogen-rich refinery off-gas feed to give a liquid product fraction. The refinery off-gas is fed to and compressed in a com-pressor/expander having compressor means and expander means mounted and driven on a common shaft, and then cooled and partially condensed to form a two-phase fluid in a heat exchanger followed by separation of the vapor and liquid product phases of the fluid in a separator or a separator/fractionation column stabilizer unit. The separated vapor phase is transmitted to the compressor/ expander unit wherein the vapor is depressurized and partially condensed, thereby driving the compressor. The partially condensed depressurized vapor fraction from the expander and, optionally, the liquid phase product fraction from the separator are transmitted in separate streams to the heat exchanger for separate thermal contact with the compressed feed gas wherein the partially con-densed depressurized vapor fraction is fully vaporized and the feed gases are cooled. The fully vaporized fraction and the liquid product fraction are recovered in separate streams.

Abstract: ABSTRACT           The invention concerns apparatus and a method for detecting the presence of a coin in a coin passageway (14; 64/ 66 and 68).  The apparatus comprises a light source (25; 84) for directing a beam of light across the passageway at a first location and a light detector (26; 86) for detecting a beam of light crossing the passageway, at a second location, both located in one wall of the passageway.  A prism (29; 94) of transparent material is located in a wall of the passageway opposite the light source and light detector and has two 45° reflecting surfaces (32 and 33; 100 and 102).  The first reflecting surface (32; 100) reflects a beam of light from the light source (25; 84) towards the second reflecting surface (33; 102) and the second reflecting surface (33; 102) reflects the beam of light toward the light detector (26; 86).  Thus the beam of light from the source (25; 84) to the sensor (26; 86) crosses the passageway at two positions spaced from one another.  The method comprises the steps of directing a beam of light across a passageway in the intended path of a coin at a first location, reflecting the beam back across the passageway in the intended path of a coin at a second location and detecting the failure of the reflected beam to cross the passageway.

Abstract: ABSTRACT           A process and apparatus for washing fibre stock.  The fibre stock is passed along a passage 14 from a stock inlet 15 to a stock outlet 16.  The passage is defined by a portion of the inner surface of a substantially horizontal cylindrical screen 4, preferably a wire gauze.  Washing liquid such as water is introduced into the passage, preferably by means of apertures 9 in a longitudinally extending hollow member 8.   Effluent liquid passes through the screen, for extraction e.g. through outlets 24 and 25.   To enable the washing of stock of high consistency e.g. up to 8 %, whilst avoiding plugging of the screen 4, the arrangement is such that the stock only partially fills the cylindrical screen and is subjected to a tumbling action by the rotary movement of the cylindrical screen as the stock moves along the passage 14 to the stock outlet 16.   The hollow member 8 is displaced downwardly from the axis of the cylindrical screen, so as to be positioned within the tumbling stock.       In an alternative arrangement, the screen is defined by an endless belt carried over a series of rollers and having a portion of upwardly concave cross-section.

Abstract: RCA 75,068 ABSTRACT OF THE DISCLOSURE         A deflection generator periodically applies a trace voltage to a deflection winding to produce scanning current and periodically generates a retrace pulse voltage across the deflection winding.  A supply voltage source develops the trace voltage and also provides energy to circuits, such as a high voltage circuit, coupled to windings of a flyback transformer.  The high voltage circuit develops an ultor accelerating potential from the retrace pulse voltage developed across the high voltage winding of the flyback transformer.  A controllable switch such as an SCR is coupled to the source and to a secondary winding of the flyback transformer.  The trace voltage and energy transfer is regulated by controlling the conduction time of the SCR. The high voltage and other load circuits draw load current from the source through the flyback transformer secondary winding during retrace, resulting in high voltage retrace pulse duration and amplitude variation with variations in load current.  To maintain a constant raster width, the conduction time of the SCR is varied such that the trace voltage magnitude varies in the same sense as the retrace pulse voltage amplitude variations.
