Title: Reversible vane fluid power device such as a pump or motor
IPC: F04C2/344
Filed: 1960-12-29
Abstract: 897,875. Reversible vane pumps or motors. BENDIX CORPORATION. Dec. 29, 1960 [Jan. 8, 1960], No. 44643/60. Class 110 (2). A reversible vane pump or motor comprises a frame 20, housing 24 and end-piece 25. The rotor 28 inside the housing has radial slots 30 in the periphery in which slide vanes 36, slightly narrower than the slots, to permit the vanes to pivot slightly about an axis parallel to the axis of the rotor. Each wall of every slot has a transverse groove 72 or 72a just below the outer corner 70, and radial passages 74 or 74a extending from the transverse groove to the bottom of the slot. With high pressure fluid on the left of the vane in Fig. 3, the vane takes up the position indicated by 36 and high pressure fluid flows into groove 72a, down passages 74a to the bottom of the slot 30, and assists spring 34 in forcing the vane against the confining surface 26. When high pressure fluid is on the right of the vane in Fig. 3, fluid flows into the bottom of the slot through groove 72 and passages 74, the vane having taken up the position indicated by 36a. Fluid cannot pass from the high pressure side to the low pressure side since passages 74, 74a do not extend to the top of the slot. Convexities 40 at the bottom of each slot are connected by annular groove 45 so that since the total quantity of fluid at the bottom of all the slots is roughly, constant, very little fluid has to flow through grooves 72 and passages 74. Inlet and outlet passages 44, 46 communicate by means of annular grooves 48, 56, respectively, ports 50, 58, respectively in the rotor, and passages 52, 60, respectively to the periphery of the rotor adjacent to the vanes. Each port 50, 58, is connected to a balancing port respectively on the opposite side of the rotor. The rotor and the rotor shaft 22 are connected by spindle 32 having a crowned spline portion 33 at each end, thus providing a universal type joint. Leakage of fluid may be tapped-off through outlets 69 and 66.

Title: Automatic thickness regulating device for skin-shaving machines
IPC: C14B1/10
Filed: 1972-09-28
Abstract: 1355469 Shaving skins LUIGI RIZZI & C SpA 28 Sept 1972 [15 Dec 1971] 44724/72 Heading C6C In a machine in which a skin to be shaved is passed between a rotary shaving drum 2 and a pressure roller 1, an automatic thickness regulator reduces the spacing between roller and drum during the initial part of a shaving operation so that a skin is trimmed to a lesser thickness over its trunk region than at its end, e.g. its hind region, at which shaving is commenced. The roller 1, carried by a bracket 4 pivotally mounted at 5, is engaged by a motor-driven roller 14, whilst the drum 2, which has blades 3 arranged in left and right hand helices and is carried by a frame 18 pivotally mounted at 19, is driven at high speed by means (not shown). To open the machine for starting, a rotary valve 12 is turned to cause upward movement of a piston 9 which, through a rack and pinion 8, operates an eccentric to turn the bracket 4 clockwise about its pivot 5. Reduction of pressure in the chamber above the piston 9 is communicated through a pipe 44 to the lower end of a tapered slider 42 which, due to a connection 45 to a pressure oil supply 11, is depressed so that it moves a feeler 40 and valve member 29 to the right, thereby allowing oil under pressure to pass from a connection 24 to a pipe 26 so that a piston 21 is depressed to pivot the frame 18 anti-clockwise about its pivot 19. The slider housing 43 is carried by the frame 18 so that the movement of the latter returns the valve member 29 to neutral. The degree of separation of the drum and roller is determined by a stop screw 48 which limits the downward movement of the slider. When a skin has been inserted between the drum and roller, the valve 12 is returned to the position shown so that the piston 9 is depressed to move the roller back towards the drum, and pressure is re-established in the pipe 44 and below the slider so that the latter is restored at a controlled rate, determined by a restriction 46, to its upper position, the valve member 29 thereby admitting pressure oil to a pipe 27 to move the piston 21 upwardly and return the frame 18 and drum to a position for shaving the trunk region of the skin. This position is determined by a lever 39 having a screw-threaded connection with a sleeve 28 surrounding the valve member 29. The lever 39 may also be used to increase the shaved thickness of the skin towards the end of a shaving operation, e.g. at the head and neck end.

Title: Duplexer
IPC: G01S7/03
Filed: 1969-09-22
Abstract: 1291127 Waveguide duplexers RCA CORPORATION 22 Sept 1969 [30 Sept 1968] 46469/69 Heading H1W A duplexer comprises two parallel waveguide paths 17, 19 coupled at either end by quadrature hybrid couplers 13, 15 to afford four ports 41, 42, 43, 44, the paths each containing a non-reciprocal 180 degree phase shifter, one of the phase-shifters being reversible. As described (Fig. 1, not shown), the phase shifters are of the type using elongated, axial elements of square-loop ferrite which can be switched to a desired condition of remanence by a current pulse passed through an axial conductor. They are non-reciprocal in the sense that waves passing in one direction suffer 180 degrees more phase-shift than waves passing in the other. In the transmitting mode (Fig. 3), the phaseshifters are both set to delay waves passing from R to L by 180 degrees and to have no effect on waves passing from L to R. Taking into account the inherent 90 degree phase-shift of the hybrids 13, 15, it can be seen that the equal portions of energy travelling via the two paths from transmitter (port 41) to antenna (port 44) arrive in phase, and those travelling from transmitter to dummy load (port 43) arrive in antiphase. Further, it can be seen that energy reflected from the antenna port is coupled entirely to the transmitter port. The effects are independent of temperature. In the receiving mode (Fig. 4, not shown), the non-reciprocal phase shifter in path 19 is reversed and provides a phase delay of 180 degrees for waves travelling from L to R. Energy from the antenna port 44 is coupled entirely to the receiver port 42. If the transmitter operates by accident, all the power is applied to the dummy load port 43 and reflections from thence are coupled back entirely to the transmitter. The hybrid couplings shown are of the short-slot type.
