Title: Improvements in or relating to hydraulic piston pumps and hydraulic transmissions
IPC: F01B1/06
Filed: 1961-12-08
Abstract: 973,036. Hydrostatic transmissions. ERNEST H. FISCHER'S SOHNE A.G. Dec. 8, 1961 [Dec. 12, 1960], No. 44064/61. Heading F2C. [Also in Division F1] A hydrostatic transmission comprises a pump rotor 1, Fig. 3, housing two banks of stepped pistons 6, 6<SP>1</SP>, and a motor rotor 1<SP>1</SP>, mounted on a common stationary valve member 3, the banks of pistons being controlled separately by angularly adjusting cam tracks 9, 10 and 10<SP>1</SP> and by varying the effective capacities of the pump cylinders. Axially adjacent pairs of pump cylinders are interconnected by ducts 14, and cam tracks 9 and 10 are movable relative to each other, by hand-wheels 13 and worms 12, so that when the cam tracks are in phase, the adjacent pistons move together and the effective capacity is a maximum, and when the cam tracks are 90 degrees out of phase, the pistons move in opposite directions and the effective capacity is nil. The cam tracks are rotated together relative to the valve 3 to vary the speed and reverse the direction of rotation. Cylinder portions 18 of each bank of cylinders are interconnected by an annular passage 19, Fig. 2, thereby forming a fixed volume closed circuit to provide a restoring force on the pistons. Prevention of concussion is provided by springs 22, Fig. 4, on the pistons.

Abstract: 1475004 Vapour disseminator PERMTEK INC 11 Oct 1974 [2 Nov 1973] 44260/74 Heading ASG A device from which the vapour of a volatile liquid is disseminated into the air comprises an outer casing 13 having an inner transverse wall 17 vented at 83 and 85. An inner container 35 is held in sealing engagement with wall 17, e.g. by spring loading and contains a volatile liquid contained within a sealed package permeable to the vapour thereof. The liquid may, for example, be dispersed on a spirally wound porous element 63 within the package which is supported so that air may circulate about it. Associated with the vents 83 and 85 is a circular shutter 91, rotatably mounted and movable by means of a grip 131 outside the casing, having openings 105 and 123 which may thus be moved in and out of registration with vents 83 and 85. At the same time, an electric motor 49 actuating an impeller fan 153 is switched on by means of a projection 99 on the shutter operating switch 241. This draws air through the container via the tube 111 and the outlet 85 into the passage 165 where it mixes with further air before leaving the device.

Abstract: 1358307 Remotely controlled switching systems PASS & SEYMOUR Inc 28 Sept 1971 [16 April 1971] 45090/71 Heading H2H [Also in Division H1] A system for remotely controlling the supply of power to a load 46 comprises a voltage source, a relay assembly 2 including a switch 30 for connecting and disconnecting the load from the source, a voltage pulse generator 1 located remote from the relay assembly and connecting leads for coupling the pulse generator to the relay assembly. The pulse generator 1 includes a switch having a manually movable arm 7 so that when the arm is moved to engage a contact 53, the arm movement also rotates a magnet 3 to induce a voltage in a coil 5. This voltage is supplied to the coil 8 of a reed relay having a switch 10 which is closed to supply the line voltage to the upper portion of a solenoid 16. The switch 30 is therefore closed to supply the line voltage to the load which may be a house light, a motor or a piece of machinery. Movement of the arm 7 to engage a contact 55 supplies the voltage pulse to the coil 12 to close the reed relay switch 14 thereby energizing the lower half of the solenoid 16 and opening the switch 30.

Seamless tubes are produced by passing a billet down skids 101, Fig. 1, into a rotary hearth furnace 102, turning it through 180 degrees in a device 103, transporting the block by a conveyer 104 to the table of a combined centring and sizing press (106), pushing it into a combined press-piercing and rolling mill 110 by a pusher 108, rolling it down a table 111 on to the rotating table 112 of a continuous roughing mill 113 and then on to the table 114 of a continuous finishing mill 115. After being rolled, the tube is freed by stripper plates 118, and cropped by a hot saw 119. If a large tube with thick walls is required, the tube is sized in a mill 120, after passing down on to a table 121. If a small tube is required it is produced by a stretch-reducing roll which is fed by a screw transfer device 122, a heat equalizing room 123, and pinch rolls 124. The mandrels 116 and 117 may be continuously cooled and lubricated internally, and the billet may be continuous cast. A roller conveyer 126 may be provided so that the heated billets can be supplied directly to roughing mill 113, so as to form wires. Press (106) comprises guides 128, 130, Figs. 4a-Ac (not shown), for the billet (127), and front and rear centre punches (136), (129), carried by rams (139) and (131) respectively. Billet (127) is aligned with guides (128) and (130), and is thrust through four rolls (135) forming a closed pass, by rams (131), (132), so that front and rear central holes are formed in the blank by punches (129) and (136). The continuous mill of Fig. 5 (not shown), may replace mills (113), (115), and comprises five pairs of rolls (201-205), each pair being turned through 90 degrees with respect to the adjacent pairs. The mandrel (206) has lubricant and coolant passages on the inside and outside of a tube (209), and poppet valves (210) allow the lubricant to flow into the space between the mandrel and the work (207), the lubricant burns to produce a high velocity stream of gas and the gas dislodges the scale formed on the workpiece.

Abstract: 1443945 Testing coins MARS Inc 8 Oct 1973 [12 Oct 1972] 47163/72 Heading G4V A method of testing coins comprises subjecting one side of a coin to an alternating magnetic field, detecting the field on the other side of the coin and comparing the phase of the field on the one side with the phase of the detected field on the other side. In the embodiment shown a transmitting inductor 320 is fed with a sinewave signal derived from oscillator 330 via a ¸256 frequency divider 332, amplifier 338 and pulse shaper 339. The transmitter and receiving inductors 320, 340 are connected via respective squaring circuits 371, 373; 372, 374 to the clock inputs of respective flip-flops 375, 377 the outputs of which are connected to the reset inputs of the other. The Q output of flip-flop 377 is therefore a pulse train of duty cycle proportional to the phase difference between the transmitted and recieved fields and is applied to one input of an AND gate 379. The other input to AND gate 379 receives clock pulses from a ¸11 divider 334 connected to oscillator 330, and its output therefore comprises groups of clock pulses the number of pulses in each group being dependent upon the phase difference. A predetermined number of pulse groups are applied to counter 380 via an AND gate 376, the second input of which receives a timing pulse from a further divider 336, and the content of counter is then compared with predetermined limits for an acceptable coin stored in memory 390. In a second embodiment (Fig. 7, not shown) the shaped signals from transmitter (720) and receiver (740) are applied to an exclusive OR gate (775), the output of which, having a duty cycle dependent on the phase difference, is integrated and compared with a set reference level. The receiving inductor (140) may be wound on a ferrite core (141) and positioned inside a conductive cylindrical shield (142) having a hole (144) adjacent the coin passageway (Fig. 2, not shown).
