The station 23 comprises rollers 25, 26 which roll over the surface 54 of the lining material, a rake 27 for levelling the material, two lateral guide rollers 28, 29 adjacent the wall of the vessel, and two pneumatically-operated rams 31, 32. The ram carrier 23 is movable longitudinally through a guide 40. The guide is interconnected with the shute 21 via a telescopic rod 46. In another embodiment (Fig. 3, not shown), the ramming device includes a cross beam (60) for diametrically-opposite rollers 25 and a lifting unit in the form of a fixed piston and movable cylinder. The carrier member 36 is provided with means for pivoting the rams 31, 32 about a horizontal axis. As shown, piston and cylinder units 73, 74 are attached to wheel forks 70 supporting the roller 25. An arm 76, 77 pivotable about a bearing 75 is attached to the free end of the piston rod 74. Rams 31, 32 are mounted on arm 77, such that upon operation of the piston, the rams are pivoted about a horizontal axis in order to compact material not directly beneath the ramming station.

Filed: 1973-10-10
Abstract: 1429258 Semi-conductor switching circuits; CUTLER-HAMMER EUROPA Ltd 10 Oct 1973 [10 Oct 1972] 47379/73 Heading H3T [Also in Division H2] Semi-conductor switches Q1, Q2, Q3 continue to supply current to a load 10 after opening of the switch S for a time determined by a capacitor C3. When switch S is closed, Q5 and Q6 charge C3 to a voltage determined by Q7 and R14, R15. This holds off Q8 so that Q9, Q10 can energize a relay winding CR1 whose contact CR2 turns on the triac Q1 and the Darlington pair Q2, Q3. The load 10 now receives A.C. from L1 via D1 and D2, or else D.C. from L1 (if it is a D.C. source) via D1, the impedance of D1 being much lower than the Q2, Q3 path. When switch S is opened, Q6, Q7 go off and C3 discharges through R12 and P at a rate determined by P. After a time, Q8 conducts turning off Q9, Q10 and de-energizing the relay CR. Thus Q1, Q2, Q3, which carried the load current direct from the supply terminal L1 after opening of S, eventually turn off. While the relay is energized an L.E.D. is illuminated; while the timing operation is in progress it flashes on and off due to relaxation oscillation of a PUT Q11 with C5, the latter having been shorted out previously by Q12. Transient suppression components include a voltage sensitive register ZNR1, capacitors C1, C4 and resistor R4.

Title: Unloader valve
IPC: F16K17/10
Filed: 1964-12-07
Abstract: 1,079,030. Fluid-pressure servomotor systems. J. MERCIER and B. MERCIER. Dec.7, 1964 [Dec.18, 1963], No.49761/64. Heading G3P. [Also in Division F2] In an unloader valve for use between a pump 76 and an accumulator 80 to maintain the pressure in the latter between adjustable predetermined limits, fluid from the pump enters at 65 and flows to the accumulator via a check valve 69 and port 67. Fluid from the check valve chamber also flows, via a passage 68, to an annular chamber 46 defined by spaced annular flanges 28, 29 on a piston-like part 26 of a main valve member 25, from which chamber it flows, via a passage 47 to a pilot chamber 33 within the part 26. The outlet from chamber 33 comprises a valve seat 35 which is normally closed by a ball 45 acted upon by a spring 55 via a rod 52, but when the pressure in the chamber 33 reaches a predetermined level it moves the ball and repeats it against a second, larger, seat 42 surrounding an outlet passage 43 from the ball chamber 44. Fluid then flows via a passage 48 to a chamber 49 and acts on the end 51 of part 26 to move the main valve member 25 slowly to the right against spring 55 until it abuts stop 19, thereby moving a head 27 away from a seat 17 to allow the inlet 65 to communicate with a port 73 leading to the reservoir, the resulting drop in pressure in passage 64 allowing the check valve 69 to close. In moving to the right the main valve member further compresses the spring which increases the force tending to unseat the ball 45, but this is resisted by the pressure in chamber 44 acting over the larger effective area of the ball as determined by seat 42. When the pressure in the accumulator falls to a predetermined level the ball 45 is, urged by the spring to reseat against seat 35 thereby allowing fluid from chamber 49 to escape to the reservoir via passages 43, 72, which in turn allows the spring to close the main valve to complete the cycle. Adjustment of the maximum and minimum accumulator pressures is obtained by adjusting the nut 21 and sleeve 19 respectively. In the modification of Fig. 1a, the pilot ball 45 is replaced by two mushroom closure members 45a, 45b respectively integral with pistons 83a, 83b having channels 83c, 83d, which allow for rapid opening movement of the member 45a. The larger member 45b accommodates the increased force exerted by the spring when the main valve opens. In the embodiment of Fig. 5 the fluid in annular chamber 66' exerts a net force to the right on the main closure member to cause the latter to open against a spring 85 in the event that the pilot valve should fail to operate when the accumulator pressure reaches the predetermined maximum level. In this embodiment the ball 45' replaces the closure members of Fig. 1a but pistons 83a',  83b' are included.

Abstract: 1457196 Axial seals for Wankel engines AUDI NSU AUTO UNION AG and WANKEL GmbH 18 Nov 1974 [28 Nov 1973] 49899/74 Addition to 1362342 Heading F1F The annular seal assembly described and claimed in the parent Specification No. 1362342 is modified by cutting away the surface 5b or 6b of the L-sectioned scraper ring 5 or 6 remote from the respective C-sectioned resilient ring 13, 14, thus avoiding jamming of the axial limb 5a, 6a against the adjacent groove surface 3b, 4b. When not in use, the surface 5e of the axial limb of each L-sectioned scraper ring 5 is inclined relative to the axis of the ring, so that when the axial limb is, in use, deformed by the action of the resilient C-sectioned ring 13 thereon, this surface 5e is parallel to the ring axis and thus axial displacement of the C-sectioned ring is prevented.
Patent GB-1414972-A (GB)
Title: Method of conversion of shaft rotation angle into an electric  signal
IPC: G01D5/20
Filed: 1972-11-01
Abstract: 1414972 Measuring shaft rotation angles CHELYABINSKY POLITEKHNICHESKY INSTITUT IMENI LENINSKOGO KOMSOMOLA 1 Nov 1972 50413/72 Heading G1N The range over which a shaft rotation angle transducer operates linearly is extended by resetting the transducer each time it reaches the end of its linear range. When the transducer output reaches a predetermined value which corresponds to the end of the linear range it is reset (by adjusting its connections, for a sine-cosine transducer) to the other end of the range; this produces a change in the output level which is countered by generating a separate signal equal and opposite to this change. The final output representing the shaft rotation angle is thus the sum of the transducer output and the separately generated signal. In Fig. 3 the transducer is a rotary transformer 33, which has a linear output for angles in the range Œ#/3. Its windings are initially connected by a commutating switch 36 as shown by the dashed lines in the switch. The transformer is fed by power supply 35, and its output is taken from switch terminal 50. Suppose that the shaft is rotated from 0 to +#/3; when the latter value is reached the output at contact 50 becomes equal to a preset level, and this is detected by threshold device 58. This actuates logic device 59 to change the commutating switch 36 so that the transformer is reconnected and set to the -#/3 end of its range. This causes the output at 50 to change, which is countered by an equal and opposite signal generated at 39, also under control of the logic device 59. The output from 50, and the signal from 39, are summed at 38 to give a final output at 40. Rotation may now continue until +#/3 is again reached, in which case the procedure repeats. The device 39 is a transformer 62 having several secondary winding taps each giving an output equal to the change of output at 50 when resetting occurs; switch 61 selects the taps. The transformer 62 is fed by power supply 35, so that variations in the supply levels affect the transducer 33 and transformer 62 equally and are cancelled. In place of the electrical connection between the rotary transformer output 50 and threshold device 58, the latter may be actuated by any other transducer which supplies a signal when the shaft has rotated through a given angle. The various inter-connections set by commutator 36 as the shaft rotates are given in Tables 1 and 2 (not shown).
