Title: Improvements in or relating to valves for the control of fluids
IPC: F16K1/46
Filed: 1957-11-06
Abstract: 842,228. Valves. PALEN, P. H. Nov. 6, 1957, No. 34649/57. Class 135. A valve comprises a resilient ring 3, Fig. 1, mounted on a supporting member 4 and situated between a fixed seat 7a formed by the intersection of a counterbore 15 with an annular, plane surface formed at the bottom of an enlarged bore 13 and a movable member 2 having a counterbored portion 14 providing a seating 5a of the same diameter as that of the seating 7a. The diameter of the seatings 5a, 7a is equal to the mean diameter of the ring 3 which is initially of circular cross-section or, alternatively, of a cross-section of C, D or U form. Excessive compression of the sealing- ring is prevented by slotted extensions 4b of the support-member 4. The support-member 4 is mounted loosely between the fixed and movable members of the valve so that when the member 2 is lifted by means of a stem 9 passing through a gland 10 the fluid flowing from the inlet 13 to the outlet 12 may pass on either side of the ring 3 depending upon whether the latter has remained on the seating 7a or has moved upwardly with the member 2. The stem 9 may be provided with a spring to compress the ring 3 when the valve is closed. For flow in the opposite direction a supporting member 4 is provided on the outside of the ring 3 and in the case where flow in both directions is possible support members both inside and outside of the ring 3 may be provided. Fig. 3 shows a valve consisting of movable members 17, 31 attached to a part 18 and coacting with resilient sealing-rings 24, 25 for connecting an outlet 20 alternatively with an inlet 19 or a vent 21. The sealing-ring 24 has an inner supporting-member 35, as in Fig. 1, to support it against the radially inward flow of fluid whilst the sealing-ring 25 has an external supporting member 36 to retain it against the radially outward flow of fluid. By making the seating edges of the movable members and of the valve housing of equal diameter and equal to the diameter of the parts of the members 17, 31 that are fitted with sealing-rings 32, 33 and slide in bores in the valve housing, the valve assembly is arranged to be balanced as regards the fluid pressures acting upon it. In another embodiment the movable member 56, Fig. 6, urged towards closure by a spring 86, is adapted to be moved to open the valve by a solenoid 52. The member 56 is arranged to be balanced as regards the pressure at the inlet 60 by the provision of a passage 73 leading to an annular chamber 57 and as regards the pressure in the outlet 61 by the formation of a counterbore 85 of diameter equal to that of the seating portions 86, 70. The bore 85 is sealed from the chamber 57 by a plug 75 with sealing-rings 74, 78.

Patent GB-892637-A (GB)
Title: Improvements in or relating to decimal digit indicators
IPC: G11C19/00
Filed: 1958-10-31
Abstract: 892,637. Electronic counting apparatus. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct. 31, 1958 [Nov. 4, 1957], No. 35028/58. Class 106 (1). An electrical digit indicator is provided with a counting circuit having five output terminals each connected to two indicating members, the counting circuit stepping first in one direction and then in the opposite direction upon operation of a changeover switch which also determines which of the two indicating members are operated at each counting stage. In the indicating arrangement shown in Fig. 1, the counter 15 is arranged to apply an operative voltage in sequence to terminals 10-14 in the forward and then the reverse order in response to pulses at input terminal 16. The counter remains twice at the extreme terminals, thus providing a complete cycle of ten steps. A pulse is applied to output terminal 17 at each extreme position, and to output terminal 18 when the counter is at terminal 10; i.e. output pulses are obtained after every fifth and every tenth input respectively. The pulses at 17 switch over a change-over switch comprising a bi-stable trigger circuit A and a pair of gates P 1 , P 2 . This causes indicating members, e.g. lamps, 0-4 to be operated for the forward sequence and members 5-9 for the reverse sequence. The decimal digit indicated can be replaced by its "9's" complement by applying a pulse to terminal 19. The counter may comprise trigger circuits B 1 -B 3 , Fig. 2, cascade connected through delay elements V 1 , V 2 , each input pulse i, Fig. 3, at 16 being followed by a pulse i<SP>1</SP>, e.g. derived therefrom, applied at 20 to gates G 1 , G 2 . The states of the circuits are sensed by gates A 0 -A 4  associated with the terminals 10-14. During the forward sequence, the input pulses are applied to B 1  only. After the counter reaches the position corresponding to " 4," gate G 1  is opened so that the next pulse i<SP>1</SP> restores the counter to the " 4 "-representing state (see Fig. 3) and switches over trigger circuit B 4  (corresponding to A, Fig. 1 so as to open gate G 3 . The input pulses i are then applied to all three stages B 1 -B 3  so as to cause the counter to step through the reverse sequence. After the counter reaches position " 0," gate G 2  is opened to the next pulse i<SP>1</SP> which again restores the counter to its previous position, switches over B 4  and also supplies a pulse to terminal 18. Reference is made to subtraction by complementing the minuend and then the result.

Filed: 1969-07-15
Abstract: 1,270,981. Rolling mills. MANNESMANNMEER A.G. 15 July, 1969 [16 July, 1968], No. 35456/69. Heading B3M. A pilgrim mill includes a main motor 1 which both reciprocates a roll stand 3, and drives feeding and indexing mechanisms for a workpiece through gear-boxes 5, 6 and 9. Two output shafts 12 and 13 are driven from the gear-box 9, the shafts being in threaded engagement with reversible feeding slides 10 and 11. The gear-box 5 drives a chuck 8 for a workpiece, while the gear-box 6 changes the rotation of an input shaft 4 into adjustable rotation and reciprocation of an output shaft 31, Fig. 6. The gear-box 9 transmits the motion of the shaft 31 to the output shafts 12 and 13 driving the feeding slides 12 and 13, and incorporates a reversing mechanism for the output shafts. Rotation of input shaft 4, Fig. 6, is transmitted through gears 28 to 21 to the shaft 31, the gears 25 and 26 being interchangeable to vary the transmission ratio of the gear-box. The shaft 4 also rotates a cam 16 which pivots a follower arm 17 about a bearing 18 to reciprocate a shaft 20 and hence the shaft 31. Movement of the bearing 18 permits the stroke of the shaft 31 to be varied. The rotating and reciprocating movement of the shaft 31, Fig. 5, is transmitted through a common worm shaft to worm gears 32 and 33. These gears rotate similar gears 36, 37 through one or other of two clutches 34, 35. The gears 36, 37 are of opposite hand and are coupled by a common worm shaft, such that when one clutch is disengaged, the gears rotate in one sense, and when the other clutch is disengaged they rotate in the opposite sense. Output shafts 12 and 13 driven by the gears therefore cause movement of the slides 10 and 11 towards or away from each other. The operation of the clutches is hydraulic and is controlled by the slides reaching their end positions.
