Title: Improvements in or relating to temper mills
Inventor: SIMS RAYMOND BERNARD
IPC: B21B1/22
Filed: 1959-11-30
Abstract: 957,714. Automatic control of temper rolling mills. DAVY & UNITED ENGINEERING CO. Ltd. Nov. 23, 1960 [Nov. 20, 1959; Aug. 2, 1960], Nos. 40574/59 and 26714/60. Heading G3R. A control system for a temper rolling mill comprises means responsive to the rolling load to maintain the load at a substantially constant value. The mean rolling load is detected by strain gauge bridges 20, 21 of load cells 18, and, if the detected load differs from the value set by potentiometer 50, an error signal is applied to amplifier 51 to operate screw-down motor 17 and alter the setting of rolls 12. The load is thereby adjusted until the input to amplifier 51 is substantially zero and the load corresponds to the value set by potentiometer 50. The mill is also supplied with a device for detecting the proportional reduction effected on the strip by the rolls 12, comprising tachometers 32, 34, producing voltages representing the entry speed and the exit speed respectively. A motor 38 drives slider 37 until the voltage derived from potentiometer 36 is equal and opposite to the voltage on lines 33, the angular displacement of the motor representing the ratio between the speeds and therefore the elongation and reduction of the strip. The motor 38 also drives the slider 41a of potentiometer 41. If there is a long term drift in the reduction effected by the mill, there is a difference between the load error signal, applied to the amplifier 51, and the reduction error as detected by the difference between the signals on line 42 and from potentiometer 53. This difference in the error signals appears as an output on line 56 to alter the bias on amplifier 51 and restore the drift so that constant reduction is maintained. Minor irregularities in the output of the reduction detector do not affect the system because of the long response time of integrating circuit 55. The tension of the strip at the entry side is kept constant by a tension meter 60 controlling the speed of reel motor 25. Similarly, the exit tension meter 61 controls the speed of reel motor 26. The screwdown motor 17 may be replaced by hydraulic rams. Specification 952,074 is referred to.

Abstract: 1,012,041. Reciprocating motors; electromagnetic switches. MITSUBADENKISEISAKUSHO CO. Ltd. Nov. 17, 1961 [Nov. 19, 1960; Dec. 9, 1960; Dec. 12, 1960], No. 41177/61. Headings H2A and H2B. [Also in Divisions F1, F2 and H1] The armature 7 of an electromagnetically operable device is attracted and released by altering the reluctance of a magnetic circuit comprising a continuously excited coil 1 and a fixed core assembly 2, 3, 4 using a second pole piece 6 which is movable relative to the core assembly. Armature 7 may be slidably supported on non-magnetic tube 5 which encloses movable polepiece 6 and carries contacts 9 which co-operate with fixed contacts 11 for control of an external electric circuit. In a modification the control spring 8 is replaced by a plate spring which also carries the moving contacts 9. In a further modification the armature may be pivoted at one side. As shown in Fig. 6, the second polepiece 18 forms the armature of a plunger type electromagnet having an exciting coil 23 which is energized when contacts 28, 30 are closed. Plunger 18 is maintained in the position shown by spring 20 when coil 23 is de-energized so that armature 21 will be attracted when power is supplied to coil 24. When coil 24 is energized armature 21 is attracted to pole 26 against spring 29 and makes contacts 28, 30; coil 23 is energized and plunger 18 moves downwards against return spring 20 thus increasing the armature magnetic circuit reluctance and releasing the armature 21. Contacts 28, 30 open allowing plunger 18 to return to the position shown and the cycle repeats. In a reciprocating pump when plunger 18 moves upwards fluid is drawn into chamber 48 via spring controlled valve 43 from inlet port 55 through filter 49. On the downward stroke high pressure fluid passes through valve chamber 40 to outlet 42 and is expelled through outlet pipe 56 under pressure on the next upward movement of the plunger 18.

Title: Hose or Pipe Coupling
Inventor: WALTHER CARL KURT
IPC: F16L37/56
Filed: 1967-09-08
Abstract: 1,154,416. Pipe couplings. C. K. WALTHER [trading as CARL KURT WALTHER]. 8 Sept., 1967 [10 Sept., 1966], No. 41177/67. Heading F2G. [Also in Division H2] In a pipe or hose coupling, having at least one spigot 31, Fig. 1 and one socket 19 lockable in the coupled position by a locking member 15 displaceable by remotely controlled drive means, a driven member is connected through the locking member with one coupling part and a reaction member is connected to the other coupling part so that upon release of the locking member the drive member effects disengagement of the coupling parts. Spigots 31, 32 and (33), Fig. 3 (not shown) are secured to a carrier 28 which carries a plug 8 and the spigots are engaged in sockets 19, 20 which are secured to a carrier 16. The carriers 16, 28 also mount electrical spigot parts. Sockets 19, 20 are fitted with spring- closed valves 21, 22 and nipples 24, 26 are connected to the hoses or pipes (not shown). To disengage the coupling parts a magnetic valve 34 admits compressed air via admission port 36 aud axial passages 49 to the space above piston 5<SP>1</SP>. This causes the housing 1 to be displaced in the direction of arrow c relative to carrier 16, the movement also being imparted via bolts 7 and distance pieces 6 to the locking member 15 which moves to a position wherein the catch members 11 can be released from the circumferential groove in the plug 8. During completion of the displacement of housing 1 the piston rod 5 bears against the plug 8 and the housing 1 withdraws the sockets 19, 20. from spigots 31 and 32. In the event of pressure failure a handle 37, which is normally secured by a screw 39, is tilted to move plug 40 out of the engaged position shown in Fig. 1. This allows catch members 41 to move out of the groove in cover 2 to release a spring-loaded rod 3 which acts through piston 5<SP>1</SP> and piston-rod 5 on plug 8 to disengage the coupling. The handle 37 is anchored by a link to a fixed point and can rotate about the axis of plug 40 to adjust itself to the direction in which the force is transmitted through the link. In the event of failure of the release mechanism a predetermined external force causes a shear pin 13, securing a sleeve 12 to plug 8, to fracture thereby allowing the coupling halves to be separated by the external force. The coupling may be manually released by operation of a hand lever (47), Fig. 7 (not shown). The position of the housing 1 is indicated by a pointer (44), Fig. 6 (not shown).
