Title: Improvements relating to clamps for supporting cables
IPC: H02G7/05
Filed: 1934-05-10
Abstract: 438,200. Suspending cables. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, Westminster, and POOLE, W. E., 45, Cromwell Road, Beckenham, Kent. May 10, 1934, No. 14092. [Class 36] In a suspension clamp of the kind in which the clamping pressure is derived from the weight of the cable supported by the clamp, the cable is clamped by a sleeve SL which is split in a vertical plane into two parts, the two parts being hinged on a pin PI arranged below the longitudinal axis of the sleeve. The sleeve is formed with trunnions TU, TR which rest on supports PO, PR projecting inwardly towards each other from recesses RS, RC formed in side members PA, PL which are flexibly connected together and to a suspension member CL at their upper ends by links LN, LI and which at their lower ends are connected by a link TL. The side plates are held apart by the ends of the trunnions engaging against the walls of the recesses RS, RC in the side plates, so that, in addition to the clamping pressure applied to the cable by the leverage of the trunnions against the hinge pin PI, further clamping pressure is obtained by the side plates bearing on the ends of the trunnions. In order to increase the grip on the cable in event of breakage of the cable on one side of the clamp the recesses RC, RS in the side plates are enlarged in the vicinity of the supports PO, PR, so that an unbalanced pull on the clamp causes the trunnions to become disengaged from the supports PO, PR and to be pulled into the lower parts of the recesses where the clamping pressure exerted by the side plates is greater.

Patent GB-162938-A (GB)
Title: Improvements in single-trigger mechanism for double-barrel guns
IPC: F41A19/21
Filed: 1920-05-26
Abstract: 162,938. Lindsay, C. W. May 26, 1920. Single-trigger mechanisms.-Relates to single. trigger mechanisms controlled by a momentum block, and consists in employing a springless momentum block and an arcuate detent adapted to lock the trigger after discharge of the first barrel and to be automatically disengaged after the involuntary pull, the detent having a toe which is actuated to re-set the detent on loading the gun. In the form shown, the trigger 10 carries a blade 8 on which is a. slidable selector plate 9 operable by a finger-piece 11 to bring it beneath that one of the two sears 5 which is to be released by the first pull. A rearward extension 15 of the blade 8 is normally engaged by the head of an arcuate detent 7 mounted on a fixed pivot 19 and carrying a pin 14 co-operating with a V-shaped spring cam 21. On the same pivot 19 is mounted a momentum block 6 having a pin 13 adapted to co-operate with the detent 7. Fig. 1 shows the position of the parts before firing. On pulling the trigger, the left-hand sear 5 is released, and the detent 7 is rotated by the extension 15 until, before the plate 8 reaches the right-hand sear, the head of the detent locks in the turned-up end 15', Fig. 2. During this movement, the pin 14 passes to the rear side or the cam 21. The gun recoils, causing the finger to release the trigger, and the momentum block 6 to press the detent 7 forwards until it occupies the same position as that shown in Fig. 1. The gun then rebounds from the shoulder causing the involuntary pull on the trigger to raise the blade 8, which is arrested before reaching the righthand sear by the interlocking again of the parts 7, 15<1> assisted by the pressure of the block 6. The trigger is now released, and the blade 8 falls. leaving the cam 21 free to rotate the detent 7 rearwardly out of the path of the extension 15, so that the detent may offer no obstruction to the rise of the extension when the trigger is pulled to fire the second barrel. On reloading the gun, the blade 8 is pressed down by the sears 5 when these engage the hammers 4, and the extension 15 depresses the toe 16 and rotates the detent back into the position shown in Fig. 1.

Title: Gauge for measuring stresses in earth and the like
Inventor: WHIFFIN ALBERT CHARLES
IPC: E02D1/08
Filed: 1950-06-10
Abstract: 685,941. Electric indicating systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 11, 1951 [June 10, 1950], No. 14536/50. Class 40 (i) [Also in Group XXXVI] Apparatus for measuring the stress in e.g. the earth under a road, comprises a shallow box containing a magnetic wire under tension made to vibrate, by an electromagnet, the frequency of vibration, determined via an electrical pick-up, being indicative of the variation in tension, and thus indicative of the stress. A steel wire 5 (Fig. 1, 2) is stretched between the centre of the top 2 of a shallow steel cylinder 1, and a point on the wall, the tension being adjustable by a screw 7. Two electromagnets consisting of pole pieces 12 and a bar magnet 12a, and windings 16, 17, are secured symmetrically about the wire 5, so that it is maintained vibrating at its natural frequency by connecting the windings 16, 17 as energizing and pick-up coils in the anode and grid circuits of a valve 23 (Fig. 3). The signal in this valve is amplified in RC coupled valves 29, 32, the latter being made to overload so that its output is approximately square-topped, and is coupled through a phase-splitting circuit to two thyratrons 42, 43 in series, whereby the thyratrons are alternately fired to charge and discharge a condenser 35 at a rate determined by the frequency of oscillation of the wire 5. A portion of the total anode current, proportional to the normal vibration frequency, is by-passed by resistors 44, 48, and the remaining current is measured by a meter 45. A relay 53, operated by the anode current of a valve 52 fed with the rectified output of valve 29, short-circuits the meter 45 until the anode current of valve 52 operates the relay. The gauge is buried in the soil, and the local stress deflects the top 2 of box 1. thereby varying the tension in the wire 5, and hence its vibration frequency, as shown by the meter 45. Errors due to temperature variation are eliminated by making the wire 5 and box 1 of the same material, and therefore having the same temperature coefficient.

Title: Improvements in or relating to method and apparatus for producing a screw thread or the like in a workpiece
IPC: B23G7/00
Filed: 1951-06-20
Abstract: 748,541. Removing metal by spark discharge. METHOD X CO. June 20, 1951 [June 21, 1950], No. 14621/51. Class 83 (4). A screw-thread, rifled surface or the like is formed in a workpiece by connecting this to the positive terminal of a direct-current supply and of a condenser, by connecting the negatives to an electrode having a screw-thread of the desired pitch, and effecting relative spiral feed of this electrode towards the work without actual contact, so that a series of discharge sparks disintegrates material from the work. The work 22 may be clamped to a block 20 in a trough 14 which rests on a rubber pad 16 and is filled with mineral or " condenser " oil 62. The hollow electrode 36 is supported by a split nut 32 adjustable on the frame 12 which also carries a bearing 39 for a hollow-spindle, 42 which has a hand-wheel 44 and is secured to the shank 61 of the electrode. One terminal of the current supply 50 and condenser 52 is connected to one of the clamps 23 and the other to the frame 12. A pump 64 circulates the fluid 62 through a pipe 67, the spindle 42 and the electrode 36, which is of brass or other soft metal, and washes away material disintegrated from both electrode and work. The wheel 44 or any equivalent mechanism is operated to keep the gap between work and electrode substantially constant. The operation can be expedited if the work be formed, e.g. by casting, sintering, moulding, &c., with a hole 68. If there is no preformed hole and the thread is only required partway through the work, the remaining core 74, Fig. 3, is broken off finally. For a smooth finish, e.g. by a second operation on the work, a lower amperage and voltage is used and the spark gap may be as small as 0.0005 inch.

Title: Method of determining and controlling the degree of scouring of raw wool and other intermediate or finished textile products
IPC: G01N33/36
Filed: 1946-05-16
Abstract: The degree of scouring of raw wool and other textile products is determined and controlled by taking a weighed sample from the scouring machine and producing from the residual oil and grease adhering to it a cloudy emulsion of the oil or grease in water or aqueous solution, measuring the turbidity of the emulsion to estimate the residual oil and grease content, and adjusting the conditions influencing the scouring so as to maintain the desired degree of scouring.  The oil and grease may be extracted from the sample with an organic solvent which is soluble in water, and the extract mixed with water, or the sample may be agitated with an aqueous detergent solution.  The turbidity may conveniently be measured by comparison with a standard or standards corresponding to wool of known grease content.
