Title: Improvements in and relating to apparatus for the accurate determination of the heartbeat frequency
IPC: G01H3/00
Filed: 1963-06-06
Abstract: 1,046,111. Cardiographs. K. HAMMACHER. June 6, 1963 [Dec. 6, 1962], No. 22529/63. Heading ASK. In apparatus for counting heart beats the timing of predetermined points in one heart cycle is compared with that of the corresponding points of other cycles and counting continues only so long as these are in agreement. The output from a microphone 1,which is receiving heart sounds, is passed through amplifers and filters 2, 3, 4 to a controlling amplifier 5 which corrects unavoidable fluctuations in the heart sounds. The signal then passes to an amplitude discriminator 6 which produces trigger pulses in response to the two peaks in the heart cycle, and these control a flip-flop circuit 9 which, by means of its two working conditions, separates the two pulses for feeding to converters 10, 11 which give outputs the amplitudes of which are dependent on the timing of the pulses. These are in turn passed to a comparator circuit 12 and, if they are found to be correct, a recorder 16 is actuated through an amplifier 14. A square wave generator 7 is also included in the circuit to cut off the operation of the circuit 9 during the unwanted part of each cycle and so avoid fault operation resulting from noise.

Title: Method and machine for making wire terminals
IPC: H01R43/048
Filed: 1966-05-20
Abstract: 1,123,464. Making electrical connections; welding by pressure ; angular bending; jointing by stamping. S. WARNER. 20 May, 1966 [10 Aug., 1965], No. 22558/66. Headings B3A, B3E, B3Q and B3R.  In a method of making an electrical connection a metal strip is fed step-by-step to an operating station, at the end of each step the leading portion of the strip is severed therefrom and formed into a channel section, at least one wire is placed in the channel, the upstanding flanges of which are bent inwardly over the wire and electrically fused together and to the wire. Strip metal stock e is fed from a reel by a reciprocating mechanism actuated by a fluid pressure motor. The leading end of the strip is cut off by co-operating blades 4, 5 and simultaneously formed into a channel section by a forming finger 3 in a die formed by the blade 5 and walls 6, 7. The blade 4 and finger 3 are withdrawn and wires (b), (c), Fig. 9 (not shown), are inserted manually or automatically into the channel. Forming fingers 1, 2 successively bend over the upstanding flanges of the channel section and the finger 3 tightly presses the folded terminal piece around the wires. A welding electrode E mounted on a guide G is advanced by a fluid pressure motor H. When a shoulder 20 abuts a stop 21 continued movement of the piston-rod 14 drives an actuating block against the effect of a spring 24 so that a roller 17 moves a pivoted crimping and fusing head down on to the terminal piece. The fusing circuit may be closed by any suitable means when the electrode head 15 and die wall 7 engage the terminal piece. A fluid pressure operated finger (25) ejects the completed terminal, Fig. 14 (not shown), a piston-rod 31 raises the strip stock e above the level of the die walls 5, 6 and it is advanced by the mechanism D at the commencement of a further operating cycle. The housing 33 of the feed mechanism is slidably mounted in a guide bracket 34 and has an extension 33a connected to a fluid pressure motor 37. As the housing slides in the feed direction, jaws 37, 38 grip the strip as a jaw guide 41 forces them together and during movement in the opposite direction the jaws move apart and slide over the strip.

Abstract: 348,963. Automatic couplings for railway vehicles. NATIONAL MALLEABLE & STEEL CASTINGS CO., 10600, Quincy Avenue, Cleveland, Ohio, U.S.A.- (Assignees of Bazeley, A. J.; 9718, Logan Court, Cleveland, Ohio, U.S.A.) July 26, 1930, No. 22570. Convention date, July 26, 1929. [Class 103 (v).] In an automatic knuckle coupling for railway vehicles of the kind in which the depending leg 3 of the lock D is adapted to operate a two-armed pivoted knuckle-thrower E, the face 4 of the operated arm 5 of the thrower is designed, when the lock is in locking position, Figs. 1 and 6, to extend diagonally forwards from the pivot 7, and, during the raising of the lock, to be swung to a final diagonal rearward position, Figs. 3 and 8, the lock leg 3 being provided with a narrow extension 8 that bears continuously against the thrower arm 5 near its extremity so as thereby to exert a substantially maximum leverage. Preferably the operative face 9 of the extension 8 is curved as shown and maintains a line contact with the face 4, which extends radially from the pivot 7. In order to operate the thrower E the lock is actuated by a two-piece lifter C and pivots about a fulcrum 2, Fig. 3, on the forward face of the lock, a substantially maximum leverage being again obtained by connecting a hook 12 at the end of the lower part 14 of the lifter to an oval trunnion 10 disposed as far as possible to the rear of the lock. The upper part 15 of the lifter has a pin 15a which works in a slot 14a in the lower part 14, and the two parts thus form a toggle, Fig. 1, which forces a shoulder 14b on the part 14 beneath a co-operating shoulder 16 on the coupler-head A so as to effect a lock-tothe-lock, the toggle being straightened out when the lifter is raised, Fig. 3. In its locking position the lock is supported partly on the knuckle thrower E by a seating 18, and partly on ledges 20a, 20b on the tail 20, Fig. 4, of the knuckle B, by means of two laterally projecting shoulders 21, 21a. In such position, the shoulder 21a and ledge 20b slope rearwardly and, by giving the lock a tendency to slide rearwardly, prevent the lug 2 from jamming against the front face of the cavity in the couplerhead when the lock is being raised.

Filed: 1956-07-20
Abstract: 817,873. Valves. SANGSTER, O. B. July 20, 1956, No. 22604/56. Class 135. In a sliding gate valve connecting aligned passageways 12, 14 in a valve body 10, a screw-actuated sliding valve stem 44 carries a pair of channel-shaped plates 126 forming valve members which are pressed apart to engage apertured valve seat discs 22, by a spring 142. The valve members are movably carried on, and spring-pressed downwardly on, an extension 114 of the valve stem 44 by spring-embraced bolts 138 which loosely extend through conical apertures in projections on the stem and allow both rocking and vertical movements of the valve members relative to the valve stem. The extension 114, Fig. 7, has longitudinal notches 116 to receive V-shaped guides on the valve body, and two pairs of ribs 120 with inclined upper surfaces, Fig. 2, engaging correspondingly inclined lugs on the valve members 126. The inclined upper surfaces move the members 126 laterally from their seats as the valve stem rises. Similarly, inclined outer surfaces on the ribs 120 press the members 126 against their seats as the valve is finally closed. The valve seat discs 22 and walls of the bore 16 in the valve body 10 are slightly inclined to the axis of the valve stem, and bevel scraper edges are provided on the lower ends of the members 126. The outward movement of the members 126 under the action of spring 142 is limited by a slotted retainerplate 144. The upper part of the valve body 10 is flanged and bolted to a flanged bonnet 30 with the interposition of a stuffing-box plate 32 slidably supporting the valve stem 44, the plate 32 carrying a conical scraper sleeve 54. Packing 48 in the plate 32 is compressed by the bevelled lower end of a ring 56 adjusted by two or more screws 64 engaging the ring through antifriction means such as a single ball seated in the bottom of each screw. The screws 64 pass through bores and stuffing-boxes in the top of the bonnet 30, the bores preferably being of conical, oval or other shape providing exaggerated clearance facilitating adjustment of the screws. The upper end of the valve stem 44 is threaded to engage a screwed part 78 of an actuating shaft 74 having a hand wheel 76. A collar 80 on the shaft 74 is supported between ball-bearing assemblies in the bormet 30, a closure plate for the bearing being secured by a plate 96 and interposed packing member. Either or both sides of the bonnet 30 are provided. with removable cover-plates giving access to the chamber therein, the chamber being filled with lubricant which may be arranged in a circulating system. In order to allow lubricant to enter the valve stem 44 the bore in the ring 56 through which the stem passes is conical, thereby providing clearance, and transverse passages are formed in the wall of the upper end of the stem. A cup-shaped member 108 on the stem 44 carries a resilient packing-ring co-operating with the scraper 54 to form additional sealing means when the valve is fully open so that the packing 48 may be replaced without danger of leakage.
