Title: Improvements relating to fire extinguishers
IPC: A62C11/00
Filed: 1931-12-02
Abstract: 384,080. Fire-extinguishers; pumps. JONES, L. M., 59, Peckham Grove, London. Dec. 2, 1931, No. 33440. [Class 47 (ii).] In a fire-extinguisher of the type in which a pump is contained within a container A for extinguishing fluid and in which valves are so arranged that the pump delivers, on operation of the handle, in any -position of the container, the handle K is of hollow globular form and acts as a compression chamber to provide for continuity of flow. The container A has a central delivery tube B on which a barrel D rotates freely ; the barrel D has suspended therefrom a valve chamber E containing ball valves F at each end connected by a gravity operating rod G which opens whichever valve is in the lower position. The piston H sliding inside the barrel D is operated by a hollow rod J carried by the handle and liquid is delivered into the tube B at the end L during the reciprocation of the handle. The end L is normally held closed by a valve M which seats on the end of the tube when the handle is held in closed position in the head N by a bayonet or like catch b. The handle encloses a tubular member a secured to the piston-rod J and has an end cap C which acts as the abutment for a spring d bearing upon the valve M. The spring d is guided in the member a by ribs e leaving four side channels h, and holes fare provided in the member a as near as possible to the centre of gravity of the handle. In operation of the pump the parts move to the position shown in Fig. 2 ; the valve M is lifted off the delivery tube B and sits in the hollow rod J. Fluid passes through V-slots g in the rod J, up the channels h and out of the holes f into the hollow handle K and thus compresses the air therein.

Title: Improvements in Throttle Devices.
IPC: F15B13/00
Filed: 1967-07-21
Abstract: 1,164,233. Fluid regulation. STAHLWERKE BRUNINGHAUS G. m. b. H. July 21, 1967 [Aug. 17, 1966], No.33679/67. Heading G3H. A fluid throttling device comprises a tube 3 having an outlet 11a from which fluid issues against a diaphragm 10a carried by a member 7a which can be screwed in or out of block 6a to adjust gap 5a. A bore 14a admits fluid at the reduced pressure to the rear of the diaphragm so that its movement is determined by the pressure difference between the throttled and unthrottled fluid. A similar throttle is provided at the other end of casing 1 to operate when fluid is directed to port 5a instead of port 5. Under these conditions the tube 3 is moved to the right by the pressure of the fluid to set throttle gap S and open gap Sa. The tube 3 is of brass and the casing 1 is of nickel-iron alloy to compensate for temperature rises.

Title: Improvements in sewing machines
IPC: D05B3/14
Filed: 1934-11-24
Abstract: 425,587. Sewing-machines. FAIRWEATHER, W. C., 65, Chancery Lane, London.- (Singer Manufacturing Co. ; Elizabeth, New Jersey, U.S.A.) Nov. 24, 1934, No. 33836. [Class 112] In a hand-driven machine adjustable for attaching buttons with two or four holes, means are provided for stopping the machine after completion of a predetermined number of stitches. To start the operation, the fabric is inserted beneath the button clasp and the button inserted in the clasp. The clamp is then lowered on the fabric by pressing on a finger lever 236. This causes the return of the thread pull-off 189 by the yielding engagement thereon of a spring element and it also causes the release of the thread clamp 200. The arm 146 is adjusted to the correct position for two or four hole buttons as described in Specification 425,588. The stop-motion button 127 is depressed to release the stop-pin 120 from the hole 121 in the cam disc 86 so that the sewing may be effected by turning the crank 3. The crank 3 is turned sufficiently to produce a single rotation of the cams 86, 87 whereupon the stop pin 120 springs into the hole 121 to stop the sewing operation after a predetermined member of stitches have been placed in the holes of the button, and the knotting stitch has been made. In the case of a four-hole button, an arm is moved to its forward position before the machine is started as described in Specification 426,588. A predetermined number of stitches are placed through one pair of holes in the button after which the button holder is moved automatically to present the other pair of holes to the needle and the stitching continued. On completion of the sewing operation, the finger lever 236 is raised, raising the button clamp 57 and breaking the thread. To avoid the necessity of holding the push-button depressed till the hand-crank 3 is turned sufficiently to carry the stop-hole in the feed cam out of register with the stop-pin of the stop arm, an alternative construction is described, Fig. 26, in which, when the arm 325 is shifted to starting position, it will be automatically shifted laterally to carry its stop pin 328 out of register with the stop hole 329 in the feed cam. For this purpose the stop arm 325 is capable of a slight rocking motion in a guide channel 324 so that when the machine is stopped, the arm 325 is rocked to carry the pin out of register with the hole.

Title: Improvements relating to Pulse Generating Circuit Arrangements
Inventor: SMITH DENNIS CLAYTON
IPC: H03K3/284
Filed: 1965-08-06
Abstract: 1,161,311. Converting. PLESSEY CO. Ltd. 8 Aug., 1966 [6 Aug., 1965], No. 33875/65. Heading H2F. [Also in Divisions H3 and H4] In a free-running pulse generating circuit comprising a monostable device M, having its quasistable (unstable) state variable with operating frequency or triggering frequency, with a current integrating means RF/2, C2 (Fig. 4) connected in a feedback path between the output and input of the monostable device, the integrating means is effective upon the monostable device returning from its quasi-stable state to its stable state to delay the next successive switching operation of the monostable device to its next quasi stable state so as to afford a predetermined ratio between the quasistable and stable periods of the device. The monostable device M may consist of two complementary transistors as disclosed in Specification 1,149,239, and as shown by the monostable circuit in Fig. 8, which can be used as a pulse width modulator having a transistor power output stage. An energy storage means in the form of a resistor and capacitor connected in the biasing circuit to one of these transistors enables the quasi-stable state to be varied in dependence on the triggering frequency. Control of the mark-space ratio may be effected by injecting current into the feedback circuit between the integrating means and the input to the monostable device. As shown in Fig. 4, the monostable device M is connected in circuit with two inverting amplifiers A1 and A2. When the monostable device is triggered into its quasi-stable state its output is antiphase to the triggering signal so that the feedback resistor RF applies negative feedback to the input. The pulse generator may be used as a variable D.C. power supply by smoothing the output.

Abstract: 779,071. Injection-moulding machines. STOKES MACHINE CO., F. J. Nov. 25, 1954 [Dec. 7, 1953; Nov. 1, 1954], No. 34239/54. Class 87(2). Plastic material is forced by a plunger from an injection cylinder 16, Fig. 9, through a nozzle 18 into a heated chamber 76 in a plate 70 that is secured to fixed platen 24. From chamber 76 the material passes, as shown in Fig. 6, through apertures 91 in fixed die plate 39 into mould cavity 80, 81. Then, Fig. 7, pins 84 move to the left to block up the apertures 91. When the material in the mould cavity has solidified by cooling, the die plates 39, 40 part, and the pins 84 may advance further to the left, as shown in Fig. 9, to detach the moulded articles from die plate 39. Alternatively, the pins may not serve to detach the moulded articles, this being done by separate knock-out pins : or both the pins 84 and knock-out pins may be used for this purpose. The pins 84 are secured to a plate 72 which moves horizontally in a space A between the chambered plate 70 and the fixed platen 24. Each pin is guided in its reciprocatory movements by fins extending inwardly from the walls of bushings 78 forming part of chamber 76. The chambered plate 70 is heated by electrical resistances 86 to keep the material therein fluid. The die plates 39, 40 are cooled by liquid. Heat insulation 87, Fig. 9, or an air space, is disposed between the hot plate 70 and the cooled mould half 39. The plate 72 is moved by hydraulic pistons 73. When pins 84 move to the closed position of Fig. 7 they are arrested in the correct position by limit pins 90, Fig. 9, carried by the pin-supporting plate 72. The moulded articles are detached from die plate 40 by ejector pins 37. Any particles or moulded articles which may not have fallen clear of the die plates into a hopper are stripped from pins 37 by a comb 45, Fig. 1 (not shown) that is inserted from the side by a hydraulic piston rod. Material is fed from hopper 10 into injection cylinder 16 by a piston 11 moved by a rod 11<SP>1</SP> connected to the injection plunger 14. The injection assembly may be advanced or retracted by means of a wheel 101 and spindle 102.
