Title: Improvements in or relating to liquid pressure power generating units or pumps
IPC: F15B11/02
Filed: 1948-08-30
Abstract: 660,276. Gear pumps. BORG-WARNER CORPORATION. Aug. 30, 1948 [Sept. 18, 1947], No. 22792/48. Class 110(ii) [Also in Group XXIX] A plant comprising two or more fixed displacement gear pumps P<SP>1</SP>, P<SP>2</SP> has all pumps operating over a certain delivery pressure range but over a second pressure range, one (or more) pump is cut out the remainder continuing to operate. A pump is (or are) cut out by the axial movement of one end cheek 21, Fig. 2, due to release of pressure in a chamber 21e by valve means. The delivery pressure of the pump P<SP>2</SP> remaining in operation maintains a control valve open until it is desired to reload the unloaded pump P<SP>1</SP>. The pump P<SP>2</SP> alone may continue to deliver a low volume of liquid at a high pressure after the two pumps have delivered a large volume at lower pressure. The pumps P 1 , P<SP>2</SP> have a common inlet 12, and a common delivery 13 and may supply a motor M<SP>1</SP>, Fig. 7, with a large volume of liquid for most of its piston stroke, the second pump then maintaining the piston in its end-ofstroke position. At the end of the first pressure range the delivery pressure acts on a piston 40a causing a valve 38 to open and relieve the pressure in the chamber 21e. No further delivery then takes place past check valve 16a. A relief valve R' opens when the pressure rises above a predetermined higher figure. The areas of the valve 38 and the back of piston 40b are equal so securing balance of forces from fluid flowing through a passage 11a from the chamber 21e. To reverse the motor M<SP>1</SP>, a valve 41a is changed over to relieve the pressure from the underside of the piston and delivered to the other side causing valve 38 to close and pressure to be built up in chamber M to cut-in the pump P,. A valve 45, pressed upon by a spring 45a, maintains a higher pressure acting on the bushes 33 than the pressure at the pump inlet. In a modified arrangement the second pump capacity is larger than that of P<SP>2</SP>. Fig 11 shows a simplified arrangement with the combined deliveries of pumps P<SP>1</SP>, P<SP>2</SP> acting on a piston 50a to lift a valve 50, first unloading the pump P<SP>1</SP> by moving its end bushes. Further upward movement of the piston 50a allows discharge of pressure fluid back to the suction side of the pump. In a further pumping apparatus, the second pump is a piston pump actuated by an eccentric. Annular relief recesses 20c, 21c, Fig. 2, relieve excessive pressures in the pump P' through channels 20d, 21d leading to the suction side, to prevent axial movement of the bushing flanges 21a thus cutting out the pump. A spring 17c acts to prevent axial movement of the gear 17 from a flange 20a when the bushing flange 21a is unloaded. U.S.A. Specification 2,420,622 is referred to.

Abstract: 230,121. Little Co., A. E., and Reed, J. H. Sept. 11, 1923. Machines using continuous wire.-In a shoe in which an intact or unchanelled insole is employed the upper 25 is connected to the insole 26 by means of metallic fasteners, preferably staples S of the form shown in Fig. 3, which extend through the upper and only part way through the insole and are anchored in the latter. An outsole 27 is attached to the upper and insole by through-stitching and preferably by a lockstitch seam 28. The staples S have inwardly curved prongs 11 and are driven through a fastener throat 15 having converging walls 18. The driver comprises two members 16 pivoted to a plunger 17 and formed at the outer sides of their lower ends with projections 20 which engage the shanks of the staples. This formation of the staple-inserting mechanism causes the prongs of the staples to be further turned inwardly as they penetrate the insole and to be thereby clinched within the insole. The staples may be set transversely, or parallel, to the edge of the upper. Specification 24100/95 is referred to.

Abstract: 1458711 Anti-skid brake control NISSAN MOTOR CO Ltd 22 May 1974 [11 July 1973] 22841/74 Heading F2F A comparator 40 compares signals from first and second computing means 32, 46 respectively, to supply a digital signal for brake release when the first means signal is greater than the other signal; the first computing means provides a signal comprising a sensed vehicle speed signal voltage minus a first variable reference voltage related to the vehicle speed voltage, and the second computing means provides a signal comprising a braked wheel rotational speed signal voltage plus a voltage proportional to the rate of increase of the wheel speed voltage if such increase occurs, obtained from a differentiator 42, and minus a voltage proportional to the rate of decrease of the wheel speed voltage, if such occurs, obtained from a differentiator 44. Vehicle speed is sensed by a generator on an unbraked wheel or by a Doppler radar and the signal Ev is fed to the computing means 32 in combination with a fixed voltage signal Ec and a proportional signal to the speed signal these latter signals being subtracted from the speed signal for the output to the comparator 40. Thus, the compared signal has such a difference from the vehicle speed that comparison is made in the peak wheel adhesion area (0À15 to 0À25 wheel slip relative to the vehicle). Wheel speed signal Ew is fed to the computing means 46 in conjunction with the signal proportional the wheel deceleration or the signal proportional to wheel acceleration, whichever occurs, the former signal being subtracted and the latter being added to the speed signal. This means that the initiation and the cessation of the digital signal to an actuator 18 for brake release is brought forward in both cases to offset the delays which occur in brake pressure variation in the actuator when acted upon by the signal.

Title: Improvements in or relating to control systems for single phase electric motors
IPC: H02P23/00
Filed: 1953-08-19
Abstract: 743,291. Control of A.C. motors. GENERAL ELECTRIC CO., Ltd., and LAMBERT, R. A. Aug. 10, 1954 [Aug. 19, 1953], No. 22889/53. Class 38(3) A split-phase motor, having a main winding 1 and an auxiliary winding 2 which is suitably proportioned for phase displacement, is started in one direction when a push-button switch L1 or L2 is moved to energize a relay winding CL. 4 A make-before-break contact CL1 is thereby actuated to establish a holding circuit for the coil CL independently of cen- 4 trifugal switch contacts 3, and subsequently to disconnect the relay winding from these contacts. At the end of the starting period the contacts 3 are opened to disconnect the starting winding of the motor, but the relay CL/4 remains energized until the push-button is released. Reverse rotation is obtained by operation of push-buttons Rl or R2 to energize relay coil CR, the arrangement being such 4 that only one push-button is effective,at a time. If the motor is running in one sense and reversal of its direction is required, then the operated push-button L1. L2, or R1, R2, is released and the other switch R1, R2, or L1. L2, operated. Release of the one switch interrupts the circuit of the energized relay and the main winding 1 is de-energized. None of the pushbuttons are effective to reconnect the coil of the appropriate relay across the supplylines until the motor has decelerated to reclose the contacts 3. Reclosure of these contacts allows the motor to be started in the selected direction according to which push-button has been actuated. The starting winding may be reversed instead of the main winding, and the pushbutton switches replaced by a two-position switch. Load-actuated limit switches 7 and 8 are provided. According to the Provisional Specification, the auxiliary winding of the motor may be connected in series with 'capacitors of different values for starting and running.

[Also in Group XXI] In filling the cavity of a hollow body, e.g. a mould for a shell charge, with an explosive, a molten component or components of the explosive and a solid component or components, consisting of discrete particles, e.g. flakes, powder, and/or granules, are sequentially introduced into, and mixed under pressure in, the cavity under such mutual temperature conditions that the molten component is solidified, by heat exchange with the solid component, while provision is made for the escape of air, to form a solid non-blistered filling in the cavity. In Fig. 1 shells 1 preheated to 60‹C. are fed by conveyer 2 to a point below dispensing device 4, kept at 85‹-90‹C. by a water jacket, and supplied with molten T.N.T. from melter 5, which feeds a measured quantity of molten T.N.T. into the shell. The shell is passed by hydraulically operated gripping tool 11 through hydraulically operated door 13 in wall 9 to hydraulic press 15 and gripping tool 11 is retracted and door 13 closed. Flake T.N.T. from container 19 is fed to hydraulically operated tiltable measuring bowl 22 and is tipped thence through tube 23 into heating apparatus 24 at 20‹-70‹C., whence the heated flake passes to hopper 17. From hopper 17, the flake T.N.T. passes through bore in the filling member 16, which is pressed into the nose opening of the shell, into the shell and plunger 27 compresses the flake into the molten T.N.T. at 250-400 kg./sq. cm. Clearance between plunger 27 and the filling member bore permit air escapage, and the filling solidifies, and the shell is conveyed away. The plunger 27 may be shaped to form a small depression in the filling for priming composition. In Fig. 3 shells 1 are conveyed by 2 and have a T.N.T. plate 35 positioned over base hole 31. Hydraulically operated funnel 32 is lowered into the nose hole 30 and T.N.T. flakes are fed from container 34 into the shell. The shell is passed by the same means as in Fig. 1 to resilient support 37 with base hole 31 in register with molten T.N.T. injector nozzle 38, which has a molten T.N.T. container 39 maintained at the required temperature by a water jacket. Hydraulically operated plunger 40 is moved down in the nose hole of the shell and molten T.N.T. is injected under hydraulic pressure through 38 into the base of the shell. Plunger 40 may be water cooled and air is released through clearance between it and the nose hole 30. The charge solidifies and the shell is conveyed away. Plunger 40 may be shaped to cause a depression in the filling for priming composition and nozzle 38 may cause an impression for a tracer. A charge consisting of several different components can be made provided at least one is fusible. The proportion of solid to liquid T.N.T. may vary from 3 : 2 to 2 : 3, preferably 1 : 1.
