Title: Electric fuel pumps
IPC: F02M1/00
Filed: 1939-03-07
Abstract: 527,552. Electric diaphragm pumps. STEWART-WARNER CORPORATION, and WHITTED, J. B. March 7, 1939. No. 7341. [Class 102 (i)] [Also in Group XXXV] In a fuel pump in which a diaphragm is actuated on the suction stroke by an electromagnet and on the return stroke by a spring, a main switch controls the supply of electrical energy to the electromagnet, and secondary switches on opposite sides of the armature of the electromagnet and actuated by movement of the armature, control the main switch. The diaphragm 44 which is grooved at 56 to facilitate bending and preferably is made of synthetic rubber reinforced by a fabric layer, is clamped between upper and lower casings 10, 14 respectively. Fuel from a supply pipe 18 passes through a filter 26 and inlet valve 38 to the diaphragm chamber 42 and is discharged through a valve 57 and passage 58 to the pipe 60. A member 72 closes the lower end of the passage 58, and beneath it the fuel forms a cushion for the fuel entering at 18. The filter is held in place by a spring 27. The diaphragm 44 is moved downwardly by a spring 52 and is raised by the action of an electromagnet 98 on an armature 74 to which the piston rod 50 is detachably secured. In its lower and upper positions the armature closes spring contacts B and A respectively. A normally closed main switch Z adapted to be operated by electromagnets 116, 118 of differing resistances is provided and is shunted by a high resistance N. Another high resistance. C is connected in series with the coil 118. The parts A, B, C, N, Z, 74 and 98 are mounted on a plate 94 which rests on a recess 96 in the casing 10 so that they can be removed as a unit. In operation, on closing the ignition switch 138, the coil 98 is energized and raises the armature 7i and the diaphragm 44 to draw fuel into the casing 14, and causes the contacts B to open. At the end of its upward movement, the armature 74 closes contacts A causing the coil 116 to be energized to open the switch Z so that the diaphragm and armature move downwardly under the action of the spring 52 at the same time opening the circuit of the coil 116 but allowing a smaller but sufficient current to pass through the coil 118 to keep the switch Z open. At the bottom of its movement, the armature closes the contacts B to create a current in coil 116 neutralizing the effect of the coil 118 s) that the switch Z closes and the cycle of operations recommences. The upward pull on the diaphragm is arranged to cease before the diaphragm is taut so that the inertia of the fuel swells out the slack portion thereof. The main switch Z is described in Specification 527,624, [Group XXXVII].

Title: Diaphragm valves
IPC: F16K7/12
Filed: 1955-03-14
Abstract: 794,992. Diaphragm valves. GRINNELL CORPORATION. March 14, 1955 [June 14, 1954], No. 7356/55. Class 135. A diaphragm valve comprises an operating stem on that side of the diaphragm remote from the valve seat having a portion in abutment with resilient means separate from or integral with the diaphragm, actuating mechanism for reciprocating the stem to move the diaphragm towards or away from its seat, a compressor carried by the stem engageable with said remote diaphragm side and a connecting member carried by the diaphragm and projecting from its said remote side to operatively engage the stem. As shown in Fig. 1, the diaphragm 22 is engageable with a seat 30, is formed with a tubular boss 74 in abutment with a screwthreaded stem 38 and carries a connecting member comprising an embedded stud 76 and collar 78. The stud 76 is formed with an elongated slot 82 engageable with a pin 64 which passes through the stem 38 and a compressor 60. On actuation of a hollow screw-threaded bush 34 by a handwheel 46 to move the diaphragm towards its seat, the pin 64 moves out of operative engagement with the stud 76 so that the stud does not damage the diaphragm when the latter is pressed on to its seat. On actuation in the opposite direction the pin 64 engages the stud with lost motion to positively move the diaphragm away from its seat and thus permits the valve to be used in a vacuum system. The diaphragm may be made of natural or synthetic rubber or of plastic material such as trifluorochloroethylene. When the latter material is used owing to its low resilience the diaphragm has to be made thin necessitating the fitting of a backing plate of synthetic rubber. In this case it is the backing plate which engages the stem and the compressor. In a modification, the connecting member comprises the stud 76, and a nut 106, Fig. 8, having a square head 110 which engages with lost motion in a T-slot 112 in the stem 38.

Abstract: 179,027. Ward, A. S. March 11, 1921. Railway carriage doors and the like, fastening automatically; striking-plates for locks.-The axle of the wheels of a railway carriage has two sets of oppositely-directed pawls which maintain a T-headed vertically-mounted member in a position at right-angles to its normal position to shoot and hold bolts on the doors while the train is in motion. The pawls b turn the T-headed member 3 through a right-angle whatever the direction of motion of the train, by engaging the T-head d. This turn of 90‹ is imparted to an horizontal rod h by the pinion f mounted on the shaft of the T-headed member, and the rack g on the rod. The rod h actuates a vertical rod l which shoots or retracts bolts m. The T-headed member is returned to its normal position by the torsion spring e. In order to open the doors when the train is in motion, the bolts m are constructed to engage behind spring-pressed bevelled catches p mounted on the door frame. These catches can be moved apart to free the bolt by inserting a key in the hole 1 and turning it to operate the followers 2.

Title: Electronic Halftone Image Generator
Inventor: KLENSCH RICHARD JOSEPH
IPC: H04N3/32
Filed: 1968-02-20
Abstract: 1,183,419. Facsimile systems. R.C.A. CORPORATION. 20 Feb., 1968 [23 Feb., 1967], No. 8284/68. Heading H4F. To produce a line width modulated halftone image of a continuous tone image on a transparency 12, the transparency is scanned by a flying spot scanner 20, and the image signals generated by detector 38 are amplified 40 and modulated 48 by a carrier signal from generator 44, the carrier signal being phase shifted by + 45 degrees. The amplitude of the output modulated signal is a function of the amplitude of the image signal and hence the tone of the transparency. The modulated signal is used to vary the width of the scanlines on cathode-ray display tube 14 by adding it to the vertical deflection signal in sununing amplifier 58 and applying the summed output to the vertical deflection coil 60 of display tube 14. Capacitor 56 removes the D.C. component and limiter 57 limits the modulated signal so that alternations in one scanline do not overlap the alternations in adjacent scanlines on the face of tube 14. The scanning electron beam 62 has different velocities depending upon the portion of the alternating, e.g. sinewave, cycle the beam is traversing, and these differences in velocity produce unequal exposures on photographic film 16 which is exposed to the display tube face 14. To compensate for this intensity variation the image signals are modulated 66 by the carrier from generator 44 phase shifted by - 45 degrees so that the output wave is 90 degrees out of phase with the output of modulator 48. The output from modulator 66 is full wave rectified 70 and coupled to a summing amplifier 72 before being applied to the control grid of tube 14. Thus the compensation circuit 64 intensifies the scanning spot when the beam 62 is rapidly deflected and reduces the intensity when the beam is slowly deflected. A tone expander 80 is arranged to turn on the scanning beam 62 only when the image signal is above a predetermined threshold level, i.e. beam 62 is turned off when dark tones are scanned. Circuit 80 operates to expand the tone range up to a threshold level determined by diode 104, a threshold level being necessary to prevent highly deflected signals from being brighter than smaller deflected image signals. Instead of a raster scan in tube 14 a single line scan may be utilized, film 16 being moved. Stored signals from memory 110 may be displayed. Wavy line instead of straight line halftone image may be produced by coupling a low frequency oscillator 112 to amplifier 58 and to the flying spot scanner 20, and the resulting undulating scanlines may be broken at random to create a mezzo effect by applying the low frequency oscillations from oscillator 112 and an aperiodic wave from a noise generator 114 to a modulator 116.
