Title: Pressure responsive valve for fuel pumps
IPC: F02M41/14
Filed: 1953-03-31
Abstract: 737,706. Rotary pumps. ROOSA, V. D. March 31, 1953 [April 4, 1952], No. 8869/53. Class 110 (2). [Also in Groups XXVIII and XXIX]  A fuel feed pump 20 of the gear or sliding vane type has a pressure-responsive valve in the form of a piston 130 slidable in a passageway connecting the inlet and outlet slides of the pump, the passageway being normally blocked by the piston but opened on movement of the piston in either direction from its normal position under the influence of the pressure differential between the two sides of the pump. As shown, the pump has vanes 26 sliding in a rotor 22 connected to the distributing member 16 of a fuel injection pump 78 (see Group XXVIII) driven from the engine through a coupling 94. The passageway is formed as a tubular member 106 mounted in coaxially spaced relation in a blind bore 100 in the end plate 28 of the pump casing 10. The bore 100 is closed by a plug 122 against which the tube 106 is pressed by a spring 120. The tube 106 has external bosses 108, 110 with recesses for packing. Orifices 124, 126 are arranged at opposite sides of the boss 108. The orifice 124 communicates with the delivery of the feed pump 20 by a bore 104 and an arcuate recess 46. The latter is connected through ports 44, 42 with the inlet 56 of the main fuel injection pump 78. The orifice 126 is connected through ports 102, 36 with the liquid fuel supply and through ports 102, 38, and an arcuate recess with inlet of the feed pump 20. The inlet pressure of the feed pump normally acts on the rear of the piston 130 and is aided by a spring 132. If the output of the feed pump rises, the delivery pressure thereof forces the piston 130 to uncover the port 126 and so by-pass fuel back to the inlet side of the feed pump. When the pump is being primed before starting, fuel under pressure is admitted by the port 36 and acts through the orifice 128 on the rear face of the piston so that it is displaced to opposite end of the tube 106 against the spring 120 and opens a connection between the orifices 124, 126.

Title: Control system for high speed printers
IPC: G06K15/07
Filed: 1962-03-06
Abstract: 1,006,699. Electric selective signalling. ANELEX CORPORATION. March 6, 1963 [March 8, 1962], No. 9025/63. Heading G4H. [Also in Division B6] A printer hammer control system comprises a capacitor C7; a first switching device S1 which on receipt of a first and a second signal respectively charges and ceases to charge the capacitor C7; and a second switching device S2 adapted to discharge the capacitor C7 through a coil HC1 to actuate the printer hammer. In Figs. 1, 2 (Fig. 1, not shown) a line of n characters is printed in one revolution of a set of n printing wheels, two wheels with magnetically-detected teeth being provided on the printing wheel shaft to produce on index pulse every rev. and a character clock pulse as each of the sixteen possible characters comes under the printing hammers. The character clock pulses are fed to a binary counter the inverse outputs of the four stages of which provide an indication of the character in printing position in inverted binary code. This indication is compared in n comparators CP1, CP2 ... with binary-coded representations of the required characters which are stored in switches. Each comparator, e.g. CP1, consists of four AND-gates A7 . . . A10 feeding a unit LU1 which acts as a NOR gate on arrival of one of the character clock pulses at an input j. Each comparator CP1 ... thus provides an output pulse to a corresponding hammer driver circuit DR1 ... whenever no pair of compared input bits consists of two 1s. The first of these pulses makes a silicon controlled rectifier S2 conduct to discharge a capacitor C7 through a hammer driver coil, e.g. HC1. At the end of the cycle (rev.), the counter provides a pulse to an input a of a unit 27 thus making a siliconcontrolled rectifier S 1 conduct and produce voltage across a resistor R1. This charges the capacitors C7 in all the hammer driver circuits DR1....When a switch is closed to start the printing of the next line, a pulse arrives at input b of unit 27 and cuts off rectifier S1 thus stopping the charging of the capacitors C7. Since capacitor recharging is thus done at the end of the cycle only the first pulse from each comparator CP1, CP2 ... in a given cycle is effective to print. The code representing the characters in position may be other than inverted binary, a set of coded toothed wheels on the printing wheel shaft providing the signals directly. Fig. 3 (not shown) shows a modification in which the n characters to be printed arrive in four-bit parallel binary-coded form, serially by character, and are read into four n-stage magneticcore shift registers by a sequence of n clock pulses arriving with the data. As before, a counter supplies a four-bit parallel invertedbinary-coded representation of the character in printing position, and each 1 in this representation reads out (and re-writes) as a pulse every 1 stored in a corresponding one of the shift registers. The read-out bits pass to n units of the type LU1 (Fig. 2) which control hammer driver circuits as before. Specification 765,059 is referred to.

Title: Improvements in attenuators for use with wave guides
IPC: H01P1/22
Filed: 1946-03-28
Abstract: 617,092. Attenuators. WESTERN ELECTRIC CO., Inc. March 28, 1946, No. 9663. Convention date, March 30, 1945. Addition to 576,145. [Class 40 (viii)] A wave-guide attenuator of the kind described in the parent Specification comprises two resistive elements longitudinally positioned opposite each other within the section of wave-guide at distances from the respective sides of the guide so related that the attenuation has a minimum variation over a selected range of frequencies. The resistive elements are in the form of vanes 2, 3 pointed at the ends to reduce reflection and mounted parallel to the narrow walls 4 of a wave-guide section 1. The elements are mounted on rods 6 which pass freely through sleeves 9 dimensioned to reduce loss of energy, and are held at the ends in slots 11 in yokes 12 which are arranged to slide but not rotate due to interengaging parts 14, 16. Each yoke 12 is connected to an arm 18 slidable in a groove on the upper surface of the guide. The arms 18 are urged inwards by springs 25 so that the ends of extensions 22 engage the peripheries of respective cams 23, 24 rotatable by a spindle 26 carrying a scale 27. Rotation of spindle 26 thus causes elements 2, 3 to move together either towards or away from the guide walls. The cams 23, 24 are so dimensioned that the elements are always at different distances from the guide walls. This gives a linear relation between attenuation and rotation of scale 27 over a considerable range of frequency. In a modification, the above effect can be obtained over a limited range of frequency and attenuation by fixing one of the vanes and moving the other.
