Title: Improvements in or relating to fuel injection pumps
Inventor: FRIEDLANDER WILLIAM
IPC: F02M41/12
Filed: 1959-02-24
Abstract: 946,741. Fuel-injection pumps. MONO-CAM Ltd. Feb. 15, 1960 [Feb. 24, 1959; April 7, 1959], Nos. 6403/59 and 11779/59. Heading F1A. A fuel injection pump comprises at least one piston and cylinder pumping assembly in which the effective length of the delivery stroke of the piston is controlled by governor means exposed during the injection stroke of the piston to a liquid pressure which moves the governor means to connect the pumping chamber to a spill passage when the engine speed exceeds that for which the pump is set and wherein the time during which the governor means is exposed to liquid pressure is a function of the time between the commencement of the injection stroke and the end of the immediately preceding injection stroke. As shown in Fig. 1, a piston 1 slidable and rotatable in a cylinder bore 2 to deliver fuel to a four cylinder compression-ignition - engine is formed with an enlargement 20 movable in an enlarged portion 19 of the bore 2. On the injection stroke of the piston 1, fuel admitted to the enlarged portion 19 through an inlet 23 is pumped up a passage 21 and through a non- return valve 22 to admit the fuel beneath a valve body 10 loaded by a spring 12. When the pressure of this fuel reaches a predetermined value the valve body 10 moves upwardly to connect the pump chamber through a passage 7 and an annular chamber 13 to a spill passage 14 whence pump delivery through axial and radial passages 24, 25, and an elongated slot 26 in the piston and a delivery passage 27 ceases. At the same time axial and radial passages 15, 16 in the valve body 10 connect the underside of the valve body with a spill port 51 to prevent any further upward movement of the valve body during the remainder of the injection stroke. On the suction stroke of the piston, the non-return valve 22 closes and fuel from beneath the valve body 10 passes through a restricted outlet adjusted on rotation of the valve body provided by a crescent-shaped valve body recess 17, and a passage 18 to the enlargement 20. If, e.g., the engine speed is in excess of that set by the pump the time between injection strokes is decreased with the result that less fuel passes through the restricted outlet and downward travel of the valve body 10 is reduced so that at the next injection stroke the valve body 10 has less distance to travel before the spill passage 14 is opened resulting in earlier cut-off of pump delivery and consequent reduction in engine speed. Helical grooves 31 in the piston 1 and a spill passage 32 are provided to control spill for the associated engine cylinder at maximum engine load. In a modification, the valve body 10, Fig. 3, is disposed at right angles to the axis of the cylinder bore 2 and an adjustable plug 37 and a control rod 38 adjustable with respect to the plug are fitted to provide a control for maximum engine load. When starting the engine the rod 38 is withdrawn to allow increased travel of the valve body 10 and increased fuel to the engine.

Abstract: 1,100,728. Sawtooth generating circuits- RADIO CORPORATION OF AMERICA. 15 Feb., 1965 [20 Feb., 1964], No. 6473/65. Heading H3P. A self-oscillating field time base for a television receiver comprises a tube 28 in which the screen waveform is fed back to the suppressor in series with a voltage derived from the output transformer and has further feedback from anode to grid via a capacitor. In the field time base shown, capacitor 40 charges from the boosted H.T. supply 53 via resistors 44, 42 providing a linear rise of current in deflection coils 34, 35. The screen voltage exhibits a parabolic fall (C, Fig. 2, not shown) during this time which is differentiated at 66 and superimposed on a waveform obtained from an auxiliary winding 62 on the output transformer 33. When the suppressor 32 becomes sufficiently negative, a regenerative turn-off of anode current occurs, when capacitor 40 re-charges via a grid current path until the anode current again flows, when the cycle is repeated. The circuit is synchronized by negative pulses fed via capacitor 76. The frequency is adjustable by resistor 60 substantially independently of height and linearity adjustments 44, 42.

Title: Strip-feed device
IPC: B21D43/04
Filed: 1958-03-04
Abstract: 836,295. Metal strip feeds. BURNDY CORPORATION. March 4, 1958 [March 18, 1957], No. 6903/58. Class 83 (4). [Also in Group XVI] An apparatus for intermittently feeding strip material to a device for performing an operation thereon, comprises a feeding device rotatable about an axis in order to engage with and disengage from the strip, and reciprocable in the direction of the axis for the purpose of advancing the strip, means adapted to retard reciprocation of the device during rotation, and a rigid operating member reciprocable in a direction substantially perpendicular to the axis of rotation of the feeding device coupled to the feeding device. As shown, the feeding device comprises a lower block 12, Fig. 4, and an upper block 14 which enclose a bolt 16 slidable in a groove 20. A finger 22, Fig. 1, extends laterally of the bolt, while a cam follower 26 secured to the bolt extends through an opening 24 formed by the blocks 12 and 14. The finger 22 engages arms 54 of a strip of integrallyformed connectors 52 each of which in turn is crimped by a pair of dies, not shown, about a conductor and then severed from the strip. A pin 34, Fig. 4, engaging an elongated slot 36 in the block 14 fits into a circumferential groove 38 on the feed bolt at one end and is secured to a friction block 40 at its other end. The block 40 is slidable in a groove 42. A rubber pad 48 is positioned above a bearing strip 46 which frictionally engages the block 40. In operation, as a die 30, Fig. 3 (not shown), moves downwardly, a cam 28 secured to the die actuates the cam follower 26, Fig. 2. The bolt 16 is thus rotated to raise the finger 22 since axial movement of the bolt does not take place because the frictional force between block 40 and strip 46 is greater than the resistance to rotation of the bolt 16. When the cam follower engages the block 12 the bolt is retracted with the finger 22 in raised position. Raising of the die similarly causes the bolt 16 to rotate to lower the finger 22 and then to advance to feed the connectors 52 forwards. The end positions of the bolt 16 may be varied by raising or lowering the position of cam 28 with respect to the die 30; for altering the length of feed the cam may be replaced by one of another inclination, or by arranging for an over travel on the retract stroke.
