Abstract: 777,012. Fuel injection pumps. BOSCH GES., R. Aug. 22, 1955 [Sept. 11, 1954], No. 24065/55. Class 102(1) In a fuel injection pump having a rotatable driving shaft 3 coupled with. a cam disc 18 having a cam tack on one face and adapted to drive a combined injection pump and distributer member 22 with both rotary and axially reciprocatory movement, a fuel feed pump for the injection pump comprising a piston 5 and cylindrical bore 4 is disposed within the shaft 3 the piston 5 being coupled to the distributer member 22 so as to follow the reciprocatory movement thereof. On the outward stroke of the piston 5 the cylinder 4 communicates by a port 6 with a port 7 and the inlet passage 10; on the inward stroke the port 6 communicates with an outlet port 8 and a chamber 12. The cam disc 18 is driven from the shaft 3 by means of a tongue 19 which also has a T slot engaged by the piston 5. Rotatably mounted on the shaft 3 is a; control ring 15 on which are mounted rollers engaging the cam face of the disc 18. A spring 43 maintains contact betwen the cam face and the rollers. The ring 15 is angularly adjustable by means of a pin 45 engaging with an inclined slot in a member 49 connected to a piston 48 the upper end of which is subjected to pressure in the chamber 12, this pressure being opposed by a spring 51. The member 22 rotates and reciprocates in a pump member 21 having a fuel inlet 37 connected through a filter 75 having a release valve 76, to a fuel outlet 73 communicating with the chamber 12. The inlet 37 communicates with a bore 36 via a throttle 39 adjustable by means of a governor 62 driven through gearing 56, 55 from the shaft 3. On the suction stroke of the member 22 a port 34 therein communicates with the passage 36 which communication is cut off during the pressure stroke and delivery takes place through a valve 29 to a chamber 32 within the member 22 which chamber 32 communicates via a port 35 with the fuel outlet passages 40 as the member 22 rotates. The governor spring- 63 is adjustable by means of a lever 67 and adjustable stops 68, 69. The governor housing 59 and pump housing 21 with the associated components may be readily removed and replaced.

Abstract: 150,683. Blickensderfer Manufacturing Co., (Assignees of Roberts, E. R.) Nov. 19, 1918, [Convention date]. Line-spacing mechanism.-The spindle 97 of the line-spacing lever 105 is mounted in a bracket 99 on the paper-carriage 55, and is provided with a finger 96 having sliding engagement in a hole 98 in a rocking plate 92 that is mounted on the platen shaft and carries a dog 91. The lever 105 is substantially horizontal when at rest and substantially vertical at the end of its stroke, and the sliding engagement between the finger 96 and the plate 92 provides for decreasing leverage on the plate as the lever 105 is raised. The dog 91 is urged towards the ratchet-wheel 90 by a spring 93, but is normally held out of engagement by a stop 95 that abuts on the tail 94 of the dog. The spacing is adjusted by means of a stop-plate 100 which can be moved laterally to bring either of two shoulders 103, 104 into the path of the pawl 91. The stop-plate is secured by means of a screw 102 passing through a slot.

Patent GB-757664-A (GB)
Title: Improvements in methods of extruding polytetrafluoroethylene
IPC: B29C48/05
Filed: 1954-08-20
Abstract: Pure, unbaked polytetrafluorethylene is heated in an extruder to a temperature higher than its normal melting point, while sufficient pressure is applied to prevent it from melting, and is forced through the die at that temperature, the pressure decreasing as the material passes through the die, causing the extrudate to melt.  For a temperature range of 350 DEG -375 DEG C. the required pressure range is 7,500-10,000 lb./sq. in.  The unbaked polytetrafluoroethylene may be in the grannular or agglommerated colloidal form, or it may be introduced into the extruder cylinder as an unbaked preform.  Small proportions of stabilizer or coloured pigments may be added to the material.  Multiple ram extruders may be used.  The process may be continuous or intermittent, the die in the latter case being blocked while the material is heated in the cylinder.  An example is given of coating wire by the process.

In an hydraulic motor comprising a wobbrer member 11 mounted on a crank-shaft 1 and coupled to pistons 8 reciprocating in a fixed cylinder block, the supply and exhaust of liquid is controlled by a pair of distributers 16 and 21. The distributer 16 comprises a disc eccentrically mounted on the shaft 1 and provided with inner and outer upper and lower communicating grooves which rotates between fixed port blocks 17 and 18. The distributer 16 provides alternating connections of inlet passage 19 and outlet passage 20 to the cylinders in the cylinder block under the control of distributer 21. The distributer (21), Fig. 1 (not shown), comprises a disc rotatable selectively to any one of three positions by means of a rack (24) engaging teeth on the disc. In one position (P1), Fig. 1 (not shown), both ends of each of the cylinders are alternately connected to the supply and exhaust, in a second position (P2), Fig. 2 (not shown), the ends of the cylinders adjacent the piston rods are permanently connected to the supply, by means passages in the distributer (21) communicating with a central chamber (81) in communication with the supply, and the ends of the cylinders remote from the piston rods are alternately connected to supply and exhaust, and in a third position (P3), Fig. 3 (not shown), the ends of the cylinders adjacent the piston rods are alternately connected to supply and exhaust and the ends of the cylinders remote from the piston rods are permanently connected to exhaust through channels in the distributer (21). A greater range of outputs may be obtained by associating groups of cylinders each with a selectively adjustable distributer (21). A pair of selectively adjustable distributers (21) could be replaced by a single distributer providing the same range of outputs.

The rollers A, D align the documents with the rest of the stack as they arrive and feed the leading edges thereof up to an end stop E. The inclination of the roller A holds the lower edges of the incoming documents in firm contact with the base of the receptacle for the stack and thereby prevents the documents from being deflected upwards as they join the stack. The roller D may be inlaid with spaced rings of friction material. The device may be used for documents piled on edge or fed into the bottom of a stack.

Abstract: 953,545. Magnetic storage devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 19, 1960 [July 28, 1959], No. 25081/60. Heading H1T. [Also in Division H3] A rotating magnetic field, the direction of which is representative of a binary digit value, is produced in a thin magnetic film. As shown in Fig. 5, a thin film 10 composed of 83% nickel, 17% iron is of the order of 2600 Angstroms thick and has windings 16 and 18 respectively arranged perpendicular to and parallel with the easy axis of magnetization 12. Winding 16 is connected to an alternating supply 20 and induces a voltage in winding 18 which is tuned to the supply frequency by a condenser C. Under these conditions it is stated that a rotating magnetic field of the supply frequency is produced in the plane of the film, the direction of rotation being initially arbitrary. If, however, a signal pulse is applied to terminal 21 of winding 18 or to an additional winding 26 arranged in the plane of the film, a direction of field rotation is established which depends on the pulse polarity in relation to the field position at the time of application. The same result is obtained by the use of an alternating signal of the same frequency as the supply and having a particular phase or antiphase relationship depending on the digit to be stored. When the required direction of rotation is established, the phase of the voltage induced in winding 18 with respect to the supply is a continuous indication of the stored binary value. The properties of the arrangement are also such that if the alternating supply is interrupted, the rotational mode existing before interruption is re-established when the supply is subsequently reapplied. Specification 922,602 is referred to.
