Title: Improvements in or relating to vehicles having hydraulic power transmitters
IPC: F16D33/14
Filed: 1938-08-12
Abstract: 517,989. Hydraulic transmission of power. SINCLAIR, H., and BASEBE, A. C. Aug. 12, 1938, No. 23866. [Class 69 (ii)] Motor vehicles are fitted with hydraulic power transmitters of the kind described in Specification 493,703, which are inserted between the engine and gear box 10. The transmitter comprises an impeller member 13 driven by the crankshaft 14, a runner 15 secured to the input shaft 16 of the gear box 10, and a cover plate 35 connected to the impeller and formed with a drainage aperture 36, and is constructed with a reservoir chamber R situated between the plate 35 and a casing 18, 18A, 18B secured to the impeller member, the effective maximum capacity of the chamber R being between 50 and 70 per cent. of the normal liquid content of the working- chamber, e.g., 60 per cent. A rapid-emptying valve 29 is arranged between the working- chamber and the chamber R, and this is. operated to permit liquid to leave the working-chamber when the car is stopped with the engine running or when changing into reverse. This valve is operated by depressing a foot-lever 45, or when a handbrake lever 57 is operated, and in each case a lever 42 acts on a shifting-ring 23 attached to a sleeve 20 mounted so as to be capable of sliding on the shaft 16. The movement of the sleeve 20 to the left forces open the valve disc 29 against the action of a spring 30, and the sleeve which is normally held stationary by brake members 24, 25 is thus free to rotate and carry with it a pair of scoop tubes 26 which are normally inactive, and an additional scoop 26A, Fig. 4, the mouth of which extends into the bulge 18C in the casing 18 and which acts to return to the working-chamber liquid which drains through the aperture 36. After the valve has been opened, all the scoops act to return the fluid to the working-chamber. The scoops 26 are fitted with non-return valves to prevent escape back into the reservoir R of scooped liquid. The valve 29 has a bevelled edge 33 which seats on a bevelled seating 34 in the cover plate 35. It may be replaced by a valve as described in connection with Fig. 4 of Specification 493,703. The gearing in the gear box 10 may be of the kind described in Specification, 486,589.

Title: Propelling pencils
Inventor: FRICK WERNER
IPC: B43K29/06
Filed: 1949-09-16
Abstract: 679,264. Pencil holders. FRICK, W. Sept. 16, 1949, No, 23892/49. Class 146 (iii). A propelling pencil is combined with a lead sharpener, such that by alternate depression and release of a spring-loaded push button at the rear end of the pencil the lead is sharpened by the sharpener which is in the form of a grinding attachment provided in the front end of the pencil casing. The pencil casing comprises sleeves 1, 1<SP>1</SP>, in which a lining tube 4, 4<SP>1</SP>, is secured by screws 5, 6 and 7. A push button 8 carries a lead-guiding tube 9, 9' axially slidable in a ring 11 abutting a collar 12 in the lining tube. The front end of the part 9' of the lead-guiding tube forms a cone 14 which cooperates with a clamping-ring 15 pressed forwards by a spring 17 to clamp a lead 28. Depression of the button 8 causes the ring 15 to abut the tip 2 of the pencil, such that the lead is released to fall under gravity to a projected position. Two grinding jaws 19 forming an angle of about 60 degrees with one another are secured to a plate spring 18 clamped between the lining tube 4 and the pencil casing, while a support 20 projecting between the jaws 19 supports the lead during grinding. During grinding the lead is simultaneously reciprocated axially and rotated by depression and release of the button 8 which carries pins 23, 23<SP>1</SP> engaging suitable helical cam slots such as 21, 21<SP>1</SP> in the tube 4 for this purpose. The button 8 may be retained in a forward position, such that the lead is held projected for writing by reason of the pins 23, 23<SP>1</SP> engaging slots 27 laterally offset from longitudinal slots 24. In a modification, a cam sleeve having a curved slot, is loosely mounted on the lead grinding tube while being engaged by a guide screw secured to the pencil casing, such that rotation of the sleeve caused by axial movement of the push button is transmitted to the grinding tube through teeth on the rear ends of the sleeve which engage similar teeth on a ring secured to the grinding tube.

Title: Improvements in or relating to electron discharge tubes
IPC: H01J43/02
Filed: 1936-09-02
Abstract: 480,867. Discharge apparatus; thermionic valve circuits. FERRANTI, Ltd., and TAYLOR, M. K. Sept. 2, 1936, No. 23976. [Classes 39 (i) and 40 (v)] An electron - discharge tube comprises a cathode a, which may be thermionic or photoelectric, a control electrode b, a secondaryemitting electrode g and an anode e, each of the two latter electrodes being formed in two or more elements, which are arranged alternately and on the surface of a cylinder of circular cross-section. The elements of the electrodes g and e are respectively connected together by leads h, f and an annular permanent magnet or a magnetic coil k surrounds the tube. The electrons emitted from the cathode are constrained to follow two fan-shaped paths between the control grid support wires c, and impinge on the elements g, whereby secondary electrons are liberated which are collected by the anode elements e. A screen grid d may be provided and the electrodes e, g may take the form of coatings on the glass envelope of the tube. Additional small plate-like or wire electrodes at a small negative potential may be provided between the screen grid d and the electrodes g, e along the line joining the rods c, c which serve also to concentrate the electrons into beams, and the electrode g may be provided with heat radiating fins or a blackened surface. The tube may be used as a mixer in a superheterodyne receiver, by connecting a tuned input circuit to the control grid and a second tuned circuit to the electrode g, this latter circuit being self-oscillating and providing the local oscillation; a beat frequency is thus generated in the anode circuit. When used as an amplifier operating uniformly over a large range of frequencies, the secondary emissive electrode is used as the output electrode, the mutual conductance of the valve with respect to this electrode being negative, whereby feed-back through the valve capacity increases the input signal. By varying the magnetic field, the valve may be used for modulation or gain control. In the latter case, as applied to an A.V.C. circuit, the magnetic field is varied at the same time as the control electrode potential changes and in such a direction as to maintain the anode current unaltered in value.

Abstract: 741,808. Bolt action rifles. BIRMINGHAM SMALL ARMS CO., Ltd. July 17, 1953 [April 17, 1952], No. 24187/51. Class 119 A slot 13 Fig. 2 in the forward end of the bolt 1 of a bolt action rifle is engaged by a. projection 21 on a sear 17 urged upwardly by a spring-loaded lever 29 when the bolt is at its normal limit of rearward movement, disengagement of the bolt and sear to allow further rearward movement and direct removal of the bolt from the rifle being effected by pulling and holding the trigger, thus operating a spring-loaded catch 25 which passes through a slot 33 Fig. 3 in the lever 29 and by virtue of an inclined face 28, the lever 29 on being depressed by the sear 17 by slight forward movement of the bolt, is held by the catch 25 in the depressed position, thereby permitting the sear 17 to remain clear of the bolt which can then be withdrawn. The shape of the slot 13 is such that forward movement of the bolt is not impeded. Fig. 1 shows the cocked position of the trigger mechanism in which sear 17 is held in engagement with the cocking piece 5 by a stop 27 on the lever 29 contacting the catch 25. On pulling the trigger, the catch 25 is released from the stop 27, passes through the slot 33 thus permitting the sear 17 to be depressed to release the firing pin 3 under the action of the spring 7.

Filed: 1953-09-01
Abstract: 746,602. Electric control systems. OWENSCORNING FIBERGLAS CORPORATION. Sept. 1, 1953, No. 24192/53. Class 40(1) [Also in Group XVIII] In an apparatus for indicating and controlling the level of molten glass 11 in a tank 15, a pivotally-mounted, hollow probe 12 is cyclically advanced towards and withdrawn from the surface of the glass whilst directing a stream cf air on to the surface by a reversible motor M which drives a rack 22 connected to the probe by links 21, 18 and a lever 19, the increase in pressure in the probe due to the resistriction in air flow as its tip nears the surface causing a diaphragm control 30 to close contacts 43 energizing a relay 45, Fig. 5. The relay 45 closes contacts 45a, 45b, the latter energizing a time-delay relay 47 and a relay 50. Relay 50 opens contacts 50b to stop motor M so that the probe is halted at a position corresponding to the glass level. The relay simultaneously closes contacts 50a to energize a relay 53, the latter opening contacts 53a thus de-energizing a relay 57 which operates to release a brake on a recording pen 56, the relay 53 also closing contacts 53b to supply current to a series resonant bridge recording circuit shown at 58. The recording circuit is used in co-operation with transmitting coils 25 in which an armature 24 attached to rack 22 is vertically movable. If the probe is at a different level from that recorded in the preceding cycle, a receiving armature linked with the recording pen and movable within receiving coils is moved to the matching position within the coils by the current flow in the resonant circuit, the movement continuing until balanced current conditions are restored, the pen registering the new level on suitably calibrated paper. The recording operation takes place during the period of the time delay of relay 47. At the end of this period the relay opens contacts 47a to de-energize relay 53 thus locking the pen brake and de-energizing the recording circuit. It also closes contacts 47b to start the motor M in the reverse direction, the probe being lifted until a finger 31 on rack 22 actuates a limit switch 32. This switch opens contacts 60 to de-energize relay 45, contacts 45b are thus opened to deenergize relays 47 and 50, the opening of contacts 47b and closing of contacts 50b again reversing the direction of the motor so that the probe descends and the. cycle is repeated. As shown in Fig. 6, the level of the glass in the tank is controlled by causing the receiving armature to actuate a pressure controller 70 to supply air at a pressure determined by the recorded probe position to a piston air operator 72, the operator adjusting a variable speed duevice 73 which controls the speed of a feed screw 75 so that batch material is fed into' the tank at a rate inversely proportional to the glass level therein.
