Abstract: 694,372. Jet propulsion plant; stuffing box packing. ARMSTRONG SIDDELEY MOTORS, Ltd. July 16, 1951 [Sept 8, 1950], No. 22155/50. Classes 110(iii) and 122(v) [Also in Group XXIX] A combined stop and throttle valve for the control of the supply of a liquid fuel or oxidizer from a pump to the combustion chamber of a rocket motor, has, at its outlet, a throttle member with a passage through it to allow a predetermined delivery when it is in the closed position, which is biased to the closed position, and in series therewith and connected to the pump discharge, a stop valve member which is also biased to the closed position. The combined valve shown comprises a throttle member having a pear-shaped hollow head 12 which is forced on to its seating 13 by a spring 16 acting on a plunger 15. Fluid pressure applied through an inlet 17 is used to open the throttle member. In the closed position shown liquid oxidizer can pass through a hole 18 into the interior of the head 12 and out through holes 19 to the combustion chamber. The holes 18, 19 may be dimensioned to give a flow of about one-third of that given when the throttle member is fully open. The stop valve member which is connected to the inlet 24 of the combined valve is of a construction similar to that of the throttle valve member except that the holes 19 are omitted. The stop valve is opened by fluid pressure applied through an inlet 25. Annular abutments 34 limit the opening of both the stop and throttle valve members. The stem of each valve member has a parallel portion 36 operating in a gland (not shown) comprising a triangular leather ring impregnated with bees wax which is pressed against a frustoconical seating by a spring loaded ring. The sealing ring may also be made of a thermoplastic e.g. polytetra-fluoroethylene or synthetic rubber. Two other valves 43, 50 may be incorporated in the structure at the pump discharge end 24. Valve 43 is spring biased to the closed position and is opened by fluid pressure applied at the inlet 45. This valve may be used when it is required to supply a small amount of oxidizer to igniter equipment in the combustion chamber. The valve 50 is biased to the open position and controls a port 52 leading back to the oxidizer reservoir. This valve may be closed by fluid pressure applied at the inlet 55. A modified form of combined valve may be used to control the output of the fuel pump. The fuel may be a mixture of methyl alcohol and water and the oxidizer liquid oxygen or nitric acid. Specifications 681,498 and 694,371 are referred to.

Patent GB-694325-A (GB)
Title: Improvements in stock feeding mechanism for automatic lathes and screw machines
IPC: B23B13/00
Filed: 1950-09-11
Abstract: 694,325. Automatic turret lathes. CONE AUTOMATIC MACHINE CO., Inc. Sept. 11, 1950 [Sept. 10, 1949], No. 22326/50. Class 83 (iii). A stock - feeding means for automatic lathes comprises a hollow spindle through which stock is fed, a stock clamp carried by the spindle, a reciprocating stock pusher, yielding means for actuating said pusher to feed stock when the stock clamp is released, and indicating means responsive to motion of the pusher in stock-feeding direction when said clamp is in stock-gripping condition and said stock has been exhausted. As applied to a multi-spindle turret lathe with collet clamping - mechanism as described in Specification 456,284, the reciprocating- gripper tube 16 has a flange 20 at its rear end which is engaged at one station by a groove 21, Fig. 3, in a roller 22 carried by a blook 30. This block has a swivel head 56 through which slides a link 55 carrying stopnuts 59, 59a which, through a lever 53 and cam drum 38 on the main cam-shaft 7, reciprocates the gripper in timed relation to the opening and closing of the bar clamping-means. The block 30 is connected to a tube 32, Fig. 4, inside which a spring 35, compressed between the end 350 of the tube and a stop on the end of an anchor bolt 33, tends to move the tube 32 to the right as shown. When the gripper has been moved back by the cam face 40, providing there is a length of bar stock within the spindle, the follower 53 does not move into the depression 41 in the cam drum 38. If, however, the end of the stock has passed beyond the gripper the follower 53 moves into the depression 41 and a cam-piece 61 on the hub of lever 53 opens a switch 47 in the main motor circuit 45, 46. In such position this corresponds to the opening of a switch 48 operated by the cam-shaft 7. Opening of both switches together stops the main driving motor M and may, through a relay, act to energize a light or bell as a further warning of an " out-of-stock " condition of the machine.

Title: Improved means for automatically regulating the load in electric circuits
IPC: G01R35/04
Filed: 1939-08-02
Abstract: 528,841. Automatic contol systems. ALMOND, J. August 2, 1939, No. 22452. [Class 38 (iv)] [Also in Group XL] Current. A step-by-step regulator of the load in an electric circuit is controlled to operate in alternative directions by a photo-electric system sensitive to load fluctuations. Excessive fluctuation increases the speed of operation. A torsion head galvanometer 1 under desired load conditions reflects a beam of light equally on to photo-cells A, A1 whereby a relay X is currentless. A change in load causes contact to occur at X1 or X2 whereby a solenoid 191 or 192 is energized to permit one of two oppositely acting pawls to engage a toothed wheel. The pawls are continually oscillated by a motor 15 so that the wheel effects a step-by-step restoration of the load to the desired condition. Excessive fluctuation unbalances a second pair of photocells B, B1 whereby a relay Y selectively energizes relays N1, N2 which (1) energize relay Ml, M2, (2) sound an alarm 22 and (3) remove a short circuit from a resistance in the field circuit of the motor 15. The system is arranged to effect a step of adjustment within the period of a halfswing of the galvanometer. Sensitivity may be varied by shielding or altering the power of the lamp, by adjusting the contact distances in the relay X or by shuttering the photo-cells. The cells may be shielded from external light and covered by a slatted screen of white celluloid to render the beam position visible.
Patent GB-993276-A (GB)
Title: Improvements in or relating to tape-feeding apparatus
IPC: G11B15/58
Filed: 1962-06-12
Abstract: 993,276. Feeding webs. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 12, 1962 [June 26, 1961], No. 22503/62. Heading B6B. [Also in Division G5] In a vacuum column which has a source of vacuum connected to the closed end of the column opposite the open end, record tape enters and leaves, forming a loop across the column between the sides to divide a region of lower pressure from a region of atmospheric pressure. As a tape 10 enters a column 23, Fig. 3, air is drawn into the zone 28 between the entry side 25 of the column and the tape 10. A pressure above atmospheric is prevented from increasing by allowing the air to escape through holes 51 in the side 25 of the column. As the tape leaves the column, air is drawn out of the zone 27 between the exit side 26 of the column and the tape 10. The tape is prevented from clinging to the side of the column, causing unnecessary wear, by providing holes 41 open to atmosphere. As shown in Fig. 2, the holes 41 and 51 are associated with horizontal and vertical grooves on the inside surfaces of the sides 26 and 25 providing an even distribution of air. Air is allowed to leak into lower pressure region through certain holes 51 when the tape is in the upper position shown in Fig. 3. This leakage is prevented in a modification, Fig. 6, wherein the holes 51<SP>1</SP> are connected by tubes 52<SP>1</SP> to holes 61 passing through the front or back of the column into the interior of the column. When the tape travels in the opposite direction to that of Fig. 3, it is in a lower position, as shown in Fig. 6, and air from atmosphere is allowed to enter the zone 28 via tubes 52<SP>1</SP>. When the type is in the upper position, leakage of air is prevented as the holes 61 are in the lower pressure region. Specification 733,807 is referred to.

Abstract: 1426808 Treating exhaust gases NISSAN MOTOR CO LTD 11 May 1973 [16 May 1972 27 May 1972 5 Sept 1972] 22645/73 Heading B1W [Also in Divisions F1, F3 and F4] An I.C. engine is combined with a source 54, 82 of hydrogen peroxide, manganese dioxide or dimanganese trioxide, an exhaust system with a thermal reactor for oxidising unburnt or partially burnt exhaust gas constituents and means to supply the oxygen compound from the source or decomposition products of the oxygen compound to the engine or the exhaust system 16, 72 to facilitate oxidation of one or more constituents of the exhaust gas. In Fig. 1, hydrogen peroxide is supplied to a float chamber 60 by pump 56 and thence to venturi 26 of carburettor 24. Manganese dioxide or dimanganese trioxide may be used in suspension or injected in powder form. In Fig. 2, hydrogen peroxide is fed from source 82 to a decomposer 84 containing catalyst (96) Fig. 3 (not shown) or a glow plug (98) Fig. 4 (not shown), the resultant oxygen passing to an exhaust reactor 74, the products from there being exhausted via a premuffler 78 and a main muffler 80. The rate of supply of peroxide is controlled by a metering valve 88 in response to engine load and/or speed. Water vapour collected in condenser 100 is returned to the intake manifold via carburettor 70. The exhaust gas may be treated by injecting hydrogen peroxide to a point between the exhaust valve (104) and the reactor (74) by means of a nozzle (108) Fig. 5 (not shown).  In a rotary piston engine Fig. 6, hydrogen peroxide is supplied from a source 132 via valve 136 to an injection port 144. It is timed in relation to the power phase of each working chamber. The port 144 may be disposed in the epitroohoidal surface at a location forward of the exhaust port of exhaust channel 112 in the rotational direction of rotor 116 and in this case the hydrogen peroxide injection is preferably timed in relation to the exhaust phase of each working chamber, but continuous injection of hydrogen peroxide is possible.

Title: Improvements relating to work-feeding means in machine tools
IPC: B23Q3/16
Filed: 1957-07-18
Abstract: 880,186. Drilling. RYE ENGINEERING WORKS (HIGH WYCOMBE) Ltd., EVANS, E. F., EVANS, J., and EVANS, W. C., [Representatives of EVANS, F. H.]. Oct. 15, 1958 [July 18, 1957], No. 22828/57. Class 83 (3). [Also in Group XXIII] A machine for performing operations such as sawing, drilling, slotting or tenoning on furniture parts or other workpieces comprises a chain conveyer 31 having dogs 32 which move the workpieces to a position close to withdrawable stops 43 at one or more operating stations and pusher means 48 which complete the movement of the workpiece up to the stop at the or each station. A pair of sub-assemblies 12, 13 are adjustable toward and away from each other to suit the length of workpiece and each sub-assembly carries one of the conveyer chains between rails 33, a circular saw 16 and a multiple spindle drilling head 18. Universal pivoting adjustments are provided for the saw and drilling head and the latter is also adjustable vertically. A pneumatic cylinder feeds the saw downwards and another cylinder feeds the drills horizontally. The stops 43 and the pushers 48 are carried on the inner rails 33 and are each raised against a spring by a pneumatic cylinder 45 or 50 coupled to a common supply line having a valve 52 which ensures that the stops are raised before the pushers operate. A motor 58 drives, through a reduction gear, a cam 59 controlling the sequence of operation of the machine and a crank-pin 61 connected to a pawl 65 which normally imparts intermittent rotation to a ratchet wheel 66 on a driving shaft 39 but can be withdrawn to stop the feed by a pneumatic cylinder 67 controlled by a stop-start lever. Each time a workpiece is moved into position near a stop, a lift 85 on the cam 59 trips an air valve 70 and the stops and pushers are operated. An adjustable trip 72 on the cam then operates a valve 74 and causes the saws to be lowered and the drills fed in. As the drills are fed in, a valve is operated to lower clamps on to the workpieces and when the operations on the workpieces are completed an adjustable trip 73 operates a valve 80 which causes the saws and drills to return to initial position. When the drills are nearly fully retracted, the clamp valve is again operated to release the clamps and the fall 86 of the cam 59 then operates the valve 70 to allow the stops and pushers to be retracted by their springs. An air-pressure cut-out switch may be provided to cut-out the supply to the electric motors if the air pressure falls and an additional valve may be provided to control semi-permanent disengagement of the pawl 65 by the cylinder 67. Mechanical, solenoid or hydraulic operation may be used in place of some or all of the pneumatic cylinders. The Provisional Specification refers to the tenoning head described in Specification 712,446.
