Patent GB-951859-A (GB)
Title: A high-pressure vapour discharge lamp
IPC: H01J61/18
Filed: 1962-06-01
Abstract: 951,859. Discharge lamps. PATENT-TREUHAND-GESELLSCHAFT FUR ELEKTRISCHE GLUHLAMPEN. June 1, 1962 [June 2, 1961], No. 21197/62. Heading H1D. A high-pressure vapour discharge lamp giving an emission similar to natural light and a high light yield has an envelope 7 of high melting-point material, e.g. quartz or alumina, and the energized filling comprises one or more rare earth halides, e.g. lanthanum or cerium chloride or bromide which are transparent and colourless in the molten state. Additionally, a rare gas, mercury, and excess halide may be present. The material to be energized forms a molten film 11 on the surface of the envelope 7 and the core, which may fill the tube or be urged against the film 11 by a weak magnetic field, may locally over-heat the material so as to produce a " vapour pressure " of material in the discharge substantially greater than that corresponding to the maximum wall temperature, the condensed material returning to the evaporating zone 11 by gravity or capillary flow. The lamp may be air or water cooled. Starting may be by external heating, a high voltage impulse, or by the rare gas filling.

Title: Timing of fuel injection pumps
Inventor: CHALLIS KENNETH ERNEST
IPC: F02M59/20
Filed: 1956-07-09
Abstract: 825,136. Fuel injection pumps. NAPIER & SON Ltd., D. June 25, 1957 [July 9, 1956], No. 21257/56. Class 102(1). In a fuel injection pump of the "spill" type having the usual control surfaces on the plunger to determine the beginning and end of the injection period the timing of injection is varied by altering the rear position of the stroke of the plunger in relation to the pump chamber. The pump plunger 1 is secured at its lower end to a piston 6 which slides in a cylinder 7 of the tappet 8 carrying the cam follower roller 16. The piston 6 has a boss 11 at its lower end and is urged downward by spring 15 while its upward movement is limited by a retaining ring 9. Liquid is fed through port 18 to an annular passage 17 in the pump body and the tappet 8 is provided with a series of ports 14 which align with the passage 17 when the tappet 8 is at its bottom dead centre position so that the liquid from the port 8 and passageway 17 flows into the cylinder 7 and raises the piston 6 when the pressure is sufficient to overcome the action of the spring 15. This movement of the piston 6 raises the rear position of the stroke of the plunger 1 and consequently advances the timing of the injection. On reducing the pressure applied to port 18 the timing is retarded.

Title: Improvements in and relating to vapour separation and condensation particularly for use with oils
IPC: C10G7/00
Filed: 1925-08-25
Abstract: 239,208. Power Specialty Co., (Assignees of Bell, J. E.). Aug. 27, 1924, [Convention date]. Rectifiers; separate heater and evaporator apparatus. - In fractionally condensing oil vapours, the mixture of oil and vapours from an oil heater is discharged through a tangential inlet B above a conical baffle C into a vapour separator A. Oil collects in the base and the vapours rise through traffles D and are passed through successively cooler condensers A<1>, A<2>, A<3>. The oil collecting in the base of each of the vessels is passed through coils immersed in the liquid in the base of the succeeding vessels where it serves as heating agent, and is afterwards passed through coolers J, and part of it is returned by pumps M, M<2>, M<3> to serve as reflux liquid in the preceding vessel. The vapours from the last condenser A<3> pass by a pipe F<3> to a cooling coil S having an outlet S<1> for permanent gases, an outlet S<2> for condensate, and a connection O<3> for returning some of the condensate as reflux to the condenser A<3>.

Title: Improvements in and relating to hoisting or lowering apparatus
IPC: B66B17/26
Filed: 1935-07-27
Abstract: 462,292. Guiding skip hoists ; loading skips ; delivering material from hoppers. BIRTLEY CO., Ltd. (Roberts & Schaefer Co.) July 27, 1935, No. 21405. [Classes 78 (i), 78 (iii), and 78 (iv)] In skip-winding apparatus having hinged skip loading and discharge gates 10, 2, Fig. 8, automatically operated by the movement of the skip 1 and locked during travel of the skip by latches 14, 3 released by the skip at appropriate parts of its travel, means are provided for removing the pressure of the gates from the latches prior to the release of the latter and for causing the gates to open in a controlled manner, the said means being constituted by the gates or members attached thereto and suitably shaped coacting surfaces on the receptacle into which the material is to be discharged. The skip is loaded at the bottom of a mine shaft from a shoot 19 normally closed by the gate 10, locked by a pivoted catch 14, Fig. 5, engaging teeth 18 on the gate. As the skip approaches the loading position a roller 12 on the gate 10 engages the vertical part of a 1 -shaped guide 11 on the skip so that the gate is pressed inwards to release the pressure on the catch 14. Whilst the pressure is thus released a guide 13 on the skip engages a roller 15 and raises the catch 14 clear of the teeth 18. Further downward movement of the skip causes the roller 12 to travel along the horizontal part of the guide 11 and thus allow the gate 10 to open gradually as the skip reaches its lowest position. When the skip is raised the roller 12 moves back along the guide 11 and closes the gate, and the guide 13 engages the roller 15 to lift and then drop the catch 14 while the guide 11 holds the gate closed. At the top of the hoist the skip gate 2 is similarly opened and closed, a roller 6 on the gate engaging a fixed 1-shaped guide 5, Fig. 1, and the locking catch 3 having a roller 9 engaging a fixed guide 7 for releasing and engaging the catch. The gates 2, 10 are similar and each is pivoted on a hollow shaft 22, Fig. 10. The bottom plate 32 of the gate carries a plate 30 which rests on the fixed hollow shaft 22 so that when the gate rotates on the shaft the plate scrapes against the shaft and prevents spillage of coal. The gate catches 8 or 14 are fixed to the side plates of the gate and are formed with two teeth 33, 34 so that as wear takes place the pivoted catch 3 or 14 will always engage a tooth. The front plate 37 of the skip, Fig. 9, has an opening which is high at the centre and low at each side to allow free delivery of coal at the centre as the gate 2 opens and to restrict the flow at the sides and avoid spilling.

Abstract: 832,776. Hydraulic transmissions. PAYNE, R. Oct. 10, 1957 [July 11, 19561, No. 21462/56. Class 69 (2). An hydraulic transmission for vehicles comprises a rotary abutment pump having several sections selectively connectible to a rotary abutment motor to give a plurality of gear ratios. A pump 1 comprises parts A, B, C, each of which has a vaned rotor 24 splined to a common sleeve 25 driven through epicyclic reduction gearing from an input shaft 26. Each rotor co-operates with two rotary abutments 30 which are geared to the sleeve 25 so that the pump has six sections, each section having an inlet channel 43 leading from a common chamber 48, and a discharge channel 44 from which liquid can discharge either through a non-return valve 44<SP>1</SP> to a common chamber 49 or to a by-pass chamber 50 through a valve 52 operable by a cam 55 on a common cam-shaft 56. Chambers 48, 49 are connected through a reversing valve 57 to lines 3, 4 connected to a motor 5. Two motors may be provided, each connected to an output shaft to form an hydraulic differential, or one motor may be provided, in which case it can be formed with the pump as a self-contained assembly. A valve 24<SP>1</SP> is provided for bypassing the motor to allow free wheeling. A shock absorbing device 70 is connected between the lines 3, 4, and the lines are also connected, through a change-over valve 68 to a tank 59 to supply replenishing liquid and maintain a minimum pressure in the lowpressure line. The air space of the tank is connected to the induction manifold of the engine to maintain a degree of vacuum to prevent aeration. For cooling, part of the liquid in the return line may be passed through a radiator the inlet and outlet of which are both connected through change-over valves to the lines 3, 4. To increase the number of gear ratios available the pump sections may have different capacities. In a modification a pump is provided which has five ports, each part comprising a rotor co-operating with a single rotary abutment.
