Title: Improvements relating to apparatus for tempering tubular glass articles
IPC: C03B27/06
Filed: 1934-12-04
Abstract: 448,266. Tempering glass. PILKING- TON BROS., Ltd., 703, Tower Building, Water Street, Liverpool, and CLITHEROW, W. B., 44, Kiln Lane, St. Helens, Lancashire. Dec. 4, 1934, No. 34878. [Class 56] Apparatus for tempering tubular articles of glass, such as miners' lamp glasses, comprises a heating furnace and an external blowing frame, the articles being threaded on a metal tube which is provided with supporting and spacing pins and is perforated with holes from which jets of air are directed on to the articles. The metal tube 1, Fig. 1, is closed at its lower end 5 and is connected at its upper end by a flexible pipe 7 with a source of air under pressure. The glass articles 3 are supported on horizontal pins 2 which are passed through holes in the tube 1, and fixed pins 4 serve to keep the articles coaxial with the tube 1. Holes 6 are formed in the tube 1 to direct jets of air against the inner walls of the articles 3. The heating furnace consists of a tube 8, Fig. 3, of refractory material with an electrically heated spiral 9. A blowing frame, arranged above the furnace, consists of two annular headers 11 joined by tubes 12 which are provided with air holes. In operation, the tube 1 loaded with glass articles is lowered into the furnace, and when the glass articles are sufficiently heated, they are raised into the frame and chilled by air blown simultaneously into the tube 1 and into the frame 11, 12. Alternatively, the furnace and the blowing frame may be moved while the tube 1 remains stationary. In a modification, the blowing-frame may be constructed to receive a number of the tubes 1, and heating may be effected in a furnace used in tempering glass plates.

Title: Method and apparatus for determining the exposure of a recording material
Inventor: STAES K
IPC: G03B27/73
Filed: 1968-07-22
Abstract: 1,271,505. Photographic exposure control. AGFA-GEVAERT. July 14, 1969 [July 22, 1968], No.34896/68. Heading G2A. The luminance of a subject is measured in at least two spectral regions and exposure is either made solely on the basis of the largest measured luminance or is made by taking the largest luminance into account more than the other luminance(s). The process may be used in determining exposure in still and cine cameras, photographic printers, photo-copiers and electro-photographic copiers. The luminances may be measured using the same exposure meter with three different filters in turn and multiplying the readings by correction factors. Alternatively, a preferred arrangement for cine cameras which is shown in Figs.5, 6 comprises a shutter which reflects light on to photo-cells 18, 19, 20 via beam-splitters 13, 14 and filters 15, 16, 17. A circuit (comprising amplifiers 25, 26, 27, 31, diodes 28, 29, 30 and resistors 32, 33, 34) compares the signals from photo-cells 18, 19, 20 and produces a reading at a galvanometer 35, the reading depending solely on the signal from that photo-cell receiving the most light. This reading may be used for manual or automatic exposure control. By modifying the inputs of amplifiers 25, 26, 27 the signals from the other photo-cells can also be taken into account. The photo-cells may be photo-voltaic (e.g. selenium cells or silicon diodes), photo-resistive (e.g. CdS), photo-transistors or photo-multipliers.

Abstract: 1306040 Determining co-ordinates of a curve electrically INSTRONICS Ltd 27 July 1971 [27 July 1970] 35298/71 Heading G1N Apparatus for determining the co-ordinates of the points on a curve on a sheet of paper comprises means for fixing the sheet under a rectangular frame 25, Fig.2, carrying perpendicular wires 41, 43 attached over pulleys 81, 83, 87, 89 to cables 49, 69, and a pick-up coil 27, Fig.6, which is manually made to follow the curve. The wires 41, 43 are fed with 90 degrees dispaced voltages from an oscillator 105 and the signals picked up by coil 27, after phase detection, represents the displacements between coil 27 and each of the wires 41, 43. These signals are fed to servomotors 101, 103 which move the wires 41, 43 individually until their cross-over point is directly under coil 27 and therefore coincides with a point on the curve. The X and Y coordinates of this point are sensed by encoders 131, 133 also driven by motors 101, 103 and recorded when a foot lever is operated. In a modification, the functions of coil 27 and wires 41, 43 are reversed, i.e. coil 27 is fed with A.C. and the signals picked up by wires 41, 43 are used to energize the servomotors.

Title: Rechargeable cell with cadmium anode
IPC: H01M4/26
Filed: 1973-07-25
Abstract: 1383282 Cadmium anode for secondary cell GENERAL ELECTRIC CO 25 July 1973. [25 July 1972] 35435/73 Heading H1B The anode comprises a mixture of cadmium metal particles having an average particle size of 3-12 microns and cadmium oxide powder in a binder and applied to a foraminous substrate. The amount of cadmium oxide determines the capacity of the anode and this is made at least equal to and is preferably greater than, the capacity of the cathode The cadmium metal acts as a precharge and provides a reserve capacity to compensate for deterioration of the cadmium oxide which may occur in use. Preferably, the amount of precharge cadmium is 33 % of the combined weight of the cadmium and cadmium oxide. To prevent premature oxidation of the cadmium metal particles before they are mixed with the cadmium oxide powder they are stabilized with about 1 % by weight cadmium oxide. This may be performed by producing spherical cadmium particles by condensing vaporized cadmium metal in an atmosphere of a controlled amount of oxygen. The binder is preferably PTFE and is added to the Cd-CdO powder mixture in an aqueous dispersion, the resultant slurry being heated to 170 F. to form a paste which is applied to a nickel wire mesh substrate. The composite is pressed and dried at 110 F. to form the electrode. The binder is present in amount of 1 % by weight of the Cd- CdO mixture. Nickel powder of an amount 1 % by weight may also be added to the mixture. The cadmium electrode may be wound with a nickel cathode to form a coiled cell operating with a KOH electrolyte.

Title: Improvements in or relating to hydrostatic steering systems, particularly for motor vehicles
IPC: B62D5/09
Filed: 1967-08-02
Abstract: 1,146,797. Power-assisted telemotor steering systems. ZAHNRADFABRIK FRIEDRICHSHAFEN A.G. 2 Aug., 1967 [3 Aug., 1966], No. 35449/67. Heading B7H. In a hydrostatic or telemotor steering system comprising a twin-output control pump 3 driven by a steering-wheel 1 and acting as a proportioning means, and a device which includes a pair of control valves 4, 5 and is operated in dependence on the movements of the steering wheel to control the direction of fluid flow from a servo-pump 8, two hydraulic circuits are supplied by the control pump 3 and each circuit comprises the two control valves and a servomotor 6, 7. As shown, each circuit is controlled by one-half of the control pump 3 and by both control valves 4, 5. On rotating the steering-wheel 1 clockwise firstly the ring gear of the epicyclic gear train 2 moves the valve spools 40, 50 of the valves 4, 5 to the right and left to determine the direction of fluid flow and secondly the sun-wheel of the gear train 2 rotates the control pump 3 which accepts from lines 13, 18 high-pressure fluid which is supplied from the servo-pump 8 through grooves 41<SP>1</SP> and 42 and through a groove 51<SP>1</SP>, bore 55<SP>1</SP> in the valve spool 50<SP>1</SP> and grooves 54<SP>1</SP>, 54 and directs it to the servomotors 7 and 6, respectively, through a line 17, grooves 52, 52<SP>1</SP> and a line 19 and through a line 14, grooves 44 and 43<SP>1</SP> and a line 16. Exhaust fluid from the servomotors is returned to a reservoir 9 through the control valves 4, 5 and lines 12. Should one of the lines 15, 16, 19, 20 break a respective valve may be operated manually to return the fluid being supplied to the broken line to a line 12 and the reservoir 9. Due to the reduction in pressure at the respective outlet of the control pump 3 the pump tends to act as a motor thereby indicating the breakage to a driver. In the neutral position of the steering wheel the control pump 3 blocks communication between the control valves 4, 5 holding the servomotors stationary. A valve 10 permits operation of the steering system manually should the pump 8 be inoperative.

Abstract: 346,797. Cylinders. FRASER, R. P., 20, Margravine Gardens, Baron's Court, London. Nov. 20, 1929, No. 35517. [Class. 7 (ii).] The combustion space of an internal-combustion engine is formed so that at the instant of ignition or when the piston is at top dead centre flame and pressure effects resulting from the explosion proceed along two endless paths. In the side-by-side valve engine shown in Fig. 10 the two paths are formed by a bridge-piece 7 extending horizontally across the chamber 4. The bridge-piece may be hollow to facilitate cooling. A sparking plug 5 is located in either of the two positions shown and the wall 8 between the valves is of volute form so that the inlet and exhaust gases shall flow freely past the valve seats. In a modified construction the bridge-piece depends from the head of the combustion chamber. In an overhead valve engine (Fig. 14) the valves 2, 3 are located on an internal projection 6. An annular space 4 with chamfered edges 9 contains the igniter 5 and serves as the combustion space. Other shapes of combustion chambers are described applied to engines having various arrangements of valves.
