Title: A Sighting and Range-Finding System, for Instance for an Armoured Vehicle
IPC: G01C3/00
Filed: 1965-03-05
Abstract: 1,181,061. Optical ranging. ERNST LEITZ G.m.b.H. 5 March, 1965 [20 April, 1964], No. 9572/65. Heading H4D. A sighting and range-finding system, e.g. for an armoured vehicle, comprises a vertically and laterally adjustable television camera 3, a sighting mark 22 placed to provide an image thereof in the camera proportional in size to a target, a zoom lens 14 placed to provide an image of the target in the camera and adjustable for making the two images coincide at least in one dimension, and a receiver 11 for reproducing the images. The sighting mark has a one- or two-dimensional extent, e.g. two parallel lines spaced apart a given distance, a box-like rectangular outline, or the outline of an armoured vehicle, and may be etched on a glass plate. The range is determined in accordance with the change in magnification required to produce the coincidence of the two images. In order that the system may be adapted to targets of different sizes, the sighting mark is replaceable, or is such that its extent can be varied by adjusting the spacing of two spaced marks which constitute the sighting mark. The mark is preferably arranged in an intermediate image plane of the camera lens. It is also possible to reflect the sighting mark into the camera, Fig. 3 (not shown). Adjustment of the camera can be by remote control, for example by Bowden wire, from the observation point. Electric motors M are preferably used as the adjusting means. In order that the observer carrying out the sighting may simultaneously observe other areas on the horizon, additional television cameras may be provided, coupled with the receiver or with additional receivers connected in series with, or arranged independently of, the main receiver. One of these cameras, or the camera used for sighting and range-finding, may be fitted with a periscope, Fig. 4 (not shown), which may be focused, optionally automatically, on any area on the horizon by means of a motor-driven adjustment mechanism. Also, any of the cameras may be fitted with a replaceable nightviewing attachment, e.g. an infra-red telescope. In the embodiment described, the leads from the motors for adjusting the vertical and lateral positions of the camera, for adjusting the zoom lens and for focusing the camera lens, together with the leads to a voltage supply source and to the receiver, are accommodated in a common cable 23 passing through an opening in the armour plating of an armoured vehicle. The leads from the motors are connected via a control unit 9 to a computer 24 which feeds data to an associated gun control system of the armoured vehicle.

Title: Improvements in or relating to electromagnetic switches
IPC: H01H9/56
Filed: 1941-07-29
Abstract: 546,582. Electromagnetic switches. IGRANIC ELECTRIC CO., Ltd. July 29, 1941, No. 9635. Convention date, Aug. 1, 1940, [Class 38 (v)] An electromagnetic switch, which may control a welding circuit 2 and is adapted to open and close at predetermined points of an A.C. cycle, has a core 1a, a main winding 1h, a secondary " shading " winding lj embracing a portion only of the flux, and contacts 3b, 3d adapted to short circuit the winding lj and also to connect the winding 1h across the A.C. lines L 1 , L 2 . The winding 1h may form part of a winding 1g which is in series with a resistance 4, variable reactor 5 and variable condenser 6 to form a closed oscillating circuit ; and the armature 1b, 1d may be associated with a holding magnet 1c having main and secondary coils lk, 1l arranged similarly to those on the magnet 1a. In operation, closure of a push-button switch 7 completes at 3d the circuit of operating coil 1h and breaks at 3c the circuit of holding coil 1k. The shading coil 1l is simultaneously open-circuited, and the actual movement of the armature to close contacts 1f will occur when the A.C. in the holding coil is passing through the zero of its cycle and the arc at the contact 3c is therefore broken. To open the contacts 1f, push-button 7 is released whereupon a similar action occurs, coil 1h now, however, holding the armature closed against the influence of gravity &c. till its current passes throuh the zero point. The exact moment for this is delayed for an adjustable time owing to the presence of the oscillatory circuit 1g, 4, 5, 6, the current in which persists after the contacts 3d have opened and .the arc there interrupted. This oscillatory current must therefore pass through the zero of its cycle before the armature is released.

Title: Process and apparatus for the production of sheets of phenolic resin foam
IPC: B29C44/30
Filed: 1972-03-01
Abstract: 1386347 Moulding foamed sheets; laminates DYNAMIT NOBEL AG 1 March 1972 [2 March 1971 2 Dec 1971] 9636/72 Headings B5A and B5N [Also in Divisions C3 and B1] Phenolic resin foamed sheet is continuously produced by forming a premix of a liquid phenolic foamable resin and a blowing agent; mixing the premix with hardener, uniformly distributing the mixture on to a lower cover layer entering a double-belt press and covering with an upper cover layer as it enters the press and heating as it passes through the press to foam and harden. The cover layers may either be stripped off or left on and accordingly they may be coated or impregnated with adhesive or release agent. The sheet produced may be trimmed, cut into lengths and grooved longitudinally and transversely. The density of the sheets produced increases outwardly from the middle. The apparatus comprises storage vessels and metering pumps 6-9 for the various ingredients, the liquid resin being cooled, 11, and passed to a two-stage premixer 12, also cooled, and thence to a mixer 13 which also receives the hardener and additives. This mixer is divided into upper and lower communicating chambers by either a disc on the mixer shaft (Fig. 4, not shown) or an encircling web on the inner wall of the mixing vessel (Fig. 5, not shown), or both forming a labyrinth seal (Fig. 6, not shown). Hardener is supplied to the lower chamber only, so that hardener resin will not come into contact with the bushing by which the shaft is journalled through the vessel housing. The area of the communicating gap between the two compartments is smaller than that of the resin inlet to the upper compartment so that this compartment is pressurized. A nozzle 23 distributes the mixture on to the lower cover layer 42, this having been folded at the edges through 90 degrees to form upstanding sides. The resin is levelled by roller 22 and the upper cover layer applied, the upstanding edges of the lower cover layer then being folded inward over the upper cover layer, by device 24, to form a seal as the layers pass between the lower belt 27 and upper belt 26, the latter being vertically adjustable by hydraulic rams 28. Rubber beading 25 rotates with the belts and is engaged by rails on the belts to form side wall seals. Heating is by a combination of internally placed heating elements and a forced-draught hot air system (Fig. 3, not shown). The cover layers may be taken off by rolls 29 and 30 as the panel emerges through the belts to pass through cutting and grooving devices 32 to 37 to be stacked 38.

Abstract: 722,044. Cycles ; cylinders. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. April 18, 1952 [April 20, 1951], No. 9818/52. Classes 7 (2) and 7 (3). In two-stroke (as shown) and four-stroke engines in which a fuel/air mixture is compressed before ignition, weak fuel/air mixture is fed to a cylinder 1, as through an inlet valve 5 controlling a compressor-fed air conduit 4 supplied with vaporized fuel through a control valve 7, rich fuel/air mixture is formed in a pre-combustion chamber 3, having a volume between 15 per cent. and 35 per cent. of the total clearance volume, by fuel injection thereinto as from a low-pressure diaphragm pump 14 supplied through a control valve 11, and ignition means such as a sparking plug 8 is disposed within the chamber 3. The fuel content of the weak mixture at full load is less than 80 per cent. of that of a stoichiometric mixture ; injection into the chamber 3, which occurs within the first half of the compression stroke, provides a substantially stoichiometric mixture therein, between 15 per cent. and 35 per cent. of the total fuel consumed at full load being used in forming the rich mixture. Fuel control at partial loads is effected mainly or wholly by the valve 7, with or without air control by a throttle valve in the conduit 4. In Fig. 2 (not shown) exhaust ports 13 are replaced by a cylinder head exhaust valve and crankcase compression of the weak mixture is employed, injection into the chamber 3 occurring as soon as piston-controlled transfer ports in the cylinder 1 are closed.

Title: Method of disturbance prevention in high frequency electrical transmission systems and means therefor
IPC: H04B3/32
Filed: 1931-04-01
Abstract: 380,101. Inductances. STANDARD TELEPHONES & CABLES, Ltd., Connaught House, Aldwych, London.-(Lair, J. J. B. and Perroux, G. E. M. ; 46, Avenue de Breteuil, Paris.) April 1, 1931, No. 9864. [Class 37.] A transmission line TL, Fig. 2, coupling apparatus A, B, is given a high impedance to longitudinal currents by coiling the conductors to form an inductance L, a third conductor W being closely associated with the line to form with condenser C an anti-resonant circuit effectively in series in the circuit comprising the two wires of the line. The third conductor may take the form of a metal tube t, Fig. 19, coiled as an inductance and containing the two wires of the line TL, the condenser being connected to the tube extremities; alternatively the tube may form one of the line conductors or two concentric tubes with a central metal conductor may be employed, Figs. 3 and 4 (not shown). In addition to the use of a tubular inductance such as t, Fig. 19, additional series inductances of metal tubular form may be provided wound close together on an earthed former to provide a drain circuit to earth through the capacity between the wires in the tube and the tube itself, Fig. 6 (not shown). An alternative arrangement of a shunt circuit across the transmission line comprises a pair of wires twisted together, short-circuited and earthed at one quarter wavelength at the signal frequency ; the twisted portion may be coiled to form an inductance and the extremity is then earthed through a condenser, Figs. 8 and 9, (not shown). In the latter case the coiled portion and condenser should be screened. An alternative arrangement which dispenses with the necessity of screening is shown in Fig. 10, in which the two wires a, b of the shunt path are coiled into an inductance L with a third wire c. The wires a, b are short-circuited at Q such that the electrical length of PQ is an odd number of quarter wave-leng thsat the signal frequency; all three conductors are short-circuited and earthed at R, the length PR being a whole number of half wavelengths at the longitudinal current frequency. The invention is specially applicable to aerial feed lines in directional wireless and may also provide a method of reception of two transmitted frequencies, simultaneously or otherwise.

Title: Gas-tight lead accumulator
IPC: H01M4/14
Filed: 1966-03-08
Abstract: 1,139,082. Lead accumulators. ROBERT BOSCH G.m.b.H. 8 March, 1966 [9 March, 1965], No. 9992/66. Heading H1B. The invention comprises a gas-tight lead accumulator with plates (3) comprising antimony-free grids and electrochemically active lead paste in contact with a non-liquid electrolyte (8), the major constituent of which is sulphuric acid in which is interspersed a filler containing 0À3% by weight of a calcium or strontium additive. The calcium or strontium additive may be calcium or strontium silicate having a particle size below 30 microns. The electrolyte may be a gel formed from powdered silica and the calcium or strontium additive. It may be at least partly contained in the pores of a separator mat of plastics material or glass fibres, the calcium or strontium additive being adjacent to the negative plates. The plate grids may be of dispersion hardened lead containing a metal oxide and the plates may be formed before insertion in the cell so that the positive ones are fully charged whilst the negative ones contain about 30% of uncharged material. The plates may be flat and parallel as in Fig. 2 or concentric cylinders. A pair of negative plates may be associated with each positive plate, their outer faces being in contact with a corrugated plastics sheet, optionally porous, to provide a gas space where oxygen produced in the cell may be absorbed in the electrode. In this case the amount of liquid in the electrolyte should be less than that required to saturate the filler and the size of the negative plates should be such that their total active mass is not more than 50% more than that of the positive electrode. The cell may include a device which controls the charging current should oxygen be produced during charging, e.g. a pressure switch, or an auxiliary carbon electrode 12 carried under screw plug 11 on which a terminal is mounted. The cell may also include a safety valve, e.g. a bursting membrane.

Abstract: PURPOSE:To reduce thermal noises by supplying charges to a photoelectric converting element and vertical signal line capacity by storage capacity at a vertical scanning frequency as a low frequency, and supplying charges to the storage capacity at a horizontal scanning frequency as a high frequency. CONSTITUTION:Transfer switches composed of MOS transistors(TR) ST1 and SH2 are connected between vertical signal lines 3-1 and 3-2 and horizontal readout switches SH1 and SH2. The transfer switches ST1 and ST2 are turned on at the same time by supplying a transfer pulse 0T in the period from the generation timing of a vertical scanning pulse 0V1 to the generation timing of the horizontal scanning pulse 0H1 and in the period from the generation timing of a vertical scanning pulse 0V2 to the generation timing of the horizontal scanning pulse 0H1. Thus, the charges are supplied to the photoelectric converting element and vertical signal line capacity by the storage capacity at the vertical scanning frequency as the low frequency and then supplied to the storage capacity at the horizontal scanning frequency as the high frequency, so the thermal noises are reduced.
