Title: Method of simulating the voltage increase on load at the zero or neutral point in a three-phase synchronous generator
IPC: G01R31/34
Filed: 1970-11-10
Abstract: 1322040 Three phase supply systems MESSERSCHMITT-BOLKOW-BLOHM GmbH 10 Nov 1970 [27 Nov 1969] 53436/70 Heading H2H A method of simulating the voltage increase on load at the zero or neutral point in a three phase synchronous generator caused by load asymmetry comprises measuring the terminal voltages of the synchronous generator and simulating the voltage increase at the neutral point by performing a vectorial addition of the three terminal voltages using a transformer having an open delta connected secondary winding and converting the vectorial addition into a voltage Uo representing the voltage increase at the neutral point. The generator output terminals k1, k2, k3 are connected to the primary windings of the transformer, the secondary winding of which supplies the voltage Uo<SP>1</SP> to the primary of a second transformer 29. The output voltage Uo of the transformer 29 represents the voltage increase at the neutral point due to the load asymmetry.
Patent GB-1292123-A (GB)
Title: Power locking and unlocking apparatus for vehicle doors
IPC: E05B65/36
Filed: 1969-11-04
Abstract: 1292123 Locks ESSEX INTERNATIONAL Inc 4 Nov 1969 [4 Nov 1968 19 Aug 1969] 54014/69 Heading E2A The latch bolts of vehicle doors are locked and unlocked by reversible electric motors 55, 55a which may be controlled from inside or outside the vehicle and which may be over-ridden by manual control when necessary. This is achieved by inserting into the links 32, 36 connected to the lock-barrel 30 and the sill-button 35, switches 67, 72 which are responsive to tension or compression to activate a control circuit, Fig. 7, which energises all the motors in parallel in the locking or unlocking direction. The latching assembly 4 is of known construction having a rotatable latch-bolt 6 restrained by detent 9 which is disengageable by a lever 10 which may be rocked by the inside handle 15, or by another linkage from a push-button 16 in the outside handle 17 of the front door 2. Each of the four vehicle doors may be unlatched manually from inside by handles 15, 44, or from outside by means of push-buttons 16, 41. The front doors may be locked or unlocked by using a key in locks 30, and all the doors may be locked or unlocked from inside by means of sill-buttons 35, 48. The motorised locking and unlocking function acts on all four doors at once when their energisation is initiated by additional pressure on the front sill-button 35 or the lock 30. The switches 67, 72 which initiate the motor operation are situated in the push-pull rods 36, 32 connected to the sill-bottom and the lock, these rods being interrupted and their end-portions sliding in a guide tube 76, Fig. 6, with lost motion. The electrical switching is accomplished by pads 82, 88 of synthetic rubber filled with metal particles which make mutual contact when the pad is compressed. Compressive force on the rod 65 renders pad 82 conductive, and tension renders pad 88 conductive, the pin 79 serving to apply the necessary pressure. Each motor operates the lock through a pivoted quadrant 63. The sense of energisation of the motors is controlled by relays 100, 101, Fig. 7, and the time of energisation is limited to about a second by the charging of a condenser 105 through transistor T.

Abstract: 1309477 Resistance motor controllers ARROW-HART Inc 20 Nov 1970 [21 Nov 1969] 55202/70 Heading HIS In an electric current control device which uses an SCR phase shifting method a spring loaded trigger 14 carrying a bridging contact 24 when depressed closes contacts (22, Fig. 9, not shown) attached to terminal screws 21, and contacts 52 simultaneously. Further trigger movement causes rack 48 to rotate a gear 46 attached to a control potentiometer P and finally to close contacts 62 and by-pass the power control circuit. To ensure that the trigger of each device manufactured gives equal current for equal movement and to compensate for component tolerances a trimming potentiometer TP is included. This comprises a wiper and an arcuate resistance track (34, 32, Fig. 4, not shown) painted on a ceramic base (31, Fig. 4). The ends of the resilient arms 50, 60 are constrained in a slot in the trigger, each side of the slot having a ramp (50c, 60c, Fig. 7, not shown) to allow the arms to move sideways into contact with their respective mating contacts 54, 40c when the trigger is moved longitudinally. A plastics encased silicon controlled rectifier (SCR) or similar element is used to control the current and is fixed by a hollow rivet 44 to a metal plate 40 which acts as a heat sink. Electric flexes may be attached to terminal screws 21 and 15, the latter fitting into an internally threaded rivet (10r, Fig. 9, not shown) which is connected via tab 51 to the resilient arms 50, 60.

Abstract: 1376360 Non-woven fabrics JOHNSON & JOHNSON 16 Nov 1971 56274/72 Divided out of 1367944 Heading D2B Non-woven fabrics are made by treating fibres with an organic liquid or solution or an aqueous solution capable of swelling the fibres under conditions of concentration, temperature, and for a time such that the fibres are swollen, softened, and rendered limp without being solubilised, degraded, discoloured, or decomposed, and without the fibre surface being broken and wet-laying the treated fibres, the fibres having been maintained in a wet or damp, swollen, soft and limp state until wetlaying. The fibres, which are preferably from ¢ to 2 inches long, may be natural cellulosic fibres, wool, silk, regenerated cellulose, polyamide, polyethylene terephthalate, modacrylic or polyolefin fibres. The swelling agents for rayon may comprise solutions of water-soluble compounds such as alkali metal hydroxides, cuprammonium hydroxide, ammonia liquid quaternary ammonium compounds, strong acids, and strongly acidic salts such as ZuCl 2  and neutral salts such as LiCl. Swelling agents for polyamides include solutions of phenol, diethyl formamide, dimethyl formamide, formic acid, xylenol, trifluoroethanol, zinc chloride, chloral hydrate, and γ-butyrolactone. Swelling agents for polyolefins include toluene, xylene, carbon tetrachloride, tetralin, and decalin. Swelling agents for polyesters include phenolic solutions, chloral hydrate, and N-methyl pyrrolidone. Swelling agents for modacrylics include aqueous solutions of dimethyl formamide, diethyl formamide, dimethyl sulfoxide. After treatment with the swelling agent, the fibres may be washed or treated with a neutralising agent. Additives such as a polyethylene oxide solution may be added to disperse the fibres prior to web-formation, and the fibres of the web when made of synthetic fibres may be bonded by means of an aqueous resin binder emulsion or dispersion.
