Abstract: 1,098,358. Battery charging systems. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Sept. 7, 1966 [Sept. 8, 1965], No. 38354/65. Heading H2H. [Also in Division G3] A battery charging circuit includes A.C. input terminals 5, 6; a controlled rectifier bridge including diodes 1, 2 and thyristors 3, 4; output terminals 11, 12 for connection to the battery (not shown) under charge; resistors 8, 9, 10 for sensing the charging current; a sensing circuit including a voltage divider 14, 15, a resistor 16 and a transistor 18 associated with a diode 13 and a capacitor 20 for detecting the battery charging voltage; and a controller 17 to which are applied signals from the current and voltage sensing circuits and which provides triggering pulses for the thyristors 3, 4, in a suitable manner to maintain a desired charging characteristic for the circuit. The arrangement is such that in general the battery is charged first at constant current in dependence upon the current control signal and then at a constant floating voltage of VI (see Fig. 2) when the voltage control signal supersedes the current control signal; however, when the battery voltage first attains the value VI, at the point B of the curve shown in Fig. 2, the voltage signal to the controller 17 is modified by the action of transistor 18, the base of which is connected to the resistor 10 carrying the charging current, in such a manner that the thyristors 3, 4 are controlled to allow the battery voltage to rise first to a predetermined value V2 before falling again to the voltage VI so that the charging characteristic of the circuit assumes the form BAC, Fig. 2, there being a controlled decrease in charging current over this range.

Title: Method of making a powdered coating material
IPC: C09D7/80
Filed: 1972-08-21
Abstract: 1400861 Powdered coating materials GROW CHEMICAL CORP 21 Aug 1972 [5 Oct 1971] 38916/72 Heading C4A Powdered coating material is made by finely dividing a liquid coating material comprising a solvent portion, a film forming portion and a pigment in the presence of a coagulating liquid, in which the solvent portion is soluble and the film forming portion and the pigment are insoluble, and diluting the droplets formed with the coagulating liquid so as to precipitate the non-solvent portion of the liquid coating material in powder form. The process can be carried out by adding the liquid coating material to the coagulating liquid, adding the coagulating liquid to the liquid coating material or by adding to the liquid coating material an amount of coagulating liquid which is less than the amount necessary for coagulation and then finely dividing and diluting the mixture in the presence of a further amount of coagulating liquid. The powder precipitated can be screened and oversize and/or undersize particles redissolved and recycled. In examples a liquid paint containing carbon pigment and acrylic ester resin dissolved in acetone and naphtha is precipitated with water and a liquid paint containing titanium dioxide, lampblack, talc and thermoplastic resin dissolved in acetone is precipitated with water.

Filed: 1962-10-15
Abstract: 956,658. Semi-conductor switching circuits; automatic exchange systems. M. J. A. MENORET, and M. M. ROUZIER. Oct. 15, 1962 [Dec. 14, 1961], No. 38943/62. Headings H3T and H4K. A switching circuit for effecting connection between co-ordinate points in a switching matrix in an automatic telephone exchange comprises a transistor 11, a tunnel diode 12 connected between the emitter and base electrodes of the transistor and poled to be forwardly conducting in the same direction as the emitterbase diode, and a rectifier diode 13 connected in series with the emitter-collector path of the transistor in the collector circuit thereof and poled so as to conduct normal collector current flow through the transistor, the tunnel diode being so biased through a resistor 14 from a voltage source that it may assume either of two stable states, in the low-voltage one of which the voltage across the tunnel diode is insufficient to render the transistor conducting so that it presents a high impedance to a circuit connected in series with its emitter-collector path and in the high-voltage one of which the voltage across the tunnel diode is sufficient to cause the transistor to saturate and present a low impedance to the circuit connected in series therewith. The simultaneous application of a positive pulse to the emitter electrode and a negative pulse to the base biases tunnel diode 12 and rectifier diode 15 forwardly to switch the tunnel diode to its high-voltage state in which transistor 11 becomes conductive to complete a circuit between terminals 10 1  and 10 2 . The transistor is returned to its non-conductive condition by interrupting the earth connection to terminal 10 1 . Fig. 3 shows the switching circuit connected between co-ordinate conductors 101, 201 of a switching matrix to complete or interrupt the circuit between signal transformers 21, 31. The simultaneous application of pulses of the polarities shown to the bases of normally non-conducting transistors 41, 51 switches transistor 11 into saturation and completes the path through normally conducting transistor 22 between transformers 21 and 31. Transistor 11 is switched off by the application of a positive pulse to the base of transistor 22 which renders this transistor non- conducting and interrupts the current supply to tunnel diode 12. Rectifier diode 13 prevents reverse current flow through the collectorbase diode of transistor 11 and the tunnel diode 12 if line 201 should go positive with respect to line 101.

Title: A toy with a track for a toy vehicle
IPC: A63H18/00
Filed: 1966-09-01
Abstract: 1,085,110. Toys. A. EINFALT and J. EINFALT [trading as GEBRUDER EINFALT BLECHSPIELWARENFABRIK], Sept. 1, 1966 [Feb. 11, 1966], No. 39036/66. Heading A6S. The toy consists of a fixed track which rises at each end from a central low position. A start station is provided at one end and a stop at the other. Positioned above the fixed track is a tiltable track which tilts about a transverse axis but runs in a generally parallel direction to the fixed track. In its normal position the portion at the start station side of the axis, which has a toothed track, being heavier, rests with its end on the intermediate low portion of the fixed track. Arranged above the stop end of the fixed track and partly above the tiltable track is a superstructure which has another track which has a gradient similar to the portion of the fixed track it is built over. On this upper track is a vehicle which has a depending member projecting down towards the tiltable track. A clockwork vehicle is held in the start station by a latch U. When released it runs down, under gravity towards point i where it comes into contact with the toothed portion of the tiltable track e. The clockwork motor is triggered by the teeth and carries the vehicle to the top of the section. As it passes the axis f it strikes the depending member r, of the other vehicle m and knocks it along its track. Meanwhile the track under the clockwork vehicle tilts and it runs, under gravity down to join the fixed track again, continuing up to the stop h. It is reversed by the rebound and runs back down the track g, passing under the part of the tilting track e' which has returned to its rest position. It then strikes e, knocking it out of the way and hence returns to the start station. The other vehicle has in the meantime returned to its rest position, also under the effect of gravity.

Filed: 1959-11-18
Abstract: The walls of microcapsules comprised of at least one gelable hydrophilic colloid which contains amino groups and peptide linkages and produced by a coacervation process (see Group VI) are rendered opaque and their impermeability to fluids increased by successive treatment with (a) at least one watersoluble and ionizable ferric salt and, (b) an aqueous solution of one or more of tannic acid, gallic acid and di-gallic acid.  Specified colloids of the above type are gelatin, fibrinogen, polylysine and polyrnithine.  Specifications 751,600, 911,483, 929,401, 929,402, 929,403, 929,408 and 929,409 are referred to.ALSO:Membranes comprising at least one gelable hydrophilic colloid which contains amino groups and peptide linkages (e.g. proteins and polyamines) and produced by coacervation techniques are treated successively with: (1) at least one water-soluble and ionizable ferric salt and (2) an aqueous solution of one or more of tannic acid, gallic acid and digallic acid.  The membranes may encapsulate solids, oils, oil-in-hydrophilic liquid and hydrophilic liquid-in-oil emulsions which may contain "active" ingredients which render the preparations of use as fertilizers, plant growth hormone preparations, bactericides, pesticides, vitamin preparations, pharmaceuticals and food-additives.  In particular, the treatment renders the membranes opaque and therefore increases the stability of encapsulated preparations comprising photosensitive materials, e.g. reserpine, hyoscyamine, potassium iodide, silver salts and phenyl mercuric acetate. Specified colloids are gelatine, fibrinogen, polylysine and polyornithine.  The coacervate must be gelled (e.g. by cooling) prior to the treatment with the ferric salt and may be present in the "spent" coacervating medium during the first or both steps of the treatment which preferably takes place at a pH of below 7. Specific examples refer to the treatment of: (a) aqueous potassium iodide-in-corn oil emulsion encapsulated in gelatine; (b) an ethanolic dispersion of silverbromide-in-silicone oil emulsion in gelatine; (c) aqueous epinephrine bitartrate-in-mineral oil emulsion in a complex coacervate of gelatine and styrene-maleic anhydride copolymer; (d) glyceryl monostearate coated yellow mercuric oxide in gelatine.

Abstract: 1373602 Grinding gears WERKZEUGMASCHINENKOMBINAT "7 OKTOBER" BERLIN VEB 23 Aug 1972 39205/72 Heading B3D A gearwheel-cutting machine has a device for positioning a gearwheel 1 relative to a tool 2 comprising a carriage 17 on which is mounted an arm 15 carrying a positioning pin 14 adapted to engage a tooth gap of the gearwheel, driving means 20 for moving the carriage so that the arm and pin move tangentially of the gearwheel, a stop member 26 on the carriage or driving means co-operable with an abutment 27 on a fixed guide for the carriage or on a fixed member of the driving means, and a pressure member 11 acting on the gearwheel in a clamping position for machining, an initial pressure of the member being such that the gearwheel can only be rotated by the pin when the latter has entered a tooth gap, the pin being withdrawn from the gap upon the gearwheel being clamped fast by the pressure member. The tool 2 is moved linearly by a ram 3 on a part 4 adjustable about a horizontal axis to the helix of the workpiece. The tool is adjusted in relation to the gearwheel by an upright 5 and is retracted after a grinding operation by a slide 6. The gearwheel is held on a clamping device 7 carried by a circular table 8 on a bed slide 9 which, for holding of the gearwheel is moved along a bed 10. The positioning device 13 is carried by an arm 16 from the rotatable part 4 and consists of a guide (18, Fig. 4, not shown), along which the carriage 17 is movable by a hydraulic cylinder 20 having its rod 19 connected by a bridge 21 to the guide. The arm 15 is mounted on a pivot 22 on the carriage and is urged by a spring 23 against an adjusting screw 25. The arm can be moved away from the screw 25 by a hydraulic cylinder 28 a distance limited by a stop 24. In operation, the gearwheel is placed on the clamping device 7 and the pressure member 11, in the form of a dome, is lowered to hold the gearwheel with a light pressure. The carriage 17 is advanced by the cylinder 20 so that the pin tangentially engages the gearwheel. If the pin engages the head of a tooth the arm moves against the spring 23 until the pin engages the gap between a pair of teeth and rotates the gearwheel to a position determined by the stops 26, 27. The gearwheel is then clamped fast by the pressure dome and the cylinder 28 actuated to retract the pin from the teeth for return movement of the carriage. In another embodiment, the device is mounted on the slide 9 or bed 10 and the retracting movement of the pin is effected by a further slide.
