In examples: (1) water was mixed with a condensate of propylene oxide and glycerol and matured for 6 hours before reaction with toluene diisocyanate in the presence of triethylene diamine, stannous octoate, N-methyl-morpholine and silicone oil; (3) maturing time was 24 hours with reactants as in (1).
Patent GB-155274-A (GB)
Title: Electric winch with automatic stopping arrangement
IPC: B66D1/12
Filed: 1920-12-14
Abstract: 155,274. Bobst et fils, Soc. Anon., J. March 1, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Winches; regulating and control-transmitting gear; stopping automatically at end of run.- Comprises means for stopping an electricallyactuated winch automatically when the load has been raised or lowered to a predetermined point. 'The controlling-handle 13 of the winch has a central position of rest and a movement to the right or left to the points 13", 13' corresponding to the positions for lowering and raising the load respectively. The movement of the handle 13 from its central position to start the motor in one direction or the other, rotates pulleys 15 on the handle shaft and transmits the movement by crossed belts to other pulleys fixed on a shaft 21. This rotation of shaft 21 performs two functions as follows : (1) A gear-wheel 20 engages a rack on a sliding bar 18 and moves it axially against the action of one or other of the opposed springs 40, 41. This displacement of the bar moves a recess 46 therein out of register with a disk on a sliding rod 48 and thus forces the rod 48 downwards to release a spring-applied brake from a pulley on the motor shaft. Pins 66<1> on the sliding bar also actuate a T-piece pivoted at 59 so as to move the controlling-spring 61 to opposite sides of the dead-centre of the T-piece, thus bringing one or other of the arms 63 into position for dropping into line with notches 65 in the sliding bar when this is returned to the neutral position. This mechanism prevents the controlling-handle from being moved successively twice in the same direction, for example, if a load has been lowered and the controlling-handle returned to neutral position, the engaged arm 63 prevents the movement of the sliding bar in the direction for lowering again, until the T-piece has been swung over by a subsequent lifting of the load. (2) A wheel 22 is rotated until one or other of two notches 23, 24 engages a lug 32 on a spring-controlled arm 30. This mechanism locks the sliding-bar 18 in its adjusted position. Meanwhile the rotation of the winch drum is communicated through reduction spur gearing to a third wheel 25 loose on the shaft 21. The wheel 25 carries two adjustable pins 26, which can be positioned angularly on the wheel to correspond with predetermined stopping-points for raising and lowering. The rotation of the wheel 25 eventually raises the arm 30 by bringing the corresponding- stop into contact with a cam 33 thereon. The raising of the arm 30 releases the wheel 22 and allows the springs to restore the sliding bar 18. This movement restores the controlling-handle to neutral position and allows the brake to be re-applied to the motor shaft.

A method of copying-machining a workpiece by planing, turning or milling comprises forming a tracer as a template t<SP>1</SP> to coact with a template t<SP>2</SP> at right-angles thereto to thereby produce a three-dimensional shape. A planing tool T, on a slide 2, and the tracer template t<SP>1</SP> are reciprocated by a ram 4. The workpiece W and the template t<SP>2</SP> are fed intermittently in the direction A. The template t<SP>1</SP> is mounted in a frame F and can be deflected vertically and laterally to actuate an hydraulic tracer valve 7. A rocking template t<SP>1</SP>x, Fig. 2, may produce a turbine blade wx by coacting with two other templates t<SP>2x</SP>, t<SP>2</SP>y. The template t<SP>1</SP>, Fig. 5, has a rounded edge similar to the tool and is carried by a bar 18 pivoted in an arm 22 urged about a pivot 14 by an adjustable spring 21, which also serves to counterbalance the weight of the assembly. The bar 18 carries a projection 19 to engage a recess in the tracer valve 7. The tracer assembly is supported on the head 11 by a split bracket 10. The tracer may be as described in Specifications 692,642, 859,474 or 860,697.

Title: A semi-conductor device
IPC: H01L29/00
Filed: 1960-10-17
Abstract: 950,849. Semi-conductor devices. MONSANTO CHEMICAL CO. Oct. 17, 1960 [Oct. 16, 1959 (3)], No. 35464/60. Heading H1K. A semi-conductor device said to be particularly suitable for use at high temperatures comprises a semi-conductor of cubic crystalline boron phosphide, a high melting point conductor attached to the semi-conductor and forming an ohmic junction and at least one other conductor forming a rectifying junction. Fig. 1 shows a point contact rectifier. The wafer 12 is a single crystal of N-type cubic boron phosphide. The rectifying contact is formed by a whisker 13 of tungsten or phosphor bronze pressed into contact with the wafer by a force of 10 to 100 grams. The point contact may be welded to the wafer by a current surge; the other end is soldered, welded or held in mechanical contact with an electrode 15 which may be of copper or nickel. The ohmic connection is made to the wafer by means of a nickel electrode 14 containing 10% by weight of selenium or tellurium. Wafer 12 and electrode 14 are pressed together at 1000 C. to make the weld. A glass capsule 16 which may be evacuated is provided. In an oxidizing high temperature atmosphere leads 19, 20 should be nickel, otherwise copper is satisfactory. The ohmic contact may be made by fusing platinum to the lower surface of the wafer. Wafer 12 and the electrode may be joined by silver paint. Fig. 3 shows a transistor with two point rectifying contacts 33, 34 and a rectifying contact 35. The point contacts are of tungsten or phosphor bronze and may be pressed into contact with the wafer or welded to it by a current surge. Conductor 35 is of platinum or of nickel containing selenium and tellurium. The leads may be nickel or copper. A junction transistor is described with reference to Fig. 4 (not shown) in which an ohmic junction is made by firing platinum or nickel to the edge of an N-type wafer and the rectifying contacts are made by alloying nickel conductors each containing cadmium or zinc to the opposite face of the wafer. Alternatively mercury, beryllium or magnesium may replace the zinc or cadmium. Similarly oxygen sulphur or potassium may replace selenium or tellurium. A junction rectifier is also described (Fig. 5, not shown) with a nickel or platinum ohmic contact as already described and a nickel cadmium rectifying contact. The wafer may have an internal PN junction made by diffusing a Group IIB metal into e.g. cadmium, magnesium or beryllium into one side of a wafer of N-type boron phosphide. In another method a donor or acceptor may be added or charged during the crystal growth. Finally P-type boron phosphide may be made by heating boron phosphide in a vacuum. Specifications 931,335, 931,336, 942,559 and 942,560 are referred to.

Title: Improvements in and relating to grinding machines
IPC: B24B19/12
Filed: 1965-08-19
Abstract: 1,106,180. Grinding. LANDIS TOOL CO. 19 Aug., 1965 [20 Aug., 1964], No. 35618/65. Heading B3D. In a cam grinding machine relative transverse movement between a grinding wheel 30 and a work support is effected by at least two sets of master cams and a master cam follower 25, the latter being selectively engageable with the master cams of each set. A master camshaft 20 has two sets of master cams A, B arranged alternately; the two sets may be formed on separate axially spaced shafts. The master cams are ground, using a grinding wheel of substantially the same diameter as the follower 25 which is to engage the master cams, under the control of a model cam, of the same size as the product cam, and a follower roller. When grinding the master cams A the follower roller has a diameter halfway between that of the full size grinding wheel and a half-worn wheel. When grinding the master cams B the follower roller has a diameter half-way between that of the half-worn wheel and the minimum diameter wheel. The follower 25 is initially in register with the master cams A, being moved from one master cam to the next by mechanism as in Specification 355,475. When the grinding wheel 30 has been reduced by wear and dressing to the permissible minimum diameter for use with cams A, a cam 55 on a dressing device 56 closes a limit switch; when the master cam-shaft is moved away from the follower 25 another limit switch is closed; the closure of both limit switches energizes a solenoid moving a valve so that a piston is operated to shift the follower 25 into register with the master cams B.
