Title: Coin-set credit mechanism
Inventor: HAMWIJK RUDI
IPC: G07F5/20
Filed: 1962-09-21
Abstract: 986,018. Prepayment mechanism for television apparatus. R. & R. RESEARCH Ltd. Sept. 16, 1963 [Sept. 21, 1962], No. 35981/62. Heading G4V. Coins 1 held in suspense on a shelf 3 against a stop 9, Fig. 1, are ganged for diameter by a jaw 8 moving on a carriage 4, the position at which a coin arrests the jaw determining the angular position of a disc 13 by engagement of cam face 11 with pin 12, this position determining which one of slots 16 in a disc 15 are presented to a feeler 17, final movement of the carriage 4 injecting the feeler into the selected slot 16 a distance such that rack 20 moving with the feeler rotates a credit establishing pinion in proportion to the value of the coin. Lost motion between the carriage 4, which is driven manually, and the jaw 8 and feeler 17 is provided by means of springs 6 and 19. When the feeler engages in a slot 16, thereby indicating a coin of acceptable diameter, a finger 22 projecting beyond rack 20 swings the stop 9 out of position to pass the coin to a cash box. Spring 10 on the face of jaw 8 propels the coin off shelf 3. If the coin is of an unacceptable diameter the feeler 17 makes no progress and the spring 19 compresses as carriage 4 drives to the left. During the forward motion of the carriage an associated spring loaded pawl rides over a trip mechanism, see Fig. 4 not shown, so that when the carriage returns the trip is actuated to pivot the shelf 3 and return any unacceptable coinage. In the modified arrangement shown in Fig. 6 it is not possible to obtain credit fraudulently by oscillating the carriage as is possible in Fig. 1 when the pinion 21 drives a credit mechanism through a one-way device. In Fig. 6 the rack 123 is normally disengaged from the credit establishing pinion 124 and is engaged by a cam 120 on the carriage 103 (which corresponds to carriage 4 of Fig. 1). A ratchet 127 holds the pinion 124 and consequently prevents return of rack 123 once it is engaged until the carriage 103 is returned to normal and cam 120 allows disengagement. Engagement of the rack 123 with pinion 124 is made coincident with release of the coin to the cash box. The positioning of the slotted disc 112 is determined by a pin 110 on a disc 111 following the back edge of ganging jaw 108 under spring bias. Once the feeler 117 has engaged a slot 118 in the disc, the rack 123 engages the pinion 124, the coin stop 109 is released and the jaw 108 ejects the coin, the pin 110 being left in position. In both embodiments the discs 13 and 15, or 111 and 112, may be comprised by a single disc.

Abstract: 413,691. Valve amplifying circuits. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Frink, F. W. ; 2, Eagle Street, Schenectady, New York, U.S.A.) Dec. 19, 1932, No. 36005. Convention date, Dec. 18, 1931. [Class 40 (v).] A vapour-filled discharge tube 13 is employed to operate a relay 9 which controls the alternate connection of a telephone set 8 to a high-frequency transmitter 1 and receiver 2. The tube 13 breaks down on the receipt of signals, and the potential across a resistance 21 and the anode circuit so reduces the biassing voltage on the grid of a second vapour-filled tube 14 that during the positive half-cycle of a generator 18 the tube 14 also breaks down and by reducing the anode current causes tube 13 to restore to inoperative condition. During the negative half-cycle of generator 18 tube 14 also becomes inoperative and tube 13 will break down again if signals are still being received. Resistances 20, 24 ensure that the tube 13 will break down on the receipt of signals even when the anode voltage is reduced by the operation of tube 14.

Title: Improvements in or relating to burglar alarm systems
IPC: G08B13/22
Filed: 1934-12-18
Abstract: 447,782. Burglar and like alarms. TIBBLES, H. J., Brodsworth, Blenheim Crescent, Leigh-on-Sea, and TIBBLES, H. C., 37, Muswell Hill, and RELY - A - BELL BURGLAR & FIRE ALARM CO., Ltd., 54, Wilson Street, both in London. Dec. 18, 1934, Nos. 36222/34 and 21289/35. [Classes 40 (i) and 118 (i)] The usual open or closed burglar alarm circuit installed in a building is connected to a remote indicator, for example, in a police station, and means are provided for giving an indication at the remote station both when the building circuit is set and when it is subsequently interfered with. A switch 4, 10 at the remote station connects contacts during the day so that, when the burglar alarm system at the building is set, a relay 1 at the remote station is energized and closes a switch 18 to complete a circuit including an audible alarm 19 and also closes a switch 20 to complete a circuit including a visual alarm 21. The operator, thus notified, moves the pivoted switch arm 4 away from contact 6 to engage contact 7, thereby de-energizing the relay 1 and energizing a relay 2 and moving the arm 10 so that the bridge contacts 11, 12 move away from the contacts 13, 14 and 15, 16 and the bridge contact 22 engages the contacts 23, 24. The relay 2 opens a switch 26. Upon subsequent interference with the burglar alarm system (which may be of the kind described in Specification 408,239 and may include switches arranged in series at points A, B, C) or severance of a land line 3 or 5, whereby the circuit of the relav 2 is broken, the switch 26 is closed to complete the circuit including the contacts 23, 24 and the audible alarm 19. The switch 26 may be made common to two circuits for audible and visual alarms respectively. Modifications are described (1) wherein only one relay is employed at the remote station and (2) wherein an indication is given either at the building or at the remote station, or at both, when the land lines are interfered with and also when they are bridged, an additional relay being energized when the resistance of the circuit is reduced by the act of bridging the leads. Thermostatic switches may be employed in conjunction with the burglar alarm system or in separate circuits to give an alarm at the remote station in case of a fire at the building. The source of energy for the circuit that includes the land lines, instead of being located entirely at the remote station, may be divided, one part being situated at the building and the other part at the remote station, so as to utilize for the closing of an alarm circuit the voltage reduction caused by bridging the land lines. Specification 402,166 is referred to. The first Provisional Specification refers also to Specification 386.345.

Title: Electrostatically bonded semiconductor on insulator mos device and a method of making the same
IPC: H01L29/22
Filed: 1976-09-02
Abstract: AN ELECTROSTATICALLY BONDED SEMICONDUCTOR-ON-INSULATOR MOS DEVICE, AND A METHOD OF MAKING THE SAME An electrostatically bonded semiconductor-on-insulator and particularly semiconductor-on-sapphire MOS devices are made of bulk materials.  A semiconductor body of a bulk material of less than about 75 microns in thickness is electrostatically bonded to an insulator substrate of a bulk material.  A dielectric layer of between 500 and 2,000 Angstroms in thickness is then formed on the semiconductor body to make a MOS semiconductor device and preferably a MOS field-effect transistor. The semiconductor-on-insulator MOS device is preferably made by first forming a major surface of the dielectric substrate and a major surface of the semiconductor body in planar configurations, applying a metal layer to the opposed major surface of the insulator substrate, and placing the planar surfaces of the body and substrate in intimate contact.  The assembly is then heated to at least 300.degree.C. and preferably at least 700.degree.C. while avoiding oxidation of the contacted surfaces, and thereafter applying an electrical potential of at least 700 volts between said metal layer and the semiconductor body to electrostatically bond the insulator substrate to the semiconductor body.  The electrostatically bonded assembly is then cooled at a rate less than about 10.degree.C. per minute to a temperature of about 300.degree.C. and preferably to room temperature.  Then, a dielectric layer and metal layer are applied on the semiconductor body to complete the semiconductor-on-substrate MOS device.

Abstract: 1275930 Sack holders EL CU ELETTROCUCITRICE INDUSTRIALE PORTATILE SpA 19 July 1969 36448/69 Heading B8C An apparatus for stretching sack mouths for closure by sewing comprises a reciprocable carriage 20 carrying spaced rods 10, 11 urged by springs 45 into a sack mouth and moved apart by means of a linkage 48, 50, 51 and springs 47 to stretch the mouth. The carriage 20 is reciprocated along guides 23, 24 by means of a chain 28 trained around drive sprockets 26, 27 and carrying a pin 30 connected to a vertically slidable member 32 on the carriage 20. The member 32 has arms 58 which engage projections (59, Fig. 3, not shown) on the rods 10, 11 to retain them in the raised position, downward movement of the rods 10, 11 also being blocked by a movable plate 46. Rotation of sprocket 26 in a direction G causes the member 32 to descend and the carriage 20 to move to the left from the position shown, the rods being returned in the raised position by the plate 46. When the carriage 20 is correctly aligned with respect to a sack, the plate 46 is removed and the rods 10, 11 rapidly extend into the sack mouth. Continued movement of the carriage 20 causes a roller 55 on the carriage to engage a fixed cam track 57 and be raised thereby, this causing the linkage 47, 48, 50, 51 to separate a pair of tubes 44 which contain the rods 10, 11. At the end of travel of the carriage 20 the rods 10, 11 are raised, the sack then being engaged by the sewing machine feed conveyer (Fig. 1, not shown), and the carriage returns to the start position.
