Abstract: 1,066,270. Combined desks and drawing boards. DARGUE BROS. Ltd. March 7, 1966 [Dec. 8, 1964], No. 49876/64. Headings A4B and A4H. A combined desk and drawing board unit comprises a drawing board 17 which can be stowed in the desk and which can be slid forwardly and then pivoted to its operative position, the movement of the board also causing the desk top 12 to pivot to a position in which it acts as a stay for the board. The rear edge of the board is pivoted to the front of a carriage 26 slidably mounted on a pair of slider bars 23 slidably mounted on bars 20 fixed to a side wall of the desk. A hook device 35 comprising two hooks (37) is fixed to the upper surface of the board in its stowed position and engages a cross-peg (47) on the end of a slide 38 slidably mounted on the underside of the desk top 12. The forward sliding movement of the board is thus stopped and the front edge of the board is then lifted. The slide 38 is held in its rearmost position by a tension spring  (41) which allows necessary movement of the slide during the pivoting of the board and the desk top. An interlocking device comprising a hook and a peg may be provided to prevent the top from being raised when the board is stowed. The slide for the board may comprise three channel sectioned slabs mounted one inside the other with ball bearings between adjacent surfaces (Fig. 9).

In an embodiment using a two track endless tape T, (Fig. 3), a head 8 reads a teaching tape 7 and the signals are passed, with a multiple switch 1 in the position shown, to. an amplifier 9 and loudspeaker 10 for reproduction, and also to an amplifier 11 and head RP 1 for recording on one track of the tape T. Concurrently a pupil may use a microphone 18 and amplifier 19 to record on the second track on the tape T. Both recordings have bias signals from an oscillator 12 superimposed, the oscillator signals also being used by the erase heads E1, E2, and if the switch 1 is thrown the recordings on T are played back through the amplifier 9 and loudspeaker 10 after one revolution of T.

The multivibrator comprises two inverters A, B each formed from a complementary pair of MOSFET's, the inverters being cross connected input to output, one connection being direct, the other via resistor 12 and capacitor 21. Diagonally opposite FET's conduct simultaneously, charging capacitor 21 via resistor 11 until their gate-source voltage falls to a critical level, when conducting and non-conducting FET's interchange and the direction of charge is reversed. The effect on the periodic time of fall of supply voltage (Fig. 3, not shown) as capacitor 20, initially charged from, e.g. induction current generator 9, discharges is compensated by resistor 13 and capacitor 22, the setting of 22 being related to the capacitance 20 and the apparent input capacitance 23 of the multivibrator. The effect of resistor 13 can also be achieved by inserting tapped resistors at point 1 and at the corresponding junction point between FET's 51, 52 (Fig. 4, not shown).

Ends of tape cables may be inserted into sheaths 11, 21, an exposed conductor of each cable end being disposed in each tubular member 12 together with a ring of solder; alternatively, the conductors may be tinned. When the assembly is heated, the conductors are soldered together and the sheaths 11, 21 and tubular members 12 shrink down to seal and provide strain relief for the connections. Alternatively, one of the sheaths may be shrunk on to a terminal block, the terminals of which extend into tubular members 12, wherein they are soldered to the conductors of a tape cable inserted in the other sheath. Fig. 5 depicts a heatshrinkable member 22 comprising a single sheath 25, and integral tubular members 26 adapted to be shrunk around bosses 30 of a connector block 28, to enable terminal ends of socket contacts 31 protruding through the bosses to be soldered to conductors 32 of a tape cable 27 inserted into sheath 25.

Abstract: 1,146,198. Flat glass manufacture. NIPPON PLATE GLASS CO. Ltd. 15 Nov., 1967 [17 Nov., 1966 (2)], No. 52042/67. Heading C1M. [Also in Divisions G1 and G3] In a process for the continuous production of sheet glass by flowing molten glass on to a bath of molten metal (e.g. tin) the position of the side-edges of the sheet is detected by electrodes mounted at a point along the edge where the glass is hot enough to be electroconductive. Contact of the glass edge with the electrodes provides a signal for indicating strip width and/ or controlling the input of molten glass to automatically maintain constant strip width. As described, Figs. 4 or 6 (not shown), a number of electrodes either side of the strip are arranged to connect resistors in parallel in the supply circuit to a meter. It is stated that the signal may be used to control the tweel actuating motor at the glass feed inlet. Alternatively electrodes may be provided at one edge only to give an alarm signal and shut down the glass supply if the strip width is excessive, Fig. 2 (not shown). The electrode contact is preferably of graphite which is not "wetted" by the glass; an electrode assembly is illustrated in Figs. 7, 8 (not shown).

Abstract: 1,141,657. Counters. VEEDER INDUSTRIES Inc. 17 Nov., 1967 [14 March, 1967], No. 52358/67. Heading G4D. Transfer-assist mechanism comprises a load- and-fire assembly in combination with a spring- clutch which prevents overthrow. The units wheel 22 of a meter is driven by a gear 78. A hub gear 68 on the wheel engages an epicycle gear 64 integral with gear 62 carried by a lever 50, the gear 62 meshing with a hub gear 74 on the tens wheel 24. The units wheel also drives a gear 110 of the spring-clutch mechanism through a Geneva wheel 86. The output gear 104 of the spring-clutch mechanism normally holds gears 106, 108 and therefore the tens wheel 24 stationary so that rotation of the units wheel 22 causes epicyclic gears 64, 62 to turn round the gear 74, carrying lever 50 clockwise against the action of spring 46. At transfer the Geneva wheel 86 steps gear 110, the connection at 116, 118 loosening the grip of spring 100 on barrel 102. Spring 46 is now able to turn lever 50 to effect a smooth rotation of the tens wheel. Overthrow is prevented by tabs 122, one of which engages in a narrow slot 124 on wheel 104, the other in a longer slot 126 of disc 112 integral with gear 110. The power stored in spring 46 enables successive transfers through subsequent Geneva mechanisms.
