Abstract: 1,228,865. Reciprocating conveyers. JERVIS B. WEBB CO. 9 May, 1968 [10 May, 1967], No. 21939/68. Heading B8A. Workpieces 10 supported on parallel rails 13, 14 are movable between stations A-E by pushers 26 pivotally mounted on a driving member 28 and controlled by sensing devices 56 provided for each station. Each device 56 comprises a rotatable shaft 58 to which are attached an object-engaging arm 60 and a pusherpositioning arm 62, the latter acting as a counterweight to bias the device 56 such that the arm 60 tends to take up the position shown at 60d. In the corresponding position of arm 62, a controlling tab 64 or 64a is in the path of a tab 51 or 51a mounted on an element 50 fixed to a shaft 46 of the pusher 26 shown between stations B, C. When a device 56 is depressed by a workpiece, e.g. as at stations A, B, C, E, no engagement of tabs 51, 51a by tabs 64, 64a takes place. Pusher elements 50 are linked by cables 52 and the driving member 28 is reciprocated by a piston-cylinder unit 36, 40. As the member 28 moves on its return stroke the pushers 26 engage workpieces at stations A, B, C, are pivoted to non-operative positions and, due to cables 52, cause similar pivoting of successive pushers, e.g. those to the left of the first three pushers. In the absence of a workpiece at station D, the sensing device 56 associated with this station takes up the position 60d and, just prior to the end of the return stroke of the driving member 28 causes the third pusher from the right to move to the operative position shown. Simultaneously the second and first pushers are moved to operative positions by the cables 52 and the workpieces at stations A, B, C are each moved one station to the left upon the next forwarding stroke of the member 28. Reference has been directed by the Comptroller to Specification 1,118,587.

Abstract: 1,230,724. Bottling &c. KARTRIDG PAK CO. 28 May, 1969 [1 April, 1969], No. 26879/69. Heading B8T. A filling machine fills containers C which have a valve (V), Fig. 2 (not shown), in a recess in their bell-shaped base with a material under pressure. The machine comprises successive work stations 10 and may be of rotating table type. Heads 14 move vertically, controlled by a cam, and may be lowered to engage a sealing bell 19 with the container top to apply a vertical pressure. The supporting platform 20, being resiliently mounted on the table 12, is depressed and the valve (V) lowers into engagement with the filling head 30. After engagement a valve in the head 30 is opened by the pressure of the filling material delivered by the conduit (50), Fig. 2 (not shown), from the metering device 51. The heads 14 may be used to incorporate mechanism to charge an aerosol container with a product and then crimp on a closure member 15 after which propellent is charged through the base as described.

Abstract: 1,239,534. Bolts; rivets; nails. M. MELAND. 12 Feb., 1970, No. 6893/70. Heading F2H. [Also in Division A4] A data-carrying card 6 is removably retained against a wood or fibre-board surface 3 by the limbs of a U-shape spring wire member 1 having bent-up ends 2 which are hammered into the surface. The ends are bevelled at 4 so that on hammering they deviate downwardly and cause the limbs to bear resiliently against the surface 3. The angle between the limbs and the ends 2 is preferably less than a right angle, so that when the member is placed on the surface, prior to hammering, the ends are normal to the surface, and the part 5 of the member is bent forwardly to facilitate raising by the fingers for insertion of the card.

Abstract: 1,265,753. Pulse thresholding and regeneration. CREED & CO. Ltd. 30 May, 1969, No. 27473/69. Heading H3T. A pulse regenerator comprises a differential thresholding circuit 12, 15 to which is applied the input pulses and a threshold value equal to a fraction of the peak pulse level, a splitting circuit 21, 22 for dividing the resulting signal into positive and negative parts and respective switching networks 24, 28 and 30, 33 having feedback operative to change the signal level at which the switching networks operate. As shown, the feedback is applied to the common input 19 via resistor 35 and ensures that the signal must change to a level beyond the initial switching level before the networks restore. The input to the circuit may be derived from an isolating network (Fig. 2) in which the input signals control the passage of oscillation to a demodulator.

Abstract: 1288752 Railway systems TRACKED HOVERCRAFT Ltd 7 Oct 1969 [11 July 1968] 33182/68 Heading B7L [Also in Division H2] The stator of a linear induction motor has at least one part which is movable by an actuator to vary the gap between said part and the reaction rail and thereby control the thrust of the motor. As shown in Fig. 2, the stator, which is carried by a track-guided, air cushion vehicle, comprises two parts 13 located on either side of a reaction rail 14 and carried by arms 26, 27 pivoted to a cross-member 23. The ends of arms 26, 27 are coupled to a doubleacting hydraulic actuator 28 adapted to swing the parts 13 towards or away from rail 14. Further thrust control may be obtained by moving the stator parallel to the rail at right angles to the longitudinal axis by hydraulic actuator 16. Fig. 3 shows a modification in which the parts 13 remain parallel to rail 14 as they are moved towards or away from it by telescopic actuators 28. To permit this the rear portions of the stator parts slidingly interengage at 29.

Electrolytic pickling may be carried out in an acid solution containing 2-25% SO 4  and/or 2-20% PO 4  ions, added as acids, salts or acid salts of alkali metals or Mg. A phosphating treatment, e.g. using a 1-5% solution of magnesium dihydrogen phosphate, may be carried out between the pickling and metallizing stages. Enamelling may be carried out by electrostatic or electro-phoretic deposition, preferably of low oxide frits firing below 760 C., e.g. B-Ti white enamel. A pickling mixture for steels is exemplified: 15-20% H 2 SO 4 , 1-3% HNO 3  and 2-4% urea.

Abstract: 1295947 Road traffic signals on vehicles F K HARBERT 26 Feb 1970 [8 May 1969] 9312/70 Heading G4Q A vehicle stop warning system includes a rear-mounted sign 16 showing the word STOP illuminated by a bulb 17 connected to a battery 11 through normally-open relay contacts 28, 29 and parallel-connected switches 14, 15 operated respectively, by a brake pedal 12 and hand brake lever 13. The relay coil 25 is connected between the switches 14, 15 and contacts 36, 37 engageable by a contact arm 24 operable by a lever 23. The lever 23 is manually operated and mounted on the vehicle steering column and may be displaced in either one of two directions so that arm 24 engages contact 36 or 37, the lever returning to the neutral position shown on release of the manual pressure. The coil 25 is also connected to earth through holding contacts 31, 32. In order to illuminate the stop sign 16 brake pressure must be applied to close switch 14 or 15 and lever 23 must be flicked over so that contact 24 momentarily engages contact 36 or 37. This energizes coil 25 to close holding contacts 31, 32 and also close contacts 28, 29. Thus, the stop sign bulb 17 remains illuminated so long as switch 14 or 15 remains closed. The arrangement of the components on a car is described with reference to Fig. 1 (not shown) and the construction of the relay, manually operated switch and stop sign is described with reference to Figs. 5-12 (not shown).

Abstract: 1315673 Digital computers; error detection KOMBINAT ROBOTRON VEB 12 June 1970 28667/70 Heading G4A A circuit arrangement determines whether errors in a digital computer are temporary or permanent by counting the number of times that an error is repeated.  A computer 1 executes an operating step under control of data in control register 2, which data is transferred to a holding register 6 by a circuit 7. Error detection circuits 4 detect any errors in the execution of the step and inform a fault control circuit 5 which causes the contents of register 6 to be returned to register 2, thus repeating the step. A counter in circuit 5 classifies a fault as permanent after a predetermined number of repetitions. If there is no error fresh data is fetched from control unit 3. In another embodiment (Fig. 2, not shown) the computer is microprogrammed and the transferred data is the address of a microinstruction.
