Filed: 1971-09-17
Abstract: 1410468 Washing apparatus J J K IRVINE 18 Dec 1972 [17 Sept 1971] 42232/71 Heading B8T A washing apparatus for tumblers comprises a container 10 with an annular plate 11 holding brushes 12 that co-operate with a second brush unit 14 holding brushes 15. The upright 16 has a detachable top 17 with jet apertures 19 and brush bristles 18. The flexible pipe 28 is connected to a tap and the amount of water flowing through the jet apertures 19 is set by the position of the collar 23 relative to the aperture 22. Normally the aperture is partially closed and water fills the container and overflows into a sink, while some squirts out through apertures 19. Detergent from a dispenser 33 flows to the container via the outlet 41 and is regulated by the valve 38. Varying sizes of glasses are cleaned by inserting a glass over brush unit 14 and moving it up and down with a slight twist motion. The glass can be slightly lifted up away from the container 10 so that water from the apertures 19 can give the inside of the glass a final rinse. In a modified version the container 10 is located in an outer jacket (44), Fig. 4 (not shown), with a splash plate (45), a water supply pipe (49) and waste pipe (48). Two of the washing apparatuses one with dispenser removed may be juxtaposed and used jointly for washing and rising glasses.

Abstract: 1344314 Laminates; seaming non-metallic sheet material MONSANTO CO 10 Sept 1971 [11 Sept 1970 14 Sept 1970] 42300/71 Headings B5N and B5K Layers of porous fabric containing a fibrous thermoplastic material are bonded together by (a) providing at least one of a pair of relatively movable electrodes 12, 13 with a resilient electrically insulating member 20, e.g. of silicone rubber, such that the electrode is flanked by the member and recessed therein, (b) placing at least two layers 10, 11 of the porous fabric made from fibrous thermoplastic material between the electrodes, (c) moving the electrodes towards each other to compress the resilient insulating member and thereby substantially to fill the voids in the porous fabric and to compress the layers between the electrodes and (d) supplying radio-frequency power to the electrodes to bond the layers together. Woven or non-woven fabrics, e.g. of nylon, may be bonded together. The terminal portion of at least one of the electrodes may be convex and a seam produced comprising a maximum bond area and a diminishing bond area contiguous with the maximum bond area and having its area of greatest bond intensity adjacent the maximum bond area and, over the remainder, a bond intensity that decreases as the distance from the maximum bond area increases. In Fig. 8 non-woven fabrics 110 and 111 contact each other as they pass over roller 113 and are fed between electrodes 120 and 121, electrode 120 being recessed in resilient insulating member 122 in housing 123 having arms 119. Housing 123 is connected to rod 128 which is connected to means for providing reciprocating motions and the pressure necessary to compress insulating member 122. Radio frequency source 124 is connected to electrodes 120 and 121 by means of lines 126 and 125 respectively. The bonded fabric is taken up on roll 129 which moves incrementally to allow for the bonding process. Layers of thermoplastic fabric may be bonded continuously along seam lines by mounting the relative electrodes and resilient insulating members on rotating drums. Various bond patterns may also be obtained using drums.

Inventor: O'SHEA ALBERT BASIL
IPC: B23K11/31
Filed: 1962-11-09
Abstract: 988,187. Welding by pressure. HIRST ELECTRONIC Ltd. Feb. 10, 1964 [Nov. 9, 1962], No. 42463/62. Heading B3R. An electrical welding apparatus comprises a movable electrode-mounting head biased to move away from a fixed electrode-mounting head and linkage means for transmitting pressure to move the movable head toward the fixed head, the linkage means including a lever pivotable about a displaceable fulcrum member biased against displacement by a spring in a holder having a bayonet connection with a fixed part of the apparatus. A fixed electrode 13 is carried in a head 12 secured to a housing 11 and a movable electrode 14 is secured in a head 15 on a slide located by balls between grooved guides for movement parallel to the axes of the electrodes. The slide carries an abutment 16<SP>1</SP> for one end of a compressed coil spring 22 the other end of which is held in a socket 11<SP>1</SP> on the housing and on the upper end of the slide bears a roller 23 carried at one end of a lever 24 pivoted to a fulcrum 26 and carrying a roller 25 at its other end. The spring 22 holds the roller 25 against the head 27 of a push rod assembly comprising an upper member 28 within which slides a member 28<SP>1</SP> with a stiff spring 31 arranged between flanges on the members to hold them apart and press the lower member 28<SP>1</SP> against a roller 32 initially abutting the housing. The roller 32 is carried on a lever 33 pivoted to a link 33<SP>1</SP> which is pulled down to actuate the apparatus. The fulcrum member 26 slidable in the top of the housing has a flange 35 initially in contact with the outside of the housing and a compressed spring 34 is arranged between the flange 35 and an adjustable stop 36 on a screw shaft 37 in a cover 38. The cover 38 is flanged at its lower end and carries three studs 42 engaging in key hole shaped slots 43 in the housing and is locked in position. The cover may be removed to fit a different spring 34. A switch 49 controlling welding current to the electrodes is engaged by the lower end of the fulcrum 26. In operation when the link 33<SP>1</SP> is pulled down the roller 25 is pressed upwardly, the spring 22 yields and the slide moves downwardly until the electrodes engage the work. The roller 25 continues to rise and rotates the lever 24 about the roller 23 so that the fulcrum member 26 is caused to rise against the spring 34 which mainly determines the electrode pressure and causes the switch 49 to switch on the welding current. The upper electrode may be secured to the slide by a number of leaf springs and relative movement of the electrode and slide is limited by a slot engaging a rigid bar. An adjustable stop for the roller 25 may be provided.

Title: Electrical remote control device
Inventor: MOWAT JAMES MCKINNON
IPC: H02P7/00
Filed: 1963-10-29
Abstract: 1,059,728. Protective arrangements. ANDERSON MAVOR Ltd. Jan. 29, 1965 [Oct. 29, 1963], No. 42550/63. Heading H2K. [Also in Divisions F2 and G3] An engine is started from a remote position by setting selector switch 10 at forward or reverse and closing switch 3, a master relay R5 being energized with rectified current, as well as one of the direction-determining relays R1 or R2. The circuit for these relays comprises a control winding 26 of transductor 25, and is completed through core 17 of a two-core cable having an earth conductor. Opening of switch 3 introduces resistor 4 to reduce the current to a holding value. The relays R1, R2, control electro-hydraulic valves EHV1, EHV2, for determining the direction of operation of the engine. Operation of switches 6 or 8 increases or decreases the speed of the engine by varying the resistance in circuit with the winding 26, thus causing the output current of transductor 25 to alter and set speed-controlling relays R3, R4, appropriately. These relays actuate speed - regulating valve - coils EHV3, EHV4, the speed continuing to vary while the respective switch 6 or 8 is held operated, and the new speed being maintained when the particular switch is released. The transductor has a bias winding 29 in series with preset resistor 30. In another embodiment, resistors 7, 9, are replaced by a speed-adjusting rheostat, and the transductor has a further balance winding for constant speed control in series with a resistor coupled with the speed-altering mechanism of the engine, Fig. 2 (not shown). A further modification provides a torque motor to replace the relays R3, R4, and a servo motor for constant load control which regulates a rheostat in the line 17. This servo motor is supplied from a magnetic amplifier which is controlled in accordance with deviations between a pre-set voltage and one derived from a current transformer in the supply circuit of an electric motor associated with the machine, Fig. 3 (not shown). The machine is stopped by opening switch 5, breakage of the cable having the same effect. Damage to the cable, causing a short-circuit, opens the master relay R5 which then receives unrectified current.

Title: Improvements relating to scale conversion apparatus
Inventor: SHEPHERD ALEXANDER TURNBULL
IPC: G06F1/02
Filed: 1968-09-19
Abstract: 1,240,882. Scale conversion device. FERRANTI Ltd. 11 Sept., 1969 [19 Sept., 1968], No. 44476/68. Heading G4A. A scale conversion device for converting N input pulses of one scale to D pulses of a closely related scale comprises means for inserting or inhibiting ID-NI evenly spread pulses. To interconvert imperial and metric scales, for example for a machine tool or a measuring probe, multiples of 001 inch (25.4 microns) are converted to multiples of 25 microns, i.e. an interconversion ratio of 127 to 125. To convert imperial to metric, electrical input pulses arrive at varying times on line 11 and are counted algebraically in a bidirectional binary counter 12 having a capacity of 125. The signs of the pulses are indicated by lines A and S. A diode decoding detector stage 13 applies a pulse over line 14 when the counter holds 31 pulses and a pulse over line 15 when it holds 93 pulses. These pulses pass through OR gate 16 and trigger a pulse delay and amplifier stage 17 to provide one pulse to OR gate 21. OR gate 21 also receives the pulses from line 11 and feeds a bidirectional counter 24. Thus for an algebraic sum of 125 input pulses at 11, 127 output pulses are received at counter 24, the extra two pulses being spaced by 125/127 - 125 #, 63 input pulses. Should the counter 12 reach 32 pulses and then count down, an appropriate negative pulse is generated. The delay in stage 17 prevents pulse loss by overlapping. When the counter 12 reaches 125 it returns to 0 and counts a fresh group. To convert metric to imperial, 127 input pulses are converted to 125 output pulses, and units 17 and 21 are replaced by an inhibit gate which suppresses two pulses per group. Instead of lines 11, A, and S, two rails may be provided, the sign of the pulse depending on the rail it arrives on (Fig. 6, not shown). A detector 13 for a 4-stage counter is described (Fig. 3, not shown) as is a unit 17 comprising two monostables. During the delay of a pulse arriving from unit 17 the sign of lines A and S may change and thus cause an erroneous pulse addition or subtraction. To prevent error a gating network (Figs. 4 and 5, not shown) generates a signal on the upward count at 32 and 93, and at 94 and 33 on the downward count). A modified counter using J-K flip-flops is described (Figs. 7 and 8, not shown), and Fig. 1 is modified using this counter in Fig. 10. On the arrival of the 31st pulse the five counter stages below stage D 5  are all one (i.e. 1111100 = 31) and stage D 5  is enabled by a pulse RD 5 . When the 32nd pulse arrives the generator 17 is triggered to give one pulse after a delay. A second single pulse is generated on the arrival of the 96th pulse. Counting down is again catered for as is modification from metric to imperial. A modification for interconverting scales of 100 and 127 is described (Fig. 17, not shown). Instead of a single pulse being added the next input pulse may be given the weight of two (Fig. 18, not shown).
