Title: Road vehicle rear signal lamp circuits
IPC: B60Q1/30
Filed: 1972-05-16
Abstract: 1435917 Road-vehicle signal lights LUCAS ELECTRICAL Ltd 4 May 1973 [16 May 1972 20 May 1972 5 Sept 1972] 22810/72 Heading G4Q In a road vehicle rear signal lamp circuit lamp dimming when the lights of the vehicle are on is achieved by supplying intermittent power to the lamp at a frequency such that the lamp appears to be continuously illuminated. In an embodiment incorporating a lighting switch 12, ignition switch 14, a conventional flasher unit 15, a direction-indicator switch 16, rear flasher lamps 19, 23, brake switch 26 and stop lamps 28 the operation is as follows: Switch 12 open.-No power is supplied to; a multivibrator 31, 32. When brake switch 26 closes a transistor 27 is saturated and lamps 28 are illuminated at full intensity and similarly for direction-indicator lamps. Switch 12 closed.-The multivibrator is energized and appropriate rear lamps appear to be illuminated continuously but at reduced intensity. It is arranged that the flashing rate is substantially constant. If a hazard warning switch (not shown) is operated to illuminate all flasher lamps simultaneously, lamps 19, 23 are at full intensity even when switch 12 is closed. It may be arranged that the stop lamps are dimmed by a different amount from the flasher lamps. A current-sensitive element may be included in series with transistor 27 to ensure that power is supplied continuously to lamps 28 until they are hot, and similarly for the flasher lamps.

Title: Improvements in autographic registers
IPC: B41L5/08
Filed: 1956-07-30
Abstract: 836,887. Autographic registers. FANFOLD Ltd., and COOKE, G. H. Oct. 11, 1957 [July 30, 1956], No. 23517/56. Class 16 In an autographic register having one or more interleaved transfer material webs drawn over a recording position transversely to the superposed webs of continuous form stationery, there is provided stationery advancing means which on actuation first advances the stationery webs from the recording position and then releases them for further advancement by hand and a pair of co-operating rollers with interengaging projections for gripping between them one or more webs of transfer material and which are so coupled to the stationery advancing means that actuation thereof drives the rollers to draw the web or webs of transfer material past the recording position during the advance of the stationery by the stationery advancing means. The zig-zag folded stationery is stacked on the floor 9 of an inner housing 8-11 within the main housing 1-6 and passes over the top 8 which acts as the platen. A bracket 12 at the rear of the inner housing carries a spindle 13 on which a channel-shaped member 14 is journalled, the member 14 being held by coil springs 15 in the position of Fig. 3, and movable rearwardly and downwardly by a key 16. The member 14 carries a pair of fingers 18 which pass through slots in the platen 8 to engage perforations at the end of each form length to give the initial advance movement of the forms which are then pulled out by hand. As the key 16 is depressed, a lug 22 on each finger 18 runs along under a guide member 23 and over a blade spring 24, the member 23 forcing the finger 18 downwardly, at the end of its forward travel, to release the form, the lug 22 then passing under the spring 24 to hold the finger 18 depressed while the form is pulled thereover, the key 16 being returned by the springs 15 and the lugs 22 passing eventually through shoulders in the springs 24. The carbon webs are fed from a spindle 25 over the platen 8 to between a pair of rollers 32, 33 each having longitudinally extending ribs. The spindle 25 androllers 32, 33 are journalled in slots in flanges 26, 34 at the rear end and open slots in similar flanges at the front end, the spindle 25 and roller 32 each being held down by a spring 28 attached between rings 29, 30 fitting over the end of the spindle or roller and a fixed stud 31. Operation of key 16 is used to advance the webs by means of a ratchet wheel 36 on roller 32 engaged by a resilient pawl 40 carried by a lever 37 mounted freely on roller 32 and secured by a link 38 to a flange projecting rearwardly from an extension 39 of the channel member 14. A fixed resilient pawl 41 holds the ratchet wheel 36 against backward rotation when key 16 is released. For viewing the expiration of the webs, a small aperture is provided in the top 6 between the main writing window 7 and the side wall 2 adjacent the spindle 25.

Title: Improvements in electric spot-welding installations
IPC: B23K11/24
Filed: 1934-08-16
Abstract: 431,977. Switching systems for welding installations. SCIAKY, D., 13<bis>, Rue Charles Fourier, Paris. Aug. 16, 1934, No. 23666. Convention date, May 30. [Class 38 (iv)] In electric spot welding by A.C., a synchronously driven rotary contact is associated with the operating pedal in such a way that current flows for a definite part of a current cycle for one operation of the pedal, the system being restored to its initial condition after each flow of welding current. In the system shown in the Figure, a conducting sector on a disc d driven by the synchronous motor 100 connects the brushes d<1>, d<2> for a time interval which is a fraction of an alternation. The adjustment of the brushes determines the duration of the interval and the point in the alternation at which flow commences. The pedal f when free as shown completes a circuit through a coil e which engages contacts e<1> e<2>. If the pedal f is depressed to engage contact f<2> and initiate a welding cycle when the conducting sector is in engagement with contacts d<1>, d<2>, the coil e continues to be energized but through the contacts d<1>, d<2>, e<1>, e<2>. As soon as rotation of the disc d breaks this circuit, coil e is deenergized and contact e<1> engages contact e<3>. When contacts d<1>, d' are again connected by the conducting sector a circuit is completed through contacts d<1>, d<2> e<1>, e<3>, and coil b<1> by which switch arms band h<3> are closed and h<4> opened. The circuit through the primary a<1> of the welding transformer is thus closed until the conducting sector leaves contact d<1> when coil b<l> is de-energized, but during this welding period, a circuit is completed through pedal contacts f<1>,f<2>, coil g and contacts h<1>, h<3> whereby switches g<1>, g<3> are closed so that coil g continues to be energized through contacts g<1>, g<2>, f<2>, f, when switches b open on completion of the weld. The circuit through coil e is then completed through contacts h<4>, h<2>, g3, g<4>, so that contacts e<1>, e<2> are closed and the welding switches t cannot be closed until pedal contact is released when the normal circuit through coil e is reestablished at f, f<1>, the circuit through coil g is broken at f<2> and the system is thus ready for a fresh welding cycle. In a modification, the current in the primary of the welding transformer is led through the conducting sector of the synchronously driven disc d, the circuit being closed by a brush engaging the sector and opened by the switch b.

Title: Improvements in electric motor starting switches or circuit-breakers
IPC: H01H71/68
Filed: 1935-08-26
Abstract: 461,900. Electromagnetic switches. WEST & CO., Ltd., A., and PAVITT, F. J. Aug. 26, 1935, No. 23845. [Class 38 (v)] [Also in Group XXXII] A switch for the control of electric motors is adapted to be opened by the action of an overload winding subject to a time delay occasioned by a dashpot, both the bobbin of the overhead winding and the dashpot cylinder being formed of moulded insulating material and being detachably secured to one another to form one unit. As shown in Figs. 2 and 4, three overload windings 10. . . . . 12 are provided each wound on a body 48 of synthetic resin material, the body 48 in each case being formed with a square boss through which the attachment bolts 49 project and a downwardly-projecting screw-threaded extension on which screws the dashpot cylinder 50 also of moulded synthetic resin. The cylinder 50 has a metal lining 51 at the lower part of its interior in which normally rests a piston 52 secured to the lower end of the core 31. On moderate overloads a dished washer 53 rests lightly and permits leakage, through a hole in the washer, though with heavy overloads the washer is forced over this hole and the plunger rises at a rate determined by the piston clearance. Very severe overloads, however, raise the plunger almost instantaneously. The adjusted position of the dashpot cylinder showing the overload setting is indicated on a calibrated scale 55. The upper end of the coil is arranged to strike a tripping bar 30, Fig. 3, with a hammer blow so releasing a lever 61 pivoted at 60, the lever 61 carrying a guided contact lever 22 which is thus moved by gravity from a relatively fixed contact bar 23. This breaks the circuit of the coil 16 of the starter switch, which on de-energization breaks the main circuit. To reclose a push-button 29 is depressed which brings 2 contacts 22, 23 again into engagement and relatches the arm 61. Manual release is effected by depression of buttons 29 sufficiently to cause an insulating roller 63 to force contacts 22, 23 apart. The starter switch Fig. 5, comprises an E- shaped fixed core 33 with the winding 16 on its central limb and a spring 35 acting between the upper end of the winding and the movable E-shape core 34. To the latter is pivotally attached a synthetic resin moulding 39 carrying four bridging contacts 13, co-operating with pairs of fixed contacts on a moulding 43. The moulding 43 is carried by bars 45 sprung over projections 47 on the fixed core. Three of these sets of contacts are in the main supply leads the fourth being maintaining contacts in the circuit of coil 16.
