Title: Control arrangement for vehicle headlamps
IPC: B60Q1/06
Filed: 1973-10-11
Abstract: 1471879 Control of vehicle headlamps by DC motors LUCAS ELECTRICAL Ltd 27 Sept 1974 [11 Oct 1973 28 Nov 1973 7 Dec 1973] 47552/73 55115/73 and 56951/73 Headings H2H and H2J The headlamps (not shown) of a vehicle are moved between extended and retracted positions by respective D.C. motors 14 which are energized when the movable contact 15 of a switch 10 is changed between the position shown and the lower position, thereby switching on or off the sidelights and the main beam or dipped filaments 22 or 24 (controlled by the position of a changeover switch 11), each motor being energized by operation of a relay 12 and controlling the movable contact 27 of a changeover switch 13, whereby the latter operates to deenergize the relay 12 at or towards the end of the lamp movement and so produce short circuit braking of the motor. In a typical extending operation, movement of contact 15 to the lower position energizes the sidelights and filaments 22 or 24 and completes a circuit to relay coil 28 through members 51, 21a, 20 and 27, the relay contacts 30, 32 closing to switch on the motor which runs until it changes contact 27 from contact 20 to 16, so de-energizing coil 28 and changing contact 30 from contact 32 to 31 to short circuit the motor armature. In a retracting operation, movement of contact 15 to the upper position switches off the side and headlights and energizes the coil 28 through members 55a, 17a, 16 and 27, a similar motor operation then occurring as in the extending action. The headlamps may be extended with the contact 15 in its upper position by operation of a contact 26 to momentarily energize the main beam filaments 22, consequent current flow through a heater 52 closing contacts 54 after a time delay to energize coil 55b, change over contacts 55a and so energize the coil 28 through members 21a, 20 and 27. Switch 52, 54 has a long opening time delay whereby the lamps are not retracted immediately contact 26 is opened, to allow flashing of the lamps by several operations of the contact 26 in rapid succession. An arrangement of this type is described and claimed in Specification 1,471,652. In a modification, Fig. 2 (not shown), the circuit point 23 is connected to the line 21 through a diode (56) to enable the lamps to be extended more quickly when the contact 26 is closed.

Filed: 1968-10-18
Abstract: 1277410 Transformer arrangements MIDLAND TRANSFORMER CO Ltd 14 Jan 1970 [18 Oct 1968] 49445/68 Heading H2H An alternating current voltage regulating assembly comprises a regulating coil and two magnetically coupled windings having equal number of turns, the two windings being connected the regulating coil by two similar connecting means, the' connecting means being axialty movable along the regulating coil in such a manner that the voltages impressed on the two windings are equal, and variable whereby the output voltage from the assembly can be varied from maximum buck to maximum boost. A regulating winding 10 connected to an A.C. supply 13, 14 is provided with two contact assemblies 20, 21 and 27, 28. Two magnetically coupled windings 15, 22 are connected to the contact assemblies, the winding 15 to contacts 20, 21 and the winding 22 to contacts 27, 28. Whilst the contacts are moving along the coil 10 the movements thereof are such that the voltages impressed on the windings 15, 22 are always equal. Initially, whilst the contacts 21, 27 are moving along the coil 10 in opposite directions the contacts 20, 28 remain at the ends 11, 12 of the coil 10 respectively. When the contacts 21, 27 are at the ends 12, 11 respectively maximum voltages are impressed on the windings 15, 22. As the contacts 21, 27 move towards the ends 11, 12 less and less voltage is impressed on the windings 15, 22 until with the contacts 21, 27 at the ends 11, 12 no voltage is impressed on either winding 15, 22. Contacts 20, 28 are then moved towards the ends 12, 11 respectively of the coil 10 thereby impressing greater and greater voltages on the windings 15, 22 of opposite polarities to the voltages impressed by movement of the contacts 21, 27 until finally maximum voltages are again impressed on windings 15, 22. Thus movement of the contacts produces maximum voltages of one polarity to maximum voltages of the other polarity in the windings 15, 22. The output of the assembly may be taken from the winding 22 or from a further; secondary winding associated with the windings 15, 22.

Abstract: 1,210,376. Cutting tubes. R. G. STEWART-PRINCE. (Aircraft-Marine Products (Australia) Pty. Ltd). 1 Nov., 1967, No. 49543/67. Heading B4B. [Also in Divisions F2 and H2] A continuous strip ST of PVC insulating sleeves SV, which are connected together in axial alignment by slugs SL formed by cutting slots S in a tube of insulating material, is fed step by step by a reciprocating feed finger 114 to a crimping and shearing device which crimps the leading sleeve SV<SP>1</SP> around an inserted electrical connector C and simultaneously shears through the slug between this and the following sleeve SV<SP>11</SP>, after which the process is repeated, each connector C, which has been previously crimped on to a wire W in another machine (not shown), being inserted by an operator who then presses a pedal to energize a " one-shot " clutch which causes a ram 70 to move through one cycle from the top dead centre position shown to operate the device. The ram 70 carries sleeve crimping dies 72, 74, which co-operate with anvils 118, 120, respectively, and a shearing blade 78 is slidably mounted on a holder 76 carried by the ram. The movement of the shearing blade is so controlled, by mechanism including a two-armed latching lever 90 which is engageable with an adjustable fixed abutment 98 and also engages a pin 88 carried by the shearing blade, that during upward movement of the ram, following a crimping and shearing operation which takes place during the downward stroke of the ram, the blade 78 is first lifted clear of the strip ST, to allow the next sleeve to be fed on to the anvils 118, 120, and is then allowed to drop into the next slot S where it acts as a stop to limit insertion of the next connector C by the operator, thus ensuring consistency of the finished insulated connectors. The latching lever fulfils the above function by being biased against the pin through the action of a spring 96 and being pivoted at 92 to a projection 94 of the holder 76, the spring causing the upper end of the shearing blade to remain at its highest point relative to the ram (Fig. 4B, not shown) excepting in the top dead centre position (shown) where the lever 90 has engaged the abutment 98, causing the lever to rock anti-clockwise and thus allow the shearing blade to drop into the slot S. A friction pad 110 is urged by springs 112 against the top of the strip ST to prevent undesired movement of the latter between feeding strokes of the finger 114.
