Title: Light axis adjusting system for motor vehicle
IPC: B60Q1/115
Filed: 1973-10-30
Abstract: 1421070 Adjusting vehicle headlamps NISSAN MOTOR CO Ltd 30 Oct 1973 [2 Nov 1972 2 March 1973] 50417/73 Heading F4R [Also in Division G3] In a system for adjusting the axis of a vehicle headlamp in response to the difference between signals representative of the actual angular position and of the distance between the chassis and a wheel shaft, a detector for the latter is energized only when side lamps and handbrake are on and the adjustment is made when said detector is de-energized. The object is to prevent wear due to unnessary use in daytime or when the vehicle is in motion. The system illustrated operates as follows. Closure of sidelamp 51 and handbrake 52 switches energizes a relay 53 causing a motor 33 to drive a chassis mounted feeler arm down against a spring to contact the wheel shaft, the motion being followed by a potentiometer slider 39. The motor is de-energized by a limit switch 62. The voltage on 39 is compared, by transistors T1, T2 with that on a similar potentiometer, whose slider 27 is positioned by the headlamp actuator. If the difference exceeds a threshold it energizes a relay 74, via transistors T4 ... T6, whose contacts energize an actuator drive motor 21. However, these transistors are inhibited by conduction of a further transistor T3 until the detector motor limit switch 62 is opened. To prevent spurious operation caused by lifting of the vehicle body when the accelerator is depressed the control circuits are de-energized by opening of an accelerator switch 67. Constructional details of the actuator and the detector are given (Figs. 2, and 3, not shown).

Abstract: 1,168,272. Multiple chimneys. L. J. BLACKBURN. 14 Feb., 1968 [15 Nov., 1966], No. 51104/66. Heading F4J. A multiple stack is divided segmentally into the multiflues by internal partitions 6, which are accommodated in expansion joints enabling sliding movement relative to the stack when said partitions expand and contract. As shown, the multiflue stack, which has an outer wall 5 with an internal refractory lining 7 with wire mesh reinforcement 8, is divided into three flues formed by the partitions 6, each partition having a sheet-metal core 9 and a series of transverse ribs 10 round which a wire mesh cage 11 is supported. The uncoated edges of the metal core 9 locate the partitions in channel-shaped guides 13, 14 to form the expansion joints, asbestos packing 15 being inserted between the guides and the edges. The partitions can be made up of a number of sections arranged vertically one above the other (see Fig. 2). If the stack is to taper from top to bottom, the outer guides 14 are supported on ribs (20, Fig. 3) which project inwardly of the outer wall 5 to a constantly increasing extent from top to bottom of the stack.

A foamed article, e.g. a doll's body, is produced from a plastic composition which is gellable, curable and foamable when heated, by initially distributing the composition over the surface of a closed mould cavity and gelling it thereon, curing and foaming the composition, whilst venting the cavity, by submerging the mould in an appropriately heated liquid medium. The latter may be glycerine to enable the operator to terminate the process when the mould vents are seen to be filled with extruding mould material. The composition may be placed in a plurality of moulds located in an oven and rotated about two axes at right-angles whereby the composition is spread over the mould cavities and gelled; the moulds are then removed from the oven and submerged in a bath of heated liquid. Alternatively the distribution and gelling of the composition within the cavities may also be effected with the moulds submerged in the heated liquid bath.

Abstract: 1,086,439. Rolling mills. HITACHI Ltd. Dec. 9, 1965 [Dec. 16, 1964], No. 52350/65. Heading B3M. In a rolling mill comprising work rolls 6, 7, and back-up rolls 3, 5, both ends of the rolls can be screwed down simultaneously by an hydraulic pressure supplied by the same hydraulic line, and a pressure means is provided for balancing the back up rolls, so that the screwdown pressure of the operating side, and driving side, of the mill can be adjusted independently. The operating side A, and the driving side B, of the mill have hydraulic pistons 8 between their chocks 2, 4, and hydraulic pistons 10 abutting the lower chocks. To increase the rolling pressure on both sides by an equal amount, oil is taken from a tank 23 by a pump 12 through an open valve 19, to pistons 10. To reduce the pressure on both sides, valve 20 is opened to discharge the oil to tank 23. To increase the pressure on one side only (say at side B), pistons 8 on side A are open to discharge through tube 22 by opening valve 18. To reduce pressure on one side only, valve 17 is opened with all other valves closed, and oil is supplied to pistons 8 from tank 23.
