Title: Improvements in and relating to headlamps or auxiliary lamps for motor road vehicles
IPC: B60Q1/068
Filed: 1938-11-09
Abstract: 521,157. Vehicle lamps. PEILL, D. M., MACINTYRE, N., and WONDER LAMP & LIGHTING CO., Ltd. Nov. 9, 1938, No. 32543. [Classes 75 (ii) and 75 (iv)] In a lamp for motor vehicles two reflectors, 4, 5, fitted with separate light sources and projecting beams of different characteristics are mounted on a carrier 6 which can be turned in the lamp casing 1 by a remote control device so as to bring either reflector into the operative position, and the circuit to the light source in the operative position is completed by a make- and-break device carried by a pivot element of the carrier. The ‹carrier 6 comprises a sheetmetal stamping having cranked limbs 23, 24 of which the limb 23 carries a recessed block 25 engaged by a spring-pressed pin 29 carried by a sleeve 30 on the lamp-casing and the limb 24 carries a pivot pin 31 having its lower end engaging a cup 34 fixed to an insulator plate 35 secured to a base bracket 36 on the lamp casing. The lamp bulb 9 and reflector, 4 are secured to a bush 8 in a boss 7 welded to the carrier 6 and the lamp bulb and reflector 5 are secured to a lateral extension of the carrier 6. The conductors 4a, 5a lead from contacts fixed to insulating block 12 and engaging the bulbs in the reflectors 4, 5 to contacts 42, 41 mounted on an insulating disc 22 secured to the pivot-pin 31. By means of a Bowden cable 45 operated by a knob 49 on the vehicle steering column and anchored to the grooved periphery of the disc 22 the carrier 6 may be turned against the resistance of a spring 32 to bring either reflector into the operative position and the corresponding contact 42 or 41 into engagement with a spring contact 39 fixed to the plate 35 and having a current supply lead 40. The axis of the pivot pins 29, 31 may be inclined to the vertical and the knob 49 may carry a spring detent ball clicking into a number of recesses in the knob-socket 48 to afford a number of setting positions for the reflector 5 which preferably provides a fog-penetrating beam. For this reson the contact 41 consists of an arcuate strip. A lug 56 on the disc 22 engages the member 35 to limit the displacement of the carrier 6. To allow the movement of the reflectors the front glass consists of a cylindrical centre part 3a having a vertical axis, a partspherical lower part 3b, and a nearly flat or large radiused upper part 3c. Specifications 470,348 and 497,342 are referred to. Reference has been directed by the Comptroller to Specification 497,342.

Patent GB-328240-A (GB)
Abstract: 328,240. Gredt, P. Oct. 15, 1928. Addition to 240,165. Metallurgical. furnaces. - The reduction portion of the process of the parent Specification is effected in a superposed hearth furnace having a preheating-zone, which is kept separate from the reducing-zone by an ore seal, and is heated by spent gases from the reducing-zone. In the six hearth furnace shown the ore seal is formed between the second and third hearths so that the two top hearths form the preheating zone. Reducing gas is supplied to the remaining hearths through a preheater c and passages t1 - - t4, and the spent gases pass to a flue h and thence through passages u5, u6 to the preheating-hearths. Air for combustion is heated in the rabble shaft a, and passes to the flue g in communication with a parallel flue f, to which fresh combustible gases may be supplied. Part of the mixture passes to the preheating hearths, while the remainder serves to heat the muffle flues k beneath the hearths, the waste gases passing away through the vertical flue s, and the preheating hearths to the exhaust flue m. Gas analyzers o and pyrometers n are provided at various points of the flues so that the working of the apparatus can be controlled by manipulation of dampers. The reducing gases may pass over the hearths in series instead of in parallel, and they may be supplied from the smelting-furnace into which the reduced ore is passed. The preheating of the reducing-gas may be effected by burning a portion and mixing the products with the remainder. The necessary temperature for the reduction process may be maintained electrically.

Title: Improvements in and relating to the starting of internal combustion engines
Inventor: DOUGLAS JOHN GEORGE
IPC: F02M1/00
Filed: 1963-08-23
Abstract: 1,005,057. Lubricating. J. G. DOUGLAS. Aug. 21, 1964 [Aug. 23, 1963], No. 33453/63. Heading F2A. An engine of a motor vehicle is lubricated prior to being started, by lubricant being injected into the float-chamber of the carburetter. In an embodiment, lubricant is supplied to a float-chamber 6, Fig. 1, by means of a pump having a piston 7 urged by a spring 9 and connected by a Bowden cable 12 to a knob on the dashboard of the vehicle. The spring 9 forces a member 10 towards a screw 13, the adjustment of which varies the volume of a pump chamber 1. In operation, the cable 12 is pulled, the piston 7 is moved against the action of the spring 9 and lubricant is drawn into the chamber 1, via the inlet 2 and valve 14. Upon release of the cable, the piston, under the action of the spring, forces lubricant out of the chamber 1 and into the float-chamber 6, via a tube 4 and a valve 5. In modifications, the piston 7 is replaced by a diaphragm 15, Fig. 2; the cable 12 is replaced by a pull-rod which is secured to the armature of a solenoid; the solenoid is connected to the starter-motor circuit; and a porous-plug is inserted in the pump inlet so as to prevent repeated injections of lubricant into the float-chamber, the lubricant reservoir being located above the pump so that entry of oil is aided by gravity. In another embodiment shown in Fig. 3, the pump chamber is connected to the inlet manifold of the engine by an inlet 20. When the engine is running, the diaphragm 15 retracts and lubricant is drawn into the chamber via an inlet 21 and a valve 22. When the engine stops, the diaphragm 15 is urged by the spring 16 and lubricant is forced into the float-chamber, via a porous plug 23 and an outlet 3. Alternatively, the pump may be automatically controlled by means of a thermostat, the float in the carburetter float chamber or by means of a gravity responsive device.

A valve body 31, has a lateral inlet and outlet 37, 38, respectively, with an annular groove leading to an intermediate drain port 138 whilst a rod 34 loaded by a spring 40 passes through the body and forms an annular space 33 within a piston 32. Pressure fluid at the inlet 37 acts on the piston in opposition to the spring and unseats a piston extension from a body end cap 35 to enable the fluid to traverse the space 33, the flow rate being maintained constant by the extent to which the piston covers the drain port groove. The rod 34 is axially movable to facilitate adjustment of the loading of spring 40 and hence of the rate of flow through the valve.
