Title: Liquid-fuel burner for central heating system - has vaporized fuel entrained by combustion air in ejector into burner pipe
IPC: B01D1/00
Filed: 1973-08-07
Abstract: Liq.-fuel burner, for domestic central heating systems, evaporates the fuel with exclusion of air, to be entrained with combustion air in an ejector into the upstream end of a burner pipe. The mixt. is forwarded into the combustion space from the other end of the pipe. Preferably the pipe's thermal conductivity is such that the temp. of its inner wall is kept at 150-400 deg.C, to prevent condensation of the fuel on its inner walls. An opening in the ejector permits secondary air to be entrained by the combustion air, and can be adjusted between fully closed and open positions. Soot and noise emission ar eliminated.
Patent FR-2244244-A1 (FR)
Title: High efficiency transformer - has twin windings in primary and secondary and a bias current supply
IPC: H02K53/00
Filed: 1973-09-18
Abstract: The transformer design aims to increase the transfer efficiency to near 100%. In particular the secondary winding is arranged so that it is possible to make maximum use of the positive and negative excursions of the signal in it, cancelling to a large extent the opposition inductance and employing two separate windings to make up the secondary. Each such secondary winding includes a rectifying circuit providing a bias current such that there is a flux cancellation due to the opposing sense of the current and winding direction. The primary winding is similarly made up of two separate windings, again fed in such a sense that flux cancellation occurs and hence reduces the core hysteresis losses.

Title: Vehicle suspension with brake pressure limiter - rod system connected between wheel suspension arms actuates limiter
IPC: B60T8/18
Filed: 1973-10-12
Abstract: Independent suspension arms (2, 2b) for the rear wheels pivot about points (A, B) at their inner ends. The chassis cross member (1) above, carries a conventional brake pressure limiter (3) connected between the master cylinder and the brake actuator, with an operating button (4), underneath.

Title: Prodn. of panty hose from assembly of two leg portions - which have been turned inside out several times to shape them
IPC: D06H3/16
Filed: 1974-10-28
Abstract: Panty hose is produced by assembling together two leg portions in the region of the crutch and before assembly the leg portions are un-wrinkled by slight stretching produced by turning the leg portions inside out several times. This turning inside out is effected by introducing the leg portion into a tube of slightly greater dia. than the leg portion under the effect of a suction applied to the interior of tube, and then threading the leg portion back over the outside of the tube. The leg portions are unwrinkled but do not lose their elasticity as can happen with e.g. conventional vapour treatment processes. Unwrinkling the leg portions makes them easier to assemble.

Title: Block for solderless wire connector - contact forks bite into wires held in S-shaped grooves between insulating plates
IPC: H01R4/24
Filed: 1974-12-12
Abstract: The connector block, for the solderless connection of wires, consists of two insulating plates with elongated S-shaped grooves for the wires and enclosing the contact elements. Electrical connection is made by contact elements having the shape of forks that contact with the cores of the wires. The contact forks are located one at the centre of each S-shaped groove and inclined slightly to the axis of this central part of the S. The inclination to the central part of the S increases the biting action of the contact forks. The advantage lies in giving a rigid connection without solder.

Title: Heat insulating window frame with glass pane - for improvement of old buildings without expense and complication of double glazing
IPC: E06B3/28
Filed: 1975-02-03
Abstract: Heat-insulating window frame comprises a glass pane having a thickness of 5-8 mm. which is pref. sheathed in a U-shaped neoprene joint which may be sheathed in an Al profile over 9/10 of its height. The neoprene joint may be partially cut away in one rectangular surface which faces inwardly, over a length of approx. 30 mm. The Al profile may be cut at 45 degrees to provide a good finishing angle, and provided with one or two holes on each side just above the cutaway. Between the existing window frame and that of the invention may be interposed a flexible joint of silicone or similar matl., and the whole assembly may be fixed with screws with countersunk heads. The cutaway creates slight turbulence between the two window panes, causing a difference in temp. between the interior and exterior of the air cushion, which prevents the formation of condensation.

Title: Refractory bricks for metallurgical furnaces - shaped with male and female mating parts to prevent dislodgement
IPC: C21C5/44
Filed: 1975-03-03
Abstract: Refractory brick has protuberances and matching hollows in two rows on opposite halves of the brick, on the same surface. Two such layers of bricks can be used to line a furnace, with the protrusions in one layer mating with the hollows in the other and vice versa. The same protuberances and hollows may be formed on both opposing major surfaces when several layers of bricks are required. The bricks are used for lining Martin furnaces, electric furnaces and converters, esp. in regions where excessive wear occurs due to extreme conditions, e.g. tuyeres. They provide improved wear resistance and hence improved furnace yield.

Title: Skid prevention system for air brakes - has twin valved modulator operated by electrical relays controlled by pressure transducer
Inventor: SEKIGUCHI YUKICHI
IPC: B60T8/50
Filed: 1976-01-20
Abstract: The skid prevention system for air brakes has a modulator positioned on a compressed air line operating a valve in the line to the brakes. The modulator is controlled by an electric transducer which emits a reduced voltage when the braking pressure exceeds or falls below preset values. The modulator (6) has two valves (53, 54), the first working a relay valve (5) and the second operating a wheel mounted servo (3).

Patent FR-2341192-A1 (FR)
Title: Motor vehicle lighting control - is steering column mounted with movement to control headlight beam, trafficators and main light on-off switch
IPC: B60Q1/14
Filed: 1976-02-16
Abstract: Lever or stalk operated switch providing control of motor vehicle lighting, the lever being normally positioned immediately behind the steering wheel. The switch is intended to overcome the need for the driver to remember the switch sequence. Beam intensity is controlled by moving the lever either away from or towards the driver. An impulse in one direction changes the lights from full beam to dipped, whilst an impulse in the opposite direction changes from dipped lights to full beam. A second impulse in either direction does not effect the lights. A single larger movement will flash the headlights when they are normally off. The lights are switched off by turning an end button on the stalk through 90 deg. The shaft acts through a moving cover plate into a switch box, trafficators and main lights being activated by two sprung pawls riding over cams controlled by an inner ring carrying single cog.

Title: Cellular sheet unstacking device - has rotary brush at front of stack above which suckers are attached by supports to slide
IPC: B65G59/10
Filed: 1976-03-16
Abstract: A pile (2) of cellular sheets is stacked on a plate (3) which is gradually raised automatically by a sensor (5) operating through a slave device (6) driving a pneumatic jack (4). Above the pile of sheets are a series of suckers (8) attached by supports (10) to a slide (9) which can be displaced vertically and horizontally enabling the top sheet (1) to be picked up and removed. The suckers are manoeuvred in cooperation with a hard bristled brush (13) rotating about an axis (14) which is placed slightly above the level of the top sheet. A jet (15) of ionised air is also directed at the top of the pile, the ionisation overcoming any static electricity which might hold two sheets together.
