Title: Parking brake for disc brake assembly - overcomes necessity for mechanical application when fluid operation is used
Inventor: GARDNER RICHARD HUBERT
IPC: B60T1/06
Filed: 1974-08-05

Title: Enamelling ferrous articles by local surface heating - using radiant heaters in a tunnel furnace
Inventor: BALLERINI CHARLES
IPC: C04B41/86
Filed: 1975-01-29
Abstract: Articles are enamelled by a process in which the heating is effected for a short duration solely on the surface where the enamel is to be fused to it, while the bodies of the articles are not heated throughout, by means of radiant heat supplied from a series of radiant panel heaters placed at an adjustable distance from the articles, which are carried past the heaters at an adjustable speed. The temp. of the surface is heated to 980-1020 degrees C and the heating effect penetrates to a depth of 0.5-2 mm. The heating costs are reduced. Process is readily adjustable according to the size and type of the articles to be enamelled, hence the need for several different sets of enamel heating plant is avoided.

Title: Insulation filled hollow brick - has rigid foam injected on endless belt and planed off by mill
IPC: B28B11/04
Filed: 1975-05-12
Abstract: Masonry blocks (7) emerging from their drying chamber on an endless belt (6) are conveyed so that the cavities in them pass under dispensers (8, 9) filling the cavities with liquid which hardens into phenolic, polyurethane or urea-formaldehyde foam. The endless belt (6) conveys the blocks (10), when filled, underneath a second endless belt (11). The distance between the lower surface (12) of this endless belt (11) and the upper surface (13) of the planks (18) on which the blocks rest is somewhat less than the height of the blocks (10). The blocks (10) then pass underneath a mill (17) which planes their top surface, removing surplus foam and giving each block a predetermined size. The endless belts are made of, or covered with, material which does not stick to the foam constituents. The speed of the two belts is synchronized.
Patent FR-2310889-A1 (FR)
Title: Decorative panel production process - deposits coloured liquid and applies material to alter distribution before drying
IPC: B44C5/04
Filed: 1975-05-14
Abstract: The decorative panel production process consists in depositing on one of the faces of a flat support which is at least partly transparent, a layer of coloured liquid. Materials are then applied locally to this liquid to alter its distribution, after which the whole is dried. The material used can be in liquid of powder form and coloured or not, driving the coloured liquid aside by the action of the interfacial tensions occurring between them. It can be applied drop by drop as a liquid, or sprayed on by aerosol can. Alternatively, sheets of absorbent material can be used.
Patent FR-2311912-A1 (FR)
Title: Electrically operated door lock - has electromagnetic armature and sprung catch which releases automatically when current is discontinued
IPC: E05B47/06
Filed: 1975-05-22
Abstract: The electric door lock contains a softly sprung bolt which engages in the door frame rebate. A constant electric current through contacts to an armature pulls in a soft iron core which has an angled extension with a simple catch. When the current flows, the catch holds a plunger out against a strong spring. The plunger has a lip which engages in a corresponding lip on the bolt, and allows the bolt to travel, under the force of the weak spring, into the locking position. Discontinuation of the current releases the catch and plunger which retracts the bolt.

Title: Disc break pad wear indicator - has insulated wire mounted in synthetic material block and projecting into pad recess
IPC: F16D66/02
Filed: 1975-10-07
Abstract: The sensor indicates when the wear of the braking pads of a disc brake has reached an unacceptable level. The insulated sensor wire (5) is mounted in a block of synthetic material (6) resistant to high temperature, which is a snap fit in a hole in the brake pad support plate (2). The wire then projects into a recess (4) cut in the brake pad. When the pad wears down, the wire makes contact with the brake disc and completes an electrical circuit to an indicator. This form of construction allows the production of standard brake pads which may be used whether the vehicle is fitted with an indicator or not.
