Title: Lamp shade of superimposed sections - has U-shaped sections pegged together with lamp at base
IPC: F21Y101/00
Filed: 1980-01-16
Abstract: A lamp shade is made up of roughly U-shaped pieces. These form two branches and a core. They are fitted on top of each other. The free ends of the branches are turned in the same direction and inserts are placed between them. The pieces and inserts can be of similar shape and size. They can be sized so that, from one side of the lamp shade to the other, one overlaps to the centre of the other. The lamp (34) is in the base.

Title: Radio receiver remote control - has infrared controller connected by optic fibre to receptor preventing leakage to radio signal components
Inventor: RIECHMANN WERNER
IPC: H04B10/114
Filed: 1980-06-30
Abstract: The cabinet (1) of a radio receiver has a light aperture (7) holding a lens (8) connected by an optical fibre (6) to optoelectronic components (3) inside a metal housing (2). These components form an infra-red remote control device for another member (4) connected to it by a signal line (5) also inside the housing. The second member can be a microprocessor controlled by infra-red signals, and is connected to the control device (3) by a code converter and a memory, the whole using integrated circuit technique. In another design, the infra-red control device is connected to a frequency synthesiser forming the second member. These arrangements prevent the remote control signals interfering with those of the radio receiver proper.

The third module controls the solar panels and has selecting switches and the fourth module includes relays controlling the operation of wood or coal burning appliances.
Patent FR-2462837-A1 (FR)
Inventor: LECHNER HUBERT
IPC: B06B1/06
Filed: 1980-07-23
Abstract: The ultrasound converter, which is pressure-proof, hot water resistant and insensitive to temperature changes, consists of a converter housing (1), an oscillating element (2) with a piezo disc (3), electrodes (4; 6), and a power cable (7). In the space between the floor of the housing (5) and the rear electrode (6) is an ultrasound-insulating medium, preferably a synthetic foam. The oscillating element (2) rests on a shoulder (13) of the converter housing (1), and is axially rigid and radially movable. Its outer surface is distanced from the converter housing (1), and it is sealed against the converter housing (1), and held elastically, by an elastic seal (14). Openings (16), which are permeable to water vapour, are arranged in the housing floor (5). The front electrode (4) extends to the rear face of the piezo disc (3). A plastic film or an O-ring can be used as the elastic seal (14). If the ultrasound converter is used to measure the flow rate in a pipe, the diameter of the piezo disc (3) is greater than the internal diameter of the pipe.

Title: Tyre tread bands with perforations leading to sub surface channels - for new or retread tyres with good grip in the wet
Inventor: KENNEY MICHAEL JOHN
IPC: B29D30/58
Filed: 1980-10-30
Abstract: A tyre tread takes the form of a rubber band with a smooth surface and radial openings to admit surface water to a series of channels which underly the tread. Used for suitable new tyres with integral tread beads or for retread systems. Compared with conventional treads having heavy section tread blocks separated by open, intersecting channels, the perforated tread face provides better grip on smooth wet or dry roads, suppresses aquaplaning, runs cooler and more quietly and is more wear-resistant.

Title: Digester vessel to make methane from liq. manure - has inlet-outlet pipe with branch to high pressure unblocking fluid
Inventor: CHARVET RENE ANTOINE
IPC: C12M1/107
Filed: 1981-02-10
Abstract: Vessel is connected to a service pipe, e.g. for the inlet or outlet of liq. manure recirculated via an external pump, or to discharge liq. from a constant level overflow. The service pipe is fitted with an isolating valve. Between the isolating valve and the vessel a branch pipe is let into the service pipe. The branch pipe is connected via a stop valve, with a supply of fluid under pressure e.g. high pressure water. The vessel is used for digesting liq. manure to produce methane gas etc. as it converts the waste into liq. manure. High pressure liq. can be driven through the service pipe into the vessel to clear any obstruction.

Title: Autonomous mechanical energy hydropneumatic engine
IPC: F03B17/04
Filed: 1981-02-20
Abstract: a. Autonomous mechanical energy hydropneumatic engine making use of the dynamic force resulting from the difference in density of fluids held in constant imbalance and operating according to Archimedes' principle. b. Arranged in a tank containing a liquid, it essentially comprises the mechanical members described hereafter:   1. A submerged driving wheel mounted vertically on a horizontal shaft, equipped with bellows (containing a gas) and connected together in pairs by virtue of ducts; 2. on the external portion towards the rim, each bellows will be mounted with a metal cap (or movable percussion mass); 3. inside each duct there will be placed a steel rod securely connecting together (in pairs) the movable percussion masses of the symmetrically opposed bellows;   4. on the upper portion of the caps ball stops will be mounted; 5. Finally, a slide rail in the shape of a hoop placed against the wheel will hold the bellows closed during their complete descents <<by a half-circumference of the wheel>>.   The automatic and constant transfer of gas in the low portion of the wheel gives rise, by the liquid in which it is submerged, to a permanent vertical thrust directed from bottom to top, according to Archimedes' principle. c. Device of simple and useful design for producing mechanical energy in the most varied sectors of our contemporary economy.

Title: Signalling switch e.g. for fire or end-of-travel detector - includes glass plate carrying conductive strip which is broken in emergency by spring-loaded percussive element
Inventor: STARCK CHRISTIAN
IPC: G08B25/12
Filed: 1981-06-19
Abstract: The detector may be used in a fire alarm or in other sensors in which one alarm condition is to be detected. A conductive strip (2) is applied to a plate glass (1) support which is held between two contacts (3,4) such that the conductive strip completes a circuit between two terminals (12,13). When the alarm condition occurs, the glass plate is broken, and so the circuit through the conductive strip is also broken. In an end-of-travel detector a spring loaded pin (9) is driven into the glass to break it. Since the glass in such a detector forms the base of the conductive strip, it is not easy for the detector to be activated and then returned to its normal condition as is possible with some alarms. The glass support (1) may be broken by a spring (8) and a percussion element (9) which are slidably mounted in a support which is unitary with the housing. Alternatively, a thermally-sensitive strip may be used to break the circuit when a preset temp. is reached.

Title: Mould wheel for granulating press to produce animal feed - has hardened steel cylindrical section between high tensile side cheeks
IPC: B30B11/20
Filed: 1981-07-27
Abstract: The mould wheel has a central, hollow cylindrical section between two coaxial, circular side cheeks which are flanged outward to a greater dia. than that of the cylindrical centre section. A great number of mould passages radially perforate the wall of the centre section. The mould wheel rotates at high speed about a pair of grinding rollers contained within the cylindrical section. The cylindrical section and two side cheeks are made as three separate components. The cylindrical section is made of abrasion resistant steel and the two side cheeks of steel of a higher tensile strength. Pref. each side cheek has a central bore and is thermally shrunk on to a coaxial stub of the cylindrical section and then secured with high tensile bolts. Passing axially through the side cheek. Before heating the side cheeks bore dia. is pref. less than the stub dia. by between 0.3 and 0.5 mm. The mould wheel is for a rotary granulating press to produce pellets of animal feed etc.
