Title: Hygienic modification of drink dispenser - eliminates contact on glass rim using sideways pressure on bar
IPC: B67D3/02
Filed: 1973-06-21
Abstract: The conventional bartenders drink dispenser for gin etc. has an upside down container with a control valve at the bottom operated by an upward pressure by the rim of a glass on rods either side of the delivery nozzle. The new apparatus has the control operated by a sideways pressure by hand or glass on a horizontal bar which passes the motion via a link (8) pivoted at a clamp (5) encircling the top of the container to another arm (12) resulting in a vertical movement which is applied to the conventional cross-arm control bars. The invention can thus be applied to existing dispensers to improve the hygiene.

Title: Annular flow fluid control valve - has sliding cylindrical valve element sealing on central plug
IPC: F16K1/12
Filed: 1973-12-20
Abstract: A streamline central body of revolution (20) is supported by radial ribs (19) from one portion (18) of the outer case, which is bolted (13) to the other portion (25), leaving an annular passage (23) for the fluid. A cylindrical piece (24) having a flange (27) at one end slides in an annular slot between the two portions of the housing and when the valve is closed, is forced out by the spring (17) until the end (34) seals against the central body. Operating fluid pressure applied at an inlet (29) causes the valve to open and seals (30, 31, 31, 33) prevent leakage. The main fluid passage shape and cylindrical valve combine to give low operating force requirements, manual combine to give low operating the complexities of double acting jacks are avoided.

Patent FR-2299594-A1 (FR)
Title: Sludge burning process - passes combustion gases from reactor to pre-drying and after-burner chambers
IPC: F23G5/30
Filed: 1975-01-30
Abstract: Industrial and sewage sludge is burnt in a reactor with a fluidised bed. Part of the combustion gases emerging from the reactor pass into a pre-drying chamber so as to evaporate part of the moisture from the sludge, while another part flows into an after-burner chamber in order to complete burning of the combustible ingredients of the gases. The gases emerging from these chambers are then reunited. Gas speed through the after-burner chamber can be higher than through the reactor combustion chamber. Some of the gases from the pre-drying chamber can be passed either to the inlet or the outlet of the after-burner chamber.
Patent FR-2266989-A1 (FR)
Title: Radio relay system - method has receivers monitoring without available equipment reserves
IPC: H04B1/60
Filed: 1975-03-05
Abstract: The system is intended for digital signals transmission. When the receiver output signal disappears, a signal modulated with rectangular pulses is automatically applied to the receiver input, or to another input loosely coupled with the former. Its carrier frequency lies within the receiver range. It is automatically tested to ascertain if this signal appears at the receiver output, and it it does, the receiver is pronounced to be in order, and faulty if it does not. In this case the test signal is disconnected after a specified time. Alternatively the test signal is in the receiver i.f. range and is applied to the i.f. amplifier input, or a loosely coupled input. Correct operation of the mixer stage is tested by other means.
Patent FR-2305313-A1 (FR)
Title: Automatic transmission vehicle engine braking system - has relay closed to cause gear change on brake pedal application
IPC: B60W10/10
Filed: 1975-03-26
Abstract: The mechanism fits onto the automatic gearbox of a motor vehicle, and automatically controls the engine braking effect while mechanical braking is taking place. The brake pedal operates circuits controlling the gearbox, causing changing down of gears. Releasing the accelerator closes the main circuit contact switch, and subsequent braking also closes a relay connected with the brake pedal. The circuit supplying this relay includes a series switch connected to the selector lever. This only opens when the lever is placed in "low", and then stops the mechanism functioning. The brake control circuit can be electronic, electric or hydraulic.

Title: Strip blind with end guides and draw member - has strips which swivel without vertical movement of bottom strip
IPC: E06B9/32
Filed: 1976-04-08
Abstract: A pull-up blind comprises strips or lamellae connected together by spacers and guided vertically by guide pivots (2) at the ends, and a fixed stop which defines the lowermost end position of the lamellae is associated with the bottom strip (1). A swivel member coupled to the pivot of the bottom strip, forming part of the displacement mechanism for swivelling the strips can be moved by the entrainment member (7) which is fixed to the draw member (6) and also forms part of the adjustment mechanism vertically from the uppermost raised position to the bottom lowered position of the bottom strip. The swivel member can also be moved during a subsequent displacement with a corresponding swivel movement of the strips with a horizontal component. The strips can be swivelled without moving vertically and the spacers between the strips can be formed as parallel guide members so that swivelling the bottom strip causes all the other strips to swivel.
