Title: Voltage regulator for AC output from vehicle alternator - uses alternator output signal to provide control pulses for linkage to carburettor valve on motoring engine
IPC: H02P9/04
Filed: 1981-10-23
Abstract: The drives an alternator through a coupling unit. This enables a mechanical, hydraulic or electrical control signal to be applied. A transformer at the alternator output provides a low voltage output for input to a comparator. This compares the voltage with a demand voltage to generate an error signal which is applied to an electronic circuit to provide two error signals. These are transmitted in turn to a control circuit which converts them into mechanical drive pulses. These pulses are applied to the control linkage which operates the butterfly valve in the engine carburettor. This adjusts the engine speed to adjust the alternator output.

Title: Friction drive for spray cleaning machine work table - unaffected by corrosive liq. and lack of work table planarity
IPC: C23G3/00
Filed: 1981-12-02
Abstract: The cleaning machine has a chamber enclosing a work table which can freely rotate on a fixed vertical arbor. A wheel is biased against a peripheral bearing surface on the underside of the table and is driven by a horizontal drive shaft which passes through a sealed bearing mounted in the side wall of the chamber. The machine is useful for cleaning components during assembly as well as for chemically treating components or decontaminating them after exposure to radioactive elements. The drive is unaffected by corrosive liq. environments in the chamber, does not require lubrication and takes up any play when the work table is not perfectly flat.

Title: Machine to mould and bake food paste prods. esp. eucharistic bread - has multi:mould turntable for automatic mould loading and emptying
IPC: A21B5/02
Filed: 1982-02-08
Abstract: Machine for moulding and baking prods. made of food paste, esp. dough comprises a horizontal, power-driven turntable. A set of cooking moulds is fixed to the turntable. The moulds are regularly spaced around a pitch circle coaxial with the turntable. Each mould comprises top and bottom plates hinged together so as to open towards the circumferential edge of the turntable. The machine comprises a mechanism for automatically opening and closing each mould in turn as well as a synchronised distributor to load a measure of paste into an open mould. Mould opening is pref. effected by a lifting cam engaging a follower roller on the top plate of each mould in turn.

Title: Flow regulator for air conditioning system - uses flexible blades to form pressure chamber walls which expand to restrict air flow channels
IPC: F24F11/75
Filed: 1982-05-28
Abstract: The centre part of a regulator (2) comprises two walls (4) extending lengthways and two cross walls (5) to form a rectangular air duct (1). The walls are attached to a front wall (6) in the form of a disc. This is fixed to an external cylindrical skirt (6a). At the rear of the front wall are two U shaped cross members (7) whose blades define a housing (8) for two flexible blade members in the regulator. These are housed at the rear by a rear U shaped cross member (9) so that the flexible blades form a pressure chamber (12) with upper (13) and lower (14) regulation channels. Air entering the chamber causes the flexible blades to deform depending on pressures in the channels to reduce the cross section of the regulated channels. Protruding flanges (17) on the lengthways walls limit movement of the flexible blades.

Title: Moulds erected in situ for the production of thermit welds.
Inventor: AUDEMAR LUCIEN
IPC: B23K23/00
Filed: 1982-09-24
Abstract: This invention provides, without particular precautions, centering and accurate sizing of the insert, ensuring correct preheating, elimination of the pattern, of its extraction and moulding machines usually used in thermit welding. It is characterised by the insertion, between the ends of rails or of bars, of a form 5 made from combustible material of thickness calibrated as a function of the sections to be welded. After filling the mould in the casing 6, this form burns during the preheating, thereby releasing the space reserved for the filler metal. It is beneficial in its application in the case of "connectors" for bars or for rails of unequal wear or cross-sections where, on account of the small number of identical welds, the unit cost of a conventional weld would support the excessively high pattern expenses. The reliability of the connection is increased as a result of correct preheating.
