Title: Filter unit for vacuum cleaners with disposable filter bag - has hinged lid and separate frame attached to dust chamber lid
IPC: A47L9/14
Filed: 1974-09-13
Abstract: The vacuum cleaner filter unit comprises a material bag with a fixed frame and lid and is fastened to the inside of the lid of the dust collection chamber of the cleaner, pref. by clip fasteners. The lid of the filter unit is fastened to the dust chamber lid by hinges separately from the frame so that to replace the filter bag, the frame is moved away from the chamber lid so that the filter lid automatically folds open so that the bag can be thrown from the filter unit straight into the dustbin without actually having to handle it. Since the filter unit is attached to the lid of the dust chamber it is only necessary to align the latter on the vacuum cleaner to ensure perfect positioning of the unit relative to the suction opening.
Patent FR-2244631-A1 (FR)
Title: Transfer sheet with symbols attached by film - which breaks around each symbol under pressure applied by pencil
IPC: B44C1/17
Filed: 1974-09-24
Abstract: A transfer material comprises a transparent or translucent sheet with a peeling coating on one face; the symbols or letters are attached to this coating and are themselves coated with pressure-sensitive adhesive. To effect the transfer, the back of the sheet is rubbed with a pencil etc., thus causing the peeling layer to break around the edge of each symbol or letter and to release it from the transfer sheet. The letters become transferred to the receiving sheet, taking the underside of the peeling layer with them. The letters are pref. of an adhesive printer's ink contg. dye or pigment; the peeling layer may also contain dye or pigment. The letters have a tensile strength pref. at least equal to that of the peeling layers. Pref. materials for the transfer sheet are polystyrene, polystyrene-butadiene, or polyethylene terephthalate. The brittleness of the rupture of the peeling layers leads to instant transfer of the symbols.

Title: Self-loading bale trailer - has intake elevator to conveyor with upper and lower parts forming stacking space
IPC: A01D90/08
Filed: 1974-09-27
Abstract: The trailer consists of uprights supporting lateral guides which form a sinous channels in which the bales are stacked. The channel entrance has an elevator and the trailer floor consists of two bars between which a conveyor chain operates. After the bale has been lifted by the elevator it strikes a plate which causes dog-clutches to engage. As a result a wheel turns and drives the chain which conveys the bale into the channel. As soon as the bale has passed the plate the mechanism stops until activated by another bale. When the first bale reaches a conveyor wheel immediately above the bale entering the trailer the chain is activated and the wheel places the first bale on top of the last bale and so on until the trailer is full.

Title: Transporter for smooth transit of bedridden patients - employs individual stretchers picked up hydraulically by a special push-trolley
IPC: A61G1/003
Filed: 1975-03-27
Abstract: The system is based on the principle that a patient is placed on a stretcher before leaving his ward and stays on it while in the operating theatre and again back in the ward until it is safe to shift him from it. The stretchers would be moved about the hospital on a trolley whose U-shaped base fits around a bed. The trolley bears a pair of hand-pump-operated hydraulic cylinders whose pistons raise and lower a frame over which the stretcher is hooked for transport and from which it is unhooked at the end of the journey so as to free the trolley for further use. The frame can be turned from its horizontal operating position to save space when the trolley is parked.

Title: Precision forged bolts of steel or titanium alloys - where accurately turned blanks are hot forged to exact dimensions
IPC: B21H3/06
Filed: 1975-07-30
Abstract: Shafts, screws, bolts and similar metal parts are mass produced with high mechanical strength and very close dimensional tolerances, by forging round blanks obtd. by drawing and grinding. The blanks are coated with a lubricant resistant to heat and forging stress; and are then heated and precision-forged to obtain dimensional tolerances of 1/100th of a mm. Heating prior to forging is pref. below the transformation temp. of the metal or alloy used. The blanks are pref. first treated mechanically by shot blasting or descaling, and the lubricant is pref. a solid suspended in a polymerisable resin and sprayed onto the blank followed by polymerisation. Forging pref. produces both a head on the blank and a shank dia. suitable for thread formation; the forging is heat treated and cold thread-rolled. The forging process is used to mfr. e.g. Ti alloy parts for the aeronautical industry, where very accurate dimensions are required.

Title: Shock absorber and antivibration mounting - comprises knitted metal wire body with inner ring of elastomer material
Inventor: ROBINOT-BERTRAND MARCEL
IPC: F16F1/362
Filed: 1975-12-16
Abstract: A shock absorber and anti-vibration mounting is formed from an outer ring (1) of knitted metal wire with an inner ring (2) of an elastomeric material. The elastomeric ring (2) is attached to the metal wire (1) by vulcanisation. This combination of metal wire and elastomer allows the mounting to be bonded to the surface of the equipment which it supports. The inner ring of elastomer (2) is not large enough to affect the anti-vibration or shock absorbing characteristics of the mounting. Other designs of mounting have a ring of elastomer outside the ring of knitted metal wire and another design covers the wire with a layer of elastomer.

Title: Controlled atmos. for heat treatment furnaces - using mixt. of nitrogen and natural gas, suitable for annealing cold rolled steel sheet
IPC: C21D1/76
Filed: 1976-08-02
Abstract: Protective gas is prepd. for use as a controlled atmos. in heat treatment furnaces. The gas is a mixt. of N2 with 3-25% natural gas, where both gases have the same dew point of ca. -40 degrees C. The two gases are mixed in a cylindrical expansion chamber, fitted at one end with a side inlet for N2, and a perforated inlet pipe extending along the axis of the chamber and supplying the natural gas. The other end of the chamber has an axial outlet for the gas mixt. Used esp. during the annealing of coils of thin cold-rolled sheet made of extra-mild steel, using, e.g. a bell-type furnace. Avoids use of coke oven gas, which has a variable compsn.; shortens total cycle time; and improves the surface as compared with when coke oven gas is used.

Title: Bakery proving cabinet for controlled fermentation - by adjusting temp. of shelves through which heat transfer fluid is pumped
IPC: F25D25/02
Filed: 1976-07-29
Abstract: The cabinet contains horizontal shelves on which the dough pieces are supported while the interior of the cabinet can be cooled and heated by circulation of a heat transfer fluid. The temp. of the fluid is regulated in a heat exchange unit outside the proving chamber. Each of the horizontal shelves is made as a heat exchanger plate supported by two vertical side members of the cabinet. Each side member serves as a flow manifold, one supplying heat transfer fluid to the shelves while the other collects the fluid for recycling via the external, heat exchange unit. The shelves are pref. adjustable in height on the side members, flexible hose leads being used to connect the shelves to the flow manifolds of the side members. There is no contact between the prod. and the heat transfer fluid. This avoids the premature superficial crusting, produced by air circulation temp. control, which can impede subsequent fermentation and cooking. The shelf spacing is readily adjustable.
