Patent FR-2246106-A1 (FR)
Title: Inductor for use in linear motors - uses high conductivity end plates to reduce braking effects due to magnetic fringing
IPC: H02K41/025
Filed: 1973-09-27
Abstract: The inductor is used for electrical machines having a rectifier movement, esp. linear motors. It has the effect of reducing braking forces due to the longitudinal component of attraction exerted between one end of the inductor and its associated driving part, such forces being effected by the fringing nature of the fields. Each of the two faces at the ends of the inductor, perpendicular to the direction of movement, carry a high conductivity non-magnetic metal plate, made of copper or aluminium. The thickness of these plates is approximately equal to the depth of penetration of the flux lines and joule losses are minimised.

Title: Heating and cooling system for e.g. coffee treatment plant - has adjustable steam supply pipe to improve circulation
IPC: A23N12/10
Filed: 1974-08-14
Abstract: In an apparatus for heating, cooling and/or treating with a reagent of a granular material capable of flow and more especially for roasting coffee, cocoa or nuts, comprising a rotatably driven container having a shell, the slope of the wall increasing more steeply as the distance of the wall from the container axis increases, e.g. a paraboloid of revolution, in which the granular material is exposed to an upwardly directed treatment stream and which can be driven rotatably at a speed sufficient to transport the material over its rim by centrifugal action, as well as a cover displaced vertically from the rim of the container and having arcuate ribs on its underside for directing the flow of the material inwardly and a pipe passing centrally through the cover for the supply of the treatment stream and extending coaxially into the container generally as described in the parent application, the further improvement whereby; the position of this treatment stream supply pipe is adjustable, the lower edge of the pipe closely approaching the bottom of the container. This improves the circulation of the material being heating within the container, as well as the intensity of treatment, by reducing friction losses e.g. by impact of the material on the lower edge of the cylindrical rim of the cover. The overall height of the equipment is also reduced by modifying the product cooling equipment.

Patent FR-2253824-A1 (FR)
IPC: C11D3/02
Filed: 1974-12-27
Abstract: The viscosity of an aqueous alpha-olefin sulfonate detergent composition is reduced by treating such composition, usually at a concentration of 30 to 60%, with a viscosity reducing proportion, usually from 2 to 20%, of a water soluble inorganic halide salt, preferably sodium chloride. By reducing the viscosity, detergent compositions containing the alpha-olefin sulfonate detergent are made more readily pourable, pumpable and sprayable, facilitating their use in liquid detergents and in spray dried particulate form. Because the addition of halide salt may cause separation into different phases it is possible to increase the concentration of the alpha-olefin sulfonate by utilizing the phase  richer in content of such detergent material.

Title: Glass plates or pans for cooking - constructed in composite layers to reduce the temp. of the surface in contact with food
IPC: H05B3/74
Filed: 1975-11-04
Abstract: A plate of heat resistant glass used in a cooker or a pan is made in sections. Radiant heat is supplied below the plate and the heat passes through the glass to the top. The lower section of the glass is transparent to wavelengths between 0.7 and 5mu m. The upper section is bonded to the lower one. It is considerably thinner than the lower section. It absorbs radiation in the wavelength range 0.7-5 mu m. Used in glass plates or pans used for cooking. Heat transfer through the top section is by conduction. This lowers the temp. of the top surface and reduces burning of material in contact with it. Heat is not reflected back to its source so that a temp. regulator at the source is not heated and the heat supply is uninterrupted.

Title: Motorcycle with weight transfer compensation - has axis of swing arms arranged higher than upper run of drive chain and anti-dive brake
IPC: B62K11/04
Filed: 1976-11-10
Abstract: The motorcycle comprises a rear wheel (3) on a shaft carried by swinging arms (16) freely pivotable on separate shafts (14) carried by frame uprights (10). A suspension unit (18) is connected between each arm and a frame part, the shafts being at the same level or higher than the point where the upper run (21a) of the drive chain (21) crosses the frame uprights (10). Rear weight transfer during acceleration is thus suppressed. The shafts may be mounted in other holes (23) in the uprights (10), and the drive unit (5) is selectively connected to holes (25, 26), to maintain the required relationship. Forward weight transfer on braking is reduced by mounting the disc brake calipers (28) on an oblique frame member (12) by a horizontal transverse member supported at the rear of the torque arm (32).
