Title: Method of forming steel window winding pinion - involves removing annulus to leave eccentric axial tooth
IPC: B23P13/00
Filed: 1973-12-20
Abstract: The billet is cut off the bar and preformed to give the necessary blank for further operations. This blank is then either cold formed or hot forged in a press to give a shape which is suitable for finish machining. This shape has the eccentric mass (13) forming part of a ring (12) or other body of metal, this being done to improve the flow of the material. Other symmetrical sections (16, 17) are finish formed. The part is finally machined on a lathe to remove the rings (12) leaving the eccentric mass (13) in the required form. This operation reduces the diameter of the part (D1, D2).

The lacquer films are hard, elastic, can be produced in pale or pure white shades and have excellent colour constancy. They are resistant to acids, alkalis, oxidising agents and org. solvents and give a satisfactory surface, with no tendency to run off and form pits during application or baking.
Patent FR-2263141-A1 (FR)
Title: Electric power assisted vehicle steering system - has starter motor also used for auxiliary power steering source
IPC: B62D6/10
Filed: 1974-03-04
Abstract: A power steering system for a vehicle employs the starter motor also as the electric motor for bringing into engagement the auxiliary drive for the steering column. The steering column incorporates a necked portion, enclosed by an open end sleeve, and a pair of blades locate in slots in the sleeve, to indicate the torsion in the steering column during steering. This torsion and its direction are converted into signals fed to an electronic control circuit and the control signals from the circuit are used to actuate a clutch at the output of the starter motor interconnected with another clutch at the gearing located on the steering axle. Thus the starter motor brings into action the auxiliary drive, controlled by the electronic unit each time the steering wheel is turned.

Title: Window panel actuator for motor vehicles - has weight balancing spring connected to window panel lifting arm
IPC: E05F11/44
Filed: 1975-01-17
Abstract: The window panel of the motor vehicle has an actuating, rotating lifting arm. The arm is coupled to springs which counterbalance the weight of the panel. A helical spring acts on the connecting lever which rotates about a pivot which is fixed relative to the pivoting axis of a lifting arm. The connecting lever free end is coupled to the lifting arm by a pivoted link. The lifting arm is actuated by a gear drive and an actuating handle. A flat spiral spring can be used for counterbalancing instead of a helical tension spring but a helical spring facilitates construction of efficient lifting mechanisms for the window panels because the free end of this type of spring can be readily anchored.

The upper surface of the reinforcing layer is flush with the upper layer of the sole, while at any point it is thinner than the sole.
Patent FR-2308075-A1 (FR)
Title: Heat exchanger for fluids - with primary fluid flowing over heat transfer surfaces, then entraining secondary fluid
IPC: F28F1/14
Filed: 1975-04-14
Abstract: A heat exchanger, for heating or cooling fluids, incorporates a number of parallel elements which are good conductors of heat, and which are held in a transverse support, so that thre is a narrow gap between neighbouring elements. Each element has a convex part on one side and is fitted with a soruce of heat which may ben an electrical resistance or a tube carrying a hot fluid, or a source of cold, e.g., a tube carrying a cold fluid. A primary fluid under pressure, on one side of the exchanger flows over the elements and through the gaps, and mixes with a secondary fluid on the other side, entraining it and forming a combined stream. In alternative forms, the elements themselves may constitute the source of heat or cold, or the exchanger may be a perforated sheet, the holes forming the parallel elements and the gaps, the heat sources being fixed on to pieces cut and bent inwards. The flow of primary fluid under pressure, on one side of the exchanger allows a large flow of secondary fluid on the other side, so that only a small fan or pump is needed, compared with one which would be required for the whole flow. For a given duty, therefore, the space occupied is much less than with existing exchangers. In addn. the transfer of heat to the primary fluid is uniform.

Title: Shaft centre grinding machine - advances angled grinding cone into axial end of rotating shaft which spans discs supports
IPC: B24B5/24
Filed: 1975-06-19
Abstract: The machine grinds centre markings onto the axial extremities of an elongated cylindrical workpiece (7) which has been produced by a centreless process.

Patent FR-2312484-A1 (FR)
Title: Oppenauer oxidn. of allyl and benzyl alcohols - using furfural as hydrogen acceptor
Inventor: EHMANN WILLIAM JAROLD
IPC: C07C67/00
Filed: 1975-12-24
Abstract: The Oppenauer oxidn. of (a) primary allyl alcohols which are 2-substd. by a hydrocarbyl gp. and in which the allylic double bond is non-cyclic, exocyclic or endocyclic, (b) primary benzyl alcohols and (c) 3,3-disubstd. allyl alcohols, is carried out in the presence of an Oppenauer catalyst and furfural as H acceptor, to give the corresp. aldehyde as prod. and furfuryl alcohol as by-prod. The process is esp. useful for oxidising geraniol and nerol to citral, which is useful as a synthetic flavour and perfume and as an inter. for pseudoionone, which in turn is an intermediate for vitamin E and for alpha-and beta-ionone (vitamin A inters.). The use of furfural as H acceptor eliminates the aldol condensation side-reaction association with the use of acetone, and gives high yields (e.g., 94-100% for citral); furfuryl alcohol is a valuable by-prod.
