Title: Benzaldehydes prepn - by base treatment of a benzyl hydroperoxide in a two-phase aq. org. mixt.
IPC: C07C45/00
Filed: 1974-11-12
Abstract: Benzaldehyde (deriv.) is prepd. by reacting an opt. substd. benzyl hydroperoxide with a base in a mixture of water and an organic hydrophobic liquid which is capable of dissolving the benzaldehyde, sepg. the organic layer, neutralising with acid, washing with water, drying, evaporating, and distilling the prodt. The prodts. are useful as starting materials for medicaments, agricultural prodts., perfumes etc. By effecting the reaction in a heterogeneous solvent system, side reactions, esp. the Cannizzaro reaction, are minimized. This gives higher yields of prodt. Suitable organic solvents include benzene, toluene, hexane, methylene chloride and anisole and the reaction is effected below 150 degrees C, perf. -20 to 100 degrees C. Suitable bases include sodium and potassium hydroxide, carbonate and bicarbonate. Pref. hydroperoxides used as starting material include benzyl, o- and p-methyl benzyl, o- and p-isopropyl benzyl, and o- and p-chlorobenzyl.

Title: Electrical synthetic plastic capacitor - has thermoplastic dielectric element fabricated by flattening layered roll of conductive and dielectric strips and heat cycling
IPC: H01G13/00
Filed: 1974-12-27
Abstract: The electrical capacitor is fabricated from a roll of strips of film layers of conductive and dielectric materials, the dielectric material being a layer of thermoplastic material. The roll of materials is flattened into elements (11) to obtain a reduced size capacitor. The flattening procedure consists of using a fixture which has a base (1), vertical columns, a platen (3), springs (8), and a rod (6) connected to a hydraulic ram. The flattened capacitors (11) between insulating plates (10, 10c, 10c, 10g) are subjected to a further flattening process by applying, simultaneously, pressure using the fixture (1) and a temperature cycle for a preset time. Flow of the plastic dielectric and adhesion of the dielectric are obtained during the temperature cycle.

Title: Vehicle trailer compressed air braking system - has pressure controller with multi circuit protection valve and high pressure vehicle reservoir
IPC: B60T13/26
Filed: 1976-03-29
Abstract: The air brake system for a tractor and trailer is designed so that on the occasion of a failure of one of the two pressure limiting valves, there is prevented the maintenance of too high a pressure in the complete operational brake installation due to the safety valve in the pressure regulator being adjusted to too high a pressure because of the high pressure in the connected low pressure valve. A supply container is provided for each operational brake circuit and a pressure limiting valve, so that at least one of these valves is connected to a control line and the shift point of the pressure limiting valve can be varied in relation to the pressure over the control line from the supply pressure used to supply the trailer brake.

Title: Lift augmenters for aircraft wings - are adjustable by jacks to continuous or slotted flap positions to vary aerodynamic characteristics
Inventor: COLE JAMES B
IPC: B64C9/08
Filed: 1976-05-13
Abstract: The lift augmenters for aircraft wings are primarily intended for STOL aircraft, esp. designs using adjustable wing edge extensions to increase lift. The trailing edge portion of the wing (10) have in their retracted position, two streamlined flaps (24, 34). One (24) pivots about a pin (22) in a bracket projecting down from the wing and the other (34) about a pin (35) partway along the supporting arm (20) of the first, so that normally extended they form a smooth continuation of the wing upper surface curve. A jack (30) between the front of the forward flap (24) and first support arm (20), in conjunction with a pivot (28) further back, allows this flap to be tilted downwards, opening slots along both its edges, altering the aerodynamic characteristics.
Patent FR-2359320-A1 (FR)
Title: Mechanically operated disc brake - has transfer member between shoes tilted by spring in rest position and retaining finger to limit tilt and define rest position
IPC: F16D55/224
Filed: 1976-07-19
Abstract: The mechanically-operated disc brake has two shoes acting against opposite sides of the rotating disc, one actuated by a lever-operated cam. The lever pivots on a transfer member movable in relation to the disc to transmit the movement to the second shoe. The transfer member has a support face bearing against one on the brake mounting, against which it is pressed by a spring acting against an opposite face. Parallel to the disc axis, the contact surface centre between the spring and the face of the member is offset in the axial direction to relation to that between member and mounting. Thus in the rest position the transfer member is subjected to a torque about an axis parallel to the diametral plane of the disc passing through the shoe centres on one side of the disc. A retaining finger on the mounting limits the amount of tilt of the member and thus defines its rest position.
Patent FR-2363670-A1 (FR)
Title: Lift erection in stair cage - using metal props to underpin flights which are independent of pylon
IPC: E04G23/00
Filed: 1976-09-03
Abstract: The procedure for erecting a lift in a stair cage having the flights independent of a pylon comprises the following stages. First the ceiling of the landing is demolished and all masonry and plaster is removed in order to lighten the load on the flights, then the flights are propped up. The stringers and but-ends of the steps are then cut out to allow passage of the lift cage and underpinning beams (12) at placed at the corners of the cage. Laminated plywood stringers (14) are fixed by eyebolts to the bearing beams (16) and bent steel elements (18) are welded on each side of the underpinning beam.

Title: Down packaging machine for pillows - has container with paddle wheel discharging material into perforated compression and filling shaft (OE 15.12.77)
IPC: B68G7/06
Filed: 1976-11-09
Abstract: The machine for filling down into packages (12) has a chamber (10) filled with the down, inside which rotates a paddle wheel (16) so that the down is pushed through an opening (20) at one end into a perforated filling shaft (38) assisted by suction. A double acting piston (34) moves down from above to compress the charge (66) inside the shaft. The action of the piston is synchronised with a slider (64) which is retracted by another piston inside an adjacent cylinder (68) to allow the charge to be pushed into a package (12) underneath. Any down remaining in the shaft after the slider has closed again is blown back again into the container. A control circuit operates the suction, blowing, filling and compressing cycle.
