Title: Winding mechanism for roller blind - has suspended roller and cable pulley with motor and engagement lever
IPC: G03B21/58
Filed: 1975-09-17
Abstract: The winding mechanism for flexible coiled material (2) consists of a roller (3) driven by an electric reduction motor (4) with its stator (5) coupled to the roller (3), and the rotor shaft (6) engaged by a lever (7). The opposite end of the lever has a pulley (9) mounted on a side arm (8), and guiding a cable (10) which is wound around the roller (3). The pulley and roller rotate in the same direction, and one pulley turn corresponds to a circumferential displacement equal to the roller diameter (or pulley circumference). Both the cable end and the upper edge of the suspended material roll are attached to fixed bars (1) at the same level.

Title: Aerated surfactant soln. for flushing filter beds - using polymeric electrolytes to emulsify residual oil and grease
Inventor: CORDIER MICHEL
IPC: B01D11/02
Filed: 1975-09-24
Abstract: High-mol. wt. cationic polyelectrolytes are added to water for cleaning filters contaminated with oil. The water is aerated by air injection as it enters the filter. The process is used for removing residual oils or greases from filter beds of gravel, fine sand, etc. esp. for recovery and re-use of industrial cooling or wash liquors. The flotation/emulsification effects of using an aerated surfactant soln. followed by a water rinse reduces the total vol. of water reqd. for cleaning a filter by a factor of 1/2 to 1/4. The emulsified oil, etc. settles rapidly (20m/h) from the aq. layer, allowing the latter to be re-used merely by making up the electrolyte content.

Title: Millimeter wavelength NPP avalanche diode - has specified tapering structure with abrupt N positive to P transition
Inventor: CACHIER GERARD
IPC: H01L23/36
Filed: 1975-12-23
Abstract: The millimeter-wave N+PP+ avalanche diode consists of a p-type layer formed epitaxially on an n+ silicon substrate and then doped p+ by diffusion, epitaxy or ion implantation. The earth electrode (22) is applied to the p+ layer and the structure is mounted by this electrode onto a copper base (4) via a gold layer (3). The structure is then chemically etched into a shape which tapers towards the electrode (21) of the n+ substrate. The advantages of this design lie in its allowing the diameter of the diode to be monitored by a microscope and in the transition between n+ and p being very abrupt -- thereby allowing the frequency to be selected relatively easily.
Patent FR-2337285-A1 (FR)
Title: Ball screw mechanism for operating disc brake - has ball travel limited by pins in nut with spring to prevent travel under no load operation
Inventor: MEYER GEORGES CHARLES
IPC: F16D65/14
Filed: 1975-12-31
Abstract: The shaft (2) is provided with a screw thread (4) to suit the balls (6) which roll in the grooves (5) in the nut (3). Pins (9a, b) in the nut (3) limit the travel of the balls. A relatively long compression spring is fitted between the pin (9a) and the balls (6). The spring force prevents the balls (6) rolling in the grooves (5) unless there is some resistance to the axial movement of the nut (3). The total travel of the balls (6) is thus reduced so that there is no need for a ball return groove in the nut (3).

Title: Camping gas stove with frame mounted burner - has two separate gas supply controls for minimum and maximum gas supply
Inventor: LAMBERT JACQUES
IPC: F23D14/28
Filed: 1976-02-04

These valves are connected to a compressed gas container or similar gas supply and are each controlled by an independent control member (48, 60). In this way the gas ring can be fed with max. supply for boiling etc. or with min. supply for simmering etc. and in both cases there is no danger of the flame being extinguished. The valves can be mounted in a common valve member (19) which has a single gas outlet in the direction of the burner (11) as well as a single gas inlet (20).

Title: Decorative films or sheets with embossed patterns - by pressing on resin filled moulds in high frequency field
IPC: B44C1/20
Filed: 1976-06-03
Abstract: A decorative film, sheet or plate with relatively narrow, raised ornamentations of synthetic resin bonded to its surface, has no cavities in the joint area between the ornamentation and the substrate.

Patent FR-2351177-A1 (FR)
IPC: C01F7/066
Filed: 1977-05-06
Abstract: The aqueous waste sludge suspension is treated at 20-80 DEG C and pH values between 4 and 13, preferably from pH 6-7, of 1.0-3.0. As a result of the chlorination, chromium is converted into the hexavalent form. Copper, zinc and nickel are present as dissolved sulphates and interfering components, such as calcium sulphate, iron sulphate and silica, are present as insoluble residues. After filtration, the chromium is first separated off from the solution in a fixed-bed anion exchanger. The copper is separated off from the remaining solution by liquid-liquid extraction with hydroxyphenone oxime diluted with petroleum as the extractant and then the zinc with di-(2-ethylhexyl) phosphate diluted with petroleum as the extractant. The aluminium is precipitated from the remaining solution as the hydroxide and is separated off, and finally the nickel is separated off by liquid-liquid extraction with sodium di(2-ethylhexyl) phosphate diluted with an aromatic solvent as the extractant. Yields of up to 99.5 % of the valuable nonferrous metals present in the waste hydroxide sludges are obtained.

Title: Steel-reinforced polyurethane hard foam - used in mfr. of load-bearing building components
IPC: E04C3/29
Filed: 1977-06-30
Abstract: Plastics, pref. polyurethane, hard foam made in a closed mould and contg. steel reinforcements having superficial profiling, e.g. reinforced-concrete armatures, are used for the mfr. of load-bearing building components. The foaming operation proceeds in dependence of generation and transfer of heat. Owing to controlled rapid loss of heat through the mould walls the resulting foam has relatively small cells giving a dense foam with good resistance to shear. This substantially reduces risk of delamination from the embedded reinforcement. Deformation behaviour of the prods. can be closely controlled to ensure that they will withstand stresses arising in building components subjected to static loads.

Title: Reverse flow valve in extruder head - having ring sliding backwards against a face when screw moves forwards
IPC: B29C45/52
Filed: 1977-08-03
Abstract: A reverse flow valve in an extruder screw head has a freely sliding ring between a wall and a stop surface, with its outer surface sliding inside the barrel while its inner surface leaves a gap for fused polymer flow. A shoulder on the screw head located between the stop face and the wall, has a section to mate with this flow gap inside the ring, leaving space inside the ring; the shoulder opens the flow gap at least when the ring lies up against the front stop face but closes the gap before that position is reached. The system produces virtually uniform weight of mould charge irrespective of the state of the polymer in the extruder barrel.
