Title: Plastic sliding fasteners - moulded from identical interlocking elements
IPC: A44B19/14
Filed: 1972-01-27
Abstract: Injection moulded plastic elements with a hollow longitudinal tubular passage united to a projecting fixing strip on one side, are cut transversely to form identical trapezoidal teeth and recesses capable of interlocking, and the fixing strip is compressed to form thin sections spaced at the same intervals as the teeth, A cursor unites the two strips which are attached to the fabric. The fastener can be injection moulded and fabricated in one piece, and does not require critical fitting. The thin sections provide longitudinal flexibility and are situated behind the teeth, these projecting from a continuous thickened rim which acts as a slide for the cursor.

Title: Flush sliding-door railway goods wagon side - has stop faces on end and centre pillars for stops on sliding sections
IPC: B61D19/00
Filed: 1974-05-28
Abstract: The van incorporates end wall pillars, centre pillars, upper chord and underframe longitudinal carriers, and sliding side sections which lie in one continuous plane when closed. The stop faces at the top and bottom of the pillars are drawn out in front of those on the sliding sections, which have corresponding stops or stop faces at their vertical longitudinal ends. When they are closed the sliding sections' stop faces ae set with play allowed in front of those on the pillars, at least corresponding to the permitted frame corner displacement in connection with frame distortion about the longitudinal axis. Torsion is not checked by rigid clamping of the sliding sections, and these help to transfer buffer jolts from the sides to the underframe carriers.

Title: Bulk mfr. of red wine using cold sulphiting - to accelerate extraction of colouring matter from grape skins
IPC: C12G1/02
Filed: 1975-05-22
Abstract: The colouring substances, anthocyanins, are extracted rapidly from the grape skins, without heating, by a massive sulphiting, i.. at a rate of 30-40 gms. of SO2 per 100 kg. of fresh marc sepd. from its must as soon as the grapes are received. Maceration of the marc then takes place for a period long enough to ensure that the kins break down sufficiently, the maceration being effected in a strongly sulphited medium within a controlled atmos. of CO2. The sepd. must is pref. fermented simultaneously in a controlled atmos. of CO2 and is completely free of SO2. On leaving the macerator, the marc is remixed with its original quantity of must, now fermented to a density of 1030 to 1025, and the prod. refermented so that the colour diffused throughout the must and the wine finishes at a density of about 995. The extn. of colours from the grape skins is greatly accelerated. The processing time is down from 4-6 days to about 48 hours, the size and cost of the installation is roughly half that of previous systems. Final SO2 content of wine is legally acceptable.

Title: Semi-finished product store for drawing bench - with altered drum positioning to avoid bending of product
Inventor: SHEVAKIN J F
IPC: B21C49/00
Filed: 1975-10-02
Abstract: The product store avoids the torsion of the semi-finished products, and contains two drums, of different diameter, with parallel axes, on a base. The facing base surfaces of these drums are at right angles to the drum axis. The store contains a guide for the product, during the winding off the large drum onto the small drum. For this winding procedure, the drums are eccentrically positioned, with a relative staggering of their axes, which is that same as half the difference between the diameters of the facing base surfaces. The drum with the smaller diameter may be displaced in both directions about the axis of the larger drum.

Title: Linearly extensible trench sheeting panel - has two interfitting frames of sheeting rails and poling boards which slide w.r.t. one another
Inventor: ORTEGA ANDRE
IPC: E02D17/08
Filed: 1975-11-24
Abstract: The linearly extendable trench sheeting system has frames comprising poling boards (12) and sheeting rails (13) and successive frames fit one inside the other permitting relative linear displacement. Freshly excavated trenches may thus be lined by sliding and drawing one of the panels forward. The sheet rails of the interlocked panels lie in the same vertical plane. In the simplest form the sheet rails (13) in a particular panel are spaced at a distance equal to twice the sheet rail depth. The rails (23) of the interlocking panel are at a similar vertical spacing and locate between the rails (13) of the first panel. Where subsoil conditions require continuous sheeting the rails (13) may be of 'T' section ie. leg horizontal, and the bars of successive rails (13, 23) overlap in the vertical senses. Struts (14, 24) between poling boards (12, 22) complete the system.
Patent FR-2294532-A1 (FR)
IPC: H01H37/54
Filed: 1975-12-12
Abstract: In order to enlarge the usable switching path and in order to define the switching temperature more precisely, the bimetallic component (which is in the form of a plate) has an opening (14) into which a switching tongue (12) projects which is free at one end. The latter is arranged essentially centrally in a dome-like region whose curvature reverses, with a snap-action effect, when the temperature changes. The inner circumferential line and curved sections of the outer circumferential line of the opening (14) are connected in a flowing manner to rounded ends of the opening (14), to be precise close to the root (18) of the tongue. The width (g) (which is measured essentially radially from the centre of the dome-like region) of said dome-like region is larger in the region of the root (18) of the tongue than in the other part of the region. The length of the tongue (12) is greater than the tongue width, measured at the point halfway along the length of the tongue. The device is suitable in particular as an electrical switching element or mechanical operating device for electrical devices.

Title: Frame for independent suspension - having flat metal stamping with bearing holes and bent flanges for welding
IPC: B60G15/06
Filed: 1976-02-09
Abstract: A flat metal sheet is stamped with the selected shape for the rear suspension support, complete with holes for the attachments. The top and bottom edges (21, 22) are bent over and fitted with bearing sleeves for the suspension elements. These sleeves are simply welded to the frame. The lateral stability of the frame is obtained by bending side flanges (1) over at either end and welding the edges to the sides of the top and bottom flanges. The frame is strong, light and compact and requires no complicated castings, forging and machining, only simple stamping and seam welding.

Title: Elastic cores for building hollow reinforced resin profiles - for ease of core detachment and removal in tension
IPC: B63B5/24
Filed: 1976-03-05
Abstract: Hollow profiles are made from fibre-reinforced resins by laying up impregnated fabric or mat to enclose temporary inserts made of rubber to thermoplastic material sufficiently elastic to be subsequently withdrawn under tension. Used for mfr. of tubular or multichannel profiles of glass and/or carbon fibres impregnated with polyester or epoxy resin esp. for articles requiring high strength/stiffness ratios. Unlike rigid inserts or mandrels of e.g. wood or metal, elastic profiles in tension can reduce their dimensions normal to the tensile axis sufficiently for disengagement and removal.

Title: Solar water pump with transparent tank - with layer of volatile material floating on water in tank
IPC: F04F1/04
Filed: 1976-07-06
Abstract: Solar water pump comprises a transparent tank allowing solar radiation to vaporise a thin film of a light insol. volatile prod. floating on the water in the tank. The film is rendered black so that variations in pressure of the vapour between day and night expel the water under pressure during the day, while at high condensn. of the volatile prod. causes a redn. in pressure which draws the water by suction from a well to which the system is connected. The volatile prod. is pref. rendered black by colouring, by flotation of a black body of specific gravity less than that of water, or by inserting between water and film a flexible black membrane which avoids direct contact with either, and which has a porous surface for contg. the volatile prod.
