Title: Packages banded with plastics tape - using independent holding and welding units which avoid any pull back of tensioned band
IPC: B65B13/32
Filed: 1974-01-30
Abstract: An appts. for clamping and closing plastics bands or strips used in packaging comprises a clamping roller which is used for pressing the band against >=1 pref. 2 rolls. The clamping roll is actuated by 2 sets of couplings. The first coupling transmits the oscillating lever motion of the actuating handle to the roll in one direction only, while te other set prevents a return motion in the return intervals of the lever. Thus a ratcheting angular motion of the lever is converted into a unidirectional rotation of the clamping roll. In a separate gp. of equipment, another actuating lever synchronously operates three devices which cut the band, and introduce and remove the sealing electrode used for joining the band ends.

Title: Aircraft approach location system - using phase modulation depending upon aircraft distance from aerial
IPC: G01S3/52
Filed: 1974-02-20
Abstract: A transmission from an aircraft is detected by an airport rotating aerial system.

The process includes correlation by modulation following a law analogous to those of the detected signals. This correlation is then followed by an integration. The aerial system consists of two aerials mounted at the ends of an arm which rotates around a central axis. The signals detected by either of the electrodes are mixed with the outputs of two local oscillation, and after common amplification, from the object of a quadratic detection.

Title: Sealing structural cracks with foaming thermoset resins - esp. for bridging and blocking divergent crevices
Inventor: ALBERTS C Y H
IPC: E21D9/00
Filed: 1974-06-12
Abstract: Blocking or filling of cracks by introducing a thermosetting resin compsn. incorporating a blowing agent and subsequently reducing the atmospheric pressure in the crack and activating the foaming agent to expand and cure the resin within the crack. Claimed for filling or blocking cracks or cavities in rocks or in constructions made of concrete, brick, timber, etc., esp. using mineral and/or organic blowing agents. The type of resin is not critical, and it may be applied as a liq., paste, gel etc. as appropriate. Foaming mixts. tend to fully flood irregular or divergent cracks or crevices and eliminate trapped air pockets. The viscosity increase induced during foaming at reduced pressure inhibits draining of the resin system from the crack prior to curing. Less resin is needed when in a foamed state to bridge the crack.

Title: Organic Triplex (RTM) glass prodn. - by coating functional organic semi-translucent layer with inorganic colourless semi-translucent layer before laminating
IPC: B32B27/30
Filed: 1975-11-25
Abstract: Light-filtering, heat-, radiation-reflecting or electrically heated organic triplex glass (RTM) is produced by depositing an inorganic semi-translucent coating on organic glass by thermal vacuum evaporation. Glass is then bonded, in triplex process, with similar coating-free organic glass. Triplex bonding is preceded by applying an inorganic, colourless, semi-translucent coating (II), by thermal vacuum evaporation, onto the inorganic semi-translucent coating (I). Triplex glass is used for glazing cabins of ships and aeroplanes, car windows, spectacles, helmets, goggles, etc. (II) acts as a protective coating and prevents damage to (I) in triplex process, caused by activity of polyvinyl butyral foil.
Patent FR-2333993-A1 (FR)
Title: Fitting por T-grooved sections - has quarter turn locks with two bars joined by rotation nut fitting joining sections end to end
IPC: F16B7/20
Filed: 1975-12-03
Abstract: This fixing is designed for the assembly of structural elements which have longitudinal grooves of T section. A short bar (2, 3), just wide enough to be inserted in the slot of the T groove is rotated after insertion, so as to bridge the gap and prevent extraction. The bar is joined to a similar bar via the intermediate rotation nut (4) to which the spanner is applied. When two grooved sections are joined by the fitting, the rotation nut lies between them. Each bar has a conical spike (9) in the centre of the face opposite the rotation nut and has diagonally opposite lower edges (18) chamfered. Its depth is such that when rotated, the chamfers bear on the inner slot edges and force the spike into the opposite face of the T groove, so preventing longitudinal movement.

The end posts (1, 2) are joined by appropriate traverses, and contain the service pipes to the sanitary fittings. The fittings (11, 15) may rotate about horizontal axes which are mounted in openings in the post (1, 2) section walls. The azle also serves as the waste pipe with a diametric flexible pipe leading to the base.
Patent FR-2338129-A1 (FR)
Title: Injection moulding head with a subsidiary piston for cavity packing - for precise pack and dwell pressures following screw injection filling
IPC: B29C45/57
Filed: 1976-01-19
Abstract: An injection moulding machine has a melt accumulator chamber between the screw plasticization chamber and the nozzle, part of which can be isolated by non-return valves in the nozzle and downstream from the screw tip. The chamber incorporates a hollow piston which can be shifted by external rams independently of the screw. Screw motion is used to fill the moulding cavity, but cavity packing and dwell pressure is applied by the ancillary hollow piston, allowing the screw to retract and replasticize independently of the cavity dwell press. requirements. The mould packing and dwell pressure can be more precisely controlled and reproduced than with systems relying solely on screw motion or using a large subsidiary piston to transfer the full moulding shot. Esp. suitable for applying non-constant or non-linear mould packing pressure.
Patent FR-2339982-A1 (FR)
Title: Large power distribution network - has remote monitoring system to remotely switch given loads to network and measure perturbation
Inventor: PAILLET JACQUES
IPC: G01R27/16
Filed: 1976-01-29
Abstract: The remote monitoring system determines the condition of remote equipment in a large power distribution network. A given signal is transmitted by one or more synchronised central stations to the numerous local outstations connected to the network. The signal causes power load circuits to close in the outstations and given loads to be connected in. The perturbations on the network caused by these loads are then measured. The station detecting the perturbations is linked to the central transmitting station, which may house a computer to evaluate the results.

Title: Sepn. of polyphenols from vegetable extracts - by conversion to their betainates and fractional precipitation
IPC: C07C37/00
Filed: 1976-04-12
Abstract: Polyphenols such as monomers and oligomers of catechins, leucocyanadins, or their derivatives are sepd. from polyphenol-rich vegetable extracts by treatment with betaine base in an alcoholic medium and fractional pptn. of the polyphenol betainates. Cpds. are anti-oxidants for foods, they improve permeability of capillary vessels, are anti-inflammatories, and leucoanthocyanidols and their oligomers and polymers are useful in preventing tumours. Process is simpler and cheaper to carry out than known methods of separation. Typically a stoichiometric amount of betaine is added, and the polyphenols are precipitated by addition of a 3-5C aliphatic alcohol. In an example maritime pine bark extract (30g) was treated with 15g betaine base and polyphenols pptd. by gradual addition of isopropanol, n-butanol, and ethyl acetate.

Title: Integrated memory matrix programmable by external wiring - has reading storage elements on common substrate and connected by electric conductors in columnar array
IPC: G11C17/16
Filed: 1976-05-21
Abstract: The common substrate has diffused into it several double emitter transistors. Their first emitter ranges are connected row-wise to first electrical conductors and their second emitter ranges are connected column-wise to second electrical conductors. Programming is performed by external feeding of a current via the appropriate row and column conductor of a transistor to an intersection for programming and by the short-circuit thus generated in at least one base-emitter stage. The supply current can be such that an emitter is short-circuited with base and collector.
