Title: Porous reinforced thermoset resin tubing mfr - using inflation of an impermeable sleeve to support uncured zones
IPC: B29C70/16
Filed: 1974-06-13
Abstract: Tubing prodn. from reinforced thermosetting resin is by guiding an impermeable flexible film over a hollow mandrel to form a tubular sleeve which is successively overlaid with helically wound and longitudinally laid filaments which have been pre-impregnated with thermosetting binder resin compsns. Lay-up occurs over a solid cantilevered mandrel which is relatively short and which supplies an internal fluid pressure which sustains the tubular shape of the lining film by inflation until the resin is sufficiently cured for the would structure to be self-supporting. Partic. for mfr. of land drainage pipes or similar required with porosity for passing liq. through the wall. Supports tubing for period necessary for curing during mfr. without requiring excessively long internal mandrels and consequent haul-off resistance.

Title: Hydraulic damper with piston separating chambers - has venturi flow restrictor in piston connected with compensating reservoir
IPC: F16F9/34
Filed: 1974-10-03
Abstract: This hydraulic shock absorber imposes little restriction on slow movements such as might occur between pipes and nuclear reactors, due to temperature changes, but effectively damps higher rate loads. This protects the adjacent elements in the case of earthquake, explosion or other failure. The damper is formed from a cylinder with end plates and a piston with hydraulic fluid on either side. An orifice in the piston is fitted with a venturi fluid restrictor formed from two nozzles (19, 20) between which a channel (24) connects to another reservoir. The nozzle induces additional fluid from this reservoir during high loading when there is a reduction in the volume of the fluid on the pressure side of the piston, due to compressibility of the fluid.

Title: Grafting of polymers on to fillers - comprising partial reaction with a polyfunctional cpd eg an aminoalkylamine deriv and aldehyde
IPC: C08K9/04
Filed: 1975-03-27
Abstract: Grafting of a polymer on to a filler is achieved by reacting a crosslinking agent with the mineral particles of the filler while leving one or more functional gps. unreacted and subsequently adding a cpd. which is capable of reaction with these residual gps. and produces after heat treatment at 100-150 degrees C an organic polymer strongly bonded to the filler. By use of such grafted fillers for various industrial purposes, such as the prepn. of rubber, plastics or coating compsns., the props. of the filled prod. are improved. Grafting to fillers has previously involved the use of organo-metallic cpds., isocyanates, siloxanes or silanes and solvents in conjunction with a hydrocarbon monomer. These processes are costly and difficult to carry out, whereas that of the invention can easily be performed in situ.
Patent FR-2273106-A1 (FR)
Title: Bulking and producing pile on textile fabric - using oscillating needles having series of juxtaposed barbs
IPC: D06C11/00
Filed: 1975-05-28
Abstract: A textile fabric is needled using needles having a series of juxtaposed barbs to bulk the fabric and produce a pile on the needled surface. Pref. about 30% of the thickness of the fabric is affected. The method is used for producing matls. used in upholstering.

Patent FR-2324895-A1 (FR)
Title: Hydroelectric power plant starting system - using generator as motor to drive plant up to synchronous speed before water admission (BR 5.4.77)
Inventor: MEGNINT LUCIEN
IPC: F03B15/00
Filed: 1975-09-19
Abstract: Electric current is supplied to the generator so that it operates as an electric motor and drives the plant until synchronous speed is reached. At the same time a control valve is opened so that water is admitted to the turbine. This reduces the time required to achieve full speed, and limits the heating of the generator. By reducing the water flow required the back pressure downstream of the control valve and cavitation at the valve outlet are reduced.

Title: Textile fibre and down separator - has tapered, slack filter sleeve between cyclones, vibrated to prevent clogging
Inventor: FAVRE JEAN-PAUL
IPC: B07B7/06
Filed: 1976-05-14
Abstract: A filtration system for sepg. fibre and down from a flow of air in e.g. textile plant, has a cyclone discharging into a chamber with a filter sleeve attached to a right angle bend connected to a smaller cyclone outside the chamber. A larger discharge tube with a fine filter is mounted at the other end of the chamberin line with the filter sleeve. This sleeve is mounted inside a perforated flexible sleeve. A body mounted in front of the mouth of the filter sleeve, causes turbulence. The sleeve is mounted slackly between its attachment points, and layers inwards. This results in a vibration sufficient to prevent clogging. In an alternative design, instead of the body, flexible ribbons are attached to the sleeve to cause turbulence. The mesh of the filter is 100-1000 mu, pref. 150-650 mu. The speed of flow is 3-30 m/s pref. 10-15 m/s.
