Patent FR-2269476-A1 (FR)
Title: Hydraulic conveyor for mushrooms - pumps liquid through cylindrical passages in rotating barrel receiving mushrooms
IPC: B65G53/30
Filed: 1974-05-03
Abstract: Fragile objects, in particular mushrooms, arrive through an entry and drop into a receiver and into cylindrical locations in a rotating barrel. The locations are closed at the bottom by a mesh. The rotation of the barrel brings each location in turn into alignment with an inlet and an outlet tube through which a pump moves water. The mushrooms are entrained and lifted to the outlet channel. The water falls from the outlet of the tube back to the container from where it returns to the pump.

Title: 1-Butene prodn. by ethylene dimerisation - with titanium alcoholate-alkylaluminium catalysts
Inventor: BELOV GENNADY PETROVICH
IPC: C07C2/30
Filed: 1974-06-14
Abstract: 1-Butene is prepd. by dimerisation of ethylene in an org. solvent in the presence of a catalyst system comprising (a) a complex Ti alcoholate of formula (RO)3TiR'.AIR"2OR (where R is 2-4C alkyl; R' = R or H; R" is as defined for R) and a trialkylaluminium or (b) a Ti alcoholate of formula Ti(OR)4, a dialkylaluminium hydride and a modifier comprising dicyclopentadienyltitanium dichloride, O2, m-phenyl-enediamine or N-phenyl-beta-naphthylamine. 1-Butene is used in the prodn. of n-butanol, ethylene/butylene copolymers, isotactic polybutene, butene oligomers and butadiene. Compared with conventional ti alcoholate catalysts, system (a) increases the yield of 1-butene by ca. 25 wt. % and decreases the yield of by-prods. (higher olefins, polyethylene) to 1.7-5.3 wt. % and system (b) increases the yield of 1-butene by 10-20%.

Patent FR-2257861-A1 (FR)
IPC: F23C6/04
Filed: 1974-12-13
Abstract: A flame is produced in a combustion chamber with a burner supplied with fuel and less than the amount of air for complete combustion. The remainder of the air required for complete combustion is injected separately. Stack gas containing substantial carbon dioxide is mixed selectively with the gaseous combustion products. By well known reactions the carbon dioxide reacts with carbon in the combustion products to produce carbon monoxide which is later oxidized to carbon dioxide under conditions which do not promote production of noxious nitrogen oxides. The principles of the invention are applicable to a variety of fuel burners.

Title: Motor vehicle switch with actuating lever - has movable contact carrier with moving contact and fixed contact supported by switch body
IPC: B60Q1/14
Filed: 1974-12-23
Abstract: The switch actuating lever is rotatable about its long axis with respect to the switch body. A relatively movable contact support carries a moving contact cooperating with a stationary contact arranged in the switch body. Between the rotary lever and the contact support is a coupling which enables the transition of the lever rotary motion into a sliding motion of the contact support, which results in the moving contact mating with the stationary contact. Preferably the lever actuates a rotor into a swivelling motion for closing further contacts in the switch body. The contact support and the lever coupling may be brought into swivelling motion with the rotor, while a relative motion between the moving contact and the contact support is carried out in a different direction than the contact mounting.

Title: Closed cycle vapour turbine power system - includes secondary heat pump with auxiliary fluid evaporated as primary fluid condenses
IPC: F01K7/32
Filed: 1975-04-11
Abstract: The primary fluid is evaporated in a boiler and expands in a turbine, doing mechanical work, and passes to a condenser from which it is returned to the boiler by a feed pump. Liquifaction in the condenser takes place by heat exchange with an auxiliary fluid which is evaporated as the primary fluid condenses. This gas is then compressed in order to be liquified at the boiler temp. The liquifaction takes place in a heat exchanger between the feed pump and the boiler in which the primary fluid is heated and vaporised. In this way the heat taken out of the primary fluid in the condenser is returned to it and the overall efficiency is improved.

Title: Preimpregnating tubular textiles with epoxy! resins - to form materials to reinforce plastics for aerospace uses, etc.
Inventor: BROCHIER JEAN
IPC: B29B15/10
Filed: 1976-08-04
Abstract: A process for preimpregnation of tubular textiles (knitted or woven) intended for reinforcing plastics consists in (a) impregnating each element of the textile material with an appropriate resin compsn., (b) drying the compsn. by heating, (c) superposing several such impregnated and dried articles and (d) finally polymerising the deposited resin, esp. by heat and pressure. The treated materials are used, pref. in the shapes of cylinders or cones, in, e.g. radomes, the 'noses' of aircraft and other engines, tail-fins of helicopters, cisterns, pipes, etc., and in the aerospace industry generally. Previous methods of preparing multi-layer impregnated textiles were unsuitable because of costly techniques, e.g. use of devices to rotate the cones during polymerisation, or because of the filtering effect of layers of textiles, giving uneven impregnation. The present method is simple, economic and rapid; and gives semi-finished prods. that are homogeneous and easy to transport, stock and put into use.

Title: Pressure-sensitive security system for bank strong room - has tubular gas filled panels lining inner faces so that pressure drop actuates alarm
IPC: G08B13/20
Filed: 1977-04-12
Abstract: The pressure-sensitive security system is for use in bank strong-rooms etc. and includes panels filled with gas under pressure to line the interior faces of the room.
