Patent FR-2273120-A1 (FR)
Title: Precast prestressed concrete tunnel lining blocks - keyed together to form self-supporting arch structure to tunnel dimensions
IPC: E21D11/08
Filed: 1974-05-31
Abstract: The precast block used in tunnel construction has a triangular-section groove (2) running the length of one face. On the opposite face is a rib of similar-section. The rib on one block fits exactly into the groove on the adjacent block and when sufficient blocks are fitted together in this way, a self-supporting arch structure is formed which needs no reinforcing or additional fastening. The blocks should preferably be made of prestressed concrete and the dimensions will vary according to the size of the tunnel. The section of the rib and groove can be any desired shape. Although the use of these blocks avoids the need for shuttering while the tunnel is under construction, a roof-support should be used.

Title: Masses for suppositories - prepd. by esterifying glycol with lauric myristic, palmitic and stearic acids
Inventor: WAGINAIRE LUCIEN
IPC: A61K9/02
Filed: 1974-06-20
Abstract: A process for prepg. masses for use as suppository bases comprises esterifying in the absence of a catalyst a mixt. of 5 molar parts of glycerol and 1 molar pt. of a polyoxyethylne glycol (pref. mol. wt. 200-2000) with 13.5 molar pts. of a mixt. of lauric, myristic, palmitic, and stearic acids. The prod. is homogenous and hydrophilic so that the difficulties encountered with conventional suppository bases are overcome (e.g. slow release of active ingredients and low mechanical strength). The prods. are non-toxic and non-irritant.

Title: Catalyst complex for olefin polymn. - prepd. from magnesium, org. hydroxy cpd., transition metal org. cpd. and aluminium halide
IPC: B01J31/26
Filed: 1974-09-02
Abstract: alpha-Olefins are polymerised in the presence of a catalyst system comprising an organo-metallic cpd. (B) the metal being a Gp. I to Gp. III metal and a solid catalytic complex (A) (claimed) formed by reacting (1) metallic Mg, (2) an org. OH gp.-contg. cpd. (3) an oxygen-contg. or contg. org. cpd. of a metal Tr of Gp. IVa, Va or VIa, and (4) an Al halide. The catalyst system has the same advantages as those of BE 791676; e.g. high activity, broad mol. wt. distribution are good impact resistance of the polymer, with the additional advantage that it may be prepd. from more readily available cpds. and obviating the use of unsatable or dangerous materials.

Title: District heating system esp. for nuclear power stations - has compensating circuit to balance summer and winter demand
IPC: G21D1/02
Filed: 1975-04-18

Pref. by-pass connections between the flow and return pipes are made at long intervals. The system enables the varying thermal demand in district heating systems in winter and summer conditions to be compensated by increasing or decreasing the heat losses as the temp. in the return lines rises or falls.

One face (PB) of an angle plate (EQ) is pushed into the groove in the existing frame (CH), and the horizontal face (GB), provides a support for the joint. The horizontal face has an opening (OU) for the tongue (LA) of a sprung steel plate (RE) which has a horizontal face and a face bent back at an acute angle. The sprung plate compresses the joint against the existing pane to give a weathertigt and sound proof seal.
Patent FR-2323117-A1 (FR)
Title: Furnace roof with internal protective coating - comprises layered ceramic fibres clamped in box support from hangers
IPC: F27D1/02
Filed: 1975-09-04
Abstract: Furnace roof is formed by applying rigid insulating panels of layered ceramic fibre fleece and an outer layer of ceramic fibre mat of high refractoriness. The roof is formed of rectangular modules of about 1 m2 area, comprising boxes made from sheet steel, each having flanged edges on all four sides and >=2 stiffeners fixed at their ends to certain of the flanges. The roof is supported from these modules by both passing through holes arranged in the mass of fibres so as to compress folded-over parts of the mat-trapped against the flanges of adjacent modules and which are applied in the cold against the edges of the rigid insulating panels and the layered fleece. Application of the ceramic fibre mat can be effected taking account of the shrinkage which the mats undergo as the temp. rises, so as to void melting the material in a direction which would produce gas passages risking damage to the weakest insulating panels or the metal of the roof.
Patent FR-2329131-A1 (FR)
Title: Helical wire element for space heater - is wound around semicircular supports by rotating whole support frame
IPC: H05B3/32
Filed: 1975-10-22
Abstract: The helical wire heating element, for space heaters, consists of two semicircular insulating supports (1,2) mounted between two parallel metal supports (3,4). One or more insulating spacers (6) with T-shaped slots set into their top and bottom edges are located between the metal supports. The whole assembly is rotated about the spacer's axis and the helical heating wire (10) with a central coaxial asbestos cord is wound lengthwise around the insulating supports (the latter have ridges as guides). The wires passing over the spacer are now displaced to the right and those passing below it are displaced to the left. The result is a cross-over. The advantage lies in speeding manufacture and increasing heat output.

Title: Electromagnetic relay with bistable memory - has moving part with magnet and contact which can remain in one of two positions on de:energisation
IPC: H01H51/22
Filed: 1975-12-12
Abstract: An electromagnet relay may be used as ordinary relay or as a permanent bistable memory device. The relay has a cylindrical part (3) carrying a magnet (6) and an electrical contact (2). The cylindrical part (3) may be actuated by a current-energised coil (5). When current flows through the coil (5), the magnet (6) moves towards or away from the coil (5) according to the direction of the current. During energisation of the coil (5) the moving contact (12) bridges two fixed contacts (1) or moves away from the contacts (1). On de-energisation, the moving contact (2) remains in one of the two positions. Stops (7, 8) are used to prevent the magnet (6) to move in-line with the axis of the coil. The cylindrical part (3) may be replaced by a spherical part.

Title: Charging fluids, partic. gases, into an oscillating reactor - by ducts controlled automatically to direct fluid most effectively
IPC: F27D17/00
Filed: 1976-05-05
Abstract: Appts. for charging a fluid, partic. a gas, into a reaction chamber, which oscillates about longitudinal axes, incorporates ducts circulating the gas near the wall of the chamber and discharging into nozzles near the roof of the chamber, connecting the ducts with the interior of the chamber. The nozzles are positioned along chords and so that, during the oscillation of the chamber, they are never covered by the products in the chamber. They are distributed symmetrically on one side and the other of a longitudinal plane. They can be opened or closed by automatically operated butterfly valves, according to their position so as to direct the gases constantly onto the base of the materials being treated. The invention increases the efficiency of the treatment to which the prods. are subjected, whether they be solid, liqs. or pastes, compared to existing reaction chambers. Combustion is more efficient. The construction is simpler.

Title: Monitor for circuit activity in automatic telephone exchange - utilises principal processor controlling auxiliary units which perform monitoring procedures on traffic density
IPC: H04M3/36
Filed: 1977-03-09
Abstract: Several auxiliary microprogrammed microprocessors are employed to monitor activity of electrical circuits within an automatic telephone exchange. A principal processor performs appropriate calculations to determine required information such as traffic density and defective circuits. A number of auxiliary monitoring stations (100) collect activity information of parts of an exchange. Each monitor contains an auxiliary processor (103) controlled from information on a bus (106) from a principal processor. The auxiliary processors control exploration by addressing the monitor circuits (101) connected (102) to various monitored points. When these processors are addressed the monitored information is transmitted via connections (109) onto a bus (108) to the principal processor.
