Title: Prefabricated truss roof structure - has longitudinal timber beams bearing on gable end to reduce truss loading on main walls
IPC: E04B7/02
Filed: 1975-03-10
Abstract: The roof structure consists of completely or partially prefabricated trusses (5,6,7) and eliminates the need for concrete bearing pads under the roof. The frame is supported on the tops of the buildings walls (8,9) and beams (18,19) are laid perpendicular to the planes of the trusses. The ends of these beams rest on the transverse gable-ends (11) or walls and are linked to the uprights (16,17) of the trusses so as to support them in cooperation with the tops of the walls. To erect the frame, the trusses are placed vertically in the usual way on the tops of the walls. The beams are inserted into position and attached to the transverse gable end walls. Finally, the trusses are attached to the beams. Each individual trusses should not exceed a height of 3.9m, in order that it can be transported in one piece.

Title: Alternator with superconducting rotor - has copper rod screen and end laminations minimising damage due to overheating
Inventor: GILLET ROGER
IPC: H02K55/04
Filed: 1976-02-27

Title: Bacillus thuringiensis insecticide prodn. - without premature cell lysis by maintaining pH of 6.3 to 7 and/or applying anaerobic conditions during cultivation
IPC: A01N63/50
Filed: 1976-05-13
Abstract: Biosynthesis of a microbial insecticide contg. spores and crystalline endotoxin, comprises cultivating the microorganism Bacillus thuringiensis or a related bacillus with spore-formation, in a nutrient medium in so that the early cell-lysis, caused before completion of spore-formation by aeration during the course of the submerged cultivation, is inhibited. The insecticide is pref. sepd. from the toxic water-soluble exotoxin also produced by the microorganism by dialysis. Premature cell-lysis leads to low yields of the insecticide and an increase in its toxicity. This premature cell-lysis is avoided by carrying out the biosynthesis under an-aerobic conditions for 4-6 hrs. at pH 6.3-7.

Title: Bronze electric contacts with local gold coating - on only one flat surface of a hexagonal wire
Inventor: MATHYS WALTER
IPC: H01H11/04
Filed: 1976-11-10
Abstract: Contacts are made coated with precious metal on a limited local zone. Hexagonal bar of an electrically conducting material is coated on one of its six faces with precious metal. The bar is then rolled, drawn, or rolled and drawn into profiled wire; the wire is soldered along a fixed length to a support and cut, followed by rivetting or stamping to obtain a hemispherical contact. The faces of the hexagon which will be welded to the support are pref. made concave so that at the start of welding the wire only rests by two edges on the support. An electrode with a V-shaped profile is pref. used to weld the hexagonal wire onto the support when the precious metal coating is next to the surfaces in contact with the electrode, i.e. so the electrode does not touch the precious metal. Used for e.g. gold coated contacts, where only one of the six flats is coated to use the min. amt. of Au, and also to permit oblique contact, e.g. with the periphery of a tubular contact.

Title: Demountable bollard for controlling vehicle access - has vertical lever pivoted by lock bolt to engage ground anchor
IPC: E01F13/06
Filed: 1976-11-19
Abstract: The demountable bollard (1) may be used to prevent vehicle access and has a key-operated lock mechanism. The post is hollow and contains a vertical lever (10) which can pivot about a horizontal axis (9) which locates at approx. the top third point of the lever (10), and the top of the lever (13) is constrained (19) to bear on the bolt (14) of a key-operated lock (15). The foot of the lever has a notch (12) which can engage a ground-anchored stirrup (8). The operation of the lock displaces the bolt which in turn displaces the top of the lever. The lever then pivots causing the notched foot to engage the stirrup mounted on a base plate.

Title: Laminated PTFE strips for flexible heating tapes - incorporating parallel conductors for uniform power output
IPC: H05B3/58
Filed: 1976-12-20
Abstract: Composite heating strips comprising a layer of sintered PTFE cong. sufficient (1-10%) carbon black to have a volume resistivity of 0.001-0.02 ohm.m, this conductive layer being enclosed in an insulating sheath made of two layers of non conductive PTFE strip joined along their borders. The conductive layer is 40-1000 mym thick, 4-100 mm wide and incorporates twin metallic conductors parallel to and near the borders of the conductive layer. Used for flexible heating tapes for wrap-round application, typically of 5-80W output at 220V. Unlike cables with terminals each end, the power dissipated per unit area is nominally independent of the cable length, allowing tapes up to 50 m long to be made as a single strip without successive connections which have to be electrically coupled in parallel.
Patent FR-2386679-A1 (FR)
IPC: E05G1/026
Filed: 1977-04-04
Abstract: A strongbox compartment (1) is closed by a door (2). In order to actuate the locking means (3) of this door (2), it is necessary to actuate two locks (4, 5) by means of two different keys. In order to make it even harder to break open the compartment (1), a framing (6) for a second door (7) with a leaf (7a) is installed inside the compartment (1). The framing (6) is fixed to all the internal walls of the compartment (1). The leaf (7a) comprises locking means. With a door framing of this type, it is easy to reinforce strongbox compartments which are already installed and which comprise only one door.

Title: Yarn texturing tube assembly, processing without moisture - has self contained steam generator enclosing vibrated bulking tube
IPC: D02G1/18
Filed: 1977-04-12
Abstract: Yarn is bulked in a continuous process by its being fed into a tube in which is banked up arbitrarily by subjecting the bulking tube to light vibration. The yarn in the stack is quite free from tension and steam generated in individual boilers for each tube is blown through. The process is effected without humidity since the steam or hot air supplied is evacuated immediately before there is any condensn., as the yarn gradually leaves the tube. The yarn is bulked by treatment in an absolutely untensioned condition, without becoming humid, since it is released into the atmos. before the steam begins to condense.

IPC: D06M101/16
Filed: 1977-08-05
Abstract: Prevention of incrustation on hot surface is achieved using metal salts on filaments, the filaments having >=0.001wt.% metal salt of the formula (I): (where R1 is 1-6C alkylene. R2 is 1-6C alkyl. R3 is 1-5C alkyl. R4 is H or as R3. n = 1-4. M is a metal atom, e.g. Na, K, Ba, Cd, Zn, Al, Co, Sn, Ni, Cu).

Patent FR-2389930-A1 (FR)
IPC: G04C3/14
Filed: 1977-10-04
Abstract: The present invention has as an object the provision of an electromechanical analogic display device for electronic chronometers, comprising at least an electromagnetic motor controlled by an electrical impulse of short duration. The attractive influence of the latter distorts a spring, very rapidly storing the produced energy to release it in the form of kinetic energy and driving a toothed wheel coupled to the analogic display while on the other hand this electromagnetic motor activates a locking system permitting the passage of a single tooth per cycle, and thus assures for said device immunity from mechanical shocks and most particularly from tangential accelerations.
