Title: Gasometer tank for purified methane prodn. - from organic matter such as manure
IPC: F17B1/02
Filed: 1974-03-29
Abstract: Gasometer tank, for the prodn. of methane from organic materials, comprises >=1 fermentation tank with a side wall surmounted by a bell which can move in the vertical direction. The skirt of the belt dips into the upper circular gutter, between walls. The tank is covered by an insulated lid, made from a lattice and expanded polystyrene. This lid rests on a skirt in hydraulic joint. >=1 tube passes through the lid for the passage of gas. The gas is also evacuated, by its own pres., by a pipe to a purifier which eliminates CO2 and H2S; it then rises into the bell. During fermentation of the organic material, such as manure, it expands and has a tendency to float. To keep it completely immersed it may be covered with expanded metal kept in position by tubes with their ends under the shoulder of the water seal. Radiation losses are reduced to an insignificant quantity. By the purificn. of the gas between the point of prodn. and storage, the vol. to be stored is reduced and the purified gas gives a better performance in the appts. used subsequently.

Title: Transmission belting with low deformation factor - has radial and transverse fibres resisting belt deformation
IPC: F16G5/06
Filed: 1974-04-22
Abstract: The conventional transmission belt has longitudinal fibres running close to, and parallel to, the wider upper surface, and transverse fibres beneath these, all embedded in a rubber matrix. This belting has the conventional longitudinal fibres (1), but the transverse fibres are interspaced with two layers of radial fibres (4). This gives lower radial distortion for radial load, and hence less overheating. The radial fibres may be inclined w.r.t. the radial direction of the belt at an angle typically between 0 and 30 deg.

Title: Semirigid coupling for power transmission - has shaped metal teeth to transmit load when shafts are misaligned and vibration damping elastomeric insert
IPC: F16D3/18
Filed: 1975-10-06
Abstract: The semi-rigid coupling consists of two identical members (1,2). The outer ends are provided with serrated bores to fit the shafts (4,5). The mating ends of the half couplings are provided with circumferential teeth with convex faces which permit a limited amount of angular misalignment between the shafts. The bore (9) of the mating ends of the half couplings is filled with an elastomer which is compressed between the discs (11). The elastomer transmits the loads under normal running and absorbs vibrations. If the shafts become misaligned the load is transmitted through the teeth, preventing any overloading of the elastomer.

Title: Variable compression rate helical spring - has wire of gradually changing cross section varying from square at ends to round at centre
IPC: F16F1/08
Filed: 1975-10-07
Abstract: The helical springs described are useful in vehicle suspension systems where a low spring stiffness is required with light loads progressively increasing as the load increases. To achieve this, the spring wire is made with a section varying gradually (2,3) from square (4,5) at the ends to round (1) in the middle. With a spring of this form, the outer coils are weaker and as the spring is compressed, progressively lie against each other. The construction also ensures a light weight spring which can have a short length when compressed. Variants with smaller diameter coils at the ends than the middle are given and the compression law can be tailored as required. Machines for rolling the wire cross-section from circular to square and for winding the springs are also described.

Title: Plastics shoe processing adhesion press - has thin resilient press mould withstanding high breaking stresses to bend foil at edges
IPC: A43D25/07
Filed: 1975-11-12
Abstract: A press mould (5) of a thin resilient material, e.g. rubber, defines the side wall (7) of the press and has its ends (6) bent round the ends of the side wall (7) which is cylindrical and pressed against the base (3) of the press by a collar (8).

Seals (11) are provided to hermetically seal the press mould (5), the base (3) and the stopper (12). Differential pressure is produced between the inner area of the chamber and the outer area by a suction system connected to the interior of the chamber and at least one inlet which connects the outer part of the chamber to the atmosphere. This differential pressure causes the press mould (5) to abut the workpiece (14) along its side and remaining faces.

Title: Vehicle safety steering wheel - has spokes with zones of weakness for collapse in event of collision
Inventor: AMALBERTI JEAN-CLAUDE
IPC: B62D1/08
Filed: 1976-03-30
Abstract: A vehicle steering wheel has a rim (2) connected to a hub (11) by two spokes, each spoke have an approximately horizontal port (8, 9) followed by a nearly vertical part (5, 6). At the bend (A, C) between these two parts and just above their junction (B, D) with the boss, the spokes are deformed by partial flattening. These portions are sufficiently strong to transmit all steering forces, but provide zones of progressive collapsing in the event of a collision, to protect the driver. These deformations can be made by using suitably shaped forming blocks during fabrication of the spokes, and can be covered with conventional sleeving after assembly.

Title: Extensible waistband for trousers or skirt with opening or fly - joined by stretch seam to elastic band inside waistband
IPC: A41F9/02
Filed: 1976-06-25
Abstract: Extensible waistband for trousers or skirt with opening, fly, etc. comprises a fabric strip pref. of the same type as that of the garment folded back on itself to form a sheath in which is housed an elastic band (4). According to the novelty the waistband is fixed to the upper edge of the garment (3) by an open seam (7) passing only through the outer wall of the sheath. The lip (8) which is thus formed along this wall and turned back towards its inner surface is joined by a stretch steam (13) to the lower edge of the elastic band. The free edge of the other wall or inner wall (15) of the sheath is joined by a stretch seam (16) to the other lip (9) formed by the open seam along upper edge of the garment.

Title: Missile with self destruct after missing target - has weighted arm to hold firing pin due to centrifugal force of rotation to release when slowing
Inventor: CASTERA ANDRE
IPC: F42C9/18
Filed: 1976-09-13
Abstract: The unit ensures that a missile missing its target will self destruct on slowing down. It comprises a pivoted (12) C-shaped jaw (14) having a weight (16, 18) at the end of each arm. One arm rests under a firing pin (O) preventing its operation. The other arm has a third arm (22) pivoting on it This third arm carries a weight (24) and is spring loaded (26). The centrifugal force due to the initial speed of rotation maintains this third arm open. As the missile slows down, the spring overcomes the centrifugal force and the arm moves inwards against the jaw to release the firing pin.

Title: Aerodynamic force effects modification on gyroscope wheel - is effected by inclining inner face of wheel support structure relative to wheel
Inventor: GAUDIN ALAIN
IPC: G01C19/04
Filed: 1976-11-30
Abstract: In a gyroscope with two sensitive axes the inertia wheel is submitted to aerodynamic forces due to interaction with the support structure. Resultant parasitic torque is eliminated by modifying its axis to become coaxial with the rotational axis of the wheel. A gyroscope comprises a motor (11) which rotates an inertia wheel (12) via a Cardan coupling (13). Detectors (16) sense the position of the wheel relative to the support structure (15). Parasitic torque effects are modified by modifying aerodynamic forces by making the inner face (15a) of the support structure inclined. This part (18) of the structure is removable from the fixed part (17) of the structure.

Title: Turbine driven by air or water - has stationary conical inlet piece to concentrate fluid entering to increase output
IPC: F03D1/00
Filed: 1977-05-02
Abstract: The turbine has an outer casing with a conical front piece open to the wind. This leads to the throat of a venturi. An impeller with axial flow blades (23) rotates within the venturi. A cone on the front of the impeller is fixed and carries stationary guide vanes (20). It forms the inner surface of an annular inlet passage of which the casing cone is the outer surface. This guides and concentrates the wind to increase the power of the turbine. The tailpiece of the casing downstream of the impeller is a divergent nozzle. The flow of wind produces a depression in this which increases the flow through the turbine. A similar turbine can be used with water instead of air.
