Title: Automatic purificn. pit for sewage - with Pelton wheel drive for aerator and comminutor with no electrical installation
IPC: C02F3/12
Filed: 1975-07-10
Abstract: Biological purifcn. pit for sewage, coming from a small number of houses, is operated by means of activated sludge; it comprises a cylindrical tank with a vertical axis and a central orifice connected to the conduit leading to a lateral tank. The principal tank is closed by a lid supported by an aerating ring of porous material. Both tanks are closed by lids. The effluent arrives by the conduit and flows into the perforated basket fitted with a helix which acts as a comminutor for the solid particles. The helix is keyed to the vertical shaft which also drives the surface aeration turbine; this emulsifies the air and facilitates the rapid development of the aerobic bacteria. A driving turbine is also keyed to the shaft; it is driven by a jet of water under pressure from the nozzle and is of the Pelton type. The orifice is closed by a porous concrete disc; partly purified water passes through to the conduit where aerobic action continues until the anaerobic stage is reached when the water passes through the disc into the lateral tank. The base of the latter is divided by porous concrete transverse walls. The purified water finally leaves by the outlet. Appts. operates automatically without any electrical installation or motor. Each distribution of water under pressure not only drives the turbine but also the comminutor and the aeration turbine. The water thrown from the Pelton wheel rinses the walls of the tank and at the same time entrains oxygen.

Title: Cylindrical gate valve with lateral sealing movement - has eccentric mounted operating arm with detent connection to drive arm
IPC: F16K5/18
Filed: 1975-09-05
Abstract: The gate (14) of the fluid control valve is part cylindrical and rotates inside a cylindrical housing (1) connected to inlet and outlet manifolds (1b, 1c). As the gate is rotated through a quarter turn by a handle (7) it covers or uncovers one of the ports (1b). An arm (8) bent at a right angle and carried on an eccentric (4b) on the drive shaft (4) rotates of the gate. A subsidiary lever (9), integral with the shaft, actually rotates the valve arm (8), which is freely mounted on the eccentric. This arrangement ensures that the gate is firmly in contact with the seat when closed and pressure is relieved during operation.

Title: Hydraulic motor with oscillating and rotating cylinders - has central toothed wheel driven by rods projecting from surrounding cylinders
Inventor: PINSON CLAUDE MAURICE
IPC: F01B5/00
Filed: 1975-10-17
Abstract: The piston and cylinder assembly (7) consists of two cylinder blocks (12) with a common piston. This piston has a central shaft projecting at right angles to the piston axis and forming a pivot for the assembly (7). The cylinder blocks (12) are joined by plates (17) carrying forks (18) provided with rods (19). The rods (19) connect with a similar assembly (7) on the other side of the toothed wheel (6). When fluid is supplied to the assembly (7) the cylinder blocks oscillate and simultaneously rotate. The rods (19) then impart a rotation to the wheel (6) which rotates through an angle equal to two pitches of the teeth (39) for each rotation of the assembly (7). A number of assemblies (7) are fitted around the wheel (6).
Patent FR-2289833-A1 (FR)
Title: Plastic hose has saw-like undulations with unequal sides - longer side has inward concavity, the two sides enclosing angle of 100 degs
IPC: F16L11/11
Filed: 1975-10-29
Abstract: The feature of unequal sides of the undulation and with the longer side having an inward concavity, ensure that the pipe, when pushed together, remains in this position, showing an apex of 10 deg.. The ratio of the non-undulated outside diameter to the outside diameter of the undulated part is 1:1,25. The outside diameter 14 and the inclination 16 of the undulation have a ratio of 2,5:1. The pipe can be pushed together to a length, which is 1/5-1/7 of the original length, resulting in a reduction of storing space. Once the undulated part is pushed together, the pipe can be bent and the bend stays in the required position. The pipe does not need any reinforcements or inserts to keep the bend in the required radius.
Patent FR-2291071-A1 (FR)
Title: Multi control system for train brakes - with balancing throttle valves to ensure similar operation of different controls
IPC: B60T15/16
Filed: 1975-11-14
Abstract: The train is fitted with different brake controls spaced about the train, in different control panels, or control cabs. The controls operate the brake using a main pneumatic relay controlled by a control pressure in the control valves. In order to balance the separate controls w.r.t. their control line volumes etc. special throttle valves are fitted to each panel. The driver merely moves the brake lever to the first setting to obtain similar braking effects from any control point. The system operates purely pneumatically without a separate power source.

Title: Radio control system for percussion mechanism actuation - uses short wave transmitter receiver units which interact with each other to actuate percussion device in firearms
IPC: F41A19/68
Filed: 1975-11-17
Abstract: The firearms percussion mechanism control system uses at least two radioelectric units. Each one of them has a short wave transmitter (E1, E2). The wavelength of each transmitter is different from that of the other. Each unit has a short wave reciever (R1, R2) adjusted to detect the radiations transmitted from the other transmitter. The system has circuit (C1) designed to put simultaneously its transmitter and receiver in the operating state. A switch (I1, I2) actuates the closing of another circuit (C2) connecting each unit to a control unit of one of the percussion mechanisms which the system is to trigger when its transmitter and receiver operated simultaneously. The switch is actuated by the receiver at the moment of detection of the waves emitted by the other unit.

Title: Manual pushbutton for timepiece mechanism - has conical face adjacent end of pushbutton shaft to retain shapt in guide tube
IPC: G04B37/10
Filed: 1976-01-26
Abstract: The manual push-button, for a timepiece mechanism, has a push-button shaft (2) enclosed by a guide tube (3) inserted through the housing of the timepiece and acted on by a biasing spring (4). The push-button head is fitted to one end of the shaft (2), while the other end is formed with a truncated conical surface (6) with a larger initial diameter than the internal diameter of the guide tube (3) at the bottom end. The push-button head and the spring are fitted to the shaft (2), before this is inserted in the guide tube (3), the shaft (2) then being forced downwards, so that the conical section (6) is pushed through the bottom end of the guide tube. The edge (t) between this section and the upper part of the shaft (2) then acts against the bottom of the guide tube (3), to limit the upwards displacement of the shaft (2).

Title: Initiating device for projectiles with transverse charge - has wireless or optical system used also for projectile steering
Inventor: KULLER NILS-ERIK
IPC: F42C13/02
Filed: 1976-03-23
Abstract: The initiating device is used for a projectile which has a transverse explosive action. The projectiles include also rockets and naval warfare means such as torpedoes and rotation stabilised and nonrotating projectiles. The projectile travels past the target and is exploded at a point where its effect is maximum. This ensures that the target is attached at its more vulnerable parts such as the roof or sides of a tank. The projectile can be exploded by a wireless signal in the form of electromagnetic waves. Alternatively light signals can be used which can also be used for projectile guidance. For guidance purposes four light detectors can be fitted on the projectile tail fins. The warhead can be a transversely mounted hollow charge whose line of action is at right angles to the projectile axis.
