Patent FR-2481363-A1 (FR)
Inventor: BALOIU SERGIU
IPC: F02B23/04
Filed: 1981-04-24
Abstract: The invention relates to a divided combustion chamber for internal combustion engines with compression ignition or spark ignition, the (air-fuel) mixture homogenisation being improved and the controlled air movement intensified in the inlet-compression and combustion phase. The division of the combustion space into two chambers is achieved in that as the piston approaches a part coaxial with this and fixed to the cylinder head, which part has the form of a roller element and on its outside carries projections in the area of the inlet valves, an annular duct forms between the two combustion chambers, the cross-section of the duct having the contour of a convergent-divergent nozzle (diffuser). The said projections in the area of the inlet valves have the advantage both of introducing the intake flow at a tangent to the cylinder and of intensifying the controlled movement of air towards the end of the compression stroke and likewise of improving the combustion by advantageous kinetics of the flame cores.
Patent FR-2504832-A1 (FR)
Inventor: DUMONT ROBERT
IPC: B23B31/16
Filed: 1981-04-29
Abstract: The invention relates to an arbor with at least two jaw-carrying sliding pieces which can be simultaneously moved radially from inside or from outside to mount a workpiece to be machined. The invention is distinguished by a reversible drive device (1 to 5) for tightening or releasing each screw (9) in each sliding piece (14). During a first phase, a piston acts directly on the base of the cylinder which is arranged opposite the end of a nut (10) and is then locked against rotation and is held in contact with the sliding piece (14) when the screw (9) is screwed by means of the drive device (1-4). In a second phase, the piston acts indirectly via a pressure fluid on the same base of the cylinder (1). The surface of the nut (10) is acted upon directly for the displacement of the sliding piece during the preloading from inside of a workpiece to be machined, the nut (10) being locked against rotation by the piston (16). The piston (16) exerts a fluid pressure on the base of the cylinder, which is located opposite that of the nut (10), an additional device being provided in order to make the fine adjustment of the final clamping position of the jaws by hand.

Title: Impact fuse for non rotating projectile - has four safety locks to give high security with manual over ride for three
IPC: F42C15/184
Filed: 1981-05-18
Abstract: The impact fuse is for a non rotating projectile. It has a piston and pin (23,4) and a radially moving primer. This acts by timer (11) action, set in motion by firing the projectile. The mechanism includes four safety locks. The first (13) is inertia released on projectile firing. The second (12) locks the first (13), and the third (17) locks the firing pin with manual control (2) for unlocking. The fourth (18) cannot be overridden and locks the manual lock at the end of the primer movement. The second lock is a turning cap forming a dome, covering the fuse.

Patent FR-2509380-A1 (FR)
Inventor: REDELE JEAN EMILE AMEDEE
IPC: F02M31/16
Filed: 1981-07-08
Abstract: The object is to provide an apparatus for easily starting up the engine under cold conditions and avoid any crystallization of the Diesel oil under these conditions. The apparatus comprises a heat exchanger (2) heating the fuel by means of a heat-carrying fluid, such as the cooling liquid of the engine, when it has reached a predetermined minimum value. A reserve supply of hot fuel (1) is connected to the exchanger (2) and comprises at least one auxiliary source of heat (20). The reserve supply of hot fuel is connected to an injection pump (8) and also to a thermostat valve (11) inserted in a return pipe (10) of the injection pump (8). This valve (11) connects the return valve (10) directly to the reserve supply of hot fuel (1) below a previously fixed temperature of the latter or when the temperature of the fuel is higher than the previously fixed temperature, it connects the return pipe (10) to the main fuel tank (13) which is itself connected to the heat exchanger.

Title: Continuous operation, thin walled, tube-drawing bench - has drag chain assembly with laterally settable stop lug in one chain link
Inventor: AKCHURIN R Z
IPC: B21C1/30
Filed: 1982-03-12
Abstract: The continuous operation drawing bench produces thin walled tubes using a link drawing material. The bench has a drawing die and two parallel drag chains (21,22) fitted in front of the die and comprising pressure elements. The drag chain has in one of its links a stop lug (24) which is movable in a direction perpendicular to the drawing axis. This design allows continuous feed of the blank and at the same time the magnitude of the penetration force of the blank through the die is reduced. The stop lug is a lever (39) swivelling around a joint (38) with a spiral spring (40). The swivel motion of the arm is controlled by an axial cam on the face surface of the driving sprocket disc (43).

Inventor: BAUER KARL-HEINZ
IPC: H03J5/12
Filed: 1983-05-27
Abstract: The multiple push-button unit for television receivers, shown in Figure 1, consists of two housings (1) in which several push buttons (16), which mutually trigger themselves by means of a swing-loaded locking rail (7), for switching on channel memory devices are displaceably arranged. The tuning and the frequency band selection is effected with the aid of rotary push buttons (12). To save cable trees and additional printed circuit boards, the push-button units are to be arranged in a row next to one another not with the wide side but with the narrow side since these can then be soldered directly into a large printed circuit board which is in most cases required in any case. For this purpose, corresponding soldering tabs protrude at the bottom from the housings (1). Both the locking rails (7) and the housings (1) have appropriate connecting means (20, 24, 30 and 33) for being arranged in a row next to one another.
