Patent FR-2231800-A1 (FR)
Title: Textile fabric stretching device - senses oblique-curved weft misalignment, correcting by changing tension
IPC: B65H23/038
Filed: 1974-04-25
Abstract: A stretching device for knitted or woven fabric in its finishing stage includes an oblique correction device and a curved correction device for the weft threads. A feeler detects any misalignment between weft and warp threads and corrects this by varying the longitudinal tension. The output roller is driven at constant torque, exerting a fixed tension, independent of tension changes in the fabric by the correctors. This system compensates for any tension changes caused by the correctors so that the feelers can be arranged behind the tensioning frame. The fabric thread alignment is thus checked subsequent to the stretching process and the results are more uniform.
Patent FR-2233234-A1 (FR)
Title: Oven for fitting heat shrink caps on to bottles - comprising a recirculating hot air tunnel for uniform heating
IPC: B67B5/03
Filed: 1974-06-11
Abstract: Heat shrinkable caps are placed over the tops of bottles which then pass through a tunnel where a current of hot air is circulated past the caps. The tunnel should have hollow walls with one or more jets directed down on to the crown of the cap and with orifices in the sidewalls approx. level with the base of the cap to collect and recirculate the air flow. The tunnel casing may incorporate the necessary blower(s) and heater(s). The enveloping air flow promotes more uniform heating and shrinkages of the caps than use of static radiant heaters and is less sensitive to variations in the size and height of the bottles and their caps. Recirculating system is thermally efficient.

Title: Motor-driven striking tool - drive piston has valve with helical spring in drive piston of concrete processor
IPC: B25D11/12
Filed: 1975-01-10
Abstract: The striking tool has a drive piston, hinged to a crank drive, which vibrates a striking element, via a rhythmically compressed air pad with the element striking the tool in the sequence of the crank drive. To replace lost air, the pad is connected to a housing space via a valve, which opens during a return stroke of the working piston, as soon as the pressure difference between the spaces separated by the valve and low pressure in the air pad, exceeds a predetermined limit. The valve is controlled by the low pressure in the air pad, and is positioned next to the pad, in the front face of the drive or striking piston. The flow through the valve is dampened, so that the striking piston is sucked along by the returning drive piston.

Title: Security tumbler lock mechanism - has additional angularly displaced radial bores with sprung tumblers shaped as a pin with bore diameter sized head
IPC: E05B27/00
Filed: 1975-05-30
Abstract: The security lock mechanism has a rotating cylinder (2) within the stationary cylindrical body of the lock (3). Sprung tumblers of different heights (5) lie in radial bores in the stator, and corresponding counter-pins lie in the key slot in the rotor.

Title: Tunnelling system travelling conveyor - has framework spanning unlined zone, carrying discharge conveyor, track conveyor and formwork conveyor and positioner
IPC: E21D9/12
Filed: 1976-04-13
Abstract: A tunnelling system employes a framework mounted on wheels, with the end remote from the face being cut, and supported on the part of the tunnel which has been lined. The other end, near the excavating machines is supported by wheels which can travel on rails mounted on blocks. Thus the region to be lined is spanned by the framework. The framework is used to carry wagons to remove the cut material, and convey the concrete lining material and the framework. The rails at the cutting end are carried by a monorail conveyor over the unlined region. The conveyor for cut material is a belt conveyor above this level, extending end to end, travelling on rollers. The trolley carrying the formwork travels on rails above this level.
