Title: Drilling slide for use in mine - has truck thrust along rails by two double acting rams between truck and girder
IPC: E21B19/086
Filed: 1975-06-10
Abstract: The slide is for drilling holes when mining, having a girder with guide rails for a travelling truck forming the drilling unit. The truck is thrust along the rails by two double acting rams with parallel axes and joined rigidly together by their bodies. The rods of the rams extend in opposite directions, one being coupled to the truck and the other to the girder. One of the rods can be secured to the forward end of the girder. The sum of the strokes of the two rams can be equal to the girder length less that of the truck. This gives the maximum distance of truck travel, without the rams protruding beyond it.

Title: Vertically travelling circular saw - automatic brake mechanism for rollers supporting workpiece
IPC: B27B5/07
Filed: 1975-09-02
Abstract: In the machine, a flat workpiece (9) lies just-out-of-upright against a frame (1) while it is cut by a circular saw (5) which is carried on a vertical guide (2). The workpiece rest on rollers (8, axles through 6) at the foot of the frame. These rollers have automatic (instead of manual) brakes to eliminate any possibility of the workpiece moving under the saw. To this end, the electromagnet (22) which operates the brakes releases them only when a microswitch (23) has its contact knob (24) depressed, i.e., only when the saw is moved back away from the workpiece (knob depressed by 25). The brakes envisaged are simple friction brakes, operated from a common lever and individually adjustable to give the same braking pressure.

Title: Mechanised removal of marc from winemaking vessel - by remote controlled trolley connected to external vacuum system
IPC: C12G1/00
Filed: 1976-07-02
Abstract: Machine is for extracting marc from a fermenting vessel used in winemaking. The machine comprises a remote-cont-rolled, powered trolley which travels into the vessel. The trolley is furnished with a powdered rotor which chops up the marc and feeds the fragments to a suction head on the trolley. The suction head has a flexible duct connected to a vacuum system outside the vessel. When withdrawn from the vessel, the trolley pref. resis on a vertically displaceable platform which is pivotally attached to and mobile with a ground mounted carriage. The vacuum system, comprising cyclone receiver and suction pump, is pref. also mounted on the carriage conveyor to discharge cycloned marc and a separate outlet channel from which juice is recovered. Used for mechanised removal of marc from winemaking fermenting vessel. Eliminates need for an operator to enter the vessel. This can entail risk of CO2 asphyxia, even after waiting period, which is not longer necessary. The ectn. of marc is rapid, easy and does not hinder the production of high quality wine.

Title: Impregnating yarn with fluid - by passage through bath and feed tube, along which fluid flows caused by movement of yarn
Inventor: MAZIERES YVES
IPC: B29C55/00
Filed: 1976-07-23
Abstract: A textile yarn is impregnated with a fluid dressing agent by being advanced through a batch and into a tube whose inlet communicates with the bath. The tube is pref. upwardly inclined and the outlet of the tube is situated adjacent a collection tank. The movement of the yarn through the bath and tube caused the dressing agent to flow along the tube and pour into the collection tank from where it is fed back to the bath. The method is esp. used for impregnating pneumatic tyre reinforcing cord with adhesive. Aegradation of the yarn and dressing agent is eliminated and there is reduced pollution. The quantity of dressing agent used and power consumption is reduced compared with conventional devices.

Patent FR-2341028-A1 (FR)
IPC: E05F3/04
Filed: 1977-02-11
Abstract: During the opening of a door, a closing element (17) connected to the door leaf pushes a piston (16) inwards in the cylinder space of a first constructional unit (10) attached to the door frame. The piston (16) presses on a hydraulic pressure medium (13) which continues through the first constructional unit (10) and through a connecting conduit (12) into a second constructional unit (11). Mounted in the second constructional unit (11) is a second piston (14) which separates the hydraulic pressure medium (13) from a space containing pneumatic pressure medium (15). Thus, during the inward movement of the first piston (16), the second piston (14) is also moved inwards via the hydraulic pressure medium (13) and the pneumatic pressure medium (15) is compressed. After the movement of the door has ended, the pressurised pneumatic pressure medium (15) pushes the first piston (16) together with the closing element (17) outwards via the hydraulic pressure medium (13), thus causing the door to close again automatically.
