Patent FR-2267453-A1 (FR)
Title: Safety device for diesel engine driven plant - has electro-magnetic valve shutting off fuel supply in emergency
IPC: F02M63/02
Filed: 1974-04-09
Abstract: The diesel engine fuel system consists of a fuel tank, a filter, an electro-magnetic valve and the fuel pump. The electro-magnetic valve is held in the open position when energised with current from the battery via the relay and terminal. Three sensors sense the engine temperature oil pressure and any required condition of the plant driven by the engine. In the event of a dangerous condition arising, the sensors transmit a signal which operates the relay which in turn opens a switch causing the valve to close and shut off the fuel supply. The device is particularly useful when driving irrigation pumps and operates when the water pressure fails.

Title: Counter sink tool for workpiece spot facing - has drive and cutting force transmission by radial projections mounted on carrier
IPC: B23B31/113
Filed: 1974-04-29
Abstract: The countersink tool has an elongate carrier on the lower end of which countersink is mounted by the reception of the carrier in a circular bore of the countersink which extends into a cavity provided with two axially extending driving surfaces. The carrier has two radial projections each of which is provided with a coacting surface lying in a contact with the driving surface when the countersink and carrier are in the operative position. The axially extending driving surfaces are positioned in non circular cavities adjoining the receiving bore, and, when in the operative position, each drive transmitting projection should lie against its respective cavity bottom to transmit axial cutting forces.

Abstract: A collapsible table eg. an ironing board has legs which are pivoted together in an X-configuration, the upper end of one leg being pivotally secured to the table and the upper end of the other leg having a cross member which is located in a channel piece attached to the table. The channel piece is slideable on a slideway secured rigidly to the underside of the table and a pivoted handle on the channel piece, controls a pin which locates in holes in the slideway so that as the channel piece is moved along the slideway to adjust the height of the table the pin can be located in a hole to fix the channel piece in position. The arrangement is simple and securely locks the table at a required height.
Patent FR-2288211-A1 (FR)
Title: Window or door frame water drainage - using porous plug or valve in drain passage
IPC: E06B7/14
Filed: 1974-10-17
Abstract: The device is for draining off water caused by condensation and seepage from wood or metal door and window frames at the same time preventing air from penetrating from the outside. It consists of a plug of porous matl. placed inside the holes which is normally provided in the sill of the frame. The water collects in channels and then drains through the hole containing the plug by a process of capillarity. The presence of the material in the hole prevents outside air from entering. Alternatively a valve may be placed in the drain hole.

Title: Device for automatic dimension control of extruded blanks - has adder coupled to blank width measuring appts. and motor driving extruder screw, controlled by amplified-converter
Inventor: BORISOV V A
IPC: B29C48/92
Filed: 1977-03-31
Abstract: A device for automatically controlling the dimensions of an extrudate includes a means for measuring the blank width, a third added coupled to the measuring means and to a blank dimension presetting means. The output of the third adder is fed to an amplifier converter to a fourth adder in addition receiving an input from a compensator unit and feeding an output signal to a non-linearity unit. The non-linearity unit is connected via a switch to a second adder which also receives input from a sensor measuring the speed of the extrudate draw-off motor. The switch alternatively connects a draw-off speed presetter to the second adder. The output of the second adder is fed via an amplifier to the draw-off motor. The speed of the screw driving motor is sensed by a sensor and the resultant signal is fed to the non-linearity unit, to the compensator unit and to a first addler. The first addler also receives input from a screw rpm presetter and directs its output to an amplifier and then to the screw driving motor. In use the rpm of the screw is set by the presetter and the draw-off speed is automatically set to match it by using the switch to connect the non-linearity unit to the second adder.
