Title: Fire protection valve for air conditioning duct - has flaps held open by fusible clip and closed by torsion spring
IPC: F16K17/38
Filed: 1975-07-01
Abstract: The fire protection valve consists of two semi-circular flaps (5, 6) mounted on a common hinge pin (3). The hinge pin is fixed at two diametrically opposite points of the air conditioning duct (1) adjacent to the valve seat (2) formed by swaging the circumference. The flaps are held open by a clip (15) formed by brazing together two L-shaped members (16, 17). The flaps are held in the central position by a transverse pin (4). When the temperature in the duct rises above the melting point of the brazing metal, the torsion spring mounted on the hinge pin (3) is able to close the flaps (5, 6) and so prevent the spread of fire.

Title: Electric sleep inducing apparatus - has impulse generator supplying two leads each ending at electrodes
IPC: A61N1/34
Filed: 1976-02-13
Abstract: The electric sleep-inducing apparatus has a single impulse generator directly supplying two leads each ending at electrodes. Each lead has a source of constant current, i.e., its intensity is virtually independent of the load. The two sources are independent of each other. The two leads may be symmetrical, and the generator may produce voltage impulses of variable amplitude. The current intensity from each source is proportional to the voltage transmitted by the generator. The impulse frequency may also be adjustable, as may the duration of the impulses transmitted.

Title: Fertiliser spreader with distributor ramps - has wire holding up ramps and adjustment cable over roller
IPC: A01C15/18
Filed: 1976-03-10
Abstract: The distributor of the fertiliser spreader consists of a left hand and right hand ramp (1) which when operating are in a position vertical to the direction in which the support chassis (3) is moving; when not operating, the ramps are flapped up to both sides of the support chassis. Each of the ramps (1) has a conveyor for the product, in the form of Archimedes screws, with an outer pipe with outlet holes in. The distance between two adjacent outlets is in proportion to the throughput rate of the product. The bottom of the ramps (1) have slide pieces on the edge of the line drawn through the outlet holes, and which can be moved parallel so as to close, partly or completely, the outlet holes. Attachments fix the slide pieces in position. Each ramp (1) is moved from an operating to a non-operating position by means of an arm (13) which is at right angles to the main axis of the ramps. One end of the arm is hinged to a universal joint, and the other end rests on a bar fixed to the chassis with roller in between.
Patent FR-2343536-A1 (FR)
Title: Internally cooled continuous casting roll - with metal sleeve gripping roll body and blocked by abutments
Inventor: DURINCK RENE
IPC: B22D11/128
Filed: 1976-03-12
Abstract: The roll has an outer sleeve mounted between two axial abutments integral with the body of the roll. The sleeve which is made of a metal with a high YS (elastic limit) and which has a thickness of approx. 10% of the dia. of the body and a length of ca. 80% of the distance between the journal bearings grips the body along at least part of its length with a cold fit sufficient to allow transmission of the drive torque of the roll to the sleeve and to leave when heated a residual tightness. The axial abutments are positioned in contact with the ends of the sleeve without gripping nor allowing any clearance when cold so that each end of the sleeve is immobile w.r.t. the cylindrical body of the roll in the gripping zone. Since a high YS metal is used for the sleeve the thermal and mechanical stress do not result in plastic deformation of the sleeve. As the sleeve is not deformed fluid tightness is ensured and there is no loss of coolant. No welding is necessary and difficulty weldable materials can be combined.
