Title: Automatic positioning of cinema screen curtains - controlled from magnetic signals on film through motor control circuit
Inventor: DUTRIEZ RENE
IPC: A47H5/032
Filed: 1974-06-14
Abstract: The screen curtains in a cinema are set to positions which depend on the type of projection for instance normal panoramic or cinemascope. The curtains are automatically controlled from the projector and are repositioned when misalignment occurs. Each screen curtain is repositioned by cables operated by an automatically controlled motor. Magnetic signals on the film dictate the opening of the curtains controlled through relays whose contacts are in circuits comprising curtain format relay windings with indicator lamps. Relay contacts connect manually adjusted reference potentiometers to a detector comparator which also receives a signal from a potentiometer signalling directional movement of the motor. Outputs give directional control signals to power relays which power the motor in the desired direction.

Preferably the drive element consists of an opening and shutting member of identical design, both carrying the recess engaging pins.
Patent FR-2243365-A1 (FR)
Title: Universal joint for connecting tubular beams - has spring loaded axially movable cross head with locking pin slots
IPC: G01C13/00
Filed: 1974-09-04
Abstract: The cross head of a universal joint carries four slider blocks on pivot pins. The axial end faces of these blocks are spring loaded by identical compression springs. When the beams exert no tensile or compressive load on the slider blocks, the springs keep the cross head in its mid-position. The freedom of movement of the universal joint is therefore unrestricted. When an axial load compresses one set of springs, locking pins attached to the beam fittings engage in matching slots in the cross head. This stops the universal joint from moving in either plane and also from rotation.

Title: Vacuum cleaner with air recycled to suction nozzle - has return tube arranged for discharging around nozzle or concentrically through nozzle
IPC: A47L5/14
Filed: 1975-02-17
Abstract: A vacuum cleaner has a cylinder (1) with a collector bag (11) at the front, the fan (7) immediately behind and a discharge pipe (12) at the rear. This pipe also branches, with a control flap (14) at its junction with the branch pipe (13) and forming a hairpin bend, with a return tube running alongside the cylinder and terminating in a nozzle (17) around the suction nozzle (5) at the front. The suction nozzle has a resilient flap (6) at its junction with the cylinder, which lifts when the fan starts. The air recycled through the return tube (16) passes through a restricted annular gap (20) around the suction nozzle, so as to loosen particles from the surface being cleaned, so that they are quickly passed to the suction region. In an alternative design recycled air is released through a pipe passing through the centre of the suction nozzle.

Title: Unstable operation detector for axial or radial ventilators - using a leaf spring monitor with electrical attachments operating rectifying mechanism
IPC: F04D27/02
Filed: 1975-03-21
Abstract: To detect unstable ventilator operation has a leaf spring mounted on a metal block projecting at right angles into the flow area of the ventilator roughly parallel to the wheel axis. A tangential force will cause the spring to swing (dotted lines). A wire strain gauge attached to the spring will give an electrical signal which is boosted and used to rectify the fault by either operating a relief valve, or adjust blade angle or reduce rotor r.p.m. The detector may be a test measurement transducer which incorporates tensioned measuring strips. A resilient distance piece may be fitted between the housing of the ventilator and the leaf springs.

Title: Loudspeaker diaphragm mountings - giving independent three=dimensional adjustment using nylon filaments and silicone rubber strip profiles
Inventor: BERTUOL BERNARD
IPC: H04R7/20
Filed: 1976-11-04
Abstract: The radial alignment of a loudspeaker diaphragm is controlled by a mounting comprising tensioned elastic filaments anchored at each corner of the speaker chassis and to the mid-point of each of the (four) edges of the diaphragm. The air chambers on each side of the diaphragm are divided by omega (OMEGA) profile strip seals of flexible material pref. silicone rubber, mounted between each edge of the diaphragm and the loudspeaker casing and not imposing any significant radial thrust. Axial location of the diaphragm is maintained by an electromagnetically located rod. Thus each component of the diaphragm location vectors can be separately controlled and adjusted to obtain a sonic balance. For a flat membrane with 600 mm sides and weighing 1240 g complete nylon filaments of 0.45 mm dia. were satisfactory for radial support.

Title: Accumulator plates secured by bonded plastic strips or wedges - to inhibit vibration within polypropylene battery cases
IPC: H01M10/16
Filed: 1977-02-25
Abstract: The plates of a wet accumulator are braced against vibration by rigidly linking the twin feet and the overhead tabs of each set of plates of like polarity using rods and/or strips of fused tapes to bind the edges of the plates or partitions. Ultrasonically welded polypropylene rods or cold-setting epoxy resin or hot melt polyolefin tape are used esp. for securing components in batteries with casings and partitions moulded from polypropylene and which cannot be securely located by conventional bitumastic or rubber strips. Wedges or tapered posts made by compressible material (e.g. expanded polystyrene) may be used to locate the groups of plates within the casing. The prolong the working life of batteries mounted adjacent to motors or other vibrating machinery.
