Title: Toy animated by effect of gravity - has a series of plates assembled one above the other by threads
IPC: A63F9/08
Filed: 1974-02-25
Abstract: When the upper plate held in the hand is pivoted by 180 deg. the other plates pivot in turn giving the effect of a cascade. The plates are in two parts (7, 8) which are assembled two by two by clipping them together. There are triangular grooves (15, 16) parallel to and near the edge of the plates in which the threads (20, 21) run. The inclined planes of the grooves centre the threads, so ensuring a good superposition of the plates. The two threads cross each other between the plates and can be one continuous thread.

Title: Building component clamping coupling - has component expanding on tightening in relation to anchoring devices
IPC: E04B1/21
Filed: 1974-03-18
Abstract: The coupling is particularly in the form of a bolt in the join between the components, accessible from outside to allow tightening by a tool, and working in conjunction with anchoring devices in both components. It includes a component (20, 21) expanding to an increasing degree on tightening in relation to the anchoring devices. Increasing expansion of the components (1, 2) brings them closer together in an direction at right angles to the join (5) and at the same time produces a locking effect at right angles to the direction. The coupling can have an extension into an opening (16) in a component parallel to the adjacent ones (1), a locking device (18) being provided in the opening working with the coupling.

Patent FR-2315287-A1 (FR)
Title: Safety lowering device for people or loads - has cable drum braked when gas ram pressure equals liquid ram pressure
IPC: A62B1/12
Filed: 1975-06-27
Abstract: The braking mechanisms of the device comprises two interconnected cylinders, one of which is filled with a liquid and the other with a gas. Lowering is performed by unwinding a cable or rope from a drum. Rotation of the drum causes, by means of a gear system, the piston of the cylinder filled with a liquid to move, thereby pressing liquid into the second cylinder and moving the piston of this cylinder against the mounting counter pressure of the gas cushion. When this counter pressure equals the force exerted on the piston of the first cylinder by the cable load the unwinding stops. By providing the device with an additional bearing and means for selectively coupling the cable drum to said gear system, the device may be used as a safety device when working at high heights.

Title: Automatic moving publicity display panel - has two drums onto which is wound display band with method for tensioning band and halting movement to exhibit complete display
IPC: G09F11/22
Filed: 1975-07-21
Abstract: The display panel has a series of parallel drums (3a,3b) mounted in a housing (1). One feeds and the other receives and of vice versa. A display band is wound on each drum (3a,3b) and can be transferred from one drum to the other. The system has means (4) for driving a drum when it is the receiver. A method is included for stopping the movement of the display for a determined period, so that at each stop, a complete display appears before an observation window of the display panel. The panel has a method for tensioning the display band. These means brake the feeding drum during the movement of the display band and reverse the movement of the drum when the band movement stops.

Title: Connecting tubes for irrigation installations - has guide tube with telescopic tube and with widened lower end and scraper rings
Inventor: MEERTZ JOSEF
IPC: B05B15/60
Filed: 1975-09-16
Abstract: The tubes are connected to the ends of the underground mains pipes of an irrigation system when the surface pipes have been removed in order that the soil may be worked. Under pressure from the water these tubes push their way to the surface so that they can be easily located when it is desired to set up the system once again. The tubes comprise a guide tube (1) which is connected to the irrigation mains pipe, in which slides a telescopic tube (2). The end surface of this tube is at right angles to the direction of flow of the water and is of such a size that the pressure of the water upon it overcomes the friction of the telescopic pipe in the guide pipe, and the former is thus forced to the surface.
