Patent FR-2156454-A1 (FR)
Title: Disinfecting appts - for rooms and hospitals
IPC: A61L2/20
Filed: 1971-10-20
Abstract: The device consists of a combination of formaldehyde generators, a neutralising device for these vapours, a steam boiler, a heater regulated by a thermostat, and a device for drawing-in the ambient air and dispersing the air charged with steam and formaldehyde vapour in a regular, homogeneous and constant current. The different phase of the disinfecting operation are controlled by a programmer coupled to a luminous chart.

Title: Modified polypropylenes - grafted with cis-unsatd alicyclic carboxylic acids for improved adhesion to inorganic fibres
IPC: C09D151/06
Filed: 1972-03-15
Abstract: Crystalline polypropylene and one or more alicyclic carboxylic acids with a cis double bond in the ring or their anhydrides, are heated together in presence of a substance producing free radicals. Adhesion to fibres esp. to glass, and to metals is greatly improved by the grafting process. Fibres coated with the modified polypropylenes in soln. show better adhesion to polyolefines. The modified polypropylenes can be readily coloured, esp. with basic dyes, printed and plated, without roughening the surface.

Patent FR-2247664-A1 (FR)
Title: Articulated compensation structure link - has two toothed segments at ends of similar tubular rods
IPC: F16L51/03
Filed: 1974-10-11
Abstract: The compensation link is of articulated form and is especially for structural engineering applications, particularly bridges. The link is in the form of a double arm of tubular rods with ends flattened and cut out to form mating teeth in the shape of arcs of circles, the radii of curvature being less than the diameter of the members. Tractive force along the army towards the pivot can be relived by a lateral movement between the curvilinear teeth, thereby permitting small changes in length to be accommodated without the build up of large shearing forces. The circular arcs of the joint mating surfaces are blended together to form a sinusoidal profile (37, 38).
Patent FR-2294290-A1 (FR)
Title: Thermal and sound insulating false ceiling - with lower layer suspended elastically from upper layer
IPC: E04B9/00

The upper layer is typically formed by a plate nailed to a ceiling and supporting blocks on its undersurface. The blocks have openings containing springs whose upper ends are anchored in the tops of the blocks. The lower ends of the springs are anchored in the bottoms of supporting blocks on the upper surface of a plate forming the lower layer of the false ceiling. The lower plate is thus suspended by the springs and spaced from the upper plate. The air layer may contain cable service line ducts.

Title: Plastering tool using rollers - has plastics film over rollers supporting charge and applying it evenly to surface
IPC: B05C17/02
Filed: 1975-02-25
Abstract: The plasterer's tool consists of a frame with its base (2) projecting outwards to form a gripping handle and carrying a front and a rear roller (3), from which plastics sheet (4) is unwound. The sheet supports a charge of plaster (6) and thus the plaster is evenly applied to the wall. Two side plates (1a) which carry the rollers have a raised portion (8) which prevents the charge from spilling sideways. A flat member (7) between the rollers support the plastics sheet and the weight of the charge. The tool is then moved vertically down the wall for the plaster to be transferred evenly onto its surface. A peg extends outwards from each side plate, so that these can travel in slots in a vertical frame supported against the wall.

Title: Energy consumption saving switch - connects diode between AC mains and lamp and heater
IPC: H01R33/945
Filed: 1975-03-06
Abstract: The circuit is designed to saving on energy consumption by and increase the working life of an electrical consumption unit such as a filament lamp or a resistance element. Typical applications are street lights in positions where other illumination is available, a reading lamp in a room where other occupants watch television, or a porch light where partial illumination is acceptable most of the time. A diode (7) is connected in series with the lamp or resistor, (9, 10) so that when connected to a.c. mains (1, 2), power is supplied during alternate cycles only. A two position switch (11, 12, 13, 14, 15) enables the diode to be by-passed so that full power is available for maximum illumination or heating.

Title: Expandable jewelled finger ring - has two semicircular segments joined by hinge and fastener with hooked spring dowel sliding in slotted socket
IPC: A44C9/00
Filed: 1975-03-11
Abstract: Two semi-circular segments form the ring. A hinge pin which is parallel to the major ring axis effects on of the joints between the segments. The other joint between the segments is made by a circumferentially extendable fastener. The fastener may use a spring dowel (12) which projects longitudinally from the end (6) of one of the segments and slides into a socket (19) in the end (8) of the opposed segment. The spring may terminate in a cross bar (23, 24) which engages closed slots (15) in the lateral walls of the socket. The slots serve to retain (21) the spring (12) by the cross bar (24) when the ring is extended and effect locking when the ring is closed.
