Patent FR-2489792-A1 (FR)
Title: Rail for packaging and display of e.g. hose clips - uses flexible clip retaining arm between outer arms whose ends are tied together to retain inner arm
Inventor: VUARCHEX MICHEL
IPC: A47F5/08
Filed: 1980-09-09
Abstract: The rail (1) is used in the packaging distribution and presentation of annular objects such as jubilee hose-clips (7). It comprises two parallel arms (3,4) with a gap (E) between them and with their leading ends connected (5). A third arm (6) is sited in the gap. The width (E) of the third arm (6) is not less than the distance between the outer arms (3,4) and is less than the greatest opening of a clip (7), the three arms coming together at the rear (11). The third arm flexes into an open position so clips (7) can be threaded onto it, and into a closed position with its leading end (10) retained by the outer arms. The fitting may be made from a single sheet of metal with the third arm (6) constituting a cut out tongue, and the trailing end turning down to form a hook (11).

Title: Ball game played by two people - has frame with each player holding handle with wires stretched between them off which ball bounces
IPC: A63B65/12
Filed: 1980-11-12
Abstract: The ball game is played by two people and uses two handles (2) with supple wires (3), which are strong enough to resist a human pull, stretched between them. The wires are separated by regular spaces that allow the ball to rebound when they are stretched but allow it to fall through when they are loose. The ball is a sphere with a dia. of 80mm and weighing 100 g. One handle is held by each player and the object is to keep the ball bouncing by keeping the wires taut.
Patent FR-2470317-A1 (FR)
Inventor: OBERDORFER HANS
IPC: F16K11/074
Filed: 1980-11-20
Abstract: The control-disc valve has a rotatable regulating disc (1) and a fixed disc arranged coaxially relative to the latter. The regulating disc (1) contains orifices (4, 5), one edge of each of which is at a variable distance from the disc centre. The fixed disc also contains, in addition to the conventional orifices (9, 10) in the form of a segment of a circular ring, an orifice (8) which is of special design. The individual orifices are connected partially to one another and partially to conduits leading to a hot-water mixing battery, to a hot-water store and to the cold-water feed conduit. As a result of the rotation of the regulating disc (1) relative to the fixed disc, the orifices (4, 5, 8, 9, 10) overlap to a changing extent and thus vary the temperature of the water outflow from cold to hot. The special shape of individual orifices makes it possible for the sum of the angles formed by the orifices to exceed 360 DEG , thus signifying a larger regulating travel.

Title: Motor-compressor group current circuit failure detector - has shunt resistance across internal motor switch for facilitating determination of switch state
Inventor: KARNS PHIL J
IPC: G01R31/02
Filed: 1980-12-18
Abstract: The motor compressor group has a motor supply circuit (10) which includes a series switch (24) in one of the supply leads (L3, L4, L6) between the motor (12) and the current source (L1, L2). This switch (24) is contained within the motor housing (26) and has a shunt circuit (25) across it provided by a resistor with a resistance of above 10,000 ohms. The state of the internal switch (24) can be determined without opening the hermetically sealed motor housing (26) by connecting the circuit (10) to a supply and measuring the current passed via the shunt to the motor (12) or by measuring the resistance of the supply circuit (10). The method allows a breakdown of the motor to be attributed to a faulty motor or to the series switch being left open.

Title: Geothermal heat recovery appts. - uses heat exchange tubes sunk in ground by ram driving string of tubes
IPC: E21B11/02
Filed: 1980-12-26
Abstract: Vertical heat exchanger rods are sunk in the soil to recover the geothermal heat by water passing down a central tube and ascending in the annulus between it and an outer tube. The inner tube is fitted with a drive point and at the rear end with an adapter for an anvil for a pile driver. A temp. mast acts as the guide for a short jib with a monkey which is raised by a rope winch to exert the ramming blows. A mast (10) is kept upright by a tube (16) and acts as the guide for the jib (11) with a monkey (8,9). The inner tube (1) consists of sections (2,3) which are coupled by a taper thread (4). The leading tube has a ram point. At the rear end, an adapter (6) is screwed on for an anvil (7) to absorb the impacts when the drop weight is released.

Title: Dispensing pump for spray bottle - has upper edge walls of trigger bulb providing valving actions, with release of bulb sucking in liq. from bottle
Inventor: LIBIT SIDNEY M
IPC: B05B11/00
Filed: 1981-06-18
Abstract: The pump is for dispensing liq. as a spray, and the trigger and the flexible pumping chamber (14) are an integral unit. The upper ex edge walls of the trigger bulb (58,56) provide the valving actions which open or close the passage ways to control the direction of fluid flow. On squeezing the trigger bulb, the fluid is exhausted through a gap, and on releasing the trigger it is recharged by liq. being sucked in from the container between the faces (58,59). The trigger may have a back stop (15) which may also act to deform the bulb when it is squeezed.

Title: Electric coffee maker with detachable cold water container - uses cylindrical segment to block water escape from bass when the cold water container is detached
Inventor: MAGG JOHANN
IPC: A47J31/057
Filed: 1981-09-09
Abstract: The device has a detachable cold water container and a rotating valve to block off the water in the base unit when the water container is removed. The cold water container carries the riser pipe for the heated water and the spout which directs hot water into the coffee filter. The container and riser pipe assembly is detachable from the base of the unit. The base contains an electric heating element surrounding a duct through which water passes as the expansion of the heated water forces water up the riser pipe and into the filter. A coffee container rests on the plate forming the top of the base unit and is heated by the water heated by the electric coil. When the water recipient is removed a geared cylindrical segment is rotated to prevent loss of water from the base unit.

Title: Fire extinguisher with contents under pressure - has discharge valve slide with check float and actuated counterweighted hand lever
IPC: A62C13/64
Filed: 1981-09-30
Abstract: The fire-extinguisher uses a slide valve (4) actuated by a hand lever to discharge its contents. The lever has a counter-weight (19) to maintain the contents permanently under pressure. A valve-housing (1) on the extinguisher locates the slide and the compass with the weight. An integral push rod (4c) is used to transmit lever movement to the slide. The pressure inside the extinguisher maintains contact between the rod and the lever and dead slide travel permits comparative pressure verification. The hand lever is depressed to take up the dead movement and the return movement verifies the pressure. A breakable locking pin (15) located by a slot hole (16) may connect the compass arms and limit the dead movement.

Title: Sand mould prepn. - by applying a vacuum for sand compression and penetration by hardening gas
Inventor: UZAKI NAGATO
IPC: B22C9/12
Filed: 1981-11-26
Abstract: A mould is produced by filling the mould box with the pattern by a mixture of sand with a gas hardening binder, covering it by a foil and applying a vacuum to compress the contents. The top is then connected to a hardening gas source and the vacuum is again applied to pass the gas through the mould and complete the sand curing. This simplifies the compression and curing of the sand. The mould need not be designed for a high pressure and the sand consumption is reduced to a minimum.
