Title: Telecommunication cable attenuation compensator - has PIN diodes controlled by temperature sensitive amplifier
Inventor: LECHENAUD JACQUES
IPC: H04B3/14
Filed: 1975-06-24
Abstract: A gain temperature compensation unit is used to compensate for attenuation over a wide frequency band of teledistribution cables. It is an open loop device and is used for 40 to 860 megahertz. The unit, has PIN diodes (55, 56) whose high frequency resistance varies with the direct current (ic) flowing through the diodes. The current (ic) is supplied by an amplifier whose gain varies according to the temperature of the cable. The HF signal (HF) which is being compensated flows through capacitors (51, 52). Some of the signal (HF) is shunted through the diodes (55, 56) and capacitors (59, 60). The amount of shunted signal depend on the resistance of the diodes (55, 56) and therefore of the temperature of the cable.

Title: Lid for container for paint spraying gun - has air vent hole in plug made of PTFE to reduce paint flow through hole when gun is tilted
IPC: B05B7/24
Filed: 1976-04-21
Abstract: The paint spraying gun (1) is provided with a paint container (3) supported from the lid (2). The lid (2) is provided with a PTFE plug (7) with a small hole of 0.3 to 0.5 mm dia. This hole allows air to flow into the container as the paint is being sprayed. When the gun (1) is pointed downwards or upwards to spray horizontal surfaces there is a tendency for the paint to flow out through the vent hole. By using PTFE the paint does not stick to the surfae of the hole and so the tendency to flow out is much reduced. The plug outlet is surrounded by a circular ridge to catch any drops which nevertheless might flow through the plug.

Title: Automatic safety belt opening device - has levers with springs and pin actuated by belt tractive force
IPC: B60R22/32
Filed: 1976-09-27
Abstract: The automatic opening device is particularly for the attachment of a motor vehicle safety belt. It incorporates a mechanical device operating it as soon as the tractive force exerted on the belt has decreased, and comprises a set of levers and springs and a support pin working simultaneously under a tractive force imposed by the belt as the result of a shock. When at rest, the device can be opened manually.

Title: Grid for preventing errors in charging nuclear reactor - incorporates central opening for inserting fuel elements singly, and stops, preventing insertion without control elements
Inventor: BARABACH BORIS
IPC: G21C5/06
Filed: 1976-10-28
Abstract: An appts. for preventing errors in charging a nuclear reactor incorporates an upper grid above the core and parallel to the lower supporting grid. The upper grid has lateral openings for introducing control rods in line with their positions in the core, and a central opening for inserting the fuel rods, one by one. Passage through this central opening is prevented by bolts which open under the effect of cams carried on the control rods, so that a fuel rod cannot be charged until all the control rods have been inserted in the core. The fuel rod is charged through the central opening and then moved transversely into its place between two control rods. The appts. is partic. applicable in the case of an experimental reactor, in which the core is submerged under a quantity of water. Devices based on preventing incorrect engagement of the fuel element in its housing in the support grid or giving the heads of the elements different shapes so that a grab cannot pick up the wrong one, have been shown to lead to error. The invention avoids these disadvantages.
