Title: Nuclear reactor safety damping system
IPC: G21C7/22
Filed: 1969-10-07
Abstract: A reactor safety system in which a vertical tube inside the reactor is connected to a similar tube outside the reactor, and the U tube assembly formed contains a liquid which acts as a damper on the reactivity. In the position of equal pressure in each branch, the liquid closes down the reactor. The application of pressure to the top of the branch inside the reactor forces the fluid out and allows the reactivity to reach working levels. A rinsing system is provided to remove all the drops of liquid from the inner tube to avoid reductions in reactivity or corrosion of the tube.

Title: Short duration interruption simulator - provides programmable A.C. voltage supply interruptions, suitable for computer testing
IPC: G01R31/42
Filed: 1973-05-16
Abstract: Random short duration a.c. voltage supply interruption simulator has a control unit and a rectangular signal generator (1), in phase with the voltage supply source, connected to a phase unit (3) which triggers, at the next passage through zero by decreasing values of source supply voltage, a monostable circuit (4) whose period is adjustable, the impulse from the monostable circuit being fed to a electronically controlled static contactor (7), isolated from the supply source.

Title: Automatic folding machine for pancakes etc. - lifts flat pancake from conveyor belt and lets it fall back folded
IPC: A21C15/02
Filed: 1975-03-06
Abstract: A machine for folding pancakes or similar flexible sheets is claimed. Cooked pancakes are conveyed, flat, on a horizontal conveyor belt to pass in turn between a vacuum pickup or suction cup which rises and falls first to lift the pancake at a fold line, e.g., at its median axis or dia., from which the pancake hangs down on both sides with its lowest points clear of the belt; then to lower the pancake with the lowest points advancing first and the fold line at the back. The vacuum pickup is pref. of elongated form to extend right across the dia. or median axis of the pancake and the pickup cycle is initiated automatically by a signal from a detector in the path of conveyed pancakes. An alternating pancake folder grips and lifts the leading edge of a conveyed pancake, and drops the leading edge as the trailing edge is conveyed beneath it. The machine is useful partic. for folding pancakes and the like and having completely automatic operation it offers industrial scale output.

Title: Continuous sintering of ores - with protective layer interposed between sinter layer and igniting g ff flame
IPC: C22B1/20
Filed: 1975-03-14
Abstract: The sintering of ores by a continuous process is improved by pouring onto the material, between the end of the forming zone and the beginning of the ignition zone, a layer of protective solid particles. These particles prevent direct contact between the mixt. and the flame without preventing the transfer of heat to the mixt. and its ignition. Cooling of the surface which slows up the sintering process is avoided and at the same time complete ignition of the surface is ensured.

Title: Regulating working press. of a drill - compensating for the effects of swell during drilling operations at sea
IPC: E21B19/09
Filed: 1975-03-24
Abstract: An appts. for regulating the working press. of a drill and compensating for the effect of swell during drilling operations at sea incorporates means of displacing one of the pulleys over which the cable carrying the drill passes, and thus increasing or decreasing the effective length of cable between its winch and the drill. The means consists of a piston fixed to the pulley and sliding in a cylinder connected to a source of fluid under press. and means of varying the press. in the cylinder. The cylinder may be mounted at the top of the drill structure or on the platform. The invention avoids the inconvenience of the drilling operations being stopped during the increasing or reducing of the weights on the drill, as in existing practice and eliminates the effects of the movement of the platform caused by the action of waves, tides and currents.
