Title: Nuclear fuel rod spacer grating with resilient support leaves - separate from but permanently connected to side wall of grating aperture
Inventor: ROHR FRANZ
IPC: G21C3/356
Filed: 1978-05-31
Abstract: A spacer for nuclear reactor fuel elements comprises a grating composed of on-edge metal strips, in which the fuel rods are located in the apertures of the mesh by a rigid knob or projection on one side of a mesh aperture and a spring element on the opposite side. The springs are permanently connected to the strip of metal forming the side wall of the mesh aperture and are free to move axially at one end, whereas they are constrained in the radial direction of the rod and in the transverse direction. Used in particular for water-cooled reactors. By comparison with previous arrangements, the separate resilient metal strip provides a greater flexible length and consequently a large elastic movement. It is also possible to vary the spring characteristic within much wider degrees of freedom by varying the length, thickness and material of the resilient strip.

Title: Automatic pressure regulating circuit for endurance testing - esp. of synthetic tube sections with identification of faulty test pieces
Inventor: SOMMER FRIEDRICH
IPC: G01N3/00
Filed: 1978-08-21
Abstract: The previously adjusted pressure applied for the endurance testing of sample pieces, such as sections of synthetic tubing, is monitored by >=1 pressure gauge, having upper and lower limit contacts, and forming part of a pressure control system. These determine the necessary increase in pressure over and above the adjusted pressure. Over the same period, the number of control impulses put out from a central unit for maintenance of the adjusted pressure, are counted. Dependent upon the detection of a definite number of control impulses, e.g. 30% more than the average in each period of time, an operation for the identification of a faulty test piece is initiated. The individual valves feeding the separate test pieces are shut and opened to test each piece in isolation. After identification and registration of the faulty piece(s) testing in parallel is continued, without the faulty piece(s) for a period dependent upon the time which has already elapsed and the number of test pieces which have been excluded. The central control unit contains a microcomputer which receives the signals from a converter and calculates the new testing period.

Patent DE-3012788-A1 (DE)
Title: Hydraulic filter with back flushing - has slotted tube filter elements with valve system to reverse flow
Inventor: KASTL WERNER
IPC: B01D29/66
Filed: 1980-04-02
Abstract: A hydraulic filter with back-flushing comprises filter elements each composed of one or more slotted tubes (31). In filtering operation, a shut-off valve connected to the pressure source allows the liquid to enter the bottom (17a) of the filter element, pass up outside the slotted tube (31), through the slots to the interior, and so out at the top (4). In back-flushing of the filter, the outlet valve from the top of the filter element to the consuming unit is closed but a further valve connected to the top (4) allows back-flushing liquid to flow in from a pressurised source. This passes down inside the tube (31), back-flushes the slots and passes out at the bottom inlet (17a) of the filter element, here it is discharged through a valve leading to atmosphere, which in normal operation would be closed. Useful for low-pressure hydraulic filters designed for back flushing. The arrangement is much simpler than that of conventional filter candles mounted on a disc and each back-flushed in turn.
