Title: Printed circuit board chassis - allows irregular spacing by mounting each board in standard frame which is clamped into chassis slots where required
Inventor: FELSECKER FERDINAND ING
IPC: H05K7/14
Filed: 1976-05-06
Abstract: The chassis unit, which holds printed circuit boards, allows boards of different component depths to be accommodated by allowing the boards to be mounted in the chassis at different pitches or spacings as required. The main chassis element consists of a box at the top and bottom rear corners of which are mounted specialized slotted mouldings held in place by the back plate. Printed circuits are mounted in frames with screw fittings which allow these to be clamped into the moulding slots at any points required thus allowing boards to be mounted in the chassis each with the spacing from the next board which it needs.

Title: Sorting device for granular materials - has high-speed separation of fine and coarse particles through fluidised vortex
Inventor: YOSHIMORI NOBUO
IPC: B07B7/083
Filed: 1976-08-12
Abstract: The sorting device for granular materials comprises a cylindrical housing (1), an inlet (2) for feeding fluid into the base of the housing which produces an upwardly aligned vortex current towards an outlet opening (3) at the top of the housing (1) and a supply mechanism (19) which feeds the particulate material into the upwardly aligned current.

A further rotary slide member (8) is mounted above the inlet (2) and has several radial nozzles (6) which send jets of fluid towards the inner wall of the housing. Several guide plates (25, 26) are mounted near the inlet (2) to provide an even guide for the coarse particles as they fall down along the inner wall of the housing so that they are not taken up by the vortex. These coarse particles are drawn off through an outlet (4) at the bottom of the housing (1).

Title: Rotary and impact borehole drill operating system - varies frequency and amplitude to reduce power loss and noise (BE 20.3.78)
Inventor: KLUGE GUENTHER DIPL ING DR
IPC: B25D9/12
Filed: 1976-09-18
Abstract: The rotary and impact drill for making boreholes in mining and tunnelling operations, uses a pressure medium to obtain impacts at a given frequency and amplitude, which can be applied so as to change the direction of rotation between impacts. By simultaneously reducing the amplitude and the frequency to about 4000 Herz, the complete energy is reduced. This action is taken to reduce the energy lost by turbulence and vibration, and to reduce noise. For combined rotation and impact operation the reversal speed of the drilling rod is increased. The force exerted on the drilling rod is also decreased.

Title: Fuel element transportation container with two=part closure - comprising inner shielding plug and outer lid with fixing bolts
Inventor: KRAINER FRANZ
IPC: G21F5/12
Filed: 1977-08-26
Abstract: A fuel element transportation container intended for the shielded transportation of radioactive substances, e.g. fuel elements, has a feed opening closed by a plug-type lid fitting into the mouth of the container. The lid is composed of two separate parts. The inner part constitutes a simple shielding plug, while the outer part is equipped with the fixing devices. Pref., the inner, shielding plug rests on a sholder of the container mouth. The outer component of the lid pref. has a series of bolts, all operated by a common actuating device, to lock it in position. Although the two separate lids have to be separately handled, the overrall operations are simplified particularly in regard to decontamination. The outer lid can be removed in a clean area, before the container is placed in a contaminated area, e.g. is submerged in a cooling pond. Thus the outer lid with its complicated equipment does not require decontamination. The inner, shielding plug can be simply decontaminated on account of its simple form.
