Inventor: PABRIG MAX
IPC: H01R24/58
Filed: 1977-09-27
Abstract: This safety connecting device comprises two mutually complementary parts which can be coupled by being pushed into one another axially, a first part being constructed as a plug (1, 1') and a second part as a socket (11) for accommodating the plug. The plug (1, 1') carries a ring (3, 4) for each individual conductor (5, 6), which ring is fitted on an extension (1') of an insulating handle (1) and consists of conductive material, the socket (11) having a depression (12) into which the plug (1, 1') can be inserted axially. A contact (13, 23) for every other conductor projects in the depression at such a point to in each case press in a sprung manner onto a ring (3, 4) of the plug when the plug is completely inserted into the depression (12) in the socket, the earth conductor (8) being connected via axial contacts (7, 22). This safety connecting device prevents live contact parts (3, 4) being exposed when the plug (1, 1') is only partially withdrawn from the socket (11). A possible accident risk is thus prevented. <IMAGE>

Title: Polyurethane foam component mining head - with relatively large outlet from mixing chamber for slower egress speed
Inventor: FINK LOTHAR DIPL ING
IPC: B29B7/76
Filed: 1978-05-29
Abstract: A mixing head for mixing two or more components includes nozzles which inject the components into a mixing chamber. The outlet of the mixing chamber through which the mixture leaves has a larger cross-sectional area than the mixing chamber itself. A cleaning ram can be moved axially in the bore through the mixing chamber up to the end of the discharge section when two valve plungers have been axially retracted. The components are injected in the mixing chamber from two axial bores through two radial nozzles. This combines a good mixing efficiency with an acceptable exist speed which allows the emerging mixture to be poured in moulds. A self-cleaning effect can be retained by simple means.

Title: Mfg. thin metallic structures esp. cadmium chopper discs - by plating over intermediate layer overlapping photolacquer edges
Inventor: HENNIG HELMUT
IPC: C25D1/08
Filed: 1978-06-09
Abstract: Thin metallic (cadmium) structures such as the chopper discs for corpuscular radiation appliances are mfd. by depositing on a substrate an intermediate metallic layer on areas, which are free from photolacquer, in a less aggressive plating bath in such a way that it overlaps the edges of the photolacquer layer. The chopper disc metal layer is then deposited over the intermediate layer in an aggressive plating bath. This creates a reliable method of eliminating the detachment of the edges of the photosensitive layer from the substrate in the extremely aggressive alkaline cadmium bath.

Title: Steam generator for esp. pressurised heavy water reactor - has flattened end dome to reduce heavy water inventory
Inventor: STERK ZVONIMIR DIPL ING
IPC: F22B37/22
Filed: 1978-10-16
Abstract: A steam generator with inverted U-tubes is intended for a pressurised water reactor. The inlet and outlet headers for the prim. cooling water are located in the space between the tubes plate and (bottom) dome of the steam generator shell. An intermediate partition separates these two headers. The vol. occupied by these headers is >=25% (pref. >30%) less than the vol. contained in an imaginary hemisphere having the tube plate as its base. Used esp. for a pressurised water reactor operated with heavy water in the prim. circuit. Due to the expense of heavy water, the redn. in vol. obtd. by adopting a flattened bottom dome to the steam generator shell leads to a saving in the cost of the heavy water inventory which more than compensates the additional expenses of a shell which is not hemispherical and thus optimum from the stress aspect.
