Title: Cutting machine for synthetic foam blocks - effects four adjustable cuts at right angles without turning the block
Inventor: POETZSCH ROLF
IPC: B26D1/00
Filed: 1975-06-04
Abstract: A cutting machine, esp. for blocks of foam, is arranged with feeders for controlling the motion of the block relatively to the cutting tools. These consists of endless wire saws running on gide rollers along a number of cutting lines; the guide rollers being assembled in frames partly designed to be driven and partly to apply tension to the saw. The frames together with the saws are located in neighbouring horizontal planes and the feeder works vertically, slots in the table allowing the saws to sink below its surface. A large number of the cuts, possible on a long production line, can be executed in a very limited space, without a serious reduction of the efficiency of the machine.

Title: Water blocking fin for prestressed rod in concrete dyke - has disc and coplanar surrounding plate cold welded to intermediate threaded sleeve
Inventor: KETTLING FRITZ
IPC: B23P11/00
Filed: 1975-06-06
Abstract: The construction of concrete dams and dykes involves prestressing rods which are embedded in the concrete. To prevent water seeping along the rods, the rods are fitted with blocking fins.

A plate (4) is mounted over the outside of the sleeve. The hole in the plate has very small tolerance dia. so that there is little clearance between plate and sleeve. Plate and disc are mounted in the same plane. Pressure is applied to both sides of the disc and plate so that the disc expands outward and the plate flows radially inward, cold welding the parts together.

Title: Asbestos cement tubes with reinforced plastics ring - are connected by coupling sleeve unit incorporating rings and seals
Inventor: WEGERT ALBERT
IPC: E03F3/04
Filed: 1975-07-08
Abstract: Asbestos cement tube connected to similar asbestos cement tubes by coupling elements to form a pipeline used for lining of wells. No grooves are cut into the ends of the tubes which could lower the strength of the tube. The connection ring made from glass fibre reinforced plastics accommodates bending and shear forces without imparting excessive loading to the asbestos cement tube. The end region of the tube (10) has on the outside the glass fibre reinforced plastics connecting ring (11) held on the tube by adhesive bonding. The thickness of the ring increases towards the free end of the tube, and the tapered or stepped ring has also a parallel section near the pipe open end. The coupling is connected by a coupling ring held in grooves (15) of the ring on the tube ends and within the enclosing coupling sleeve which bridges the ends of the two tubes. Alternatively one of the rings can be extended to form a socket into which the end ring of the adjacent tube end fits.

Title: Resistance spot welding molybdenum or tungsten - where auxiliary wire located between electrodes prevents material sticking on electrodes
Inventor: TROST FRANZ
IPC: B23K11/18
Filed: 1975-07-16
Abstract: The auxiliary wire is pref. located between or on top of the tow parts being welded together.

Title: Rotary IC engine without valves or reciprocating parts - for gaseous, liquid or solid fuels, using continuous combustion has two meshing rotors
Inventor: HANFELD FRANZHERMANN DIPL ING
IPC: F01C1/12
Filed: 1975-09-02
Abstract: The centrifugal IC engine comprises two or more rotors (2) with meshing blades, (1) in a casing. There is a combustion chamber (3) and the whole is so configured that where the meshing rotors provide the combustion chamber sealing (A) one blade only is under pressure, where as two blades are exposed to this pressure where they seal against the casing (B). Products of combustion are ejected late in the cycle (D). Fresh combustion air, which may be supplied under pressure, enters the system (E) after discharge of the exhaust gasses; it is compressed further before entering the combustion chamber. The fuel fed into the combustion chamber may be gaseous, liquid or, in large units, even solid. Sealing between rotors (2) is improved by providing suitably shaped grooves which the blades engage; blade edges used for sealing may also be serrated.

Title: Radiation detector output preamplifier overvoltage protection - has output of signal generator, responsive to arrester diode current, coupled to amplifier input for flip=flop control
Inventor: LANG BERNHARD DIPL ING
IPC: H02H3/20
Filed: 1976-09-22
Abstract: The radiation detector, such as a Geiger counter, has a detector cell (Z) energised by high direct voltage (UH).
