Title: Press for two or more workpieces - has controlled transfer of fluid between two sets of press pistons
Inventor: GREBE WOLFGANG
IPC: B30B11/02
Filed: 1975-12-20
Abstract: The hydraulic press has a single ram, and workpieces (16, 17) are placed between a die and matrix on two hydraulic pistons (9, 10).

Title: Ceramic injection moulding machine - keeps mould halves slightly apart during injection before moving together
Inventor: ATTIG HANS
IPC: B28B1/24
Filed: 1975-12-27
Abstract: Injection-moulding machine produces ceramic mouldings in the leather-hard state, i.e. they can be handled without risk of damage during baking or other subsequent operations, the ceramic mass being thrust under pressure into a split mould. During injection of a quantity of material corresponding to the dimensions of the moulding the halves (12,31) of the mould are held slightly apart, so that only partial filling of the space between them takes place. The mould tool on the injection side (10) is then shut off, and the halves moved together into the final position. In this position they form with a section of the mould ready for use (16) a space corresponding to the shape of the finished article.

Title: Non:return valve for water tap supply chamber - has flexible shock wave absorber disc with screw plug tubular insert
Inventor: SCHMIDT HEINZ
IPC: E03C1/042
Filed: 1976-02-11
Abstract: The insert (8) fits into the supply chambers (4) of a hot and cold water mixing tap and includes a non return valve (14-16). The tubular insert (8) is attached to a screw plug (9) which forms one end wall of the supply chamber (4), thus it is easy to install. A flexible disc (21) is located between the internal shoulder of the screw plug (9) and the axial end face of the insert (8).

Title: Arc welding torch aligned by optical scanning of seam - using photodiode array in electronic circuit contg. process control computer
Inventor: KING FRANZ-JOSEF DIPL ING
IPC: B23K9/12
Filed: 1976-02-16
Abstract: A torch head is aligned during electric arc welding by contactless scanning of the weld gap. The image of the gap just in front of the head is resolved into individual spots of intensity (Ia), which are compared with a threshold value (It) to obtain signals providing a rectangular image. The position and width of the latter provide signals employed in a known way to control welding parameters. The pref. appts. includes a driven transverse slide separate from that on which the head is located and carrying a scanner consisting of a magnifying lens followed by a row or matrix of photodiodes providing a digital image in an electronic circuit converting the data into signals for aligning the head; controlling root penetration; and for feeding filler rod etc. Either stray light from the arc, or a separate lamp and optical fibres, can illuminate the scanned zone. A pref. alternative appts. uses fluidics to scan the gap. Used e.g. in welding long plates using an I-joint with gap below 1 mm, where the invention maintains torch head alignment.

Title: Self-locking cap nut made by welding - with formation of corner butt weld between cap and nut
Inventor: ERDMANN HEINZ
IPC: B21D53/24
Filed: 1976-02-25
Abstract: Mfr. of a self-locking cap nut comprises electrically welding a cap, which is drawn from sheet metal and provided with a bevelled outer edge, and which is pressed against a metal nut to form a corner butt weld on the inside. The welding process is divided into pre-pressing, welding and holding stages. The metal nut is subjected to cold deformation in the region of its thread to form an annular attachment which is compressed concentrically to provide the required locking force. Then the cap, which engages over the conical attachment with a slight clearance is uniformly welded to the nut to form an intermediate corner butt weld.

Title: Heavy-duty, flexible, multi-conductor cable - for supplying coal cutting machines with power
Inventor: VALDORF FRITZ ING GRAD
IPC: H01B7/04
Filed: 1976-04-28
Abstract: Power cable has a core of three corded conductors, a protective conductor and a supervisory (control) conductor. The core is surrounded by an inner and an outer mantle, and a braiding of high tensile textile, plastics or steel wire filaments is embedded between the two mantles. Each conductor has a conductive extrusion-coating. In each of the spaces between the three corded conductors, there is one-third of protective conductor and one-third of supervisory conductor, these conductors, forming, in each space, a common flexible conductor. The protective conductor is in electrical contact with the outer conductive coatings of the conductors all of which are dusted with graphite powder. Each conductor consists of blank, non-galvanised, Cu-wires and is surrounded by a plastics film, and an insulation of a peroxide-crosslinked ethylene-propylene copolymer or an EPDM. The cable construction combines flexibility and tensile strength with electrical efficiency even when subjected to heavy starting currents.

Title: Axially joined steel support leg - uses cylindrical and profiled tube to prevent buckling of long sections
Inventor: KREISKORTE HEINZ DR ING
IPC: E02B17/02
Filed: 1976-06-16
Abstract: A steel tube which is used to support offshore installations is constructed by welding together a number of cylindrical tube sections. In order to obtain the required strength against buckling of the very long tubes, profiled tube sections are also included in the construction. An axial cross section of the profiled tubes shows that some have a localized increase in wall thickness. Others have an internal radial rim or a complete axial wall. Where two tube sections are in contact to produce a welding joint, the wall thickness is equal.
