Title: Fabric tubing - continuous production with inner lining
IPC: B29D23/00
Filed: 1971-04-29
Abstract: The inner lining is a rubber or plastic film tubing, coated with adhesive. It is fed into the fabric tubing while the latter is being continuously woven, and the double tubing, by means of a suitable internal pressure medium, is inflated against a heating surface to set the adhesive. The composite is finally reeled up at a winding station in which the pressure source is located. Two pairs of rollers are used in the process; the second pair permits the internal pressure to pass from the reeling-up point to the inflation chamber, which is sealed off by the tight setting of the first pair.

Title: Insulation resistance testing device - tests pickups, esp. thermocouples, whose leads are insulated and surrounded by conducting material
Inventor: GERHARD DIPL-ING NIX HEINZ
IPC: G01R27/18
Filed: 1973-08-07
Abstract: Leads of several thermocouples are connected through decoupling diodes to the positive terminal of a voltage source, whose other terminal is connected to the conducting material; a signalling device delivers a fault signal when voltage drop across a resistor between the voltage source and the thermocouples exceeds a specified value; 5 to 60 thermocouples embedded in a ceramic insulator are connected through the above resistor to the voltage source. Instead of the cell or battery voltage source is possible to use the mains supply and measure the voltage produced across the thermocouples.

Title: Zinc pressure-die castings - immersed in bath of molten copper to form surface layer of brass
Inventor: STRAKATA JOSEF
IPC: C23C2/04
Filed: 1973-10-01
Abstract: Pressure die castings, esp. made of zinc with an alloyed surface, have the zinc part, after being made on a pressure die casting machine or on an injection moulding machine, immersed in a copper bath for a precise period of time, established by the use of test-pieces, so that it receives an alloy coating on its surface; the part is then removed from the copper bath and allowed to cool slowly in air; by this means, pressure die casting can be indirectly used to produce parts similar to brass. The coated zinc die casting is pref. provided by this technique with an attractive surface without the use of electroplating and the strength of the part is increased, the weakest sections pref. acquiring the most copper whereas strong or thick sections, e.g. a hexagonal section, retain the strong zinc core. The resulting parts retain their dimensions and do not require surface fettling or a large amt. of subsequent dressing or polishing and can be produced with the thin walls, i.e. pressure die casting can be used to make a part with the appearance of brass.
Patent DE-2360154-A1 (DE)
Title: Valve mechanism for mixing multicomponent plastics - has hydraulic balancing between valves for different components ensuring equal pressure in all components
Inventor: LUPERT GEB RUCK ROSEMARIE
IPC: B29B7/74
Filed: 1973-12-03
Abstract: A valve mechanism for the supply of >=2 components to a plastics mixing head is used in conjunction with a mixing vessel supplied by feed and return lines for each separate component circuit. Each supply line discharges into the mixing head through an outlet valve, and when this valve is closed, recycles back to the storage vessel for that component through a return valve. The discharge valve and return valve for each component are opened and closed alternately by a common hydraulic mechanism so that when one is opened the other is closed. All the identical valve units for the various components are hydraulically coupled such that corresp. chambers of all the hydraulic mechanisms are communicating with one another while the other chambers also communicate with one another, so that hydraulic pressure balancing between all the hydraulic circuits is achieved.

Title: Continuous process printing - where print is transferred by local heating of recirculating band pref. of stainless steel
Inventor: ANGELE FRANZ
IPC: D06P5/24

The pressure is effected by a recirculating felt blanket. After passing a part of the drum periphery the web is wound into a roll while the band passes through a cleaning zone back to the printing zone. Extensive details of the printing ink are given but not claimed.

IPC: A47B96/14
Filed: 1974-01-29
Abstract: The room divider comprises upright bars and wall panels detachably connected together by joints, the individual parts being shaped so that after they are fitted together they form a strip in the manner of a spring which engages in the peripheral groove of the associated wall panel. The strips can be designed to run in different directions, preferably at right angles to each other. Square tubes have projections along a longitudinal face whilst the joints have a polygonal preferably hexagonal core with arms on its faces which engage in the cavities of the hollow bars. A flat or three-dimensional room divider can be built up without any extra fastening means and can subsequently be dismantled with ease without causing any damage to the parts used.

Title: Dynamo armature with two sub-windings per whole winding - has whole winding served by one commutator segment
Inventor: PORTER JOHN H
IPC: H02K23/26
Filed: 1974-02-15
Abstract: The armature, ofr a dynamo, has an iron core with 2N slots and a commutator with N segments for the core's N whole windings. Each whole winding consists of two sub-windings located in different slots. Compared to other armatures the number of commutator segments is reduced by half. The commutator is smaller for a given number of slots, and the number of slots between teeth is increased compared to the number of whole windings so that the armature has greater cooling. The number of segments is at least equal to 11. The armature can be manufactured cheaply.

Title: Long distance wideband transmission of optical signals - using multiple mode fibre divided in at least two parts
Inventor: AURACHER FRANZ DIPL ING
IPC: H04B10/2507
Filed: 1974-07-10
Abstract: A mode convertor is inserted between every pair of parts, converting high modes into low modes, and vice-versa. The mode convertor is a bunch of glass fibres, whose input and receiving signals from the first part is concentric with the first part. Outer fibres of this bunch receive the high modes, and the inner fibres the low modes. fibres in the bunch are so arranged, that at the bunch output and fibres which were at the input end on the outside are now on the inside, and vice-versa. Thus bunch of glass fibres is divided in several parts, and fibres in only one bunch are arranged as above.
