Title: Magnetic accounting card with magnetic edge strip - edge strip next to line-determining scanning strip both sides
Inventor: MOOSMUELLER HELMUTH
IPC: G06K19/08
Filed: 1974-12-13
Abstract: The accounting card has most of its surface (2) free for visual records. On the left edge is positioned the line-determining scanning strip (3) and inside and close to it a parallel magnetic strip (4). Similarly on the reverse side of the card a further line-determining scanning strip and a magnetic strip are positioned on the left hand side of the card. By having the pairs of strips located always on the left hand side the possibility is reduced of contaminating the magnetic strip with its neighbour when cards are stacked.

Title: Composite reinforced-concrete load bearing structure elements - comprising thin metal or other membrane with reinforcing meshes forming independent support
Inventor: BASTGEN ALOYS
IPC: E04C5/06
Filed: 1975-01-27
Abstract: The composite elements are for load bearing structures such as slabs, beams, slab-beam ceilings, ribbed ceilings, walls, columns, frameworks, whole structures or building components made of reinforced concrete or other hard-setting materials, serving as scaffolding and formwork during assembly and eventually as reinforcement. The elements are made up from a thin membrane (1) of metal etc. stabilised and reinforced by spot-welded or cemented reinforcing meshes (2) or intersecting rodsan independent support structure, either alone or in conjunction with the inlaid support reinforcement (3), which is made from individual rods or reinforcing meshes. This becomes an integral supporting component of the final load bearing structure, unwanted fissures are prevented, and transport is simplified.

Title: Synthetic fibre convertor bands - which are produced with higher output by dividing up threads before crimping
Inventor: ESSIG KARL-AUGUST DR
IPC: D02G1/12
Filed: 1975-02-04

Title: Continuous chipboard or fibreboard press with endless belt - pressed down by weight of return roll and very large driving drum
IPC: B30B5/06
Filed: 1975-03-18
Abstract: A press for the continuous production of chipboard, fibreboard or other pressed material comprises a fixed pressing table and, above the table, a pressure-applying unit consisting of a plate, a driving drum, a return roll and an endless belt passing around the drum and the roll. The drum is of excessively large dia. compared with the roll and the whole pressure-applying unit is suspended so that it can move vertically in its restraining frame and is sufficiently heavy to apply the pressure by its self-weight.

Patent DE-2543745-A1 (DE)
Title: Engine with external combustion - has complementary heat exchanger to absorb heat from one piston system via changeover valve
Inventor: VOOS UDO
IPC: F02B3/06
Filed: 1975-10-01
Abstract: The engine has two piston systems preferably working in counter stroke from a common crankshaft. A complementary heat exchanger absorbs heat from one piston system via a change over valve, a by pass and a cooler. The size of the heat exchanger is dependent upon the temp. difference between both sides of the heat exchanger. The heater construction depends upon the fuel type and the cooling is achieved by slip stream. The system could also be used with engines working on the Stirling principal and using a Rhomben gear.

Title: Controlling carbonisation time in coke ovens - by regulating the length of the regenerator half cycle times
Inventor: PRIES ERICH DIPL ING
IPC: C10B21/20
Filed: 1976-02-09
Abstract: In a coke oven battery the heating walls are subdivided into rows of heating flues alternating with oven chambers, the contents of which are heated uniformly in respect of height by controlling the combustion in the flues. Using baffles, bricks, sliders etc. which act on the various heating flues of each heating wall. The amt. of heating gas supplied in unit time is adjusted to provide a carbonisation time corresp. to a high prodn rate for the battery. The method of application of the flames in the heating flues as well as the position of the various control element as maintained above are kep unaltered when the carbonisation time is increased, but the lesser heat requirements are taken into account by introducing an interruption into each half cycle of regeneration. System provides a much simpler and more rapid method of altering the carbonisation time while maintaining complete uniformity of heating throughout the oven chamber, than the usual method of altering the rate of feed of heating gas and the position of the control elements for air, combustion gases etc, which can take several weeks.
