Title: Transfer copying onto a copying paper - having on one face coating capable of receiving the transfer pigment and on its reverse face a coating which is insensitive to the pigment
Inventor: RITZERFELD GERHARD
IPC: B41M5/025
Filed: 1973-07-05
Abstract: A copying sheet has on one face a coating contg. a magnesium-aluminium silicate (e.g. attpulgite, bentonite) and a transfer sheet carrying an image formed by a pigment paste including a leuco-auramine and an alcohol is pressed against thio surface whereby the image is transferred to the copy sheet. The reverse face of the copy sheet is coated with a material which does not react chemically with leucoauramine, e.g. a slightly alkaline dispersion of BaSO4 or ZnO in a synthetic resin (e.g. amido, polyvinyl chloride (polyvinyl acetate copolymer) or carboxymethyl cellulose. The reverse face may be coloured to ensure that the paper is fed into a copying machine the correct way round. Accidental marking of the reverse face of the copy sheet is prevented, since any stray pigment cannot adhere to the coating on the reverse face.

Between any two part discs there project into these slots stationary and electrically active feeler elements which support in one part h.f. electrical elements and in the other part opposing elements coupled to them on high frequency. Depending on their shielding which varies according to the movement of the counting gear, these coupled elements can be read remotely via rectifier diodes and stand for the digits 0 to 9. These digits are also printed or stamped visually legibly on the cylindrical periphery of the relevant indicator wheel, although they are broken up vertically by the three annular slots.

Title: Terminal wire for soldering to cct. board - has U-bends forming spring clamp to grip board edge before soldering
Inventor: HOEH DIETRICH DIPL ING
IPC: H01R12/57
Filed: 1974-07-23
Abstract: The terminal lead wire for soldering to flat circuit boards is shaped to grip over the edge of the circuit board befor soldering to the board contact pad. The end of the wire loops back on itself in one plane and loops back on itself again, but this time in a plane at right angles to the first one. This results in two U-shaped bends with the free arm of the last U-bend folded out of that U-bend plane so that its end lies opposite the curve in the first U-bend. The free arm thereby acts as a clamp and passes underneath the circuit board, whilst the first U-bend lies flat on top of the circuit board contact surface for soldering.

Title: Aerodynamically pre-shaped sail - giving increased efficiency, longer life and lower stresses, allowing top weight savings
Inventor: FELTZ KLAUS
IPC: B63H9/06
Filed: 1975-01-15
Abstract: For any given shape of sail the line- or lines, according to the maximum curvature under aerodynamic loading (51, 52), are calculated, based on the characteristics of the material to be used. Strips of material (55, 56) are then cut and sewn together in such a way that in the completed sail the woof lines of the material are congruent with, and the longitudinal seams are perpendicular to, the lines of maximum curvature. The resultant shape is such that the aerodynamic and mechanical loads are balanced, and distorting loads on the threads are minimised. The remaining problem of random deformation can be minimised by the choice of material.

Title: Spaced panel concreting formwork - uses asbestos cement panels with spacers between them held in by adhesive
IPC: E04B2/86
Filed: 1975-08-06
Abstract: The formwork layout, for concreting work, comprises two panels or slabs, joined to each other by spacer retainers. The two panels are made of asbestos cement, and the spacers are cemented between them. Small plates or breaks may be sited behind the points of adhesion. In preparation, an asbestos cement panel can be given predetermined quantities of adhesive at prescribed points. The spacers are then applied to these points, and themselves coated with adhesive at the other ends. The second panel is then fitted against these ends. Concrete reinforcing units may be inlaid between the panels before they are transported to the building site. The panels are light in weight, and easily manipulated, and the work involved, both at the place of prefabrication and on site, is reduced and simplified.
