Title: Magnetic tape transport appts. - has tape supply and take=up reels biased towards capstan by magnetic brakes on reel shafts
Inventor: GEHRUNG MANFRED ING GRAD
IPC: G11B15/295
Filed: 1978-01-18
Abstract: The magnetic tape transport includes supply and take-up reels (23, 24) whch are ruged towards a capstan (21).

Title: Matrix printing process forming dot pattern - which represents characters in groups on parallel lines inclined to gaps and may write two dots simultaneously
Inventor: LOTZE WOLFGANG ING GRAD
IPC: B41J2/505
Filed: 1978-08-08
Abstract: The process reproduces characters in a dot pattern using a matrix-type printing mechanism with comb having m recording electrodes. The dots representing a character are arranged in groups in a pattern with m-2 lines and n gaps, all those in a group being on parallel lines inclined to the gaps. These lines are spaced apart inthe writing direction at intervals equal to half the distance between two dots, and in the gap direction equal to this distance. Each group is then increased to a total of two dots by addition fo the latter as necessary. On printing the dots for the characters are written in the first (m-2) lines, and the additional dots in the last two. Sufficient gaps without dots are formed between two characters for none of the parallel lines to run through two characters.

Title: Hot water circulating system non return valve - has valve member allowing minimum flow through by pass line when closed
Inventor: JUX HANS
IPC: F24D3/02
Filed: 1979-08-04
Abstract: The non return valve (6) for the flow of hot water circulated by a pump in a hot water supply system also includes a connection (10) for a by pass line. The valve which is incorporated in the return line to the boiler has in-line connections (8,9) with a cylindrical valve member (14) with a flanged end, moved downwards by the water flow, and a return spring (15) above it. When open, the sloping underside of the flange closes the branch outlet.
