Title: Scrubbing brush or broom head of polyurethane foam - increases in density from interior to outer extremity skin
IPC: A46B5/00
Filed: 1979-05-03
Abstract: The material forming the head of a bruch or broom for rough work such as scrubbing, is integral polyurethane foam, the density of which, in the central zone of the head where, the bundles of bristles are fixed, is less than that of the outer zones. In the edge zones the density increases uniformly to a max. at the outer skin. The bundles of bristles are held more securely by the foam of lower density, whilst the outside zones of the head are fully capable of standing up to the heavy loading imposed during the cleaning process. The bundles of bristles with e.g. wire rings, can be assembled into the bores of the head on normal machines without alteration.

Title: Heating coil support for underfloor heating - consists of interlocking plastics panels with projections shaped to guide bends and straight parts
Inventor: WEINMANN HEINZ
IPC: F24D3/14
Filed: 1980-06-27
Abstract: The supporting system for the tubes of a heating coil for an underfloor heating system uses rectangular plates with edges shaped so that they can be interlocked to form a large area corresponding to the size of the room. Each plate carries a pattern of projections (13) which guide the tube (14) so that a coil of a required shape can be supported and guided. This shape includes round portions and straight portions, the latter being parallel or diagonal to the sides of the plate. These projections can be approximately triangular, the base (20) of each triangle being convex with a small point (22) projecting from the centre. The wall of the tube is then gripped between pairs of these convex faces, assisted by the points. The tubes are also guided between the narrow rounded tips (23) at the base of each triangle. The spacing of these projections matches the minimum permissible bend radius for the tube. Another design uses pear shaped projections.

Title: Floating diffusion output stage for CCD - prevents reset noise by additional reset gate
Inventor: MAUTHE MANFRED DIPL ING
IPC: G11C19/28
Filed: 1980-07-29
Abstract: A reset circuit with suppressed reset noise, specially for a floating-diffusion output stage of a charge-coupled device is equipped with an additional gate between drain and source of the reset transistor on the source side next to the reset gate. This additional gate receives a fixed d.c. potential which is lower than the reset timing pulse amplitude; the latter is smaller than the reference potential on the reset transistor. The reference potential is also greater than the surface potential under the reset gate and that under the additional gate. This eliminates the reset noise in spite of any present amplitude fluctuations of the reset timing pulse voltage.
