Title: Interlocking paving stones drainage - uses pipes as under surface channels with holes adjoining paving cut=outs
Inventor: SEITZ KARL
IPC: A01G31/02
Filed: 1976-12-09
Abstract: The paving is of the type made up from artificial stones (1) laid close together in the form of interlocking blocks with channels running below the surface. The channels are in the form of pipes, with lateral openings adjoining cutouts in the paving, connected to the paving surface. The pipes may be made of plastics. They form a pipe system, with the cutouts at fixed intervals matching the paving pattern, the pipes being pref. plugged together from individual pipe sections. The stones may incorporate an underside lengthways groove (4) engaged by a pipe section, and a transverse groove (9, 10) at one end from surface to lengthways groove. This system provides a number of uninterrupted channels with min. flow resistance, with no risk of water trickling out.

Title: Continuous stationery edge binding system - has adhesive applied through openings for flow over staggered edges of sheets
Inventor: ROST HEINZ
IPC: B42C3/00
Filed: 1977-01-17
Abstract: The method of securing together a set of sheets with adhesive is suitable for continuous stationery. It has the sheets (1, 2, 3) arranged in step formation and the adhesive (7) applied in a continuous or interrupted flow to the staggered edges. This adhesive can be applied through a series of rectangular openings each positioned above a set of edges. The lines of rectangular openings are parallel to the direction of travel (14) of the sheets. The lowermost sheet (3) of a set does not have rectangular openings, but the other sheets have openings. This permits the adhesive to flow down from esp (1) to bottom (3).

Title: Silver halide photographic material - with antistatic coating contg. unsaturated carboxylic acid fluorinated alkyl ester polymer
Inventor: BUTLER LOUIS
IPC: G03C1/76
Filed: 1977-09-01
Abstract: A photosensitive material comprises a support coated on >=1 surface with >=1 Ag halide photographic emulsion layer coated in turn with a top layer comprising an F-contg. (co)polymer. The latter is derived from a fluorinated alkyl (opt. branched) ester of an ethylenically unsatd. carboxylic acid. The fluorinated alkyl group contains no more than one H or Cl for 2C atoms and one O or N for 2C atoms. The polymer may be present on its own or, besides the top layer, it may be incorporated in one or all emulsion layers or in an intermediate layer between the support and the emulsion layer. The polymer prevents the accumulation of static charges when the material is processed, partic. in high speed radiographic appts. Formation of static streaks on films is thus avoided.

Patent DE-2741744-A1 (DE)
Title: Radial press esp. for glued sandwich panels - has feed and discharge conveyors temporarily synchronised with press rotation
Inventor: SIPLANE JOHAN
IPC: B27D3/00
Filed: 1977-09-16
Abstract: A radial press system comprises individual presses all projecting radially from a revolving drum. Each individual press receives in turn a flat article to be pressed, e.g. panels or boards coated with glue to form sandwich structures. The press is supplied with the components of the sandwiches by a feed conveyor and a discharge conveyor. These conveyors are in line with each other and parallel to the axis of rotation of the press and at such a distance from that axis that they are also in line with the individual press which is instantaneously passing between them as the entire radial press rotates. While the individual press rotates between the feed and discharge conveyors, these conveyors pivot through an arc so as to accompany the movement of the press and thus enable the sandwich components to be transferred from the feed conveyor into the individual press and to enable the completed, pressed panel to be discharged from the individual press onto the discharge conveyor.

Title: Electronic dynamic multiplier with switch controlled by timer - receives two inputs enabling three factors to be multiplied
Inventor: REISSLAND MARTIN-ULRICH PROF D
IPC: G06G7/161
Filed: 1977-12-09
Abstract: An electronic dynamic multiplier has a switch operated periodically with a variable ratio between duration of closure and switching cycle duration to switch a first current or voltage parameter. The duration of closure is determined by a time element controlled by a voltage-to-frequency converter driven by the second current or voltage parameter. The switch drives an averaging circuit. It enables accurate multiplication of three factors with low cost. The timing element produces a current or voltage proportional closing duration and may receive a third input parameter.

Title: Homo-kinetic universal joint race hardening - in solid fixture preventing thermally induced radial deformation
Inventor: SCHWENK WOLFGANG
IPC: C21D9/40
Filed: 1978-04-20
Abstract: The outer race of a homokinetic ball-type universal joint has axial running grooves which have to be hardened by brief heating of the inner surface to the hardening temp. and quenching by a liquid coolant. During this operation, a fixture prevents the radial thermal elongation of the race. This achieves a cylindrical or slightly concave shape of the generating lines of the ball running tracks of the outer race.
