Patent DE-2336066-A1 (DE)
Title: Pneumatic positioner - plunger operating within hollow secondary piston with restricted port connections
Inventor: BUESING ALBERT
IPC: F15B15/14
Filed: 1973-07-16
Abstract: The plunger, when performing a stroke, is stopped in its travel before reaching its extreme position. The hollow secondary cylinder travels at the same time faster than the plunger and after reaching its extreme position, the plunger, by following up, compresses the enclosed air volume, which then escapes through restricted openings to the atmosphere. The damping effect occuring at the end of each stroke is achieved by the design of the restricted openings and is further increased by the simultaneous intake of air through the corresponding restricted opening on the opposite side of the plunger.

Patent DE-2422778-A1 (DE)
Title: Electrical heating plate for storage heaters - is fitted with meandering heating wire embedded in ceramic plate with slots
Inventor: KUMMER LUTZ
IPC: H05B3/28
Filed: 1974-05-10
Abstract: Slots are made in the ceramic plate edges facing the butt ends of the meandering heater and these slots facilitate the cracking of the plate in suitable places, e.g. half-way between two resistor ends not connected with each other. They are transversal to the long dimension of the plate edge and their depth is approx. 3 mm. and their cross-section is U-shaped. The plate is liable to crack due to thermal stresses even if precautions against cracking are taken, so possibly causing extra strain on a part of the wire. The arrangement according to this invention prevents damage occurring to the heat conductor.

Title: Reinforced concrete window sills - has firmly connected trough shaped sheet reinforcement on its underside
Inventor: HACK GUENTER
IPC: F24D19/02
Filed: 1974-06-04
Abstract: The sheet reinforcement accommodates tensile stresses while the concrete or stone accommodates compressive stresses. The sills can overhang over long spans and they can be adapted to given window widths. The sheet steel profiled channel expands upwards and forms a slope for good conduction of warm air. The edges of the sheet metal trough can be embedded into concrete for forming smooth surface and a cavity can be left into the lower part of the beam for accommodating supply pipes and ventilating features. This cavity can also be filled partly or completely with foam plastics for ensuring good thermal insulation. The trough shaped sheet steel reinforcement (1) is a profiled section of constant cross section and this is connected firmly with the stone or concrete (2). The sheet steel reinforcement inwards turned edges have holes (6) for improved keying effect.

Title: Photoelectric metal melt level control - used in continuous casting gives minimum disruption by formation and removal of slag
Inventor: LEVI ISRAEL
IPC: G05D9/12
Filed: 1974-08-08
Abstract: The speed of the solid metal for casting and/or the flow of molten metal into the mould are controlled by means of photocells which convert the light emitted from the melt surface into control voltages for electric motors. The light flux from an area of the melt surface which retains its size on a change in melt level is compared photoelectrically with that from an area which varies in size on a change in melt level, and the electric motors controlling the level are regulated by a signal derived from the difference in the light fluxes. The light from the melt surface (24) is pref. directed by inclined diaphragms (26) and converging lenses (28) onto photocells which produce the light flux signals.

Title: Matching characteristic impedance of strip shaped cable - has rectangular openings in potential plane decreasing capacitance increasing inductance
Inventor: BRAECKELMANN WALTER DR ING
IPC: H01P3/00
Filed: 1974-09-16
Abstract: The arrangement is to increase or match the characteristic resistance in strip shaped conductors in multi-layer wiring. The thickness of the insulation layer is small compared to the width of the conducting strip and the conductor is located at a given distance from the potential plane (P).

The width of the openings is larger than the width of the conductor. Similarly the length of the opening is larger than the width of the conductor. The distance between centres of the openings is considerably smaller than the smallest wave to be transmitted.
