Patent DE-2361207-A1 (DE)
Title: Telecommunication cable with plastic insulated conductors - has sealing filler against longitudinal water penetration
Inventor: FALKE HENNING DR RER NAT
IPC: H01B13/32
Filed: 1973-12-06
Abstract: The telecommunication cable with plastic insulated conductors has a filler for longitudinal sealing of the cable against water penetration. The filler may be non-polar, foamed-up and reticulate bonded by a high frequency process such as by passage through a UHF cavity resonator. The filler can be applied to the individual conductor before twisting or in the case of a cable with multiple twisting stages can be applied before the consecutive twisting process on to the twisted element. Due to the reticulate bonding favourable elastic properties are obtained and by the foaming-up of the filler the dielectric constant is reduced which results in an improvement of the overall transmission properties of the cable.

Title: Typewriter half-revolution coupling - wherein successive half-revolutions are initiated by alternate digits of binary signal
Inventor: HANENKAMP HORST
IPC: B41J29/38
Filed: 1973-12-17
Abstract: The coupling is especially for additive positioning of the type carrier in typewriters. The driven member of the coupling is a disc capable of being held against rotation by engagement of a pivotal pawl with one of two diametrically opposite steps in the disc periphery. The steps are of the same height but of different radial positions so that the pawl has different angular positions when resting at the foot of the respective steps. A pawl release rod is movable longitudinally to release the pawl and is settable transversely by an electro-magnet into two positions in which abutments on the pawl match the respective pawl positions.

Title: Acoustically-triggered switching circuit - has microphone operating flip-flop with delay circuit containing photocell to maintain stair lights
Inventor: KAUSCH UWE
IPC: H03K17/94
Filed: 1974-02-26

Title: Sea-wave simulator for use in aquarium - consists of electronic time-switch which is operated by solenoid valve, introducing air from both sides
Inventor: HOENICKE ERNST
IPC: A01K63/04
Filed: 1974-12-30
Abstract: The solenoid valve (4) uses an electrical lead (10) to switch off the electronic time-switch (5). This causes the air coming from the air-source (6) through the air-inflow pipe (7) to arrive through the solenoid valve (4). The air passes through the air-pipe (9) to the first discharge point (3) and thereby produces waves in the aquarium creating the right conditions for the living creatures in it. The electronic switch (5) then activates the solenoid valve (4) and the magnet in it is attracted. The air is drawn to a different point and flows through air-pipe (8) to the discharge point (2) and produces the same wave effect in the opposite direction. The electronic time-switch (5), and the solenoid valve (4) are housed in the same casing.

Title: Corrugated paperboard mfr. - using a chemical gelatinisation temperature depressant on the flute tips of the corrugated medium
Inventor: JOHNSON PAUL ALLEN
IPC: B31F1/28
Filed: 1975-01-08
Abstract: Double-faced corrugated paperboard is produced by coating the exposed flute tips of a corrugated medium faced with a single liner with a gel point depressant, and subsequently applying an adhesive layer over the coating using a roller with the layer of adhesive on the roller bing thicker than the coating of gel point depressant to cause splitting of the adhesive layer on the roller into a lyer on the flute tips and layer on the roller, isolating the gel point depressant from the adhesive roller. An additional board layer is applied to the coated flute tips prior to the gel coat depressant causing gelatinisation of the outer exposed surface of the adhesive.

Title: Roller for swimming pool plastic heat retaining cover - has insert tube connecting split tubular rolls
Inventor: BOJAK KURT DIPL ING
IPC: F24J2/04
Filed: 1975-06-18
Abstract: The open air swimming-pool cover comprises material floating on the water, and is designed to allow max. penetration of solar radiation while checking return radiation from the heated-water. The material used is plastic foil sheeting. An insertion tube (E) is used for the connection of two or more roll-up devices.
