Title: Regeneratable thin layer condenser - made using lacquers which do not dissolve preceding lacquer layers
Inventor: KAMMERMAIER JOHANN DR
IPC: H01G4/015
Filed: 1973-01-26
Abstract: A regeneratable thin-layer condenser comprises dielectric layers and >=2 coatings of opposite polarity. Between and 2 coatings of opposite polarity there are >=2 layers of lacquer, of which >=1 is of a material which promotes regeneration, and >=1 layer, not necessarily the same, is soluble in a solvent which cannot directly dissolve an adjacent lacquer layer. Two dielectric layers formed in this way, together with a metal coating, are 1.2 mu thick. Pref. the total thickness of 2 lacquer layers and the 2 metal coatings- 0.5 mu. The first and third lacquer layers may be of acetyl cellulose, and the second and fourth layers of polyphenyl oxide. This arrangement enables the dissolving of a lacquer layer by the succeeding lacquer layer to be minimised, thus enabling condensers to be built up of very thin layers having high insulating capacity.

Title: Alternating twist, false twister - with wandering twist point between rollers or belts with cooperating profile defining fric
Inventor: GRUNER WILFRIED DIPL ING
IPC: D01H7/92
Filed: 1973-02-02
Abstract: An alternating binding or effect twist can be produced in staple fibre or filament (or mixed) yarns. Upstream of a false twist tube is a friction twist device comprising adjacent rollers or belts with surface profiles which co-operate to define a yarn gripping, twisting point. As the rollers, belts rotate, the gripping, twisting point moves up and down the length of the rollers (several yarns can be processed along the run of the belt). This alters the upstream twisted length, and hence the twist level to give a yarn with periodically changing, reversing twist.

Title: Hand or power driven torsion over-load coupling - suitable for bench vice applications etc.
Inventor: DEGLE KARL
IPC: F16D7/02
Filed: 1973-07-12
Abstract: To improve the reliability of the spring loading factor during working life and to generally improve the latter, it is proposed to replace conventional plate spring over-load protection with adjustable wedge-shaped spring rings. The wedge-shaped springs rings - one or more pairs - are arranged so that they may be moved relative to one another by means of a co-axially fitted adjusting disc which determines the allowed torsion. With this method of construction it is possible for a hand-crank to incorporate the necessary components within its own design and thereby allow a more positive fit between it and the transfer shaft, reducing shoulder wear on the insertion shank.

Patent DE-2346123-A1 (DE)
Title: Signal generating method - signal consists of series of AF and corresponds to multiple digit information
Inventor: HELLWIG GUENTER
IPC: H04Q1/444
Filed: 1973-09-13
Abstract: Each digit is represented by a decadal system figure, to which a discrete a.f. is allocated. In case two identical frequencies follow each other, a special (repetition) frequency is generator instead of the second identical frequency. Individual digits are converted into a discrete code signal, each applied to an input of a gate, to an allocated to it comparator and to a following the latter comparator. Comparators test for equality code signals in adjacent digits. A clock pulse generator and comparators so control the gates, that the clock pulses consecutively guide the code signals through the gate to a decoder. A comparator detecting two identical consecutive code signals prevents it from reaching the decoder and causes the gate to deliver a switching signal.
Patent DE-2357507-A1 (DE)
Title: Fertility-increasing agents - contg. kininogenase and/or kinin
Inventor: HABERLAND GERT L PROF DR
IPC: A61B17/43
Filed: 1973-11-17
Abstract: Agents for increasing fertility contain kininogenase (e.g. kallikrein, akrosin or trypsin) and/or kinin (e.g. bradykinin or tallidin). They advantageously also contain kininogen (e.g. plasma). The agents are produced by mixing the active ingredients with inert, non-toxic, pharmaceutically suitable carrier substances. The agents increase sperm motility, presumably due to a favourable effect on kinin release in the spermato plasma, and can thus be used to increase the success rate in artificial insemination. Addition of the agents to semen retards ageing processes and restores sperm motility. The agents may also be administered systemically to increase fertility of male animals (incl. humans).
Patent DE-2406908-A1 (DE)

Title: Water charge cartridge with plastics casing - has variable wall thickness for ensuring sealing of borehole
Inventor: LEPPAK WILHELM
IPC: F42D1/20
Filed: 1974-03-19
Abstract: The water charge cartridge is used for placing into boreholes, for example in mines. The cartridge flexible casing ensures that it is sealed into the borehole. The wall thickness of the cartridge is varied on blow moulding so that wall sections subject to high friction are made thicker. Thinner sections ensure better tearing characteristics on exploding the explosive charge. The flexible plastics casing has a filling neck at the top of the curved section which has thicker walls in certain regions. The cylindrical section has a relatively thin wall and the domed bottom has a thick wall. This cartridge is jammed reliably into borehole due to its curvature. Material saving can be up to 50%.

Title: Belt drive for pairs of paper processing cylinders - provides flexible contact pressure between cylinder faces
Inventor: BOETTCHER ROLF DIPL ING
IPC: B65H45/14
Filed: 1974-08-16
Abstract: An endless belt drives a number of cylinder roller pairs of a paper sheet processing machine. Since the gap between the rollers have to accommodate different paper thickness, the drive belt which has spring loaded tension roller, provides the required flexibility between the rollers. The drive belt which can be of flat or round cross section, avoids the noise and lubrication problems which arise when gear wheels are used to link the roller pairs. It also prevents the excessive wear which occurs between gear wheels which are in mesh at a point other than the pitch circle diameter.
