Title: Regeneratable electrical capacitors prodn - by making strong connection between capacitor films strips and cover film strip
Inventor: PREISSINGER KARL-HEINZ DIPL PHYS
IPC: H01G4/18
Filed: 1974-06-27
Abstract: Parent patent described the prodn. of regeneratable electrical capacitors by (a) leading >=2 capacitor film strips and >=1 cover film strip to a contacting position, and (b) effecting a film connection between all the films by melting connection elements that run parallel to the films, and are melted perpendicular to the films. Here the capacitor and cover film strips that are dielectrically inactive after the completion of the capacitor are firmly bonded together. Capacitors contg. dielectrics that have relatively poor regeneration properties e.g. polystyrene and polycarborate can be regenerated, as air can approach the surfaces necessary for regeneration.

Title: Dust agglomerating ducting for mine heading - flexi-plastics film withstiffener rings and water offusers
Inventor: HOELTER HEINZ
IPC: E21F5/20
Filed: 1974-09-19
Abstract: Agglomerating ducting for drivages and tunnels in the mining sector is to handle the appreciable amounts of dust produced by heading machines in the enclosed heading face area. To ease transport and assembly problems, the ducting is made from flexible plastics film material which has stiffener rings to reinforce it at intervals along its length. Also spaced at specified intervals along the ducting are water stripper rings which here take the form of welded-in offusers (2). The object of these offusers is to force the sprayed water back into the ducting from the rim zones and so re-activate it for further agglomerating duty in respect of the dust inspired from the heading. This improves the contact time and action between water and dust and so agglomerates the dust faster and with greater effect. The ducting is light enough for a 20 m length to be carried by one man.

When the chains or belts are used for snow chains or track laying vehicles, sharp protruding pins are mounted on the brackets which provide additional grip into teh snow or soil over which the vehicle rides.
Patent DE-2505119-A1 (DE)
Title: Controlled granulation of powders - combining drum and shear granulators, the second being used to feed first
Inventor: IHLEFELD KARL-HELMUT
IPC: B01J2/12
Filed: 1975-02-07
Abstract: Automatic production of spherical granular aggregates from a powdered feed, having uniform size but able to be controlled in a wide range of sizes from 022m to 30mm dia, uses a combination of shear and drum mixers. Fine granules of uniform size are produced in the shear mixer and then fed forward to a drum granulator, to which a proportion of the raw feed is fed also. The ultimate size of the granules produced is controlled by the ratio of raw feed going to the shear mixer and the drum, the more which goes to the drum, the larger the granules. Process allows for the automated production of granules from milled powder feeds, the size range being variable but being tightly controlled once this size is set. Combines the advantages of both types of granulator. The shear mixer is easily automated byt will produce only granules of small dimension. The drum granulator if fed with powder, tends to produce a wide band of granule sizes. If fed with uniform nuclei, as with this system, a controlled growth in size is achieved from the fine powder feed.
Patent DE-2509488-A1 (DE)
Title: Axial hole in spur gear tooth - reduces specific contact pressure by increasing tooth elasticity at pressure face
Inventor: PEEKEN HEINZ PROF DR ING
IPC: F16H55/16
Filed: 1975-03-05
Abstract: To increase the torque transmission capacity of a gear wheel, it is necessary to control the contact pressure on the tooth face. By increasing the elasticity of the gear tooth, it deforms more easily when a load is applied. This increases the contact area between the teeth, thus reducing the specific contact pressure. By producing a gear tooth with a hollow core (3) along the tooth axis, its deformability is increased. Lubrication oil, pumped via a central shaft hole and a cross hole reaches the core hole from where it is forced to the tooth contact surface through a hole normal to the pressure face.

Abstract: The drive is for use in bookbinding machines, particularly for holding, having a shaft in bearings at right angles to the straight sheet conveyor track, and to which the belt guide rollers are inclined. The rollers (7) are coupled to the shaft by a section of hose (22) of rubber or plastic, typically polyurethane. The hose can be slit, the sides of the slit being profiled so as to engage with each other. The system avoids the risk of slippage as occurs with a belt drive, and is reliable, easily replaced, and noiseless, and the speed of travel is kept constant.

Title: Photographic film spool winding mechanism - has axis supported on pivot arms with flanges resting on drive rod
Inventor: ISSAJEV GERD ING GRAD
IPC: B65H18/16
Filed: 1975-06-10
Abstract: The mechanism is for the winding of band-shaped material onto or off spools of corresponding width, esp. photographic film spools. The winding mechanism has two pivot arms (10) which have lateral rods to retain a spool (15) axis at one end. The opposite ends (11) of the arms have a recess for engaging a horizontal stationary rod. A shaft (8) is positioned below the rod, parallel to it, and nearer to the side wall of the appliance than the axis of the spool. The spool flanges (16) rest on the shaft, and the shaft is driven by a motor (9). The rod sided ends of the pivot arms have slots (11), with a width corresponding to the diameter of the rod. This enables the arms to be suspended from the rod. The rods are covered by an elastic material.

Title: Wall plug for bolt insertion - has filler squeezed through dowel to harden in cavity and cap groove
Inventor: FISCHER ARTUR
IPC: F16B13/00
Filed: 1975-06-14
Abstract: The fastener is anchored in a bore of much greater diameter, by inserting a binder material and allowing it to set. The dowel (1) in which the fastener is inserted is tubular near the outside, and crimped flat at its inner end, and bent into ripples. The outer end is internally threaded to hold the bolt fastener (51) which holds a blocking plate (50) against the wall. A cap is inserted in the hole around the dowel, and is a push fit so its outer diameter is greater than the bore diameter is greater than the bore diameter. There is an annular groove (52) on the inner surface of the cap insert. The filler material is inserted through the hollow dowel (1, 2) and fills the cavity completely, including the annular cap groove (52) and this holls the cap tightly in place, once hardened.

Title: Focus indicator for photographic camera - has two LED's behind sensing plate with zero phase difference indicating dead:on focus
Inventor: HOLLE WERNER DR
IPC: G03B17/20
Filed: 1975-08-22
Abstract: Focus indicator for photographic camera comprises a sensing plate on which the image is formed. Behind the scanning plate are two l.e.d.'s (9, 11) whose phase difference represents a standard for the degree of accurate focussing. The light balance has the same luminosity when in focus (zero phase difference). When the lens is out of focus, the direction and degree of deviation of the image from the local plane is indicated by their relative brightness variation which is adjusted to be independent of object brightness. The average brightness varies with object brightness to accommodate object brightness variations.

Title: Loose weave fixing equipment - takes fabric from loom for saturation with bonding fluid followed by two drying stages
Inventor: MEYER KARL
IPC: D03J1/06
Filed: 1975-09-13
Abstract: An apparatus is claimed to bond and stabilise loosely-woven fabrics, such as for mosquito netting, filters, basic floor coverings or tapestry work. As the fabric emerges from the loom it is saturated by a bonding fluid and then subjected to contact-free drying by an infra-red heater with a final drying stage by applying contact heat. The system ensures that the fabric passes directly from the loom to the fixing stage so that the fabric structure is not distorted by winding and transportation to a remote vat processing stage.
