Patent DE-2403083-A1 (DE)
Title: Continuous oil firing plant operation - in which widths of passage openings of air and fuel ducts are regulated linearly and in common
Inventor: ZEYNS JOHANNES DR ING
IPC: F23N5/18
Filed: 1974-01-23
Abstract: Firing plants are continuously operated with liquid or gaseous fuel, esp. heating oil of any viscosity. A fan produces an air stream, which can be blown into a combustion space, in a burner tube with fuel nozzle(s). The widths of openings of passage openings into the air and fuel supply ducts are regulated linearly and in common such that the difference pressures controlling the amounts of air and fuel and existing on either side of the passage openings in the respective ducts are constant, and the media flow at constant speed in the openings, whose width of opening can be varied. The working range, esp. for large plants, can be widened, with combustion of a constant mixt.

Title: Dog clutch with wedge-shaped elastomer pads - is surrounded by ring exerting radial pressure on pads
Inventor: ASMUS NORBERT
IPC: F16D65/12
Filed: 1974-02-01
Abstract: The coupling consists of a driving half and a driven half. Both halves have axially extending claws which fit with large clearances inside one another. Wedge shaped elastomer pads are mounted between the axially extending claws. The outside faces of the elastomer wedges i.e. those at the circumference of the clutch are rounded. A ring is mounted over the coupling. The bore of the ring has a number of radiused cut-outs which is equal to the number of elastomer wedges. The radius of the cut-outs is larger than the radius of the outside faces of the wedges, so that when the ring is rotated, the elastomer wedges will be jammed between the claws of the coupling.

Title: Fabric fluid treatment process - uses vertical fabric feed channel formed by extened upper-lower bath walls
IPC: D06B3/28
Filed: 1974-03-27
Abstract: The system to pass a fabric through a rinsing fluid, where the fabric is required to dwell for a period, has the upper and lower walls of the bath curved to form a narrow vertical inlet for the fabric with walls to give the fabric feed channel. The system ensures that the fabric is fully immersed in the fluid, without developing air bubbles which remain in one place on the fabric, and without allowing lightweight fabrics to float to the surface of the fluid.

Title: Dust suppression in fully mechanised coalfaces - film lagging drawn off roller and bonded to roof with pressure roller
Inventor: POLLER DIETER ING GRAD
IPC: B29C63/30
Filed: 1974-05-29
Abstract: Dust suppression system for fully mechanised coalfaces employing powered supports is based on the use of film lagging.

The storage roller can be mounted directly on the machine, or else form a separate unit in the form of a tender or trailer. The roller should have an atomiser to spray the adhesive onto the film and/or onto the roof for lagging. The film container and/or the area in which the film is reeled off should be shrouded to keep dust out with the aid of overpressure. It is also possible to apply the film by extensible forepoled members.

Title: Remote controlled missile systems - use fibre optic transmission lines of low loss to transmit control signals to missile
Inventor: QUAST ARMIN DIPL ING
IPC: F41G7/32
Filed: 1974-07-13
Abstract: Remote control of short range missiles or floating objects is effected by broad bend optical signals transmitted through a fibre optic bundle. A television camera (4) is located in the nose of a missile (2) in either a fixed or movable position. Signals from the camera are transmitted to an encoder (6) operating a modulating laser (8) to provide conversion to optical signals. The optical signals are fed into the fibre optic bundle (12) which is stored in a coil (14) so that it can pay out as the missile leaves the launching pad. An optical coupler and photo diode converts the optical signals to electrical ones that are decoded for display on a C.R.T.

Title: Erosion protection nets for sea shore bottom - are held on posts for reducing energy of breaking waves
Inventor: PIGGE HANS DR
IPC: E02B3/04
Filed: 1975-04-24
Abstract: The arrangement for protecting the sea coast against erosion caused by waves uses nets placed close to the coast.
