Patent DE-2911440-A1 (DE)
Title: Bulk material vertical conveyor for open:cast mining - has endless belts following parallel C=shaped paths, between which material is carried upwards
Inventor: SCHELLHORN HANS-WOLFGANG DIPL
IPC: B65G63/00
Filed: 1979-03-23
Abstract: The mechanism is intended for lifting bulk material from a low-level conveyor on to a higher-level one while the conveyor assembly is movable. Particular application is in open-cast mining operations. The conveyors are carried by a frame which contains two endless conveyor belts following a C-shaped parallel path over part of their lengths. The low-level conveyor deposits the material near the lower end of this path, from where it is carried upwards between the belts and discharged at the higher level on the other conveyor which may be carried by a swivelable outrigger.

Title: Twisted yarn draw=off funnel - has bell mouthed portion surrounded by annular portion with intervening gap and adjustable axially w.r.t. base of spinning rotor
Inventor: SLOWIAK WLADYSLAW
IPC: D01H4/08
Filed: 1979-04-20
Abstract: Twisted yarn draw-off funnel has a bell mouth portion surrounded by an annular portion spaced from the portion by an annular gap. Portion is arranged to be adjusted and fixed with a grub screw in the adjusted posn. Adjustment takes place from the base of the rotor, at which posn. the contours of the portions define a hyperbola or an arc, to a posn. axially away from the base at which the portion is disposed within the portion. Adjustment of the draw-off funnel relative to the spinning rotor base permits of avoiding damage to the yarns due to thermal effects. Fibres which are difficult to spin in known devices can be spun to yarns having satisfactory quality.

Title: Fireproof door locking assembly - operates catches on horizontal leaf edge from mortised lock via linkage
Inventor: ERNSTING UWE ING GRAD
IPC: E05C9/06
Filed: 1979-05-08
Abstract: The door assembly consists of fixed leaf and the passage leaf (2). The leaf is fitted on its vertical edge with a mortised lock (3) containing a catch (4) and bolt which engage with corresponding recesses in the adjacent vertical edge of the fixed leaf.

Title: Small PBX locally powered from mains - automatically connects to exchange line if selection fails to occur within given time
Inventor: FAHRENSCHON FRANZ DIPL ING
IPC: H04M3/42
Filed: 1979-09-13
Abstract: The system has an exchange line, a switching console, several extensions able to dial an exchange and a device to transfer and evaluate codes.

Title: Inductive pulse transducer for measuring vehicle revolution rates - maintains magnetic gap between transducer and rotor with non-magnetic cap
Inventor: NEIDHARD KLAUS DIPL ING
IPC: G01P1/00
Filed: 1979-10-06
Abstract: An inductive pulse generating transducer produces signals dependent on the rotation of a toothed disc (12), esp. for measurement of revolution rate in vehicles. It is rod-shaped and so mounted that its end (10b) and a flux-carrying rod in the rotor disc teeth (21) have a magnetic gap between them. The accuracy of the gap is maintained at the required level more economically than with similar, devices and is independent of the manufacturing tolerances of the transducer. The end (10b) of the transducer has a non-magnetic cap (22) whose lid thickness is not greater than the maximum permitted magnetic gap. Alternatively, the thickness of the cap lid may be selected to be no thicker than the maximum radial deviation of the disc (12).

Title: Mercerising knitted fabric - in which padded fabric is stenter-dried for indefinite storage
Inventor: VICO JOSE A
IPC: D06B7/08
Filed: 1979-10-13
Abstract: In a mercerizing process for, partic. knitted cotton fabrics, the fabric is impregnated with the mercerizing liquor in a pad mangle then dried under tension at a temperature of 100-120 deg.C. on a stenter. The liquor contains constituents which release stabilising gases in the drying-off. A J-box may be interposed between pad mangle and stenter to give a dwell of 30-60s. After drying,e fabric may be gassed and finally cooled before rewinding. The fabric emerges dry from this process and does not have to be immediately washed, finished and dried. It may be stored as long as necessary between mercerizing and further finishing, and has improved dyeing properties. The equipment is not exclusive to the process, and may be utilized for other purposes.

Title: Composite reinforced-concrete slab prodn. method - removes primary panel when set and inverts over unset secondary panel
Inventor: HAEUSSLER ERNST DR ING
IPC: E04C5/16
Filed: 1979-11-03
Abstract: The method produces reinforced concrete composite slabs, comprising inner and outer reinforced panels, an intervening insulation space and one or more anchors securing them together. The reinforcement for the primary panel, the first to be produced, is assembled on a horizontal mould bed, after which the concrete is poured with the anchor protruding from it. After assembly of the reinforcement for the other plate and pouring of it it is secured to the anchor. After setting, the primary panel (1) is removed from the mould and the secondary one (2) formed in it or in a similar mould, a closed reinforcing ring (8) being cast into it. The primary plate is then inverted through 180 deg. to bring the anchor (4) to the underside for insertion in the ring, and lowered onto the secondary plate, which has not yet set, and vibrated.

Title: Optimised quantisation system for PCM signals - uses signed quantisation of actual values from range giving reduced redundancy
Inventor: KEHLER WALDEMAR DIPL ING
IPC: H03M3/04
Filed: 1980-04-02
Abstract: The method is particularly suited for the optimised encoding of DPCM signals. Information is preserved by the use of the signed quantisation of actual valves rather than of the increments which could be ambiguous i.e. positive or negative. A theoretical sub division is made initially into an expected quantum (Me) and a remaining quantum (Mr). The centre of the expected quanta (Me) is determined by one or several functions (E) and optimisation of stepping is established.
