Title: Carpet steam treatment unit - where removable lower rollers are shrouded by troughs to support lower loops of carpeting
IPC: D06C7/00
Filed: 1973-05-19
Abstract: As the carpeting passes through the steam unit following a serpentine path between upper rollers and lower supports, the lower trough supports are fitted with vertical slits in their end faces to carry a support roller which can be removed, or replaced with a roller of a different dia. The purpose is to extend the application of the lower support trough, for carpetings of acrylic pile fibre which must not be subjected to pressure, by inserting a roller to allow polyamide carpetings to be processed where light pressure gives a denser and more consistent pile structure.

Title: Rope drum for lowering and lifting of loads - has clutch actuated by safety link in contact with rope
Inventor: MUELLER KARL-HEINZ
IPC: B66D1/54
Filed: 1973-07-14
Abstract: The winding rope drum mechanism has a dog clutch which is disconnected when the rope goes slack. When the rope is tight then the protection mechanism prevents inadvertent or intentional release of the clutch. The rope is in contact at all times with a transverse bar which is connected by side members to an actuating cam. The transverse member rests on the lifting rope and follows its movement by its own weight. When the lever in contact with the rope rotates due to the slackness of the rope then the cam is rotated along with it and disengages the dog clutch. Operation is reversed when the rope tightens up again.

Patent DE-2346857-A1 (DE)
Title: Distillative sepn. of soln. contg. non-evaporating component - using vapour diffusion promoted by heat of mixing
Inventor: KNACKE OTMAR PROF DR
IPC: C02F1/08
Filed: 1973-09-18
Abstract: A method of distillative sepn. of solns. contg. a non-volatile component utilises the heat generated by spontaneous distillative mixing of two solns. of differing chemical potential to produce the distillative sepn. of another soln. Pref., the spontaneous distillative mixing takes place between two solns. of differing concns. In the prefd. arrangement, a number of closely spaced, vertical walls have liq. films trickling down both their surfaces; the succession of films is as follows: first and fifth film is a soln. of lower concn., second the same but at higher concn.; third film is the soln. to be sepd., and fourth film is of the pure volatile component. Differential vapour pressure causes the volatile components from first film to evaporate and, by diffusion across the mixing chamber to ppte. on the second film, thus releasing heat which passes through the wall to the third film, where it causes evaporation of the volatile component, which in turn diffuses across the sepn. chamber to the cooler surface on which the film of pure volatile component is pptd. Extremely high thermal efficiency, resulting from the elimination of conventional heating and cooling processes in evaporation and similar systems.

Title: Continuous pasting of lead accumulator grid plates - using mixer-kneader-extruder to produce paste strip, for uniform prod
Inventor: SASSMANNSHAUSEN GUENTER DIPL C
IPC: H01M4/20
Filed: 1973-12-05
Abstract: In the continuous prodn. of the grid plates for Pb accumulators by mixing Pb oxide dust (Pb + PbO) to a paste successively with water and H2SO4, cooling and pressing into the grid spaces, the dust is ground before mixing to increase and equalise its surface activity and the paste is pressed through a die of a suitable size and shape in the form of a thin, wide, cohesive strip, whilst the grid is passed to or under this strip, which is pressed into the spaces. The paste pref. is extruded through a wide slit die and pressed into the grid spaces by rolling. The water used for mixing can also contain additives needed for negative grid plates, e.g. BaSO4, C black, lignin derivs. and/or storage stabilisers. The mixt. can be stabilised by adding high-mol. water-soluble polyethylene oxide, pref. in a amt. of 0.05-0.5%, before adding the water. Grinding and mixing are carried out in a 2-shaft mixer-kneader-extruder, with 2 adjacent worm shafts, turning in the same direction, in an 8-shaped twin-screw housing. This continuous pasting process gives good homogeneity and uniformity in wt. and dimensions, so that the plates have reproducible physical and chemical properties. The proces is simple and suitable for mass prodn. and the closed construction reduces the lead dust level in the factory.

Title: Mine heading machine jib tool controls - template responds to gyro and reflected light signals
Inventor: SCHNELL GUENTER DIPL ING
IPC: G01C7/06
Filed: 1974-06-08
Abstract: Mine heading machine jib tooling adjustment system limits tool movements to the section of the roadway as defined by a laser mean and consists of a template which reproduces the roadway section, can adjust in its plane as well as rotate and is scanned by a reflected light barrier and operates in conjunction with a laser located receiver surface emitting signals to indicate deviation on the part of the machine. Two gyroscope systems, with horizontal and vertical axes respectively are positioned in transverse planes within the road and link up with devices responsible for emitting signals to indicate angular deviation or listing on the part of the machine. The signals, proportional to the deviation of the respective axes, correct the real-life tool position coordinates. Signals from the receiver control the movement of an adjuster which in turn adjusts the template in its plane and the light barrier adjusting mechanism.

Title: Bit error rate measuring device - has receiver end circuit for widening of its measuring range using quasi-random signal trains
Inventor: HANKE GERHARD DIPL ING
IPC: G06F11/00
Filed: 1974-10-30
Abstract: The device uses as test signals quasi-random signal trains generated in shift registers with a feedback. The received test signal train with a length z = 2n - 1x and a high bit repetition frequency fb is applied to a series-parallel convertor which transmits at least one quasi-random signal train of the same length, but of a frequency fb/2n. This test signal train is used as an input signal for at least one bit error rate measuring device operating at a timing frequency fb/2n. At error distribution over the measuring path the convertor is preferably formed by a single-stage AND-, NAND-, or OR- circuit. The single quasi-random signal train, subdivided in the bit repetition frequency is then used as the input signal for a single bit error rate measuring device.
