Title: Generation of binary recordings in information carrier - using modulation and direction of polarised light pref. from laser
Inventor: ORTNER BALDER DIPL-ING DR
IPC: G11B7/004
Filed: 1973-08-17
Abstract: The process concerns the generation of binary records in a carrier with the use of a beam, which is modulated in accord with two sequences of mutually independent bits. These are then directed one after the other so that the bits are recorded in two tracks of the carrier. The process is effected by a laser beam which is polarised linearly in one direction. In its beam path is firstly an electrically-controlled, cell whose electrodes rotate the direction of polarisation. Next there is an analyser e.g. a Nicol-prism, followed by a second cell with electrodes to which modulated voltages are fed, similar to the first cell. The beam finally passes through another analyser in the form of a double-refracting prism before recording in two tracks of the medium.

Title: Window sill casing - has lateral adjustable brackets with stationary part fixed to sill, sliding part to front edge of casing
Inventor: WILBS ALFRED
IPC: E06B1/70
Filed: 1973-11-15
Abstract: The casing of the outside portion of a window sill made of some kind of metal sheet is fixed at one edge to the outside face of the window frame and the folded-over slightly sloping part usually protrudes beyond the outside edge of the sill. The width of the casing is usually such, that a reliable hold-down fixing is necessary, in order that the casing should stand up to loads and stresses from above, as well as possible lifting forces from below due to wind. The arrangement is capable of coping with the considerably varying tolerances occuring on buildings by using telescopically adjustable brackets. The sliding part carries a grooved head into which suitable extruded lips on the inside of the folded-over casing edge are hooked-in and fixed by a worm screw.

Title: Insulation or sheath measuring system - is for round wires with straight or twisted sector-shaped cores and cables
Inventor: SIKORA HARALD
IPC: G01B11/10
Filed: 1975-04-22
Abstract: A contactless diameter measuring device continuously measures the core dia. and stores the result in a store. A second dia. measuring device measures the total dia. including twice the insulation or sheath thickness. Test results from the first device pass through the store at the same speed as the wire passes throught eh extruder, so that two correct test values are compared. The difference between the two diameters is the measure for the insulation thickness.

Title: Boot release ski braking device - uses U-shaped spring wire and bowed foot plate to fold brake plates over ski upper
IPC: A63C7/10
Filed: 1975-04-22
Abstract: This ski brake consists of two U shaped wires one end of which is bent round to pass through a pivot point in a base plate fused to the upper surface of the ski. The base of the U wire passes under the bowed foot plate (2b) where it is fitted to the side of the foot plate. The wire continues through the brake plate.

Title: Coagulation of proteins in milk - by two step addition of enzymes to reduce their consumption
Inventor: LAZAROWICZ MARIA SZADKOWSKA
IPC: A23C19/068
Filed: 1975-05-26
Abstract: Coagulation of proteins and their derivs. in milk with the use of proteolytically coagulating enzymes is improved in that the enzymes are added to the milk in two steps. In the first step, the enzymes are added in an amt. which does not cause any coagulation of the casein; in particular 20-50 mg. of enzymes having a coagulating activity of 1:4000 to 1:100000 are added to 100 l. of milk (temp. 0-32 degrees C; acidity 6.0-8.5 degrees SH). In the second step, the remainder of the enzymes is added, in particular 50-1000 mg having a coagulating activity of 1-100000 (temp. 20-45 degrees C; acidity 7.0-12.5 degrees SH). The enzymes can be of animal, vegetable, microbial or fungal origin. The consumption of rennet or its substitutes during the prodn. of hard, soft and cottage cheese, is reduced by at least 66%.

Title: Polyethylene double shrink foils - having high alkyl ethanolamine content
Inventor: ARMSEN ROETGER DIPL CHEM DR
IPC: C08K5/17
Filed: 1975-07-12
Abstract: The polyethylene contains >=0.15 (0.2-0.25) wt. % added alky ethanolamines (I). Pref. (I) are N,N-bis-2-hydroxyethyl 12-18C n-alkylamines. The use of foils (i) to shrink-pack sub-units consisting of members which are shrink-packed with polyethylene foil opt. contng. (I) or (ii) to shrink-pack individual members to form sub-units which are to be shrink-packed together with a polyethylene foil opt. contng. (I) is claimed. In concns. used, (I) is evenly distributed in molten polyethylene, but migrates from polyethylene on foil prodn. Film of (I) formed on foil surface has a separating effect, to prevent sticking together in double-shrinking. At heat-sealing temps. of 140-180 degrees C., (I) re-dissolves in foil material and does not prevent heat-sealing.

Title: Continuous reversible (poly)condensation reactions - using starting materials and recycled prod. with removal of volatile by prod.
Inventor: PASCOE PETER DIPL CHEM DR
IPC: C07C67/03
Filed: 1975-08-27
Abstract: Continuous prepn. of organic condensation esp. polycondensation prods., formed in reversible equilibrium reactions, takes place with removal of volatile condensation by-prods. The starting materials, together with recycled reaction prod., are reacted under turbulent flow in a heat-exchanger. Reaction in heat-exchanger takes place by a cyclic process, at temp. above b.pt. and press. above liquefying press. of the volatile condensation by-prod. The volatile condensation by-prod. is partly removed, by lowering press., in a subsequent expansion step. The liq. condensation prods. are recycled to heat-exchanger, with the starting materials, in wt. ratio (30-200):1. Part of desired reaction prod. is discharged from expansion step, while maintaining a constant flow in total appts. Equilibrium is displaced in direction of desired prod. High conversion rates and a high degree of conversion are achieved. Space-time yields may be improved from 2 mol/1. hr. to 10-25 mol./1. hr. In an example equimolar AcOH and octanol quantities together with prod. were passed through a spiral heat-exchanger at 25 tmos. over-press. and 220 degrees C, and then to a thin layer evaporator at 15 atmos. over-press, and 215 degrees C, to evaporate water of condensation. A yield of 99.4 wt. % pure n-octyl acetate was obtd.

Title: Train location error elimination system - has line sections fitted with line loops for parallel tracks
Inventor: SCHWARZWAELDER JOERG DIPL ING
IPC: B61L25/02
Filed: 1975-10-07
Abstract: In order to locate the trains a central control station sends to trains on the line call signals specific for a line section. There is a signal transmitter (G11). This is provided at the junction between adjacent line loops (e.g. 01-11). The transmitter sends to the train a signal specific for the track, and the call signals also contain additional track information. Call signals are accepted by a train receiver only if the transmitter signal and information in the call signal refer to the same track.
