Patent DE-4002417-A1 (DE)
Inventor: ALTENBACH KLAUS DR
IPC: C08L21/00
Filed: 1990-01-27
Abstract: Production of non-aqueous resorcin-formaldehyde condensation products with low average molecular weights containing no undesirable proportions of free resorcin by the acid-catalytic condensation of resorcin with formaldehyde or a formaldehyde derivative at high temperatures in an inert organic solvent with the azeotropic, distillative separation of the reaction water, whereby the reaction takes place in an apolar solvent which is not miscible with water in which resorcin dissolves readily but the resorcin-formaldehyde condensation product dissolves only with difficulty and is specifically heavier than the solvent or reactant solution so that two fluid phases ar formed, the lower of which consists of molten condensation product. The solvent is preferably fed back in the circuit from the water separator into the reactant solution through the lower phase and the condensation product is extracted from the lower phase. It may be freed of undesired resorcin contents by subsequent further solvent extraction. Use for condensation products as adhesion promoters in technical rubber articles containing steel or textile cords or for the production of waterproof wood glue and textile impregnants.

Title: Bath drain-water processing unit - has surge-arresting and initial-cleaning vessel upstream of tank
Inventor: SCHULTE FRIEDRICH WILHELM
IPC: F24D17/00
Filed: 1990-02-22
Abstract: The compact unit prepares water drained from a bath and washing machine for re-use by pumping into toilet-flushing tanks or for cleaning.  Waste heat from it is utilised by means of a heat-pump to provide washing water. A vessel (10) connected upstream of the drainwater tank (20) acts as a surge-arrester and has an initial cleaning effect.  There can be a filter with two elements and a drain outlet mounted directly on the tank.  This is so designed that water dripping from it can re-absorb oxygen, thus reducing odour. USE/ADVANTAGE - Compact, water storage and recycling unit with economy of water, and largely automatic in operation.
Patent DE-4010482-A1 (DE)
Title: Minimising mist formation of flowing test gas - by relaxing pressure in cooled filter cavity with immediate absorption of evolved moisture
Inventor: SCHWEIKERT DIETER
IPC: G01N1/40
Filed: 1990-03-31
Abstract: To prevent formation of mist and aerosols in gas being cooled before delivery to a treatment unit or analyser, the gas is fed into a hollow filter body inside the cooling unit. In the filter cavity the gas pressure drops, with evolution of aerosols and mist. With pressure and temp. at normal levels, these materials are absorbed by the filter material, with the gas then leaving the cooler towards the test unit. ADVANTAGE - Falsified results and/or damage to appts. are avoided without complex further equipment.

It is enclosed by first and second walls(1,3,), the first one being of silicon carbide. This wall can can as a radiation receiver, forming a concentrated bundle of rays, and it can be concave. The body can be enclosed by convex and concave walls. ADVANTAGE - The heat-transferring metals will not burn away under air penetration.
Patent DE-4013087-A1 (DE)
Title: Pulse width modem for magnetic and optical data carriers - carries out integration while specified number of extra integrators transmit output signal in background
Inventor: BOBZIN DIERK
IPC: H03K7/08
Filed: 1990-04-25
Abstract: The process is used for pulse width modulation and demodulation, esp. for recording of video signals on magnetic and optical data carriers, the so called parallel modulation. The video signal to be modulated is supplied to the modulator after processing in a clamping amplifier. A used ring counter consists of a shift register with only 1 bit set. The active bit controls three MOS FET switches such that video signal is supplied for integration to a capacitor via the first switch. For demodulation no filtering of the video signal is required, as a continuous video signal is formed by switch-off delay of the output phase.
Patent DE-4015071-A1 (DE)
Title: Surfacing injection mouldings with film - by placing surface film plus barrier film in mould before injecting thermoplastic shot behind them and bonding all materials together
Inventor: MISCHKE JUERGEN DIPL PHYS DR
IPC: B29C45/14
Filed: 1990-05-11
Abstract: Surfaced plastic mouldings are produced by injecting thermoplastics behind a layer of the surfacing material in a mould. A separating film is placed behind the surfacing film already in the mould; the thickness and stiffness of this separating film depend upon the temp. and pressure used, so that when the thermoplastic is injected into the mould it flows along the smooth separating film without moving it; when the mould is filled this film is sufficiently fused and/or softened, by the temp. and pressure used, to weld or bond to the thermoplastic and to the surfacing film such as a fabric.

Title: Process for recovery of energy - utilises its own energy, ambient temp. and temp. difference is inversely proportional to increased volume
Inventor: PEYLO ANDREAS
IPC: F24V50/00
Filed: 1990-08-11
Abstract: Ambient temp. is divided into an optional number of media (102, 103, 104 ...) and areas (2,3,4).  Medium (102) is subordinate to medium (101) in area (1) and so on, each succeeding heat medium being subordinate to the preceding ones. An amount of energy (14b) passed to medium (101) will be emitted to the desired number of subordinate media (102, 103, 104 ...) by means of energy utilising devices (13a, b, c ...) linking the areas (2, 3, 4 ...). USE - Utilises energy which would otherwise dissipate into infinity.

Title: Method of producing cutting bevel on mower blade - involves dual stamping process after which projecting edge is ground off in line with general plane
Inventor: SCHUMACHER II GUSTAV
IPC: B21D53/64
Filed: 1990-08-20

A second stamping process forms the tip of the cutter, and the projecting underneath portion of the blank (1) is then ground off. Alternatively in the initial process a turned up edge strip is produced and this is subsequently ground off to give the same result. USE/ADVANTAGE - Produces a shallow bevel with minimal grinding.

Title: Three=dimensional digital data memory - uses several electromagnetic or particle beams etc. impinging from outside into memory for changing memory substance
IPC: G11C13/04
Filed: 1990-08-29
Abstract: The digital data are stored in a three-dimensional structure or material. Several beams of electromagnetic waves, particles, etc., penetrate from outside the memory for writing or reading the respective information with a double energy release at the respective point, i.e. the intersection of the beam. Thus, they cause a change of the substance for subsequent detection, e.g. by CCD. The entire spatial shape is penetrated by mostly parallel metal fibres, semiconductor strands, etc. with orthogonal intersection. Thus, the substance is changed by current flow between the intersection point fibres, etc. USE/ADVANTAGE - Replacement of magnetic discs, CDs, etc., with a facility of mfr. without further research in the field of holography.
Patent DE-4030659-A1 (DE)
Inventor: HAHNE JOCHEN DIPL ING
IPC: B61H13/26
Filed: 1990-09-28
Abstract: The largely automatic resetting of the brake linkage of brake devices, in particular of shoe brakes for railway vehicles, takes place usually by means of single-action or double-action linkage actuators at the start of the associated brake linkage chains. In the case of longer brake linkage chains, the resetting can no longer be compensated solely by the linkage actuator and the positions of the brake levers at the end of the chain can become so unfavourable that adequate functioning of the brake device is no longer ensured. So that additional manual resetting of the brake linkage can be largely dispensed with and the efficiency of the brake device improved, in a brake device of the generic type at least one further linkage actuator is arranged in series in the brake linkage chain behind a forward-mounted linkage actuator. The required resetting path for the linkage actuator which is respectively mounted downstream is determined by the control stop which is coupled relatively to the forward-mounted linkage actuator limit point. The control stop of the respectively forward-mounted linkage actuator is arranged so as to be longitudinally displaceable on the frame in relation to the linkage actuator and is connected to the linkage actuator which is arranged after it. <IMAGE>
