Title: PVC- and plasticiser-free foamed sealing and insulating materials - mfd. by spreading dry blend contg. thermoplastic, filler, blowing agent etc. on support melting, smoothing and foaming at elevated temp.
Inventor: MUELLER NORBERT DR
IPC: B05D3/12
Filed: 1992-07-10
Abstract: A process for the prodn. of latex-, PUR-, PVC- and plasticiser-free sealing materials (I) contg. among other things, a foamed layer, comprises spreading the amt. of powder mixt. (II) corresp. to the required foam thickness onto a supporting layer (A) consisting of release paper, cover film or reinforcing web, melting at 70-140 (pref. 70-120) deg.C, smoothing between flat rollers and foaming at 120-200 deg.C. Mixt. (II) contains 100 pts. thermoplastic polymer (III), 0-100 pts. filler, 0.5-7 pts. blowing agent and 0-30 pts. auxiliary substances. Also claimed is mixt. (II) as above, in which (III) has MFI 190/2.16 = 2.5=80, pref. 5-40, and crystallite m.pt. 70-140 (pref. 70-120) deg.C. Also claimed is a mixt. for use as a primer or lining for the foam layer, with the same compsn. as (II) but without blowing agent and activator. Also claimed are sealing and insulating materials (I) obtd. by this process. USE/ADVANTAGE - Used esp. for interior linings in cars. The process enables the prodn. of environmentally more acceptable materials contg. no latex, polyurethane, PVC or plasticiser. With the above powder mixt., it is possible to produce homogeneously distributed layers 2m or even 4-5m wide on commercial powder spreading machines (contrast prior-art mixts.); after passing through the drying oven, this gives homogeneous foam of uniform thickness, without sepn. of components.

Title: Verifiable reliably decoded data transmission procedure - comparing transmitter message with receiver message to verify transmission of secret message when they agree
Inventor: DOERFLER REINER DR
IPC: G07C9/00
Filed: 1992-07-15
Abstract: Encoded data are transmitted between a transmitter (S) and at least one receiver (E). When the transmitter (S) is activated, a transmitter message is provided which includes a cryptogram, or secret message, a variable transmitter code and a constant control message specific to the transmitter (S). The cryptogram is generated by combining a plain text from the data with a variable code text from a code generator. On activation of a receiver (E), a receiver message of the same form and content of that of the transmitter (S) is formed and compared to the transmitter message. The transmitted data are then verified at the receiver (E) when the message tally. USE/ADVANTAGE - E.g. in remote control of vehicle door lock. Ensures message is accurately decoded and reduces noise in simple transmission system.

Title: Hydraulic system for e.g. injection mould - operates some units such as extruder on open circuit but others needing precise movements of heavy masses are moved by closed circuit
Inventor: DANTLGRABER JOERG
IPC: B29C45/82
Filed: 1992-08-27
Abstract: Hydraulic system supplies consumer points in series in an hydraulically controlled layout and partic. an injection moulding machine with pump and flow pressure regulator. One of the consumer points e.g. the extruder, injector or possibly the ejector is operated in the open circuit, whereas a selected point e.g. the closure unit, for which a greater mass has to be moved in alternating directions, is moved in the half-closed or closed circuit. The diagram shows an example of an injection moulding machine in which the consumer points (12-20) are fed by a pump (10) with regulated vol. displaced and driven by the motor (22). The points (12-18) are those for which precise time control on their acceleration and braking are not so important such as the extruder etc. The point (20) however is specifically selected as one where are large mass must be accelerated or retarded with precise timing, such as the closure unit. The arrangement of moving it in the half-closed circuit dispenses with any need for additional proportional valves. ADVANTAGE - The system permits finely controlled braking even with heavy masses. It has a relatively simple construction and corresp. simple controls.

Patent DE-4231470-A1 (DE)
Inventor: SCHALZ KARL-JOSEF DR
IPC: G02B21/24
Filed: 1992-09-19
Abstract: Proposed is an ergonomically designed modular microscope system assembled from basic modules (1 to 4) to which additional modules can be directly (10) or indirectly (11, 12; 13) linked. The individual modules forming the basic microscope unit have inside them precision stop surfaces located on protuberances (14 to 16; 23) on the housing or dividing walls (17) inside the housing which are integral with the basic modules. The individual optical, mechanical, electrical and/or electronic components are pre-aligned on flat (24) or three-dimensional supports (56) before final assembly. The modular design of the microscope system proposed enables it to be manufactured as an easy-to-maintain assembly, avoiding the necessity for time-consuming alignment and adjustment checks. It is simple to retrofit ready-assembled modules, thus making it possible to uprate, reconfigure or downrate the system without affecting system integrity, without the need for complex conversion work and without sacrificing any of the ergonomic or other aspects of the design concept. Finally, the discontinuous "stilt" or "post" mounting design protects the system from damage due to the action of heat, and also enables savings to be made in materials.
Patent DE-4234163-A1 (DE)
Inventor: MAY KARL
IPC: F23G5/20
Filed: 1992-10-09
Abstract: Waste (a) is charged to a pyrolysis drum (2). The carbonisation gas (s) generated therein is passed into a combustion chamber (8). The flue gas (r) formed therein is fed via a cooling device (10) and via a gas compressor (16) to a stack (20). By means of a control system (24, 70), the speed of rotation (nI) of the gas compressor (16) is controlled as a function of the pressure (p) in the gas path between the pyrolysis drum (2) and the gas compressor (16) in such a way that the speed of rotation (ni) is reduced when the pressure (p) is reduced. Preferably, a further gas compressor (54), whose speed of rotation (nII) is controlled correspondingly, is connected in series with the gas compressor (16). A further pyrolysis drum (52) can also be provided. <IMAGE>

Title: Substrate with visible information protected against copying - prepd. with combination of adjacent fields of emitting and remitting colourants of almost same nuance when viewed without fluorescence
Inventor: BERNETH HORST DIPL CHEM DR
IPC: G03C5/08
Filed: 1992-10-26
Abstract: Substrate with visible information protected against unauthorised copying has information applied with a combination (I) of emitting colorant(s) (II) and remitting colorant(s) (III) with (almost) the same nuance when viewed without perceived fluorescence. (I) is applied in such a way that the different colour fields (almost) touch each other. The protection process is also claimed. ADVANTAGE - The eye cannot differentiate remission and emission radiation and perceives both as an overall colour impression, whereas the sensor of a copier measured only absorption and is blind to emission radiation. With (I), a coloured pattern, which is recognisable in the original, becomes a monochrome spot in copies. Several (I) can be used to produce complex coloured patterns.

Inventor: MEDVESCEK MILAN
IPC: G05D27/00
Filed: 1993-04-13
Abstract: Diaphragm-controlled combined flow-temperature regulating valve, in which the temperature actuator drive acts on the valve disc via a curved link and a curved plunger.

Title: Plugging resins
Inventor: BELZNER WINFRIED
IPC: C09J4/00
Filed: 1993-05-12
Abstract: Anchors are fixed into solid elements, for example walls, concrete, etc., using, in particular, cold-curing unsaturated reaction systems and epoxides. The binders used here are always reactive resins mixed with reactive thinners, giving a suitable viscosity of the system. Some of the resins used here are expensive to produce. It is intended that the new resins should be synthesisable from simple, readily available and inexpensive components, but nevertheless achieve the usual strength values. In addition, the components should be less toxic and enable the desired viscosity to be established in a simple manner. The combination of a polymer which cannot be polymerized by means of free radicals with reactive thinners containing at least two (meth)acrylate groups gives a suitable plugging resin. The polymer is preferably based on polymethyl methacrylate and the reactive thinners preferably have, as methacrylate, a molecular weight of </= 300 and a dissolving power of at least 10% for a moderate molecular weight polymethyl methacrylate. Production of ampoules or cartridges for fixing anchors.
