Patent DE-4023923-A1 (DE)
Title: Reagents mixer for making floor coatings - is mobile appts. with reagent tanks, metering devices, outlets to mixing container and movable stirrer to enter reagents or mix
Inventor: WASMER KLAUS
IPC: B29B7/74
Filed: 1990-07-27
Abstract: Equipment is designed to convey and mix two-part materials and to discharge the prod. e.g. for coating industrial floors; the two reagents, pref. a resin (e.g. epoxy) and its hardener or similar, are conveyed separately to a mixing container before the mix is applied. Two chambers, which are connected at least when in operation for the respective reagents, can be moved and each has a valve on its outlet, behind which it has a metering device; the mixing chamber receives the reagents from their own chambers which are fitted with stirrers. More specifically, the two chambers (3, 4) hold the reagents and are fitted with outlet (5) valves. A balance (9) weighs out the quantities discharged into the mixing chamber (10); the main framework holds a stirrer (12) and the equipment is mobile on wheels (15). The reagent chambers (3, 4) are mounted so that they can be removed easily for filling and then replaced in position.  The metering device (9) can control the outlet valves (22) to allow set quantities to be fed to the mixer. The stirrer system has horizontally moved (26) vertical shafts (25); it is mounted so that the stirrer can be inserted into the reagent chambers (3, 4) or moved to dip into the mixing container (10). ADVANTAGE - The appts. minimises the costs of the reagent containers used and, in partic., greatly reduces material losses (compared with existing equipment for the same purpose).
Patent DE-4028799-A1 (DE)
Title: Fuel processing system for four stroke IC engine - supplies petrol vapour with strongly differing amounts and concns. of petrol-air mixtures
Inventor: WOERSDOERFER ACHIM
IPC: F02D19/02
Filed: 1990-09-11
Abstract: The mixing system produces a mixture of petrol vapour, air and liquid petrol necessary for the combustion. An electronic regulating unit is provided which, by measuring and evaluating the residual oxygen content in the exhaust gas, alters the adjustment of the mixture. Balance pressure regulators are provided which are regulated w.r.t. the suction to supply the required amounts of air or petrol vapour to the mixture. Fuels can be used with heat values reduced to 100 kWh/per m.m. If the heat value falls too much petrol can be supplied via a separate supply line. The mixer, if required, can also be supplied with air controlled by vacuum valves. USE/ADVANTAGE - Allows use of petrol with varying calorific values. In petrol stations or refineries with first cleaning stage hydrocarbon content can be reduced to give simultaneous redn. of hydrocarbon emissions at engine exhaust.

(d2) of the bottle neck (16). ADVANTAGE - The rupture disc can be removed by hand safely, easily and rapidly.
Patent DE-4032385-A1 (DE)
IPC: B60N2/00
Filed: 1990-10-12
Abstract: The invention concerns a safety device fitted in a vehicle with at least one seat (1) which can be adjusted longitudinally and can be held by an arresting device (60). To increase the supporting action of the seat, the front edge (seat cushion part (17)) of the seat can be raised by means of a lifting mechanism (rocking lever (15), guide roller (14)). The invention calls for the inertia and kinetic energy of the vehicle seat (1) to be used in the event of a collision to actuate the lifting mechanism in such a way that an unlocking element (element (9) with a predetermined break point) frees the way for the seat to move longitudinally, and so that motion-transmission means (cable (13)) are connected to an anchor point (11) and to the lifting mechanism fitted to the seat (1).

Title: Removal of ammonia from aq. solns. from liq. manure work up - by reacting aq. solns. of nitrogen cpds. with high mol. acids, but sepg. the reactants with semipermeable membrane
Inventor: LOTTERMOSER MANFRED DIPL PHYS
IPC: C05C3/00
Filed: 1990-11-19
Abstract: The solidification of liquid manure according to DE3832349 is improved by keeping the aq. solns. of N-cpds separate from the high molecular acids during the reaction with these acids to form salts, using a semipermeable membrane. USE/ADVANTAGE - The process further reduces the already low residual ammonium content of the water, as water contg. only traces of ammonium ions can develop a smell as soon as it comes into contact with large areas of alkaline soil. the ammonium ions migrate from the contaminated solns. through the semi-permeable membrane and react with the acid on the other side. The same applies to other low molecular N-cpds present in liquid manure

Patent DE-4109625-A1 (DE)
Inventor: KARBACH BERNHARD
IPC: G01N29/26
Filed: 1991-03-23
Abstract: An ultrasonic measurement process is disclosed for measuring the wall thickness variation in the region of the welding seam (20) of a pipe (22). At least two testing heads (28, 30) are each acoustically coupled to the pipe (22) by a water jet (32). The testing heads are moved together in relation to the pipe, parallel to the axis (24) of the pipe. At least the first testing head is moved back and forth across the axis (24) of the tube, crossing over the welding seam (20). The second testing head (30) either emits acoustic radiation into the pipe (22) always outside the welding seam (20) or also crosses the welding seam (20), but at different moments in time than the first testing head (28). The signals of both testing heads (28, 30) are processed in a measurement value processing circuit (40) in such a way that simultaneously occurring measurement value deviations supply no output signal.

Title: Insulated pipeline with leakage detection - uses high resistance bare conductor and connecting wires through insulation to locate insulation breakdown
Inventor: BRANDES BERND
IPC: F17D5/06
Filed: 1991-07-25
Abstract: The insulated pipeline has three conductors fed through the insulation jacket, along the length of the pipe.

The slide surace (9) is bent, with its concavity facing the component (10). At the free end of this surface there is at least one stop roll (11). It is mounted below the slide surface (9) with a part of its circumference protruding above this surface. The position of the rolls (1) and the stop roll (11) can be altered relative to the surface (9) and the cruciform wheel (6). USE/ADVANTAGE - The device can be used in metal working industries. It allows elongated components without rotational symmetry (and with different aspect ratios of the cross section) to be reliably turned in steps onto each side.
Patent DE-4141515-A1 (DE)
Inventor: KNUDSEN JERRY A
IPC: B29C45/26
Filed: 1991-12-16
Abstract: An injection molding manifold for distributing pressurized melt from a common inlet to thirty two outlets. The steel manifold has rear and forward plate portions which are integrally brazed together. The rear portion is drilled and plugged along a first transverse plane to provide the melt passage with branches from a common inlet portion to four intermediate portions. Four sets of matching grooves are machined in the joining faces of the rear and forward portions whereby each intermediate portion of the melt passage in turn branches along a second transverse plane to eight outlet portions, each leading to a cavity. The combination of the melt passage branching in several different directions in two different transverse planes with the second plane having different sets of curved portions allows the melt passage to have a large number of outlets while still having smoothly curved bends without having a leakage problem. <IMAGE>
