Patent DE-3544770-A1 (DE)
Inventor: CHMELIR MIROSLAV DIPL CHEM DR
IPC: C08F2/10
Filed: 1985-12-18
Abstract: The present invention relates to a process and an apparatus for the continuous production of polymers and copolymers of water-soluble monomers particularly arcylic acid and/or methacrylic acid, optionally with additional comonomers, by the polymerization of an aqueous monomer solution that is introduced into the trough that is formed by an endless conveyor belt. The trough-like shape of the conveyor belt changes continuously into an extended flat profile during the polymerization process; starting from the side edges and working towards the center of the trough formed by the conveyor belt, the resulting polymer gel strand is released continuously during the transition of the curved trough-like shape of the conveyor belt into the extended, flat form.

Title: Heat exchanger, in particular for a heating and/or air conditioning system of a motor vehicle
Inventor: HALDER PRASANTA
IPC: F28F9/26
Filed: 1985-12-21
Abstract: In a heat exchanger for a heating and/or air-conditioning system of a motor vehicle, two heat exchanger blocks are coupled to one another by a connecting piece. The two heat exchanger blocks consist essentially of identically constructed bundles of parallel tubes, and are arranged next to one another in such a way that these tubes are aligned approximately coaxially with one another. The ends facing one another of the tubes of the two heat exchanger blocks open into the connecting piece, while water boxes are provided on the averted free ends of the tubes. In order to reduce the pressure drop inside the connecting piece, and to prevent so-called "dead water", the connecting piece has passages which are separated from one another in a leakproof manner and are of approximately the same cross-section as the tubes. The individual tubes, aligned coaxially with one another, of the two heat exchanger blocks are connected to one another with the aid of these passages. The passages are constructed essentially rectilinearly and arranged approximately coaxially with the tubes.

Title: Parallel-axis rotary engine with contact-free contra-rotating oval pistons
Inventor: SPEIDEL KARL
IPC: F01C1/28
Filed: 1986-06-23
Abstract: The parallel-axis rotary engine with nine contra-rotating oval pistons, which either touch one another only slightly or, preferably, turn contact-free, demands an especially sensitive detailed design in which each individual measure places extreme demands on creativity. Of especial importance is the obtaining and maintaining of a precisely defined and monitored sealing gap and optimisation of the piston body structure in order to permit a favourable labyrinth effect. The distance of the eight outer piston shaft bearings, automatically adjustable as necessary in the operating condition, from the central piston shaft bearing and from the respectively adjacent outer piston shaft bearings represents an important prerequisite for correct running of the engine. The distance adjustment in turn necessitates a suitable transmission design, the most advantageous characteristics being ascribed to the double chain or toothed belt drive. In its overall concept, the nine piston engine may be described as the most perfect rotary engine which is technically feasible.

Title: Traffic system of the future
Inventor: GRESSER GERMAN
IPC: B61B13/08
Filed: 1986-07-31
Abstract: The disadvantages of today's means of transporting passengers and goods, that is to say cars and railways, are considerable and in principle insoluble even when these means are developed further, unless completely new technologies are adopted in the field of transportation. According to the invention, it is proposed to this end that the most modern railways, namely the known magnetic levitation trains, be combined technically with the modified cars which are also known, and designed in such a way that only the respective specific advantages of each system can be realised. This is realised in that a magnetic levitation railway which travels suspended from carriers is equipped with suitable gripping devices and the motor vehicles to be transported are provided with counter-couplings so that the motor vehicles can be automatically grasped, coupled and transported along.
Patent DE-3632598-A1 (DE)
Title: Component consisting of at least one NTC thermistor and of at least one PTC thermistor
Inventor: KLOIBER GERALD
IPC: H02H9/00
Filed: 1986-09-25
Abstract: An NTC thermistor (10) which is intended to limit the current flowing when an inductive load (12) is switched on can be heated by a PTC thermistor (11). The heat flux flowing from the PTC thermistor to the NTC thermistor is so large that the temperature and hence the resistance of the NTC thermistor remain virtually unchanged even if the current flowing through the NTC thermistor is reduced. The dynamic damping of the NTC thermistor is in consequence reduced. <IMAGE>

Patent DE-3633312-A1 (DE)
Title: Magnetically operated valve, acting, in particular, as a safety valve
Inventor: NEUHAUS ROLF DR ING
IPC: B60T8/36
Filed: 1986-09-30
Abstract: If a valve with a cylindrical slide remains in one end position for a prolonged period of time, particularly in the end position in which a consuming unit is connected to the tank of a hydraulic system, then the friction between the cylindrical slide and the housing bore can become so large due to separation of the hydraulic gap flow that the valve sticks when it is to be switched over. The danger of sticking is avoided by means of an additional pulsating signal which is impressed on the signal current applied to the magnet coil in the end position and keeps the cylindrical slide in continuous motion so that the lubricating film between the cylindrical slide and the housing bore is maintained.

Patent DE-3707784-A1 (DE)
Title: Multi-component inlet port for four-stroke engines
Inventor: AUGUST RAIMUND
IPC: F02B75/02
Filed: 1987-03-11
Abstract: The invention relates to an inlet port for four-stroke internal combustion engines. Said inlet port permits an improved control, adjusted to engine conditions, of the inlet swirl coefficient, whilst maintaining a high rate of air flow. The known designs have the disadvantage that the rate of air flow falls sharply as the engine speed increases. The invention avoids this disadvantage in that a rotationally symmetrical inlet funnel forms the inlet port end between a valve bridge, carrying the inlet valve, and the valve seat ring, and a plurality of secondary ports with differing longitudinal and transverse inclinations in relation to the inlet funnel axis open into the inlet funnel and/or its circumferential surface from above. The valve bridge may be fixed separately and at the same time contain the valve gear. The inlet swirl is controlled by the differing degree of throttling of the secondary ports opening into the inlet funnel. The inlet funnel can also form one unit together with the valve seat ring, a swirl cage and the valve bridge, and can be inserted into the cylinder head as a valve assembly. <IMAGE>

Title: Apparatus for the production of yarn or twine
Inventor: SCHUMANN KLAUS
IPC: D01H4/04
Filed: 1987-03-20
Abstract: The invention relates to an apparatus for the production of yarn or twine, consisting of three rotationally symmetrical bodies which are driven in the same direction and the outer surfaces of which are arranged close to one another and which are surrounded by a guide body having a circular inner cross-section, there being contact between the inner face of the guide body and the rotationally symmetrical bodies, in which apparatus the formation of the yarn or twine takes place by twisting together the constituents of the yarn or twine between the rotationally symmetrical bodies at the centre point of the guide body, and on which apparatus is arranged a feed device for the constituents of the yarn or twine. The object on which it is based is to reduce the outlay in terms of the space requirement arising as a result of the overall height. The object is achieved in that one rotationally symmetrical body (1) is shorter than the other two rotationally symmetrical bodies (2, 3) and the feed device (14) for the constituents of the yarn or twine (15) is arranged in the region in which only the long rotationally symmetrical bodies (2, 3) take effect - Fig. 1 -. The invention achieves the technical effect that the feed device for the constituents of the yarn or twine is arranged in the height region of the rotationally symmetrical bodies.   <IMAGE>

Title: Underground structure in groundwater-bearing earth
Inventor: KASSMANNHUBER JOHANN DIPL ING
IPC: E02D31/02
Filed: 1987-04-01
Abstract: An underground structure in groundwater-bearing earth has a roof slab (14) resting on deep-foundation elements (12), a base slab (16) sealed off from the groundwater, and a facing wall (18) extending from the base slab (16) up to the roof slab (14). Arranged between the deep-foundation elements (12) and the facing wall (18) is an intermediate space (20) which communicates with the groundwater-bearing earth (10). The facing wall (18) is sealed off and is supported on the base slab (16) and on the roof slab (14) against the groundwater pressure prevailing in the intermediate space (20). The deep-foundation elements (12) are thus relieved of transverse forces from the groundwater pressure and therefore do not need to be dimensioned to be so sturdy as hitherto under the otherwise identical conditions. The facing wall (18) readily withstands the groundwater pressure, since it has to be reinforced anyway for reasons of impact safety. <IMAGE>
