Patent DE-3722009-A1 (DE)
Title: Electromagnetically actuatable 3/2-way valve
Inventor: SCHIEL LOTHAR
IPC: F16K31/10
Filed: 1987-07-03
Abstract: An electromagnetically actuatable 3/2-way valve for selectively connecting an output connection to a first or a second input connection is proposed, the connection being effected via a valve chamber to which the output connection is directly connected and to which the input connections are each connected via a sealing seat which can be shut off or opened by means of a movable valve closing member. The valve also has at least one electromagnet, the housing of which contains a magnet winding as well as a displaceable armature which, upon excitation of the electromagnet, actuates the valve closing member via a valve actuating plunger, a connection being made between the second input connection and the output connection when this valve closing member is in the inoperative position. In order to prevent a temporary lack of vacuum tightness during changeover (connection of all three connections), the invention provides that the valve closing member be formed by a flexible valve member (9) having a sealing face (27) which, when in the inoperative position, is prestressed in the direction of the first sealing seat (16) by means of a compression spring (21), the valve member (9) being provided during actuation with an intermediate position in which the two sealing seats (16, 17) are closed simultaneously. <IMAGE>

Title: Method for transmitting signals in the microwave band, especially the millimetric waveband, and an arrangement for carrying out the method
Inventor: MENZEL WOLFGANG DR ING
IPC: H04B7/005
Filed: 1987-09-10
Abstract: The method relates to the transmission of (multiplex) signals in the microwave/millimetric waveband. In order to minimise frequency/phase shifts between the transmitter and receiver, a reference signal which is produced at the transmitter end is transmitted via a separate channel. At the receiver end, the reference signal is compared with an identical reference signal produced at the receiver end. A correction signal for automatic tuning of the receiver is derived from the frequency discrepancy.

Title: Lamellar locking differential for motor vehicles, in particular front wheel drive passenger cars
Inventor: GEES THEODOR
IPC: F16H48/30
Filed: 1987-11-11
Abstract: A lamellar locking differential for motor vehicles, in particular front wheel drive passenger cars, has inner and outer lamellas in order to limit the differential slip in an actuatable and deactuatable fashion, the said lamellas being connected to one another in a frictionally engaging rotational manner as a result of axial spring loading and the inner lamella being connected fixed in terms of rotation to one of the drive shafts and the outer lamellas being connected to the differential housing (so-called cage). A coupling device is provided which serves to produce or release the rotational connection between drive shaft and inner lamellas. As a result, an actuatable and deactuatable slip limiter for differential transmissions is provided, which limiter is particularly suitable for vehicles with front wheel drive. The switching process which takes place as required can be carried out manually or automatically.

Title: Safety belt system in motor vehicles
IPC: B60R22/46
Filed: 1987-11-20
Abstract: The invention relates to a safety belt system in motor vehicles to make it possible to reduce a preliminary displacement of fastened-in vehicle occupants in the event of an accident. To achieve this, a belt tightening device (23) is provided to eliminate existing belt slack and a clamping device (4) is provided for the belt (3). To ensure that the belt (3) can be passed through the clamping device (4) without contact during normal use of the safety belt system and that there is troublefree interaction with the belt tightening device (23) when the clamping device (4) is operating, provision is made for transmission means to be connected to the belt tightening device (23) which are coupled to the clamping device (4), preferably take the form of a Bowden cable (18) and, when the belt tightening device (23) becomes active, act on the clamping device (4) in a manner which cancels out the operation of the clamping jaws position-fixing element (16), in order to bring the clamping jaws (5, 6) of the said clamping device (4) into contact with the belt (3). This ensures that the clamping device (4) can be directly activated by the belt tightening device (23) when the latter becomes active, without initiating the actual belt clamping operation, while permitting the design to remain simple. The actual belt clamping operation only occurs in the event of appropriate movement of the belt (3) owing to preliminary displacement of the fastened-in vehicle occupant (Fig. 1). <IMAGE>

Title: Method and device for mounting new soles and heels to worn shoes
Inventor: LABUS PETER DR
IPC: A43D5/00
Filed: 1988-01-27
Abstract: New soles or heels have previously been mounted on worn shoes in such a manner that, by steps, first the old remaining sole or the old remaining heel is removed, sometimes by hand. Then an already pre-punched sole or heel, which is approximately one or two numbers bigger, is mounted on the thus prepared sole or heel surface. The projecting parts are adapted, by hand, flush to the old shoe in such a manner that they are either cut or milled off. The new method or the new device make possible working both in pairs and extensively automatically. The removal of a part of the surface of the old sole or the old heel is carried out in pairs by a removal device which is adjusted in advance and then works without further operation. The making of the new flush sole or of the new flush heel takes place by means of a scanning device on the pair of old shoes, coupled to a copying miller which mills the new sole or heel out of raw material. New soles or heels are thus mounted on worn shoes.
Patent DE-3816879-A1 (DE)
Title: Vehicle platform
Inventor: DRAEYER RUDOLF
IPC: B62D33/02
Filed: 1988-05-18
Abstract: The vehicle platform has at least two aluminium supports (1, 2) running in the longitudinal direction of the vehicle and a multiplicity of profiled aluminium rods (3) which are arranged in the transverse direction of the vehicle, are connected fixedly to one another and to the supports, serve as platform planks and form the supporting surface. At those points at which the rods (3) rest on the supports (1, 2), they are bonded to them, this glued joint forming the only attachment between the profiled rods and the supports. As a result, it is possible rapidly and reliably to assemble a platform without any subsequent work being necessary. A further advantage which should not be underestimated consists in that the defective aluminium platform can be melted down without parts made of foreign material having to be removed beforehand. <IMAGE>

Patent DE-3823247-A1 (DE)
Inventor: SCHELLE AXEL DIPL ING DR
IPC: B61G7/00
Filed: 1988-07-08
Abstract: The automatically coupling coupler for rail vehicles having side buffers has at the side of the coupling heads 5,5' in each case one auxiliary coupler, the pulling elements 9,9' of which are already couplable if the coupling heads 5,5' are still at a distance from one another. As a result, a coupling of the pulling force transmission by rail vehicles standing in a track curve is possible if only their side buffers 1,1' on the inside of the curve are touching and the coupling heads 5,5' having in each case one coupling plane 6,6' lying in the buffer plane 3,3' are still at a distance from one another. After being moved into a straight track section, the coupling heads 5,5' can be pressed together for coupling. The auxiliary couplers can be constructed to couple and also uncouple automatically. <IMAGE>

Title: Subtractor circuit for serial subtraction of BCD 8421-coded decimal numbers
Inventor: MERKLE PAUL
IPC: G06F7/50
Filed: 1988-08-06
Abstract: The serial subtractor circuit according to the subject of the invention has two dual full subtractors (1 and 2), of which the dual full subtractor (2) is used for a possible correction subtraction of the number 6 (LHHL). The subtraction of one BCD 8421-coded decimal digit from another BCD 8421-coded decimal digit takes place in eight shift register cycles, of which the fifth cycle overlaps in time with the next first cycle, and the eighth cycle overlaps in time with the next fourth cycle. Thus, for each subtraction, four starting shift register cycles are required. After four cycles, the intermediate result number is stored in the shift register (6). If the result is less than the number 0 (LLLL), the correction number 6 (LHHL) is subtracted in the sixth and seventh cycles. In these two cycles, there is high potential at input G. <IMAGE>
Patent DE-3828977-A1 (DE)
Title: Composition and method for removing deposits, encrustations and the like
Inventor: HOEHN THEO
IPC: C09K8/528
Filed: 1988-08-26
Abstract: The invention relates to a composition and a method for removing deposits, encrustations and the like, such as iron- and manganese-containing deposits, in drinking water supply units and the like, using an aqueous solution of an acidic component containing chlorine compounds, and an oxidising component. To achieve disinfection simultaneously with cleaning, it is provided that the oxidising component contains peroxomonosulphate compounds. This results in active chlorine, which acts as disinfectant, being formed from the acidic component by oxidation of chloride ions. The disinfectant action is moreover generated precisely where the deposits, encrustations, for example those containing iron, are being detached and dissolved by means of the acidic component, that is to say exactly at the sites to be disinfected. The oxidising component preferably contains perborate compounds, and the acidic component preferably contains hydrochloric acid.
Patent DE-3829515-A1 (DE)
Title: Method for treating the surfaces of workpieces in aqueous liquids
Inventor: WINKLER LOTHAR DR
IPC: B05D3/14
Filed: 1988-08-31
Abstract: In the treatment of the surfaces of workpieces in aqueous liquids, in particular aqueous solutions and wash waters, the water underlying the treatment liquids is activated in a magnetic field prior to the treatment. This leads to a considerable reduction of the drag-out losses with constant cycle times in the case of an automated electroplating apparatus or to a reduction of the cycle times with constant drag-out. The consequences are noticable saving of chemicals, water and waste water and reduction of the waste water pollution.

Title: Use of organo-mineral products for consolidating and/or sealing formations which are exposed to increased high-energy radiation
Inventor: HILTERHAUS KARL-HEINZ
IPC: G21F9/30
Filed: 1988-09-16
Abstract: Geological and/or artificial formations, in which radioactive material is to be stored, for example underground or above-ground final or temporary storage places, must meet, for safety reasons, more stringent demands with respect to reliability, permanence and tightness. By means of a consolidation and/or sealing with the aid of organo-mineral products known per se, in particular using organo-mineral products which are formed by reacting organic polyisocyanates with epoxide resin(s) in the presence of aqueous alkali metal silicate solutions, outstanding consolidation can be achieved which is not significantly impaired by the radioactive emission. The use of solid organo-mineral products not having a foam structure also ensures the demanded gas tightness and water tightness. Consolidation and/or sealing of final or temporary storage places for radioactive material, civil engineering structures of nuclear power stations, transport vessels for radioactive material or decay pits and water containers, in which radioactive material is stored.
Patent DE-3831671-A1 (DE)
Title: Water-resistant gypsum or gypsum cement
Inventor: WETHMAR HERBERT
IPC: C04B11/05
Filed: 1988-09-17
Abstract: Water-resistant gypsum or gypsum cement is produced from milled smelter byproducts slag lime, slag sand or slags from steelworks and gypsum from flue-gas desulphurisation plants or other chemical gypsums or natural gypsums together at temperatures between 150@C and 1500@C in appropriate equipment. In the low temperature range, the smelter products are activated by the gypsum so that setting reactions occur on addition of water, as a result of the calcium silicate or calcium aluminate content. From 200@C to 700@C, the FGD gypsum is converted into hemihydrate (CaSO4.1/2H2O) or anhydrite (CaSO4), with the smelter byproducts being activated and, after quenching and milling, solidifying on addition of water. Between 1300@C and 1500@C, a slag-sulphate melt containing -Ca2SiO4, Ca3Al6 O12.CaSO4 and anhydrite is formed, which are, after quenching and milling, the base components of the hydraulically reacting product. The product after setting consists mostly of the minerals portlandite Ca(OH)2, hydrogranate Ca6 Si2 O8(OH)4, ettringite Ca6 Al2(SO4)3(OH)12.26H2O, thaumisite Ca6Si(SO4)2(CO3 )2(OH)12. 24(H2O), spurrite Ca5(SiO4)2CO3 and Ca3Al6O12.CaSO4. It has high compressive and flexural strengths which increase over long periods of time. The product is well suited for fixing heavy metals and is thus particularly useful in the field of environmental protection.

Title: New type of car seats for passenger vehicles (multiphase seat cushion) - storage systems - car first-aid case and the like
Inventor: KRIPP HERBERT
IPC: B60R7/04
Filed: 1988-10-07
Abstract: The further development of the invention includes the entire group of seats for passenger vehicles for the integration of storage systems for a car first-aid case etc. New discoveries supported by the further, novel design due to safety, such as the fitting of the car first-aid case required and resulted in new possibilities for integrated storage systems in one of the two front seats, their backrest parts and also in the rear group of seats in the passenger vehicle. Moreover, the user can now and in future store in a theft-proof manner, and even lock for example attaché cases etc. in the vehicle itself, in one of the seat storage systems, in a manner such that it cannot be seen by people on the outside and does not cause an obstruction. Furthermore, this novel storage means for the car first-aid case in the vehicle interior in a clearly integrated manner results in more safety than ever before since in the event of an emergency help can already be obtained from the inside.
Patent DE-3840551-A1 (DE)
Title: Method and arrangement for improving the reproduction of sound events by loudspeakers
Inventor: KRAUSS GUENTER J
IPC: H04R3/04
Filed: 1988-12-01
Abstract: Loudspeakers, particularly bass reflex enclosures, only provide for a reproduction of sound events which is in most cases perceived to be "flat" in the bass region and which inadequately matches the sense of hearing. It is proposed to compensate for a first conjugate complex pole pair located in the region of the lower cut-off frequency of the loudspeaker enclosure and to replace it with a second pole pair which is at a lower frequency than the first pole pair. This surprisingly results in an improved bass reproduction, particularly in an improved reproduction of "pulse-shaped" sound events.

Patent DE-3913472-A1 (DE)
IPC: A61L2/04
Filed: 1989-04-24
Abstract: Described is a process for the thermal sterilization of toxic medical waste using steam, in which the waste is brought, in an atmosphere with a reduced oxygen content, in direct contact with steam. The process is preferably carried out in the presence of ozone. The process is conviently carried out in a device comprising a chamber (17) fitted with a vapour exit pipe (6) and equipped with a microwave heating system (21) for heating the interior (22) of the chamber. The microwave heating system (21) is integral with the floor and walls of the chamber (17), and passing through the floor are supply lines (1) for an inert gas to reduce the oxygen concentration inside the chamber (17). The lid (23) of the chamber is double-walled and fitted with inlet and outlet lines (24) for a coolant, e.g. nitrogen. Disposed inside the chamber is a waste container (18) which holds the medical waste to be sterilized. Passing through a central opening in the lid of the waste container (18) is a retractable nozzle (19) which contains several delivery lines for an ozone-containing gas, water or an aqueous solution of ozone and/or an inert coolant such as nitrogen. The medical-waste disposal system of the invention is simple, inexpensive, reliable and rapidly operated, and results in virtually complete sterilization without producing any pollutants.
