Patent DE-3517567-A1 (DE)
Title: Drive system for appliances and vehicles, especially motor vehicles
Inventor: THOLEN PAUL DIPL ING
IPC: F02B29/04
Filed: 1985-05-15
Abstract: A drive system for vehicles, especially motor vehicles, has a supercharged internal combustion engine (1) and a first coolant circuit (10) for cooling the combustion chambers of the internal combustion engine with a coolant radiator (11) to which air is admitted and a circulating pump (13), together with a second coolant circuit (16) for cooling the supercharged combustion air likewise by means of a coolant radiator (17) to which air is admitted and a circulating pump (18), and a heat exchanger (8) through which the combustion air flows. In order to create an improved drive system of this type, which is as simple as possible to construct and is also suitable for vehicles, which in relation to the total operating time only briefly need charge air cooling, it is proposed that the system according to the invention have an additional storage tank (19) provided in the second coolant circuit (16) and formed by a coolant expansion tank. This additional storage tank (19) may at the same time be designed as a coolant expansion tank of the first coolant circuit (10) and be connected to this first coolant circuit by way of connecting lines (22, 23) equipped with controllable valve devices (24, 25). <IMAGE>
Patent DE-3519140-A1 (DE)
Title: Assembly with fluid through-flow, with pistons reciprocating in cylinders, such as pumps, motors or internal combustion engines
Inventor: EICKMANN KARL
IPC: F01B17/02
Filed: 1985-05-29
Abstract: The advantages and disadvantages of twin piston engines and free piston engines are analysed. In so doing it is found that the free piston engines, owing to the need to brake the kinetic energies of the piston, are technically difficult to control correctly for high frequencies. In addition abrupt pressure and power peaks and troughs also occur. New engines are therefore proposed in which the reciprocating movement of the free piston is controlled. In addition twin engines are revealed, which are easy to control and cheap to manufacture and which function without the conventional valves or with simple valves. As a result even high-revving internal combustion engines are possible which for a low weight are capable of delivering great power to the crank drive or in fluid flows. These new types of engine therefore promise great power for a low weight so that it no longer seems out of the question that in terms of the power-to-weight ratio they might almost equally be used in aircraft. In a mathematical analysis the provisional theoretical bases are created for the design calculations of such engines. <IMAGE>

Patent DE-3522496-A1 (DE)
Title: Equipment for producing gypsum hemihydrate
Inventor: QUANTE HEINRICH
IPC: B01J19/24
Filed: 1985-06-24
Abstract: For the continuous production of gypsum hemihydrate, equipment is used in which the dihydrate to be converted passes, after appropriate preparation in a mixing vessel, into a heatable reactor space of tubular design, where it is heated up by heat exchangers, which are arranged sectionally and can be charged separately, in such a way that the calcination proceeds continuously and reliably. The heat transfer medium brought into indirect contact with the reaction medium in the heat exchangers is passed through a plurality of heat exchangers, it being ensured that a sufficiently heated heat transfer medium is always available for the heat transfer. The tubular reactor space is assembled to give a tube battery, the heat exchangers being associated in each case with the upward-flow or downward-flow tube sections of the tube battery. <IMAGE>
Patent DE-3523964-A1 (DE)
Title: Process for washing filter cakes
Inventor: FINK EUGEN DR RER NAT
IPC: B01D33/60
Filed: 1985-07-04
Abstract: To improve the washing of solid in filter centrifuges, it is proposed to provide a multi-stage, in particular a two-stage, washing, in such a way that in the first stage, as a result of elevated washing medium pressure, solid heaps occurring during the filling process are levelled out and any fine substances depositing on the layer, principally insoluble ones, are floated off. In the second stage, with reduced washing medium pressure and expenditure, and in a considerably reduced time, the required washing effect is then achieved as a result of the then higher permeability of the filter cake. The washing result is thus substantially improved by the invention with regard to washing time and washing medium consumption.

Patent DE-3614384-A1 (DE)
Title: Method for coating substrates in a vacuum chamber
Inventor: BERGMANN ERICH DR
IPC: C23C16/27
Filed: 1986-04-28
Abstract: In the previous methods for the deposition of coatings on surfaces by means of chemical reactions using gases which are introduced into the reaction chamber (Chemical Vapour Deposition, CVD), electric glow discharges and above all high-frequency discharges were used to activate the reactants. According to the invention, it is proposed to maintain a low-voltage arc discharge in the reaction chamber during the coating. Surprisingly, this produces a much greater activation and ionisation and a more uniform coating even on surfaces of complicated shape. <IMAGE>

Title: Process for producing water-impermeable and porous ceramic shaped bodies
Inventor: KIENOW SIGISMUND PROF DR
IPC: C04B33/32
Filed: 1986-10-21
Abstract: The invention relates to a process for producing water-impermeable and porous, ceramic shaped bodies of clays containing blue conite, illite or bentonite and also blue clays, in which shaped and dried green bodies are fired using exothermic processes and until expansion (swelling, bloating) by liberated gases occurs. It has surprisingly been found that in oxidising firing the swelling process proceeds substantially more quickly and gives products with lower bulk densities if, during firing, the shaped and dried green bodies are subjected to a hold time at from 900 to 100@C and after the hold time the temperature is increased to from 1150 to 1180@C under an oxygen-free atmosphere and is maintained for from 5 to 15 minutes. This hold time, which is dependent on the dimensions of the shaped bodies, should be from one to three hours.

Abstract: The luggage compartment of a vehicle with the loading sill lying approximately at the level of the luggage-compartment floor is provided with a closing wall which can be lowered even when the luggage compartment is loaded. In the non-lowered state items which roll, for example, are thus protected against falling out when the luggage-compartment flap is open, and the loading and unloading process continues to profit however from the advantages of a lower loading sill.
Patent DE-3639599-A1 (DE)
Inventor: FRIESS WERNER
IPC: H01R13/527
Filed: 1986-11-20
Abstract: Explosion and flame-proof electrical equipment, that is to say equipment with a housing of the "pressure-proof encapsulation" protection type, must satisfy specific regulations relating to connection to electrical conductors. The regulation applying to plug-in devices is that these must be interlocked such that they can be withdrawn only when they are not live. There are specific conductor inlets for such equipment which already have official approval. However, with a large number of conductors or conductor wires, the individual connection of the conductor wires to the equipment inside the housing is tiresome. The invention produces a plug-connector intermediate part which is attached to the housing and cannot be released until the approved conductor inlet has been released. The intermediate part permits quick connection of electrical equipment of the said type to an electrical conductor. When the conductor inlet is released, the housing is regarded as being open so that the said instructions for plug-in devices do not apply. A normal plug-connector is thus fitted inside the housing, which allows a plurality of types of conductor to be connected quickly.

Title: Frame construction comprising profile rails and crossmember elements connecting these, in particular for constructing a fair stand
Inventor: KUEFFNER REINHOLD
IPC: F16B5/06
Filed: 1987-09-04
Abstract: In the case of a frame construction comprising a plurality of profile rails and rigid crossmember elements connecting these at a predetermined distance, in particular a fair stand or the like, the profile rails comprise a core profile having at least one retaining rail which projects in the form of a ray over the length of the profile rail and, in its end side remote from the profile core, exhibits a bead-shaped widened portion on either side. The crossmember elements exhibit, in each case at a distance from their end side, a through-passage which is complementary to the bead-shaped widened portion of the retaining rails and merges, towards the end side, into a gap corresponding to the thickness of the retaining rails and, on its opposite side, into a clamping slot. Provided in the region of the clamping slot are clamping means which are directed at a predetermined distance from the through-passage, to be precise transversely thereto, and are intended for the positively locking and frictionally locking connection between the retaining rails and the crossmember elements. A stable frame construction can thus be erected without the use of tools. <IMAGE>
