Title: Rotating-piston hot-gas engine with continuous combustion
Inventor: OSTERBURG GUENTER
IPC: F01C11/00
Filed: 1982-11-16
Abstract: The aim of the invention is to lower the fuel consumption of engines while simultaneously reducing their environmental impact. The object is to be achieved by means of a rotating-piston engine with uniformly rotating pistons which uses the Joule cycle with heat recovery. Integrated into the rotating-piston hot-gas engine is a compressor machine and an expansion machine. Because the rotating pistons are only acted upon for half a revolution during the expansion of the hot pressurised gases, the thermal loading is lower than in the gas turbine. This advantage in terms of cooling opens up the possibility of using ceramic materials. The invention can also be used as a combined expansion/compression machine, a compressor, an expansion machine, a liquid pressure pump and as a combined unit for many technical installations, e.g. heat pumps, refrigerating machines or superchargers for internal combustion engines.

Title: Energy exchanger system
Inventor: STRELOW HORST
IPC: F24D10/00
Filed: 1982-12-08
Abstract: The energy exchanger stations (25, 40, 41) are provided as heating medium exchangers in the storeys of the users and consumers or terraced houses etc. The stations are equipped with one or more heaters (14) as exchangers. A heat counter or heat-measuring device (5) ensures perfect counting of the energy used. The built-in safety devices such as expansion vessel (20), pressure control valve (21), pump (19), filling device (24), outflow (22) make possible the connection of an energy transfer station (26). The assembly of the exchanger station with a transfer station (Fig. 3) creates a perfect domestic heat centre. The supply of the energy exchanger station with energy takes place via the heat installation with a central heat station, such as heating boiler or distant heat (38) etc. and is conducted via pipes (43) to the exchanger stations. The installation is controlled in the combined exchanger/transfer stations. <IMAGE>
Patent DE-3247408-A1 (DE)
Title: Electric heating cost allocator
Inventor: SCHEER ERICH DIPL ING
IPC: G01K17/08
Filed: 1982-12-22
Abstract: The invention relates to an electric heating cost allocator having a first temperature sensor, which measures a radiator (heater) temperature, and a second temperature sensor, which measures a lower temperature, in particular a temperature of the return (recirculating) air. The heating cost allocator forms the difference between the two measured temperature values and derives therefrom a display value which is proportional to the heat consumption. This heating cost allocator is additionally assigned an electronic control circuit which cooperates with the temperature sensor which measures the lower temperature, in particular return air temperature, in such a way that given a temperature value which occurs at this temperature sensor due to impermissible manipulation and exceeds a maximum permissible temperature, said temperature value disconnects the temperature sensor measuring the lower temperature from the electric heating cost allocator, and instead a simulating network which prescribes the value of the mean temperature at which the room is used is connected to said allocator.

Title: Method and control arrangement for resistance welding
Inventor: DEUBEL REINHARD
IPC: B23K11/25
Filed: 1983-01-14
Abstract: The method and the control arrangement for controlling the electrical work during resistance welding of, preferably, chain links using a welding process which operates with a constant frequency make it possible to supply a precisely defined quantity of energy at a specific time to a welding point, as a result of which uniform and reproducible welded connections are implemented which ensures an increased welding reliability. The object of the invention is to supply a defined quantity of energy corresponding to a desired value to a welding point during each mains half cycle. This is done by switching on the energy supply to the welding point, subject to a preset phase-gating angle, during each mains half cycle which causes the welding, and, once a work integral corresponding to a desired value for the relevant mains half cycle has been reached, being switched off within the same mains half cycle. Turn-off thyristors are preferably used for controlling the electrical work. <IMAGE>

Title: Electronic timer
Inventor: BROMANN PETER
IPC: G04G15/00
Filed: 1983-03-25
Abstract: The present invention relates to an electronic timer which can be used, for example, as a time switch for controlling charging times for electric memories. Such electronic timers generally cannot be read off for the actual state of time. Neither is it possible to set times to prescribable values. In order to dispense with these disadvantages, a voltage divider provided with a time scale is provided which is connected to one input of a comparator of the timer, and the output of a counter is connected to the other input of the comparator via a digital-analog convertor. Connected to the output of the comparator is a switch which connects a frequency divider between a pulse voltage generator and the counter.

Title: Method of producing a plate-shaped construction element, and construction element produced according to the method
IPC: F28F3/12
Filed: 1983-04-15
Abstract: The invention relates to a method of producing a plate-shaped, torsionally rigid and thin-walled construction element, the construction element produced according to the method, and the application of the construction element. The construction element 1 according to the invention is produced in such a way that first of all a one-piece hollow-section body is formed by extrusion from a block of material which can be shaped without cutting, e.g. an aluminium alloy, which hollow-section body consists of two planar plate sections which are parallel to one another and are located at a distance from one another and between which hollow chambers extending over the length of the sectional body are formed by vertical webs arranged at a lateral distance from one another. The hollow-section body is then shortened to the respectively desired length. The open end sections of the hollow-section body are closed. To use the hollow-section body as a surface heat exchanger 2, the end-section-side webs 6 in the hollow-section body 3 can be shortened so that flow-deflection or collecting zones 10, 11 are formed at the end sections 8, 9. Fastened in the area of these flow-deflection or collecting zones 10, 11 are pipe connection pieces 14 which enable the surface heat exchanger 2 to be connected to the pipeline system of the heat transfer medium (Fig. 2). <IMAGE>

Abstract: PCT No. PCT/DE83/00212 Sec. 371 Date Dec. 18, 1984 Sec. 102(e) Date Dec. 18, 1984 PCT Filed Dec. 20, 1983 PCT Pub. No. WO84/04359 PCT Pub. Date Nov. 8, 1984.An apparatus for injecting fuel into the combustion chamber of an internal combustion engine, having an injection nozzle and following the injection nozzle a partition (12, 23, 29) which is provided with through openings (13) for the injection streams and is embodied as a guide device for a partial flow of combustion air, which flow is accelerated by the injector action of the fuel streams in the through openings (13). A device (26, 24, 32) for preheating the partial flow of combustion air is also secured to the partition (12, 23, 29). In this apparatus, the partial flow of combustion air circulates virtually continuously through the partition (12, 23, 29) embodied as a guide device, and the acceleration caused by the injector action of the fuel streams increases with increasing engine rpm. This has the advantage that over the entire power and rpm range of the engine, a uniform course of combustion and a reduction of toxic emissions is attainable.

Title: Process and apparatus for curved continuous casting of metal, especially of steel
Inventor: BROCKHOFF REINER DIPL ING
IPC: B22D11/10
Filed: 1983-09-01
Abstract: Constructional height of the curved continuous casting plant can be saved according to a process for the curved continuous casting of metal, especially of steel, with subsequent bending back of the cast strand cooled in a curved shape by forced cooling, in which the metal melt is introduced into the curved continuous casting mould (7) from a supply container (19) arranged above the curved continuous casting mould (7) and the casting level (12) is regulated, the casting level being considerably under the horizontal through the midpoint of oscillation and the melt under the casting level (12) in the curved continuous casting mould (7) being deflected. Although the constructional height of the continuous casting plant can be reduced only on the basis of a special ladle metallurgy and a special dip casting technique, without a worse degree of purity of the cast structure, and moreover increasing bending-back deformations have to be taken into account, the constructional height of circular arcuate plants and oval curve plants can be reduced if the problem of pouring into the continuous casting mould is simultaneously solved. For this purpose it is proposed that with a curved continuous casting mould (7) lying 10 DEG -30 DEG  under the horizontal, the metal melt is deflected through a dip casting pipe (13,14) into the strand core (15) of the casting space (7d), and is divided with a uniform flow profile over the casting cross section in the casting space (7d). <IMAGE>

Title: DC/DC voltage converter in a bridge circuit
Inventor: LECHLER SIEGFRIED ING GRAD
IPC: H02M3/337
Filed: 1984-01-26
Abstract: A DC/DC voltage convertor in a bridge circuit has storage inductors (L1, L2) in two bridge side arms. The residual energy in these storage inductors after discharging to the load (RL) is supplied back into the input voltage source (UE) by means of a return transformer (RT). The return transformer (RT) is connected to the input voltage source (UE) and to the storage inductors (L1, L2) such that, in the reverse-charging phase, the transformed voltage of the corresponding storage inductor (L1, L2) is in parallel with the input voltage source (UE). This measure allows a very high efficiency of the converter to be achieved (Fig. 2). <IMAGE>

Title: Method of reprocessing spent oils
Inventor: REID LLOYD E
IPC: C10M175/02
Filed: 1984-02-15
Abstract: A method of reprocessing spent oils, in particular spent lubricating oils which are normally regarded as waste and are discarded or burned, is characterised by the following steps:     a) heat treatment of the spent oil, b) if desired, stripping of the heat-treated spent oil under conditions which are sufficient to remove the low-boiling conversion products from the heat treatment,   c) distillation of the heat-treated oil,   d) passing the distillate through a bed of activated material, and e) hydrotreating of the distillate pass through the bed under standard hydrotreating conditions.   If the spent oil subjected to reprocessing contains water and fuel fractions in quantities which, in the view of an expert, are sufficiently large to be able to have an adverse effect, the spent oil is subjected, before the heat treatment, to a stage for removing water and fuel fractions.

Patent DE-3420504-A1 (DE)
IPC: B23Q27/00
Filed: 1984-06-01
Abstract: A conventional lathe-type machine. A spindle (18) with a chuck (20) for the workpiece is secured in a conventional manner on a machine bed (10). Also fixed to the machine bed (10) are two other shafts (52, 56). The drive motor (22) which causes the spindle (18) to rotate, also drives, via a gear change box (36) the two shafts (52, 56). Fixed to one shaft (52), via a radial movement component, is a bearing (60) for a tool-carrier (62). In accordance with the drive system, the latter is connected by means of a radial movement component (78) with the other shaft (56). When the spindle (18) and the two shafts (52, 56) rotate, the tool held on the tool-carrier (62) moves along a closed trajectory, which is the result of the superimposition of the trajectories of the tool carrier (62) and the bearing (60). At the same time, the tool also performs a movement of its own. As a result, the tool is thus obliged to follow a trajectory which, when applied to the also rotating workpiece, causes the part to be cut so that it has not a circular shape, as in the case of a conventional lathe, but a shape which is polygonal. It is possible to produce, for example, rectangular parts. The special feature of this system is that the masses which are moved eccentrically are small. Only the tool-carrier (62) and the tool are moved eccentrically.
Patent DE-3422054-A1 (DE)
Title: Method for quantitative and/or qualitative detection of particles suspended in gases
Inventor: BURTSCHER HEINZ
IPC: G01N27/00
Filed: 1984-06-14
Abstract: The present method permits the qualitative and/or quantitative detection of suspended particles present in a gaseous carrier. To this end, the aerosol is heated, for example in a thermal diffusion separator. In the process, the suspended particles are brought to an elevated temperature, and substances are evaporated from the particle surface according to their volatility and bound to the wall of the thermal diffusion separator. This is followed by measuring the photoelectron emission from suspended particles which had earlier been flowing through the thermal diffusion separator. The dependence of the photoemission on the temperature of the thermal diffusion separator can be registered in a photothermogram and characterises the suspended particles. In an extension of the method, substances evaporated from the suspended particles, after enrichment on the wall of the thermal diffusion separator, are released again by heating and adsorbed on a scavenger aerosol of which the photoemission is then measured. The extended method enables quantitative determination of the suspended particle fractions associated with defined temperatures of the thermal diffusion separator.
