Patent DE-3321149-A1 (DE)
Title: Combustion chamber, especially for nozzle burner
Inventor: LOEFFLER HANS DIPL ING
IPC: B32B18/00
Filed: 1983-06-11
Abstract: The chamber consists of an outer metal casing and an inner lining of a refractory ceramic material which delimits the combustion space, with an intermediate layer of high temperature-resistant fibres, preferably carbon fibres, arranged between these for the compensation of the different expansion coefficients of the metal casing and the lining, and also for the production of mass contact between these. The production of such a combustion chamber takes place such that a mat-like or fabric-like mass of the high temperature-resistant fibres also adhers to the inside of the metal casing, which acts as part of a ramming mould, and the ceramic mass is then rammed in in a doughy or pasty state and is hardened, penetrating at least on the inner side into the open structure of the mat.

Title: Evaporator regulation in sorption heat pumps
Inventor: NENNING PETER DR ING
IPC: F25B15/02
Filed: 1983-06-22
Abstract: If fixed throttles are used, in sorption heat pumps for household heating, as the expansion valve for the refrigerant upstream of the evaporator, operating states can arise in which, e.g., with a rise in the temperature of the secondary heat source for the evaporator, or with a fall in the temperature, e.g., of the hot water (= cooling water for the absorber), the absorber exerts such suction that the refrigerant in the evaporator evaporates at excessively low temperatures, and consequently only a portion of the evaporator is effective. As a remedy, a storage vessel for refrigerant is arranged geodetically below the evaporator and discharges into the solution circuit of the absorber via a valve with a relatively large opening when the temperature difference of the refrigerant between its inlet and outlet at the evaporator becomes too large. The equilibrium state in the solution circuit can thus quickly adapt to the respective operating states in such cases.
Patent DE-3323210-A1 (DE)
Title: Procedure for transporting gases or liquids, and device for its implementation
Inventor: LAUFENBERG JOSEF
IPC: F03B17/02
Filed: 1983-06-28
Abstract: At least a first system cycle, which performs work and which is operated with pressurised gas, and at least a second system cycle, which operates with liquid, are coupled with one another. This improves the efficiency of the extracted work which is to be given off, and at the same time optimum use is made of the buoyancy forces inherent in the liquid medium. The operating stages in system cycles are affected by freefall and buoyancy, and these are made use of advantageously, even at small pressure differences, in the transition of a compressed gas into its expanded state, and as a result more external work is extracted. At the same time, heat is accepted in a system cycle at a low temperature and, by selecting a particular material (not a fuel), energy is given off. The system cycles are coupled with regard to heat supply and heat removal, and energy supply and energy removal. The necessary heat balance can be achieved at a low temperature via environmental heat (soil).

Patent DE-3329968-A1 (DE)
Title: Storing device for essentially bar-shaped or billet-shaped workpieces
Inventor: MERKLE ROLAND
IPC: B23Q7/10
Filed: 1983-08-19
Abstract: The invention relates to a storing device for essentially bar-shaped or billet-shaped workpieces. Via a chute and a separating device attached to its end, rows of workpieces are separated thereon and discharged in succession into a corresponding magazine which is provided with parallel filling shafts. The magazine is moved further in timed sequence transversely to the chute and the separating device in accordance with the filling. The separating device itself is essentially determined by two locking devices which can be actuated alternately and are at a defined distance apart, in which arrangement the blocking devices can be activated by corresponding non-contacting sensors. Such a storing device can be used in particular in the centreless grinding of round workpieces of different length and diameter. By systematic deposit of the workpieces in transport magazines, these workpieces and their sensitive surfaces are protected from damage. Mechanical storing is substantially quicker than would be possible manually, so that the capacity of the machine tools arranged upstream can be fully utilised.
Patent DE-3332742-A1 (DE)
Title: Portable refuse container
Inventor: NOEPPERT HEINZ
IPC: B65F1/12
Filed: 1983-09-10
Abstract: In a portable refuse container which can be used both as a domestic inside refuse bin and a domestic outside refuse bin, a plurality of chutes are constructed which are continuous from top to bottom and which each have a closable opening at the bottom. These can be jointly closed by pushing onto the floor and jointly opened by a central unlocking device, whereupon the individual types of refuse fall directly into the appropriately designed chutes of a refuse transporter or a refuse processing plant. In any case, sorting of the refuse is no longer necessary; in the second case, only more conventional lorries will be required, instead of expensive refuse transporters.
Patent DE-3333908-A1 (DE)
Title: Air-cooled condenser
Inventor: UMBACH MANFRED
IPC: F25B39/04
Filed: 1983-09-20
Abstract: The invention relates to an air-cooled condenser for several refrigerating plants with both high and low running times, a distributor pipe being provided for each refrigerating plant. Several pipe coils extend from the said distributor pipe, with pipe coil loops, arranged essentially perpendicularly to the air flow direction, extending to a header, and with a fan device for the production of the air flow. In order to considerably reduce the energy consumption, the power of the fan device is designed for the condenser sections for the refrigerating plants with high running time, which are mutually adjacent, the condenser sections for the refrigerating plants with low running time being allotted to the length of the condenser sections for the refrigerating plants with low running time, and the distributor pipes and headers being arranged one behind the other respectively in two rows, one for the refrigerating plants with low running time and one for those with high running time, while the pipe coil loops of the condenser sections for the refrigerating plants with low running time are arranged behind, in the flow direction, the pipe coil loops of the condenser sections for the refrigerating plants with high running time.
Patent DE-3340279-A1 (DE)
Title: Device for splicing the following end of a first plastics film to the leading end of a second plastics film
Inventor: PROTTENGEIER MANFRED ING GRAD
IPC: B65H19/18
Filed: 1983-11-08
Abstract: For the automated splicing of the following end of a first plastics film taken off from a roll to the leading end of a second plastics film taken off from a further roll, the webs of the two plastics films are guided towards one another in a V-shaped manner and the leading end of the second plastics film is guided counter to the movement direction of the first plastics film to a pressure bar and fixed there, which pressure bar can be introduced from the free end into the V-shaped space. A welding bar, which can be moved towards the pressure bar, but is retracted in its resting position, is disposed beyond the V-shaped leg which is defined by the first plastics film. A diameter-sensing device on the working roll switches on the heating for the welding bar when the diameter of this working roll is sufficiently reduced. A recognition device for the end of the first plastics film then causes the welding bar to advance and the two plastics films to press jointly against the pressure bar, which can simultaneously undertake the cutting off of the film residues no longer required. After completed welding the pressure bar can be moved out of the V-shaped space, upon which the reloaded film roll can be pushed in a manner known per se into the position of the preceding roll.

Title: Offset multiple-strand bar for an electrical rotating machine
Inventor: SAITOH TOSHIO
IPC: H02K3/14
Filed: 1984-01-25
Abstract: A bar or conductor which is formed from a large number of strands is located in a slot and extends out of the opposite ends of the slot. Each of the strands is essentially symmetrical and inclined with respect to a vertical axis of symmetry and is offset in the vicinity of the central part, in the longitudinal direction, of the bar part inside the slot. Each of the strands is offset such that the respective strand arrangements are reversed with respect to one another at the opposite ends of the bar end parts outside the slot, the total number of the offset parts of all the strands being less than three times the number of strands. The bar which is arranged in this manner can easily be used in the case in which the number of strands is large, it being possible adequately to prevent local overheating in the bar.

Title: Method for monitoring microprocessor systems and stored-program controls
Inventor: GREWE REINHOLD ING GRAD
IPC: G06F11/30
Filed: 1985-01-25
Abstract: In this method, a control unit (1) is directly connected to the system bus of the microprocessor system (20) or of the stored-program control. The control unit compares checkpoints inserted in the safety-relevant area in the program paths with a stored map and outputs an error signal in the case of deviations. The control-unit (1) hardware construction differs from that of the central processing unit, which also operates with a different program. The checkpoints are determined by coordinates or other numbering and must be accurately defined by the control unit (1) by means of following information:   a) identification of all checkpoints which follow the current checkpoint; b) the maximum time which may elapse until the next checkpoint is reached.   The control unit compares this identification with the stored permissible identification and responds in the case of deviations. <IMAGE>
