Patent DE-3401524-A1 (DE)
Title: Energy-saving and environmentally friendly heating method
Inventor: JOHN GUSTAV
IPC: F24D15/00
Filed: 1984-01-18
Abstract: The method is for the recovery of heat, preferably for heating purposes. No combustion process is necessary. Not heat, but work, is supplied to atmospheric air or another gas. Such a nearly adiabatic compression brings the air to both a higher pressure and a higher temperature. The increase in temperature serves for heat recovery. The pressure increase is utilised by a polytropic or approximately isothermal expansion machine. It recovers a large portion of the initially invested compression energy. Additional mechanical work can be recovered from a heat engine which diverts and converts a portion of the compression heat per se. In the most favourable embodiment of the machine system, the work to be used (compressor) is approximately equal to the recovered work (expansion machine and heat engine), so that the desired heat emerges from the process almost cost-free.
Patent DE-3402010-A1 (DE)
Title: Working appliance to be operated by hand
Inventor: MOECKEL GUSTAV
IPC: B25D17/02
Filed: 1984-01-21
Abstract: The invention relates to a working appliance to be operated by hand, which is intended to make the laborious work of removing rust from iron plates and other iron structures substantially easier. Rust is removed by means of some small hammers which are guided in parallel and which knock against the surface from which rust is to be removed. The small hammers are driven by means of an electric motor which is either integrated into the working appliance or else is located in another working appliance, for example an electric hand drill, to which the appliance containing the small hammers is fastened. The working appliance expediently contains a motor-driven control roller which periodically alternately displaces the small hammers or respective guide rods connected to them, counter to the force of a spring, but then releases them, so that the small hammers are pushed by the force of this spring against the surface from which rust is to be removed.

Title: X-ray intensifying screen
Inventor: DEGENHARDT HEINZ DR RER NAT
IPC: G03C5/17
Filed: 1984-01-25
Abstract: The invention relates to X-ray intensifying screens (1), in particular those for the cassette technique. Good displaceability of the film on the intensifying screen is important in this case, in order to avoid troublesome blocking of the film transport. According to the invention, this is achieved by applying a layer provided with interruptions, for example a protective layer (6) having thickened portions (7), to the wear-stressed surface of the intensifying screen (1). An intensifying screen provided with such a relief surface can be used in X-ray diagnostics, in particular for the cassette technique. <IMAGE>

Title: Light-shaft elements in the modular construction system as attachments/facing for concrete light shafts which have already been installed
Inventor: ROPETER HORST
IPC: E04F17/06
Filed: 1984-11-03
Abstract: In order to embellish the appearance of a concrete or masonry light shaft which has already been installed and which is very often present in basement flats, the installation of the abovementioned light-shaft elements is necessary. Precise fitting into the light shaft which is already present is achieved by simply cutting to size the right-hand or upper sides of the elements - left-hand, right-hand or central part. The elements can then simply be fitted together. Installation is carried out by inserting the cut points into the groove edges, provided in each case for this purpose, of the element which has already been attached on the right or by fitting on the upper end plates. The upper end plates can be made into the necessary adapted shape by cutting the left-hand or right-hand side to size. The base part is inserted after having been correspondingly cut to size, this being possible on all four sides.

Title: Control circuit for a stepping motor
Inventor: KREPPEL CHRISTIAN DIPL ING
IPC: H02P8/04
Filed: 1984-11-13
Abstract: The control circuit for a stepping motor comprises a step-driver circuit (21) which varies the rotating-field phase angle of the stepping motor (1) for each clock pulse of a sequence of clock pulses (at 3) by a predetermined angular step in the desired direction. A rotary pulse transmitter (13), which is driven by the stepping motor (1), produces a feedback pulse for each angular step of the stepping motor (1). A control pulse generator produces a sequence of control pulses at a repetition frequency which is greater than the maximum step repetition frequency of the stepping motor (1). The step-driver circuit (21) varies the rotating-field phase angle by a predetermined angular step in the desired direction for each control pulse of the control pulse generator (19). A first difference-counting circuit (11), which counts the clock pulses and feedback pulses, stores the numerical difference between the number of clock pulses and the number of feedback pulses. A second difference-counting circuit (27), which counts the control pulses and the feedback pulses, stores the numerical difference between the number of control pulses and the number of feedback pulses. The sequence of control pulses can be supplied to the step-driver circuit (21) in the desired direction only until the numerical difference which is stored in the first difference-counting circuit (11) deviates from zero and the magnitude of the numerical difference which is stored in the second difference-counting circuit (27) is less than a predetermined number. If this numerical difference is greater or ... Original abstract incomplete. <IMAGE>

Title: Process and equipment for carburising a steel workpiece
Inventor: SCHWING EWALD
IPC: C21D1/53
Filed: 1985-03-04
Abstract: In a process for carburising a workpiece of steel, in particular case-hardening steel, the workpiece is introduced into a carburising furnace and, in the latter into a carburising gas atmosphere of controllable C level and predetermined composition, carbon black limit and temperature. In the carburising gas atmosphere, a carburisation layer of a carbon content, which decreases from an actual edge value predetermined for the carburisation treatment towards the core of the workpiece, is produced thereon. The actual edge value is then adjusted in a diffusion treatment at diffusion temperature and by diffusion in an inert gas atmosphere to an edge set value predetermined for the workpiece. The workpiece is then introduced into a fluidised-bed furnace, whose fluidised bed is held by the carburising gas atmosphere in a thermodynamic state above the carbon black limit. After the carburisation up to the actual edge value, the carburising gas atmosphere of the fluidised-bed furnace is exchanged for the inert gas atmosphere. During the diffusion treatment, the fluidised bed is held in the fluidised state by the inert gas atmosphere. The diffusion treatment of the workpiece is also carried out in the fluidised-bed furnace.
