Patent DE-3032656-A1 (DE)
Title: Petrol drive IC-engine - has combination of injection timing and supercharging to give compression ignition with high torque
Inventor: HIEMER WILLIBALD
IPC: F02B3/06
Filed: 1980-08-29
Abstract: The engine has four cylinders (2) in line with a piston (7) reciprocating in each. There is a separate supercharger (10) for each cylinder delivering air directly into the cylinder. The supercharger has a rotor (14) eccentric in a cylinder (11). The crescent shaped space (13) between them is sealed by a radial vane (19) sliding in the cylinder. Fuel is injected (53) into each engine cylinder and injection begins at least 25 degrees after top dead centre. The fuel used is petrol but the combination of high supercharging and injection timing results in operation as compression ignition. The timing of the combustion also gives a high torque.

Title: Salient pole electric machine coil winding head fixture method - uses field coils wound through insulation material cavities during winding of stator laminations
Inventor: GOLDBERG DIETRICH DIPL ING
IPC: H02K3/52
Filed: 1980-10-04
Abstract: The salient pole electric machine fixture method for the field coils winding head is designed to improve the cooling of the active parts of the motor partic in the region of the coil winding head and to stop parts of the insulation material (e.g. thermo- or duroplastic) dropping down into the airgap between the armature and pole faces as a result of relatively high temperatures leading to melting of the insulation. The field coils, during winding of the stator laminations stack, are wound through the cavities formed by the insulation material collars solely for preliminary fixture of the coil winding head. The collars are separated after curing the impregnating material for the end sections winding.

Patent DE-3049558-A1 (DE)
Inventor: STOEHR HELMUT DIPL CHEM DR
IPC: A01G25/06
Filed: 1980-12-31
Abstract: System for the artificial underground irrigation or watering of soil, with flexible tubing of a porous material, characterized by tubes with a non-expanded porous inside structure. The tubes are obtained through extrusion of a homogeneous mixture of at least two components, one component a meltable polymer and the other component a liquid inert in relation to the polymer. Both components forming a binary system displaying in liquid aggregate state a range of complete miscibility and a range with a miscibility gap. Preferred parameters include an inside tubing wall surface with open pores and an outer wall surface, the degree of openings of which, calculated as fraction of open area, is reduced at least 20% in relation to the inside wall surface; open pores in the outer wall surface for the most part of a pore diameter of less than 4  mu m; tubes with a pore cavity volume of from 50-90%; tubes made of polypropylene; tubes made of glass fiber-reinforced polypropylene; tubing wall thickness of about 0.5 to 2.5 mm and outer diameter of about 2.5 to 25 mm. The tubing may be disposed within tubular-shaped sheaths of a matted web, composed of a plurality of fibers melt-spun from synthetic polymer, crossing over in places and fused together at the places of crossing. The sheaths may have a longitudinal grooved contour, and the matted web may be composed of polycaprolactam fibers with a diameter of about 0.2 to 1.5 mm. Couplings composed of the same material as the sheaths may be disposed at intersections thereof. The system is useful for the irrigation of grass, for irrigation in several layers, for permanent irrigation in arid zones, for the distribution of fertilizer, herbicides and/or pest control agents.
Patent DE-3106287-A1 (DE)
Title: Process and device for the air-conditioning of rooms
Inventor: ADAM JAKOB
IPC: F24F13/06
Filed: 1981-02-20
Abstract: Where there is a low air requirement in a room to be air-conditioned, a small amount of air per unit of time (basic flow) is continuously blown out at a relatively high flow rate, e.g. through nozzles (3). Where there is a higher air requirement, a large amount of air per unit of time (main flow) is blown out, e.g. via a slotted-nozzle arrangement (4). When the main flow is started, the basic flow is stopped and when the main flow is switched off, the basic flow is switched on. Where there is a high air requirement, the main flow is blown out continuously and its strength altered as required. Where there is an average air requirement, the main flow is blown out intermittently. This process has the advantage that, in a very large regulating range, good flushing of the room, which is to be air-conditioned, with fresh air is achieved. <IMAGE>

Title: Device for drilling machines for collecting the drillings accumulating during drilling or percussion drilling
Inventor: GEIS WILHELM ING GRAD
IPC: B25F5/02
Filed: 1981-04-03
Abstract: A device for drilling machines for collecting the drillings accumulating during drilling or percussion drilling, which consists of a receptacle which can be pushed together telescopically against spring force, is guided parallel to the tool and has a through hole for the drilling tool, is improved to the effect that a largely unobstructed view of the drilling location is guaranteed, and an additional extraction fan can be dispensed with. This improvement has been achieved by the receptacle being designed as a guide sleeve extending in the axial direction of the drilling tool and partly enclosing the drilling tool and adapted to its diameter. One end of a dust container designed as spring bellows is guided in a rotatable and longitudinally displaceable manner on the outer surface of the guide sleeve. The other end of the dust container is united by a force closure with the chuck for the drilling tool. <IMAGE>

Title: Device for applying lubricants
Inventor: MENZEL GUENTHER DR ING
IPC: F16N9/00
Filed: 1981-05-06
Abstract: Precision-engineering components, e.g. dials, have to be lubricated at various points which are subjected to mechanical loading. Lubrication is carried out, in the case of the prior art of the production apparatuses, by pressing devices, drip-feed lubricators or wick oilers or by dipping complete parts into a solution of the oil or a suspension. According to the invention, the lubricants are applied in a film-like manner by means of spraying on once or a number of times using a printing mechanism, known per se, of an ink-jet printer which can move in the x-direction and y-direction and, if required, also in the z-direction.

Patent DE-3136276-A1 (DE)
Title: Arrangement for achieving a constant output voltage
Inventor: FLEISSNER ANTON
IPC: G05F1/13
Filed: 1981-09-12
Abstract: For devices and systems where, in particular, alternating voltages having correspondingly low tolerances are needed and a sinusoidal or other curve shape, particularly a square wave, is optionally of advantage. The solution is achieved by means of a generally known multi-core-type magnetic regulator consisting of a basic unit with series reactor and parallel reactor. The function is generally known. An essential feature in this regulator is the possibility of achieving the desired curve shape by adding filters or capacitors. As is shown in the attached drawing, this switching-over is simply effected by connecting a constructional unit which contains the corresponding filters or the desired capacitor. <IMAGE>

Title: System incorporating a Hall effect device
Inventor: WILSON BRETT
IPC: G01R15/00
Filed: 1982-05-08
Abstract: In the novel system incorporating a Hall effect device (1), compensation is made for the temperature-dependent offset voltage, which is due to the offsetting of the output connections with respect to the equipotentials in the device, by regulating the output as a function of a signal typical of the impedance presented by the device for the biassing current supplied by the constant current source (3) to the device (1). The regulating signal is a signal which is typical of the voltage drop generated transversely across the device by the biassing current. <IMAGE>
