Title: Electronically commutated DC motor
Inventor: SANDER HORST
IPC: H02K29/08
Filed: 1984-06-06
Abstract: An electronically commutated DC motor having a permanent magnet (3) as a rotor, having a stator (5) with a plurality of salient poles (S1 to S6) with motor windings (for example W10, W11), which are driven in a unipolar manner, and having a rotor-position detector (9). In this case, the winding of each salient pole is divided into a first and a second partial winding (for example W10 and W11 respectively) with an opposing winding direction. The first partial windings are distributed continuously in the rotation direction and in a cyclic sequence on three winding groups which are connected in series. The corresponding second partial winding (for example W21) of the adjacent salient pole is included in each group for each first partial winding (for example W10). Thus, pairs of adjacent salient poles can always be activated simultaneously, but with different magnetic polarity, with the aid of the Hall elements (91, 92, 93) of the rotor-position detector. <IMAGE>

Title: Piston ring for four-stroke internal-combustion engine
Inventor: WOJIK KARL DIPL-ING
IPC: F16J9/20
Filed: 1984-11-16
Abstract: A conventional piston ring for the piston of a four-stroke internal-combustion engine is purposely re-machined so that at least in one specific angular area extending on both sides of the ring gap the running surface is partially removed so that a contour partially set back from the normal round form and hence at least one defined lubricating oil passage is produced. The cross sectional area of such a lubricating oil passage produced between the set-back wall surface on the piston ring and the cylinder running surface determines the extent of oil permeability. Indirectly secured against rotation, such a piston ring is held in the ring groove so that the one lubricating oil passage is arranged in the area of the pressure side of the piston.
Patent DE-3443082-A1 (DE)
Title: Neutron gun
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: H05H3/06
Filed: 1984-11-27
Abstract: The process, which is known from the main application on the basis of a formula and the tube geometry, for converting nuclear ions at a negative anode into neutrons has been modified, purely in terms of the description, without the known tube geometry of the main application type having to be modified in consequence. On the contrary, two-piece guns have been shown and interpreted in accordance with the known single-piece guns. The single-piece gun operates, as before, during starting and operation using the known X-ray rear tube as an ionisation aid. However, the two-piece gun uses the X-ray tubes only for starting. In operation, the starting neutron emission is introduced from the starting emission anode into the gas emission chamber of the second tube stage in order to convert neutral gas atoms therein into nuclear ions as a result of first-stage neutrons impacting with gas atoms, in order to accelerate said nuclear ions towards a second anode, in order to generate second-stage neutrons, a high level of quantity amplification and intensity amplification of the neutron emission taking place. In the case of a second double-tube type, the amplifier tube is only a pot filled with media-neutral gas. First-stage neutrons flow through said pot, ionisation occurs as a result of their impact with gas atoms, and it is thus filled with compressed nuclear ions. After starting, the latter are fed back into the first stage and are accelerated to the anode in order to become converted at said anode into neutrons. The first-stage neutrons are emitted to the target, together with the second-stage secondary neutrons, which results in even better amplification levels ... Original abstract incomplete.

Title: Device for inspecting printed-circuit-board layouts
Inventor: SIMON GUNTER
IPC: G06F17/50
Filed: 1985-02-22
Abstract: A check for forbidden or unusual graphics elements is carried out in order to inspect printed-circuit board layouts which are designed by means of an interactive CAD system, from purely graphical viewpoints. For this purpose, the inspection device has a memory with a list of the forbidden or unusual graphics elements, so that defects can be detected by comparison with the designed printed-circuit-board layout on the basis of criteria which are of a purely graphic nature. The memory is equipped in the manner of a library in which different widths, which can be identified mathematically but are invisible in the optical result, are allocated to the conductor tracks depending on the potential of the power supply of the respective conductor track. Furthermore, criteria which are defined in a component data file are stored (for example all the pins of a discrete component must be connected). The novel device allows defects to be identified which affect the correctness of connections which can be graphically identified.

Title: Combustion chamber design in internal combustion engines
Inventor: DUERING JUERGEN
IPC: F02B23/00
Filed: 1985-03-15
Abstract: The existing engine can utilise only about 1/3 of the energy of the gas particles, since the gas particles fly in all directions. Only the velocity components of the particles, which deliver an impulse to the piston in the direction of the piston travel cause an acceleration of the piston. I modify the combustion chamber as in the following drawing. My intention in so doing is to ensure that as many gas particles as possible, which otherwise do not exert any pressure on the piston, are reflected in the direction of the piston. The adiabatic formula may not be applied since the pressures are directional. I anticipate virtually three times the engine power. <IMAGE>

Patent DE-3515725-A1 (DE)
Title: Control lever
Inventor: LASSE WERNER
IPC: G05G5/02
Filed: 1985-05-02
Abstract: A description is given of a control lever for adjusting a Bowden cable, a linkage or the like, the control lever being distinguished by the fact that it cannot be switched from one end position into the other end position all in one go. Built into the housing of the control lever is a stop against which a counter-stop fixed to the control lever strikes when the control lever is displaced, with the result that the actuating movement is initially stopped. The stop can only be overcome by tilting the control lever approximately perpendicularly to its direction of displacement and then tilting it back again. For this purpose, the control lever is mounted in such a way that it can be tilted perpendicularly to its direction of movement counter to spring force and is held in the tilted position by contact with a sliding rail. A slot in the sliding rail at the level of the stop allows this stop to be overcome by virtue of the fact that the control lever falls into the slot.
