Patent DE-3240826-A1 (DE)
Title: DC commutator machine
Inventor: SCHMIDER FRITZ
IPC: H02K25/00
Filed: 1982-11-05
Abstract: In a DC very small commutator machine, having an iron-free rotor winding two opposite permanent magnet rings (154, 155) are provided on the stator in order to improve the angular degree, especially for battery operation, which permanent magnet rings form a flat air gap (153) between them into which the iron-free rotor winding (147, 148) projects. This winding is held on a supporting element (144) whose external diameter virtually corresponds to the internal diameter of the permanent magnet ring (155) surrounding it. In order nevertheless to be able to guide the connecting elements (165) of the rotor winding (147, 148) without damage to the flat commutator (122), the supporting element (144) has sections of reduced diameter between the rotor coils, on which sections of reduced diameter these connecting elements (165) are mounted (166). As a result of further measures, an axially extremely compact construction of the commutator machine is achieved, a type of labyrinth seal (168) being used to prevent grease or oils passing from the bearings (142) to the flat commutator (122).   <IMAGE>

Patent DE-3322235-A1 (DE)
Title: Circulation combustion engine
Inventor: MAMIC ZDRAVKO
IPC: F02B53/02
Filed: 1983-06-21
Abstract: The essential feature of this is the improvement and simplification of the cooling system. Instead of a fan a formed, hollow intake pipe is provided whence the intake air passes by way of an inner series of holes in the cover and rotor, whilst in the opposite cover deflection of the air occurs and this passes through the outer series of holes back to the pipe, thereby causing intensive cooling of the engine. The suction effect for the cooling air is produced by the speed of the exhaust gases.

Patent DE-3330589-A1 (DE)
Title: Engine and accessories, especially coal internal combustion engine and engine with measures to increase the power for a low weight
Inventor: EICKMANN KARL
IPC: F02B45/02
Filed: 1983-08-25
Abstract: The invention is concerned in particular with measures to increase the pressure and the temperature in the outer combustion chamber of a combustion chamber fed from a set of compressors and located between compressors and expansion systems, and at the same time to keep the entire engine or the combustion system reliable so that at the high temperature even solid fuel, for example in rod form, can be burnt at a certain rate of advance of the fuel rod. The temperature can be raised to such a level that the self-inserting fuel rod spontaneously ignites and burns. After combustion, overhot gas may be efficiently cooled by water injection and used for the output of work. In implementing the invention it emerged that, due to good compressors, valves and the combustion chamber design, such engines with outer combustion chambers can also function as petrol engines with levels of efficiency every bit as good as those of conventional spark ignition engines. Powdered fuel can also be burnt and the parts which serve to complete the engine may have other applications in hydraulics and pneumatics and in aircraft construction and vertical take-off of fixed-wing aircraft. Since the expansion systems in such engines deliver work on each downwards stroke, the engines are especially compact or they give increased power for given weight and dimensions.

Title: Process and device for forming a bent-back end part onto a plastics pipe part
Inventor: IRMER ADOLF
IPC: B29C57/12
Filed: 1983-10-28
Abstract: In a process and device for forming an end part, which is bent back preferably so as to be J-shaped in longitudinal section, onto a plastics pipe part with formed-on socket, an end part of an end extension of the plastics pipe part is bent back with the aid of a bending-back surface using a friction-reducing medium between the exterior of the end extension and the bending-back surface acting therewith. By this means, the desired bending-back can be achieved very rapidly with a single bending-back surface to form a bent-back end part, the bent-back end part being in addition optimally formed. A sealing element is reliably fixed in the pipe part by means of the bent-back end part.

Title: Composite material for spectacle frames and method of producing it
Inventor: KURAHASHI KAZUO
IPC: C23C26/00
Filed: 1983-11-04
Abstract: In the production of a composite material having a Ti core for spectacle frames, heat treatment is carried out at a selected temperature on an untreated composite material which is composed of the Ti core and a metallic sheath, in order to bring about a partial diffusion in solid solution from the metal or the metals forming the sheath, for example Ni, Au or their alloys, into the structure of the Ti core so that the composite material has a core zone comprising a Ti-base alloy and a surface zone composed of the metal or the metals forming the sheath. In this process, the spring properties and the mechanical strength are appreciably improved, with the result that the final product is particularly suitable for soldering and cladding.
