Patent DE-3903767-A1 (DE)
Title: Device for manually clamping and freeing disc-shaped working tools for electric tools
Inventor: GOECMEZ MUSA
IPC: B24B45/00
Filed: 1989-02-09
Abstract: In the case of a known device of this type, the clamping flange bearing on the working tool is freed of the clamping force for the working tool by the fact that the supporting means which secure the flange against axial displacement on the working spindle are movable transversely to their supporting direction into an alternative space, as desired. The new clamping device is to make possible an extremely low construction of a quick-clamping device with a minium of expenditure and while avoiding movable supporting means. The supporting means are fixed components of the clamping nut (12) and of the clamping flange (13). In the clamped state of the working tool (16), they exclude the possibility of a relative movement between clamping flange (13) and clamping nut (12). <IMAGE>
Patent DE-3905057-A1 (DE)
Inventor: VOEHRINGER GERHARD F
IPC: B05B14/48
Filed: 1989-02-18
Abstract: Crude gas with coating powder is extracted from the spraying space (4) of a powder spraying booth through an outlet opening (17), at an elevated position, of the booth side wall (6). Here, the powder particles collect on the booth floor (3) mainly below the outlet opening (17). In order to prevent precipitation, a shutter (22) which is part of an extraction shaft (211) is mounted upstream of the outlet opening (17). Said shaft is swivellably mounted at its upper end in a joint (23) and can rest with its side walls against the booth side wall (6) with adjustable inclination and adjustable opening width of gaps (39). Just above the booth floor (3), it forms a suction shoe (36) which sucks up the powder directly from the booth floor through a suction gap (37). Extraction openings (331) are mounted on the walls and on the top of the extraction shaft. Crude gas can flow into the outlet opening (17) from almost all directions parallel and transversely with respect to the side wall (6). These largely laminar flows meet with reduced flow speed in the region of a slot (38) surrounding the outlet opening (17). In this way, the powder not precipitated at the workpiece is sucked into the outlet opening before it can be precipitated at the floor or a wall.

Inventor: DOKOUPIL JIRI DIPL ING
IPC: C14B1/00
Filed: 1989-08-25
Abstract: When processing leather and similar materials in a series of successive steps, the surface dimensions of the leather are often altered. The particular properties of leather make it necessary, therefore, to monitor such changes in surface area. In order to rationalize and to improve the quality, a process is proposed comprising a series of successive spreading and stretching steps. In this process, the area is measured before and/or after the stretching operation. An associated system comprises a transport device (7) extending along a processing line for a series of consecutive disposed leather items (L), plus a subsequent spreading station (1) with a flat surface extending beyond the edges of the leather item, plus at least one subsequently located  processing station (2, 3) before or after which an area-measurement device (Ia, b, c-- IIIa, b, c) is located.

Title: IC engine cylinder head - has tappet openings of cross=sections comprising curved ends and outwards-arching sides
Inventor: SCHAEFER FRED PROF
IPC: F01M9/10
Filed: 1990-02-01

Title: IC engine control and activity information processing method - using multiple controlling to process information etc. in different planes independently
Inventor: MILLER NORBERT DIPL ING
IPC: F02P5/15
Filed: 1990-02-14
Abstract: A method of processing information and activities arising from the control of internal combustion engines involves using several controllers operating on information and activities in processing planes with different  interdependencies. At least two controllers are used which process the information and activities in the different processing planes mutually independently. E.g. the first controller processes information and activities in a time-synchronous-plane and the second in an angle-synchronous plane. USE/ADVANTAGE - The method enables better use to be made of existing controllers and several requirements to be met without adverse interplane effects.

Abstract: A cutting device for a wire removing machine for cutting through tie wires of bales, in particular cellulose bales, has essentially two elongate cutters (5, 6) that can move back and forth in relation to each other, each provided at their cutting edges with a row of regularly spaced teeth (16, 17) having an undercut on their front flanks, in the cutting direction. In order to precisely define the moment when the wires are cut and at the same time ensure that a gripping device has already reliably clamped the tie wires before they are cut through by the cutting device, the front flanks (18, 19) of the teeth (16, 17) have at their lower end, in the area of the tooth root, a receiving pocket (21, 22) for at least one tie wire, the back ends of the receiving pockets (21, 22) forming knife-edges (24). The sections of the front flanks (18, 19) of the teeth (16, 17) that extend between the tip (20) of the tooth and the corresponding receiving pocket (21 or 22) form blunt slide edges.
Patent DE-4008310-A1 (DE)
Inventor: EICHLSEDER MARTIN
IPC: B29C45/40
Filed: 1990-03-15
Abstract: In order to reduce the number of operations required for taking injection moulded objects out of the mould and to avoid the risk of soiling the surface, in particular in the production of optical data media, the use of retaining rings is proposed, which rings are arranged radially movably in the parting plane of the mould. The inside diameters of the retaining rings 4 in this case correspond to the outside diameters of the injection moulded objects 3, the inside diameters having a retaining geometry which ensures a secure retaining of the injection moulded objects 3. After completing the injection moulding operation and after opening the mould, the retaining ring 4 can be moved out of the mould sideways together with the injection moulded object 3. After cooling and the accompanying shrinking of the injection moulded object 3, the latter can be removed from the retaining ring 4.

Patent DE-4109743-A1 (DE)
Inventor: KROEHL PAUL DIPL ING DR
IPC: C04B11/02
Filed: 1991-03-25
Abstract: Both drying and the extraction of water of crystallisation can be performed in a fluidised bed apparatus (A, B) without any danger of overheating. This is attained via complete, uniform fluidisation by indirectly heated hot gas. A substantial quantity of energy is transferred to the fluidised layer via heat exchanger systems (4 and 12). These are heated by heat-conveying media. The structural layout of the fluidised bed apparatuses (A, B), the base plan of which is rectangular, ensures a narrow dwell period spectrum and an excellent temperature/moisture curve without the assistance of various fluidised chambers. Owing to the relatively cold introduction area and gentle heating thus produced, the properties of the crystals are favourably affected. The product is distinguished by very uniform quality. No undesirable modifications to the gypsum occur when moist gypsum is calcined.
