Title: Device for releasing the closure caps on the valves of tyres of motor vehicles
Inventor: MICHELS HERBERT
IPC: B25B27/00
Filed: 1984-04-13
Abstract: The invention relates to a device for releasing the closure caps (3) on the valves of tyres of motor vehicles, by means of which the unpleasant operation of refilling the tyres with air is to be made easier. If it is desired to test the air pressure in the tyre, the closure cap (3) must be unscrewed and, after testing or refilling with air, must be screwed on again. The outside of the closure caps is frequently heavily soiled with oil and dust after travelling for a considerable amount of time and the fingers of the person testing the air pressure become dirty. In addition, frequently at least one of the wheels whose tyre pressure is to be tested is in such a position that the valve is located in the lower region of the wheel and, in order to be able to release the closure cap, the person in question must bend very low. These difficulties and discomfort are eliminated by means of a device which has a gripping piece (1) which bears a sleeve (2) which can be fitted onto the closure cap (3) and whose inside is constructed in such a way that, in the fitted state, it surrounds the closure cap (3) and, after pressure is exerted in the direction of the axle, is coupled to the said cap fixed in terms of rotation but can also be pulled off from the closure cap (3) when desired by pulling in the axial direction. In a preferred embodiment, the inside of the sleeve (2) has the cross-section of a regular hexagon and bears a locking device. A spring ring (7) which ... has been proven as a lock device ...

Title: Optical measuring arrangement with fibre-optic light transmission
Inventor: MARGUERRE HANS-HELMUT DIPL PHY
IPC: G01D5/26
Filed: 1984-09-11
Abstract: The invention relates to an optical measuring arrangement in which light is transmitted via fibre-optic transmission links (OÜ, OÜ') to an object to be measured (MO) and from the latter to an optical sensor (OS). At the object to be measured, light parameters, in particular the intensity, are influenced in a manner dependent on a physical variable to be measured. In order to obtain good sensitivity of the measuring arrangement even in the case of difficult reflection behaviour of the object to be measured (MO), a retroreflector arrangement (RR), which ensures a low-loss light return into the transmission link (OÜ), is fitted in the region of the object to be measured (MO). The invention can be used in particular in the case of fibre-optic sensors in production engineering. <IMAGE>

Patent DE-3525955-A1 (DE)
Inventor: LE THANH-SON DIPL ING
IPC: F16B19/02
Filed: 1985-07-18
Abstract: Through bolt connection for unilaterally accessible locations. The through bolt has a cylindrical head disposed eccentrically to the centerline of the bolt by a measure e, and a sleeve disposed likewise eccentrically to the sleeve centerline by a distance e. The bolt is received in the sleeve and together they are thrust into the through hole in the parts to be fastened. Head and sleeve are of the same diameter, so that they can be inserted together head-first in the through hole in one single position relative to each other. After the bolt head is located outside the through holes, the bolt is rotated through an angle of 180 DEG  to the other side so that now, owing to the eccentricity, the head catches over the edge of the through hole and its bearing surface is in contact with the surface on the inaccessible side. In this position, a nut with washer may be screwed on and tightened with the sleeve performing the function of a locating pin.

Title: Fuel injection arrangement of a piston internal combustion engine
Inventor: GALUSKA KAROL DIPL ING
IPC: F02F1/24
Filed: 1985-08-10
Abstract: The injection arrangement contains at least one fuel injection valve (6) with a nozzle body (10) arranged in a through opening (17) of a cylinder cover (1) of the internal combustion engine, which nozzle body has a head section (10a) with nozzle apertures (11) for the formation of fuel jets (12). On the inner surface (18) of the cylinder cover (1) a trough-like depression (15) extending the through opening (17) is formed, in which the head section (10a) is sunk. The combustion-chamber end of the head section (10a), viewed from the combustion chamber (4a), essentially lies on the other side of an imaginary reference surface (18a) which is defined by those sections of the inner surface (18) of the cylinder cover (1) adjacent to the depression (15). The depression (15) is formed by sections of the surface which run at a distance from the paths of the fuel jets (12) and thereby permit an undisturbed fuel feed. At the same time the surface temperature of the sunken head section (10a) of the nozzle body (10) is kept below the part-melting temperature of the non-combustible parts of the fuel, thereby preventing high-temperature corrosion of the nozzle body (10). <IMAGE>

For this purpose, at least one centring opening is provided either on the underside of the milling cage or on the milling cage-supporting surface of the guiding device, into which opening there engage, when the router is placed on, centring extensions which project at right angles away from the milling cage-supporting surface of the guiding device or at right angles away from the underside of the milling cage.
Patent DE-3544753-A1 (DE)
Title: Rotary swaging machine
Inventor: BINHACK FRITZ
IPC: B21J7/16
Filed: 1985-12-18
Abstract: The invention relates to a rotary swaging machine consisting of a swaging shaft with radial swaging movements - swaging rams - a ring of pressure rollers in a roller cage and an outer ring, the intention being to avoid displacement of the oil or lubricating film and the associated seizure and dislodging of the pressure rollers from their position of support in the roller cage by the radial forces which occur during swaging. For this purpose, the pressure rollers are accommodated in radial slots of the roller cage which have a diameter corresponding to that of the rollers, with the result that the pressure rollers can follow the expansion of the outer rings during swaging without having any effect on their bearing bores. <IMAGE>
