Title: Scroll spring for vehicles
Inventor: ORTWEIN ELISABETH
IPC: B61F5/30
Filed: 1988-12-23
Abstract: The invention relates to a scroll spring for vehicles, in particular rail vehicles, consisting of a spring housing and a spring-mounted pin which engages therein and which housing and pin are supported one above the other by means of a rubber ring arranged in the intermediate space between them subject to the effect of a vertical and/or axial and/or lateral force with spring compression in the region of a vertical and/or axial and/or lateral spring path, in which case, in order to simplify the mounting on the inner circumference and on the outer circumference of the rubber ring, inherently rigid, separate annular segments or enclosed rings whose rigid annular sections are connected to one another via extension areas or reduction areas are vulcanised on, and in that the rubber ring is inserted with the annular segments or the rings with expansion of the inner circumference and reduction of the outer circumference between spring housing and spring-mounted pin in a pretensioned state.

Title: Hose connection
Inventor: KROME HELMUT
IPC: B67D1/08
Filed: 1989-03-18
Abstract: The invention relates to a hose connection, in particular for taps for alcoholic and/or alcohol-free beverages and for pressure reducers for propellent gases, such as carbon dioxide and/or nitrogen, in the case of which hose connection a connecting piece which secures the hose can be pressed with the interposition of the seal, against a counter-surface on the connection part of a tap or the like, the connecting piece exhibiting a connection stub which is directed towards the hose and has at least one encirling annular bead over which the hose engages in the connected state, and the hose being pressed, by means of an annular, push-on pinch-type bushing which engages over it, against said connection stub in a sealing manner. Said hose connection is intended to be designed such that, while ensuring hygienically sound sealing, said hose connection has as short an overall length as possible. For this purpose, the invention provides that the connecting piece comprises the connection stub and a flange which bears the seal on its side which is directed away from the connection stub, a union nut engaging over the annular pinch-type bushing, the latter exhibiting a flange surface which is directed towards said union nut, and the union nut engaging on an external thread of the connection part and thereby displacing the pinch-type bushing as far as the flange of the connecting piece, while simultaneously pressing on the seal.

Title: Device for the supply of lubricant and coolant to a clutch of a motor vehicle transmission, shiftable under load
Inventor: GARTNER HELFRIED
IPC: F16D13/74
Filed: 1989-05-29
Abstract: A device for the supply of lubricant and coolant to a clutch of a motor vehicle transmission, shiftable under load, has a lubricant line (6) led from a pump (4) by way of a pressure-reducing valve (5). In order to manage with only one feed line to the clutch shaft (1) or another rotating clutch element whilst nevertheless ensuring a sufficient supply of lubricant and coolant, the lubricant line (6) and a pressure line (7) bypassing the pressure-reducing valve (5) are combined to form a common feed line (9). The pressure line (7) is closed by a control valve (8) opening only when the clutch is engaged. The common feed line (9) forks inside the rotating clutch element or the clutch shaft (1) into lines (2, 3) for the lubricant and the coolant. In the area of the fork the line (2) for the lubricant has a valve (11), loaded in the opening direction by a spring (10), and the line (3) for the coolant has a valve (13), loaded in the closing direction by a spring (12). The spring (10) acting in the opening direction is designed weaker than the other spring (12). <IMAGE>
Patent DE-3922320-A1 (DE)
Inventor: KYRIAKIS JOHN
IPC: G01B11/00
Filed: 1989-07-07
Abstract: To monitor a product such as a continuously moving cable 1 to determine its size and position during treatment in a hostile environment, the product is viewed through an inspection window 3 in a closed chamber 2 containing the hostile environment. To obviate inaccuracy in measurement due to the collection of contamination on the inspection window 3, the apparatus employs a source of radiation 5 arranged within the chamber, and a radiation detector 8 for viewing through the inspection window, with the cable interposed between the radiation source 5 and detector 8. A lens 7 focusses an image of the cable onto a CCD detector 8, and the detector array is scanned by circuit 9 to determine the light and dash regions requesting the position and dimension of the cable. <IMAGE>

Title: Coupling between trailer and towing vehicle - has play eliminated by automatic clamping device
Inventor: GLAESSNER RALF
IPC: B60D1/02
Filed: 1990-02-06
Abstract: The coupling connects a trailer to a towing vehicle. It has a mechanism to eliminate play between the two parts of the couplings (K). The coupling body (10) has a pin (12) which can slide vertically in an attached housing (14) and engages the eye (28) of the tow-bar (20).

Title: Data protection in computers with virtual disk - involves switching computer off electronically only after data secured on fixed disk
Inventor: KOLLER ROMAN
IPC: G06F11/14
Filed: 1990-03-12
Abstract: The method of protecting data in computers involves operating an external storage device using electronic switching off of the computer which also prevents the computer from being manually switched off.

Inventor: DREES FRIEDRICH-WILHELM DIPL P
IPC: H04N1/40
Filed: 1990-08-13
Abstract: In the printing process proposed, a multiplicity of image data (BD), each describing the half-tone gradation of a screen dot (RP) of the original image (VB), are transferred to processing zones (V15). From the image data (BD) in the processing zones (V15), colour-gradation values (FS0...FS5) are obtained which determine the shades of coloured dots (FP0...FP5) produced at selected points (DP) on a print screen. In order to produce a reproduction image (WB) with a large number of half-tone gradations (HS0...HS65), and at the same time achieve high resolution in areas of the original image (VB) showing a pronounced change in contrast, a colour-gradation value (FS1...FS5) is obtained from each item of image data (BU) by virtue of the fact that a colour-gradation value (FS1...FS5) in a reference pattern (R0...R65) associated with the half-tone graduation concerned (HS0...FS65) is allocated in accordance with the half-tone gradation (HS0...HS65) described by the item of data and its position (01...013) in the processing zone (V15).

Inventor: LUCAS CHRISTIAN
IPC: A63C7/10
Filed: 1990-08-31
Abstract: In a ski brake with brake arms (12) and actuating arms (14) a pedal (16) is mounted to the actuating arms (14) about a second transverse axis (15). A linkage arrangement (17) is provided approximately parallel to the actuating arms (14) and is pivotally connected to the pedal (16) about a third transverse axis (18) and to the ski about a fourth transverse axis (19). The fact that the spacing of the second transverse axis (15) from the third transverse axis (18) is somewhat smaller than the spacing between the first transverse axis (13) and the fourth transverse axis (19) means that the pedal (16) can execute a small counter-pivotal movement on transfer of the ski brake from the braking position into the rest position.
