Title: Electro-hydraulic control device
Inventor: HONIG ERNST-AUGUST DIPL ING
IPC: F16H61/12
Filed: 1988-10-26
Abstract: An electro-hydraulic control device for an automatic shift transmission of vehicles, especially passenger motor vehicles, is described, which has a torque converter and a planetary gearing with shift elements, essentially comprising couplings (1-3) and brakes (4) and acting on the transmission elements, which shift elements in order to select individual transmission gears can be engaged in changing combinations by the application of hydraulic pressure. At the same time it is proposed that for the application of pressure electrically actuatable gearshift valves (5-8) be assigned to at least some of the shift elements (1-4), which valves in a first position connect a pressure admission line (34, 47, 77, 127), leading to the associated gearshift element, to a connecting line (12, 13), which as a function of the position of a manual control valve, adjustable by the operation of a selector lever, carries the main pressure, and in a second position to an outlet line (33, 63, 108, 109, 130). In order, also in the event of a failure, to ensure safe operation, sufficient at least for transfer to the nearest garage, it is proposed that, in the event of a failure of the power supply, the individual gearshift valves (5-8) be acted upon in order to set them into positions such that pressure is applied to gearshift elements (1-4) obtaining different transmission gears as a function of the position of the selector lever (Fig. 1). <IMAGE>

Title: Process and apparatus for furnishing foods with a surface mark by thermal treatment and foods thus marked
Inventor: PILIERO ROCO
IPC: A23L5/30
Filed: 1988-10-28
Abstract: In a process for furnishing foods, such as dairy products, with a surface mark (label) by heat treatment, the food to be treated is exposed unwrapped and with solid consistency to at least one laser beam, the beam properties of which can be selected and controlled in such a way that local heating of the food to be treated is achieved by means of which, on the one hand, a branding operation is achieved at least essentially in the region of the point of impact of the laser beam without significant evaporation and, on the other hand, the heating of the food to be treated is restricted to the immediate vicinity of the point of impact. Thus marking can be realised directly on the food to be marked, which marking is variable in its dimension, is, if required, uniform despite an irregular surface of the food, is, if required, variable in the form of gradations of brightness independently of the state of the surface of the food, has a distinct contour, does not disadvantageously influence the food in its entirety and substance and is possibly provided with a more or less variable colour, preferably more or less light or dark brown.

Filed: 1988-11-17
Abstract: The invention relates to a sealing configuration for an automatic tube weapon, especially for firing ammunition with a non-metallic casing, as well as a tool for installation and removal of the sealing configuration. The sealing configuration (18) according to the invention, whose life and sealing effects are improved over those of conventional sealing configurations, consists essentially of an annular housing (20), an annular spring (24) which surrounds the housing (20), and a sealing packet (38) which consists of a plurality of concentrically arranged sealing rings. When a shot is fired, the annular spring (24) is acted on radially by the gas pressure through radial holes (50) in the housing (20), and the sealing packet (38) is acted on both axially and radially, via gas ducts (52) in the housing (20). Using the tool according to the invention, tilt-free simple installation and removal of the sealing configuration (18) according to the invention are possible without any additional tool. <IMAGE>

Abstract: Method for filling a seed bed, or plant containers arranged alongside one another in columns and behind one another in rows on pallets, with small-grain seeds which have been delivered after separation to an ejector nozzle, characterised in that the seeds are ejected via an ejector nozzle which can be moved both in the transverse direction and in the longitudinal direction over the seed bed or the pallet. In this case either the ejector nozzle can be moved by means of a program-controlled x-y actuator in column steps or row steps both in the transverse direction and the longitudinal direction, respectively, over the seed bed or the pallet, or the ejector nozzle is moved in the transverse direction in steps in each case corresponding to one column spacing and, when the end position, as viewed in the transverse direction, is reached, the pallet is moved in the longitudinal direction by a step corresponding to one row spacing. The device consists of a seed separtion unit which is formed by a vibrator channel and is connected to a seed receptacle (2), and of an ejector nozzle (3), in each of which there is a light barrier emitting an impulse when interrupted by a seed grain falling through, the first controlling the vibrator motor of the seed separation unit and the other controlling at least one of the two servomotors effecting the carriage advance. <IMAGE>

Title: Shaft-hub seal
Inventor: ALT CLAUS-CHRISTIAN DIPL ING
IPC: F16J15/3256
Filed: 1989-03-25
Abstract: In the case of a shaft-hub seal with different pressures in the spaces to be axially separated from one another, the sealing element is designed as a ring with a U-shaped profile. The open U side faces the space at higher pressure, so that the U legs are radially forced apart to increase the sealing action. Of the two U legs of the sealing element, the one which bears fixedly against the opposed sealing surface is designed as a closed ring, in particular a sheet-metal ring, while the slidingly sealing second U leg consists of individual radially resilient tongues which are covered at least radially externally with a continuous elastomer layer having a radially sealing action.

Abstract: A roller-drive unit, in which the drive rollers (10, 10') are mounted by means of a pivot mounting (16), fastened to a frame (36), for the rotationally movable mounting of the drive rollers (10, 10'), is known. The drive rollers (10, 10') can be pivoted from a lower position of rest into one of two upper working positions, depending on the direction of rotation. A drive motor (34, 35) for the controllable drive of the drive rollers (10, 10') is provided. A torque is branched off from the motor drive torque via braking devices (22a, 22b; 23), in order to load the pivot mounting (16) in the direction of one of the working positions. When a travelling article to be conveyed comes up against the respective raised drive roller, a torque loading the arrangement in a pulse-like manner takes effect. It is proposed to provide a torsion spring (33) in the gear train between the drive motor (34, 35) and the braking device (22a, 22b; 23). <IMAGE>
