Patent DE-3606728-A1 (DE)
Inventor: HEEGE BERNHARD ING GRAD
IPC: A63G7/00
Filed: 1986-03-01
Abstract: The water jump way comprises a jump track (8), a boat (20) and a water basin. The boat (20) has front and rear wheels (21, 22) with a different track width. In the jump-off region (28) of the track (8), the running surface (25) for the rear wheels (22) is curved upwards to a lesser extent than the running surface (24) for the front wheels (21). It is thus achieved that, after the front wheels (21) have been lifted off from the end (27) of the track, the twist of the boat (20) is only slightly reduced despite the long wheel base and different loading of the boat (20) and consequently the landing angle of the boat (20) in the basin can be kept in a favourable range. This allows a circulation of the boats and a crew of more than one person.

Title: Thin-film circuit and a method for its production
Inventor: OETZMANN HENNING DIPL PHYS DR
IPC: H01L21/70
Filed: 1986-11-11
Abstract: The thin-film circuit has at least two resistors, to be precise at least one high-value resistor (5) consisting of Cr-SiO-cermet (ceramic-metal material) or Cr-Si (2) and at least one low-value resistor (11) consisting of NiCr (8). A thin aluminium layer (3) is used as the connecting contact (6) to the high-value resistor (5). The conductor tracks (12), which consist of a conductor layer (9) - for example of nickel with electrochemical reinforcement, for example of nickel and gold (10) - of the circuit engage over the connecting contact (6). Since the thin-film circuit is produced using a two-stage process with two different tempering processes at different temperatures, each resistor type can be optimised separately to a temperature coefficient starting from zero. In this case, in the case of the first high-temperature treatment, the thin aluminium layer (3) is used as a good resistive high-temperature contact to the Cr-SiO-cermet or Cr-Si layer (2). <IMAGE>

Abstract: The gun, e.g. for spraying paint, has a needle valve 8 arranged directly behind the paint outlet nozzle 13 and a paint duct 24 leading to the nozzle 13 and accommodating a high tension electrode 12. A plastics rod 8 of the needle valve extends through the paint duct 24 and where the rod 8 is introduced into the paint duct 24 it is sealed by means of suitable components 5, 6, 7 against high tension, the components being made of insulating material. The paint duct 24 is connected with a plastics hose 19 which in turn is connected with a metallic inlet junction 20 earthed together with a metallic hand grip 1 of the spray gun. In this way the earth point 21 of the paint duct 24 is removed from the interior of the spray gun to the outside and the paint duct 24 is extended between the high tension electrode 12 and the earth point 21 in order significantly to increase the electric resistance. By this extension it is made possible to spray electrostatically paints of lower specific as well as metal-particle-containing so-called metallic-effect paints efficiently. <IMAGE>

Title: Brake booster
Inventor: KEHL GEORG
IPC: B60T13/14
Filed: 1987-10-17
Abstract: A brake booster in a housing is proposed, with a servo piston slidably supported in the housing and a piston rod extending into the housing for the transmission of a brake force. At the same time, a pressure chamber is provided for receiving brake fluid, coming from an accumulator or reservoir after the opening of a valve designed as a control slide valve and delivered by way of a pump or the like, the pressure chamber in turn being connected by the control slide valve to a return line to the reservoir. In order to improve the sealing between servo piston and control slide valve, the piston rod engages in a cylinder bore of the servo piston and there encounters the control slide valve, which is provided with window passage for making the return line and with control ducts for making a feed line for servo brake fluid. At the same time, window passage and control ducts have control edges which interact with annular surfaces formed out of the cylinder bore, annular chambers being formed between the annular surfaces. <IMAGE>

Patent DE-3801561-A1 (DE)
Title: Valve device
Inventor: MIETH HANS OTTO DIPL ING
IPC: F16K3/24
Filed: 1988-01-20
Abstract: The invention relates to a valve device with at least one closing member, which is of slide-like design and has at least one radial seal interacting with a cylindrical seat area of the valve-housing parts, or two such seals with a leakage space arranged between them and connected to the atmosphere by at least one conduit arranged in the closing member and, if required, to a cleaning-agent feed by a second conduit. The use of the device proposed ensures, inter alia, that the closing member of a valve of the generic type described at the outset can be fitted with a single "loose" radial seal and that in a valve in which the closing member has two radial seals with a leakage space arranged between them, the said leakage space can be controlled even in positions other than the closing position of the valve. This is achieved, inter alia, by the fact that, in positions other than the closed position, a closure part (5) is substituted for the seat area interacting with the seals (7; 71, 72) in the closed position (Figure 2). <IMAGE>

Title: Method and pressure-cooling aggregate for cooling passing-through hot production material of steel and other materials, by controlling the heat absorption via continuously adjustable pressure-water orifice plates
Inventor: KRENN WALTER DIPL ING
IPC: C21D1/62
Filed: 1988-05-20
Abstract: Method and pressure-cooling aggregate for cooling shaped hot material, of any cross-section and large dimension range, in pressure water. In order to avoid the changing of the rigid orifice plates in the pressure-cooling aggregate, largely to eliminate damage to the surface of the material being cooled as a result of it running onto the rigid orifice plates, to make it possible for the material being cooled, of irregular cross-section or different partial cross-sections, to be able to be cooled inside pressure cooling aggregates in the pressure water, the pressure spaces in the pressure cooling aggregate are formed by continuously adjustable hydraulic orifice plates, as a result of which it is possible, by corresponding control of the cooling pressure water and the orifice-plate pressure water, for the heat absorption from the material being cooled to be so finely controlled and performed that the cooling temperature can lie within an extremely small range.
Patent DE-3818688-A1 (DE)
Title: Device to prevent the sticking of sealing elements on valve pistons, moved only occasionally, for pressure medium-actuated brake systems of vehicles, especially commercial vehicles
Inventor: FUCHS CHRISTIAN
IPC: F16J15/32
Filed: 1988-06-01
Abstract: In valves for pressure medium-actuated brake systems of vehicles, especially commercial vehicles, designs are provided in which pistons, slide valves or similar elements, carrying seals and actuated by pressure medium, are moved only occasionally, resulting in the risk of sticking of the sealing elements in relation to the housing parts to be sealed off. In order to prevent such sticking of the sealing elements, a device is proposed, by means of which the said sealing elements are subjected to an enforced movement when pressure is applied but the piston remains stationary. In a trailer control valve the sealing elements provided on the circumference of a control piston (11) are arranged as O-rings (37, 39) on both sides of a spring (45), the spring (45) being supported on the O-rings (37, 39) by means of a projecting spring leg (49) and the O-rings, for their part, being displaceable to a limited extent on the outer circumference of the control piston (11). A pressure applied to both sides of the piston results in the O-rings being moved to face one another against the spring force of the spring (45), that is performing an enforced movement, as a result of which the risk of sticking is prevented in the event of prolonged immobilisation of the control piston. <IMAGE>
