Title: Oil pressure regulating device
Inventor: KASHIWAGI MASAO
IPC: F15B11/05
Filed: 1998-08-19
Abstract: A pressure compensation valve (6) holds the pressure of the lower flow side of the variable throttle (8) of the changeover valve (2) by a specific pressure higher than pressure of the pilot line (13). A regulating mechanism (15,16) holds the pump delivery pressure higher by a specific pressure than the pressure of the pilot line. A positioning member is provided to which operating oil is fed after pressure compensation by the pressure compensation valve (6).

Title: Folded molding production used for forming e.g. plastic display pocket, involves stress-free intersecting, curved and three-dimensional folds in line-heated plastic sheet in free space, with no tooling marks
Inventor: HANNECKE WOLF-DIETRICH
IPC: A47F7/14
Filed: 1998-11-05
Abstract: The plastic is formed (folded by bending the blank) in free space, avoiding use of straight edges and folding dies. The required forces (slight) are introduced through non-heated areas.  Independent claims are also included for: (1) Formation of e.g. a plastic display pocket. It is made of homogeneous or modified polymethyl methacrylate. (2) Production equipment comprising blank-holding and bending equipment.  Preferred features: Formation is by folding along lines. During holding for formation, the section is heated along lines for folding, with wide heating zones for expansion and impressing. To make projections, a plunger is used locally, within a heating zone. Temperature and/or width of the heating region, varies along the line of forming, for desired formation of the fold edges, as a function of the material substance and thickness. Nearby, intentional cooling takes place. By heating along a curve, the product is given a (three-dimensionally) curved surface. During folding, hot molding takes place, with mechanical upsetting, forming reinforcement ridges along the forming lines. U- or  OMICRON  folds are produced by material expansion on the lines of formation. The surface is given a textured or profiled surface on one or both sides. Recesses, optionally in a pattern, are formed as a result of heating and deformation. Before heating and reforming, the material is embossed or engraved and/or blank assemblies are arranged upon it. Material thickness is preferably about 6.5. mm. Preferred equipment includes a heating unit covered by similar or differing heating elements (104). Cylinder (108) units with suction cups (110) are used for bending and holding the material (106). They are mounted to rotate on end trunnions.

Inventor: PIERZYNA KLAUS
IPC: B01D19/00
Filed: 1999-04-19
Abstract: The invention relates to a method and a device (10) for treating a hydraulic fluid (26). Extraneous components which are solved in the hydraulic fluid (26) are withdrawn by producing a pressure (p), especially a vacuum, that is reduced in relation to the ambient pressure. The time (t) required for obtaining the pressure (p) is measured and compared to a given value (tF,  DELTA t). The given value (tF,  DELTA t) matches the time corresponding to the production of the vacuum in a hydraulic fluid (26) without extraneous components. The amount of the extraneous components and thereby the quality of the hydraulic fluid (26) can thus be concluded.
