Title: Power steering gear valve
Inventor: THOMAS ANDREW DONALD
IPC: B62D5/083
Filed: 1996-05-03
Abstract: A rotary valve for a hydraulic power steering gear has a sleeve with slots journalled to an input-shaft with grooves, the co-acting sleeve slots and input-shaft grooves defining axially extending orifices. The orifices are ported as a network such that they form primary (29) and secondary (30) hydraulic Wheatstone bridges arranged in parallel, each bridge comprising two limbs each of which communicates inlet and return orifices to respective inlet and return ports of the valve. The limbs of the primary bridge hydraulically communicate to a respective one of the cylinder ports (4, 5) at an interconnection point of the respective inlet and return orifices in that limb. The secondary bridge limbs do not hydraulically communicate to the cylinder ports. Hydraulic flow from the primary and secondary bridges is hydraulically communicated to the return port via respective primary and secondary return paths.     The secondary return path has an annular restriction (71) having a cross section to flow which has a high aspect ratio.

Title: Process for testing the operation of fittings
Inventor: STEIGLEDER NORBERT
IPC: G01M13/003
Filed: 1996-11-13
Abstract: A process is disclosed for testing if fittings are ready to operate. At least one measurement value for a fittings-specific variable is determined and compared with a previously established value. The measurement value is determined at the cold and non-pressurised state of the fitting and is compared with a value for the fittings-specific variable analytically determined from an operational model of the fitting. Upper and lower limit values associated with still admissible states of the fitting (design reserve) are established for this analytically determined value. It is shown that the fitting is ready to operate when the measurement value lies between the upper and lower limit values.

Patent CA-2258402-A1 (CA)
Inventor: KABS HERMANN
IPC: H01M8/1007
Filed: 1999-01-13
Abstract: A method and a device for testing the quality of a sheet-like element (1) comprising a membrane (2) are presented. The quality test is limited to a part area of the sheet-like element (1), in that a useful material (7), provided for the use of the sheet-like element (1), is fed to one side of the sheet-like element (1) via a useful-material outlet orifice (8) of a housing (5, 5a, 5b), the area bounded by the useful-material outlet orifice corresponding to the part area to be tested.     This method is appropriate, in particular, in the production of large-area membranes or membrane/electrode units provided for use in fuel cells. The quality test can take place in a simple way even during the production of these sheet-like elements (1). In this way, faults during production can be detected at an early stage and the production parameters changed accordingly.      In the case of the testing of an MEU for a fuel cell, fuel gas can be applied to one side of the MEU in a punctiform manner via the housing (5, 5a, 5b).    The oxygen of the ambient atmosphere located on the other side may serve as oxidation gas (11). While fuel gas (7) is being applied, the voltage generated between the electrodes (3, 4) of the MEU or the current flowing between them can be measured in order to check the quality of the MEU.

IPC: A61K8/365
Filed: 1997-08-26
Abstract: Improved one-part and two-part liquid products such as, e.g., mouthwashes, mouthrinses, toothpastes, gels and the like, for remineralizing subsurface lesions and/or mineralizing exposed dentin tubules in teeth contain a cationic component, an anionic component and a separating means for separating the cationic and anionic components. The anionic component contains water-soluble phosphate and fluoride salts, while the cationic component contains at least one partially water-soluble calcium salt and preferably at least one water-soluble salt of a divalent metal other than calcium. The tooth is treated with a mixed aqueous composition formed by mixing the cationic and anionic components with water and/or saliva. The mixed aqueous composition has a pH of from about 4.0 to about 10.0 and, in addition to dissolved calcium cations and dissolved phosphate and fluoride anions, contains a quantity of undissolved calcium salt. The use of the partially water-soluble calcium salt delays precipitation of the cations and anions in the aqueous composition until after the ions have diffused through the tooth surface to the subsurface and/or dentin so as to effect remineralization and/or mineralization, respectively.
