Title: Device for height adjustment of a safety belt fittings
Inventor: PETZI JURGEN
IPC: B60R22/24
Filed: 1994-07-29
Abstract: In the case of a device for the height adjustment of a safety belt fitting in vehicles, a load-accommodating guide rail (10) which is set up for fastening to the vehicle has a plurality of locking elements (21) which are at a longitudinal distance from one another. A support (12) is displaceably accommodated in the guide rail (10) and has the safety belt fitting fastened to it. A bolt (22) which can be selectively engaged with the locking elements (21) is mounted on the support. Actuation of a release element (26) causes the bolt (22) to be released from the respective locking element (21). The bolt (22) is mounted on the support (12) so as to be pivotable about an at least approximately horizontal pivot axis (A) and its centre of gravity (S) is offset with respect to a plane (E), which passes through the pivot axis (A) and is parallel to the guide rail (10), to the side of the guide rail (10). If the support moves suddenly downwards owing to tightening of the belt, the bolt (22) is forcibly swung into its locking position under its own mass moment of inertia. <IMAGE>

Title: Glass coating process
Inventor: KIRKBRIDE BERNARD JAMES
IPC: C03C17/00
Filed: 1996-07-22
Abstract: A method of providing a tin oxide coating on a moving flat or float glass substrate by chemical vapour deposition by pre-mixing gaseous streams of tin tetrachloride and water at a temperature of between 100°C and 240°C and directing the unitary pre-mixed stream against the glass in substantially laminar flow, the tin tetrachloride and the water only reacting in the region of the surface of the glass to form the tin oxide coating on the glass. Alternatively, gaseous streams of anhydrous hydrogen chloride, tin tetrachloride and water may be premixed to form the unitary pre-mixed stream, which pre-mixed stream impacts the glass in substantially laminar flow, the tin tetrachloride and the water reacting with one another in the region of the glass to form tin oxide which forms a coating on the glass.

Title: Cellulose fibrous structure with at least three regions distinguished by intensive properties, process of its production and apparatus for making the same
Inventor: PHAN DEAN VAN
IPC: D21F11/00
Filed: 1992-06-22
Abstract: Disclosed is a cellulosic fibrous structure, such as paper. The fibrous structure has at least three intensively distinct regions. The regions are distinguished from one another by intensive properties such as basis weight, density and projected average pore size, or thickness. In one embodiment, the fibrous structure has regions of two basis weights, a high basis weight region and a low basis weight region. The high basis weight region is further subdivided into low and high density regions so that a fibrous structure having three regions is produced. A second embodiment is a four region fibrous structure. Two of the regions have generally equivalent relatively high basis weights and two of the regions having generally equivalent relatively low basis weights. The high basis weight regions and low basis weight regions are further subdivided according to relatively high and relatively low densities, so that when the high and low basis weight regions are permuted with the high and low density regions, four different regions result. The regions distinguished by density will have inversely proportionate projected average pore sizes.

Patent SK-132009-A3 (SK)
Title: Tester dynamic errors of digital/analog converters
Inventor: LINUS MICHAELI
IPC: G01R31/00
Filed: 2009-02-23
Abstract: Dynamic error tester for digital-to-analog converters (1) uses a comparison of sawtooth voltage generated by the tested digital-to-analogue converter (1) with a DC voltage generated by the reference digital-to-analog converter (3) and measured by the digital multimeter (4). This comparison is carried out by the voltage comparator (2). The pulse width at the output of the voltage comparator (2) is evaluated as the ratio of the number of pulses which release the gate (5) controlled by the output of the voltage comparator (2) to the pulse counter (6) to the total number of pulses generated by the control computer (7). This ratio determines the non-linearity over the tested digital-to- analog converter (1). The main contribution is replacement of the necessary precision measurement of the output voltage of the tested digital-to-analogue converter (1) by measuring the time intervals, counting the number of pulses. The accuracy of the tester of the digital-to-analogue converters is determined by the precision of the digital multimeter (4) as a basic measuring device, without the necessity of accurate dynamic voltage recorder. Tester accuracy can be improved by increasing the number of pulses used to calculate the non-linearity.

Title: Cable with impact-resistant coating
Inventor: BELLI SERGIO
IPC: H01B7/00
Filed: 1998-05-08
Abstract: The present invention relates to a coating for cables which is capable of protecting the cable against accidental impacts. By inserting into the structure of a power transmissioncable a suitable coating of expanded polymer material of adequate thickness, preferably in contact with the sheath of outer polymer coating, it is possible to obtain a cable which has a high impact strength. The Applicant has moreover observed that an expanded polymer material used as a coating for cables makes it possible to obtain a higher impact strength for this cable than using a similar coating based on the same polymer which is not expanded. A cable with a coating of this type has various advantages over a conventional cable with metal armor, such as, for example, easier processing, a reduction in the weight and dimensions of the finished cable and a lower environmental impact as regards recycling of the cable once its working cycle is over.
