Title: Railway electro-pneumatic brake valve and emulation method
Inventor: HART JAMES E
IPC: B60T17/22
Filed: 2000-02-04
Granted: 2003-06-03
Abstract: An electro-pneumatic brake control valve for performing electronic emulation is provided wherein multiple electronic valves control braking operations on freight cars.  Multiple pressure sensors are preferably used, and particularly a brake pipe pressure sensor for detecting pneumatic brake commands. In addition to using electronic valves to control brake application and release operations, an electronic quick service valve can selectively exhaust brake pipe to the atmosphere in a controlled rate and amount to assist the propagation of a quick service application and an electronic accelerated release valve can selectively connect emergency reservoir to brake pipe to assist in restoring brake pipe pressure and in propagating a direct release of the brakes. The electro-pneumatic control valve also preferably includes a microprocessor for signal and command interpretation and valve control.

Abstract: The method for the shaping of strip-like films (2), comprises the following steps:   a) A film strip (2) is continuously forwarded from a film supply to shaping units, b) The film strip (2) is pleated in a first shaping unit (11). In this, edges (21, 22) are produced which form an angle of inclination to the edges (36) of the film strip having a constant value.   c) After a forwarding of the pleated strip (2') to at least one further shaping unit (12) the former is reshaped in one or more steps. In this the edges (21, 22) are eliminated through plastic deformation by means of a roller pair (120) in edge zones (30b) outside of a middle zone (30a) of the strip and are at the same time replaced by curved edges (31, 32).        The angles of inclination of the curved edges continuously increase from the middle zone to the strip edges.

Granted: 2009-07-14
Abstract: The present invention provides a method and system (1) for pattern recognition and processing. Information representative of physical characteristics or representations of physical characteristics is transformed into a Fourier series in Fourier space (12) within an input context of the physical characteristics that is encoded in time as delays corresponding to modulation of the Fourier series at corresponding frequencies. Associations (14) are formed between Fourier series by filtering the Fourier series and by using a spectral similarity between the filtered Fourier series to determine the association based on Poissonian probability. The associated Fourier series are added to form strings (16) of Fourier series. Each string is ordered by filtering it with multiple selected filters to form multiple time order formatted subset Fourier series, and by establishing the order through associations with one or more initially ordered strings to form an ordered string. Associations are formed between the ordered strings to form complex ordered strings (18) that relate similar items of interest.

Granted: 2007-10-02
Abstract: The invention relates to a plug (10) for fastening to hollow or panel-type building materials and to solid building materials. The invention proposes providing the plug (10) with expansion limbs (18) that extend longitudinally and that are connected to one another by thin skins (22) having a corrugation in the peripheral direction. That has the advantage of good screw guidance and a torsionally rigid construction of the plug (10); especially when fastening to hollow and panel-type building materials, undesirable backwards rotation of the plug tip (16) is avoided when screwing in an expansion screw by hand. Angled slits (32) in the plug tip (16) bring about good adaptation to screws having different diameters and different pitches of thread.
