Patent EP-0271290-A2 (EP)
Inventor: STEIGERWALD ROBERT LOUIS
IPC: H02M3/337
Filed: 1987-12-03
Abstract: A digital data detector (27) is part of the primary side control electronics in a high voltage integrated circuit for regulating a power supply secondary side output potential; the detector output (27a) is responsive to the transitions of digital error data received from the supply secondary side via an electrically-isolated data transmission means. Only the transition edges are utilized by the detector, so that any non-linearity after each transition of the transmission means is immaterial. If the isolation device is a pulse transformer (17), the transformer core can be of relatively small volume, as full-pulse reproduction is unimportant and pulse saturation is tolerable. A multiplexer (33) allows the primary side control electronics to initiate power supply operation; control is switched to the secondary side responsive to signal edges therefrom being detected by the digital data detector.

Abstract: The present invention is directed to a structure for positioning electronic modules of an electronic system therein, and particularly to a rack often called a card cage in which circuit boards are disposed. The rack embodying the invention incorporates a frame having four sides and a back plate. Two of the opposite sides are grilles. The frame is adapted for supporting printed circuit boards perpendicular to the grilles. Thus, a fluid cooling medium, such as air, can enter the rack through one of the grilles, flow along and between the circuit boards and exit through the other grilles. The resistance to the flow of such air for cooling by the grilles is significantly greater than the boards disposed therein. Thus, the grilles permit a uniform coolant flow for each of the circuit boards in the rack. 
     The rack has a lever assembly which remotely actuates connectors positioned in the rack to contact the circuit boards positioned therein. The lever assembly is further provided with a spring member which serves as a force-limiting device such that excessive force is not applied to the boards and to the connectors when the boards are inserted into the rack. The rack also has guiding members for guiding warped circuit boards into position within the rack.

Abstract: A text comparator which includes a decoded data memory (13) which contains a plurality of shift registers (SR20-SR7F), one shift register for each one of the plurality of different symbols forming the data base stored within the mass storage device (11). The decoded signal is applied to the input lead of the shift register associated with that character, and a clock signal applied to each shift register of the decoded data memory. In this manner. the decoded data memory will provide signals on the output leads of each shift register indicative of the most recently received character, as well as each of the preceding K characters received from the mass storage device and decoded, where K is the number of bits contained in each shift register of the decoded data memory. 
     The output lead of the shift registers are connected to the input leads of a variety of logical gates, such as AND gates and OR gates, in order to provide an output signal indicating when the desired textual phrase has been located on the disk. 
     In addition, word counters, paragraph counters, and other devices are employed as desired to provide special text comparison functions. 
     A second embodiment of a text comparator constructed in accordance with this invention receives data stored in a mass storage device. This embodiment includes word logic, delimiter logic, set logic, set combination logic, proximity logic, and programming logic. The delimiter logic serves to monitor the characters transferred from mass storage device and provides discrete signals depicting whether the character being transferred is a predefined delimiter character. The word logic serves to store data regarding predefined words (i.e., strings of characters) which are to be located and provides output word signals indicating when such predefined words have been located. The set logic receives the delimiter signals and word signals and provides output signals when selected words are located in the same sentence, same paragraph, etc., as desired. The set combination logic serves to combine the signals from the set logic in order to generate output signals in response to more complex search strategies then can be easily detected by the set logic. The proximity logic provides output signals indicating when predefined words detected by word logic 112, or predefined set of words, as detected by set logic 114, or a combination of this information, occurs within a predefined proximity. For example, proximity logic 117 will determine if a first selected word occurs within N (where N is a selected integer) words of a second preselected word. The programming logic serves to receive search strategy instructions from the user and in response thereto provide the proper timing, addressing, and data signals the word logic, delimiter logic, set logic, set combination logic, and proximity logic to cause to be stored within these elements the information required to perform the desired search strategy.

Title: Isolation valve for vacuum and non-vacuum application
Inventor: JAKUBIEC ANTONI F
IPC: F16K3/18
Filed: 1988-09-19
Abstract: An isolation valve includes a housing having a port and a seal plate for sealing the port. The seal plate is linked to a shaft which carries a guide frame. To close the port, a drive mechanism drives the shaft linearly in one direction. The seal plate first moves linearly with the shaft until the guide frame stops against the housing. The seal plate then moves linearly in a direction perpendicular to a surface of the housing containing the port until it seals the port. Motion of the drive shaft in the opposite direction causes the seal plate to retrace its path. In one embodiment, the valve includes a second seal plate for sealing a second port. A spring between the guide means and the shaft provides pre-load which maintains the seal plates in a retracted position until the frame stops against the housing. An extension spring between the first and second seal plates eliminates play in the link mechanism and extends valve life.

Abstract: A system and method for controlling an ignition timing for a vehicular internal combustion, are dislosed in which a basic ignition timing is determined on the basis of engine operating conditions, i.e., an engine revolution speed and pulsewidth of a fuel injection signal supplied to an injection valve for each engine cylinder. A first correction quantity to correct the basic ignition timing is determined on the basis of a change rate of the engine revolution speed. A second correction quantity to correct the basic ignition timing is determined on the basis of an engine load. A final ignition timing is determined on the basis of the basic ignition timing and/or first and second correction quantities when the engine falls into a transient operating condition, any one of shift gear positions is detected, the gear shift positions including a position in which no engine driving force is transmitted to a vehicular power train. The final ignition timing is determined according to the gear shift range postion. In addition, when the gear shift is placed in the position in which no engine driving force is transmitted to the power train and the change in the engine revolution speed occurs, the basic ignition timing is determined to be the final ignition timing.

Abstract: For rolling complete cross-sections, e.g. bar stock and wire, the rolls (16, 17) of roll stands, which have three or more rolls, are fitted with clover-leaf grooves (18) which have projections (18a) corresponding to the number of rolls and indentations situated between them. The boundary surfaces (19) of the projections extend symmetrically to the planes (B) of division of the rolls and extend at a distance from the groove centre (M) which is equal to or slightly larger than the circumferential surfaces (20a) of the inlet cross-section (20) or of the blooming pass. By a substantial decrease in height taking place with a corresponding increase in length due to the geometry of the clover-leaf groove in the region of its indentations, an increase in length takes place in the projections of the clover-leaf groove practically by drawing along the cross-sectional parts not being under direct pressure, i.e. in the region of the projections (18a) the groove can remain underfilled. As a result, a spread-free rolling is made possible in order to implement the advantages of the single-pass oblique rolling process in a multi-pass forming and profiling of rolled stock. The row of grooves can also comprise circular grooves. <IMAGE>

Abstract: For obtaining pure water and products dissolved in water, the water is introduced in fine distribution into an inert carrier gas stream, a predetermined  partial pressure for the carrier gas being set in the carrier gas/steam mixture, which forms as a result of heating of the carrier gas/steam mixture until the steam thus generated is superheated. The solid particles are precipitated from the carrier gas/steam mixture. The purified carrier gas/steam mixture is cooled until the steam condenses, and the heat thus released is utilised within the process. For heating the carrier gas/steam mixture, the water to be purified is first partially vaporised by supplying heat and the brine formed in the partial vaporisation is introduced into the carrier gas stream. The steam formed in the partial vaporisation is at least partially compressed, after the brine has been separated off, and is used with heat release, on the one hand, for heating the carrier gas stream after feeding of the brine for adjusting the superheated carrier gas/steam mixture and, on the other hand, for partial vaporisation of the water. The purified carrier gas/steam mixture is utilised, with a condensation of the steam contained therein, for preheating the water which is to be purified. <IMAGE>
