IPC: H01H33/02
Filed: 1990-02-05
Abstract: A metal-clad, compressed gas-blast circuit-breaker (1) with a gas-filled housing (2) and with an interrupter unit (3), which is supported, insulated in the housing (2), has at least one insulating drive rod (26) coupled to the switching contact (20) to actuate a movable switching contact (20).  This drive rod (26), which is connected to the interrupter unit (3), extends through a controlling element (5), which takes up and guides the flow of the switching gases at the time of the switching-off operation, as well as through a hollow post insulator (4) connected to the controlling element (5).  The controlling element (5) allows only a portion of the switching gases to pass through in the direction of at least one drive rod (26) and diverts the remaining portion in an at least radial direction.  In this manner, the pressurization of the drive rod (26) and the post insulator (4) by the switching gases is reduced.  The circuit-breaker is especially suited for application in gas-insulated, metal-clad, high-voltage switching stations.

Filed: 1990-03-15
Abstract: PATENT - Docket 90-RG-17571 - Cecil AN IMPROVED DRIVE MECHANISM FOR RETRACTABLE DOWN DRAFT VENT     An improved driving mechanism for a motor driven retractable down draft vent system of the type having a vent inlet member slidably mounted for vertical movement between lowered position and a raised position.  A first drive member is fixedly connected to a drive motor which drives the first drive member between a first position and a second position corresponding to the lowered and raised positions of the vent member respectively  A second drive member supported from the movable vent inlet member is disposed in the path of the first drive member.  The first drive member abuttingly drivingly engages the second drive member in moving from its first to its second position to positively drive the vent inlet member from its lowered to its raised position.  The second drive member is simply driven by the weight of the vent inlet member to follow the first drive member when it returns from its second to its first position to releasably carry the vent inlet member to its lowered position.  Since there is no positive connection between the first and second drive members, the only force applied to an obstruction blocking the return of the vent inlet member will be the weight of the vent inlet member itself.  Consequently, neither the obstruction, the vent inlet member nor the motor is likely to be damaged.

Title: Process for preparing a microporous membrane and such a membrane
Inventor: ROESINK HENDRIK D W
IPC: B01D67/00
Filed: 1990-04-25
Abstract: Starting from a mixture of at least a hydrophobic polymer and a hydrophilic polymer, these polymers are first dissoved in a suitable solvent or mixture of solvents and subsequently coagulated in a coagulation bath. According to the invention a more or less hydrophilic membrane is prepared by removing the membrane so obtained from the coagulation bath and subsequently by leaching at least a part of the hydrophilic polymer from the matrix, alternatively followed by hydrophobisation. Said leaching of the hydrophilic polymer occurs by treatment of the membrane with an oxidising/hydrolising agent. The invention furthermore comprises microporous membranes, flat or tubular or in the form of hollow fibers, having a good chemical resistance and good mechanical strength.

Patent CA-2017843-A1 (CA)
Inventor: BARON CARL N
IPC: B05C11/10
Filed: 1990-05-30
Abstract: A fluid dispensing apparatus is provided with a controller for modifying a tool speed signal from a robot and to generate a corrected signal to the dispenser nozzle flow controller which compensates for non-linear flow characteristics of fluids, such as non-Newtonian adhesive fluids, to maintain uniform bead size as the tool speed varies.  The corrected tool speed signal is generated by computing the ideal flow for the tool speed signaled, comparing the computed flow with actual flow data stored in a memory using linear interpolation of data between the stored values, and generating a control signal modified in accordance with the comparison.  The stored data is acquired by operation in a calibration mode wherein a series of standard signals is sent to the fluid controller while the actual flow at each signal level is measured and stored in a table.  The method of operation corrects non-linear flow phenomena such as the shear-thinning effect.

Abstract: In an asynchronous transfer mode (ATM) switching system, an N-byte ATM cell containing a header and user data is received from a line circuit and an N-bit header containing routing information is derived from the received header. The received ATM cell is converted into a sequence of N parallel data bits and supplied to a first-stage controller to generate a first switching control signal. A successive bit of the N-bit header of the ATM cell is switched through a first-stage header-transfer switch in response to the first switching control signal and successive N parallel data bits of the cell are switched through a first-stage cell-transfer switch in response to the same control signal in synchronism with the first-stage header-transfer switch. A second-stage controller is responsive to the N-bit header switched from the first-stage header-transfer switch for generating a second switching control signal. A second-stage cell-transfer switch switches successive N parallel data bits of the ATM cell supplied from the first-stage cell-transfer switch in response to the second switching control signal. Successive N parallel data bits of the ATM cell supplied from the second-stage cell-transfer switch are converted to serial form for transmission to the next stage or switching system.

Title: Dram cell field architecture having higher-ranking bit switch lines and higher-ranking bit lines
Inventor: LUSTIG BERNHARD
IPC: G11C5/06
Filed: 1991-03-26
Abstract: ABSTRACT OF THE DISCLOSURE    DRAM cell field architecture having higher-ranking bit switch lines and higher-ranking bit lines.  The DRAM cell field architecture has a bit line pair (BLj, BLj+2) which is respectively selected from a plurality of bit line pairs by bit switches (5 through 12) in every individual memory block.  Of the respectively selected bit line pairs, only the bit line pairs of the selected memory block in each memory block are in turn through-connected to the higher-ranking bit lines (IOk through IOk+3). The higher-ranking bit lines can thereby proceed in a single, for example the second, metallization level in common with higher-ranking bit switch lines (CSLk through CSLk+3) that drive the bit switches, this metallization plane being better utilized as a result thereof.  Depending on the required degree of parallelization, evaluators can be eliminated as a result of the higher-ranking bit lines, whereby the advantage of a short access time given moderate power consumption is preserved for individual access.
