Title: Railway Freight Brake Retainer Valve Device
Inventor: STAHMER ULF
IPC: B60T15/54
Filed: 1993-02-25
Abstract: A brake cylinder pressure retainer valve device for a railway car having a "direct" exhaust position, a "slow direct" exhaust position, and a "high pressure" retention position.   A cavity in the retainer valve body has a central pedestal on which a rotary type disc valve is mounted.   The disc valve has different sized ports via which pressure is connected from an inlet port (in the retainer valve body) to an outlet port depending upon the position of a manually operated handle to which the disc valve is connected.   One such port is associated with a spring loaded check valve to provide the "high pressure" retention of the brake cylinder  exhaust pressure.   A laterally flexible sidewall of the disc valve member is formed with 180° opposed detent tabs for engagement with a plurality of detent grooves formed in the sidewall of the valve  body  within  which  the  disc  valve  is  operably disposed, the detent grooves being positioned to receive the detent tabs in accordance with the respective openings in the disc valve for alignment thereof with the inlet port in the different brake cylinder exhaust control positions.          Plastic is the material of choice for this brake cylinder pressure retainer valve device.

Title: Spacer assembly and method
Inventor: PIENAAR FRANS R P
IPC: E21D15/48
Filed: 1993-08-09
Abstract: ABSTRACT            The invention concerns a method and apparatus for providing yielding support for a hanging wall above a footwall in a mine working. A support assembly is installed between the hanging wall and the footwall, the assembly including a spacer (10), a pack (30) and a grout-inflatable bag (32). Grout is pumped into the bag (32) and is allowed to set to apply a vertical prestess force to the support assembly. The spacer (10) is substantially stiffer in compression than the pack (30), which is designed to yield under the compressive loading applied by the hanging wall. The use of a stiff spacer (10) serves to elevate the yielding pack to a suitble operative height without the allowable slenderness ratio for the pack to be exceeded.

Title: System and method for peripheral data transfer
Inventor: VOTH DAVID W
IPC: G06F13/42
Filed: 1993-12-10
Abstract: SYSTEM AND METHOD FOR PERIPHERAL DATA TRANSFER     Abstract of the Disclosure A system and method for increasing the rate of data transfer from a host computer to a peripheral such as a printer without the need for special hardware within the host computer or a special interface cable coupling the host computer to theperipheral. Data is transferred from the host computer to the peripheral in 4 Kbyte bursts. Handshaking occurs between the host computer and the peripheral only between bursts. Bytes of peripheral data are apportioned into multiple bytes of data within the host computer. The multiple bytes are transmitted from the host computer to the peripheral, each transmitted byte containing a data clock and several bits of peripheral data. In one embodiment, the peripheral data byte is apportioned into two bytes within the host computer with each byte having a pair of clock signals transmitted along with the peripheral data portion. In another embodiment, threebytes of peripheral data are apportioned into four bytes within the host computer with each byte having a single clock signal transmitted along with the peripheral data portion. Within the peripheral, a clock circuit detects the clock signal from each transmitted byte and generates a delayed signal to latch peripheral data bytes into a storage register. In addition, the first transmitted byte contains a flag to signal the peripheral that the data that follows is RLE compressed data. Parity bits are also included in the transmitted data. The system can be easily implemented on any Centronics compatible printer system to increase the rate of data transfer.

Patent CA-2117797-A1 (CA)
Inventor: KOTZIN MICHAEL D
IPC: H04L27/00
Filed: 1994-02-07
Abstract: A method and apparatus are provided for receiving electromagnetic radiation within a frequency band. The receiving is accomplished by intercepting electromagnetic radiation within the frequency band and converting the intercepted electromagnetic radiation into an electrical signal (102). Subsequently, a portion of the electrical signal (102) is digitized (104) into digitized signals (112, 113, 114). Each digitized signal (112, 113, 114) represents the intercepted electromagnetic radiation within a portion of the frequency band. Finally, a composite digitized signal (118) is generated (116) from at least two of the digitized signals (112, 113) 114). Alternatively, the receiving process may be enhanced by intercepting (188) first electromagnetic radiation (192) within a portion of the frequency band and by intercepting (190) second electromagnetic radiation (194) within another portion of the frequency band. Subsequently, the first and the second electromagnetic radiation (192, 194) is combined (196) into a composite electromagnetic radiation waveform (198). The composite electromagnetic radiation waveform (198) is converted into an electrical signal which may be processed (204) into digitized signals (206, 208) which form a composite digitized signal (118).

Title: Extended lifetime collimator
Inventor: HURWITT STEVEN D
IPC: C23C14/34
Filed: 1992-12-29
Abstract: An improved, extended lifetime collimator (11) for cathode sputtering has a plurality of passages (20) which taper longitudinally from a target (13) side of the collimator to a wafer (14) side of the collimator. This longitudinal tapering reduces the adverse effects on collimator useful life and wafer deposition rate which are generally caused by the accumulation of sputtered particles on exposed surfaces on the target side of the collimator (11).  Compared to prior collimators, this collimator (11) may be used to sputter coat a greater number of wafers (14) before replacement or cleaning is necessary, thereby enhancing throughput capability.

Title: Error Tracking Loop
Inventor: HORWITZ THOMAS P
IPC: H04L1/00
Filed: 1994-01-11
Abstract: A circuit for correcting errors in a received complex data signal including a synchronous detector for recovering an in-phase data component from the received signal and a Hilbert transform filter for estimating the related quadrature component from the recovered in-phase data component, the recovered in-phase data component including a periodically recurring reference signal. A decision feedback loop is periodically operable in response to the reference signal for initially error correcting a selected characteristic of the received signal at a first relatively rapid rate and for subsequently error correcting the selected characteristic at a rate which is less than the first rate and which is dependent upon the estimated signal to noise ratio of the received signal. In one embodiment, phase errors are corrected at a rate which is also directly related to the value of the estimated quadrature component.      In another embodiment, amplitude errors, e.g. gain and offset, are corrected at a rate which is inversely related to the value of the estimated quadrature component.
