Title: Vital rate decoder
Inventor: RUTHERFORD DAVID B
IPC: G06F11/00
Filed: 1989-10-20
Granted: 1999-12-07
Abstract: A vital microprocessor-based rate decoder for use in a vital processing system in on-board main line railroad and rapid transit automatic train protection systems; the design is such that a method is incorporated for tolerating specific kinds of signal disruption and in such a way that the probability of a wrongside failure has a calculable upper bound. A pickup coil transmits external or wayside signals to an arrangement which involves two channels and which provides period and duty cycle measurement of the pulses resulting from demodulation of the external signals. A counter is employed in each of the channels and a tolerance accumulation rate decoding device is included, the maximum amount of tolerance accumulated, and the minimum time required to accumulate it, being functions of the rate code selected.
Patent CA-2001084-C (CA)
Inventor: ALMBLAD ROBERT
IPC: B23C3/35
Filed: 1989-10-20
Granted: 1997-05-06
Abstract: First and second cutter head assemblies each include a key follower positioned at a first elevation and a spaced apart cutting wheel positioned at a second elevation.  The key followers trace the bitted surfaces of a master key while the cutting wheels move with the key followers and duplicate bitted surfaces of the master key onto a key blank.  A linear displacement bearing assembly is coupled to the first and second cutter heads to permit the key followers and cutting wheels to be laterally displaced with respect to the master key and key blank.          A key positioning cassette system holds and aligns the master key and key blank relative to the first and second cutter head assemblies.  Another linear displacement device is coupled to the base of the key cutting machine and to the cassette system for longitudinally displacing the key blank and the master key with respect to the longitudinally fixed key followers and cutting wheels.  The various elements of the key cutting machine thus trace or follow the bitted surfaces of the master key and duplicate those bitted surfaces onto the bitted surfaces of the key blank.

Title: Whipstock starter mill with pressure drop tattletale
Inventor: BAILEY THOMAS F
IPC: E21B47/18
Filed: 1990-01-10
Granted: 1995-12-19
Abstract: A whipstock mill for milling through the casing wall which incorporates a pressure drop tattletale to signal the operator that the milling operation should be halted.  The milling tool includes a longitudnal  fluid passageway which communicates with a lateral port formed below the mill blades. A replaceable plug is utilized to initially close the port thereby restricting fluid flow into the well hole.  The start-er mill is preferably run into the hole with a whipstock which can be set in the hole using an integral packer.  As the mill travels down the set whipstock, a shear block mounted to the whipstock will shear the plug at a predetermined depth of the mill opening the lateral port.  The resulting pressure drop within the milling tool signifies that the mill has reached the desired depth.  Accordingly, the milling operation can be halted and the mill retrieved to permit further operations through the casing wall.

Title: Vehicle seat for a child
Inventor: KNOEDLER ROY E
IPC: B60N2/28
Filed: 1990-02-22
Granted: 2000-02-08
Abstract: A child's car seat is provided that includes a seat belt assembly and a shield assembly. The seat belt assembly includes a seat belt that engages the lap of the child. A vehicle seat belt retains the car seat at the back of the vehicle seat. The seat belt of the child's car seat remains fixed in position once the child is secured in position. As a result, the child cannot extend the length of the seat belt and defeat its restraining purpose. The shield assembly can be positioned on either of two different sides to facilitate seating/unseating of the child in/from the car seat. The shield assembly can be removed whereby remaining portions of the car seat can be used with a vehicle lap belt to support and restrain the child.

Granted: 1994-09-13
Abstract: A  color signal emphasizing/de-emphasizing  method  and apparatus  for  outputting image data scanned from  the  target image  in  every pixel on a color print or a color  display  by means  of  three  principle color signals.   These  method  and apparatus  are  intended to obtain a desired hue  variation  or color saturation by emphasizing/de-emphasizing one of the three principle  color  signals.   The  three  principle  colors  are classified  into  a primary color portion signal,  a  secondary color portion signal and tertiary color portion signal.   These designated   signals   of  color  portions   are   respectively multiplied   by  color  coefficients  predetermined  for   each designated  signal.   Finally,  a  corrected  color  signal  is obtained  by  summing up these  multiplied  signals  in  every principle color.

Title: Spring-applied, hydraulically released brake actuator having positive clearance slack adjuster mechanism
Inventor: TA CUONG MANH
IPC: F16D65/56
Filed: 1991-07-26
Granted: 2002-06-11
Abstract: A spring-applied, hydraulic pressure released brake actuator having a modular slack adjuster assembly in which a friction ring is arranged to limit axial movement of a nut member to which a brake shoe is connected, thereby establishing a predetermined brake shoe clearance with a vehicle wheel or brake disc. A spindle that is threadedly engaged with the nut member is connected to the actuator piston by means of a cone clutch that is disengaged during a brake release in the event the return stroke of the piston exceeds the predetermined brake shoe clearance due to brake shoe wear during the preceding brake application.      This disengagement of the clutch causes the spindle to be rotated relative to the nut member under the influence of a slack adjuster spring in order to compensate the piston overtravel.

Granted: 1999-01-19
Abstract: A received time division multiple access (TDMA) signal having a time  slot comprised of a plurality of symbols including at least one sequence of synchronizing symbols and a plurality of data symbols is demodulated by adaptively filtering  the  received  signal  to minimize  inter-symbol interference due to an effect of channel signal propagation delay.

A metric is next formed for each of the stages in accordance with a predetermined mathematical relationship between the output signals of each of two stages. A plurality of the formed metrics are next accumulated over a plurality of time slots. A number of stages are then recursively determined for the lattice decision feedback equalizer for use during the next time slot by comparing, to a threshold value, the difference between the values of two accumulated metrics.
