Patent CA-2116216-A1 (CA)
Title: Rail thermal treatment process
Inventor: MOSER ALFRED
IPC: C21D9/04
Filed: 1993-07-09
Abstract: A method for the thermal treatment of rails, in particular of the rail head, in which cooling is carried out in a cooling agent that contains a synthetic cooling agent additive, and starting at temperatures above 720°C. The treatment is carried out by immersion in the cooling agent until withdrawal of the immersed areas occurs, at a surface temperature between 450 and 550°C which results without temperature equalization across the entire cross-section, thereby avoiding hardening of the rail web whilst maintaining an optimal cooling rate for the rail head.

Title: Enhanced monitoring device for surgical barriers
Inventor: WILLIAMS ROBERT E
IPC: G01N27/20
Filed: 1993-03-03
Abstract: A monitoring device for detecting adulteration of an article used in critical use applications such as a surgical glove where the gloves are worn by the surgeon and are exposed to the body fluids of a patient. The device includes the detection of a particular value of electrical condition, preferably resistance or impedance, as well as the first and second derivatives of electrical condition. These values are monitored in a substantially continuous manner and are smoothed and filtered to determine when a hole or thin spot in the glove occurs. In addition, the device includes an autoranging function which maintains the measured voltage in a prescribed range, thus allowing the device to operate at a higher level of accuracy for a greater period of time than a device with-out the feature. Also, the device warns the health care professional when the electrical properties of the gloves have degraded to a point where the device may no longer reliably detect holes in the gloves.

Title: Method and system for data compression
Inventor: SLIVKA BENJAMIN W
IPC: G06F3/06
Filed: 1994-03-11
Abstract: METHOD AND SYSTEM FOR DATA COMPRESSION   Abstract of the Disclosure A method and system for compressing a  stream of bytes in a compression system.   The compression system has a search data structure containing slots  for identifying the position of occurrences of byte sequences in an input stream. A byte  sequence  is  retrieved from the  input  stream.   The method  then  determines  whether  the  search  data  structure contains a slot identifying the position of a byte sequence that matches the retrieved byte sequence.  If the search data structure contains a slot which identifies a matching byte sequence,  then the contents of a search data structure slot containing the match is replaced with the position of the retrieved byte sequence.   If the search data structure does not contain a slot identifying a matching byte sequence, then a  slot  is  selected  using  a  least  recently  updated  slot algorithm.   The contents of this least recently updated slot are then replaced with the position of the retrieved byte sequence.   When a matching byte sequence is determined,  an indicator  of  the  position  identified  in  the  slot  before replacement  is  output.    If  no  matching  byte  sequence  is determined,  then a byte of  the retrieved byte sequence  is output.

Title: Red data detector for picture data compression device
Inventor: SUGISAKI KIMINORI
IPC: H04N19/14
Filed: 1994-09-02
Abstract: A picture data compressing device includes blocking, shuffling, DCT, quantization, variable length coding circuits, as well as a red block detector and a controller. The picture data are divided in blocks containing a pre-set number of pixels. The red block detector performs block-by-block processing by comparing the red-hued data and the blue-hued data with preselected red and blue threshold values for identifying blocks of data with red-hued pixels. The controller adjusts the quantization step size according to pre-established classes such that a finer quantization step is used when a red block is detected. By reducing the number of the red blocks, the block distortion is decreased and the picture quality is improved. Identification of the red picture data based on examining both red-hued and blue-hued data increases the detection accuracy. If the red and blue threshold values are selected as a multiple of some power of 2, the number of bits necessary for accurately identifying a red block is reduced, while the block-by-block processing requires less counter stages, thus simplifying the hardware and lowering the cost.

Abstract: A modular measurement while drilling sensor assembly is presented. A typical cross-over assembly for mating with a measurement while drilling (MWD) tool is connected to a typical positive displacement mud motor (e.g., a Moineau motor). A modular sensor assembly comprises two portions, an upper drive shaft portion which includes a flexible shaft connected to the motor and a lower sensor portion and supported by a radial bearing. The lower end of the flexible shaft is connected to a hollowed shaft which extends beyond the lower end of the upper drive shaft portion and which is supported by a radial bearing. The lower sensor portion has a central channel extending longitudinally therethrough, with the lower portion of the hollowed shaft extending through this channel. The sensor portion may comprise any type of MWD sensor, however the present invention is preferably used with sensors (e.g., formation evaluation sensors) that benefit from obtaining measurements close to the bit.  The lower end of the hollowed shaft is supported with a radial bearing and connected to a flexible shaft of an adjustable kick off assembly connected to the sensor portion. The adjustable kick off assembly allows the introduction of a kick off angle, generally between 0° and 3°, in the assembly. The adjustable kick off assembly is connected to a typical bearing pack assembly. The lower end of the bearing pack assembly is typically connected to a drive shaft, a bit box and then the bit.
