Abstract: HIGH IMPACT POLYSTYRENE HAVING IMPROVED                 GLOSS AND IMPACT CHARACTERISTICS                      ABSTRACT OF THE INVENTION    A composition and process for making it are disclosed which teach  multimodal  particle  size  high  impact  monovinylaromatic polymer material having good gloss properties as well as high impact strength.  The bimodal particle size rubber component of the material utilizes a small amount of a very large particle size rubber and a large amount of a very small particle size rubber.          The unique and advantageous method of manufacturing the material involves introducing pre-existing pellets of a rubber/polymer blend into a monomer solution also containing a  rubber capable  of producing particles of a different range of sizes than that of the rubber  component   in  the  pellets,   and  polymerizing  the monomer/dissolved pellet mixture into a multimodal particle size high impact material.
Patent CA-2122067-A1 (CA)
Inventor: CAMPAS JEAN-JACQUES
IPC: B21C51/00
Filed: 1994-04-25
Abstract: The device is intended for the calibration of a system for measuring the thickness profile of flat products, for example metal sheets, which includes a radiation source (10), for example an X-ray source, and a row (20) of elementary detectors (21) aligned in the direction (P) of the profile to be measured, these being placed on either side of a zone (2) through which the said product passes. The device includes a set (32) of shims (33) having different characteristics, and a carriage (30) for supporting the shims which move in this direction. In order to carry out the calibration, the set of shims is moved in the passage zone so that each shim can intercept the radiation emitted by the source in the direction of each detector and, as the carriage moves, several readings are made of the signals emitted by the detectors so as to obtain, for each detector, a set of values of the signals representative of the intensity of the radiation absorbed by each shim, and, from these values, the calibration curve of each sensor is obtained. <IMAGE>

Title: Dynamically specifying invocations in compiled objects
Inventor: ANDERSON JOHN S
IPC: G06F3/0487
Filed: 1994-11-22
Abstract: Apparatus for specifying invocations in compiled objects at runtime. The apparatus is embodied in a drawing widget for use in the X Window System. The drawing widget permits users to specify elements in the window corresponding to the widget by providing a sequence of invocations of X Window graphics functions to the widget at runtime. A resource in the drawing widget is set to the sequence of invocations and when the corresponding window is exposed, the invocations in thesequence are executed to produce the elements in the window. The sequence of function invocations may include invocations for functions which add or remove elements from the window and which translate, rotate, or scale elements. Other features include the use of unit coordinates in the invocation and the use of hashing to reduce the character-string invocations provided in the sequence to representations made up of small integer, pointer, and floating-point data.

Inventor: BAUER FRED P
IPC: H01R33/08
Filed: 1995-04-10
Abstract: One half-connector terminates a set of leads in the bal-last for carrying electrical power to and from the ballast coils.  Another half-connector terminates another set of leads outside the ballast, connected e. g. to carry power to lamp sockets.  Male contacts, preferably formed very inexpensively as bared ends of one set of leads, are held in a first of the half-connectors; female contacts, connected to the other set of leads, are held in a second of the two half-connectors.          Through-holes in the second half-connector each hold one fe-male contact; each hole has a necked-down section, forward from the contact, and some device (preferably an ultrasonical-ly displaced slug) to retain the contact.  In one aspect of the invention, each hole also has a bore whose transverse preformed dimension is biggest immediately rearward from the necked-down forward section.  In a second aspect of the inven-tion, each necked-down section has a large-mouthed funnel to guide even a badly bent male contact into the female contact, accommodating weak tips of the bared wire ends.  The first aspect of the invention enables low-cost use of the second.

Patent CA-2151682-A1 (CA)
Title: Signal detection device and clock recovery device using the same
Inventor: OHMI SHINICHIRO
IPC: H04L7/00
Filed: 1995-06-13
Abstract: A time window detection portion 3a outputs a time window detection pulse from a time window signal generated in a time window generating portion 2a and a zero-cross detection pulse detected in a zero-cross detection portion 1a.  First and second phase storage portions 4a and 5a store output phase values of a phase counter 22 for different times as first and second phase values, respectively.   A center phase computing portion 6a computes a first center phase value from the first and second phase values and a center phase storage portion 7a stores the first center phase value of the last time as a second center phase value.  An approximation detection portion 8a determines whether the first and second center phase values are approximate or not and outputs an approximation detection pulse when they approximate.  A frequency determination portion 20 determines whether a data signal is included in the input signal or not on the basis of frequency of detection of the approximation detection pulse with respect to the zero-cross detection pulse computed in a frequency computing portion 17.  A mean phase computing portion 18 computes a mean phase value from the first center phase value, and a phase correction portion 19 computes a correction phase value from the output phase value of the phase counter 22.  A setting portion 21 sets one of the mean phase value, a steady phase value and the correction phase value as an initial phase in the phase counter 22 in accor-dance with the  result of determination by the  frequency determination portion 20.   A clock generating portion 23 generates clocks on the basis of the output phase value of the phase counter 22.
