Patent CA-2134590-A1 (CA)
Title: Systems and processes for pyrolyzing contaminates on foundry sand and combusting the resulting gas
Inventor: BURY ROLAND P A G
IPC: F23G5/00
Filed: 1994-10-28
Abstract: The invention relates to combusting contaminants on foundry sand in a container (13) rotating about an axis (A) at a particular angle with a particularly placed oxygen-fuel burner (32).  As the container (13) rotates about the axis (A), the oxygen-fuel burner (32) fires a flame and excess oxygen at a particular angle to enhance pyrolysis of the contaminants.  The amount of excess oxygen is such that the resulting off gas contains at least 2% oxygen by volume, thus preventing or substantially minimizing products of incomplete combustion from leaving the container (13).  After having pyrolyzed the contaminants, the firing of a flame and excess oxygen from the oxygen-fuel burner (32) may be replaced with oxidant dispersion at the bottom of the foundry sand. The resulting off gas from the container (13) may be treated in a post combustion furnace (7), a flue gas cooling means (8), a filtering device (9) and/or a pollutant removing means (11).

Title: Transponder system
Inventor: WESTMAN TONY
IPC: G01S13/74
Filed: 1993-05-10
Abstract: The transponder system according to the present invention presents a light weight portable or mobile system for localization of movable objects, e.g., for surveillance of valuable transports and the like. The small unit constituting the transponder contains a receiver (I) of paging type, a decoder (2), a logic unit (3), a transmitter portion (10), a built-in antenna and power supply (11). Additionally the system is further controllable by means of an existing tested radio system for paging. The advantages of utilizing an already existing paging system owes for one part to the fact that functionality is well tested at the same time as a general covering range its obtained and further that costs for building up and operation of this are eliminated. Control information being sent to the transponder is comprising first a number of symbols defining a certain basic function for the built-in marker transmitter (10) while the remaining symbols further are constituting control code and control data for this specific fraction, consequently at least the frequency, transmit power and transmitting sequences of the marker transmitter are controllable.

Patent CA-2142890-A1 (CA)
Title: Personal number communications system
Inventor: YUE DRINA C
IPC: H04W4/00
Filed: 1993-08-24
Abstract: A personal number communication system assigns a personal number to each subscriber, and receives from each subscriber communication routing information in the form of one or more hierarchical lists of destinations based on the time of day and day of the week. The hierarchy and composition of the lists may be changed or may be overridden to direct selected communications to a specific destination.  The system receives communications directed to a subscriber's personal number and identifies the source of the communication. The identification may be made through calling line identification, through a personalized list of callers, or through source identification. The system selects a first destination for the communication from the hierarchical list. At the first destination, the system announces the identified source of the communication and requests disposition information as to the acceptance, formal rejection or passive rejection, such as a no answer, of the communication. If accepted, the system routes the communication to the first destination. If rejected, the system routes the communication to the default destination selected by the subscriber. If there is a passive rejection, the system requests communication disposition information from the next destination in the destination list according to the hierarchy selected by the subscriber. The system continues to request communication disposition information from each sequential destination on the destination list until the communication is accepted or until the last destination on the destination list is reached, at which point the communication is routed to the last destination.

Title: Ball propelling machine
Inventor: ELBAUM DANIEL
IPC: A63B69/40
Filed: 1992-11-13
Abstract: A machine which can be used by a player practising a ball game such as tennis or badminton has an ejection mechanism comprising a pair of revolving discs (1a, 1b) spaced apart by a gap (2) through which can be drawn a ball (4) for ejection in a direction (3) which can be determined by appropriate adjustment of the vertical and horizontal positioning of the revolving discs by means of inclination drive (10) and sweep gear (12). Side spin or slice can be imparted to the ball by rotation of the revolving discs about an axis lying in the direction (3) of the ball ejection, whilst top spin or under spin can be imparted to the ball by varying the angular velocity of the discs (1a, 1b) by causing them to rotate at differing speeds. The ejection mechanism may be mounted on a height adjusting mechanism in order to vary the height at which the ball is ejected. The machine can be controlled by a microprocessor-based system which may be pre-programmed or operated by remote control.

Abstract: An immobilizing clamp for engaging the wheel of a vehicle comprises a pair of flat plates coupled together by a pivot pin so that the surfaces of the plates slide one on the other. The plates define a base portion which is generally rectangular and a single arm extending from the base portion. The base portion has a pivot pin and a lock with the lock and pivot pin lying generally on a line symmetrical of the two clamping members and passing through end points at the ends of the arms. The height and width of the base portion is so that there is significant overlap which provides sufficient strength to prevent leverage against the clamping members from forcing the end points of the arms apart either in the common plane or at right angles to the common plane.
