Patent CA-2186626-A1 (CA)
Title: A data processing system for use in communications pricing and charging equipment and a production process therefor
Inventor: FREESTONE DAVID
IPC: H04M15/00
Filed: 1995-03-30
Abstract: It is important, as the communications environment grows increasingly complex, that it is possible to convert chargeable events into billable values in a flexible manner. In particular, it is important that the pricing and charging arrangements available to network operators or service providers can take account of factors such as taxes which affect the billable value and which may be put in place in many different ways and at variable times in relation to data processing exercises which need to be carried out. A system is therefore provided which can be used in generating bills by applying modifying factors which can be changed or added to in a relatively easy manner. A preferred version of the invention provides an object-oriented front end for a legacy system, which front end can be used in design and subsequently embedded. Programs developed in an object oriented environment are converted intoinstructions implementable by a procedurally based processing device. An activity hierarchy of functions is created for each object, a data subject area is created for each object and a main calling program specifies the relationship between the programs and data areas so as to retain the encapsulation of the original object oriented definition. This aspect of the invention is particularly useful for developing new systems in an object oriented environment which may then be embedded into existing procedurally based systems.

Patent CA-2198652-A1 (CA)
Inventor: CRAMER ROBERT LOUIS
IPC: A61M16/00
Filed: 1997-02-27
Abstract: A control means for molecular sieve on-board oxygen generating systems measures both temperature and pressure of the inlet air of an oxygen generating system. An electronic control unit applies pressure limits to a pressure measurement signal and combines it with a temperature measurement signal to produce a composite analog signal responsive to both temperature and pressure inlet air conditions. This analog signal is linearly converted to a frequency signal whereupon the frequency signal is divided by a constant in order to produce a drive signal for control of the absorb/vent bed cycle valves. Composition control is achieved by venting product mixture as required. Inlet air pressures down to 5 PSIG (pounds per square inch gauge) produce correct system operation and the quantity of conditioned air required is automatically limited so that system efficiency is higher than prior art systems.

Title: Reinforced refrigerator door assembly and method of assembling the same
Inventor: POHL DOUGLAS A
IPC: F25D23/02
Filed: 1997-03-11
Abstract: A pair of cross brace members are diagonally positioned within an internal cavity of a refrigerator door shell that is defined by an outer front panel, side walls and in-turned, return flanges. The cross brace members are generally L-shaped in cross-section and are inter engaged at central portions thereof which are specifically configured with respective cut-out connection portions to aid in assembly and positioning of the cross brace members. The cross brace members have tabs at terminal ends thereof which extend above planes defined by generally horizontally extending upper sections of the cross brace members. These tabs are adapted to rest upon respective ones of the return flanges to initially mount the cross brace members within the door shell. Once the cross brace members are appropriately positioned with the door shell, insulation foam is supplied into the internal cavity. The foam flows through longitudinally spaced holes provided in generally upright sections of the cross brace members and around the cross brace members. Once the insulation foam hardens, the cross brace members become fixed to the door shell such that a reinforced refrigerator door assembly is defined. An inner door liner can then be attached to the return flanges.

Title: Method and apparatus for delivering a cased glass stream
Inventor: SCOTT GARRETT L
IPC: C03B17/02
Filed: 1997-09-08
Abstract: Apparatus for forming a cased glass stream having an inner core glass surrounded by an outer casing glass includes a first orifice for receiving core glass from a first source. A second orifice is vertically spaced beneath and aligned with the first orifice, and is surrounded by an annular chamber that communicates with the second orifice through the gap between the first and second orifices. A spout delivers casing glass from a second source through a tube to the annular chamber in such a way that glass flows by gravity from the first and second sources through the orifices to form the cased glass stream. A  plurality of gas burners are disposed in the spout above the glass pool. The casing glass delivery spout is configured for improved heat transfer to, and improved heat retention within, the casing glass pool within the spout. Specifically, the glass pool surface area is enlarged, and the glass pool depth is reduced. Free space above the glass pool is enlarged to accommodate gas flames from more burners, and to increase surface heat radiation into the glass pool. The housing that supports the spout is designed such that an annular spout support surface engages the spout radially outwardly of the spout opening(s) for reducing heat transfer to the housing from casing glass flowing through the opening.

Title: Sticky bit determination in floating point arithmetic system
Inventor: KAWAGUCHI TADAHARU
IPC: G06F7/509
Filed: 1997-09-18
Abstract: A system determines a sticky bit in a floating point arithmetic system without performing a logical sum of bits shifted out after alignment. The system compares exponents of input operands representing floating-point numbers, and subtracts smaller exponent from larger exponent to determine a shift amount by which the smaller mantissa is to be shifted for alignment. The system generates a shift signal indicative of the determined shift amount. The system counts the number of leading zero in mantissa of the smaller exponent toward the most significant bit of the mantissa, and generates a leading zero count signal indicative of the counted number of leading zero. The system compares the shift signal with the leading zero count signal and generates a sticky bit signal in response to the result of comparing the shift signal with the leading zero count signal, which sticky bit signal anticipates creation of a sticky bit after shifting the mantissa for alignment.
