Title: Method and mobile filing station for gas filling process of insulating glass windows
Inventor: DOBOS IOAN
IPC: E06B3/677
Filed: 1994-10-18
Abstract: A method and mobile filling station for filling of insulating glass (IG) units is designed to be simple, reliable, low in cost, flexible in operation, improving the productivity of filling process and decreasing the number of IG units destroyed during the filling process. The mobile filling station is built-up as a system of independent modules, each module being used for filling of an IG unit. Each module includes a filling gas detector able to detect the presence of any filling gas used in IG units filling process, a control system of the filling process and a monitoring system of the main parameters of the filling process, being used for any filling gas and any number or dimensions of IG units to be filled-up independently and at the same time. To eliminate damages of the IG units due to of a difference between the pressure of inner space of the IG unit and the atmospheric pressure, the inner pressure of the IG unit, during the filling process, is maintained equal to the atmospheric pressure or, if necessary, corrected to compensate the difference of the two pressures due to the altitudes of the future location of the IG unit. The mobile filling station has an ergonomic construction and like this the operational time and effort are reduced. Since the entire process is fully automatic no trained personnel is needed. The insulated glass units are not manipulated during the filling process. The modules to control the filling process are concentrated in a mobile filling station

Abstract: MULTIPLE EXECUTION UNIT DISPATCH   WITH INSTRUCTION DEPENDENCY                          Abstract A multiple execution unit processing system is provided wherein each execution unit has an associated instruction buffer and all instruction are executed in order.  The first execution unit  (unit  0)  will  always  contain  the  oldest instruction  and  the  second  unit  (unit 1)  the  newest. Processor instructions, such as load, store, add and the like are provided to each of the instruction buffers (0,1) from an instruction cache buffer.  The first instruction (oldest) is placed in buffer 0 and the next (second) instruction is stored in buffer 1.  It is determined during the decode stage whether the instructions are dependent on an immediately preceding instruction.   If both instructions are independent of other instructions, then they can execute in parallel.  However, if the  second  instruction  is  dependent  on  the first,  then (subsequent to the first instruction being executed) it is laterally  shifted  to  the   first   instruction  buffer. Instructions  are  also  defined  as being  dependent  on  an unavailable  resource.  In  most  cases  these  "unavailable" instructions are allowed to executed in parallel on the execution units.

Patent CA-2132061-A1 (CA)
Title: Synchronization circuit for visual/audio alarms
Inventor: KOSICH JOSEPH
IPC: H05B41/34
Filed: 1994-09-14
Abstract: A strobe alarm system which includes multiple normally self-timed strobe circuits connected in a common loop to a fire alarm control panel, and a sync control circuit, which may be incorporated in the fire alarm control panel, for causing the strobes to flash in synchronism at a predetermined rate which will insure that a person viewing the multiple strobes would not see dash rates higher than the predetermined synchronized rate, which is preferably less than five flashes per second. The sync control circuit does not interfere with the supervision functions of the alarm system, and when an alarm condition is present it supplies power to the strobe circuits which it then interrupts once every flash cycle to cause a sync trigger circuit in each strobe to fire its flashtube, and to reset the internal timer of each strobe to ready it for arrival of the next sync signal. Each strobe circuit in the loop includes a resettable timer for recycling its own flash unit in a non-synchronous fail-safe mode in case the sync signal should fail to appear within a finite period following the last previous flash. That is, normally the strobes are all fired at the same time in response to sync signals applied to their sync trigger circuits, but in the event the sync signal is lacking the strobes will continue to flash, each at a rate determined by its internal timer.

Title: Methods and apparatus for facilitating a measurement taken from a vehicle wheel axis
Inventor: SCHMIDT GEORGE R JR
IPC: G01B5/00
Filed: 1994-10-31
Abstract: In order to check a vehicle for sagged coil springs, vertical distances are measured between the axis of each wheel and a predetermined location on the vehicle body, e.g., the underside of the fender. Those measured distances axe compared with established values for that vehicle make and model. To facilitate that measurement a tool is elastically bent arid the ends of the tool are mounted by friction-fit against the inside periphery of a wheel rim. The bent tool forms a convex bulge, the apex of which is aligned with the wheel axis and is disposed in or near a vertical plane in which the measurement is to be made. A reference mark provided at the apex of the bulge facilitates a measurement with a ruled tape measure.
