Title: Spark plug with integral retainer nut
Inventor: BELOW MATTHEW B
IPC: H01T13/32
Filed: 1997-02-03
Abstract: A spark plug (11) having a center conductive path (21) with a cylindrical body having a tip (33, 51, 77) at one end and a terminal (23) near the other end has an insulator (41, 45) radially surrounding the center electrode and a substantially cylindrical body with at least first and second diameter sections separated by a shoulder (29). A ground shield (37) surrounds the insulator first diameter section and including near one end a frustoconical section (31) juxtaposed with the insulator shoulder. There is a ground electrode (55, 57, 73) near the other end having a portion thereof (53, 75) aligned with the center electrode tip to form a spark gap. An annular retainer (59) surrounds the insulator second diameter section and including a threaded portion (61) threadedly engaging the threaded portion (17) of a generally cylindrical opening in the head of an internal combustion engine. The retainer includes a frustoconical portion (63) overlapping the ground shield frustoconical section and juxtaposed insulator shoulder securing the ground shield and retainer together with the insulator captured therebetween. The annular retainer has a sidewall thickness in the region of the threaded portion which is substantially greater than the sidewall thickness in the region overlapping the ground shield.

IPC: C07C381/10
Filed: 1997-11-13
Abstract: N-arylsulfilimine compounds, such as S,S-dimethyl-N-(2,6-dichlorophenyl)sulfilimine, were prepared and found to catalyze the re-action of aromatic sulfonyl chloride compounds, such as 2-chlorosulfonyl-7-fluoro-5-ethoxy[1,2,4]-triazolo[1,5-c]pyrimidine, with aromatic amine compounds, such as 2,6-dichloroaniline, to form N-arylarylsulfonamide compounds, such as N-(2,6-dichlorophenyl)-7-fluoro-5-ethoxy-[1,2,4]triazolo[1,5-c]pyrimidine-2-sulfonamide. The aryl moiety of the N-arylsulfilimine catalyst and the aryl moiety of the aromatic amine compound were generally chosen to be identical.
Patent CA-2245026-A1 (CA)
Inventor: MEYER ERICH NICOL
IPC: F42D1/055
Filed: 1998-08-12
Abstract: A method and system for causing a multi-shot blast is disclosed and claimed. According to the method, suitable positions for detonators 14.1 to 14.8 are determined in situ. Position related data (x;y) is determined automatically for each position utilizing a GPS system and also identification cods data of each detonator. This data is transferred to a controller 16 via a data-capturing device 18. The controller establishes a blast programme including inter hole delay times calculated by taking into account the position related data, geological structure, hole depth, mass of explosive in hole etc. The controller transmits signals including delay time data to the detonators, to cause them to detonat~ according to the programme.

Patent CA-2252119-A1 (CA)
Title: Adjustable height load bearing support structure
Inventor: WEINSCHENK LAVERN L JR
IPC: A47B9/02
Filed: 1997-04-10
Abstract: A height adjustable load support structure (20) has a base frame (22), and a generally planar support surface (32). Preferably, two extendable vertical support assemblies (26) support the surface (32) for vertical movement relative to the base frame (22). Each support assembly (26) is engaged by a spring biased pivotable arm (42) to counterbalance the weight placed on the surface (32). A cam system (44, 46) cooperating between the distal ends of the pivotable arms (42) and the support assemblies (26) serves to compensate for the changing spring force on the arms by varying the effective moment arms of the arms (42) thereby equalizing the force on each support assembly through its complete range of vertical travel.
Patent CA-2253508-A1 (CA)
Title: A method and device for temperature dependent current generation
Inventor: TAN NIANXIONG
IPC: G05F3/26
Filed: 1997-04-29
Abstract: Most temperature related reference generations are in the voltage domain, which means that reference voltages rather than reference currents are generated. In some applications such as driving laser diodes, currents are needed rather than voltages. In the present invention, as an alternative, the references are designed in the current domain, wherein the operation philosophy can be said to be inverse to the operation philosophy of the prior art. The temperature dependence of the currents are known and the currents (1, 2) will be processed by linear and/or non linear operation to generate currents (3) with predetermined temperature coefficients. The advantages of the invention can be outlined as more straightforward, scaling and summation (subtraction) are much easier and simpler in the current domain than in the voltage domain.
