Title: Zincate-Treated Article of Al-Mg-Si Base Alloy and Method of Manufacturing the Same
Inventor: MAEZONO SHUNICHIRO
IPC: C22C21/00

Abstract: A zincate-treated article of an Al-Mg-Si base alloy has a zincate coating film having a Zn crystal grain size of 1.0 µm or smaller on an Al-Mg-Si base alloy body having a Cu content of 0.1 to 1.5-weight %. The Zn crystal grain size is preferably equal to or smaller than 0.95 µm. This zincate-treated article can be manufactured by treating an Al-Mg-Si base alloy body having a Cu content of 0.1 to 1.5 weight % in a zincating treatment bath containing 100 to 300 g/l of sodium hydroxide, 5 to 20 g/l of zinc oxide, 2 to 10 g/l of iron chloride, 5 to 20 g/l of Rochelle salt and 50 to 200 ml/l of water glass at a temperature of 20 to 80°C for 5 to 60 seconds. By adjusting the Zn crystal grain size in the zincating treatment in this manner, a zincate-treated article of an Al-Mg-Si base alloy having an excellent adhesion can be acquired even in a single stage zincating treatment.

Patent CA-2176779-A1 (CA)
Title: Line juxtapositioner
Inventor: JOSOFF PETER LARRY
IPC: B21C47/28
Filed: 1996-05-16
Abstract: A line juxtapositioner 100 comprises a generally cylindrical drum 110 for storing a layer of strand material 200 around its exterior surface. The layer is formed by wrapping the strand material in adjacent convolutions around the exterior surface which is energized to move in a direction which is parallel to the central axis 101-101 of the drum. Consequently the strand material, which is in direct contact with the exterior surface, also moves in a direction that is parallel to the central axis and advances from one end of the drum toward the other. The exterior surface of the drum comprises six segments 120-120 which attach to a common support infrastructure. Electromagnets 710, 720, 730 associated with each segment cooperate to impart cyclic movement to the segment which causes objects on the segment surface to move in a direction which is parallel to the central axis of the drum. Strand material enters the drum at one end and exits at the other end when the drum is rotated. Because the line juxtapositioner stores a relatively large quantity of moving strand material in a relatively compact space, it may be mounted in an oven to improve the annealing of copper wire.

Title: Vehicle theft preventer
Inventor: VASSILAKOPULOS BILL
IPC: B60R25/045
Filed: 1996-05-24
Abstract: A theft prevention system for an automobile having a starter motor solenoid, an ignition circuit, an electrically operated fuel control device and a battery, includes a first relay switchable between a normal operating position and a second position and connected to the starter motor solenoid and to the ignition circuit. There is also an activating switch connected to the battery and to the first relay and switchable between on and off positions. In the off position, the first relay moves to a second position at which the automobile will not start because the ignition circuit is disconnected from the starter motor solenoid. Preferably, a second relay is switchable between an operating position and another position and is normally connected to the fuel control device and to the ignition circuit.  There is a mechanism for disconnecting the second relay from the ignition circuit so as to cause the relay to move to said another position, thereby preventing the fuel control device from causing fuel to flow to the engine.

Title: Process for producing bactericidal/fungicidal plastic bodies
Inventor: KRALL THEODORE
IPC: A61L29/00
Filed: 1995-02-01
Abstract: Objects for use in medical application that are produced from plastics required to have an antimicrobially effective content of metals (or metal compounds) can be produced inexpensively by coating a plastic blank in the form of film, granules or fibers with the desired metal (or metal compound) according to the methods used in thin-film technology. The thus obtained intermediate is subsequently comminuted and mixed and, as the starting product for the desired final form, further processed.      As a result, these objects are antimicrobially effective on every area of their surface, i.e. also on internal surfaces.      The amount necessary for full effectiveness of the antimicrobially active substances, which in the case of the subject-matter of this invention are oligodynamically active metals (or metal compounds), is only a small percentage of that necessary when they are introduced into the plastic in the form of powder, which fact results in considerable financial advantages.

The in vivo system of the present invention is particularly but not exclusively useful for screening for antisense, sense or ribozymes constructs or transdominant polypeptides, small peptides or other chemical compounds and which are capable of inhibiting, reducing, altering or otherwise modulating expression of target genes or target genetic sequences or the activity of target gene products of commercial importance such as in the medical, agricultural and industrial fields.
Patent CA-2186273-A1 (CA)
Title: Electrolyte for a secondary cell
Inventor: SHU ZHI X
IPC: H01M10/26
Filed: 1996-09-19
Abstract: A conventional electrolyte for a secondary cell having a carbonaceous anode is comprised of an alkali metal salt  dissolved   in  an  organic  electrolyte  solvent. Intercalation   and   de-intercalation   during   repeated discharge/charge  cycles  of  the  secondary  cell  using  a conventional electrolyte solvent causes continual exposure of  bare  surfaces  of  the  carbonaceous  material  to  the electrolyte,   resulting   in   continual   consumption   of electrolyte in the formation of new passivation films on the bared or partially covered surfaces, adversely affecting the performance and capacity of the cell.   In accordance with the  present  invention,  the  organic  electrolyte  solvent comprises chloroethylene carbonate, propylene carbonate and ethylene carbonate.  The chloroethylene carbonate is capable of forming a very stable passivation film on the anode.  The performance and capacity of the secondary cell is improved substantially by the addition of the halogenated organic solvent.

Title: Transducer having redundant pressure sensors
Inventor: KLAUDER PHILIP R
IPC: G01L9/00
Filed: 1997-02-18
Abstract: A pressure transducer having a reduntant fluid pressure sensor can be used to determine if the pressure transducer needs to be recalibrated. The pressure transducer comprises a fluid pressure sensor for measuring differential pressure. The fluid pressure sensor includes a pair of substantially identical pressure sensors for providing a variable electrical output as a function of a differential fluid pressure and a reference sensor for providing an electrical output independent of the differential fluid pressure. A conditioning circuit isprovided for generating a frequency-based signal whose frequency is a function of the electrical output for each fluid pressure sensor. The electrical output of the first and second pressure sensors can be compared to determine whether the pressure transducer needs to be calibrated. In one embodiment, the pressure sensors comprise variable capacitors. The first and second capacitors each have one fixed plate and one movable plate responsive to differential fluid pressure across the movable plate. The reference capacitor has two fixed plates. The first variable, second variable, and reference capacitors are all located in proximity to one another and in communication with the differential fluid pressure. The pressure transducer also includes a switching network connected to the capacitors for selectably connecting at least one of the capacitors to anelectronic circuit.
