Title: Elimination of film defects due to hydrogen evolution during cathodic electrodeposition
Inventor: WINKLE MARK R
IPC: C25D13/06
Filed: 1991-07-22
Abstract: Abstract of the Disclosure This invention is directed to a method for eliminating or reducing pinhole defects in cataphoretically deposited films without interfering with the electrolysis of water needed for electrodeposition. This method comprises decreasing the evolution of hydrogen gas at the cathode by adding a compound to the emulsion. This compound is reduced by the hydrogen produced at the cathode during the electrodeposition. The hydrogen reacts with the this non-gaseous compound rather than becoming hydrogen gas and forming bubbles which lead to pinhole defects.

Inventor: TUCKER DANIEL G
IPC: E05C9/02
Filed: 1991-08-27
Abstract: A universal lock for securing any of a variety of different design window sashes closed against any of a variety of different design window frames.  The lock in-cludes a pair of spaced keepers on the window sash, and a tie bar mounted to the window frame and having a pair of rollers thereon.   The tie bar is reciprocable along its axis to selectively move the rollers into or out of engage-ment with the keepers of the closed window sash to selec-tively lock or release the sash from the frame.   A base pivotally mounts a handle member to the window frame.  A coupler link is pivotally secured at one end to the handle member and has a flange at the other end pivotally secured to the tie bar.  The flange has a narrow portion with a first width adjacent the coupler link and a wide portion with a second width spaced from the coupler link.  The tie bar includes an opening with a substantially circular por-tion having a diameter greater than the first width and less than the second width, and a slot portion wider than the second width.  The coupler link is positioned at a non-operational angle relative to the tie bar during assembly to allow passage of the flange wide portion through the tie bar opening slot portion.  The flange wide portion thereaf-ter holds the coupler link to the tie bar with the flange narrow portion pivotable within the tie bar opening circu-lar portion during operational (i.e., locking and releas-ing) pivoting.

Title: Fluid transport apparatus with water hammer eliminator system
Inventor: ZINK DONALD G
IPC: B61D5/00
Filed: 1991-10-09
Abstract: A fluid transport apparatus including an elongated fluid vessel for transporting fluid, such as LPG. One or more breakable containers of compressible fluid are positioned within the fluid vessel. The con-tainers are adapted to break by the force of the vessel fluid surging against them when the fluid vessel is impacted. The compressible fluid within the containers dissipates or eliminates the water hammer pressure resulting from the impact and thereby prevents the walls of the fluid vessel from failing. The breakable containers can be end partitions with one or more rupture discs thereon or collapsible pres-surized containers, such as ordinary tennis balls, held at one or both vessel ends by internal breakaway partition walls.

Patent CA-2057458-A1 (CA)
Title: Magnet system
Inventor: UNKELBACH KARL-HEINZ
IPC: B03C1/02
Filed: 1991-12-10
Abstract: Abstract Magnet System In a known magnet system, specifically for magnetic separators, having homogeneously magnetized magnet blocks arranged in circular ring shape, the magnet blocks have their magnetization directions aligned differently from one to another and established in accordance with a predetermined mathematical formula.          While a magnetic field running almost uniformly over the whole region of the magnet system is thus produced, the magnet blocks are made trapezoidal in cross section and, because of the many distinct magnetization directions, require separate fabrication.  Both the fabrication and the assembly of these magnet blocks are therefore relatively complicated and time-consuming.          In accordance with the invention, however, the fabrication and the assembly of the magnet blocks into a magnet system are quite substantially simplified and improved by virtue of the fact that the magnet blocks (1) are made square in cross section.

Title: Multichannel device for measurement of weak spatially and temporally varying magnetic fields
Inventor: AHONEN ANTTI I
IPC: G01R33/035
Filed: 1991-12-10
Abstract: The invention concerns a superconducting device used to measure temporally and spatially varying magnetic fields generated by sources inside the object to be investigated. The invention consists of a body divided into separate and easily interchangeable self-supporting modules, interconnected by connectors. The superconducting magnetometer or gradiometer elements (12) have been attached by means of connectors (11) to the cross-connection/support element (6); this element (6) is attached to a connecting element (4) by means of connectors as well. The connecting element (4) contains also the electric components (5) necessary for connecting the SQUIDs to the room temperature electronics (14).  The connecting element (4) is attached to the neck plug (3), comprising a stiff thermal isolation preventing convection and a ribbon cable made of parallel twisted pairs.      The element (3) is self-supporting and it farms an integral part of the magnetometer support structure. The cables in the neck plug have been made out of wires having a relatively high resistance in order to minimize the heat leak between the room temperature and the cryogenic environment of the magnetometers; the excess noise caused by the resistive leads has been compensated, for example by increasing the SQUID gain using positive feedback.

Abstract: CANADA                  CONSTANT FORCE GAS SPRING      JAMES KLASSEN                 ABSTRACT OF THE DISCLOSURE         A constant force gas  spring has a primary cylinder, a secondary cylinder or piston movable within the primary cylinder, and a rod fixed to the primary cylinder and extending into the secondary cylinder. A diaphragm connects between the primary and secondary cylinders, and the primary cylinder is dimensioned to allow the diaphragm to expand as the secondary cylinder moves away from full compression, with the result that the gas spring gives a constant force along the line of travel of the secondary cylinder. The cross-sectional area of the secondary cylinder is kept to a minimum, which extends the range of the constant force for a given volume and allows the gas spring to be made with reduced volume for a given range. The effective cross-sectional area of the secondary cylinder is kept to a minimum even when its circumference is increased by enlarging the rod, and by making the  secondary  cylinder  elliptical.  A compound flare section for the primary cylinder is also described.
