Title: Method of tinning metal strip
Inventor: VAN BREDA JACQUES
IPC: C25D21/12
Filed: 1987-02-16
Granted: 1992-10-13
Abstract: A METHOD OF TINNING METAL STRIP               ABSTRACT OF THE DISCLOSURE      Electrolytic tinning is performed in a tinning line having a series of tinning tanks through which metal strip moves while electrolysing current is passed, and having at at least one of the entry side and the exit side at least one buffer apparatus for storing a variable amount of the moving strip.  In order that some speed variation in the tinning tanks can occur, allowing the use of lower capacity buffer apparatuses, the current passing in each tinning tank is adjusted during tinning for portions of the strip.  The current is calculated for a given strip portion by (a)    determination of a value for the thickness of the tin layer on entry to the tinning tank;          (b)    determination of a value for the desired thickness on exit from the tinning tank;          (c)    from the difference of these  values determination of a value g for the desired increase in the tin layer thickness in the tinning tank; and (d)   determination of the instantaneous required value of the current I in the tinning tank in dependence on the value g and the speed v of the strip through the tank.

Granted: 1992-12-22
Abstract: ABSTRACT         A brake for a rotatable shaft is disclosed.  The shaft has an end extending outside of a housing.  The end is adapted to carry a disk generally perpendicular to the shaft.  The housing has a mounting surface facing the disk.          A base is securely affixed to the mounting surface of the housing and two support members are secured to the base and extend from the base past the disk generally parallel to the shaft.  An inner pressure pad is positioned on the support members adjacent to the base interposed in between the base and the disk and generally parallel to the disk.  An outer pressure pad is positioned on the support members with the disk interposed in between the inner pressure pad and the outer pressure pad, and the outer pressure pad is generally parallel to the disk.  Springs are inserted on the support members and interposed in between the inner pressure pad and the outer pressure pad to urge the outer pressure pad away from the disk.  A lever, having a side facing the disk and another side opposite from the disk, is pivotally mounted on the support members at a distance away from the outer pressure pad, and normally extends generally parallel to the outer pressure pad.  Adjusting means are secured to the lever with one end extending to normally contact the outer pressure pad.  A frame member is secured to the support members and to the mounting surface, at a position opposite the support members relative to the shaft, to partially enclose the lever and the disk.  The frame member has a fulcrum formed thereon protruding from the frame member to contact the lever on the side opposite from the disk.  A solenoid is supported by the frame member, and has an armature pivotally attached directly to the lever at a distance Y from the fulcrum.  A second spring is connected to the frame member at one end and at another end to the lever, at a distance Z from the fulcrum which is at least equal to the distance Y.

Abstract: ABSTRACT OF THE DISCLOSURE        A foldable ramp structure is disclosed arranged to be mounted on a pick-up truck and to be used for servicing aircraft or the like purposes wherein the ramp is to provide a stairway to an elevated point.  The invention provides a first stair assembly and an intermediate platform.  Both are fixedly secured to the box of the truck.  A second stair assembly extends forward and horizontally away from the platform, at a level just above the top of the cab of the pick-up truck.  In an extended state, it is only the second stair section which is raised  by pivoting same about a transverse axis located near the rear end of the cab.  m e free end of the second stair assembly is provided with a horizontal, second platform.  Two separate rails are provided, one for the second platform and the other for the second stair assembly itself.  The railing is foldable such that, in a folded state, it clears the intermediate platform and also does not extend beyond the forwardmost end of the second platform.  The device is of a very simple structure and thus inexpensive to produce.  It is especially adapted for convenient securement to an existing  pick-up truck or the like, to avoid the high cost of a specialized vehicle for the purpose.

Title: Augmented air supply for fuel cell power plant during transient load increases
Inventor: BEAL DANIEL W
IPC: H01M8/04
Filed: 1988-05-05
Granted: 1992-06-09
Abstract: Abstract Augmented Air Supply for Fuel Cell Power Plant During Transient Load Increases The performance of fuel cell power plants using air as the oxygen source is reduced during periods of load increase because the response of the fuel cells to the load change is relatively instantaneous.  While cell response is instantaneous, changes in air supply are not.  In order to temporarily increase the air supply to the cells during such a load change, auxiliary solenoid operated valves having high response characteristics are opened to allow greater air flow to the cells.  When the oxygen flow rate is determined to be sufficient for the measured load, the auxiliary valves are closed.
