Abstract: Hollow tubing having a generally rectangular cross-section has a longitudinal ridge along a top and a corresponding longitudinal channel along a base. Pieces of tubing can be stacked on top of one another with the ridge of one piece of tubing engaged in the channel of another piece of tubing.  The truck or trailer has a peripheral frame and a first piece of tubing is welded to an edge of that frame with the ridge extending upward.  Caulking is then placed along the ridge and a second piece of tubing is placed on the first piece so that the ridge of the first piece is located within a channel of the second piece.  This method is repeated until a wall of desired size is constructed.  Pieces of tubing subsequent to the first piece, are not welded to one another.  When the wall is completed, U-shaped brackets are welded to each end.  No pre-existing supports, whether vertical or horizontal are required.  The tubing is extruded aluminum and presents smooth outer and inner surfaces upon completion.  Presently, aluminum boxes are constructed for trucks and trailers using aluminum flats or strapping that are welded or riveted to pre-existing vertical and/or horizontal supports.

Title: Electronic module of extra-thin construction
Inventor: NICKLAUS KARL
IPC: H01L21/56
Filed: 1993-11-23
Granted: 1998-01-06
Abstract: In the electronic module (M) of extra-thin construction disclosed, it is the principal object to substantially reduce the tendency to fracture of the module's semiconductor chip (1) embedded in the plastic casing (10) of the module (M), notwith-standing the extremely small thickness of the casing. The chip is fitted on the chip pad (22) of a system support (20) formed by a thin metal strip, commonly known as a lead frame. The chip (1) may partly overlap the external contacts (21) of the module that lie on one of the flat sides of the module's plastic casing (10). Slits (23) in the system support, which form the boundaries of the chip pad (22) and are inevitable lines of weakness in the thin metal strip, are situated at an oblique angle relative to the edges of the square or rectangular chip (1), preferably at about 45°; hence the slits extend also at an oblique angle to possible fracture lines within the monocrystalline structure of the material used in chip manufacture, because said fracture lines are parallel to the chip's edges. Other slits (24) in the metal strip, which extend from said boundary slits (23), should preferably also be at an angle relative to the edges of the chip. Further characteristics disclosed relate to the  mechanical bond between parts of the system support (20) and the module casing (10), and the bonding of the entire module (M) to the surrounding plastic material when it is moulded into a supporting body or medium, for example in the manufacture of chip cards.
Patent CA-2116055-C (CA)
Inventor: ANGRAVE JANICE E
IPC: G12B9/02
Filed: 1994-02-21
Granted: 1998-04-07
Abstract: An encased electronic instrument of the type having a front panel bearing controls and visual displays that is clamped to the forward periphery of a box-like case,  is provided with a resiliently deformable  and  elastically  stretchable  identifying  shield surrounding and overlying the front panel, and extending a given distance rearwardly generally parallel to the outer surface of the instrument case.  The shield is preformed, with an outer peripheral band defining an open center having a shape slightly smaller than, but generally conforming to the outer shape of the front panel and the rearwardly extending outer surfaces immediately adjacent to the front panel. A first inwardly extending flange projects from the forward edges of the peripheral band in overlying relationship with the outer edges of the front panel of the instrument, and a second inwardly extending flange projects from the rearward edges of the peripheral band to enhance frictional engagement between the band and the underlying outer surfaces of the instrument.  The second inwardly extending flange may also serve to retain the shield on the front panel and to provide sealing between the panel and the case, by being clamped between the rear surface of the front panel and the forward edges of the side surface portions of the case, replacing the sealing gasket previously described as being used in the prior art.  The material from which the shield is formed is resiliently deformable and elastically stretchable, so that it can be  stretch-fitted  over the  front panel  of an  instrument  in peripheral elastically gripping relationship; the thickness of the body of the shield is selected so that the force of unintended impacts with the outer surface of the shield will be absorbed in part in the shield and will be transmitted in part to the abutting surface of a panel in which the instrument is mounted, and will also be transmitted, with reduced intensity, to the outer surface of the instrument. The shield also serves to provide convenient and ready  visual  differentiation  among  a  plurality  of  clustered instruments, as in a control board, through the use of distinctive colors which may be applied to the surface of the shield or which may be made an inherent part of the shield material.   Visual identification is further enhanced by molding distinctive words or symbols into a visible surface of the shield.

Abstract: A veneer lathe apparatus and method are described in which the height of the nose bar roller relative to the knife is automatically adjusted during peeling by a computer control system. In addition, the two veneer exit gaps between the nose bar and the knife and between the nose bar and the knife backing member are automatically maintained substantially the same as or slightly greater than the veneer path width which is equal to the thickness of the veneer plus a clearance space of a predetermined amount. As a result the automatic control positions the nose bar as close as possible to the knife during peeling thereby greatly improving the quality of the veneer. The height of the nose bar is adjusted by moving a moveable wedge along a fixed wedge with a control cylinder in response to a computer generated control signal. A resilient hold-down device is employed for mounting the nose bar carriage to enable its horizontal movement and vertical movement with respect to the main carriages during peeling due to height adjustment and horizontal gap adjustment of the nose bar relative to the knife.

Abstract: A motor control system includes a single, multicompartment enclosure mounted on a skid.  The enclosure contains a transformer circuit and a motor controller circuit interconnected so that only external connections to a power source and a load are needed.   When the circuits are energized, access to high voltage motor control components and to field replaceable fuses and output selection switches is prevented by a double interlocking mechanism which operates in conjunction with energizing and de-energizing the transformer. The transformer of the transformer circuit includes a tertiary winding disposed radially between a primary winding and a secondary winding.  The winding filters electrostatically coupled  transients.    A  conventional  electrostatic shield  is  also  used  so  that  the  transformer  is  doubly shielded to electrostatic transients.  The tertiary winding is connected to one or more capacitors to filter magnetically coupled transients.   A current limiting fuse, a load sensing fuse and a primary make/break switch are connected in electrical series to the primary winding.  Methods for energizing or operating a motor utilizing the primary switch and the load sensing fuse are also disclosed.

Abstract: Power consumption in an electrical system, particularly a battery powered computer system, may be reduced by a method in which the performance of the system's power consuming assets (e.g., 1/0 devices, memory, processors, etc.) is monitored during the operation of application programs. The performance metrics (e.g., time on, processing assets, instruction density, etc.) for each of the application programs is stored in a look-up table below the application program software level that is accessible to the basic input/output system and/or disk operating system. The look-up table may be dynamically updated each time an application program is run. The data in the look-up table are used to remove all or part of the power from those assets that require no or less power during operation of a particular application program. The method is transparent to the application programs and may use a terminate and stay resident programs.
