Title: Projection type image display apparatus with circuit for correcting luminance nonuniformity
Inventor: SHIOTA TETSURO
IPC: H04N9/31
Filed: 1995-12-13
Abstract: In a projection type image display apparatus, the screen is divided and a memory to record luminance correction data corresponding to the divided regions is provided, and addresses of the divided regions of the screen are set by an address counter, synchronized with the input video signal. The luminance correction data are read successively by inputting the addresses to the memory, and luminance nonuniformity on the screen is corrected through operational processing of the correction value converted in an analog value by a D/A converter and the input video signal. The luminance correction data is obtained by computing measurement results of respective luminance characteristics of red, green, and blue colors on the screen and separately recorded as an amplitude correction component and a DC level correction component. By multiplying and adding the correction data to the input video signal respectively, nonuniformities in luminance and color from low luminance level to high luminance level can be precisely corrected. Also, as the read start position and read direction of the memory can be set corresponding to sweep direction of a projection type image display apparatus, the projection direction to the screen in a projection type image display apparatus can be easily changed without affecting the operation of luminance correction.
Patent CA-2165171-A1 (CA)
Title: Oven module with intermediate expansion joints
Inventor: JOSEFSSON LEIF E
IPC: F23M5/00
Filed: 1994-06-13
Abstract: An oven module (10) for use in industrial baking applications is disclosed having apparatus for accommodating the longitudinal thermal expansion in the interior walls (12, 14, 16) of the oven module located intermediate the ends of the module. The oven module is easily assembled into an oven baking line because its ends are fixed and do not vary due to thermal expansion. Therefore, the present oven module alleviates numerous disadvantages in the shipping and assembly of an oven baking line which has been experienced with prior known oven modules. The floor, walls and roof of the oven module have both an interior (30, 52, 82) and an exterior (18, 68, 74) structure so that the interior surfaces (38, 54, 84) of the oven module can be independently and rigidly supported. At opposite ends of the module, the interior and exterior structures for the floor, walls and roof are fixed to a common support member (20, 36, 58, 60, 80). Because the interior surfaces are fixed at opposite ends of the oven module, longitudinal thermal expansion therein is directed inward, toward thermal expansion joints (42) which are located intermediate opposite ends of the module. Also included in the present invention is an improved explosion relief arrangement (102, 104) which contributes to the overall rigidity of the oven module while still meeting the requirements for explosion relief of the oven module.

Title: Adjustable elastomer bias device using bendable resilient rods
Inventor: GORDON JAMES R
IPC: F16F1/36
Filed: 1996-03-18
Abstract: An adjustable elastomer bias device includes a base member (metal or rigid plastic) having  plural receptacles for receiving one end of each of a like plurality of bendable, resilient, elastomer rods.  An index member is included in the device; the index member has plural rod guide passages and each elastomer rod passes through one guide passage so that the index member can slide longitudinally along the rods, toward and away from the base member.  The index member is anchored at one of several displacement distances from the base member to change the effective stiffness (bias) of the rods.  The index member may be rotated for torsional bias or moved laterally for linear bias to effect a further bias adjustment; a retainer holds the additional bias adjustment.  The bias force of the device results from bending of the elastomer rods.

Title: Halogen incandescent lamp with filament positioning arrangement
Inventor: STREPPEL HANS-JUERGEN
IPC: H01K1/18
Filed: 1996-06-05
Abstract: To positively locate a filament (5, 22) in position within a bulb (2) of a halogen incandescent lamp, the walls of the bulb are deformed at selected points along the length of the filament within the bulb to define at least three inwardly projecting dimples which just barely engage, or engage, the filament. Preferably, the filament is formed with a connecting portion (7) in the region of engagement, which connecting portion is either straight, coiled with a very steep pitch, or, if the filament is double-coiled, only single-coiled.  The connecting portion (7) may be electrically short-circuited by a core pin (39).  If the bulb is single-ended (Fig. 3), a return lead (29) along the wall of the bulb, can be pinched between adjacent walls (45) of adjacent dimples.  The dimples, looked at from the outside of the lamp, are essentially funnel-shaped and, in cross section, may be circular, or if space between adjacent dimples is insufficient, may be elliptical.

IPC: F24H9/20
Filed: 1994-12-27
Abstract: An engine-independent vehicle heating appliance has a combustion air fan, a fuel dosing pump and a heat exchanger that surrounds the combustion chamber, as well as a controller that controls the operation of the vehicle heating appliance.          In compact designs, special measures are required to protect the electronic components of the controller from overheating.          In order to carry off heat  in an effective manner,  the controller  has  a  heat  conducting  plate  upon  which  the electronic power components (18) are mounted, their connections being electrically connected to the wiring on the board (16).        Loss heat that results from the operation of the components (18) is carried away by the material of the heat conducting plate (8a, 8b) to the fan housing (6).  Since the latter is always cool, a sufficient cooling of the components (18) is ensured.
