Title: Video signal gradation corrector
Inventor: TSUJI TOSHIAKI
IPC: H04N5/20
Filed: 1992-05-25
Granted: 1999-08-31
Abstract: A video signal gradation corrector used in a television receiver or the like for preventing the destruction of the gradation of the black side and the floating of the luminance level of the black side and/or an excessive increase of the luminance level of the white side. The corrector can be realized with a small circuit scale. A histogram operating circuit includes an average luminance level detecting circuit. A constant is subtracted from an output signal of the average luminance level detecting circuit by a subtractor. The result of subtraction is multiplied by a constant by a constant-multiplication circuit. A lower-limit limiter circuit limits an output signal of the constant-multiplication circuit to a signal having a value not smaller than 0. An output signal of the lower-limit limiter circuit is provided as an accumulation start luminance level, thereby enabling a gradation correction in which the floating of the luminance level of the black side and the destruction of the gradation of the black side are prevented. Also, the average luminance level and a constant may be added by an adder. The result of addition is multiplied by a constant by a second constant-multiplication circuit, and is limited to a certain value by an upper-limit limiter circuit. An output signal of the upper-limit limiter circuit is provided as an accumulation stop luminance level, thereby enabling a gradation correction in which an excessive increase of the luminance level of the white side is prevented to suppress the blooming of a CRT.

Title: Miniature fiberoptic bend device and method
Inventor: STOWE DAVID W
IPC: G02B6/38
Filed: 1991-06-17
Granted: 2002-11-26
Abstract: Bends in optical fibers (14) can be miniaturized by reducing the diameter of a section (18) of the fiber in the region where bending (20) is desired. In one aspect of the invention radii of curvature less than 100 microns and very low optical power loss are achieved. A fiber with greatly reduced diameter (Fig. 1d, Section-b-b) may also be twisted about its longi-tudinal axis to a greater degree than a comparable length of larger diameter fiber. In another aspect of the invention, reduc-ing the cross-sectional area of fiber is not required. Bent sections of the fiber are thermally annealed forming stress free bends of minimum bend radius for long term applications. Any optical fiber can be processed by redrawing and/or chemical means to allow such bending or twisting. Bend or twist tolerant regions and annealed bends may be packaged separately or built integrally into a wide range of fiber optic components; sensors; networks, or systems with significant space savings, added performance features and mechanical flexibility.

Title: Mass spectrometry method using supplemental ac voltage signals
Inventor: KELLEY PAUL E
IPC: G01N27/62
Filed: 1992-08-28
Granted: 2002-07-02
Abstract: A mass spectrometry method in which a supplemental AC voltage signal having at least one high power frequency compo-nent, and at least one low power frequency component, is applied to an ion trap. Each high power component has an amplitude sufficiently large to eject one or more selected ions from the trap, by resonantly exciting the ions. Each low power component has an amplitude sufficient to induce dissociation (or reaction) of one or more selected ions, but insufficient to resonate the ions for detection. The frequency (or band of frequencies) of each high and low power frequency component is selected to match a reson-ance frequency of ions having a desired mass-to-charge ratio. Each low power component is applied for the purpose of inducing dissociation or reaction of specific trapped ions, which may be parent, daughter, reagent, or product ions, and each high power component is applied to eject undesired products of each such dissociation or reaction process from the trap. In accordance with the invention, a supplemental voltage signal having appropriately selected high and low power frequency components is applied to a trap during an (MS)n or Cl, or combined Cl/(MS)n, mass spectrometry operation.

Title: Chocolate conching
Inventor: CAPODIECI ROBERTO A
IPC: A23G1/14
Filed: 1993-04-02
Granted: 1996-12-17
Abstract: A process and a system for combining and physically working chocolate-making ingredients are provided. A variable fre-quency drive (35) controls the motor (34) of a conching device (29) to increase the efficiency by which energy is imparted to choc-olate ingredients during conching. This automatic variable speed approach permits the power to be maintained at a relatively con-stant and maximum rate, with the speed being determined by the consistency of the ingredients themselves. Feedback associated with the automatic speed variation can be used in order to reduce conching times and vary the quantity of certain ingredients and the timing of and location of their introduction. By the invention, it is possible to standardize the chocolate product during the conching operation and thereby avoid a post-conching standardization procedure with respect to characteristics such as viscosity and fat content.

Title: Campfire reflective sheet
Inventor: KELLY MICHAEL
IPC: A47C7/74
Filed: 1995-02-24
Granted: 1997-06-03
Abstract: When a person is sitting in a chair facing an outdoor campfire, the radiant heat created from the fire can only be felt on parts of a person's body directly exposed to the fire. Other parts of the body not directly exposed to the radiant heat, such as a person's rear thighs and back, will often feel cold in cool environmental conditions. Using the radiant heat generated from a campfire, a flexible sheet with a textured reflective surface, attached to the top rail backrest of a chair and to the bottom rail between the two front legs of a chair forming a curve or an arc under the chair, will reflect the radiant heat in an upward direction warming those parts of a person's body not normally receiving heat. The sheet is shaped to fit between the rear legs of generally any typical outdoor folding chair.

Title: Nondigestible fat compositions containing diversely esterified polyol polyesters for passive oil loss control
Inventor: CORRIGAN PATRICK JOSEPH
IPC: A23L19/18
Filed: 1993-10-21
Granted: 1999-02-23
Abstract: Nondigestible fat compositions useful as a replacement for triglyceride fats or oils in foods are disclosed. These compositions have relatively flat Solid Fat Content (SFC) profile slopes between typical room and body temperatures. The nondigestible fat compositions comprise a liquid nondigestible oil and nondigestible particles of solid polyol polyester material dispersed in the oil in an amount sufficient to control passive oil loss. The ester groups of the solid polyol polyester material comprise: (i) at least about 15 % ester groups formed from C20-C26 long chain saturated fatty acid radi cals, and (ii) ester groups formed from fatty or other organic acid radicals which are dissimilar said long chain saturated fa tty acid radicals. The molar ratio of said dissimilar acid radicals to said long chain saturated fatty acid radicals ranges from about 0.1:7.9 to about 3:5. Moreover, the dissimilar acid radicals cannot consist solely of C2-C12 short chain saturated f atty acid radicals, C20 or higher long chain unsaturated fatty acid radicals, or a combination of said short chain saturated and said long chain unsaturated fatty acid radicals. Edible fat-containing products containing these nondigestible fat comp ositions can be less waxy tasting due to the lower level of solids required for passive oil loss control.
