Abstract: Sodium percarbonate exhibits a tendency to decompose in built compositions a nd particularly detergent compositions built with zeolites. The tendency can be ameliorated by selecting sodium percarbonate which intrinsically has a mean particle size of from 500 to 1000 microns and not more than 20% by weight of below 350 microns and has a moisture pick-up when measured in a test at 80% relative humidity and 32 ~C after 24 hours of not greater than 30g/1000g sample. A suitable sodium percarbonate can be made most conveniently by crystallisation from a bulk saturated solution of sodium percarbonate in a crystalliser/classifier that does not employ a conventional chloride salting - out agent.

Abstract: A ripening room (10) for controlled produce ripening includes side walls (18 and 20). The room (10) receives two rows of boxed produce (26) spaced to define an interstitial volume (50) therebetween. Each row of product (26) is spaced from one of the side walls (18 or 20) to define a side airspace (24) therebetween. The room (10) also includes air control units (32). The side airspaces (24) and the interstitial volume (50) are enclosed to inhibit airflow except through the air control units (32) and through the produce boxes (26). The air control units (32) transfer air from the interstitial volume (50) to the side airspaces (24) during one time period to form a low pressure plenum in the interstitial volume (50) and high pressure plena in the side airspaces (24) to force air to flow from the side airspaces (24) to the interstitial volume (50) through the produce boxes (26). The air control units (32) can reverse airflow direction during another time period to reduce temperature variations in the boxed produce (26).

Filed: 1999-04-06
Granted: 2005-11-22
Abstract: In the circuit arrangement for the high-frequency operation of a low-power low-pressure discharge lamp having a mains rectifier and a half-bridge circuit, a diode is connected in series and in the DC non-conducting direction in the connecting line between the second electrode of the lamp and the positive or negative pole of the rectifier.  Moreover, the tap between the diode and the second electrode is connected to the other pole of the mains rectifier via a capacitor, and a resistor is connected in parallel with the diode. The circuit thus created acts as a passive harmonic filter which fulfills for the circuit arrangement the IEC regulations of class D with reference to line current harmonic content.

Abstract: The mechanical lock of the present invention has an elongated housing (14). A pair of end bushings (40 and 42) mounts in the housing, and a rod (30) translates through the end bushings and at least partially through the housing. A pair of coiled locking springs (60 and 62) within the housing are around the rod and between the end bushings. One end of each locking spring is fixed within the housing, and the other end of each locking spring is free. The normal inside diameter of each locking spring is less than the outside diameter of the rod so that the locking springs secure the rod. A handle (78) can uncoil the free end of each locking spring to increase their inside diameter and release the rod. A wedge bushing (100) mounts in the housing between the locking springs. The face on each end bushing against its respective locking spring is at an angle, and the wedge bushing also has an angled face on the other side of each spring. Therefore, when the rod (30) and housing (14) are loaded with respect to each other, the angled face of one bushing cants one locking spring, and an angled face of the wedge bushing cants the other lacking spring.

Abstract: A modular vibration system which utilizes removable modules to adapt to any of a wide range of applications and performance characteristics. The vibration system comprises a shaker module, a coupling module, and a fixture module. The shaker module includes features for mounting actuators, which provide multiaxial shaking motions, t o the shaker module. The fixture module provides for attaching and holding specimens under test. The coupling module, preferably made of a visco-elastic material, couples the fixture module to the shaker module. The fixture module and the coupling module are easily separab le from the shaker module. This configuration permits tuning the vibration system, over a wide range of multimodal coupling characteristic between the shaker module and the fixture module, for a specific application by interchanging fixture modules and coupling modules. The coupling characteristics can range from very flexible to very stiff and from underdamped to overdamped. The fixture module can ran ge from a honeycomb structure which is lightweight and flexible to a solid structure which is heavy and stiff. The thickness, shape and composition of the coupling module can be selected to adjust the damping and to provide further tuning of the stiffness. The vibration system can be held together by vacuum applied between the shaker module and fixture module or by constant force tension members such as springs. In some cases the specimen itself can function as the fixture module. Particular modes of vibration can be enhanced or subdued by placement of the actuators.

Title: Method and apparatus for non-invasive blood constituent monitoring
Inventor: MILLER DAVID R
IPC: A61B5/145
Filed: 1999-02-05
Granted: 2005-01-18
Abstract: This invention is a system for determining a biologic constituent including hematocrit trans-cutaneously, non-invasive, and continuously.      A finger clip assembly (6) includes at least a pair of emitters, and a photo-diode in appropriate alignment to enable operation in either a transmissive mode or a reflectance mode. At least one predetermined wavelength of light is passed into or through body tissues (7) such as a finger, earlobe, or scalp, etc., and attenuation of light at that wavelength is detected. Likewise, the change in blood flow is determined by various techniques including optical, pressure, piezo and strain gage methods.      Mathematical manipulation of the detected values compensates for the effects of body tissue, fluid, and determines the hematocrit value. If an additional wavelength of light is used which attenuates light substantially differently by oxyhemoglobin, and reduced hemoglobin, then the blood oxygen saturation value, independent of hematocrit may be determined. Further, if an additional wavelength of light is used which greatly attenuates light due to bilirubin (440 nm) or glucose (1060 nm), then the bilirubin or glucose value may also be determined.      Also, determination of the hematocrit with a two step DC analysis technique is disclosed.
