Abstract: A medical waste disposal device having a blade that rotates and chops medical waste into chips and other small particles. The blade includes at least one opening with at least one sharpened edge. The blade also has at least one raised portion adjacent to the sharpened edges. The blade cooperates with a cutting plate to chop or scissor the medical waste. The raised portion pushes chopped medical waste away from the blade and the cutting plate.

Abstract: Cosmetic particle compositions are provided which are adapted to form hard cosmetic particles that transform to soft cosmetic particles after their incorporation into topical formulations, particularly surfactant-based topical formulations. The composition includes one or more partially or fully hydrogenated triglyceride oils, at least 50% of which have at least 15% by weight fatty acid moieties with carbon chain lengths of C18 or higher. Additives may be disposed in or on the hard cosmetic particles and delivered when the cosmetic particles are broken proximate a target such as the skin, hair or nails of a mammalian subject or another target. The transformable hard cosmetic particles permit the storage and shipment of intact cosmetic particles yet transform in situ to achieve the benefits of soft cosmetic particles.

Abstract: Botanically-sourced and botanically-derived emollient sanitation compositions for topical use are disclosed. Representative compositions generally aid reconstitution of the lipid profile of the stratum corneum by providing botanical lipids and/or lipid-derivatives that resemble human sebum—these components being ordinarily diminished with the use of conventional hand sanitizer products. Disclosed features and specifications may be variously controlled, adapted or optionally modified to realize, for example, improved hand sanitizer formulations. Representative embodiments of the present invention generally provide anti-microbial compositions blended with botanically sourced lipids and/or lipid-derivatives to control or otherwise improve dermatitic symptoms associated with frequent use of conventional hand sanitizer products.

Abstract: Apparatus for minimizing power losses associated with dead time between ON times of two series connected switches of a power converter connected across a supply potential, the apparatus comprising a control arrangement for monitoring a selected parameter associated with power loss during the dead time of the converter; the control arrangement changing the dead time from a first dead time to a second dead time and comparing power loss associated with the selected parameter for the first and second dead times and determining which of the power losses associated with the two dead times is smaller; a dead time implementing stage for implementing the two dead times; and the control arrangement selecting the dead time associated with the smaller power loss and providing a signal to the dead time implementing stage to set the selected dead time.

Abstract: The present application relates to a chemiluminescent saliva ejector. The chemiluminescent saliva ejector includes a first tube and a second tube positioned concentrically within the first tube: leaving a space between the first and second tube. The chemiluminescent saliva ejector also includes a deformable partition separating the space into a first chamber and second chamber, where chemiluminescent components are contained. Upon deformation of the deformable partition, the chemiluminescent components mix to produce luminescence.

Abstract: A frequency modulation controller for use in controlling a switched mode power supply including an input terminal for receiving an input voltage and at least one switch selectively turned on and off to control the output voltage of the power supply in accordance with an embodiment of the present invention includes an analog to digital converter operable to convert a feedback signal indicative of the present output voltage into digital data, a digital conditioning unit operable to provide an error signal based on the digital data from the digital to analog converter for use in generating the frequency modulation signal and a digital to analog converter operable to provide the frequency modulation signal based on the error signal, wherein the frequency modulation signal indicates a desired duty cycle of the at least one switch to maintain a desired output voltage such that the at least one switch of the switched mode power supply is turned on and off in accordance with the desired duty cycle.

Abstract: A switch mode power supply in which a control loop responsive to an input signal representative of the power supply output to provide a compensated error signal; and a PWM signal generator responsive to the compensated error signal to generate a variable duty cycle drive signal for the drive circuit having a selectable repetition rate. The control loop is implemented by digital circuitry, and the PWM signal generator is implemented by analog circuitry.

Abstract: Apparatus for setting dead time between ON times of two series connected switches of a power converter circuit connected across a supply potential, the apparatus comprising a circuit for monitoring a power converter circuit parameter and providing an output corresponding to the circuit parameter; a memory addressed by a signal related to the output of the monitoring circuit, the memory having values stored therein related to the dead times and associated with values of the circuit parameter; a processor providing an output of the memory associated with the value of the circuit parameter to set the dead time corresponding to the stored value in the memory, and a dead time implementing stage for implementing the dead time in accordance with the output of the memory.

Abstract: A tool for dislodging lubrication-blocking debris from machinery elements. A housing includes a forward internal chamber. An adapter receives an explosive charge element and completes the chamber. The adapter includes an exteriorly-threaded portion for affixation of the tool to a lubrication access hole. A firing mechanism is positioned and spring loaded at a rear chamber of the housing. In use, the tool is inserted in place of a grease nipple and the explosive charge element detonated, for example, by striking the exposed end of the firing mechanism with as a hammer. A pulse of pressurized gases is thereby generated to clear the blocked lubrication passage.

Abstract: An emollient composition comprising at least 5-30% by weight polyethylene, 0-60% by weight petrolatum, and 0-50% octyl palmitate. These emollient compositions may be used as emollient carriers for various materials, such as fragrances and pigments or dyes, to be externally applied to the skin. These emollient compositions may be formed into particulate shapes, such as spheres, for subsequent use in cosmetic products.

Abstract: A process for the production of an epoxide and/or its corresponding vicinal diol by a reaction of an olefinic compound with hydrogen peroxide, wherein the reaction is performed in the presence of a carbon dioxide phase at a temperature and a pressure above the critical point of carbon dioxide.

Abstract: A feeding tray construction and method that prevents the escape of strong beaked birds during feeding comprises (i) a central stationary box closed along side and back panels, partially open at a top panel but fully open along its front entrance, (ii) an inverted drawer slidable within the central box, partially open or fully open along its top and bottom and closed along front, sides and back panels, and (iii) removable dishes or dish residing within the drawer.

Abstract: The invention contemplates improvement and economy in demineralization of the total flow of recirculating water in a steam-generating system which includes a condenser for recovery and recirculation of feed water. This filter demineralizer operates on a relatively small fraction of the total flow, being available as a relatively small flow of high-temperature water collected from steam-generator blow-down, from steam-separator drainage, or from other high-temperature drainage from a steam-utilization device. The purified effluent from the filter demineralizer is returned to the circulatory system for supply as pumped feed water along with other feed water pumped from condensate accumulation.

Abstract: A stud cleaning machine whereby the threaded portion of very large studs can be cleaned to a semi-bright finish. The cleaning machine is designed to completely enclose the studs during the cleaning operation, so that none of the loosened oxides, residues, and caked lubricants are discharged into the surrounding atmosphere. The contaminated particles are retained in the cleaning machine and removed through an attached vacuum cleaner.
