Abstract:
Methods and apparatus for fabricating a semiconductor sheet are provided. In one aspect, a method for fabricating a semiconductor wafer includes applying a layer of semiconductor material across a portion of a setter material, introducing the setter material and the semiconductor material to a predetermined thermal gradient to form a melt, wherein the thermal gradient includes a predetermined nucleation and growth region, and forming at least one local cold spot in the nucleation and growth region to facilitate inducing crystal nucleation at the at least one desired location.
Abstract:
The present invention provides stable aqueous thermosetting binder compositions having a total solids content of 15 wt. % or higher, preferably, 20 wt. % or higher, and having extended shelf life comprising one or more reducing sugar, one or more primary amine compound, and one or more stabilizer acid or salt having a pKa of 8.5 or less. The total amount of stabilizer used may range from 5 to 200 mole %, based on the total moles of primary amine present in the binder. The stabilizer may be an organic stabilizer chosen from a monocarboxylic acid, a dicarboxylic acid, a fatty acid, an acid functional fatty acid ester, an acid functional fatty acid ether, or an inorganic stabilizer chosen from a mineral acid, a mineral acid amine or ammonia salt, and a Lewis acid, and mixtures thereof. The compositions can be used to provide binders for substrate materials including, for example, glass fiber.
Abstract:
A lead-acid battery comprising: at least one lead-based negative electrode; at least one lead dioxide-based positive electrode; at least one capacitor electrode; and electrolyte in contact with the electrodes; wherein a battery part is formed by the lead based negative electrode and the lead dioxide-based positive electrode; and an asymmetric capacitor part is formed by the capacitor electrode and one electrode selected from the lead based negative electrode and the lead-dioxide based positive electrode; and wherein all negative electrodes are connected to a negative busbar, and all positive electrodes are connected to a positive busbar. The capacitor electrode may be a capacitor negative electrode comprising carbon and an additive mixture selected from oxides, hydroxides or sulfates of lead, zinc, cadmium, silver and bismuth, or a capacitor negative electrode comprising carbon, red lead, antimony in oxide, hydroxide or sulfate form, and optionally other additives. The capacitor electrode may be used in asymmetric capacitors and batteries of other types.

Abstract:
This invention has to do with exercise weight equipment and is concerned with exercise weight equipment that may be fastened to a person's body during physical exercises. The exercise equipment comprises a preferably U-shaped bracket having opposing sides and a crossbar or rod that extends between and engages the opposing sides of the U-shaped bracket. The crossbar is spaced away from the U-shaped portion of the bracket so that the instep of a person's foot may be engaged between the bar and the opposing U-Shaped portion of the bracket. Strap means connect from one or both of the opposing sides of the U-shaped bracket and extend so as to be able to go around the ankle of a person using the equipment. Means for fastening the strap mean extensions are provided and may take the form of a buckle and belt means. The outer ends of the crossbar or rod have means thereon for engaging and holding captive weights that may be interchanged at will by the person exercising. Various methods of exercise using the above equipment are also disclosed.
Abstract:
A cabinet liner for a vanity or kitchen cabinet or any other similar cabinetry located in these areas. The cabinet liner comprises of a tapered wall around its entire perimeter and a lip with grooves that can be trimmed or flexed along the sides and back. The cabinet liner consists' of a liquid impervious, flexible and shape retaining, rubberized plastic. The cabinet liner is molded of a simple one piece design that can be contorted to fit through a door of any existing bathroom and kitchen base or wall cabinets. The cabinet liner can be manipulated into place an covers the entire inside floor of said cabinets forming a tray for receiving goods and protecting cabinet from small plumbing leaks and spills from goods stored thereon until realized.

Abstract:
An excess inventory system monitors excess material. In the system, requirements are determined for each component part over a predetermined period (e.g., 6 months) from material requirements planning (MRP) data. When forecasting for the component part is to be determined using an MRP planning method, the MRP data is used to determine a number of excess component parts. The number of excess components is then recorded in a record for the component part within an excess inventory table. When forecasting for the component part is to be determined using an alternate planning method which is alternate to MRP, the alternate planning method is used to determine a number of excess component parts. The number of excess components and a notation indicating the alternate planning method used are then recorded in the record for the component part within the excess inventory table.
