Abstract: A sensor arrangement for producing a signal representative of currents having frequencies and/or characteristics associated with arcing within an alternating current electrical system. The arrangement is coupled to an appropriate arc monitoring circuit which determines if the signal produced by the sensor is the result of arcing within the electrical system.  One embodiment of the sensor arrangement includes an inductor, and a capacitor connected in series with the primary winding of a transformer.   The inductor is typically connected in series with a phase conductor of the electrical system, and the capacitor and the primary winding are connected to the phase conductor in parallel to the inductor. Another embodiment of the sensor arrangement includes a capacitor and the primary winding of a transformer connected in series between the phase conductor of the electrical system and either a ground or neutral conductor of the system. For both embodiments of the sensor arrangement, the secondary windings of the transformers are connected to the arc monitoring circuit.

Abstract: A painting wagon (20) for carrying a plurality of components to be painted through a painting facility is disclosed. The wagon (20) includes a component supporting assembly (50) having a plurality of opposed pairs of component mounting pins (66) fixed thereto. The component supporting assembly (50) is supported by a base structure (22, 26) having wheels (30) which permit the painting wagon (20) to be translated. The component supporting assembly (50) may be selectively adjusted between a contracted configuration in which each of the pairs of opposed mounting pins (66, 66'), and thus the components mounted thereon, are oriented in contracted proximity to one another, so as to minimize the overall size of the wagon (20) with the components mounted thereon to accommodate given dimensional limitations of the painting facility and an expanded configuration in which the pairs of opposed mounting pins (66, 66'), and thus the components mounted thereon, are oriented so as to be expanded apart from one another so that individual components may be mounted and dismounted onto the component mounting pins (66) with reduced danger of bumping an adjacently mounted component and thus damaging the surface finish of the components.

Granted: 2005-06-14
Abstract: An active coloring concentrate can be prepared from the juice of cranberry a nd other fruits or vegetables by treating juice or homogenate with an appropriate binding matrix. Assorted ion exchange resins such as cholestytamine are effective binding matrices, but the currently preferred material is a food grade of cross-linked polyvinylpyrollidone. Whe n appropriate binding matrices are used to concentrate active materials from cranberry, a colored solid is produced. This substance shows significant antibacterial and anti-viral properties. It can be readily consumed as a therapeutic or nutraceutical, used as a coloring agent , or it can be used topically. An additional advantage of the present method is that significant amounts of active concentrate can be produced from cranberrry presscake which is normally a waste material.

Title: Selective acceptance of short message service (sms) messages in a cellular telephone network
Inventor: ALPEROVICH VLADIMIR
IPC: H04W4/14
Filed: 1998-11-19
Granted: 2011-03-15
Abstract: Selective acceptance of short messages enables a cellular subscriber to predetermine which short message will actually be delivered to the subscriber's mobile station. Using an Unstructured Supplementary Service Data (USSD) transmission, the subscriber determines which selection criteria will be used and then builds in the network Home Location Register (HLR) a list of originating entities from which short messages will either be accepted or rejected. A  screening application resident on the HLR then determines the identity of the entity associated with any request for short message routing information and causes the short message to be delivered or deleted according to the input provided by the subscriber. A confirmation message is returned to the originating entity indicating delivery or the reason for failure.

Abstract: The invention relates to a process for the bleaching of chemical pulp and the use of a bleaching solution. According to the invention the pulp is treated in a plurality of different steps by using at least in one step a bleaching solution which contains a peracid, and the essential idea of the invention is that the peracid is used in a post-bleaching which is the last step of the bleaching process, the post bleaching being carried out in the presence of one or more earth-alkali metal compounds. By using a peracid the pulp is brought to its final brightness, and the purpose of the earth-alkali metal added is to combat the lowering of the viscosity of the pulp. According to the invention the post-bleaching can be carried out after the bleach plant steps in a pulp flow pipe, a storage tower or in the paper machine at a paper mill.
