Title: Price updating apparatus
Inventor: POLAND TERRELL
IPC: G06Q20/20
Filed: 1992-08-24
Granted: 1998-04-21
Abstract: An improved price updating apparatus for use in retail store pricing systems has an input for receiving update data indicative of a product for which a price change is desired and the changed price.  The apparatus looks up records in a database relating to store locations, for locations where the product may be found.  Where the location has an electronic price display device, preferably connected with the apparatus by a serial data link, the changed price is transmitted to the display device by the serial data link.  Where the location has a printed price, the apparatus stores a print job record containing information about the price and the shape and size of the printed price.  A user is later able to select, one by one, the various shapes and sizes of printed prices, and to print all the records intended for printing at the selected shape and size.

Abstract: A method of brewing a malt beverage having a low alcohol content is disclosed. A malt and cereal infusion having an extract content below about 14% is prepared, and boiled to obtain a wort. A predetermined quantity of hops are then added to said wort, which is then aerated to an oxygen content of 15 - 35 .mu.g per litre. The wort is pitched with a yeast slurry to provide a cell count of about 80 to about 180 million yeast cells per ml and fermented at a temperature of about 3.degree.C to about 10.degree.C for 1 to 40 hours. The yeast is then removed from the fermented wort, and the resulting brew is filtered, and electrolyzed with a copper electrode to remove H2S. The alcohol concentration of the brew is then adjusted with carbonated water to a preselected level, and then the resultant brew is aged for at least 24 hours.

The high cam portions and the low cam portions are spaced-apart from the rotor and the high cam portions are closer to the rotor than the low cam portions. The vanes extend further from the rotor in the low cam portions compared to the high cam portions so the fluid receiving spaces are compressed when adjacent the high cam portions compared to positions adjacent the low cam portions. There is an air intake means for intaking air into the spaces. A fuel intake means for intaking fuel into the spaces. There is a spark plug for igniting an air/fuel mixture in the spaces and an exhaust for exhausting exhaust gases from the spaces.

IPC: H01M50/497
Filed: 1994-10-07
Granted: 2006-09-19
Abstract: This invention relates to an organic electrolyte lithium secondary battery wherein lithium works as an active material, and comprises a negative electrode made of metallic lithium or lithium alloy, and relates more particular to a separator of the same battery. A conventional battery uses a separator made of polyethylene and/or poly propylene, however, this invention uses microporous polyolefin membrane as a separator matrix whose pores are filled and closed with ionic conductive gel electrolyte. The separator uses a sheet whose at least one face contacting the negative electrode has a gel electrolyte layer on it.   The gel electrolyte is formed by irradiating ultraviolet ray to a mixed solution wherein a mixture of which major components are oligomer and monomer polymerized by ultra violet ray is added to organic electrolyte.        By using the separator according to this invention in an organic electrolyte lithium secondary battery, internal short circuits due to dendrited lithium growing on a negative electrode during a charge can be prevented, and a longer cycle life is expected. Further, burning accidents can be reduced. A highly reliable lithium secondary battery can be thus achieved.      Note: The expression "dendrited lithium" means that metal lithium deposited on a negative electrode grows in a form of (or in a shape of) dendrite.
