Patent number: RE30537Abstract: A low wash and rinse temperature (120.degree.-140.degree. F.) warewasher accomplishes the same general washing and rinsing effectiveness as a conventional high temperature (150.degree. F. minimum wash, 180.degree. F. minimum rinse) warewasher without loss of productivity resulting from time lost between completion of washing and commencement of rinsing a given load of ware, through use of independent, dedicated wash and rinse systems, the latter of which includes a holding tank which enables independent batching of a predetermined volume of rinse solution from properly-proportioned fresh water and sanitizing agent while washing a given load of ware. The sanitizing agent is introduced independently into the holding tank and independently of the fresh water line, and is therefore unaffected by a great range of water line pressures and the mineral conditions of the water.Type: GrantFiled: August 20, 1979Date of Patent: March 3, 1981Assignee: Hobart CorporationInventors: Louis F.

Patent number: T100402Abstract: A method and means for modifying up to k bits in each byte of (n+k) bits to be accessed with respect to counterpart minor loops of a sequentially accessed byte-organized major/minor loop memory array. The combination of bad byte location pointers and a byte mask is used to delete bits on bad bytes extracted from the memory or to insert zeroes into defective loop locations when bad bytes are written into the memory. Alternatively, the ith bit in each byte of (n+1) bits to be accessed may be modified through the utilization of the value of the ith bit written into the byte position of n+1st bit, while the ith bit of a defective byte position is zeroed. As a bad byte is extracted, the value of the n+1st bit is substituted for the ith bit. A dense list, rather than a sparse bad byte pointer list, is used.Type: GrantFiled: July 7, 1980Date of Patent: March 3, 1981Assignee: International Business Machines CorporationInventors: Abraham M. Gindi, Magdi R. Orfali, Arvind M. Patel

Patent number: T100405Abstract: A powdered orange flavor containing 27 fold orange oil adsorbed on rice sch was prepared by a menthol treatment process. The powder contained the equivalent flavoring potency of 18% by wt. of whole orange oil, which was the maximum obtainable; other rice starch samples contained lesser amounts and had lower folds. Two other edible polymers, egg albumin and Mor-rex (hydrolyzed cereal solids), also had some capacity, when treated with methanol, for polar orange oil components. These were less suitable than starch, however, because of inadequate concentration on the polymer, a low degree of folding, or distorted oil compositions.Type: GrantFiled: February 6, 1980Date of Patent: March 3, 1981Assignee: The United States of America as represented by the Secretary of the NavyInventor: Eric D.
