Title: Moving contact blade barrier
Inventor: QUINTON DON
IPC: H01H33/53
Filed: 1989-09-06
Granted: 1994-07-19
Abstract: ABSTRACT    A single piece contact barrier for separating and maintaining the spacing of the contact blades in a circuit breaker. The barrier is also adapted to form an insulating barrier between the contact blades and produce an arc quenching vapor.  Under certain circumstances, when one contact and its associated contact are separated, an arc is formed between the contacts.  The heat generated by the arc causes the barrier to vaporize in near the arc such that the vapor tends to quench the arc.

Abstract: ANHYDROUS DILUENTS FOR THE ISOBUTYLENE OXIDATION REACTION TO METHACROLEIN AND METHACROLEIN OXIDATION TO METHACRYLIC ACID                 ABSTRACT        The processes for oxidation of isobutylene to methacrolein and the oxidation of isobutylene to methacrylic acid in two stages with methacrolein as an intermediate are improved by use of essentially inert essentially anhydrous diluent gases to replace steam in the reaction streams.  In particular, the use of essentially inert essentially anhydrous diluents which raise the composite heat capacity of the diluent gas mixture to at least about 6.5 calories/(gram-mole) (°C) will improve selectivity to desired products and will reduce both the waste water load on the system and by-product formation.

Title: Combinatorial signatures for data encoding and searching
Inventor: CHANG WALTER W
IPC: G06F17/30
Filed: 1989-10-02
Granted: 1994-07-12
Abstract: This invention encodes information (such as the field values of a database record, or the words of a text document) so that the original information may beefficiently searched by a computer. An information object is encoded into a small "signature" or codeword using a method. A base or "leaf" signature S1 34 is computed by a known technique such as hashing. The logical intersection (AND) ofeach possible combination of pairs of bits of the base signature is computed, and the result is stored as one bit of a longer combinatorial signature CS1 42. The bit-wise logical union (bit-OR) of the combinatorial signatures of a group of records produces a second-level combinatorial signature CS2 52 representing particular field values present among those records. Higher-level combinatorial signatures CS3 60, CS4, etc. are computed similarly. These combinatorial signatures avoid a "saturation"problem which occurs when signatures are grouped together, and a "combinatorial error" problem which falsely indicates the existence of nonexistent records, thereby significantly improving the ability to reject data not relevant to a given query. When the combinatorial signatures are stored in a hierarchical data structure, such as a B-tree index of a database management system, they provide means for more efficiently searching database records or document text by eliminating large amounts of nonmatching data from further consideration.
