Abstract: HOT WATER STORAGE TANK HEAT EXCHANGER SYSTEM                 ABSTRACT OF THE DISCLOSURE A heat storage system for a fuel fired prime mover driven space conditioner.  Rejected heat from the prime mover is advantageously stored in a storage type potable hot water heater.  Heat is transferred from a coolant fluid for the prime mover by forcibly circulating water from the tank of the potable hot water heater with a pump driven by the hydraulic energy of the coolant fluid.  Since the coolant fluid flows when the prime mover is operated, control circuitry for the water circulating pump is avoided.

IPC: G01G19/00
Filed: 1993-05-18
Abstract: LOCKING MECHANISM FOR A VIBRATING TRAY SCALE                  ABSTRACT OF THE DISCLOSURE        This invention relates to locking mechanism for a weighing scale capable of weighing flat articles at a high rate and with a high degree of accuracy.  The locking mechanism of the instant invention is applicable to a vibrating tray type scale which requires a mechanism for stabilizing the base of the scale during periods when articles are being conveyed onto and off the tray of the scale.  An electromagnetic locking mechanism has been conceived that provides advantageous for a vibrating tray scale.  These advantages are simple construction, low cost, self compensating and zero force requirement.  With a such locking mechanism, the vibrating tray scale functions more accurately and rapidly.

Abstract: A method for producing lower alkali glass wherein fluxing activity provided by alkali oxides is replaced by fluxing activity provided by water in the glassmaking process.  Water is effectively and efficiently provided to the glass by the establishment of a high water vapor concentration in the glassmelting zone atmosphere which is produced by a defined heat-generating oxygen-based combustion reducing nitrogen and boosting the water vapor concentration, and maintained in the glass by passing molten glass through successive refining and forehearth zones having atmospheres with high water vapor concentrations.

Abstract: A communication system dynamically assigns channels to a subscriber unit so as to, inter alia, mitigate the effects of co-channel interference in the system. The communication system has a plurality of base-stations (111, 112, 115, 118) receiving the transmission of a subscriber unit (120, 100, 121) desiring service. Upon receipt of the subscriber unit's transmission, each base-station determines a signal quality value, which it then reports to a system controller (210). The system controller determines the best signal quality value reported and assigns a channel o the base-station which reported the best signal quality value. The chosen base-station transmits to the subscriber unit on an assigned channel to establish communication. The assigned channel transmitted by the chosen base-station need not be associated with the channel the subscriber transmits on. In fact, either channel may be any one of the channels allocated for use by the communication system.

Title: Contoured tire building drum and method of building an extended mobility tire
Inventor: CONGER KENNETH D
IPC: B60C13/00
Filed: 1994-04-13
Abstract: Tire components are assembled on a tire building drum by laying a first liner on a surface of the drum, positioning first sidewall inserts below the cylindrical surface of the drum and around the drum at insert locations spaced from each end of the drum, laying a first carcass ply around the drum, positioning second inserts over the first ply at the insert locations, laying a second carcass over the first ply and the second inserts, positioning beads at each end of the drum, expanding the drum to increase the diameter of the cylindrical surface of the drum and provide shoulders at each end of the drum, turning edges of the first ply and the second ply over each of the beads, positioning a belt and tread assembly around the second ply, and contracting the drum for removal of the assembled tire components from the drum.      The inserts are positioned in grooves extending radially inwardly in the outer surface of the building drum. The grooves enable thick inserts to be built into the tire sidewall while still maintaining a generally flat outer surface of the tire while on the building drum, thereby decreasing the possibility of air trapped between components of the uncured tire.

Title: Novel steroid intermediates and processes for their preparation

IPC: A61P31/04
Filed: 1993-01-26
Abstract: Novel steroids having a 9.alpha.-hydroxy or a 9.alpha.-carbonate substituent can be prepared from 9.alpha.-hydroxyandrostenedione and can be utilized in the synthesis of commercially valuable corticosteroids such as betamethasone. The 9.alpha.-carbonates are prepared by reaction of the corresponding 9.alpha.-hydroxy steroid with a sequence of excess base, trialkylsilyl chloride, alkyl haloformate and alkanol or by using excess base, alkyl haloformate and alkoxide. 9.alpha.-Carbonate-17-keto compounds can be treated with lithium acetylide and a lithium salt to afford the corresponding 17.alpha.-ethynyl-17.beta.-hydroxy-9.alpha.-carbonate. This compound is then esterified with a novel series of reagents to give the 17-ester which can be reduced the corresponding 17-allene. Oxidation of this allene to the bis-epoxide compound, followed by treatment with an alkali metal salt of a carboxylic acid under phase transfer conditions gives 17.alpha.-hydroxy 21-ester 9.alpha.-carbonate.  Elimination of the 9.alpha.-carbonate group affords the a 17.alpha.-hydroxy, 9(11)ene, which in a few subsequent steps can be converted to a variety of commercially important corticosteroids. Novel 9.alpha.-carbonate compounds are prepared in the various reaction steps.
