Title: Processes for recovering citric acid
Inventor: MCQUIGG DONALD
IPC: B01J41/04
Filed: 1992-03-12
Granted: 2002-10-29
Abstract: Described are preferred processes for recovering citric acid from a medium in which it is contained. The citric acid is rec-overed both effectively and in a form which is readily purifiable. In one preferred process, the citric acid-containing medium is contacted with a solid-phase free base resin having tertiary amine groups to adsorb the citric acid. The citric acid is then desorbed by displacement with a stronger acid, and a citric acid-containing fraction is collected substantially free from contamination by the stronger acid. In another preferred process, a citric acid-containing medium is contacted with a solid-phase polymer having pyridine functions to adsorb citric acid, the contacting being at a temperature below about 40°C. Adsorbed citric acid is then de-sorbed with hot H2O at a temperature of at least about 75°C.  Unnecessary impurities such as those arising from the use of organic solvent or throughput inorganic acid desorbents are thereby avoided while at the same time achieving a commercial-ly attractive recovery of the citric acid. Additional preferred modes and process features are also described.

Abstract: Formwork (1) for surfaces varying in curvature has a face sheet (2) adjustable with respect to its curvature, girders (3) supporting the face sheet and applied to the girders (3), in spaced relationship to the face sheet (2), there is a boom system which is composed of individual boom members (4,5) bridging the girders (3) and is suitably attached to the girders (3) at the outsides thereof averted from the face sheet (2). Adjustment of the curvature of the face sheet (2) is carried out by altering the effective length of the boom members (4,5) between the girders (3).      The mutually opposed formwork elements are adapted to be braced together by means of formwork anchor ties (6). A crosspiece (4) in the form of a boom member is applied to a formwork element at at least two girders (3) and simul-taneously serves as an abutment for the formwork anchor tie (6), the latter therefore being arranged between and having its reaction forces transferred to the two girders. The crosspiece is likewise changeable in its effective length by its fastening location being adjustable in the longitudinal direction in which the crosspiece extends and transversely to the orientation of the girder, so that the crosspiece (4) is available as an adjustable boom member in altering the curva-ture of the face sheet (2), as well as sustaining the tension forces.

Inventor: PAULSEN CRAIG A
IPC: G07F17/32
Filed: 1993-12-13
Granted: 1999-03-30
Abstract: SYSTEM, METHOD AND APPARATUS FOR GENERATING LARGE JACKPOTS ON LIVE GAME CARD TABLES                 ABSTRACT OF THE DISCLOSURE           A system to generate large (e.g. $1 million) jackpots for live card games such as blackjack is disclosed.          Multiple live card tables are placed in one or more gaming establishments.  A coin acceptor is assigned to each player position on the tables and includes a sensor for determining the presence of a coin to generate a signal indicating that a jackpot side bet has been placed and to correspondingly increase the available jackpot that is being accumulated from the side bets on all tables.  The coin acceptors are mounted directly to the playing tables.  The acceptors have a low profile above the table top and include sloping surfaces to facilitate the insertion and withdrawal of coins from them.          Each coin acceptor communicates with a central computer or processor.  The computer keeps track of jackpot accumulations, deducts winnings therefrom, controls strategically positioned displays to inform players and dealers of the size of the available jackpot or jackpots, and the table includes controls adjacent the dealer position to prevent late betting and pay winning players their jackpots.  To generate the large jackpots, blackjack is played with six full decks of cards, and winning blackjack hands are selected to have the requisite low probability of occurrence.

Abstract: The process and apparatus of the present invention enable the production of glass fiber product from scrap glass fibers. The invention includes: feeding the scrap glass fibers (14) having an average length up to around 12 inches to a glass melting tank (40) having a pool (36) of molten glass, melting the scrap glass fibers (14) without the presence of non-vitrified glass forming materials in an oxidizing environment, conditioning the melt to a formable viscosity, and forming the glass fiber from the conditioned melt where for a given glass fiber product the e is a near constant pull of the melted glass from the melter (40). The rate of feeding of the scrap glass to the melter is sufficient to maintain the pool of melted glass with a level within the range of + 0.35 inch (9 mm.) over a period of eight hours. The glass melter (40) has a high length to width ratio with a finite-sided melting containment area which holds a pool of molten glass (36) that receives the scrap glass.

Title: Capillary connector
Inventor: PICHA NEIL ROBERT
IPC: G01N30/60
Filed: 1995-09-11
Granted: 2001-11-20
Abstract: A capillary column connector assembly includes a pair of body members fabricated from a resilient, inert ceramic having high compressive strength. Each body member has an inwardly tapering longitudinal throughbore within which the end of a capillary column can be inserted by press-fitting. A split sleeve holds the two body members in mutually facing alignment with inner end surfaces in compressed mutual contact. The inner end surfaces are slightly radiussed in order to deform upon compression to provide a fluid-tight seal surrounding the junction between the inner ends of the longitudinal bores, thereby eliminating the need for any separate sealing gasket. A mechanical assembly comprising an inner spool, an outer housing, a spring, and a bearing-mounted support provide axial compression forces tending to urge the ceramic body members into mutual facing contact with the radiussed surfaces deformed.

Abstract: A protective barrier assembly for shielding a piercing element such as a pointedneedle cannula or blunt ended cannula during or after use of a medical implement. The piercing element includes a longitudinal axis, a length, a distal end which may be pointed or blunt, a proximal end and a passageway therethrough. The assembly may include a hub configured for mounting to a medical implement such as a syringe or evacuated tube holder and having an axial opening through it for receiving the needle so that the distal end of the needle projects outwardly. The assembly also includes a shield with an open end, a closed end, and a sidewall portion with a longitudinal slot extending from the open end toward the closed end The shield has a first position exposing the needle and a second position wherein the shield obstructs unintentional access to the needle. The shield may be mounted to the hub by a hinge opposite the slot, so that when the slot is moved from the first position to the second position, the slot provides clearance for the needle. A retaining and/or locking mechanism may be incorporated as part of the shield or made integral with the hinge so as to retain/lock the shield in the second position.
