Title: Portable validation unit for gaming system
Inventor: RICHARDSON JOHN
IPC: A63F3/06
Filed: 1987-01-13
Granted: 1991-05-28
Abstract: ABSTRACT OF THE DISCLOSURE         A portable validation unit for an electronic gaming  system,  particularly a  bingo  system.   The validation unit communicates through a serial data interface with a base station of the gaming system to receive  a  serial  number  defining  a  particular validation unit and corresponding employee, and further receives a validation code defining a particular gaming schedule.    As  the  gaming  schedule  is  played on electronic bingo cards, wins of each game are validated by connecting a validation unit to an electronic card to ensure that the card has a matching validation code stored therein for the current gaming schedule and is indicating a winning sequence of called numbers.  If there is no winning indication, then the validation unit sounds one of two audible tunes depending upon whether the validation codes match.  In response to a matching  validation  code  and  win  indication,  the validation unit will sound another short recognizable audible tune  indicating a win.   If a bingo card contains provision for more than one type of win, such as an instant bingo, then different tunes are used to distinguish between win types.  There is additionally provided circuitry for transferring a win record stored in a bingo card to the validation unit during the validation process.  Another aspect of the validation unit provides for sounding another distinguishable audible tune if the validation unit memory is full instead of transferring a record.  At the end of the gaming schedule,  the validation unit is adapted to transfer the win records to the base station during an audit process.

Title: High drug:lipid formulations of liposomal- antineoplastic agents
Inventor: MAYER LAWRENCE D
IPC: A61K31/65
Filed: 1988-02-29
Granted: 1996-11-12
Abstract: A method for encapsulation of antineoplastic agents in liposomes is provided, having preferably a high drug:lipid ratio. Liposomes may be made by a process that loads the drug by an active mechanism using a transmembrane ion gradient, preferably a transmembrane pH gradient. Using this technique, trapping efficiencies approach 100%, and liposomes may be loaded with drug immediately prior to use, eliminating stability problems related to drug retention in the liposomes. Drug:lipid ratios employed are about 3-80 fold higher than for traditional liposome preparations, and the release rate of the drug from the liposomes is reduced. An assay method to determine free antineoplastic agents in a liposome preparation is also disclosed.

Abstract: Abstract of The Disclosure In a digitizer system, adjacent conductors in pairs are looped through four quarter sections of a grid active area in such a way that the unexcited polarities of the pair are different in each quarter section.  A coil in a pen tip is moveable relative to the grid, and used to inductively couple signals in the conductors of the grid.  The number of conductors required to span a given grid active area, and the number of multiplexers required to handle such conductors, are reduced by a factor of four.  The polarities of signals induced in the conductors by the coil are selectively changed depending upon the quarter section in which the coil is located and sampled to coarsely locate the coil as being between two particular adjacent conductors. in the disclosed embodiment, a ratio of the magnitudes of the signals induced in the two particular conductors is then used to precisely locate the coil between these two adjacent conductors.

IPC: B29C70/52
Filed: 1988-04-22
Granted: 1993-12-28
Abstract: ABSTRACT IN-LINE CORE-FILLED PULTRUDED PROFILES        In the manufacture of an in-line cored pultruded profile, filler is bonded with polyester or methacrylate type resin and encased in fibreglass, carbon or aramid fibre cloth 14, 14A. The cloth 14,14A is preformed to replicate the desired profile shape by means of a pre die former 15 and the external surface of a hollow duct 13. Filler is delivered into the interior of the duct 13 by a variable output venturi blower 12.  Precise distribution of packing is effected by the internal configuration of the duct 13 and the creation of a raised moving wall when non foaming resin is used.  Precise configurations of ducts can be achieved by fashioning from reinforced cloth.  Adjustable start drums 19 provide time and labour saving benefits.  Complete resin wet through using either foaming or non-foaming resin ensures excellent filler bonding and surface finish.
