Title: Multiple layer flexible sheet structure
Inventor: REDDING DWIGHT DENNIS
IPC: B32B15/085
Filed: 1984-02-28
Abstract: A multiple layer sheet structure (10) suitable for making tubular squeeze containers, such as for dentifrice, incorporates a uniaxially oriented polypropylene layer (16) within 1.5 mils (0.038 mm) of a surface of the structure destined to be the exterior of the container. Preferably the polypropylene is coextruded with low density polyethylene (12), and an intervening adhesive polymer (14) to form a three layer coextruded film substructure. The substructure is then uniaxially oriented at a stretch ratio of 3/1 to 4/1 and then laminated to the other layers (18 to 30) of the multiple layer structure, the low density polyethylene layer (12) forming one of the exterior surfaces of the sheet structure. Lap-seamed tubes are formed from the sheet structure with the uniaxially oriented layers (12 to 16) at the outer surface of the tube, and with the direction or orientation running along the length of the tube.

Title: A process for distinguishing nucleic acids on the basis of nucleotide differences
Inventor: LIVAK KENNETH JAMES
IPC: C12N15/09
Filed: 1991-03-14
Abstract: A process is provided for detecting polymorphisms on the basis of nucleotide differences in random segments of the nucleic acid by performing a primer extension reaction on the nucleic acids and comparing the extension reaction products. The random nucleic acid segment can be amplified by first dissociating the extension product from the template and contacting the dissociated extension product with a primer under conditions such that an amplification extension product is synthesized using the dissociated extension product as a template. Differences in the extension product are useful as markers in constructing genetic maps and as markers to distinguish or identify individuals.

Abstract: The present specification discloses a gas burner for a solid fuel effect gas fire. Certain such burners comprise a metal trough (3) with a gas/air mix supply pipe (7) extending through a wall of the trough (3), the open top of the trough (3) being closed by a ceramic plaque (17) which is formed with a number of simulated solid fuel elements (19) moulded in its upper surface and with a multiplicity of gas/air mix bores (15) extending therethrough. The ceramic plaque (17) sealed to the rim of the trough (3) by a suitable mastic or filler. However, with heat and age this sealant does deteriorate allowing leakage from the burner chamber via an undesired route. The present invention provides a burner (1) comprising an integrally formed metal casing (3,11) defining a gas/air mix chamber. A gas/air mix supply pipe (7) connects with the chamber and a number of burner bores (15) are provided in a wall (11) of the casing (3,11). Simulated solid fuel elements (19) can then be located above or on the said wall (11) of the casing (3,11) so as to not close said burner bores (15), age etc. not affecting the performance of the burner.

Title: Prepayment systems
Inventor: CLARKE DAVID JOHN
IPC: G07F7/12
Filed: 1993-11-30
Granted: 1998-04-15
Abstract: A prepayment commodity supply system for use in the supply of utilities such as electricity, gas and water to a customer comprises a prepayment token, typically a memory card or a smart card, into which credit data representative of an amount of credit or an amount of the commodity is entered by a vending machine in return for payment by the customer. The token is then inserted by the customer into a commodity supply control device, typically a meter, to enable the supply of an amount of the commodity determined by the credit data. The system includes simple (or "dumb") vending machines which are cheap enough to be installed in post offices, corner shops and the like, and each of which communicates by phone with a more sophisticated "special action partner". The special action partner periodically downloads a "grey list" of customers/tokens requiring some kind of special action to its dumb terminals, and each of the latter, on recognising a customer/token on the grey list, automatically contacts the special action partner, which then performs the special action via the dumb terminal. A particular special action is the creation of a duplicate token to replace a lost token, achieved by using an authorising code number which is given to the customer when he reports the loss and which is then entered into the dumb terminal along with a blank token to enable the special action partner to create the duplicate via the dumb terminal. <IMAGE>

Title: Filter
Inventor: SEO HIROFUMI
IPC: C02F1/42
Filed: 1995-09-28
Granted: 1998-04-15
Abstract: A method and apparatus for separating heavy metal ions from a processing solution includes a filter. A cylindrical separating member divides the filter into two discrete compartments, an inner cylindrical portion and an outer annular portion concentrically arranged outside the inner cylindrical portion. The separating member is made of chemical and heat resistant material. The processing solution is made to flow through the inner portion in one direction and a gas is made to flow through the outer portion in the opposite direction. The flowing has negatively charges the separating member, which results in formation of an electrical double layer on the surface where the processing solution contacts the separating member. The heavy metal ions in the processing solution, which ions are positively charged, are attracted and adsorbed to the negatively charged separating member, thus removing the heavy metal ions from the processing solution.
