Title: Edible film and method of using same for decorating foodstuffs
Inventor: STEWART DOUGLAS ROBERT
IPC: A23L1/00
Filed: 1994-07-06
Abstract: An edible film and method of using same for decorating foodstuffs, in particular and baked goods, wherein anyone can easily, inexpensively and artistically decorate foodstuffs.  The edible film according to the present invention is composed of an edible polymer film which is preferably releasably mounted upon a flexible substrate to provide a reinforced edible film.  The edible film is peelably released from the substrate to provide decorations for the foodstuff. The edible film may be decoratively prepared into predetermined decorations prior to distribution,  which may include being pre-printed, pre-cut, colored, or being of pre-selected opacity and sheen.  Pre-printing may be accomplished by any suitable printing process utilizing edible inks.  Alternatively, the edible film may be distributed in a not yet finalized decoration form, wherein finalization is left up to the user.  For example, the reinforced edible film may be distributed without being pre-printed or only partially pre-printed, wherein the user controls subsequent printing, writing, drawing or otherwise marking upon the edible film, such as by use of edible ink writing instruments.  Further, the user may purchase sheets of the reinforced edible film and thereafter cut the reinforced edible film sheets into shapes defined by the user.

Title: Temperature and volume control pressure balancing valve
Inventor: CLARE MANAMOHAN
IPC: F16K11/078
Filed: 1996-01-18
Abstract: An arrangement for temperature control and volume control of a pressure balancing valve used in tub/shower installations includes a temperature control handle that controls the mix of hot and cold water issuing from a pressure balancing cartridge within the valve and a volume control handle that controls the volume of the hot and cold water issuing from the cartridge. The volume control handle is connected to three lobes extending radially about the end of a shaft to which that handle is attached, the lobes being closely adjacent the face of the cartridge from which the water flows. The cartridge has a hot water outlet and a cold water outlet and in the neutral position of the volume control handle one of the lobes is located between the cartridge outlets and the other lobes do not block the outlets. When the valve is in operation one can rotate the temperature control handle to set the desired water temperature and one can rotate the volume control handle to set the desired water volume flowing from the cartridge. The two control handles are interconnected for conjoint movement so that when the temperature control handle is rotated to its "off" position to stop water flow the volume control handle is rotated back to its neutral position.
Patent CA-2167873-A1 (CA)
Inventor: FUKUOKA YUKO
IPC: H01M8/10
Filed: 1996-01-23
Abstract: The invention provides a method for manufacturing a solid polymer electrolyte electrolyte fuel cell which exhibits higher performances by sufficiently and uniformly contacting the solid polymer electrolyte with a catalyst to increase the reaction area inside the electrode. The method comprises the steps of dispersing a carbon powder supporting a noble metal catalyst in an organic solvent to obtain a dispersion, mixing the resulting dispersion with an alcoholic solution of a solid polymer electrolyte to produce a colloid of the solid polymer electrolyte and simultaneously to obtain a mixed solution in which said colloid is adsorbed to the carbon powder, applying the mixed solution on one side of a gas-diffusion layer to produce an electrode, and pressing the resulting electrode on at least one side of a solid polymer electrolyte membrane to integrate them. Furthermore, a fluorocarbon polymer can be added, to thereby form a gas channel without excessive covering of the catalyst and increase gas permeability of the electrode. Thus, a solid polymer electrolyte fuel cell which exhibits high performances in a high current density area can be further provided.

Title: Solidified Liquid Crystals of Cellulose with Optically Variable Properties
Inventor: REVOL JEAN-FRANCOIS
IPC: C09D11/00
Filed: 1995-02-09
Abstract: Solid films with novel optical properties are produced from colloidal suspensions of cellulose crystallites; the colloidal suspensions are prepared by acid hydrolysis of crystalline cellulose under carefully controlled conditions; the solid materials possess a helicoidal arrangement of the constituent crystallites, by appropriate selection of conditions for preparation and treatment of the colloidal suspensions, solid films are produced that reflect circularly polarized visible light; the wavelength of the reflected light can be controlled to give colours across the visible spectrum from red to violet and if necessary to infrared and ultraviolet wavelengths. The reflected iridescent colours arise from optical interference effects, and change with the viewing angle this makes the materials ideally suited for optical authenticating devices, since no printing or photocopying technique can reproduce this effect, furthermore, they are easily distinguishable from other optical interference devices since thay have additional optical properties.

IPC: H04W84/02
Filed: 1997-01-15
Abstract: A called party is alerted to the presence of a voice call on the Internet (110) by a page that is automatically transmitted to the called party's pager (120) upon initiation of the call by a calling party from his terminal (101) running Internet voice communications software and equipped with a microphone (102) and speaker (103). The page is transmitted in response to a message sent by a service provider (115) on the Internet, which receives from the calling party's terminal on the Internet, information for identifying the called party's pager. The called party, upon receiving the page, connects to the called party on the Internet through his home terminal (105) that is running that same voice communications software and is also equipped with a microphone (106) and speaker (107), or through any such similarly equipped portable or fixed terminal (125) at any location from which the Internet can be accessed. Alternatively, the called party can answer the call on the Internet with a standard station set (131 ) by calling an Internet-savvy platform (130), which converts the packetized voice signal of the calling party into an analog signal and the analog voice signal of the called party into packets for transmission on the Internet.
