Title: Light traceable transmission conduit assembly
Inventor: DUMONT KENNETH R
IPC: G02B6/38
Filed: 1995-02-13
Abstract: A traceable  transmission  conduit  assembly  includes  an optically transmissive jacket over a transmission conduit. The conduit, which may be an optical fiber,  includes a light transmissive and translucent jacket thereover.  Light is injected into the jacket at one location therealong.

Title: Separation of phytate from plant protein using ion exchange
Inventor: HOGARTH ARTHUR JAMES CLANCEY L
IPC: A23J1/14
Filed: 1993-08-09
Abstract: A process for the removal of phytate from protein using ion exchange has been developed. The process involves the upflow passage of a protein slurry at an elevated temperature through a strong base anion exchanger in the chloride form. The weak base anion sites inherent to the resin have been converted to the free base form. The anion exchange material can easily be regenerated. The process can be used on-line, yields phytate removal of greater than 90 %, has high (greater than 90 %) protein recovery, is cost-effective, and is environmentally friendly.

Title: Selectively actuatable lighter
Inventor: MCDONOUGH JAMES M
IPC: F23Q2/16
Filed: 1993-10-22
Abstract: A selectively actuatable lighter device (10) is disclosed which includes a body defining reservoir (12) for containing a com-bustible gaseous medium such as butane, and having a valve (20) arranged to be selectively actuated between a normally closed position and an open position which permits the exit of the gaseous medium.  Such lighter (10) can selectively produce sparks at a location (19, 22) proximate to the gaseous medium exit to ignite the gaseous medium. Such lighter device (10) embodies a resi-liently releasable valve actuator (14) which normally prevents actuation of the valve (22). The valve actuator (14) includes an inter-fering portion (14A) which is selectively movable to a position out of interference with an interfering portion (12B) of the lighter body, so that the gaseous medium may be released and ignited by the sparks.  Once the valve actuator (14) is depressed and re-leased, it returns to its closed or latched position to prevent actuation of the valve to the open position. To "re-use" the lighter, the valve actuator (14) must again be moved to an unlatched position so that the valve (22) can be actuated for subsequent ignition of the gaseous medium.

Title: Anti-flood protection feature for "heat pump" pool heaters
Inventor: ROBICHAUD GUY
IPC: F25B49/00
Filed: 1996-03-08
Abstract: In all pool heaters, the most vulnerable piece is always the heat exchanger tube. This is the tube that brings the heat and which is always in contact with the pool water. With time the tube will wear by erosion and/or corrosion, to a point where the water will penetrate the tube, so the tube must be changed. In general the repair will be limited to this area for Gas or oil pool heaters. But in the case of "Heat Pump" Pool Heaters, the tube that brings the energy is in reality a part of the freon closed circuit. When the leak is large enough to let the Freon pressure to drop under the pool water pressure, the water will get inside the freon circuit and in most cases will reach the compressor before the owner noticed anything abnormal with is Pool Heater. When this happened, the repairs are normally more expensive than the price of a new Pool heater. In the present invention, an electrical feature is added to the pool heater in such a way that water will stop circulating in the pool heater at the second that a drop in freon pressure is detected. This can easily be achieved by installing an electrical feature to control the electrical tine of the water pump motor, or it could control an optional Solenoid 3 ways valve that could divert the water directly in the pool when the drop of pressure in the heat pump freon circuit is sensed. So this way we stop the water flow in the pool heater at the second the drop of freon pressure had been detected. This new feature can be installed at the factor, as part of the internal electrical system or it can be added on any existing "Heat pump" pool heater as an external unit.

Filed: 1996-05-06
Abstract: A method and device for enhancing the vapor sterilization of the lumen of medical instruments and like articles under reduced pressure. A vessel containing a small amount of a vaporizable liquid antimicrobial solution is attached to the lumen. The antimicrobial vaporizes and flows directly into the lumen of the article as the pressure is reduced for the sterilization cycle. Preferred embodiments illustrate a sealed chamber containing the antimicrobial and an opener for opening the chamber with the device already attached to the article. Preferably, the opener comprises a hollow spike. A ring between the opener and chamber must be removed prior to opening the chamber and removal of the ring destroys the ring so that it can not be replaced.

IPC: C25F1/04
Filed: 1994-11-17
Abstract: An ultrasonic agitator ( 10) for generating turbulence in the vicinity of elongated metal workpieces (12) such as newly formed strands of wire. The system includes a bath (14) that is filled with a cleaning solution (16) The workpiece is introduced into the bath so as to move along a predetermined path of travel. One or more transducers (20,24) are disposed in the bath to produce ultrasonic waves in the cleaning solution. The transducers are further configured and spaced so that the focal points of the vibrations substantially coincide with the path of travel with the workpiece. The transducers are driven by a signal generator (28) that causes the transducers to vibrate at a frequency between 0.5 and 3.0 MHz. The vibrations of the transducers produce ultrasonic waves that can be used to scrub off contaminants from the surface of the workpiece.

Title: Pressure compression mould for the production of tires
Inventor: SOLBERG THOR
IPC: B29C43/10
Filed: 1995-07-03
Abstract: A pressure compression mould (30) for the production and/or revulcanisation of tires (10) where the compression mould forms a mould hollow space (34) where the pressure (P1) and the temperature can be regulated, and also where each of sidewall mould portions (36a, 36b) of the compression mould are designed with an elastic and flexible annular disc membrane which the sidewalls (14) of a tire placed in the mould is made to thrust against in order to control the outwardly directed tensile forces in the tire (10), is characterized in that at the membrane sides facing towards the mould hollow space (34) of the mould (30) is equipped with an annular disc-shaped membrane-protective plate in order to prevent direct contact between side faces of the tire and the respective membranes during the production/vulcanisation. The plate is split up, both in the radial and circular plane, into a series of smaller plates the free ends of which mutually overlap each other. When a tire is placed in the mould and the mould hollow space is pressure set, the sides of the tire are pressed outwards towards the plates which flex afterwards and furthermore the membrane is flexed outwards and is stretched. Thereby the direct contact between membrane and sides of the tire is avoided so that the sides of the tire are not vulcanised fast in the membrane, and the necessary flowing out of unvulcanised rubber is achieved.

Inventor: JOHNSON STEPHEN G
IPC: H04N19/94
Filed: 1995-07-14
Abstract: A system and method is disclosed that compresses and decompresses images. The compression system and method (126, 128, 130, 132) includes an encoder (130) which compresses images and stores such compressed images in a unique file format, and a decoder (110) which decompresses images. The encoder (130) optimizes the encoding process to accommodate different image types with fuzzy logic methods (152) that automatically analyze and decompose a source image, classify its components, select the optimal compression method for each component, and determine the optimal parameters of the selected compression methods. The encoding methods inlcude: a Reed Spline Filter (138), a discrete cosine transform (136), a differential pulse code modulator (140), and enhancement analyzer (144), an adaptive vector quantizer (134) and a channel encoder (132) to generate a plurality of data segments that contain the compressed image. The plurality of data segments are layered in the compressed file (104) to optimize the decoding process. The first layer allows the decoder (110) to display the compressed image as a miniature or a coarse quality full sized image, the decoder (110) then adds additional detail and sharpness to the displayed image as each new layer is received. The decoder (110) uses optimal decompression methods to expand the compressed image file.
