Title: Process for treating water-soluble dietary fiber with beta-glucanase
Inventor: SMITH JOHN J
IPC: A23L7/104
Filed: 1993-07-19
Abstract: The present invention relates to an improved process for producing a water-soluble dietary fiber composition wherein an aqueous dispersion of a gelatinized, milled, beta-glucan containing grain-based substrate is treated with alpha-amylase under conditions which will hydrolyze the substrate and yield a soluble fraction and an insoluble fraction, said soluble fraction is separated from said insoluble fraction, and said water-soluble dietary fiber is recovered from said soluble fraction substantially free of water-insoluble fiber, wherein the improvement to such process comprises treating beta-glucans released from the grain-based substrate with beta-glucanase under conditions which will hydrolyze the beta-glucans. The present invention further comprises dietary fiber compositions produced by the above-described process and a method of preparing edible food compositions containing the dietary fiber compositions produced by the above-described process.

Title: Method for recycling plastic coated paper product waste and polymeric film
Inventor: BROOKS JOE G
IPC: D21B1/32
Filed: 1992-03-20
Abstract: A method for reclaiming plastic from plastic waste material, including hydropulper or polymeric film and contaminants such as cellulosic fiber, adhesive labels, paper, dirt, or organic material.  The plastic waste material is reduced in size to particles having a maximum dimension ranging between about 1 inch and 8 inches. A  portion of the contaminants, including cellulosic fiber is mechanically separated from the plastic waste. Another portion of the contaminants is separated from the plastic by washing. The particle size of the plastic is further reduced to a maximum dimension of about 1/2 inch while in a wet slurry. Flotation with agitation further separates cellulosic fiber from plastic. The plastic is dewatered and dried to a moisture content of less than about 10 weight percent. The dried plastic is then rolled into pellets in a controlled low heat pelletizer.

Title: Tape cartridge and printing device
Inventor: TAKAYAMA MASAJI
IPC: B26D7/02
Filed: 1993-10-13
Abstract: ABSTRACT OF THE DISCLOSURE    The present invention provides a novel structure of a tape cartridge accommodating a printing tape and an ink ribbon used for printing, which prevents the printing tape from being stuck in a cartridge case or the ink ribbon from being slackened.  The tape cartridge of the invention has a mechanism for preventing an end of the tape from being reversely moved back into the cartridge case.   A typical structure of the mechanism includes an anti-inversion system which prevents a tape core having a tape wound thereon from rotating  in  a  reverse  direction,  that  is,  a  direction opposite to a normal rotating direction for printing.  The anti-inversion effects are removed when the tape cartridge is set in a printing device such as a tape writer to ensure smooth feeding of the tape for printing.  When the tape is forcibly pressed back into the cartridge case,  a movable platen clamps the tape between the platen and a fixed wall to prevent reverse movement of the tape.  The tape cartridge of the invention also includes an anti-slack mechanism for preventing slack of the ink ribbon through engagement of a ribbon winding core with an anti-rotational engagement piece.          Engagement of this anti-slack mechanism is also released when the tape cartridge is set in the printing device.

Patent CA-2114091-A1 (CA)
Inventor: VOGLER MICHAEL N
IPC: G09F15/00
Filed: 1994-01-24
Abstract: A unitary injection-molded plastic holder frame for displaying an advertising placard or the like has four frame sides connected at their ends into a rectangle, a contiguous trio of the sides having  generally  coplanar  mutually  directed  shallow  channels therein for receiving the side margins along three sides of the placard with the remaining frame side being slotted along its length to separate that side into two parallel frame strips.  The slot  is  in  coplanar  relation  to  said  shallow  channels  and communicates  at  its ends with the corresponding ends  of the channels in two opposite frame sides whereby the placard can be inserted via the slot into the frame with the margins of its three sides protruding into said channels.  Detent means is provided for positively retaining said placard in its inserted position within said frame, in the form at least one nib carried on an inner face of at least one of the frame strips projecting toward the opposite strip substantially into contact with the inner face of said opposite strip face and preventing the accidental passage of said placard through said slot.  Preferably, each nib has an inclined edge extending from a point adjacent the inner side of the frame strip to a point adjacent its outer side and sloping  in the direction from the inner to the outer side toward the opposite frame strip, the inclined edge facilitating the intentional passage of the placard past the nibs for removal from the frame.

Title: Par-aligner
Inventor: BRODIE JAMES D
IPC: A63B69/36
Filed: 1994-02-25
Abstract: Many people who engage in athletic activities have found that practising with the help of training aids can help to improve their performance.          Golfers often experience difficulty in achieving proper alignment of their feet with respect to both the position of the golf ball and to the intended line of flight of the ball.          For proper alignment two things are necessary: 1. The feet should be positioned or aligned so that a line projected through the heels goes to the target or is parallel to the desired flight line of the ball. 2. The ball should be positioned properly relative to the feet.           The PAR-ALIGNER is designed to help golfers to improve their ability to attain proper alignment.
Patent CA-2116866-A1 (CA)
Title: Circuit for detecting firing of an ultraviolet detector tube
Inventor: PETERSON SCOTT M
IPC: F23N5/08
Filed: 1992-12-04
Abstract: A driver circuit for an ultraviolet detector (UV) tube discriminates between firing of the UV tube in response to ultraviolet radiation impinging on it and a high resistance short between its output terminals. A capacitor charged on half cycles of AC power applied to the circuit discharges partially when the UV tube fires.  This charge is transferred to a second capacitor to create a voltage displaced from ground. Each time the UV tube fires, the steep wave front generated thereby is passed by a high pass filter to a switch which momentarily grounds the voltage on the second capacitor through a resistor. The rapid change in the switch element's voltage signifies the presence of ultraviolet radiation on the UV tube.

IPC: A01H4/00
Filed: 1993-03-29
Abstract: In a method of micropropagation, certified plants (1) received in tubes (2) are divided to provide nodal and apex cuttings (3, 4).  These cuttings are planted in an agar gel (5) containing macro-and micro-nutrients in a tray (6), and enclosed in plastics sheeting (7) for growth under high photo photon flux and carbon dioxide enriched conditions to provide microplants. The microplants are divided to provide nodal and apex cuttings (8, 9), of which the apex cuttings (9) are replanted in a foam substrate (11) and again enclosed in gas and vapour permeable plastics sheeting (13) for further growth, again in a high photo photon flux and enriched carbon dioxide environment. Cyclic repetition of initially growth on agar and subsequently growth on substrate enable very substantial numbers of genetically consistent plants to be grown. In a final stage of the process, cuttings (16) taken from the growth arrays (14) which develop within the enclosures (13) are transferred for planting out in a substantially natural environment.

IPC: H04W16/16
Filed: 1994-06-17
Abstract: In a mobile communication system of the present invention, a cordless base unit LBU is connected to a wired subscriber line SL. The base unit LBU detects a radio channel assigned to a cell other than a cell where the base unit LBU is located, among radio channels assigned to the cells of a cellular radio communication system. This radio channel is used as a radio channel for a cordless call. On the other hand, a cellular cordless telephone CCT is provided with a mode switch. When a cordless mode is designated by the mode switch, a radio channel for a cordless call is detected, as with the case of the base unit LBU. At the time of the cordless call, a transmission power level of the cellular cordless telephone CCT is set at a weak level smaller than that for a cellular call.
