Patent CA-2235571-A1 (CA)
Title: Unauthorized call defeat apparatus
Inventor: ROSEN HOWARD B
IPC: H04M1/677
Filed: 1998-04-22
Abstract: A call defeat device to prevent calling unauthorized numbers, such as long distance, 1-900 etc., which is adapted to prevent a caller from successfully dialing one or more predetermined digit strings on a touch tone telephone connected to a given telephone line by apparatus including a touch tone decoder coupled to the telephone line and a microprocessor/memory for storing and issuing predetermined unauthorized digit strings, if dialed on the telephone, designates that the call is to be defeated. A comparator compares each digit string dialed on the telephone to the predetermined digit strings, and, if a match is sensed, a dialer sends onto the telephone line at least one DTMF digit, such as a "#", which will defeat the call in progress. In a variant of the unauthorized call defeat apparatus, if an unauthorized digit string is dialed, a mode of operation can be selected in which an audio tone, falling outside the standard passbands of all tones representing dialed digits, is applied to the telephone line so as to "jam" and thus prevent any meaningful communication on the line. The invention can be implemented as a stand alone device or incorporated into a telephone.
Patent CA-2236061-A1 (CA)
Title: Tubular blanket and printing machine using tubular blanket
Inventor: HARADA TAKAO
IPC: B41N10/02
Filed: 1998-04-27
Abstract: The present invention relates to a tubular blanket which comprises a main blanket section having at least a portion coming into contact with a printing-made web and a remaining blanket section other than the main blanket section. The remaining blanket section has a thickness thinner than the thickness of the main blanket section. Thus, even if inks or paper particles are attached to a web absent area on a circumferential surface of the tubular blanket, it is possible to eliminate the influence from the attachment of inks or paper particles, and to make the web cut-off hard to occur, so that the interference with the use of the tubular blanket is preventable, thereby enhancing the economy and the working efficiency.

Title: Poly(vinyl alcohol) copolymer ionomers, their preparation and use in textile sizes
Inventor: HAYES RICHARD ALLEN
IPC: D06M15/263
Filed: 1996-12-12
Abstract: Compositions and textile sizes based on those compositions, which are particular poly(vinyl alcohol) copolymer ionomers, as well as blends of those ionomers with other sizing polymers are described. A process to prepare the ionomers is described. The compositions are poly(vinyl alcohol) copolymers which have carboxylic acid ionomer comonomer units. Sizes based on these ionomers are aqueous solutions of the ionomers or solutions of blends of them with other poly(vinyl alcohol) polymers which are not ionomeric, or solution/suspensions of the ionomers with various starches, or both. Desizing in either water or caustic solutions is generally far superior to comparable polymer blends which contain no poly(vinyl alcohol) copolymer ionomer.

Patent CA-2249712-A1 (CA)
Title: Improved process and apparatus for producing non-woven webs
Inventor: LU FUMIN
IPC: D01D5/12
Filed: 1996-08-12
Abstract: A process for producing a non-woven polymeric fabric web, such as a spunbond web, having filaments of 0.1 to 5 denier with equivalent production rates is described. A plurality of continuous polymeric filaments (F) is extruded from an extruder (22) and attenuated by a drawing unit (31) that includes a longitudinal elongated slot (32) strategically positioned at an optimum distance very close to the spinneret (26). A web forming table (90) is positioned below the drawing unit for collecting the filaments and forming the filaments into a non-woven fabric web. At startup, throughput is nominal, air pressure is below 20 psig, and the spinneret is positioned more than 100 cm away from the drawing unit. Gradually, throughput is greatly increased by simultaneously increasing air pressure while reducing the distance between the spinneret and the drawing unit. Coordinating the adjustment of the throughput with air pressure and distance reduction of the spinneret and the drawing unit produces the finest filaments at equivalent production or the same filament size at the highest production rate and lowest cost.

Patent CA-2255080-A1 (CA)
Inventor: HAYASAKA SHOJI
IPC: A23L27/00
Filed: 1998-05-13
Abstract: The present invention relates to chitin beads having a uniform and fine particle size and comprising microsporidian spores whose principal cell wall substance is chitin; chitosan beads comprising N-deacetylated chitin and having a uniform fine particle size; methods for preparing these beads; carriers comprising these beads; and a method for preparing microsporidian spores.      Microsporidian spores are proliferated in insect's bodies or cultured cells to obtain chitin beads having the uniform and fine particle size and whose cell wall substance is mainly composed of chitin. The chitin as the major cell wall substance is subjected to N-deacetylation to give chitosan beads. When the insect is a larva of domesticated silkworm, microsporidian spores are proliferated by orally or percutaneously inoculating the spores into the 2nd instar domesticated silkworm larvae in a concentration of 5 × 10 2 to 5 × 10 8 spores/ml, then the proliferated microsporidian spores are isolated from the bodies of the grown 5th instar domesticated silkworm larvae, followed by purifying the resulting spores to give chitin beads having the uniform and fine particle size and chitosan beads can be obtained from the chitin beads in the same manner used above. These beads are used as carriers for the immobilization or encapsulation of a variety of substances such as an antibiotic and a microorganism.
