Patent CA-2190823-A1 (CA)
Title: Acoustic system
Inventor: MCCULLER MARK A
IPC: H04R1/28
Filed: 1996-11-20
Abstract: The present invention is directed toward an acoustic system for producing sounds over a broad range of frequencies. The acoustic system includes an enclosure, a speaker that is acoustically connected to the enclosure, for generating, almost simultaneously, two sounds, a forward sound, and a rearward sound. It further includes a waveguide enclosed at least partly within the enclosure, and acoustically connected to the speaker, for defining an acoustic path along whichone of the forward or rearward sounds travels. The waveguide includes a plurality of inner panels that are positioned inside the enclosure for optimizing the length of the acoustic travel path. The inner panels and the enclosure defining a plurality of inner passageways have generally similar cross-sectional surface areas, and a plurality of inner openings, cause a selective cancellation of sounds at predetermined frequencies, while preserving sounds at other frequencies. The present acoustic system design has numerous commercial applications. For instance, it can be used in conjunction with ultra sound and sonar systems, hearing aids, stethoscopes, microphones, telephones, hearing aids, and noise cancellation devices, radios, etc.

Title: Nco-terminated vinyl telomers
Inventor: LOHMANN DIETER
IPC: G02B1/10
Filed: 1995-12-27
Abstract: The invention concerns NCO-terminated vinyl telomers which are particularly suitable for use as surface-modifying agents and as coating materials, but also in the production of polymerizable compounds or block copolymers which react to give polymers which can be used to manufacture moulded articles, in particular contact lenses. The NCO-terminated vinyl telomers proposed are compounds of formula (I) O=C=N-PI*-(-A-)-p-Ra in which PI* is a bivalent photoinitiator group; A is a bivalent substituted 1,2-ethylene group derived from a copolymerizable vinyl monomer by replacing the vinyl double bond by a simple bond, each of the Ra groups, independently of each other, is a monovalent group suitable for use as chair terminator in a polymerization reaction; and p is a whole number from 3 to 500. The vinyl telomers carrying the NCO groups are of use in the production of macromers as well as block, comb, star and graft copolymers, preferably for the manufacture of contact lenses. These telomers are also of use in coating various types of surface, in particular the surfaces of contact lenses.

Inventor: VRIJSEN MARC JOSEPH MARTIN
IPC: A22C11/02
Filed: 1997-11-12
Abstract: A method and an apparatus which permit continuous stuffing of tubular food casing without stopping the stuffing operation to replace food casing on the stuffing horn. The method comprises placing a first shirred food casing strand onto a stuffing horn. An end portion of the food casing is then extended over the open end of the stuffing horn and the end portion is closed. The stuffing horn is suspended within the food casing by means of a first suspension means engaging the outer surface behind the shined food casing and foodstuff is injected into the stuffing horn through a hole in the first suspension means which mates with a first inlet hole in the stuffing horn so that foodstuff flows through the stuffing horn into the food casing. A subsequent food casing strand is then placed onto the stuffing horn over the stuffing horn closed end and the stuffing horn is clamped by means of a second suspension means engaging the stuffing horn behind the subsequent food casing strand. Foodstuff is then injected into the stuffing horn through a hole in the second suspension means which mates with a second inlet hole in the stuffing horn so that foodstuff flows through the stuffing horn into the food casing. The first suspension means is then disengaged so that the stuffing horn is suspended by said second suspension means and the first hole in the first suspension means. The strands are connected together. The first suspension means is engaged when sufficient casing has been used so that the subsequent strand passes the first inlet hole and the subsequent strand replaces the first strand. Foodstuff is then again injected into the stuffing horn through the first suspension means, the second suspension means is disengaged and another subsequent food casing strand is placed onto the stuffing horn over the stuffing horn rear end. The above steps are repeated for so long as stuffing of food product continues. The apparatus comprises means for practicing the steps of the above method.

Inventor: TANNO MOTOHIRO
IPC: H04W68/02
Filed: 1997-11-12
Abstract: A paging scheme for a mobile communication system which is capable of suppressing the power consumption of the mobile station by reducing the intermittent ratio while keeping an average time required for the paging shorter than a case of merely increasing a number of time-slots. Each base station transmits a paging channel on which a paging signal for each mobile station is transmitted at intermittent timings, where the paging channel has a data transmission rate higher than a required paging channel rate of the mobile communication system, so as to shorten a transmission time of the paging signal for each mobile station. Then, each mobile station judges a presence or absence of the paging signal for that mobile station by receiving the paging channel at these intermittent timings. The paging channel may have a data transmission rate which is variable. A number of time-slots provided in each frame of the paging channel can be increased so that an intermittent ratio at each mobile station becomes lower, without causing an increase of the average time required for the paging.
