Patent CA-2267944-A1 (CA)
Title: Moulded article-shapes
Inventor: CLARKE PETER REGINALD
IPC: B29C45/00
Filed: 1997-10-16
Abstract: An eye bath (470) has a thin wall (471) and a hollow annular rim (472). This was formed in an injection mould too] with a tear drop cross-sectional shape (473) - shown at one side - around the wall as a pre-form of polypropylene material mixed with blowing agent.  On mould opening before the material has solidified in the tear drop, this expands to circular cross section with a circumferential length (474) equal to that of the tear drop (475). This results in a slight fore-shortening of the height (476) of the eye bath from the height of the pre-form (477).

Title: A class of low cross correlation non-palindromic synchronization sequences for code tracking in synchronous multiple access communication systems
Inventor: COX TIMOTHY F
IPC: H04J13/00
Filed: 1997-10-29
Abstract: In a star configured multiple access radio communication system wherein a hub station communicates, in time division multiplex mode with a plurality of remote subscriber stations by a forward link signal path and the remote subscriber stations communicate with the hub on a return link that has multiple RF carriers that are configured in an orthogonal manner and wherein all received return link signals are time synchronous, and all signals possess the same time division multiplex structure in which a portion of the signal is dedicated to time synchronization. A synchronization burst sequence generator at each subscriber station, assuming that the time tracking and synchronization process of each return link is relatively unaffected by all other remote stations, generates a sync burst sequence including Sync Codes. The Sync Codes are constructed using a basis sequence of length N, b0, b1, ..., bN-1, with each element in the basis sequence drawn from a binary alphabet {-1,+1}.
Patent CA-2272412-A1 (CA)
Inventor: RIERA FRANK J
IPC: B05C1/06
Filed: 1999-05-19
Abstract: A system for applying adhesive to the peripheral edge of a window glass includes a brush which is held stationary while the window glass is moved with respect to the brush to apply the adhesive. The brush includes a plastic sleeve which exposes only a specified portion of the bristles of the brush. After the bristles have worn, the brush is moved to a cutting station where a portion of the sleeve is removed to expose another portion of the bristles. This operation continues until there is no material left on the sleeve to trim. At this point, the brush is discarded and replaced with a new brush automatically. Rather than have the window glass move with respect to the brush, the brush can be moved with respect to the window glass if desired.

Title: Procede et appareil de transmission et de reception de donnees de code concatenees
Inventor: WOLF JACK K
IPC: H03M13/47
Filed: 1997-12-19
Abstract: Dans des données de code concaténées, des mots de code décodés correctement provenant d'un décodeur de blocs sont utilisés pour améliorer le rendement du décodeur convolutionnel. Un mot de code peut parfois être décodé correctement avant réception de tous les symboles du mot de code. Un décodage précoce du mot de code permet la recréation correcte du mot de code entier, même des symboles n'ayant pas encore été reçus. Le mot de code entier corrigé est utilisé par le décodeur convolutionnel afin d'éliminer les dérivations du treillis, améliorant ainsi le décodage de bits d'informations antérieures et de bits d'informations futures dans le treillis. La distance inverse de chaîne du décodeur convolutionnel peut également être raccourcie sur la base de la connaissance que certains des mots de code reçus ont été décodés correctement. Enfin, les symboles de parité n'ayant pas encore été reçus pour le mot de code décodé correctement peuvent être éliminés de la transmission afin d'améliorer le débit de transmission global.

Title: Method and kit for detecting dna mutations using restriction enzymes
Inventor: BILITEWSKI URSULA
IPC: C12Q1/68
Filed: 1997-09-10
Abstract: The invention relates to a method for detecting DNA mutations using restriction enzymes. One condition to implement said method is that the cleaving performance of the selected restriction enzyme changes due to mutation. The relevant DNA segment in the genome containing the mutation is multiplied by means of polymerase chain reaction (PCR), wherein the primers used can each be labeled. The first primer enables the segment to be bonded to the surface of the carrier; the label of the second primer is used to enable detection. A restriction enzyme is incubated with the PCR amplicon, wherein the mutated segment is not cleaved if the cleavage site is suppressed by mutation. After the segments are bonded to the surface of the carrier, a detection reaction takes place, wherein the marking label of the second primer is removed in the wild type, insofar as it can be identified in the mutant. A  plurality of labels enabling direct or indirect detection is possible. This provides a rapid method for detecting specific mutations in the genome without resorting to complex conventional methods.

Abstract: A method of manufacturing a double walled vessel is herein disclosed. The method involves the steps of forming an outer vessel having at least one reassembly channel formed therearound and forming an inner vessel having at least one element fitting formed integral thereto. At least one control housing is secured to the outer surface of the inner shell in registration with the element fitting.  Heating elements and other control apparatus are installed in the element fittings within the control boxes. The outer vessel is sectioned at the reassembly channel, thereby allowing the inner vessel to be inserted into the outer vessel. The outer vessel is reassembled to enclose the inner vessel therein and a curable foam material is injected into the space between the inner and outer vessels to maintain a constant spatial relationship therebetween and to ensure the structural integrity of the outer vessel. Finally, a portion of the wall of the outer vessel corresponding to an open face of the control housing is removed to permit access to the interior of the control housing through the wall of the outer vessel.
