Patent CA-2197233-A1 (CA)
Inventor: GLIMCHER LAURIE H
IPC: C12Q1/68
Filed: 1995-08-22
Abstract: Disclosed are methods of identifying compounds which inhibit transcription activation by CIITA and thus inhibit MHC class II gene expression. Such compounds can affect the induction of an immune response. The methods employ, independently, the activation and interactions domains of CIITA. The methods also employ the activation and interaction domains of isotype-specific CIITA  proteins, allowing for the identification of compounds which are isotype-specific inhibitors of transcription and which are useful for selectively affecting the immune system.
Patent CA-2199522-A1 (CA)
Inventor: KNITTEL GERALD H
IPC: F16L59/02
Filed: 1996-07-05
Abstract: The present invention relates to a combination of A and B adhesives (16 and 12 respectively) reacting together through a scrim material (14) in a laminated combination, and wherein the B adhesive (12) has great adherence characteristics to a vinyl nitrile foam (10), and the A adhesive (16) has great adherence characteristics to itself. Thus, a laminate of the A adhesive (16) / scrim (14) / B  adhesive (12) to each side of a slit in a vinyl nitrile foam tubular insulation (10), with appropriate release liners (18) covering the outside A  adhesive (16), has been found particularly effective. When the release liners (18) are removed and the A adhesives (16) are pressed together, a very strong bond is created closing the slit in the vinyl nitrile foam insulation (10) holding the tubular vinyl nitrile foam (10) in place on the tubular member to be insulated. Normally, this is utilized in an air conditioning application with the piping or tubes running from the compressor to the air conditioning unit, and wherein vinyl nitrile foam insulation has proven to be the best insulation material for this application.

Patent CA-2221964-A1 (CA)
Inventor: ODER RUBEN EARL III
IPC: A45D34/04
Filed: 1995-06-20
Abstract: La présente invention se rapporte à un applicateur à bille (10) conçu de façon à permettre aux gaz se trouvant entre la partie interne et la partie externe de s'échapper. Cet applicateur comporte une bille (3) siégeant dans un orifice (2) d'administration et un organe support flexible et résilient (4). Cet organe est conçu de façon à pousser la bille contre l'orifice d'administration, créant un contact étanche à l'eau entre la bille et l'orifice d'administration. Ce contact se fait de telle manière que la pression accumulée à l'intérieur du réceptacle n'est pas efficacement relâchée pour passer à l'extérieur du réceptacle. De plus, l'organe support flexible et résilient peut être déformé élastiquement par une force externe qui agit sur la bille et libère le contact étanche à l'eau entre la bille et l'orifice d'administration, ce qui permet au produit contenu dans le réceptacle d'être diffusé par la bille. L'applicateur comporte également un capuchon qui fait pression sur la bille, créant un passage libre (23) entre la bille et l'orifice d'administration uniquement au moment où il s'engage sur le réceptacle et/ou s'en dégage.

Inventor: LIPPONEN JUHA
IPC: D21G1/00
Filed: 1997-04-29
Abstract: Cette invention se rapporte à un procédé pour l'ouverture rapide des rouleaux d'un ensemble de rouleaux d'une calandre, en particulier une supercalandre. Dans une telle calandre (10), un ruban de papier ou de carton (W) à calandrer est amené à passer à travers les pinces de calandrage (N¿1?-N¿9?) formées par un rouleau supérieur à cambrure variable (13), par un rouleau inférieur à cambrure variable (14) et par au moins deux rouleaux intermédiaires (15-22) disposés entre les rouleaux supérieur et inférieur (13, 14). Les rouleaux (13-22) sont disposés de façon à former un empilement essentiellement vertical de rouleaux (12) et les rouleaux intermédiaires (15-22) sont soutenus au moyen de cylindres de décharge hydraulique (155-225), de façon à relâcher la charge de contact au niveau des pinces produites par les masses des logements de paliers (151-221) se trouvant au niveau des rouleaux intermédiaires (15-22) et des dispositifs auxiliaires (154-224) associés à ces rouleaux. Durant l'ouverture rapide des rouleaux de l'ensemble des rouleaux de cette calandre, le rouleau inférieur (14) de cet ensemble est abaissé et les pressions de décharge s'exerçant dans les cylindres de décharge hydraulique (155-225) sont relâchées, ce qui provoque l'ouverture des pinces de calandrage (N¿1?-N¿9?). L'huile hydraulique s'écoulant hors des cylindres de décharge (155-225) est régulée au moyen de valves connectées aux cylindres de décharge (155-225) de chaque rouleau intermédiaire (15-22), pour que, au moment de l'ouverture rapide des rouleaux de l'ensemble des rouleaux de la calandre, les pinces (N¿1?-N¿9?) dudit rouleau puissent être ouvertes de façon régulée dans l'ordre désiré. Cette invention se rapporte également à un système hydraulique pour un tel ensemble de rouleaux.

Title: Headbox of a paper machine with edge feed arrangements
Inventor: HUOVILA JYKI
IPC: D21F1/08
Filed: 1998-01-05
Abstract: A headbox of a paper machine which is provided with a dilution profiling system which uses a feedback-connected regulation system to control the cross-direction basis weight profile of the paper web produced by the paper machine. The dilution profiling system includes a feed header for a dilution liquid or for a stock suspension of a consistency lower than the consistency in the headbox, feed ducts fluidly coupled to the dilution header and regulation valves associated with the feed ducts for the dilution liquid, whereby the dilution liquid is passed to an area between a front wall of the inlet header of the headbox and a slice duct of the headbox. In the dilution profiling system, edge feed arrangements are integrated in both lateral areas of the headbox. The edge feed arrangement include ducts by whose means it is possible to pass edge flows from the inlet header of the dilution profiling system into both of the lateral areas of the headbox, which edge flows have velocities and/or mutual velocity ratios that can be set and/or regulated. By means of the edge flows, a controlled transverse velocity component is produced in the stock suspension jet so as to control the cross-direction fiber orientation profile.

Title: Water filter with pressure actuated flow monitor
Inventor: ZABINSKI JOHN
IPC: C02F1/00
Filed: 1998-05-11
Abstract: A faucet mounted water filtration system with a filter life monitor includes a filter housing with a flexible cap which deflects upon introduction of water into the housing. The deflection of the cap closes a switch on an electrical circuit which counts the time the water is flowing through the housing. Once a predetermined amount of time accumulates, the circuit generates a message to inform the user that the filter needs replacement.

Inventor: WOLF JOHANN
IPC: E04C2/12
Filed: 1998-09-15
Abstract: Known structures of solid wood have horizontal layering of the beams. Due to the often not inconsiderable length of the walls, short pieces can only be used in the area of the windows and doors. Since however in forestry large amounts of thin lumber are formed for which there is no feasible use,  and since the paper industry can only handle a fraction of this wood, it is proposed that solid wooden  beams   (2)   are  arranged  vertically  in  the installation position of the prefabricated wall panel. Since the height between floors in buildings is usually only between 2.5 and 3 meters, short pieces which have only a corresponding length can be easily used for this purpose. The solid wooden beams (22) have at least one mortise (28) running in the lengthwise direction with a depth which is at least the width of the solid wooden beams (22) measured in the direction of the mortise (28). The growth rings of the beams (22) are cut by the mortises (28) such that the wood can "work" after installation of the solid wooden beams  (22)  in the prefabricated wall panel so that high stresses in the solid wooden beams (22) and consequently warping of the prefabricated wall panel are prevented.
