Patent CA-2201783-A1 (CA)
Inventor: LATTNER JAMES RICHARDSON
IPC: C07C6/12
Filed: 1995-10-06
Abstract: On produit de l'éthylbenzène à partir d'éthylène dilué et de benzène dilué en trois étapes. D'abord, on alkyle l'apport de départ de benzène, qui contient du benzène, avec l'apport de départ d'éthylène, qui contient de l'éthylène, pour former, conjointement avec des polyéthylbenzènes (PEB), un éthylbenzène contenant un mélange de di et triéthylbenzène pouvant également contenir des tétra, penta et hexaéthylbenzènes. On distille ensuite le produit de la première étape pour enlever le benzène n'ayant pas réagi et toute autre substance n'ayant pas réagi. On récupère une partie de l'éthylbenzène par distillation. Dans une troisième étape, on procède à la transalkylation des polyéthylbenzènes à excédent de benzène pur pour former de l'éthylbenzène fini que l'on peut récupérer par distillation. On peut également appliquer ce procédé dans lequel on utilise une charge d'apport de benzène dilué à la fabrication de cumène plutôt que d'éthylbenzène, au moyen d'un apport de départ de propylène dilué plutôt que d'éthylène dilué. Les catalyseurs utilisés pour la phase d'alkylation et de transalkylation sont des catalyseurs à hétéropolyacide supportés tels que des catalyseurs à acide phosphotungstique sur un support de silice ou à zéolite Y sous forme acide.
Patent CA-2202820-A1 (CA)
Inventor: WOODRUFF KEITH FLOYD
IPC: B65D81/32
Filed: 1997-04-16
Abstract: A container for use in a closed application system includes a valve mounted to a discharge opening of the container and rotatable with the container for controlling the discharge of material from the container. The valve includes an element for engaging corresponding structure in a receptacle for receiving the contents of the container. The element engages and locks the valve in the receptacle when the valve is opened and the contents are being discharged from the container into the receptacle. The valve element and the corresponding structure on the receptacle cooperate so that the container can only be received in and removed from the receptacle when the valve is closed. In this manner, the contents in the container can be discharged only when the container is received within the receptacle and the container is rotated in a direction to open the valve.

Patent CA-2206619-A1 (CA)
Title: Feed forward amplifier system and method
Inventor: RICE CHRISTOPHER W
IPC: H03G3/30
Filed: 1997-05-30
Abstract: A dual loop feed forward amplifier and method of amplification. The dual loop feed forward amplifier contains at least two amplification stages thatintroduce unwanted intermodulation products into the output signal. A spreading tone is introduced to the RF signal in between the first and second amplification stages. The spreading tone is created by a bi-phase modulator that spreads an input tone in accordance with a spread PN- code. After the spreading tone is amplified by the subsequent stages of the feed forward amplifier, the spreading tone is despread by the same spread PN-code. The resulting output tone is mixed with the originalinput tone. The output of the mixer is then filtered to remove the unwanted spurious products produced by the mixer. The feed forward amplifier is then actively adjusted by a computer controller to reduce any difference between input tone and the output tone until a desired signal-to-interference ration is obtained.
Patent CA-2207295-A1 (CA)
Title: Timer camstack and clutch
Inventor: AMONETT DANIEL KEITH
IPC: H01H43/10
Filed: 1997-05-28
Abstract: An appliance timer has features to facilitate automated assembly or manual assembly. A timer housing base accepts timer components from two directions, and installation of components in either direction is along a straight axis. A motor in the timer engages a gear train which runs a drive cam. The drive cam imparts motion to a camstack which then engages timer blade switches, and the blade switches operate the appliance. A subinterval is also supplied on the timer to allow periodic operation of a switch without the use of the camstack. The timer also features a quiet manual advance which removes the blade switches from communication with the camstack to allow an operator to select various timer programs without any of the clicking noises that are usually associated with timer program selection. Furthermore, a detent slider is positioned in communication with the camstack to provide a tactile feel for the operator of the timer when selecting between various timer programs.

Patent CA-2218736-A1 (CA)
Inventor: HURWITT STEVEN D
IPC: H01J37/34
Filed: 1995-11-27
Abstract: A sputtering apparatus (10) is provided with a cathode assembly (21) formed of a cathode unit (22) having a moveable magnet assembly and a cooling water source therein, and a removable target assembly (23) that includes a replaceable target unit (25) and a removable and preferably reusable cooling jacket (40) that seals to the rear face (33) of the target unit and encloses a cooling cavity (45) therebetween. Ducts (50) are configured to automatically disconnect and reconnect the cooling cavity to the water source when the target assembly is removed from and reconnected in the cathode assembly. The target unit includes a volume of sputtering material on which is a front sputtering face (32), and has a recessed rim (34) surrounding the sputtering face. The rim is configured to form a vacuum seal to the wall of a sputtering chamber and a water seal to the cooling jacket. Thereby, the magnet assembly is isolated from contact with the cooling liquid. A central connection, preferably in the form of a projecting hub (35), is centered at the target unit back and connects to a shaft (65) in the cathode assembly to support the target material against distortion from pressure and heat variances, generally tending to force the center of the target into the processing chamber (13).  Preferably, the target (25) is formed of an integral piece of sputtering material, where the material permits, and otherwise the rim and hub may be part of a backing plate (25b) bonded to the target material to form the target unit. In either event, the back of the target unit is intrinsically, or is coated or otherwise treated to be, impermeable to contamination from the cooling water.

Filed: 1997-07-18
Abstract: Magnetofluorescent liposomes are size selected by membrane extrusion and magnetic separation. The selection process provides a highly fluorescent population of liposomes, which are used as a fluorescent labeling agent. Intensity of fluorescent staining can be increased 100-1000-fold without increased background fluorescence, when compared to conventional fluorochromeconjugated antibodies. The highly sensitive staining permits detection of cell surface markers expressed at low levels on the cell surface. Of particular interest is the detection of normally secreted certain cytokines, e.g. interferon .gamma., and IL-10 on the surface of lymphocytes. Cells that are positive for surface expression of these cytokines may be quantitated or separated for further use.
