Title: Multiple zone audio system
Inventor: PAYNTING RICHARD J
IPC: H04B1/20
Filed: 1990-08-16
Abstract: MULTIPLE ZONE AUDIO SYSTEM             Abstract of the Disclosure An audio system may be monitored and controlled from one of many remote locations.  The audio sources are located at a central location, however, the signals monitored at a remote location may originate from the same or a different source as the signal being monitored at the central location or any other location.  The sources are selected and routed to speakers by at least two independent selectors, and the volume is controlled by associated volume controllers, either in the speakers or at the central location.  Control of the system is simplified through the use of one or more radio frequency remote controls.  Commands issued to the system from a remote control are verified by a verification signal added to the output signal on the appropriate output channels.  To alleviate confusion, remote controls retain exclusive control over the source and output they most recently controlled.  General function keys on the remote controls are used to control specific functions of the currently selected source, but may map to functions in more than one source.

IPC: H04N7/18
Filed: 1990-09-26
Abstract: A camera (18) arranged in the axis of a bottle to be tested is used to take pictures in order to determine defects in the upper end face of the mouth lip (43). A circular, coaxial light-conducting body (30) which is surrounded by a light source (28) is arranged between the lip (43) and the camera (18). It has a central viewing opening (40) with the shape of a double conical frustum (40a, 40b). The cylindrical surface of the conical frustum (40a) facing the lip forms a light exit surface (46a) for illuminating the lip (43). The angle of slope of the conical frustum (40a) is selected such that an annular optical conical frustum (52) falls onto the upper end face of the lip (43) and has in the middle thereof an angle of incidence of approximately 45 DEG . This yields a dark field illumination of the lip (43). Should a defect be present in the region of the upper end face of the lip (43), it becomes visible brightly on the dark background. Lateral defects of the lip (43) can also be determined with the aid of an additional light-conducting body (34).

Patent CA-2030221-A1 (CA)
Inventor: PELLERITE MARK J
IPC: C09J7/02
Filed: 1990-11-19
Abstract: ABSTRACT OF THE DISCLOSURE            This invention relates to release liners, and more particularly, to release liners suitable for use with highly aggressive pressure-sensitive adhesives.  Certain pressure-sensitive adhesives, particularly those derived from silicone resins, are so aggressive that tapes employing them exhibit undesirably high peel forces upon removal from known low-adhesion coatings, especially after prolonged storage or when used in a high-temperature environment.  The adhesive of such tapes may carry away, and consequently, be contaminated by appreciable amounts of the low-adhesion material.  If this occurs, the tapes will exhibit poor readhesion when applied to "end-use" receptor surfaces.  This invention provides curable, crosslinkable compositions and coatings prepared therefrom that can be used to form low-surface energy liners that can be used with aggressive pressure-sensitive adhesives, such as adhesives formed from silicone resins.  The release characteristics of these coatings do not diminish upon aging and do not adversely affect the readhesion properties of adhesives that have come in contact with the coatings.  The invention further provides substrates bearing a layer of the composition of the invention. These coated substrates are particularly suitable for release liners, especially differential release liners and low-adhesion backsizes for pressure-sensitive adhesive tapes and sheet materials, especially for pressure-sensitive adhesives derived from silicone resins. Because the coatings of this invention can have more than 50% by weight inert oils without significantly reducing the readhesion of adhesives removed from them, they provide an economic advantage over those coatings prepared by using only the more expensive reactive group-containing polyfluoropolyethers.

Title: Process for the treatment of hot waste gas containing hydrogen chloride
Inventor: MAK KAI K
IPC: B01D53/68
Filed: 1990-11-19
Abstract: PROCESS FOR THE TREATMENT OF HOT WASTE GAS        CONTAINING HYDROGEN CHLORIDE ABSTRACT OF THE DISCLOSURE           The specification discloses a process for the treatment of waste gas containing hydrogen chloride wherein the gas is at an elevated temperature in the range of from about 300°F to about 3000°F and is produced from the thermal decomposition of material contaminated with hazardous chlo-rinated organic compounds.  The waste gas is contacted in a reaction unit with an alkaline brine solution under condi-tions such that hydrogen chloride in the waste gas reacts with the alkali to form a chloride salt and water.  The heat of the gas evaporates water from the solution to maintain the salt concentration sufficiently high to cause the forma-tion of salt crystals in the solution.  The gas is conducted from the reaction unit following contact with the solution under conditions such that the gas includes water evaporated from the solution.  The salt crystals are removed as a solid product of the process and water and alkali are added to compensate for water vaporized from the solution and alkali consumed in the reaction.  The process requires no external heat input and there is no liquid discharge.
Patent CA-2031021-A1 (CA)
Title: Shuttle shift transmissions
Inventor: BULGRIEN GARTH H
IPC: F16H59/00
Filed: 1990-11-28
Abstract: A microprocessor controlling a shuttle shift transmission may be programmed while the gearshift lever is in neutral to preselect a forward and reverse gear into which the transmission is shifted when the gearshift lever is moved to a forward or reverse position. The microprocessor may also be programmed so that, in shifting between forward and reverse, the forward and reverse gears selected differ by a pre-programmed amount. The microprocessor may be programmed to control vehicle deceleration by selecting gears in the transmission so that the transmission and/or the vehicle engine become a load for decelerating the vehicle. In a diagnostic mode, the microprocessor executes a routine to develop a clutch calibration value which may later be used to insure uniformity of clutch operation in different vehicles, or in the same vehicle over a period of time. The normal speed ratio matching which normally takes place when shifting gears may be manually overridden by operator manipulation of the gearshift lever. The override may either terminate speed ratio matching for a particular shift, or the override may be effective for a fixed interval of time.

Abstract: Application  of  substantial  pressure to ends of a frankfurter. concurrent with passing of electrical current, through the  application of  a cooking tray whose structure accepts multiple frankfurters and allows the pressure to be applied  by  the  use  of  a  carriage system with multiple plungers whose  points  of  contacts  serve  as electrodes; use of aluminum foil patches between the extremities of the frankfurter and electrode plunger cups is  made to maintain conductivity  with  said  aluminum patches being applied by use of a paper tape sprocket system which is microprocessor controlled  or   in  the  alternative  by  manual  operator insertion in a modified  cooking tray  which eliminates the need  of  the  paper  tape sprocket system.  Application of pressure to  extremities  of  the  frankfurter  is  well in excess of that required for mere electrical contact, but is part of  the  cooking  process  for  producing  a processed frankfurter in  less than  40 seconds with high reliability by passing an electric  current without  burning or arcing.          Within the frankfurter, the substantial pressure eliminates voids and  provides a  consistent electrical  contact.  The apparatus  allows   for  the   use  of  various  brands  of frankfurters in as much as a  consistent uniform electrical contact  is  provided  by  the  use of a combined specially shaped plunger which also serves as part of the electrode.

Title: Rf filter alignment using digital processor clock
Inventor: LAI JUNE-SAN
IPC: H03J7/06
Filed: 1991-07-29
Abstract: Abstract of the Disclosure A variable frequency RF passband filter is calibrated to maximize the sensitivity of a radio receiver using reference frequencies applied based on the clock operation of a digital processor within the receiver.  The reference frequency passing through the variable passband filter is mixed to the intermediate frequency of the receiver and its level is detected.  A frequency counter verifies that a measureable reference frequency signal has in fact been mixed to the intermediate frequency in order to avoid errors.  The correct control voltage signal for the variable passband filter corresponding to each receiver frequency can thus be conveniently and inexpensively determined and stored for use during normal operation of the receiver.
