Patent CA-2156029-C (CA)
Inventor: SMILEY JOHN OMAR
IPC: G02B6/35
Filed: 1995-08-14
Granted: 2000-02-29
Abstract: An optical switch has a stepping motor with a fiber faceplate on which are mounted end portions of output optical fibers terminating in GRIN lenses. The end portions are arranged along a pitch circle. The faceplate is spaced from the stepping motor and the diameter of the pitch circle is smaller than the diameter of the stepping motor, the output fibers diverging from the faceplate towards the motor and beyond in a space-saving arrangement. The stepping motor drives a movable arm with attached end portion of an input optical fiber, also with a GRIN lens, into one of a plurality switching positions. The connection between the fibers and the lenses and also the relative axial arrangement of the paired lenses in the switching positions is offset to reduce or minimize the reflection of light transmitted from the input fiber to the output fiber, back to the input fiber.

Title: Beverage dispensing control
Inventor: BETHUY TIMOTHY W
IPC: B67D1/14
Filed: 1995-11-10
Granted: 2006-07-11
Abstract: An electronic control for an automatic filling beverage dispensing valve is shown. The dispensing valve includes a valve body, a flow control mechanism and a solenoid. The valve further includes an electrically conductive cup actuated lever for operating a micro-switch that is operatively connected to the electronic control of the present invention. The valve body includes a nozzle and a stainless steel electrical contact for providing electrical connection between the electronic control and the beverage as it flows through the nozzle into a cup. The electronic control the present invention is microprocessor controlled and includes an internal signal generator which generates a signal independent of the input line frequency supplying the power to the control. This generated signal is buffered and applied to the dispensing cup lever while simultaneously being applied to a reference input of a phase-locked loop detector circuit. When beverage fills a cup to the rim thereof the beverage can flow over the rim and thereby provide an electrical continuity between the electrically conductive lever and the stainless steel contact within the nozzle. Thus, a signal is conducted to an input of the phase locked-loop detector circuit where that electrical signal is compared to the generated reference signal. If the two signals are matched in both frequency and phase, the detector circuit generates a continuity detected signal to the micro-processor. The microprocessor thereby ends dispensing by de-energizing the solenoid.

Title: Process for the application of dye fixing agents to polyamide fiber utilizing controlled fixing agent addition
Inventor: HOLFELD WINFRIED THOMAS
IPC: D06P1/39
Filed: 1994-05-20
Granted: 2004-03-02
Abstract: A process for increasing the washfastness of a fibrous article containing polyamide fibers dyed with anionic dye by treatment with an anionic dye fixing agent. The process includes immersing the article in a liquid bath of either an aqueous or substantially nonaqueous solvent medium for the fixing agent and heating to a temperature at least equal to the dyeing transition temperature of the fiber. The fixing agent is added to the bath so that the rate of fixing agent addition to the bath is the primary control over the rate of fixing uptake by the article at the early stages of aftertreating. In the later stages, the rate of fixing agent addition controls the concentration in the bath whereby the propensity for the fixing agent to agglommerate from the bath is decreased.

Abstract: A composition of matter includes a polymerizable mixture comprising 1 to 99 weight percent of a first monomer and an initiator therefor, the first monomer being one of 1) at least one free-radically polymerizable monomer or 2) at least one cyanate ester monomer, and 99 to 1 weight percent of a second monomer and an initiator therefor, the second monomer being the member of 1) or 2) that is not selected as the first monomer, wherein the curative for the cyanate ester is a transition metal-containing organometallic compound curing agent and the curative for the free-radically polymerizable monomer is a free-radical generating curing agent or a transition metal-containing organometallic compound. The polymeric mixtures are useful, for example, in applications requiring high performance, such as high temperature performance; in composites, particularly structural composites; structural adhesives; vibration damping materials; electronic applications such as printed wiring boards, semiconductor encapsulants and electronic adhesives; photoresists; injection molding and prepregs; protective coatings; tough self-supporting films; and high performance binders. In addition, a curable composition comprising two partially polymerized mixed syrups of ethylenically unsaturated monomers is provided. These compositions are useful as the precursors for vibration damping materials. Further, a curable composition including (1) an ethylenically unsaturated monomer or (2) an ethylenically unsaturated monomer and a cyanate ester monomer, and certain organometallic neutral compounds is useful in the graphic arts.

Abstract: The present invention provides a method for producing a desired protein. The method comprises growing, by a fed-batch culture, a host cell which expresses the desired protein, wherein the specific growth rate of the host cell is changed from the initial rate to a predetermined one by continuously changing the rate of addition of a substrate which controls the growth of the host cell. According to the mode of change of the rate of substrate addition to the medium of the present invention, optimal patterns of specific growth rate µ and specific production rate .rho. can be realized to optimize the fed-batch culture system. As a consequence of the realization, it is possible to perform a high density culture of the host cell by fed-batch culture, and the desired protein can be produced efficiently in a short time.

Abstract: A communication package has, enclosed in a storage disc, a voice chip connected by power input bus terminals to a renewable, battery power system which provides easy battery accessibility. The storage disc preferably contains an acoustically resonant chamber and diffusion apparatus and preferably contains a removable barrier between the power system and the power input bus terminals that must be removed before the voice chip can be energized (Figure 3). A voice message is stored in the communication package by recording the voice message into a recording unit, replaying the voice message, optionally re-recording at least a portion of the message until the replay is satisfactory, converting the message to a compressed, digital "sound file" and then downloading this "sound file" onto the voice disc. Identifying information is converted into a compressed, digital "text file" and transmitted with the "sound file" to be displayed as a visual identification of the "sound file" (Figure 4).
