Title: Method and apparatus for steering casting belts of continuous metal-casting machines
Inventor: DESAUTELS JERRY S
IPC: B22D11/16
Filed: 1990-05-01
Abstract: A method and system achieving increased steering precision of flexible, metallic endless belts of continuous metal-casting machines. Such belts often have imperfections for example, low-carbon steel belts, generally have a "camber" curvature of their edges in their plane. Belts revolving in the machine normally are steered through sensing side-to-side position of one edge. The edge passes a sensor during every revolution of the belt. If the edge has camber, a prior art steering system continually will "hunt" in response to variations in side-to-side position of the cambered edge. This hunting causes repeated side-to-side belt motions, thereby inducing wear of belt coatings under edge dams, causing non-uniform heat transfer. Hunting also induces diagonal stresses and flutes in casting belts adversely affecting casting. The present sensor circuit following the "Cue" governs steering, thus eliminating or substantially reducing prior-art "hunting" steering problems.

Abstract: ABSTRACT    A joining device for end joining at least two members of a frame is provided.  Each frame member has a front surface, a bevelled joining surface on an end of the frame member and a cavity of trapezoidal cross-section extending along a portion of the longitudinal axis of the frame member.          The broadest portion of the trapezoid is located closest to the front surface of each frame member.  The cavity is exposed at the bevelled joining surface.  The joining device includes at least two insertion portions of trapezoidal cross-section which are oriented with respect to each other according to a first angle which determines the angle between the frame member, whereby the bevelled joining surfaces of the frame members become contiguous when the insertion portions of the joining device have been inserted longitudinally into the frame members.
Patent CA-2019078-A1 (CA)
Inventor: HATAKEYAMA IZUMI
IPC: H03M13/41
Filed: 1990-06-15
Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to a Viterbi decoder for decoding a convolution coded reception signal. The Viterbi decoding is an algorithm for efficiently executing the maximum likelihood decoding using a convolution code by selecting a path locating at the minimum distance from a reception series between two paths which are joined.  Since it is necessary to store a state metric of each state, after the state metric of the surviving path was calculated by ACS calculation, it is considered to normalize metrics. However, this results in a large circuit scale and a low processing speed.  Therefore, in this invention, a maximum likelihood value of a present state metric is detected from a maximum likelihood branch metric pair before the ACS calculation and the preceding maximum likelihood state metric pair and metrics are normalized by using the maximum likelihood value.

Title: Method and apparatus for beverage blending and proportioning
Inventor: GIBNEY MICHAEL W
IPC: A23L2/00
Filed: 1991-02-19
Abstract: The present invention relates to a method and apparatus for improving quality and increasing syrup yield within a typical beverage proportioning system (50). The invention controls the proportional blending as a function of the mass flow of the components input to the propor-tioner (50). The mass flow determination is made by Coriolis-type mass flow meters (54, 60) positioned within the feed lines (52, 58) for the water and syrup, respec-tively. From this mass flow determination an adjusted volumetric flow value for each component is determined by a master controller (68). The ratio of the calculated volumetric flow of the water to the syrup is used to determine a signal to control the proportional blending.      The controller (68) sends a signal to an actuator (70) which adjusts a valve (72) for the water flow into the blending portion of the proportioner (50). The controller (68) also determines the accuracy of the adjustment and the efficiency of the overall blending and proportioning system.

Abstract: PROCESS FOR AUTOMATICALLY DETECTING AND LOCATING A          TARGET FROM A PLURALITY OF TWO DIMENSIONAL IMAGES     Abstract of the Invention:    A novel data processing technique is provided for detecting  and locating a target from a plurality of two-dimensional images generated by an imaging sensor such as an imaging lidar system.  The present invention processes this series of two dimensional images (made with one or more imaging detectors) in an optimal statistical fashion to reliably detect and locate targets.  This invention is a process by which the images are mathematically modified to reduce the deleterious effects of noise and thereby provide the highest possible probability of detection while simultaneously maintaining a very low probability of false alarm.  The data processing technique described herein also provides an estimate of the reliability of the detection, the target location and an output image to be displayed for visual confirmation and perhaps classification by the operator.  The method of the present invention includes some or all of the following steps: noise reduction, spatial filtering, noise parameter extraction, asymmetric threshold detection, contrast stretching, localization, recognition, range or depth determination and subimage mosaic generation. The present invention is particularly well suited for processing two dimensional images of underwater targets generated by an imaging sensor located on an airborne platform whereby the underwater target is precisely and accurately detected, located and identified.

Abstract: A fluorescent lamp utilized in a document scanning system is environmentally and thermally stabilized by means of a bifurcated heater control assembly. A heater blanket is wrapped around the entire surface of the lamp including the end areas surrounding the filaments but exclusive of the aperture through which light is emitted. The size and temperature of the lamp cold spot are selected emperically to maximize output power and minimize illumination transients during power on. The heater jacket has thermostat control set points which, in both the lamp standby and energized states, maintain the blanket and lamp assembly at a constant elevated temperature which is above that achieved by lamp heat alone. Since the temperature distribution is always determined by the blanket and never by the lamp, changes in temperature or temperature distribution (and hence illumination distribution) as the lamp transitions from standby to full on are minimized.
