Abstract: A vacuum breaker for food processing equipment consisting of a tubular body having an interior defining a fluid flow passage.  The fluid flow passage has a first portion with a first axis and a second portion with a second axis.  A ball is disposed on a seat within the first portion of the fluid flow passage.  A push rod housing is secured to the tubular body in communication with the fluid flow passage.   The push rod housing is substantially in axial alignment with the first axis of the first portion of the fluid flow passage.  A push rod is disposed in the push rod housing and movable between an extended and retracted position.  An air cylinder is provided for moving the push rod from a retracted position to an extended position.  The push rod lifts the ball from the seat, thereby permitting the passage of fluids through fluid flow passage whereby the interior of the tubular body is cleaned in place.

Inventor: TROKHAN PAUL DENNIS
IPC: D21F7/08
Filed: 1991-04-08
Granted: 1999-06-15
Abstract: A process for improving the life of papermaking belts containing a cured photose nsitive polymeric resin is disclosed. The process includes the use of a resin-swelling solvent (e.g., isopropyl alcohol) t o deliver an effective amount of chemical compounds capable of slowing down the degradation rate of the photosensitive polymeric res in in the papermaking belt. The solvent delivery technique makes it possible to deliver useful quantities of chemical compounds t o the resin containing papermaking belts that would not normally be possible to add because of their low direct solubility in the polymeric resin and/or process incompatibility. Preferably, the chemical compounds are antioxidants (e.g., hindered phenols) whi ch inhibit or retard oxidation of the cured resin and its ensuing degradative effects.

Title: Graphical system for automated segmentation and recognition for image recognition systems
Inventor: BURGES CHRISTOPHER JOHN
IPC: G06V30/10
Filed: 1992-11-24
Granted: 1999-01-12
Abstract: Apparatus and processes are described for the automatic recognition of alphanumeric images. A set of cuts are made to the image which include incorrectsegmentations. The resulting "cells" comprising in their totality the created segments of the image are then analyzed to determine which cells are legal neighbors and which are not. All cells which are legal neighbors are then presented as connected nodes. A pruning of nodes which are related to certain predetermined image cuts is effected. Each set of remaining connected nodes is then presented to a recognizer which identifies the image and assigns a specified probability to theoutput. Many cells which are not legal neighbors are thereby not presented to the recognizer, thus saving substantially on computations per recognized image.

Title: Feed forward amplifier network with frequency swept pilot tone
Inventor: TATTERSALL DEREK L JR
IPC: H03F1/32
Filed: 1992-03-17
Granted: 1996-05-28
Abstract: Briefly described the present invention is a feed forward amplifier network (200) employing a frequency swept pilot tone signal in order to reduce the distortion generated by the network's power amplifier (202).  A frequency swept pilot tone, generated for example by a variable frequency oscillator (213), is injected into the input path of the power amplifier's (202) input signal. Thereafter, distortion cancellation is employed to generate an amplifier output signal, substantially free of both pilot tone and the distortion signals generated by the power amplifier (202).  The amplified output signal is then detected by a detector (215) which is phase locked to the variable frequency oscillator (213) in order to ascertain the average pilot tone energy remaining within the am-plified output signal.  In response to a detection, various amplifier network characteristics are adjusted in order to reduce the amount of pilot tone at the amplifier network output (217).

Title: Method of evaluation of a set of linguistic rules
IPC: G06F7/60
Filed: 1993-11-12
Granted: 1999-03-09
Abstract: The present invention provides a method for generating an output for a fuzzy controller by evaluating a set of linguistic rules prepared according to a method included in the invention.  According to the present invention, for each input signal the linguistic hedge is formed to be a fuzzy information system; each linguistic rule is formed with a premise consisting of a multitude of linguistic statements about pairwise different input signals, linked by AND, or consisting of one statement about one input signal, and a conclusion consisting of a linguistic statement about the output signal of the fuzzy controller; the set of rules is built such that it forms as a complete and consistent set of linguistic rules.  Then, for every linguistic rule the membership function associated with the linguistic statement about the output signal in the conclusion of the rule is defuzzified to produce a first signal for each rule.  For every linguistic rule, second signals are produced, one second signal for each linguistic statement in the premise of the rule, by determining the degree of membership of the current value of the input signal referred to in the linguistic statement to the fuzzy set characterized by the membership function associated with the linguistic statement.  For each linguistic rule, the second signals are multiplied to produce a third signal for the rule.  For each of the linguistic rules, the first and third signals are multiplied to produce a fourth signal representing the weighted recommended action corresponding to the rule.  Finally, the fourth signals of all the rules in the set of linguistic rules are added to produce the output signal.

Abstract: A head cooling device for mounting over a person's head, generally within a headgear or a safety helmet. The device comprises: a housing, defining a main body enclosing a generally closed pocket, for containing ice cubes therein, a mouth, at one end of the main body, and an intermediate flooring, for supporting the ice cubes inside the pocket spacedly from the mouth. Thus, the flooring remains spaced at all times from the scalp by a spacing gap. The flooring is bored at its periphery, for enabling water droplets from the melting ice cubes to escape one at a time from the pocket, freely through the spacing gap and toward and against the person's head scalp. Flexible bands are used, integral to the housing, for releasably anchoring the housing to the head in generally overhanging fashion.
