Abstract: A water temperature sensing/flow control mixing valve has a valve body with hot and cold water inlets and at least one outlet. A mixing valve member is positioned within the valve body and controls the proportion of hot and cold water that flows from the outlet. A water flow restrictor is positioned within the valve body and movable from a normal flow position in which outlet flow is unobstructed to a position in which the restrictor partially closes the outlet to limit flow therefrom. There is a shaped memory metal actuator positioned within the valve body to move the restrictor from the normal flow position to the flow limiting position when the water within the valve body exceeds a predetermined temperature.

Abstract: A cutting tool such as a body drill has a cylindrical shank portion and a body section connected to the shank portion. The twist section terminates at a cutting end. A pair of flutes are formed in the body section, defining a land therebetween. The land includes a narrow margin having a width between 0.015 and 0.025 inches. The land also has a body clearance of a diameter less than that of the margins. The flutes terminate at flute faces at the cutting end. The flute faces are disposed parallel to each other at a zero degree rake angle. The narrow margin aspect of the invention could also be applied to a counterbore or spotface.

Abstract: A tabletop bowling game including a small scale replica of a bowling alley. A platform is mounted above the replica of the bowling alley at one end thereof. Ten upstanding posts are formed on the platform with the posts arranged in seven columns extending lengthwise of the bowling alley to provide a pattern of posts similar to the pattern of pins on a bowling alley. Each post receives and supports a small scale replica of a bowling pin. Each small scale replica of a bowling pin has a spring which is compressed by its post and which biases the bowling pin in a direction upwardly off the post. A releasable hook mechanism is provided for holding each bowling pin replica on its post against the bias of the spring. Targets extend downwardly from the platform and terminate slightly above the bowling alley with each target aligned with a single column of posts. Slides connect the targets and the hooks to release one of the hooks from its bowling pin replica upon movement of the target.

Abstract: A positioner for accurately and precisely positioning an optical member such as a lens aligned with the tip of an optical fiber in relation to an optical device such as a beam launcher/splitter; the positioner includes a tilt base mounted in a frame and angularly displaceable about orthagonal X and Y axes defined by three ball bearings all engaging one surface of the tilt base and all biased against the tilt base. Two differential screws mounted on the frame engage two of the ball bearings to effect angular yaw and pitch adjustments. The tilt base is connected to a retainer support in turn connected to a retainer member; two additional differential screws engage the support through further ball bearings to effect linear movements of the retainer member along the X and Y axes.

Abstract: A jack for railroad well cars has a frame comprising a central section which fits between the rails and the underside of the car frame. The central section spans the rails and extends somewhat beyond the sides of the car frame. The central frame section connects to a fixed, upright frame section at one end and a pivot section at the other end. The pivot section is movable between a horizontal setup position and a vertical operating position. A lifting beam is mounted on the frame and extends transversely to the car frame. Hydraulic actuators connected between the ends of the lifting beam and the frame are adapted to move the lifting beam between lowered and raised positions. A ratchet and pawl are provided on the upright and pivot frame sections to prevent unwanted lowering of the lifting beam.

Abstract: Analyzing the level of a treating agent and/or stress metals in a body of water containing an inert transition metal tracer added to the water proportionally with the treating agent by determining the absorbance (first absorbance value) of a reagent dye added to water, said dye producing a second absorbance value when reacted at the same concentration with the tracer and stress metals in a measure of said body of water, and said dye producing a third absorbance value when reacted at the same concentration with only the transition metal contained in a measure of said body of water; determining the second and third absorbance values and resolving their differences to determine the concentration of the tracer and, separately, the concentration of said stress metals.

Abstract: A system and method for reclaiming unused portions of mixed concrete by adding a chemical agent to retard the hydration state of the concrete for up to several days. When the stored concrete is again desired for use, a chemical accelerating agent is added to the mixed concrete which returns the hydration state to normal, once again allowing the concrete to set. The concrete can then be poured at a construction site or alternatively, the stored concrete can be added to a new batch of newly mixed concrete before pouring.

Abstract: A flexible bar code printing plate formed with an ink density gauge rib for concurrently printing a tint gauge whereby the code and tint gauge are printed concurrently enabling the printed gauge to be inspected for a tint pattern deemed indicative of a well-printed bar code image.

The rinse wheel is disposed in a tub which contains a plurality of nozzles for spraying rinse solution on the ends carried by the rinse wheel.

Abstract: A microprocessor based decoder module for television video signals which have been encoded by suppressing sync pulses and/or inverting picture video. The decoder modules generates sync restoration gates and/or video inversion gates developed from timing signals present in the VBI of the encoded video signal. The VBI timing signals may be either sync pulses which are not suppressed during the VBI, or special timing signals inserted at the video encoder. The microprocessor, in the decoder module, may contain externally selectable program segments where each segment will allow decoding of a different variety of video encoding.

Abstract: The present invention relates to a dynamic weight control system for a slicing machine, used to slice bacon or other food products, that has both primary and secondary weighing systems. The slicing machine has a slicing blade and a feed mechanism for feeding a food product (e.g., a bacon slab) into the slicing blade at a controlled rate. The primary weighing system controls primary slicing and weighing of multi-slice drafts of the sliced products so that each draft is an approximation of a prescribed control weight. The secondary weighing system checks draft weights and supplies data to a computer that computes an average weight for those drafts that are within an acceptable weight range; it also computes the pass ratio of acceptable weight drafts for a sample group of drafts.

Abstract: Method of restricting a coating to a first area having an adjacent second area which is to be covered by a mask before the coating is applied, including the steps of separating the areas with a barrier strip of masking paper, applying a masking composition to the second area pressing the paper against the composition to produce a guarding edge between the first and second areas, and applying coating material to the first area, the masking composition inhibiting dust on the second area from marring the coating, and protecting the second area from coating overspray. Also disclosed is a masking system including the barrier strip of masking paper pressed against the film of the masking composition applied to the painted portion of an automobile. The masking composition is easily removable by a water wash after coating of the unmasked area of the automobile.

Abstract: This is an improvement for a powered floor scrubber which in use is moved forward and backward across a floor to be scrubbed. A scrub brush is rotated within a housing which is open at the bottom and water is supplied within the housing. The improvement consists of attaching double lipped suction squeegees at both the front and rear of the housing and connecting them both to a source of vacuum to suck up soiled water from the floor. The flexible squeegee lips are mounted in such a way that as the machine is moved forward the lips of the front squeegee fold together and shut off the airflow to it while the rear squeegee remains functional. When the machine is moved backward a reverse action of the squeegees occurs, so that there is always a functional squeegee sucking up soiled water behind the scrub brush while airflow to the opposite squeegee is shut off whether the machine is moving forward or backward.

Abstract: A box-like frame member is formed by compressing an internally-pressurized tubular blank within a die having a cavity conforming to the final box-like cross section desired for the product, and increasing the pressure to exceed the yield limit of the wall of the blank to expand the blank into conformity with the die cavity. The blank is selected so that the final product and the die cavity have a circumference preferably no more than about 5% larger than the circumference of the blank, to avoid weakening or cracking of the blank through excessive circumferential expansion. The internal pressure forces the blank evenly into the corners of the die on closing and allows the blank to be confined within the die without sections of the die pinching the blank on closing of the die.
