Abstract: A game method and apparatus is disclosed. In the game, players use a game board, sets of response cards, board place markers, and a plurality of scenario cards containing brief situation descriptions and potential responses. Taking turns, players read a selected scenario card to another player. The latter player then decides which one of four possible responses best represents what he or she would truly do if faced with the described situation, and secretly indicates the choice with a response card. At the same time, all other players in the game predict how the player will respond by similarly choosing an appropriate response card. After players have all privately made their choices, they then reveal their responses. Accordingly, all players have an opportunity to then move their place markers around the board, depending on the responses given.
Abstract: A static article-rotating apparatus having a continuous helical channel designed within a tubular member is disclosed. One or more guides smoothly and continuously deflect an article as it passes through the channel thereby rotating the article.
Abstract: An apparatus for holding and tuning a thin film optical assembly is presented in which a housing receives a cylindrical thin film optical assembly which can be rotated to adjust the wavelength at which it passes or reflects an optical signal. The thin film optical assembly is composed of a thin film optical filter mounted on a cylindrical unit having a flat mounting face and an aperture for the transmission of light. The housing has a light path machined through it which permits light to pass to each thin film optical assembly, where one wavelength is separated by transmission and the remaining wavelengths are reflected to a subsequent filter. Each thin film optical assembly can be rotated within the housing to permit wavelength tuning. Once the thin film optical assembly is tuned it can be held in place using solder applied between the thin film optical assembly and the housing. Optical fibers are coupled to the housing using ferrules and graded rod index lenses.
Abstract: Handling equipment and a grapple device for handling balled plant loads such as trees and shrubs are disclosed. The grapple device which may be pivotally mounted on any suitable vehicle has a lengthwise frame. A pair of pivot rotary actuators having their rotational axes oriented transversely to each other are attached to the end of the frame. A grapple mechanism having pair of diametrically opposed grapple blades pivotally attached to a support member is fastened to one of the pivot rotary actuators. The grapple blades are opened or closed about the root ball of a plant by means of actuators, preferably hydraulic cylinder actuators. The grapple mechanism also has a slidably adjustable foot member which is positioned between the grapple blades to stabilize the plant load. The interior surfaces of the grapple blades and foot are adapted to engage the root ball of the plant.
Abstract: A wrist brace to prevent injury to persons such as concrete finishers who repetitively use their arms to support themselves or exert pressure against an object is disclosed. The wrist brace has a support element for maintaining the wearer's hand in a clenched fist configuration and a planar alignment of the hand, wrist and forearm. The support element is secured to the dorsal side of the wearer's arm by straps. The brace has a hand strap for securing the support element against the hand and maintaining the hand in a clenched fist during use of the brace. The support element also has cushioning such as foamed polyurethane adjacent to the wearer's arm. The support element may also have a hinge near the forearm to permit wrist and hand portions of the support element to be rotated thereby permitting the brace to be slidably retracted along the arm when the brace is not in use. This obviates the need to remove the brace entirely from the arm.
Abstract: An electronic digital plotter for navigators which relieves the rigors of mechanical manual plotting of position on a chart. The plotter utilizes either a flexible or rigid board employing electromagnetic or capacitive resistance technology. It makes use of a fixed X/Y coordinate system to generate latitude and longitude coordinates from a chart overlay. The plotter employs a pencil or pen type stylus with interchangeable cartridge to locate position, derived from electronic position information on the board and hence on the chart. By comparing the location of the stylus to the input data, the plotter directs the user to the input location utilizing a visual, bullseye director display. Given ship's position, on a dead reckoning track or expected destination or waypoint, the plotter gives course, speed distance, and transit time. The plotter can also accept inputs from hand bearing compass or ship's heading compass.

Abstract: Novel paint removing compositions, a method for their production, and methods for using the same, are described, which employ conventional active paint removing ingredients, in combination with auxiliary ingredients, which aid in lifting paint from a painted surface, such as an automobile body and which act to prevent re-adhesion of the paint, and to convert the paint-paint-removing composition mixture to a dry, friable mass, which is easily removed to exposed the bare substrate, and produce a dry, easily handled and disposable waste product.
Abstract: 3-(Hydroxyphenylphosphinyl)-propanoic acid is produced by reacting phenylphosphonous dichloride with a 0 to 20 percent molar excess of acrylic acid at a temperature of 60.degree. to 150.degree. C., heating the reaction mixture at a temperature of 115.degree. to 150.degree. for at least 45 minutes, and then hydrolyzing the mixture to obtain the desired product.
Abstract: A lithographic fountain solution concentrate is disclosed, the essential components of which comprises an aqueous mixture of:(a) from about 0.1 to 1.5 percent by weight of a water soluble film forming hydrophilic gum;(b) from about 0.75 to about 8.5 percent by weight of Polyvinyl Pyrrolidone;(c) from about 5.0 to about 30.0 percent by weight of a water soluble acid etchant;(d) from about 20.0 to about 50.0 percent by weight of a water soluble or water miscible glycol; and(e) from about 0.01 to about 1.25 percent by weight of a phosphate/phosphoric acid buffer system.The concentrate is adapted for further dilution by water to yield a fountain solution which when used in the printing process offers decreased scumming and blinding of printing plates while at the same time permitting a reduction in the amount of water applied to the plate. Improved print quality, reduced tendency to wet the paper, faster ink drying and improved ink/water balance is thereby achieved.

Abstract: C.I. Disperse Yellow 54 and 64 are important yellow dyestuffs of the quinophthalone type used in coloring synthetic fibers, particularly polyamide, polyester, acrylic and acetate fibers at boiling temperature conditions. Yellow azo dyestuffs of the hydroxypyridone type, e.g., C.I. Disperse Yellow 114, 180 227 and 230 have found widespread application in the high-temperature dyeing of such synthetic fibers. It has now been found that improved tinctorial results on these synthetic fiber materials can be obtained by applying a dyeing composition derived from these yellow coloring means and comprising a mixture of 70-90 parts by weight of one or more dyestuffs of the C.I. 54 and 64 type with 5 to 30 parts by weight of an azo dyestuff of the hydroxypyridone type. These improved dyestuff compositions exhibit superior leveling, high tinctorial strength or color build-up, high dyebath exhaustion and deep shade dyeing over the individual components.
