Abstract: A method of producing a choline having a high purity without containing by-products by using a molecule-inclusion complex of the choline as a starting material. A choline inclusion complex without containing by-products is obtained by reacting an aqueous solution of the choline containing, as by-products, those cholines to which are added ethylene oxides with host molecules such as of 1,1'-bis-.beta.-naphthol, and is further reacted with a carbon dioxide gas in order to obtain an aqueous solution of a choline carbonate and/or a choline bicarbonate of a high purity, which is then subjected to the electrolysis using a cation-exchange membrane as a diaphragm, in order to obtain an aqueous solution of the choline of a high purity without containing by-products. The choline that is obtained is a strongly basic compound having a high purity and is very useful as a photoresist-developing solution.

Abstract: Organoselenones of the formulaR.sub.1 --Se(O.sub.2)--(CH.sub.2).sub.n --Xwherein R.sub.1 is selected from the group consisting of aryl, vinyl, acetylenyl, and aralkyl, n is an integer equal to 2 to 6 and X is a leaving group selected from the group consisting of halides, sulfonates and selenones; were surprisingly found to be useful as alkylating agents which possessed a high degree of selectivity for nitrogen nucleophiles without the usual increased preference for sulfur nucleophiles. This property allows the effective use of these compounds as anti-cancer alkylating agents suitable for use in drug-resistant cell lines which display either thiol mediated drug resistance or MER(+)-mediated drug resistance. Two methods of synthesizing these compounds are also provided.

Abstract: A game is played by building a tower of bricks in multiple levels, and players alternately removing a brick from one level and adding it to the top of the tower to build new levels, until collapse of the tower occurs. Bricks of a variety of different types are provided with each type having different physical characteristics, such as shape, size, surface configuration and/or coefficient of friction. At least two adjacent layers of the initial tower are formed from bricks of different types.

The heat-resistant epoxy resin composition having excellent stability at room temperature comprises an epoxy compound having two or more epoxy groups, a curing agent which comprises a naphthalenedicarboxylic dihydrazide as a main component, and a ceramic whisker as a filler.

Abstract: A portable heat exchange unit for cooling a medium including a vessel adapted to contain a discrete quantity of a compressed or liquefied gas wherein the vessel includes a wall arranged to be placed in contact with the medium to be cooled, a valve for operatively controlling the release of the gas from the vessel, a panel positioned adjacent and inside the wall of the vessel for operatively directing the gas into heat exchange contact with the wall of the vessel and arranged to release gas from the top of the panel, and a means for exhausting the gas from the vessel. The panel has ridges thereon and engages the wall so as to form a plurality of channels between the ridges and the wall.

Abstract: A drinking mug which includes a central core for holding liquid and having an outer surface. A hollow sleeve of flexible molded plastic material is disposed over the central core. The central core defines an outwardly protruding key while the inner surface of said hollow sleeve defines a keyway. The key and keyway are engaged in mating relationship to hold the sleeve non-rotationally upon the outer surface of the core.

Abstract: A torchiere lamp having a base and an upwardly directed general area lighting fixture supported upon a stem extending from the base. A task light is supported upon a rod which passes through a pair of anchors secured to the stem so that the rod is disposed substantially parallel to the stem. One of the anchors carries a locking member in the form of a threaded thumb screw which may be loosened to permit vertical and rotational movement of the rod for positional adjustment of the task light. The task light includes a reflector or shade pivotally attached to the rod to thereby permit further rotational and pivotal adjustment of the reflector.

Abstract: An integrated compliance electrohydraulic servovalve system connected to a load such as a simulated living being to provide more realistic movement thereto. The system includes a pressure transducer for sensing the pressure appearing at the output of the electrohydraulic servovalve and which is applied to an actuator connected to the load. The pressure as sensed is developed into a corresponding electrical signal which is used as a feed back signal to the drive motor of the electrohydraulic servovalve. The actuator position signal is also provided and is summed with the position command input signal to provide the command signal which is also summed with the pressure signal prior to application to the drive motor. The utilization of the pressure feed back signal provides compliance to the over all system resulting in a realistic movement of the simulated living being.

A metal sleeve having a spool valve slidably disposed therein is placed within opposed cavities formed within opposite housing halves. The housing halves are brought together under pressure and an ultrasonic horn is activated. Energy directing beads formed on the housing halves as well as interfering surfaces about the periphery melt under a pressure and ultrasonic energy allowing the two housing halves to move toward each other and mate. Upon deactivation of the ultrasonic horn, the molten plastic material cools and forms a seal about flow ports in the metallic sleeve as well as a fusion bond about the periphery of the housing.
