Abstract: An automatic closure for collapsible tubes, squeeze bottles, and the like containers of the type formed from resilient plastic material. The container typically is tubelike, provided with a tapered or frusto-conical neck portion terminating in a flattened mouth defining end lips forming an openable closure. Pressure applied to the body of the container remote from the lips to forms a transverse pinch-off across the end portions wherein the lips are deflected or bent along a line of curvature to one side or the other and at an angle to the axis of the container, and wherein the lips are also bowed, having a curved contour. Such pinch-off forms a closure across the neck portion. The pinch-off opens in response to pressure on the walls of the container proximate thereto in a manner to relive the pinch-off and permit the fluid contents to flow. Specifically, the pinch-off is in the following form: the end lips of the neck have a bowed contour about the lengthwise dimension.

Abstract: Malonic anhydride and substituted malonic anhydrides are prepared by ozonolysis of the enol-lactone dimers of ketenes. The resulting malonic anhydrides can be hydrolyzed with water to form the corresponding acid, reacted with an alcohol to yield the monoester, or reacted with an amine to yield the monoamide.

Abstract: A secured scramble decoder filter comprised of a narrow band filter assembled on a fragile substrate and mounted in a housing wich automatically destroys the filter when any tampering is attempted. The filter is a series tuned network bridging a conductor coupled through a capacitor to a parallel tuned network, which is connected to ground. The coils for the filter are printed on a special electronic glass tube for temperature stability while the capacitors are deposited on the fragile substrate. The filter is mounted in a sealed housing in brackets with a spring, loaded to break the substrate when the device is tampered with to render it inoperative. The device is provided with a mounting screw requiring a special tool for removal so that when the device is mounted any prying in an attempt to remove the device will trigger the destruction of the filter.

Abstract: A clear plastic pillbox having an intermediate longitudinal channel and lateral partitions which form a multiplicity of compartments therein for storage and convenient dispensing of medicament tablets. The pillbox is sealed by a clear plastic cover having a plurality of slots through its surface which form peripheral seals around the projections of the lateral partitions above the sidewalls of the pillbox and thus individual sealing tabs are provided for each of the compartments created by the longitudinal channel and lateral partitions. The individual sealing tabs are frangible and may be broken away to provide access to particular compartments, which may be pre-loaded by pharmacists with medicament tablets or doses of medication for scheduled use.

Abstract: A one-piece container formed as an injection molding preferably from polypropylene. The single piece is molded in preformed sections joined by thinner portions or parts of material which serve as hinges, the sections being relatively moveable about these parts. The sections are preformed to constitute portions of a container along with a closure for the container so that when the sections are moved about joint parts a complete container with a closure cover is formed. Preferably the container has inwardly extending flexible members formed on at least one section to engage an article within the container to retain it in position. The container is particularly adapted for use with calculators.

Abstract: A readily removable tool holder constructed to be held in a receptacle which may be carried on the spindle of a tapping attachment. A torque release clutch is built into the removable tool holder for the purpose that when one tool holder is substituted for another, it is not necessary to make adjustments in the torque release clutch of the tapping attachment itself. The parts of the torque release clutch are of relatively small diameter to fit into the tool holder. Improvements are embodied in the torque release clutch. Clutch members are provided including a first clutch member and a second clutch member. The main biasing spring acts on the first clutch member. When the clutch parts are disengaged, the first member is moved against the spring and held in an inactive position wherein it is completely out of engagement with the teeth of the other clutch member to eliminate wear.

Abstract: Portable hydraulic tube bending machine adjustable for bend angle and adjustable to tubing with and without collars and straight and pre-bent tubes, whereby complicated bendings can be carried out at the place of use and with a minimum of space.

Abstract: A grasping device having an elongated stem with manual operating means at one end. At the opposite end are a pair of jaws actuatable by a rod telescoped within the elongated stem. The manual operating means includes a lever that is manually grasped to be pulled towards a fixed handle, the operating lever having connections to a line which has engagement with the actuating rod for moving it to actuate the jaws for grasping.

Abstract: An applicator for contact lenses. A stem having a bore is provided with a flexible neoprene cap or sleeve on the end of the stem, the cap having an end wall forming a diaphragm which is configurated to have the convex side of a wet contact lens placed against it to be held by surface tension. Within the bore of the stem is a manually actuatable plunger. An opening is provided in the side wall of the stem. The lens carried at the end of the applicator can be placed adjacent the eyeball. By manually pushing in the stem, pressure is developed behind the diaphragm holding the lens to deform it and release the contact lens against the eyeball.

Abstract: The invention relates to cooling towers of the type currently in use for cooling water and/or condensing exhaust steam as for example in association with nuclear or fossil fuel type power plants. Typically towers are very large and very high. The invention embodies an original concept for utilization of such towers, for example hyperbolic towers, for the generation of energy from wind and also for improving the efficiency of the cooling tower. In the exemplary form of the invention a large wind driven rotor is provided to be carried by the tower and to rotate around its axis at the position of the narrowed throat of the tower. Pressure is generated by the rotor and discharged through nozzles arrayed on the inside of the walls of the tower to augment and enhance the draft within the tower.

Abstract: The invention is an improved clutching means for tapping attachments and particularly adaptable in attachments having free axial float. Direct and reverse drive is provided for by way of planetary gears for driving in direct and reverse drive in the exemplary attachment in which the clutching means is embodied. An adjustment is provided for depth. Spring biased clutch drive members are provided for both the direct and reverse drive providing a narrow, neutral position. Each clutch driver member is in the form of a sleeve having a ball race carrying driving balls interposed between axial splines on a driving part and on the driven spindle. The splines have arcuate side surfaces to confrom to the driving balls providing for substantially frictionless drive in both direct and reverse modes, the balls being free to roll. The splines are especially configurated to facilitate engagement of the balls with them.

Abstract: Porous, tubular core sections coated with a semipermeable membrane are joined at their ends by a simplified coupling member. Each coupling member or connector comprises a cylindrical flange member having circularly barbed or serrated nipples which fit tightly into the ends of bores of adjacent core sections. The ends of the cores abut against the circular part of the coupling member. Surrounding the joint thus formed is a flexible, elastomeric sealing sleeve. The nipples on the coupling member are axially slotted and have neck parts of a smaller diameter adjacent the body part of the coupling member providing annular openings between these neck parts and the bores of core members permitting continuous flow of permeate and cleaning solution without there being appendages, cavities, or pockets in which permeate or cleaning solution could be trapped.
