Abstract: Containers for storing various pills are provided which have excellent water vapor permeation resistance and which includes child-resistant opening features. The container includes a top and a bottom which are adapted for telescopic positioning with respect to each other in a generally flush-like manner so that edge exposures are kept to a minimum and the top and bottom each include means which are brought into inter-engagement to define a sealed internal chamber for storing tablets, such as aspirin. Wall portions of the top and bottom are configured to preclude opening of the container except by exertion of a compressive force at selective locations. Such selective application of compressive force between the top and the bottom allows the top to be removed from the bottom in a generally pivotal lever-like manner about a hinge connection by the engagement of a fulcrum surface on the bottom with the internal surface of a portion of the top.

Abstract: An improved home canning closure system is provided for a home canning jar featuring a plastic ring and a metal lid combination which is adapted to allow excess pressure to escape while preventing the escape of the contents from the container. The plastic ring includes an annular top panel portion and a skirt portion depending downwardly from the outer periphery of the top panel portion. The skirt portion incorporates buttress threads on its inner surface to engage threads on the external neck of the home canning jar. The plastic ring features an upwardly and outwardly inclined ramp portion on its lower surface and a thin section at the junction of the top panel and skirt portions which combine to form a spring member to maintain a constant force to bias the metal lid into sealing engagement with the upper rim on the home canning jar.

Abstract: Method and apparatus for handling a plurality of glass containers moving on a conveyor at spaced intervals to a coating application area where three containers are simultaneously grasped about their side walls, retracted laterally from the surface of the conveyor, then moved through a 90.degree. arc such that the containers exhibit horizontal axes one above the other and then moved into position between three heel and neck-engaging chucks carried by an indexible turret. The bottles are released to the chucks which are cam actuated in timed relationship with respect to the grasping means so that the grasping means will release the containers or bottles to the chucks. With the chucks holding the bottles in horizontal position, the turret rotates about a horizontal axis parallel to the axes of the bottles through an arc of 90.degree.

Abstract: A method of heat shrinking a sleeve of pre-oriented polyolefin plastic over the outer surface of a bottle by heating the plastic in annular regions along the height thereof in successive stages while conveyed in vertical upright position along the length of an oven. Infrared radiant heat is directed onto a mid body annular region of the plastic sleeve overlying the large dimension of the bottle. The mid body portion is firmly shrunken around this region of the bottle. Also, the first zone of the oven applies some heat in an upper annular region of the sleeve to soften the plastic thereat and raise its temperature to near the shrinking condition while the bottle and sleeve are rotating at a speed that will hold the upper region opposite the neck of the bottle erect and avoid foldover or collapse. Next, the bottle is conveyed in front of infrared burners in a second control zone of the oven, wherein the radiant heat is directed individually against the upper and lower annular regions of the sleeve.

Abstract: An evacuated, double wall, tubular solar energy collector having a concave, specular reflecting surface corresponding to a segment of a cylinder positioned at the opposite side of the collector tube from the sun. The reflector is detachably connected to the tube and the tube is engaged by raised spacing points on the reflector to provide the proper spaced relation between them and allow for water drainage along the reflector. Plural units of the collector tube and cylindrically-shaped reflector combination are supported along opposite sides of an elongated manifold for circulation of an energy absorbing media through them. This system improves the efficiency of total energy collection without tracking the sun or focusing the reflected radiation. The tubes are no more than three diameters apart and the cylindrical reflector has its focal line within the absorbing area of the collector tube.

Abstract: An improved shell mold and method are provided for thermal conditioning a thermoplastic parison prior to blow molding the parison into a hollow container and especially a biaxially oriented container. The mold has an inner shell and an outer shell defining a passageway therebetween for a circulated heat transfer fluid. Heat transfer between the fluid and the parison is controlled to adjust the thermal history at different locations of the parison as it will be required by the mode of stretching and the blow out ratio at the different locations.

Each spray head is composed of a pair of blocks each having a passage, drilled therein, one communicating with air and the other with liquid, the blocks being separated by a pair of shims, with the shims having cut-out portions respectively to serve as exit openings for the combined air and liquid spray.

Abstract: A tractor drawn implement having a blade engageable with the ground and adjustable as to its depth of engagement whereby depth is increased over high spots and depth is decreased over low spots to transfer soil from high spots to low spots as the implement traverses the ground. A gauge frame trails a main frame carrying the blade and is coupled to a gauge beam whose elevation with respect to the main frame is altered as a function of the elevation of the gauge frame relative to the main frame and/or blade. The gauge beam is coupled to the gauge frame so that the articulation between the gauge frame and main frame provided for convenience in manipulating the implement and the freedom of transverse motion between frames is enabled without displacing the gauge beam from an operative relationship with control elements adjustably mounted on the main frame. Electro-hydraulic controls are illustrated.

Abstract: An appliance comprising a unitary, atmospheric pressure, equalization chamber and drying chamber in the form of a sealed, flexible walled container is provided with means communicating from its interior to the space between a double glazed window. A separable coupling between the container and the space permits replacement of the appliance when its drying capability is exhausted. Window frame contructions unobtrusively incorporate the appliance in a cavity which has a removable cover. Variations in atmospheric pressure are balanced within the space between the window lights by changes in the atmospheric pressure on the flexible walled container while such changes transfer gas between the space and the container to expose it to the desiccant. One separable coupling passing the gas is a hollow needle inserted through a resilient, self-sealing, passage which can be integral with a seal gasket between the lights.

These glasses represent an improvement over sodium aluminosilicate glass electrodes of the type disclosed in U.S. Pat. No. 2,829,090.

Abstract: A noble metal-glass composite is screen printed on an inert substrate such as a low alkali glass and fired to provide a solid sensor electrode.

Abstract: An arm rest assembly for seating structures pivotally mounted on the upstanding sides of the back support for a seat and arranged for movement in an arc generally normal to the back from a retracted position in which its arm supporting surface is generally parallel to the back and extends toward the seat to a position in which the surface is generally perpendicular to the back and to a position in which the surface defines an acute angle with the back. A detent in the form of cooperating abutments on the pivotal elements providing the arcuate motion and resilient biasing means tending to displace the elements axially of each other enables the arm supporting surface to be latched in the perpendicular relation. In the parallel relation the arm rest element tends to conform to the seat back since it has a stiffening web depending from the arm supporting surface along its length on the side outward from the region occupied by a seat occupant to effectively wrap around the front and side portions of the seat back.

A unitary piece of finished backing fabric is attached on 3 sides to the edges of the backing fabric in order to provide a means of mounting the cushion element on a seat frame.

Abstract: Several embodiments of inflatable trousers and their auxiliary equipment are disclosed whereby the trousers are inflated in a controlled and precise manner. The form of the garment facilitates application to an infirmed individual by having a front and rear panel which are integral along the inseam of the legs, are separate at the top of an abdominal region, the region of the perineum and at the bottoms of the legs, and are separable along the outer side margins from the top to the bottoms of the legs. Fasteners such as slide fasteners are provided for selective closure along the outer side margins of the garment. One or more inflatable chambers are located within the garment to extend over substantial regions thereof and impose pressure over the enclosed body portion as the entire enclosed abdominal area and both legs or, selectively, the respective legs and an abdominal region. A relatively rigid outer reinforcing panel militates against ballooning in the abdominal region.

Abstract: The features of the invention are illustrated in a preferred embodiment which provides novel apparatus for carrying out the method of automatically beveling the edges or rims of television picture tube funnel or viewing panel components. The components are delivered to an input station from which they are successively transferred to an edge beveling station. Each component is clamped at the beveling station with the rim at a predetermined height. The rim edges are contacted with edge beveling means also located to bevel at the same predetermined height. The edge beveling means and the rim are moved with respect to each other at the predetermined height until the beveling is completed to obtain a uniform bevel completely around the rim. The completion of the beveling operation is sensed to release the clamping of the component at the beveling station and the beveled component is transferred to a discharge station.

Abstract: A motor driven refrigeration compressor having a cylinder head and base of laminated construction. The laminations are formed from flat sheet stock with apertures which define inlet and outlet ports and passages for refrigerant flow. The base is bell shaped and the enclosed end contains integral inlet ports and passages which direct refrigerant past the motor and into the compressor. The base walls contain integral outlet passages which convey the refrigerant from the compressor to an outlet tube in communication with a condenser. Both the inlet and outlet passages contain noise reducing cavities which decrease the effect of the pulsations inherent in a piston-type compressor.

Abstract: A glass melting furnace in which glass can be heated by sources below its upper surface, as electrically by Joule effect, and by means above its upper surface, as by fossil fuel firing or by heat reflectors. A cold top melting mode is employed in the charging region of the furnace while the glass discharge region maintains an exposed molten, upper surface on the glass. In a disclosed embodiment a high crown over the charging region enables cold top melting and refining to be accomplished by Joule effect while flues and burner ports in that region are closed. A low crown, which may be adjustable in its height above the glass line, is provided over the discharge region to increase heating at the exposed, molten upper surface of the glass by reflection. Heating in the discharge region can be augmented by above surface heaters distributed across the crown. A flue in the discharge region carries gases from that region.
