Abstract: The pumping or swabbing device and apparatus of the invention utilizes an elongate barrel slidable upwardly and downwardly on an axial rod which carries a valve element for closing on a valve seat provided interiorly of the barrel to close passage through the barrel of down-hole pressure fluid and cause such fluid to raise barrel and rod of the device through a gas and oil well casing to the wellhead, where liquid above the device is pushed to discharge at the wellhead. Spring actuated detent latching elements coact with a pair of longitudinally spaced lower and upper latching recesses to hold the barrel and rod together against relative movement in lower valve-closed and upper valve-opened positions. A sealing packer encircles the barrel and a by-pass passage thereinto leading from and back into the barrel flow passage provides sealing pressure within such packer as the device rises in the well casing. A manually or pressure operated latch provides for holding the device in the wellhead as desired.
Abstract: A bait package for wildlife comprises an odoriferous, effusive attractant material in an absorbent material therefor sealed within an easily puncturable container, which is placed at a desired location and punctured for use. For capturing marine life, such as edible crustaceans, e.g. crayfish, the attractant material may be a fish oil and the absorbent material either a usual bait formulation or an inexpensive, inedible, insoluble material, such as sawdust, and the bait package may be encased by an open weave material that catches the claws of the crustaceans. The bait package may also be covered with a porous material, such as a plastic foam sheeting, to protect the container and to aid diffision of the attractant following puncture of the container. The open weave material encasing the bait package is preferably a reusable case of special formation.
Abstract: A disposable diaper is combined with a reversible bag provided with coactive sealing members bordering and tightly sealing its otherwise open entrance mouth and protectively containing one or more wet wipe pads for use in cleaning an infant following soiling of the diaper. The bag is attached to one panel face of the diaper, either to or as the usual moisture proof backing for the diaper, and is reversible to encompass the soiled diaper and wet wipe pad or pads after use and bundling together. The coactive sealing members are reversibly arranged for ultimately sealing the bag against release of odor. Double tongue members back-to-back on a flexible plastic sheet to be connected to a second plastic sheet provided with tongue-receiving groove members back-to-back constitute an aspect of the invention having broad areas of use.
Abstract: A programmable machine for dispensing items, such as pills or capsules, in timed sequence has a cylindrical container element provided with a series of item receiving and dispensing compartments extending spirally therealong and opening into its circumferential surface for alignment with a discharge opening in a stationary cylindrical shell within which the container element is mounted for both rotary and axial movement concentrically over and along a microprocessor controlled, stepper motor, so as to sequentially bring the individual compartments into precise alignment with the discharge opening of the shell to discharge their contents into a delivery tray. The container element is mounted for spiral movement on and along a stationary spiral trackway as it is rotated. The compartments may be filled by turning the machine upside down and inserting items through the discharge opening.
Abstract: An LED display particularly adapted to be used as part of a design on articles of clothing such as tee-shirts, includes a flexible circuit board to which individual LED dies are secured in desired position. The individual dies are electrically connected to traces on the circuit board and are encapsulated on the board so as to protect the individual dies and connections and so that the encapsulating material forms lenses for the dies. In most instances, the display so formed will be completely covered with a protective layer of covering material having a design thereon and having transparent or translucent means over the encapsulated LED dies so that light given off by the LEDs is transmitted through the layer. Control circuitry is provided to supply power to the LEDs, preferably in a predetermined pattern, to cause them to illuminate.
Abstract: A heat exchanger for use for example in a laundry dryer comprises a plurality of plates defining flow passages therebetween for a first heat exchange medium. Each plate is made up of a plurality of aluminum elements having mutually co-operating positive and negative profilings at their narrow sides, to fit snugly together. The plates are held at a spacing from each other in grooves in end wall members forming a holding assembly. A second heat exchange medium flows through the hollow interiors of the elements making up the plates. The hollow interiors have web portions therein, to enhance heat flow between the first and second heat exchange media.
Abstract: A self-contained cooling device for cooling the contents of an open container includes a cooling portion which, upon activation of the device, is cooled below ambient temperature and a handle portion secured to the cooling portion but insulated therefrom so that a user can grasp the handle portion and insert the cooling portion into the contents of an open container to be cooled and manipulate the cooling portion in such contents. In a preferred embodiment of the device, the device takes the form of an elongate rod similar to a stir stick which can be inserted into ad stirred about the contents of a container to be cooled.
Abstract: A liquid heating apparatus comprises a container or vessel having disposed therein a tubular heater member which is bent in a double loop configuraton with a raised central portion thereof being welded or soldered in a strip configuration, having low thermal conductivity, that substantially bridges mutually spaced ends of such tubular heater member which are attached to a mounting plate supported by the container. A thermally actuated cut-out switch bears against the plate from the outside of the container and is adapted to respond in a sensitive fashion to heat transfer from the adjacent central portion of the tubular heater member in the event of thermal overloading or running dry of the tubular heater member.
Abstract: The invention is a method for transporting and for treating during transport a gas containing potential atmospheric pollutants, including carbon dioxide making use of the extensive heat exchange area so provided, to obtain either a clean-burning fuel gas or a residual gas that can be discharged into the atmosphere without danger of significant atmospheric pollution. A cross-country pipeline is structurally modified or initially constructed to circulate coolant fluid along circumferential positions thereof, preferably by externally jacketing such portions and circulating coolant fluid therethrough, and to provide a gravity settlement chamber therein for carbon dioxide snow and particulate matter and a mechanical arrangement, such as a ram, for pushing any previously precipitated matter into such chamber.
Abstract: An apparatus for increasing the vertical travel of auxiliary wheels mounted on an auxiliary axle includes a lever rotatably mounted on the auxiliary axle and a wheel mounting spindle secured to the lever spaced from its mounting on the auxiliary axle to displace the wheel from the axle. In a preferred form of the invention, the lever is mounted on the axle by being secured to the end of a second axle rotatably mounted within the hollow auxiliary axle. Apparatus is provided to cause rotation of the lever between a lowered position in which the auxiliary wheels can be moved into weight bearing position and a raised, increased clearance position. A lock is provided so the lever can be locked in position, at least when in lowered position. In some cases, the lever will be mounted to the axle in a manner to allow the auxiliary wheel to caster and thereby steer with the vehicle on which it is mounted.

Abstract: A platen for use with a conventional screen printing machine for printing designs or patterns onto garments includes a window or windows formed in the body of the platen. The windows permit backlighting therethrough and through the garment material to enable the positioning and registration of a pattern on one side of a garment (the front side, for instance) to be registered with a pattern to be printed on the opposite side of the garment. The platen windows may be formed of a plexiglass material, either transparent or translucent, sufficient to permit light to pass therethrough. Light sources are positioned directly below the windows of the platen to enhance the backlighting effect for more accurate registration of patterns to be printed on the garment. A closed loop frame is adapted to fit around the periphery of the platen to hold a garment in position on the platen during the screen printing process.
Abstract: For sequentially dispensing individual closed loops of a narrow, easily tied, flexible material, such as dental floss, a chain having such closed loops as respective links thereof is made up by pressing a loop length of the flexible material into substantially rectilinear formation, loosely forming a knot in an end thereof, inserting a loop end of another so-pressed loop length into the loosely formed knot of the first loop length, tightening the knot to provide a slip-free-until-pulled-to-separate-loops joinder between the thus formed loop links and repeating this with additional loop lengths at either or both ends of the first-joined loop length until a chain of desired length is formed. Individual loop links are dispensed by grasping a terminal loop link of the chain and pulling it free of the chain while holding the knot that embraces the unknotted end of the next loop link of the chain.
