Abstract: An infant feeding bottle that is nipple-equipped at one end that is further equipped with a pressure equalizing apertured diaphragm member at the opposite end. The diaphragm member allows room air to pass therethrough into the air space in the bottle when the bottle is inclined and liquid is withdrawn through the nipple, thereby equalizing the interior air pressure. The diaphragm member is gas and liquid tight when the inside and outside pressures are equal and the bottle is in an upright configuration with the feeding liquid resting on the diaphragm member. The diaphragm member has a central portion which is dome configured and provided with apertures that are in a sealed shut configuration when the diaphragm member is relaxed yet that are opened when the diaphragm member is expanded responsive to differential air pressure.

Abstract: An infant chair structure having upper, lower and interconnecting main frame members, a leg support frame member, and an optional toy bar connector for joining the leg support frame member and the toy bar to desired locations along the upper frame member are provided. The chair structure has decentralized interconnections which avoid the problems of centralized connectors.

Abstract: A chair structure provided which can be used by young children either as a bouncer or as a rocker. The structure is defined by a frame member having a pair of transversely spaced, generally U-configured side portions and at least one seat member raised above a support surface. The frame member is oscillatable or rockable depending upon which one of the opposite end portions thereof is engaged with the support surface. Preferably, the structure incorporates a unitary frame member and single seat cover member that is adapted to slip over either opposite end region of the frame member, whichever one of the end regions is positioned uppermost relative to a floor surface. In one orientation, straightened portions of the frame member are floor engaged causing the upper frame portions to be vertically oscillatable. In a reverse orientation, curved portions of the frame member are floor engaged causing the upper frame portions to be horizontally and reversibly tiltable.

Abstract: A board game combines elements of chance, strategy, and mental ability to connect or bond a sequence of clues. A triangular game board is divided into three quadrilateral playing areas, each with a peripheral game path consisting of squares or spaces. Each player has three transit pieces, one for each of the three pathways. A category die is rolled to select a particular category or obtain a free roll. There is a set of clueset cards, with each card having on its front face a clueset for each of the categories, and, in addition, a challenge clue set. On the reverse are answers to the category clue sets. The game board folds compactly for storage.

Abstract: A compression union for joining two tubing segments together in a sealing relationship. Each segment has a head and a compression shoulder, and a sealing face. A first and second nut are threadedly joined and compress the segments together. The segments pass through respective nuts. A thrust cap is adapted to be firmly clamped. It includes an axially-extending tongue fitted into a respective axial spline, so that tightening the nut together exerts only axial force on the sealing faces, and the thrust cap prevents counter-rotation of the tubing segments relative to one another.

Abstract: A foldable, portable toilet seat is provided having foldable front and rear sections that are pivotably connected by hinges. The lower surface of each front section includes a downwardly extending flange for engaging a conventional toilet seat to prevent slipping or movement. The flange of each front section interfits within a hollow raised portion of the corresponding rear section when the sections are folded for convenient transport and storage.

Abstract: A golf practice mat has an upper surface provided with fixed lines to establish foot and shoulder alignment, swing path guidelines, ball position and unlofting lines in further combination with ball placement markers. Foot position indicia are color-coded to match up with ball placement markers (42) and line-of-flight arrows (38) to promote proper address and body position with respect to the ball thereby aiding a golfer's shot-making ability. The shoulder alignment (26) is closely spaced and parallel to the target line (24) which extends parallel to the intended line of flight of the golf ball. The unlofting line (32) indicates alternate locations for positioning a golf ball if the locations along ball position line (30) are deemed inappropriate, or if it is desired to effectively change the loft of a given club at the point of impact with the ball. In an alternate preferred form, the mat is of L-shaped configuration to leave an open space for placement of the ball to be struck.

Abstract: A booster seat is provided having an inflatable lower portion which can be generally donut-shaped and an inflatable upper portion which can be generally U-shaped. The lower portion and the upper portion are hinged together whereby the inflated upper portion is folded over and is secured against the upper surface of the inflated lower portion to provide a seat pocket in which a child can sit.

Abstract: A combination car seat and stroller having a plurality of wheels which are pivotable between a first, lowered position for use as a stroller and a second, raised position for use as a car seat. An extendable handle is provided for pushing the apparatus when the wheels are in the first, lowered position. A spring or clip is provided for locking the wheels in the first, lowered position for use as a stroller. The wheels are pivoted to a second, raised position to allow the apparatus to be placed on the seat of an automobile, an airplane seat, or other surface. Slots in the arms of the chair are provided for releasably engaging the apparatus with the seatbelt of the automobile or airplane seat. The apparatus is provided with a selectably extendable footrest whch can be retracted when the wheels are pivoted to the second, raised position.

Abstract: A lifting and positioning apparatus particularly suited for use in the installation of wing-mounted airplane engines includes superposed upper and lower load-bearing support platforms that are connected to one another by means of a jack mechanism operable to raise and lower the upper platform while supported by the lower platform. The lower platform includes and is movably supportable on fluid cushion bearings. The upper platform supports a plurality of resilient elastomeric elevator bellows that are positioned and adapted to receive and support a heavy object, such as an aircraft engine, while cushioned against application of excessive lifting force. The bellows are independently inflatable and deflatable to effect raising and lowering of selected portions of the aircraft engine and thereby rotate the engine to desired angular orientations. Alternatively, the bellows may be actuated conjointly to effect uniform vertical raising or lowering of the aircraft engine.

Abstract: A device for diverting exhaust gases from the engine of a vehicle such as an automobile to opposite tread surfaces of the driving wheel tires thereof. The device includes a valve assembly having a body interconnected to the vehicle exhaust system, conduits for diverting the above-indicated gas flow being joined to the body and extending outwardly therefrom. A valve member in the form of a pivoted plate is located within the body and is manually operated to divert the exhaust gases into the conduits for discharge at the driving wheels of the vehicle. The device is useful in removing ice or snow from the driving wheels as well as preventing hydroplaning thereof in wet weather.
