Abstract: A beer dispensing apparatus for delivering beer to a valve that is opened to dispense a predetermined weight of the beverage by monitoring the reduced weight of the supply keg. The apparatus also includes means for bypassing a portion of the beer from the cooling coils so that a part of the beer is cooled to a non-foaming temperature and a portion of the beer is at a foaming temperature. The two portions are mixed into a mixture that forms a head on the liquid received in a beer mug or pitcher.

Abstract: Apparatus for lowering a passenger-carrying gondola from a high-rise building includes a vertical shaft or chute having a vent opening at its upper end, a vent opening at its lower end, and an air motor at its lower end suitable for either delivering air into or removing air from the chute. A passenger-carrying gondola is mounted in the chute such that as it descends under the influence of gravity, it compresses the air beneath the gondola to a pressure depending upon the position of the lower vent. If the lower vent is totally closed, the gondola creates an air cushion which can be controlled to slowly lower the gondola. The descent of the gondola can be retarded by closing the upper vent to create a vacuum above the gondola. When the gondola is descending from a relatively high-rise position, the air motor can be activated to remove the air cushion beneath the gondola so that it descends at a rate greater than a free-fall.

Abstract: A pneumatic construction game comprising a series of connected plastic tubes forming an endless conduit having an inlet opening, a source for delivering pressurized air into the conduit, a body movable in the conduit in response to introduction of the pressurized air, and control vents, upstream and downstream of the inlet opening, to control the motion of the body as it moves around the conduit.

Abstract: Amusement apparatus is disclosed comprising a spherical passenger-holding body, and a vertical tube having a diameter sufficient to receive the body in a vertical path of motion. A turbine for moving air through the tube is located at the upper end of the tube for raising the body from the lower inlet end toward the upper end of the tube. To change the attitude of the body in its raised position, two sets of controls are utilized which are both manipulated by the passenger. Louver members externally mounted permits revolution of the body about its vertical axis by reaction to the air. Two U-shaped members in perpendicular planes are rotatably mounted at their ends in the body. Each has a weight slidable along its member, with the weights pivotally joined to each other.

Abstract: An amusement device comprising a spherical body for holding a passenger, a ground supported base having a semi-spherical seat for supporting the body in a lower position, a source of air under pressure connected to the base beneath the body for raising it to predetermined position supported solely by air, and an upright tube mounted on the base for guiding the body as it is being raised above the base. Movable control members mounted externally and internally of the body permit the passenger to revolve the body in any direction.
