Abstract: An item of personal accessory baggage has a user-recordable electronic sound recorder and playback device sized to less than 30% of an available carrying volume of the baggage, that reproduces a sound stored by a user and that is actuated upon occurrence of an event other than a movement of the baggage. The baggage preferably has a flap and at least one shoulder straps. Exemplary pieces of baggage are children's knapsacks and woman's or girl's pocketbooks. The recorder/playback device should have sufficient capacity to record at least 120 seconds of speech, although both greater and lesser capacities are also contemplated. The recorder/playback device may have any suitable actuation/control mechanism, and preferably uses a light actuated sensor. The recording/playback device may be constrained to the designated location by mechanical constraint (e.g., a sewn seam, a pouch, Velcro™, etc), a magnet, or chemical (e.g., glue, adhesive, etc).

Abstract: Disclosed is an audio compact disc that includes a number of audio tracks, at least a portion of which are to be played at predetermined times when the audio disc is installed in a compact disc jukebox or similar player. Stored on the compact disc is a value indicating that at least a portion of the audio tracks are to be played at predetermined times. The stored value also specifies a predetermined sequence or play schedule that is to be used with the compact disc. When the compact disc is installed in a compact disc jukebox, the stored value is accessed by the jukebox controller and causes audio tracks that are scheduled for playing at predetermined times to be played at that time or immediately after any audio track that is being played at the predetermined time.

Abstract: An aircraft propulsive power unit comprises an engine, a nacelle structure which houses the engine and which includes displaceable nacelle portions which form a forward part of the nacelle structure and which take up operational positions in which a forward end of each nacelle portion forms part of an intake opening which leads to an intake barrel which is located upstream of the engine for the supply of intake air to the engine and which is secured to a forward component of the engine. Each displaceable nacelle portion includes a lipskin structure which has rearwardly extending outer and inner lipskin edge portions, and further includes an outer main skin.

Abstract: An apparatus and method of scheduling audio tracks on audio compact discs in a CD jukebox to be played at predetermined times is disclosed. The method includes storing, in a CD audio track index location on an audio CD, a value indicating that the audio CD is a sequence CD containing audio tracks that are to be played at predetermined times. The stored value also specifies a predetermined sequence, or schedule to use with the sequence CD. A controller computer, within the CD jukebox and external to the CD player, utilizes CD-DA commands to query the CD player for the CD audio track index on each audio CD. The responses are used to distinguish normal audio CDs from sequence CDs. A periodic interrupt invokes a sequence interrupt handler that determines whether any audio tracks on any sequence CDs are scheduled to be played.

Abstract: In a method for removing dimethyl ester vapors or particles emitted from a molten dimethyl ester storage tank, a gaseous mixture containing dimethyl ester vapors or particles and an inert gas are supplied to an inlet port of a water scrubber. Water is continuously sprayed through downstream spray nozzles located inside the water scrubber whereby the water and air mix with the gaseous mixture to form a foamy mixture of dimethyl ester, air and water. Water through an upstream spray nozzle located inside the water scrubber is intermittently sprayed to wash an inner wall of an elongated body and the inlet port of the water scrubber to remove buildup of dimethyl ester particles. The foamy mixture is continuously removed from an outlet port. The water scrubber utilized in the method has an elongated body having an inner wall, a top with an orifice for receiving air, and a bottom with an outlet port. The inlet port is positioned on the body between the top and the bottom of the water scrubber.

Abstract: A combination vacuum cleaner and blower is described which is particularly adapted for use as an accessory to a fireplace. The apparatus of this invention is a portable hand-held vacuum/blower which is controlled by a reversible fan motor. When operating in a first direction, air is sucked into the vacuum preferably to clean up ashes around the fireplace. A valve is provided to prevent air from being sucked in the blower. When operated in a second direction air is blown out the blower exhaust and can be used to blow air on a fire. A second valve is provided to prevent air from being blown out of the vacuum inlet.

Abstract: The paper-making stock on a paper machine is improved by running the forming fabric, carrying the stock, as a layer of a dilute aqueous dispersion of fibers, over a modified low-vacuum suction box having a slotted cover made up of elongated blades dividing the suction area into a grid. The surfaces of some of the blades support the fabric and the surfaces of others are lowered a small amount to allow the fabric to undulate and agitate the stock without substantially changing the grid area of the drainage surface. The lower level surfaces form a fluid seal with the undersurface of the fabric.
