Abstract: An acoustical horn speaker for producing low distortion sound comprised of a casing assembly having a voice coil gap and a magnetic source and return circuit for providing a constant magnetic field across the gap, a current-carrying voice coil disposed in said gap, and a voice diaphragm in rigid attachment with the voice coil, said voice diaphragm being suspended from the casing assembly by a relatively flexible, high compliance suspension member. An acoustical horn having a throat resistance sufficiently high to substantially dominate the radiation resistance of the diaphragm is air coupled at its throat end to the voice diaphragm suspended from said casing, while the compliance of the voice diaphragm suspension is relatively high such that in the presence of the dominating throat resistance of the horn the diaphragm vibratory movement is characterized by substantially force determinative excursions as opposed to substantially linear constant displacement excursions.

Abstract: A method for electrically cracking crude oil comprised of the steps of injecting a mixture of petroleum crude and an energy transfer medium into a cracking chamber in a continuous flow, supplying a high frequency electrical discharge into the energy transfer medium which, in turn, consecutively transmits the energy to the petroleum crude for cracking, and extracting and storing the component hydrocarbon fractions while separating out the energy transfer medium.

Abstract: An abrasive blast system comprised of an abrasive media holding tank, a pressurized air supply, a remotely controllable inlet and outlet valve means for pressurizing and depressurizing said holding tank, a remotely controllable abrasive flow control valve capable of modulating the flow of the abrasive blasting media, and a remote control valve disposed to be operated by the operator of the abrasive blast system for remotely controlling the inlet and outlet valve means, as well as the abrasive flow control valve.

Abstract: An improved exercising device comprised of a body support belt having an inner, relatively wide, and rubber-like body engaging band and an outer substantially inelastic reinforcement material, and further comprised of a relatively wide rubber-like wrap band secured to and extending substantially beyond the body support belt, and an elastic cord member attached to the ends of the body support belt which can be releasably hooked to a doorknob or the like whereby, when a user wearing the body support belt and wrap band jogs in place against the tension of the elastic cord member, the rubber-like body engaging band and wrap band evenly distribute pressure over the contacted portion of the body and insulate the user's midsection to induce sweating.

Abstract: A log sawing attachment for a chain saw which includes a moveable guide frame which can be clamped to the cutter bar of the chain saw and can be variably spaced therefrom. The frame guides the chain saw to make pre-selected depth of cut along the log being sawed to form a uniform thickness board.

Abstract: A board game which utilizes owner operated businesses to maximize a player's financial worth at the expense of opponent players comprised of apparatus for identifying each player by a fictitious name prior to commencing play, tokens for each player, bogus money, and a game board having a continuous play field divided into play spaces wherein the play spaces include spaces representing businesses identified by the fictitious name to a particular player which are subject to acquisition and operation by the player so identified as against opponent players, and businesses not identified to any particular player subject to acquisition and operation by any of the players as against opponent players. Also provided is a chance device for advancing the player tokens around the play field of the game board.

Abstract: An apparatus for handling toy and sport flying discs including a ring secured to a shaft with a roller rotatably mounted on the shaft to permit a flying disc to continue to spin after it has been caught on the apparatus.

Abstract: A foldable mudflap assembly for retractably disposing mudflaps behind the wheels of a truck or the like comprised of an elongated support member adapted to be attached to the truck between and proximate the truck's wheels, an elongated extension member pivotally connected to each end of the support member such that mudflaps attached to the extension members can be pivotally extended into an operative position behind the truck's wheels or to a retracted position between said wheels. The mudflaps are releasably locked into their extended operative position by providing guide plugs link connected to the extension members and slidable within the support member; a releasable stop member is in turn disposed to engage the guide plug within the support member to prevent axial movement thereof. Simple mating hooks are provided to lock the mud flaps in their fully retracted position.

Abstract: A self-cleaning muffler for an abrasive blast system comprised of a chamber element having side walls, an end wall, and an inlet portion opposite said end wall, means for attaching the inlet portion of said chamber element to the exhaust outlet means of the abrasive blast system, perforation means in the chamber element side walls to permit gaseous media to escape from said chamber element, but preventing particulate media from passing therethrough, a particulate media outlet means in the end wall of said chamber element, and means for closing said particulate media outlet means substantially during exhausting of the abrasive blast system and opening the particulate media outlet means when the abrasive blast system is not exhausting.

Abstract: An electronic acupuncture point finder comprised of a point finder electrode for passing over a patient's skin, a grabber electrode formed to be secured to or held by the patient, and a balancing and sensitivity adjustment circuit electrically connected to said point finder and grabber electrodes so as to produce an imbalance signal when the point finder electrode passes over an acupuncture point. An amplifier circuit is provided in connection with the balancing and sensitivity adjustment circuits such that the amplifier is only turned on when the body impedance is below a preselected level whereupon the amplifier circuit generates an amplified signal for driving audio and visual indicating circuits.
