Abstract: An apparatus for throwing an object is mechanically operated and utilizes spring tension to throw an object from a tube which is connected to the spring. The apparatus comprises a base, a frame, apparatus utilized for maintaining the frame at an operating position, a tube and at least one spring. An operator inserts an object to be thrown into the tube, manually moves the tube to a preselected cocked position against spring tension and then releases the tube.

Abstract: A telescopically moveable support member has a work element connected to a first end thereof. A rail and slotted collar arrangement is associated with the support member and bumpers are connected to the work element to prevent damage to both the work element and vehicle to which connected during movement from the extended position to the retracted position.

Abstract: A manual throttling system for electronically controlling the speed (RPM) of an engine from a remote location relative to the primary engine controls. The engine controlling signals are responsive to rotational speed and direction of rotation of a manual control knob and the frequency of light pulses of an optical encoder.

Abstract: The apparatus of this invention has a handle connected to first and second spaced apart spray tubes which are rotatable for passing fluid sprays toward one another or in a common direction outwardly from the apparatus. The handle is connectable to a pressurized fluid source. The apparatus is adapted to decontaminate or clean articles passed between the spray bars and clean articles adjacent the apparatus.

Abstract: An apparatus and method for therapeutic ultrasound treatment using a plurality of spaced apart piezoelectric crystals sequentially activated for a preselected time, thereby allowing the transducer containing the piezoelectric crystals to be used substantially stationary relative to the area being treated.

Abstract: A connector is provided which has a ferrule forcibly, intimately connected to a plastic optical fiber by forcibly deforming the ferrule into intimate contact with the plastic optical fiber over a preselected length. The fiber and ferrule are free of adhesive, have a machined planar end oriented 90 degrees relative to the axis of the ferrule and plastic optical fiber and have a preselected, carefully controlled length.

Abstract: An apparatus for removing moisture from a hearing aid by positioning the hearing aid in a chamber of preselected volume and passing heated air over the hearing aid and maintaining the first chamber within a preselected temperature range.

Abstract: A hand held mechanical apparatus for propelling a ball toward a person so that the person can gain experience in hitting and fielding, the apparatus has a tube for holding the ball and a spring for generating the energy to propel the ball from the tube.

Abstract: A method and apparatus is provided for countering asymmetrical aerodynamic forces subjected onto an aircraft. Asymmetrical forces are counteracted by this invention automatically by selectively actuating force inducing elements in response detection of one of (a) differential longitudinal forces induced upon the aircraft by the engines and (b) undesirable rotation of the aircraft about longitudinal axis "c" of the aircraft. The force inducing elements of this invention function independent of primary control elements and other control surfaces of the aircraft.

Abstract: A football training and evaluation apparatus has a frame, a contacting element, and a force transferring member connected to the frame and the contacting element. A measuring-signaling element is connected to the force transferring member and is adapted to measure the force subjected on the force transferring member in response to an impact force subjected onto the contacting element and deliver a signal "S" responsive to said measurement. A visual signaling apparatus is connected to the frame and adapted to be actuateable and moveable in response to actuation.

Abstract: A powered, portable, metal bending apparatus has first and second end plates on opposed sides of a carrying element that is moveable along guiding members. A second surface of the first guiding member and the first surface of the carrying element have opposed first and second die parts adapted to bend metal strips therebetween in response to actuation of a mechanically actuated hydraulic jack which has an extendable length not greater than 8 inches and the construction of be apparatus adapted to weigh less than 50 pounds. The carrying element has arcuate corners and is nested between the guiding elements. The apparatus is designed to bend horticultural metal edging strips or other elongated metal elements to preselected angles of 90 degrees or less.

Abstract: An improvement in a thermally insulating component for an engine part, made by sintering from ceramic materials, comprises, the thermally insulating component having a composition, consisting of a mixture of zirconium oxide in the range of about 5% to about 25% by volume and mullite in the range of about 75% to about 95% by volume. Further, the mixture of zirconium oxide and mullite is obtained by chemically mixing the zirconium oxide and mullite in their molecular states, rather than mechanically mixing them. Another feature of this invention includes, forming said thermally insulating component by slip casting and pressureless sintering the mixture of zirconium oxide and mullite at a temperature no greater than 1700.degree. C. This improvement in a thermally insulating component for an engine part, made from a mullite-zirconia ceramic composite, embodying the present invention, is particularly useful in making flame decks for cylinder heads, and insulating coverings for pistons and exhaust ports.

Abstract: A controllable animal access system connectable to the door of a building which has an opening covered by a pivotally moveable animal door. The animal access system has a motion detector associated with a reader which detects an encoded pet tag worn by a selected animal and actuates locking and unlocking mechanisms in response to reading an accepted code. Various other controls are provided for operation of the apparatus.
