The assembly is constructed to have a resonant frequency which matches the tempo of bouncy popular tunes and remains the same regardless of the weight of the user:  The user first sets his weight and then makes the platform oscillate by flexing his knees and by exerting pressure on a handle which moves in synchronism with, but oppositely to the platform.  The unit can be constructed for use by one ot two persons,  In one embodiment, the platform is fastened at one end of a lever frame, the other end of which is pivoted.  The frame is suspended on elastic springs fastened to a movably slid wose position on the frame is determined by the user's weight.  In other embodiments, a compressed coils spring is employed. Dissipation is provided by shock absorbers.

Abstract: ABSTRACT The invention has an enclosure, a circuit breaker mounted inside the enclosure, and a hand lever rotatably mounted upon a door of the enclosure.  A drive shaft is rotatably attached at a first end to the circuit breaker so that rotation of the drive shaft operates the circuit breaker.  When the door is closed a second end of the drive shaft seats in a socket in the hand lever, and rotation of the hand lever rotates the drive shaft. A spring clip is mounted within the hand lever, and the spring clip grips the second end of the drive shaft so that force applied by the hand lever to rotate the drive shaft may deform the spring clip thereby permitting deflection in a coupling between the hand lever and the drive shaft.  A retainer plate attached to the hand lever catches the drive shaft when the spring clip is deformed by the force and thereby prevents opening of the door as a safety measure.  The drive shaft has a reduced cross-section region between the first end and the second end.  An interlock is mounted in a fixed position with respect to the door of the enclosure, and when the door is closed the reduced cross-section region of the drive shaft is located within an opening of the interlock permitting rotation of the drive shaft, and the interlock prevents opening of the door when the drive shaft is in a position corresponding to an "on" condition of the circuit breaker by catching the second end of the drive shaft.

Abstract: ABSTRACT           This invention relates to a novel process and apparatus useful in determining the approximate bulk density of a wood specimen.  The ability to predict or determine the approximate bulk density of a wood specimen enables field crews to select, through approxi-mate bulk density determinations the wood quality of trees for selective consumption or breeding purposes.          A wood specimen having an axial extent and a known initial volume is rendered incompressible by the appli-cation of a compressive force sufficient to expel sub-stantially all of the free water therefrom.  The approximate bulk density is then determined by dividing the compressed volume of the specimen by its initial volume and if considered appropriate, multiplying this by a constant.  The apparatus is a device employed for applying the compressive force to the specimen whilst permitting the free water to be expelled therefrom whereupon the compressed or final volume of the specimen can be determined.

Abstract: Abstract of the Disclosure A manifold is provided surrounding the casing of a combustion chamber for a gas turbine engine, and the manifold is mounted in spaced aligned segments with couplings between the segments.  Each coupling includes a removable tube connector extending between passageways forming the fuel line in the manifold.  The tube connector is provided with a radial collar thereon, and a sleeve which is adapted to enclose the space between ends of respective manifold segments is also provided with a mating collar adapted to receive the radial collar on the tube connector.  The sleeve is retractable over the ends of the manifold segments, and movement of the sleeve in one direction or the other will also move the tube connector by virtue of the interlocking collars.  The manifold segments are provided with a second passageway for draining leaked fuel.  The space defined by the sleeve is sealed, and fuel can communicate through to the second passageway for drainage outboard of the engine.          The sleeve can be locked in an assembled position, thereby locking the tube connector in a sealed relationship with the ends of the manifold segments within the first passageway.

Abstract: Abstract The invention relates to insulating lightweight refractory materials which are resistant to attack by molten metals, particularly molten aluminum and its alloys and compositions used to form such materials.  More particularly. the invention provides a settable composition which comprises a mixture of ceramic fibres, wollastonite powder and aqueous colloidal silica having a solids content of about 5-25% and preferably 12-15% by weight.  The weight ratio of the ceramic fibers to the wollastonite powder is 0.8-1.2 : 1.5-2.5, respectively.  The composition option-ally contains carbon fibres or metal fibres as reinforce-ments.  The composition can be cast to form shaped products or used as a joining material or as a "face-off" material to protect an underlying article.  When dried, the composi-tion forms a material which is insulating, lightweight and resistant to high temperatures and chemical attack by metals.  The material can be made even more resistant to attack by a silicate and/or fluoride surface treatment. The material is useful for forming items used in metal foundries and the like.

The selection of the minterm con-ductors enable the encoder selection to transmit a plurality of output signal on respective output conductors.  The decoder and encoder sections include a plurality of stages, each controlling a minterm conductor and output conductor in response to the input signals and the selection of the minterm conductor.  The stages include control transistors that are connected between a node, to which the respective minterm and output conductors are connected, and switches which enable and disable the control transistors.  The nodes are initially precharged while the switches disable the respective transistors.  After precharge, the switches enable the transistors in the decoder and encoder section respectively.
