Abstract: The following specification discloses a universal guide or pattern for use with a panograph. The panograph can comprise a number of arms that are interconnected at hinge points that support a spindle having a cutting tool for milling or cutting a circular, ornate, or eccentric shape, as well as angles and lines. The spindle with the cutter correspondingly follows the movement of a stylus that overlies the universal pattern that is formed with an arm that guides the stylus in either a two or three dimensional pattern. The pattern is formed in part on a plate having a centrally oriented pin or support post that holds a rotatable arm having a scale thereon. The rotatable arm has a pair of stops that can be set along its length at different locations with respect to the scale. The panograph stylus can be implaced within a stylus holder that moves along the arm between the stops or within the stylus holder that is secured by a set screw.

Abstract: The following specification discloses a vehicle reinforcing bar that can be used with a pickup truck body. In particular, one of the members of the bar is a U shaped member having mounting plates upon which it stands in the bed of the pickup truck. A pair of angularly oriented bracing members is attached at its ends both to the cross member of the U shaped member and to the bed or wheel wells of the truck. The bracing members are pivotally attached to the cross member of the U shaped member by means of collars. The pivotal mounting permits free rotation of the bracing members around the cross member. This allows the entire brace to be folded into a flattened configuration for shipment until it is installed in a truck. Upon installation by attachment of the free ends of the bracing members to plates on the wheel wells, the bracing members become fixed relative to the cross members, precluding further rotation.

Abstract: The following specification discloses and teaches a solid state ringer or audible alarm for a telephone. The ringer can be connected to the tip and the ring sides (i.e., plus and minus terminals) of a telephone network in the home, or any other location. The ringer incorporates a rectifying bridge and a two terminal current regulator for providing current to the network on a regulated basis to eliminate undue irregularities on the line. The ringer can be rung on a duty cycle similar to a mechanical bell by means of charging a capacitor that discharges in accordance with the duty cycle of the mechanical ringer. The cycle is established through a timing network formed with a resistor within the timing loop incorporating the capacitor. The capacitor is discharged to power a speaker through a switching network by means of three transistors that provide a switching function. The discharge provides a voltage across an oscillatory network that allows a unijunction transistor to operate a speaker.

Abstract: The following specification discloses a pipe joining and connection process and apparatus for utilization with all forms of plastic pipes and metal and plastic pipe couplings. The joint comprises a plastic or metal adapter fixture which has been swaged in circumferential relationship to the pipe by expansion of the pipe into the fixture through a process and apparatus which serves to expand and hold the two elements together. The apparatus comprises a metal sleeve on the interior of the pipe and an exterior metal retainer overlying the fixture to provide the necessary hoop strength surrounding the joint. The process is effectuated by means of expanding a resilient elastomer within the bore of the pipe against the sleeve that is concomitantly expanded outwardly against the pipe. The plastic of the pipe is simultaneously caused to flow into grooves within the fixture.

Abstract: The following specification describes a rotor and case in a gyroscopic device generally forming a ball-shaped apparatus having an internal circular race. The internal circular race supports the rotor, which is mounted on a shaft that extends through the rotor and is received in an opening of a T-shaped cross sectioned ring which is placed within the race. The rotor rotates through the spin axis thereof, while at the same time a second axis at right angles that intercepts the spin axis is established around which the rotor will precess. By giving the rotor an initial spin and then holding the support structure or ball in the hand and manually applying a torque to the support structure or ball, the rotor will precess about the second axis of precession and produce a torque opposing the manually applied torque. The rotor is provided with fins for maintaining the rotor in a smooth moving configuration, while at the same time cooling the spinning rotor so as to eliminate frictional wear.

Abstract: A laminating material such as a fibrous glass formed as a woven fabric or chopped strand mat which has been coated with a plastic resin on both sides thereof. The plastic resin is applied so that it does not permeate the fibers of the reinforcing material but is only adhered on the surfaces thereof. The resin coating is maintained intact on the reinforcing material by incorporation of a fine light mat, referred to as a carrier, in the resin coating.The reinforcing material can be made by initially laying down a resin coating on release film, together with the carrier. After processing of the resin to its final tackiness required for laminating, the resin sheet is adhered to one or preferably both surfaces of the laminating fabric.

Abstract: The following disclosure discloses a buoyancy compensator having an inflatable bladder at the front and rear of a diver, so that adequate buoyancy is provided with respect to the diver's entire torso. The buoyancy compensator has a strap and harness arrangement that incorporates securement of a backpack thereto for an underwater breathing gas tank that is strapped thereon. The buoyancy compensator includes a low pressure inflation system, an oral inflation member, and a valve for releasing excess pressure either through overexpansion or by manual articulation of the valve cover. A low pressure inflation system for the buoyancy compensator utilizes exhaust breathing gas for pressurization of the buoyancy compensator from the second stage regulator exhaust. The exhaust flow into the buoyancy compensator can be controlled as to pressure and displacement by a pressure relief valve and switching and valving manifold control system.

Abstract: This disclosure encompasses a cable lock which is particularly suited for securing a bicycle. The lock employs a continuous cable which is wound around a cylinder which is contained in a housing. One end of the cable enters the side wall of the cylinder and exits through an open end. The other end passes out through a hole in the housing. A spring, wound around another portion of the cylinder, maintains a spring load on the cable. Thus, retraction of the cable is possible upon extension and release thereof. The ends of the cable are fashioned into loops which are of a size to maintain it outside of the housing. In the locked condition, the loops are secured by a padlock. A mounting bracket as well as a flange with an opening for storing a padlock is also provided.

Abstract: The invention as disclosed in the following specification, relates to a heat exchanger, having tubes fitted into plates, that exchange heat from a gas passing thereover to fluids passing through the tubes. The heat exchanger is particularly adaptable to boilers having fire tubes and other types of boilers wherein the heat applied to the tubes is circulated and then exhausted. Prior to exhaust, the heated gas is passed over the plates in a duct. The tubes in the plates are used to pick up the heat from the exhaust gases by means of the feed water passing through the tubes, or the tubes can be used to directly heat other fluids, such as oil and service hot water. A damper is placed over the normal exhaust gas flue in conjunction with a second damper or duct control system whereby an exhaust fan on the downstream side of the heat exchanger duct provides a constant draw to allow the boiler to operate within its normal pressure ranges.

Abstract: The following specification discloses an aerodynamically driven toy that can be in the form of a toy or other animal having a moving appendage such as a tail or wing. The wing, tail or other appendage is driven aerodynamically when passing through a relative wind by virtue of the fact that a turning moment is applied respectively for both negative and positive angles of attack after the appendage, such as the wing of a bird, has been moved through the reverse of the foregoing movement. The angle of attack is changed by virtue of an operating arm that is linked to the wing or appendage so that it moves in a manner whereby the wing will be positively driven upwardly and downwardly at the respective low points and high points of the travel of the wing. This is done by means of turning the wings in a direction to apply a certain angle of attack so that the relative wind will pick up the wing when it is in its lower position and depress it when it is in its upper position.
