Abstract: Disclosed herein is an apparatus and method for performing a test with a gyroscope in which the apparatus defines a pair of gyroscopes suitably fashioned to rotate in opposed directions, a substrate supporting said gyroscopes, and a bell jar overlying the gyroscopes, along with structure to constrain the bell jar on the substrate. The method disclosed for use with the apparatus includes the steps of spinning up both gyroscopes in opposing directions, securing the bell jar thereover, and providing an energy disturbance a reasonable distance from the apparatus so as to observe any precession which might take place with the gyroscopes due to the energy disturbance.

Abstract: A lock is provided on the stock of a gun defined by a plurality of buttons some of which must be simultaneously depressed in order to release a safety lever so that the lever can be moved from a locked to an unlocked position permitting the firing of the gun either through a trigger or by means of the safety lever.

Abstract: Disclosed herein is an insertable article for altering the cure rate and chemical composition of an object thus pierced which includes an elongated shaft, preferably formed from heat conductive material, and recesses extending along the length of the shaft provided with areas around the recess for the disposition of chemicals therein. The shaft has a terminus which is pointed for ease in insertion into the object, and the support areas and recesses are so disposed on an outer face of the shaft that the cure rate of the article and its chemical configuration is altered by a gradual leaching outwardly of the chemicals and a cure rate pattern altered by the heat conductive shaft.

Abstract: Disclosed herein is a guitar neck and body made from moldable materials such that the finished guitar may be made either solid, semi-solid, or substantially hollow, and wherein the structure further includes interconnection areas between the various components to provide a finished article which can be durable, require less manufacturing processes, while simultaneously providing performance characteristics at least comparable to conventional designs for guitars.

Abstract: A high frequency roll-off circuit for a gain stage including an amplifier having a feedback network together with a dual potentiometer comprising two serially connected gang operated resistors connected between the amplifier feedback port and through a capacitor to the amplifier output port, one of the resistors forming a volume control and the other resistor forming a high frequency roll-off control whereby at high volume settings, high frequency roll-off is automatically provided.

Abstract: A carrier for roller skates including a frame having sides provided with vertically spaced recesses for accommodating the wheel and axle assemblies of a pair of roller skates to support the roller skates in oppositely disposed relationship on the frame together with a releasable locking device on the frame engageable with at least one of the wheel and axle assemblies on each of the skates to retain the wheel and axle assemblies and therefore the skates within the recesses on the frame.

Abstract: Disclosed herein is a bee keeper frame for use as a brooding area within a beehive including a wax brooding foundation fastened to a framework formed from a substantially rectangular grid. The wax brooding foundation is deployed within the frame by means of a guide which has a substantially U-shaped configuration in which one of the leg portions has a greater length than the other. A handle is provided on the guide to assist in removal of the guide when the wax brooding foundation has been properly affixed to a back rail support which forms a portion of the framework.

Abstract: A tree delimber including a frame having a track for guidably supporting a carriage having a boom and grapple assembly thereon, the carriage being driven for movement on the track between the ends of the frame with a tree delimbing assembly at one end of the frame having an articulated chain with blades and an articulated arm with blades which completely surround the peripheral surface of a tree trunk positioned in the tree delimbing assembly by the boom and grapple assembly. The carriage is provided with jaws for gripping the butt end of a tree trunk so that when the carriage is driven along the track, the tree trunk is pulled along the frame through the tree delimber assembly permitting the blades to remove the limbs from the peripheral surface of the tree trunk.

Abstract: Disclosed herein is an abdominal waist exercising device characterized in that exercise motions developed by the working against of weights is ultimately transferred from the back of the knee to exercising muscles throughout the groin area. The machine is comprised of a cushion bar oriented and nested, against the hock of the knee connected by a linkage to a counter balanced cam which in turn is connected by a cable element through a series of pulleys and ultimately to a plurality of weights which are constrained to translate in a vertical direction only. The person using the machine is placed on a bench having a back portion capable of adjustment whereby the back of the person may be offset relative to the horizontal plane. Hand grips are further provided for additional support during the exercise.

Abstract: Disclosed herein is a machine for use in exercising the upper arm area by performing what is known as an arm curl. The machine is defined by a seating area, a pivotable arm support table, and a bar fashioned to comfortably engage the hands of the user. This provides a rotation about an axis which is transferred to a cam whose configuration causes proportional resistance throughout the exercise for maximum arm and shoulder development. The cam is operatively connected to weights through a chain drive and the increasing radius of the cam is that which provides the proportional change and resistance.

Abstract: Disclosed herein is a method and its associated article for forming the neck of a guitar so that a torsion rod disposed within the neck can serve to straighten neck or counteract the tension or bowing effect of guitar strings. The method includes taking two similarly shaped blanks of stock material and routing a center portion complementarily formed to accommodate a torsion rod. Each element of stock material is routed to provide a mirror image of each other and dowel means are essentially disposed to provide further support for the two halves of stock material when they are joined together as by glueing. The terminal longitudinal extent of each of the stock articles is provided with means for retaining the thus assembled stock article for subsequent carving.

Abstract: Disclosed herein is a device that can be used as a magician's prop that in one instance functions as a rigid walking stick or cane, but when released and actuated becomes coiled upon the floor and takes on the appearance of a snake with its head raised. This is accomplished by means of an inner core structure that is comprised of a series of disc like segments strung on a thin cable in a bead like fashion leading to a lever device disguised in the head that when compressed and latched draws the cable taunt compressing the discs one upon another causing the entire length of the body to become rectilinear and rigid in the form of a cane. In the head of the cane the latching device maintains the tension drawn on the cable; however, when unlatched the tension subsides, the discs separate a discrete distance and its body becomes flexible.

Abstract: An apparatus for exercising the calf muscles defined by a framework in which a top extremity thereof is provided with a pair of horizontally extending arms pivoted to a pair of top frame members interconnected and capable of rotation, shoulder pads disposed on the bottom face of these rods at extremities remote from the pivot point, a rigidifying cross brace provided with an opening through which a vertically extending rod is adjustably pinned. This rod traverses through a plurality of weights whose magnitude is selectable and substantially beneath the shoulder pads there is provided on the floor a toe support so that one's toes while standing thereon allows the heel to extend out into space. The exercise is performed by flexing the arch and standing on one's toes which provides tension to the calf muscle.
