Abstract: A machining and augering bit, particularly adapted for earth cutting, has a dual-headed tool holder. Each head receives a work piece which carries a rotatable tool bit. The head includes spaced apart first and second portions, the interior surfaces of which are opposed and which define a work-piece receiving area. A work-piece is received in the area and is utilized to mount to the tool a carbided throw-away cutting bit. With the cutting bit mounted on the work-piece which is seated in the area one of the portions shields a portion of the cutting bit to prevent its exposure to flying debris, as well as the area to be drilled.

Abstract: A trailer hitch having an incrementally, vertically adjustable ball is disclosed. The hitch includes arms which interconnect the hitch to the hydraulic arms of a tractor. The adjustable ball receives a socket of an agricultural implement.

Abstract: This invention relates to loudspeaker diaphragms and methods of making such diaphragms. It is an object of the invention to improve damping of standing waves formed in a loudspeaker diaphragm. To this end a diaphragm in accordance with the invention is made of textile material impregnated with a stiffening material which does not completely fill the spaces between the threads of the textile material, said spaces being partially filled with damping material. The textile material is preferably a woven glass-fiber fabric or a fabric woven or knitted from an aramid fiber. The stiffening material is preferably a synthetic resin, for example, a phenolic, epoxy or melamine resin and the damping material is preferably a polyvinyl-acetate emulsion or a vinyl resin-based thermoplastic material of the kind used as a cone edge dampener.

Abstract: A polygonally shaped panel or fabrication device having a depending curled locking means formed at at least one edge of the panel is disclosed herein. The locking means is contiguous to and substantially co-extensive with the edge associated therewith. The curled locking means may include a plurality of apertures randomly distributed about the circumference thereof. A plurality of the present panels are deployed to form an interlocking and interconnecting system in a free form array which can be used as a toy construction, as a display system and, preferably, in the fabrication of modular structures.

Abstract: An endless belt conveyor extends from below a rolling part formed of each roller clearance of a series of linearly arranged rolling roller devices. The conveyor is either fixed or elevatably adjustable. Each roller device is driven by one common motor to the rolling part of the next rolling roller device so that a wheat flour band advancing while being rolled, in series, by each rolling roller device may be automatically introduced into the next rolling roller device. The band may be supported in case it becomes loose while being rolled and may be automatically introduced into the rolling part of the next rolling roller device even if it breaks.

Abstract: The present invention teaches an apparatus and method for noodle rolling. The apparatus includes a plurality of roller sets vertically arranged one below the other. Each roller set has roller pairs facing each other. The roller gap of each roller set is shifted laterally with respect to the next lower roller set within a range corresponding to the distance between the pair of rollers in the next lower roller set. In this manner, the noodle strip is first guided by the roller periphery in the next lower set before entering the roller gap therein. The noodle strip formed in the uppermost set is progressively rolled through the succession of the following roller sets.

Abstract: New triazine compositions having incorporated therewithin both alkanolamino groups and pendent tertiary amino groups are defined herein. The triazines are prepared by the reaction of (1) an intermediate prepared from either alkyl chlorides or alkylene oxides and dialkylaminoalkyl primary amines and (2) cyanuric chloride or a derivative thereof. The triazines hereof exhibit excellent catalytic activity in the preparation of rigid cellular foams characterized by carbodiimide linkages.

Abstract: Stable materials, such as films of fluorinated ethylene-propylene copolymers, are bonded to synthetic resinous cell frames with a cyanoacrylate adhesive. The so-covered frames are optimally employed in bipolar electrolytic filter press cells.

Abstract: A ladies' handbag has incorporated therewith a radio or other audio emitting device. A pocket is provided in the interior of the bag in which the audio device is disposed. Suitable apertures are formed through the exterior of the handbag to permit access to the control knobs of the audio device. An exterior protector covers the apertures to prevent damage to the device and to protect it from inclement weather.

Abstract: A cell frame for a bipolar electrolytic filter press cell includes an electrolysis-associated lower section and a gas disengagement or diverting upper section. A pressure bar extends across the cell frame immediately above the lower section to prevent distortion of the separator by cathode generated gases, and to promote disengagement of the gases. The frame, also, includes external headers in the upper section for collection of the gases evolved by the electrolysis of the electrolytic solutions.

Abstract: A ferrous metal cathode used in a chlor-alkali electrolytic cell has a metallic coating deposited thereon. The metallic coating is applied by either flame spraying or plasma spraying a powdered metal onto the ferrous metal surface. The metals which are utilized are those having a lower hydrogen overvoltage than iron.

Abstract: A device for removing kernels of corn from the cob. The cob is rotatably mounted on a shaft and an axially movable blade engages the cob as it rotates to remove the kernels therefrom. A container is provided for collecting the kernels as they are severed from the cob.

Abstract: An anchor for facilitating the suspending of articles from walls or ceilings includes a tubular fastener-receiving member which penetrates the wall. The tubular member has an arcuate free end which causes a fastener, such as a nail inserted therethrough to curl out of and back into the wall. The anchor is particularly useful in suspending articles from dry wall and the like.

Abstract: An apparatus is disclosed for removing fasteners, such as nails and the like. The apparatus includes a pair of pivotally attached levers each having handles at one end, while the opposite ends are provided with support members and claws which, respectively, engage the surface within which the fastener is embedded and the shank of the fastener. Upon the manual application of a force to the handles, the levers coact to apply a separating pressure between the fastener and the material within which the same is embedded to effect an axial withdrawal of the fastener.

Abstract: Apparatus for facilitating the unreeling of wire from cartons or spools thereof includes a vehicle mounted support stand and insertable wire receiving members therefor. A first member includes rotatable legs which seat a carton of wire thereon. A second member receives at least one spool of wire. The support stand is detachably mounted to the vehicle and may be removed therefrom.

Abstract: A model figure representing a horse and rider and consisting basically of two pivotally interconnected parts, each of which is an integral unit, formed, for example, of moulded plastic material. In one embodiment of the invention one of the parts is constituted by the arms of the rider and the majority of the horse, apart from the shoulders and fore legs. The hind legs may be formed integrally with this part or they may be pivotally attached to it. The second part of the model in this embodiment consists of the shoulders of the horse and the whole of the rider, apart from the arms. The fore legs may be formed integrally with this second part or they may be pivotally attached thereto. In a second embodiment of the invention, the first part of the model consists of the body and arms of the rider, together with the majority of the horse, while the other part of the model consists of the rider's legs, together with the shoulders of the horse.
