Abstract: A mount for a tilting inversion exercise table includes a stand composed of spaced A-frames having spaced trunnion-supporting bearing plates with blind bearing slots receiving trunnions in such slots, and swingable keeper arms pivoted on the trunnion-supporting bearing plates and having hooked ends swingable into positions blocking escape of the trunnions from the bearing slots. Helical tension springs connected between the trunnion-supporting bearing plates and the keeper arms urge the arms into positions in which their hooked ends block escape of the trunnions from the blind bearing slots.

Abstract: A flat blank of circular segmental shape having a recessed chord and made of thermoplastic material is heated in a bath of hot water in the range of 145 degrees F. (63 degrees C.) and 160 degrees F. (71 degrees C.) to render the material soft and supple. The blank is then manipulated and pressed in applying it to a dental arch for forming a facing alongside the oral cavity into which a throat insert is to be inserted for protecting the teeth of the arch from being injured, such as by being cracked or chipped, by impact with the teeth of such a throat insert or its appendages.

Abstract: Continued bleeding into a pocket or hematoma in the cranium could exert pressure on the brain which would move it relative to the cranium to force the brain stem into the medulla oblongata to arrest breathing. Such brain micromovement is detected by projecting bursts of ultrasound into one or both of the temple areas of the cranium or into the medulla oblongata, and the readout of echoes received from different depths is displayed on a screen. The readout of the echoes indicates continued microshifts of the brain relative to the cranium. To differentiate microshifts of the brain relative to the cranium caused by continued intracranial bleeding as distinguished from pulsations of the brain relative to the cranium caused by supply of blood to the brain from the heart and return of blood from the brain to the heart, the timing of the bursts of ultrasound into the cranium is synchronized with the pulse indicated by a heart pulse monitor.

Abstract: Malodorous substances resulting from the decomposition of organic products derived from living organisms, such as acrolein, ammonia, aldehydes, cadaverine, indole, alkaloids including primary and/or secondary amines, butyric acid and skatole, separately or in combination, which may be included in polluted air escaping from rendering plants or cooks, poultry and seafood processing plants, food canneries, tanneries, sewage treatment plants or excrement receptacles, or which may be carried by or impregnated in fabrics, can be rendered unobjectionable by treatment of such air, facilities or products with metallic material including inorganic metal salts such as chlorides, sulfates, nitrates and phosphates, oxides and hydroxides. Suitable metals include aluminum, copper, iron, nickel and zinc. Usually the metallic material is carried by or contained in a liquid vehicle, but in some instances may be used in powder form.

Abstract: Apparatus for tracking the motion of subcutaneous body parts such as tendons in the carpal tunnel of the wrist by use of an ultrasonic sensor, and supplying signals from such sensor to a computer for comparison with reference data in a memory and utilizing the output of the computer to drive a readout such as a visual display or printing of text corresponding to motions of the subcutaneous body parts such as tendons in the carpal tunnel effected by movement of the fingers as in simulated typing. Alternatively, the movement of other subcutaneous body parts such as facial muscles can be sensed, and signals generated from the sensor can be transmitted to a computer for processing to actuate or control apparatus such as an artificial limb or a motorized wheelchair.

Abstract: Endless loops spaced lengthwise of elongated grouser-mounting plates of a tractor endless tread in which each loop includes two side-by-side stretches of wire rope having the interstices between the strands of both wire rope stretches filled with elastomer material, and both stretches of wire rope being embedded in elastomer material integrating the two stretches into a single embedment, the two wire rope loops being secured to the grouser-mounting plates by spaced U-shaped bends of clamping strips bolted to the grouser-mounting plates, and spacer plates bridge between adjacent grouser-mounting plates and make loose tongue-and-groove joints therewith for enabling the grouser-mounting plates and the spacer plates to tilt relatively as the endless tread travels around a tractor wheel, but the straight tread portion of the tread extending between tractor wheels spaced lengthwise of the tractor is substantially inflexible inward.

Abstract: A refuse-collecting drainpipe insert is a generally helical coil formed by a strip of rectangular cross section and having a bulge located axially generally centrally of the coil, and frustoconical end portions tapered oppositely from the central bulge of the coil, the strip at one end of the coil being formed as a hook and the strip at the other end of the coil being formed as a return bend.

Abstract: In a fabricated door jamb, the opposite edges of a rib component core of low-grade lumber are faced with strips of high-grade wood, and the face is veneered. Two flange components are fabricated from cores of low-grade lumber, each having one edge finished with a strip of high-grade wood, and their faces are veneered. The flange components are joined to the generally central edge component by tongue-and-groove joints composed of tongues formed on the adjacent edges of the flange components which fit snugly in the grooves in opposite edges of the tongue component, respectively. Each groove is flared and each tongue is tapered complementally so that the tongues fit snugly and wedgingly in the grooves, the tongue-and-groove joints being located so that the backs of the tongue component and of the two flange components are flush and coplanar.

Abstract: The valve in automatic shutoff valve mechanism is held in a predetermined elevated open position by a magnet spaced above the valve, and the valve can be released for downward movement into shutoff position either by melting of a fusible nut holding a threaded magnet-supporting stem or by the mechanism being vibrated sufficiently severely to shake the valve loose from the attraction of the magnet.

Abstract: The anchor shoes of a tunnel-boring machine arranged in a circular configuration are individually truncated by being tapered rearwardly so that the girth of the circular anchor shoe configuration can decrease progressively in order to accommodate convergence of superincumbent ground pressure. Preferably the anchor shoes are mounted for tilting of their aft portions to enable the degree of convergence or constriction to be altered. Chordal jacks connecting adjacent anchor shoes exert pressure on them resisting inward swinging of the aft portions of the anchor shoes resulting from superincumbent ground pressure.

Abstract: A prefabricated conservatory enclosure for a waste recycling center to be attached to a building includes an upper bay window recess having a bottom counter and a lower housing for enclosing one or more receptacles for recyclable material, the counter having openings for deposit of waste into the receptacles from the upper recess, and the lower portion of the enclosure having an integrating wall fitted with plumbing for a kitchen sink and adapted to be integrated with the structure of a building to which the enclosure is annexed.

Abstract: The head of a fish is severed from the fish body in a two-stage operation, in the first stage the root of the fish head beneath the gill covers being cut partway through and in the second stage the severance of the fish head from the fish body being completed. The first stage cutting operation is effected by cooperating disk cutters converging toward the fish head at an acute angle, means for sensing the thickness of a fish, and means for adjusting the spacing of the disk cutters in accordance with the thickness of the fish sensed. The fish are transported unidirectionally, and the spacing of the cutting disks is adjusted while the cutters are being reciprocated in the same direction of the travel as the fish is transported, and the disk cutters are then reciprocated in the direction opposite the direction of transport of the fish to effect the first stage cutting operation.

Abstract: A sample of slurry is withdrawn continuously from a pressure pipe through which the slurry flows by a diluting sample-extractor mounted on the pipe. Dilution water is added continuously to the extractor to mix with the withdrawn sample to provide dilute slurry, and the quality of the dilute slurry is evaluated by passing it through a viewing window chamber and taking periodic photographs of the dilute slurry passing through such viewing window chamber.

Abstract: A golf clubhead includes a lower part with stepped ramps spaced apart and inclined downwardly toward each other engageable by stepped undersurface slopes at the opposite ends of an upper clubhead part carried by the golf club shank, which lower part and upper part can be secured together in different tilted relationships to alter the lie of the golf club. The upper clubhead part has two generally horizontal weight-receiving bores located at opposite sides, respectively, of the longitudinal center of such part and equally spaced from such center, and the clubhead lower part has upright weight-receiving bores located at opposite sides, respectively, of the longitudinal center of such part and equally spaced from such center for receiving weight slugs selectively to alter the weight and balance of the clubhead. The two parts are inserted in a shell having opposite faces forming blades having different lofts.

Abstract: The upper end portions of splayed legs are connected by pins that slide lengthwise of slots extending transversely of a crosspiece, the opposite ends of which can be supported by pairs of splayed legs, respectively. Sliding of the pins in their slots enables the ends of the legs to be fitted into sockets in the crosspiece and enables the legs to be withdrawn lengthwise from the crosspiece sockets, then swung together in substantial parallelism, and finally swung about the axis of the pins into overlapping folded relationship nested in angles of the crosspiece which is of T-bar cross section. Tubular extensions can be provided for the legs, and steps connecting the legs at opposite ends of the crosspiece can be attached for enabling a worker to step up onto the crosspiece.

Abstract: A log chipper is provided for allowing a lower horsepower rated motor to drive the chipper. Peak power demand is reduced by cutting shorter chips from large diameter logs, while the length of chips cut from logs of small and medium diameter continues to be of standard specified length, the length of chips cut from large diameter logs only being shortened. The feed rate for large diameter logs is reduced and will therefore result in a reduction of peak power demand achieved by the use of large diameter log positioning means. A first version of the large diameter log positioning means involves the placement of a raised platform on the wear plate where the outer perimeter of the large diameter log would otherwise contact the wear plate. A second version of the positioning means involves raising the heel of the knife clamp at a point where a portion of the outer perimeter of a large diameter log contacts the heel of the clamp.
