  • Patent number: 5362443
    Abstract: A method and an apparatus for simply disposing medical waste from a medical institution on site. The method comprises crushing medical waste in a closed container, exhausting air out of the container, sterilizing the air before releasing it into the atmosphere, and filling the container with a high-pressure steam having a temperature between 110.degree. C. and 150.degree. C. to sterilize the crushed medical waste. The apparatus is equipped with a pressure container having at least one air-tight seal, an internal waste crushing mechanism such as blades, an internal supply of steam, a valve for exhausting air from the container, and an air sterilizer for the exhausted air.

  • Patent number: 4726318
    Abstract: Objects molded of synthetic resin such as slide fastener sliders are dyed with a dye liquor having a bath ratio appropriate for an actual amount of dyestuff to be applied to the objects which has been determined from the outer surface area of the objects and the thickness of a dye layer to be formed thereon. The dye liquor is brought into contact with the objects while the dye liquor is being supplied in circulation through a dyeing tank or contained together with the objects in the dyeing tank.

  • Patent number: 4426075
    Abstract: A safety switch for use with a personal exercise machine, of the type having a driven endless belt, permits the drive motor to be shut off immediately by a quick downward thrust by the user of two prominent handles. The extent of travel of the linkage in the switch system is extremely short and the pressure necessary to actuate the safety switch is adjustable. Downward thrust of the handles, by overcoming an adjustable tension spring, frees the switch actuating lever so that the switch is biased to an open position thereby breaking the circuit to the drive motor.

  • Patent number: 4364556
    Abstract: An emergency shut-off switch assembly and a frame assembly for use with a treadmill-type exercise apparatus. The switch assembly includes handles connected to an upper portion of a housing assembly of the exercise apparatus. Independent shut-off switches for substantially instantaneously de-energizing a motor of the apparatus are closely spaced from lower ends of each of the handles in such manner that a downward force greater than a predetermined amount on either of the handles actuates its associated switch. Actuation of the switch results in substantially instantaneous stopping of the belt of the apparatus. The frame assembly includes supports for adjustably connecting ends of an axle of an idler pulley to the frame assembly so that the angular orientation of the axle with respect to the frame assembly is adjustable and pulleys are easily removed or replaced. Also, one end of a driven pulley of the apparatus is adjustably connected to the frame assembly.

  • Patent number: 4316297
    Abstract: A tumbling floor features an assembly of rigid panels beneath each of which is an array of soft foamed blocks of cushioning material which rest upon the gymnasium floor. The panels are covered by foamed panels of soft springing material and the latter in turn covered by a thin carpet providing a non-slip surface.

  • Patent number: 4245838
    Abstract: An improved above ground landing pit particularly suitable for pole vaulting events is disclosed wherein the frontal portion of the pit includes an opening which surrounds the plant box having an angularly inclined back wall to accommodate the substantial flexure of the vaulting pole during the vault. The sidewalls of the pit are additionally provided with a tapered recess adjacent the lower edge thereof which permits the upper portion of each sidewall to extend in a cantilevered manner over the respective post standard thereby preventing injury to the athlete. Further, the present invention discloses a unique post standard which is exclusively anchored in position by the weight of the pit yet permits the post to be selectively positioned relative the length of the pit.

  • Patent number: 4162063
    Abstract: The typical helical springs used to support the bed within the frame of a trampoline or the like are modified to incorporate adjustable hooks threadedly anchored within the springs at one end so that their overall length, and thus the tension on the bed, can be varied and overstretching accommodated. Two principal versions are disclosed, the more preferred one including an additional inner spring biasing the adjustable hook to a retracted position.

  • Patent number: 4045021
    Abstract: A form of trampoline apparatus for use in connection with tumbling and the like employs a relatively long-narrow bed resiliently suspended between a pair of side rails only so that the two opposite ends of the bed are unobstructed by any cross rails or other structure. The two rails are supported above the floor by a substructure which interconnects them and holds the rails apart against the tension of the bed. One end of the bed inclines upwardly toward the remainder of the bed which is horizontal with respect to the floor. The trampoline is narrower relative to its length and having dimensions such that the length is substantially three times or more its width to provide directional rebound characteristics.

  • Patent number: 4008892
    Abstract: A runner traverses a long distance by running back and forth over a short pathway or lane laid out on a floor and at each end of the lane reverses his direction by partially turning just before striking one of a pair of resilient backstops, each pair having an inverted U-shaped frame, placed at the ends of the lane. In other cases a backstop may be used at one end only of the lane, the runner thus traversing the lane only twice. Each backstop, due to its angle with the floor, rebounds the runner back in the opposite direction at substantially the same speed at which he struck the backstop. In these manners and with such apparatus not only can longer distances be effectively run over relatively short lengths of gymnasium floor, for instance, but various types of foot races can also be conducted indoors.

  • Patent number: 3938792
    Abstract: The hooked ends of the springs or like members by which the bed of a trampoline or similar apparatus is suspended from its frame are equipped with protective sleeves of flexible material. The sleeves are split at their outer ends to form two flaps, one of which covers the exposed ends of the hooks to prevent injury to a performer inadvertently striking them, while the two flaps together are foldable back onto the sleeve to assist hooking and unhooking of the springs to and from the bed and the frame.
