  • Patent number: 5031237
    Abstract: The present invention comprises apparatus and methods of using a light sensitive switch, such as a photo-electric or photo-resistive cell, to actuate a battery powered electric motor which rotates a fan blade located within a housing near a facial area of a welding helmet. When exposed to a high intensity light, such as the light emitted during a welding process, the photoconductive cell actuates the battery powered motor. When activated, the motor rotates the fan blade which draws air away from the face of a wearer and passes such air through a filter into an air flow chamber, thereby, filtering the drawn air. The rotation of the fan blade then forces the filtered air toward the facial area of the wearer. A smoke block, which restricts the entrance of smoke or other contaminated vapors from entering the confines between the interior surface of the helmet and the face of the wearer, may be removably attached to the helmet.

  • Patent number: 5031255
    Abstract: A whirlpool home appliance is built into a U-shaped housing for fitting over and clamping to the side of a bath tub. A water pump is in the side of the housing which is in the bath tub in order to energize the water in the tub. An air pump is in the side of the housing which is outside the tub in order to pump air to a bubbling bath mat which fits on the bottom of a bath tub. The motor for the appliance is a reversing motor which runs in either of two directions. A one-way clutch disconnects the water pump when the bubbling air mat is used. The air pump may run all of the time since the loading of an air pump is not so great that it must be disconnected when not in use. The housing is attached to the tub by a screw which has a large area of relatively soft padding with a radially distributed flexibility so that there is no abrupt discontinuity of clamping forces. The pad avoids and prevents damage to a plastic or fiber glass bath tub when the screw tightened.

  • Patent number: 5031270
    Abstract: A hinge for a self-closing door includes a pair of hinge leaves having their respective knuckles joined to a hinge pin, one of the hinge leaves being fixed to the hinge pin and the other rotatable with respect to the same. A torsion spring is wound when the door to which the hinge is attached is opened. The torsion spring exerts a returning force which tends to keep the door in a closed position. Friction means is employed to arrest the closing of the door to prevent slamming. The friction means includes a first and second set of alternately interleaved friction plates, one set of which rotates while the other remains fixed when the door is allowed to close. The rubbing of the friction plates generates a retarding force which arrests the closing of the door. An adjusting member is also added to vary the amount of friction between the friction plates with the degree of opening of the door.

  • Patent number: 5031273
    Abstract: The vibration-free handle comprises a first rod connected to a vibration source via an attachment, a second rod connected to the first rod at one end thereof with a predetermined inclination, a mass body mounted on the other end of the second rod, and an elastic member provided between the first rod and the vibration source for covering the first and second rods. The elastic member possesses spring constants in three directions, one direction being defined by the direction the vibration source vibrates (z-direction) and the other two directions extending perpendicularly to each other in a plane perpendicular to the z-direction. When the second rod, which serves as a grip of the handle, extends perpendicularly to the z-direction and the vibration source starts vibrating, there appear "vibration knots" in the second rod, at which the vibration amplitude is substantially zero, in three directions. The "vibration knots" reduce the vibration from the vibration source.

  • Patent number: 5031275
    Abstract: A hinge is described having a first plate consisting of two leaves which form at their end portions a barrel and an awl member received within the barrel. A second plate is then mounted on the awl member so that the second plate is contained within a plane which is parallel to the plane containing the longitudinal axis of the awl member. The diameter of the awl member is slightly larger than the diameter of the barrel and when the plates are mounted with screws, the diameter of the barrel will be further restricted so that friction will control operation of the hinge.

  • Patent number: 5031277
    Abstract: An improved trash and leaf bagging apparatus is constructed of a rigid frame having an opening that is completely surrounded with a supply of netting material that forms a netting bag. The rigid frame may be connected to a handle, to facilitate mobility; the rigid frame may also be connected to a collapsible tunnel assembly that forms a converging tunnel toward the frame opening. Trash, leaves or other refuse is projected through the rigid frame and into the netting bag by means of an air blowing device. When the bag is filled to the desired capacity, the netting material is cut and tied at the open end to form a completely enclosed bag of refuse. A new netting bag may be formed from the supply of netting surrounding the rigid frame and the process repeated.

  • Patent number: 5031278
    Abstract: A card including a main cylinder, a revolving flat as well as a licker-in roller and a doffing roller (also called a doffer roll) also includes a suction device in combination with a separating knife in order to improve the carding result and eliminate dirt in the precarding zone between the licker-in and the revolving flat, in the after carding zone between the revolving flat and the doffer roll as well as in the precarding zone between the doffer roll and the licker-in. A preparatory element has a structured surface arranged opposite to the surface of the main cylinder, in which the teeth are arranged facing the direction of rotation of the main cylinder. This structured surface allows the carding result to be retained and subjects the fleece lying on the main cylinder to a certain vibration so that, in combination with centrifugal force and the separating knife, there is better dirt separation which can be removed through the suction device.
