Abstract: A sampling device for sampling the output of compressed gas sources, such as air compressors, for solid contaminants, such as debris and oil mist, and for gaseous contaminants, such as carbon monoxide and for obtaining filter samples and plenum samples for laboratory analysis generally comprises a manifold including a first conduit and a second conduit, a filter device, a safety valve, a sampling bomb, a flow director valve, and a pressure control valve. The first conduit has a gas receiving end and a filter device end. The second conduit has an inlet end connected to the first conduit and a vent end. A flow director valve at the junction of the first and second conduits is operable from a full shunt position wherein all incoming gas is directed into the second conduit and a full open position wherein incoming gas is directed to the filter or the second conduit. A pressure control valve disposed in the second conduit near the vent end controls the exit of gas out the vent.

Abstract: A foldable sandwich bag includes a wall of laminated structure having an inner layer of waterproof, thin, easily tearable material, such as aluminum foil, and an outer wrap securely attached thereto to form a laminate. The outer layer is made of thicker, stronger, tear-resistant material, such as vinyl tape, and is configured in segments that can be torn away along with the attached inner layer to reveal the contents of the bag. The bag can be laminated in a flat configuration and formed into a bag with overlapping vertical seam and having a vertical separation between segments.

Abstract: An emergency shut-off for a flush tank having a liquid replenishment valve is connected to the liquid replenishment valve for moving the valve to a closed position if liquid level in the tank has not reached a predetermined height within a predetermined time after the tank has been flushed. Broadly speaking, the emergency shut-off comprises a container, a buoy, and a valve connection mechanism. The container extends downward in the tank from at least the predetermined height and includes a valve for allowing liquid in the tank to enter the container and for allowing liquid within the container to egress into the tank at a predetermined rate. The buoy in the container raises and lowers with the liquid level in the container and contacts the valve connection mechanism when the liquid in the container is at a predetermined shut-off height. The valve connection mechanism is connected to the valve for closing the valve in response to contact by the buoy.

Abstract: A device for injecting a liquid repair material into a crack in glass such as a windshield has a central body portion including a rigid frame that is supported by three legs in a triangular configuration. A suction cup with a single adjustment knob holds the device against the windshield. One of the legs is an injector assembly comprising a cylinder and pressure screw assembly. Vacuum is applied to the cylinder by a nipple through the cylinder sidewall. An O-ring at the bottom of the cylinder sidewall seals between the bottom of the cylinder sidewall and the windshield. The pressure screw assembly includes a piston slidable within the internal passage. The lower end of the piston includes a seal for sealing engagement with the sidewall. In the preferred embodiment the piston seal is a sealing cap completely covering the bottom end of the piston and completely blocking the passage and sealing against said sidewall.

Abstract: An anchoring bracket for use in attaching substantially parallel boards to a generally transverse member or joist and in spacing the boards generally comprises a rain-spacer side and a joist attachment side. The rain spacer side has a spacing portion for placement on the top of the joist for spacing a board from the joist and an extended portion attached to the spacing portion for extending over the edge of the joist. A board spacer tab, affixed to the rain-spacer side, projects generally perpendicularly upward therefrom for positioning directly adjacent a board for controlling the spacing thereof. The joist attachment side includes an attachment portion disposed generally perpendicular to the rain-spacer side for attachment to the side of the joist and an angled portion connecting the attachment portion to the outer end of the extended portion. The angled portion includes holes for receiving a fastener for fastening a board to the bracket.

Abstract: An attachment for the pull tab of a slide fastener for enhancing manipulation of the slider and for serving as an ornamental and identifying element generally comprises a clip of very hard and stiff, yet resilient, material, such as spring steel, molded into a body of soft, tactile, elastomeric material. A channel leading to the clip in the body receives the pull tab. The elastic side walls of the channel expand to accommodate pull tabs of varying sizes and stabilize the attachment on the tab. The clip has a locking tongue which projects into the channel in a direction away from the channel entrance and terminates in an engaging end for engaging and locking the tab in the channel. The engaging end is curved such that considerable pressure is exerted by its point onto the tab surface. Body material directly overlies the tongue such that deflection of the tongue also compresses and deflects the body material.

Abstract: A slalom ski includes bindings for retaining a skier's feet in an overlapping tandum disposition. A rear foot binding for retaining the skier's rear foot includes a vamp. The front foot binding for retaining a skier's front foot includes a vamp and a heel member. The heel member supports the skier's front foot heel above the rear foot vamp and restrains it from rearward and upward movement. In the preferred embodiment, the position of the bindings fore and aft on the ski is adjustable. Also, the relative position of the vamps and heel pieces are adjustable.

Abstract: A cable shield to connector back shell termination device includes a back shell of a multi-pin cable connector, a plurality of metallic tubes adapted to receive individually the end of a shielded cable such that substantially full circumferential conductive contact is maintained between each cable shield and a tube, and a cluster of such tubes conductively bonded together and shaped to fit the back shell for conductive bonding to the back shell. A second embodiment employs a conductive sleeve for conductive mounting on the cable shield. Ridges or fins extending generally lengthwise on the sleeve frictionally, conductively contact the metal tubes. In this manner an uninterrupted conductive surface is maintained at the connector. The connector enclosure thus provides a shield against the intrusion of electromagnetic energy in the environment in which the electrical or electronic wiring and circuits must operate.

Abstract: A highly accurate rapid gimbal assembly method utilizes two fixtures for establishing the critical gimbal assembly parameters of yield and axis of intersection and an adhesive for bonding each mating surface of the gimbal assembly for holding the components of the gimbal assembly in their adjusted positions. The fixtures include an inner/outer gimbal fixture for holding the inner and outer gimbals in relative position for bonding and a gimbal/post fixture for holding the gimbal assembly in alignment on the support post for bonding. These fixtures and assembly method eliminate the need for use of shims between the mating surfaces for establishing alignment of the critical parameters.

Abstract: A dielectric heat sensor system for monitoring and measuring the effects of electromagnetic radiation on the performance or physical integrity of an electrical or electronic component includes a dielectric receiver in the form of a rectilinear array of fiber optic ends positioned to receive infrared heat waves from a bridgewire of an electro-explosive device and transmitting the infrared heat waves by way of a waveguide of electro optic fibers to an infrared detecting unit which is effective to activate an indicator.
