Abstract: ABSTRACT OF THE DISCLOSURE        A dispenser device is described having a metering chamber provided with inlet and outlet ports.  Independently mounted, angularly disposed valves are associated with the ports.  Actuator means comprising a cam wheel driven by an electric motor operates the valves in predetermined sequence through valve control arms respectively associated with each of the valves.  The valve control arms are pivotally mounted and co-operate with an extension of the valve stem extending externally of the metering chamber.          The electric motor is actuated by a button operating through a lever so as to close a switch.  The cam wheel includes a switch cam track which holds the switch closed for a full cycle of the dispenser.  Also a deactivating cam track is arranged to displace the lever so that manipulation of the button cannot effect the dispenser operation once the cycle has been initiated.

Abstract: Abstract A continuous tube T is formed by spirally-winding an extruded thermoplastic ribbon R having mating edges which are joined together to form a spiral seam and having at least one reinforcing rib 3 which, when in its spiral wrapped form projects radially out from the tube. At predetermined lengths, the tube is cut and at the same time the outer surfaces of the tube on each side of the cut are shaped to facilitate handling and interconnecting of pipe section 1 thus formed. At least one end of the pipe has an annular groove 6 at a uniform distance from that end. This groove is formed by cutting a path through each of the radially extending reinforcing ribs intersecting its annular path. An elastomeric O-ring 8 engages the outer surface of the pipe and the axial movement of the O-ring is restrained ribs. walls of the groove formed by the radially extending reinforcing ribs. An apparatus 30 for cutting the tube at predetermined lengths into pipe sections while the tube is proceeding out of the spirally-winding operation also imparts to the outer surfaces the desired shape as well as cuts the groove for the elastomeric O-ring. This apparatus performs this cutting and shaping operation without interrupting the continuous forming of the tube from the spirally-wound thermoplastic ribbon.

Abstract: Abstract Elongate articles of non-circular cross section such as those of an airfoil cross section are constructed by winding filamentary material in layers about a  form between a pair of spaced turnarounds generally conforming in shape to the cross sectional shape of the form.  Adjacent layers are continuously wound by winding the filamentary material across the edges and outer face of each turnaround while reversing the direction of relative longitudinal displace-ment between the filamentary material and the form.  The shape correspondence between the turnarounds and the form effect a minimization of expanse between the turnaround edge and form surface, thereby minimizing bridging of the filamentary material between those two members.

Abstract: ABSTRACT The invention relates to apparatus for analyzing electrical circuit boards.  Individual elements which have failed can be identified without disconnecting them from the circuit and testing may be done by unskilled operators by contacting a probe to a lead on an element.  The probe has at least two contact elements close enough to each other to simultaneously con-tact a lead of a mounted integrated circuit, but spaced apart from each other sufficiently to permit measurement of electrical activity in the lead segment between the tips.  Circuitry is connected to the probe for measuring the voltage drop between the two tips resulting from the flow of test current through the resistance of the lead segment, which current flow is indicative of the condition of the element.

Abstract: A Wall Construction for a Vehicle Cab Abstract In construction vehicles it is not uncommon to have the cab or operator's station positioned directly adjacent the engine enclosure.  Being so positioned, the transfer of the heat created by the engine is often transferred directly into the confines of the cab by a wall of the cab.  The wall construction of this invention includes an air passage in which a current of ambient air is established within the wall.  A pressure drop, which is created by an existing flowage of air within the engine enclosure, is utilized to pull ambient air from the cab interior and through the air passage.  The air moving through the passage provides a cooling thereof to prevent the transfer of heat from the engine enclosure to the cab interior.
