Abstract: A system for providing digital data representative of a selected analog signal on the data lines of a programmable controller using a central processing unit. The system employs a conversion circuit which converts the input analog signal to digital data on output data terminals upon receipt of a conversion signal simultaneously with an analog signal and which creates a completion signal when the conversion is completed. The system can use at least two analog inputs that receive at least two analog conditions and convert a selected one of the analog conditions to an analog signal. Upon actuation of one of the input modules, the selected analog signal of the selected module is directed to the conversion circuit. After conversion, the conversion completion signal of a conversion circuit then deactivates the actuated input module for the next conversion cycle.

Abstract: An improvement in a device for plating a thin layer of a first metal onto the surface of a generally flat metal strip formed of a second metal as the strip is moving in a selected direction along a given path, wherein the device includes an anode in the chamber and means for supplying electrolyte containing ions of the first metal between the anode and the moving strip. The improvement involves providing the anode as an electrically conductive, non-consumable, anode element having an outer surface with a transverse width substantially as great as the width of the strip. A plenum chamber is formed behind the anode element and generally coextensive with the outer surface of the element so that apertures in the anode element direct jets of electrolyte through the anode element and directly against the surface being plated to provide a uniformly turbulent flow of electrolyte at the surface of the strip.

Abstract: An electric radial blade type heating element is provided for industrial furnaces or other heated devices in which the electrical conductors are relatively thin flat strips or blades, rectangular in cross section and free floating relative to the insulating support structure of the element. The conductors are arrayed in a radially diverging relationship to maximize the exposure of the radiating surfaces which minimizes the pocketing of released heat and overheating of the elements. Means are provided to pass a fluid over the conductors when the element is mounted within a radiant tube to reduce oxidation of the element and the interior surface of the radiant tube. The heating element support structure is not dependent on the conductors for strength or rigidity, thereby rendering the element equally suitable for vertical as well as horizontal installation. The element may be used to directly heat a furnace, or may be mounted in a radiant tube to heat the radiant tube.

Abstract: A fluid pressure shock absorbing valve is mounted between an oxygen supply tank and a fluid pressure regulator in a supply system such as that for welding torches. The valve includes a housing slidably supporting a valve member having a head biased to seat in the direction of flow from the tank to the regulator to normally close the valve. The valve member has a central flow passageway extending thereinto from the downstream end, and a restricted passageway extends through the head and opens into the flow passageway to bleed fluid through the head when the latter engages the seat. Radially extending passageways open into the flow passageway downstream from the seat. When the supply tank is opened, flow through the restricted passageway allows for gradual pressurization of the regulator and an eventual build-up of pressure to displace the valve member from the seat to allow full flow past the seat and into the flow passageway through the radial passages.

Abstract: A mounting for a radio antenna which enables the antenna to be easily mounted on and demounted from the edge of the trunk lid of an automobile without marring the surface. The mount consists of a flat base member and a clamping member pivoted relative to the base in the plane thereof and having a lip spaced from the base. A clamping pad is mounted on the base for movement toward and away from the lip by means of a screw threaded in the base. The members are pivoted so that the lip is exposed and may be easily inserted into the space between the edge of the trunk lid and the body of the automobile without interference from the base. The base is then pivoted relative to the clamping member so as to be opposite the lip and the clamping pad is pushed against the outside of the trunk lid.

Abstract: An improved delay primer unit for detonating an explosive material in a borehole with a detonating cord down line extending into the borehole. The primer comprises an explosive element capable of detonating the explosive material upon being detonated, means for preventing direct detonation of the explosive element by the down line, a time delay detonating element extending between the down line and the explosive element with a known detonation time delay value between first and second ends of the delay element, means slidably associating the first end with the down line and means for connecting the second end in detonation relationship with the explosive element. The improvement in this type of unit is the provision of the explosive element as a support element and a detonating cord wrapped around the support element to form a primer.

Abstract: In a spreader of the type used for spreading particulate material onto a roadway and comprising an upper hopper having a lower material discharge chamber terminating in a lower discharge opening, a rotatable spreader element below the discharge opening and a valve mechanism between the discharge chamber and the spreader element for controlling flow of material from the chamber to the spreader, there is provided an arrangement for shifting the valve mechanism between an opened and closed position in response to the direction of rotation of the spreader element. When the spreader element is rotating in one direction, the valve mechanism is automatically opened. When the spreader is rotated in the opposite direction the valve mechanism is automatically closed. This valve operating feature is accomplished by transmitting force through the particulate material within the discharge chamber of the spreader device so that no physical connection is provided between the motor and the valve shifting arrangement.
