Abstract: A method and apparatus for controlling combustion in a process heater provides for efficient control of the combustion with a minimum of components. The apparatus includes means for generating a signal from a condition of a process such as temperature, or pressure in the case of a boiler. In one embodiment the milliampere signal is presented in series to a resistor to provide an instant proportional voltage signal. This instant voltage signal is then fed into an R-C network to provide a ramp voltage signal. These two voltages are fed into voltage comparator switches which direct the instant voltage signal and the ramp voltage signal to one of two output amplifiers. The output amplifiers control the output signal to the external control devices. The external control devices adjust the flow of fuel and combustion air. The outputs are controlled so as to always provide a fuel-lean mixture during a change in the operating conditions of the process.

Abstract: A device for stabilizing, with reference to the surrounding terrain, a cable splice enclosure having a cable splice therein, comprising a stabilizer rail positionable in a supporting position adjacent the splice enclosure, strap means for holding the splice enclosure in position against the stabilizer rail, a spacer member adjustably positionable longitudinally on the stabilizer rail for supporting a portion of cable near the splice enclosure, a cradle member adjustably positionable longitudinally on the stabilizer rail and supporting the splice enclosure, and a support leg attachable to the stabilizer rail to extend laterally from the stabilizer rail.

Abstract: A method and apparatus for controlling combustion in a process heater provides for efficient control of the combustion with a minimum of components. The apparatus includes means for generating a signal from a condition of a process, such as temperature, or pressure in the case of a boiler. The signal, which may be a pressure signal, is presented in parallel to a needle valve, to a first fluid-responsive relay, and to a second fluid-responsive relay. A volume tank is connected in series to the needle valve and in parallel to the first relay and to the second relay. The first relay communicates with means for controlling the flow of combustion air. The second relay communicates with means for controlling the flow of fuel. When the signal of the process condition is below the point at which a controller is set, then the signal is an increasing pressure signal. When the signal of the process condition is above the point at which the controller is set, then the signal is a decreasing pressure signal.

Abstract: A fishing rig holder comprises three panel members foldably connected with ends of the first and third panels connected to the second panel. In folding, the second and third panels swing down and around the first panel. In a folded condition, the panels are stacked planarly with the first panel in the center, covered on one side by the second panel and on the other side by the third panel. The first and third panels include spring-actuated members for holding taut a fishing line, especially taut when the panels are folded in position because the fishing line is on the exterior of the folded panels. Alternate means are provided for maintaining the panels in a planar position when unfolded because otherwise the tension of the line tends to cause the panels to collapse. One of these means is provided by a locking position incorporated into the hinges connecting adjoining panels whereby the panels are locked into position when their ends are abutting.

Abstract: A pollution control system comprises method and apparatus for removing particulate and gaseous pollutants from combustion products. The method includes a series of physical and chemical treatments for combustion products. In one embodiment these steps are: passing combustion products through a screen to filter out large particles; washing combustion products with steam; passing combustion products through activated carbon; washing combustion products with a solution of potassium aluminum sulfate, aluminum sulfate, aluminum hydroxide, chlorine, and quicklime; washing combustion products with an aqueous solution of kerosene and naphthalene; and washing combustion products with a solution of aluminum hydroxide, aluminum sulfate, chlorine, quicklime, and sodium carbonate.

Abstract: A portable bathing device comprises a body compartment having four sides and a bottom and having an open top. The body compartment includes a built-in seat, and has an L-shaped door in one side adjacent the seat with the wider port of the door at the top so that when the door is open, the L-shaped opening conforms substantially to the contour of the seat to permit easy, convenient, and safe access to the body compartment for an incapacitated person. The door is removably hinged to the body compartment, and sealing means are provided between the door edges and the body compartment to form a seal when the door is closed tightly in place. A supply water inlet is located in the wall of the body compartment below the seat with this water inlet communicating with flexible hose means attachable to a source of water supply. A shower hose with spray head at the end is connected to the hose means.

Abstract: A method of preheating combustion air being supplied to a furnace, and a furnace including the means for preheating the combustion air. The method comprises circulating a portion of fluid from a fluid stream first in non-contact heat exchange relationship with the flue gas for heat collection, then circulating this portion of fluid in non-contact heat exchange relationship with the combustion air for heat donation thereto. The rate of circulation and temperature of the portion of fluid is controllable substantially independently of the rate of flow and temperature of the parent fluid stream. The furnace comprises means to heat a portion of a fluid stream and includes means to circulate, at a controllable rate and temperature, such portion of fluid from a fluid stream through an adjunct loop connected to the fluid stream for collection of heat from the flue gases and donation of heat to the combustion air.

Abstract: Apparatus for the prevention of theft of electrical appliances comprises an automatic electronic lock off system which may be activated in a particular manner after the appliance is connected to a source of electrical power, and which becomes deactivated when the appliance is disconnected from its source of power to cause the further disconnection in the appliance electrical circuit. The apparatus comprises essentially three components, a key-operated activator switch, a relay, and the appliance's own on-off switch, all connected with the appliance's own circuit leads in a particular manner. The key-operated activator switch is designed to be operated with its own individual key and may, if desired, be hid from view. Initially, the key-operated activator switch is briefly closed to complete a circuit with the coil of the relay. Activation of the relay closes a normally open switch in series with the appliance on-off switch to permit the appliance then to be operable.

Abstract: A fishing lure is formed of a body and a bill attached at the forward end of the body. The bill includes a major portion adjacent the body and inclined downwardly in relation to the longitudinal axis of the body. The major portion terminates forwardly in a minor portion further inclined downwardly in relation to the major portion. Hook means are carried by the body, and a skid arcuately connects a lower portion of the body and the minor portion or leading edge of the bill to facilitate movement of the lure over obstacles.
