Abstract: A heat transfer apparatus having a heat collector on one side of a wall and such collector contains an expandable fluid medium which communicates with a heat dissipating member and causes such member to be extended through the wall to transfer the heat to a location remote from the heat source.

Abstract: A fishing rod holder apparatus including a pair of members mounted on the gunwale of a boat and adapted to support a fishing rod in a position such that the rod extends outwardly of the boat.

Abstract: A rotary cutting apparatus having cutters or knife devices which are provided with angularly disposed contact surfaces and which devices are mounted with the contact surfaces in cooperative engagement with angularly disposed supporting or clamping surfaces of opposed knife support members.

Abstract: A barrier pressure container apparatus for dispensing viscous materials and a method of filling such container. The apparatus includes a generally cylindrical container having concave ends with a piston located between the same and having a viscous material on one side of the piston and fluid under pressure on the opposite side thereof. A dispensing valve is mounted in the top of the container so that material is dispensed by the pressure below the piston when the valve is open.

Abstract: A ripper tool apparatus detachably mounted on a conventional excavator bucket so as to distribute the stresses developed as the implement is used. The apparatus includes a central ripper tooth to break hardened or dense earthen material and a pair of side wall cutter teeth to clean the excavated trench walls.

Abstract: A high analysis fertilizer formulation of a low bulk density powdered ureaform having soluble and insoluble components combined with soluble monopotassium phosphate in which the resultant mixture is a dry homogeneous blend which is free of fillers and binding agents and may be carried in liquid for application to surface or subsurface areas by conventional liquid fertilizer applying equipment.

Abstract: A method for modifying the physical characteristics of cellulose materials by the impregnation of the cellulose fibers with acidic solutions of monomer and oligomeric silicic acid to form a capillary cellulose-polysilicic acid structure to which selective binder materials may be adhered.

Abstract: A sheet metal nail of the type used to fasten a first or covering material to a lightweight base material in which a pair of interfitted channel shaped leg or shank members are pivotally connected to the nail head in a manner to spread outwardly into the base material when the nail is driven therein. The penetrating ends of the shank members are tapered to form cutting edges so that as the nail is driven, the penetrating ends of the shank members cut through the first material without tearing such material.

Abstract: Apparatus for removably mounting a communications antenna on a vehicle in such a manner that the antenna is fully exposed when the vehicle is in use but may be removed and stored out of sight when the vehicle is not in use.

Abstract: A refrigerant delivery and separation apparatus and a process for delivering refrigerant at evaporator temperature to an evaporator at a predetermined pressure which is less than the pressure at the receiver, and simultaneously separating refrigerant liquid and vapor which is discharged from the evaporator. The apparatus includes a pair of tanks connected by time operated control members to conventional refrigeration equipment so that one tank is pumping liquid refrigerant to an evaporator at a predetermined pressure while the other tank is separating liquid and vapor refrigerant substantially at evaporator pressure.

Abstract: An apparatus for simultaneously monitoring the temperature within a refrigerated enclosure and the temperature of the ambient air exteriorly of the enclosure which functions to shut down normal compressor operations and selectively activates one or more primary and auxiliary ambient air inlet supply units dependent upon the temperature of the ambient air when the ambient air temperature is below the temperature within the enclosure.

Abstract: A low resistance backfill material for use in anode beds for cathodic protection of subsurface metallic structures. The backfill material consists of a mixture of carbonaceous materials, a lubricant, and a surfactant, which material may be mixed with water and pumped as a high density fluidized suspension into the anode bed.

Abstract: Apparatus for fighting fires including a plurality of nozzles mounted on an aerial ladder and supplied with water under pressure which is directed onto the fire. Each of the nozzles is controlled from a remote position in a manner such that the direction of the water and the intensity of the water being discharged can be altered as desired.

Abstract: An adjustable stem drop apparatus and method for a fire extinguishing sprinkler mounted on a pipe located above the ceiling of a building and arranged in such a manner that the position of the sprinkler can be adjusted from below the ceiling after the ceiling has been permanently installed.

Abstract: Pump apparatus for injecting combustible fuel under high pressure into a diesel type internal combustion engine. The apparatus includes a body having a cavity with a diaphragm therein and an adjustable variable pressure applied intermittently to one side of the diaphragm causes a selected quantity of fuel to be pumped through the cavity on the other side of the diaphragm.

Abstract: Fuel injection apparatus for injecting gasoline or other combustible fuel into the cylinders of an internal combustion engine. The apparatus includes a fuel injector body having a diaphragm through which a needle valve extends and a constant fluid pressure is maintained on one side of the diaphragm to urge the needle valve toward closed position. A higher fluid pressure is intermittently applied to the other side of the diaphragm so that the needle valve is opened to spray fuel under pressure into the internal combustion engine, and when the higher pressure is relieved the introduction of fuel is interrupted.
