Abstract: An ullage gauge for directly and accurately measuring the ullage of a cargo tank of a vessel such as an oil tanker without the necessity of opening the hatch. The gauge is comprised of a calibrated ullage tape which is supplied from a winder reel positioned within a sealed chamber atop the deck of the tanker and communicating with the cargo tank, the winder reel being rotated by a winder reel handle placed exterior of said sealed chamber. The sealed chamber includes a view window which allows direct observation of the calibrated surface of the ullage tape as well as direct observation of the rising cargo within the cargo tank. A float attached to the ullage tape is of sufficient size and weight that once contact of the float with the surface of the cargo is made, such contact is felt by the operator through the winder reel handle.

Abstract: A post emulsifiable penetrant composition for applications and entry into flaws in solid surfaces consists essentially of(a) a first solvent ingredient comprising a high boiling point aromatic hydrocarbon,(b) a second solvent ingredient selected from the group that includes di-phthalates and diesters,(c) epoxidized material selected from the group that consists of epoxidized esters, oils and resins,(d) fluorescent dye, and(e) fluorescent brightener.

Abstract: A process for sealing a phosphate coating on metal includes the steps:(a) wetting the phosphate coated metal with a composition consisting essentially of an aqueous acidic solution containing at least one member selected from the group consisting of hypophosphorous acid, salts of hypophosphorous acid and sodium hypophosphite,(b) and then drying the thus wetted phosphate coated metal.The solution may also contain another member selected from the group consisting of iron, steel, zinc and aluminum.

Abstract: A modular infrared heating device having an outer casing which encloses a heating chamber wherein one or more infrared lamps are vertically positioned. The heating device also includes an intake channel which communicates with an opening in the outer casing and with the heating chamber. At least one heat exchanging plate is positioned within the heating chamber adjacent to the infrared lamps such that it is capable of being heated thereby and defines an air discharge channel with a wall of the casing and. This plate has a plurality of open-ended tubular conduits mounted onto it. Each of these conduits is constructed to have a hollow inner channel and is mounted onto the heat exchanging plate such that its hollow inner channel is aligned with a corresponding opening in the plate.

Abstract: A modular infrared space heating device includes an enclosure having an air inlet and an air exhaust. A plurality of open-ended ferrous metal conduits are positioned in the enclosure between the air exhaust and a plurality of infrared lamps. The conduits are supported at only one end on a ferrous metal sheet. Refractive lens means comprising a glass plate having a plurality of convex focussing surfaces equal in number to the conduits is provided between the lamps and the conduits and arranged so that each convex surface focusses infrared radiation from the lamps on a different one of the conduits. A fan is provided in the enclosure for circulating air through the enclosure from the air inlet, over the lamps, through and around the conduits and out the air exhaust.

Abstract: Transistorized electronic timer circuits installed in motorized vehicles indicate the running time of the devices such as automobiles, trucks, motorcycles and the like which have a factory recommended servicing cycle. Because of the delicate nature of the transistors and timer devices and the presence of transient noises in automobile electrical systems, protective circuits were developed to prevent timer failures which might result in failure to meet engine service requirements or, in the case of newer vehicles, emission tests, etc.

Abstract: An ullage gage for directly and accurately measuring the ullage of a cargo tank of a vessel such as an oil tanker without the necessity of opening the tank. The gage is comprised of a calibrated sword which is affixed to the underside of a cover plate which also contains a viewport for viewing the sword. The cover plate sealingly covers a service opening in the tank. The first calibration mark on the sword coincides with the underside of the deck of the vessel and has a value equal to the actual vertical distance from the lip of the ullage hatch to the underside of the deck at a point adjacent the gage. An adjustable means is provided to adjust the sword with relation to the cover plate to compensate for different deck thicknesses and/or deck camber of the vessel.

Abstract: An easily removable cover plate for sealingly closing a service opening or the like through a deck of a vessel into a cargo tank. The cover plate has a plurality of latch means spaced about its periphery which are adjustable without disassembly to compensate for different deck thicknesses with which the cover plate may be used.
