Abstract: Two layer simulated fish skin fishing lures having the flexibility, shape, reflective quality, iridescence, and other general features of a particular fish species desired prepared by embossing and metalizing a single layer of clear plastic material that has representations of eyes, fins, and spots thereon and joining the segments of the resultant material at the periphery.

Abstract: A laboratory stand assembly for use in emptying sample vials used to monitor the concentration of solvent vapor in air. The assembly consists of a base, a support extending vertically therefrom with a sample holder adjustably positioned in the support. A clamp is attached to the top of the sample holder to secure the adsorption tube to the sample holder. Support means for receiving a sample vial are also provided.

Abstract: An apparatus for preventing microorganisms from passing from outside into sterile closed systems containing sterile water or other fluids for general or biomedical use.

Abstract: A simulated fish skin impervious to the elements having the flexibility, shape, reflective quality, iridescence and other general features of the particular fish species desired prepared by sandwiching a thin, shiny material with an embossed surface between layers of a clear, flexible plastic joined together at the periphery of the fish skin representation. The structure can be made more lifelike by coloring in the appropriate areas with India inks or other suitable dye material.

Abstract: A sturdy, portable apparatus for detecting water leaks in plumbing equipment consisting of an elongated rod having two upstanding portions and a third portion bent at a 90.degree. angle to the upstanding portions with tubes connecting the upstanding portions to ear pieces, the tubes containing a plurality of wires positioned in close proximity to the upstanding portions of the rod and extending in close proximity to the ear pieces. Leakage of water sets up acoustical vibrations which are transmitted through the metal rod and are picked up by the wires and transmitted to the ear pieces.

Abstract: The invention provides a pesticide containing an aluminium or magnesium phosphide and an ignition inhibiting agent essentially consisting of at least one aromatic hydrocarbon which suppresses the tendency of phosphin evolved under the influence of e.g. atmospheric moisture, to self-ignite.

Abstract: A previously disclosed cartridge type humidifier apparatus including a separate heater module with a cylindrical opening for replaceably receiving therein disposable cylindrical humidifier cartridge modules, having a housing containing a replenishable water supply, is employed as a water supply source for producing an aerosol with an oxygen supply for pediatric inhalation therapy. The cartridge modules each have a tubular metal main body adapted for a sliding fit within a complimentary tubular walled heater. The metal tubular body has rigid plastic top and bottom end portions. The plastic top end portion is a cap with a center axial gas inlet tube, and a separate transverse gas delivery pipe, the cap forming a closed air space over a pool of humidifying liquid.

Abstract: A fire escape, exercise or amusement device designed to depend vertically from a wall when in use and to have sufficient flexibility to simplify storage is disclosed. The device consists of a rope-like support member with a series of beads about 4 to 5 inches in diameter spaced axially along substantially the entire length of the rope-like support. A grasping hook is attached to at least one end of the device for attachment to a support that is an integral part of a building or other structure. Horizontal rods are attached to the top and bottom of the device above and below the beads.

Abstract: An apparatus for manufacture of combustible gas consisting principally of methane with minor amounts of carbon monoxide, carbon dioxide and hydrogen from organic wastes comprising an inverted vessel positioned in a body of water in a matter of such that the water acts as a "liquid door" to trap plant material and gas within the vessel.The combustible gas manufacturing method provided by the apparatus operates at a temperature of about 21.degree. C. to 37.8.degree. C. Under ideal conditions it is possible to produce as much as about 11 cubic foot of gas per pound of organic waste. A moving current of water agitates the organic material and sweeps the waste products from the bottom of the vessel where they may be recovered and used as fertilizer if desired.

Abstract: A system for allowing an operator to accurately observe the liquid level in a tank truck or transport trailer that is filled from a bulk storage tank through a flange on the line from the storage tank that is attached to a matching flange of the tank truck or transport trailer by incorporating a float gauge structure into the flange on the line from the storage tank, thus, enabling the operator to accurately observe the level of the liquid in the tank truck or transport trailer and manually shut off the flow from the storage vessel when the tank truck or transport trailer contains the desired amount of liquid. The system includes sensors designed to indicate sealed engagement of the flange on the line from the storage tanks with the matching flange on the tank truck or transport trailer.

Abstract: A new convenient and more reliable spectrophotometric method for assaying endotoxins at levels as low as 10 ppb. Five different solutions of endotoxins, E. coli 0127:B8, E. coli 055:B5, S. abortus equi, S. enteritidis and S. flexneri were examined and each exhibited an absorption maximum of 259 mm.

Abstract: A method of preparing zeolitic aluminosilicates particularly those zeolitic aluminosilicates that are characterized by pores in the 4 and 10A sizes that are designated Zeolites A and X by the Linde Division of Union Carbide Corporation in which compacts of the Zeolites A and X, metakaolin, clay mixture undergo crystallization at a temperature of 200.degree. to 700.degree. F. The crystallization is carried out in a calciner or other type of drying equipment. Normally the formed particles furnish all of the liquid needed for crystallization. If desired, however, additional steam may be added during the crystallization process.

Abstract: A process for modifying the silica hydrosol used to bind zeolite clay catalysts by adding salts of titania, zirconia, iron or ceria to the silica hydrosol in the course of preparation is disclosed. This addition alters the physical characteristics of catalyst when titania and zirconia salts are added and alters the matrix activity when quadrivalent cerium salts or iron salts are added to the silica hydrosol.

Abstract: A process for cracking hydrocarbon feedstocks by contacting such stocks under cracking conditions with a composite catalyst comprising an improved hydrogen exchanged Y-type zeolite component and an amorphous inorganic matrix component. The use of this catalyst yields cracked naphthas of increased olefinic content for the production of lead-free high octane gasoline. Further improvement in the levels of C.sub.3 and C.sub.4 olefins can be realized by incorporating a portion of calcined rare earth exchanged Y-type zeolite into the composite catalyst.
