Methods of determining the weight, density or volume of solids and the weight and density of liquids are also disclosed.

Abstract: The extraction of fibres from corn husks and/or leaves or corn husks alone is accomplished to provide fibres which are substantially free of the vegetable binder material. The corn husks (and leaves) are preferably allowed to dry to a substantially moisture-free state and are then soaked in a caustic solution for a predetermined period in which the caustic solution frees the fibres from the vegetable matter of the corn husks (and leaves) and reacts with the fibre to strengthen the same. Before the caustic material has an opportunity to degrade the fibres of the corn husks (and leaves), the caustic solution is diluted by rinsing the corn husks (and leaves). While still wet, the fibrous material is straightened so as to dispose the fibrous components of the corn husks (and leaves) in substantially parallel arrangement and in the process the excess binder material is separated from the fibrous material.

Abstract: A capsule for use in anchoring contains as dry ingredients a so-called high alumina cement, a set retarding agent and at least one water-soluble lithium salt. The capsule has a perforated wall and in use is wetted in water to form a self-setting anchoring composition which has a controlled initial setting time followed by an acceptable final setting time after a short interval.

Abstract: A method of using carboxyfluorescein in ophthalmic studies comprising applying of the eye an effective amount of at least one active isomer of carboxyfluorescein.

Abstract: A swim suit designed for competitive racing is made of knit mesh fabric of hydrophobic synthetic stretch yarn knitted in a small atlas type of pattern having a multitude of openings therein. The yarn is within the range of 40% to 100% denier so that the openings comprises in the range of 40% to 60% of the fabric, whereupon the entire suit has flow-through characteristics, that is, water and air pass freely through the openings in the mesh, thereby avoiding entrapment of water and/or air, with resultant avoidance of billowing and bubbling while being sufficiently opaque to conceal the underlying body of the wearer. Both men's and women's suits are provided and each includes a liner portion formed of the same fabric as the swim suit.

Abstract: A cartridge assembly for the securement of anchor bolts in bore holes. The assembly comprises a cartridge having one component of a self-setting mix in a thin plastic casing, a chamber secured to the cartridge and having a sidewall with plural openings, and mechanical perforating means interposed between the cartridge and chamber. The second component of the mix is located within the chamber. The perforating means is arranged to mechanically rupture the cartridge and cause its contents to be carried to the chamber so that the two components intermix thoroughly and extrude through the chamber sidewall openings into the bore hole.

Abstract: Dyphylline is used preferably as the active ingredient in a cream base for topical application to the skin in the treatment of psoriasis and atopic dermatitis. The invention involves the method of use of dyphylline, as well as dyphylline containing compositions.

Abstract: A covering adapted to be worn on the body of a person and formed of a fabric having an inner and an outer surface. Each of the surfaces includes a moisture barrier thereon. Each moisture barrier includes a multitude of small openings therein exposing the moisture absorbent material to the air trapped between the covering and the body of the person. One of the barriers is metallized to reflect radiant-energy and the other barrier is darkly colored to absorb radiant-energy. In one embodiment, the covering is arranged to be releasably secured within a conventional garment to absorb moisture trapped therein. In another embodiment, the covering forms a garment itself.

Abstract: A molded plastic hanger and a clip for use therewith or with other members. The hanger includes a body portion having a diverging pair of arms including slots therein and a crossbar for mounting garment holding clips. A plastic swivel hook is connected to the body portion at a stem. The stem includes a shaft having an annular locking recess in its periphery which is adapted to be received within a mating socket of the hook to connect the hook and body portion to each other while enabling them to be swiveled readily with respect to each other. The clip is arranged for securement to the crossbar of the hanger or to any other rod-like element and is formed of a three piece construction comprising a pair of plastic jaws and a resilient U-shaped member, also formed of plastic, but having a higher tensile strength and resiliency than the plastic of the jaws.

Abstract: A portable, self-contained kit for on site auditing of the energy consumption characteristics of a building having a heating system and for providing a permanent written record of said audit. The kit includes measuring means for measuring various parameters relating to the energy consumption characteristics of the building and computing means including input means and printer means. The kit also comprises audit form means including at least one page having text portions preprinted thereon at predetermined spaced locations and blank areas located immediately adjacent respective text portions. The blank areas are arranged for mounting a section of a printer output tape thereon. The input means is arranged to provide input data in the form of measured parameters and other source data to the computing means for analysis.

Abstract: An overboot arranged to be worn over a shoe or other footwear and formed as an integral unit. The overboot includes an upper portion, a sole portion and a heel portion. The sole portion includes plural elongated cleats extending across the full width of the sole and comprising raised members having grooves therein. Plural undulating ridges project up slightly from the grooves. The space between adjacent cleats is in the form of grooves. Each of the cleats is disposed at a predetermined angle to the longitudinal axis of the sole. The angle is approximately the angle made with the axis by a line extending from the second to the fifth metatarsal head of the wearer's foot to facilitate the flexure of the sole as the wearer walks in the boot, while providing for good traction and the releasement of soft adhering materials, such as mud, slush, snow, etc., from the boot sole.

Abstract: In anesthesia apparatus for supplying oxygen and an anesthesia gas through respective flow control valves to a patient breathing circuit an oxygen flow ratio controller is provided. The system includes a restrictor in the pipeline of the oxygen flow control valve and a restrictor in the pipeline of the anesthesia gas flow control valve. The oxygen flow ratio controller includes differential pressure sensing means and anesthesia gas flow control means, the differential pressure sensing means includes a diaphragm assembly responsive to the pressure in the oxygen pipeline and another diaphragm assembly responsive to the pressure in the anesthesia gas pipeline and is coupled to the restrictor pipelines. The anesthesia gas flow control means controls the flow of gas to the anesthesia gas pipeline. The diaphragm assemblies are opposed to each other and are coupled together by a displaceable linkage.

Abstract: A cartridge containing fast acting inorganic adhesive system, grouting compositions and method of use comprising in the preferred embodiment first and second components which are separately maintained as in a two component cartridge until just prior to use. The first component comprises a paste which includes magnesium oxide, a dispersing agent, such as a ligno sulfonate and water. The second component is comprised of a dihydrogen phosphate salt, such as mono hydrogen ammonium phosphate or sodium dihydrogen phosphate, and the combination of a trisodium phosphate and a second agent selected from the group consisting of a polyphosphate salt and an alkyl acid phosphate or both. The second component will also include a minor amount of water to make the paste.

Abstract: Coacting swaging dies for swaging a splice sleeve onto a reinforcing bar. The dies each include a recess in their coacting surfaces. The recess in each surface includes at least two longitudinally extending ribs projecting from said recess for forming longitudinal indentations in the splice tube when said tube is squeezed between said dies. The lands between immediately adjacent ribs are concave. The ribs are so located that when the dies are in contact the recesses conjoin to form an overall polygonal shaped opening, with the ribs being equidistantly spaced thereabout.
