More particularly, said headwear includes a mask having a pair of eyeholes and a band for encircling the wearer's head and attaching said mask thereto and for holding the eyeholes in said mask in registry with the wearer's eyes, said mask being a plate, preshaped to conform to the wearer's face and leaving the lower part thereof free, a bag with a rounded bottom formed of netting having patches of preselected colors and having a pair of eyeholes, said bag adapted to fit loosely over the wearer's head and drape down over his neck, and means for attaching said mask on the inside of said bag such that the eyeholes in the mask are aligned with the eyeholes in the bag.

Abstract: Methods and materials are disclosed for quantitative detection of isoenzymes of creatine kinase having a B-subunit by radioimmunoassay competitive displacement techniques with antibodies to human MB CK. The antibodies are specific for MB and BB creatine kinase and have no cross-reactivity with MM creatine kinase. Radioisotopically labelled isoenzymes with of creatine kinase having the same affinity for antibodies raised against human MB CK are also disclosed, which with the aforementioned antibodies provide a highly sensitive radioimmunoassay capable of measuring picomolar amounts of MB CK or BB CK.

Abstract: This invention relates to the field of organic chemistry, and more particularly, to a method for the preparation of p-aminophenol.

Abstract: Methods and materials for quantitative detection of MB and BB isoenzymes of creatine kinase by radioimmunoassay competitive displacement techniques involving antibodies to human BB isoenzyme which are specific for the B monomer, react with BB CK and cross-react with MB CK, but do not cross-react with MM CK. An acylating agent is employed to radioactively label purified CK isoenzymes used as antigens. Incubation is preferably carried out in a Tris buffer having a pH of about 7.4, in the presence of a suitable organic reducing agent such as mercaptoethanol.

Abstract: A therapeutic composition is disclosed for use in improving the physiological tone of the oral tissues, which among other beneficial effects nourishes said tissues and causes them to approach normal condition. The therapeutic composition also has an antimicrobial effect on the oral microflora including those difficult to eliminate pathogenic genera known to be implicated in dental caries and periodontal disease. The therapeutic composition comprises a pharmaceutically acceptable, water soluble zinc salt and ascorbic acid or an active analog thereof. The zinc salt and the ascorbic acid are present in an amount sufficient to provide a synergistic combination which has a greater than additive antimicrobial effect on such oral genera as Actinomyces, Streptococcus, Staphylococcus, Candida, Pseudomonas and Escherichia.

Abstract: An implement for cleaning storm sewers and culverts having a tubular configuration has a carriage assembly with radially extending cutting means at a forward end and a corresponding radially extending plunger means in spaced relationship therewith at a rearward end, together with means for wetting dirt in the culvert in advance of the cutting means and further means for wetting the dirt in advance of the plunger means.

Abstract: A machine operated implement for cleaning box culverts and other drains and waterways which are generally rectangular in cross section has an elongated body with a plow means at a forward end and a plunger means at a rearward end together with means for wetting dirt in the culvert in advance of said plow means and further means for wetting the dirt in advance of said plunger means.

Abstract: A puzzle for teaching coagulation theory including three separable units representing the intrinsic, extrinsic and common coagulation pathways. Each of said units further including separable members representing the coagulation factors, said members, when assembled correctly, representing the order in which the factors interact.

Abstract: The burr formed on the breakout side of a workpiece during a drilling operation is removed by a deburring bit positioned underneath the workpiece in axial alignment with the drill bit. The drill bit is of the twist type and has at least two longitudinal flutes joined by a web and separated by an equal number of longitudinal lands. The deburring bit has a number of radially extending cutting elements which project radially outwardly from adjacent the bottom of each flute to substantially beyond the diameter of the hole. At the bottom of the flutes, the radially extending cutting elements are spaced to pass the web of the drill bit axially therebetween and to engage the flutes when the drill bit is rotated.

Abstract: An injectable chemical compound capable of producing sterility in male animals having scrotal testes for use in selectively controlling the exocrine function of the testes in the production of sperm and the endocrine function in the production of testosterone. Said injectable chemical compound being a physiologically acceptable astringent, preferably a water soluble zinc compound, a tannin or combinations thereof. Various concentrations of said compound being selectively injected directly into the testes or into the scrotum to suppress spermatogenesis and, optionally, to suppress production of testosterone.

Abstract: A spark ignited internal combustion engine having a carburetor and a mechanical refrigeration system improved with means for cooling the fuel inducted into the carburetor.

Abstract: A security system consists of a central digital processor system, e.g., a general purpose computer, to which plural remote units are connected by a digital communications link, e.g., telephone. The remote units include plural alarm sensors such as intrusion and heat sensors. In a data base of the central processor system are stored segments of data associated uniquely with remote premises having the remote units. The processor system includes a terminal for delivering alarm message reports, such as to a law enforcement agency. Specifically, the remote units have interrogation circuitry for interrogating the sensors to determine if they have been tripped, logic circuitry for causing transmission to the central processor system via the communications link of a sensor alarm data message in digital format signifying the sensor address and its tripped status.

Abstract: A basting device for injecting fluid flavoring material under pressure, said device including a hollow elongated member with perforations adjacent one end and with an annular flange adjacent the other end. A tip having a pointed head for penetrating a food article is threadedly attached to the end of the elongated member adjacent the perforations. A bowl is threadedly attached to the flange, said flange forming a cover and including peripheral grooves communicating with the bowl for pressure relief if the device becomes plugged, said elongated member extending through the flange and including perforations for straining the flavoring fluid.
