Abstract: ABSTRACT OF THE DISCLOSURE      An improved heating torch having the usual fuel and oxygen passageways and valves for controlling the flow of the respective components, mixer for mixing fuel and oxygen, and tip for flowing the admixture exteriorly thereof for burning to heat a work piece or the like, the improvement being characterized by a multiple piece tip that is spring loaded such that one or more internals can be spring loaded to be retained within a shell that is affixed to an end piece of the tip.  The end piece fastens to the end of an elbow connected with the mixer, and has the shell disposed about the end piece; and one or more tip internals are disposed inside and biased toward their normal assembled position by a spring or the like.  Different sized heating tips are readily formed by simply adding internals and larger sized end pieces and shells to form one or more rings of grooves defined by splines that can be easily manufactured and assembled.  In addition, the heating torch tip is amenable to underwriter approval, since it alleviates problems with flashback and burning due to striking of a heating tip against a work piece or other objects during handling.

Abstract: ABSTRACT: AN IGNITION DEVICE FOR CHEMICAL OXYGEN GENERATORS     Chemical oxygen generators are used in protective respiratory and resuscitation  apparatus, in order to provide an oxygen supply.   In chemical oxygen generat-ors the oxygen is present in a chemically combined form and, when needed, is released when igntion is triggered during the course of a chemical reaction.    The ignition device formed from an igntion mixture is usually disposed in the top part of the chemical oxygen supply, present in the form of a candle.   From here, after ignition, the reaction continues until the candle is spent.     The igntion device of the invention remains thermally stable up to temperatures of at least 100°C, in order to safeguard the storage stability of the oxygen generators; nevertheless, the igntion devices can be activated by water and even by a momentary elevated temperature.     The igntion composition comprises a mixture of an alkali metal-oxygen compound, combined with an oxygen-containing silicon compound, a percarbonate, a metal peroxide or superoxide.

Abstract: SWITCHED CAPACITOR COUPLED LINE RECEIVER CIRCUIT            Abstract A receiver circuit uses a switched capacitor circuit to couple either analog or digital signals received over a two lead communication facility to connected apparatus.  During a first time interval, a capacitor is connected across a lead of a facility to sample the facility voltage.  During a second time interval, this capacitor is disconnected from that lead and reconnected in series between the second facility lead and the input to a voltage regenerator circuit.  An appropriate regenerator circuit is selected to reconstruct either the received analog or digital signals for output to connected apparatus.

Abstract: ABSTRACT    An apparatus for detecting the presence and/or measuring the concentration of an analyte in the fluid medium is disclosed.  The apparatus relies on biospecific binding between a biochemical binding system and the analyte to change the dielectric constant within a first volumetric region of a capacitive affinity sensor.  In one embodiment referred to as the direct binding configuration, a binding agent, such as an antibody, is immobilized on the surface of an "open" capacitor.  An analyte such as a specific bacteria, virus, or large molecule is drawn to the surface of the capacitor through specific biochemical binding with the antibody and alters the dielectric of the capacitor.  In a  second, competitive binding configuration, the analyte or its analog is immobilized on the surface of the "open" capacitor and has specifically bound to it a binding molecule, such as a specific antibody.  When free analyte under test is introduced into the system it competitively displaces the binding molecule from the immobilized analyte until equilibrium is reached.  Movement of the binding molecule from the capacitor's surface alters the dielectric of the capacitor.  The "open" capacitor is designed so that the displaced binding molecule has a short diffusion distance from the capacitor surface, where the electrical field intensity is high, to an area where the electrical field is low.  Such movement of the binding molecule causes the displacement of fluid molecules having a higher dielectric constant which thereby alters the capacitor's dielectric properties.

Abstract: ABSTRACT A single cylinder internal combustion engine has an inline counterbalance weight system (12) which includes a counterbalance shaft (40) rotatably mounted to a crankcase and extending generally parallel to a crankshaft (26) of the engine and transverse to and aligned with the rectilinear path of reciprocation of the piston (24) pivotally connected to the crankshaft, and a counterbalance weight (42) eccentrically mounted on the counterbalance shaft. The counterbalance shaft,and weight are rotated in a direction opposite to the direction of rotation of the crankshaft.  The crankshaft and the weights (38) mounted thereon and the counterbalance weight (42) are aligned with and disposed in symmetrical relation-ship to the rectilinear path of the piston.  In such arrangement, vibration imbalance in the engine in the direction of the rectilinear path of the piston is substantially eliminated due to the force vector of the reciprocating piston being generally balanced by the force vectors of the rotating counterbalance weight and the crankshaft and weights thereon when the piston is at opposite end positions of its stroke.  Also, the rocking imbalance in the engine is substantially eliminated due to the generally equal displacement of the force vectors of the reciprocating piston, the counterbalance weight and the crankshaft and weights thereon from the mounting base defined on the crankcase and the generally balanced relationship of the force vector of the rotating crankshaft and weights thereon with the force vector of the rotating counterbalance weight when the piston is at an intermediate position between opposite end positions of its stroke.

Abstract: Recombinant DNA has been developed which is derived from the plasmid pUB110. This plasmid comprises a gene coding for resistance to kanamycin or to analogous antibiotics inactivated by the nucleotidyl transferase enzyme.The recombinant DNA containing an amylase-coding gene is prepared by the in vitro process of cleaving DNA derived from a donor microorganism and combining the resulting DNA fragments comprising the amylase-coding gene with a similarly cleaved vector which is plasmid pUB110. This recombinant DNA may then be introduced into a host microorganism and the resulting genetically engineered microorganism has been found to have enhanced stability and high copy numbers.The host microorganism employed is preferably Bacillus subtilis and the invention is particularly suitable for the industrial scale production of the alpha-amylase of Bacillus megaterium.
