Abstract: ABSTRACT OF THE DISCLOSURE     An electro-magnetic low frequency therapeutic system comprising a magnetization coil for creating an electro-magnetic field in response to a preselected treat-ment signal whereby the magnetic field has a desired treat-ment characteristic.  The magnetic field has an adjustable intensity set by adjustable control means.  The control means also is provided with circuit means for controlling the peak amplitude of the field for achieving a specific modulation of the peak amplitude in a given time.  The control means further has means to select the orientation and/or direction with respect to a tissue to be treated.          Still further, the control means has circuit means to select the repetition frequency, either pulsating or sinusoidal, fed to the magnetization coil to obtain a selected one of dif-ferent therapeutic signals.  Still further, the control means is provided with means to select a desired treatment time.          An automatic demagnetizing means is also provided and res-ponsive to a preselected demagnetizing time and mode for attenuating the field in a desired manner to terminate a magnetic field treatment.

Title: Electrical contact construction for air-blast  circuit breakers
Inventor: HESS RUEDIGER
IPC: H01H1/06
Filed: 1979-11-01
Granted: 1982-10-12
Abstract: Abstract of the Disclosure An electrical contact construction for air-blast circuit breakers, particularly blast-piston or "puffer" type breakers, which subject the arc drawn during current interruption to a compressed-gas blast as well as a magnetic-force effect which lengthens the arc.  To increase the inter-ruption capacity of such breakers, and particularly to improve arc behavior during the interruption process, a tubular member is disposed within the interior spaces of the tubular contacts of such a breaker in which the switch-ing gases flow.  The member has an inner surface which is conically shaped and is matched to the contour of openings provided in nozzle members dis-posed at the end faces of the tubular contacts to improve gas flow.

Abstract: PRINT HAMMER DRIVE CIRCUIT WITH COMPENSATION          FOR VOLTAGE VARIATION                         Abstract A print hammer drive circuit is driven by a voltage supply having inherent voltage variations.  The driving current is applied to the print hammer coil and the level of the current in the coil detected.  After the level of the current in the coil reaches a predeter-mined maximum level a timing circuit is initiated to control the duration of application of maximum current. Variations in supply voltage on the duration and force of strike of the print hammer have greatly reduced since all timing is based relative to the time that the predetermined drive current level is achieved as dis-tinguished from timing which includes the rise time of the driving current wave form.  Also the effects of variations in inductance from coil to coil can be compensated for by adjustment of the timing circuit.

The section is comprised of a length of tubing having mating male and female threads formed on the tubing adjacent to ends thereof for use in releasably connecting sections together.  A compressible seal is carried by the tubing adjacent one end thereof for sealing connections to other sections.  A frusto-conical sealing surface is formed on the tubing end opposite the compressible seal for sealingly engaging the seal on an adjacent connected section.  The apex angle of the cone of the sealing surface, the compressibility of the seal, the lead of and the friction between the threads and the outside diameter of the pipe are so interrelated that the necessary torque to connect the sections together by threaded engagement and to provide an effective seal by compression of the seal is less than the torque an ordinary worker can apply solely by hand to the section whereby hand makeup of the connection is possible.

Abstract: Abstract of the Disclosure An engine piston and ring assembly providing improved oil control and where applicable sealing of scavenging air.  In a preferred embodiment applicable to two-cycle port scavenged diesel engines and similar applications, the piston is provided with dual oil ring grooves near its open end, which is free from drain openings through the wall in the vicinity of the ring grooves to the oil cooled hollow interior of the piston. Drainage of lubricating oil scraped from the cylinder walls by the rings is provided instead by scalloped recesses in the lower wall surface extending from the open end of the piston to the nearest ring groove.  The arrangement reduces leakage of scavenging air from the inlet ports to the engine crankcase as well as the oc-casional flooding of the piston rings with the cooling oil from the piston interior.

Abstract: ABSTRACT OF THE DISCLOSURE         A loudspeaker system including a low frequency loudspeaker as well as midrange and high frequency loud-speakers and an LC crossover network, is disclosed.  The LC crossover network includes an auto-transformer which not only serves as a component to determine a crossover freqeuncy but which also boosts the electrical signal that is input to the electroacoustic transducer of a less efficient loudspeaker.  The autotransformer increases the output of the less efficient loudspeaker and accommodates its use with more efficient loud-speakers so that the overall loudspeaker system operates at optimum efficiency. An illustrative embodiment of the loud-speaker system affords 108 dB SPL output at one meter with one watt input which corresponds   to about 20% overall efficiency.          The smoothness of amplitude response over the range of audible frequencies that is necessary for high fidelity sound repro-duction is improved by inclusion of peaking circuits in the LC crossover network of the loudspeaker system to enhance amplitude response in the regions of crossover frequencies.

Abstract: ABSTRACT OF THE DISCLOSURE         Methods and apparatus adaptable to continuous pro-duction of hydrogen sulfide from chemical reaction of sulphur with various gaseous sulfur-reducing reactants selected from hydrocarbons, carbon monoxide, carbon-containing compounds such as carbon disulfide, hydrogen, or mixtures of such gases are provided utilizing a fired process sulfur heater to vapor-ize liquid sulfur feed stock.         Control of the temperature of the sulfur vapors and the amount of liquid sulfur feed are used to modulate sulfiding reaction temperatures.         Viscosity of the liquid sulfur feed stock is modified by contact with product gases in order to facilitate flow rate control as liquid sulfur is pumped into the sulfur vaporizer where its temperature increases above about 300°F.         Steam for hydrolysis purposes is introduced with the sulfur vapors, to augment temperature modulation of the sulfiding reactions, and/or with the reductant gas to assist in heat recovery from the reaction product gases.         The system is operated at pressures above atmospheric as determined by a back pressure established in removing hydrogen sulfide product gases.  Controlled movement of reactants and reaction product gases through the system is achieved without mechanical flow control equipment in any of the relatively high temperature zones approaching sulfiding reaction temperatures or sulfur vaporizing temperature.
