Circuitry for use in a hand-held electronic probe for passing high frequency current through malignant eye tissue of livestock or other tissue such as warts includes a thermistor in a probe tip that contacts the tissue, producing a voltage that controls a voltage controlled oscillator which drives an audio transducer. If, during treatment, the probe tip is held against the malignant tissue with su...

A shift fork in a transmission has an upwardly extending branch whose upper end is bevelled to introduce dripping lubricant to sliding surfaces of the shift fork branch in contact with a collar with which the shift fork is engaged for shifting gears in the transmission.

A solid-state electrosurgical generator is disclosed which provides output waveforms that are optimized for electrosurgical fulguration. The fulguration output circuitry consists of a radio-frequency tank circuit which is periodically pulsed to produce a periodic damped-sinusoidal output waveform. However, the damping factor is sufficiently low so that many cycles of the waveform occur between per...

In one working operation or in directly successive working operations a tube 2 is extruded having at least two layers of different materials and the wall thickness thereof is structured to be wave-shaped or undulatory, i.e. has thick portions and thin portions at intervals. The thus formed tube sections are then cut from the tube to form the individual inner liners 50. The periodic variation in wa...

The four-wheel vehicle drive system includes a central differential gear assembly, a front-wheel differential gear assembly, a ring gear and a bevel gear. The central differential gear assembly includes: a toothed wheel which engages with a transmission output gear of a power trans...

A core for an automobile bumper comprising a foam having a bulk density of 0.047 to 0.18 g/cm3, the foam being made of an ethylene-propylene random copolymer having an ethylene content of 0.1 to 8.0% by weight, and largely improved in an energy absorption capacity at small strain by means of defining the ratio of ethylene to propylene and the bulk density of a foam.

A nozzle assembly is described for use in a system that forms small gas-filled shells, which avoids the need for holding a miniature inner nozzle precisely concentric with a miniature outer nozzle. The outer nozzle has a diameter which is less than about 0.7 millimeter, which results in fluid passing through the nozzle having a progressively greater velocity at locations progressively further from...

Concentrated, stable water-in-oil emulsions of water-soluble or water-swellable polymers are prepared by polymerization of one or more water-soluble ethylenically unsaturated monomers in a water-in-oil emulsion and removal of water from the water-in-oil polymer emulsion by azeotropic distillation, by a method in which superheated vapor of an inert organic solvent which is immiscible with water is ...

A microporous powder form polylactide which can take up a multiple of its own weight of active material and which can be used for the controlled release of that active material. The aforesaid microporous polylactide powder can be prepared by dissolving polylactide under warming in phthalicacid diethylester, preferably at a temperature over 150 DEG C. and then slowly cooling the clear solution. Th...

Substrates are coated by heating the substrates to temperatures of 120 DEG -260 DEG C. and dipping them into a bath of polyvinyl fluoride dispersed in latent solvent at temperatures below 100 DEG C.

A bar code reader comprises a semiconductor laser diode. A first end face of the laser diode is optically coupled to an end of an optical fiber. A second end face of the laser diode is optically coupled to a detector. The bar code is scanned at the free end of the optical fiber. This information is read by the semiconductor laser diode by way of optical feedback.

In an optical recording system wherein the intensity of a laser beam is modulated with an input modulation signal so as to record information on a recording medium, the intensity modulation of the laser beam is performed after the pulse waveform of the input modulation signal is converted into two pulses which express the front edge and rear edge of the pulse waveform respectively.

Thermostable hydroxystyrylaza compounds are prepared by reacting methylated pyridines and/or pyrazines with one or more monohydroxy aromatic aldehydes having the ortho and para positions to the hydroxy group block with groups inert to condensation reactions. These compounds are useful to make unsaturated derivatives which can cure into high temperature resistant polymers and/or laminates without g...
