Title: Method for varying oscillation frequency of high-frequency oscillator
Filed: 2011-06-22
Abstract: The switching element is provided in a state of being electromagnetically coupled to the cavity resonator of the high frequency oscillator; the bias voltage applying terminal is connected to one electrode of the switching element; another electrode of the switching element is electrically connected to the cavity resonator (the anode shell in FIG. 1); the metal plate having a size enough for reflecting an electric wave to be transmitted before and after the switching element in a high-frequency manner is provided at any one end of the switching element; and by applying a bias voltage to the switching element and varying that, a reactance of the switching element is changed and a resonance frequency of the cavity resonator is varied. By this method, an oscillation frequency can be varied greatly relative to a small change in a bias voltage.

Title: Apparatus and method for heatless production of hollow items, e.g.foundry shell cores
Inventor: MICHELSON ANATOL
IPC: B22C13/08
Filed: 1981-05-26
Granted: 1985-06-13
Abstract: Two permeable-to-gas patterns [68] form an inner cavity [54] of desirable configuration and are enclosed by non-permeable halves of the pattern box, forming an outer cavity or flow space [70]. The pattern box [32] is mounted on two plates of the rotatable cage assembly, selectively positionable in at least three positions: charge, discharge, and transfer. Above the pattern box [32] are pivotally mounted material supply means [44], sealing means [96], and a trimmer [46]. Below the pattern box is a receiver [16] of an airless conveyor [14] for recirculation of the discharged unhardened material. The pattern box is connected to two manifolds: [61, 63] one [63] for consecutive supply of catalyst gas and the compressed air, another [61] for axhaust and venting. After material has been blown with the help of compressed air from the material supply means into the pattern inner cavity, it is sealed and the air is flushed out of the system by compressed catalyst gas introduced into the pattern box for about one second. Said gas then penetrates to desirable depth into material's outer layer starting polymerization and curing of its binder. After a few seconds, unsealed pattern box assembly is turned upside down and compressed air is blown into the pattern box, dislodging unhardened portion of the material out of the inside of the produced shell-like product. Consequently, the pattern box is opened and the product is transferred from the apparatus to a suitable place outside the machine.

Granted: 1988-02-04
Abstract: Structured latex particles comprising water-soluble, nonionic, organic polymer core encapsulated with a thin layer of a copolymer and having chemically bound, pH independent ionic gps. are prepd. by emulsion polymerising monomers in presence of polymeric surfactants. The novelty is that these surfactants are bound to the structured particle surface in an amt. sufficient to provide the major portion of the colloidal stability of the latex but insufficient to make the polymer water soluble. Pref. The charge density of the surfactant is 1.8-3.0 (pref. 0.15-0.6) m.equiv./g of particles. The latexes have improved chemical and mechanical stability. They are used for making high strength non woven fibrous composites and coatings.

Abstract: A controlled electric drive (CED) device comprises a pair of rectangular magnetic poles of different polarity arranged adjacent, parallel, and congruent to each other with a relatively narrow gap therebetween, providing an essentially uniform magnetic field between the pole faces. The device further comprises a driver conductor arranged to move freely between the magnetic pole faces in such a manner that an electric current running through the driver conductor will tend to move the conductor out of the magnetic field at right angles to the conductor and to the direction of the magnetic lines of force defining the magnetic field. The device further comprises a controller conductor wound in a flat, essentially rectangular spiral fixed adjacent to, and insulated from, the driver conductor. The controller conductor is so arranged that its longitudial direction is parallel to the driver conductor, and has first and second portions, with direct corrent flowing in opposite directions in each of the portions. Further, there is provided a multiplicity of controllers comprising single conductors, multiple conductors, rectangular magnets, shaped magnets, and shaped magnetic gaps.

Title: Electronic circuit arrangement comprising a switching device and fault indicator
Inventor: BUCK ROBERT
IPC: G08B29/04
Filed: 1983-02-12
Granted: 1986-01-30
Abstract: A contactless motion detector, specifically an oscillator whose signal amplitude is attenuated or enhanced by the approach of a monitored metallic element, is periodically switched for brief periods into its alternate state by a train of short test pulses giving rise to corresponding checking pulses that are superimposed upon the integrated output voltage of the oscillator whereby that voltage is intermittently increased when at low level and/or intermittently reduced when at high level. These checking pulses, whether of the voltage-increasing or the voltage-reducing kind, are integrated to provide an enabling signal allowing a controlled load to be energized or de-energized according to the mean value of the output voltage; an absence of the enabling signal indicates a malfunction.

Title: Photosensitive compositions and products
Inventor: CERAMI ANTHONY
IPC: G01N21/78
Filed: 1983-02-09
Granted: 1987-04-23
Abstract: A photosensitive composition is disclosed, which is capable of offering a visual, calibrated reaction to the presence of ultraviolet radiation. The composition comprises a complex of a leuco dye and animal-derived serum albumin. The preparation of this complex has been found to stabilize the leuco dyes, to avoid fading after the presentation of a color reaction upon exposure. Also, the leuco dye-serum albumin albumin complex is capable of exacting calibration, so that scientifically significant quantitative measurements of ultraviolet light exposure can be made. Moreover, the present composition eliminates the need for the addition to the leuco dye of various activator compounds, that are chemically unstable, e.g. volatile, or present potential exposure to toxicity, in the instance where personal applications for the photosensitive composition are contemplated. The present invention includes a method of preparing the photosensitive composition, including the preparation of an ultraviolet light indicator.

Title: Working depth control system for vehicle with ground working inplement
Inventor: WIEGARDT GORDON K
IPC: A01B63/111
Filed: 1983-03-21
Granted: 1989-03-02
Abstract: A tractor (10) includes a hitch (26) for pulling a ground-working implement. A hydraulic cylinder (34) is extensible and retractable to lower and raise the implement. A control system (50) senses operating parameters, including wheel slip, engine speed, draft force and implement or rockshaft position. Error signals are derived from the sensed wheel slip, engine speed and draft force and correspond set point signals. The error signals are combined into a composite or combined error signal. The larger of (a) the combined error signal and (b) a separately determined position error signal, is selected and converted to a pulsewidth modulated valve control signal which is applied to a control valve (42) which then actuates the cylinder to move the implement to reduce the magnitude of the selected error signal. Certain set point signals are derived from the corresponding parameter signals themselves.
