Patent EP-0605223-A1 (EP)
Inventor: HITE RUSSELL E
IPC: F02F5/00
Filed: 1993-12-23
Abstract: A base body 26 of a piston ring 20 has a gas nitrided layer 28 formed on its outer peripheral face 24. A metallic nitride, such as chromium nitride, face coating 30 is then formed on the gas nitrided layer 28. The gas nitrided layer 28 acts as a very hard substrate which prevents chipping of the chromium nitride face coating 30. Damage to the chromium nitride face coating 30 is also minimized because of the increased bond strength between the two layers. The face coating 30 has a high density, low coefficient of friction, high hardness and correspondingly high scuff resistance. The invention also incorporates a preferred method of applying the face coating wherein the gas nitrided layer 28 is lapped and polished to remove surface irregularities.

Abstract: When manufacturing a cigarette which is completely or partly formed of strands or sides of expanded tobacco or short strands, or else containing a smaller amount of tobacco, difficulties are encountered in obtaining a cigarette which has an acceptable measured compressibility value. By providing a cigarette-manufacturing machine (1) with a cam (3) which has at least one additional bearing surface (32A, 33A, 34A, 35A) it is possible, just before the operation (15) of nipping the top off the twist (20), to compress a certain number of regions (22) of the said twist, thereby increasing the tobacco density in these regions. A cigarette including one or more regions (22) with a tobacco density which has been increased in this way has a measured compressibility value which is equivalent to a normal cigarette. <IMAGE>

Abstract: The process serves for making a material based on a doped intermetallic compound. In carrying out the process, at least two differently doped powders each based on the intermetallic compound are selected. One of the two powders contains predominantly coarse-grained particles. By contrast, another powder is formed from comparatively fine-grained particles of a material having a lower creep strength but a higher ductility than the material of the coarse-grained powder. The at least two powders are mixed with one another in a ratio serving to adjust a desired mixed microstructure and are then hot-compacted and heat-treated to form the material. Material produced by this process is suitable for components which are exposed to high mechanical stresses at high temperatures, such as, in particular, gas turbine blades or turbine rotors of turbochargers. <IMAGE>

Filed: 1994-09-22
Abstract: A line frequency is determined by interleaved sampling of ambient light to obtain analog voltage samples at predetermined sampling rates associated with two or more line frequencies. Where there are two line frequencies, one method separates the first samples by a time period at least equal to an analog-to-digital conversion time, and less than the earliest time when a sample associated with one line frequency would coincide with a sample from the other. There are n samples per flicker frequency period and Q samples for each line frequency are taken. In a second method, a first common sample is taken for all line frequencies, and a condition characterized by simultaneous samples for different line frequency sample groups triggers a common sample for all line frequencies. For both methods, digital sample values one through Q-1 for each group are operated on to obtain a result, and then two through Q are similarly operated on to obtain a second result. The result for samples one through Q-1 for a given line frequency is compared to the result for samples two through Q. If the results for a given line frequency are within a predetermined limit, the presence of that line frequency is indicated. The known line frequency can be used to set the light sampling rate for exposure setting, as well as imprinting light source information onto photographic film.

Abstract: The Hall sensor circuit includes a Hall element (10) that is preferably followed by a Hall-voltage amplifier (11), and a pole end of a magnet is preferably fixed adjacent to the Hall element. The amplifier output is connected directly to one of a pair of differential inputs of a Schmitt trigger circuit (29) and is also connected, via a single or a dual-polarity track and hold circuit (18,19,20), to the other of the differential Schmitt inputs. The dual-polarity track and hold circuit (18,19,20) causes the voltage across a capacitor (20) to track positive and negative Hall voltage slopes, and to hold the positive-going peaks and negative-going peaks of the Hall voltage presented to the fore-mentioned other Schmitt input so that when the difference voltage between the Hall voltage and the held voltage of the capacitor (20) exceeds a positive or negative threshold of the Schmitt circuit, the Schmitt circuit (29) output changes binary state indicating the approach or the receding of a ferrous-gear tooth. The dual-polarity track and hold circuit is made up of two complementary plus and a minus peak detector circuits (Fig.11), each including a bipolar transistor (53,83) having an emitter connected to the voltage-holding capacitor (54), an operational amplifier (52,80) with an output connected to the base of the transistor (53,83), the amplifier having a negative input connected to the transistor emitter and a positive input serving as the input of the each Hall voltage tracking and holding circuit.

Abstract: A sports lighting fixture having improved light delivery characteristics includes an elongated bare arc tube, high intensity discharge lamp disposed near the apex of a parabolically shaped reflector member. The reflector is constructed of a non-metallic material and by the orientation and positioning of the lamp within the reflector, an essentially oval shaped light pattern is generated. A light transmissive cover is disposed over the open end of the reflector. When projected onto the playing surface of a sports field, the oval shaped light pattern translates to an essentially circular shaped pattern which allows for a more uniform and efficient overlapping of the multiple light outputs at the playing field level. Louvers can be disposed within the reflector to further redirect any high angle light output into a lower angle which is more useful at the playing surface level.

Abstract: A binary diffractive optical element (100) filters the amplitude intensity and the phase of an incident light beam by only transmitting a specified percentage and specified phase of the incident light beam into a zero order, non-diffracted beam while the rest is diffracted into the first or higher orders. The phase level (110) of the binary surface relief phase grating structure can be adjusted relative to the total period (P) of the grating to adjust the amount of diffraction and thus control the amplitude of intensity and the phase of the incident beam transmitted through and diffracted by the grating structure. The phase of the zero order, non-diffracted, transmitted light beam cycles from 0 to Π to 0 while the optical transmittance of the intensity cycles from 100% to 0% to 100%.
