Title: Thrust bearing with fixed pads
Inventor: FOUCHER GERARD
IPC: F16C17/04
Filed: 1982-05-11
Granted: 1986-02-13
Abstract: A fixed pad thrust bearing for a turbomachine comprises a ring of sector-shaped pads separated by grooves and facing a thrust collar integral with the rotor of the turbomachine within a thrust bearing cage integral with the rotor. The ring bears on a deformable ring. Each pad is fed with oil via a space formed in the wall of the cage and facing an orifice in a bore in the pad. A front surface of each pad facing the collar is inclined relative to the rear surface of the ring. Each pad is further formed with a groove communicating with the aforementioned bore but not reaching as far as the inner and outer edges of the pad, being disposed adjacent the leading edge of the pad. The oil is recovered centrifugally from the outer edge of the collar. In this way, virtually all the power consumed by the oil goes towards providing the hydrodynamic supporting force, minimizing the shearing losses between the fixed and moving parts within the thrust bearing cage.

Title: Process and apparatus for the gasification of ligno-cellulosic products
Inventor: DEGLISE XAVIER
IPC: C10B49/22
Filed: 1983-10-22
Granted: 1986-10-16
Abstract: The rapid pyrolysis of lignocellulosic products, especially forest waste, is conducted in a fluidized bed of hot refractory particles. The pyrolysis products, comprising solid carbonaceous residue (i.e., char), tars and gas, escape from the bed and cross an overheating zone comprising a packed bed contactor supplied by a rainfall of hot refractory particles. The carbonaceous solid residue is then separated from the produced gases, a portion of which is recycled to fluidize the bed, and burned in a conveyed bed combustion reactor, thus heating the refractory particles that supply the packed bed contactor and the fluidized bed.

Title: Electronic transfer organ
Inventor: TURNER WILLIAM D
IPC: G10H7/00
Filed: 1983-05-06
Granted: 1988-06-09
Abstract: There is described an electronic transfer organ for precisely duplicating twenty-six known properties of pipe organ sound. The instrument employs identical circuitry throughout, for individualized generation, keying, and decoupling or discriminating of each note. When keyboard keys (01, 02, 03) are depressed, individualized note forming information is selectively transferred from programmed memories (17, 20, 39) for each voice to temporary memories in small numbers of identical tone circuits (15, 18, 21, 23, 27, 30 and 32; 16, 19, 22, 24, 28, 31, and 33). The transferred information causes the tone circuits to individually generate, switch, and decouple each note. Envelope-generating elements in components (15, 18, 21,27, and 30; 16, 19, 22, 28, and 31) preserve smooth individual keying of all notes at their characteristic speeds and distinctive patterns. Dynamic keyers in (12 and 13) duplicate the keying effects of tracker pipe organs. All tone frequencies, derived ultimately from at least one high frequency source are randomly independent in phase, and remain permanently in various degrees of optimal mistune which characterize organ pipes in good tune. A two-dimensional stereophonic system (601, 602, 603, 604) implements the individual effects of tone frequency decoupling, to duplicate the collective sound of organ pipes distributed in various arrays outside and inside organ cases. Overall construction is modular, or divisional, by keyboard and associated elements. Adapted means from the prior art enable the instrument to couple its keyboard, and to duplicate the effects of moderate musical fluctuations in the sounds of individual pipes, vibrato, and the effects of expression controls, and reverberative milieux.

Title: Trilevel sandcastle pulse encoding/decoding system
Inventor: HETTIGER JAMES
IPC: H03K5/00
Filed: 1984-12-13
Granted: 1988-05-26
Abstract: A color TV receiver is provided with an encoding/decoding system for a trilevel sandcastle pulse train, exhibiting a middle pulse level during recurring kinescope bias control intervals, and comprising excursions between a base level, a low pulse level, and a high pulse level during periods outside said kinescope bias control intervals. The system's decoder includes a trio of voltage comparators for comparing incoming sandcastle pulses with respective reference voltages derived from three different intermediate points on a common voltage divider connected across the terminals of a DC supply. The system's encoder includes keyed means for determining the middle pulse level of the trilevel sandcastle pulse train in accordance with the output of a second voltage divider connected across the same DC supply as the first voltage divider. An output of a third, selectively enabled, voltage divider, connected across the same DC supply as the first and second voltage dividers, is determinative of said low pulse level. The third divider is subject to modification during base level appearances, with the base level determined by the third divider's modified output during the periods of divider modification. During high pulse level appearances, the third voltage divider is disabled to establish the high pulse level at or near the full output potential of the DC supply.

Title: Method for determining low horizontal helicopter air speeds
Inventor: HASSENPFLUG WOLFGANG DIPL ING
IPC: G01P5/00
Filed: 1985-06-11
Granted: 1988-04-07
Abstract: The evaluation of the horizontal velocity at low velocities is effected by analytic extraction to obtain extremely accurate velocity values. At least three control functions for the helicopter are measured, one of which provides collective values compared with a stored calibration function to obtain the theoretical horizontal velocity. The remaining measured functions provide the longiutdinal and transverse control values from which the corresponding control profiles are obtained using an approximation method. An interpolation method is then used to provide a pair of phase values for obtaining the air flow angle used to calculate the perpendicular components of the actual horizontal velocity via transformation.
