Title: Rotor of a compression-wave engine
Inventor: ALTHAUS ROLF
IPC: F02C3/02
Filed: 1990-02-21
Abstract: ABSTRACT OF THE DISCLOSURE       The rotor (1) of a compression-wave engine has cells (6) on its periphery which are concavely curved on the two end faces of the rotor (1) inwards towards its center and towards the rotor axis.       Consequently,  the  absolute  trajectory  of  a particle runs from its entry point (7) into a cell (6) up to its exit point (8)  therefrom in a virtually recti-linear fashion, whereby in the scavenging process the mixing zone between the two media participating in the compression-wave process, and thus the scavenging losses, are greatly reduced by comparison with straight cells.

Inventor: IKENO MOTOKIYO
IPC: G06F9/46
Filed: 1990-03-02
Abstract: In a multiprocessor system, a request from a processor for data transfer between an external mass storage unit and a main memory is granted and a report indicating an event is supplied from the external storage unit if there is one to report.  An event decoder decodes the reported event and makes a first decision if it is a sync-related event resulting from the execution of an instruction and makes a second decision if it is a sync-unrelated event irrelevant to execution of instructions.  One of the processors except for the granted processor is selected as a master processor to be interrupted when a sync-unrelated event occurs.  An interrupt generator supplies an interrupt to the request-granted processor when the first decision is made by the decoder or supplies it to the selected master processor if the second decision is made.  When an event such as overvoltages and high temperatures occur during data transfer, the processor requesting such transfer is prevented from being indiscriminately interrupted.

Title: Erasure arrangement for an error correction decoder
Inventor: ERYAMAN CAN A
IPC: H03M13/45
Filed: 1990-03-30
Abstract: Abstract of the Disclosure In a decoder receiving error correction coded messages comprising forward error correction symbols including phase shift keyed type signals, each block of received symbols is processed to determine the energy of the component phase shift keyed type signals of each symbol and the average energy of the symbol. The component signal energy of the symbol is compared to a first prescribed threshold and symbols having energy values below the first threshold are marked.the average symbol energy is compared to a second prescribed threshold. Symbols having average energy below the prescribed second threshold are chosen and stored in order of increasing energy. Error positions are selected from the marked and chosen symbols in increasing energy order until a prescribed number is reached.

Patent CA-2021453-A1 (CA)
IPC: D07B7/14
Filed: 1990-07-18
Abstract: An improved method is provided herein for sheathing a defined length of a pitched cable with a layer of plastic.          In the improved method, the outside diameter of the defined length of cable is first reduced to a smaller diameter, and a plastic pipe is drawn onto this length of reduced diam-eter.  Then, by applying an external force to reduce the outside diameter of this plastic pipe, the pipe is fixed in such a way on the pitched cable that at least part of the inner wall of the plastic pipe protrudes into the space between the turns in the pitch elements.   The outside diameter of the defined length of the pitch elements may be reduced by grinding the outside diameter smoothly down or by hammering or rolling so that, as a result of this reduc-tion in diameter, no compaction occurs in the material of which the pitch helix or carrier cable is made.

Title: Slot antenna having controllable polarization
IPC: H01Q21/08
Filed: 1990-10-12
Abstract: An antenna incorporating a slot and a plurality of ear-like dipole elements. The antenna comprises a ground plane having a slot disposed therein, and a plurali-ty of ear-like elements attached to one side of the ground plane along the elongated edges of the slot. The ear-like elements are oriented orthogonal to the ground plane in the same direction. Typically, the plurality of ear-like elements are disposed in a symmetrically opposed relationship along the elongated edges of the slot. The plu-rality of ear-like elements typically comprise two generally quadrant-shaped ele-ments having the centers of the respective quadrant-shaped elements are disposedat or near the outer edges of the slot and the outer edge of the elements extend to about the middle of the slot. The ear-like elements may be rotated with respect to the slot in order to fine tune the polariaation direction. In a typical antenna, a plu-rality of slots are employed, and the present invention permits the use of randomly oriented or regularly spaced slots that are fed by means of conventional rectangular waveguides or boxed stripline. An polarized radiation field having a controlled ar-bitrary polarization is selectively produced by controlling the relative positions of the slot and ear-like elements. Typically, if all the energy radiates from the ear-like elements, then the antenna is polarized along the slot. If all the energy radiates from the slot, then the antenna is polarized across the slot. When both the slot and ear-like elements radiate energy, then the antenna is linearly polarized if both the slot and ear-like elements radiate in phase, circularly polarized if both the slot and ear-like elements radiate with equal amplitude and the phase difference between them is ?90 degrees, and elliptically polarized if the excitation amplitude and phase associated with the slot and ear-like elements are not the same.

Title: Monopole, dipole, and quadrupole borehole seismic transducers
Inventor: OWEN THOMAS E
IPC: G01V1/40
Filed: 1991-01-03
Abstract: ABSTRACT   Various configurations of cylindrically shaped transducers (10), (160), and (190) are used as borehole seismic wave sources. The basic class of transducers of this invention has an outer shell (12) that is generally cylindrical, and may be comprised of cylindrical sections (162) and (164); (192a), (192b), (194a), and (194b). The shell (12) or the sections (162) and (164); (192a), (192b), (194a) and (194b), may be pre-stressed or preformed to encourage certain bending motions. Depending on the configuration of the transducer, it approximates a monopole(10),dipole(160), or quadrupole(190)radiator. Various actuating means (132), (142), and (152), including magnetostrictive forces and piezoelectric forces, are used to drive the motions of the transducers (10), (160), and (190). These transducers (10), (160), and (190) are especially useful for generating compressional, shear, or other elastic waves in solids. For example, in geophysical applications, the transducers are placed in boreholes for either hole-to-hole or single hole measurements.

IPC: B29C48/09
Filed: 1991-01-17
Abstract: A  continuous  process  and  apparatus  for  forming products  from thermoplastic materials  between  top  and bottom mold carriages is disclosed.  Each carriage has a frame  including  a  backup  plate  coated  with  a  low coefficient  of  friction material  over  which  slides  a continuously moving belt mold.  The belt mold is comprised of a flexible silicone rubber mold adhered to a fiber belt.          The silicone rubber mold has a surface of desired shape for mating with an opposed mold surface to form a continuously moving  mold  channel  into  which  is  fed  thermoplastic material at a moldable temperature.  After molding the hot plastic material, localized surface heat of the belt molds is removed by cold air blown against the belt mold.  The low coefficient of friction backup plates have numerous air-bearing holes for feeding high pressure air between the low coefficient of friction plates and the moving fiber belt to reduce friction and reduce wear.  The fiber belts are guided and driven by a wide V-shaped central ridge or by twin-wide V-shaped ridges near their edges.   The V-shaped ridges fit into and mesh with corresponding geared teeth in grooves of the sprocket drive rolls and operate to maintain alignment of the mold belts. An electric drive motor, with or without the assistance of a torque motor, drives both belt molds in unison to maintain their relative alignment.  Electric screw jacks raise the top carriage, extend and retract the grooved exit rolls, and fine tune the alignment of the moving belt molds by adjusting the grooved exit rolls and move the machine to and from the extruder.
