Granted: 1993-02-09
Abstract: APPARATUS AND METHOD FOR PERMANENTLY JOINING       PLASTIC SCREW CONVEYOR FLIGHTS                            ABSTRACT      Apparatus for bonding or joining confronting edges of flights of adjacent integrally molded screw conveyor modules is disclosed.   The apparatus comprises means for supporting a plurality of the modules in axial alignment and with confronting edges of the module flight members in confronting relationship.   Also included is a clamping means for enclosing and maintaining the confronting edges in a fixed position.   The clamping means includes at least one passage extending from outside the clamp to a position inside the clamp between the confronting edges.          A heated gas such as nitrogen is provided through the passage to the confronting edge to heat the edges substantially to the melting point of the plastic modules.  Subsequent to heating the edges with the hot gas, a liquid plastic material under selected temperature and pressure is injected  through  the  clamp  passage  and  into  the  space  between  the confronting flight edges to fill the space between the edges and to bond the flights together.

Abstract: ABSTRACT OF THE DISCLOSURE           Wellbores are cemented with a cement composition formed from drilling  fluid  occupying  the wellbore  by  circulating  a quantity of drilling fluid mixed with a cement material and a dispersant such as a sulfonated styrene copolymer with or without an organic acid into the wellbore to displace the drilling fluid and to continuously convert the drilling fluid into the cement composition.  The cement composition may be recirculated through the space in the wellbore to completely evacuate any drilling fluid not converted to cement so as to minimize any faults in the cement composition occupying the wellbore.  A preflush composi-tion containing the dispersant and being rheologoically compati-ble with both the drilling fluid and the drilling fluid converted to cement slurry may be used as a displacement fluid.

Granted: 1991-10-08
Abstract: FIELD ORIENTATION CONTROL OF A     PERMANENT MAGNET MOTOR            Abstract of the Disclosure A field orientation control system for an interior permanent magnet synchronous motor includes function generating means responsive to a torque command signal for producing direct and quadrature axis direct current signals which are converted to synchronously-varying two-phase signals for coupling to power control means, for effecting sinusoidal energization of the permanent magnet motor.  The function generators modify the torque command signal as a predetermined function of the motor parameters.  Rotor position information is derived from measured stator voltages and currents without the use of a separate rotor position sensor.  The control system includes means for establishing a preselected amplitude of stator .alpha.-axis current in the motor at start-up prior to establishing orthogonal .beta.-axis current such that the motor rotor is caused to become initially aligned with the selected .alpha.-axis.

Granted: 1993-05-11
Abstract: ABSTRACT      A burst error correction apparatus suitable for correcting burst error due to a bit slip in a self-clocking signal containing resync codes at predetermined intervals, e.g., a self-clocking signal read out from a digital recording medium before the signal is demodulated.  This apparatus has a shift register for receiving the self-clocking signal in series; a detector for detecting, an inhibited pat-tern which has not existed in the self-clocking signal in response to parallel outputs from a section in the vicinity of the entrance of the shift register; and a controller for shifting, by respectively controlling clocks applied to the shift register and a rear stage of the same, data appearing from a position in the vicinity of the inhibited code between adjacent resync codes to the subsequent one of these resync codes in accordance with the direction and the number of bits based on a detection signal from the detection means.  The apparatus enables data reading with improved accuracy even in a system inferior in accuracy by correcting burst error due to a bit slip in a self-clocking signal containing resync codes at predetermined intervals before this signal is demodulated, and also enables, with respect to a system improved in accuracy, a reduction in the number of redundant data items for error detection/correction.

Granted: 1992-07-28
Abstract: ABSTRACT          A phase adjusting circuit for adjusting the phase difference between at least two input data strings, supplied through respective input lines is described.  The circuit has a sync detector for generating first and second sync detection signals by detecting sync signals from the first and second input data strings.  A phase relation signal generator is responsive to the first and second sync detection signal to generate a phase relation signal representing the phase relation between the first and second input data strings.  A phase difference detector generates a phase difference signal indicative of the phase dif-ference between the first and second data strings.  A first switch is responsive to the phase relation signal to switch the first and second input data strings to produce first and second switched data strings.  A variable delay circuit is responsive to the phase difference signal to delay the second switched data string to produce a delayed data string.  A second switch is res-ponsive to the phase relation signal to deliver the delayed data string and the switched first data string to output lines corres-ponding to the input lines.

Title: Adjustable lens shield assembly for vehicular lights
Inventor: NEECE ROY M
IPC: B60Q1/26
Filed: 1989-09-28
Granted: 1991-03-12
Abstract: Abstract of the Disclosure A lens shield assembly and method for protecting recessed vehicular lights, such as the type mounted behind a cutout in an automotive body, from gravel, stone, and other roadway debris. The assembly includes an essentially transparent protective plate that is positionable against an outer vehicle surface (such as a bumper or fender) to cover a cutout behind which a light is recessed. A first retaining member is attachable or fixedly secured to the plate outer region and positioned through the opening in the vehicle surface to secure the plate to the vehicle surface. A clip attaches to an outer region of the plate for sliding engagement along an opening in the plate, and can be positioned against a portion of the vehicle surface which borders the cutout so as to clamp the vehicle surface between the plate and the clip. A fastener such as a screw passes through the plate opening for coupling the plate to the clip. According to the method, the plate is position-ed over the cutout so that the retaining member and clip each extend into the vehicle body member along the border of the cutout. With the retaining member positioned against a first edge portion of the cutout, the clip is moved along the plate opening against a second edge portion of the cutout and clamped against it in order to secure the plate against the vehicle body member. If desired, both the retaining member and the clip can be identi-cally formed and manipulated to secure the plate to the vehicle. The plate may be clear or colored.

Patent DK-158302-C (DK)
Inventor: SCHULZ ECKHARD
IPC: C04B40/02
Filed: 1984-07-13
Granted: 1990-10-01
Abstract: The method relates to the hardening of form substances made of building materials and containing binding agents in a pressure chamber of an autoclave to which is conveyed a gaseous heating medium, the temperature of which is increased during a heating-up phase up to a given upper limit value. During a holding phase, the temperature is maintained at least until a given equalization temperature is reached on the inside of the form substances. Subsequently, during a cooling-down phase, the temperature is reduced by reducing the pressure to the expulsion temperature. Porous light building materials in a conventional process would absorb a high amount of water through the condensation of water resulting from steam having been conveyed into the autoclave for the purpose of hardening. However, in order to produce form substances of a low water content economically, according to the present invention, on the one hand, steam is replaced by gas which is maintained below the evaporation temperature of water through sufficient increase in pressure, and, on the other hand, as a replacement or complement, heat is conveyed to the inside of the pressure chamber before the cooling-down phase and an increase in the temperature of the steam beyond the given limit value is prevented by blowing off steam, thereby attaining an integrated drying process.
