Patent AT-A312884-A (AT)
Inventor: STOCKINGER HELMUT ING
IPC: H04B5/00
Filed: 1984-10-03
Abstract: 1. Tunnel antenna system for wide-band signal transmission with a transmitter (S) at one tunnel end and a receiver (E) at the other tunnel end, which ends are connected with each other by means of a communication cable (NK) into which one or several coupling networks re connected, which networks serve, on the one hand, to feed the transmitter signals from the communication cable into associated transmitting antennae (SA) and, on the other hand, to feed signals, radiated in the tunnel and received via associated receiving antennae (EA), into the communication cable, in which case for the purpose of suppressing selfexcited oscillations the coupling attenuation between the transmitting and receiving antennae is greater than their transmission attenuation, characterised in that each coupling network has, in each case, a first amplifier (V1) which is connected into the communication cable (NK), serves to compensate the communication cable attenuation and at the output of which there is connected via a first coupling element (K1) a second amplifier (V2) with amplification which can be adjusted as a function of the degree of coupling between transmitting and receiving antenna, the output signal of the latter being coupled by means of a first signal distributor (S1) into the transmitting antenna (SA) and in that the signals received by the receiving antenna (EA) are coupled out of the receiving antenna (EA) by means of a second signal distributor (S2) and supplied by means of a second coupling element (K2) to the input of the first amplifier (V1) and in that the adjusted amplification of the second amplifier (V2) together with the given amplification of the first amplifier (V1) reduces the circuit attenuation of the coupling network, mainly determined by the coupling attenuation between transmitting (SA) and receiving antenna (EA), to a value which is greater than 20 dB.

Abstract: D.C. MOTOR CONTROL HAVING GATING CONTROL      OF A FULL-WAVE RECTIFIER SYSTEM  ABSTRACT OF THE DISCLOSURE A D.C. motor is selectively connected to receive ener-gizing power from a polyphase power source through a dual bridge rectifying system providing full-wave rectification and selec-tively operable to supply current of either polarity for motoring in either direction and regenerative operation.  An improved gating control system includes a plurality of gating channels each operative for supplying gating pulses to one of the recti-fying elements.  Each channel includes three cascaded  solid-state switching circuits operating in response to an analog output of a summing circuit receiving a compensated error signal, an alter-nating phase reference-signal, and a constant reference signal for properly controlling the firing angle of the associated con-trolled rectifier.  An input switching transistor circuit is connected to receive the analog output of the summing circuit and an output switching Darlington pair circuit selectively operates to operatively connect a storage capacitor to a primary winding of an output transformer having a secondary winding directly connected to the gating and cathode circuits of the controlled rectifier through insulated output leads.  An intermediate switching Darlington pair circuit is connected between the input and output switching circuits and provides an output circuit in one channel connected to an input circuit of an output switching circuit in another channel so that the two inter-related channels will both render the associated rectifying devices conductive to energize the D.C. motor.  Disable signals relating to the error signal polarity and the relative phase polarity are supplied to the input circuit of the intermediate switching circuit to disable the associated controlled rectifier.

Title: Methods for dtermining velocities and flow rates of fluids flowing in a well bore
Inventor: ANDERSON RONALD A
IPC: G01P21/02

Granted: 1978-10-24
Abstract: ABSTRACT OF THE DISCLOSURE     In the several representative embodiments of the new and improved methods discussed herein, a cable-suspended spinner-type flowmeter is successively lowered and raised at selected speeds in a well bore containing one or more flowing fluids whose velocity or flow rate are to be determined.  In one manner of practicing the invention, the flowmeter is passed back and forth trough a lower static well bore interval for establishing the  response of the tool at zero flow rates.  In this way the output measurements obtained from the runs through the higher or dynamic intervals can be  uniquely correlated for accurately determining the velocity and flow rate of the well bore fluids in each dynamic interval independently of differences in fluid viscosity.  In another manner of practicing the invention, output measurements obtained upon passing the flowmeter back and forth through a dynamic well bore zone in which the fluids are flowing at a known rate are used for accurately determining the velocity and flow rate in the other dynamic well bore intervals.

Abstract: DOUBLE DISC GATE VALVE WITH  ENTRAPPED STEM CONNECTION                          Abstract of the Disclosure A gate valve includes a pair of identically shaped tapered discs defining a tapered self-locking axially translatable gate wherein each disc has an annular hardened seating surface which engages the mating surfaces on the valve body adjacent the flow ports.  Tongues on the sides of the discs ride in vertical grooves on the valve body as the gate travels between a raised open and a lowered closed position.  The discs are separated by an annular spacer ring of substantially smaller diameter than the seating surfaces surrounding an interlocking segmented hub formed on the inner juxtaposed surfaces of the discs, the arrangement being such that the spacer ring can be sized to establish an overall gate width which will ensure that the seating surfaces are making proper sealing engagement with the valve seats with the diametral differences increasing the disc flexibility.  The spacer ring can be replaced by an appropriately sized spacer ring to compensate for thickness reduction in resurfacing the seating surfaces.  The discs of the gate are provided with a slot transverse to the flow ports which captures a T-head on the stem assembly, the slot being positioned in the gate interior radially within the seating contact area to thereby reduce the overall height of the valve.

Abstract: METHOD AND APPARATUS FOR REDUCING LATERAL FORCE VARIATIONS   AND OVERTURNING MOMENT VARIATIONS IN PNEUMATIC TIRES                 Abstract of the Disclosure A method and apparatus for reducing lateral force variations and overturning moment variations in pneumatic tires by detecting the magnitude, direction and location of such variations and alternatingly grinding off opposite por-tions of the two shoulders of the tire tread.  A tire is mounted on a test rim, inflated to operating pressure, and rotated under a normal service load against a loading drum.          Force variations in the lateral and radial directions are detected and measured by load cells operatively associated with the drum axle and located at opposite ends of the axle.          The sum of the lateral force variation forces or the dif-ference of the radial force variation forces measured by the load cells provides a voltage level signal representative of the direction, magnitude and location of the lateral force variation and the overturning moment variation.  The phase angle of this signal is ascertained to determine the loca-tion on the tire of these variations.  Where these variations exceed a preset level, they are reduced by alternatingly grinding a zone of one shoulder of the tire tread and the opposite zone of the other shoulder of the tire tread in response to the phase angle of the variation signals.  Re-duction of lateral force variations by this method also reduces radial force variation.
