Abstract: ABSTRACT OF THE DISCLOSURE           A  device  and a method for reducing power  consumption and correspondingly reducing lumen output of a phosphor excitable lamp,  such as a fluorescent lamp, connected to a source of power for  operation  of  the same,  without any  appreciable  loss  of operating  efficiency.    A  load  limiting  arrangement,   often referred  to  as  a  load  limiting  control  device,  and  which generally   includes  a  capacitive  element   is   electrically connectable to one terminal of the phosphor excitable lamp.  This device,  when  connected,  is effectively electrically interposed between the lamp and the source of power in a series  connection.  The  capacitive  element is selected with a capacitive  value  so that  the lumen output is reduced but with substantially  uniform lumen  output  at the reduced level and the power consumption  is reduced  without substantially changing the voltage to  the  lamp and   without  any  appreciable  effects  on  the  efficiency  of operation  of the lamp or the source  of  power.   Further  when sing  the  device  and method,  a circuit path  is  not  created directly  between the conductive terminal of the socket and  the end  terminal  of the lamp,  but rather  through  the  capacitive element to thereby reduce the power consumption and lumen output. n addition the load limiting arrangement may adopt the form of a capacitive  - indictive  circuit  arrangement.   In  a  preferred embodiment,  the device is constructed so that conductive pins on the  device is inserted in the pin receptacles of the fixture and pin receptacles on the device are offset to receive the  pins  on the lamp.

Abstract: D-23,772 POWER SUPPLY CONTROL CIRCUIT FOR                   SUBSCRIBER CARRIER TELEPHONE SYSTEM by James A. Stewart Abstract of Disclosure A control circuit that is responsive to voltage conditions on a cable pair transmission line for selectively disabling a battery charging circuit operating off of line current comprises a resistor and storage capacitor C2 connected in series across the line; a timing capacitor C1 connected between the cathode of a PUT (programmable unijunction transis-tor) and one wire of the line; and a zener diode between the PUT anode and one wire for establishing a conduction threshold for the PUT.  The resistor and primary conduction path of a first bipolar transistor, hav-ing its base connected to the PUT anode, are connected in series between the other wire of the line and the charging circuit so that startup our-rent for the latter may be used for charging C2 when the charging circuit is disabled.  Means is also included for driving the PUT gate voltage low and turning on the PUT in response to both high and low voltage condi-tions on the line.  This dumps the C2 charge into C1, which discharges slowly for holding the charging circuit disabled.  A second bipolar tran-sistor senses the charge voltage on C1 for decreasing the PUT gate vol-tage when the PUT conducts and for increasing it immediately prior to enabling the charging circuit to draw line current in order to prevent on-off cycling of the latter on a long cable pair.

Abstract: PROCESS FOR COAL-GASIFICATION AND        MAKING PIG IRON AND APPARATUS THEREFORE     ABSTRACT OF THE DISCLOSURE     In a melting/gasifying furnace including a coke-filled layer, coal is gasified by oxygen blown through tuyeres into a hot reducing gas which is caused to ascend through the coke-filled layer so as to melt reduced iron supported on the top of the coke-filled layer.  The resulting molten iron flows down through the coke-filled layer, and is collected in the lowermost region of the coke-filled layer and discharged therefrom, while the hot gas is recovered.  The thus recovered gas is fed into a shaft reduction furnace to reduce iron ores, and the thus formed reduced iron is supplied into the melting/gasifying furnace.          In addition to the coal, a variety of fuels mainly comprising carbon and hydrogen such as heavy oil, natural gas, etch are used for gasification.  The fuel is blown through the tuyeres and/ or charged through middle openings disposed above the tuyeres.

Abstract: Inventors:     Eugene J. Martin and Thomas Rollins Title: "Fluid Pressure Actuator With Stroke End Lock Mechanism"     ABSTRACT OF THE DISCLOSURE A fluid pressure actuator includes a lock mechanism for locking the actuator against movement in one end position, and an external lock release lever engageable with an external extension of the lock mechanism for releasing same. The lock release lever is engageable by a lock piston upon application of system pressure thereto to release the lock mechanism. During movement of the lock piston in the unlocking direction, and after disengagement of the lock mechanism, system pressure is ported through the lock piston both to the extend side of the actuator and the opposite end of the lock piston. By using substantially the same size seals on the opposite pressurized side of the lock piston and external extension of the lock mechanism, any effect of fluid pressure acting on such external extension of the lock mechanism is substantially negated. Accordingly, the effective area of the lock piston acted upon by system pressure to release the lock mechanism will remain substantially constant both before and after system pressure is admitted to the extend side of the actuator, whereby the lock is effectively locked open and there is always substantially full flow to the extend side of the actuator despite fluctuations in the extend pressure.

Abstract: ABSTRACT OF THE DISCLOSURE         An analog carrier signal and its sidebands contain modulated information which is to be digitally encoded and processed.  Demodulation and digital encoding is accomplished in a single process by an analog-to-digital converter, which samples the analog signals in response to a sampling signal of a frequency which is less than twice the frequency of the highest frequency in the carrier and sidebands, but is at least twice the bandwidth of the band of frequencies containing the carrier signal and its information-bearing sidebands.          The analog signal samples are digitally encoded, producing digital information signals corresponding to baseband signal components.         When used in a television receiver to produce digital signal samples, the band of analog signals may include both sound and picture carriers and their audio and video information.  By controlling the phase and frequency of the analog carrier signal in relation to the color subcarrier signal, and deriving the sampling signal from the analog carrier, an ease in video signal demodulation is provided.

Abstract: STATIC RAM CELL Peter Cheng-Yu Chen Alex Au ABSTRACT      A static RAM cell (11) is constructed utilizing low resistivity positive and negative power supply leads-(13,14), thus eliminating the problem of instability of the data stored within the cell.  The negative power supply lead is formed of a first layer of low resistivity polycrystalline silicon/tantalum silicide, and the positive power supply lead is formed of a second layer of poly-crystalline silicon. By the use of a low resistivity negative power supply lead, the voltage drop on the negative power supply lead is substantially reduced as compared with prior art devices,  thereby providing during the read operation substantially equal voltages to the gates of the two bistable transistors of each cell, thus eliminating the problem of instability during reading.      Depletion load devices (11,12) are formed utilizing the layer of polycrystalline silicon as the source, drain and channel and the layer of polycrystalline silicon/ tantalum silicide as the gate.  In this manner, silicon area is not required to form the depletion load devices, thus minimizing cell size.

Abstract: ABSTRACT: Precision current-source arrangement.     A current-distribution circuit (1) supplies a plurality of substantially equal currents (i1, i2, i3 and i4) to a permutation circuit (13), which transfers these currents to outputs (18, 19, 20 and 21) in accordance with a cyclic permutation. The currents in these outputs exhibit a ripple caused by the inequality of the currents (i1, i2, i3 and i4). A detection circuit (30) detects the ripple component of the currents (i1, i2, i3 and i4) and applies this ripple component to the associated control circuit of the block of the control circuits (50). The relevant control currents (i1, i2, i3 and i4) is corrected in such way that the ripple component substantially eliminates.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to a method and apparatus in a telecommunication system for activating means from an idle state to an active state.  Activation may take place either from the subscriber side or from the station side.  In acti-vation from the subscriber side an activation request signal is sent from a subscriber to the code transmitter in the net-work terminal.  The code transmitter sends a continuous cyclic bit pattern to the line terminal, in which the pattern is detected in the code receiver, and the activation request is sent to said station which then sends the activation order to the line terminal.  The frame code generator  is  activated and sends frame-formatted data  and synchronizing signal back again to the network terminal.   The local clock in the net-work terminal is synchronized conventionally with the rate from the master clock from the incoming data flow.  After detecting frame format and frame synchronism, the frame de-tector sends the activation order to the subscriber and furthermore activates said frame code generator for transmis-sion of frame formatted data back again to the line terminal. The information is detected in the latter in a second frame detector which, for discovered frame format and frame syn-chronism, sends acknowledgement signals to the station, whereat the activation sequence is completed.  In activation from the station side, the activation order goes directly from the station without a preceding activation request from the subscriber.
