Abstract: ADAPTIVE COMPASS DRIVE RADAR SYSTEM                           Abstract A radar system having an adaptive compass drive capable of operation over a wide variety of compass outputs and supply voltages and frequencies.  For compass outputs in the form of multi-phased analog signals, a digital phase detector converts the signals to a series of digital pulses which are used to operate a three-phase to UP-DOWN pulse converter.  If the gyro compass output signals are in the form of overlapping digital signals, the converter changes the signals directly to a sequence of UP or DOWN pulses.  The UP-DOWN pulses are used to operate a binary counter which operates the phases of a multi-phased stepper motor which is coupled to the true bearing scale of the radar system the output of which may also be used to operate a north stabilization synchro converter for the radar display.

Abstract: Abstract A sensing circuit is placed in the tip line of a subscriber's loop to sense, selectively, the placement of an outgoing, local call.  The circuit includes a first LED for energizing a metering circuit upon detection of a billable call, and a second LED for latching the metering circuit in its energized condition within a predetermined interval after the billable call is detected.  The metering circuit is automatically deenergized when the called party goes on-hook. A balancing circuit is included in the ring line of the equip-ment to balance the impedance created in the tip line by the sensing circuit; and the metering circuit can be designed selectively to produce a one-shot metering pulse for each billable call, or to produce a continuous signal for the duration of the call.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a process for recovery of waste H2S04 and HCl which are used for pickling metallic materials and articles and contain   large quantities  of Fe ions.  Furthermore, it offers a process for recovery of H2S04 and HCl from waste H2S04 which contains large amounts of Fe ions after removal of Ti ions by hydrolysis process in the production of Ti02 and also high-purity electrolytic iron or iron hydroxide. In an oxidation reduction cell, Fe2+ ions in the waste, the waste constituting the anolyte, are converted to Fe3+ ions which are extracted from the anolyte with an organic solvent to recover HCl and H2S04. The solvent is then stripped with an HCl stripping solution to be regenerated, leaving an HCl stripping solution containing Fe3+ ions.  The Fe3+ ions are then recovered by liquid-liquid extraction with another organic solvent to form an FeC13 complex.  The second solvent is then regenerated, iron values are recovered and the HCl strip solu-tion is also regenerated.

Abstract: Abstract of the Disclosure A signaling arrangement for indicating to a remote location that coins in the cash receptacle of a coin-operated device have accumulated to a predetermined fill level is disclosed.  In particular, a coin telephone station is disclosed, which station has a tone oscillator connected to an associated central office by a telephone line.  The oscillator is controlled by a three-input logic gate.  One input of the gate is enabled by a coin probe when the coin box is filled to a predetermined level.          Another input of the logic gate is enabled by a flip-flop that is set when a coin collect potential is received by the station over the line.  The third input of the logic gate is enabled when talking battery is applied to the line.  The logic device thereupon operates the oscillator which generates a tone signal that is sent to the central office over the line, indicating to the office that the coin box is full.

Abstract: ABSTRACT OF THE DISCLOSURE          This invention discloses a novel cutting roller for chopping continuous elongated filaments into finite fibers of a predetermined length.  A plurality of spaced, axially parallel cutting blades are mounted on a driven roller drum and are held in receiving groove by retainer strips.  The peripheral flange surface of the cutting roller in the opposite ends of the roller drum are raised to almost the radius of the cutting blade edges and serve as driving engagement surfaces when the rotating cutting roller is braised into contact with a feed roller.  The problems of accelerated wear and deterioration of synthetic resin or rubber feed rollers of the prior art and damage to the edges of the cutting blades of the prior art devices have been successfully overcome.  Also, the device of the present invention allows two rollers to revolve at exactly equal circumferential speeds which has not been successful with the device of the prior art.

Abstract: ABSTRACT OF THE DISCLOSURE           A control system for a guided missile or projectile in which signals to compensate the steering commands of the guided missile or projectile for the effects of gravity are dynamically produced and stored while the missile or projectile is in flight. The system includes a gyroscope mounted in the missile or projectile for establishing an attitude reference axis independent of the attitude of the missile or projectile. Gravity compensa-tion signals are generated in response to sensed angular differences between the attitude of the missile or projectile and the reference axis, and the generated gravity compensation signals are stored. The missile or project-tive steering commands are then compensated for gravity effects by use of the stored gravity compensation signals during the guidance mode of opera-tion.

Abstract: ABSTRACT OF THE DISCLOSURE            The specification describes a method for starting up and low load operation of pressure fired boilers for example with a pressure firing system supplied from a pressurized coal gasification unit.  For starting up a heat storage device and a starting boiler are provided.  Starting up is carried out using hot water at a temperature of above 100° C. as for example 180° C. from a high pressure pre-heater supplied by the starting boiler.  Low load operation is carried out using forced circula-tion of the boiler feed water by means of a water trap.  Firstly, the boiler, its pre-heaters, and the evaporator of the hot storage means are filled with hot water until a medium water level has been reached in the water trap.  Following this, by-passing the direct return line into the boiler with the help of forced circulation the water from the water trap is circulated through the pre-heaters and the boiler and the circulated water is heated up with the starting boiler in the high pressure heater to the hot water temperature.  After achieving the latter the pressurized firing system is ignited and then circulation using the pre-heaters is interrupted and switched over to the direct return line.
