Abstract: An indicia (12), for example a bar code, having a requirement for a high degree of precision is printed onto a sheet (14) and is scanned or read automatically shortly thereafter. Electronic control signals result from a comparison of the actually printed indicia (12) with a pre-defined quality standard, and are used selectively to adjust command control signals to the printer (10) to correct indicia printed thereafter. The leading edge of sheets (14) on which the indicia is to be printed is precisely located by a sensing mechanism (98) which controls a sheet advance motor (80). The bar code is read by an optical bar code scanner (100) traversing the printed code which is controlled by a scanner microprocessor control. The printer (10) is controlled by a printer microprocessor control (200) which controls a comparison of the scanned code with a set quality standard. Output signals are produced to control the printer microprocessor control in a feedback loop to increase or to decrease the time or voltage application to the printing elements in a thermal printer, thus correcting the'bar code

Abstract: A high-intensity X-ray source generates significant heat at the anode. To help dissipate this heat, the anode is often rotated in the vacuum. Heat must still be radiated from the anode to the exterior walls. An improved X-ray source incorporates the anode in the walls of the vacuum chamber and rotates the entire chamber. The heat is then easily conducted to the exterior where it may be dissipated by connection or forced air cooling.

Abstract: An electronic apparatus supplied by a battery and switchable by a push-button switch is described which is immediately ready for use again, without operating a switching key, following a brief failure of the battery voltage (UA). The electronic apparatus has a first push-button switch (10) which closes a charging circuit for a capacitor (22) supplied by the battery voltage when it is operated briefly. As soon as the capacitor is at least partially charged, the capacitor voltage triggers the excitation of a relay (32). When the relay is excited, a switch (34) controlled by the relay is closed, making a connection between the battery and a supply voltage terminal (35) for the electrical circuit (36) of the electronic apparatus. When the first push-button switch (10) is released, a latching circuit (31, 12, 13) for the relay comes into effect. A second push-button switch (30) forms an off switch. On operating this push-button switch, a circuit which discharges the capacitor (22) is closed. In this way, power is removed from the relay (32) and the switch (34) is opened so that the supply voltage for the electrical circuit (36) is switched off. (Figure). <IMAGE>

Abstract: The apparatus increases the hydraulic pressure in rams 16 until one pipe moves towards a heater plate 14. The movement is detected by a limit switch 26 and a micro processor-based control system 28 adds a pre-programmed value of pressure to that pressure which caused the movement (drag pressure). The total pressure is applied to force the pipe ends against a heater plate 14 to form end beads (bead-up). After heating for a pre-programmed period the control system automatically initiates plate retraction and forces the pipe ends together (fusion) for another programmed period. The applied pressure is the sum of the recorded drag pressure and a pre-programmed added pressure. Operator judgement of bead size, pressures and time periods is eliminated. Pressurised fluid is supplied to the rams 16 from a pump and accumulator combination. The sense of ram motion is determined by changeover valves controlled by the control system 28.

Abstract: Nucleons which are chemically bound to oil and water in geological formations posses magnetic moments which align in the earth's magnetic field causing the natural nuclear paramagnetism of the formation. An A.C. magnetic field at the Larmor frequency is repetitively applied to the formation adjacent to a borehole resulting in repetitive excitation-relaxation process of the nucleons present within an "excitation zone" which results in an amplitude modulation of the paramagnetism within this zone. This physical process results in an amplitude modulation of the < earth's magnetic field in the vicinity of the excitation zone of the formation and is called the Paramagnetic Logging Effect (PLE). 
     The PLE may be measured with logging tools in lopen holes and within cased well bores. The PLE measures the following quantities within a predetermined excitation zone of the formation: amount of oil, amount of water, total fluid volume, the viscosity of oil present, oil saturation and water saturation factors, estimations of the permeability, positions of vertical oil and water boundaries adjacent to the borehole, and the locations of lateral discontinuities of the oil bearing formation. The PLE is sensitive to such parameters at least 10 feet laterally into formation and up to perhaps 100 feet radially away from the drill hole. A thorough theoretical description of the PLE in open holes and in the cased hole environment is presented along with the detailed engineering data necessary for the construction of practical tools. 
     Another variety of the PLE is based on the repetitive excitation-relaxation process of natural electronic paramagnetic impurities found within petroleum. Measurement of the presence of such impurities indicate the presence of petroleum in formation.

Abstract: Internal stress on an object being electroplated is monitored continuously with a gauge. The gauge includes a metal receptor which is employed as a second cathode in the electrodeposition process. A separate plating current is supplied between the anode and second cathode, distinct from the separately controllable current between the anode and object being plated or electroformed. The stress on the second cathode is measured with a strain gauge, and a stress deviation from a desired plating stress is determined. The currents between the anode and first and second cathodes are adjusted in accordance with the measured internal stress on the metal receptor to achieve a desired stress condition. 
     The internal stress is advantageously monitored with a foil resistance strain gauge. The strain gauge is connected to a carrier disposed in parallel with the metal receptor. The carrier is rigidly connected at opposite ends to the metal receptor. A stress transmission link centrally located between ends of the metal receptor and the carrier transmits the force applied by the electroplating material on the receptor to the carrier. The strain gauge provides an indication of the stress which results from the electroplating. The currents between the anode and first and second cathodes may be controlled in accordance with this stress measurement.

Abstract: In a transmission system, adding and/or dropping any one or more of a plurality of digital signals of one or more digital transmission bit rates is facilitated by employing a un- lque transmission signal in which data words associated with Individual digital signals are arranged in prescribed groups. The transmission signal data word groups are obtained by formatting the individual digital signals to be combined into a unique channel frame format common to all of the digital signals and by employing a unique one-step multiplexing process to insert digital words from the channel frames into the group of data word positions in the transmission signal associated with the particular signal being combined. Consequently, digital signals may be added to the transmission signal by formatting them into the common channel frame format and, then, inserting the digital words therefrom in the one-step multiplexing process into an associated group of data words positions in the transmission signal. Digital signals are dropped from the transmission signal by extracting associated groups of data words from the transmission signal, identifying the corresponding channel frames and deformatting the data bits from channel frames of corresponding digital signals being reconstructed.

Abstract: A half-tone display system for a flat matrix type CRT, in which, in displaying video signals such as television signals, half-tone display of n gradations is effected for one field, the one-field scanning signal frequency is made m times as high, and the data signal is made to perform the half-tone display of n/m gradations during a 1/m field period. With such a half-tone display system, the scanning frequency is made different from an AC drive source's frequency, and therefore the displayed picture is free from undesired beat interference or flickering phenomonon. Thus, the displayed picture is steady at all times.
