Title: Wide angle deflection system
IPC: H03K4/71
Filed: 1971-11-30
Abstract: Wide angle (e.g., 110 DEG ), large screen (e.g., 25 inch diagonal) color television display system employs a narrow-neck (e.g., 29 centimeter diameter) color kinescope with a deflection yoke having toroidal horizontal and vertical deflection windings. While power requirements of toroidal horizontal windings are met by a thyristor horizontal deflection circuit, toroidal vertical windings are driven by a transistor vertical output amplifier in a quasi-complementary symmetry, Class B, push-pull configuration. Capacitor is provided in negative feedback path between amplifier output and driver input, establishing Miller integrator action for linear sawtooth wave generation. Diode in series with capacitor provides voltage rise aiding rapid turn-on of driver at end of retrace interval. Oppositely poled diode shunting first diode completes low impedance capacitor discharge path during retrace interval.

Title: Method for reducing particulate metal ores to sponge iron with recycled reducing gas
IPC: C21B13/02
Filed: 1972-10-14
Abstract: A method and apparatus is disclosed for achieving improved reduction efficiency in the reduction of particulate metal ores, e.g., iron ore, in a vertical shaft, moving bed reactor having a reduction zone in which a hot reducing gas is caused to flow through a portion of the ore bed to reduce the metal ore thereof to metal, e.g., sponge iron. The improved efficiency is achieved by using a splitflow of reducing gas to the reduction zone of the reactor. In one embodiment of the invention separate reducing gas streams are supplied to the top and bottom of the reduction zone and combined near the center of the reduction zone and removed from the reactor. In another embodiment of the invention reducing gas is fed to a point near the center of the reduction zone, caused to flow both upwardly and downwardly through the ore in the reduction zone and removed at points near the top and bottom of the reduction zone. By using the disclosed split-flow systems, the residence time of the metal-bearing material within the reactor can be reduced and the productivity of the reactor thereby increased.

Patent ES-421871-A1 (ES)
Title: Balanced PCM encoder
IPC: G11C27/02
Filed: 1973-12-28
Abstract: This invention relates to the amplification circuitry, storage circuitry and encoding circuitry of a feedback comparison type PCM encoder. This circuitry incorporating a storage capacitor operates sequential on each analog signal sample of a plurality of such samples applied thereto in a TDM channel format. A balanced circuit arrangement incorporating differential amplifiers is employed for each of the above mentioned components of the PCM encoder. The capacitor is fed from the TDM input through a first gated differential amplifier. Then this amplifier is blocked by a second differential amplifier behaving as a variable impedance. The blocking of the first differential amplifier prevents leakage from the TDM input to a third differential amplifier which includes the storage capacitor. The charge of the capacitor, corresponding to the previous sample, is adjusted to each new sample at a constant current rate. Under this condition one capacitor terminal jumps towards the new potential impressed on that terminal and the other capacitor terminal moves linearly towards the new potential on the other terminal. A fourth differential amplifier is coupled across the capacitor and the output currents thereof are algebraically combined with the input currents derived from the previously coded sample by a digital-to-analog converter present in the feedback path of the encoder. The results of the algebraic addition of the two currents are provided as a balanced voltage input to a binary voltage comparator which provides the code representing the magnitude of the present sample.

Title: Spiral reinforcement thread in wall of extruded plastic tube - is introduced at a fixed station, as the extruded material spirals past
IPC: B29C48/09
Filed: 1977-09-08
Abstract: In contrast to known methods, the invention requires the material that is to form the spiral to be introduced at a fixed station, while the still-liq. material of the tube spirals past. Pref. the plastic is extruded into an annular channel formed between a fixed wall and a rotating peg. At a certain point the peg narrows, the channel correspondingly widening, and the stream of plastic divides into two. The outer part passes round a stationary ring that stands at this point, while the rest of the plastic passes through borings that perforate the ring. The reinforcing material is introduced at this point, between the two streams of molten plastic. The two streams re-unite as the peg that forms the core of the extrusion channel resumes its full dia.
