Title: Improvements relating to electrical inverters
IPC: H02M7/515
Filed: 1964-09-17
Abstract: In a static inverter 4 for supplying several fluorescent lamps, the output transformer TR3 has tertiary windings P4, P6, connected to the D.C. supply through diodes D7 and D6 respectively to provide current feedback from the output to the supply and thereby improve the output regulation and the inverter efficiency. The primary winding P1 of the output transformer is centre-tapped as at PT, and the tertiary windings P4 and P6 are connected to tappings P3 and P5 at, for example, 90% from PT. The tertiary windings are wound in bifilar fashion, as are the pairs of windings PT-P3, P5-PT and P3-P1, P5-P2. The inverter switching elements comprise a pair of SCR's, SCR1, SCR2 which are commutated by a capacitor C4 and triggered alternately. The trigger pulses are generated by an oscillator 2, amplified and shaped by a push-pull amplifier 3, and fed through diodes D2 and D3 to the SCR gates. Voltage spikes and ripple on the D.C. supply 1 are reduced by a silicon carbide resistor MET and a smoothing circuit D1, Cl respectively. Each of the SCR's may be replaced by a parallel combination of SCR's.

Title: Process for the continuous preparation of vinyl acetate
IPC: B01J31/00
Filed: 1967-11-11
Abstract: Vinyl acetate is prepared by reacting ethylene with acetic acid and oxygen in the gaseous phase at an elevated temperature in the presence of a catalyst containing palladium metal and one or more alkali metal salts, e.g. acetates or compounds which can form alkali metal acetates under the reaction conditions. The process is continuous and a small quantity of one or more alkali metal salts is added continuously or intermittently to one or more of the reactants so that the composition of the palladium carrier catalyst (i.e. noble metal, alkali metal acetate and carrier) is kept constant and optimal. The addition of the alkali metal compound preferably in the form of a solution, to the reactant or reactants may be accomplished by passing the latter partly or entirely in the gaseous form through a solution of alkali metal compound or through layers of solid bodies impregnated with alkali metal compounds.

Title: Treatment of steel
IPC: C22C38/00
Filed: 1967-11-22
Abstract: A steel having high strength and elongation is formed by subjecting an austenitic steel, having M s and M D below ambient temperature, 0À2-0À5% C plus N, and at least 0À5% of at least one element selected from Mo, Cr, Mn, V, Nb, Ta, W, to deformation above 650 F. but below its recrystallization temperature. In one example, stainless steel is heated at 2080 F. for one hour, cooled to 840 F. and rolled, e.g. 20%, 80%, after which it is quenched to room temperature. Alternatively the steel may be quenched from 2080 F. to room temperature, reheated to 840 F. and rolled 80% to form a steel having an elongation of 40% and a yield strength of 222,500 p.s.i. This steel may be further strained 15% at room temperature and finally heated at 840 F. for 30 minutes resulting in an elongation of 25% and a yield strength of 273,000 p.s.i. In another example, the steel is cooled after deformation to liquid nitrogen temperature, strained below ambient temperature and tempered above room temperature.

Patent ES-372644-A1 (ES)
Title: Television synchronizing pulse separator
IPC: H04N5/08
Filed: 1969-10-17
Abstract: A sync. separator comprises an amplitude limiter employing a transistor the collector electrode of which is coupled to the output terminal of the separator and is also coupled to a supply source by a resistor, the base electrode is coupled to the junction of a capacitor and a leakage resistor forming a time constant circuit, and the emitter electrode is connected to the input terminal of the separator through an ohmic resistor. A negative modulation carrier signal 5 is detected by diode 7 and applied to an emitter follower 10 biased by a voltage source Vo. The resulting signal 12 is applied to an AGC circuit 15, to a terminal 13 which may be connected to a video amplifier, and to the sync. separator which comprises a transistor 17 in the common base configuration. The base of transistor 17 is biased from a voltage source Vo by means of a resistor 19 and a capacitor 18. During the line sync. pulses transistor 17 conducts and capacitor 18 is discharged through resistor 21 with a short time constant, and during the picture interval transistor 17 is cut off and capacitor 18 charges through resistor 19 with a long time constant. The voltage 26 on capacitor 18 therefore follows the peak negative level of the signal and the output at the collector of transistor 17 comprises the separated sync. pulses which are then inverted, amplified and limited by transistor 22 to equalize their amplitudes. When field sync. pulses occur capacitor 18 discharges to a voltage somewhat more positive than the peak sync. level due to the action of the potential divider constituted by resistors 20 and 21 so that during these long pulses noise voltages on the peaks of the sync. pulses are removed. An interference limiter may be included to prevent operation of the sync. separator during impulse noise.

Title: Sliding clasp fastener stringers
IPC: A44B19/40
Filed: 1970-06-03
Abstract: A method of making a sliding clasp fastener stringer comprises locating a series 22 of coupling elements by means of a tubular guide 24 adjacent a longitudinal edge of a carrier tape as it is warp knitted, and knitting in the tape at least one yarn 20e which passes at least partially around the series 22 and interlinks with the other tape yarns 20 to secure the coupling elements. A warp knitting machine for this purpose comprises five yarn guides 12 movable in a controlled manner by guide bars 13 reciprocably mounted in supports 14 secured to a bracket 15 which is keyed to a shaft 16 and oscillated about axis 17 by a crank 18. A row of latch needles 11 are slidably mounted in a trickplate 10 and the lower end of the tubular guide 24 through which the series of coupling elements are fed, e.g. by a ratchet-operated wheel, is located adjacent a longitudinal edge of the tape 21 being knitted and can be reciprocated between two needles 11 (Fig. 6) to assume the position shown in Fig. 4. The swinging movement of the guide 24 is achieved by means of yarn guide 12d. The fabric of the tape is knitted by yarns 20 and the yarn 20e is guided by the yarn guide 12e which is reciprocated through the row of needles together with the tubular guide 24 and laps the needles adjacent the tubular guide when in the position of Fig. 4. With the yarn guide 12e in its displaced lateral position (Fig. 6) the tubular guide 24 and yarn guide 12e are returned to the position of Fig. 1 which loops the yarn 20e about the guide 24 when the needles 11 are then moved downwardly and upwardly to knit one course during which the yarn 20e is drawn from the lower end of guide 24 to encompass the series of coupling elements between two interlocking heads. Typically the lapping of the yarn 20e may be arranged such that three courses of the tape are knitted to each pitch of the coupling elements with the yarn 20e lapping the tubular guide twice in every three courses so that two loops encompass each coupling element. In a second embodiment the tubular guide is retained in a fixed position and a yarn guide is reciprocated such that it loops the yarn around adjacent needles to secure the coupling elements.
