Title: Digital firing technique
IPC: H02P7/292
Filed: 1971-04-19
Abstract: 1338678 Automatic control of speed GENERAL ELECTRIC CO 19 April 1971 [5 Feb 1970] 20747/71 Heading G3R In a digital control system for controlling the output of power from a 3-phase A.C. power source 1, Fig.1, to a D.C. motor 2, oppositely poled thyristors or SCR's 3 (a-c) 4 (a-c) are selectively fired with a controlled phase delay and reversible preset counters (30) Fig.4 (not shown) in the firing circuits 5 (a-c) are repeatedly loaded at an appropriate point in each half cycle to a maximum positive or negative (two's complement) setting according to signals from a phase detection logic unit 9. The firing circuits 5 (a-c) contain parallel digital comparators (60) Fig. 6 (not shown) which compare the signals from a digital error generator 7 with the registers of the counters (30) which are set to count up or down according to the phase detected, the comparators giving a signal to fire the relevant thyristor 3 (a-c), 4 (a-c). Signals from the error generator 7 are obtained by comparison of signals from a command generator 6 and a feed back device 8 driven from the controlled motor 2. The counting is performed by pulses from a clock generator 13 as described in Specification 1338677 but the control system differs from that described with reference to Fig. 1 of that application in that comparators (60) are used in the firing circuits 5 (a-c) and the reversible counters (30) Fig.4 (not shown) are continuously monitored in a parallel system particularly suited to digital servo systems operating under highly transient conditions. The system is otherwise similar to that described in the Specification 1338677 and includes inhibited NAND gates (61), (62), Fig.6 (not shown) which prevent any erratic firing of the thyristors, SCR's etc. resulting from a noise signal when the preset numbers are loaded into the reversible counters (30).

Filed: 1954-07-16
Abstract: 752,040. Piezo-electric crystals. ELECTRIC MACHINERY MFG. CO. July 16, 1954 [July 20, 1953], No. 20763/54. Class 40 (8). A bender-type transducer comprises elements 11, 12 of barium or strontium titanate or a mixture thereof or barium zirconate joined together by a layer 13 of thermosetting resin. The element 11 has electrodes 14, 15 and the element 12 comb-like electrodes 18a, 18b so arranged that a source of potential 20 creates a voltage gradient across the element 11, and parallel to the length of the element 12. Thus the length of the strip 11 decreases while that of the strip 12 increases producing a large deflection in the transducer. In a modification, Fig. 5, a second series of transverse electrodes 25a, 25b are formed on the element 12, and are connected to electrodes 18. This arrangement produces a stronger voltage gradient parallel to the length of the element 12. In a further modification, Fig. 7, a strip of brass 30 is placed between the elements in electrical contact with the electrodes on each element. The potential may thus be applied between strip 30 and electrode 14 and between strip 30 and electrodes 18a, 18b.

In an interference-suppressing capacitor comprising two electrode strips folded or wound together and having connections made at opposite edges of both strips to permit the electrodes to be connected in series with the conductors of a circuit carrying interference currents, the capacitor is provided with self-healing properties by making one electrode in the form of a metallized layer upon a dielectric strip, the other electrode comprising a metal foil which is narrower than the dielectric strip, at least where connection is made to the metallized layer. Fig. 4 illustrates a wound capacitor comprising terminals 17, 18 connected to the metallized layer and terminals 13, 14 connected to the metal foil, two terminals being provided to increase the current-carrying capacity of the capacitor. The metallizing on the dielectric strip extends to the edges of the capacitor and connection thereto is made by means of sprayedon or vacuum-deposited metal coatings to which the terminals 17, 18 are soldered. The terminals 13, 14 each comprise metal tapes which are laid across the width of the capacitor and are insulated from connection with the metallizing at the edges of the capacitor by lacquer coatings or by pieces of insulating material wrapped around the tapes where they leave the capacitor roll. Fig. 5 shows a zig-zag folded capacitor comprising metal foil 20 and metallized dielectric strip 21, the area metallized being indicated by the broken lines. The metal foil 20 comprises projections 24 to which connection may be made. Connection to the other electrode is made by coating edges 25, 26 where the metallizing extends to the edge of the dielectric strip with metal and soldering thereto. Instead of the projections 24, metal tapes may be provided as in Fig. 4. Connection to the metallized layer in either embodiment may be provided by a conductive strip which is laid in as the capacitor is made; the conductive strip is preferably in the form of a metallized coating on an insulating tape to preserve the selfhealing properties of the capacitor. Capacitors according to the invention may be provided with two foil electrodes each for connection in one line of a circuit with a third metallized electrode for connection to earth.

Title: Process for the production of benzyl alcohol and benzaldehyde
IPC: C07C409/08
Filed: 1964-05-20
Abstract: Benzyl alcohol and benzaldehyde are obtained by oxidizing liquid toluene with a gas containing not more than 21% of oxygen at 170-220 DEG  C., the oxidation being discontinued when at most 10% of the toluene has been oxidized.  The primary oxidation product is benzyl hydroperoxide, and the oxidation may be effected in the presence of a peroxide stabilizer, e.g. sodium pyrophosphate or sodium fluoride. The hydroperoxide may then be decomposed after the oxidation, e.g. by catalytic hydrogenation or by heating it in an inert atmosphere to 180-280 DEG  C. or to a lower temperature if a deperoxidation catalyst is used, e.g. a cobalt salt or boric acid or the anhydride or an ester thereof.  The initial oxidation of the toluene, however, is effected in the absence of any metallic catalyst or peroxide initiator.  Examples are given.
