Title: Oxidation of hydrocarbons and alcohols
Inventor: HOOPER GEORGE WALLACE
IPC: C07C29/48
Filed: 1962-06-21
Abstract: A process of oxidation of an aromatic, cycloaliphatic or olefinic hydrocarbon to give a phenol, alcohol or glycol respectively, or of an alcohol to give an aldehyde or ketone comprises contacting the hydrocarbon or the alcohol with a crude hydrogen peroxide solution produced by contacting hydrogen and oxygen in the presence of liquid water and an acid with a solid catalyst, the catalyst being capable of promoting the combination of hydrogen and oxygen to give hydrogen peroxide.  The catalyst may, for example, comprise at least one element from Group Ib and/or Group VIII of the Periodic Table and a carrier.  In a preferred embodiment of the process, hydrogen and oxygen are passed into an acidic water-containing liquid phase containing said catalyst and the organic compound which is to be oxidized. The decomposition of the hydrogen peroxide may be promoted by homogeneous catalysis or by radiation. Examples are given.

Fuel under pressure enters conduit 30 and passes through filter 31, opening 32 into chamber 34 and through a mixture control and shut-off plate 38 into passage 40 and thence through a passage 44 in valve member 46 which contains metering restriction 48 and through an idle mixture control plate 50 to passage 52 and valve assembly 54. Passage 52 communicates with the inlet port of fuel distributer 12 which divides fuel flow into equal increments each increment being discharged through an outlet port 62 and passage 64 leading to a fuel injection nozzle 66. The mixture control plate 38 is rotated by lever 80 connected to shaft 78 and the idle control plate 50 is rotated by a lever 92 connected to shaft 90, which is interconnected through an adjustable linkage 108 and lever 28 with shaft 26 carrying air throttle 24. Fuel flow through valve assembly 54 is controlled by ball valve 118 controlled by diaphragms 128, 140 which are interconnected by a pin 150 passing through a fluid seal 137. Diaphragm 140 responds to air impact pressure and Venturi throat pressure in chambers 160 and 162 respectively and diaphragm 128 responds to metered fuel pressure in passage 52 and unmetered fuel pressure in chamber 165 which communicates with chamber 34 via passage 166, port 168, passage 170, and opening 172 in mixture control plate 38. In fuel distributer 12, fuel under pressure from the inlet port communicates through passage 212 with chamber 190 and through passage 210 with the underside of spring-loaded diaphragm 196 which is subjected to ambient air pressure on its upper side. Fuel passes through bore 214 and through radial passages 216 into an annular recess 218 which is partly of constant radial depth and partly tapered. Increasing fuel pressure causes valve member 194 to rise so that recess 218 communicates with slots 186, the effective flow area increasing until the pressure drop across the distributer is subtsantially zero. In modificationsthe annular recess has a constant radial depth and the slots 186 are of modified shapes.

Filed: 1967-09-27
Abstract: 1,197,733. Associative stores. TEAC CORP. and RESEARCH DEVELOPMENT CORP. OF JAPAN. 27 Sept., 1967 [30 Sept., 1966], No. 44001/67. Heading G4C. A magnetic information retrieval system determines whether a search logic command specified by a matrix panel is satisfied by the relation between data from a tape and information specified by a matrix panel, and if so occurrence of a command causes comment information accompanying the data on the tape to be stored in a buffer. Each block of information on a magnetic tape consists of a series of parallel bytes, each accompanied by a clock signal and a parity bit in respective tracks, the bytes being in order: a start byte, a plurality of data bytes, a plurality of comment bytes and a terminal byte. Every third block is followed by a gap. A plugboard enables a search tag and search criterion to be set for each data byte of a block, the search criterion for a given byte also applying to any succeeding bytes for which no criterion is specified until a byte is reached for which a criterion is specified. The plugboard also enables a memory command to be associated with any comment byte position. The data bytes in a block are compared with the corresponding search tags and if in each case the result of the comparison indicates that the corresponding search criterion is satisfied occurrence of a memory command at a comment byte position will cause the comment bytes of the block, starting at that position, to be gated to a buffer store. If the buffer receives any comment bytes during a given sequence of three blocks the tape is stopped in the gap following the three blocks and the buffer contents are printed out. The possible search criteria are: (a) " coincidence " viz. equality; (b) " exclusive of coincidence " viz. inequality; (c) " part " viz. each bit position which is 0 in the search tag is also 0 in the data byte; (d) "inclusion " viz. each bit position which is 1 in the search tag is also 1 in the data byte; (e) "common possession " viz. there is at least one bit position which is 1 in both the search tag and the data byte; (f) " non-common possession " viz. the denial of (e); (g) " passage " viz. the search criterion is to be taken as satisfied irrespective of the relationship between the search tag and data byte.

[ Also in Division H3B] A capacitative switching arrangement comprises a glow-lamp relaxation oscillator including a capacitor probe, and having its output connected through a normally balanced R. C. network to a switching transistor controlling relay. Operation of the relay energizes a servomotor and also suppresses the oscillator for a predetermined period up to e.g. 20 seconds. In Fig. 1, glow-lamp 10 and parallel capacitor 16 are A. C. energized at power frequency to oscillate at e.g. 4 kcs, and connected to a transistor switch pair 23, 32 through a network so that no effective signal is applied to the transistors, which are normally cut off by bias from diode 40 and capacitor 42. Variation of capacity at the probe electrode 12 unbalances the system so that signals from the oscillator cause transistors 23, 32 to conduct, partially discharging capacitor 42, and lowering the voltage across relay 35 which drops out to (i) disconnect the supply through resistor 17 to the oscillator, and (ii) energize motor 30. Capacitor 42 slowly recharges, depending on the time constants of the circuit to reset system. A modified circuit is illustrated in Fig. 2 (not shown) in which the glow-lamp oscillator has a series capacitor (48) and leak resistor, and is D. C. energized from diode (52).

One cam formation (27) may have a portion (27a) causing rapid lateral deflection of pin 25 when the slider reaches the second position such that the resistance provides "feel" to locate this position, which is held by pin 26 and cam (28). After being latched in the third position further pressure on button 21 releases pin 25 from cam (27) but the pin 26 is guided by a rib (33) to re-enter its cam (28) and retain the switch in its second position until button 21 is again depressed; thus the switch cannot be directly restored from the third position to the "off" position shown. In a modification (Fig. 4, not shown) a spring-loaded ball in slider 14 cooperates with a shoulder in body 11 to provide the "feel" for the second position.
