Title: Liquid phase oxidation of acetylenes
Inventor: RENNIE ROBERT ALLEN CAMPBELL
IPC: C07C45/30
Filed: 1965-02-04
Abstract: An a -dicarbonyl compound especially glyoxal is produced by oxidation of an acetylenic compound, preferably a hydrocarbon and especially acetylene, in aqueous medium by the reaction with a trivalent organophosphine, arsine, or stibine gold complex of the general formula R3YAuX3 where R is an organic group or, in the case of at most two of the R groups, hydrogen, Y is P, As or Sb, and X is Cl, Br or I. Preferred gold complexes contain P, and all the R groups are organic, especially aryl groups and X is chlorine.  After the oxidation the gold complex may be regenerated to the trivalent state with halogen, a halate or perhalate salt, or an oxidizing agent in the presence of halogen ions.  As gold complex regeneration oxidizer air or oxygen in the presence of an organic redox system, e.g. a quinone, especially tetrachlora-o-quinone may be used.  An organic co-solvent, e.g. acetonitrile may be used.  In the examples which contain comparative data using potassium bromoaurate, acetylene, propyne (methylacetylene) and phenyl acetylene are converted, using triphenyl phosphine gold trichloride, to give glyoxal, methyl glyoxal and phenyl glyoxal respectively.  In Example 6 triphenyl gold monochloride crystallized out after the oxidation is suspended in acetonitrile and reconverted to the trichloride with chlorine.

Abstract: 111,416. Smith, M., and Taytor, Garnett, Evans, & Co. April 5, 1917. Bronzing and the like.-In bronzing and like apparatus of the kind in which the powder-laden air is withdrawn from the bronzing chamber by an air-exhauster, means are provided to prevent accumulation of powder on the bottom of the chamber, by conveying settled powder to the air outlet, or to prevent settling of the powder, by means of agitators arranged in the chamber. A sieve extending across the full length and width of the chamber is provided above the conveying or agitating devices. The invention is particularly applicable to the bronzing apparatus described in Specification 19767/05, [Class 101, Printing other than letterpress &c.]. As shown, a number of brushes f carried by a single wide band g or a number of narrow bands, brush the settled powder into the suction opening c of the fan d. Preferably, the arrangement is such that the bristles are bent by contact with the floor a of the chamber b so that, on straightening, they flick the dust into the opening c, but a comb or other means may be provided to flick the dust from the brushes. Instead of the band of brushes f, one or more rotary or other brushes may be employed or a wide band g may act as a false bottom and be driven in the opposite direction to that shown to conduct the dust to the opening c, a brush, scraper, or other means being provided, if necessary, to remove the dust from the band. Rotary agitators comprising rotating shafts fitted with arms or paddles may be provided to prevent the dust from settling on the bottom of the chamber. A sieve e extending across the full length and width of the chamber may be arranged above the powder conveying or agitating means.

Title: Improvements in or relating to pulse code modulation decoders
IPC: H03M1/00
Filed: 1963-02-07
Abstract: 964,762. Pulse code modulation systems. WESTERN ELECTRIC CO. Inc. Feb. 7, 1963 [Feb. 19, 1962], No. 4973/63. Heading H4L. A decoder for pulse code modulation signals is arranged to reconstitute the signal amplitude samples in bipolar form about a potential intermediate between first and second reference potentials so that the direct current component is minimized to facilitate the application of the samples to subsequent circuits. As shown in a system using seven-digit code groups with an eighth digit for supervising purposes, a pulse group after conversion to parallel form is supplied to inputs 11 to 17 to coincide with pulses D1, input 11 receiving the most significant digit and so on. Each binary " 1 " is a negative pulse and each binary " 0 " is a positive potential which also forms the base line of the incoming pulse train. Pulses on lead 11 are supplied to the inhibit terminal of an INHIBIT gate 21 so that positive-going timing pulses D1 are passed via an OR gate 31 to control a switch 41 except when a digit appears at input 11. Positive pulses applied to switch 41 (binary "0" input) cause weighting resistor 51 to be connected to - EREF otherwise resistor 51 is connected to earth. The remaining digits are supplied to respective AND gates 22 to 27 receiving also pulses -D1. If a binary " 1 " is present a signal is passed via the corresponding OR gate 32 to 37 to control a corresponding switch 42 to 47 and connect the weighting resistor 52 &c. to earth. A binary " 0 " input causes the corresponding weighting resistor to remain connected to - EREF. Digit pulse -D6 returns resistor 51 to its " between samples " potential of earth and digit pulse +D6 returns resistors 52 to 57 to their " between samples " potential of - EREF. As shown, the first code group in channel 1 is 1001101, i.e. the amplitude level 77. During digit time D1 resistor 51 is left earthed, those associated with the second third and sixth digit spaces are left connected to EREF, and those associated with the fourth, fifth and seventh digit spaces are connected to earth. The reconstructed amplitude sample appearing at output 61 is shown at F. Channel 2, 3 and 4 samples are reconstructed in a similar way, channel 4 being a special case in which input 1000000 representing level 64, i.e. half the maximum possible value, requires that the connections of all the weighting resistors are left unchanged from their position between samples, this being the baseline for the output pulse train. Specifications 845,344, 940,507 and 949,297 are referred to.
