Title: Improvements in sound-deadening compositions
IPC: G10K11/16
Filed: 1938-03-01
Abstract: 513,255. Bituminous compositions. MORTELL CO., J. W. March 1, 1938, Nos. 6449 and 6450. Convention dates, May 14, 1937, and Nov. 8, 1937. Drawings to Specification. [Class 22] [Also in Group III] A resilient metal plate is coated with a sound deadening composition, comprising a mixture of an emulsified asphalt and a dense filler having a specific gravity of at least 1.2 e.g. sand, amounting to at least 40 per cent. of the weight of the mixture before drying. The metal plate may be used in vehicle construction. The asphalt emulsion may be made for instance by emulsifying heated Mexican asphalt using clay as an emulsifying agent or may be a homogenized emulsion made by emulsifying and passing the resulting emulsion through a second emulsifier to homogenize it, the agitators in both emulsifiers rotating at about 1,750 r.p.m. Compositions exemplified are (1) Mexican asphalt emulsion 55, silica sand 45 ; (2) homogenized asphalt emulsion 33, sand 67. The composition may be applied to the plates by spraying, painting or trowelling, as. a layer from 1/16 to 3/16 ins. thick, or be used as an adhesive for cementing insulating slabs thereto. The layer may be air dried or baked.

Title: Filter
IPC: B01D25/12
Filed: 1950-03-15
Abstract: 693,568. Filters; filtering media. FILTROX-WERK AKT.-GES. March 15, 1950 [March 15, 1949], No. 6535/50. Class 46 [Also in Group XXVIII] The elements between adjoining frames of a pressure filter each consist of a mechanically resistant porous carrier plate together with a porous filtering layer readily replaceable after saturation supported in front of it; the carrier plate has a useful life appreciably greater (e.g., sixty times greater) than that of the replaceable layer. In a filter press comprising inlet and outlet frames 1 arranged alternately, and having carrier plates 3 between them, the plates 3 may consist of fibres such as wool, cotton, rayon, nylon or glass or mixtures of these, and may be formed before or after treatment with binding agents by weaving, plaiting, felting, pressing or similar processes. The material is rigidified by a binding agent which does not impair the porosity of the basic material and is insoluble in the liquids to be filtered, examples of such binding agents being synthetic plastic materials, cellulose acetate, artificial resins and water glass. The plates resist high liquid pressures even in wet condition and do not shrink. The plates 3 are coated with a slurry 4 of a kieselguhr, sand, pulverized charcoal or other suitable filter aid by passing the slurry in the direction indicated. Upon saturation of the layers 4 with filtration residues, the plates 3 are removed from the press and the layer 4 flushed or scraped off. In a modification each carrier plate is covered with a co-extensive coherent plate in place of the slurry layer and made from materials appropriate to the slurry to be-filtered, such as from textiles, paper and the like. In each case the porosity of the layer supported by the carrier plate is preferably smaller than that of the carrier plate. The carrier plate itself however may possess sufficiently minute pores to be efficient alone; its resistance is preferably such that the liquid must be supplied under pressure, so that the slurry becomes uniformly distributed over its surface. The binding agent of the carrier plate may prevent the growth of fungi and bacteria.

Title: Improvements in or relating to non-contact target apparatus
Inventor: WALSH JOHN
IPC: F41G3/26
Filed: 1955-03-07
Abstract: 818,449. Photo-electric detector systems. RANK CINTEL Ltd., and MINISTER OF SUPPLY. March 7, 1956 [March 7, 1955], No. 6606/55. Class 40 (3). [Also in Group XXXVIII] Photo-electric target apparatus responsive to the near passage of a projectile transmits an R.F. carrier modulated by pulses having a frequency indicative of the sector around the target and duration indicative of the distance of the projectile from the target. In the receiving apparatus the demodulated signal is applied to frequency-responsive filters to determine the sector, and the duration of the pulse is converted to an amplitude signal to indicate the distance. The sector and distance signals may operate indicator lamps or a C.R.T. display. Transmitter, Fig. 1.-A number of photocells each responsive to the passage of a projectile through a sector of an annular zone around the target (as described in Specification 817,446) provide signals to an amplifier 4 (such as described in Specification 817,467) to generate pulses having an amplitude depending on the distance from the target. These pulses pass through a circuit 5 giving an output having a steep rise and exponential decay (so that its duration above a certain value is proportional to the amplitude of the input), to trigger a flipflop circuit 6 operating a " gate " 7 between an oscillator 8 (characteristic of the sector) and a mixer 9 connected to the other sector oscillators. The output of the mixer modulates a transmitted R.F. carrier. Receiver, Fig. 2.-The received signals are demodulated at 17 and fed to a series of filters 18 each passing a particular " sector " frequency, and the output of each filter is demodulated at 19 to provide constant amplitude pulses of variable duration (corresponding to the transmitted signals) which are fed to a common integrator circuit 20 providing output pulses having an amplitude dependent on the duration of the input pulses. (a) Display lamp indicator, Fig. 2.-The output of the integrator is applied to circuits 21 ... 25 selectively responsive to the amplitude of the pulses, to energize annular bus-bars 26 ... 30, and the demodulated output of each filter from circuit 19 is applied also to a trigger circuit such as 37 to energize the appropriate radial bus-bar such as 36 to complete a circuit for the appropriate indicator lamp such as 31 ... 35. (b) C..R.T. Display, Fig. 3 (not shown).- Alternatively the output of the integrator 20 may be connected through gate, circuits controlled by the " sector " filters, to deflection generators (such as those described in Specification 761,461, [Group XL (c)], to energize the radial deflection coils of a C.R.T.

Title: Manufacture of new mordant dyestuffs
IPC: C09B43/06
Filed: 1930-02-28
Abstract: Azo dyes and soluble metal compounds thereof.-Dyes capable of dyeing mordanted wool and silk and of forming soluble chromium or copper compounds are obtained by oxidation of aminoazo dyes of the type R1-N=N-Rn-NH2, or of aminopolyazo dyes of the type R1-N=N-R2-N=N-R3 . . . N=N-Rn,NH2 in which R2 is a benzene nucleus containing an o-oxycarboxy grouping with the OH group in p-position to the azo group, R2, R3 &c. are benzene nuclei connected with each other by azo groups and may be substituted, e.g. by sulphonic or carboxy groups, and Rn is a benzene, nucleus which may carry substituents, e.g. sulphonic or carboxy groups in addition to the amino group which is in p-position to the azo linkage.  The oxidation is preferably effected in an alkaline medium by means of chloride of lime, but other oxidizing agents such as permanganates may be used.  The following examples are specified: (1) The aminoazo dyestuff obtainable by coupling diazotized p-nitraniline or diazotized p-aminoacetanilide with salicylic acid and reducing the nitro group of hydrolysing the acetylamino group is oxidized with chloride of lime in alkaline solution, and the product is sulphonated to obtain a dyestuff giving fast brown-yellow dyeings on chromemordanted fibre. (2) The aminoazo dyestuff obtainable by coupling diazotized p-nitraniline-o-sulphonic acid or diazotized p-aminoacetanilidesulphonic acid with salicylic acid and reducing the nitro group of hydrolysing the acetylamino group is similarly oxidized; the product dyes chromemordanted fibre fast brown tints; similar products are obtained by oxidation of suitable isomerides and homologues of the 4-amino-2-sulphobenzene-azo-salicylic acid, such as 4-amino-3-sulphobenzene-azo-salicylic acid, 4-amino-2-sulphobenzene - azo - o - cresotinic acid, and 4 - amino-2-sulphobenzene - azo - m - cresotinic acid.  (3) The aminodisazo dyestuff obtainable by coupling diazotized p-nitraniline-o-sulphonic acid with aniline -N-methyl-w-sulphonic acid, removing the -CH2,SO3H, diazotizing the amino group, coupling with salicylic acid, and reducing the nitro group is oxidized by means of chloride of lime; the product gives deep brown dyeings on chromed fibre; a similar product is obtained if the aniline-N-methyl-w-sulphonic acid is replaced by the N-methyl-w-sulphonic acid of metanilic acid.  Specifications 19061/91 and 16708/93, [both in Class 2, Acids and salts, Organic &c.], are referred to.  The N-methyl-w-sulphonic acid of metanilic acid is obtained by a process analogous to that of Specification 238,717, [Class 2 (iii), Dyes &c.], by interaction of equimolecular proportions of sodium bisulphite, formaldehyde, and sodium metanilate.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the production of the dyestuffs in which the nuclei R1, R2, R3, Rn are not necessarily of the benzene series, and R1 carries any desired mordanting groups, and includes the use of 4-amino-2-sulphobenzene-azo-p-cresotinic acid as parent dyestuff. This subject-matter does not appear in the Specification as accepted.
