Abstract: 311,283. I. G. Farbenindustrie Akt.- Ges. May 8, 1928, [Convention date]. Anthraquinone acridones.- Dianthraquinonylamines of the anthraquinoneacridone series are obtained by causing an aminoanthraquinone or a derivative or substitution product thereof to act on a polyhalogen anthraquinone-N-1 : 2-acridone, containing, in addition to halogen in the phenyl residue a halogen atom in the 4-position of the anthraquinone nucleus, in a high-boiling solvent in the presence of an acid-fixing agent and, as catalyst, copper or a salt thereof. The products are themselves vat dyes, and can be used as intermediates for the production or other vat dyes. In examples, trichloranthraquinacridone is heated in the presence of naphthalene, sodium acetate and cupric chloride with 1-benzoylamino- 4- or 5- aminoanthraquinone, and with 1-aminoanthraquinone; the products dye cotton from an alkaline hydrosulphite vat in grey shades. The product from 1-benzoylamino-5-aminoanthraquinone is identical with the condensation product from Bz-dichlor-4-aminoanthraquinoneacridone (made in accordance with Specification 17764/14, by the use of 3 : 5-dichlor-2-anthranilic acid) and 1-benzoylamino-5-chloranthraquinone Specification 305,082 also is referred to. The Specification as open to inspection under Sect. 91 (3) (a) is not limited to the use of copper or salts thereof as catalysts, and includes an additional example in which a. product dyeing cotton in corinth shades is obtained from trichloranthraquinoneacridone and 1-amino-4-methoxyanthroquinone. It also states that vat dyes of different shade and apparently of carbazole structure may be obtained by treating the products with condensing agents. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to pattern mechanism for selecting weft threads in loomsfor weaving
IPC: D03D45/20
Filed: 1931-05-14
Abstract: 378,112. Selecting wefts in shuttleless looms. GLASS, J. P., Meadowcroft, Balcombe Road, Horley, Surrey. May 14, 1931, No. 14340. [Class 142 (ii).] In pattern mechanism for controlling the selection of weft threads in the manufacture of fabrics with different kinds of wefts, an adjustable pin on a bell-crank lever engages an arm on an oscillatable shaft provided with forked levers for engaging collars on the needles, the rocking of the bell-crank lever serving to withdraw the needles from the pattern band and operate a pawl to rotate the pattern drum. An endless band C, having a longitudinal row of perforations D for each kind of weft, is passed over a series of selector needles H, each of which, on passing through a hole D under the influence of a spring h<2>, permits a contact h<4> to engage a contact h<5>, thereby completing an electric circuit and energizing a magnet J which in turn causes the desired colour of weft to be presented to the weft carrier. The pattern band is advanced by pinions e7, e<8>, on a shaft e<6> which is intermittently rotated by a spring-loaded pawl e<4> on a bell-crank lever e<2>, the latter being oscillated by link connection from an eccentric e<1> on a rotary shaft E. A stud e<12>, adjustably mounted on the bell-crank lever, engages a lever g<1> after each selection and rocks a shaft G, thereby tilting a series of forked levers g<3> which engage collars h<1> and withdraw the needles from the pattern band. The selecting apparatus may be positioned remote from a loom or from a number of looms simultaneously weaving the same pattern. Specification 253,630, [Class 142 (ii), Looms, Kind, &c.], is referred to.

Abstract: 1,184,344. Trimming. CREATORS Ltd. 30 March, 1967 [31 March, 1966], No. 14397/66. Heading B6G. A trim for car bodies, furniture or other articles comprises an extruded strip of plastics material of which the front surface displays a decorative finish and the rear surface is provided with an open groove or channel containing an uncured bonding material. An electric conductor is embedded in the bonding material in the groove so that by passing an electric current through the conductor it can be heated to cure the bonding material and bond it to the surface of the car body or other article. The bonding material may be a neoprene-based composition. In Fig. 2 the strip 2 is extruded of crystal clear polyvinyl chloride 3 with a core 4 of polyvinyl chloride having a thin foil 5 of transparent plastics material which is metallized on its surface embedded therein. The metallization may be a vapour deposited coating of aluminium. The rear surface 6 of the extrusion is formed with an undercut open channel 7 which is filled with an uncured neoprene-based heat-curable bonding composition 8 having an insulated resistance wire 9 embedded therein. The ends of the trim are provided with a shaping finish such as shown at 10 by heating in a high frequency jig which is contoured to produce the desired form. This operation closes the ends of the groove 7. The ends of the wire 9 may project from the rear surface of the trim and pass through holes in the body to which the trim is to be secured, or alternatively may be brought out between the rear surface of the extrusion and the body surface, the ends being cut off short and tucked beneath the side zone of the rear surface of the extrusion after bonding to the body.

Title: Improvements in or relating to the deposition of thin metallic layers, and to controlling such deposition
IPC: G01B7/02
Filed: 1948-05-28
Abstract: 669,735. Determining physical qualities and dimensions of materials. FALCK, N. F., and LUMALAMPAN AKTIEBOLAG. May 28, 1948, No. 14448/48. Class 37. [Also in Group XI] Apparatus for applying a thin metallic layer upon an object such as the interior surface of a lamp bulb or reflector, is controlled by the change in the Q-value of a coil which is located closely adjacent to the object and connected in an oscillatory valve circuit which operates to switch off the means for applying the metallic layer when a predetermined thickness or extent of covering corresponding to a particular Q-value of the coil is attained. In an example aluminium is volatilized by the heat from a temporary filament within an electric lamp bulb around which a coil 13 is positioned on a cylindrical former. The coil 13 is connected in the grid circuit of a valve 32 provided with tunable grid and anode circuits, and the grid circuit includes the coil of a relay 34 which has its contacts connected in a low voltage circuit arranged in turn to control the higher voltage circuit of the heating filament. With the valve circuit tuned into oscillation condenser 29 is adjusted in accordance with the thickness of the metal layer required. Relay 34 is thus closed, and closes relay 37 to energize a transformer supplying the filament heating current. As the aluminium becomes deposited on the inner wall of the bulb the Q- value of coil 13 decreases until it becomes such that the grid current is insufficient to hold the relay 34 closed, whereupon the circuit of the heating filament is broken. Alternatively the control may be made dependent on the change of frequency of the oscillatory current relative to a master oscillator. The apparatus may comprise a rotary turret machine with a series of holders for inverted lamp bulbs which are disposed around its periphery and indexed intermittently towards a work station where the coil 13 is lowered automatically into close proximity with the end of the bulb, while current is fed to the heating filament through slip-ring contacts (see Group XI).

Title: Improvements in methods of adjusting the compositions of mineral mixtures
IPC: B07B9/02
Filed: 1938-05-14
Abstract: 514,754. Selective grinding of mineral mixtures. JORGENSEN, M. VOGEL-. May 14, 1938, No. 14485. [Class 59] A method of adjusting the composition of a mineral mixture consists in grinding together grains of a certain size of one component and similarly sized grains of another component, differing in hardness from the first component by means of grinding bodies of such a size that the softer grains are reduced whilst the harder grains are left substantially unaffected whereby the ratio of the average grain size of the hard and soft components is changed. Separation of part or all of the mixture is then effected in accordance with grain size and thereafter a composition of any desired proportions may be made up. As applied to the preparation of starting material for the manufacture of cement the rock contained 63 per cent. lime and the quartz grains embedded therein varied in size from .05 to .6 mm. The rock was then ground in a jaw crusher 1 to about 10 mm. and then further reduced to .06 mm. in a ball mill 2 working in a closed circuit with a separator 3. Balls of 30-40 mm..size were used in this mill and the quartz grains were ground only to a slight extent. Of the quartz in the original material 1¢ per cent. consisted of grains below .05 mm., whilst in the product resulting from. the closed circuit grinding 6 per cent. of the quartz was below .05 mm. As the fraction of the material below .05 mm. contained so little quartz and was rich enough in lime for use this fraction was removed in a second separator 4, and the balance ranging from .05 to .6 mm., was submitted to selective grinding in a mill 5 containing steel balls of 5 mm. The size of the balls was previously determined by experiment and were found to crush the lime and not the quartz between a grain size of .05-.6 mm. The material supplied to the mill contained 40 per cent. quartz and the output was divided in a further separator 6 into fractions above and below .05 mm. The fine fraction contained 75 per cent. calcium carbonate and 25 per cent.. quartz, and the coarse fraction 30 per cent. calcium carbonate and 70 per cent. quartz. The mixture of the two fine fractions (separated out respectively before and after the selective grinding) contained 80 per cent. calcium carbonate and 20 per cent. quartz. The calcium carbonate content is too high for the mixture to be used straight away for the manufacture of cement, but the adjustment of a mixture containing too much calcium carbonate is readily effected.

Abstract: 846,132. Recording sound. ELECTRIC & MUSICAL INDUSTRIES Ltd. May 2, 1958 [May 9, 1957], No. 14734/57. Class 40 (2). In an apparatus for producing a laterally modulated grooved record having variable depth of cut, the spacing of adjacent grooves is made adjustable in dependence on both amplitude of modulation and depth of cut. Fig. 3 illustrates diagrammatically the method of the invention as applied to single channel (monaural) recording. Sound signals from a magnetic master record 7 are picked up by a head 8 and fed to a cutter head 13. Advance signals from a head 18 are amplified and rectified to produce a control voltage to vary the speed of a motor 24 driving a lead-screw 25 the speed of which is thus varied in accordance with the amplitude of the signal. A branch channel 28, 29, 30 produces a further control voltage to control the depth of cut in accordance with the signal amplitude, and via a path 36 also produces an additional control voltage to the motor 24. A further embodiment describes, with reference to Fig. 5 (not shown), a system for use with two-channel (binaural) recording, in which the varying depth of cut represent the modulation of one of the channels.
