Title: Apparatus and method for automatically and continuously transferring slivers between textile drawing frames
IPC: B65H67/04
Filed: 1961-08-17
Abstract: 942,278. Drawing textile slivers. TOYO BOSEKI KABUSHIKI KAISHA. Aug. 17, 1961 [Aug. 18, 1960], No. 29715/61. Headings D1F and D1N. Sliver from a drawing frame is supplied to a second drawing frame as a plurality of sliver ends by coiling the sliver into a succession of containers and intermittently moving the containers between the first and second drawing frames, severing the sliver between two filled containers and feeding the sliver from the first of the two containers into the second drawing frame. The containers are preferably mounted on a circular turntable but may also be arranged in a triangular or polygonal pattern, or an arrangement may be adopted in which containers are forced into an annular compartment from a position external to the annulus. Where a circular turntable is used, the number of containers is equivalent to the number of slivers supplied to the second drawing frame with the addition of at least one empty container, one filled container and a container located beneath the coiler head of the first drawing frame. The sliver will extend continuously from the container 12 beneath the coiler head 11 to the container 12a previously filled. As one container, say 12g, is emptied the turntable 13 is indexed round to the extent of one container position and, in consequence, the container 12 from beneath the coiler head moves to the reserve position hitherto occupied by container 12a and now in position to supply sliver which is fed to the drawing rollers B<1> in two steps. In the first step, arm 42 swings upwardly to raise the bight of sliver extending between containers 12, 12a and hold the sliver between a hook member at the end of the arm 42 and a fixed flexible member 47. In the second step, an arm 52, Fig. 8, is moved laterally until rollers 55, 59 lie on either side of the sliver extending from the container 12a, an electromagnet 60 is energized to bring the rollers 55, 59 into gripping relationship with the sliver, and the rollers are then swung towards the drawing rollers B<1> until the roller 55 contacts a driven roller 65 from which drive is transmitted to rollers 55, 59 so that the sliver which is severed during the swing of the rollers is fed into the drawing rollers B<1>. Slivers are guided from the containers to the drawing rollers by a curved member 33, Fig. 2, and a guide 30 in the form of a screw that may be continuously rotated, or intermittently turned in synchronism with the indexing of the turntable. Each container 12 is provided with a longitudinal groove 20 that may be set at an angle of about 18 degrees to the axis of the container and a recess 21, the groove and recess serving to guide the sliver extending between adjacent containers.

Abstract: 665,967. Magnetic recording systems. BRITISH ACOUSTIC FILMS, Ltd. Nov. 21, 1949. No. 29762/49. Class 40 (ii). [Also in Groups XL (c)] The necessary operating power supply for the input stage of a thermionic valve amplifier. particularly of the universal type, is provided by a supersonic oscillator which also supplies either or both a high frequency bias current, and a wiping current to magnetic heads in a magnetic sound recording system. As shown, the anode supplies for the output stage V2 of an amplifier, and a supersonic oscillator V3 are provided from the A.C. or D.C. mains supply through a halfwave rectifier V4. The anode supply for the input stage VI is taken from the secondary S2 of the oscillator output transformer T4 through a rectifier V5 and filter C6, C7, R4. The heater supply for input valve V1 is taken from a separate winding H1-H1 on the oscillator transformer T4, which may also provide the high frequency supply for the magnetic heads (not shown). The supply to the magnetic heads may be taken from a separate winding L1-L1. The primary winding of transformer T4 and condenser C8 form the tuned anode circuit of the supersonic oscillator V4. The input stage V1 is coupled to the output stage through a transformer T2 which is preferably constructed so as to have a low impedance and capacity. The output stage may be a push-pull stage fed by a push-pull transformer. The arrangement enables one side of the input to be earthed without interfering with the mains supply.

Title: An improved means of angularly adjusting variable-coupling coil-holders and like instruments used in wireless sets
IPC: H01F27/00
Filed: 1923-11-27
Abstract: 226,019. :Philpott, F. H. Nov. 27, 1923. No Patent granted (Sealing fee not paid). Wireless tuning-apparatus, adjustment devices jor.-A movable coil holder A for angularly adjustable variable-coupling coils &c. is a frictional fit on a spindle B which is itself a frictional fit in bearings C. Arms E fixed on one end of the spindle provide at their upper ends bearings for an operating handle F, which carries a collar G and a slotted arm H engaging a pin A<1> on the holder A. The collar G carries two arms G<1> adapted to engage a stop pin J. Angular movement of the handle F moves the holder A, by means of the arm H and pin A<1>, about the spindle B until one arm G<1> engages the pin J. Further movement of the handle F then rotates the spindle B, which carries with it the holder A, effecting a rapid adjustment. Reverse movement of the handle F now moves the holder alone by means of the arm H and pin A<1>, giving a fine adjustment within the limits of the arms G<1> and pin J. In a modification, the spindle is carried at both ends on crank arms having journals rotatable in the bearings C, and the handle F is carried through one of these journals. In another modification, the handle F is fixed to a block pivoted to the holder A and having at its lower end a slot engaged by the pear-headed end of an arm on the spindle B. The slot is so shaped as to allow angular movement of limited amplitude of the block relatively to the pear-headed arm.

[Class 2 (iii)] Indigoid vat dyes are made by oxidizing a naphthioihdoxyl of the general formula where X = chlorine or bromine and Y = an alkoxy group, or by condensing such naphthioindoxyl or a reactive 2-derivative thereof with a component suitable for the manufacture of indigoid dyestuffs, e.g. another naphthioindoxyl or a reactive 2-derivative thereof; if desired, the product may be halogenated. Naphththioindoxyls specified are 5-chloro (or bromo)-6- methoxy-2:1-naphthioindoxyl, or its α-(p-dimethylamino)-anil, and other components specified are isatins and indoxyls of the benzene or naphthalene series, thionaphthenequinones, oxythionaphthenes, acenaphthenequinones. The condensation may take place in a solvent such as alcohol, benzene, chlorbenzene, or tetrachlorethane, and the halogenation in sulphuric acid solution or in presence of nitrobenzene or chlorbenzene. The products dye or print cotton, wool, silk, and artificial silk and may be converted to leuco-ester salts. In examples, 5-chlor-6-methoxy-2:1-naphthioindoxyl is (1) oxidized with sulphur in boiling caustic soda lye (olive tints on cotton), or condensed with (2) the 2-(p-dimethylamino)-anil of 2.1-naphthioindoxyl (olive-brown tints on cotton) or 5-chlor-7-methyl-3-oxythionaphthene (bordeaux tints), (3) the 2-(p-dimethylamino)-anil of 3- oxythionaphthene (bordeaux tints), (4) 5- bromisatinchloride (violet-brown), (5) 4-methyl- 5-chlor-7-methoxyization (blue tints), (6) 5- bromisatin or 5.7-dibromisatin (brown tints). In further examples, (7) the product obtained as under (6) above using 5-bromisatin is brominated in sulphuric acid and (8) the product obtained as under (2) above from the 2-(p-dimethylamino) anil of 2.1-naphthioindoxyl is vatted and used to dye cotton. 1-Chloro - 2-methoxynaphthalene 6-sulphonic acid is made by diazotising 1-amino-2-methoxynaphthalene-6-sulphonic acid and reacting the diazo compound with cuprous chloride. 1-Chloro-2-methoxynaphthalene-6-thioglycollic acid is made from 1-chloro-2-methoxynaphthalene-6-sulphonic acid by conversion of the latter to its sulphochloride, which is reduced to 1 - chloro - 2-methoxy - 6 - mercaptonaphthalene, which is condensed with chloracetic acid. 5-Chloro-6-methoxy-2:1-naphthioindoxyl is made by reaction of 1-chlor-2-methoxynaphthalene-6-thioglycollic acid with phosphorus trichloride and aluminium chloride. The α-anils of such naphthoindoxyl are made by the action of nitroso compounds.
