Abstract: 1,065,681. Suction conduits. W. REINERS. April 8, 1964 [April 13, 1963], No. 14464/64. Heading D1J. A suction conduit 100 for holding thread ends in a textile machine-e.g. a winding machine-has a mouth lying in a smoothsurfaced plate 51 which is movably mounted to bring the mouth into position over the conduit end to open the conduit. When a package is inserted in magazen 20 the plate which is mounted on a shaft pivotally mounted on conduit 100 is pivoted and the thread end inserted in the conduit, a spring then returning the plate to clamp the thread. Stops limit the movement of the plate. When a supply package 5 is exhausted and the empty tube ejected a cam 111 causes shutter lever 205 to pivot and thus allow reserve package 5' to fall onto peg 5a which has been pivoted clockwise to receive it. Arms 11 and 10 convey the new thread, whose end is trapped between plate 51 and conduit 100, to knotting device 9 while arm 6 supplies the thread end from take-up spool 4. After knotting, the thread end leading to conduit 100 is severed, and cam 111 causes, through rod 108, plate 51 to pivot to open the conduit so that the clamped thread end may be released and sucked away. Instead of a round magazine 20, a series magazine, as in Specification 931,675, may be used.

Title: Manufacture of sulphur-containing organic compounds
Filed: 1939-05-15
Abstract: 533,565. Diaminodiphenyl sulphone derivatives. ROSE, F. L., and IMPERIAL CHEMICAL INDUSTRIES Ltd. May 15, 1939, No. 14499. [Class 2 (iii)] 4:4<SP>1</SP>-Diaminodiphenylsulphone derivatives of the formula wherein R stands for an alkylene residue and A represents hydrogen, an acyl group or a residue HOOC.R.CO, are prepared by oxidizing the corresponding sulphide or sulphoxide, e.g. with hydrogen peroxide, chromic acid, or per-acids and their salts. Products in which A represents hydrogen or an acyl group may also be prepared by reacting an acid HOOC.R.COOH or its anhydride with diaminodiphenylsulphone or an amino-acylamino-diphenylsulphone. Finally, products in which A represents hydrogen may be prepared by reducing the nitro group of the corresponding nitro-acylamino-diphenylsulphone, e.g. with iron and hydrochloric acid or zinc dust and acetic acid. The products, in the form of their salts with inorganic and organic bases, are useful therapeutically. According to the examples, (1) 4-amino-4<SP>1</SP>-acetyl or benzoyl-aminodiphenylsulphone (see Specification 517,457) is heated with succinic anhydride to give the 4-succinylamino compounds ; (2) 4-nitro-41- succinylamino - diphenylsulphone, prepared by reacting 4 - nitro - 4<SP>1</SP> - amino - diphenyl - sulphone with succinic anhydride or by oxidizing 4 - nitro - 4<SP>1</SP> - succinylamino - diphenylsulphide with hydrogen peroxide in acetic acid or ammonium persulphate in sulphuric acid, is reduced with iron borings and concentrated hydrochloric acid ; (3) 4:4<SP>1</SP>- diaminodiphenylsulphone is heated with succinic anhydride to give the same 4<SP>1</SP> - succinylamino product as in (2) ; (4) 4:4<SP>1</SP> disuccinylaminodiphenylsulphide is oxidized to the sulphone by means of ammonium persulphate in cold concentrated sulphuric acid ; in the same way 4-amiho-4<SP>1</SP>-succinylamino-diphenylsulphoxide is converted into the corresponding sulphone ; (5) 4-amino-4<SP>1</SP>-maleyl and adipylamino - diphenylsulphones are prepared by heating 4:4<SP>1</SP>-diaminodiphenylsulphone with maleic and adipic anhydrides respectively. The derivatives of diphenyl-sulphide and sulphoxide used as starting materials are prepared by acylating the diamino- or nitroamino-diphenyl-sulphide or sulphoxide, and if necessary reducing the nitro compound and acylating the amino group formed. Thus, 4-amino - 4<SP>1</SP>-succinylamino - diphenylsulphoxide is prepared by heating 4-nitro-4<SP>1</SP>-amino-diphenylsulphoxide with succinic anhydride and reducing with iron and hydrochloric acid ; while 4-nitro-4<SP>1</SP>-succinylamino-diphenylsulphide is obtained by treating the corresponding 41-amino compound with succinic anhydride,. and 4:4<SP>1</SP>-disuccinylamino-diphenylsulphide by heating 4:4<SP>1</SP>-diaminodiphenylsulphide with succinic anhydride.

Filed: 1971-05-13
Abstract: 1310186 Radio receiving circuits; stereophonic radio receivers SONY CORP 13 May 1971 [15 May 1970] 14766/71 Headings H3Q and H4L  The invention comprises a control signal generating circuit in an F.M. receiver having a plurality of I.F. stages, and comprises a bandpass circuit having a narrower frequency band than that of the I.F. stages, means for applying I.F. to the bandpass circuit, means for rectifying an output signal from the bandpass circuit and a detector circuit for rectifying an I.F. signal to produce a control voltage, being characterized by means for applying the output of the rectifying means to the detector circuit to control its operation. Narrow-band filter circuit 5 Fig. 2 is coupled to the last stage of the I.F. amplifier (Fig. 1, not shown) and feeds a rectifier circuit 6 comprising diode D1 and the base-emitter path of transistor Q1, the base of which is biased by means of diode D2. The rectified output is amplified by transistors Q2, Q3 and smoothed by integrating circuit 7, being applied over emitter-follower Q4, Q5 to diodes Da-Dc. Each of the diodes Da-Dc provides bias for a corresponding detector diode D<SP>1</SP>a- Dc, the terminals between corresponding pairs of diodes being coupled to successive I.F. amplifier stages (Fig. 1, not shown). The outputs from detector diodes D<SP>1</SP>a-Dc are smoothed and then combined and fed to a tuning meter M. The arrangement may be simplified to comprise only one pair of diodes Da, D<SP>1</SP>a (Fig. 6, not shown) coupled to a single I.F. stage, and may also be used to provide a muting voltage. In a stereophonic receiver, the outputs from two controlled detectors 8a, 8b, Fig. 7 are combined and fed to a transistor Q7, the collector circuit of which provides a gate bias for field-effect transistor Q8: the source and drain of transistor Q8 are respectively connected to the two stereo channels over capacitors C2, C3. Variable bias resistor R6 is adjusted so that transistor Q7 turns on when the input exceeds a value E1 Accordingly, for this and higher signal levels field-effect transistor Q8 is biased non-conductive. For lower levels, at which noise is appreciable, transistor Q7 is not tuned on and transistor Q8 is conductive, coupling the two stereo channels together for frequencies higher than 7 KHz, and decreasing the noise in the output.

Patent GB-578004-A (GB)
Title: Improvements in and relating to the manufacture of sulphathiazole derivatives
Filed: 1944-08-04
Abstract: 2 - (p - Acylaminobenzenesulphonamido) - thiazoles are obtained by interacting substantially 2 molecular proportions of a 2-aminothiazole, optionally substituted in the nucleus, and 1 molecular proportion of a p-acylaminobenzenesulphonyl halide in an inert solvent.  The excess 2-aminothiazole functions as a condensing agent and is recoverable as the corresponding hydrohalide, or by a sparingly soluble salt of a sulphonic acid. Specified aminothiazoles are 2-aminothiazole, 4-methyl-2-aminothiazole and 2-aminobenzthiazole, and the acyl residue in the aminobenzenesulphonyl halide may be acetyl, propionyl, benzoyl, or the radical of a dibasic acid, e.g. phthalic, terephthalic or succinic acid.  In examples: (1) p-acetylaminobenzenesulphonyl chloride is added to 2-aminothiazole in benzene and the mixture is refluxed prior to removing the solvent, digesting the residue with 5 per cent cold hydrochloric acid and isolating the residue; (2) p-succinimidobenzenesulphonyl chloride is added to 2-aminothiazole in benzene and the solution is refluxed as in (1), prior to digesting the residue with water to yield p-succinimidobenzenesulphonamido-thiazole, hydrolysed by boiling with 0.5N caustic potash and subsequent treatment with dilute hydrochloric acid to isolate N4-succinylsulphathiazole. p-Succinimidobenzenesulphonyl chloride is obtained by the interaction of chlorosulphonic acid and succinanil.

Title: Improvements in safe load indicators for cranes and the like
IPC: B66C23/90
Filed: 1935-05-22
Abstract: 457,124. Safe - load indicators for cranes &c. WALLS, A. G., 10, Airlie Terrace, Dundee. May 22, 1935, No. 14912. [Class 78 (iv)] [See also Group XIX] The safe-load indicator for cranes and the like described in Specification 375,386 is modified by providing safe - load indicating-mechanism with multiplying - gear having such a range of adjustability that a standard article of manufacture can be fitted to various types of cranes requiring great differences in the movement of the safe-load indicating - finger. To indicate the actual load on the hoisting - rope, the latter passes from the drum 8, Fig. 1, round the fixed pulley 9 near the head of the post to a movable pulley 5 displaceable against the action of a spring and thence over the pulley 2 to the jib head and the load hook. The movement of the pulley 5 is transmitted by a rod 4 to a flexible cable 36, Fig. 3, penetrating into the box 3 secured on the post inside the operator's cabin and attached inside the box to the pivoted quadrant 35 that carries the weightindicating pointer 34. This pointer can be adjusted on the quadrant. To indicate the safe load at any particular radius of the jib, a lever 6, Figs. 1 and 2, passing through the rear wall of the box, is maintained parallel to the jib by a telescopic link 7, so that outward movement of the jib within the radius at which the maximum designed load may be lifted, merely moves the rod 7 in the tube 16, but movement beyond this radius brings the member 17 against the cap 18 and imposes a progressive pull on the lever 6. The latter rotates the shaft 12 which occupies the position A ... B in Fig. 3 and carries a bevel wheel 19 rotating a pivoted arm 22 connected by a link 25 to a lever 27 pivoted on the shaft 28 that carries the safe load indicating finger 29. This linkage constitutes a readily-adjustable multiplying-gear between the jib and the finger 29, which provides for a rapid travel of the finger during the safe outreach of the jib for maximum capacity load, and a progressively slower travel as the outreach increases beyond this point. The finger carries differently-coloured sections 30, 31 and coincidence between the pointer 34 and the centre line 33 of the finger 29 may establish an electric circuit to give an audible or visual signal and may cut off the power from the motor. By angular adjustment of the bevel wheel 19 the setting of the finger 29 can be adjusted. Fig. 4 shows a modified multiplying-gear in which the link 25 is connected to an arm 39 which is fixed on a shaft 37 carried by the lever 22 and has a heavy pendulum 38 fixed thereto. The pendulum may be replaced by a pair of links 40, 41 of which 41 is pivoted to a fixed point. Fig. 5 shows a further multiplying-gear in which the angular movement of lever 27 is communicated through toothed gearing 43, 44, 45 to a separate shaft 28 carrying the finger 29.,
