Title: Manufacture of halogenated compounds
IPC: C09B47/10
Filed: 1935-08-14
Abstract: Green pigments are obtained by chlorinating or brominating a phthalocyanine to such a degree that the sum of the halogen atoms present in the molecule is at least 8.  Chlorine, bromine, thionyl chloride or sulphuryl chloride may be used for halogenation and a halogen carrier such as aluminium chloride or bromide, antimony tri- or pentachloride, ferric chloride, zinc chloride, iodine, sulphur, sulphur chloride, phosphorus pentachloride, may be present; reaction may take place in a solvent or diluent, and in some cases unstable combinations of phthalocyanine and halogen first formed are converted to stable products by a heat treatment or by treatment with basic substances.  In examples: (a) metal-free phthalocyanine is treated with bromine in an autoclave at 300 DEG  C. for 2 \ba1/2\be hours, and the product then heated in vacuo at 250 DEG  C.; or with chlorine at 250 DEG  C. for 6 hours; or with sulphuryl chloride in an autoclave for 4 \ba1/2\be hours at 230 DEG  C.; or with sulphuryl chloride and anhydrous aluminium chloride in a closed vessel at 200--210 DEG  C. for \ba1/2\be hour followed by treatment with aqueous caustic alkali (the product contains aluminium); or with thionyl chloride and sulphuryl chloride at the boiling point for 48 hours with or without the additional introduction of chlorine gas; (b) copper phthalocyanine is heated with bromine in a sealed vessel at 210 DEG  C. for 2 \ba1/2\be hours, the product then heated at 260 DEG  C., and finally with more bromine at 290 DEG  C. for 5 hours; (c) copper octachlorphthalocyanine (prepared by reacting together 3.6-dichlorphthalic anhydride, cupric chloride and urea) is heated with bromine in a closed vessel at 270 DEG  C. for 15 hours; (d) nickel or zinc phthalocyanine is heated with bromine in a sealed vessel at 250 DEG  C. for 15 hours, and the products heated at 260 DEG  C. until no bromine or hydrogen bromide is evolved.  It appears possible by direct halogenation to introduce not more than 12 halogen atoms.  Specifications 322,169, [Class 2 (iii)], 389,842, 390,149, and 410,814 are referred to.

Abstract: 444,457. Ironing-presses. HANNEY, A. F., 2423, Park Avenue, Norwood, Ohio, U.S.A. Aug. 16, 1935, No. 23071. [Class 138 (ii)] The pressure fluid exhausted from the pressoperating cylinder 18 during the press-opening movement is used to operate an ejector to create a suction through one of the press members. As shown the buck 14 is provided with longitudinal ribs 44 supporting the padding 45 and having apertures 48 at their bases communicating with a pipe 49 having an extension 50. The buck is slidably carried by a carriage 12 and when it is moved to the loading and unloading position out of registration with the head 11 the end of the pipe 50 is closed by a spring-biassed flap valve 52. Initial upward movement of the piston within the cylinder 18 draws the carriage backward so that the buck registers with the head; further movement of the piston forces the buck vertically into pressing engagement with the head. As the carriage approaches the position wherein the buck and head register, the valve 52 is automatically opened and when the buck and head register the end of the pipe 50 is over a steam-jacketed sump 55 and directly beneath the muffler 43 in the exhaust pipe 37 of the cylinder. When the manual 42 is actuated to close the pressure fluid inlet valve 38 and open the exhaust valve 39 the exhaust from the cylinder, after passing through the muffler, passes through the end of the pipe 50 and creates the suction. Water of condensation from the buck is evaporated in the sump 55 and escapes to atmosphere through port 60.

Title: Improvements in automatic ribbon reverse mechanism for typewriting machines
IPC: B41J33/514
Filed: 1920-08-05
Abstract: 165,351. Marks, E. C. R., (Corona Typewriter Co., Inc.). Aug. 5, 1920. Ink-ribbon mechanism. - Automatic reversal mechanism comprises spool gears shiftable relatively to the associated spools and driving- gears, and means normally held retracted by the turns or ribbon on the spools and operable when the ribbon is exhausted from either spool for shifting the gears simultaneously in opposite directions to reverse the drive. The spools consist of a sleeve 2, Fig. 5<a>. fitting on a post 1 on a support 17, a bottom disc 6 attached to the sleeve 2, and an upper disc 13 having a sleeve 7 fitting over the sleeve 2 and keyed to it by a spring lug 7<a> snapping into a slot. The portion of the sleeve 2 below the disc 6 is squared to carry a sliding gear 3 engageable with a worm on the driving-shaft, the gears 3 of the two spools being interconnected by means of bell-cranks 4 and a link 11, Fig. 1, for simultaneous movement in opposite directions. The disc 6 is formed with a pivot lug 6a and a slot 6<b> to support a spring-projected yoke-shaped lever 5 having an arm 5<b> extending upwards through the slot 6<b> for retention against the core of the spool by the turns of ribbon. When released, the lever depresses the associated gear 3, and an arm 5<c> of the lever is brought to bear on an annular camtrack 9<c> for restoring the lever into position for re-engagement by the ribbon as the spool turns. The cam-track is formed on a stationary spool cup 9 concentric with the sleeve 2, and is inclined for about half its length, the remainder being level with the top of the incline. A gap is made at the lowest point of the incline to permit the outward movement of the arm 5<b> when brought into register in the rotation of the spool. As the arm 5<b> might not be securely held by only one or two turns of ribbon, a switch 8 is provided to constitute with the level portion of the track a continuous annular track, bridging over the incline; the end of the switch adjacent to the gap in the cam-track is bevelled to raise the arm 5<b> should it have partly dropped in crossing the gap. For manual reversal, a shift-lever 10, Fig 1, is provided for the link 11, movable between stop arms 12<a> and associated with a spring which assists to complete the movement of the link after the lever has reached the middle position. A ribbon guide 9<f> is formed on each spool cup diametrically opposite the gap in the cam track, and the vertical flange 9<a> of the cup is gapped adjacent to the guide to form a passage for the ribbon.

Abstract: 1,016,930. Television local viewing systems; valve oscillating circuits. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. June 1, 1964 [June 11, 1963; Jan. 3, 1964], Nos. 23211/63 and 434/64. Headings H3F and H4F. [Also in Division H1]  Television local viewing systems.-In a highspeed camera, Fig. 3, an image of the phenomenon to be observed is formed on the photocathode 1 of an electron discharge tube and releases an electron image which is focused on to an output screen 4. The electron image is swept across an apertured electrode 5 by a first pair of deflector plates 6 so as to produce a shutter action, whilst the electron image passing through the aperture is swept in the opposite direction by a second pair of plates 7 so as to immobilize the image formed on screen 4. In accordance with the invention the two deflections are produced by oscillations A and B, Fig. 2, of the .same frequency and waveform but differing in phase by 180 degrees plus a small angle (21 degrees in the example described) Exposure is obtained when the image passes through the aperture in plate 5, i.e. when the potential of plates 6 is within the range defined by the horizontal dotted lines on waveform A. The exposure interval is denoted by T. Alternate exposures are immobilized by the portions a<SP>1</SP>, b<SP>1</SP> and c<SP>1</SP>, d<SP>1</SP> of the waveform B which are symmetrically placed about the zero axis due to the phased differences of the waveforms. As a consequence alternate images appear on screen 4 in two positions one above the other. By applying a horizontal deflection, waveform C, to further plates 9 a sequence of images (e.g. 8 or 16) may be formed as illustrated in Fig. 4. The oscillations A and B are produced by a special oscillator (see below), whilst waveform C is produced by an arrangement involving a pulse generator 29 which controls a modulator 16 to pass a number of cycles, i.e. 8 or 16, from oscillator 14 to an integrator stage 17 which generates the waveform in response to the positive peak of each cycle. The cycle, ,of operations is completed by triggering a spark switch 18 which short-circuits the discharge tube EHT supply. The image formed on screen 4 may produce a visible image which is photographed (as illustrated) or may produce a charge pattern which is scanned to produce an electrical signal. Reference is made to the use of triangular deflection waveforms. Valve oscillating circuits.-Phase-displaced waveforms A and B, Fig. 2, are generated by a reaction type oscillator circuit, Fig. 5, having two resonant circuits 19A, 20A and 19B, 20B which are tuned to slightly different frequencies. The reaction coupling is applied by means of inductor 24 to circuit 19a, 20a, and the two circuits are coupled to give near-critical coupling either by wire 27, which is connected to tapping points symmetrically located with respect to the inductor centre-taps, or by a coupling loop circuit 31.
