Title: Process for the manufacture of diazotising azodyestuffs
IPC: C09B39/00
Filed: 1935-05-14
Abstract: Azo dyes; azo dyes, forming upon the material.--Azo dyestuffs are manufactured by monodiazotizing 3 : 3<1>-diaminodiphenylurea or a homologue thereof and coupling on the hydroxyl side with 1 : 5 : 7- or 2 : 8 : 6-aminonaphtholsulphonic acid or a peri-aminonaphtholsulphonic acid, which may be already coupled on the amino side.  Coupling is usually effected in alkaline medium, but when using a peri-aminonaphtholsulphonic acid coupling may also be effected in an acetic acid medium, whereby coupling may take place on the amino as well as on the hydroxyl side.  The dyestuffs are further diazotizable or tetrazotizable in substance, or may be diazotized or tetrazotized on the fibre and developed, e.g. with b -naphthol or m-toluylenediamine.  In examples, 3 : 3<1>-diaminodiphenylurea is monodiazotized and coupled in alkaline medium with: (1) 2 : 8 : 6-acid; the product dyes cotton corinth shades which may be diazotized on the fibre and developed with m-toluylenediamine to a violet brown; (2) 1 : 8 : 3 : 6-acid; the product dyes cotton corinth shades which may be diazotized on the fibre and developed with m-toluylenediamine to a deep brown; the coupling component may be replaced by 1 : 5 : 7-acid, the developed dyeing being brown; (3) the dyestuff p-nitraniline --> (acid) 1 : 8 : 3 : 6-acid, reduced with sodium sulphide; the product dyes cotton green shades which may be diazotized on the fibre and developed with acetoacetic ester to a full green.  A sample has been furnished under Sect. 2 (5) of the dyestuff obtained by monodiazotizing 3 : 3<1>-diaminodiphenylurea and coupling in an acetic acid medium with 1 : 8 : 3 : 6-acid.  A dye-card shows the shades obtained with the product before and after diazotizing on the fibre and developing with b -naphthol.

Title: Improvements in or relating to vapour or gaseous electric discharge devices
IPC: H01J13/48
Filed: 1934-05-11
Abstract: 420,872. Converting. WESTINGHOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A.-(Assignees of Ludwig, L. R. ; 738, Princeton Boulevard, Wilkinsburg, Pennsylvania, U.S.A.) May 11, 1934, No. 14247. Convention date, May 27, 1933. [Class 38 (ii)] [See also Group XL] The exciting anode 4 of a mercury vapour discharge tube is surrounded by a shield 7 which extends close to the cathode 3 ; the shield is insulated from the anode 4 by spacing or a quartz inset, and its potential is controlled by a switch 11. The main discharge to the anode 2 cannot be instigated even if this anode is at a positive potential, until the shield is made positive. As shown in Fig. 1 the main discharge is interrupted by means of a circuit including a condenser 13, battery 16 and switch 15 ; a spark-gap 14 is placed across the condenser 13. For use in converting continuous to alternating current, two discharge tubes 1, 1<1>, Fig. 2. are connected to the ends of an inductance 24 in the alternating circuit, the mid-point 23 being connected to the generator 21. A condenser 27 connected between resistances 26, 26<1> in circuits to the shields 7 controls the potentials of these shields and the working of the tubes. Instead of mercury cathode and vapour filling, thermionic cathodes and gaseous filling may be used. The shield need not completely surround the anode 4. A number of anodes in one tube can be controlled by a single shield 7. In an inverter system using two tubes the arc in one can act as the extinguishing means for the arc in the other.

Title: Improved rollstand equipment for unwinding and rewinding web material
Inventor: LIGHTON JOHN WILLIAM
IPC: B65H19/00
Filed: 1963-04-10
Abstract: 1,075,852. Feeding webs. FULLER ELECTRIC Ltd. April 9, 1964 [April 10, 1963], No. 14300/63. Heading B6B. [Also in Division G3] In reel-stand apparatus for winding or unwinding a web, control apparatus is provided to match the peripheral speed of a web-roll core or a web-roll with the linear speed of a running web prior to splicing. The Figure illustrates unwinding apparatus. A replacement web-roll 15 is driven by an electric motor 7. A tachometer 17 driven by the web-roll spindle or the motor 7 provides a voltage output directly proportional to the angular velocity of the web-roll 15. Alternatively, a voltage directly proportional to the angular velocity may be taken from the armature of the motor 7. A tachometer 29 driven by a roller 13 over which the running web 11 passes, provides a voltage directly proportional to the linear velocity of the running web 11. Alternatively, a voltage proportional to the web speed may be taken from the armature of a motor driving a web roller. A motor 6 is used to rotate the reel-stand 1 from the position shown in full line to the splicing position shown in broken line. A suitable detector 16 such as a photo-electric device or an ultrasonic sound beam device stops the rotation of the reelstand in the splicing position. Coupled to the shaft of the reel-stand via gearing 28 is a cam 21. A cam follower 25 which has a rack 24 engaging a pinion 27 moves a contact 23 of a potentiometer, the terminals 18 and 19 of which are supplied with the voltage from tachometer 17 which is directly proportional to the angular velocity of web roll 15. Movement of the contact is directly proportional to the diameter of web roll 15, therefore the voltage difference at the contact 23 is directly proportional to the peripheral velocity of the web-roll 15. This latter voltage together with the voltage from tachometer 29 proportional to the running web speed, is applied to a regulator 30. The regulator controls the field windings of a generator 32 which in turn supplies the electric motor 7 driving the web-roll 15.
Patent GB-143233-A (GB)
Abstract: 143,233. Odhner, V. J. May 14, 1919, [Convention date]. Transfer mechanism.-Relates to apparatus of the pin-wheel and cam-disk type as described in Specification 125,974, and consists in arranging the transfer actuating teeth of the pin wheel to move in the plane of the wheel. According to one construction, a part having two arms 3, 4 in different planes parallel to the wheel 1 is pivoted in the pin-wheel at 2, and is normally held in the position shown in Fig. 1 by a spring 5. When the sliding transfer trip member 6 is moved to its operative position, Fig. 3, by the transfer tooth on the lower wheel, the arm 4 is depressed, and the arm 3, which acts as the transfer actuating- tooth, is brought into its operative position. Modifications are described in which the transferactuating tooth is moved by the depression of another part by the transfer slide 6 through the intermediary of a rack and pinion or of a balanced lever. In a further modification, the depression of one arm of a pivoted two-arm part by the transfer slide 6 causes a pin on the other arm to move a plate which raises the transfer-actuating tooth by reason of a slot in the plate engaging a projecting pin formed on the tooth itself. Provision may be made for unlocking the Genevawheel attached to the receiving-wheel of the totalizing counter, thus a pin 24 on the arm 4 engaging a slot. 25 moves a plate 23 pivoted at 22 when the arm 3 is raised to the operative position, Fig, 11, and uncovers an opening 21 in the pin-wheel 1, allowing the passage of the star wheel 19, normally locking the receiving pinion, which is locked by the plate 23 when the arm 3 returns to its inoperative position. The other modifications for moving the arm 3 are also shown in combination with a plate for uncovering the opening 21 and permitting the receiving pinion to be unlocked during the transfer actuation only.

Abstract: 562,131. Control systems for welding arcs. RIMMINGTON, F. Oct. 14, 1942, Nos. 14377/42, 14764/42, 2103/43 and 10946/43. [Class 38 (iv)] Manual variation of the length of a welding arc is adapted to cause the selective operation of relays R1 ... R4 in a circuit 3, 4 shunted on the arc, whereby the output of a current supply generator G or transformer is adjusted. A reversible motor M may thus operate a current controller C in opposite directions in accordance with a temporary shortening or lengthening of the arc by the operator. Relays may be included whereby the motor is rendered inoperative on the shorting and opening of the arc circuit, and limit switches A, B, which may be jointly or individually adjustable with manual adjustment of the current controller, may be included in the relay circuit. According to Fig. 1 the relay R1 operates at 10 volts, relay R2 at 20-25 volts (during normal arc conditions) relay R3 at 37 volts and relay R4 when the arc is broken. In a modification relays R1, R3 are latched in when first caused to operate and the operator, after watching the effect on the arc, unlatches them, when satisfied, by a second movement of the electrode. In a further alternative, or in association with the last arrangement, the relay may have an adjustable time delay which determines the period of operation of the motor at each actuation. Modifications using an A.C. motor and a rectified current supply to the arc are described. The arrangement may be such as to effect a step-by-step operation of controller and motor. Specification 450,141 is referred to.

Abstract: 1535413 Electro - anaesthesia apparatus MOSKOV OBLAST N I INST AKUSHERST I GINEKOLOG 9 April 1976 14645/76 Heading A5R Electro-anaesthesia apparatus has a current pulse generator 1, means 3 for adjusting the pulse width, means 5 for adjusting the current amplitude of the pulses, means 6 for indicating the mean output current, and a patient protection circuit 7 which discontinues application of the current pulses to the patient if the output current amplitude exceeds a predetermined value. Circuit 1 comprises a multivibrator 20, 21 giving a square wave output at a p.r.f. set by adjustable resistor 29 of 100 Hz to 7 KHz. Circuit 2 acts to differentiate this output and gives 0.05 n sec pulses at the p.r.f. set in circuit 1 to a multivibrator 39, 40 circuit 3 giving an output at the same p.r.f. and having an adjustable resistor 46 to select the pulse width. A pulse shaper circuit 4 processes the output of circuit 3 and has a switch 65 to select either a square wave output, formed by differential amplifier 50, 51, or a pulse shape with an exponential trailing edge, formed by tranistor 60 and associated components. The selected pulse output passes to circuit 5 which is formed as a voltage generator and includes an adjustable resistor 68 to set the current amplitude of the pulses. The output of circuit 5 passes to the patient via a mean current indicating meter 79 of circuit 6. Circuits 1, 2, 3 &c. receive power from a battery 113 via a voltage stabilizer 106 to 110, and an inverter 96, 97, 102 and rectifier 103 give a supply at a second voltage to circuits 4, 5, 8. The output to the patient is monitored by a circuit 8, constructed as a peak voltage detector and having a peak current indicating meter 94, and by the circuit 7 which has a relay 83 which when the output current exceeds a preset level opens a switch 112 to disconnect the battery. In a modification, Fig. 7 (not shown), the input to circuit 5 may be connected to the output of circuit 2 selectively either via circuits 3 and 4 to give a continuous pulse train output or via a circuit (18) comprising a J-K flip-flop to give intermittent analgesia.
