Title: Improvements in the control of dynamo electric machines coupled to coiling reels and the like
IPC: B65H23/185
Filed: 1941-10-31
Abstract: 554,624. Automatic control systems for coiling machines. ENGLISH ELECTRIC CO., Ltd., CARNEGIE, H. S., ENGLISH, R. L., and TABB, R. P. E. Oct. 31, 1941, No. 14041. [Class 38 (iv)] Current; tension.-Where a D.C. dynamoelectric machine 1 is coupled to a reel for wire, strip &c., and has (1) its armature supplied from a basic voltage proportional to mill speed, and (2) its excitation automatically controlled to keep the tension constant and the armature current at a basic value, and (3) where a voltage component is added to the armature circuit in proportion to armature current and equal to the I.R. drop therein, as by a booster 5, a further voltage component is added to the armature circuit to vary the torque of the coiling machine in accordance with acceleration or retardation of the mill or reel and this may be accompanied by a corresponding change in the excitation control to give an additional current component 1.2 (in which case the further voltage component is equal to 1.2R). Fig. 1 shows an exciter 2 driven by the mill giving the basic armature circuit voltage (alternatives are described also), and a current regulator 3 operating on a resistance in the separate excitation. circuit of the machine 1. The excitation of the booster 5 is adjusted to give a voltage proportional to the armature current by coupling a rheostat 24 to the means for setting the regulator, e.g. to a rheostat 23 or 27, or by a series field on the booster. To obtain the further voltage component proportional to acceleration an auxiliary field winding 5a on the booster may carry the current in a circuit connected as in Specification 554,625 across a steady voltage 10 and comprising an exciter 6 coupled to the reel and a flywheel machine 8. This circuit may also excite a control winding on the regulator to produce the aforesaid current component I.2 during acceleration. As shown the regulator is controlled by a machine 21 as in the first and second Provisional Specifications of Specification 554,622, and a control winding 21 b. The excitation of the flywheel machine may be proportional to the current I which is maintained under steady speed, a field winding 8b thereof being subject to the regulator 3. In a modification, Fig. 2 (not shown), the winding 5a of the booster is excited in proportion to the product of speed and acceleration as by an exciter driven by the reel and itself excited by a winding connected as 5a in Fig. 1 ; in this case the winding 8b on the flywheel machine is omitted. The current component 1.2 or the basic voltage of the armature circuit may in addition vary in accordance with coil diameter. Specification 554,623 also is referred to.

Title: Process of producing colour pictures
IPC: G03C7/46
Filed: 1932-05-17
Abstract: 387,197. Toning ; colour photography 1. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. May 17, 1932, No. 14049. Convention date, May 16, 1931. [Class 98 (ii).] Azo dyestuff images are produced from metallic, e.g. silver images by converting the image into a sparingly soluble diazotate of the metal, coupling with an azo dye coupling component and, if desired, removing the metal, e.g. in a fixing bath. The process is applicable to layers on transparent supports such as regenerated cellulose films and may be applied to layers superimposed or arranged on opposite sides of a support. The coupling may be effected in acid or alkaline solution and the layer may be hardened prior to coupling. In examples a bleached silver image is treated with a solution of alpha-naphthalene sodium antidiazotate and coupled with 1 : 8-diaminonaphthalene or with H-acid. Other coupling components are resorcinol, 1-amino-8-naphthol-2:4-disulphonic acid and anthranilic acid in the presence of steam charged with acetic acid. In another example the bleached image is treated with dianisidine antidiazotate, coupled with H-acid and the silver removed with cupric chloride and thiosulphate. A bleached image in a metal other than silver, for example, one produced by treating the silver image with a copper intensifier may be used. The coupling component, e.g. #-naphthylamine may be incorporated in the unexposed emulsion which is bleached after exposure and treated with a diazotate, e.g. #-naphthyl sodium antidiazotate. Superimposed layers containing #-naphthylamine and methyl phenylpyrazolone respectively are exposed and the images bleached with copper chloride, combined with #-naphthylamine-antidiazotate and treated with acetic acid and sodium chloride giving red and yellow images respectively.

Abstract: 1,142,003. Cryogenic specimen mount for diffractometer. NATIONAL RESEARCH DEVELOPMENT CORP. 25 March, 1966 [2 April, 1965], No. 14138/65. Heading H5R. A specimen mount for an X-ray diffractometer particularly a diffractometer of the kind having a table rotatable about a vertical axis is equipped with a cryostat to maintain the specimens below room temperature during examination. A base member 29 (Fig. 2, not shown) which may be rigidly mounted on the rotatable table carries a carriage 28 which is adjustable with respect to the base member both translationally and rotationally and the carriage rigidly supports a cryostat on e.g. stand 23 of Fig. 1 so as to be disposed above the base member when the attachment is in use. The cryostat as shown in Fig. 1 comprises an enclosure 1 which may be evacuated and which contains a specimen mount 7 and a container 5 for refrigerant liquid which cools the mount and is arranged so as to be above the mount in relation to the base member. The specimen mount 7 consists of a metal block having a planar reference surface 8 which is perpendicular to the base member and parallel to the axis of rotation of the carriage, which axis also lies in said surface. The specimen is mounted (Figs. 3 and 4, not shown) in a suitable holder so as to have a plane surface aligned with and below the reference surface and so as to be in good thermal contact with the mount. A portion 4 of the enclosure is removable so as to render the specimen mount accessible and support 23 is so formed, e.g. of curved elements 24 and 25, so that in use a correctly mounted specimen is accessible to a horizontal beam of X-rays over a wide angle around the axis of rotation. If desired, the cryostat may contain a heat shield 12 disposed so as to surround container 5 and mount 7, said shield being cooled by refrigerant liquid from a second container 10. A portion 14 of the heat shield is detachable so as to render the specimen mount accessible. Preferably, the stand 23 is such so as to provide two clear spaces on either side of the reference plane 8 and the detachable portions 4, and 12 if fitted, are equipped with X-ray permeable windows extending over a wide angle around the rotational axis of the carriage and are disposable in alternative locations so that the windows coincide with one or other of the clear spaces. The specimen holder preferably carries several specimens in a part which is adjustable with respect to the rest of the holder so that each specimen may in turn be located in a position where it is exposed to the X-ray beam, the cryostat being provided with means, operable from outside the enclosure to move said part and position the specimens. The cryostat is fitted with appropriate temperature measuring devices.

Abstract: 1,065,423. Counter; selective signalling systems. E. S. MESSER. April 6, 1964 [April 5, 1963], No. 14151/64. Headings G4D and G4H. A counter. comprises a set of digit wheels 38, Figs. 3, 4, each wheel 38 having end faces which are profiled to co-operate with feelers 92 and provide, by closure of contacts 98, a four-bit parallel signal representing the position of the wheel. Feelers 92 are normally spring biased out of contact with wheels 38, and when an electrical read-out is required, a solenoid 158 is energized to force pins 110, Fig. 3, between members 108 which thereupon pivot about 106 and press fingers 92 in towards the respective wheels 38. Before solenoid 158 completes its stroke, the units wheel is indexed to display the nearest correct digit, this being achieved by a linkage 142, and a roller 136 which cooperates with a star-wheel 134 keyed to the units digit wheel. The input shaft 56 drives two sets of wheels 38, 28 through an idler gear. The counter comprising digit wheels 28 is used merely for display purposes, the wheels 28 being visible through a window 26. The counter comprising wheels 38 is visible through a window 36, has the electrical read-out facility above-described, and may also be reset at intervals to totalize events over given time periods, such events being for example the passage of vehicles past a given point. Resetting of wheels 38 is performed by energizing solenoid 86 so as to pivot a set of members 74 about shaft 78, members 74 co-operating with heart-shaped cams 88 keyed to the respective wheels 38. Printer control.-The coded output from switches 98 is applied to a relay decoding tree to energize one of solenoids (228), Fig. 16 (not shown). A yoke (206) is then rotated about shaft (212) and carries arms (218) with it, there being one arm (218) for each digit wheel. When an arm (218) engages a stop member (224 which is projected by the energized solenoid (228), the arm (218) is stopped, although yoke (206) is allowed to complete its sweep. Print wheels (170) are positioned by gears (198) coupled to arms (218). At the end of the scan by yoke (206), solenoid (194) is energized to raise print bar (172) to perform the printing operation. Ink ribbon (174) runs between spools (176, 178), switches (184, 186) being provided to reverse the direction of feed when either spool becomes full.

Title: An automatically operated voltage regulator
IPC: G05F1/648
Filed: 1923-05-31
Abstract: 210,346. Kinoshita, M., and Nobbs, W. W. May 31, 1923. Regulation, automatic.-In an automatic voltage regulator comprising a voltage relay, two auxiliary relays the circuits of which are closed selectively by the voltage relay, and a motor reversibly controlled by the auxiliary relays, the circuit of the auxiliary relay is maintained energized after the circuit closed by the primary relay is interrupted to avoid sparking at the contacts of the primary relay, and the circuit of the auxiliary relay is opened after a predetermined number of revolutions of the motor. The primary coil of the regulator is connected in series with a battery connected across a potentiometer resistance, and limiting switches are provided to stop the motor at definite positions of the switch-arm of the regulator. A voltage relay C, Fig. 3, closes the circuit of an auxiliary relay H<1> through the contacts c<1>, d<2> and switches W<1>, O upon a fall of potential across the mains 1, 2. The contacts k<1>, i<1> of the relay H<1> close the circuit of a motor M to operate a regulator arm B to reduce the resistance A, and a contact j<1> closes the circuit of the relay H<1> through parallel-connected contacts n<1>, n<2> and the magnet P of the switch O. The energization of the magnet P opens the circuit closed by the primary relay C in order that sparking may not occur at its contacts when the regulator operates to increase the potential to be regulated. A cam N, operated through gearing by the motor M, opens at the contacts n<1>, n<2> the circuit of the auxiliary relay H' after a predetermined number of revolutions to stop the motor M if the relay C has in the meantime moved to its neutral position. A rise in voltage causes the relay C to close the circuit of an auxiliary relay H<2> which operates in a similar manner to that of the relav H<1> to cause the motor M to revolve in the opposite direction to increase the resistance A. The coil G, Fig. 2, of the voltage relay may be placed in series with a battery F, across a resistance b<0>. Switches W<1>, W<2>, Figs. 3 and 4, are placed in the circuits closed by the relay C to stop the motor M at the end of travel of the regulator-arm B, which is driven through belt-gearing and worm-gearing.

Abstract: 401,751. Gramophones. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Elmer, L. A., 102, Riggs Place, West Orange, New Jersey, U.S.A.) May 23, 1932, No. 14598. Convention date, July 22,1931. [Class 40 (ii).] The effect of extraneous vibrations and the lateral component of the friction drag between the stylus of a pick-up on a pivoted arm and the record groove is compensated for by designing the arm and counterweighting its pivoted end so that a pivot axis for the arm passes through the centre of percussion of the device about an axis through the stylus point parallel to that axis, and by arranging a spring between the arm and a stationary support so that it balances the drag component. This spring may also be adjusted to regulate the pressure of the stylus on the record, or a separate spring may be used for this purpose. In Fig. 2 the arm 13 carrying the pick-up 12 and mounted between horizontal pivots 14 carried by a vertical pivot is so designed and weighted at 16 that its centre of percussion with reference to the stylus is near the pivot 14. A spring 17 extending between a bracket 20 on the arm and a fixed bracket 19 is arranged so that it is parallel with the axis of the arm when this is tangential to the groove engaged by the stylus but exerts a turning action on the arm in other positions to compensate for the lateral drag. The fixed bracket may be adjustable vertically so as to regulate the pressure of the stylus on the record.
