Title: Improvements in or relating to voltage regulators
Inventor: MUNNS SIDNEY ALBERT
IPC: H02P9/32
Filed: 1953-12-04
Abstract: 770,437. Automatic voltage control systems; alternators. MACKIE & CO., Ltd., W. Nov. 24, 1954 [Dec. 4, 1953], No. 33827/53. Classes 35 and 38 (4). In an automatic voltage control system for a self-excited alternator, the output voltage is rectified, compared with a reference neon to obtain a control signal for a magnetic amplifier which controls the current from the alternator to its field rectifier, and a relay is provided to short-circuit the magnetic amplifier or connect in an auxiliary D.C. supply when starting. The output of the alternator (not shown) is applied via auto-transformer 53 and rectifier 54 to a bridge consisting of neon tube 57 and resistors 58, 60, 61, 62. The control winding 63 of a magnetic amplifier 64 is connected across the other diagonal of the bridge. Amplifier 64 controls a second amplifier 69 which controls the current from transformer 77 to the rectifier 78 supplying the field of the alternator, connected at 79, 80. Winding 70 on amplifier 64 provides positive feedback, being in series with the control winding of amplifier 69; and winding 81 aids stability by being connected via condenser 82 across the output of rectifier 78. To enable the alternator to build-up at starting, the coil of a relay 93 is connected across the voltage detector bridge so that at low output voltages an auxiliary supply connected at 84, 85 is connected (via a thermal cut-out 89) to a rectifier 90, and the output of rectifier 90 is connected in parallel with the field rectifier 78 to the field terminals 79, 80. In a modification, Fig. 1 (not shown), only one stage of magnetic amplification is used, and instead of switching in an auxiliary field supply, the voltage sensitive relay shorts out the A.C. winding of the magnetic amplifier. It is also stated that instead of an A.C. generator, a D.C. generator, rotary transformer or rotary converter can be controlled; that the supply for the field rectifier may be derived from an auxiliary alternator coupled to the main generator; that the output of the final magnetic amplifier, instead of being rectified, can be added to the A.C. input or output of a rotary converter; that the voltage-sensitive bridge may include more than one constant voltage tube.

Title: Improvements in textile fabrics and methods and apparatus for treating the same
IPC: D03J1/00
Filed: 1955-11-25
Abstract: 789,261. Shrinking fabrics. WALTON, R. R. Nov. 25, 1955 [Dec. 9, 1954], No. 33848/55. Class 42 (1). A web of textile fabric is compacted longitudinally by feeding it at a first speed up to a fixed line of advance close to a line of first engagement with a frictional gripping surface moving at a lower speed; between the two lines the fabric is in a zone of speed change wherein it is laterally unconfined, but the two lines are so spaced that the material between them at any instant has a " columnar " rigidity preventing its accumulating into detrimental pleating and ensuring continuous longitudinal compacting. As shown, Fig. 5, fabric F is fed into the nip of pressure rolls D, T of which roll T rotates at a lower surface speed than roll D and has a higher coefficient of friction with the fabric. The retardation force applied by roll T to the fabric is resisted by a forward feed force applied at the line Np where the fabric is nipped against the surface of roll D by a stationary fabric indentor. These forces produce compression of the fabric over an unsupported columnar length l which is short enough to resist pleating or buckling. It is stated that as the length l is decreased (e.g. below 1 inch) the tendency of the fabric to pleat increases to a peak at a critical value of l of the order of 0.3 to 0.4 inch and then falls steeply to zero as l approaches zero; in practicing the invention l is selected within the range below the critical value so as to avoid pleating. The spacing of rolls D, T at the nip can be varied; roll T is carried in shoes 30, Fig. 2, vertically adjustable by means of worm gearing controlled by a hand wheel 44a, while roll D is pressed downwardly by air cylinders 32, downward travel being limited by engagement of screws 29, 31 against stops 13, 15. The indentor element 44 is carried slidably in side frames 49 suspended by links 43, 45 from frame members 41. Link 43 can be pivoted at 43a, by worm gearing operated by a hand wheel 70, so as to swing element 44 towards or away from the roll nip; the radius of turning of the links equals the radius of roll D so that the edge of element 44 follows the periphery of roll D. In addition, element 44 can be adjusted in a horizontal plane by means of threaded shafts 57 acting on the two sides of element 44 and operable independently by means of a hand wheel 62. Indicators M, M<SP>1</SP>, M<SP>11</SP> are provided in connection with the various adjusting mechanisms. Steaming apparatus is provided for moistening the fabric prior to the compressive shrinkage treatment.

Filed: 1929-11-07
Abstract: 338,713. General Electric Co., Ltd., (Assignees of Patent-Treuhand-Ges. f³r Elektrische Gl³hlampen). Jan. 21, 1929, [Convention date]. Low - pressure metallic - vapour apparatus: vacuum tubes. - A luminous electric discharge tube having a gas filling, more particularly of a rare gas, is provided with a sealed reservoir having a reserve supply of gas at a higher pressure, the reservoir being provided at the end nearer the luminous tube with a closure member which can be fused readily on being heated and thus admits the gas into the tube. In one form a tube 1 with electrodes 2, 3 has a lateral extension 8 connected to a small glass reservoir 9 which has a capillary tube 10 leading into the extension 8 and is closed hermetically by a plug 11 of a readily fusible metal alloy such as Wood's metal. A foot tube 12 with a pinch 13 and a small exhaust tube 14 facilitates the exhaustion of the reservoir 9 and the introduction of the reserve gas, the tube 14 being subsequently sealed off in known manner. Towards the end of the normal life of the tube the reserve gas is admitted by fusing the plug 11, for example, by a gas jet or electric heating ring. In another form the reserve gas is contained in a glass reservoir which has a thin, blown-out, domed portion extending into a lateral extension of the luminous tube, and a heating-filament disposed immediatelv beneath the dome is connected to two leading-in wires extending through a. pinch at the bottom of the reservoir. By passing current through the filament the thin dome is softened and is blown out by the, pressure of the gas beneath it. A tube may be provided with several extensions connected to sealed gas reservoirs. The current through the heating- filament may be switched on either manually or automatically. In the latter instance the switching is effected by the change in the current loading arising from the consumption of the gas contained in the tube.

Title: A case combined with a conception period calculator
Filed: 1955-11-28
Abstract: 780,296. Calculating-apparatus. NAULET, L. E. H. Nov. 28, 1955 [Nov. 27, 1954; Feb. 19, 1955], No. 34015/55. Class 106 (1). A device for determining the fertile periods of women is combined with a box and comprises a rotatable member bearing several scales corresponding to menstrual cycles of different lengths and each specially marked (e.g. by shading) to indicate the fertile period within that cycle, the scales co-operating with an evenly divided scale of the 365 days in a year. In one arrangement, Fig. 1, the menstrual cycle scales 14 are carried by a flanged ring 6 and the year scale 13 by a similar ring 4. The two rings are rotatable on the box and have inter-engaging teeth 7 to retain them in any set relative position. They are preferably transparent for co-operation with an index (not shown) on the box so that having set the appropriate menstrual cycle scale 14 in accordance with a commencement date on the scale 13, the two scales may be moved together in order to set the end of the cycle against the index. The appropriate cycle scale 14 may then be re-set with its commencement at this point. In a modification, Fig. 4, the year scale is marked on the bottom of the box 1 and the menstrual cycle scales on a disc 16. The two members are formed with inter-engaging teeth 7 which are disengaged for setting purposes by outward movement of the disc 16 under the action of a spring 20 when a screw 17 is slackened. Recesses 21 facilitate rotation of the disc 16.

IPC: G01P1/12
Filed: 1959-11-09
Abstract: 931,409. Impact-recording devices. PRINTING, PACKAGING & ALLIED TRADES RESEARCH ASSOCIATION. Jan. 16, 1961 [Nov. 9, 1959], No. 34375/59. Classes 106 (2), 106 (3) and 106 (4). An impact - recording device comprises mechanically- or electrically-operated mechanism moving a roll of recording paper at a predetermined constant speed, a set of shock responsive elements each coupled to a stylus and together producing a continuous record on the paper of shock in any direction, and further shock-responsive means adapted, on receipt of shock, momentarily to impart additional accelerating movement to the paper to expand the time scale marked off on the paper by an independently-operated stylus. As shown, the waxed recording paper 9, feed-roller 6, magazine roller 7, take-up roller 8, time-marking stylus 48 and the first set of shock-responsive elements 14, 15, 16 each provided with a stylus 18, 19 and 20, respectively, are housed in a casing 1 mounted in a container 3 which is placed in a package the transit hazards of which are to be investigated. A clockwork motor 4 drives via gearing 49, the feed roller 6 and a circular toothed plate 51 rhythmically depressing a spring-loaded rod 30 carrying the stylus 48. A belt 13 drives the take-up roller 8 slightly faster than feed roller 6 to keep the paper taut. The styli 18, 19, 20 are carried on rotatable pillars 21, 22, 23, respectively, which also carry counterweights 25 each producing a gravitational torque about a different one of three mutually perpendicular axes, the displacement amplitude of the styli being limited by springs 24. The feed roller 6 is rigid with milled driving wheels 41 which can be engaged so as to increase the rate of rotation, by either of a pair of pawls such as 40 (Fig. 3) each pair (there are three) being mounted on plates 37, 42, 43, respectively. The plate 37 moves in the y-z plane against springs 38 for impact in the xdirection such impact pivoting an arm 32, loaded with a mass 31 and constrained by spring 35, about a spindle 33 carried between pillars 34, a linkage 36 then moving plate 37. Plates 42 and 43 move orthogonally under their own weight for impact components in the y-z plane, the associated pawls acting on a common milled wheel 41. One pawl of a pair is active for each sense of movement of the associated plate, the pawl that was inactive during movement in a particular sense becoming active during the return movement of the plate caused by the springs 38, and the acceleration on the feed-roller is always in the same sense. A similar twin-pawl and ratchet arrangement between the circular plate 51 and a milled wheel 52 allows acceleration of the feed-roller without interfering in the clockwork drive to the timing stylus.

Abstract: 1278696 Vibratory pokers CEMENTATION CO Ltd 8 July 1969 34469/69 Heading B1C [Also in Division F2] Two bodies la, 1b, are inter-connected by a vibration-isolating coupling comprising set of three or more linkages each of which consists of a rigid link 2 with a rubber bush or like resilient element 3 at each end. On each body the three connection points (or, if there are more than three, three of them) are triangularly disposed-i.e. non-colinear. Fig. 2, which is a section on the line A-A of Fig. 1, shows a preferred arrangement for use when the number of linkages is 4. The arrangment is such as to allow the movement of one of the bodies with respect to the other to be the type of orbital movement arising in a vibroflot-viz. an apparatus for compacting soil to prepare a building's foundations. The vibroflot includes a tube which is driven into the ground whilst its lower end is vibrated orbitally (the tube as a whole not rotating): the effect of this is to cause soil settlement beneath the tube and, when the tube is subsequently withdrawn, loose material is shaken into the hole. In such an apparatus, the body 1a of Fig. 1 would be the main tube section and 1b the vibrated end section. The inner tube 6 of Fig. 2 is flexible and is employed to convey power supplies and water to the vibrating end of the main tube.
