Title: Improvements in permanently applied brakes particularly applicable for braking spindles
IPC: H01F41/094
Filed: 1945-09-24
Abstract: 591,892. Paying-out mechanism. SOPER, H. N., and JONES, G. V. WYNNE-. Sept. 24, 1945, No. 24683. [Class 120 (ii)] [Also in Group XXXIV] A brake for the spindle of a wire paying out mechanism of the type in which a flyer rotates about a fixed bobbin, has means by which the braking effort may be varied to vary the tension so that the mechanism may be adapted for varying gauges of wire. The 'brake comprises a flat spiral spring 18 secured at its inner end to the rotating spindle 4 to be braked and bearing at its outer end on a drum-like friction member 11, 12 whose effective diameter may be varied to vary the braking effect. The drum-like member, comprising a spring 11 lined with friction material 12 passes at one end through a cut-away portion 9 of a fixed enclosing drum 7 and is anchored at 13 to a control plate 14 constrained by slot 21 and screw 23 to rotate relatively to the base 22 secured to the top of the bobbin. The other end 15 of the drum-like member 11, 12 is anchored to a guide 16 constrained by a radial slot and a screw 20 to slide radially relatively to the base 22 while a lug 180 on the guide 16 engages in a slot 17 in the plate 14 so that rotation of the plate 14 causes radial movement of the guide 16. The combined motion of the ends of the drum-like member causes a reduction in its effective diameter. A locking screw 19 for plate 14 may be provided and graduations on the base 22 may be uncovered by the plate 14 to indicate wire gauge numbers.

Abstract: 772,404. Turbines. VARIAN ASSOCIATES. Sept. 2, 1955 [Oct. 27, 1954], No. 25333/55. Class 110 (3). [Also in Groups XXXIV and XL (a)] To improve the extraction of heat from a nuclear reactor by means of a boiling liquid, the reactor is rotated about an axis whilst it is in operation, so that centrifugal force reduces the amount of liquid and solid particles ejected from the reactor with the vapour. Fissile material, e.g. enriched uranium, mixed with H 2 O or D 2 O is contained in a hollow oblate spheroid body 5 mounted on a shaft 1. Turbine blades 14 are secured to this shaft on either side of the reactor and steam from the reactor drives these blades to rotate the reactor and to drive a generator. When the reactor is started, it is empty of liquid (and fissile material) and this flows in through pipes 19 while a motor drives the shaft 1, and during operation condensate is returned through these pipes. When the reactor is operating, water in two annular troughs 9, 11, support the rotating parts, with the aid of fixed water-bearing surfaces 17<SP>11</SP>, Fig. 2. Steam leaving the reactor passes through spokes 6. In several modifications described, the reactor is driven by one set of turbine blades 67, the power turbine being on a separate shaft.

Abstract: 749,021. Deep-etched photo-mechanical printing plates. AKTIESELSKAPET CLICHE. Sept. 14, 1953 [Sept. 13, 1952], No. 25383/63. Addition to 721,873. Class 98 (2). The process of the parent Specification in which a metal plate coated with a light - sensitive resist layer is exposed through a line or half-tone image, processed to dissolve unexposed areas of the layer, provided with a second, different, light-sensitive resist layer, re-exposed through the same image during relative movement in a small closed circuit between the image and the plate, and again processed, to leave the second resist image areas superimposed upon and uniformly slightly larger than the first resist areas, followed by etching to the marginal boundaries of the first resist areas, is modified by the feature of effecting the relative movement in the form of a spiral whereby, particularly in the case of very small transparent dot areas of the original image, the second exposure is effective right up to the edges of the resist image produced from the first exposure. The difficulty so avoided is shown in Fig. 1 in which, highly magnified, a transparent dot 3<SP>1</SP> of the original image 1 which has produced a resist area 3 by the first exposure and processing, may, by merely circular movement between the image 1 and plate 2 during the second exposure, affect only a circular area of the second resist and leave an annular unexposed ring around the resist 3. Exposure is effected in contact, the image 1 and plate 2 being shown apart for clarity. An apparatus for providing the spiral relative movement between the image and the re-sensitized plate during the second exposure and shown diagrammatically in Fig. 3 comprises an axially revolvable arm 5, 6 oscillatable about a point 7, turnably connected at 8 as to the plate, and provided with an extension 13 rigidly connected to the lower end 6 and slightly out of line therewith. A sleeve 14 displaceable downwards to 14<SP>1</SP> shifts the extension 13 and hence the axis of revolution 15 of the arm 5, 6 to that shown at 12 and so produces the spiral movement 9 of the arm 5, 6 and hence the plate during displacement. Figs. 4, 5 (not shown) illustrate corresponding mechanisms including drive for successive up and down displacements of the sleeve 14.

Title: Improvements in and relating to winding machines
Inventor: MACKIE JOHN KAY PRINGLE
IPC: B65H59/36
Filed: 1955-09-08
Abstract: 826,914. Winding yarn; tension control. MACKIE & SONS Ltd., J. Sept. 7, 1956 [Sept. 8, 1955; March 8, 1956], Nos. 25761/55 and 7359/56. Class 120(2) A roll winding or cop winding machine in which yarn is drawn over end from spinning bobbins has a tensioner and a movable member (which may be part of the tensioner) which is under the influence of the tension in the yarn on the supply side of the tensioner and which is loaded so as to assume a normal position as long as that tension is below a predetermined limit but is moved thereby when the limit is exceeded and, in moving shortens the path of the yarn and decreases the drag imposed by the tensioner, the movable member being so mounted as to respond immediately to sudden changes of tension and to make correspondingly sudden and substantial changes in the drag. In the embodiment shown, yarn is unwound from package 20 and passed round a smooth pulley 58, over a stud 62 on a pivoted lever 64 and around a second stud 63 to a traverse drum 52 and cheese 53. When the tension rises above a limit determined by a spring on pivot 66 the lever 64 swings to the position shown in chain-dot lines, thus shortening the yarn path and reducing the wrap around the friction studs 62, 68. Should the tension fall too low or vanish, the arm 70 pivots to release a latch lever 80 and bring into action a stop motion. In a second embodiment the invention is applied to a copwinding machine wherein the tension is applied by a row of double-disc type tensioners, the degree of engagement with the yarn being varied by a pivoted lever over which the yarn passes. A further embodiment comprises two jaws spring urged together and each carrying several studs or rollers which interengage, one of the jaws acting as the movable member and controlling the interengagement of the studs or rollers. Specifications 804,791, 804,792 and 804,793 are referred to.
