Filed: 1957-08-22
Abstract: 808,759. Winding webs. DORRIES, A. G., O. Aug. 22, 1957 [Sept. 21, 1956], No. 26586/57. Class 100(1) An apparatus for winding a web 13 of material, e.g. paper, comprises a winding cylinder 1, a driving disc 3 eccentrically mounted with respect to the cylinder 1, such that a portion only of the periphery of the driving disc extends outwardly of the cylinder, a driving connection between the disc and cylinder, such that they rotate at substantially equal peripheral speeds, a carrier 12 for a winding drum 11 movable between a position in which the drum 11 is in driving engagement with the disc and a position in which the drum is driven by the cylinder, whereby the drum is accelerated to a peripheral speed substantially equal to that of the cylinder prior to the web being wound on the drum. As shown, the disc 3 is mounted on an antifriction bearing 5 carried by an eccentric bush 6. The bush 6 is mounted for relative angular adjustment on a bearing 7 supporting the shaft 15 of the cylinder 1. The disc 3 rotates about an axis 10 displaced from the axis 9 of the cylinder 1, the disc being driven by a pin 2 projecting from the cylinder 1 into a slot 4 in the disc. The carrier 12 is rocked by a hydraulic or pneumatic cylinder 17, such that the drum 11 follows the path indicated by the arrow 18. When the drum reaches position B the shaft of the drum is received in bearings 16 movable along the frame 14. When winding is complete the shaft of the drum 11 is clear of the forked ends 12<1> of the carrier 12, thus allowing the carrier 12 to be moved into position A to receive a fresh winding drum 11 which is accelerated by the disc 3. The completed roll is then removed from the bearings 16 whilst the new drum 11 is moved to position C to commence winding.

Title: Improvements in or relating to spark-cutting apparatus
IPC: B23H1/00
Filed: 1952-10-23
Abstract: 737,397. Removing metal by spark discharge. METHOD X CO. Oct. 23, 1952 [Nov. 14, 1951], No. 26605/52. Class 83 (4). In apparatus for cutting a workpiece by repeated spark discharges across the gap between the work-piece and an electrode having a condenser across the gap a grid-controlled discharge tube is connected between the condenser and a source of charging current therefor, to isolate the condenser after charging thereof from the charging source until after the condenser has discharged and means are provided to render the tube conducting at a predetermined time after the condenser discharges. A condenser 2 supplied from a source 6 is connected one side to a manually adjustable electrode 32 maintained above a workpiece 22 in a dielectric liquid, e.g. kerosene or transformer oil, and the other side to the workpiece. A triode 3, e.g. a thyratron, is connected in one lead from the source 6 to the condenser in series with a pulseforming network 4 comprising a condenser 44, a resistor 46 and an inductor 42. The triode grid is connected to a delay device 5 comprising a simulated transmission line. A resistor 48 is joined between the triode grid and cathode. In operation with the condenser 2 charged and the triode deionized and non-conducting the electrode is advanced to the workpiece until the condenser discharges in a spark across the gap. The gap is deionized quickly since it is isolated from the source 6. As the condenser discharges an impulse from the device 5 is applied after a time delay to the triode grid. The triode fires and becomes conducting and the condenser 2 is charged from the source 6 through the triode. The triode is deionized by the network 4 when condenser 2 is charged.

Abstract: 634,890. Stereoscopic photography and kinematography. DUDLEY, L. P. C. J. Oct. 2, 1947, No. 26611. [Classes 97 (i) and 98 (ii)] An optical device constituting a temporary or permanent attachment fo a single-lens camera for use in the production of stereoscopic anaglyphs comprises spaced reflecting means and two complementary colour filters, one in association with each of the reflecting means, the arrangement being such that light from the object which passes through one colour filter is reflected by one of said reflecting means to form a latent image of the left-eye view of the object on a film or plate in the camera while light passing through the other filter is reflected by the other of said means to form on the film or plate a latent image of the right-eye view, which image is superimposed on that of the left-eye view. In the form shown in Fig. 1, the optical device comprises filters 1, 2 of complementary colours, a half-silvered mirror 3 and a frontsurfaced mirror 4. Mirror 3 transmits light from filter 1 and reflects to an equal extent the light from mirror 4, this light then passing through the camera lens 5 on to the photographic film or plate therein. Mirror 4 may be replaced by a 45 degree prism, while mirror 3 may be replaced by two 45 degree prisms with their hypotenuse faces in contact and with one of such faces half-silvered. These prisms may be joined as by cement to an intermediate block, as of glass; this block may also be made integral with the prism 4 and the 45 degree prism with the half-silvered hypotenuse face. In another form, the device may comprise filters 10, 13, Fig. 6, and mirror or prism pairs 11, 12 and 14, 15, respectively. The stereoscopic base may be adjusted by sliding one of the prisms relatively to the other as by a rack and pinion mechanism. Also, one of the prisms or mirrors may be pivoted about a vertical axis and such pivoted movement may be coupled to the focusing movement of the convex lens. Thus, mirror or prism 4, Fig. 1, may be attached to an arm capable of swinging on a rack as the latter is moved by a pinion attached to the focusing ring of the camera lens. The device may be carried in a housing which is secured by lugs to a bracket having a boss that threads into the usual lens holder of the camera; this housing may also carry a lens for substitution for the ordinary camera lens. The device may also be built into the camera.

Abstract: 407,634. Centrifugal separators. AKTIEBOLAGET SEPARATOR, 8, Fleming- gatan, Stockholm. Oct. 3, 1933, No. 27163. Convention date, Oct. 5, 1932. [Class 23.] A centrifugal separator, particularly for use in purifying oils, has a bowl 2 enclosed in a frame housing divided into two chambers 11, 12 by an annular wall 7 provided round the spindle 5, and a waste liquid outlet 13 leads from the chamber 11 inside the wall. The purified light component passes into the chamber 4 and the heavy component consisting of emulsified oil and water passes into the chamber 3. After the chamber 3 is filled, the emulsion is forced between the hood and the chamber 3 into the chamber 12, and its great viscosity prevents it from flowing through the tube 14. Eventually it stops the bowl, and the contents of the bowl flow out through the channels 8 and nozzles 9 to the chamber 11 from which they are discharged by the pipe 13. The annular wall 7 prevents the emulsion from reaching and clogging the pipe 13. The wall 7 may be cylindrical or conical, and has a flanged top. In a modification the portion of the housing situated inside the wall 7 is enlarged at its lower end, and extends below the part of the housing outside the wall.
