Title: Improvements in or relating to reels, pulleys, wheels, drums and the like
IPC: B21D53/16
Filed: 1959-04-29
Abstract: 895,908. Corrugating. HILL, J. July 11, 1960 [April 29, 1959], No. 14573/59. Classes 83 (2) and 83 (4). A method of manufacturing an end or cheek of a reel, pulley, wheel, drum or the like from a blank consisting of a flat strip of rigid material is characterized in that the steps of forming folds of tapering depth in the blank and bending it into annular shape are performed simultaneously. A strip 10 is fed between dies 11, 12, intermittently brought together, shaped to form a fold 15 of constant width but of a gradually decreasing depth from one endge 16 to the other edge 17. A succession of these folds 15 cause the strip to assume an annular corrugated form. In a modification, Figs. 5 and 7, an upper die blade 19 is of constant width and gradually decreasing depth but a lower die recess 21 has a decreasing width and constant depth. A strip of metal 22 is thus formed to a corrugated annulus with folds 23 of narrow width and substantial depth at one end and greater width and shallower depth at the other end.

Title: Improvements in or relating to ultra high frequency electron discharge arrangements
IPC: H03B13/00
Filed: 1937-05-26
Abstract: 488,747. Cathode ray tubes. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. May 26, 1937, No. 14646. Convention date, May 26, 1936. Addition to 477,668. [Class 39 (i)] An electron - discharge device suitable for very high - frequency oscillations has an electron beam which is rotationally deflected in accordance with input or control potentials or currents and is caused to give up its energy of deflectional movement by electrostatic influence or magnetic induction upon transverse coupling - out fields, the elements between which the coupling-out fields extend being situated wholly outside the closed curved path of the beam and the fields being so arranged that a plurality of outputs in desired phase relation is obtained. As shown the beam from cathode K is deflected circularly by two perpendicular pairs of plates P<1>1, P<11>1 and P<1>2, P<11>2 having applied potentials in quadrature and passes between two perpendicular pairs of coupling-out plates P<1>3, P<11>3 and P<1>4, P<11>4 to which it imparts oscillatory energy before striking the collector A. Since the plates are influenced only by motion perpendicular to them, two outputs in quadrature are obtained. By coupling each output circuit back to the correct deflecting plates, self-oscillation may be produced ; or a single output may be coupled back to both plates through a phasesplitting network. A three-phase output circuit is described. In a modification, the rotary motion of the beam may be obtained by feeding the input plates in the same phase but displacing one pair along the beam so that the finite velocity of the electrons introduces the desired phase difference. The different pairs of coupling-out plates may be displaced along the beam and may then be parallel to each other ; or combinations of parallel and crossed fields may be used.

Title: Noise control circuit for angular velocity modulation receivers
IPC: H03G3/26
Filed: 1942-10-21
Abstract: 558,877. Wireless receiving circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 21, 1942, No. 14793. Convention date, Oct. 22, 1941. [Class 40 (v)] In a receiver for angular velocity modulated waves having an amplitude limiter followed by a demodulation stage, the amplitude limiter is rendered incapable of transmitting electrical impulses when the carrier falls below a predetermined amplitude. The Figure shows a phasemodulation receiver in which the signal from an I.F. transformer 2 is fed to a limiter valve 3 and thence to a discriminator-rectifier and subsequent stages, not shown. The transformer 2 also feeds a rectifier 6 and a voltage from the positive end of a load resistance 10 is taken through resistance 13 and polarity reversing means (not shown) for automatic gain control. The positive voltage across resistance 10 is also applied to the grid of a valve 20, in the anode circuit of which is a relay 26 controlling the screen potential of the limiter valve 3. The valve 20 is biased by potential divider 22, 24 so arranged that the grid is always negative and becomes more negative when the signal strength declines. This releases relay 26 to break the supply to the screen grid of valve 3 thus disabling the valve. An instrument I in the rectifier circuit indicates whether the signal is operative or not. The amount of amplitude modulation present may be determined by amplitude monitoring means connected to terminals 60.

Abstract: 559,608. Photographic sensitive material. JOHNSON, MATTHEY & CO., Ltd., BOX, E. R., and KERRIDGE, F. E. Oct. 27, 1942, No. 15051. Drawings to Specification. [Class 98 (ii)] Photographic sensitive material, particularly for use in the production of stencils, comprises thin water-insoluble flexible transparent support coated successively with a layer of heat-softening material which is at least semi-transparent and a colloid layer capable of being rendered lightsensitive. The support may be plasticized cellulose ether or ester or natural or synthetic resin. The intermediate layer may be wax, vinyl resin, or shellac, or other natural or synthetic resin. The colloid layer may be gelatin or glue, may be plasticized, and may contain a pigment or dye; the layer may be sensitized with a chromate or dichromate solution. A positive is printed on to the material through the uncoated side and the unexposed soluble colloid is removed by immersing the material in warm water. The material is cooled in cold water, the image pressed on to a silk screen and the backing removed by warming the screen or ironing the backing. A solvent for the intermediate layer may be applied before applying heat. Traces of the intermediate layer remaining on the screen may be removed by a solvent. The known process is referred to in which porous backing paper coated with gelatin containing carbon black is sensitized with dichromate solution and in which after exposure the gelatin layer is transferred to a waxed and glazed temporary paper support for development in warm water and then after cooling transferred to the silk screen and the temporary support removed. Specification 13093/02, [Class 98], is referred to.

A machine tool incorporating automatic tool changing means comprises a tool carriage 4 and support 5 movable over a first path towards and away from a workpiece secured in the machine, a conveyer device 8 supporting a number of tool carrier units 6A, 6B &c. and movable to convey these units over a second path which intersects the first path at a transfer station. Any selected one of the tool carrier units is transferred from the conveying device to the tool carriage by means operable on movement of the carriage past the transfer station the unit being transferred back to the conveyer device on reverse movement of the carriage past the transfer station. The conveying device may be in the form of a disc 9 rotatable about a horizontal or vertical axis having tool carrier units positioned around its periphery, or a rectilinear conveyer member 16, 17 coincident with the second path having the tool units linearly spaced thereon. The tool units are each secured to the conveyer device by spring-biased pivoted latches 25 mounted on the device which engage studs on the tool unit. When a particular unit is indexed to the transfer position the tool carriage is moved along the first path to the transfer position whereat cam means 47a, Fig. 7 (not shown), on a head portion 47 of the tool support 5 releases the latches 25 on the conveyer device and the tool unit is removed from the conveyer on to the tool carriage. This transfer means includes a fluid actuated tool unit locking means 36 which holds the tool unit securely on the tool carriage during its movement up to the workpiece and during its operation. The return movement of the tool carriage then permits by the same action the release of the fluid actuated locking means and the latching of the used tool unit back on to the conveyer device which is then indexed so as to bring the next tool required into the transfer station for a similar transfer operation. The conveyer device may be indexed manually or automatically.
