Filed: 1924-10-27
Abstract: 243,139. Dubilier Condenser Co. (1921), Ltd., (Deventer, H. R. van). Oct. 27, 1924. Electromagnets.-An element for use in the manufacture of inductance coils or magnetic cores for transformers, electromagnets, or other electrical apparatus, consists of a sheet or strip of insulating material having a continuous layer, coating, or deposit of finely divided particles of iron or other material which is both electrically and magnetically conductive adhering to and evenly distributed over one or both surfaces thereof. The magnetic core comprises a plurality of such elements laminated, or the core may consist of a continuous conductive element wound into the form of a coil or spiral. Fibrous material such as paper is covered by the Schoop or other process with a continuous layer of iron dust which may be deposited in an atmosphere of nitrogen, carbon dioxide or some medium to prevent oxidation. One or both sides of the paper may be covered. After being covered, the element may be varnished or covered with other suitable non-conducting substance. To make a core, several such elements are laminated and bound together. The elements may consist of sheets of paper with a magnetic layer one side with or without a non-conducting coating. The coating may be produced by spreading a precipitate from a solution of a compound of iron o the magnetic particles may be precipitated directly on the sheet. Instead of laminations for magnetic cores, narrow strips of thin insulating material covered in the above manner with a layer of iron particles may be used, wound into a spiral. The spiral may also be used for the passage of electric current as a loading inductance coil in radio or in connection with electric signalling wherein a conducting wire is used between the transmitter and the receiver as distinct from radio methods. Instead of paper, cellulose such as used for making photographic films may be used. Specification 211,324, [Class 37, Electricity, Measuring &c.], is referred to.

Title: Improvements in pattern mechanism for knitting machines
IPC: D04B9/26
Filed: 1930-09-03
Abstract: 350,830. Knitting-machines. HEMPHILL CO., Central Falls, Rhode Island, U.S.A.-(Assignees of Lawson, R. H. ; Pawtucket, and Lovell, R. F. ; Providence, both in Rhode Island, U.S.A.) Sept. 3, 1930, No. 26282. Convention date, Sept. 16, 1929. [Class 74 (ii).] For selecting sinkers or web holders and/or needles for patterning, e.g. by reverse plating, drop-stitch effects or design in pile loop fabric, a pattern wheel is used comprising a dial 12 in which are mounted slidable two-part jacks 6. The two parts 7, 8 are hinged together and the sinkerengaging ends of the outer parts 7 are turned over. The inner parts 8 have butts 11 on which operate cams mounted in a stationary cap 14 while the parts 7 have butts 10 sliding in radial tricks of a ring 16. The parts 8 rest upon pins 18 which pass through the inclined walls 13<11> and rest on the cams 20 of a pattern drum 21. This drum can be racked, say, one step per course knitted. The pins can thus be raised at any time to lift the parts 8 of the corresponding jacks so that their butts 11 are operated by the cam cap 14. After the jacks have been projected and their companion sinkers have been thereby moved to reverse plating position they are retracted and either fall by gravity to the inactive position or are pushed down by a cam. Alternatively the pins 18 may be divided into series each series being controlled by a rotating drum &c. having lugs &c. extending along it in an arc of a circle. The jacks 6 instead of acting on sinkers may act on independent instruments mounted below the sinkers, these instruments when acted on pushing the needles inwards to effect reversal of the plating. The jacks may act directly on the needles in which case they are mounted to slide radially in the sinker bed and have long projecting members 52 provided with lateral needle engaging projections 56. The outer ends have upper butts 54 and a line of depending butts 55 any of which may be removed. The butts 55 are first selected by the action of pattern controlled plungers and the movement is completed by cams acting on the butts 54. Specifications 278,383, 288,994 and 291,091, [all in Class 74 (ii), Knitting &c.], are referred to.
