Title: Dynamic phonograph pick-up
IPC: H04R1/16
Filed: 1944-09-11
Abstract: 586,979. Gramophone pick - ups. PHILCO RADIO & TELEVISION CORPORATION. Sept. 11, 1944, No. 17341. Convention date, Sept. 11, 1943. [Class 40 (iv)] [Also in Group XXXVI] A gramophone pick'-up of the moving-coil type comprises a coil-supporting member encircling and spaced from a supporting element carrying resilient means which engages the coil-supporting member at opposite points to provide resilient pivots for the coil-supporting member provided with a stylus whereby the coil is oscillated in a flux-traversed gap produced by a magnetic field structure. The pickup can be used alternatively for lateral-cut or hill-and-dale records by adjustment of the magnet system. The coil 22 carried by the cylindrical portion 19a of a member 19, of thin sheet material such as aluminium or parchment paper, having a conical portion 19b carrying a stylus 3, is oscillated in a gap formed between an enlarged portion of a centre polepiece 6<1> and polepieces 7, 8 associated with permanentlymagnetized blocks 10, 11, the latter block being adjustably secured by a bolt 16 to a non- magnetic spacer block 9, e.g. of brass. The coil supporting member 19 frictionally engages two blocks 25, 26 of soft rubber which are cemented into slots cut in the member 6<1>, and leave bevelled ends conforming to the conical portion 19b and extending below the member 61. The pick-up can be changed from lateralcut operation to hill-and-dale operation by rotating the magnetized block 11 through 180 degrees. In a modification, Figs. 8, 9, 10 (not shown), the blocks 25, 26 are replaced by a single U-shaped block located in a diametral plane of the member 6<1>. In a further modification, Figs. 12, 13 a single block 29 is secured in a slot 30 with enlarged ends merging into longitudinal slots 31, 32. This arrangement increases the vertical resilience of the mounting and enables a less resilient rubber to be employed. In a further modification, Figs. 14, 15, 18, limited to operation with lateral-cut recording the coil-supporting member 5, including the stylus 3 and the coil 22 is supported on resilient blocks 33, 34 located in recesses in the pole member 35 which is formed with an extension 35a located in a spacer block 36 of non-magnetic material. A permanentlymagnetized block 37 is secured to pole-pieces 40, 41 having extensions 40<1>, 41<1> which, together with the pole-piece 35 form the gap for the coil 22. Portions of the length of the leads 47, 48 from the coil 22 to terminal tags 45, 46 are encased between thick parchment paper laminae 49, 50 cemented together and forming a stiffened ribbon conductor 44, having its upper part 51 attached by adhesive to the block 36 and having its lower part curved and terminating in a straight portion 52, the ribbon being effective to damp movement of the member 5 greater than that occasioned by the grooves of the record.

Divided on 412,557 under which a Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 10, 1932. Drawings to Specification. [Class 100 (iv).] Relay type-wheel actions.-A typewriter having electrical means for rotating and swinging a type-carrier, to effect type-selection and impression respectively, comprises the following features :-Electromagnets for swinging the type-carrier are energized before the beginning of the swinging movement but are restrained until the rotary movement is nearly complete, the arrangement enabling the electromagnets to exert their full power at the beginning of the swinging movement. The restraining-means may consist of an arm which normally prevents the type-carrier from swinging, and is released by means of the differential-stop mechanism of the type-carrier. The stop-mechanism may be arranged also to close the circuits of the swinging-electromagnets. A yielding spring- connection may be arranged between the swinging-electromagnets and the type-carrier. To adjust impression, means may be provided for varying the time at which the circuit of the swinging-electromagnets is broken, and this means may be employed causing characters of large surface to be more forcibly impressed than characters of small surface. The electromagnets may have rotary armatures which are so arranged that the maximum torque occurs at the beginning of the movement. The swinging-electromagnets may be replaced by a spring which is tensioned by an electromagnet for returning the type-carrier. The description in the Specification is identical with part of Specification 407,949, but the claims are different.

Title: Improvements relating to iron-chromium alloys
IPC: C21C7/00
Filed: 1935-06-20
Abstract: In a method of making iron-chromium alloys, a charge comprising iron scrap, iron oxide, and a material rich in chromium, which may be high-carbon ferro-chrome, or chrome ore, or both, with or without chrome-iron scrap, is melted in an electric arc furnace for the production of a bath of low-carbon iron-chromium alloy and an overlying blanket of slag; the bath of alloy is withdrawn from the furnace for refining in a second furnace, and the oxides of iron and chromium in the slag are reduced, for example, by silicon, for the production of a second alloy rich in chromium. After the withdrawal of the first product from the melting furnace, some iron scrap may be melted on the slag to form a bath for the reception of the iron and chromium afterwards reduced from the slag.  The method is particularly applicable for the utilization of scrap containing chromium and one or more metals such as nickel, copper, molybdenum, tungsten, cobalt, &c., less readily oxidizable than chromium, in which case the first alloy withdrawn from the furnace contains substantially all the nickel &c.  The electric arc melting furnace used may have a chromite bottom, and the refining furnace may be an electric arc furnace with a magnesite lining.  In some cases the second product of the first furnace may be added to the metal bath in the second furnace prior to the refining operation.  The production of two products containing respectively (1) 8-10 per cent of chromium, 8-10 per cent of nickel, and 0,7 per cent of carbon, and (2) 12-14 per cent of chromium and 0,7 per cent of carbon, from a charge of chromium-nickel rustless iron scrap, low-carbon steel scrap, high-carbon ferrochrome, chrome ore, and roll scale, is described.
