Filed: 1934-12-05
Abstract: 448,341. Frequency changing; phase changing. SIEMENS-SCHUCKERTWERKH AKT.-CES., Siemensstadt, Berlin. Dec. 5, 1934, Nos. 34962 and 34963. Convention dates, Dec. 5, 1933 and May 9, 1934. [Class 38 (ii)] Relates to a frequency - chanching arrangement for supplying a high speed motor from a 3-phase supply and consists in employing n saturated transformers the primary windings of which are arranged so that the fluxes generated are 60‹/n phase displaced from each other, the secondary windings being connected to the phase windings of the motor. In the form shown the transformers 6, 7 have open delta secondaries so that 3rd harmonic voltages only are present on the secondary side, and the primaries are respectively star and zigzag connected so that the 3rd harmonic voltages are 90‹ out of phase. Chokes 8 may be connected in series with the supply and condensers 9 in parallel. In addition condensers 10, 11 may be connected in series in the secondary circuits. In a modification the primaries of the two transformers are connected in series, and the cores united with a common yoke. In a modification the secondaries are suitably proportioned and arranged in Scott connection to give a three phase output. Condensers may be connected either in parallel with the secondary windings or in parallel with the 3-phase output. In a modification of this the windings are distributed over three three-limbed cores. In an alternative arrangement three transformers with primaries arranged to produce fluxes 20‹ phase displaced are employed to give a 3-phase output. Instead of employing an open delta secondary, a single winding arranged on the fourth limb of the core may be used.

Abstract: 207,712. Richardson, H. Dec. 23, 1922. Grab-buckets. - Relates to grabs in which a member 3 sliding relatively to the grab head is locked, when the grab is closed, to a lower member 4 connected with the buckets. For releasing the buckets from the member 3 in midair, a tripping-device for releasing the lock is operated by relative movement between the member 3 and the grab head. As shown, the grab is similar to that described in Specification 179,663. Angle levers 11 with hooked ends pivoted on the lower member 4 pass through an aperture in the member 3 and are held apart by a discharging lever 14, seen in end view, so as to lock the parts 3, 4 together, but the member 4 now forms the main cross-bar of the grab, and the member 3 forms a lower sheave-block cooperating with a block 1 on the grab head. The block 3 is provided with vertical guide-bars 10 which slide in guides 7 of H-section fixed to the cross-bar 4, these guides 7 sliding on bars 8 depending from the grab head. A weight 20 slides on a guide 21 secured to one of the bars 8, and rests on one end of a lever 18, of which the shorter weighted end 17 bears under the discharging lever 14. The lever 18 may be operated by a chain 19 for hand-dumping, or by the sliding weight 20 when the closed grab is lowered to the ground, as described in the prior Specification. The tripping device for releasing the lock in mid-air comprises a lever 22 pivoted on the cross-bar 4 at 23, and a pawl 24 on a bracket 25 secured to one of the guide-bars 8 on the grab head. For discharging, the grab is suspended from an opening rope secured to the grab head at 26, and on paying out the lifting rope, the block 3 and cross-bar fall, the lever 23 is caught by the pawl 24 and engages the end 17 of lever 18 so as to operate the discharging lever 14. The grab may be closed by paying out the lifting rope until the block 3 engages the cross-bar 4 and then hauling in. The sliding weight 20 may be dispensed with if discharging by dumping is not required. In a modification, shown in side elevation in Fig. 2, in which there is no provision for discharging by dumping or by hand, the lever 18 is omitted and the end of the discharging lever is tripped by engagement with a stirrup 28 pivotally suspended from a bracket 27 on the grab-bead.

Title: Process for producing fibrous polycarbonate material
IPC: D01F6/64
Filed: 1959-10-19
Abstract: Polycarbonate filaments are made by wet or dry spinning a solution having as its chief polymer component a linear fibre-forming polycarbonate synthesized chiefly from a 4,41-dihydroxy-di(mononuclear aryl) alkane in which the aryl groups are attached to the same carbon atom of the alkane, the intrinsic viscosity of the polycarbonate being from 0,48 to 1,14 (in methylene chloride at 20 DEG C.), and drawing the filaments so made to a draw ratio of 1:1,5 to 1:8 at a temperature of from 40 DEG -140 DEG C. The polycarbonate may be synthesized chiefly from 4 41-dihydroxy-diphenyl-2 2-propane, either by reacting phosgene with starting materials consisting chiefly of this substance in the presence of an acid-binding agent and a solvent, in which case the intrinsic viscosity of the polycarbonate is desirably 0,75-1,00, or by the esterinterchange reaction of similar starting materials with carbonic acid diesters, in which case the intrinsic viscosity of the polycarbonate is desirably 0,65-0,85.  The preferred polycarbonates are mixed or co-condensed polycarbonates synthesized from 4,41-dihydroxy-diphenyl-2,2-propane and 1-10%, especially 2-10%, of other dihydroxy compounds selected from other 4,41-dihydroxy-di(mononuclear aryl)alkanes in which the aryl groups are directly attached to the same carbon atom of the alkane, 4,41-dihydroxy-di(mononuclear aryl) sulphones, and 4,41-dihydroxy-di(mononuclear aryl) alkanes in which the aryl groups are directly attached to the same carbon atom of the alkane and which carry a carboxyl or sulphonic radical.  A long list of such starting materials is given.  Filaments may be made by wet spinning a solution of the polycarbonate, suitably in a chlorinated hydrocarbon solvent, especially methylene chloride or ethylene chloride, but alternatively in chlorobenzene, phenol, 1,4-dioxane or dimethyl formamide, into a coagulating bath of an aliphatic hydrocarbon, or of a mixture of an aliphatic hydrocarbon and a chlorinated hydrocarbon.  Ligroin, mineral spirits and kerosene are specified.  Filaments may also be made by dry spinning a solution of the polycarbonate in the solvents specified, especially a solution in methylene chloride, ethylene chloride, chlorobenzene, 1,4-dioxane and mixtures thereof, into an evaporative atmosphere.  Conventional additives, e.g. delustrants, pigments, and other soluble polymers which improve the dye affinity or moisture absorption of the fibres may be added to the spinning solution.  Filaments may be drawn in heated air or steam, and may subsequently be heat-shrunk.  Specification 902,581 is referred to.

Abstract: 824,864. Semi-conductor devices. TEXAS INSTRUMENTS Inc. Nov. 20, 1956, No. 35492/56. Class 37. In a graded junction rectifier or transistor comprising a block of semi-conductor material of one conductivity type, a material characteristic of the opposite conductivity type is alloyed and diffused into the surface by heating at a temperature in the range of 1000‹ to 1400‹ C. for a period of from 10 to 50 hours. An NPN junction transistor is described in which a silicon or block 10, Fig. 5, containing arsenic, bismuth, antimony or phosphorus, has an aluminium layer deposited in a crater 11 by vacuum plating or sputtering. The heat treatment which diffuses the aluminium into the block to form the graded junction is then carried out in an inert atmosphere of helium, argon or hydrogen. Subsequently, the layer is roughened and nickel-plated for attachment of a collector lead 15 by soldering. An emitter junction 20 is formed by alloying suitable material 19 into the opposite surface of the block, and an aluminium lead 18 is attached by alloying its end to the material by heating in a helium atmosphere. The same attachment method is used for the base connection (not shown). The use of gallium, indium, thallium or boron in place of aluminium is mentioned. The graded collector junction may alternatively be formed in a transistor of the PNP type. A field-effected transistor is shown in Fig. 6 in which an N-type silicon semi-conductor block 20 is encircled by a vacuum-plated or spluttered aluminium band 21. The graded junction is then formed as previously described, the diffusion of the aluminium atoms reducing the uncontaminated cross-sectional area of the block.
