Abstract: 712,168. Lubricating. UNION SPECIAL MACHINE CO. April 17, 1952 [April 18, 1951], No. 32664/53. Divided out of 712,147 [Group VII]. Class 12(3) [Also in GroupVII] In a sewing-machine having an oil reservoir or compartment with a duct leading from it through which oil flows to various parts of the machine, the duct has an orifice which is normally closed when the machine is idle by a valve element, such as a ball. which is displaced by vibration of the machine when in operation to allow free flow of oil through the orifice, so that the flow is automatically stopped when the machine is not in motion. The invention is described in application to a machine of the kind described in Specification, 712,147 arranged for closing the mouths of filled sacks, with the " base " and arm vertical and the " standard " horizontal. The reservoir 53 is attached at the upper end of the base, and is connected by a passage 57 with a manifold 58 from which pipes 53a lead to various parts of the machine. The passage is normally closed by a ball 55 in a cage 56 fixed over the passage, but when the machine is in action its vibration causes displacement of the ball to allow oil to flow through the passage. If only one pipe 53a is to be supplied, it is connected directly to the passage 57. One of the pipes communicates with a wick-filled bore opening into a bearing for the main shaft (which runs vertically in the base); the shaft is hollow and contains wicking to distribute oil from a radial bore within this bearing to other bearings and eccentrics. A helical groove in the lower end of the bearing opposes the downward flow of oil along the bearing.

Abstract: 326,762. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Nov. 16, 1928. Tetrahydronaphthols and their esters and ethers; hydrogenated organic compounds, catalytic production of.-ar-Tetrahydronaphthol esters are prepared by the catalytic hydrogenation of naphthol esters of the formula C10X7.O acyl, in which X represents hydrogen or one X indicates a monovalent substituent in the same ring as the ester group. Similarly, ar-tetrahydronaphthol ethers are obtained by the catalytic hydrogenation of naphthol ethers of the formula C10H2-n (O alkyl)n, in which n = 1 or 2; when n = 2, both ether groups are present in the same ring. The hydrogenation is effected in the presence of a base metal catalyst, and advantageously in an organic solvent such as tetra- or deca-hydronaphthalene. Saponification of the ar-tetrahydronaphthol esters yields the corresponding ar-tetrahydronaphthol. The products are useful as perfumes, intermediates for the production of dyestuffs, and pharmaceutical materials. Examples are given of the production of (1) ar-1-hydroxytetrahydronaphthalene acetate or benzoate from a-naphthol acetate or benzoate; ar-1-hydroxytetrahydronaphthalene is obtained by saponification of the product; in the same way, ar-2-hydroxytetrahydronaphthalene and its acetic acid ester are prepared from #- naphthol acetate; (2) the acetate of ar-2-hydroxytetrahydronaphthalene-3-carboxylic acid methyl or ethyl ester from the acetate of 2-hydroxy-3- naphthoic acid methyl or ethyl ester; the product yields ar - 2 - hydroxytetrahydronaphthalene-3-carboxylic acid on saponification; (3) the carbonic acid esters of ar-1-hydroxytetrahydronaphthalene from the corresponding ester of a-naphthol; it gives on saponification 1 - hydroxytetrahydronaphthalene; (4) the carbonic acid ester of ar-2- hydroxytetrahydronaphthalene from the corresponding ester of #-naphthol; (5) ar-1-methyl-2- hydroxytetrahydronaphthalene acetate from 1- methyl-2-hydroxynaphthalene acetate; (6) ar-1- methoxy or ethoxy-tetrahydronaphthalene from anaphthol methyl or ethyl ether; (7) ar-2-methoxytetrahydronaphthalene from #-naphthol methyl ether; from the ethyl, n-propyl, isopropyl and isobutyl ethers of #-naphthol the corresponding tetrahydro compounds result; (8) ar-1 : 4-dimethoxytetrahydronaphthalene from 1 : 4-dihydroxynaphthalene dimethyl ether. The hydrogenation is effected in the foregoing examples at a temperature of 50-110‹ C., under a hydrogen pressure of 20-80 atmospheres, and using nickel or a mixture of nickel with 15 per cent cerium as catalyst.

Title: Means for effecting asymmetrical phase displacement, in polyphase supply systems
IPC: H01F29/14
Filed: 1955-11-18
Abstract: 812,157. Phase displacement. BROOKE, W., and HOWE, H. Nov. 18, 1955, No. 33103/55. Class 38 (2). [Also in Groups XXXVII and XXXIX] An arrangement for reversing two of the phases of a three-phase supply to a polyphase induction motor comprises a number of saturable cores for each phase, each bearing primary and secondary windings and auxiliary saturating flux transferring windings, the interconnections of the main windings being such that the required result is obtained by suitable control of the flux transferring windings to saturate and desaturate the cores. In one arrangement, Fig. 1, two sets of four cores A, A1 ; D, D1 ; B, B1 ; E, E1 carry primary windings PA, PA1; PD, PD1 and PB, PB1; PE, PE1, connected in series between supply lines L1, L2 respectively and star point N, and two cores C, C1 with primary windings PC, PC1 between line L3 and point N. Each core carries a secondary winding SA, SA1; SB, SB1; SC, SC1; SD, SD1; SE, SE1, and these are arranged in voltage-opposing pairs, cross-connected between phases as shown in Fig. 1 and more clearly in Fig. 2 and connected to star point N1. The coupling effect can be transferred between members of each pair of cores such as A, A1 by energizing one or other of the flux transferring windings such as HA, HA1 on the core pairs. Fig. 3 shows a suitable circuit for rearranging the connection of the flux transferring windings by a switch J or alternatively by a potentiometer K4 and switch combined. With the switch in the " forward " position all cores except C, D, E are saturated so that secondary windings SA, SB, SC supply voltages from phases L1, L2, L3 respectively to terminals R, T, V. With the switch in the " reverse " position all cores but A, B, C are saturated and secondary windings SA, SB, SC supply voltages from phases L1, L2, L3 to terminals T, R, V respectively so that the phases connected to terminals R and T have been reversed. When moved between " forward and " reverse the switch passes through " off " in which position all the flux transferring windings are energized in series with an impedance of equal value, e.g. ZA, ZA1, so that equal and opposite voltages are developed in the secondary windings of the core pairs and the overall output voltages at terminals R, T, V are zero. Use of potentiometer K4 instead of switch J gives control of the output voltage. In one modification there are three cores for each input phase, Fig. 5 (not shown), the secondary windings being connected as shown in Fig. 6. In another modification there are two cores per phase, Fig. 12 (not shown), the secondary windings being connected as shown in Fig. 13. Suitable control circuits for the flux transferring windings of both these modifications are described (Figs. 8, 14, 15, not shown). Specifications 724,487, [Group XL (c)], 724,494, [Group XV], and 801,509 are referred to.
