Filed: 1964-02-17
Abstract: 995,991. Slicing machines. A. PAUL. Feb. 17, 1964 [Feb. 20, 1963], No. 6559/64. Heading A4C. In a machine for slicing bread, sausage, cheese &c. the slicing disc 15 (Fig. 1), mounted in or on a housing 10 and having a peripheral cutting edge, is drivingly interconnected with an electric motor 20 mounted in the housing 10 by a flexible shaft 21. The shaft 21 carries a worm 22 mounted in bearings to drive a worm wheel 16 splined to the hub 17 of the cutter 15. A chamber 19 beneath the cutter 15 receives, through a shoot 44, slices cut from a loaf &c. supported on a worktable 24, the latter being vertically adjustable to vary the slice thickness S. A pair of sliders 25 having handles 33 are housed in the hollow side walls 13 of the machine housing and are interconnected by a stirrup 30, 31 for simultaneous movement, whereby movement of the sliders 25 in the direction y causes lugs 27 on the worktable 24 to ride up inclined slots 26 in the sliders 25 at the same time being guided in vertical slots 23 in the housing walls 13 to effect vertical adjustment of the worktable 24. Means are provided to lock the worktable 24 in its adjusted position and the arrangement is such that by means of a lug 46 the motor 20 is rendered inoperative when the slice thickness S is set to zero. A shredding attachment (Fig. 5) comprises a lower housing 48 releasably attached to the sliciing machine above the slicing disc 15 and an upper housing 49 carrying a hopper 50 beneath the outlet of which is mounted a rotary shredder 56 driven through a shaft 55 splined to the hub 17 of the cutter 15.

Title: Improvements in the manufacture and production of sulphur
IPC: C01B17/033
Filed: 1934-03-05
Abstract: 430,110. Sulphur. JOHNSON, J. Y., 47, Lincoln's Inn Fields, London.-(I. G. Farbenindustrie Akt.-Ges.; Frankfort-on-Main, Germany) March 5, 1934, No. 6945. [Class 90] Sulphur is obtained from sulphur contaminated with tarry matter or masses containing it such as spent gas purifying masses by treatment with methylene chloride, ethylene chloride or chloroform to dissolve the tarry constituents and leave the sulphur substantially undissolved. The treatment may be carried out under pressure and at ordinary or slightly elevated temperatures, and the recovered tar may be used for making briquettes from coal waste, making road asphalts or illuminating gas. The sulphur may be further purified if desired by solution in ammonium sulphide or carbon disulphide or by fusion or distillation, after treatment with sulphuric acid, bleaching earths or similar agents if desired. According to examples : (1) carbon disulphide is passed through six containers in series charged with exhausted gas purifying mass. When the mass in the first container is exhausted of sulphur &c. the fresh solvent supply is transferred to the second container. The first container is treated with steam to recover the solvent, filled with fresh material and attached to the end of the series so that it comes into contact with solvent enriched in sulphur. This operation is then repeated as the containers are exhausted. The carbon disulphide is then lead through a column apparatus, the heating being regulated so that the effluent solution is just saturated with sulphur. This solution is cooled, and the crystalline sulphur filtered off. This crude sulphur is then freed from tarry matter by washing with ethylene chloride, and may be further purified by distillation. Alternatively, the gas purifying mass may first be extracted with the specified solvents to remove tars and then treated with solvents, or heated with steam to remove the sulphur. The Provisional Specification states also that ethyl ether, benzine, benzene, toluene and trichlorethylene may be used for the removal of tarry matter.

Title: Improvements in and relating to electrical transformers and the operation thereof
Inventor: NEWMAN REGINALD JAMES
IPC: H01F29/14
Filed: 1963-02-25
Abstract: 1,004,594. Transformers. JOHNSON, MATTHEY & CO. Ltd. Jan. 10, 1964 [Feb. 25, 1963], No. 7434/63. Heading H1T. Auxiliary windings 7 (Fig. 1) of an electric transformer A which comprises primary and secondary windings 3, 5 mounted on the central limb of a magnetic core 1, are provided on outer limbs 2 of the core and are connected in series opposition and in such a way across a switch 4 that, on restoring direct A.C. supply to the primary by closing switch 4, sufficient flux change occurs in the central limb, due to the arrangement of the auxiliary windings, to produce a back e.m.f. which reduces the surge current in the primary when the direct supply is interrupted at 4, A.C. will be supplied to the auxiliary windings in series with the primary. Since the auxiliary windings are wound in opposition to produce equal and opposite magnetic effects in the central limb, magnetization of the central limb only occurs due to the reduced current flowing in the primary. At the instant when the switch 4 is closed to shortcircuit the auxiliary windings the increased flow of current in the primary will increase the magnetization in the central limb and this magnetization will bo in the same direction as that provided by one of the auxiliary windings and in the opposite direction to that provided by the other auxiliary winding. A substantial flux change in one half of the central limb is therefore obtained and thus a back e.m.f. which will reduce surge current in the primary will be produced. The central limb may be divided into two portions 1a, 1b (Fig. 2, not shown) on both of which the primary and secondary windings are mounted. The arrangement may be applied to multi-phase transformers.
