Filed: 1972-03-17
Abstract: 1342556 Control of AC motors HITACHI Ltd 17 March 1972 [19 March 1971] 12666/72 Heading H2J Apparatus for controlling a three phase induction motor comprises a first relay having contacts 101 in each line and second and third relays having contacts 111, 121 in two of the lines only for interchanging their connections to the motor, and a variable impedance in the third line. The apparatus is used for smoothly braking the motor, which may drive a lift, by gradually increasing the impedance (which may comprise thyristors as shown or a saturable reactor) until the current in that phase is substantially zero, operating the interchanging relays 111, 121 and then gradually lowering the impedance to fully re-energize the motor in the reverse direction until it stops. The sequence is made automatic by controlling the variable impedance by the difference between an automatically varied reference voltage 1 on a capacitor C, (Fig. 3a not shown) and a tachogenerator voltage, and by detecting current zero in the controlled line by transformer CT. The tachogenerator TG also operates a deenergizing relay 17 when the motor has stopped. The motor is started with the impedance at maximum, and this is gradually reduced to give a smooth start. The relay circuits and their operation are fully described.

Abstract: 280,493. Chemische Fabrik vorm. Sandoz. Nov. 13, 1926, [Convention date]. Yarns, threads, &c., treating with liquids; fibres, treating.-The dyeing properties of vegetable textile fibres are modified by treatment in a bath consisting of a mixture of acetic anhydride, acetic acid, and a catalyst such as is used for the preparation of cellulose triacetate, the reactivity of the bath being substantially moderated and the reaction being allowed to proceed only as far as the production of cellulose mono- or di-acetate. The materials may be treated either in the loose state, or as yarns or fabrics; and the treated materials have no affinity for substantive dyestuffs, and may therefore be used in effect threads. The catalysts used are sulphuric acid and other mineral acids, sulphoacetic acid, halogen fatty acid, aromatic sulphonic and sulphinic acids. acid chlorides, acid salts, salts of strong acids with weak bases and also neutral salts, other than the heavy metal salts of organic acids except zinc acetate under the conditions specified below. In examples, one part of loose cotton is treated with 3 parts of acetic anhydride, 5 parts of acetic acid, and 0.0025 parts of sulphuric acid at 15‹ C. for two days, after which time the material is removed, squeezed, and washed; one part of cotton yarn is treated for 20 hours with a mixture of 4 parts of acetic anhydride, 4 parts of acetic acid, and 0.8 parts of zinc chloride, and afterwards centrifuged and washed.

Abstract: 463,678. Tempering glass. PERRY, H., and GROTEFELD, A. W. Sept. 30, 1935, Nos. 12858/36 and 12859/36. Divided out of 449,602. [Class 56] Relates to tempering-apparatus of the kind in which a glass sheet, or other glass article, is suspended from a carriage which runs along an overhead rail, and the sheet is conveyed from the furnace to the cooling-device by moving the carriage along the rail. According to the present invention a second rail is provided to enable the carriage, after the tempered sheet has been removed, to be returned to its initial position without interfering with the continuous movement of the sheets in one direction through the heating and cooling devices. The two rails may be parallel with one another and may be joined at their ends by curved rails to form a continuous track. In another construction, the rail 15 that extends through the furnace 10 and the cooler 11, and the return rail 18 have their ends adjacent to transferring-devices. These consist of transfer rails 19, 20 which extend - parallel with the main rails and are movable along pairs of rails 21 arranged at right angles to the main rails. Thus after unloading, a supporting carriage 27 is run on to the rail 20 and is transferred to the return rail 18, where it can be moved along and transferred by the rail 19 to the rear of the furnace 10 ready to convey another sheet through the apparatus. Instead of using a single furnace, a preheating and a main heating furnace may be used, and the preheating furnace may be heated by gas or other fuel. The cooling-device may be constructed as described in Specification 449,602 or 449,864.

Title: Electrically insulating sheathing of metals and metallic parts and products obtainedthereby
IPC: H01B3/40
Filed: 1958-04-23
Abstract: Metals are sheathed with thin, continuous, electrically insulating layers by moulding with an epoxy resin moulding composition which hardens when heated.  The moulding composition contains an aromatic polyamine as hardener, the formaldehyde condensates of aniline or m-toluidine, containing more than 50% of their nitrogen content in the form of primary amino groups, and also diaminodiaryl alkanes, e.g. 4 : 41-diaminodiphenyl ethane, 4 : 41 - diamino - 3 : 31 - dimethyldiphenyl methane, 4 : 41 - diaminodiphenyldimethyl methane, and 4 : 41-diaminodiphenyl methane being particularly suitable. Fillers, e.g. ground rock, wood flour, cellulose, asbestos fibres, glass fibres, mica, kaolin, quartz, metallic oxides or metallic powders, are added, either immediately after solution of the hardener in the epoxy resin or by grinding in a ball mill with the ripened and solidified solution.  In the example quoted, 103 parts of p : p1-diaminodiphenyl methane are dissolved in 400 parts of an epoxy resin which is liquid at room temperature and has been prepared from 4 : 41-dihydroxydiphenyl-dimethyl methane and epichlorhydrin, the solvation taking place at 60-62 DEG  C. in the course of 1 hour.  The solution, at 50 DEG  C., is poured on to a flat plate and kept for 4 hours in an oven at 50 DEG  C., after which it is cooled to room temperature and the resultant brittle resin ground in a cross-heater mill.  For the production of the moulding composition, 350 parts of the resin thus ground are further ground together with 650 parts talc, 15 parts glycerol monostearate, and 20 parts nigrosin for 32 hours in a ball mill and the resultant composition is compressed into annular tablets.

In lubricating compositions for internal combustion engines compounded with a metalcontaining organic addition agent for promoting engine cleanliness, avoidance of ring sticking &c., the metal corrosiveness of the compositions is greatly reduced by the use of a mineral lubricating oil comprising a refined base stock capable of imparting a blue to black stain on a bright steel strip which has been immersed in the oil base stock in the absence of addition agents for 2 hours while the oil temperature is maintained at 425 F. Preferably, the base oil stock is one which gives no stain with the standard A.S.T.M. copper strip corrosion test when conducted for ¢ hour at a temperature of 212 F. Suitable stocks specified comprise extracted and acid refined Panhandle paraffinic crudes. The addition agents may be metal salts of hydroxy organic compounds, e.g. metal phenolates, alcoholates, aroxy sulphides, and enolates ; and also the metal salts of organic acids, e.g. metal soaps, metal salts of organo substituted phosphoric and salicylic acids, xanthates and sulphonates. Compounds specified comprise barium di-isobutyl phenoxy sulphide, cobalt p-ter. amyl phenoxy sulphide and nickel oleate. Corrosion inhibitors may also be added such as higher alcohols, amines, esters, ketones and ethers ; a suitable compound specified comprises stearyl alcohol. The preferred proportions of the metal compounds range from 0.05 to 1.5 per cent, particularly 0.2 to 1.0 per cent.

Aerials.-A lead-in device for connecting an aerial to a receiving apparatus is associated with a lightning arrester or spark gap, the latter being formed between the conducting rod of the leadin and an annular earth-connected member carried at the outer end of the insulating tube. The conducting rod c is secured at one end to the aerial wire n and at the other end to a wire leading to the receiving-set. The rod is held in spaced relation within the insulating-tube a by means of a flanged nut d.
