Title: Static method of controlling the refining reactions of pig iron for steel making purposes in an oxygen top blowing converter
IPC: C21C5/30
Filed: 1975-01-13
Abstract: 1500188 Controlling oxygen steelmaking VEREINIGTE OSTERREICHISCHE EISEN-UND STAHLWERKE-ALPINE MONTAN A G 13 Jan 1975 [15 Jan 1974] 1333/75 Heading C7D A top-blown oxygen steelmaking process in which refining is carried through to completion is statically controlled to obtain desired final values of Mn and P in the steel by initially calculating the amount and type of lime to be used according to predetermined relationships. Refining is then carried out according to a pre-set blowing schedule with no further control action. The process is based on estimation of the proportion of charged lime which will be in solution in the slag by the end of refining (a parameter which may be varied by modification of the grain size or the amount of fluxing additions) and on the oxidizing capacity of the slag as measured by its iron oxide content. The relationships on which control is based are determined for a particular installation by analysis of the data from previous heats.

Abstract: 474,062. Loud-speakers. MONTLUCON, J. J.-B. F. Jan. 16, 1936, No. 1477. Void. Convention date, Jan. 17, 1935. [Class 40 (iv)] An electromagnetic driving unit for a loudspeaker comprises an armature in the form of a rocker of magnetic material arranged to roll on a rectangular magnetic circuit through which passes a permanent energizing flux which passes also through the rocker, means in conjunction with the magnetic circuit for superimposing on the permanent flux a modulated alternating flux which determines the rolling or oscillation of the rocker as a function of the displacement of the resultant flux due to the superimposition of the modulated flux on the permanent energizing flux. As indicated diagrammatically in Fig. 1, the magnetic circuit comprises limbs AB, BC, CD, DA two of which are surrounded by coils H, H<1> to which the speech currents are fed. The limb AB is formed with a number of notches E in which are located closed rings G, the effect of the notches and rings being to introduce a number of oppositely directed magnetic forces which, together with the magnetic force acting at the line of contact of the rocker K with the upper limb AB, produce a resultant force acting at a point to the right or left of the point of contact and cause oscillatory movement of the armature or rocker K as described in connection with Figs. 2, 3, 4 (not shown). In the arrangement shown in Figs. 5, 6 the armature 9 rolls on the upper limbs of two rectangular magnetic circuits formed by laminated polepieces 3, 3<1> attached by brackets 2 2<1> of magnetic metal to the arms of a U- shaped magnet 1. Each upper limb is formed with notches 10 in which are mounted turns 11 of copper, or other good-conducting metal, closed on themselves or attached to adjacent turns. In the arrangement according to Fig. 6, magnetic teeth inserted in recesses in the plates 7 of the laminated polepiece clamp the turns 11 between them. The speech currents are fed to coils 12 mounted on opposite arms of the rectangular polepieces or are applied to the primary winding of a transformer of which the secondary winding is connected to the plates 11. The armature 9, Figs. 7, 9 consists of two bundles of thin plates 13 separated by an intermediate member of hard material forced into a recess in each of two hard'steel plates 15. Each bundle of plates is divided into groups, the corresponding bundles of the groups being comiected by bundles 16 of plates, stated to be of different lengths and arranged to provide a stepped upper surface for the laminated structure. The armature is connected to a diaphragm by a rod 22 formed with a blade 21 clamped between a member 18, seated on the members 15, and a member 19 by means of nuts 20 on screw-threaded pins 17 fixed in the intermediate member. The two rectangular magnetic circuits may be designed to give maximum efficiency for high and low frequencies respectively.

Title: The manufacture of a new chloro-ethyl-ester and the treatment of phenols, alcohols and amino compounds therewith
IPC: C07C309/73
Filed: 1922-01-19
Abstract: p-Toluenesulphonic-b -chlorethyl ester is obtained by heating p-toluenesulphonic chloride with glycol chlorhydrin; it may be distilled in vacuo.  In an example an excess of the glycol chlorhydrin is used.  Ethylene-ethers and chlorethylethers are obtained by interaction of the above-mentioned p-toluene sulphonic chlorethyl ester and alcohols, phenol, cresols, p-nitro-o-cresol, naphthols, or aminophenols; in the latter case the amino groups are first protected; o- or p-nitro-phenols do not readily give ethers by this process.  The chlorethylethers obtained from the phenols &c. react with arylamines or monoalkylamines such as ethylaniline to give b -phenoxyethyl derivatives of the said bases; these derivatives yield nitroso compounds.  According to examples, the following compounds are prepared:- (1) phenyl-b -chlorethyl ether and some diphenylethylene ether from phenol and p-toluenesulphonic-b -chlorethyl ester, and a - or b -naphthyl-b -chlorethyl ether and a - or b -naphthylethylene ether from a - or b -naphthol; the b -naphthyl-b -chlorethyl ether, heated with dimethylamine under pressure, gives b -naphthyl-b -dimethylaminoethyl ether, of which the hydrochloride has a local anaesthetic action; the b -naphthyl-b -chlorethyl ether may also be nitrated, reduced and the amino compound boiled with amyl alcohol, potassium carbonate and copper powder, to give an a  : b -naphthylene morpholine: (2) benzyl-b -chlorethyl ether from benzyl alcohol; with diethylamine it yields b -diethylaminoethylbenzyl ether which forms an ammonium iodide with ethyl iodide: (3) o- and p-acetamino-b -chlorethyl ethers from o-acetaminophenol and acetyl - p - acetaminophenol, CH3.CO.NH.C6H4.O.CO.CH3, respectively.  Ethylenediamine derivatives, chlorethylamines, and piperazine derivatives are prepared by interaction of p-toluenesulphonic-b -chlorethyl ester and amines.  In examples the preparation of the following compounds is described:-(1) diphenylethylene diamine and diphenylpiperazine from aniline: (2) sym-dimethyldiphenylethylene diamine and b -chlorethylmethylaniline from methylaniline; the reaction mass is steam distilled when the diamine remains behind; the distillate, which contains the b -chlorethylmethylaniline is freed from methylaniline by treatment with p-toluenesulphonic chloride. b -Chlorethylmethylaniline condenses with b -naphthol in presence of alkali to form b -naphthyloxyethylmethylaniline.

Title: Improvements in hydraulic control for templet-copying devices on machine-tools
Inventor: FOUQUET SERGE
IPC: B23Q35/18
Filed: 1951-01-23
Abstract: 684,809. Copy-turning. COMPAGNIE GENERALE DE CONSTRUCTION DE LOCOMOTIVES (BATIGNOLLES-CHATILLON). Jan. 23, 1951, No. 1725/51. Class 83 (iii). A copying-lathe &c. having a tracer valve 6 controlled by a tracer 1 engaging a templet 2 and a tool-carriage 8 operated by a hydraulic piston 5 under the control of the tracer has an additional valve 13 fitted in the return fluid line from the hydraulic cylinder and controllable by the machine operator to throttle the return fluid and vary the rate of displacement of the tool carriage to and from the work. Pressure fluid is supplied under constant pressure to both sides of the piston but the leak through the spring-opened tracer valve 6 on the piston-rod decreases the pressure in the cylinder chamber 9a so that the tracer and tool are moved inwards until the tracer meets the templet. The tracer has tapered front and side surfaces and on a parallel portion of the templet is rotated about its axis 3 to restrict the valve opening sufficiently to balance the pressure on both sides of the piston. On meeting a slope on the templet, the tracer is further rotated and the further restriction of the valve-opening allows pressure to build up in the cylinder portion 9a, thus moving the tool and tracer outwards. The spring- opened plunger of the throttling valve 13 is operated by a hand lever 24 and eccentric 22 and two stops, such as 31, of different height, are adjustably placed at each end of the lever travel so that the valve can be set to give two rates of displacement of the tool carriage in either the inward or outward direction; the inner stops give a slow displacement and are of lower height so that they can be passed over by allowing the lever to move outwards about the pivot 27 under the action of a spring 25. On completion of the copying operation, the operator moves the lever down to restrict the opening of the valve 13 and so retract the tracer and tool. As the tool carriage retracts, a dog 40, Fig. 12, adjustable on the carriage, rides over a rotatable cam 37 but, when the operator increases the opening of the throttle valve by raising the lever and so moves the carriage inwards, the dog 40 rotates the cam and, through a lever 32, restricts the valve opening so that the pressure on both sides of the piston 5 is balanced, thus arresting the return movement of the tool at a predetermined position. To engage the work and tool again, a lever 45 is rotated so that a cam 44 withdraws the cam 37 from the path of the dog 40 and allows the valve 13 to open.
