Title: Improvements in or relating to methods of and apparatus for making wrought iron
IPC: C21C3/00
Filed: 1937-09-29
Abstract: 503,194. Manufacture of wrought iron. STEVENS, A. H. (Byers Co., A. M.) Sept. 29, 1937, No. 26365. [Class 72] A method of making wrought iron comprises using a batch of molten slag for incorporation of portions thereof with ferrous metal to form a ball of wrought iron, separating said ball of wrought iron from the slag in said batch not incorporated in said ball, and from time to time incorporating additional molten slag into said batch of slag for reuse in the formation of further balls. The apparatus employed is substantially similar to that shown in Specification 344,277: Metal from the cupolas 2 is transported to the Bessemer converters 8 along the rails 10 and the Bessemerized ferrous metal is conveyed in ladles on the rails 27 and then transferred by means of an overhead crane to shotting machines 21. A shotting machine, Fig. 8, comprises a ladle 32 mounted for tilting on trunnions 50 supported on a table 31 capable of rotation on the track 41. This track 41 is on a platform 30 capable of reciprocal motion along the rails 34. The whole is carried on the beam of a weighing machine fitted with an indicating dial. In operation, slag from the furnaces 13, Fig. 1, is poured into the slag receptacles 24 and the receptacles are run on the track 25 so as to lie beneath the shotting machines 21. Meanwhile a batch of ferrous metal from the converters has been transferred in part at least to one or more of the shotting machines, the amount poured into each machine and determining the size of the ball being shown on the indicating dial. The ladles 32 are then caused to oscillate and to reciprocate, so that on tilting the stream of ferrous metal traces paths of varying shape. The train of receptacles 24 now containing wrought iron and excess slag is moved to a slag transfer station opposite the press 22. Preferably the train comprises an extra empty receptacle. The excess slag from one filled receptacle is decanted into the empty receptacle, its iron ball being dumped into the press, and the slag from a second filled receptacle is decanted into the first &c., so that the last receptacle is empty and ready for the next operation, and may be retained at the slag transfer station therefor. If desired the train may contain twice as many receptacle cars as the number of shotting machines used. The train is now run opposite the slag furnaces 13 and additional molten slag is added to each receptacle. Alternatively the additional slag may be added at the slag transfer station, and this may be before the iron ball is dumped. This incorporation may take place every second or third cycle. Specification 315,826, [Class 72], is referred to.

Title: Hydrogenation of unsaturated aldehydes and ketones
Filed: 1959-07-31
Abstract: The olefinic bond of an a ,b -unsaturated aldehyde or ketone is selectively hydrogenated by treating the unsaturated compound with hydrogen in the presence of a catalyst comprising rhodium and/or ruthenium, and terminating the reaction when the olefinic bond is saturated.  The product is the corresponding saturated aldehyde or ketone.  Examples of the aldehydes and ketones which may be used as starting materials are mesityl oxide, crotonaldehyde, acrolein, vinylmethylketone, phorone, cinnamic aldehyde, benzalacetophenone and 2,4-hexadiene-1-al.  The reaction temperature may be in the range from - 10 DEG C. to 300 DEG C. and if desired a solvent may be present.  The catalyst may be supported on a conventional support and may be in the form of powder, pellets or granules.  Reference has been directed by the Comptroller to Specification 816,151.

Title: Improvements in methods and apparatus for producing bulked yarn
Inventor: SCRAGG FREDERICK

Abstract: 858,438. Finishing yarns. SCRAGG & SONS Ltd., E. Aug. 5, 1959 [Aug. 16, 1958], No. 26415/58. Class 120(3). [Also in Group XI] Multifilamentary thermoplastic yarn is bulked by continuously withdrawing the yarn from a package, optionally with application of real twist, (2-4 turns per inch) passing it through a heating i.e. setting, zone and drawing it through a false-twisting device by feed rollers rotated at a predetermined peripheral speed, winding the yarn on to another package at a peripheral speed less than that of the rollers, and subjecting it to a further heat treatment (as a package or during its approach thereto) the duration and temperature of which is so adjusted as to remove at least some of the internal stresses in the yarn and during which the yarn may be allowed to contract a predetermined amount and set. As shown, Fig. 3, yarn is drawn from a package 12 through a " balloon stabilizer " or tensioner 14 by nip rollers 13, 15, and pulled over the surface of a heater 16 and through a falsetwist tube 17 by nip rollers 18, 19, the peripheral speed of which may be less than that of rollers 13, 15: crimped yarn is permitted a limited contraction as it is wound on a package by roller 1 driven at constant peripheral speed. The package 8, Fig. 1, is supported on arms, as at 2, pivoted on a shaft 7 carried by a support 10. As the size of the package 8 increases, a bell-crank lever 9 resting on one arm 2 pivots arms, as at 3, on shaft 7 so that the position of an electrically heated oven 6 (see Group XI) is adjusted to maintain constant spacing between heaters 4 and the package surface. The temperature(s) of heater 16 and/or oven 6 may be automatically controlled.

Abstract: 861,970. Fluid-pressure servomotor-control systems. DOYLE, O. K. Aug. 24, 1957, No. 26768/57. Class 135. In a liquid-level float-controlled valve, Fig. 3, the pressure in a chamber 53, having a flexible wall 42 which is seatable on the end of an inlet pipe 10, is controlled by a rod 60 having a flattened portion co-operating with an opening 55 in the upper side of the chamber, so that when the rod 60 is lowered, Fig. 2, not shown, the chamber communicates with exhaust and an opening 46 in the wall 42 leading to the inlet pipe is closed by the lower end of the rod 60 and inlet pressure acting on the lower side of the wall 42 flexes it upwards to open the valve. On raising the rod 60, Fig. 3, the opening to exhaust is closed and that to the inlet pipe 10 opened and inlet pressure acting over a larger area of the wall 42 in the chamber 53 than on on the outside closes the valve. Fig. 1 shows the valve contained in a casing 14 attached to the top of the standpipe 10 mounted in the bottom of a tank and actuated by an openended annular float 20 surrounding the standpipe and mounted on a float arm 17 which engages a loop 77 on the upper end of the rod GO and is pivoted at 76 in a shell 66 which forms the top of the valve casing and by means of a slot 80 acts as a guide for the loop 77 to constrain the rod 60 to move vertically. The outlet from the casing is by means of four depressions 33 which form cylindrical passages, 29 only shown, at the lower end of the casing that are so dimensioned as to induce streamline flow and permit silent operation of the device. In Figs. 6, 7, not shown, the lower end of the rod is formed as a hemisphere and the slot 80 is widened to permit angular movement of the rod to open the bore 55.

Abstract: 1,160,133. Transformer ratio arm bridges. WAYNE KERR CO. Ltd., R. CALVERT and J. MILDWATER. June 12, 1967 [June 17, 1966], No.27259/66. Heading G1U. In a transformer ratio arm bridge for measuring impedance, the voltage drops across the transformer leakage impedance and in the leads to an unknown impedance 10 are compensated by feeding to an amplifier 30 the difference between the actual and desired voltage across the unknown impedance, and supplying the amplifier output as a correcting voltage in series with the unknown impedance, as shown, or as a compensating voltage applied to the standard impedance 11. The currents through the unknown and standard impedances are compared in an output current transformer 20 feeding a null-balance detector 22, and adjustment of the bridge for balance is effected by varying the supply to the standard impedance. This is done by connecting the standard impedance to a variable position tap either on the winding 16 itself, or on a rheostat connected across the winding 16 and the secondary winding 42, Fig. 5 (not shown) of a transformer on the output side of the amplifier. Alternatively, the bridge is balanced by connecting the standard impedance to a variable position tap on the primary of the output current transformer. The amplifier 30 is a high gain amplifier if the compensating voltage is applied to the unknown impedance and a unity gain amplifier if the voltage is applied to the standard impedance. In all cases the voltage it is desired to supply to the unknown impedance is taken from a winding 31 having the same number of turns as the winding 15 which actually feeds the unknown impedance.
