IPC: C21C5/28
Filed: 1952-11-24
Abstract: 728,007. Refining steel. WARNANT, R. E. Nov. 24, 1952 [Nov. 23, 1951; Oct. 29, 1952], No. 29664/52. Class 72. A process for converting pig iron into steel low in nitrogen comprises blowing the steel with a mixture of oxygen and superheated steam in which the temperature of the blowing mixture is controlled by adding to at least one of the constituents of the mixture the hot products of combustion of a fuel burnt under pressure to maintain the superheat of the steam in the mixture at the required degree. As shown, steam is introduced through a pipe 2 into a heating chamber 5 into which are also led the products of combustion of a fuel, e.g. methane, coke oven gas, lighting gas or water gas or mixtures of these gases, burned in an antechamber 7. Oxygen from a pipe 13 is mixed with the mixture coming from the heating chamber 5 and the mixture of oxygen, superheated steam and products of combustion is supplied to a converter 4 through a pipe 17 having a blowing valve 18. A proportional regulator 21 controlled by a thermo regulator 23 actuates flow meters 19 and 20 controlling steam and fuel from a pipe 8 respectively entering the heating chamber 5, the oxygen for combustion of the fuel being controlled by a flow meter 26. A thermo regulator 32 on the outlet side of the chamber 5 operates a motorized valve 31 leading to an escape valve 29 in such manner that the valve 31 shuts as the temperature of the mixture exceeds, and opens as the temperature is lower than, the degree of superheat required. In a modification, Fig. 2 (not shown), oxygen may be added to the mixture in the heating chamber 5 and in a further modification the burner may be supplied with air which may be enriched with oxygen and the escape valve 29 may be under manual control, Fig. 4 (not shown).

Title: Method and Apparatus for Axially Developing Electrical Coils
IPC: H02K15/06
Filed: 1968-06-24
Abstract: 1,189,258. Making dynamo-electric machines. GENERAL ELECTRIC CO. 24 June, 1968 [1 Aug., 1967], No. 30050/68. Heading B3A. A method of inserting an electrical coil in a slotted magnetic core comprises, forming at least one coil, transferring the coil to a location adjacent selected slots of the core by tools having curved wall sections in engagement with some of the turns and adapted to enter into the selected slots, and axially inserting side turn portions of the coil into the slots with the curved wall sections entering the slots at a pre-determined core end-face. The required number of coils are wound at a first position A on a collapsible, stepped, cantilever coil form 24 in co-operation with a flyer 26, and then transferred to a position B. The coil form includes an elongated member 32 having a key 33 which fits into a slot entrance of a stator core 14. The transferring and inserting device is provided with elongated tools which comprise curved divider members 42, 43, which serve as part of the winding form, and pusher elements 46, 47, 48. Each element includes a channel for accommodating the end turn portions 51 of the coils and a blade extension 53 provided with a polished, curved and tapered leading section (54), (56), Figs. 4, 5 (not shown). During transfer the dividers 42, 43 move axially over coils 21, 22 and the pusher elements 46, 47, 48 engage the turns driving them towards position B. When the coil 21 is adjacent the core 14, coils 22, 23 are sequentially radially aligned with coil 21. Further movement of the tool forces the coils into the slots with the blade extensions 53 also entering into the slots, the free ends of the dividers 42, 43 stopping in alignment with the further end face of the core and the elements 46, 47, 48 passing axially therethrough. The tools are then retracted from the core and returned to position A. The length of the extensions 53 is preferably great enough to allow them to protrude rearwardly beyond the end turns when the tools are in their extended positions. An air cylinder assembly 87 moves a rack 75, Fig. 2, in the direction of the arrow in Fig. 10, thereby allowing a spring 89 to move an assembly 60 away from a threaded stop 85, with which it is normally in contact, until it abuts the opposite side of a base 61. This movement disengages the key 33 from the stator slot in which it was located. Further movement of the rack drives an index gear 77 and angular motion is transmitted to the core 14 via a pawl 81 on the gear 77 which is biased into a notch 82 in a cam ring 78. The number of notches 82 provided depends on the required index angle for the core 14, which is coupled to the cam ring by a pin 84. The core is held axially by arms 71, 72 and sufficient clearance is provided to allow it to rotate on a mandrel 64. When the rack performs its return stroke, the pawl 81 is biased out of the notch 82, and when it abuts a lug 88, the assembly 60 is moved until it contacts the stop 85. This movement of the assembly engages the key 33 in a further core slot.

Abstract: 833,381. Luminescent materials and processing. SYLVANIA ELECTRIC PRODUCTS Inc. Sept. 25, 1957 [Oct. 24, 1956], No. 30142/57. Class 39(1). The use of titanium or tungsten activators in magnesium lithium antimonate phosphors instead of manganese or uranium activators described in Specification 707,101 has been found to shift the emission from the red to green region of the spectrum towards the blue region. In addition, the use of titanium as a secondary activator with manganese or uranium as the other activator raises the light emission above that of phosphors in which Mn or U alone are used. It is preferred to use basic magnesium carbonate, lithium carbonate and antimony trioxide as raw materials, the titanium or tungsten being added in the form of TiO 2  or WO 3 H 2 O. The preferred concentrations of the various materials and tables showing the effect of activator concentrations and firing temperatures on emission are given together with two specified examples of phosphors. The dry constituents are mixed, fired at a temperature of about 1800‹F. to 2000‹F., cooled, ground, and then refired at a higher temperature.

Abstract: 516,164. Alkyl phenols. TENNANT, W. J., (Dow Chemical Co.). Oct. 21, 1938, No. 30546. [Class 2 (iii)] Tertiary alkylphenols are prepared by reacting a phenol with a tertiary monohydric saturated aliphatic alcohol containing,less than 6 atoms per molecule, in the presence of a small proportion of stable dehydration and condensation catalyst, while vapourizing - water from the reaction' mixture and without the presence of an additional volatile liquid having a boiling point lower than the appropriate operating temperature. The essential reactions are :- alcohol # olefine + water olefine + phenol # alkyl phenol. Alcohols specified as starting materials include tertiary butanol, and tertiary amyl alcohol. The phenols used may be either monohydric or polyhydric. Specified phenols include phenol, o-chlor phenol, cresols, chloro cresols, naphthols, phenyl phenols, resorcinol, guaiacol. The catalyst used must be stable, that is, not decomposed by the water of the reaction. Catalysts specified include the bleaching earths sold under the trade names " Retrol " or " Tonsil," as well - as sulphuric acid, ferric chloride, zinc chloride and sulphonic acids. The alkylation is carried out by heating the phenol and catalyst to the desired reaction temperature which will vary somewhat with the particular materials employed, and then slowly adding the alcohol with stirring. The preferred temperatures are between 135‹-180‹C. The product of the invention is usually the para isomer, provided the position is free. In examples (1) a mixture of Retrol and phenol is heated to 150‹C. at atmospheric pressure and tertiary butanol added with vigorous stirring during two hours. This is followed by a one-hour heating at 170‹C. to give ditertiary butyl phenol. (2) Tertiary butanol is added under the-conditions of example (1) to a mixture of sulphuric acid and phenol to give tertiary butyl phenol. (3) Tertiary amyl alcohol is added under the above conditions to a mixture of phenol and Tonsil. (4) Tertiary butanol is added as above to a mixture of orthocresol and Retrol to give para-tertiary butyl ortho cresol. (5) Tertiary butanol is added as above to a mixture of ortho-chlor phenol and Tonsil to give para tertiary butyl ortho chlor phenol. Specification 424,506 is referred to.
