Title: Arrangements of the bus-bars of electrolytic furnaces
IPC: F27D11/00
Filed: 1954-02-05
Abstract: 740,025. Electrolytic furnaces; current supply. ELEKTROKEMISK AKTIESELSKAP. Feb. 5, 1954 [Feb. 5, 1953], No. 3417/54. Class 39(3). A battery of electrolytic furnaces 12 e.g. for producing aluminium is arranged in an even number of parallel rows supplied with D.C. by main bus bars 11 which for each pair of adjacent rows are grouped close together and extend between the rows of each pair ; and the current flows in one direction in one bus bar 11 to one row of furnaces in series and in the opposite direction through the other adjacent bus bar 11 to the other row of furnaces in series, so that electromagnetic fields due to the bus bars 11 are minimised. Auxiliary bus bars 13a, 13b connected between the main bus bars 11 and the anode and cathode of each furnace 12 are also grouped closely in pairs with the current flowing through them in opposite directions to minimise electromagnetic fields therefrom. The auxiliary bus bars of each furnace are arranged symmetrically about the horizontal transverse axis of each furnace. Thus in Fig. 4 four main bus bars 11 are ar. ranged close together between two rows of furnaces, with branch bus bars 13a, 13b connected respectively to symmetrical anode bus bars 14a and cathode bus bars 14b at each side of the furnace grouped close together and connected to two of the main bus bars 11 in series as shown. Conductors 15 connect the bus bars 13a to the anode bars 14a and lie close to cathode bars 14b leading current to the return bus bars 13b. In Fig. 6 branch bus bars 21a, 21b connected to symmetrically arranged anode bus bars 22a and cathode bus bars 22b are located in pairs adjacent the two ends of the furnace, and each bus bar 21a is close to a bus bar 21b in which the current flows in an opposite direction. The anode and cathode bus bars 22a, 22b extend symmetrically round the ends of the furnace.

Spray carburettors.- Rich mixture passes through a slidable tube 10 the upper end of which constitutes a secondary air valve with a valve-seat 14; the tube 10 also carries a plug 21 which constitutes a throttle valve with a valveseat 22. The end of the tube 10 should be fared as shown and the plug 21 and the valve-seat 14 should both be either conical or parabolical. Fuel is supplied from a nozzle 8, the delivery from which may be controlled by a needle valve, and the primary air supply may be adjusted by axial movement of a tube 9 which is preferably parabolic in section as shown. The tube 10 has a shoulder 17 on which rests a ferrule 18 to which is screwed the plug 21. The plug 21 is extended to form a conical baffle 20. Part of the sides of the plug 21 may be cut away so that the throttle may open more rapidly at first. The tube 10 is moved by a control lever having a slot which engages a pin attached to the tube. The valve-seat 22 is independently adjustable to admit a rich mixture at starting. The tube 9 may be connected to the control lever of the tube 10 with the interposition of a time lag so as to give a richer mixture automatically at starting and a weaker mixture at stopping. Compressed air may be used as the secondary air supply.

IPC: E04B2/56
Filed: 1947-02-07
Abstract: 635,617. Buildings constructed of prefabricated elements ; bricklayers' templets ; tie-rods ; ; wall ties. MARGRETT, S. D. Feb. 7, 1947, No. 3667. [Classes 20 (i), 20 (ii) and 20 (iv)]  Buildings are constructed using prefabricated framework elements by erecting on a foundation 1, Fig. 1, corner and intermediate stepped uprights 2, 3, 4 and stringing courses 12, the framework being braced by temporary adjustable stays 5, and erecting a cavity wall of concrete &c. blocks between adjacent uprights using an expansible transom 15 extending in the wall cavity and secured between the uprights by engagement with the stepped portions thereof. The uprights may comprise inner and outer portions 7, 7a, 8, 8a, 9, 9a as shown in Fig. 1 and additional uprights and stringer courses may be erected to form a second storey while a roof may be erected on the framework before the erection of the walls. The uprights are keyed to the foundation and stringer courses 12 by dowels la, 6b respectively. The inner and outer uprights are spaced by bolts 10 each having a pair of spaced slots 10a, Fig. 5, engaged by slotted washers I which coact with the inner faces of the uprights when nuts 10b are tightened. The transom 15, Fig. 3 comprises two parallel units each consisting of upper and lower horizontal angle members 15a, 15b, connected by a face plate 15c, the angle members of the two units overlapping and being connected by means of bolts extending through slots in the overlapping parts so as to permit a limited movement of the units towards and away from one another. This movement is effected by rods 18 and links 17. Rods 20, Fig. 1, secured at the ends of the transom engage the stepped edges of the uprights, and the face plates 15c are forced apart to engage the inner sides of the spaced uprights, so that the transom 15 fills the wall cavity and serves as a guide for erecting the wall blocks, it being raised in stages for successive courses by moving the face plates 15c towards each other, positioning the transom at a higher level and forcing the plates 15c apart again. The transom also serves to prevent cement or mortar from falling into the wall cavity. The adjustable stays 5 which remain in position until the filling of the walls is completed, comprise two members 5a, 5b, Fig. 6 connected together by bolts 5c, 5d with right and left hand threads and a correspondingly screwed sleeve 5e, the bolts 5c, 5d being fixed to the members 5a, 5b by bolts 5f engaging in one of a series of holes 5g for coarse adjustment. The frame units may be reinforced and the inner and outer uprights may be erected separately or as prefabricated combined units spaced apart by bolts &c.

Title: Improvements in or relating to the production of artificial yarns and similar articles
IPC: D01F2/30
Filed: 1941-03-20
Abstract: 557,004. Artificial yarns &c. ; cellulose derivatives. DREYFUS, H. March 20, 1941, Nos. 3813, 7868, 13197, and 14506. [Class 2 (ii)] Artificial yarns and the like made of an acetone-soluble cellulose acetate of a viscosity of at least 40 (measured by comparing the rate of flow of a 6 per cent. solution of the acetate in acetone with that of glycerine, which is taken as 100) are subjected to a stretching operation so as to obtain products of high dry and wet tenacity. The stretched materials may be subjected to saponification, which may be carried to completion. The cellulose acetate may be obtained by treating cellulose with acetic anhydride, acetic acid, and sulphuric acid in fairly high proportion, e.g., 10-15 per cent. of the weight of the cellulose, and maintaining a low temperature not exceeding about 30‹ C. Alternatively, a mild acetylation using a low proportion of sulphuric acid, or ferric, stannic, or zinc chloride, preferably with hydrochloric acid, may be effected at a temperature up to about 50‹ C. The acetylating medium may contain water-immiscible solvents such as methylene or ethylene dichloride, ethylidene chloride, or chloroform. The subsequent ripening is preferably carried out with fairly high proportions of added water, e.g. 40-50 per cent. of the cellulose when 10-15 per cent. of sulphuric acid has been used as catalyst, or up to 100 per cent. when 1 or 2 per cent. of sulphuric acid has been used. The acetyl content of the ripened cellulose acetate may be 50-53 per cent. calculated as acetic acid. The artificial yarns may be obtained by spinning a solution of the acetate in acetone, dioxane, methylene ethylene ether, or acetone and water or alcohol. High viscosity spinning solutions may be used. Hot solutions may be spun into a cool atmosphere. Stretching of the yarns may be effected with the aid of acetone, dioxane, wet steam, or hot water. Saponification may be effected by means of ethylene diamine, aniline, or caustic soda. Regenerated cellulose yarns of dry tenacity of 8-9 grams per denier and of wet tenacity 75-90 per cent. of the dry tenacity may be obtained. The yarns may be formed into cords or knitted, woven, or other fabrics, e.g. cords or fabrics for parachutes, sails and tents. Specifications 207,562, [Class 2 (ii)], and 443,707, are referred to. The Provisional Specifications describe also the stretching of filaments, yarns, films and foils of cellulose organic derivatives, including cellulose propionate, butyrate, and acetostearate. Specifications 438,584, 438,585, 438,586, 438,587, 438,655, 438,656, and 443,773 are referred to .
