[Also in Group XXX] In an earth-moving machine the longitudinal tubes 13, 15, Fig. 2, of the two sections 10, 11, of a telescopic jib which are guided by rollers 18 are attached to transverse members 12, 14 in such a way that the tubes may be rotated about their longitudinal axes after being detached from the transverse members in order to bring unworn portions of the tubes into contact with the rollers 18. As described, the jib is triangular in cross-section and the tubes 13, 14, Fig. 4, are attached by bolts 17 to arc-shaped portions 12a, 14a of the transverse members 12, 14. Four tapped holes are provided in the tubes at each attachment point so that four different portions of each tube may successively bear against the rollers 18.

Title: Improvements in smoke detecting apparatus
IPC: G01N21/53
Filed: 1930-10-01
Abstract: In a smoke detector apparatus in which a sample stream of the exhaust products is continuously drawn by pipes 19, 20 from the smoke stack through an observation tube 1 having at one end a projector lamp 2 and at the other end a light-sensitive cell, a recess 21 is provided opposite the <PICT:0364661/III/1> smoke stream entering the observation tube for the automatic deposit of entering soot.  The recess 21 extends downwardly from the tube 1 beneath the induction pipe 19 and has a removable lower closure, while a U-tube 22 containing liquid forms a draught gauge giving a measure of the rate of flow of the sample stream.  The induction and exhaust pipes 19, 20 are located some distance from the ends of the tube 1 to prevent soot being deposited on the lamp and cell or on glass panes closing the ends of the tube.  The selenium cell 3 (or photo-electric cell 3a) is connected in the grid circuit of a thermionic amplifier 4 the plate circuit of which controls a milliammeter 5 and, through a relay 6, a signal lamp or bell 7 which gives a warning when the opaqueness of the products exceeds a certain limit.  A transformer 23 feeds the lamp 2 and a concave mirror 24 is provided for focusing the rays along the tube.  In the direct-current circuit shown the filament of the valve 4 is connected to the mains through variable resistances R1, R2 and pilot lamps 9.  The selenium cell 3 is connected between the grid and a variable tapping point 15 of the resistance R2 and the grid is connected through resistance R3 with a tapping point 16 of the resistance R1.  The tapping contacts 15, 16 may be coupled together a fixed distance apart to vary the grid bias without changing the potential across the cell.  Alternatively, the contact 15 may be fixed at the negative end of resistance R2 and the contact 16 moved alone.  Condensers 17, 18 are connected across the relay contacts 6b and the relay winding 6a.  A circuit is described and shown for alternating-current mains, using an indirectly heated valve.

Title: Improvements in valve bags
IPC: B65D30/24

Abstract: 364,590. Valve bags. WINSKILL, J. W., of Colthrop Board & Paper Mills, Larkfield, near Maidstone, Kent. Oct. 6, 1930, No. 29820. [Class 94 (ii).] In a valve bag having a folded end comprising longitudinal flaps 10, 11 and end flaps 12, 13, a strip 15 of material, separate from the bag and adapted to form an inward extension of the valve, is adhered to and contacts with the inner faces of the flaps 10, 11 and the outer face of the flap 12. The bag is then creased and folded along the lines 16, the flaps 10, 11 being adhered together over their overlapping portions and also to the flap 13. In making the bag, the tubular blank, with its end folded as shown in Fig. 1, approaches a roller 21, Fig. 8, carrying counterweighted creasing blades 27 for forming the creases 16. Between the blades suction cups 28 are mounted and draw the lowermost strip from a pile 46 in a container 43 as they pass therebeneath, suction being applied at the appropriate moment through a pipe 29 leading from the cups, a central bore 30 in the shaft 23 of the roller, a connecting pile (not shown) and a valve 33 in communication with an exhausted chamber. A cam 36 on the shaft 23 engages a pivoted arm 35 connected to the valve to apply the suction, and remove it when the cups have carried the strip to a position above the end of the bag. The strip drops on to its place on the bag and is creased and pressed by the roller 21 and its co-operating roller.

Title: Process for producing a dihydrostreptomycin
IPC: C07H15/238
Filed: 1950-12-08
Abstract: A streptomycin-containing liquid obtained from Streptomyces griseus as described in Specification 610,570 is treated with activated charcoal and the streptomycin is eluted from the charcoal with dilute hydrochloric acid at 70 DEG  C.  The eluate is adjusted to a pH value of 6.5 with sodium hydroxide and then electrolytically reduced, adding hydrochloric acid until reduction is complete.  The catholyte is then mixed with an aqueous solution of the sodium salt of sulphated 3,9-diethyl tridecanol-6, and the precipitate is filtered off and dried.  It is then dissolved in methanol and impurities filtered off.  The filtrate is diluted with water and heated together with a neutral anion-exchange resin, and concentrated hydrochloric acid is added to maintain the pH value between 3 and 3.5 for half-an-hour.  The pH value is then allowed to rise between 5 and 5.5 and the resin filtered off.  The filtrate is then vacuum-distilled to remove the methanol and the residual solution is freeze-dried, yielding the hydrochloride of the dihydrostreptomycin.

Title: Improvements in or relating to the manufacture of light forms of concrete or artificial wood composed of loose or fibrous organic materials and cement, concrete or the like
IPC: C04B20/02
Filed: 1924-12-16
Abstract: 253,007. Novocrete &. Cement Products Co., Ltd., Broadway Trust Co., Ltd., Burney, C. D., and Temple, J. E. Dec. 16, 1924. Plastic compositions containing mineralized fibres and cement.-Artificial wood or light concrete consists of a mixture of cement &c. with fibrous material which has been subjected to a mineralizing or indurating treatment and to a treatment which reduces its tendency to change in volume with change of moisture content. The fibrous material may be sawdust, shavings, coir, cork, paper pulp, wood waste, sizal. &c. The mineralizing or indurating treatment consists in precipitating mineral matter in and on the fibrous material with the object of increasing the adhesion between it and the cement; suitable processes being those disclosed in Specification 244,178. Various methods of treating the fibrous material to reduce its tendency to change in volume are described. One such method consists in heating the material for several hours to 120‹ C. A second process consists in impregnating the material with water-repellant substances such as petroleum jelly, oils, resins, bitumen, waxes, or soaps, these substances being conveniently used in the form of emulsions. Insoluble soaps may be precipitated in and on the material by impregnating the latter firstly with a soluble soap ,solution and subsequently with a metallic salt solution, an excess of the latter being used which by subsequent treatment with a precipitating agent or by spontaneous decomposition effects the mineralization of the fibres. Ferrous and ferric chlorides, chromates, and bichromates and chromium and copper chlorides are referred to as suitable salts; the soap solution may be sodium or potassium stearate, oleate, or resinate. A third method of treatment consists in extracting the fibrous material before mineralization with a solvent which removes the more soluble bodies; suitable solvents are weak solutions of mineral or organic acids (e.g. acetic acid) or of alkalies (e.g. sodium or potassium hydroxide, carbonate, bicarbonate, or silicate, or calcium hydrate). A fourth process consists in treating the fibres with a, substance which combines with the cellulose or lignin and forms a hard impervious skin upon the fibres; ammoniacal copper solutions are suitable for this purpose. The Provisional Specification describes another method of treating the fibrous material, consisting in treatment with dehydrating agents such as anhydrous magnesium chloride. Specifications 236,450; 238,948, [Class 87 (i). Bricks &c.], 244.142, 245,812, 252,906, and 258,665 also are referred to.
