Long independant sections of double lengths of rails R are engaged by rollers on a train comprising a hoist wagon D1, a winch wagon C1, intermediate wagons A1 and a centre wagon Bl and are run the length of the train by movement of the wagons, the first pair of rails being loaded towards the centre of the wagons and successive pairs outside the prior pairs, the rollers being substituted by fixed supports for transport. The ends of the rails are raised by a crane on the hoist wagon and led through a guide spacer having rollers mounted on a frame articulated to the end of the hoist wagon to prevent twisting of the rails. Vertically and horizontally mounted rollers guide the rails at the entry of the hoist wagon and of the winch wagon, the vertical rollers of the latter being transversely adjustable to lead the rails towards the centreline of the wagon. The end of one rail is clamped to, and the end of the other rails is supported in a guide-carriage El having the wheels where double flanges engage grooves running the length of the intermediate and centre wagons, thus guiding the leading ends of the two rails the length of the train as the rails move over horizontal rollers on the wagons and pass between vertical guide pins. When the first pair of rails is loaded, they are clamped by their base flanges to the centre wagon. The second and subsequent pairs of rails are similarly loaded outwards of the prior loaded pair, the advancing ends being guided by a carriage running on the prior loaded rails. The last pair of rails is moved longitudinally by winches on the winch wagon which also carries a generator providing power for the electric winches and the hoist. For transport the horizontal guide rollers on the intermediate wagons are retracted and the rails rest on fixed supports on the wagons.

Title: Amplification of electric waves by space discharge devices
IPC: H03F1/50
Filed: 1941-04-25
Abstract: 545,343. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd. April 25, 1941, No. 5354. Convention date, April 26, 1940. [Class 40 (v)] An interstage coupling for a wide frequency range comprises two resistances R1, R2 in series between anode and cathode with the resistance R1 nearer to the anode shunted by an inductance L and the other resistance R2 shunted by a condenser C1 and two blocking condensers one C5 between the anode and the succeeding grid for frequencies in the upper part of the range and the other C6 between the junction of the anode resistances R1, R2 and a tapping on the grid resistance and having a low reactance for the lower frequencies of the range. Fig. 1 shows an arrangement in which resistance R1 is constituted by an M-derived law-pass filter 12 terminated in a resistance 11 and is such that L/C1 =R1, R2. Preferably the inductance L is connected in shunt to resistance 11 so as not to increase the inherent self capacity C0. The screen voltage is taken from the point a so that it is at substantially anode potential to secure high gain. Fig. 3 shows a modification of the arrangement to avoid degenerative feedback at low frequencies when the self biasing combination R3, C3 is used. Compensation is effected by so proportioning the decoupling resistance R4 and condenser C4 that C4, R4 = C3, R3. The Specification gives quantitative data for an amplifier operating from 40 cycles to 3 megacycles.

Title: Improvements in or relating to the preparation of nutritive media for yeast
IPC: C12N1/18
Filed: 1930-02-18
Abstract: A nutrient solution suitable for growing baking yeast is made from molasses and feeding stuffs rich in protein by combining the hydrolysis of the protein of the feeding stuffs with the preparatory treatment of the molasses.  The comminuted feeding stuffs are treated at boiling temperature with dilute sulphuric acid, the acid content of which is somewhat greater than the quantity usually required for the preparatory treatment of molasses until the protein has been rendered completely soluble, after which the mash of hydrolyzed feeding stuffs are added to the molasses solution diluted to 20 DEG Bg. and the whole mash after standing for some time at 80 to 85 DEG C. is filtered.  An example is given of the use of peanut cake, the acidity of the mash obtained being reduced by the addition of ammonia.

Title: Improvements in and relating to metal seals for wire and the like
IPC: G09F3/03
Filed: 1932-02-26
Abstract: 389,268. Bale-tie fasteners. GATEHOUSE, E. A., 22, Essex Street, Strand, and KING, W., 50, Rodenhurst Road, Clapham Park, both in London. Feb. 26, 1932, No. 5781. [Class 94 (i).] A metal seal of the type comprising a multiplebore tube-like structure for connecting together the ends of a wire box strap, or any two wires is provided with oppositely-disposed longitudinal internal projections or indentations which substantially divide the tube into two parts, each intended for the reception of a single wire, the space between the projections being insufficient to allow the passage of the wire from one part of the bore to the other. The seal may be formed so that the two wires are kept apart by a separating wall. As shown in Fig. 7, the seal is formed by folding a sheet metal strip e around a former f, which may comprise two wires laid side by side. The folded strip, with or without the former, is placed on an anvil g, having a central rib g<2>, and a die g3 is pressed on to the strip. Fig. 1 shows the finished seal, which is attached to one end of a wire strap by passing the end of the strap through one of the channels c and then corrugating the channel and wire and/or bending the protruding end of the wire into a hook. Fig. 13 shows another method of forming the seal, the two channels being completely divided. The longitudinal indentations are formed as before, but in this case may be formed at the ends only. In attaching the seal to one end of a wire, the channel holding that end, as well as the other channel which is corrugated in the sealing process, may be corrugated at the two ends only, so as to leave a central blank space for a trade mark, as shown in Fig. 19. Specification 386,749 is referred to.
