[Class 55 (ii)] Improved coke and tar are obtained by carbonizing mixtures of bituminous coal and materials which reduce the melting point of its ash forming constituents, the quantity of the added substances not exceeding 2 per cent by weight of the coal, being sufficient to sinter but not to flux the ash forming constituents. Specified additions comprise sodium lead or calcium borate, sodium chloride, sulphate, silicate phosphate, boric acid, magnesium sulphate or mixtures of these. The carbonizing temperature may be higher or lower than the volatilizing temperature of the added material, and the fuel may be steamed to form water gas. The tar obtained may be mixed with oil with or without coal dust to form a mobile fuel. In an example Durham coal with 1 per cent each of borax and sodium chloride was carbonized at 1050- 1200‹ C., and in a second example, 33 per cent semi-anthracite and 67 per cent Welsh steam coal with 0À5 per cent each of borax and sodium chloride was carbonized at 700‹ C.

Abstract: 688,658. Paper bags. MEDWAY PAPER SACKS, Ltd., and DAVIS, R. Nov. 9, 1951 [Sept. 29, 1950], No. 23874/50. Class 94(ii) A multi-ply paper sack having block-folded ends, with or without a valve, has an additional leaf of paper or other material covering an inner folded end and adhered to the opposed walls of the sack tube along its longer edges. The inner ply 1, Figs. 1, 8, 9, of the five-ply bag described is shown with the additional leaves 22 at both ends, with alternative methods of attachment. The outer edges of the lower leaf are attached just inside the final fold creases 18, while the inner edges of the upper leaf are attached just outside the creases 18, so that when the sack is extended they are disposed as shown in Fig. 9. In a valved end, the leaf 22 is provided with a slot 23 to take the filling nozzle, and the slot may be covered by a sealing flap 26, Fig. 17, adhered to the margin 27 of the slot nearest the valve opening. The leaf 22 may. extend up the end walls of the sack, the extensions being pasted at the corners to the inside wall of the tube as shown in Fig. 17, in dotted line, and Figs. 18, 19, 20, 21 (not shown). At the bag ends, after folding, the ends of each ply either abut or are separated by a gap each ply of each side flap being adhered marginally to an adjacent ply of the same or of the other flap or to the additional internal leaf or a cover strip. The ends of each ply, 1 ... 5, Fig. 14, are thus bridged by a butt-strap. The outer ply 5 is bridged by a cover strip 24, ply 4 by the part 3a of ply 3, ply 3 by the part 2a of ply 2, ply 2 by the part la of ply 1, and ply 1 by the internal leaf 22. In order that the plies in the side flaps may be interleaved as described, plies 4, 5, Fig. 11, are slit at 21 so that the upper ends of these plies may be folded outside the lower ends of all the plies, which are folded over the upper ends of plies 1, 2, 3. The area in each V of the bag end in which the full number of five plies are not present is reinforced by a small rectangular gusset strap adhered to the outside of the sack tube, Figs. 6, 7 (not shown).

The bar is wedged between and is mechanically supported by electrically conducting wires 3, which are soldered to the ends of elements 2. The wires are embedded in glass 5 within a holder 4 and may be used to connect the elements in a Wheatstone bridge. Change in mechanical stress on the bar changes the resistance of the elements. Alternatively the elements may generate a signal. A transistor may also be diffused on the bar to amplify a signal derived from the elements 2. The bar may be mounted within a rectangle frame, Figs. 2, 3 (not shown) being attached at each end thereto by conductor wires, and capable of measuring tensile forces applied to the frame.

Abstract: 444,460. Precombustion chambers. DAIMLER - BENZ AKT. - GES., Unterturkheim, Stuttgart, Germany. Aug. 30, 1935, No. 24250. Convention date, Aug. 30, 1934. [Class 7 (iii)] In an oil engine the whole or a substantial part of a precombustion chamber is formed as a displaceable insertion piece so that the cross-section of the passage through which the contents of the chamber enter the engine .cylinder can be changed. In the construction shown in Figs. 1 and 2, the precombustion chamber g is formed in a spherical member d which is disposed in insertions b<1>, b2 in the cylinder head and controlled by a lever e. The member has diametrically opposed openings h<1>, h<2> and h3, h4 which can be rotated to face the outlet of the fuel injector c and a passage leading to the cylinder. During normal running the opening h<1> is adjacent the injector and the opening h<2>, which preferably consists of several bores arranged in a circle, is adjacent the cylinder, whilst during starting, the member d is turned through a right-angle to bring the larger opening h<4> adjacent the cylinder and permit fuel to be injected directly into the cylinder. A small ante-chamber k is formed between the member d and a ring-shaped projection l on the insertion b<2>, and the projection screens the member d from the hot gases in the cylinder. In Fig. 4, only the lower constricted part g<2> of the precombustion chamber is formed in the insertion piece d<1>. In modified constructions, (1) the displaceable insertion piece is formed by a slide valve provided with separate transfer passages ; (2) the displacement is performed automatically by a starting device or is related to the speed, load, or temperature of the engine ; and (3) the passage between the precombustion chamber and the cylinder is formed by a slot in the displaceable insertion arranged so as to provide a wide passage in the starting position, a narrow passage in the normal running position, and a passage of intermediate size in other positions.
