Abstract: 822,495. Fuel briquettes. BRIKO N.V. May 10, 1956 [May 12, 1955], No. 14625/56. Class 50. Fuel briquettes are made by treating lignite at a temperature of at least 55‹ C., preferably above 70‹ C., e.g. 100‹ to 120‹ C., with a small amount of a lower carboxylic acid, the product being pressed into briquettes, or first mixed, as a binding agent, with another fuel and then pressed. Acetic acid is the preferred acid for the treatment, being used as a concentrated aqueous solution of 80 per cent acetic acid, in an amount of 15 c.c. per kilogram of lignite which is ground so that the greater part is composed of 0.5 to 1.0 m.m. granules, particles of 3 m.m. being tolerated. The acid-treated lignite may be mixed with pit coal dust, 90 parts of coal to 10 parts of acid-treated lignite being mentioned as an example. Before the treatment with acetic acid, a carbohydrate, or a carbohydrate ether, may be added to the lignite, e.g. potato starch, sago, dextrin, corn meal, soybean meal, in the proportion of one part by weight of carbohydrate to from 10 to 100 parts of lignite. Cellulose ethers, e.g. methyl-cellulose and carboxy-methyl-cellulose, may be added to the lignite in quantity not exceeding 5 per cent of the weight of the lignite. Melted solid paraffin wax or liquid paraffin wax may be added to the lignite preferably after the treatment of the lignite with acetic acid. Molasses may be added to the lignite, preferably in admixture with the acetic acid, in amounts of 30 to 40 grams per kilogram of lignite. Examples are given of processes in which the mass to be briquetted is heated by live steam to about 85-90‹ C., or the temperature needed for briquetting is obtained by heating the pitcoal dust with live steam to 140‹ C. before mixing with the treated lignite.

Title: Improved vehicle for combined propulsion by wheels and endless tracks
IPC: B62D55/02
Filed: 1937-05-29
Abstract: 480,639. Endless -track vehicles. KEGRESSE, A. May 29, 1937, No. 14950. Convention date, 'June 2, 1936. [Classes 79 (i) and 79 (ii)] A vehicle is mounted at the front on combined driving and steering wheels and at the rear alternatively on endless tracks, which are driven or on road wheels which are not driven, In the construction shown the track pulleys 10, 11 are mounted on the chassis frame 1 and the load bearing rollers 12 and the rear road wheels 16 are movable up and down, to bring the tracks or the rear wheels into use, by rocking a shaft 20 carrying three-armed levers 23, 24, 25 at each end. The shaft 20 is connected to the' frame 1 by springs 21 which thus serve as suspension springs when the vehicle is running on the tracks, and also on the rear wheels. Levers 18, loosely mounted on the shaft 20, carry axles 17 for the road wheels 16 at one end and axles 14 at the other end for levers 15 carrying equalizing levers 13 on which the track rollers 12 are mounted. The levers 18 are formed with bosses 37, 38 adapted to engage sockets 39, 40 on the chassis frame to determine the upper positions of the axles 14, 17. Thus, when the shaft 20 is rotated in one direction the arms 24 raise the bosses 37 and hold them against the sockets 39, as shown in Fig. 3, so that the track rollers 12 are clear of the ground and the wheels 16 are in contact with the ground ; when the shaft 20 is rotated in the other direction the bosses 37 are lowered and the bosses 38 are raised and held against the sockets 40 so that the wheels 16 are clear of the ground and the rollers 12 support the rear part of the vehicle through the track. The idler pulleys 11 of the track are carried by a shaft 29 slidablymounted in the chassis frame and connected by links 30 to the arms 25 on the shaft 20, so that as the track rollers 12 are raised from the ground the pulleys 11 are moved outwards to take up the slack in the track and raise it clear of the ground. Each pulley 11 is also movable relatively to the shaft 29 to tension the track, the pulley axle 33 being carried by an arm 32 loosely mounted on the shaft 29 and adapted to be locked to a sector plate 31 on the shaft by a pin 35 engaging a hole in the arm and one of a series of holes in the sector. The arm 32 is formed, with a manipulating handle 34. The shaft 20 is rocked in either direction by a link 27 connected to a crank 28 operated from the gearbox 3 by a shaft 6, reversing gearing 41, and screw-and-nut gearing 46, 47. When the vehicle is travelling on front and rear wheels the front wheels are driven from the gear-box 3 at a relatively high speed, but when the vehicle is travelling on the front wheels and the tracks the wheels and the tracks are driven, but the wheels are driven through a reduction gear 4 to lower their speed to correspond with that of the tracks.

Title: Improvements in flame cutting machines
IPC: B23K7/00
Filed: 1925-06-10
Abstract: 253,714. Hancock, L. J. June 10, 1925. Perforating and dividing by fusion. - In a flame cutting machine of the kind described in Specification 226,846, the tracer arm and blowpipe-carrying arm are mounted on a carriage traversable by an electric motor on rails alongside the tracer table and work bed in order to make continuous cuts of indefinite length in the side frames of locomotives &c. The integral tracer and pipe arms 17, 18 are pivoted at 19 to a gate 16, which is pivoted on a rost 15 mounted on a wheel carriage 14 traversable on a channel- or .H-section girder 2 through gearing 22 from an electric motor carried thereby. The pattern table 13 is carried by brackets 12 secured to the shafts of worm wheels 11, and may be tilted, so as to allow heavy work to be placed on the bed 1, by a hand wheel through bevel gear 8, 9 and worms 10. The tracer wheel is driven by a second electric motor and is guided by hand. In order that the carriage may be traversed when 'the limit of the normal reach of the arms has been attained, the traversing motor may be switched in by hand. automatically. For the latter purpose a plate 23 on the post 15 has a pair of contacts 24, 25 and a pivot 33 for a segment 26 and a telescopic arm 29, the other end of which is pivoted at 34 to the arm 17. The segment is connected to the arm 29 by a spring 30 and is normally fixed by a ball 31 pressed by a blade spring on the plate into the central notch 32. Just before the point is reached at which movement of the post 15 is required to continue the cut, the tension of the spring 30 overcomes the pressure of the ball and the segment is moved so that the ball engages one or other of the side notches, and this connects the contacts 24. 27 or 25, 28 and so operates the traversing motor in forward or reverse direction. When the tracer arm is moved in the reverse direction, i.e. round a curve, the spring again overcomes the ball and the segment is snapped over into central position so as to stop the motor. The bed plate is in sections so as to vary the length of travel of the machine. The tracer and pipe arms may be set to cut on a line parallel with the rails. Stops are provided on the carriage to prevent it overunning the track.
