Title: Improvements in Carburetters for Paraffin and like Heavy Oils.
Inventor: DAVIS FITZWILLIAM RICHARD
Filed: 1911-10-31
Granted: 1912-10-31
Abstract: 24,106. Davis, F. R. Oct. 31. Spray carburettors. - The mixture is passed through an exhaust - heated chamber B containing a baffle in the form of a double helix J. The walls of the chamber have ribs to take up the heat from the exhaust. Two nozzles are used, one for petrol at starting, and the other for paraffin. The stem on which the helix is formed extends into the spraying-chamber A between the nozzles. The helix is discontinuous to form a space K at the hottest part of the heating - chamber. The spraying - chamber and the casing D are detachable from the chamber B, which is secured to the suction pipe; with this separation, the helix may be interchanged. The nozzles are arranged under the passages in the helical baffle. The Provisional Specification describes an air-valve formed with teeth on its periphery with which a pinion engages.

Abstract: 28,260. Davies, E. L. Dec. 15. Moulds.-A bearing for mill rolls, pinions, &c. is made with a steel or iron body to which a wearing surface of brass, bronze, &c. is united by cast. ing with the aid of a flux. The body, previously cleansed, is either dipped into a bath of molten flux, or is heated to a suitable temperature and sprinkled with the flux in powdered form. The body a is placed in a mould face downwards, and the molten brass &c. is poured in at d, an outlet e being provided at each side of the opposite end of the mould. If the body is not cut to its correct shape before the brass is cast, it may be supported in the mould by its side edges. Instead of being of sand &c., either the lower part or both parts of the mould may consist of metal blocks. The upper box f of the mould is secured to the lower box by means of lugs g, clamps h, and wedges i. The mould is heated to a temperature of 200- 300‹ C. The bearing may be cast face upwards, in which case the supports j are unnecessary. Specifications 17,660/04, 13,811/05, 15,675/05, and 21,504/10 are referred to.

Title: Improvements in Calculating Apparatus.
Filed: 1912-06-21
Granted: 1913-01-30
Abstract: 14,562. Vermehren, J., and Aktieselskabet Vermehrens Regnemackiner. June 21. Multiplying-apparatus.-The action of setting the multiplicand and multiplier positions pairs of rollers provided with cams corresponding to the units and tens respectively of each denominational product, so that certain pivoted rods or bars are selected by the cams and their free ends brought into alinement: the selected bars thus virtually form teeth, such as those of a rack, and the teeth are summed by receiving- wheels mounted upon a travelling carriage which is moved across the machine at each operation. One " group " of the machine is shown in Fig. 3, and is sufficient to permit the multiplication of a four-figure multiplicand by one of the figures of the multiplier. When the multiplicand is set simultaneously on each of the three groups, A. B, C, Fig. 1, by means of slides m and pointers n, cam-shafts k are rotated and each one thrusts to the right a selected pair of rollers so that their bevel driving-wheel i engages with the corresponding wheel o on the shaft p. The digits of the multiplier are then set by means of the three slides s and pointers t; the shafts p are thereby rotated and turn the selected pair of rollers, so that the cams thereon select as many pivoted rods a, Fig. 3, as correspond to each partial denominational product, and push them by means of projections v, so that the lower ends of the rods are brought into alinement with toothed receiving-wheels F attached to the numeral drums E. It will be seen from Fig. 3, that the rods representing the tens of one such partial product and those representing the units of the next higher partial product are moved into the same alinement. The lower ends of the bars are pointed and thus virtually form rack-teeth which are summed by the receiving-wheels F when the carriage in which tne wheels are mounted is moved across the machine by the operating-handle through screw- and-nut mechanism H, G. The receiving-wheel which sums the teeth of one denomination of, say the group A, sums the teeth of the next lower denomination in the group B, as the elements a, b, c, d of the second group are displaced with reference to the similar elements of the group A. Transfer mechanism.-Projections I, Fig. 3, on the numeral-drums E at transfer rock pivoted plates K and set, through wheels N, O, and pawl-and-rachet mechanism, transfer camcylinders, P, Fig. 1, adapted to co-operate with and set one or more of the pivoted bars R, T; the mechanism being similar to the cylinders and bars alreadv described. The cams x on the cylinders P are displaced relatively to one another so that the carried figures represented by the displaced bars are summed successively by the receiving wheels F during their movement across the machine. The cylinders P are re-set, when the numeral-drums are zeroized by means not described, through the projections I, plates K, &c., the pawls being reversed so as to rotate the cylinders P in the opposite direction.

Granted: 1913-02-06
Abstract: 24,125. Sandberg, E. S., and Sundblad, G. K. Oct. 30, 1911, [Convention date]. Carbonizing processes and apparatus; retorts. -The destructive distillation of organic matters suspended or dissolved in liquids such as waste lye from the manufacture of wood pulp is effected by evaporating the liquid in a thin layer and partly carbonizing the residue on an externally heated surface, and then completing the carbonization in an externally heated screw-feeder, an ordinary retort, or the like. In the apparatus shown, the liquid is supplied by a rotating pipe 4 to a conical surface 6, which is heated externally to 400-500‹ C. by the gases from the furnace 16, and the residue is removed by means of rotating scrapers and passed through externally heated screw-feeders 8, 11. The products of evaporation and distillation from the surface 6 and the screw-feeders escape together through a pipe 15 leading from the upper screw-feeder. Reference is made to a known process in which the waste lye alone is completely carbonized in a thin .layer on an externally heated surface.

Roller mills; feeding-devices for granular and like materials.-In roller flour-milling and like machinery in which the lower edge of the side A of the feed-box D terminates some distance above the feed-roll B, and a low feedgate C hinged at its upper end C<1> forms or acts as the lower part of the hopper side, the side A, which is stationary during the feeding process, is hinged at its upper end so as to be adjustable towards or from the opposite side of the box D, and long fingers or teeth a are formed on its lower edge, or the teeth may be attached to and form part of the gate C. The gate may be hinged at its upper edge to the lower edge of the side A, and the connexion may be such that after a certain angular movement of the gate any further movement carries the side A with it. Any suitable adjusting, setting, and spring-controlled devices may be combined with the gate C. In the device shown, an eye-bolt W hinged to the gate carries an adjustable bush F having end collars F<1>, F<2>, and the forked end of an arm G secured to a rotatable shaft H embraces the bush. A spring K is connected at one end to an extension c of the gate, and at the other end to an adjustable screw L on the arm G. The side A may be vibrated or have short and sharp transverse reciprocations imparted to it to facilitate feeding. The Provisional Specification states also that the low gate is preferably suspended as described in Specification 14,046/10, and that it may carry a serrated or other plate as described in Specification 26,940/10.

Alternatively, the cam-disks may be toothed around their entire periphery, in which case it will not be necessary to disengage the connecting- means f, g, e upon the rotation of the operating - handle, because all the disks of both groups undergo the same movement, and no relative movement then takes place between the cam-disks and pin-wheels.
