Abstract: 123,715. Sturtevant Mill Co., (Assignees of Sturtevant, T. J.). Feb. 23, 1918, [Convention date]. Impact pulverizers.-The casing of an impact pulverizer is formed in two parts hinged together on a vertical axis adjacent to the horizontal shaft of the beaters, the arrangement rendering the beaters &c. accessible for removal or repair; further, the grid is formed in two sections which are mounted on the two parts of the casing respectively, so that, on opening the door, hard obstructions &c. fall out of the grid or can be discharged by operating the beaters. The casing is formed with a stationary part 1 and a hinged part or door 3 which is mounted on a vertical pivot 7 arranged near the shaft 51 carrying the beaters 61. The door may be secured by catches 85, Fig. 1, which are mounted on an angle-bar 83 on the casing 1 and engage an angle-bar 81 on the door. The beater-shaft is journaled in bosses 53 which are mounted in recesses in the side walls 9 of the chamber 1, the recesses being formed open at the sides to permit the removal of the shaft. The bosses are secured by bolts 59 passing through flanges 57 on the bosses. On detaching the bolts 59 and the bar 83, the beater-shaft and the beaters can be removed bodily. The beaters are pivoted on pins 63 which pass through holes 67 in spaced plates 65 and are secured by cotters. The plates are keyed to the beater-shaft and are united. by rivets 71. To permit of radial adjustment of the rods 63, the plates are provided with a number of holes 67 at different distances from the beatershaft. The grid is formed of bars 27, 37 mounted in the chamber 1, and bars 45 mounted in the door 3. The bars 27 are inserted through holes in the side walls 9 and flanges 17 in the rear wall 11, and are secured at the ends by detachable plates 29. The rear wall 11 is formed with a rib 33, Fig. 2, having seats for supporting the bars. The bars 37, 45 are received by holes in remov- .able plates 39, 47 which are secured to the side walls of the chamber 1 and door 3 respectively, the plates 47 forming continuations of the plates 39 when the door is closed. The inner ends of the plates 39 engage seats 43 on the flanges 17. A renewable liner 23, Fig. 2, is provided for the feed-opening 19.

A circuit arrangement comprises a television pick-up tube including a photo-cathode 1 and a storage electrode on which the photo-electrons are arranged to impinge and which is in the form of a double.sided target 2 arranged to be scanned on one side by an electron beam, the other side of the target being covered with a thin insulating layer 3 and a thin conducting layer 4, means being provided for maintaining the conducting layer 4 at a potential different from the potential at which the double sided target 2 is stabilized by the scanning beam. In operation the photo-electrons penetrate the conducting layer 4, which may be of aluminium or beryllium, and the insulating layer 3, which may be of silica or magnesium fluoride, and are brought to rest in the target 2 which may be of glass. The bombardment-induced conductivity allows a current to flow between the target 2 and the conducting layer 4 charging the target positive or negative according to the potential of the layer 4; the potential of the layer 4 may be varied to form a gain control. The target 2 may be scanned by a high velocity beam or a low velocity beam, and the output may be derived from the layer 4 or from the returning electrons of the scanning beam. Specifications 597,532 and 655,290 are referred to. Specification 655,291 also is referred to in the Provisional Specification.

The edges of the two panels outside the lines of stitches are bent inwards, to form lips which can fit together. With the lips so engaged, zig-zag stitching Z, Fig 1, is used to connect the front and back panels. An elliptical base panel, Fig 4 (not shown), having a similar sewing line marked adjacent its edge, is sewn to a like panel, stuffed, and strengthened with cardboard. The base so made is sewn into the open bottom of the doll, which also is stuffed. In another form, a sheet is marked for arms 4, 5, Fig 6, legs 6, 7, &c to be cut-out and then sewn together, the arms, &c being sewn to the trunk 8, 9, of the doll. The marked sewing lines may be formed by lines of holes. The sheet material may be paper coated with plastics, and the sewing material may be wool or cotton.

Filed: 1918-10-31
Abstract: 125,562. Pitney, H. A. Oct 31, 1918. Valve-gear.-A double-acting two-stroke cylinder D is scavenged and charged by a co-axial pump E the piston of which compresses scavenging-air with its bottom face and combustible mixture, or air which is afterwards carburetted, with its top face. In the position of the parts as shown in Fig. 1, a portion of the scavenging-air will be transferred through the interior of the pistons and through a port K in the piston A, a registering port in the cylinder wall and a transfer pipe L to a port controlled by a valve S in the upper end of the cylinder. Similarly, when the pistons are at the opposite ends of the cylinders, the remainder of the air in the pistons will be transferred to the lower end of the power cylinder. The charges compressed in the upper end of the pump are delivered to a reservoir which communicates with the ends of the working cylinder D through mechanically-operated valves 0, P adjacent to the air-inlet valves S. The valves S are held in their open positions by light springs and are closed by the cylinder pressure during the expansion strokes and also by rocking-levers X during movement of the latter to open the mixture valves. The rocking-levers are carried by rods actuated by face-cams on a disk U.

The preheated agglomerates may be briquetted before being coked. Reagents, e.g. lime or sodium silicate may be added during the agglomerating step, to aid in separating pyrite from the coal, and an optional aeration step may be applied to the oil and water dispersion before agglomerating, to upgrade the coal fines. The fines may be those normally produced in mining, being about - 14 mesh (Tyler), or coal feed comprising about 80% less than # inch size may be subjected to the agitation step, in which only - 10 mesh agglomerates, the mixture of agglomerates and larger pieces going on to coking as before.
