Title: Improvements in gas producers
IPC: C10J3/30
Filed: 1920-11-03
Abstract: 171,884. Wells, J. F. Nov. 3, 1920. Producers; coking processes.-In a gas-producer, the incandescent zone in which the fuel is oxidized to carbon dioxide is separated from the transformation zone in which the carbon dioxide is transformed to carbon monoxide, the hot gases from the incandescent zone in which solid, liquid, or gaseous fuel may be burned being passed through a shallow fuel bed in the transformation zone. Fuel is burned in the zone or compartment e in a blast of air from a pipe d and the hot combustion products pass around the fuel in the zone g heating the same and escaping through an outlet m, which is closed when the zone g is at a red heat. The gases generated when the combustion products are passed through the transformation zone are drawn through a grate h and outlet i. An auxiliary supply of air is admitted at j and liquid fuel may be injected through ports k. Fuel is supplied from a hopper n controlled by a flap valve r. Bituminous fuel, wood, or straw may be used instead of dry fuel such as coke or charcoal and the producer worked to obtain charcoal or coke as a product.

[Classes 100 (i) and 100 (ii).] In folding-mechanism of the kind in which folding-blades 27, 28, 29 on a cylinder 14 are operated by a rotating slotted disc 83 engaging arms 67, 68, 69 thereon so as to tuck the sheets between folding-rollers 33, 34, the disc is movably axially to an inoperative position and is replaced by a guide 113 completing the usual circular track 77 so that the folding-blades operate at intervals of more than one revolution of the cylinder 14 to fold off sheets which have been collected thereon. In the arrangement shown the blades are operated at alternate revolutions to fold off pairs of sheets collected on the cylinder. The disc 83 is fixed to a gear 89 meshing with a broad gear 106 on the shaft 18 of the cylinder 14, and its shaft 90 is movable endwise in the side frame 19 of the machine by means of a slidable bracket 104 engaging a collar 105 thereon. Fixed to the bracket 104 is a guide 113 which, when the disc 83 is moved axially to inoperative position, moves into position to fill the gap in the track 77 adjacent to the folding position. The bracket 104 is moved at the required periods by a grooved cam 131 rotated by gearing 144, 143 from the shaft 18, a pin 133 riding in the cam groove being mounted on a sliding bar 127 connected by a link 125 and bell-crank lever 124 to the bracket. The collecting pins 43, 44, 45 corresponding to the blades 27, 28, 29 are operated by rollers 58, 59, 60 carried by crank arms 55, 56, 57 and running in a cam groove 159 in the usual way. The part 171 of the groove 159 operating to retract the pins when the sheets carried thereby are being folded off is formed on a slidable block 167, which also has an arc-shaped groove 170 adapted to replace the part 171 during the cylinder revolution when the pins are collecting and therefore are not retracted, the corresponding folding- blade being also inoperative. The block 167 is operated from a suitably designed grooved cam disc 178 through a bell-crank lever 175, the disc being driven from the shaft 18 similarly to the disc 131.

Title: Strip material feed control
IPC: G03B1/42
Filed: 1954-10-28
Abstract: 754,415. Feeding webs. RADIO CORPORATION OF AMERICA. Oct. 28, 1954 [Nov. 2, 1953], No. 31157/54. Class 100 (1). [Also in Group XX] Apparatus for controlling the movement of a web comprises reels for supplying or receiving the web and three loop-forming members arranged two on one side and one on the other side of the web so as to frictionally grip the web and exert on the web a force affecting the longitudinal motion of the web, the amount of the force being dependent upon the loop size. As shown in Fig. 1 a film 10 intermittently fed from a reel 12 by sprockets 14 is fed past rollers 22 to form a loop L. The film is then guided around studs 30, 32, which may be of aluminium, and a stud 34 preferably of rubber, to a receiving reel 16 which exerts a constant torque on the film. When the loop is large the film is free to move between the studs 30, 32, 34, but as the loop L decreases in size the film is drawn more tightly between the studs 30, 32, 34 so that the frictional force exerted thereby overcomes the torque applied by the reel 16. In the embodiment shown in Fig. 3 the film 10 is drawn off a reel 17 which exerts a constant torque on the film tending to prevent the feed. As the size of the loop diminishes the film is pressed against a rotating roller 31 so that the torque exerted by the reel 17 is overcome.

Title: System for positioning a microimage carrier in a microform reader
IPC: G03B21/11
Filed: 1973-07-02
Abstract: 1381216 Microimage readers NCR CORP 2 July 1973 [14 July 1972] 31402/73 Heading G2J In a microimage reader the image carrier and part of the reader form two co-operating members, one having a positioning means co-operating with an array of positioning means on the other, such that movement of the carrier can be effected in a stepwise manner. As shown, the microimage carrier 33 has a portion 34 carrying a series of microimages 35, one of which is brought below a lens assembly 30 for projection on to a screen. Contiguous with the portion 34 is a positioning portion formed by upper and lower plate members 36 and 39, the latter having an array of rounded projections 37 formed on the underside. These projections are arranged in columns and rows corresponding to the columns and rows of the microimages 35. A rail 45 is secured to the table 20 on which the apparatus stands, and defines the X direction of movement. A groove 48 runs along the length of the rail, and receives a row of projections 37. When such a row is seated in groove 48, the carrier 33 is restrained from free horizontal movement in the Y direction, but can slide in the X direction. When it is desired to move carrier 33 in the Y direction, a slight force applied to the handle 38 lifts the row of projections 37 from the groove 48 and enables another row to be brought into engagement with the groove. Thus the carrier is easily slidable in the X direction, but moves only in controlled steps in the Y direction.
