Abstract: 200,038. Haddan, A. J. H., (National Cash Register Co.). March 29, 1922. Hammer-impression arrangements; aligning for impression.-In a cash register machine, feeding and impression devices for a record or check strip comprise fast and loose pinions mounted on the driving-shaft and co-operating with pinions on a sprindle which can be moved longitudinally to disable the devices; impression and feeding devices for a detail strip aligning-devices for type-wheels, and ink-ribbon mechanism are also described. The check strip 248 passes between printing and impression rollers 253, 254, the roller 254 being secured to a spindle 265 which is coupled by a pin 271 to a sleeve 266 provided with a pinion 267 engaging a pinion 268 on the roller 253. The driving-shaft 27 carries a fast pinion 263a and a loose pinion 263b cooperating with pinions 264 on the spindle 265, the pinion 263b carrying arms 285, 286, for operating a platen 259 and a knife 262. Normally the pinions 263<a>, 263b mesh with the pinions 264, and drive is communicated to the cams, but when the spindle is pulled outward by means of a knob 275, the left-hand pinion 264 meshes with the pinion 263b and the drive is disabled. A stationary pin 400 co-operates with a slot in the roller 254 to prevent movement of the roller when the drive is disabled. A disc 401 secured to the pinion 263<b> is provided with a gap which permits lateral movement of the pinions 264 only when the driving-shaft is in normal position. The cams co-operate with a spring 287 to rock a lever 286 provided with a pin 279 engaging an arm 278 on the platen 259; the sliding knife 262 is operated by arms 293, Fig. 4 on a shaft 294 provided with an arm 296 engaging the lever 280. A ratchet-wheel feed and a platen 242 for the detail strip are operated by a three-armed lever 227 rocked by a lever 224 and a cam 221 on the driving-shaft. One arm of the three-armed lever is connected by a link 230 to a bell-crank 231 carrying a pawl 236 which operates a ratchetwheel 237 on the feed-roller 217 for the detail strip. The platen 242 engages a pin 244 on the three-armed lever, engagement being maintained by a spring 245. An arm 313 for aligning the type-wheels is rocked into engagement with gears 312 by means of the arm 317 of the three-armed lever. Ink-ribbon mechanism.-A ratchet-feed device for an endless ink-ribbon is operated by a link 235 having pin-and-slot connection 234 with the bell-crank 231, the feed-movement being limited by engagement of an arm 309 with a shoulder 311 on the link. For imparting an increased feedmovement to the ink-ribbon to prevent the cross seam thereof from coming to rest at the printing line, the ink ribbon is provided with buttons adapted to rock the arm 309 away from the shoulder 311.

Title: Improvements in or relating to methods of and apparatus for producing a gas or mixture of gases suitable for use in the heat-treatment of metals
IPC: C01B3/38
Filed: 1943-12-06
Abstract: 573,445. Gas mixtures. SHEPHERD, G. R. (Westinghouse Electric International Co.). Dec. 6, 1943, No. 20343. [Classes 51 (ii) and 55 (ii)] An atmosphere of carbon monoxide, nitrogen and hydrogen with possibly some methane and small amounts of water vapour and carbon dioxide and suitable for use in the heat treatment of metals, is obtained by continuously reacting fuel gas, particularly town's gas, and oxygen-containing gas, the proportion of the latter being varied so that free carbon is alternately separated from and taken up by the reacting gases. Apparatus may comprise an electrically heated chamber 3 containing nickel shot or other catalyst 12 to which the supply gases mixed in a chamber 22 are fed through a pipe 9 having constant pressure pump equipment 24 and constant flow equipment 27, the product gas issuing through a pipe 10, cooler 32 and water separator 33. A byepass 40 under the control of a solenoid-operated valve 41 admits additional air to the supply mixture when the pressure at the inlet to the reaction chamber, increasing owing to carbon deposition, reaches a preset value. The chamber is initially primed by utilizing a rich supply mixture and the product gas may be vented through a pipe 47. In an example, rich and lean supply mixtures of air and town's gas in the ratios of .6 to 1 and 1 to 1 yielded product gases of the following constituents respectively : carbon monoxide 16.8 and 21.4 per cent, hydrogen 60.6 and 44.7 per cent, methane 2 and 1.8 per cent, the balance being nitrogen, and the reaction temperature being about 1950‹ F. A modified apparatus provides a reversal of flow at each variation in the supply mixture which is brought about by a device responsive to the differential pressure between the supply and outlet pipes.

Filed: 1925-08-14
Abstract: 261,103. Standard Telephones & Cables, Ltd., (formerly Western Electric Co., Ltd.), (Turkhud, B. A.). Aug. 14,1925. Automatic and semi-automatic exchange systems.-An operator, upon seizing a long-distance toll trunk, sends ringing current thereover to energize a line relay which causes the trunk to be extended to a register-controller and connects a thermionic valve to the trunk for the purpose of repeating incoming impulses to the registercontroller. The arrangement may be employed for working over both physical and phantom trunk circuits. The trunk may terminate in the banks of line-finders as illustrated, or in group selectors, in which case the digit counting apparatus by which the talking circuit is completed at the proper time is omitted. Fig. 1 shows an arrangement employing dialling over a simplex circuit. Line relay A energizes in response to ringing current, locks and connects up relays B, C. Relay C locks, connects up relay D, thus releasing relays A, B, closes the filament circuit of the valve and connects the grid and its associated battery to the simplex trunk circuit. Relay F energizes in the anode circuit, and the grid circuit is so adjusted that relay F falls back when the trunk circuit is interrupted, and impulses are repeated over the loop to the registercontroller. Relay G is slow to energize, and pulls up at the end of each impulse train, connecting up relay N which controls a chain of counting relays of the " two per impulse " kind. Relay E is energized at the first impulse to replace the repeating coil by a non-inductive resistance. When all the digits have been dialled, the last counting relay M6 energizes and closes a circuit for relay R, which locks, switches forward the talking circuit and connects up relay J by which relays C, D, E, F and the counting relays are released. The operator sends ringing current to release the connection, and line relay A is operated momentarily, but cannot lock. Relay B pulls up and unlocks relays J, R to initiate release of the automatic switches. Fig. 3 shows an arrangement employing loop impulsing over physical and phantom trunk circuits. The dialling key K1 associated with the phantom circuit controls a relay P which shortcircuits the line condensers, and a relay Q performs a similar function at the incoming end of the trunks. A relay S2 is provided for each incoming circuit, which operates when relay B pulls up, locks in parallel with relay C, and completes the impulsing loop to the repeating valve. The circuits may be modified by providing a single repeating valve common to the three or more circuits incoming from a particular toll position.
