Title: Improvements in or relating to machines controlled by record cards, more particularly statistical machines
Filed: 1930-11-11
Abstract: 364,247. Statistical machines. STUIVENBERG, C. H., 87, Yelserstraat, Haarlem, Holland. Nov. 11, 1930, No. 33957. [Class 106 (i).] Total-taking.-In a record-card controlled statistical machine for grouped cards, the card-group change is detected and total-taking initiated by a device which compares the actual card-reading from the card following that being treated, directly with an adjustment which is effected along a path the length of which varies according to the numeral expressed by the perforation in the card being treated. Specification 322,064, [Class 106 (i), Calculating &c.], is referred to. The card 32 is read by pins 33, Fig. 2, the pin which reads the card-hole rising to arrest differentially a sector 34 (one for each column) which carries with it a rod 1 attached to a slide 3 moving along a rod 5. The card 36, immediately following card 32, is between plates 38 which are then raised so that a pin 39 passes through a card-hole, the remaining pins 39 of the column being raised. If the pin 39 reads the same hole in card 36 that pin 33 has read in cam 32 (for the same column) a bolt 28 pivoted to slide 3 remains down, resting on pin 39. When, subsequently, a shaft 12 moves to the right it projects a rod 11, resting on lever 28, through a hole 40 in plate 13. If, however, the holes read in the two cards disagree, as when the card group changes, lever 28 is raised, and rod 11 rotates bell crank 13, 15 clockwise when shaft 12 is moved. A single plate 13 coacts with the rods 11 for all the columns, so that the control may be effective over several card columns. The rocking of bell crank 13, 15 initiates a special operation such as total-taking. The differential movement of sector 34 controls adding and printing operations. In a modification, the pins 39 are omitted and a pin formed integral with each lever 28 reads the card 36 when the plates 38 are raised. In a further modification, Fig. 5, the differentially moved rod 1 has a pin 42 for reading card 36 and an arm 43 with an eye sliding on a rod 44. This rod and shaft 45 correspond to 11, 12, Figs. 1 and 2 ; rod 45 is not moved to the right but remains stationary. When plates 38 are raised, if the card hole registers with pin 42 nothing happens, but if the holes in the consecutive cards disagree, then rod 44 is raised about pivot 45 and rocks bell crank 13, 15 clockwise to initiate totaltaking.

Filed: 1921-12-21
Abstract: 173,235. Terres, E., (Assignee of Stettiner Chamotte-Fabrik Akt.-Ges. vorm. Didier). Dec. 21, 1920, [Convention date]. Producers.-Combustible gases are obtained from a fuel of small size and rich in ashes in a gas-producer which is so operated that above the air supply nozzles a porous slag structure is provided extending entirely across the fuel bed so that the air passing through this porous structure is supplied to the fuel in a finely divided and highly heated condition. This slag structure is either formed by burning out the organic matter in the fuel and allowing the slag particles to frit together or is built up from pieces of slag, the fuel being charged on to the top. The air nozzles are arranged equidistantly round the bottom of the shaft and are inclined downwardly. Steam may be introduced alone or mixed with air either into the slag structure or into the combustion zone.

Title: Improvements relating to telegraph printers
IPC: H04L15/34
Filed: 1928-11-30
Abstract: 323,098. Warburton, F. Nov. 30, 1928. Type - printing telegraphs.-In a telegraph printer actuated by combinations of signals comprising a variable number of impulses, the signals are stored by setting elements a, b in a moving member 1, 2 by mechanism 9 mounted on a movable carriage 8 so that sufficient signals can be stored for printing to take place at a rate less than the rate of reception of the smallest number of impulses comprising a signal combination. When printing from Cable Code a dash magnet 45 or a, dot magnet 46 moves, through levers 43, 42, 41, an arm 36 or an arm 39 into the path of a cross-bar 37 on a rod 32 which is reciprocated vertically by a drum cam 35 on a synchronized shaft 14. The rod is thus rotated to the left or right according to the signal received, and causes, through a fork 38, the sliding member 9 to displace a pin a or a pin b. The storage wheel 1 is rotated a distance corresponding to the number of impulses in the signal combination of the character to be printed by a toothed sector 83, as described in Specification 307,960, [Class 100 (iv), Typewriters &c.]. The storage wheel drives, through a spindle 3, reversing gearing 23, 22, 21, and a spindle 20, a side bevel 19 of a differential gear. The other side bevel 24 drives a sleeve 26 on which the carriage 8 is mounted, and the box 12 is rotated by a ratchet wheel, which is released, one tooth at a time, by a cam 17 on the shaft 14. The sliding member 9 is thus maintained in position to actuate successive pins whatever the number of impulses corresponding to the character printed. Printing of successive characters corresponding to a large or a small number of impulses results in a drift of the carriage 8 which is counteracted by rotation of the carriage moving an arm 28 over a rheostat 29 to cause appropriate acceleration or retardation of the printing-motor. According to a modification, Morse Code signals are used (Fig. 5-7, not shown).
