Dec. 28, 1929, No. 39679. Convention date, Dec. 28, 1928. [Class 145 (ii).] A sawing-machine for trimming printers' slugs, rules, clichÚs, &c., and adapted for operating on work presented to it at two different levels, comprises two fixed tables at different levels, and one or more adjustable tables adapted to form an extension of either of the fixed tables. The fixed tables 2, 3, Fig. 1, have mounted between them the shaft of the saw 7, which projects above the table 3 sufficiently to produce the maximum depth of cut required. A cutter or router is arranged on one side of the saw for trimming the forward edges of slugs when the machine is used for mitreing. To the table 2 is connected by links 5 a table 4, which may form an extension of either of the tables 2, 3. On the side of the saw opposite to the tables 2, 3 is mounted a vertically adjustable table 6, shown in plan in Fig. 3, which is movable horizontally on the machine frame. The table 6 carries a guide-member having two faces 13, 13a for supporting the work, the face 13 being employed when work is to be cut with a bevel. The angular position of the guide-member may be adjustable. For cutting down long slugs, which would foul the housing 12 of the saw shaft, the adjustable tables are employed in the higher position.

An ignition device for a high-pressure gas discharge lamp comprises a circuit for repeatedly applying a high-frequency voltage across the lamp, which voltage is disconnected when the lamp strikes. The lamp 14 is connected to a D.C. supply 16, 17 through a relay coil 20. A high-frequency generator 10 is connected to a separate A.C. supply 3, 4 through relay contacts 5 and manually-operated spring-loaded normally open contacts 34, 35 closure of which also closes contacts 32, 33 which energize a relay coil 23 through self-holding contacts 40, 41. Another pair of contacts 42, 43 on the same relay energize a motor 24 driving a cam 26 which periodically closes a pair of contacts 29, 51 in parallel with contacts 34, 35. When the lamp strikes, contacts 5 are opened, thus disconnecting the high-frequency generator 10 from the supply. The relay 5, 20 may be replaced by a potential relay connected across the lamp electrodes or a photo-electric device on which light from the lamp is allowed to fall. A time-switch, or a further cam-operated switch geared to the motor, may be arranged to break the circuit after a given time interval or a determined number of operations.

Title: Method of synthesizing urea
IPC: C07C273/04
Filed: 1966-09-26
Abstract: Urea is obtained by a process which includes the stages of reacting a raw material gas containing hydrogen, carbon monoxide, carbon dioxide and nitrogen with water vapour in a water gas shift zone to convert the water vapour and carbon monoxide into hydrogen and carbon dioxide to form a water gas shift effuent containing hydrogen, carbon dioxide, nitrogen, and unreacted carbon monoxide and water vapour, exchanging heat from the water gas shift effluent to the urea-synthesis effluent to distil off the unreacted ammonia and carbon dioxide from the latter and separating urea from the urea synthesis effluent, thereafter compressing the water gas shift effluent to a gauge pressure of 150-400 kg/cm.2, washing the water gas shift effluent with liquid ammonia and a medium capable of dissolving ammonium carbamate in a washing zone to absorb in the liquid ammonia and the said medium the carbon dioxide contained in the water gas shift effluent thereby forming an absorbate containing the ammonia and the carbon dioxide and a gaseous effluent from the washing zone containing hydrogen and nitrogen, the composition of the absorbate being maintained at 2 to 3.6 mols. of ammonia per mol. of carbon dioxide and thereafter maintaining the absorbate under urea-synthesis conditions to react the ammonia and carbon dioxide contained therein to form the urea synthesis effluent. The medium capable of dissolving ammonium carbamate may be water, aqueous ammonia, aqueous urea or aqueous ammonium carbamate, the gaseous effluent from the washing zone may be led to an ammonia synthesis reactor and the ammonia formed in the latter may be led back to the washing zone or to the urea synthesis reactor.
