Title: Improvements in or relating to the production of ethylene
IPC: B01J23/89
Filed: 1958-09-22
Abstract: By means of a catalyst, carbon monoxide and hydrogen are converted to a gaseous hydrocarbon mixture, predominantly ethylene, at normal or superatmospheric pressure (e.g. atmos.) and 350-520 DEG  C., preferably 350-450 DEG  C., with a preferred contact time of below 5 seconds; the fluidized bed method may be used. The catalyst is a mixture of four components, each of which may contain one or more of the specified ingredients: (1) (a) ZnO, CdO, Cu or Ag, with (b) an oxide of Cr, V, Nb, Ta, Mo, W or U; (2) a Group VIII metal or compound thereof; (3) an oxide or hydroxide of Al, Si, Ti, Zr, Hf, Th, Sc, Y, or of a rare earth element; (4) a carbonate, oxide or hydroxide of an alkali metal.  Component (1) may be activated with an oxide of one or more of Mg, Zr, Hf, Th and the rare earth elements, while component (2) (which preferably constitutes not more than 10%, particularly 0.1-1% of the total catalyst weight) may be activated with one or more of Cu or Ag or oxides of Mg, Th, Mn, or the rare earths.  The catalyst is preferably supported on an inert carrier of large surface area, particularly kieselguhr, pumice, ceramic material, a synthetic or natural silicate, fuller's earth or lignite ash.  Alternatively the first or third components may serve as the carrier. Constituents specified in examples are oxides of Al, Cr, Mn, Zn and K; Cu, Ag and Co; and kieselguhr.  Prior to use the catalyst may be reduced with hydrogen, optionally after having been activated by heating in air.  Regeneration may be effected by heating in air, which may contain added nitrogen, followed by reduction.ALSO:By means of a catalyst, carbon monoxide and hydrogen are converted to a gaseous hydrocarbon mixture, predominantly ethylene, at normal or superatmospheric pressure (e.g. 20 atm.) and 350-520 DEG  C., preferably 350-450 DEG  C., with a preferred contact time of below 5 seconds; the fluidized bed method may be used.

Title: Process for the recovery of hydrocarbons by means of solid adsorptive agents, for example, active carbon and the like
IPC: C07C7/12
Filed: 1932-10-28
Abstract: In the recovery of hydrocarbons from gases, such as coal gas, which contain resinifying constituents such as diolefines, the proportion of adsorbent used is less than twice the amount of hydrocarbons recoverable per day.  Deposition of resinous polymerization products on the adsorbent is thus minimized. Preferably short regenerative periods of about half an hour are employed.

Abstract: 1,096,840. Magnetic storage apparatus. NATIONAL CASH REGISTER CO. July 8, 1966 [Aug. 6, 1965], No. 30799/66. Heading H3B. In a rod memory array insulated conductive wire is woven perpendicular to the axes of the magnetic rods so that the wire passes by opposite sides of adjacent rods to produce a plurality of half-turn solenoids each coupled to a respective one of the rods. A plate 10, Fig. 1, provided with apertures 10a is first positioned over dummy rods 15a on a support 15 which rods protrude through the apertures 10a to act as mandrels about which the solenoid weaving pattern 18 is formed. After the solenoids have been formed the pins 15a are formed and the magnetic rods 12 comprising an inner conductive substrate on which is deposited a thin bi-stable magnetic film, Fig. 2 (not shown), are inserted in their place. In the weaving pattern of Fig. 1 of a particular row or column a conductive wire starts at a guide pin 19, is woven back and forth between the pins 15a until the end of the row or column is reached and is then brought around the last pin and woven back along the row or column in the reverse direction. Additional solenoid turns to the single turn solenoids of Fig. 1 and Fig. 3 (not shown) may be provided by repeating the weaving for each row and/or column as desired and connecting the weavings for respective rows and/or columns in series, Fig. 4 (not shown). Additional solenoid windings for a row or column may be provided by two separate weavings, each weaving providing a one-turn solenoid at each rod position, Fig. 6 (not shown). In the digit plane of Fig. 7 (not shown), a single unbroken wire is used throughout the matrix to form half-turn solenoids which are connected in series and in Fig. 5 (not shown) a two-turn solenoid is provided at each rod position in the matrix by forming a double weaving in each row before proceeding to the next row. The digit plane weave may be divided into two like weaving patterns, Figs. 9, 10, for use in obtaining common mode rejection by connection to a sense amplifier transformer. The weaving may also be employed in a three-dimensional rod matrix, Fig. 11 (not shown), in which a plurality of plates 10 are stacked together in spaced relation and each of the magnetic rods is of sufficient length to pass the aligned apertures 10a in all of the plates.
