Patent GB-727318-A (GB)
Title: Manufacture of an unsaturated aldehyde
Inventor: HADLEY DAVID JAMES
Filed: 1951-08-25
Abstract: A process for the manufacture of acrolein by passing propylene with gases containing molecular oxygen at elevated temperatures in the presence of elementary selenium in the reaction zone over a contact material comprising initially copper oxide distributed upon activated alumina comprises preheating the contact material at temperatures between 750 DEG  and 1000 DEG  C., passing the gaseous reaction mixture over the contact material at a temperature between 210 DEG and 350 DEG  C. and providing for the presence in the mixture of reacting gases of selenium vapour in an amount within the range of 0.008 to 0.12 milligram per litre of gas mixture. Two reactors in series may be used, the first containing solid contact material which has been previously heat-treated, the second reactor containing solid contact material previously heat-treated at a lower temperature which is maintained at an elevated temperature whilst the first reactor is kept at a slightly higher temperature than the second reactor. Alternatively a mixture of the more and less active contact materials in a single reactor may be employed.  A high selenium content may be employed initially in the gaseous mixture to bring the selenium content of the contact material to the normal equilibrium content. Selenium is recovered by cooling the mixture issuing from the reaction zone and acrolein is recovered by scrubbing the reaction products with water followed by fractional distillation.  Residual volatile selenium compounds may be recovered by adsorption on active charcoal.  Part only of the aldehyde may be removed from the reacted mixture and the remainder of the gas mixture may be recycled with fresh olefine, oxygen containing gases and selenium.  In examples: acrolein is prepared by passing propylene mixed with air over heated selenium and a contact material prepared by evaporating a mixture of copper nitrate solution and activated alumina to dryness and heating, a high selenium content being first employed in the reactant gases which is subsequently reduced to within the specified range (1); a similar process is carried out using a tubular steel reactor (2); and a similar process is carried out using a contactmaterial which has been heat-treated at a higher temperature than that employed in (1). Specification 706,552 is referred to.

Title: A cartridge magazine for a gun
IPC: F41A9/64
Filed: 1965-05-12
Abstract: 1,095,597. Cartridge magazines. BOFORS A.B. May 12, 1965 [May 13, 1964], No. 20080/65. Heading F3C. A cartridge magazine for a gun comprises one or more compartments for cartridges to be located in a vertical row one above the other with their longitudinal axes extending substantially horizontally, each compartment having an opening at its lower end through which cartridges are fed by gravity to a conveying path 19 extending below each compartment in a substantially horizontal direction. A cartridge feed-control mechanism is associated with at least one of the compartments and includes a retaining means 6 which comprises two arms 8 secured to and pivotable with a shaft, the arms being urged into the path of a cartridge 5a by a torain spring 9 (Figs. 1, 2). At the outer ends of the arms 8 are cams 33 which co-operate with abutments 34 of further arms 30, the cam-abutment co-operation together with the inner end of the arm 30 engaging the cartridge 5a in the retained position supports a further cartridge 5c in the compartment. The shaft 7 is further provided with a retaining member 10 secured thereto and co-operating with a dent 13 of a second, pivoted retaining member 12. A pin 15 works in a slot 17 of a spring-loaded, pivoted linkage 16, 22, 29, 30 which is actuated by a feeler 18. A cartridge falling on the feeler 18 depresses it to actuate the linkage and lock the retaining members 10, 12 together to secure the arms 8, 30 in their cartridge retaining position until the cartridge moves away from the feeler. Cartridges moving from an adjacent compartment under the compartment described above causes the feeler 18 to oscillate due to the cylindrical nature of the cartridge. This oscillation, however, is taken up by the slot 17 in the linkage and not until the space below the compartment is entirely free from a cartridge or a portion thereof can a cartridge be fed from the compartment by the raising of feeler 18 to its fully spring-loaded free position with the subsequent freeing of the retaining members 10, 12 and arms 8, 30.

Abstract: 1513754 Data storage systems CONTINENTAL GROUP Inc 14 May 1975 [15 May 1974] 20229/75 Heading H3H A data storage system includes a data acquisition system, Figure 2, and a data translating system Figure 3, the data acquisition system receiving digital or analogue data, translating it if necessary at 110, to digital form, the translated digital data being stored at 150 and data acquisition halted when the store 150 is full; and the data translating system receiving the stored digital data from the data acquisition system and storing it at 250, the data reception being halted when the store 250, which is of equal capacity to the store 150, is full, the digital data from the store 250 being translated at 210 into analogue form for application to a display device (not shown). The data acquisition system may be a battery-powered portable unit which is substituted for a can of a plurality of such cans which are passing through a can oven, a thermocouple 30 attached to an adjacent can providing analogue temperature data to the unit. An internal clock generator 122 controls the sampling rate of the analogue-to-digital converter 110 and the transmission of the data from the converter 110 to the store 150 via a register 140. A pilot word, which is a word not corresponding to  any of the normal outputs of the converter 110, precedes the data and, when the store 150 is full, emerges therefrom into a register 160 and thereby disables the clock generator 122 to halt the data acquisition, and places the unit in a standby mode. When the unit emerges from the oven it is connected to the data translating system via lines 132, 162. Under the control of clock pulses from an internal lock generator 222 of the data translating system, the data from the data acquisition system is transferred to the store 250 of the data translating system, the pilot word emerging into a register 260 form the store 250 when the latter is full to disable the clock generator 222 to halt the data transfer. The emergence of the pilot word also causes the store 250 to be placed in a recirculating configuration. To display the data, the clock generator 222 is again actuated; the end of the data display is identified by the pilot word again appearing in the register 260 which again disables the clock generator 222.

Abstract: 516,800. Route setting apparatus. STANDARD TELEPHONES & CABLES, Ltd., GRIFFITHS, J. B., and BROWN, A. July 8, 1938, No. 20287. Addition to 496,495. [Class 105] The route setting apparatus described in the parent Specification is modified so as to reduce the number of contacts of certain relays and to dispense with certain other relays. The Figure corresponds to Fig. 6 of the parent Specification but it will be seen that the contacts 2RC, 3RC, 4RC are situated on the negative common side of the clutch magnet 1R and the same contacts can serve for other clutch magnets. The proving relays such as IPR are made slow acting and therefore do not drop while a conflicting sequence switch is passing through a conflicting position. For instance if after sequence switch 1 has been set the sequence switch 2 ,is operated (to set, up a non-conflicting route) the sequence. switch 2 will pass through positions 3 and 4 which are allotted to routes conflicting with those of .sequence switch 1 but the relay 1PR will not drop since its circuit is only briefly opened during the passage of the sequence switch 2. Where several successive positions on sequence switch 2 are allotted to routes conflicting with those of sequence switch 1 the cam 2D of sequence switch 2 may be arranged to give brief contact reclosure at intervening fractional positions 3¢, 4¢ so that the relay IPR is re-energized before it has dropped. By this arrangement the relays such as 2RF of the parent Specification can be omitted.
