Title: A process for the production of calcium formate
IPC: C07C51/10
Filed: 1933-08-04
Abstract: In the production of calcium formate by the action of carbon monoxide on suspensions of lime in presence of alkali formate, the speed of reaction is increased by adding more than 30 parts of alkali formate to each 100 parts of lime.  A table is given showing the effect of additions of varying quantities of alkali formates to a 6 per cent suspension of lime.  The process may be carried out in presence of a saturated solution of calcium formate so that the calcium formate is precipitated as it is formed.  The alkali formate required may be produced in situ by treating a suspension of lime in caustic soda solution.  Specification 363,788 is referred to.

Title: Improvements in and relating to grid controlled rectifier circuit arrangements
Inventor: SMART DAVID LORIMER
IPC: H02H7/127
Filed: 1949-08-24
Abstract: 674,985. Rectifying. ENGLISH ELECTRIC CO., Ltd. Aug. 18, 1950 [Aug. 24, 1949], No. 22040/49. Class 38 (ii). A multi-phase grid controlled rectifier arrangement has each control grid supplied through an insulating transformer, fault-sensitive switching means being provided, effective on the occurrence of a fault, to open the primary circuit of each transformer so as to achieve arc suppression by interrupting the supply of energy to the transformer, the insulating transformer 1, Fig. 1, supplying, by means of its secondary windings 2, 6 respectively the excitation circuit and grid circuit of a rectifying valve. A condenser 7 is included in the grid circuit so that when the supply is removed from the primary winding of the transformer the condenser will remain charged and provide a negative grid bias for as long as the excitation current persists thus preventing further conduction by the anode. The multiphase rectifier arrangement shown in Fig. 3 has a separate insulating transformer 16-21 for each of the rectifiers 10-15 respectively, the transformers being fed over a number of relay contacts 23-25. When a fault occurs contacts 39 of a high-speed fault detecting relay are closed and a thyratron valve 31 begins to conduct thus allowing a condenser 38, which charges during the non-conducting period of the valve 31, to discharge through the operating coils of the relays 27-29 so opening contacts 23-25 respectively to remove the supply to the insulating transformers 16-21, thus suppressing the arc in the rectifier 10-15. A relay 40, which does not cause operation of the relays 27-29 is arranged to operate, when the valve 31 conducts, to initiate a complete cycle of a motor driven cam-shaft which resets the relay contacts 23-25 and operates contacts 41-45 in sequence for restarting the rectifiers. The cam-shaft may be arranged to be stopped at any intermediate position to provide reduced output voltages. The output voltages may be controlled by phase control on the input to the insulating transformers.

Title: Improvements in or relating to a methed for photochemical reaction of organlc compounds
IPC: H01J61/58
Filed: 1953-08-10
Abstract: Photochemical reactions of organic compounds are effected by exposing a reactant stream to light radiation from a contracted electric arc, the reactant stream passing through a flow path which lies at least in part within an outer annular portion of the arc but which, along at least a major portion of its length, does not penetrate into a cylindrical region coaxial with the arc and having a crosssectional area 75 per cent of that of the <PICT:0763446/III/1> <PICT:0763446/III/2> <PICT:0763446/III/3> arc.  In the apparatus of Fig. 1, a contracted arc is formed in a glass tube 11 between pools of mercury 17, 18 in which are immersed tungsten electrodes 13a, 14; the reactants flow through U-shaped quartz reaction tube 19.  In modifications of this apparatus, Figs. 2-4 (not shown), the tube 19 is replaced by concentric glass and quartz tubes, by a quartz tubular coil, or by a plurality of parallel reaction tubes.  In a further modification, a glass jacket having an inlet and outlet surrounds the tube 11 to provide an additional flow path for the reactants. Fig. 5 shows apparatus comprising a housing 70 with a plurality of anodes 71 and a pool of mercury 75 serving as a common cathode. Alternating potential is applied to the anodes to cause them to discharge and form contracted arcs in sequence.  The reactants flow in parallel streams through tubes 78.  A modification, Fig. 6 (not shown), includes a plurality of cathodes and anodes, so arranged that each contracted arc is associated with a U-shaped reaction tube.  The device of Fig. 7 comprises a helical quartz reaction coil 101 arranged in glass vessel 100; the arc is formed between barium-strontium oxide coated electrodes 105, 106; a drop of mercury 120 provides vapours for the arc.  In the devices described the housing contains a suitable inert gas and the pressure is adjusted to provide the contracted arc.  Cadmium or sodium may replace the mercury.  Reactions referred to are the condensation of the n-butane to form an octane or dodecane, and reaction of butane with propane or propylene to form heptane; mercury, cadmium, or zinc may be present as a sensitizing agent. In the sulphohalogenation of a paraffinic hydrocarbon, e.g. n-heptane, with sulphur dioxide and halogen, the halogen acts as a sensitizer.  Carbonyl compounds such as acetone may also be used as sensitizers.  Reaction conditions may be a temperature of 80 DEG -650 DEG F. and a pressure of atmospheric or above.

Title: Process for effecting sublimation in a fluidised bed sublimer
IPC: B01D7/00
Filed: 1956-07-17
Abstract: <PICT:0821643/III/1> Material to be sublimed is added to a fluidised bed of inert solid above which a reduced pressure is maintained by a vacuum pump; vapours of the material leave the bed with the fluidizing gas, and inert solid is continuously or intermittently removed, purified, and recycled to the bed.  Reduction of the grain size of the inert solid allows the gas throughout to be increased. As shown, raw material is introduced at A into fluidized bed sublimer B and sublimate collects in condenser C; vacuum is maintained by pump E which draws gas to the fluidized bed through heater H; inert solid is withdrawn at J, purified at K, and recirculated.  An example describes the purification of anthraquinone using sand as the inert solid and nitrogen as the gas.ALSO:Anthraquinone is purified by a sublimation process which comprises adding the crude material to a heated fluidized bed of sand above which a reduced pressure is maintained by a vacuum pump; anthraquinone vapours leave the bed together with the nitrogen fluidizing gas and are condensed.  The sand is continuously or intermittently removed, purified, and recycled to the bed.

[Also in Division G1] The description is substantially identical with that appearing in Specification 945,593, but the claims relate to the feature of including in a photo-electric exposure timer, Fig. 12 (not shown), a resistor-capacitor interpolating circuit for the purpose of converting a step-bystep increasing potential, which is generated by a summing capacitor in response to pulses from a photo-electric cell, into a continuously increasing potential which permits the exposure time to be controlled continuously and not in discrete steps.
