Title: Improvements in or relating to filters for separating finely divided solid material
IPC: B01D46/24
Filed: 1950-09-19
Abstract: 682,217. Filtering gases. HERSEY, H. J. Sept..19, 1950. No. 22956/50. Class 8 (ii). In a dust filter comprising a chamber 10 having a portion 12 to which the separated dust particles may gravitate and a porous filter medium 14 suspended within the chamber and defining a subchamber, dust-laden gas being directed into the chamber 10 under pressure greater than that existing in the sub-chamber to cause the gas to pass through the filter medium, a cleaning device is located on the low pressure side of the filter medium and means are provided on the high pressure side for receiving the solids dislodged by the cleaning device and conducting them to the portion 12. The filter medium 14 is supported by a foraminous, relatively rigid support such as a wire screen reinforcing frame 16. The filter medium cleaning device consists of a blow-tube 18 housed between the support 16 and the filter medium 14, the tube being attached by hollow arms 120, 126 to a hollow shaft 40, which is rotated from a motor M which also drives a blower 84 that supplies air to the shaft 40 and hence to the blow-tube 18. Attached to the shaft 40 is a frame 132 carrying a channel-shaped receiver 142, the open side of the channel being opposite that part of the filter medium 14 which is in contact with the blow-tube 18. Dust-laden gas is introduced into the chamber 10 from an inlet at the upper end thereof, passes through the filter medium 14 into the sub-chamber and upwardly to an outlet. Dust particles deposited on the filter medium 14 are dislodged by the jet of air from the blow-tube 18 into the receiver 142, from which they gravitate to the portion 12. Portions, at least, of the invention may be adapted to a filter medium of flat or other shape, and to filters where the dust-laden gas is supplied under super-atmospheric pressure and the cleaned gas allowed to escape directly from the surface of the filter medium to atmosphere.

Patent GB-424281-A (GB)
Title: Process for the manufacture of sodium dichromate
Filed: 1933-08-18
Abstract: Sodium dichromate is obtained by reacting carbon dioxide under pressure on sodium monochromate solution technically free from calcium compounds at a temperature exceeding 50 DEG  C., but not in general above 100 DEG  C.  A partial pressure of carbon dioxide of 6--8 atmos. is particularly suitable, a lower limit of 2 atmos. being specified.  In a preferred embodiment of the process, the solution is cooled under pressure after considerable conversion of the reaction solution, and the well defined crystalline sodium bicarbonate filtered off after release of the pressure.  The solution is evaporated, and while hot, again treated with carbon dioxide under the conditions detailed above.  Sodium bicarbonate filters well from the concentrated solution.  The Specification as open to inspection under Sect. 91 comprises also the treatment of the solution with carbon dioxide, the pressure of which rises from 2--3 to 6--8 atmos., while the temperature of the solution falls from 60--80 to 25 DEG  C. The process may also be effected on the countercurrent principle, so that gases nearly exhausted of carbon dioxide act on the hot monochromate solution, while the most converted liquor is acted upon at 20--30 DEG  C. by gases poor in carbon dioxide.  Technical gas mixtures, such as lime kiln gases, may be used as the source of carbon dioxide.  Reducing gases such as sulphur dioxide and hydrogen sulphide, if present, are previously removed.  The conversion of potassium dichromate is disclosed.  In this case, potassium dichromate separates in solid form, while potassium bicarbonate remains in solution.  This subject-matter does not appear in the Specification as accepted.

Abstract: 640,810. Hooks. VICKERS-ARMSTRONGS, Ltd., and FIRMAN, R. A. Sept. 2, 1948, No. 23152. Drawings to Specification. [Class 89 (ii) [Also in Group XXI] A releasable attachment described in Specification 572,809 has a case comprising two mating portions enclosing the upper part of load-bearing hooks, the toggle-actuated locking mechanism and the load-release device. The mating portions have inwardly directed bosses forming a journal for the hooks and drilled to receive a shearpin. Shackle links carried on the pin are connected at their upper ends, e.g., by a tension bolt so that the attachment may be suspended from a lifting gear or the like. By this arrangement the forces due to a load held by the hooks are transmitted through the bosses and shear-pin to the shackle links, the case and its contents floating on the pin.
Patent GB-619846-A (GB)
Title: Improvements in and relating to signal transmission systems employing radio links
IPC: H04B7/155
Filed: 1946-04-15
Abstract: 619,846. Radio signalling. GENERAL ELECTRIC CO., Ltd., and ESPLEY, D. C. April 15, 1946, No. 23436/47. Divided out of 619,772. Drawings to Specification. [Class 40 (v)] In a radio link repeating system of the general kind described in Specification 619,772, one or more of the repeating or receiving stations is or are arranged to invert the frequencies of the derived signal band before amplification, whilst others amplify the band in its uninverted form. The inverted and the uninverted versions of the signal preferably occupy identical frequency ranges, so that identical amplifiers can be used throughout the system. That part of the distortion of an amplifier which is a function of frequency is compensated by using inverted and uninverted signal bands at alternate stations. The derived signal band may be a lower sideband resulting from modulating the original signal on a sub-carrier, or an upper side-band, or a band comprising the whole of one sideband and a portion of the other. Transmission from station to station may be effected by modulation of the derived band on a shortwave carrier and radiation of one side band. If the lower side-band is radiated, it represents the derived band in inverted frequency order, and by mixing it at the receiving or repeating station with a local short-wave, this inverted band may be reduced in frequency so that it lies within the desired frequency limits. The Provisional Specification of 449,322 also is referred to.

Abstract: 1,219,968. Separating gaseous hydrocarbon mixtures by adsorption. SCHWERMASCHINENBAU "KARL LIEBNECHT" MAGDEBURG VEB. 17 May, 1968, No. 23554/68. Heading B1L. [Also in Division C5] A gaseous feed of a hydrocarbon mixture to be separated is passed to column 1 by line 12. In column 1, adsorbent, e.g. synthetic zeolite, is in continuous downward movement in counter-current to the feed which rises together with flushing gas through adsorption zone 2 where particular fractions of the gas mixture are selectively adsorbed the residual stream leaving through outlet 14. As the loaded adsorbent passes down the column, it is first flushed with a gas stream which enters at the base of zone 3, before passing through downcomer 11 to desorption zone 4. In this zone, the sorbate is desorbed by countercurrent contact with e.g. a low molecular weight paraffin or a polar compound, the desorbate stream leaving by line 13. The desorbed asdorbent then passes to zone 5 where it is entrained by carrier gas and passed by pneumatic lift 6 to the head of the column for recirculation, carrier gas leaving by line 18. Zones 2, 3 and 4 all contain a plurality of cross-flow trays.

The strain constant A k  is defined by the equation A R  = K 1 . S 1  where K 1  is the compression component of the force exerted by the members on the foils and is expressed by the ratio f 1 /F, where f 1  is the total thickness of the foils in the final laminate and F is the total thickness of the foils prior to lamination; and S 1  is the frictional component of the force exerted by the members on the foils and is expressed by the ratio a/(b.Á) where a = f-f 1 , b is the distance in the direction of travel of the foils over which lamination is effected and Á is the coefficient of friction of PTFE. In a preferred embodiment a plurality of parallel elongate electrical conductors are interposed between two by the method of the invention to form a signal ribbon cable, the conductors being in the form of wires. Alternatively, glass fibres, heating elements, foils, nets, magnetic elements or tubes may be bonded between two foils of PTFE.
