Title: Process and apparatus for the conversion of liquefied gases into gas at atmospheric temperature and at any desired pressure
IPC: F17C9/02
Filed: 1931-04-23
Abstract: 375,479. Revaporizing liquefied gases. MURRAY, K. S. and BRITISH OXYGEN CO., Ltd., Angel Road, Upper Edmonton, London April 23, 1931, No. 12053. [Classes 8 (ii) and 102 (i).] Gas is charged into steel cylinders &c. by vaporizing liquefied gas in coils &c. 4, 5, Fig. 1, and utilizing the resultant gas in a motor 7 which drives a pump 3 drawing liquefied gas from a supply and forcing it into the vaporizer, the gas from the motor or an associated part being delivered to the containers. Gas is generated at a higher pressure in the coil 5 and is delivered by a valve 15 to the space above the piston 8 ; during the downstroke the valve 15 closes and at the end of the stroke valve 11 allows the gas to pass to the underside of the piston and a valved delivery pipe 12 ; a branch 12a delivers gas to a piston 10 effecting the upstroke. In a modification, the piston 10 is omitted, the upper side only of the piston 8 having a'rod connected by a crosshead to the pump piston; the difference of working areas of its two faces allows the piston to be returned when the pressures on its two faces are equalized. In a third form the piston 8 is acted upon by liquid which is supplied to and 'withdrawn from its two sides from vessels subject to the pressure of the gas supplied through cam-actuated valves which at intervals allow the pressures on the unequal working faces of the piston to be equalized. Fig. 4 shows apparatus in which the pump is operated by a plunger 8 raised by liquid from a vessel 24 under the gas pressure and returned by gravity. The valves controlling,..the gas supply are operated by a lever 52 and a slider 54,-the gas discharged from the vessel 24 passing away through valve 51 and pipe 55 to the storage vessels.

Abstract: 625,603. Stud-and-socket fastenings. HANNAM, W. A., HAWKINS, H. G., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. May 5, 1947, Nos. 12065/47 and 11614/48. [Class 44] [Also in Group XXIX] A method of securing a rigid fitting to the flexible walls of a liquid container, particularly those suitable for aircraft, comprises securing the fitting 1 to the centre of a flexible plate 6 which in turn is secured to the wall 2 of the tank by a number of male members 8 of press fastenings engaging the corresponding female members 7 of the fastenings which are spaced around the periphery of the plate 6. The male members are secured between flexible plates 9, 10 which are sewn together and the composite plate is stuck to the tank wall. In the event of a crash, the stitching between the plates 9, 10 breaks first so freeing the fitting without however puncturing the wall 2. In a modification, the female members of the fastenings are forced over bulbous projections of the resilient male members of the fastenings which are secured to the wall by flanged portions. The bulbous portions may be recessed in order that they may yield more easily on passing through the female members. In a crash, the fastenings break so freeing the fitting without damage to the wall 2.

Title: Improvements in or relating to ultra-high frequency band separating filters
IPC: H01P1/213
Filed: 1957-04-18
Abstract: 820,632. Waveguide directional couplers. MARIE, G. R. P. April 18, 1957 [April 28, 1956], No. 12807/57. Class 40 (8). A filter for separating two frequency bands comprises a waveguide directional coupler having a number of coupling waveguides whose cut-off frequency lies between the inner limits of the two bands to be separated. As shown in Fig. 4, a square-section waveguide 10 along which energy of both bands propagates is coupled by means of two series 17, 18 of waveguide sections to a pair of secondary waveguides 11, 12 of rectangular section. Only the energy in the upper frequency band is transferred to the secondary guides 11, 12 since the coupling guides are beyond cut-off for the lower band of frequencies. The secondary guides are coupled by an E-plane T-junction to a common output 14. By providing two pairs of secondary guides coupled to all four sides of the main guide 10 by four series of coupling guides, band separation can be achieved independently for two systems of waves polarized at rightangles in the main guide (Fig. 5, not shown). A simplification may be obtained by using one of the electrically identical halves of the construction of Fig. 4 obtained by bisection in the plane 20, 21, 22. In such a modification, the main guide 1, Figs. 1, 2, is of rectangular section and of the same dimensions as the single secondary guide 2. The coupling guides 4, 5 all have the same cut-off frequency, those near the centre of the coupling being dimensioned for a higher characteristic impedance than those near the extremities. The guides are spaced at intervals of one quarter wavelength at the upper mid-band frequency and are an odd number of quarter wavelengths long at this frequency. Concentration of the energy in the upper band near the ends of the coupling guides may be obtained by means of dielectric slabs 6, 7 having the profile and cross-section shown. This construction of coupler is applicable to all the modifications.

Title: Improvements in or relating to the continuous refining of fatty oils
IPC: C11B3/06
Filed: 1952-05-21
Abstract: <PICT:0705041/III/1> In the continuous refining of fatty oils with alkali, the alkali treatment being carried out in two stages and the soap formed in the first stage being separated from the oil before it enters the second stage, steam is blown through the oil during the second stage.  The oil is preferably heated to about 100 DEG C. prior to the steam blowing.  The oil may be finally washed, dried, bleached and deodorized by blowing with steam under vacuum.  In a suitable plant the oil fed to a mixer 2 is neutralized by lye supplied through a pipe 3, and then led to a closed centrifugal separator 5 for removal of the soap formed.  The oil is then fed to a mixer 8 and, by supplying steam through a pipe 9, is heated to a temperature of about 100 DEG C.  Lye is added to the oil in the mixer 8 from a pipe 10 and the oil then passes to a reaction vessel 12 through which steam is blown from a pipe 13.  Dilution of the lye with condensate in the vessel 12 is avoided by heating the oil to about 100 DEG C., and practically all the steam supplied thereto flows therethrough to an outlet 14, producing an intimate mixing of the oil and lye.  The oil overflows through a pipe 15 to an open-type centrifugal separator 16 for removal of the freshly formed soap and is discharged through a pipe 18 for subsequent washing, drying, bleaching and deodorizing. Soda lye, potash lye, soda, water glass or mixtures thereof may be used for the second stage of the alkali treatment.  The oils specified comprise rape oil, soya-bean oil and fish oil.
