Title: Improvements in or relating to film type distillation apparatus
IPC: B01D3/10
Filed: 1947-11-11
Abstract: In distillation involving the flow of the distilland over an evaporation surface in the form of a film and the condensation of the vapours on an adjacent condensing surface, the distilland is repeatedly redistributed over the evaporation surface by the action of rollers which are mounted in recesses in the condensing surface in order that the latter may be positioned close to the evaporation surface.  The vapour gap between the rollers and the walls of the recesses should preferably be very nearly the same as the gap between the condensing and evaporation surfaces.  In a preferred embodiment the condensing surface is rotatable.  The still shown comprises a shell 12, an evaporation surface 33 heated by a jacket 30, and an annular condenser 60 supported by shafts 61, 62 journalled in bearings 44, 49.  The outer shell 64 of the condenser is provided with recesses 67 to receive the roller rods 68 which are in contact with the evaporation surface. These rods are resiliently supported in rings <PICT:0629513/III/1> <PICT:0629513/III/2> 69, 70 which are connected to the condenser and rotate with it. In order to ensure rotation of each rod as it moves over the evaporation surface, each rod is provided with a pinion gear 80 which meshes with ring gear 81. The unitary structure comprising the condenser and rods is rotated, through sprocket gear 102, by an electric motor (not shown).  The still is evacuated through both ports 15, and steam or a mixture of diphenyl and diphenyloxide is passed through jacket 30.  The distilland is supplied through pipe 17 to pan 84 from whence it is conducted to the rods by pipes 86.  The distillate flows from the condenser into pan 90 and then passes through pipe 92 into trough 93 from whence it is withdrawn from the still through pipe 20.  The distillation residue is withdrawn from the still through pipe 19. Specification 617,613 is referred to.

Abstract: 893,568. Twist-tubes and driving arrangements therefor. UBBELOHDE, L. Sept. 2, 1959 [Sept. 15, 1958; Sept. 24, 1958; Oct. 14, 1958; Nov. 12, 1958], No. 29995/59. Class 120(2) Yarn is false-twisted, e.g. in a crimping or curling process, by passage between the runs of a moving endless belt or through a twist-tube disposed therebetween and the runs are constrained to conform to at least an arcuate portion of the surface of the yarn or of the outer surface of the tube to ensure intimate frictional contact therewith and thereby impart a rotary movement to the yarn or tube. The belt may be flat or of oval or circular cross-section. As shown in Figs. 1 and 6, yarn bundles or tubes, as at 5, are rolled between the runs 1 and 1a of a belt passing around driven roller 2 and roller 3 (or rollers 3, 27 and 28) and between pairs or trios-of flanged, idler rollers or pulleys 4, 4a, 4b, 4c which cause the runs to converge: pairs of pulleys may be replaced by single pulleys 4, 4c, 4a &c., Fig. 1, disposed alternately on the outside of opposing belt runs. The twist tubes may comprise flat or tapered collars or discs, engageable with the edges of the belt to limit its axial movement in the direction of travel of the yarn; and/or helical threads which cause the belt to deflect the tube from the edges, Figs. 2, 2b (not shown). Each tube 35 may be loosely held at its ends within forked supports, as at 10, Fig. 5, and the ends may be supported by discs 32 or 32 and 32a freely rotatable on pivots 33, 35a. The tube may be supported and its position maintained by a current of air, produced by a flat-cone or disc mounted on the twisting tube, impinging on a separate stationary plate, Fig. 2b (not shown). In other embodiments, Figs. 7-10, 10a-d, 11, 11a (not shown) the two runs of the belt, which are otherwise liable to rub against one another in operation, are spaced further apart by rollers 4, 4a &c. than as described above and are arranged obliquely to the yarn bundles passing therebetween so that in the twisting zone the travelling bundles first touch the one run on entry and the other run on departure.

Abstract: 1,174,869. Recording colour television. COLOUR FILM SERVICES Ltd., and R. J. VENIS. 12 June, 1968 [29 June, 1967], No. 30119/67. Heading H4F. A colour television signal, e.g. of the N.T.S.C. or PAL type, is subdivided into its three primary colour component signals by a decoder 1, and each component signal is passed, via a processing amplifier 7, 8 or 9, to a corresponding C.R.T. 16, 17 or 18 which produces a corresponding component light image. The three component light images are then combined by an optical system to produce a single combined colour image which is reproduced on conventional motion picture film comprising three superimposed layers of different colour emulsions. The C.R.T.'s 16, 17, 18 may produce a monochromatic image of the respective primary colour or its complementary colour, or each C.R.T. may produce a white image which is then subjected to optical filtering to produce the desired coloured component image. The optical system shown comprises two beam splitters 39, 40, two lenses 37, 38 and a compensating block 36 to produce a combined image focused at a plane 44. A field lens 45 and the lens assembly of the camera 43 then refocus the combined image on the film, which may be moved continuously or intermittently. An alternative optical system comprises a coherent bundle of glass fibres branched to receive the separate component images and tapered to achieve the necessary reduction in image size.

Abstract: 713,112. Variable-speed. gear. CELLOPHANE SOC. ANON. Dec. 31, 1951 [March 19, 1951], No. 30472/51. Class 80 (2) [Also in Groups XVI and XXIX] Control apparatus for a machine wherein power is supplied to several driven shafts from a common driving shaft, comprises, for each driven shaft, means for varying the power supplied to said shaft, a fluid-pressure servomotor for adjusting each of said power varying means, means for individually selecting a datum pressure of the servo fluid for each servomotor so that the sevaral pressures are in the ratio of the initial power requirements of the said driven shafts, and means actuated by a progressive increase in the power requirements of all said driven shaft correspondingly to increase the datum pressure of all said pressure fluids while maintaining them in said ratio. The apparatus is shown applied to controlling the drive of spools, e.g. three, winding bands of film which are slit from a wide roll into various widths. Bach spool is driven through a friction clutch 56, 57 including a spring 55, the tension of which is adjusted by a Servo-piston 53, supplied with pressure fluid from a chamber 5 of a device D1, there being one such device for each servomotor, Each device D1 comprises a housing divided into three chambers 1, 5, 7 and a piston valve 2 controlling communication between chambers 1 and 5 chambers 5 and 7 communicating with each other through a calibrated orifice 6 and chamber 7 communicating with the atmosphere through an orifice 8. Pressure regulating valves 10. 11 supply constant high and low pressures, respectively, in a predetermined ratio to the chambers 1 and 7, the ratio being determined by simultaneous regulation of loading springs 17, 18 by a knob 24. Each valve has two opposed closure members 35, 36 controlling communication between a chamber 34 and the inlet 32 or exhaust 33, and actuated by a diaphragm 14 to maintain a constant pressure in the chamber 34. All the valves 2 are controlled by common cam 63 driven through gearing 71 by a, shaft 72 connected to one of the spool driving shafts 59, such that one complete rotation of the cam is made while the shafts 59 make the number of revolutions necessary to fill the spools. All the shafts 59 are driven from a common shaft 58, and the initial loadings of the springs 55 are determined by adjustment of the knobs 24 in accordance with the widths of band to be wound, the valves 2 being in their lowest positions. Thus the pressures in the chambers 5 will be in a certain ratio and this ratio is maintained as the valves 2 increase communication between chambers 1 and 5 to progressively increase the pressures of springs 55 and hence the power supplied to the shafts 59 as the spools increase in diameter, to thereby maintain the .tension of the bands constant, the speed of winding being decreased with growth in diameter.

Abstract: 1,160,017. Digital electric computer. RADIO CORPORATION OF AMERICA. 3 July, 1967 [5 July, 1966], No. 30549/67. Heading G4A. A multi-processor multi-programmed computer system having a plurality of sets of program execution registers for a respective plurality of programs including a user's production program and an executive program includes a program-set identifying register associated with each computer processor, controlled means responsive to availability signals from the processors and the sets of program execution registers to insert appropriate numbers in the programset identifying registers, and first gates responsive to the contents of the program-set-identifying register associated with each processor to connect the corresponding computer processor and an identified set of program execution registers. Two processors 11, 12 are described connected by buses 13, 14 to a plurality of sets of program execution registers 21, 22, 23, 24 one of the sets being assigned to the performance of executive, supervisory and input-output programs and others to user's production programs. Each processor contains a program set register PSR containing a number identifying the set of program execution registers the processor is, or will be, connected to. Each PSR is connected to a first gate 15, 16 to allow connection of the processor to the appropriate set of registers. In operation, assuming processor 1 is following a production program using the set 21 of program execution registers, the processor checks its program interrupt flags. If an interrupt is required and allowed and no interrupt lock is present status information is stored in the set 21 of registers and an interrupt request INT REQ is sent to selector 10. This responds by sending a signal S 1  and the processor issues a set interrupt pending signal INT to the one of the interrupt pending flip-flops 25 identified by the PSR, and reset in-use signal to the identified flip flop in the group 26. The processor to perform the executive program is selected, and if this is processor 1 selector 40 issues a selection signal t 1  which passes AND gate 29 enabled by the set interrupt pending flip-flop to send an EXEC SEC signal to the processor. The processor sends an end interrupt signal to selector 10 to discontinue signal S 1 . The PSR receives from selector 20 a number identifying the set of program execution registers which has an interrupt pending, e.g. set 22. The number is then applied to 1st gates 15 to correct the processor with the register 22. The interrupt pending flip-flop is reset and the information stored in register 22 required to perform the executive program is extracted and an interrupt lock flip-flop is set to prevent further interruption. The PSR then receives a new number identifying the set of executive program execution registers that will process the interrupt that was pending in the set of registers 22, e.g. 24. The processor is connected to register 24 and the appropriate in use flipflop 26 is set. The executive routine is then performed.
