Title: A process and apparatus for the continuous distillation and rectification of liquids
IPC: B01D3/08
Filed: 1938-06-20
Abstract: 516,125. Fractional distillation film evaporators. SOC. GENERALE DE FOURS A COKE SYSTEMES LECOCQ SOC. ANON. June 20, 1938, Nos. 18270, 18271 and 18272. Convention dates, June 21, 1937, July 10, 1937 and Oct. 6, 1937. [Class 32] Liquids are distilled and rectified in a series of horizontally rotating cylindrical chambers, each containing a series of concentric cylindrical or spiral surfaces over which the liquid progresses from the centre outwards, the surfaces being provided with vanes or'scoop devices which spread the liquid thereover. A rotary drum comprising a series of chambers 2, 3, 4, is mounted on a shaft 5 carrying hollow members 27, 41 through which the liquid and condensate are delivered and from which vapours are removed respectively, the chambers being provided with a series of concentric cylinders 13, 14 or alternatively a spiraloidal, receptacle. The rotary drum is enclosed in a lagged enclosure A provided with extensions 1 and the enclosure and extensions are filled with a heat transmitting liquid of high boiling point which is heated to the temperature required for the distillation by steam coils 8. The exterior walls of the drum are provided with buckets 9 having apertures 10 to discharge the heating liquid over the walls of the drum. Channels 11 co-operating with extensions on the drum prevent mixing of the heating liquid in each compartment while, double walled dividing plates 12 prevent transmission of heat from one chamber to another. The cylinders 13, 14 are mounted alternately on opposite sides of the chambers and are provided at their free ends with apertured flanges for the discharge of liquid. The liquid is spread on the cylinders by apertured scoops 16, Fig. 3 and 5, comprising a curved plate 17 enclosing a space divided by a plate 18, the liquid entering 'the space by apertures 19 and on rotation of the drum being sprayed out again through perforation 21 on to the outer wall of next cylinder and through perforation 20 on to the inner wall of the cylinder carrying the scoop. The liquid to be distilled enters through tube 24 and flows into chamber 25 where it mixes with condensate returned through pipe 26 from the condensers, and from which it is delivered to the distilling chamber by scoops 30, Fig. 2, delivering to the member 27 comprising an annular space formed by concentric tubes 5a, 5b and divided into four conduits 28, 29 by helicoidal ribs 5c. The distilled vapours pass off through conduits 28, chamber 25, and pipe 26. Residual liquid from chamber 2 is passed to the next chamber 3 by means of a spiral conduit 33, Fig. 4, located between the double dividing walls 12. In a modification, Fig. 11, 12 the spreading cylinders are replaced by a receptacle comprising two cheeks 54 connected by a spirally wound wall 55 provided with vanes 56 for the distribution of the liquid. The spreading cylinder may have polygonal instead of curved walls.

Title: Improvements in or relating to current controlling devices
IPC: H01L45/00
Filed: 1969-04-10
Abstract: 1,260,191. Solid-state switching elements. ENERGY CONVERSION DEVICES Inc. 10 April, 1969 [11 April, 1968], No. 18342/69. Heading H1K. A symmetrical solid-state switching element has a semi-conductor mass containing boron with one or more of scandium, yttrium, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium. Silicon and/or carbon may also be present. The boron content should be greater than 50 wt. per cent and preferably should be at least 75 wt. per cent. The element switches from an initial very high resistance state to a low resistance state when a threshold voltage is exceeded and reverts to the high resistance state only when the current through the element is made less than a holding value. The semi-conductor may be prepared by mixing the particulate elements and fusing them together either in an arc furnace or by the use of an electron beam. Fragments of the fused material may be provided with ohmic contacts or the material may be used as a source for evaporation or sputtering. Alternatively the elements may be evaporated or sputtered on to a substrate without initial fusion. In a further variant, the fused material is ground to a powder which may be placed directly between electrodes, which may be compacted and placed between electrodes, or which may be made into a paint and applied to electrodes. Depending on the composition and/or method of preparation the material may be amorphous or crystalline. Both forms are considered to have a polymeric structure. The electrodes are of tantalum, niobium, tungsten, molybdenum, or graphite.

Title: Improvements in or relating to lens systems
IPC: G02B7/00
Filed: 1942-12-28
Abstract: 562,438. Lens systems. KODAK, Ltd. Dec. 28, 1942, No. 18425. Convention date, Feb. 9. [Classes 97 (i) and 98 (i)] In a lens system, flare-producing reflections. from refracting surfaces forming an air space are reduced by a zero power light filter movable into and out of said air space. The filter may be inserted only when the system is being used at low apertures ; and its mount may be coupled with the diaphragm-setting means so that the filter is inserted automatically at a certain stage in the reduction of the aperture. In one form, for a photographic camera, a slide having a large unobstructed aperture and also a small aperture covered by a neutral density filter is displaceable across the lens axis independently of the diaphragm - setting apparatus. In another, a similar slide 37, Fig. 4, serving also as a diaphragm regulator, has a series of diaphragm apertures 31, 32 &c., of which those smaller than a certain value, are all covered by a neutral density filter 36 ; and in this form the adjacent unobstructed aperture 33 and obstructed aperture 34 are of the same size, so that in changing from one to the other the light diminution is effected solely by the filter 36. In a form of the automatic kind, the diaphragm is set by turning a ring 41, Fig. 6, bearing an aperture index 40 and a cam 42 which, as the aperture is changed from F/5.6 to F/8 rocks a pivoted mount 44 so as to move a filter 46 carried therein into operative position 44<1>. Preferably, in this form also, the size of the aperture is not changed as the index 40 passes from F/5.6 to F/8, and this may be provided for by employing a modified adjusting means in which the diaphragm is set by a surrounding toothed ring operated by a mutilated gear on a shaft carrying also a second mutilated gear which is adapted, when the gap in the firstmentioned gear encounters the diaphragmoperating ring, to operate through a toothed wheel the pivoted mount of the filter so as to bring the filter into the optical axis, whereafter the second-mentioned gear disengages, and the first-mentioned gear resumes its drive on the diaphragm-operating ring.

A machine tool for chamfering the ends or edges of gear teeth comprises a work spindle 16 arranged for reciprocation towards and away from an adjacent cutter spindle assembly 31 and for intermittent or continuous rotation in timed relation with its reciprocatory movement. The cutter spindle assembly 31 is angularly adjustable on a cutter head 20 which is horizontally adjustable on a slideway on a cutter beam member 11 which is itself vertically adjustable on a column 12, the latter in turn being adjustable on a slideway 14 towards the work spindle 16. Reciprocation of the work spindle 16 is effected by a rotary cam (93) and follower (91), (Figs. 4, 5, not shown) serving to oscillate a rocker shaft (71) having a rocker arm (70) engaging the spindle 16 while a Geneva mechanism (101, 102), driven from the cam-shaft (94) is connected through spur-type change gearing (108) either to a worm and worm-wheel drive (105, 60, Figs. 3 and 6, not shown) or to a bevel gear drive (203, 209, Figs. 10, 11, not shown) for rotating the spindle 16 intermittently in timed relation to retraction of the work spindle. In the case in which the spindle 16 is driven by bevel gearing a cam operated brake (Figs. 11, 13, 14, not shown) comprising two spring loaded brake shoes (230, 231) surrounding a brake surface on the periphery of one of the gears (209) holds the spindle against rotation except during indexing. If the work spindle 16 is to be rotated continuously the Geneva mechanism is replaced by direct gearing of required ratio. Two cutter spindle assemblies may be mounted on the cutter beam 11 the drive shaft 24 extending (Fig. 9, not shown) through the first to a female splined terminal portion from which drive may be taken to the second assembly. The work spindle 16 may be mounted for rotation and reciprocation in plain bush bearings or in linear and rotary ball bearings (220, 222, Fig. 12, not shown).

Abstract: 710,363. Automatic temperature control systems. DUNLOP RUBBER CO., Ltd. July 4, 1952 [Aug. 4, 1951], No. 18517/51. Class 38(4) To prevent undue temperature rise of aircraft de-icing equipment when icing conditions disappear, an electric heating element 1, the resistance of which varies with temperature, forms with resistances 3, 4, '5 a bridge network 2 which is supplied from a D.C, or A.C. source e, f through contacts of a relay 6. Relay 6 is momentarily operated at predetermined intervals by cam-operated contacts 8 and if element 1 is below a temperature determined by the setting of resistance 5, unbalanc of bridge 2 energizes a relay 10 to maintain relay 6 energized until element 1 reaches the predetermined temperature to balance the bridge. Thereafter the system functions periodically to restore element 1 to the predetermined temperature. A rectifier 11, necessary when the supply is A.C., also prevents operation of relay 10 if the temperature of element 1 should get above the predetermined value when the supply is D.C.
