Title: Improvements in or relating to apparatus and method for measuring colour values
IPC: G01J3/46
Filed: 1949-04-21
Abstract: 677,129. Determining colour values. HALL, J. M. April 21, 1949 [April 24, 1948; April 8, 1949], Nos. 10596/49 and 10597/49. Classes 97 (i), 98 (i) and 98 (ii). Apparatus for determining the densities of three primary colours in a surface or transparency comprises a photometer having a mirror surface with a central aperture illuminated by a source and adapted to be located relative to the surface to be tested or a projected image of the transparency so that the latter can be seen by reflection in the mirror, means for interposing in each of the beams colour filters absorbing one primary colour but passing the others, and means for varying the light from at least one of the sources to effect a photometric balance without the colour filter, and further means to effect such a balance with the filters in position, the latter means indicating the amount of illumination change. As shown in Fig. 1, the mirror 12 is supported in a casing 11 and has a central aperture 13 illuminated by a lamp 15 through a sliding filter holder 16 and an adjustable diaphragm 9 comprising plates 37, 38, Fig. 3, slidable in opposite directions by rotation of a pinion 43 and having logarithmically curved edges 41, 42. A filter 23 correcting the colour temperature of the lamp 15, and a diffusing screen 24 are provided. The object to be tested is located beneath an aperture 28 in the base-plate 45 of the apparatus and is illuminated by a lamp 20 through a rotatable colour filter 21 and a colour temperature filter 56, the aperture 28 being viewed in an eyepiece 22 by reflection in the mirror 12. In operation, the apparatus is placed on white paper, the colour filters are removed, the diaphragm 9 opened and the lamp-house 19 vertically adjusted on the column 26 to give a photometric balance. The coloured object to be examined is then placed beneath the aperture 28 and identical colour filters absorbing one colour, e.g. blue, are placed before each lamp and the diaphragm 9 adjusted to give a balance. The movement of the diaphragm, indicated on a dial, gives a measure of the density of blue in the object. Further measurements give the red and yellow densities. For transparencies the lamp-house 19 is replaced by a photographic enlarger which projects an image of the transparency on to paper beneath the aperture 28 and which carries a sliding holder for the colour filters and has a diaphragm on the projection lens. The densities thus obtained assist in the estimation of correcting filters in copying the transparencies by colour photography. In a modification the colour filters may be located between the aperture 28 and the mirror 12 instead of at the enlarger. For photography, having determined the suitable colour correcting filters, the photometer may be used to determine the difference of density between the high-lights and shadows on the transparency, these values being used to calculate a suitable exposure for copying the transparency on to colour material.

Title: Improved method of separating by distillation the components of aqueous mixtures containing methanol and ethanol
IPC: B01D3/14
Filed: 1950-05-01
Abstract: <PICT:0698617/III/1> Aqueous ethanol which contains methanol, e.g. a sulphite or sulphate lye, is freed from methanol by a two-stage rectification process; a mixture comprising methanol, water and between 20 to 60 per cent by weight of ethanol is withdrawn as distillate from the first rectification column, and this distillate is then rectified in a second column to strip out the methanol and give aqueous ethanol, free from methanol, as bottoms.  An acidic mixture of methanol, water and about 12 per cent ethanol, supplied through pipe 1, is preheated in condenser 6 and then introduced through pipe 2 on to the top plate of column 3 which contains sixteen plates.  Column 3 is surmounted by column-section 4 which contains five to seven plates; and neutralizing lye is introduced through pipe 16.  Alcohol-free wash is discharged from the sump of column 3 through pipe 5.  All the condensate from condensers 6 and 7 is refluxed to section 4, from which a neutral solution containing methanol, water and 25 to 50 per cent of ethanol is withdrawn through pipe 9 and introduced into the side of fractionating-column 10, 11. This column has about 40 plates below the feed-inlet.  The condensed distillate from the head of the column, which contains methanol, ethanol and water, is partly returned to the head of the column, and partly withdrawn through line 14.  Aqueous ethanol free from methanol, is obtained from the sump of column 10 through pipe 15. The ternary mixture withdrawn from the head of column 11 may be fractionated to give methanol as "heads" and aqueous ethanol as "bottoms"; and the latter may be refluxed to column 10, 11, after adjustment of its composition to ensure that the relative concentration of the ethonal in the total feed to the column, conforms with the invention.  Fusel oil and/or other impurities may be withdrawn as a side-stream from column 10, 11.

Abstract: 914,571. Garment waistbands. AUTOMATIC BRAIDING CO. (NOTTINGHAM) Ltd. April 2, 1959 [April 3, 1958], No. 10746/58. Class 141. [Also in Group VIII] A garment waistband &c. comprises an elastic strip 1 of rubber &c. adhesively secured to a textile sheath 2 in which it is wholly or partly enclosed, and at least one stretchlimiting thread, cord, tape, &c. 3 attached at spaced locations to the strip 1 and/or sheath 2 so that the thread &c. is puckered or crimped when the band is relaxed. The thread 3 may be of crimped nylon or of inextensible material. Preferably the sheath is of knitted fabric, either on interlock or IXI weft-knitted fabric or a warp-knitted tricot fabric with the wales extending widthwise of the band. Alternatively, the sheath may be inextensible. In Fig. 4, the threads 3 are attached by adhesive stripes S which serve also for attachment of the sheath margins 2a, 2b to the strip 1. In a modification, Fig. 6 (not shown), the threads are attached to the opposite face FF of the strip. The edges 2c, 2d of the sheath may overlap, Fig. 4, or merely abut, or be spaced apart, Fig. 15, and may be symmetrically or asymmetrically located on the face of the strip. The rubber strip 1 may be the same width as the finished band, or narrower as in Fig. 4, or wider as in Fig. 11. The band is stitched in stretched condition to the inside or outside of the garment. In Figs. 7, 8 (not shown), the band conceals the raw edge of the garment fabric, the top of the band being above or flush with the folded edge of the garment. In Figs. 9, 10 (not shown), the band is folded to provide two limbs of equal or unequal length disposed on opposite sides of the garment fabric. If the rubber strip is narrower than the band, one of the two limbs may consist solely of the double thickness of sheath. If the rubber strip is wider than the band, Fig. 11, the band is attached so as to provide a beaded effect. In a modification. Fig. 15, a facing strip 5 covers the raw garment edge and open side of the sheath. In a further modification, Fig. 14 (not shown), the garment fabric itself is folded to form the sheath.

Title: Improvements in or relating to means for effecting the evaporation of water and the like
IPC: B01D1/00
Filed: 1941-09-23
Abstract: 553,019. Evaporation by infra-red radiation. REAVELL, J. A. Sept. 23, 1941, No. 10757/42. Divided out of 553,200, [Group XI]. [Class 32] [Also in Group XI] Evaporating and like operations are effected by means of infra-red radiation of wave lengths between 10,000 and 50,000 Angstrom units, the radiation being directed by elliptical or parabolic reflectors. Liquid is contained in a vessel a connected to a translucent vertical circulating tube c of fused silica or glass such as described in Specification 496,508, [Group XXIII], which is subject to radiation from two sources d, e associated with mirrors f, g which direct the radiation on the tube. The tube h is connected to a source of vacuum so that a "climbing film" effect is obtained in the tube c. A modification is described in which the tube c is replaced by a sinuous tube with horizontal portions which are heated by the radiation. Absorption of heat by the tube c may be minimized by directing a cooling current of air against it. The infra-red radiation may be derived from tungsten or carbon filament lamps operating at 1500 C. or from a rod or tube of ceramic material having a heated resistance wire wound thereon. Heat sensitive liquids such as blood, or solutions of vitamins or enzymes may be treated.

Title: Improvements in or relating to machine for molding plastic articles
Inventor: ZEUN LOUIS HERMAN
IPC: A23G3/02
Filed: 1954-04-13
Abstract: 751,530. Feeding candy &c. to moulding machines. PAUL, Inc., P. April 13, 1954, 10864/54. Class 87(2) In a machine for feeding plastic material, e.g. candy, from a hopper 31 into mould cavities 30 on the periphery of a drum 20, by the reciprocations of a ram 55 in the hopper, uniform pressure is exerted on the ram by the interposition of pressure control coupling means between the ram and the reciprocating mechanism. The ram is actuated by a bar 58 with both ends extending through the sides of the hopper and connected 'to levers 63, 64 mounted on fixed pivots 65. Each lever passes through a slot in a piston 67 and is pivoted to it at 66, the piston being slidable in a cylinder 68 or 69. Air pressure is maintained above the piston in the cylinder, regulated by valves 76, 77. A plug 80, secured to each cylinder 68, 69, closes its bottom and is pivoted to . the upper end of a link 86, the lower end of which is pivoted to a crank disc 89 which is driven by a chain and sprocket drive from the main drive shaft 29. The links 86 are thus actuated to raise and lower the cylinders 68, 69. The pistons 67, levers 63, 64, bar 58 and ram 55 are thus actuated through the controllable air pressure in the cylinders. The shaft 21 on which the drum 20 is mounted is driven by a worm 25, driven through bevel gearing from the shaft 29, which engages a series of rollers 23 on a disc 22 mounted on the shaft 21. Plungers 33, urged radially inwards with respect to the drum 20 by springs 38, close the mould cavities 30. Rollers 37 on the ends of the plunger stems engage adjustable cams 40, 41 at the mould filling and emptying positions respectively, the plungers moving outwards in the latter position to eject the moulded articles on to a belt 42. The empty moulds and the drum periphery are cleaned by liquid sprayed from a pipe 43, below which is a wiper blade 47. Air, which may be heated, is blown into the cavities from a pipe 45. and a blade 47a scrapes any residue of material from the drum. Scrap material drops into a perforated tray 48, surplus liquid-draining into a pan 50.

Title: Improvements in or relating to fluid pressurizing apparatus
IPC: F02C7/22
Filed: 1952-04-30
Abstract: 733,356. Centrifugal pumps; gas turbine plant. BENDIX AVIATION CORPORATION. April 30, 1952 [May 9, 1951], No. 10927/52. Addition to 708,732. Classes 110 (1) and 110 (3). [Also in Group XXIX] In a pressurizing apparatus comprising a pump and a fluid-actuated device for driving the pump, as described in the parent Specification, the valve mechanism which regulates admission of fluid under pressure to the pump driving device is associated with a control mechanism responsive to the fluid pressure at the fluid supply source and to the inlet pressure of the pump driving device. In a fuel pump for a jet-propulsion engine, the means described in the parent Specification for reducing the opening of the air inlet valve 66 of the driving turbine 34 if the pump discharge pressure becomes excessive is replaced by a means in which the enlarged head 108 of a valve 92 is subjected, by way of a passage 120 and the interior of a bellows 112, to the pressure within the admission chamber 60 of the turbine. The other end of the valve 92 is subjected, by way of a duct 102 and a chamber 100, to the pressure within the air inlet chamber 62. The areas of the opposite ends of the valve 92 are so related that when the pressure within chamber 60 exceeds a value which depends upon the value of the pressure within chamber 62, the valve 92 is moved to the left against the action of a spring 106, so that a reduced portion 104 of the valve provides communication between chamber 100 and a chamber 96 which in turn communicates by way of a duct 98 with the interior of a bellows 76 at the underside of valve 66. The valve 66 is thus subjected at its underside to the pressure within chamber 62, and is moved towards its seat 68 to reduce the pressure in chamber 60.
