Title: Device for dispensing measured quantities of liquid for washing machines or like apparatus
IPC: G01F11/28
Filed: 1960-09-06
Abstract: 967,436. Delivering measured quantities of liquid. C. MOLLER. Sept. 6, 1960, No. 30656/60. Heading B8N. A dispenser for delivering measured quantities of liquid to a washing machine or the like comprises a measuring container 9, Fig. 1, connected by a pipe 4 to a reservoir 1 which is arranged with its bottom at a higher level than the top of the container, an outlet pipe 12 for discharging measured quantities of liquid from the container 9 and arranged so that it extends upwardly from substantially the bottom of the container to a level higher than the maximum liquid level attainable in the reservoir, and a valve-controlled pipe 16 connected to a compressed air supply 21 and associated with a port for exhausting air in the container to atmosphere. The funnel-shaped upper end 13 of the pipe 12 is housed in a spill box 14 having an outlet pipe 15 leading to the washing machine. A mercury manometer 19 is connected to the air supply pipe 16. In use, the valve 20 of the conduit 16 is set to allow air from the container 9 to pass to atmosphere so that the liquid in the system levels out in the pipes, the container 9 being completely filled. The valve is then changed over to pass air into the container 9 to empty it to an extent determined by the manometer 19 closing on electric circuit which, in turn, closes the valve 20; the manometer operates the valve at a pressure upon the height of the free column of liquid in the pipe 12 and this depends upon the volume of liquid dispensed. In a modification, the pipe 12, box 14 and pipe 18 are replaced by an inverted U-tube having a small straight open pipe section at its uppermost point to prevent siphoning of the liquid out of the container 9 when it is only partly discharged by compressed air; the open pipe section is unnecessary if the container 9 is to be emptied each time it dispenses. In the further modification of Fig. 3 the pipe 27 between the reservoir 1 and container 9 is fitted with a non-return valve 31 and the air supply pipe is in the form of a sinuous tube 36 ... 39 with an adjustable permanently-open air vent 35; the bends 36, 38, 39 are filled with oil or glycerine to prevent vapour from the liquid in the container 9 penetrating to the valve 20. The container 9 is transparent and has a photoelectric system 40, 41 disposed on its opposite sides for coaction with a float 42 in the container and shutting off the valve 20 when the desired quantity of liquid has been discharged.

Filed: 1965-07-20
Abstract: An insulating varnish is made from the reaction product of (a) of a polyester containing free carboxyl groups and derived from terephthalic acid, at least one polyhydric alcohol, and tris(2 - hydroxyethyl)isocyanurate and/or tris(2-carboxyethyl)isocyanurate with (b) a condensate containing free hydroxyl and amino groups of trimellitic acid tris (ethylene glycol) ester and an aromatic diamine.  The preferred polyol in (a) is ethylene glycol.  Suitable diamines in (b) are those of formula p,p1-H2N.C6H4.X.C6H4.NH2 wherein X is -(-CH2-)-n, -O-, -S-, or -SO2-, n being 1-4.  It is preferred that the molar ratio of terephthalate to isocyanurate residues be about 2:1 and that the weight ratio of (a) : (b) be about 1:1.  In examples polyesters are obtained by condensing, i.p.o. Li naphthenate, dimethyl terephthalate, ethylene glycol and tris(2-hydroxyethyl)iso-cyanurate or tris(2-carboxyethyl)isocyanurate and are then reacted with a product derived from trimellitic acid tris(ethylene glycol) ester and methylene dianiline.  The products are dissolved in a cresol/solvent naphtha mixture with a polybutyltitanate catalyst, and used to coat wires.  A comparative example uses a terephthalate/ethylene glycol/glycerol polyester reacted with a trimellitic anhydride/methylene dianiline condensate.ALSO:An insulating varnish for metal wires comprises the reaction product of (a) a free carboxyl-containing polyester from terephthalic acid, a polyhydric alcohol and tris (2-hydroxy-ethyl) isocyanurate or tris (2-carboxyethyl) isocyanurate and (b) a condensate of trimellitic acid tris (ethylene glycol) ester and an aromatic diamine, containing free hydroxyl and amino groups.

Abstract: 971, 520. Photographic copying cameras. LANSTON INDUSTRIES Inc. Aug. 13, 1962, No. 31033/62. Heading G2A. A photographic copying camera has an upright frame, with a horizontally extending copy holder and a horizontally extending film holder mounted on opposite sides of the frame, a lens carrier mounted on the frame and having parts extending over the holders, means for reflecting light from one holder to the other in a path comprising vertical and horizontal sections, and means for relative movement between the lens carrier and the holders. As shown, the camera is built on an upright supporting frame consisting of front and back plates (20) and a top plate 22, the frame resting on a base 17. A copy holder table 26 is mounted on one side of the frame, and a film holder table 27 on the other. The tables are removably mounted on carriages movable vertically on the frame by means of screw shafts 44, which are controlled by electric motors 48, 49. A lens and reflector carrier 28 is mounted on the frame above the tables, and can be moved up and down by further motor-controlled screw shafts 57. On the carrier is supported a central lens 64 having a horizontal optical axis, and further lenses 70, 71 having vertical optical axes, directed respectively towards the two holder tables 26, 27. Lenses 70, 71 are mounted on boards which can be moved laterally by rack and pinion means (Fig. 5, not shown), so that they can be adjusted over different parts of the holder tables. Carrier 28 also has two reflectors 80, 81, arranged at a 45 degrees inclination. In operation, a copy is placed on table 26, and illuminated from below. The image is directed upwardly to reflector 80, across to reflector 81, and then down on to a light-sensitive film on table 27. If lens 64 only is used, an approximately 1 : 1 magnification is obtained, which can be varied by vertical adjustment of the tables. If an enlargement is required, lens 70 only is used, and similarly lens 71 only is used when a greatly reduced image such as a microfilm is required. If the part of the carrier 28 containing reflector 81 and lens 71 is removed altogether, as in Fig. 13, the image can be thrown on to a vertical panel 112 provided with a screen or sensitised film sheet 111. The panel may be adjustable towards lens 64 to vary the magnification. The tables may be of the type shown in Fig. 9, having channels 89, 90 on the upper surface which can be evacuated so as to hold a copy down flat. A number of retractable pins 95 can also be provided, to locate a sheet in a particular position on the table.

Filed: 1938-10-27
Abstract: 511,336. Magnetic tests. UNGER, F., and HILPERT, R. S. Oct. 27, 1938, No. 31104. Convention date, Nov. 13, 1937. Drawings to to Specification. [Class 37] A ferro-magnetic suspension for use in a test vessel to render visible, and retain, magnetic field images, has the proportion of ferromagnetic addition relative to the bottom area of the test vessel such that, after the deposition of a bottom layer one particle thick, the deposition of further easily movable layers is avoided. The deposited layer preferably covers only about 20 per cent. of the bottom of the test vessel, which is preferably irregularly roughened, in a manner corresponding to the particle size, so that the suspension, once deposited cannot readily be moved by currents in the suspending medium thereby enhancing the retention of field images. Suspensions of iron oxides and sulphides and iron carbonyl in, e.g. water, are referred to. The particle size of the powder addition is less than 1/20th m.m. and the suspension in the test vessel may be under a super-atmospheric pressure.
Patent GB-485105-A (GB)
Title: Improvements relating to the manufacture of voltolized products from mineral oils
IPC: C10G71/02
Filed: 1936-11-13
Abstract: Condensation products are prepared from mineral oils containing paraffinic and non-paraffinic components, e.g. lubricating oils boiling above 400 DEG  F., by subjecting to the action of a silent electric discharge a non-paraffinic concentrate obtained by the extraction of the oil with a liquid consisting solely of a solvent having a preferential solvent action on the non-paraffinic components of the oil.  The products may be used as lubricating oils, or may be added to other oils to raise the viscosity thereof, to inhibit oxidation, or to depress the pour point.  The non-paraffinic concentrate may be mixed with other oils, e.g. mineral oils which are less paraffinic than the oil from which the concentrate is prepared, synthetic glycerides, or animal, vegetable and fish oils, of the nature of esters, prior to or during the voltolization.  The addition of sulphur or soluble sulphur containing compounds to the concentrate before voltolization increases the effectiveness of the product as an oxidation inhibitor.  In examples: (1) a lubricating oil obtained by the distillation of crude petroleum is extracted with phenol, the extract mixed with rapeseed oil and the blend voltolized; (2) an extract obtained as in example (1) is heated with flowers of sulphur before blending with the rapeseed oil; (5) a burning oil fraction is extracted with liquid sulphur dioxide, the extract is destructively hydrogenated and the product mixed with a refined lubricating oil distillate, the blend being then heated with flowers of sulphur and voltolized.  Specification 449,717 is referred to.

The beating-up wheel 10 of a circular loom has blades 11 of involute form, the generating circle of the involute being tangential to the mean plane 18, or, if the shed is vertical, to the corresponding mean cylindrical surface of the shed. The tip 16 of each blade is rounded and the edge that does not engage the weft may be cut away as at 15 at the tip. The blades are mounted obliquely with respect to the wheel and the tip of each blade is slightly twisted ; this ensures that the blades remain parallel (see Fig. 3) to the warps 12, 13. The rim of the wheel 10 does not touch the warps. If the axis of the wheel is inclined to the plane 18 of the shed, the operative margins 17 of the blades may lie in a conical surface coaxial with the wheel. The wheel may lie as shown in Fig. 5 or Fig. 7 in either a horizontal or vertical loom. Alternatively, the wheel may lie in a position which is a combination of those shown in Figs. 5 and 7.
Patent GB-1079405-A (GB)
Title: Glazed alumina substrates
IPC: C04B41/89
Filed: 1964-08-04
Abstract: A fired alumina ceramic film has on at least one surface a glaze coating which does not soften below 700 DEG  C.  The film is not more than 0.1 inch thick and has a camber less than 0.004 inch/inch in any direction in the plane of the film.  The coating is bubble free and penetrates the surface of the film and is firmly anchored thereto. The coating is uniform with a weight of 0.08-0.12 g./in.2, and is substantially free of the oxides of K and Na.  The surface of the coating is free of pits and cracks and so smooth as to give a reading of not more than 1.0 micro-inch (Centre Line Average) when measured with a "Tallysurf" tester.  The coefficient of thermal expansion of the coating is sufficiently analogous to that of the alumina film and the adherence is so firm, that after at least three boiling-water/icewater immersion cycles no cracking or spalling of the glaze occurs.  Tantalum may be sputtered on the glazed film for production of a component for an electric circuit.  The alumina film contains at least 90% alumina by weight, and may also contain, e.g., SiO2, manganese oxide and alkaline earth oxides. An example of the composition is in per cent by weight, Al2O3, 95.5; SiO2, 3.2; MgO, 1.1; CaO, 0.2.  Raw material is ball milled with an organic binder, and the slip is then de-aired and applied to a smooth carrier, e.g. "Cellophane" (Trade Mark) as a coating of uniform thickness and density.  It may then be stamped with score lines or holes for separation or perforation of the film after glazing.  It is then fired at a maximum temperature of 3050 DEG  F., and is thereafter cleaned.  The glaze frit may comprise, in per cent by weight: PbO, not more than 40; SiO2, 30-60; bivalent metal oxide, e.g. alkaline earth oxide, at least 5%; B2O3, at least 3%; oxides of Na and K, not more than 5% in total; a composition exemplified is: SiO2, 40.7; B2O3, 11.1; Al2O3, 3.5; PbO, 31.6; CaO, 9.8; Na2O, 1.9; K2O, 1.4.  To this frit may be added, e.g., 8% kaolin.  Based on the weight of inorganic solids, 55% water, 3% glycerine and 1.5% methyl cellulose are admixed, and the whole milled to form a slip, which may be applied, e.g. by spraying.  The article is then air-dried and fired in air at 1020 DEG  C.

Abstract: 634,209. Diffusers for grinding-machines. HUTCHINS, C. A., and HOVIS, Ltd. Oct. 17, 1945, No. 31395/47. Divided out of 634,147. [Class 58] [Also in Group II] A diffuser used in combination with an enclosed cereal-grinding machine (or other mill unit) comprises either a tapered conduit (open at its larger end to provide an air inlet or enhaust outlet and closed at the other) extending along the length of the mill unit and having a uniform slot along its length, or a uniform conduit (open at one end to provide an air inlet or exhaust outlet and closed at the other) extending along the length of the mill unit and having a longitudinal tapering slot (or alternative arrangement of graduated openings), or a combination of tapered conduit and tapered slot. As shown, an inlet-air diffuser 17 tapers internally from a maximum section at the inlet to a minimum at the other end which is closed at 171, the outlet for the air consisting of a longitudinal tapering slot 172 with its narrow end nearer the inlet 170. As an alternative, the slot may be of uniform width and in another alternative the conduit may be of uniform section with a longitudinal tapering slot having its narrow end nearer the air inlet. An exhaust diffuser 18 comprises two tapering and contiguous conduits 183, 184 with a longitudinal tapering slot 185 connecting them, the narrower end being nearer the inlet 182 and also another longitudinal tapering slot 186 for admission of exhaust air from the mill casing the narrow end being nearer the exhaust outlet 181. Alternatively the conduits 183,184 may be tapering and contiguous as shown but the slots 185, 186 may be of uniform width. In another alternative, the diffuser 18 may comprise two parallel and contiguous uniform sectioned conduits in which the slots are tapered so that the narrow end of the one between the conduits is nearer the inlet and of the other nearer the exhaust outlet. The longitudinal slots may have baffle plates on the outside to reduce the velocity of the air drawn towards the exhaust diffuser from inside the mill. The inlet air conduit of the inlet and exhaust diffusers may start from a common point in the air supply as shown and be provided with a valve 20 to control the inlet-air . stream. The exhaust-air diffuser may be employed in conjunction with a normal exhaust system on a grinding machine or other mill unit the inlet being open to atmosphere and fitted with a regulating valve (see Fig. 7 not shown). Specification 634,147 is referred to.

Title: A method and apparatus for the separation of solid constituents of a partly used photographic processing liquid
IPC: B01D29/00
Filed: 1959-09-15
Abstract: 916,611. Photographic processing apparatus. AGFA A.G. Sept. 15, 1959 [Sept. 22, 1958], No. 31489/59. Class 98 (2). [Also in Group I] A processing liquid such as photographic developer solution is subjected, while in circulation, to pressure-free filtration by passage in a substantially horizontal direction through a filter of mesh diameter 0.2-5 mm. In the developing tank of Fig. 1, liquid is continuously withdrawn from the tank 1 through an upper passage 4 and returned through a lower passage 5, a propeller 7 in the circulating channel 6 providing the driving force. In passage 4 is placed the filter shown in more detail by Fig. 2. The filter is contained in a removable container 18, and is preferably made of a mesh of synthetic resin fibres, joined by synthetic resin adhesive. It may have two different components, i.e. a wide mesh 17a and a smaller mesh 17b. As shown, the wide mesh increases in length in an upward direction, with a corresponding decrease in the length of the narrow mesh component. The narrow mesh will become clogged first, when the liquid can still pass through the wider mesh. Even when that too becomes clogged, the liquid can pass over the top of the filter. In the arrangement of Fig. 3, the filters are in the form of strips 25 extending in a radial direction from the wall of a cylindrical tank 21. Film strips 32 are stretched between supporting spokes 30, 31. A propeller 45 circulates the liquid in the tank by causing it to pass down a central tube 29 and outwards. Solid particles in the liquid tend to move towards the periphery of the tank, where the filters are located, due to centrifugal action. In a further embodiment (Fig. 5, not shown) the propeller is omitted, and the spokes 30, 31 caused to rotate on a central shaft, so that the moving film strips 32 themselves cause the liquid to circulate. At the same time this shaft can be given an axial pulsating or reciprocating motion, to detach solid particles which may be adhering to the film.
