Title: Improved apparatus for separating gaseous mixtures
IPC: B01D53/04
Filed: 1965-11-30
Abstract: A twin-bed gas separation apparatus of particular application in drying air is regenerated by a countercurrent stream bled from the purified effluent leaving the apparatus by control valves at the regenerating gas output end of each of the beds, flow of the input stream being directed to one or the other of the beds by means of two three-way flow-directing valves which are switched from one position to the other in response to the change in the system pressures when one control valve is opened and the other closed.  As shown diagrammatically in Fig. 2, compressed air to be dried enters valve 50 from duct 46, and is diverted along duct 20\sv to silica gel absorber 12 since duct 20 is closed by neoprene ball 70.  Similarly, passage 26 leading from absorber 10 is closed by a second neoprene ball 70, so that the bulk of the purified effluent from duct 26\sv leaves the apparatus by valve 84.  During this phase, control valve 34 is open while 34\sv is closed, so that a stream of dried effluent is bled off at valve 52 through orifice 72 in duct 26 to regenerate the loaded silica gel in absorber 10.  When regeneration has been completed, valve 34 is closed to allow repressurization (which may be assisted by passage of a stream from duct 26\sv through by-pass valve 90), whereupon valve 34\sv is opened, causing the ball valves 50 and 52\sv to switch the functions of absorbers 10 and 12.  In the specific construction illustrated in Fig. 1 (not shown), the two floating ball valves form part of a single structure, ducts 26 and 26\sv are disposed within the beds 10 and 12, and the control valves 34 are solenoid controlled and each have an orifice shut by contact with a flat resilient member.  In a variation (Fig. 7, not shown), instead of orifices 72 by-passes are provided having valves 140, 142 which may be adjusted so as to vary the rate of flow of the regenerating stream.  In a further modification (Fig. 5, not shown), the regenerating stream is bled from the effluent stream before it reaches the second flow-directing valve by means of devices 100, 102 whose construction is shown in Fig. 6 (not shown).  The effluent stream enters by passage 104 and leaves by passage 106, while the regenerating stream leaves by passage 108. Control member 124 supported by springs 116 and 118 which have linear characteristics has a conical projection 126 which co-operates with passage end 130 to give an annular orifice whose area varies in direct proportion with the rate of flow in line 104.

Title: Improvements in producing a visible and tactile grained pattern upon a surface of wood
IPC: B44F9/02
Filed: 1965-12-01
Abstract: 1,105,365. Wood graining L. G. BUCKLEY. 1 Dec., 1965, No. 50962/65. Heading B6G. A visible and tactile grained pattern is produced upon a surface of wood e.g. plywood of a variety having no distinct graining by embossing the surface to produce a tactile pattern of pronounced ridges and valleys, the valleys having varying widths and extending to various depths and the valleys and ridges being distinct to the touch but indistinct to the eye, applying a pigmenting material over the embossed surface, wiping off the pigmenting material thus removing substantial portions of the material from the ridges and valleys of only slight depth, and lesser portions of the material from the valleys of greater depth to produce concentrations of pigmenting material graduated according to the varying depths of the valleys. In the embodiment of the invention a lauan panel is treated. Other suitable woods are mentioned. The graining may simulate the Braining of walnut, or other wood. The surface of the panels may be embossed or otherwise indented with grooves to simulate planking, and the embossed graining in the different planks may be similarly or contrastingly pigmented. Prior to the application of the pigmenting material, the wood surface is coated with a sealant. The pigmenting material may be in liquid form, and may be of a chemical nature which affects the wood to discolour it where it is left in greatest concentration, i.e. to lighten or darken it, or may be a stain or paint. A finish coat may be applied over the grained surface.

Abstract: 1,176,190. Agglomerating ores for roasting. BOLIDEN AB. 16 Nov., 1967 [17 Nov., 1966], No. 52226/67. Heading C1A. A finely-divided sulphide-containing flotation concentrate, dried to a moisture content of 0-30% by volume is compressed by passing through a pair of rolls at a roll pressure above 0À5 tons/cm. roll length before passing to a fluidized-bed furnace, the resulting agglomeration being sufficient to prevent entrainment of material before completion of roasting. The rolls are preferably smooth and their speed of rotation may be varied. The agglomerated material may be stored prior to feeding to the furnace. Roll pressure may be 0À5-5 tons/cm. roll length. After rolling, oversized agglomerates may be broken up by a spiked roll. Sulphur may be incorporated as a binding agent by adding up to 5% by weight of finely ground sulphur which is heated to melting point during rolling, e.g. by injecting superheated steam or by electrothermal or induction heating, and then cooled in air. Alternatively, sulphates may be added in amount up to 10% by weight of concentrate by mixing with slightly moistened material; the salts dissolve during rolling and then crystallize. Preferably iron, zinc and lead oxides from the furnace are mixed with sulphuric acid (which may be obtained from roaster gases) and the reaction between them is completed as the material undergoes compression. A preferred binding agent for pyrites concentrate is magnetic pyrites, Fe9S10, of particle size less than 50 Ám, added in amount up to 10% by weight before rolling. Other binding agents specified are sulphite lye, sodium sulphate, bentonite. Specifications 917,480 and 1,165,519 are referred to.

Abstract: 1284433 Arithmetic circuitry; code converters TEKTRONIX Inc 27 Oct 1969 [28 Oct 1968] 52464/69 Headings G4A and G4H [Also in Division HI] A transistor matrix comprises a plurality of transistors having emitters interconnected in first groups corresponding respectively to first input values, and bases interconnected in second groups corresponding respectively to second input values, one of the transistors having common collector output means. In Fig. 1, one of switches A 0  to A 3  and one of switches B 0  to B 3  are closed to represent respective input numbers producing an output at one of points C 0  to C 6  representing the sum of the two inputs. Fig. 7 (not shown) shows two orders of a decimal adder, using a matrix as above (but with tenway inputs) in each decimal order, diodes (or diode-connected transistors) and connections being used to convert the 1-out-of-19 output of the lowest order into a 1-out-of-10 output and a carry, the carry, if equal to one, shifting one of the inputs to the next order to the next higher valued lead using 10 pairs of transistors. The matrix can be used for adding exponents in multiplication. A code converter could be produced using different interconnections in the matrix. Monolithic integrated construction of matrix.- An epitaxial N-type collector layer is grown on a P-type substrate and divided into rectangles, one per row of the matrix of Fig. 1, by diffusing in a P-type isolating grid. Base regions are diffused into the collector rectangles and emitter regions into the base regions, the whole being covered with an insulating layer etched to permit the base-base, emitter-emitter and external connections shown. Since each base region protrudes on both sides of the associated emitter region, the base-base connections do not need to cross over the emitter-emitter connections. The common collector outputs are simply respective connections to the collector rectangles and so also do not involve cross-overs. Strips of N-type material, of lower resistivity than the N-type collector layer, are provided beneath the latter in the substrate, one strip along the centre of the longer dimension of each collector rectangle (horizontally in Fig. 1).
