Title: Burner assembly and method for controlling its operation to provide reduced emission of air pollutant
IPC: F23C99/00
Filed: 1974-05-12
Abstract: 1468364 Forced-draft burners TRW Inc 12 May 1974 [26 July 1973] 52350/73 Heading F4T A forced draft burner comprises means for supplying an oxidizer under pressure, an oxidizer supply tube 27 connected to said supply means and communicating with a combustion zone 16, e.g. defined by the wall 11 of a boiler, a fuel distribution tube 28 connected to means for supplying fuel under pressure and having an end part 30 projecting into the zone 16 and a plurality of radially oriented fuel outlet orifices 32 equispaced around the periphery of said part 30, and a deflector disc 31 projecting from said part 30 into the path of the oxidizer discharged from the annular passage 33 between tubes 27, 28, the total orifice area being determined in accordance with an equation as defined in claim 1. The Specification discloses relationships whereby, for a given heat output, the diameter of disc 31, the size and number of orifices 32, the fuel/oxidizer momentum ratio and the depth of penetration of the fuel jets from orifices 32 into the annular oxidizer stream may be selected to minimize the production of nitrogen oxides. With the selected parameters, a generally conical flame pattern 45, which is hollow and thin, results giving rise to heat transfer by convection and radiation to the walls 11 to control the temperature profile in order to minimize NO x  production by inducing rapid heat dissipation after combustion. NO x  production is also minimized by controlling the reactants' residence time in the combustion zone and by achieving good oxidizer/fuel mixing. The mixing is enhanced by oxidizing gas 42 deflected by disc 31. The temperature may also be controlled by the introduction of cooling gas to the interior of the flame 45 via tube 44 and deflector 46. The oxidizer may be air and the fuel may be gas, e.g. natural gas, or liquid fuel, e.g. oil. Liquid fuel is introduced tangentially into tube 28 at 36 and passes through a mixing element 38 having helical surfaces 39 wherein the fuel mixes with atomizing gas, e.g. air, steam, nitrogen or recirculated combustion products, introduced at 37, the atomizing gas subjecting the liquid to high shear forces at orifices 32. In a modification, the outlet end of tube 27 expands downstreamwards and the end part 30 of tube 28 also expands downstreamwards, the tube 28 and disc 31 being axially movable to adjust the cross-sectional of the annular oxidizer outlet, Fig. 13 (not shown).

Abstract: 1494488 Amusement and exercising apparatus F REBAJES 4 Dec 1974 [26 Dec 1973] 52547/74 Heading A6M [Also in Division B6] A shape-retaining flexible geometric structure for exercising and amusement purposes consists of a structural form 60 (Figs. 9 and 10) comprising a double-sided continuous curved strip having substantially; uniform resiliency, each side having four points of inflection 66 providing four surface portions having successive concave and convex contours 68 and 70, the shape being retained by the intrinsic balance of elastic stresses so that the strip is capable of retaining the shape of the form in an infinite number of positions of translation of any arbitrarily selected region of the strip along a path outlined by the shape of the form. "Uniform resiliently" means that the strip has substantially the same elastic properties throughout its length. The form may be constructed from two open ended annular strips 12 and 32 (Fig. 4) having upper surfaces 14 and 34, and lower surfaces 16 and 36, made of resilient flexible material (e.g. cardboard, sheet metal or elastomeric plastics sheet). The strips are concentrically disposed one on top of the other, and one end portion 20 of the strip 32 is connected to 'an end portion 42. of the other strip 12 (e.g. with adhesive or screws and wing nuts 52), to form a joint 50. The combined strip is then extended along its axis of symmetry to form a helix (Fig. 3). A free end portion 22 or 40 is bent in such a way that it is disposed adjacent to the other free end portion 40 or 22 with the original lower surfaces 16' and 36' (Fig. 5) facing each other. The end portions 40 and 22 are then bent inwardly and brought towards each other to align the lower surfaces 16' and 36' into a common plane, and the ends are then-joined together to give the required structural form. The form may be modified by forming slits or triangular projections along the inner or outer edges of the strip, or by providing projections or legs at points on the external edge so that the structure can stand on a flat surface. The internal opening of the form can be other than circular and may be asymmetrically disposed.

Abstract: 1404265 Viscometer RIZHSKY ORDENA TRUDOVOGO KRASNOGO ZNAMENI POLITEKHNICHESKY INSTITUT 20 Nov 1973 53888/73 Heading G1S A rotor 11 having a knurled surface is connected to one half shaft 7 of a differential gear 2-6 and is rotated in the medium being tested for viscosity by an electric motor 10 thro' gearing 9. The half shaft 8 has a threaded portion 16 on which a nut 15 runs and a centrifugal clutch 19 having weights 20 and guides 21 is secured to a thrust bearing 18. The half shaft 8 extends further to support a disc 23 mounting a flat Archimedean spiral scale (24), Fig.2 (not shown), and as the disc 23 rotates it winds a thread 26 with an indicator ball 29 on a post 25 and provides an indication on the scale. Springs 13 are connected at one end to the shaft 8 and at the other end to a cup 14 which slidably engages the nut 15, and stronger springs 17 are connected to the outer surface of the cup 14 and to the housing 1. In operation with the rotor 11 in air and the motor 10 rotating, the pinions 5 and 6 will run around the gear 4 which is held stationary with the shaft 8 by the springs. When the rotor 11 is immersed into the test medium the reaction torque on 11 will increase and overcome the reaction torque on shaft 8 so that 7 and 11 will slow down or stop whilst 8 will rotate. As a result the springs 13 will be wound up and the nut 15 displaced to engage the bearing 18 to rotate the cup 14 and twist the more powerful springs 17. The latter will be twisted until the reaction torque applied to the shaft 8 is counterbalanced by the torque on the shaft 7 so that the gear 4 will stop and gear 3 be rotated. At this instance readings are taken from the scale. At the instant of balance between the torques on 7 and 8 the weights 20 will move out and engage the housing walls 1 to damp the abrupt oscillations developed in 7 and 8.

Cashew nut kernels are peeled by forming them into a bed and subjecting the bed to a blast of air from at least one side. As shown, apparatus for this purpose comprises a pair of endless perforated bands 4, 5 having juxtaposed runs spaced sufficiently to accommodate the largest dimension of the kernels such that a bed consisting of juxtaposed kernels may be formed by feeding the kernels in a single layer from a hopper 14 by means of a vibratory feeder 15, the bed being confined laterally by spacers (12, Fig. 3, not shown) and being caused to travel between lower and upper manifolds 9, 10 by continuously driving the bands in synchronism. Nozzles (11, Figs. 2 and 3, not shown) are provided along the transversely extending portions of the manifolds to direct jets of air through the perforated bands into the bed of kernels, the nozzles being staggered so that the jets do not interfere with each other. Complete peeling of all the kernels is ensured by first drying the kernels to reduce their moisture content to 2¢-3 per cent, then passing the dried kernels through a series of machines as shown with intermediate sorting stages to remove from the peeled kernels any broken fragments, the air pressure used being increased in each succeeding machine from 3 Kg/cm<SP>2</SP> to 8 or 9 Kg/cm<SP>2</SP> in the final machine, whereby the number of broken kernels is said to be reduced to a minimum.

Title: Improvements in or relating to aluminum oxide gels
IPC: C01F7/428
Filed: 1966-12-12
Abstract: Spheroidal aluminium oxide gels are prepared by feeding drops of a coagulable aqueous slurry of hydrous alumina through a column of water-immiscible liquid coagulation medium, the hydrous alumina having an alumina monohydrate to amorphous hydrous alumina ratio of at least 0.5/1 and the monohydrate having a crystallite size of less than 65<\>rA. The aqueous slurry may be prepared by reacting finely divided aluminium of surface area of 7,5000 to 1,000,000 sq. mm./g. with water and a water soluble lower fatty acid (of 1 or 2 carbon atoms per molecules) such as formic acid in the ratio of 1 mole of acid/2-30 gram atoms of aluminium/at least 18 moles of water at 60-250 DEG  C. and at a pressure that will maintain the liquid phase, thus forming by acid hydrolysis the aqueous slurry of hydrous alumina.  The liquid coagulation medium may be a mineral oil of sufficient viscosity to produce spheroidal particles and as an aid to coagulation, ammonia is passed up the column containing this medium. From 1 to 65% based on the total solids in the slurry, of a solid filler e.g. alumina containing materials, silica containing materials and/or starch may be added to the slurry.  1 to 5% of carbon and/or 1 to 20% (as alumina based on the alumina in the slurry) of aluminium oxychloride may be added, and in the case of the latter addition, the pH of the slurry will bein the range 3.3-5.5.  The particles formed by the above process, are drained, dried and calcined to form porous adsorption catalytically-active aluminium oxide gel.  In Fig. 2 (not shown) the slurry is passed down a column 108 of mineral oil saturated with gaseous ammonia.  The gel so formed leaves the bottom of the column and is transported by a liquid flow through a serpentine arrangement of piping 107.  The transporting liquid, 6% aqueous ammonia, serves as an aging medium.  After aging, the spheres are drained, washed, dried and calcined.
