Patent GB-237326-A (GB)
Title: Improvements in or relating to pneumatic conveyors for cotton or the like
IPC: B01D45/08
Filed: 1924-04-11
Abstract: 237,326. Brooks & Doxey (1920), Ltd., and Newell, S. April 11, 1924. Feeding openers &c.-In a pneumatic conveyer for cotton &c., plates or grids are mounted in a dust box so that they are capable of oscillation by air passing through the conveyer. As shown, toothed racks 3, 4 within the dust-box are notched to support division plates 6, which are formed with arms resting in the notches. The passage of air and cotton through the dust-box causes the plates to swing gently so that the dust freed from the cotton passes through the plates without choking them. The floor is hinged and provided with a catch, for removal of dust. A handhole is provided on the cover.

Abstract: 996,796. Percussive tools. P. & V. (MINING & ENGINEERING) Ltd. June 9, 1964 [March 9, 1963], No. 9312/63. Heading B4C. A percussive tool, such as a rock drill, comprises a shank provided at one end with at least one hard metal insert formed from sintered material and shaped with a cutting edge or point, the shank also being formed from a sintered material having different characteristics from those of the insert. The shank may be preformed with a groove for the preformed insert the latter being brazed into the groove. Alternatively, the insert and shank may be formed as separate non-sintered pressings, the insert being located in the groove with clearance so as to allow metal powder or other bonding material to be located around the insert, and the whole unit then subjected to a sintering process. The shank may be formed with a tapered or threaded socket for a drill rod and may be provided with a hole for cooling liquid. The inserts may be located in a straight line or cruciform shape.

Title: Improvements in storage and reclaiming plant for gravel and like material
IPC: B65G53/30
Filed: 1942-07-06
Abstract: 559,241. Washing granular material. PHIPPS, J. D. B. July 6, 1942, No. 9356. [Class 82 (ii)] [Also in Groups XXVIII and XXX] In a storage and reclaiming plant in which gravel or like material is stored under liquid for removal by a pump, the storage basin 1 is circular and the pump 6 is mounted on a central turntable 5 with its suction 11 extending radially and with its delivery vertically upwards to a discharge pipe 7 having a swivelling joint 8 vertically above the centre of the turntable. The basin 1 may be concrete lined with a slope equal to the natural angle of repose of the gravel. A cylindrical pump chamber 2 of reinforced concrete with large entry ports 3 houses a mushroom-shaded platform 4 for the turntable 5 which has a lever and clamping means operable from a walkway 12. A staircase 14 and a covered portion 13, with parallel side walls 17, give access to the chamber 2 and its roof which carries a boiling box 9 and a vibrating screen 10. The walls 17, together with radial walls 15. subdivide the basin for different grades of material. The material is delivered by a conveyer 19 to a screen 20 which rejects the large material 21. The water and finer fraction pass through the screen 10 to a launder 25, whilst the coarser fraction either passes by a conveyer 22 to storage bins, or by a conveyer 23 to a crusher 24 and thence to the space between the walls 17. From the storage bins the material may be fed direct, or through a second crusher, to the main storage by a stocking conveyer 26 which delivers it to a pivoted radial conveyer 27 or to two fixed radial conveyers. The suction 11 may have a shield on its outer end. According to the Provisional Specification the suction may be carried by a radially extending arm.

Title: Process for the production of high-polymeric alkyl and aryl-siloxanes
IPC: C08K5/04
Filed: 1960-03-17
Abstract: High-polymeric siloxanes are obtained from lower polymeric siloxanes containing si-bonded OH groups by adding thereto a carboxylic acid halide in amount of from 0,1 to 1% (inclusive) by weight.  Halides specified are acetyl chloride, acetyl bromide, chloracetyl chloride, 2-chlorophenoxyacetyl chloride, propionyl chloride, 3-chloropropionyl chloride; isovaleric, stearic, oleic, oxalic and succinic acid chlorides.  Residual acid chloride and its reaction products, when all are volatile, can be removed from the polymer by blowing, if desired, under vacuum.  In a typical Example (1) an a -o -dihydroxydimethylpolysiloxane of 18,000 cs. at 20 DEG C. was mixed with acetyl chloride and kneaded for 5 hours at room temperature to yield a siloxane of 6,000,000 cs. viscosity at 20 DEG C.  This polymer was then mixed with silica, diphenylsilanediol and dicumyl peroxide and heat cured to an elastomer.

IPC: A23C19/09
Filed: 1962-03-13
Abstract: In texturizing cured Swiss, e.g. Emmenthaler cheese, the cheese, preferably rindless, is cut into slices, having hydrophilic surfaces and thicknesses less than 1/2 inch, e.g. 1/8 inch, and the slices are brought into contact with an aqueous solution of common salt, as by wrapping and sealing them with up to 6.4% of their weight of a 27% salt solution, e.g. in an atmosphere of nitrogen, in a wrapper, until the salt solution is substantially completely absorbed by, and evenly distributed throughout, the cheese, e.g. to increase its salt (Na Ce) content by a value not exceeding 2% by weight.  The wrapper may be a moisture-resistant, flexible sheet or film of regenerated cellulose, polyvinyl chloride, polyvinyl acetate, polyethylene or polyvinylidene chloride.  Specification 931,289 and U.S.A. Specification 2,494,636 are referred to.

Abstract: 1,150,087. Rotary positive-displacement I.C. engines. R.A. CREETH. July 5, 1966 [April 6, 1965], No.9623/65. Heading F1F. A rotary positive-displacement I. C. engine includes a housing 15, Fig. 2, containing a pair of rotors 10, 11, Fig.1, which have mutually perpendicular axes of rotation, assymetrically concaved edges, and peripheral recesses 24 on each of them, to permit projections 25 on the other rotor to pass therethrough, the rotors being synchronously coupled to each by gear-wheels 16 - - 20. An inlet port 30 for fuel-and-air mixture is located in the housing so that the recesses 24 in the rotor 10 are periodically and sequentially brought into register therewith, an exhaust port 31 for the spent products of combustion being located similarly relative to the recesses in the rotor 11. During operation of the engine, the mixture is displaced by the rotor 10 such that it is compressed between a leading face 28 of one of the projections 25 on said rotor, and a side of one of the projections on the other rotor farthest from the gear 20, the compressed mixture being ignited in a combustion chamber 35 within the housing by a spark-plug 36. The products of combustion are expanded in a chamber between the projection 25 on the rotor 10 adjacent the chamber 35 and the trailing face 29 of the uppermost projection on the rotor 11 so that useful torque is applied to a shaft 13 carrying the gear-wheel 20. Residual combustion-products in the recesses 24 within the rotor 11 are discharged through a port 32. Alternatively, the engine is adapted for compressionignition of the fuel.

Title: Apparatus for recording and reading data on optical way

IPC: G11B7/127
Filed: 1991-07-05
Abstract: The Liesst effect is understood as being the transition from the low-spin state to the high-spin state, associated with which in the case of many transition metal compounds is a characteristic colour change. By irradiating with light of suitable wavelength, the transition from one spin state into the other is brought about and reversed again. One of a plurality of light sources (L1, L2, L3) of different wavelength can be positioned according to choice in front of the entrance of an optical arrangement which focuses the light beam of this light source on a recording medium (AT). The recording medium (AT) reflects the light emitted by the light source onto a photodetector. The light sources (L1, L2, L3) may be located, for example, on a common support which is designed as a rail (S1), a rotatable disc or a drum. <IMAGE>

Abstract: Casting pattern is vented through metallic, ceramic or plastic based filter materials or their combination, with pores of 0.3-50 microns. Thee size of pores may be regulated in some cases. The plastic material used for the casting produces a wetting circumferential angle greater than 50 deg, depending on the conditions of processing. Thee wetting circumferential angle is produced by the filter material itself or by suitable treatment of it. - The casting pattern is formed so that: the filter material is located on its upper part, or on the planes of split, so that its ability to change position or shape is retained in some cases. Venting the pattern is demonstrated by the casting of insulation bodies contg highly tensioned, hollow, fibre reinforced cores.
