Patent GB-879368-A (GB)
Title: Improvements in pneumatic tyres
Inventor: SMITH REGINALD SARGENT JAMES
IPC: B29D30/26
Filed: 1957-03-06
Abstract: 879,368. Building pneumatic tyres. DUNLOP RUBBER CO. Ltd. Feb. 19, 1958 [March 6, 1957], No. 7371/57. Classes 144 (1) and 144 (2). In the " turn-over " method of building pneumatic tyres wherein a parallel cord ply 5 of cord fabric is transferred from an auxiliary drum 2, having an inflatable annular bag 3 coaxially supported thereon, to a building drum 1 by first inflating the bag 3 to force the outer surface of the ply 5 against a cylindrical cage 4 coaxially surrounding the auxiliary drum 2 and then effecting relative axial movement of the drum 1 and the cage 4 to transfer the ply 5 to the drum 1, the ply 5 is held firmly to the surface of the drum 1 as it is transferred thereto, and the drum 1 and cage 4 are relatively rotated during transfer so that the transferred ply has a cord angle which varies as desired across its axial width. As shown, a ply 5 with a cord angle of 70 degrees, Fig. 10, is laid on the auxiliary drum 2 with an end 5a turned down over the drum shoulder to be clamped thereagainst by the building drum 1, Fig. 4. On transfer of the ply, Fig. 5, the ply 5 is adhered to the building drum surface either by means of a layer of uncured rubber pre-laid on the drum surface, or by a suction effect, the drum in this case having a perforated surface communicating with an interior suction chamber. During the axial transfer movement of the cage 4, the drum 1 is braked against rotation, and the cage 4 is caused to rotate, for certain portions of its axial travel, in one or other direction by a cam mechanism (not shown) to produce the desired path of the cords across the ply such as shown in Fig. 11. In Figs. 10 and 11, a ply having an original uniform cord angle of 70 degrees is transferred to the drum 1 with cord angles of 90 degrees at the sidewall regions 7a, 7b and 60 degrees in the tread region. Where successive plies are cross laid, the rotations of the cage are effected in opposite directions respectively. Plies of any initial cord angle may be used to achieve any desired resultant cord path, and the apparatus may be used to make tyres of the form described in Specification 879,367. Specification 854,214 also is referred to.

Title: Improvements in or relating to the separation of particles of different densities by means of liquids
IPC: B03B5/44
Filed: 1929-03-08
Abstract: 331,841. Holmes, C. W. H., and Birtley Iron Co., Ltd. March 8, 1929. Wet-separating.-In gravity separation by immersion in liquid of density intermediate between the density of the coal or other material to be concentrated and that of the associated refuse, the crude coal, ore &c. is pretreated by spraying with oil or other substance, e.g. crude varnish, which will minimize the wetting of the mineral by the separating liquid. Coal may be sprayed with paraffin oil while passing over a bar screen prior to immersion for separation in a tank containing calcium chloride solution, or the oil may be floated on the calcium chloride solution so that the coal passes through the oil before it reaches the calcium chloride. The solution may be of specific gravity approximately 1.4, the heavier fraction separated in this tank being further treated in a solution of specific gravity 1.7, with or without a further treatment with oil. Zinc chloride may be used as the separating liquid and the process is particularly advantageous with large particles of coal and shale.

Abstract: 1,218,208. Vehicle suspensions. MONROE BELGIUM N.V. 19 Feb., 1968 [22 March, 1967], No. 8027/68. Heading B7D. [Also in Division F2] The suspension elements 12, 14, 16, 18 of a vehicle suspension system, Fig. 1, each consist of an hydraulic piston-cylinder shock absorber 20, Fig. 2, or 20<SP>1</SP>, Fig. 5, whose cylinder has one vehicle-connection member such as an eye 36 (36<SP>1</SP>) and whose piston-rod is directly (Fig. 2) or indirectly (Fig. 5) connected to a second vehicleconnection member 81, Fig. 2, or 190, Fig. 5. The shock absorber cylinder is surmounted by a variable-volume liquid chamber 68 (68<SP>1</SP>) which is equipped with a levelling valve 76 (76<SP>1</SP>) and is also connected to a hydropneumatic accumulator. The accumulator may either be a separate element 124, 126, 128 or 130, Fig. 1, connected to an inlet 154, Fig. 2, or it may be an element 132<SP>1</SP> combined in a single unit with the shock absorber and variable-volume chamber as in Fig. 5. The levelling valve 76 (76<SP>1</SP>) consists of a movable valve element 106 (106<SP>1</SP>) which is loaded by a spring 84 (84<SP>1</SP>) and which normally closes both an inlet and an outlet passage 98 (98<SP>1</SP>) and 100 (100<SP>1</SP>). Excessive displacement of the piston-rod 30 (30<SP>1</SP>) opens one of these channels and thereby connects the variable-volume chamber 68 (68<SP>1</SP>) either to a pump 226, Fig. 1, or to a reservoir 224, the excessive displacement thus being corrected. The four suspension elements of Fig. 1 are so interconnected that fluid is made to flow to the rear suspension elements 16, 18 whenever fluid is expelled from the front suspension elements 12, 14 and vice versa. Thus if e.g. the front wheels rise on a bump in the road, the rear wheels are hydraulically raised to prevent pitch. The means 252 and 254, Fig. 1, by which this anti-pitch interconnection is made are elements of the form shown in Fig. 4.
