Title: Dispenser means for particulate and/or granular materials
Inventor: CAMERON DONALD
IPC: A01C7/12
Filed: 1967-01-27
Abstract: 1,203,271. Material dispenser. NATIONAL RESEARCH DEVELOPMENT CORP. 29 Jan., 1968 [27 Jan., 1967], No. 4238/67. Heading A1D. [Also in Division B8] A dispensing device for sowing seeds in an even manner consists of an upwardly tapering member 45 rotatable about its vertical axis of symmetry and having a top region 53 of minimum taper, a predetermined quantity of seeds being discharged on to this region 53 by valve means which may include a cam operated vertically movable sleeve 35. The seeds are retained at the base of member 45 by a close fitting wall 57 which is stationary relative to the axis of rotation of member 45. The bottom of member 45 is extended by a radially serrated flange 55 which slopes slightly downwards. Wall 57 is displaced outwardly at one point to permit a scraper blade 59 to remove seeds from the flange 55 of the slowly rotating member 45 and move them outwardly to fall down a shoot 61. Seed is stored in a compartment 21 in drum 25 which rotates in a casing 29. An aperture 31 in casing 29 allows seeds to fall through a funnel 33 into the sleeve 35. This sleeve is attached to a lever 37 which is actuated by rotation of a cam wheel 41 to lift sleeve 35 and allow discharge of seeds. Drum 25 rotates through 1/16 of a revolution for one rotation of the cam wheel so that only one portion of seed is discharged from the sleeve at any one time. The storage drum 25, the cam wheel 41 and member 45 are all driven by a common drive from a land wheel. A seed planter may consist of eight of these dispensers mounted together on a self propelled frame. Drum 25 may be replaced by the drum and hopper arrangement disclosed in Specification 1,203,272.

Abstract: 580,816. Fluid - actuated valves. BAXTER, B., and KANDARIAN, S. M. March 7, 1944, Nos. 4249 and 4250. Convention dates, Feb. 22, 1943, and Jan. 31, 1944. [Class 135] A valve suitable for insertion between a manual regulating valve on a gas storage vessel and the reducing valve in a gas welding system to prevent pressure surges reaching the reducing valve comprises a valve member 14 retained open by a spring 11 and having flutes on its external surface through which the gas passes to the outlet 13. The end of the valve is recessed at 18 and a-bleed passage 19 is controlled by a screw 22. When a sudden high inlet pressure exists, the valve 14 is closed and the gas leaks through the bleed passage 19 until the pressure in the outlet gradually increases and the valve again opens. In a modification shown in Fig. 4, the end of the valve 14a has a cavity 18a into which projects the end 25 of a fitting 24 on the inlet end of the housing ; this arrangement increases the effect of the sudden high pressure on the closing of the valve. The bleed passage is formed in this case around the thread of the screw 22 by making the bore 19a in the valve oversize before tapping ; a filter disc 27 is fitted adjacent the head of the screw 22.

Title: Brake proportioning valve
IPC: B60T8/26
Filed: 1966-02-02
Abstract: 1,137,522. Brake pressure proportioning valve; valves. HYDRASEARCH CO. Inc. 2 Feb., 1966 [9 Feb., 1965; 2 June, 1965], No. 4528/66. Headings F2F and F2V. An hydraulically operated brake pressure proportioning valve comprises a body 21 having a fluid inlet 22 and an outlet 23, a valve member 26 movable between first and second positions adjacent to the outlet and inlet respectively, connecting means comprising a passage 32 permitting hydraulic communication between outlet and inlet when the valve is in the first position, means 30a, 48 which seal the passage 32 when the valve is in its second position, a separate check valve 53 in the passage, the valve member 36 having a greater cross-sectional area exposed to the outlet pressure than that exposed to the inlet pressure, so that when the valve is in its second position the force exerted on the valve at the outlet is greater than that exerted thereon at the inlet until the hydraulic pressure at the inlet exceeds that at the outlet by a predetermined amount. The valve is positioned in the rear brake line of a vehicle brake system and supplies a lower hydraulic pressure at the rear brakes than that supplied to the front brakes after the master cylinder pressure exceeds a predetermined value, e.g. 450 p.s.i. The valve member 26 is normally biased by spring 39 into the first position. When the hydraulic pressure reaches the predetermined value the force on area A-1 is sufficiently in excess of that on area A-2 to move the valve to the second position where the valve face of member 48 abuts the seating 38 to seal off the inlet 22 from the outlet 23, the differential areas A-1, A-2 then providing the pressure ratio between inlet and outlet pressures. On brake release the inlet pressure falls and check valve 53 opens to allow fluid from the rear brake line to pass back to the inlet. The check valve 53 may be biased by a helical spring (Fig. 5, not shown) instead of the leaf spring shown in Fig. 2. The passage sealing valve 48 comprises a sleeve of resilient material such as nylon stiffened internally by a member 52 of hydraulically permeable material such as sintered porous bronze.

Filed: 1947-02-17
Abstract: 621,547. Axial-flow compressors. DAVIS, C. A., BILL, J. H., and MORLEY, F. W. W. Feb. 17, 1947, No. 4603. [Classes 110(i) and 110(iii)] A stator blade for an axial-flow compressor is formed at its root end with an axially and circumferentially extending platform, the latter being formed at its axially-spaced edges with a pair of surfaces facing towards and curved about the axis of the casing and intermediate said edges with an outwardly facing similarly curved surface the axial dimension of which is less than that of the platform; these surfaces form abutments for the retention of the blade in a circumferential groove in the casing. Each blade 12 comprises a platform 13 and a rib 23 which engage with flanges 17 and a web 16 formed on the inner wall of the casing. The engaging surfaces 18, 19 are curved about the casing axis. Each stage comprises an odd number of blades, which are assembled into the casing so that there is one more blade in the lower part 10 of the casing than in the upper part 11. The number of blades in each stage increases from stage to stage, so that the chord of the blade platforms decreases from stage to stage. The casing is split along a plane which is slightly inclined to a diamentral plane and is displaced therefrom by an amount which is substantially equal to the amount by which the blade platforms in the lower casing part 10 project beyond the diamentral plane. The blades are retained in each casing part 10, 11 by washers 25 which lie iri recesses 26 and engage recessed edges 30 of the platforms of the end blades. The clearance space between the blades and the casing wall may be used to effect tappings at appropriate stages, to avoid surging or for extracting cooling air. Each blade platform may have a pair of ribs 23 co-operating with a pair of webs 16. Specification 621,544 is referred to.

Title: Method of making artificial fibers or threads from viscose
IPC: D01F2/08
Filed: 1950-02-23
Abstract: Viscose having a sodium chloride salt point of from 3 to 12 is extruded into an aqueous non-regenerating coagulating bath containing 1 to 20 per cent by weight of acetic acid and from 5 to 30 per cent by weight of sodium sulphate, sodium acetate or a mixture of sodium sulphate and sodium acetate, the total concentration of salt and acetic acid being at least 15 per cent by weight and the so-formed continuous filaments being withdrawn from the bath and stretched. Preferably the filaments are subjected to the maximum stretch they will take without breaking, from 50 to 200 per cent.  The higher the salt point or the lower the cellulose/caustic soda ratio in the viscose the greater should be the concentration of acetic acid in the bath.  Thus it is preferred to use a bath containing 5 to 20 per cent acetic acid and 10 to 20 per cent sodium sulphate for a viscose of salt point 4 to 10, and a bath containing 5 to 15 per cent acetic acid and 5 to 20 per cent sodium sulphate for a viscose of salt point 4 to 6.9.  Viscoses of salt point 4 to 6 are preferred.  The concentration of acetic acid in the coagulating bath may be maintained by addition of fresh acid or of the calculated amount p of sulphuric acid to react with the sodium acetate formed.  The cellulose/caustic soda ratio may be 1 : 1, preferably 1.05 to 1, and should not exceed 2 : 1.  The cellulose xanthate filaments formed yield, after subsequent regeneration, yarn characterized by low extensibility, especially when wet, and good tenacity.  In an example a viscose of cellulose/caustic soda ratio 1.05 : 1 of normal viscosity and salt point of 4.4 is spun into an aqueous bath containing 10 per cent by weight of acetic acid and 10 per cent by weight of sodium sulphate at 50 DEG  C.  The cellulose xanthate filaments are given the maximum stretch short of rupture, and then regenerated in a bath at 40 DEG  C. containing 20 per cent by weight of sulphuric acid and 10 per cent by weight of sodium sulphate.  The yarn so obtained is twisted, washed, desulphurized and bleached in the usual manner.

Filed: 1941-04-08
Abstract: 549,206. Welding chain links. NORTH BRITISH ELECTRIC WELDING CO., Ltd., and GLOVER, T. S. April 8, 1941, No. 4693. [Class 83 (ii)] Studded chain links are made by welding together two complementary J-shaped segments, the longer limb of one of the segments having a transverse stud engaging the longer limb of the other segment. The segments 1, 2 which are provided with flashing allowances 5 are welded together at their ends. The ends in the vicinity of the free end of the stud 3 are previously deformed to a slight extent beyond the normal so that they are clear of the free end of the stud during welding. After welding the deformed side of the link is squeezed inwardly until the longer limb of the unstudded segment engages the free end of the stud. The free end of the stud which may be convexly curved in the plane of the link is concavely curved at 4 so as to engage saddle-fashion the longer limb of the segment 1 to prevent deformation out of the plane of the link. In a modification the planes of the welds are oblique to the length of the link instead of at right angles thereto.
