Abstract: 417,942. Distributers for seeds. LEAKE, H. M., 10, Queen Edith's Way, Cambridge. April 12, 1933, 10966. [Class 6 (i).] A seed drill for sowing measured quantities of seed at spaced intervals comprises a distribution box having a seed discharge aperture in its peripheral wall, a seed distributer rotatable in the box and having a sloping or curved surface spaced from the inner surface of the box to provide an annular seed-receiving space, and also having a flange or rim with one or more pockets in its periphery adapted to register at intervals with the discharge aperture, a baffle in the box to ensure that only the seed in a pocket registering with the discharge aperture is discharged, and means for vibrating the distributer along the axis about which it rotates. The distribution boxes 5 are mounted near the ground on pivoted coulter levers 8 partially supported by springs 31 and connected by rods 12 and springs 13 to arms on a shaft adapted to be rocked by a lever 11 for raising the levers 8. The boxes 5 are fed from seed containers 4 and are cylindrical internally. The hollow distributers 15 are of cone or bell shape and are fixed on vertical co-axial shafts 16 driven through bevel gearing and telescopic shafts 20 from a cross shaft 22 driven from one of the travelling wheels 2 by chain gearing and a clutch operated by means of a lever 25. The distributers 15 are vibrated axially by the engagement of toothed wheels on the shafts 16 with adjustably mounted stationary toothed members. The rims 32 of the distributers 15 may be interchangeable according to the seeds to be discharged. They are provided with spaced pockets 33 open upwardly and outwardly. The baffles 34 consist of movable hollow cylinders fitting within the boxes 5 and each having a gap 35 at the lower part. The thickened lower edge 38 of each baffle fits closely against the distributer 15 and covers the pockets 33 beneath it. In it is a recess 37 registering with the discharge aperture 6. The baffle removes surplus seeds from the pockets and closes the upper ends of the pockets so as to prevent the discharge of any seeds other than those in the pocket registering with the aperture 6. The spacing of the seeds in the ground may be varied by changing the rims 32 or the driving gearing. Specifications 333,645, [Class 6 (i)], and 388,447 are referred to. The Provisional Specification describes a series of distributer boxes as being attached to one seed box, each distributer box having two outlets.

Title: Improved construction of hydraulic lifting or operating jack and like appliance
Inventor: LESLIE ALFRED COLLIS
IPC: B62B3/065
Filed: 1920-04-26
Abstract: 166,726. Collis, L. A. April 26, 1920. Jacks. - In hvdraulic jacks, the passage connecting the ends of the cylinder contains a pair of valves and a piston, and the pump is connected to the passage between the two valves, the arrangement being such that, by moving the valves, the opening to the non-working end of the cylinder is reduced and the ram descends slowly. The invention is described as applied to a jack for raising the platform of a hand truck. The cylinder 3, which is of greater length than the stroke of the ram, is secured to a casting ing 2 fixed to the frame 1 of the truck, and the ram 5 is attached to the lifting platform 7. The ends of the cylinder are connected by a passage 8, 9 controlled by valves 10, 11 and a piston 20. The passage 14 connects the pump cylinder 13 to the passage 8, 9. The ball valve 10 has its seating in a plug 16 screwed into a hole in the casting 2 and is either spring-controlled or limited in its movement by a bar 15. A plug 18 is screwed into an enlargement of the hole in the casting and has a central hole of two diameters in the larger part of which is the piston 20 having grooved sides 28. The piston 20 is of two diameters and during raising of the platform has it smaller part opposite the holes 25 in the plug. The piston 20 is attached to a rod 21 having a head 24 which bears against a cam 42. The disc valve 11 is carried by a stem 26 slidably mounted in the piston. When the cam 42 is turned by depressing a pedal, the piston 20 is pressed in until the grooves 28 form the only means of communication between the passages 8, 9, and the valve 11 is opened. Towards the end of the movement of the piston 20, the stem 26 comes against the valve 10, and, forcing it off its seating, releases the fluid from the working end of the cylinder. The piston 20 is connected to a bell-crank lever mounted on the cylinder or casting 2 in the path of the platform at such a position that, when the ram reaches the end of its stroke, the lever will be rocked, and the piston 20 pressed in to release the fluid. As soon as the ram has descended a distance sufficient to release the lever, the piston 20 will be forced out by the spring 23, and the movement of the ram will stop. The plunger 12 of the pump 13 is provided with teeth 31 which mesh with a toothed sector 32 mounted on a casing 33. A toothed rod 34 passing through a gland 35 in the top of the casing 33 meshes with the sector 32 and is connected by a collar 36 to the operating- handle 37. The bent end 38 of the handle 37 is connected by a link 39 to a lug 40 on a ring 41 surrounding the gland 35.

Title: Improvements in and relating to the propulsion and steering of watercraft
Inventor: DAVIES VICTOR NORMAN
IPC: B63H20/12
Filed: 1956-04-16
Abstract: 824,664. Regulating. SOUTHEND ENGINEERING CO. Ltd. April 16, 1957 [April 16, 1956], No. 11539/56. Class 7(6) [Also in Group XXXIII] A motor unit for a boat comprises a power unit, a propeller unit, and means for transmitting power from the power to the propeller unit, the boat being steered by a tiller mounted on the motor unit and itself adjustable relatively to that unit to actuate one or more of the control elements of the unit. The invention is described as applied to the outboard motor unit of Specification 710,083. The tiller bar 79 passes removably through the rigid engine casing 7 and by a longitudinal groove 80 engages a pin 81 in a surrounding control sleeve 52. This sleeve carries three cams 54, 55, 39 controlling respectively the throttle and ignition advance jointly, the magneto cut-out and the clutch. Assuming the engine to be at rest with the cam 55 contacting the magneto contact 53 to short the primary winding thereof, initial rotation of the tiller disconnects the contact 53 to permit the engine to be started by pulling on the cable 20. With the engine idling, further rotation brings the clutch cam 39 into operation to depress a vertical rod carrying a yoke 33 engaging a collar 32 on one clutch member, the cam having a protuberance designed to indicate by a click when the clutch is engaged. During this period, a circular part of the cam 54 has maintained the setting of the throttle and .the ignition constant. On continued rotation of the bar, the cam 54, through a bell crank lever 70 and link 68 rocks a lever 62 having its outer end 66 engaged in a slot 67 in an ignition control plate 45 rotatable about the engine crankshaft 21 to advance the ignition. Simultaneously, a pin 62<SP>1</SP> on the lever 62 and linked to a lever assembly 75, 76 actuates a rod 44 connected to the carburetter throttle to open it progressively with the ignition advance. In the construction shown the propeller unit is housed in a single casing 28 and a flange 13 protects the joint 9 between upper and lower parts of the engine casing 7. The power unit may be mounted inboard.

Title: Improvements in and relating to the separation of phenols
IPC: C07C37/86
Filed: 1944-06-19
Abstract: 2 : 4-Dimethyl, 6-tertiary butyl phenol is separated from mixtures containing it and 2 : 5-dimethyl, 4-tertiary butyl phenol by treating the mixture with an aqueous solution of an alkali metal and separating the insoluble 2 : 4-dimethyl, 6-tertiary butyl phenol from the aqueous layer.  The mixture may be obtained by butylating a mixture of 2 : 4-dimethyl phenol and 2 : 5-dimethyl phenol, e.g. by isobutene in the presence of sulphuric acid or phosphoric acid; and advantageously, the butylation is effected to an extent not substantially greater than that at which the percentage by weight of the total reaction product which is insoluble in the aqueous solution of a hydroxide of an alkali metal, is at a maximum, as determined by sampling of the mixture being butylated.  The 2 : 4-dimethyl, 6-tertiary butyl phenol after separation may be debutylated by known means, e.g. by heating it with a small quantity of sulphuric acid or of an aromatic sulphonic acid at a temperature of 200 DEG  C. or higher.  In an example, a mixture of 2 : 4-dimethyl phenol and 2 : 5-dimethyl phenol is treated with a gaseous mixture containing 12 per cent isobutene, 4 per cent n-butenes and 84 per cent butane, the mixture being obtained by the dehydrogenation of a mixture of butanes.  The temperature and degree of butylation are 55 DEG  C. and 65 per cent respectively.  The butylated mixture is treated with 10 per cent aqueous caustic soda solution, the insoluble oily layer is separated and steam-distilled to yield 2 : 4-dimethyl, 6-butyl phenol.

Abstract: 928,830. Railway vehicle automatic couplings. NATIONAL CASTINGS CO. March 30, 1961 [Oct. 11, 1960], No. 11689/61. Class 103(5). In a fixed jaw automatic coupler e.g. of the Willison type, it is known to move a lock 7 or 7p provided with a slot 19, Figs. 1 and 11, up and down guideway surfaces 15, 16 by means of a rotary lock lifter 8 or 8p, pivoted on a shaft 10 or 10p, which engages its cam contour with internal cam following surfaces in the lock. In the present Specification the lock lifter cam contour 33, 34 shown in full lines in Figs. 1, 6, and 10, is smoother than the cam contour (shown dotted) of known lock lifters, and has rolling contact with the cam following surfaces 38, 39 of the lock, so that the force initially exerted on the lock by the lifter 8 and as shown by the arrow in Fig. 10 is inclined to the guide surface 15 and perpendicular to the tangent 41 common to the cam and cam following surfaces instead of being directed parallel to the guide surface as in known arrangements. Moreover, the force is applied closer to the axis of the lock lifter to increase the mechanical advantage of the lock lifter, and the inclined direction given to the force not only reduces the internal frictional forces of uncoupling but rotates the lock slightly in the vertical plane to substantially reduce uncoupling starting friction with the lock of a mating coupler.
