IPC: A01C11/02
Filed: 1935-04-01
Abstract: 454,387. Transplanting implements. BOMFORD, D. R., BOMFORD, E. R., and WILLANS, J., Pitchill, Evesham, Worcestershire. April 1, 1935, No. 10030. [Class 6 (i)] An implement for use in transplanting cabbage plants &c. comprises a frame or chassis, a channel-shaped furrow-forming share, two inclined wheels for replacing and consolidating the soil in the furrow around the plants after they have been deposited by hand, means for adjusting the share and wheels, and curved plates for moving soil into the furrow immediately the plants have been placed in position. The chassis comprises longitudinal bars 4, 5, transverse bars 6, 7, 8, and coupling members 9, 10. The channel-shaped share 11 has sides which converge inwardly and downwardly and rearwardly. It is pivoted about bolts 12 at its front end and adjustably supported by screwed rods 11<b> and nuts 11<c> at its rear end. The plants are placed in position in the furrow by attendants sitting on one or more seats 15. Soil is immediately placed around their roots by curved blades 13 preferably pivoted about the bolts 12. The inclined wheels 14 are mounted at some distance behind the share 11 on an axle 16 bent upwardly towards the middle. The wheels are adjustable along the axle 16 and the latter may be turned in its bearings to adjust the inclination of the wheels to bring the rear parts of their peripheries nearer together or wider apart than the front parts. The axle 16 is adjusted by means of an eye-bolt 20 and nuts 22 engaging a bracket 21.

Title: Improvements in and relating to semi-conductor devices
Inventor: TURNER PETER ARTHUR
IPC: H01L21/00
Filed: 1962-03-16
Abstract: 1,017,336. Semi-conductor devices. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 20, 1963 [March 16, 1962], No. 10277/62. Heading H1K. A semi-conductor device comprises a body with a planar diffused junction extending to the periphery the surface at which tapers off at an angle not greater than 30 degrees. Shaping of the semi-conductor body may be affected by apparatus as shown in Fig. 4 in which a plurality of circular semi-conductor wafers 7, 8, 9, each comprising planar PN junctions are clamped between polythene blocks 3, 4, 5 and then oscillated or gyrated in a mixture of nitric and hydrofluoric acids. The process results in the exposed edges of the wafers being etched away to leave a portion with an inclined surface. A cylinder 11 may be used to line up the wafers and blocks before clamping. If a single junction with etching on one surface only is desired the blocks may be arranged to screen the whole of the opposing surface.

Abstract: 1464214 Hydraulic boosters BENDIX CORP 12 March 1975 [1 April 1974] 10314/75 Heading F2F A check valve 90 which permits fluid flow only from a pressure chamber 52 to a fluid inlet 14 is provided to reduce instability of a spool valve 50 in an hydraulic booster further comprising a housing 12 with a fluid outlet 18, an output piston 28 responsive to the fluid pressure in the chamber 52 and a driver actuated valve operating rod 32 for moving the valve spool from a first position (shown) in which the chamber 52 is vented to a second position while communicating successively higher pressure to the chamber 52 as it is moved. As shown the valve is movable, through a sleeve 54 and a lever 44 pivoted at 42, 48 and 56 respectively to the piston 28, a spring loaded bracket 36 on the rod 32 and the sleeve 54, to the left when the lands 74 and 86 close off the venting outlet 18 from the groove 78 and the passage 80 in the spool and the land 74 provides an increasing passage between the inlet groove 72 and the groove 78 to increase the pressure in the chamber 52 to move the piston 28 and output rod 30. On failure of boost pressure the rod 32 actuates the piston 28 directly, the sleeve 54 sliding against the urge of spring 58 to close off bores 60 to the passage 80 so that if the boost pressure suddenly increases (as by release of a "sticky" valve) the chamber 52 is not pressurized suddenly, and the bracket 36 sliding on the rod 32. Feel is provided by the pressure of the chamber 52 acting on the left hand end of the rod 32, a non- sealing anti-friction ring surrounding this end.

Title: Improved apparatus for the production of metal oxides
IPC: C01G21/02
Filed: 1957-04-05
Abstract: An apparatus for the production of oxides of metals having a melting point not above <PICT:0853412/III/1> <PICT:0853412/III/2> <PICT:0853412/III/3> 500 DEG C. comprises a first chamber and a second chamber, which are solids of revolution about a common axis, and which communicate by means of an axial orifice.  The second chamber is of reduced height in its central part, and is of smaller peripheral height and larger radius of revolution than the maximum height and largest radius of revolution of the first chamber.  A nozzle for introducing molten metal to be atomized opens tangentially into the first chamber, and a nozzle for introducing the oxidising gas opens tangentially into the second chamber.  The second chamber has an axial outlet orifice.  In the production of lead oxides, the lead is first melted in a suitable atmosphere such as nitrogen, led to the atomizer, and oxidised in the oxidising chamber by any suitable oxidising gas, such as dry or damp air, which may be oxygen enriched.  The issuing oxidised lead may be further oxidised by passing it through a heater.  Figs. 1 and 2 are views of one apparatus, in which 1 is the atomizing chamber, 2 p  is the inlet for the molten metal, 3 is the entrance to the oxidising chamber 5, 4 is the oxidising gas inlets which may be heated, and 6 is the exit for the product.  The apparatus may be constructed of stainless steel. Fig. 5 illustrates an assembly in which the atomizing and oxidising chambers are indicated generally at 10, 14 is the oven to melt the metal, and 15 is the electric oven to adjust the temperature of the molten metal.  An inert or oxidising gas is introduced via duct 12 to force the molten metal into the atomizer.
