Title: Improvements in or relating to sundials
IPC: G04B49/02
Filed: 1925-11-07
Abstract: 264,274. Pandolfi, M. Nov. 7, 1925. Sundials.-A portable sundial is so eonstructedthat at any geographical position it may, by a simple adjustment, be adapted to give the apparent or mean solar time of that, or any other, position. A first gnomon A coacts with the hour lines marked on the dial and a second gnomon B coacts with a map also marked on the dial and covering the area within which the dial may be used correctly. In the construction' described, when the dial is horizontal and correctly orientated it is adjusted for Tremoli, 42‹ N. and 15‹ E. In this position the plumb line from the hole g in the gnomon A meets the dial at p, on the 42‹ line for latitude and on the 15‹ line for longitude marked thereon, and the plumb line from the gnomon B falls on Tremoli on the map. Passing through the point e and at right-angles to the meridian line c-e is the equinoctial line. c is the dial's centre and g, c lies along the polar axis. If the dial be taken to a place of different latitude on the same meridian, say 50‹ E., the dial is orientated as above and then rotated about the equinoctial line 8‹, the difference between the latitudes of Tremoli and the new place; the plumb-lines falling then on the correct latitude and longitude lines and map position. For a locality of different latitude and different longitude to Tremoli, say 50‹ N. and 30‹ E., the dial is first orientated and rotated 8‹ about the equinoctial line as above, and then rotated about the line g-c until the plumb line from g falls on the line corresponding to the new meridian, 30‹ E. The dial may also be so adjusted as to give the time for a longitude other than that of the place at which the dial is actually situated.

Title: Improvements in or relating to the separation and/or recovery of vanadium and aluminium compounds
IPC: C01F7/47
Filed: 1949-11-02
Abstract: Vanadium and aluminium are removed from solutions containing alkali metal chromates and aluminates and a minor proportion of alkali metal vanadates by adding a lead compound, e.g. the oxide, hydroxide, sulphate, basic sulphate, nitrate, chloride, or acetate, and simultaneously or subsequently bringing the pH to 8-9, to co-precipitate the alumina, and substantially all the vanadate ion and a little of the chromate ion as their lead salts, and removing the precipitate from the solution.  The process finds application in the extraction of chrome ores as disclosed in Specification 661,945, the "raw liquor" being treated as above described.  The alumina-lead chromate-vanadate precipitate may be discarded, or treated with sulphuric acid to produce lead sulphate and an impure aluminium sulphate solution.  Alternatively, it may be dissolved in 50 per cent caustic soda solution, and treated with sodium, calcium, barium, &c. or hydrogen sulphide to reduce the chromate and to precipitate lead sulphide.  The vanadium-containing sodium aluminate solution is purified by treatment with barium halide (chloride) or sulphate or hydroxide to precipitate a barium vanadium complex.  The chromic hydroxide-lead sulphide precipitate from the previous operation is treated with sulphuric acid to produce lead sulphate and hydrogen sulphide for reuse, and chromic sulphate solution.

Title: Improvements in and relating to the scavenging mechanism of internal combustion engines
IPC: F02G3/00
Filed: 1923-11-10
Abstract: 228,645. Still, W. J. Nov. 10, 1923. Pumps, actuating by separate motors.-Steam used to increase the power of an internal combustion engine, is afterwards employed to work a turbo-blower to provide the scavenging air of the engine. Preferably the turbine forms the third stage of expansion of a Still engine which is of compound form on its steam side. Steam, from the engine, passes through a port 4 and a pipe 5 to a group of nozzles in the low-pressure turbine B, some of which may be closed by handcontrolled valves 6, 7. As the steam pressure increases an adjustably weighted valve 2, Fig. 2, sliding in a casing 1, rises and opens ports 1<a> leading to other groups of nozzles; excessive steam pressure is relieved by a spring controlled valve 12; air cushions 10, 11 are provided from the valve 2. A high-pressure turbine A may be supplied with steam from another source and exhaust through a pipe 16 into the chamber behind the port 4; a centrifugal governor 18 cuts off the supply when the speed exceeds about 70 per cent of the normal speed; it may be thrown out of action by a lever 20 which is mounted on an eccentric bush. The two turbines A, B, and the blower D may be mounted on different shafts. To enable the high-pressure rotor to run free, a non-return valve may be provided in the pipe 16, a needle-valve controlled leak off pipe may connect the exhaust chest to vacuum. The blower shaft may be connected to an electric generator, the field of which is variable to maintain a constant voltage, the current being used to work a ship's steering motor or for a similar purpose.

Title: Improvements in or relating to tractors and working implements associated therewith
IPC: A01B63/111
Filed: 1947-10-24
Abstract: 632,884. Agricultural implements. ZBROJOVKA BRNO, NARODNI PODNIK. Oct. 24, 1947, No. 28438. Convention date, Nov. 4, 1946. [Class 6(i)] [Also in Group XXIX] An automatic depth control for the hydraulic lifting mechanism of a tractor comprises a subsidiary cylinder 23 responsive to the pressure in the main cylinder 10 and acting on a distributer 16 for the working fluid in such a way that changes in pressure in the main cylinder automatically effect lifting or lowering of the implement. The implement 1 is connected by a triangulated linkage 2, 3, 4 to upper and lower arms 5 and 6 pivoted to the tractor. The piston of the main cylinder 10 is attached to the arm 6. A conduit 11 connects the cylinder to a distributer 16 having a rotary valve 15 communicating with ports 13 and 14 leading to a pump and reservoir respectively. The valve rotated by a rack 18 and pinion 17 from a system of levers 19, 20, 28, 29 pivoted to a hand lever 35, and, at 21, to an arm 22 fixed to the arm 6. The lever 28 is pivoted at 27 to the piston 24 of a subsidiary cylinder 23 connected to the main cylinder 1Q. Manual movement of the lever 35 to the right moves the lever 20 about the pivot 21 and, by rotating the valve, puts the conduit 11 into communication with the reservoir. The implement then falls until the consequent movement of the pivot 21 rotates the valve in the opposite direction. Changes in working resistance are transmitted as increased or decreased pressure in the main cylinder and this effects movement of the spring-loaded piston 24 in the subsidiary cylinder 23. The pivot 27 is thereby moved to rotate the valve 15 in the appropriate direction.

Title: Method of making fast switching semiconductive devices with silicon nitride passivation
IPC: H01L21/322
Filed: 1970-06-12
Abstract: 1,247,329. Semi-conductor devices. WESTINGHOUSE ELECTRIC CORP. 12 June, 1970 [24 June, 1969], No. 28556/70. Heading H1K. The manufacture of a semi-conductor device includes the steps of forming a PN junction terminating beneath an oxide layer on a wafer surface, depositing silicon nitride over the oxide at a first temperature, forming a contact hole through the nitride, and then diffusing a heavy metal lifetime killer into the wafer at a second, higher, temperature. Both temperatures are above that at which heavy metal aggregates can form. In the embodiment the transistor zone configuration shown in Fig. 4 is formed in an N epitaxial layer overlying a P-type silicon substrate by planar diffusion techniques through a masking layer 20 of silica which reforms during the last diffusion. Silicon nitride 22 is next deposited at 800-900‹ C. by thermal reaction of ammonia with silane or silicon tetrachloride. Apertures 26 are then formed by etching away parts of a deposited overlayer of silica and removing the thus exposed nitride with a different etch. Gold is deposited on the back face and diffused in for 10-15 minutes at 1060‹ C. The masking oxide and that beneath the apertures is then etched off and electrodes and interconnections formed by pattern etching a vapour deposited layer of aluminium. The sequence of steps and brevity of gold diffusion prevent aggregation of the gold, or the nickel or copper which can be used instead and enable etching of the nitride to be completed before heat treatment densifies it.
