Abstract: 1,110,492. Direction indicator switches for road vehicles. BOYNE PRODUCTS, Inc. 8 March, 1966 [15 March, 1965], No. 10123/66. Heading G4Q. [Also in Division HI] A turn-indicator switch comprises a rotatable insulating body 11 carrying earthed strips 34 and 35 adapted to touch contacts 40 and 41 thereby energizing one of two self-latching relays (45 or 52, Fig. 5, not shown) which energizes the turn indicating lights. The switch is biased towards the central neutrap position by integral arms 15 and 16 bearing against fixed posts 17 and 18. The signal is cancelled when a cam 31 on the steering column earths the appropriate contact 43 or 43a after making the turn, these contacts being arranged on arms 27, 27a so that rotation of the steering column will cause one or other to be earthed according to the direction of rotation. Earthing of the appropriate contact re-energizes the coil of the self-latching relay to release it. The circuit (Fig. 5, not shown) is arranged so that a turn signal in one direction cancels a previous signal for a turn in the other direction if not already cancelled by rotation of the steering column. Headlamp switch.-The handle (20) of the turn switch is hollow and contains a spring loaded rod (60, Fig. 2, not shown) adapted to move a contact (77) into engagement with a fixed contact (76). An operating stem (71) at the tip of the lever is pressed to change the state of the switch, which may control the high beam headlights (84 and 85, Fig. 6).

Title: Resinous poly-ª--olefines and their preparation
IPC: C08F2/00
Filed: 1959-03-26
Abstract: Resinous olefin polymers are made from monomers having the general formula: CH2=CH-(CH2)nR wherein n is 1 or 2 and R is an alicyclic or unsaturated alicyclic group, containing from 5 to 9 carbon atoms. Monomers specified are various 4-alicyclic-1-butenes and 3-alicyclic-1-propenes, e.g. cyclohexyl, -pentyl and -pentadienyl derivatives.  The monomers are polymerized at 20 DEG -250 DEG C. using a catalyst comprising a Ti, Cr, V, Zr or Mo halide and an alkyl of a metal of Group I, II or III of the Periodic Table.  Catalyst components specified are titanium tri- and tetrachloride, titanium diethoxy dichloride, vanadium tetrachloride, molybdenum pentachloride, triethylaluminium, ethylmagnesium bromide, amylsodium and butyllithium.  The polymerization is preferably carried out at raised pressures and under an inert atmosphere, e.g. nitrogen, and in an inert organic solvent, e.g. pentane, hexane, heptane or higher alkanes.  The polymer may be separated after the reaction by pouring into a lower alcohol, e.g. methanol, and may be washed with acidified methanol and water.  The polymers can be dissolved, e.g. in hot tetralin, to form viscous dopes which can be spun into fibres and filaments which may be stretched and the polymers can also be extruded into sheets and films, e.g. photographic film supports, and may be moulded.  Certain polymers which contain unsaturated substituents, e.g. cyclohexenyl, cyclopentenyl or cyclopentadienyl groups can be obtained in rubbery form, especially by using a dialkoxy titanium dichloride as a catalyst component, and these may then be cross-linked.

Title: Improvements in or relating to a process and plant for the treatment of sewage and the like
IPC: C02F3/04
Filed: 1940-06-18
Abstract: 542,008. Filters. COOMBS, J. A. June 18, 1940, No. 10505. [Class 46] Sewage or other impure liquid to which activated sludge has been added is forced through a filter bed comprising filtering media in the form of balls and through which the passage of air is promoted. The activated sludge may be that obtained from a sewage treatment plant as described in Specification 514,627 and the process is applicable for the treatment of partially purified effluent from such a plant. The balls may have pitted surfaces and may be of stone, concrete, brick, synthetic resin or similar mouldable material. The plant shown in Fig. 1 has two filter beds 10, 11 through which the liquid passes successively, the bed 10 serving to flocculate impurities and the bed 11 to mitrify them. The beds are supported on false floors 14 of perforated and corrugated sheeting or tiles and comprise alternate layers of coarser and finer media, the lowest and coarsest consisting of balls having a diameter roughly equal to the pitch of the corrugations. Impure liquid and activated sludge are distributed over the bed 10 by a travelling distributer 27, drawing siphonically from a trough 25 to which they are supplied through pipes 24, 24a respectively. Filtrate from the bed 10 passes to a well 32 to which activated sludge is supplied through an inlet 33. The liquid is raised from the well to a trough 35 by an air lift and distributed thence over the filter 11. Pipes 41 opening below the floors 14 may be connected to suction pumps and blowers for drawing atmospheric air downwardly through the beds or for passing air, which may have been dried and heated to a temperature of 100‹ to 150‹F. as described in Specification 521,895, upwardly through the beds. In the latter case the air pressure may be automatically regulated according to the amount of sludge accumulated in the upper portion of the bed. The beds may be in a concrete structure sunk below ground level with runways for bringing and removing the media. To facilitate removal of the bed a gantry ,40 carrying a mechanical labourer or elevator as described in Specifications 496,637 and 521,939, [Group XXX], may extend across the beds. As shown in Fig. 3, the filtrate from the bed 10 before distribution over the bed 11 is passed through an intermediate filter in the form of an endless travelling mat 46. The filtrate from the upper run of the mat collects in a sump 47 and is passed by a pipe 48 to the bed 11. Sludge removed from the mat by a brush 49 and by air blown through perforations in a hollow shaft 50 is collected in a sump 51 and discharged by a worm conveyer to trucks 52, Modified plant is described which comprises a tank in which sludge, removed from the sump below the front filter by scrapers as described in Specification 514,662, is activated under pressure for use in the plant. It is stated that the plant may be mounted on a movable carriage.

Abstract: 490,252. Implements and machines for working land. MURRAY, J. B. April 13, 1937, No. 10522. [Class 6 (i)] A tilling-machine adapted to be drawn by a tractor is supported by a single pair of land wheels 14 and is provided with rotary implements 17 on a transverse shaft so disposed as to give little more than a working clearance between the implements 17 and the land wheels or land wheel axle. The implements are driven by the engine 11 of the tractor only the rear part of which is shown. The frame of the tilling machine carries on opposite sides a gear case 20 and a plate 21 in which the tool shaft 16 is journalled and which are connected at their upper ends by tubes 23 carrying a gear box 24 between them. The tubes 23 enclose a shaft which is chain geared to the tool shaft 16 and which is rotated from the tractor engine through universal couplings 26, 27. A clutch 25a is provided between the coupling 26 and gear box 24. The working depth of the tools can be adjusted or the tools raised clear of the ground by rotating spindles 30 provided on each side of the machine. The spindles actuate sliding blocks 28 in which the axle of the land wheels is journalled. As shown in Fig. 2 the tubes 23 are of different lengths so that when the machine is drawn by a centredrive tractor as shown one of the land wheels 14 follows in the track of one of the tractor wheels, the other land wheel being outside the track of the other tractor wheel. By reversing the positions of the tubes 23 and moving the gear box the driving rod can be brought into the position 32 for use with a tractor of the side drive type. The tools 17 are fixed to the shaft 16 by bolts passing through flanges 35 on the shaft which may be provided with a series of apertures to enable the tools to be fixed in any position. A guard 33 is mounted over the tools and carries a series of pivoted spring tines 34 which can be adjusted in position by a handle 34b and rack 34c. In a modification the distance between the land wheels 14 is less than the overall length of the series of tools on the shaft 16 and the tips of the tools just clear the peripheries of the land wheels. Fig. 4 shows another method of mounting the land wheel axle to enable it to be raised and lowered. The axle 15 is journalled in a member 37 which has a series of teeth 38 engaging the teeth of racks 40 one of which is fixed to the machine frame, the other being pivoted at 41 and movable by a handle 43. The handle can be fixed in any position by a spring detent 44.

Title: Improvements in and relating to the manufacture of semiconductor devices
IPC: H01L21/00
Filed: 1961-03-23
Abstract: After subjecting a germanium semi-conductor wafer, having indium or indium alloy electrodes, to a clean-up etch, hydrogen peroxide is directed over the wafer and electrode surfaces while a film of etchant still adheres thereto. A transistor 11 is electrolytically etched in potassium hydroxide solution and is immediately placed under nozzle 12 from which issue drops 10 of hydrogen peroxide.  The wafer is arranged so that each drop is split by the wafer edge, and a major portion 17 rolls over collector electrode 18 and a smaller portion 19 over emitter electrode 20.  The film of etchant still remaining on the wafer catalyses the release of oxygen from the peroxide for the formation of a protective layer of germanium oxides on the wafer, and simultaneously the drop rinses the wafer surfaces. After the application of about five drops of peroxide a nitrogen blast is directed over the surface to dry it.  The application of peroxide and the gas blast may be repeated several times, and between each rinsing cycle, or after completion of the rinsing process the carrier 14 and base tab 13 are rinsed in warm or hot water, and <PICT:0969969/C6-C7/1> <PICT:0969969/C6-C7/2> dried by nitrogen.
