Abstract: 1,249,498. Radar. ZELLWEGER Ltd. 12 Feb., 1969 [28 Feb., 1968], No. 7569/69. Heading H4D. A Doppler vehicle speeding radar has its horizontal beam 4, Fig. I, directed with the flow of traffic 3 at an angle a and is coupled to a camera positioned just above the beam and directed along an axis which although in the same vertical plane as the beam 4 may deviate in elevation from the horizontal. The camera is delayed from photographing a speeding vehicle 2 until it is within a " photozone " 5 parallel to beam 4. The view of the photozone 5, road edges 15, 16 vertical plane 12 of beam 4 and camera axis, and horizon 11 is as shown in Fig. 2. Since the photozone is not marked on the roadway and a lined plate fixed in front of the camera film and marked with the zone 5 would give the position of the zone varying with the inclination of the camera (Fig. 3), a template marked as Fig. 2 or with additional positioning lines 31, 32, 33, Fig. 5, is positioned on the developed photograph or superimposed on a screen projection thereof, using the centre plane line 12 and the horizon line 21 to line up with the photograph. The zone 5 then overlies the speeding vehicle. If the horizon is not visible in the photograph, line 21 can be lined up with distant objects in the photozone having the same height above ground as the camera, eg the top of the side door of a vehicle.

Abstract: 765,287. Gas-blast switches. WESTING- HOUSE ELECTRIC INTERNATIONAL .CO. March 17,1955 [March 22, 1954], No. 7821/55. Class 38(5) In a gas-blast circuit interrupter, the blast is produced by the movement of a cylinder 37 about a stationary piston 36. The cylinder carries the moving contact 19 and is moved by a lift rod 20. The blast may be directed by an insulating tubular member 43 secured to the end 39 of the cylinder and the metal parts, i.e. the cylinder and piston, may be shielded from hot arc products by an insulating shield 47 screwed on the member 43. The arc extinguishing gas may be sulphur hexafluoride, in which case the members 43, 47 would be of polytetrafluoroethylene polychlorotrifluoroethylene or polyvinyl fluoride. The piston 36 may have a non- return disc valve 53 and the cylinder 37 may have ports 42 to delay the flow of the fluid until the movement of the cylinder moves the ports above the piston. The Specification describes the interrupter in a load-break disconnect switch arrangement which is substantially that of Specification 710,925.. Specification 736,090 also is referred to.

Title: Device for indicating sparking and other disturbances in, and for automatically cutting out, transformers, choke coils and other electrical apparatus operating in an insulating medium
IPC: H01H33/55
Filed: 1925-03-24
Abstract: 250,004. Buchholz, M. March 24, 1925. Addition to 198,936. Transformers.-A device for protecting transformers and other apparatus which operate in an insulating liquid comprises a switch operated by the increase in pressure produced in the space above the liquid by gases formed by disturbances in working, the arrangement being such that no gases escape through the operation of the switch. Fig. 1 shows a form in which increase of pressure raise a cap b and trips a cut out device d. The ventilating devices g attached to the casing do not provide a quick enough escape for the gases to prevent operation. According to a modification, a monometric device is attached to the casing either above or below the liquid and serves to close contacts on increase of pressure. Fig. 4 shows a further modification in which the casing has flap valves k which open to relieve very great pressure but remain shut for the pressures required to operate the valve contact devices provided in tubes i.

Abstract: 273,017. Stephens, F. G. C., Anderson, L. J., and Cash, W. A. March 26, 1926. Pigments.-A white titanium pigment is obtained by adding boric acid or a borate such as calcium or barium borate to titanium oxide admixed with or precipitated upon an alkaline earth sulphate, and heating the mixture. The pigment may be made by treating ilmenite with sulphuric acid, filtering, diluting, adding calcium or barium sulphate, and boiling to precipitate titanium oxide upon the sulphate. The precipitate is suspended in water and neutralized by a suitable base or carbonate such as calcium carbonate, and 2-4 per cent of boric acid or calcium or barium borate is added and intimately mixed by agitation or boiling or both. Alternatively the neutralization may be offected after' the addition of the boron compound. The mixed pigment is heated at 700-900‹ C. According to the Provisional Specification titanium oxide may be employed instead of titanium oxide associated' with alkaline earth sulphate.

Title: Improvements in or relating to the separation of aromatic hydrocarbons from hydrocarbon mixtures containing the same
IPC: C10G7/08
Filed: 1944-05-04
Abstract: Aromatic hydrocarbons are continuously separated from non-aromatic hydrocarbons in mixtures of narrow boiling range by fractionally distilling the mixture in a distillation zone in the presence of acetonitrile or of propionitrile; the aromatic hydrocarbons are withdrawn as bottoms and an azeotropic mixture of non-aromatic hydrocarbons and nitrile is taken off overhead, condensed and allowed to separate into two layers.  The nitrile layer is returned as reflux to the main distillation zone and the hydrocarbon layer is passed to a secondary distillation zone from which non-aromatic hydrocarbons, free from nitrile, are withdrawn <PICT:0593463/III/1> as bottoms. Hydroformed naphtha in line 2 is admixed with acetonitrile from line 4 and introduced into column 6.  The overhead vapours are condensed in condenser 12 and allowed to separate in separator 16.  The lower (nitrile) layer is returned to the column via line 19; a portion of the upper (non-aromatic hydrocarbons) layer may also be returned via line 23.  The majority of the upper layer is introduced, through line 25, into column 27, the vapours from which are condensed in condenser 33 and then separated into two layers in separator 36.  The upper layer is returned to the secondary column as reflux, and the lower layer is supplied to the head of primary column 6 via line 41. Aromatic hydrocarbons are withdrawn from the base column 6 and non-aromatic hydrocarbons from the base of column 27.  A single condenser and separator may be used in place of the dual system, since the distillates from the two columns are roughly of the same composition.
