Title: Improvements in or relating to filter plants
IPC: B01D29/00
Filed: 1954-05-18
Abstract: 760,272. Filters. NORSK HYDROELEKTRISK KVAELSTOFAKTIESLSKAB. May 18, 1954 [May 19, 1953], No. 14615/54. Class 46. A two-way valve A is moved over from the position shown by a time-controlled device. A container G is thus connected to the atmosphere, and liquid from column K and from a filtrate pipe F flow along pipe H into G until the level therein reaches that of an overflow P from a liquid trap J. A level-sensitive device in G causes reversal of a valve B (from the position shown) when this level is reached, the pressures on both sides of the valve B being then equal. (Pipes K and L are connected to a common vacuum source V). Thereafter the liquid in pipes K, H, and container G comes to rest while filtrate flows out at P. A time-controlled device causes return of valve B when the sludge layer on filters E reaches a desired thickness, and the device controlling valve A returns that valve to the position shown immediately afterwards. Compressed air from a pressure maintained reservoir N now flows into container G, and when the liquid level therein is forced below the level of overflow P liquid is forced along pipe H, through valve B, along pipe F and back through the filters E. The time during which air pressure is exerted on the liquid in the container G is sufficient for the sludge cakes to be loosened from the filter cloths and to fall to the bottom of the thickener D. Valve A is then reversed and the cycle is repeated. In a modification, Fig. 2 (not shown), the container D is a closed pressure-container on a level with the container G, and it is supplied with liquid to be filtered from an elevated tank containing liquid at atmospheric pressure. The trap J is dispensed with, and pipes K and L communicate with the atmosphere.

In examples, di-o-tolylamine reacts with diethylaminoethyl chloride, b -dimethylaminopropyl chloride, g -dimethylaminopropyl chloride, and many other dialkylaminoalkyl halides to give the corresponding N-(b -diethylaminoethyl-) and other N-dialkylamino-alkyldi-o-tolylamines; N-o-tolyl aniline reacts with g -piperidinopropylchloride and dialkylaminoalkyl halides to give the corresponding N-(g -piperidinopropyl) N-o-tolylaniline and dialkylaminoalkyl-o-tolylaniline.  The invention also comprises the salts and quaternary salts of the above amines resulting from the addition of alkyl esters or mineral or organic acids in the customary manner.  In an example, N-di-methylaminoethyl di-o-tolylamine is converted to the trimethylammonium iodide with methyl iodide.  A list of substituted diarylaminoalkylene dialkylamines, and heterocyclic substituted products is included.  Other substituted amino alkyl halides which may react with the diarylamines include pyrrolidinoethyl chloride, and other dialkyl aminoalkyl halides including the bromides and iodides.

Title: Improvement in method for the conversion of conical projections to orthographic projections
IPC: G01C11/00
Filed: 1926-06-18
Abstract: 254,301. Brock & Weymouth, Inc., (Assignees of Brock, N. H.). June 23, 1925, [Convention date]. Photographic surveying.-Comprises a method of converting the conical projection of an aerial photographic view into the orthogonal projection of a map. A series of contoured plates A<1> of the view and also a geometrically constructed traverse in orthographic projection of selected points in the successive views is prepared, such points including the optical centres of the views C<1> - - C
. Each plate A<1> is then successively mounted in a projection apparatus T and the image projected on to the traverse drawing supported on a table J, Fig. 7, by a lens K and reflecting prism L, with the aid of a lamp P<3>. The projected optical centre is brought into coincidence with its plotted position on the traverse drawing, which is then turned so that a line joining this centre with a selected point coincides with the projection of the line. The projected image and the plate A<1> are then adjusted in relative position until the scale of the projected line is correct. The contour line through the selected part is then traced on the drawing, and the plate readjusted for each contour line. This adjustment is effected automatically. The projector T is mounted on a support N carried by rollers N<2> on wedge pieces O. The support M<1> for the table J has a guideway in which a slide Q moves vertically, the slide carrying a pivoted sleeve Q<2> through which passes a rod R, fulcrumed at R', and passing through a pivoted sleeve S<1> on the projector T. Movement of the wedge-piece 0 lowers or raises the lens K and automatically adjusts the position of the plate A<1> to enable a fresh contour line to be drawn to the correct scale. By thus tracing all the contour lines on the whole series of contoured plates a correct orthographic projection of the territory is obtained on the traverse drawing.

Title: Improvements in or relating to electric ignition apparatus for internal combustion engines
IPC: F02P7/073
Filed: 1956-05-17
Abstract: 789,949. Ignition systems. SIEMENSSCHUCKERTWERKE AKT.-GES. May 17, 1956 [May 17, 1955], No. 15457/56. Class 7(4) The primary winding of the ignition system is associated with a semi-conductor device of junction type the latter being influenced directly or indirectly by a source of radiation, the effect of which on the device can be varied. In Fig. 1 the current in the primary 2 of the ignition coil is controlled by a photo transistor 13. Thus when the shutter 17 masks the transistor from a lamp 14 which is associated with a condenser lens 16 the resistance of the transistor rises and an ignition spark occurs. In place of the lamp a heating winding may be employed on a radio-active preparation. Electron radiators of small range are particularly suitable. In place of the photo transistor a photo diode may be employed. In Fig. 2 a transistor 24 is in series with a resistor 22 and a voltage is applied to the transistor except when radiation from the source 18 is interrupted. On interruption of the radiation the transistor blocks the circuit. The invention is applicable to magneto ignition systems. It is stated that the distributer may be replaced by a number of semi conductor resistances controlled by radiation. The shutter may be rotated by a shaft 11 which may be driven off the shaft of the engine. Longitudinal shutter movements are possible and in some cases the lower edge of the piston may be employed as the shutter. For influencing the semi conductor device α # or Á radiation may be employed.
