Abstract: 1,167,648. Vehicle suspensions. MOULTON DEVELOPMENTS Ltd. 17 June, 1968 [17 March, 1967], No. 12705/67. Heading B7D. [Also in Divisions F1 and F2] A vehicle suspension comprises a diaphragmtype hydraulic displacer unit acting between each wheel and the sprung structure, liquid displaced from which being carried by means of an hydraulically hard pipe to and from a plurality of hydraulic accumulator springs operating in parallel, one of which has a chamber having a resilient wall composed at least in part by a rigid metal member which when free is movable in response to increase or decrease in the volume of the fluid filled chamber, and there are provided means which can be actuated to render the metal member immovable and to limit the volume of the fluid-filled chamber, the displaced fluid being utilized to alter the pressure of the liquid in the system and hence altering the height of the sprung structure of the vehicle in relation to the associated wheel. As shown, Fig. 1, a pair of hydraulic displacer units 10, acting between suspension arms 1, 2 and the vehicle structure are connected by means of an hydraulically hard pipe 17, through damper valves 23 to a series of accumulator springs each comprising a cylinder 19, a movable wall 20 and a spring 21, in parallel with each other and a supplementary accumulator 30 of similar construction, in conjunction with which is an electrically operated screw-jack 40 which has an extensible strut 41 which may be brought to bear against the wall 32 to cause it to adopt position B, expelling fluid from the spring, and to render the wall immovable. In a modification, Fig. 3, the hydraulic accumulator comprises a housing 50 having a conically tapering part 51, a frusto-conical cup-shaped metal member 52 and a rubber annular spring 53 bonded to the cup-shaped member 52 and housing 51, In a further modification, a single hydraulic actuating device may be arranged to operate simultaneously on the metal members of two eupplementary hydraulic accumulator springs respectively associated with the suspensions of corresponding wheels on opposite sides of the vehicle.

Patent GB-484136-A (GB)
Title: Improvements in or relating to methods for the production of pure magnesium compounds, more particularly magnesium oxide
IPC: C01F5/00
Filed: 1937-05-06
Abstract: In the extraction of magnesite and like minerals with acids such as hydrochloric or nitric acid, the acid is caused to act on lumps of the raw material in a gaseous state in the presence of steam at elevated temperatures of the order of 100-500 DEG  C., whereby highly concentrated solutions or aqueous melts of the salts extracted are obtained.  Hydrogen and chlorine may be directly combined adjacent the apparatus and the heat of formation of the hydrochloric acid be thus utilized; the acid preferably carries sufficient free chlorine to oxidize iron and manganese present in the raw material. Decomposition may be effected in a tower, the lye collecting at the base of the tower being recirculated if desired to increase its concentration.  From the solution of magnesium chloride finally obtained, impurities can be removed by caustic magnesite, calcium compounds by addition of sulphates or sulphuric acid, and pure magnesium chloride be then crystallized out.  The crystals may first be heated, if desired in vacuo, to produce the tetrahydrate, and then be decomposed at 300-1000 DEG  C. with superheated steam to obtain magnesium oxide and recover hydrochloric acid for re-use.  The Specification as open to inspection under Sect. 91, comprises also the following subject-matter: the removal of calcium from magnesium chloride solution by addition of sulphates or sulphuric acid, the solution having a specific gravity of at least 1,35 and the temperature being at least 70 DEG  C.; the decomposition of magnesium chloride in a shaft furnace with superheated steam passed in at the base of the shaft; and the decomposition of calcined dolomite or magnesite by acting on a water suspension thereof with liquid or gaseous acid supplied at such a rate and in such quantity that only the calcium is dissolved.  In the last case, a tank containing the suspension may have supported therein an open-ended tube into which the gaseous acid, which may be nitric acid, is passed.  This subject-matter does not appear in the Specification as accepted.

Filed: 1962-04-05
Abstract: <PICT:0999296/C1/1> Doped semi-conductor material is prepared by deposition on to the same semi-conductor material from a mixture of a gaseous compound of the semi-conductor, the dopant and a carrier gas, part of the stream of carrier gas being diverted before mixing with the semi-conductor compound, to pass over the doping material in solid form.  In the Figure, part of the hydrogen stream from source 9 is passed over solid phosphorus pentachloride in chamber 10 maintained at a constant temperature by bath 11.  Another part of the hydrogen stream is passed through a thermally decomposable source 6 of silicon such as silico-chloroform, and the two streams are reassociated and passed into reaction chamber 20 which contains electrically heated silicon rods 24 upon which silicon containing phosphorus is deposited.

Abstract: 131,422. Comstock, D. F. Aug. 15, 1918. Optical systems.-Relates to a compound lens system for obtaining in the same plane two or more complemental images, i.e. images in different colours, and such that when superposed they produce an accurate colour picture. A positive lens component such as shown in Fig. 1 is combined with a prism system of optically dense medium and comprising a reflecting-transmitting surface G, the lens system having substantial aberrations which are neutralized by the prism system so as to form a corrected system giving (with the aid of colour screens GS, RS) images GI, RI. The back faces of the prisms may be curved in different degrees; or the lengths of the paths of the two ray-systems may be made unequal; constructions presenting these features are shown in Figs, 2 and 3 respectively. The lens component shown in Fig. 1 comprises four lenses separated by a diaphragm d into two groups of two lenses each, the forward group having a pair of facing surfaces of negative power and the rear group having a cemented surface of positive power. The lens component shown in Fig. 2 comprises two groups of lenses, separated by an air space of positive meniscus form; the forward group comprises a positive lens L<5> and a negative lens L<6> ; and the rearward group comprises a negative lens L', a positive lens L<8>, and a positive lens L<9>. The positive lenses L<5> and L<8> are of highly-refractive baryta-crown glass; the negative lenses L<6> and L' are of low refractive glass The lens component shown in Fig. 3 comprises a group of four lenses L<13> - - L<16> similar to the arrangement of Fig. 1 and a forward group of lenses L<10>, L<11>, and L<12> ; the two latter form a cemented doublet of practically infinite focal length and L<10> is a protecting plate of uniform thickness for the lens L<11>. The focal lengths of the two elements of the doublet are substantially equal for D-lightand the internal nodal points lie close together, thus making a substantially non-magnifying element.
