Abstract: 1,228,540. Malonic acid dinitrile. LONZA Ltd. 30 Oct., 1969 [20 June, 1969], No. 53174/69. Addition to 1,222,343. Heading C2C. ' Malonic acid dinitrile is produced by reacting acetonitrile and cyanogen chloride in the gas phase at from 780‹ to 1200‹ C., the reactants being passed through a reactor at such a rate that they flow in the range between laminar flow and turbulent flow or in the range of turbulent flow, to give a reaction product comprising malonic acid dinitrile contaminated by maleic acid dinitrile and fumaric acid dinitrile, immediately cooling the reaction product to a temperature of from 20‹ to 50‹ C., and removing the maleic acid dinitrile and fumaric acid dinitrile, either by reacting them with a compound having at least two conjugated double bonds to give corresponding Diels-Alder adducts which are separated, or by selective hydrogenation with a calculated quantity of hydrogen in the presence of a hydrogenation catalyst to give succinic acid dinitrile which is separated by fractionation.

Abstract: 1,229,880. Hydraulic shock absorbers. OLEO INTERNATIONAL HOLDINGS Ltd. 8 Jan., 1969 [23 Jan., 1968; 30 May, 1968], Nos. 59636/68 and 25687/68. Heading F2S. A valve for providing, in an hydraulic shock absorber, a damping-force (R) to fluid-velocity (V) characteristic of the form shown as A + B in Fig. 8, consists of a composite valve member 42-43, Fig. 2, which is spring biased toward a liquid outlet 37. The valve provides a flow path passing in series through an orifice 45 in the inner valve element 43 and an annular gap 46 between the elements 42 and 43. In parallel with these is a flow path which is closed until sufficient fluid pressure has built up to move the complete valve member against its spring 44 and so displace the valve surface 41 from the outlet 37. At low flow velocities only the series path is open and the orifice 45 (whose characteristic is A in Fig. 8) is less restricted than the gap 46. At higher flow velocities, relative axial separation of the two valve elements progressively lessens the resistance of the gap 46 (whose characteristic is B). The combined effect is the substantially linear characteristic A+B of Fig. 8. At higher velocities, the parallel flow path opens and the resistance to flow will not increase further-hence the horizontal (" cutoff ") portion of the overall characteristic as shown in Fig. 8. Varying the spring bias, by rotating screw 48, can make the overall characteristic correspond to the A+C curve in Fig. 8. In the shock absorber of Fig. 1 (not shown), a piston is contained in the inner one of three concentric tubes so interconnected by ports that both directions of piston movement result in flow of fluid in the same direction between the innermost and outermost tubes. The valve of Fig. 2 is interposed in this flow path, the valve's longitudinal axis (left to right in Fig. 2) being disposed perpendicular to the shock absorber axis and tangential to an imaginary cylinder situated in the annular gap between the outermost tube and the intermediate tube of the shock absorber. Figs. 3 to 6 (not shown) depict modifications of the Fig. 2 valve, in which (a) the elements corresponding to 41 and 43 of Fig. 2 have conical interengagement; (b) the screw 48 of Fig. 2 is replaced by a rolling diaphragm fluid displacer. The latter is designed to be operated by a compressed air supply in a vehicle in whose suspension system the valved shock absorber is incorporated.

[Also in Division B5] Laminates are bonded with a polyimide P. In two examples (4a) and (4b), 8 layers of glasscloth impregnated with 43% P are piled up and placed between the plates of a press heated at (4a) 120 C., (4b) 250 C., 3 mm. apart, and maintained at this temperature for 5 minutes. 14 Bars pressure is then applied which the temperature is held at (4a) 300 C., (4b) 350 C. for (4a) 30 minutes (4b) 3 hrs., and during subsequent cooling. The resultant laminate is a translucent light-yellow with thickness (4a) 1À5 mm. (4b) 1À7 mm. containing (4a) 20% (4b) 25% by volume of resin and (4a) 13À3% (4b) 10À5% by volume of pores. Its specific gravity is (4a) 1À91 (4b) 1À86, and it withstands (4a) 75À9 hectobars (4b) 69À5 hectobars in flexion tests at room temperature. In Example (5) Ti -ribbons 102À4 x 25À4 Î 1À6 mm. are degreased with trichloroethylene and dried, and are then immersed in an aqueous soln. of HCl, HF, and H 3 PO 4 , washed with tap-water, and dried at 90 C. To a solution of P is added Al powder and arsenic thioarsenate, the mixture being finely ground. The resulting composition C is then used to impregnate glass-cloth sheets sufficient to give a material of 400 g./m.<SP>2</SP> wt.; each sheet is dried at 110 C. The ends of the ribbons are painted on one face with 2 coatings of C. The coated ribbons are then joined over an area of 12À7 mm. An impregnated cloth 22À7 Î 35 mm. is then placed between the two ribbons leaving 5 mm. free next to the joined section. The assembly is stuck by treatment at 325 C. and 5 bars for 1¢ hrs., followed by reheating to 300 C. for 8 hrs. and 325 C. for 5 hrs. Polyimide P is made by reacting m-phenylenebis(4 - hydroxy methylenephthalic acid) ester(s) E with diamine D H 2 N-M-NH 2 ; R and R<SP>1</SP> are hydrocarbon radicals, or R<SP>1</SP> may be H; M is aliphatic, alicyclic, aromatic, alkylaromatic, carbocyclic, or heterocyclic. The reaction may be started with the fused monomers at 150- 400 C., or with the monomers dissolved in a polar solvent S at 150-250 C. The reaction may be conducted under pressure. The reaction may be terminated at 200-400 C. If the reaction is performed at 100-220 C. until a 0À5% wt. soln. of P in N-methylpyrrolidone has # at 30 C. of 0À06-0À70, the P will be in the form of a prepolymer Q. Low M.W. ester-amides F may be formed as intermediates by heating diamine D and ester E to 200-300 C. and interrupting heating before # reaches 0À7. F is transformed to polyimide P by heating to 200-400 C. Many diamines D are specified. In particular, M may. be e.g. -R 5 -X-R 6 -, where R 5  and R 6  are aromatic or cycloaliphatic radicals and X is a single bond or -C n H 2n- , -[C(A) 2 ] n -, -(CF 2 ) n -, -CO-, -COO-, -CONH-, -O-, -S-, -SO-, -SO 2 -, -NH-, -NA-, -Si(AB)-, -O-Si(AB)-O-, -P(A)(O)-, or where n = 1-3 and A and B are alkyl or aryl. Ester E and diamine D may be reacted in stoichiometric amounts, or 105-150 moles D may be used per 100 moles E.

The island region may be formed from an epitaxial layer 6 and include a buried region 7. The second region 16 prevents minority carriers produced in the island region, by temporary forward biasing of the collector-base junction 15, from reaching the substrate region, and hence reduces the effect of parasitic lateral transistor 9, 6, 5. The spacing of regions 9 and 16 is required to be greater than the width of the depletion layer of the junction 5 but less than the diffusion length of the minority carriers in region 6. Efficiency may be improved by connecting region 16 directly to the island region 6 by contact 11.
