IPC: D06M14/22
Filed: 1973-10-19
Abstract: 1439977 Treating grafted cellulosic materials AGENCE NATIONALE DE VALORISATION DE LA RECHERCHE 19 Oct 1973 [27 Oct 1972] 48847/73 Heading C3G [Also in Division D1] Cellulosic textile materials are treated by (a) effecting grafting of the material with a monomer which, when formed into a polymer, has the characteristics of an elastomer at ambient temperature; (b) effecting irradiation treatment by ionizing radiation of the grafted cellulose material so as to achieve cross-linking of the grafts formed, thus leading to permanent crease resistance properties and (c) effecting post-irradiation treatment by storage enabling the cross-linking to be completed. Examples are given in which (i) cotton poplin is padded with ammoniacal ceric ammonium nitrate solution, grafted with n-butyl acrylate in vapour form, subjected to irradiation from an electron accelerator, stored and then stabilized by immersion in an aqueous bath of hydroquinone; (ii) cotton serge is padded as in (i), repadded in a solution of 2-ethylhexyl acrylate, subjected to irradiation from a Co<SP>60</SP> source, then stored and stabilized as in (i); (iii) polyester/regenerated cellulose fabric is treated as in (i) and dyed or printed; (iv) linen/polyacrylic fibre fabric is treated as in (i), with the addition of acrylonitrile as graft monomer, printed or dyed; (v) cotton is grafted, as in (ii) with 2-ethylhexyl acrylate and acrylonitrile and further treated as in (ii); (vi) linen is treated as in (i).

Also in Division H4] A backing for a piezo-electric crystal comprises a bundle of parallel wires of e.g. copper or tungsten embedded in a thermosetting or thermoplastic material. The wires may extend normally to the crystal and may make contact with an electrode thereby providing an electrical connection. To prevent reflection of mechanical energy in the backing, the wires may be splayed out, tapered (e.g. by rolling) or cut to different lengths and arranged systematically or randomly. The wires may be coated with a high-strength plastic material and clamped together at the end adjacent the crystal. The other end of the bundle may then be splayed and filled with a material giving high attenuation e.g. plastic material filled with tungsten powder. The plastic coating on the wires may be tapered in thickness towards the end of the bundle.

Title: Device for the Uniform Distribution of the Liquid to the Heating Tubes of a Downward Flow Film Evaporator
IPC: B01D1/10
Filed: 1967-11-10
Abstract: 1.196,493. Evaporators, downflow film type. WIEGAND APPARATEBAU G.m.b.H. 10 Nov., 1967 [22 Nov., 1966], No. 51200/67. Heading B1B. Liquid to be evaporated is distributed to the tubes 2 of a downflow film evaporator by means of two vessels 8, 9, one within the other, each having a perforated base, and the inner vessel 8 also having a perforated side wall. The individual perforations in the inner vessel 8 have a smaller cross-sectional area than those in the outer vessel 9, but the total cross-sectional area of perforations in vessel 8 is greater than that in vessel 9. The base of vessel 9 is perforated so that the liquid is sprayed direct into the mouths of tulbes 2, or onto the surface of tube-plate 1, as shown on the right and left-hand sides of the figure, respectively. If the liquid is hot when it enters the dome 3 through nozzle 4, some of the liquid vaporizes, and the vapour is separated from the liquid by plates 5 and 6. The liquid cascades from plate 5 onto plate 7 and into vessel 8. The vapour flows down the annular cavity between dome 3 and vessel 9, and then enters the mouths of the tubes 2. Under ordinary circumstances, a small head of liquid is formed in vessel 8 (see left-hand side of figure). If the perforations in the base of vessel 8 become blocked, a greater head of liquid builds up, and the liquid flows out of the perforations in the side wall. The distributing device may comprise more than two vessels, nested inside one another.

Title: Pipe-line for electric power transmission

Filed: 1970-10-29
Abstract: 1324552 Pipeline for electric power transmission KERNFORSCHUNGSANLAGE JULICH GmbH 29 Oct 1970 [30 Oct 1969] 51475/70 Headings H1A and A4D A pipe-line for electric power transmission at low temperatures comprises, a jacket-pipe 1 surrounding a radiation shield 2 enclosing guideducts 7 for conductors 8 and second coolant, and guide-ducts 9 for a first coolant. The gap between the jacket-pipe 1 and the shield 2 contains reflective radiation screens 3 and may be evacuated. The second coolant, e.g. liquid hydrogen, transfers heat from the conductors to the first coolant, e.g. gaseous helium, which transports the heat to refrigerating plants. A circuit of two-guide-ducts 7 and circulating pumps may be used. A third coolant contained in conduit 12 cools the radiation shield 2. For conductor access, periodically along its length the jacket-pipe 1 has portions 5, Fig. 4, of enlarged diameter at which the radiative shield 2 encloses ducts formed by partitions 13 and detachable covers 14, similar to covers 28 in the jacketpipe 1. These ducts enclosed by shield 2 and the spaces between shield 2 and jacket-pipe 1 are separated between small and large cross-section portions of the pipe-line by partitions 19 which are provided with throughways for conduits 11, 12a. The vacuum connection across the partitions 19 is made via conduits 21, 22 controllable by valves 23, 24. Access to a conductor is gained by removing the respective covers 6, 28 and 14 and loosening a pipe coupling (27), Fig. 5 (not shown) between sections of guide-ducts 7a.

Abstract: 1454402 Relative addressing SPERRY RAND CORP 8 Nov 1973 [8 Nov 1972] 51819/73 Heading G4A In a data processing system the memory addressing circuits include two state registers each storing base addresses for instructions and data, circuits arranged to select one of the state registers and to compute from supplied relative addresses and the stored base addresses, absolute addresses, there being means to perform address limit checks on computed addresses using upper and lower limits stored in registers associated with the state registers and logic circuits responsive to address limit check failures to select the previously unselected state register to cause the absolute address to be recomputed. The system is distinguished from that of German OS P23 42 101.4 in that it uses hardware circuits and operates without software intervention. The present arrangement may be used in connection with multiprogrammed, time sharing processing systems. Two processor state registers PSR, PSRU each store base addresses for instructions and data and each have an associated auxiliary register PSRU, PSRUE storing further indexing values to enlarge the available range of addresses, and a store limit register SLR, SLRU storing upper and lower relative address values for instructions and data. In operation a relative address in an instruction is added to the contents of a register specified by an instruction to form a relative address. The instruction and a control bit D11 are examined to determine whether the instruction is an executive instruction and if it is a jump instruction. On this basis one of the state registers is selected according to whether the instruction was an executive or, if not, according to the state of a further control bit D12 and successive instructions are executed as follows. The appropriate base address is added to the relative address, and the further indexing value in the appropriate auxiliary register. The associated store limit register is used to perform a check on the relative address used. If the check fails a control bit D18 is tested and, if reset, causes a further "guard" D bit to be tested. If this last bit is reset the address is used regardless of the limit check failure but if set an interrupt is signalled to cause software intervention. If however the D18 bit is set a further test is made to determine whether the instruction is a jump instruction. In either event the other state register is selected and a new absolute address is computed, the other state register being used only for the current instruction if it was not a jump instruction. If it was a jump instruction a control bit D12 is switched to cause the other state register to be used for a series of instructions up to the next jump instruction. When the other state register is selected a further limit check is performed, the address being used or not in accordance with the guard bit as above. The Specification gives details of gating logic used to perform the above operations.
