Title: Improvements in or relating to pipe end fittings primarily intended for connection to synthetic plastic pipes
Inventor: MOSELY ARTHUR COLIN
IPC: F16L19/08
Filed: 1958-11-21
Abstract: 895,461. Pipe couplings. COMPRESSION JOINTS Ltd. Feb. 15, 1960 [Nov. 21, 1958], No. 37458/58. Class 99(1). A pipe end fitting comprises male and female elements 6, 7 of a synthetic plastic capable of screw-threaded inter-engagement to define a cavity therebetween a sleeve 10 of synthetic plastic having a frusto-conical nose which, when the sleeve is mounted about the pipe 13 and located within the cavity with the said nose convergent towards the pipe end, coacts in wedge-like manner with a compression face 8 forming part of the wall of the cavity to seal the pipe with respect to the fitting, and a locking washer 11 which when mounted about the pipe and located within the cavity on the opposite side of the sleeve to the pipe end is caused to bite into the periphery of the pipe to resist axial movement of the pipe with respect to the fitting as the seal is made by compression of the sleeve and washer between opposite walls 8, 9 of the cavity during tightening of the elements 6, 7. As shown, the sleeve of nylon, has a wedge-like nose portion 15 and a recess 17 of frusto-conical from which receives the washer 11. The latter is a metal annulus having resilient radial, forwardly projecting teeth 18. In modifications, the sleeve has an end face 17, of outwardly convergent frusto-conical form, the washer being of complementary shape, or a radial end face, the teeth of the washer being bowed and flattened during assembly of the coupling. The washer may be captive on the sleeve.

Title: Process for producing lipopolysaccharides and compositions containing the same
IPC: G01N33/487
Filed: 1959-11-09
Abstract: Lipopolysaccharides are obtained by cultivating Aerobacter aerogenes in an aqueous nutrient medium under submerged aerobic conditions until rapidly growing cells are obtained, and then removing the cells from the medium and recovering lipopolysaccharide from the isolated cells.  In an example Aerobacter aerogenes cells made from experimental tank lysine fermentations are mechanically agitated, dissolved in water rendered alkaline with KOH and then are incubated at 37 DEG  C. in a trypsin medium.  The medium is then centrifuged and the resulting solid is treated with 90% phenol and the aqueous layer separated and subsequently dialyzed through polythene.  The dialyzed aqueous medium is treated with aqueous sodium acetate and then absolute alcohol.  After centrifuging the sediment is withdrawn and after further purification a lipopolysaccharide fraction having an analysis of 3,25% nitrogen, 2,54% phosphorus and 17,8% glucose is obtained.  The lipopolysaccharides stimulate the reticuloendothelial phagocytic function and are useful as a prophylaxis against fatal doses of Staphylococous aureus and Pseudomonas fluorescens.  The lipopylsaccharides may be used in conjunction with corticosteroids (see Group VI).ALSO:Lipopolysaccharides obtained by cultivating Aerobacter aerogenes in an aqueous nutrient medium under submerged aerobic conditions until rapidly growing cells are obtained, and then removing the cells from the medium and recovering lipopolysaccharide from the isolated cells (see Group IV (a)) are used either alone or in admixture as a medicine for oral, intramuscular, subcataneous, intravenous or intraperitoneal administration.  The lipopolysaccharides stimulate the reticulo-endothelial phagocytic function and are useful as a prophylaxis against fatal doses of Staphylococcus auereus and Pseudomonas fluorescens.  The lipopolysaccharides may be used in conjunction with corticosteroids such as cortisone, hydrocortisone, 9a -fluorohydrocortisone, prednisone, prednisolone, 6-a -methylprednisone, 6-a -methylprednisolone, 9-a -fluoro-16-a -hydroxy-hydrocortisone, 9 - a - fluoro - 16 - a  - methylhydrocortisone, 9 - fluoro - 16 - b  - methylhydrocortisone ACTH or a 21-lower acyl ester thereof.  In specific examples from 0.005 to 0.01% of the lipopolysaccharide is mixed with a corticosteroid and conventional pharmaceutical adjuvants.  Other substances which may be added include penicillin, streptomycin, tetracycline, oxytetracycline, chlorotetracycline, oleandomycin and tri-acetyloleandomycin.

Title: Methods of and apparatus for testing core memories
IPC: G11C11/06
Filed: 1966-08-24
Abstract: 1,107,269. Circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. 24 Aug., 1966 [2 Sept., 1965], No. 37917/66. Heading H3B. Each location in a magnetic storage matrix is tested in turn by writing and reading cycles during which the read out data is compared for parity with standard input data, and, as repeated tests take place throughout the matrix, the drive voltages applied to the combined X and Y drive lines and the Z inhibit line from supplies 44, 46 are varied sinusoidally and rela. tively slowly at slightly different frequencies. The standard and read-out data are combined at a comparator 32, the output of which causes either a pen recorder 12 or a C.R.O. to produce a trace when an error signal E from a latch 34 is applied through a logic circuit 36. This trace persists until such time as an output S indicating the completion of a test cycle of all the locations of the store is obtained without an error signal E occurring in the test cycle. The recorder 12 produces a trace determined by X/Y drive voltage and Z drive voltage co-ordinates, and since the two sinusoidal voltage variations are of slightly different frequency the trace is in the form of a Lissajous figure, Fig. 6. The trace pattern is obtained only for those coordinate voltage values which produce an error signal, and the absence of a trace in the central region of the pattern defines an error free operating area from which suitable operational voltage parameters for the store under test may be determined. The standard data is read in through a data register 16, and high speed scanning of the store is effected by a Y address counter 22 which steps an X address counter at the completion of each cycle. The sinusoidal drive voltage variations are obtained from mechanically driven sine potentiometers, Figs. 3 and 4 (not shown), the drive gear ratio of the two potentiometers being different.

Abstract: 1,254,622. Modulating light. INTERNATIONAL BUSINESS MACHINES CORP. 30 July, 1969 [19 Aug., 1968], No. 38208/69. Headings H4F and H4T. [Also in Division G1] The amplitude of an electrical signal fed from a source 11 to a transmission line structure 7 is sampled by passing linearly polarized light pulses, e.g. from a mode locked or modulated laser 1, through an electro-optic element 5 contained in the structure 7, the group velocity of the light pulses through the element 5 and the parallel component of the phase velocity of the electric signal along the structure 7 being made equal, and analysing the state of polarization of the emergent light pulses by an analyser 15 and photo-cell 17. The spatial extent of the pulses in the medium should be substantially less than the optical path length through the medium. A sampling time of about 1 picosec may be achieved, although the response of the cell 17 may be relatively slow. The output of cell 17 may be fed to the holding circuit 19 of a sampling oscilloscope to build up a complete representation of a recurrent electrical signal by suitable timing of the light pulses, and there is also mention of the application of sampling processes to time division multiplex communication. The element 5 may be crystalline, e.g. KDP, or its deuterium analogue, ADP, LiNbO 3 , Ba 2 NaNb 5 O 15 , GaAs, or a liquid with a large Kerr effect, e.g. nitrobenzene. The velocities of the light pulses and electrical signals are matched by choosing a material 5 of suitable refractive index and dielectric constant, inclining the paths of the light and electrical signals, varying the spacing between the crystal and conductors 7, or by filling the space between the conductors 7 and crystal 5 with a material of different dielectric constant.

Abstract: 992,121. Chucks. BUCHUNGSMASCHINENWERK KARL-MARX-STADT VEB. Nov. 1, 1961, No. 39114/61. Heading B3B. In a hollow-spindle auto-lathe, the collet 6 is mounted within eccentric sleeves 7, 8, and means is provided for turning the sleeve 7 relatively to the sleeve 8 to effect adjustment of the collet laterally of the spindle 1 while the spindle rotates. The collet is closed on the bar-stock (not shown) by endwise movement of a push-tube 24 engaging the end of the sleeve 8 and operated, against the pressure of a spring 12, by levers 25. These, in slots 26 in the spindle and pivoting about their ends 27 in the groove 28 of a ring 29, engage the end of the tube 24. A collar 30 surrounding the levers is moved to operate them by a lever, Fig. 3 (not shown), engaging a groove in the collar. The sleeve 8 is keyed at 9 to the spindle, and the sleeve 7 engages screw-threads on a tube 11 formed at its other end with teeth 42, 44 engaging teeth 41, 43 on a ring 13, which has projections 16 engaging slots 17 in the end 18 of a feed-tube 19. A guide-tube 15 for the ring 13 is carried by the tube 11 and supports a spring 14 for pressing together teeth 41-44. A roll 38 is mounted on the feed-tube 19 and engages a spiral cam slot, Fig. 5 (not shown), in a sleeve 35 secured to the end of the spindle 1 so that endwise movement of the feed-tube by means of a slide 23 also effects its rotation. Operation.-The collet is adjusted laterally during operation of the push-tube 24 for releasing the collet for a feed step of the bar stock. With the collet released, the feed-tube is advanced by the slide and rotated by cooperation with the cam-slot. The slots 17 in the advancing end 18 of the feed-tube rotate the ring 13 relatively to the tube 11 until the sloping surfaces 41 pass over the adjacent tooth edge 44, when the slide is returned, rotating the feed-tube in the opposite direction. Due to the tooth-edges 43, 44, the ring 13 and tube 11 rotate together in the opposite direction, effecting rotation of the eccentric sleeve 7 and thus lateral movement of the collet.

Abstract: 957,856. Centrifugal pumps. P. D. JENSEN. Oct. 16, 1962 [Jan. 5, 1962], No. 39165/62. Heading F1C. A liquid circulating pump, preferably for central heating installations, in which the pump impeller and the electric driving motor are enclosed in a casing, the motor rotor being located in a chamber which is surrounded by a tubular member and contains lubricating and cooling liquid, while the impeller is located in a pressure chamber isolated from the suction chamber of the pump by means of a partition which encloses the central feed opening to the impeller, is characterized in that in the partition there is provided a device which is adjustable from the outer side of the casing and is adapted to provide a liquid flow passage with variable area from the pressure chamber to the suction chamber. The impeller 3 is housed in a pressure chamber 5, which is separated from the suction chamber 7 by a partition 6. The lower end of the pump shaft 2 is supported by a conical bearing 4 carried by a sleeve 16 which is rotatably supported by a boss 17. When the sleeve 16 is turned by means of a square or hexagonal portion 21 of a plate 19, members 14 having a screw-threaded engagement 15 with the sleeve are raised, whereby a disc 8 connected to the members 14 by means of a perforated cylinder 12 is raised into the dotted position to afford an annular by-pass passage around the impeller eye for the return of liquid from the pressure chamber 5 to the suction chamber 7. A guide pin 101 prevents rotation of the disc 8. The adjustment of the position of the disc 8 is made after installation of the pump in a central heating plant whereby a sufficient proportion of the pump output is returned to the suction chamber 7 to reduce the net capacity of the pump to the required value.
