Title: Improvements in vacuum-tight sleeve-insulators for leading electrodes through the walls of metal vessels
IPC: B23K26/70
Filed: 1923-11-01
Abstract: 206,510. Akt.-Ges, Brown, Boveri, et Cie. Nov. 3, 1922, [Convention date]. Joint-making packing. - In a vacuum-tight sleeve insulator for leading electrodes through the walls of metallic vessels, the joints are made with packing proper h, for example asbestos, lead wool or lead cord, combined with a liquid seal f consisting of a viscous substance having a low vapour pressure, for example picene or oil varnish, poured upon the packing. The sealing- liquid is of such a nature that it cannot exude through the pores or interstices of the packing to. reach the actual joint at ordinary working temperatures. Underneath each packing place a gutter m which can be removed for emptying is provided to catch any leakage of the sealing- liquid.

Abstract: Vitamin B12 is obtained by culturing a Vitamin B12 producing strain of micro-organism in a cobalt containing nutrient deficient in cyanide ions, extracting the LLD active components from the medium, treating the extract with a particulate cation exchanger, whereby the LLD active components are adsorbed on the exchanger, eluting said components from the exchanger, and treating the eluate simultaneously with a source of cyanide ions and light to convert the LLD active components to Vitamin B12.  The preferred micro-organism is Propionibacterium freudenreichii but Streptomyces griseus, S. aureofaciens, S. albidoflavus, S.antibioticus, S. colombienses, S. fradiae, S. roseochromogenus, and S. olivaceus; Aerobacter aerogenes; Ashbya gossypii; and Mycobacterium phlei, M. smegmatis and M. tuberculosis may also be used.  Assimilable cobalt may be provided by cobalt chloride or nitrate or as cobalt containing yeast or in a naturally occurring source such as beet molasses. In a preferred embodiment an organic medium is fermented for 4 days with P. freudenreichii and then the LLD active components released by heating to 82 DEG  C. and then the liquid concentrated in vacuo. The concentrate is acidified, absorbed on "Amberlite" (Registered Trade Mark) IRC-50 resin and then eluted after treatment with sodium carbonate.  The eluate is adjusted to pH 7, cyanide added and the whole subjected to the illumination of an incandescent lamp for 8 hours.  The Vitamin B12 is recovered by extraction with phenol - benzene.

Abstract: 1,074,254. Fastener-driving tools. V. D. ROOSA. July 8, 1964 [Aug. 2, 1963], No. 28149/64. Heading B4C. A fluid-pressure actuated fastener driving tool comprises a driving piston 16 having surfaces 17, 18 adapted to be connected to the pressure source under the control of an actuating valve 44 and a control valve 32 operatively connected together. The actuating valve 44 is slidable in a bore 14 in the cylinder head and is formed with a recess 46 communicating with a chamber 31 via a port (56, Fig. 3) and with atmosphere via a passage 45 and port 54. The control valve 32 is normally urged into contact with the top edge of the cylinder by a spring (41) and fluid-pressure, such as compressed air, fed from a reservoir 28 via chamber 31, port (56) and recess 46. In operation, upon depressing a trigger (61, Fig. 1) the valve 44 is moved to a position in which communication between the port 56 and the recess is cut off, the air in the recess being exhausted via the passage 45 and port 54 after a ball 47 has been unseated by means of a stem 42. Air pressure in the chamber 31 then lifts the control valve 32 so that air enters the cylinder to drive the piston on its working stroke. Upon release of the trigger the valve 44 returns so as to exhaust the air above the piston and thereby allow the latter to be returned by air fed below the head portion of the piston.

Patent GB-364110-A (GB)
Title: Improvements in the manufacture and production of high quality lubricating oils
Filed: 1930-09-22
Abstract: Improved lubricating oils are obtained by enriching in hydrogen lubricating oils of low viscosity which may contain paraffin waxes, cracking the enriched oils, and condensing the cracked products by means of condensing and/or polymerizing agents such as chlorides of aluminium, zinc, iron, boron and phosphorus, activated aluminium sodium, zinc dust, &c.  The oils are enriched with hydrogen by treatment with hydrogen at temperatures about 390-430 DEG  C., preferably in presence of catalysts of the sixth group. Alternatively the oils may be separated into fractions rich and poor in hydrogen by differentiating solvents, e.g sulphur dioxide, phenol, aniline, &c., and the fraction poor in hydrogen then hydrogenated. The cracking stage is carried out at about 400-600 DEG  C., preferably in the presence of catalysts, and may be effected in several stages.  The condensation reaction is carried out at about 150 DEG  C., preferably in presence of substances of large surface area, e.g. Florida earth, bleaching earth, active silica, &c. Mineral oils cracking and destructive hydrogenation products may be added.  Crude paraffin wax containing liquid constituents is treated with phenol at 80-90 DEG  C. and the products not soluble in the phenol are distilled under vacuum.  The distillate is cracked several times at 490-520 DEG  C., the constituents boiling below 300 DEG  C. formed in each stage being removed and collected.  These constituents are then polymerized in presence of aluminium chloride at 30-100 DEG C.  The liquid polymerization products after removal of sludge are distilled and after removal of lighter constituents a lubricating oil is obtained having a viscosity of 2,4 DEG  Engler at 99 DEG  C. Specifications 141,753 and 299,086, [both in Class 91, Oils &c.], are referred to.

An Archimedean screw pump for raising slurry or sludge comprises a steel screw 2 operating within a cylindrical casing 1 of steel or plastics material. An outlet pipe 7 extending above the casing 1 has a quick-release coupling 10 for a spill-spout 9. The casing 1 and a power take-off gear-box D are mounted on a supporting frame 11 which may be provided with wheels for transporting the pump. The lower end of the casing 1 is cut away to provide a sharpened arcuate edge 3 which co-operates with the screw 2 to cut any solid matter drawn into the casing. The edge 3 also acts as a stone deflector. Alternatively, the lower end of the casing may be cut away on a diameter to leave a trough-shaped part, and the adjacent part of the screw 2 may be notched. The gear-box D, which can be connected to the power take-off shaft 19 of a farm tractor, drives the screw 2 directly or through a belt and pulleys 5, 6 or a sprocket chain or gearing. An electric or hydraulic driving motor may be used. As shown at 12, the frame 11 can be fixed to the surround of a slurry pit 20. Alternatively it can be carried at B by the power lift linkage of a tractor. Instead of being connected to the top link of the linkage, the frame 11 may be connected at C by a chain or cord to a fixed point A on the tractor, point C being higher than point A; when the linkage is lifted hydraulically from B to B<SP>1</SP>, point C describes an arc about point A and causes the frame to tilt as it is lifted, so that the pump assumes an inclined position above ground level for transport purposes. In a modification, Fig. 2 (not shown), a blockage can be cleared by applying a box spanner (17) to a square or other shaped end of the drive spindle (4) to turn the screw (2) backwards. The screw (2) can then be detached from the drive spindle and withdrawn for cleaning. If the pump is driven by an electric motor, the motor control gear may include a cut-out device for dealing with blockages. The cut-out device includes a push button linked to a reversing switch to provide a reversal for clearing the blockage and lasting for 1/10 second before cut-out occurs.
