Title: Improved method of and machine for stenciling granular inlaying composition in the manufacture of linoleum and other sheet materials
IPC: D06N7/00
Filed: 1933-06-06
Abstract: 418,156. Stencilling-machines. ARMSTRONG CORK CO., Lancaster, Pennsylvania, U.S.A.-(Assignees of Berger, J. L. ; 1059, Locust Street, Columbia, Pennsylvania, U.S.A.) June 6, 1933, No. 16246. Convention date, June 14, 1932. [Class 140.] In stencilling granular inlaying composition, for example in the manufacture of moulded inlaid linoleum, the composition is fed to the openings of the stencil and an inclined blade or brush is moved across the openings to compress the composition therein. The composition is fed from a hopper 19, Fig. 1, wherein it is uniformly distributed by a screw conveyer to a measuring device comprising a plurality of vanes 15, Fig. 3, rotating within a shell 17 having intake and discharge openings 18, 181. The measuring device is rotated by star wheels 20 operated by spaced lugs 21 on an endless chain 10. The composition is spread by metal or rubber scraper blades 28 attached to buckets 2<a>-2<i> which are moved across a stencil 5 by the chain 10. Successive blades are arranged at decreasing angles with respect to the stencil, so that the composition is ultimately compacted in the stencil openings. The buckets 2<a>-2<@i> serve to convey excess composition away from the stencil and discharge it into a metal guard 30 or direct into the hopper 19 by means of a hinged bottom which is unlatched by contacting with a slide-block 52. Preferably, the bucket 2<@i> is provided with a scraper blade to prevent any composition travelling down a guard 51 into the stencil openings when the mechanism is stationary. An additional guard 55 is provided above the stencil and is cleaned by a brush 56 which is held out of operative position when travelling over the stencil. The machine is provided with automatic starting and stopping switches 60, 61 in series, which are respectively operated by the raising and lowering of the stencil plate 5 and the passage of a bucket past an operating arm 63.

Title: Improvements in or relating to the purification of sewage or waste liquors
IPC: C02F3/12
Filed: 1936-06-11
Abstract: Putrefiable matters are separated from domestic sewage and industrial waste waters by means of asbestos fibres which are kept uniformly suspended in the liquid by means of air or other gas containing or liberating oxygen.  The gas may be introduced in a fine state of subdivision.  The fibres may constitute a floating filter from which the purified liquid overflows.  Coarse matter may be separated from the liquid by means of a preliminary filter or settling chamber.  Any asbestos fibre carried away by the purified liquid may be collected by means of a peat filter.  It is stated that bacterial growth is promoted by the aeration in the floating filter and when the filter is being charged with clean asbestos, some of the material previously used may be retained to aid the growth.

Title: Improvements relating to alternating current electrical distribution systems
IPC: H02H3/40
Filed: 1926-07-01
Abstract: 254,732. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Goldsborough, S. L.). July 2, 1925, [Convention date]. Cut-out arrangements.-In high voltage alternating current distribution systems having an earthed neutral and unearthed sub-station stepdown transformers, selective protection is obtained by means of the impedance relay described in Specification 216,531, and in order to dispense with the expensive high voltage potential transformers which should feed the relay, the relatively low voltage on the secondary side of the substation transformers is made use of, with a corrective voltage and phase adjustment necessitated by the shift in the unstable neutral of the unearthed transformers. As shown in the Figure, the line A, B, C with an earthed neutral is supplied by the generator 1 and supplies stepdown substation transformers 4. The protective relays 6, one for each phase are energized at 7 by current transformers and have restraining windings 11, for the contact-member 9, energized from the secondary of a potential transformer 16 across the secondary of the step-down transformer. This energization is in each case corrected by the inclusion in the circuit of the voltages across an adjustable resistance 23 and an adjustable resistance 24 these being connected oppositely across two similar secondaries 25 of a subsidiary transformer the primary 26 being connected across that phase of the potential transformer which does not contain the line protected by the relay in question. In this way the voltage winding of the relay associated with any one phase conductor is energized by a voltage derived from that conductor added vectorially to a voltage derived from the other phase conductors modified in phase and magnitude so that the resultant voltage applied to the winding is proportional to that in the phase conductor. A modified arrangement employing reactance transformers is described in respect of star-delta-connected substation transformers.

Title: Improvements in or relating to streptomycin salts and processes for their preparation
IPC: C07H15/238
Filed: 1956-05-30
Abstract: The invention relates to pantothenic acid salts of strepromycilidene isonicotinyl hydrazone of general formula: <FORM:0795757/IV (b)/1> in which n is 1, 2, 3 or 4; or mixtures thereof.  The salts are non-toxic tuberculostatics which have enhanced lipoid-solubility properties.  They are produced by reacting an inorganic salt of streptomycilidene isonicotinyl hydrazone with a water-soluble salt of pantothenic acid in an aqueous medium.  Alternatively, the components of the hydrazone may be reacted with the pantothenic acid salt.  The alkali metal and alkaline earth metal salts of pantothenic acid may be used.  Inorganic salts formed in the reaction are precipitated by the addition of an alkanol such as methanol, removed and the pantothenate of the invention precipitated by the addition of acetone or ether to the clarified reaction liquid.  In examples, streptomycilidene isonicotinic acid hydrazone sulphate are reacted with calcium pantothenate and the calcium sulphate produced removed by the addition of (a) methanol or (b) barium hydroxide. Specifications 724,863 and 771,338 are referred to.
