Title: Method of manufacturing neutral colloidal calcium carbonate
IPC: C01F11/18
Filed: 1937-07-27
Abstract: A colloidal suspension of neutral calcium carbonate is obtained by kneading calcium oxide with water while keeping the temperature below 50 DEG  C. to prepare a milky solution containing 10-30 per cent of calcium hydroxide, which is then diluted to a density of 30 DEG B<\>ae.  It is then converted into basic carbonate by passing in a gas containing 15-50 per cent of carbon dioxide at a temperature below 35 DEG  C. and continuing the action of the carbon dioxide until the basic carbonate is converted into neutral carbonate.  Small quantities of acids, alkalis, water - soluble salts or polyhydric alcohols may be added during the slaking of the calcium oxide. Protective colloids, e.g. 1-20 per cent by weight of lecithin, castor oil soap, sulphonated castor oil soap, sulphonated oils, casein or an emulsion of rosin or synthetic resin may be added to the final dispersion, which may be dried. The product may be used to reinforce rubber, as a coating or filling material for paper, in sizes or as a toilet powder.

Title: Improvements relating to the separation of fibers from bast-fiber stalks
IPC: D01B1/10
Filed: 1953-07-28
Abstract: 733,838. Decorticating apparatus. BOBKOWICZ, E. July 28, 1953, No. 20937/53. Class 120(1). Fibre is separated from bast stalks by splitting the stalks longitudinally, laying the split portions side by side with the bark all facing in one direction, flexing the split portions and, while flexed, cutting the wood core transversely at intervals without cutting the bark, and subsequently picking the wood pieces from the bark. As shown, a vibrator unit B pushes stalks into compartments of a divider unit C, each compartment forming a narrowing chute which delivers one stalk at a time onto a conveyor belt 34 whence the stalks are fed side-byside to a cutting unit D. In unit D, driven rollers 45, 46 feed each stalk between channels in the surfaces of co-operating rollers 60, 65, a knife 61 mounted in the middle of the channel of roller 60 splitting the stalk longitudinally. The stalk then passes between further mating rollers 70, 75, 70a, 75a and 70b, 75b of a flattening unit E ; rollers 70, 70a, 70b have wedge surfaces of increasing bluntness which turn the halves of the split stalk until they are disposed with the bark downwards and wood upwards. In this condition the stalks are flexed around a drum 90 of a cutting and stripping unit F where the wood core is cut at intervals by the chisel edges 92 of a rotary cutter 91, the edges of the blades being spaced from the drum surface so as not to cut the bark. The cut wood is picked off by plates 101 on a rotary cylinder 105 and by a chisel-edged roller 109a, and is removed by a screw conveyer 107. The bark then passes around a knurled drum 411 of a scrubbing unit H where spiked or scraper-edge rollers 419, 423, 427 and 431 scrape the gummy material from the bark and liberate the fibres which are then scrubbed by brushing rollers 445, 449, 453, 457 and 461. Each scraping or brushing roller comprises scraping or brushing elements running axially of the roller, and, located between such elements, axial perforated pipes through which water is projected onto the bark. The solids detached by the scraping rollers are removed by a screw conveyer 500. The scrubbed fibre is discharged in web form between belts 475, 477.

Title: Improved sprayable cement mortar
IPC: B28C5/00
Filed: 1937-07-29
Abstract: A sprayable cement mortar is prepared by passing a mixture of Portland cement, powdered or granular aggregate and water through a plate mill, until a jelly-like paste is obtained.  The preferred mill has cast-iron plates, and with an outside diameter of 8 in. runs at an optimum speed of 2,000 revs. per min.  The time of milling is 2-3 min., the gel formation is expedited by raising the temperature by friction in the mill, or by using warm water or aggregate, to 70-150 DEG  F.  Rapidity of hardening may be increased by the addition of 1/2 -2 per cent of hydrochloric acid. Adhesion to smooth surfaces is increased by the addition of up to 5 per cent of the cement of boiled linseed oil.  Specifications 19813/92, [Class 22], and 412,556 are referred to.

Title: External powder feed hand-scarfing process and apparatus
IPC: B23K7/08
Filed: 1951-09-10
Abstract: 687,465. Dividing by fusion. UNION CARBIDE & CARBON CORPORATION. Sept. 10, 1951 [Sept. 29, 1950], No. 21326/51. Class 83 (iv). A method of scarfing an oxidation-resistant metal body by directing at an acute angle against a surface of said body a thin, flat stream of oxygen and a number of preheating flames adjacent said stream, and discharging a gas laden with a combustible metal powder at an acute angle through said preheating flames into said oxygen stream, is characterised in that the powder-laden gas is discharged through a passage terminating in an oblong orifice so as to form a thin flat stream equal in width to said oxygen stream, said powder-laden gas prior to its discharge from said orifice being directed against an inclined wall of said passage extending toward a long side of said orifice. A hand scarfing blow-pipe 10 comprises an oxyfuel gas nozzle 12 and a powder nozzle 14 held together by a bracket 16 which includes a skid 18. The nozzle 12 has a slotted orifice 44 for discharging a flat stream of oxygen 45 towards the work W at an angle of between 30 degrees and 50 degrees, and also rows of gas ports 46 for preheating jets 47. The powder nozzle 14 is a stainless steel tube having a flat exit portion 50 which merges with a flared inlet portion 52 by way of a crimped section 40 which causes the powder stream to impinge on the inclined lower wall of the tube and to flatten out so as to obtain good powder distribution in the stream as it leaves the outwardly flared exit orifice. The powder nozzle 14 is preferably disposed at an angle of about 35 degrees to the scarfing nozzle 12. The powder nozzle may be provided with double crimps at 54 and 55 (Fig. 6) to ensure more uniform distribution. The width of the streams of powder and scarfing oxygen are less than three inches.

Title: Improvements in and relating to relays
IPC: H02H7/30
Filed: 1931-07-27
Abstract: 391,748. Protective cut-out arrangements. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. July 27, 1931, No. 21370. Convention date, July 26, 1930. Void [Published under Sect. 91 of the Acts]. [Class 38 (v).] Impedance relays, the time of operation of which depends on the impedance from the relay to the fault, are arranged so that their sensitiveriess is changed step by step after operation has been initiated, and the pointer deflects in a negative sense for impedances below a given value and in a positive sense for impedances above that value. Thus, assuming that the relay in I is set at 4 ohms for the first step and 9 ohms for the second step, and that a fault occurs at a, the relay will deflect in a negative sense and tripping of the breaker will occur. For the same impedance figures, however, with a fault at b the relay will deflect in the positive sense and not close its contacts. The timing mechanism of the relay is arranged to return to its initial position, whereupon a second operation takes place if the fault still exists. This time, with the setting at 9 ohms, it will be seen the instrument will deflect negatively and close its contacts, always supposing that the relay in II has failed to operate. Preferably the setting is changed by the timing mechanism, and the relay definitely closes its contacts independently of the impedance after a given number of operations. The Specification refers also to energy direction, to indicating devices, and to a motor or clockwork for driving the timing mechanism.
