Patent ZA-827632-B (ZA)
Title: Electric traction current-collector
Inventor: FERGUSON IAN CAMPBELL
IPC: B60L5/20
Filed: 1982-10-19
Abstract: An electric traction current-collector, such as is described in United Kingdom Patent Specification No. 1 374 972, has a carbon current-collector block (1) housing a rupturable tubular container (7) for air under pressure applied through a pneumatic control system for a pantograph or other carrier so that loss of air pressure due to rupture of the container causes the current-collector block to be retracted. The container (7) is so thin that, if it is not completely housed and supported, it bursts under the applied air pressure and consequently any defect in the carbon block which spoils complete support of the container causes retraction of the current-collector.

Title: Process for continuous production of beverages
Inventor: DUMONT YVES
IPC: C12H1/02
Filed: 1983-03-16
Abstract: This invention relates to a process for the clarification of juices and other similar beverages such as wine, beer, cider, etc. . . . which comprises a flotation stage. All known clarification processes used in the commercial production of beverages are discontinuous in that they rely on a sedimentation stage and/or require the use of expensive centrifugal equipment which require regular cleaning and maintenance. The use of the invention allows the commercial clarification of beverages without the necessity of going through a sedimentation stage or the use of centrifugal equipment. The process comprises three essential stages, i.e.: the formation of a flotable floc in the untreated beverage, the continuous introduction of the coagulated beverage in a flotation vessel, the flotation of the floc by microbubbles formed in the beverage and the continuous removal of the clarified beverage.

Title: Agglomeration
Inventor: BUHLER MARCEL
IPC: A23P1/02
Filed: 1986-10-01
Abstract: Apparatus particularly for agglomerating particles of different products. A rotatable drum, which has a wall which defines a cylinder and a cylinder void, is mounted on a frame in a horizontal or inclined position. The apparatus includes provision for rotating the cylinder in one direction thereby defining ascending and descending halves of the cylinder. A first part of the cylinder receives particles of a product and has means, such as projecting elements, to rotate the particles for forming a vortex of particles about an axis within the ascending half of the cylinder void such that the axis of the vortex is displaced from and substantially parallel to a central longitudinal axis of the cylinder. The apparatus also includes provision for introducing a product into a second part of the cylinder in the ascending half of the cylinder void, the second part being displaced from the first end of the cylinder and abutting the first part of the cylinder, for distributing secondary product into the vortex of particles within a zone about which the vortex rotates. A spraying device is positioned in the second part of the cylinder void in the descending half of the cylinder for spraying an agglomerating agent onto the particles of the vortex from outside of the vortex.

Title: Cbn/cbn composite masses and their preparation
Inventor: CORRIGAN FRANCIS RAYMOND
IPC: C04B35/583
Filed: 1991-12-05
Abstract: In the case of a mouthpiece (1) for moulding a ceramic mass (T) fed to it, which mouthpiece can be fitted to a diehead (7) of an extruder, to regulate the flow rate of the ceramic mass (T) in the area of the mouthpiece (1) use is made of adjusting elements (11) which are arranged, preferably all around, displaceably in parallel with the longitudinal axis (A) of the mouthpiece (1) in the frame (2) of the latter on one or more of the side walls (3, 4) bounding the mouthpiece opening (10) and can be introduced into the diehead (7). By this design it is possible to make the flow rate of the ceramic mass (T) more uniform in the area of the mouthpiece (1), so that unequal compressions of the clay strand, which can result in stress cracks during drying and/or firing of a moulding separated from the said strand, can be reliably avoided. In addition, the regulating of the flow rate can be performed without the mouthpiece (1) having to be removed from the diehead (7) for this purpose. Rather, the adjusting elements (11) can be actuated from outside during operation without any problems. <IMAGE>

Filed: 1992-04-21
Abstract: A method and apparatus provide for the production of low kappa number (e.g. below 20) kraft paper pulp, and a low viscosity black liquor which is easily transported to a recovery or disposal stage. Comminuted cellulosic fibrous material is steamed (at 11), passed to a treatment vessel (13, 113, 213), and then introduced into the top of a continuous digester (24, 124, 224). Black liquor is withdrawn from the digester (at 32, 132, 232) and heated (in 35, 135, 235) about 20-40 degrees C above cooking temperature (e. g. to about 170 degrees C), and then introduced into contact with the material in the treatment vessel. After the material is treated with the black liquor, it is withdrawn from the treatment vessel (at 17, 117, 217), and passed to the recovery or disposal stage. White liquor may be introduced into the treatment vessel (at 18, 118, 218) after black liquor withdrawal, after passing in heat exchange relationship (119, 219) with liquid recirculated from an impregnation vessel to a high pressure feeder (21, 121, 221). Alkali may be added to the black liquor withdrawn from the digester (at 34), prior to heating, and after heating it may be passed to a reaction vessel (36, 136, 236). <IMAGE>

Title: Aqueous liquid detergent compositions containing deflocculating polymers
Inventor: THOMAS REPINEC STEPHEN JR
IPC: C11D3/37
Filed: 1995-06-22
Abstract: The present invention provides for concentrated, structured liquid detergent compositions in the form of lamellar surfactant droplets dispersed in an aqueous electrolytic continuous phase comprising a mixture of:     a) from about 10 to about 45% by weight of a surfactant;   b) at least one detergent builder; c) from about 0.01 to about 5% by weight of a deflocculating polymer composition having a weight average molecular weight in the range of from about 1500 to about 50,000 and containing polymer chains of the structure P-SR, wherein P represents a polymer chain segment of a hydrophilic polymer and SR represents a mercapto end-cap group, R being an organic hydrophobic radical containing from about 4 to 28 carbon atoms; and   d) water.   The presence of the deflocculating polymer in the composition both stabilizes the detergent composition and retards the propensity of the lamellar droplets dispersed in the aqueous phase to flocculate, particularly where the droplets occupy a higher volume ratio as the result of high concentrations of surfactant present in the detergent.   The invention also provides both phosphate built and non-phosphate built detergent compositions having a viscosity in the range of from about 500 to 20,000 cps, more preferably from about 2,000 to 10,000 cps, having improved flowability and stability.

Granted: 1993-06-30
Abstract: A nut fastener device for a blind hole anchor has the nut 14 made frusto-conical with the smallest diameter knurled at 30 and with the largest diameter provided with relieved and back tapered flanks 20. The nut is made integral with a sleeve 10 having flange 12 and a further knurled zone 32, and a sheer zone 16 between the sleeve and nut. During the installation the nut is pulled into the sleeve to expand the sleeve and deform it to the cross sectional shape of the nut so as to provide an angular fix. The sleeve is effectively fixed to the sheet material by the flange on the one side and the deformation of the sleeve on the other side of the sheet. The knurled bands which become axially aligned increase the angular hold of the device in the sheet and of the nut in the sleeve. <IMAGE>
