Patent ZA-914806-B (ZA)
Title: Process for the preparation of ethylene/vinyl ester copolymers
Inventor: HOBES JOHN
IPC: C08F2/00
Filed: 1991-06-21
Abstract: Copolymers of ethylene are prepared by polymerising ethylene with estes of vinyl alcohol in the presence of free-radical scavengers and in the absence of solvents and emulsifiers. The addition of free- radical scavengers allows the polymerisation temperature to be increased compared with a procedure in which no free-radical scavengers are used.

Title: C8 aromatics isomerization using catalyst containing modified silicoaluminophosphate molecular sieve
Inventor: HAMMERMAN JOHN I
IPC: B01J29/85
Filed: 1996-04-16
Abstract: A non-equilibrium C8 aromatic-feed mixture is selectively isomerized to obtain an isomerized product enriched in para-xylene by contacting the feed in the presence of hydrogen with a catalyst containing a combination of a platinum group component with an SM-3 acidic crystalline silicaaluminophosphate molecular sieve at C8 aromatic isomerization conditions.

Title: A method for the extraction of oil by mircoemulsification
Inventor: OLDFIELD CHRISTOPHER
IPC: C09K23/00
Filed: 2000-03-13
Granted: 2003-08-20
Abstract: The invention provides a method for the removal of oil from oil-contaminated solid wastes such as drilling mud waste, sand, soils, metal fabrication swarf, newly manufactured, printed circuit boards and fractions thereof, by mixing the preparation such as an alkyl sulphonate such that the oil is extracted as an oil-in-water (O/W) microemulsion. The microemulsion and solids phases can be separated by a suitable technique such as centrifugation; residual O/W microemulsion can be removed from the solids by an aqueous rinse. The oil can be recovered from the O/W microemulsion by suitable techniques including, but not limited to, temperature-induced phase-separation.
Patent GB-2379147-B (GB)
Title: Sound processing
Inventor: MALHAM DAVID GEORGE
IPC: H04S1/00
Filed: 2001-04-18
Granted: 2003-10-22
Abstract: The spatial radiation characteristics of a sounding object are encoded by spherical harmonics. The shape is decomposed (105) into a weighted sum of spherical harmonics, comprising at least the order 0 components and such higher orders as are deemed necessary. The weights are stored individually. Each shape as defined by the individual spherical harmonics is also used to calculate an impulse response for that spherical harmonic (106). These impulse responses are of a modified form where the impulse consists of sums of equally weighted components, so each time point can only take integer values for the size of the impulse at that point. The modified impulse responses are transformed into spherical harmonic form (107), after which the apparent orientation and distance of the sounding object may be varied. Any sound may be processed by using the impulse response so generated (111).

Title: Alkali earth aluminate-silicate photoluminescent pigment which is activated by rare-earth elements
Inventor: SUN ZHAO
IPC: C09K11/77
Filed: 2001-04-18
Granted: 2003-04-23
Abstract: An alkali earth aluminate-silicate photoluminescent pigment which is activated by rare-earth elements according to the invention has excellent luminescent properties such as high initial intensity and long afterglow time. The pigment may readily be used in the manufacture of luminescent plastics; rubbers, coatings and ceramic glazes because it appears neutral in aqueous medium and the sinters are easily crushed into powder. The pigment has the composition formula of MO.aAl2O3bSiO2cL:fX, in which MO is represented by at least one oxide selected from alkali earth metals such as SrO, CaO and MgO; L is a mineraliser selected from minerals, X is an activator selected from rare-earth elements; and a, b, c and f are variable factors having values in mole. The pigment is produced by firing selected ingredient materials in a controlled environment of a reducing atmosphere, filled with selected gases or elements, at a temperature of 1200-1450° C. for 2-4 hours to produce a sinter; and the sinter is finally produced into photoluminescent pigments.

Title: Method of forming a welded joint between polyolefinic members
Inventor: STAFFORD TREVOR GEORGE
IPC: B29C65/00
Filed: 1991-04-24
Granted: 1995-02-08
Abstract: A polyethylene pipe 10 is joined by a welded joint to a cross-linked polyethylene coupler 14 which has been expanded to make the coupler heat recoverable. Radiant energy (eg light in the visible spectrum or infra-red light) illuminates the outer surface of the coupler 14 supplied by an array of 150W reflector lamps 20. The coupler 14 shrinks and is forced into engagement with the pipe 10 and the pipe 12 to join the pipes. A fusion welded joint is formed between the coupler 14 and each pipe 10, 12. In an alternative a pipe is drawn down and inserted in an aperture through the wall of another pipe. A lamp is inserted in the drawn down pipe and the radiant energy causes the pipe to expand into engagement with the edge of the aperture and to be joined to it by a welded joint. <IMAGE>

Date Jan. 9, 1997A piston mechanism with a flow passage through the piston includes a cylinder which has a closable cylinder passage at one extremity thereof; a piston, axially movable in the cylinder, which has a closable piston flow passage and has in its outer circumference a groove in which a piston ring is situated for sealing between the piston and the cylinder; and a movement mechanism to axially move the piston in the cylinder. The movement mechanism includes a crank shaft which is mounted in a crank chamber and a piston rod which, on the one hand, is hingedly connected to the piston by a first bearing and, on the other hand, is hingedly connected to the crank shaft by a second bearing. The piston ring is mounted with a certain axial clearance in the groove. The piston flow passage extends over the groove and the piston ring forms a valve for closing and opening the piston passage. The piston passage opens into a back side of the piston and thus medium that flows through the piston passage also flows over the first bearing by which the piston rod is connected to the piston.
