Title: Yeast hybrid vectors
Inventor: KINGSMAN ALAN JOHN
IPC: C12N1/16
Filed: 1984-09-19
Abstract: A yeast vector including either or both of the REP1 and/or REP2 gene(s) derived from the yeast 2 mu  plasmid, located relative to a control sequence capable of directing expression of either or both of the REP1 and/or REP2 gene(s) in which the control sequence includes a promoter which operates substantially independently of vector copy number in a host organism transformed with the vector. The control sequence includes a controllable promoter such as the yeast PGK promoter which allows for copy number control of expression vectors cotransformed with the yeast vector. The yeast vector, which may be integrated into the yeast chromosomal genome, is used in a process for producing a polypeptide in which the production of polypetide is maintained at a low level until a predetermined culture cell density is achieved at which point the expression vector copy number and/or the expression level are caused to increase by altering the culture conditions.

Patent GB-2166876-A (GB)
Title: Method for nondestructive testing of coating adhesion
Inventor: IVIE RANDELL G
IPC: G01N19/04
Filed: 1985-11-07
Abstract: A method for applying a consistently perpendicular minimum tension force to a dolly 16 for testing to see if the adhesive bond strength between a coating 12 and a substrate 14 meets a minimum specification for such bond involves using a tester having a ram 34 passing through an axially centered opening 18 in the dolly 16 which is bonded at 25 to the coating 12. Piston and cylinder means 30,32 are associated with the ram 34 and the dolly 16 so that pressure within the piston chamber forces the ram 34 against the coating 12 and thereby causes the development of a tension force on the dolly 16 which is perpendicular to the coating 12. The pressure is increased only to a point where the tension force is equal to the minimum specification for a good bond between the coating and substrate. If the coating has not separated from the substrate, the bond therebetween meets the specification and the testing apparatus is removed by causing the bonding means 25 attaching the dolly 16 to the coating 12 to fail e.g. by heat, a solvent, or by impact. <IMAGE>

Title: High-speed grinding method for producing a thread-cutting tool eg a thread tap
Inventor: JUNKER ERWIN
IPC: B24B3/18
Filed: 1985-12-02
Abstract: A high-speed grinding process, whereby the thread-grinding process and the chamfer-grinding process may be effected by two co-axial grinding wheels I, II in one clamping procedure and in directly successive operating steps. In such a case, to produce the eccentric relief of the chamfer in the same workpiece mounting, the grinding wheel II effects a radial feed B movement relative to the rotating workpiece 2, whereby the grinding wheel effects the radial feed movement at intervals according to the number of grooves in the rotating workpiece and is then moved into its initial position and the workpiece stops and is subsequently rotated further about its longitudinal axis over a distance which corresponds to one groove width. The grinding wheel II is then moved again with rotation of the workpiece 2 over such a distance until the next land is ground, and the sequence is repeated for each land in dependence upon the number of grooves in the workpiece until such time as the eccentric relief is produced around the entire workpiece. <IMAGE>

Title: Clay/soda ash fabric softening particulate agglomerate, proc esses for manufacture and use thereof, and detergent compositions containing it
Inventor: RAMACHANDRAN PALLASSANA N
IPC: C11D3/60
Filed: 1988-10-21
Abstract: Agglomerated particles of finely divided fabric softening bentonite and sodium sulfate particles have been found to possess improved fabric softening properties, compared to agglomerated bentonite, especially when employed in the hand washing of laundry which is subsequently line dried. Such agglomerates are also of excellent particle strength and are readily dispersible in water. The described product may be made by agglomerating finely divided bentonite and sodium sulfate powders with the aid of excess moisture, after which the agglomerated particles resulting are dried and those of desired size, preferably in the No's. 30 to 100 sieve size range (U.S.), are obtained. The fabric softening agglomerate made may be mixed with spray dried synthetic organic anionic detergent composition beads of about the same or lower bulk density, preferably in the 0.3 to 0.5 g./cc. range, with about 5 to 30% of the agglomerate particles being present, to make a non-segregating fabric softening particulate detergent composition of improved softening properties. Detergency, soil anti-redeposition properties, bead physical characteristics and processing are improved by the presence in the detergent composition of a minor proportion of a water soluble copolymer of maleic and acrylic acids which, unlike other polymers which can impart such properties to detergent compositions, does not adversely affect the softening of hand washed laundry by the present agglomerate. Soda ash may be used in place of some or all of the sodium sulfate of the agglomerate and a good softening additive will also be obtained.

Title: Pipe fitting
Inventor: BATES JOHN RICHARD
IPC: F16L55/17
Filed: 1989-03-08
Abstract: When component "halves" of a pipe fitting are fitted together around a pipe, with respective annular seals at each end, a projecting tongue (12) formed at one side of each component engages with corresponding sockets means (17, 14) of the other component, and longitudinal sealing means are sealingly retained therebetween, e.g., in groove (15). Thus, the sealing plane is not between surfaces which abut in the direction of bringing together of the "halves" (as is conventional), but between surfaces which slide across each other in the said direction. This allows considerable variation in the relative positions of the "halves" when fitted together enabling effective sealing around a wider range of pipe diameters. <IMAGE>
