Abstract:
Production of coke and activated carbon from coal products, including the production of low ash coal and activated carbon products from coal products, and the production of very low ash coke and activated carbon products from coal products.
Abstract:
Methods are provided for converting into a sequence specific strand specific and location specific DNA nicking endonuclease, a restriction endonuclease that recognizes an asymmetric DNA sequence, the endonuclease having two catalytic sites and one or more single sequence specific DNA-binding domains. In one embodiment the method requires inactivating one of the catalytic sites of the restriction endonuclease. In another embodiment, the restriction endonuclease is a dimer having a first and second subunit each comprising a sequence specific DNA binding domain, a catalytic site and a dimerization domain. The nicking endonuclease is formed from combining one subunit having an inactivated catalytic site and a second subunit having an inactivated DNA binding domain. The nicking endonuclease may be converted into a restriction endonuclease by the addition of manganese cations in the digestion buffer.
Abstract:
A manipulator for manipulating metal ingots comprises a wheeled carriage (3, 103) with a peel assembly (1, 101) supported on it so that the peel assembly can move relative to the carriage. The peel assembly is supported adjacent one end of the carriage by at least one piston-cylinder device (53, 152) and a plurality of elongate links (66, 69, 169, 170) are pivotally coupled to the peel assembly and to a rigid support means (65, 165, 166, 167) on the carriage away from the end.
Abstract:
A medical implant can include a bioerodible metal portion and a coating overlying the bioerodible metal portion. The coating can include a therapeutic agent and a polysaccharide matrix reversibly cross-linked with polyvalent metal cations. Upon implantation of the implant within a body, the therapeutic agent is released and the bioerodible metal portion erodes to release polyvalent metal cations capable of re-cross-linking the polysaccharide matrix.
Abstract:
A rugged resonator for a laser includes a laser pump housing. An X-fold resonator assembly is configured to receive and hold the laser pump housing. The resonator includes at least four mirrors, a first, a second, a third, and a fourth mirror. The first mirror is configured to receive a first incident laser beam from the first end and to reflect a first reflected beam to reflect as a third reflected beam from the third mirror. The second mirror is configured to receive a second incident laser beam from the second end and reflecting a second reflected beam to intersect the first reflected beam and to reflect as a fourth reflected beam from the fourth mirror. An optical coupler is affixed to an optics plate and configured to receive the fourth reflected beam. A high reflector is affixed to the optics plate and configured to receive the third reflected beam.
Abstract:
A golf club comprises a shaft (3) and a club head (2) which is connected to a shank portion (4) of the shaft at its heel end (31) so that it can be rotated around the axis of the shank portion. The configuration of the shank portion is such that the shaft axis and the shank axis intersect at about the bottom of the heel end of the club head so that rotating the club head around the shank axis causes the angle between the club face (30) and the shaft (3) to change.
Abstract:
A coiled sheath (10) for electrical cords is formed of polyethylene tube drawn from a supply (20). The tubular body (10) is drawn through a bath of glycerine at, e.g. 125 DEG C and a slit is formed in the tubular body (10) by a knife (22). A continuous core (24) is inserted through the slit in the tubular body (10) and the body (40) is wound around the mandrel (25) at least three times before the core (24) is stripped. The body (10) is passed around the mandrel (25), which is in a cold water bath (26) at least one more time and is then cooled in the opposite direction before being cut to predetermined lengths by a docking knife (27).
Abstract:
A pressing machine for reducing the width of a hot metal slab has a pair of platens which are caused to engage with opposite edges of the slab to apply forces which reduce the width of the slab. This pressing action may cause buckling of the slab and to prevent, or at least reduce, the buckling, one or both of the opposite faces of the slab has a restraint provided adjacent thereto. The restraint may be in two parts connected to respective platens and arranged to allow for movement of one platen with respect to the other platen.
