摘要:
The present invention is directed to novel biocatalytic processes for the conversion of aliphatic ∝, ω-dinitriles into the corresponding ω-nitrilecarboxylic acid. More particularly, the present invention provides a method for the conversion of 1-cyanocyclohexaneacetonitrile to 1-cyanocyclohexaneacetic acid using an enzyme catalyst with nitrilase activity. 1-cyanocyclohexaneacetic acid is a useful intermediate in the synthesis of gabapentin.
摘要:
A radiotherapy apparatus comprises a first collimator and a second collimator, the first collimator being a multi-leaf collimator, the second collimator comprising a plurality of slits having a width which is a fraction of the width of the leaves of the first collimator, the first and second collimators being aligned such that each slit of the second collimator is associated with a leaf of the first collimator. A first irradiation is made, during which the first collimator will define the outer edge of the irradiation pattern, and the second collimator will serve to narrow the effective width of each leaf of the first collimator. This narrowing is a simple function of the relative widths of the slits of the second collimator and the leaves of the first. This will leave gaps in between the slits of the second collimator, which can then be filled by moving one or more of the patient, first and second collimators, so as to irradiate an area omitted in the first irradiation. In this second irradiation, the positions of the leaves of the first collimator are adjusted as necessary. This process is then repeated until the entire target area has been irradiated. Suitable values for the fraction are {fraction (1/2, 1/3, 1/4)}, or ⅕.
摘要:
A pucker free garment seam providing a garment with a tailored and wrinkle free appearance. The pucker free seam and method for production utilizes a bonding strip which contains at least a thermal adhesive component which is inserted between first and second garment components sewn together along the seam. A sufficient amount of heat and pressure is applied to the seam which causes the adhesive of the bonding strip to flow onto the surfaces of the garment components and into interstices thereby creating a seam and permanently bonding the first and second garment components together along the seam to eliminate puckering associated with shrinkage of the sewing thread.

A pucker free garment seam providing a garment with a tailored and wrinkle free appearance. The pucker free seam and method for production utilizes a bonding strip which contains at least a thermal adhesive component which is inserted between first and second garment components along the seam and a sewing thread is used to bind the components together into a seam. A sufficient amount of heat and pressure is applied to the seam which causes the adhesive of the bonding strip to flow onto the surfaces of the garment components thereby creating a compressed seam and permanently bonding the first and second garment components together along the seam to eliminate puckering associated with shrinkage of the sewing thread.

A pucker free garment seam providing a garment with a tailored and wrinkle free appearance. The pucker free seam and method for production utilizes a bonding strip which contains at least a thermal adhesive component which is inserted between opposing surface of a garment component along the seam. A sufficient amount of heat and pressure is applied to the seam which causes the adhesive of the bonding strip to flow onto the surfaces of the garment component thereby creating a compressed seam and permanently bonding the surfaces of the garment component together along the seam to eliminate puckering associated with shrinkage of sewing thread at the seam.
摘要:
A computer system having a processor and at least one peripheral has a programmable shared memory system and method that selectively dedicates a first potion of memory to use by the processor and allocates a second portion of memory to shared use by the processor and any peripherals in the system. The programmable memory architecture is implemented using a dual bus architecture having a first-bus connected to the processor and a second bus coupled to the processor by a system controller and to the peripherals by a peripheral controller. The programmable memory architecture additionally has a configuration controller coupled to each configurable memory bank in the system. Each configuration controller is additionally coupled to both the first and second buses. Under programmed control, the each configuration controller couples the associated memory to either the first or second bus, responsive to configuration information stored in the system controller. Memory coupled to the first bus operates as dedicated processor memory and memory coupled to the second bus operates as shared memory, accessible by the processor and any peripherals in the system.
