Patent GB-2432846-B (GB)
Title: Medium and culture of embryonic stem cells
Inventor: THOMSON JAMES A
IPC: C12N5/00
Filed: 2005-09-08
Granted: 2009-12-30
Abstract: Previous methods for culturing primate pluripotent stem cells have required either fibroblast feeder cells or a medium which was exposed to fibroblast feeder cells to maintain the stem cells in an undifferentiated state. It has now been found that high levels of fibroblast growth factor in a medium together with at least one of gamma aminobutyric acid, pipecolic acid, and lithium, enables pluripotent stem cells to remain undifferentiated indefinitely through multiple passages, even without feeder cells or conditioned medium. Without beta-mercaptoethanol, the medium improves cloning efficiency. Also, a matrix of human proteins can be used to culture the undifferentiated cells without exposing the cells to animal products. Further disclosed are new primate pluripotent cell lines made using the defined culture conditions, including the medium and the matrix. Such new cell lines will have never been exposed to animal cells, animal products, feeder cells or conditioned medium.

Abstract: Portable tester and method for testing a variety of circuit boards without utilizing adaptor boards for re-routing input test signals and supply voltage from the tester to pins of the board under test. A plurality of edge adaptors having different pin spacings have their respective pins connected in parallel to corresponding edge connector stake pins. Each edge connector stake pin is connected to or isolated from the corresponding driver/sensor stake pin by means of a switch. Each driver/sensor stake pin is connected to the input/output terminal of a programmable driver/sensor circuit. A plurality of power supply stake pins are connected to various power supplies of the portable tester. Connectors coupled to the family board can be utilized to route power supply voltages to electrically isolated edge connector stake pins. Isolated driver/sensor outputs can be routed to other edge connector stake pins. A main processor stores a test program and transmits data and control information to predetermined driver/sensor circuits. A high speed processor is coupled between the main processor and the inputs of the driver/sensor circuits. The high speed processor memory can store a bus-defining subroutine containing a sequence of data shifting instructions which shift a word in the shift register to the input of specified driver/sensor circuits at high speed. The high speed processor can synchronize the operation of the portable tester with an asynchronously operating printed circuit board under test.

Title: A mass flow sensor
Inventor: DAMES ANDREW NICHOLAS
IPC: G01F1/78
Filed: 1989-12-18
Granted: 1992-10-28
Abstract: A coriolis-type mass flow sensor (10) suitable for aerospace use comprises a turning fork (14) which is immersed in the fluid whose mass flow is to be sensed, such that its vanes extend across (ie perpendicular to) the direction of flow of the fluid. The whole tuning fork is elongated in the direction of flow of the fluid, so that the fluid flows over (and between) the vanes: typically, the fork may be up to 15 cm long in the direction of flow. The vanes are excited to vibrate perpendicularly to the direction of flow of the fluid by several piezoelectric drive devices held under compression in, and distributed symmetrically about the midlength of, the yoke (12) from which the vanes project, while the vibrations are sensed by respective piezoelectric pickup devices within each end of the yoke. The phase difference between the vibrations sensed by the two pickup devices is a function of the mass flow of the fluid. In an alternative form, the sensor has two pairs of vanes symmetrically distributed around the yoke as a kind of double tuning fork, while in another alternative form, the vanes are formed integrally with, and project into, a short section of cylindrical pipe.

Title: Modification of metal surfaces
Inventor: ZHAO QI
IPC: B01J19/00
Filed: 1995-11-02
Granted: 1999-06-23
Abstract: A method of maintaining a high value of heat transfer coefficient for a metal heat transfer surface in which the surface energy of the heat transfer surface is reduced by ion implantation or other surface modification techniques. The reduction in surface energy of the heat transfer surface delays the onset of scale formation and additionally reduces the adherence of any scale formed to the metal surface. Besides ion implantation, the energy may be reduced by magnetron sputter ion plating or plasma enhanced chemical vapour deposition (PECVD). A combination of these techniques may be used. Implanted ions include Cr + , F + , C + , H + , N + or SiF 3  + , the C + and F + being obtained from PTFE. Materials deposited by PECVD include Si 3 N 4 , Si, SiC, hexamethyldisalazane, tetraethylorthosilicate, or trimethylvinylsilane. As illustrated in Fig 5 dynamic mixing ion implantation may be used where two or more species of ion are simultaneously implanted.
