Title: Backflow prevention for high pressure gradient systems
Inventor: RICHARDSON HAL
IPC: G01N30/36
Filed: 2003-12-02
Abstract: Gradient performance with high pressure gradient solvent delivery system is optimized by approximation of infinite stroke volume of high pressure pumps (105,122) by the addition of pulse dampening with backflow prevention to each high pressure pump (105, 122). The backflow prevention adds sufficient minimum flow resistance, thereby enhancing the performance of the pulse dampening over a wider range of flow rates -resulting in consistent gradient performance.

Abstract: A fastener placing tool for placing fasteners of the breakstem blind rivet type which comprise a shell and a mandrel to which a progressively increasing relative force is applied to progressively move the relative positions of the mandrel and shell thereby to deform the shell. The tool comprises a shell-contacting anvil 18, a mandrel-gripping jaw assembly 17, and a hydraulic piston 16 for applying a progressively increasing force to the jaw assembly 17 with respect to the anvil 18, thereby to progressively move the mandrel with respect to the shell. The fastener placing tool incorporates a force/stroke monitoring device 22 which comprises an assembly body 24 detachably mounted on the tool between the latter and the anvil 18, a load-cell sensor 33 carried by the assembly body 24 for sensing the force applied by the hydraulic piston 16 to the jaw assembly 17 with respect to the anvil 18, and a non-contact stroke-sensor 35 carried by the assembly body 24 for sensing the position of the jaw assembly 17 relative to the anvil 18. The stroke-sensor 35 operates without physical contact with the jaw assembly 17 or any part of the tool moving therewith. To this end the jaw assembly 17 is connected to the hydraulic piston 16 by means of an adaptor tube 23 which has a conical tapering outer surface. The clearance distance between the sensor 35 and the adjacent part of the conical surface of the adaptor tube 23 varies with the axial position of the adaptor 23 and jaw assembly 17.

Title: Security in data communication
Inventor: MORRIS STUART
IPC: G06Q20/00
Filed: 2005-07-07
Abstract: Secure communication wherein an image specific to a user is displayed before sensitive information is entered. A log-on page specific to the user may be generated at the terminal so the user can distinguish between a valid log-on page/Webpage issued e.g. by a bank and a phishing Webpage. Also In an exchange of data between a client terminal, e.g. ATM (1, Fig. 1) and a secure database server (2, Fig. 1) the data is encoded using positional information generated by a combination generator in a separate security server (3, Fig. 1). The positional information is used to produce an image specific to a communication event which is accessed by the client terminal and is the basis for the entry of sensitive data (e.g. password or PIN data) at the client terminal. The image might be a keypad having alpha-numeric characters or symbols, whose positions are changed according to a random string (Figs 3, 6 and 7). The three-way communication link between the client terminal, database server and security server increases the difficulty of successfully intercepting and decoding the data entered at the client terminal.

The guide films may be coloured and may be cut from the paperboard by a trimmer set 70 located downstream from the cooling rollers. The guide films ensure that the layer 20 does not shake and shift so that a thin and even layer of bio-degradable material can be spread on the paperboard. The bio-degradable paperboard may be used for food containers.

Title: Resonant discontinuous forward power converter
Inventor: RUSSELL JACQUES
IPC: H02M3/335
Filed: 2008-06-20
Abstract: A discontinuous resonant forward converter comprises a polarity matched transformer 206, a switch such as MOSFET 212, an output rectifier such as diode 220 and a smoothing capacitor 222. Switch controller 210 is configured to control the timing of switch 212 such that current only flows to the smoothing capacitor 222 at node X when switch 212 is on and substantially no current flows to the output during a resonant period when switch 212 is off. A small secondary inductor (fig 5c) may contribute to current limiting and a free-wheel rectifier is not necessary. The length of duty cycle is preferably such that the off period includes half a cycle of sinusoidal resonance to reset transformer 206. The duty cycle or frequency are fixed but also can be controlled in response to inputs of the energy level in transformer 206, the primary voltage, an auxiliary winding (fig 6a) voltage, the current through switch 212 and whether operation in a current limiting mode, a standby power mode or mains ripple rejection is required. During start up the frequency may be increased and the converter operated in a non-resonant mode. Current limiting may be achieved by pulse width modulation. In a standby mode switch pulses may be omitted or skipped. The control circuit can be implemented on a single integrated circuit and provides zero volt switching, improved start up, current limiting and regulation, and alleviates the effects of component tolerances in the resonant circuitry.
