Title: An actuator for a chair adjustment mechanism lock
Inventor: HANCOCK WILLIAM JOHN
IPC: A47C1/027
Filed: 1996-02-15
Abstract: An actuator 1 for a chair adjustment mechanism lock has a first arm 10 pivoted to housing 2 and a second arm 30 pivoted on the first arm and engaging a bolt head 4 of the lock. Movement from the open position brings the arms through an in-line position to an over-centre, closed position at which the second arm 30 presses against the bolt head 4. A front face 15 and stop surface 14 define the closed position, and stop surface 13 defines the open position. In further embodiments, the actuator is latched in its closed position by a spring-biased handle; the actuator is automatically returned to its closed position by a leaf spring; the actuator comprises pivoted arms acting between the lock and a housing therefor; the arm which engages the bolt head also provides stop surfaces defining the open and closed positions.
Patent GB-2312248-A (GB)
Title: Rotary actuator
Inventor: COOK TERRY THOMAS
IPC: F15B15/04
Filed: 1996-04-17
Abstract: A rotary actuator uses a double acting piston assembly (20, Fig 1) moving in a toroidal pressure chamber to provide angular motion. A torque is developed by coupling an internal flange plate 13 to the piston. The flange plate is then used to drive a shaft 15 through a ratchet type of clutch 14. The actuator operates in various modes from fluid pressure signals. These modes may be oscillatory, continuous angular motion or step input positional. The design also allows reverse mode operation to give pressure signals out from shaft angular motion. Two actuators may be coupled to a common shaft to provide greater torque than from one actuator. A system may include two actuators connected so that torque is transformed to pressure at one location and the pressure is transformed to torque at another location.

Title: Membrane Filters
Inventor: WAKEMAN RICHARD JOHN
IPC: C02F1/36
Filed: 1996-07-18
Abstract: A membrane filter for suspensions etc., which membrane 15 can be a flat sheet or tubular (Fig 5), has a stabilised, low velocity flow preferably with flow straighteners (1, Fig 1) in a retentate chamber 3 and uses ultrasonics 19 and/or an electric field formed between electrodes 16, 17 to improve separation of the solids from the solution and migration of contaminants from the permeable membrane 15. Preferably one electrode is in the retentate chamber 3 and the other(s) behind the membrane in the permeate chamber 7. The electric field can be AC, DC, AC with a DC bias or pulsed. As an alternative, electrolysis gas products can be separated from the retentate or permeate by using separate anolyte and catholyte chambers (23, Fig 4) containing electrolyte fluid and ion permeable but liquid impermeable membranes. The filter can be a single or multiple cell, in parallel or series. Preferably the cross-flow rate is less than or equal to 1 metre per second. The solutions to be filtered can be municipal, industrial, sewage or biological broths, sludges or effluents.

Title: Temperature dependent disc drive parametric configuration
Inventor: ENARSON KARL L
IPC: G11B33/14
Filed: 1998-05-14
Abstract: A method and apparatus are disclosed to optimize operational performance of a disc drive (100) through temperature dependent parametric configuration. The disc drive is provided with a temperature sensor (160) which provides an indication of operational temperature, circuitry (152, 156) which utilizes temperature dependent parameters to optimize performance and a parametric configuration circuitry (142) which identifies a plurality of operational temperature ranges and a corresponding set of parameters for each range. Upon initialization of the disc drive (202), the parametric configuration circuit measures the temperature (204) and loads the appropriate set of parameters (206). Thereafter, the parametric configuration circuit initiates a series of delays (212, 220) and measures the temperature of the drive (219, 222) at the conclusion of each delay. When the measured temperature indicates the drive has transitioned to a new operational temperature range (216, 224), the corresponding set of parameters are loaded (218, 226).
Patent GB-2359625-A (GB)
Title: Monitoring oligonucleotide binding using chemiluminescent quenching
Inventor: RUTTER ANDREW JAMES
IPC: C12Q1/6818
Filed: 1999-12-10
Abstract: A method for detecting and/or quantifying a target nucleic acid sequence in a sample using an oligonucleotide probe is claimed. The oligonucleotide is labelled with at least one of a chemiluminescent molecule and a quencher molecule. These are arranged such that their interaction changes according to whether the oligonucleotide probe is bound to the target or not. Due to this target/probe interaction in either the bound or unbound state chemiluminescence is attenuated whilst in the other state there is no such attenuation. By changing the reaction conditions said chemiluminescent molecules may react, thereby luminescing and the target is detected. Preferred chemiluminescent molecules include acridine, phenanthridine, benzacridine, quinoline or pyridine, whilst the quencher molecule may be an azo dye. Alternatively the chemiluminescent molecule and the quencher molecule may be on separate oligonucleotide probes.
