Abstract:
A pond filter arrangement comprising a pond filter (1) comprising a housing having a fluid inlet (12) and a fluid outlet (13) and a chamber (16) within the housing holding a plurality of filter media elements (2) which is disposed in a flow path between the inlet (12) and the outlet (13). Agitation members (41) are disposed in the chamber for agitating carried filter media elements in a cleaning process. The filter media elements (2) are compressible open celled foam portions which, under action of the agitation members (41), are free to change location within the chamber and move relative to one another.
Abstract:
A spectroscopic instrument comprising a compartment (2) for housing instrument components (3) and desiccant (4) to protect the instrument components, and a deformable container (5) having at least one wall portion which is movable within the compartment (2) so as to vary the volume of the compartment (2) that is occupied by the deformable container as the container is deformed. The interior of the deformable container (5) is in fluid communication with the surroundings of the instrument, such that a difference in pressure between the compartment and the surroundings tends to cause the deformable container to deform, moving the wall portion.
Abstract:
Certain embodiments herein are directed to a differential scanning calorimeter comprising a sample holder thermally coupled to a first furnace, a reference holder thermally coupled to a second furnace, and a processor electrically coupled to the first furnace and the second furnace, the processor configured to receive data during a scan of a sample to provide a heat flow trace and further configured to subtract a calculated baseline from the heat flow trace, the calculated baseline comprising the sum of an isothermal baseline function, a scanning baseline function and a transient baseline function. Calibration methods are also described.
Abstract:
Flowline electrical impedance generation means (5) for generating a local electrical impedance in a metallic tubing portion of a flowline (21). Such means (5) may be used in place of insulation joints in various systems. The impedance generation means (5) is tuned or tuneable to achieve maximum impedance at chosen frequencies - ie frequencies which it is desired to block.
Abstract:
An aerostatic bearing spindle comprising a shaft (2) journalled within an aerostatic bearing (204), the bearing comprising at least one supply port (241) for supplying gas to generate a journal gas film between the shaft and the bearing, wherein the spindle is arranged in such a way as to cause, in use, an unequal pressure profile around the bearing for causing a damping effect to control orbiting of the shaft (2) within the bearing (204) An aerostatic bearing spindle arrangement comprising an aerostatic bearing spindle and an active control system (1001) for controlling at least one of the supply of gas to the journal gas film and exit of gas from the journal gas film to controllably alter the pressure profile around the bearing (104) in use.

Abstract:
A gas bearing spindle (2) for use in processing apparatus (1), for example ion implantation apparatus. The spindle (2) has a steel bearing surface (23) and a shaft (3) coated with chrome (3a) or another hard material.
Abstract:
Spindle speed probes (6) and spindles including such speed probes. The speed probe (6) is arranged to sense the speed of rotation of a shaft (5) making use of a magneto resistive sensor (3). The magneto resistive sensor (3) is arranged in a stack with a circuit board substrate (62), an electronics module (61) and a permanent magnet (2). An additional magnet (8) may be provided to provide additional drag to help prevent undesirable windmilling.
Abstract:
A hose reel cart comprising a main body (1) on which a drum (4) for carrying hose (5) is mounted for rotation relative to the main body, wherein a wheel arrangement (2) is provided on the main body to aid in movement of the cart over a surface and a drum lock arrangement (7, 41) is provided for locking the drum against rotation relative to the main body (1). The drum lock (7, 41) is automatic activating when the cart is in wheeling position.
Abstract:
Diffuse reflectance spectroscopy apparatus for use in analysing a sample comprising a sample receiving location (2) for receiving a sample (3) for analysis; an illumination arrangement (4) for directing light towards a received sample; a detector (6) for detecting light reflected by a received sample; and collection optics (5) for directing light reflected by a received sample towards the detector. The illumination arrangement further comprises an interferometer (42) and a half beam block (45a, 45b) which is disposed substantially at a focus in the optical path for blocking light which exits the interferometer, passes said focus, and is reflected from reentering the interferometer. A half beam block (45a) may be disposed in the optical path between the interferometer and the light source (41) for blocking light that exits the interferometer back towards the light source and is reflected by the light source from re-entering the interferometer and/or a half beam block (45b) may be disposed in the optical path on the opposite side of the interferometer than the light source.
