Abstract: A wheel assembly 10 for a golf trolley (30) comprises a wheel 12, a motor for driving the wheel, a battery 20 for powering the motor, detection means for detecting whether or not the wheel 12 is rotating, a control unit 22 for controlling the motor and releasable connection means 24 for releasably connecting the wheel assembly 10 to a golf trolley (30), the control unit 22 having at least a first mode of operation in which the motor can be activated only when the wheel 12 is already rotating.

Abstract: The invention relates to methods of preparation of highly sensitive potentiometric sensors with an electroconductive polymer film as a sensing element.

Abstract: A method of electrochemical analysis using a sensor electrode specific for an analyte under test. The method comprises immersing the sensor electrode in a sample solution suspected of containing the analyte; forming an electrochemically active complex by exposure to solutions containing secondary receptors or competing molecules labelled with a charged or enzyme label; and subsequently exposing the sensor to an electrochemically active solution. The measurement step comprises driving the sensor electrode potential to a predetermined fixed potential by applying a current or activation waveform then monitoring the potential difference between the sensor electrode and a reference electrode following removal of the holding current. Current, rate and potential can all be measured and used to determine analyte concentration or sensor state.

Abstract: An apparatus for damping torsional vibration in a shaft, having a plurality of retainer pockets spaced from each other in the direction of the shaft's axis of rotation and connected for contemporaneous rotation with the shaft, and a plurality of disks each disposed within one of the retainer pockets, each retainer pocket having a circular track wall, each disk being free to shift perpendicular to the shaft's axis of rotation to engage and move along the circular track wall in response to the vibration, wherein each circular retainer pocket has a center that is at a predetermined radial offset distance relative to the shaft's axis of rotation and the respective radial offsets are angularly spaced from each other about the shaft's axis of rotation.

Abstract: A golf bag for storing and carrying a standard set of (14) golf clubs and ancillary golf equipment and comprising a tubular housing (11, 12, 13, 14) in which is rotatably mounted a carousel (16, 17, 19) rotatable in upper and lower bearings within the housing. On the carousel clubs are mounted with their heads lowermost on a plurality of shelves (18) with their shafts located by clips (21) in individual flutes (20) in the carousel. The clubs are maintained in position within the housing and prevented from moving or clashing together. Access to the interior of the housing is by way of a hinged door (15), and the interior of the carousel provides a storage compartment. Housing the clubs with their heads lowermost lowers the centre of gravity of the bag, and a detachable carriage (38,39) and optional tractor unit (42) are provided.

Abstract: Perfluorocarbon polymer-based matrices are coated with a hydrophilic polymer for use in bioaffinity separations. Coating is carried out by dispersing porous particles of inert perfluorocarbon polymer in a water-miscible organic solvent such as acetone or tetrafydrofuran to wet surfaces of the particles, forming a dispersion of the wetted particles in an aqueous solution of hydrophilic polymer such as poly(vinyl alcohol) containing a plurality of hydroxyl groups, at least one being at an end of a polymer chain, to adsorb the hydrophilic polymer onto the wetted surfaces of the particles, admixing a homobifunctional cross-linking agent such as glutaraldehyde with the particles to cross-link the hydrophilic polymer, activating hydroxyl groups on the surface of the cross-linked hydrophilic polymer and covalently bonding a ligand or ligand binder to the activated hydroxyl groups.

Abstract: Disclosed is an improved solar energy collection device and method of making the device. A low shear strength solid, a thixotropic or approximately solid coagulum of black energy absorbing material is used to fill an open topped insulated tray, the top of which is glazed with one or more panels of light transmissive material. A heat transfer tube means is embedded in the coagulum of black material in the tray to promote efficient heat transfer to the secondary or storage fluid circulating within the tubing. Increased active heat transfer surface area is achieved by embedding the tubing directly and completely in the coagulum of black absorber material in the tray. The light transmissive glazing material may be in contact with the black coagulum absorption material to reduce convection, reflection and radiation losses back to the atmosphere. The light transmissive cover also acts as a contaminant shield for the coagulum or primary body of energy absorbing material.

Abstract: A rotating lamp fixture includes a plurality of lamps, attached to an arm which extends outwardly from a housing preferably mounted to the ceiling of a building. The arm is connected through a torque coupling and a gear train to the shaft of an electrical motor. The motor imparts a relatively slow circular or orbital motion to the lamps through the arm for serving as an artificial light source. The provision of a rotating light source reduces by at least one-third the number of fixed light sources needed for effectively controlling the growth of vegetation. The rotating lamp fixture increases the growth rate, improves the uniformity of growth, and/or precisely controls one or more other growth characteristics of the vegetation. Other features are also disclosed.
