Abstract: An energy storage system having a first, gravity-based energy storage sub-system having at least one weight movable between a first upper position and a second lower position defining a vertical displacement and a second energy storage sub-system comprising a vessel for storage of a pressurized fuel gas has an electrical input/output connection with an external power system and at least one of: a fuel gas inlet for supply of a fuel gas to the energy storage system from an external fuel gas supply or network; and a fuel gas outlet for supply of a fuel gas from the energy storage system to an external fuel gas user or network, and/or has at least one of: a gas to power conversion arrangement for converting energy from fuel gas to electrical energy for storage in the first energy storage sub-system or export to an external power system via the electrical output connection; and a power to gas conversion arrangement for converting electrical energy to a fuel gas for storage in the second energy storage sub-system

Abstract: A fining package for a glass composition may include a sulfate or a sulfide in an amount from about 0.001 to about 1 mol % of the glass composition. The fining package may include a multivalent compound, such as CeO2, SnO2, or Fe2O3, in an amount from about 0.001 to about 1 mol % of the glass composition. The fining package may be sulfide-free. The fining package may be free from a reducing agent for reducing sulfate to sulfide. The fining package may be free of at least one of Cl, F, Sn, Ce, and As. The glass composition may be used to form glass tubing. The glass tubing may be used to form a pharmaceutical packaging.

Abstract: The present disclosure relates to novel vascular endothelial growth factor receptor (VEGFR)-binding polypeptides and methods for using these polypeptides to inhibit biological activities mediated by vascular endothelial growth factors (VEGFs). The present disclosure also provides various improvements relating to single domain binding polypeptides.

Abstract: A polymeric film has a substrate layer of polyester material and an antistatic layer containing a polyester/polyalkylene oxide copolymer and a salt, the ratio by weight of copolymer/salt being in the range from 0.1 to 100/1. The copolymer is preferably a polyethylene terephthalate/polyethylene oxide block copolymer and the salt is preferably an alkali metal salt. The film exhibits low surface resistivity, even at low relative humidity.

Abstract: A polymeric film has a polyester substrate layer and a cross-linked adherent layer of an acrylic resin and a phthalate ester. The adherent layer exhibits improved adhesion to the substrate and to a range of subsequently applied layers, such as inks, lacquers, and vinyl chloride polymers.

Abstract: The invention relates to apparatus for measuring blood pressure by providing an inflatable cuff and pulse sensing means for fixing to a digit such as, for example, a finger or toe, and electrical control circuit means for converting a sense pulsed into a visual or audible indication, pneumatic means for transmitting the sensed pulse to the converting means and pressure means for measuring the pressure exerted in the cuff, the arrangement being such that with the cuff in a operative position on the body, progressive inflation/deflation of the cuff is effected until pulse sensing means just detect the presence of the pulse thus providing an indication of the systolic blood pressure.

Abstract: A circuit protection device comprising a chalcogenide glass threshold switching element connected or arranged to be connected between a current carrying line and earth, and a capacitor connected in a series with the switching element.

Abstract: An arrangement for protecting an electrical circuit from a voltage transient having a fast rise time, e.g. in the order of 20 Vns.sup.-1 comprises a number of semiconductive threshold foldback switching elements preferably formed from a chalcogenide glass, in parallel with one another between the current carrying line of the circuit and earth. An additional, non-linear, circuit protection device is connected in parallel with the switching element between the current carrying line and earth, in order to pass high frequency components of the transient to earth.

Abstract: An arrangement for protecting an electrical circuit from a voltage transient having a fast rise time, e.g. in the order of 20 Vns.sup.-1 comprises a number of semiconductive threshold foldback switching elements, preferably formed from a chalcogenide glass, in parallel with one another between a current carrying line of the circuit and earth. One or more capacitors are connected in series with the switching elements between the current carrying line and earth in order to prevent any direct currents in the current carrying line holding the switching elements in their low resistance state.

Abstract: A turbine lubricant having outstanding oxidation stability, corrosion resistance and good viscosity stability is based on an alkyl phenyl phosphate ester and contains small amounts of benzotriazole, a mixed mono- and dialkylphosphate of the formula RH.sub.2 PO.sub.4 and R.sub.2 HPO.sub.4, wherein R is an alkyl group of 8-12 carbon atoms, and an antioxidant selected from the group consisting of:(a) a C.sub.12 to C.sub.18 alcohol ester of 3,3'-thiodipropionic acid;(b) pentaerythritol tetra(3,5-di-tert-butyl-4-hydroxyphenyl)propionate, and(c) 4,4'-thiobis-(3-methyl-6-tert-butylphenol).

Abstract: Tributoxyethylphosphate is useful in controlling foam produced during the evaporative crystallization of calcined trona solutions. The chemical is effective at low concentrations, i.e. 1 to 30 ppm, and does not significantly alter the crystal habit of the sodium carbonate crystals.

Abstract: A human ventilatory capacity measurement instrument, of the kind which measures the peak flow rate of a single forced expiration, comprises a hollow cylindrical body housing a coaxial rod on which is carried a piston spring-biased in one longitudinal sense. The body is longitudinally slotted and has an indicator engaged in the slot for movement therealong by the piston when blown against its spring bias, but the indicator is returned to its starting position in the slot by independent movement. A scale is provided alongside the slot to give a measure of peak flow rate by the final rest position of the indicator when pushed by the piston.

Abstract: Apparatus for detecting alcohol vapour in a gas, such as exhaled breath. The apparatus comprises a detachable mouthpiece through which a person exhales. The mouthpiece includes a vent for venting some exhaled breath to atmosphere and an outlet port connected to a sensor which provides an electrical output dependent upon the amount of alcohol in the breath sample. A piston and cylinder valve assembly is provided for introducing a predetermined amount of the sample into the sensor at a time dictated by an operator. A calibrated meter, which may be analogue or digital is connected to the sensor to indicate the amount of alcohol in the sample.
