Abstract: A process and apparatus for electrolyte solution production can be provided so that a modular production can be provided. The modular electrolyte production can be provided so that the production system is mobile for being used in multiple different plants at different geographical locations that are remote from each other. Embodiments can be configured so that electrolyte production is made for a plant specific application that provides an electrolyte solution having a pre-selected concentration of at least one electrolyte for use in at least one electrolyzer of the plant. The production can be mobile so it can be provided at different sites to make the same type of solutions or different solutions specific to the needs of the plants it may support. Some embodiments can utilize an electrolyte material handling device that also modular and mobile. Other embodiments can be configured to utilize an on-site electrolyte material handling device.

Abstract: A lining for a compressor case is provided. The lining comprises a layer of primer applied to an interior surface of the compressor case, and at least one layer of a seal compound applied to the layer of primer. The primer has been found to significantly improve the bond strength between the base metal and the coating. Also, the primer provides a waterproof coating at the bond interface, which prevents any moisture from creeping under the plastic and causing material break-out. The waterproof coating also provides an increased corrosion resistance to the base metal and stator vanes where the plastic lining has been applied. A method of lining a compressor case is also provided, comprising applying a first layer comprising a primer to an interior surface of the compressor case, and applying at least one second layer over the first layer of primer, the at least one second layer comprising a seal compound to line the compressor case.

Abstract: A soap dispenser holder (10) for supporting a dispensing bottle (11) comprising a body (12) securable to a vertical surface (18). A protruding portion (20) extends outwardly from a first surface (13) of the body (12) having an outer concave surface (22) into which is received an edge of a cap (24) of the dispensing bottle (11). A lip portion (23) is provided along a lower edge of the concave surface (22) to engage with a lower edge of the cap (24). A flexible strap (14) is provided having a first end secured adjacent a first side of the outer concave surface (22) and a second end securable adjacent a second side of the outer concave surface (22) such that the flexible strap (14) is securable around the cap (24) of the dispensing bottle (11).

Abstract: The invention describes a radiation-curable ink jet ink, which comprises at least 50% by weight of cyclic trimethylolpropane formal acrylate (CTFA), and further comprises a free-radical photoinitiator, and which is substantially free of volatile compounds.

Abstract: The present invention provides a low frequency acoustic transducer for non-destructive testing of a test structure. The transducer is arranged for conversion between electrical energy and acoustic energy associated with an acoustic wave propagating through a portion of the test structure. The transducer comprises a bending actuator for generating the acoustic wave by generating a vibration from an electrical signal or for generating an electrical signal from a vibration generated by the received acoustic wave. The bending actuator has a vibration surface and a contact area surrounded by a portion of the vibration surface. The transducer further comprises a mode setting member that has a rigid portion which is in direct mechanical contact with the bending actuator at the contact area such that, within the contact area, an amplitude of the vibration is substantially suppressed. The location and shape of the contact area determine a bending mode associated with a resonance frequency of the bending actuator.

Abstract: The invention relates to a process of ink jet printing which comprises the steps of printing an ink onto a substrate and curing the ink using radiation from an LED. The invention also relates to a cationic ink jet ink for use in such a process, the ink comprising a cationically curable component including at least one oxirane, cyclic ester or cyclic carbonate monomer and a photoinitiation system including an iodonium salt photoinitiator and a sensitizer, the photoinitiation system being able to absorb radiation at a wavelength in the range of from 300 nm to 420 nm.

Abstract: A liquid flow meter for directly measuring the velocity of a liquid is disclosed. The liquid flow meter includes a pair transducers arranged facing each other in a conduit through which the liquid flows. The liquid flow meter also includes a transmitter means for causing the transducers to simultaneously transmit an acoustic wave packet directed for reception at the other transducer. A differential receiver means is also included whereby the differential receiver means has inputs each coupled to a corresponding one of the transducers for detecting an acoustic signal received thereby and determining a difference between the two received signals. The difference being related to the velocity of the liquid within the conduit. The transmitter means and the differential receiver means are each matched to the transducers to ensure substantial reciprocity to thereby substantially avoid phase and/or amplitude variations in the received signal. A method for measuring the velocity of a liquid is also disclosed.
