摘要:
A timepiece, time display, and method of presenting time information. The timepiece includes clock means for measuring the passage of time in standard units, and maintaining a current value. A visual display is included for displaying one of the standard units of the current value at a time. The time piece further comprises means for selecting one of the standard units and presenting the selected unit of the current value on the visual display. The current value is represented by the position of an indicator within a defined space on the visual display.

A Radiation Curable Coating composition, which may be used as an inner primary coating, an outer primary coating, single coats, a matrix, or a buffer resin composition, comprising: A Radiation Curable Coating composition, which may be used as an inner primary coating, an outer primary coating, single coats, a matrix, or a buffer resin composition, comprising at least one radiation-curable oligomer wherein said at least one radiation curable oligomer is a fatty-acid modified epoxy acrylate; at least one ethylenenic unsaturated reactive diluent; wherein said oligomer(s) and diluent(s) are selected from the group that does not include moieties with Urethane chemistry. This composition, when tested, is found to have resistance to thermal degradation as measured by less than 10% weight loss after exposure of cured specimens in a natural convection furnace for 100 hours at 180° C.

A hybrid drive system comprising: an internal combustion engine having a first output shaft; an electric motor having a second output shaft coupled to the first output shaft, the motor being capable of operating in a drive mode to drive the second output shaft and in a regeneration mode to generate electricity from the motion of the second output shaft; a gearbox having an input shaft coupled to the first and second output shafts and an output shaft coupleable to the input shaft in any of two or more gear ratios; a control unit arranged to control the electric motor during the changing of the gearbox from one gear ratio to another so as to alter the speed of the input shaft so as to match that of the output shaft for the said other gear ratio.
摘要:
A welding face covering such as a digital welding helmet includes a face protector which would be located in front of the welder's eyes. The inner surface of the face protector has a digital viewing screen. A digital lens is mounted externally of the face protector for viewing the welding site. The digital lens transmits an image of the welding site to the viewing screen. As a result, the welder can view the welding site by looking at the screen rather than looking through a viewing window of the face covering or helmet.
摘要:
A radiation curable coating composition for an optical fiber comprising: at least one urethane(meth)acrylate oligomer, at least one reactive diluent monomer and at least one photo initiator is described and claimed. The composition is capable of undergoing photopolymerization when coated on an optical fiber and when irradiated by a light emitting diode (LED) light, having a wavelength from about 100 nm to about 900 nm, to provide a cured coating on the optical fiber, with the cured coating having a top surface, and the cured coating having a Percent Reacted Acrylate Unsaturation (% RAU) at the top surface of about 60% or greater. Also described and claimed are the process to coat an optical fiber with the LED curable coating for optical fiber and a coated optical fiber where the coating has been cured by application of LED light.
