Title: Computer-implemented system and method suitable for increasing the security of instant off-line blockchain transactions
Inventor: WRIGHT CRAIG STEVEN
IPC: H04L9/00
Filed: 2019-03-25
Abstract: This specification describes a system and method that enables bitcoin signed transactions to be accepted as a payment for goods and services instantly and off-line, without the need to wait for confirmation that the transaction is included in a valid block, or even for confirmation that a transaction has been received by the network. Building on the concept of a one-time signature implemented within bitcoin script, this method involves a payer providing the payee with a special compensation key at the point-of-sale which can be used to claim a time-locked deposit output when combined with a 'revealed' private key, if (and only if) a double-spend is perpetrated by the payee. The validity of this compensation key is guaranteed via a novel type of zero-knowledge-proof, which is highly efficient: the proof can be generated in ~ 5 milliseconds and can be verified in ~30 milliseconds. The use of this system in a retail setting would allow vendors to accept instant cryptocurrency payments off-line for high value items without aggregated risk of loss, and without the need to trust a third party service.

Patent EP-0137696-A3 (EP)
Title: Method and apparatus for measuring water content
IPC: G01N21/35
Filed: 1984-08-29
Abstract: A modified infra-red scanning gauge used in measuring the moisture content of a paper-web during manufacture or when subject to a coating practice, has a measurement channel (216) and a reference channel (218). The measurement channel is based on the infra-red absorption spectrum of water which has an absorption band centred on 1.94 microns. The reference channel is conventionally at a wavelength of 1.83 microns (Figure 2A) where water has previously been considered to be transparent to infra-red or at a wavelength of 1.68 microns. The gauge is intended for measurement of high water content, where at 1.94 microns absorption effectively becomes total thereby preventing measurements being made, and uses a narrow-band filter (222'A) of 0.03 micron wavelength offset from the peak of the 1.94 micron absorption band in the range 1.76 to 1.87 microns, previously considered stable as regards water content but now disclosed as showing a water-dependent variation at high water contents, In a specific example a 1.83 micron filter (222A) is used for the measurement channel (218) and a 1.68 micron filter (224A) for the reference channel (218). The modified gauge which may be of the transmission or scatter type has particular use at the wet end of a paper-making machine (Figure 1).

Abstract: A molded tethered safety closure device for use on bot­
tles (12) containing pressurized liquids such as champagne or 
sparkling wines comprising a cork or closure element (14) and 
a retainer collar (16) joined by an intercoupling section (18). 
The intercoupling section is comprised of a tabbed tear strip 
(26) and a tether strip (28) that are integrally formed in a helical 
configuration extending from the cork (14) to the collar (16). 
The tether strip and the tear strip are interconnected by a pair 
of grooved frangible webs (30, 32) that can be torn by pulling 
on the tear strip. This allows the tear strip to be manually re­
moved from the intercoupling section. Following removal of 
the tear strip, the helical tether strip (28) interconnects the 
cork (14) and the retainer collar (16), thus enabling the cork to 
be released from the bottle without flying free.
