In one embodiment the present invention provides a coated substrate comprising a substrate, a radiation-cured coating or a thermally-cured on at least a portion of the substrate, wherein the coating comprises an inherent macroscopic texture. In another embodiment, the present invention provides a pre-cured coating mixture comprising a radiation-curable resin and an initiator, or a thermally-curable resin and thermal initiator, wherein the radiation- or thermally-curable resin and the respective initiator form a pre-cured coating mixture capable of forming a macroscopic texture upon application of the mixture on a substrate. In another embodiment the present invention provides a pre-cured coating mixture comprising a radiation- or thermally-curable resin, an initiator, and texture-producing particles having an effective size to provide a macroscopic texture upon application of the mixture on a substrate. In another embodiment, the present invention provides a coated substrate comprising a substrate and a radiation- or thermally-cured coating on at least a portion of the substrate, wherein the coating comprises an inherent macroscopic texture. In addition, the present invention provides a process for making a coating on a substrate, comprising the steps of distributing a pre-cured coating mixture comprising a radiation-curable resin and an initiator or a thermally-curable resin and thermal initiator over at least a portion of a substrate to form a pre-cured coating having a macroscopic texture, and radiation-curing or thermally curing, respectively, the pre-cured coating to form a radiation-cured or thermally-cured coating having the macroscopic texture.
摘要:
A system involving a central computer (2) and a remote computer (3), which can communicate over a link (1), is migrated from in-clear working to encrypted working automatically as the computers receive and install long term keys necessary for encrypted communication. When migration is required, the settings at both ends of the link need to be changed to “encrypt” simultaneously and, particularly, if there are numerous remote computers and the possibility of connection of a remote computer to different central computers, as is possible in virtual private network (VPN) scenarios, severe problems can ensue. Hence, as well as the normal two modes of working “in-clear” and “encrypt”, a third mode in which “initiate encryption” is set at one end of the link and “accept encryption” is set at the other end of the link is proposed. This third mode ensures that working in-clear can continue over a particular link, such as between a particular VPN server and a particular gateway PC, until a long term key required for encrypted working is installed at both ends of the link, but that once key installation is complete, only encrypted working is possible over that link.

Business data flows from one computer system (1) to another (2) and its integrity can be protected by cryptographic means, such as digital signatures. In particular, a source system (1) may use a private key (DSPR) to sign outgoing data, and a destination system (2) may use a public key (DSPU) to verify incoming data. For security purposes all keys should be changed at scheduled times calculated using factors including key lifetime (from which is calculated the key expiry time) and key delivery time. If a key is compromised it needs to be changed at other than the scheduled time, and in general this will result in calculation of a new scheduled key change time. If a DSPR key is delivered to the source system (1) encrypted by a key encryption key (KEK), then change to the KEK key will in general also be needed upon compromise of the DSPR key. A new key changetime calculation can be avoided if another public key/private key pair is pre-generated and the public key part pre-supplied to the destination system (2), where it is stored as a spare. When the existing private key (DSPR) is compromised, the new private key corresponding to the spare is supplied to the source system (1) and can be put into use immediately. In this case the expiry time of the spare public key will be substantially the same as that of the original public key, as it will deemed to have been in use as of delivery, and recalculation of the key changetime will not be required. Preferably a public key in use at the destination system (2) is not revoked immediately upon compromise of the corresponding private key, in order to enable messages signed by that private key to be verified at the destination system, using the corresponding public key, during a predetermined time interval (message latency) after signing. A maximum value for the message latency may be set and used as another factor in the scheduled key change time calculation.
摘要:
An improved musical instrument string combines the attributes of superior corrosion resistance, low stiffness, low tension at pitch, and long life during storage and end use. The potential for galvanic coupling between the winding and core of wound strings is minimized, or eliminated through the use of a cathodic core, which is preferably comprised of a titanium alloy; and metal windings of either titanium, nickel, a nickel alloy, or a surface modified copper alloy, where the preferred surface modifier is a compound from the azole family. The resultant strings are lower in stiffness, and impart a lower cumulative tension on stringed instruments when compared to conventional metallic strings. The ends of the strings, including both ends of the wound strings, as well as one end of the non-wound strings, are preferably encapsulated with polymeric sheathings to maintain winding tightness over time, to maintain tuning at pitch, to maintain sound quality over time, and to protect the instrument bridge from excessive wear during end use. Preferred polymeric sheathings, such as polyvinylidene chloride or nylon, are used outside the speaking length of the string, so as not to dampen or modulate the tonal characteristics of the string during its vibration.

An improved musical instrument string combines the attributes of superior corrosion resistance, low stiffness, and long life during storage and end use. Superior corrosion resistance is achieved through surface treatment of wound strings with an organosilane compound, where the preferred winding is a copper alloy such as phosphor bronze, and the preferred organosilane surface treatment comprises an aminotrialkoxysilane such as N-2-aminoethyl-3-aminopropyltrimethoxysilane.

A method of applying an adhesive to a substrate is comprised of supplying a liquid adhesive composition, exposing the liquid adhesive composition to an increased temperature sufficient to form a molten adhesive composition, and dispensing the molten adhesive composition onto a substrate. The liquid adhesive composition may be comprised of a polymeric reinforcing phase component and an adsorbent phase component, both as heterogeneously dispersed particulates in an adsorbed liquid component. The reinforcing phase component is substantially incompatible with the liquid component, the adsorbent phase component is compatible or substantially more compatible with the liquid component than is the reinforcing phase component, and the reinforcing phase and adsorbent phase components are partially compatible with one another. Hot-melt or other liquid compositions may also include nanoparticles at least partially exfoliated as a result of shear mixing.

A wall-mounted docking station for a portable computer connects the portable computer to a media entertainment system. The media entertainment system can have multiple zones throughout a room and/or a building, and can play audio, video, images, or other media stored on the portable computer to any zone or a combination of zones. Preferably, the docking station also provides power to the portable computer, and could optionally provide both power and data connectivity over a power line.

A rack with a rack body and a releasable locking portion holds two or more drinking vessels. The rack body includes a first and second locating devices, and a capture device to releasably capture the releasable locking portion. The releasable locking portion includes a first engagement device to engage with the capture device, and a second engagement device to engage with a second sector of each vessel base such that each vessel is prevented from moving in two perpendicular directions as a consequence of interaction between the vessel base, the second engagement device, and the first locating device, and is prevented from moving in a third perpendicular direction as a consequence of interaction between the second locating device and the upstanding portion.
