Abstract: Optical element (100), for a lamp or lighting apparatus having one light-emitting diode (LED) as a light source, that distributes unidirectional light output from the LED into an omnidirectional output with a controlled variance in light intensity. A diffuser can also be used around the optical element and the LED to provide further distribution of the light rays by e.g. scattering. The optical element (100) is positioned adjacent to said LED and defines a central axis (CA) and a lateral axis (L) that is substantially orthogonal to the central axis (CA), said optical element (100) extending circumferentially about the central axis (CA) and comprising a convex light-receiving surface (102) that is symmetrical about the central axis (CA) and positioned adjacent to said LED, a frusto-conical light-projecting surface (104) positioned laterally outside the convex light-receiving surface (102) and substantially symmetrical about the central axis (CA) and an curved light-reflecting surface (114) positioned laterally inside the frusto-conical light- projecting surface (104) and substantially symmetrical about the central axis (CA), the curved light-reflecting surface (114) being spaced apart along the central axis (CA) from the convex light- receiving surface (102).

Title: Method of recovering steel reinforcement from conveyor belts
Inventor: HAMILTON JOHN S
IPC: B29B17/02
Filed: 2015-02-11
Abstract: The present invention is based upon the discovery that the level of adhesion between steel reinforcing elements and rubber products, such as conveyor belts, in which they are embedded can be significantly reduced by heating the steel reinforcing elements by induction heating to break down the level of bonding between the steel reinforcing elements and the rubber in the article. The present invention more specifically discloses a method for recovering steel reinforcements from a conveyor belt carcass having steel reinforcements which are bonded to the carcass of the conveyor belt, said method comprising (1) heating the steel reinforcements in the conveyor belt by induction heating to a temperature which is sufficient to substantially breakdown bonding between the steel reinforcements and the carcass of the conveyor belt and (2) applying a mechanical force to the steel reinforcements which is sufficient to separate the steel reinforcements from the conveyor belt carcass.

Abstract: A method of manipulating thermoplastic film to create integrated features and particularly relates to an improved method of manufacturing a packaging bag that is reclosable after initial opening. Multiple sections of thermoplastic film are layered on top of themselves to form a multi-layer portion of the thermoplastic film. The multi-layer portion may then be conglomerated into a unitary thicker portion of the film that can then be shaped into a closure strip. In order to form a bag, a second such closure strip may be made. The two closure strips are then aligned and the remaining open portions of the bag are then sealed such that the closure strips form a reclosable opening that may be opened and closed repeatedly.

Abstract: The present invention extends to methods, systems, and computer program products for reliable messaging using clocks with synchronized rates. Embodiments of the present invention insure at-most-once delivery of messages. A source and a destination utilize clocks with synchronized rates. Messages are assigned Time-To-Live ("TTL") values such that state information is updated the source and removed at the destination when a corresponding message timer based on a TTL value expires. Accordingly, resources consumed to maintain state information at the destination can be freed up in a shorter period of time. The source can retransmit state information to the message destination if relevant state information has been removed. Message processor instance IDs insure at-most-once delivery when a message destination suffers an involuntary memory loss.  Embodiments of the present invention can also be used for exactly-once-delivery, for example, when TTL  values are infinite and instance IDs are not used.
