摘要:
A DNS server receives from a receiving email system, a DNS query for an email domain stored at the DNS server, the DNS query including identifying information of a sender of an email. The DNS server extracts the identifying information of the email sender from the DNS query and identifies one of a plurality of delivering organizations from the information. The DNS server determines whether the identified delivering organization is authorized to deliver email on behalf of the email domain. In response to determining that the identified delivering organization is authorized to deliver email on behalf of the email domain, the DNS server generates a target validation record based on the identity of the authorized delivering organization and the email domain, the target validation record including one or more rules indicating to the receiving email system whether the delivering organization is an authorized sender of email for the email domain.

A beverage container for a blender includes one or more vibrating mechanisms coupled to a bottom portion of the beverage container or integrated within one or more walls of the beverage container. After a beverage has been blended, the one or more vibrating mechanisms are activated as the beverage is being poured. Vibrations from the one or more vibrating mechanisms are mechanically transmitted to the beverage container, thereby promoting the pourability of the beverage from the beverage container, including dislodging ingredients in the beverage that became lodged or trapped in crevices of the beverage container during the prior blending process, and freeing up beverage ingredients that accumulated at the bottom of the beverage container during the prior blending process.

The invention relates to a breakaway link and a system for its use in conjunction with underwater gear, such as fishing nets, to prevent the prolonged entanglement and subsequent stress, harm to or death of cetaceans, including whales. The breakaway link system comprises underwater gear and at least one link which will rupture, break or experience calculated material failure upon receiving sufficient load induced by the force or struggling of the entangled cetacean. The breaking of the link frees the animal from the underwater gear, thereby reducing or eliminating the risk of severe stress, injury or death to the cetacean.
摘要:
A pneumatic gating mechanism which comprises a spool valve movable between two positions. In one position of the spool valve a supply line for gated items such as screws is connected to a delivery line and in the other position an air feed line is connected to the delivery line to blow said gated items therealong. A gate in said supply line is connected to the spool valve and opens and closes on movement of the spool valve. The gating mechanism may be combined with a pneumatically operable tool such as a screw driver and the pneumatic circuits of tool and gating mechanism linked so that items are gated only when the tool is not operating.

A replaceable head toothbrush construction 10 including an elongated handle member 20 having a hollow upper portion 24 provided with a contoured central bore 25 having an intermediate portion which defines a peripheral recess 28 and further including a head unit 12 which includes a plurality of head members 50. Each head member 50 comprises a different dental implement 60 such as a toothbrush element 61, a mirror element 62, a flossing element 63, etc. Each dental implement 60 is provided with a downwardly depending shaft 54 having a base segment 55 adapted to be captively engaged in the central bore 25 and the head members 50 and the handle member 20 is further provided with registration means 31, 53.
摘要:
An optical device is provided by a pigtailing method and comprises a substrate on which are integrated a layered optical waveguide component and optical fibre ends. The optical fibre ends are positioned in grooves). The method involves providing a substrate comprising grooves, notably V-shaped grooves, with a separately made optical waveguide component. The component is made on a separate flat substrate and released by virtue of a releasable layer present on the flat substrate. An advantageous releasable layer is made of a water-soluble salt. Flexible waveguide sheets such as can be used in the previously described method or, if provided with waveguide channels, as flexible waveguide components themselves are also disclosed.
