Abstract: An intermediary server allows endpoints connected to two different types of conferencing systems to participate in an integrated conference without requiring plugins to be installed at each endpoint. A conference identifier provided by a first type of conferencing system can be used by endpoints of a second type of conferencing system by allowing the intermediary server to send the conference identifier to a server of the first type of conferencing system and receive a link that a server of the second type of conferencing system can use to connect to the first type of conferencing system.

Abstract: A syringe has a barrel to receive a cartridge. The barrel has a front end portion to which a needle is connected for engagement with the cartridge. At its rear end, the barrel has a plunger mechanism. A sleeve is slidably mounted on the barrel and can be pushed forwards to sheath the needle. The needle is mounted on the barrel via a push-fit mounting device. The needle can be removed for disposal in a container by inserting the syringe into a tube on top of the container so that the protective needle sleeve is pushed back and the needle and mounting device pass through a collar of gripping fingers at an inner end of the tube. The fingers catch behind the mounting device so that this is pulled off to drop into the container with the needle when the syringe is withdrawn from the tube.
