The injection device includes a housing having a receptacle for an injection fluid vessel and an operator-manipulated element configured to be rotatable to set an amount of injection fluid to be dispensed. The operator-manipulated element is further configured to move relative to the housing in the direction of the center axis in the distal direction when rotated. The operator-manipulated element further is displaceable in the proximal direction to dispense injection fluid. A feed part is connected to the operator-manipulated element in a rotatably fixed manner and is displaced in the direction of the center axis in the distal direction during the setting of the amount of injection fluid to be dispensed. The feed part is connected to the housing in a rotatably fixed manner and is displaced in the direction of the center axis in the distal direction when the injection fluid is dispensed. A blocking contour extends around the center axis in a spiral-like manner and coacts with the feed part and to block a movement of the feed part in the direction of the center axis in the proximal direction. The blocking contour has at least at one location an interruption configured to allow a movement of the feed part in the direction of the center axis in the proximal direction. | 11-27-2014 |

20130124685 | DISTRIBUTING OVERLAY NETWORK INGRESS INFORMATION - Aspects of the present disclosure relate to providing secure access to resources of a private network. For example, a client device may transmit a request identifying the protected resource to an authentication server. The authentication server queries a network address lookup table to identify a network address of the protected resource based on the identifying information of the request. If the network address denotes a network location that is not generally accessible, the authentication server generates a resource record that identifies a bastion host, a port, and a connection method for accessing the protected resource. The resource record and the network address may then be transmitted to the client device. In response, the client device may use the information in the resource record to establish a tunnel connection with the bastion host, and the client device uses the tunnel connection to access the protected resource via the bastion host. | 05-16-2013 |
