Abstract: An injection device is described having a housing that receives a syringe. The syringe is biased by a return spring from an extended position in which the needle extends from the housing through an exit aperture to a retracted position in which it does not. A drive spring acts via a drive to advance the syringe from its retracted position to its extended position and discharge its contents through the needle and a return spring, brought into play when the drive has reached a nominal return position, restores the syringe to its retracted position. A releasable locking mechanism retains the syringe in its retracted position. A sleeve projects from the exit aperture and can be depressed to release the locking mechanism. A trigger has a rest position, in which it engages the drive, retaining it in a position corresponding to the retracted position of the syringe, and a depressed position, in which it no longer causes the drive to be so retained. The sleeve normally locks the trigger in its rest position. However, depression of the sleeve into the exit aperture, allows the trigger to be depressed. Thereafter, the trigger is retained in its active position.

Title: Harrow tine angle adjustment
Inventor: PAYNE DAVID ALAN
IPC: A01B19/08
Filed: 2007-02-23
Granted: 2014-07-08
Abstract: A simplified spike tooth harrow includes an apertured bracket pivotally connected to the fore-and-aft connecting strap extending between the tine bars. The bracket adjustably supports a tine bar from the strap. A pin selectively secured in one of the apertures contacts the strap to set the working angle of the tines on the bar when the harrow is operated in the field. A chain or link connected to the bracket at a location offset from the bracket pivot suspends the harrow from an upper drawbar assembly which is movable vertically between field-working and transport positions. When the drawbar assembly is raised to the transport position so the harrow is out of ground contact, the bracket pivots so the pin is offset from the strap and can be easily and quickly removed from the aperture and reinserted in a different aperture to change the tine angle.

Abstract: Structure, and a related method, for sealing, from the outside, a leaking puncture wound in the wall of a liquid container. This structure includes a patch body having a perimetered cavity selectively securable via a self-torque-limiting bolt to the outside of such a container in a manner whereby the cavity overlies and faces the wound, with the cavity's perimeter surrounding the wound, and a patch pellet contained and confined in the cavity and formed, at least in part, of a reaction substance which, with the patch body secured to the container, reacts to contact with liquid leaking from the container at least by imbibing such liquid and swelling to apply wound-sealing pressure, and more preferably by additionally reacting with leakage liquid to form a sticky coagulant mass for aiding in applying sealing pressure to the wound.  The patch body may either be placed directly against the outside of a container or may be employed with an intermediate, resilient gasket which centralizes the symmetrical introduction of leakage liquid into the pellet-containing cavity in the patch body.

Abstract: In one illustrative example, a mobile communication device operating in a wireless local area network (WLAN) of a communication network maintains an inter-enterprise voice call via its WLAN interface (e.g. 802.11/VoIP/SIP) with another communication device in the communication network. Communications of the voice call are maintained solely within the communication network and not routed through a conferencing gateway. During the voice call, a handover of the voice call from the WLAN to a wireless wide area network (WWAN) (e.g.  GSM/GPRS) may or may not be required. In response to identifying a handover indication during the voice call, the mobile device causes a request message (e.g. a SIP INVITE message) to be sent over the WWAN to the conferencing gateway for establishing a first connection leg through the WWAN via its WWAN  interface with a conference room of the conferencing gateway. The mobile device also causes a re-routing message (e.g. a SIP REFER message) to be sent over the WLAN to the communication device, so that a second connection leg between the communication device and the conference room of the conferencing gateway may be established. The first and the second connection legs are connected together in the conference room of the conferencing gateway for the voice call. Advantageously, inter-enterprise voice calls in the communication network need not unnecessarily and unduly burden the conferencing gateway, unless and until a handover of the voice call between the WLAN and the WWAN is required. Variations and other PSTN conferencing gateway techniques are also described.
