Title: Method and apparatus for dispensing small amounts of liquid material
Inventor: SAIDMAN LAURENCE B
IPC: G01F13/00
Filed: 1999-04-30
Abstract: Apparatus and methods for dispensing droplets of liquid or viscous material. The apparatus generally comprises a valve operated dispenser (10) and a control (128', 129) for moving the valve member (42') with respect to a valve seat (38') in rapid succession. This rapidly accelerates liquid or viscous material in a stream from the dispenser outlet and immediately breaks the stream into a minute droplet. Various embodiments of the valve seat (38') include both rigid valve seats and resilient valve seats. Resilient valve seats are especially useful for dispensing solder pastes as they can prevent material flaking, compacting and clogging conditions. Low friction polymer or plastic material for dispenser components such as the valve member (42') and outlet structure (40') can also prevent such problems.

Title: Optical readable disc storing full-motion video scene
Inventor: DE HAAN WIEBE
IPC: H04N7/24
Filed: 1991-05-31
Abstract: A compact disc-like display device is adapted to display a sequence of pictures which jointly represent a full-motion video scene, which picture sequence is digitized by means of some suitably chosen encoding algorithm. The digitized picture sequence comprises a series of video blocks. Since the disc continues to rotate at the normal speed when the picture sequence is displayed in slow motion, or in the case of a freeze, discontinuities in the display of the picture sequence are produced. To inhibit this, a header referring to a predetermined video block, preferably the next block, is associated with each video block so that the display device has information about that picture which is to be displayed next. The display device searches, reads and processes the associated video block on the disc.

Abstract: A method and apparatus for releasing remaining subscriber activities through the use of a service termination command. A home public land mobile network (HPLMN) is informed of remaining activities by visited PLMNs (VPLMN) and interrogating PLMNs (IPLMN).  The HPLMN sends a timer to the VPLMNs and IPLMNs in a MAP operation. If upon expiration of the timer the subscriber has remaining activities in the node, then the node sends an alert to the HPLMN. The timer may be based upon a fraud risk of the PLMN and/or of the fraud risk of the subscriber. Accordingly, the HPLMN waits for an alert from a particular node before sending a service termination to the node.
