Inventor: DAVID CHARLES RICHARDS
IPC: B65B9/15
Filed: 1997-10-17
Granted: 1998-10-01
Abstract: Apparatus for packaging a series of potentially odorous objects respectively in individual packages distributed along an unbroken length of flexible substantially non-resilient tubing being withdrawn from a gathered back of such tubing to provide the walls of the packages, the apparatus comprising a guide cylinder open at an inlet end for the successive entry thereinto of the object to be packaged while the wall of the tubing passes over an entry rim at the end, the arrangement being such that manual pressure exerted through the rim as by the action of an object to be packaged when pressed into the guide cylinder causes the tubing to pass over the rim and along the guide cylinder while more tubing is drawn from the pack, the apparatus being further provided with clamping mechanism for engaging each package prior to passing the mechanism to hold it against rotation when the tubing is twisted between the package and the entry end completely to close the package by the actuation of twisting means provided for that purpose, and a flexible collection bag detachably mounted with its open end positioned to receive each package after passing the mechanism, the bag being arranged to be removed in a condition completely enclosing the packages contained therein and being made of material inhibiting any escape of odor due to osmotic action into the ambient atmosphere.

Filed: 1998-03-05
Granted: 1999-08-11
Abstract: The IC card of the present invention is capable of accessing loop-type buffers at high speed. Having the read directives for the following lines. When emitting a read directive from the read/write device, the first page of the buffering area to be read as specified by the command would be set in the PA register in the IC card. Then, based on the specific position of the page indicated by the PA register, such as the data of the first byte group, generates the address for reading in the memory of the IC card (EEPROM) for reading the data. When carrying out repeated reading of the increment of the PA register and reaching the last page of said buffering area, all the read data would be sent to the read/write device, which will, based on the reading directive on the line, read once the status data of all the page of the loop-type buffer and detecting the page written last, thus, to carry out read/write to the loop-type buffer.

Title: Apparatus for sensing wafer insertion state in a cassette for a handler
Inventor: AHN BYUNG-SEOL
IPC: B65G1/00
Filed: 1998-08-28
Granted: 2001-12-11
Abstract: An apparatus for sensing a wafer insertion state in a cassette for a handler optically detects a state of a wafer inserted into a cassette placed on a stage and vertically operated, and determines whether or not the wafer is wrongly inserted into the cassette slot by using the detected signal by way of timer. The apparatus includes: a light beam source and a photo-detector positioned to both symmetrical sides opposing around the cassette; decision means for determining a wafer insertion miss by using an output signal of the photo-detector when a shading by the wafer occurs over a predetermined time; and a driving means for performing an interlock operation when the wafer insertion miss is determined by the decision means. As a result, a wafer damage generated when the wafer is abnormally inserted into the slots of the cassette is prevented, thereby enhancing a production yield of the wafer and a reliability of a handler.

Title: Double spring precompression pump with priming feature
Inventor: SCHULTZ ROBERT S
IPC: B05B11/00
Filed: 1999-10-22
Granted: 2001-11-21
Abstract: The invention relates to a precompression pump which includes a feature for opening the outlet valve at the bottom of the pump stroke, to thereby evacuate air and liquid from the pump chamber. The pump includes a gravity-biased inlet valve and a spring-biased outlet valve. Elevated pressure in the pump chamber causes the outlet valve to open against the bias of the outlet valve spring. At least one of the outlet valve or the inlet valve has an engagement end which engages the other valve at the bottom of the pump stroke, to thereby open the outlet valve against the bias of the outlet valve spring and exhaust air and liquid from the pump chamber to the spray nozzle. In this way, the pump chamber is evacuated so that liquid can be drawn into the pump chamber from the bottle or container. The present invention uses a simple design which is easy to mold, does not require close tolerancing, and which operates effectively without the need for difficult-to-mold friction fits.

Title: Cluster node distress signal
Inventor: BLOCK TIMOTHY ROY
IPC: G06F11/30
Filed: 1999-12-23
Granted: 2001-12-01
Abstract: The preferred embodiment of the present invention provides a cluster node distress system and method that improves the reliability of a cluster. The cluster node distress system provides a cluster node distress signal when a node on the cluster is about to fail. This allows the cluster to better to determine whether a non-communicating node has failed or has merely been partitioned from the cluster. The preferred cluster node distress system is embedded deeply into the operating system and provides a pre-built node distress signal that can be quickly sent to other nodes in the cluster when an imminent failure of that node is detected, improving the probability that the node distress signal will get out before the node totally fails. When the node distress signal is effectively sent to other nodes in the cluster, the cluster can accurately determine that the node has failed and has not just partitioned from the cluster. This allows the cluster to respond correctly, i.e., by assigning other nodes primary responsibility, with less intervention needed by administrators.
