Title: An inorganic separator stack to micro-pattern organic layers
Inventor: PY CHRISTOPHE
IPC: H01L27/32
Filed: 1999-11-30
Abstract: A patterned layer of organic material is formed on a substrate by depositing a composite stack of at least two inorganic layers on the substrate. The inorganic layers have different etch rates, with the upper layer having a lower etch rate than the underlying layer. The composite stack is masked to leave exposed portions defining a pattern. The exposed portions are then etched away to form a separator with an overhang resulting from the different etch rates of the layers. An organic layer is deposited on the resulting structure using a directional deposition technique to form a patterned organic layer.

Patent CA-2312066-A1 (CA)
Title: Apparatus for controlling delivery of fluid material
Inventor: GUNTON BRUCE STANLEY
IPC: G08C17/02
Filed: 2000-06-20
Abstract: Apparatus is described for controlling delivery of dangerous material, such as LPG, from a tanker 12 to a tank 14, through a pipe 16. A valve 18 is controlled by an arrangement 22. An operator 28 carries a radio transmitter 24 and must periodically transmit an appropriate signal to the control 22, otherwise the control 22 will time out and close the valve, also sounding an alarm. In accordance with the invention, the transmitter 24 is also provided with a timer, having a shorter count down time, and also re-set when the signal is sent to the control 22. The timer in the transmitter 24 alerts the operator that a signal should be sent, giving the operator an opportunity to send a signal before the control 22 closes the valve 18. However, if the operator does not send a signal, or is incapable of doing so, the timer at 22 will assume that an emergency situation exists, and cease further delivery.

Filed: 2000-07-06
Abstract: Initially, a client requests a specific document and provides the preferences, including readability level preferences of the document, locale preferences, content filtering instructions preferences, governmental regulations preferences, natural language preferences, and document syntactic format preferences. The transcoding proxy requests and receives the document from the origin server, with the document having origin semantic characteristics.  The document from the origin server has an origin readability level and origin locale, is conformant with origin content filtering instructions and origin governmental regulations, and is in origin natural language and in origin document syntactic format. Using the client semantics preferences, the transcoding proxy revises the document in a sequential or parallel fashion.  The origin semantics characteristics of the document are, thus, revised to the semantic preferences specified by the client.
