Title: Coated articles and method for the prevention of fuel thermal degradation deposits
Inventor: COFFINBERRY GEORGE A
IPC: C10L3/00
Filed: 1994-01-13
Abstract: Articles for hot hydrocarbon fluid wherein the surface for contacting the fluid is a metal oxide, amorphous glass or metal fluoride diffusion barrier material coated on a metal substrate. The metal oxide, amorphous glass or metal fluoride is deposited by chemical vapor deposition (CVD), e.g., by effusive CVD of an organometallic compound on the surface without the use of carrier gas, without pre-oxidation of the surface and without thermal decomposition of the diffusion barrier coating material. Examples of coating materials deposited by effusive CVD are SiO2, TiO2, spinal and Al2O3. The articles having the coated surfaces find utility in components subjected to high temperatures wherein the components are in contact with hydrocarbon fluids without additives, without special attention to quality control and without the need for special processing.

Title: Real-time convolutional decoder with block synchronizing function
Inventor: ABE MASAMI
IPC: H03M13/23
Filed: 1994-06-21
Abstract: ABSTRACT      A decoder receives frames of data that have been block coded, then convolutional coded, at a rate of multiple frames per block.  As each frame is received, the decoder counts it, stores convolutional code path information, and updates metric values pertaining to the paths.  Once per block of frames, the decoder selects a path having the best metric value, convolutionally decodes one block, detects errors from both the block code and path metric, and generates error information.  From the error information, the decoder decides whether block synchronization has been acquired or lost, and clears, decrements, or sets the frame count accordingly.  If synchronized, the decoder outputs the block and its error information, and updates the path memory in preparation to decode the next block.  Otherwise, the decoder prepares to reacquire block synchronization.

Patent CA-2128566-A1 (CA)
Inventor: WACKER PAUL C
IPC: G05D22/02
Filed: 1994-07-21
Abstract: A humidity control system for a space receiving conditioned air from a duct has sensors which measure the current humidity in both the space and the duct. The system calculates a duct set point based on the difference between the current space humidity and the humidity set point for the space. The system then controls the humidity of the air passing through the duct so as to both minimize the difference between the space humidity and the humidity set point for the space and to prevent the air in the duct from reaching its dew point. A special algorithm is used to compensate for lag in the duct's humidity sensor.

Filed: 1993-04-02
Abstract: The invention describes a feed device that feeds assembly parts such as nuts, bolts, and rivets, from a sorting unit to the feed channel of a processing device for pressing or mounting of assembly parts to sheet metal.  The feed device consists of a nozzle with a nozzle channel through it connected on one end to a feed line coming from the sorting unit.  A protrusion of the nozzle can deploy into a recess opening of a guide piece of the processing device so that the nozzle channel will open laterally into the feed channel of the device.  To connect the nozzle to the guide piece, two levers linked to the nozzle are used; they are pretensioned by springs in a closed position surrounding the guide piece and can be moved manually, possibly with the assistance of a tool, into an open position.  In this  manner the feed device can be easily connected to the processing device and then detached from it (Figure 1).
