Abstract: In the electrolytic production of aluminum by electrowinning or electrorefining processes, cell components such as cathode current feeders which in use are normally covered with molten aluminum are made of a composite material of aluminum or an aluminum alloy or intermetallic compound with an aluminum oxycompound, usually alumina, and possibly containing minor amounts of additives such as borides carbides, nitrides or oxides. The composite material, which remains mechanically stable and electrically conductive at 1000 DEG  C., may be prepared by hot pressing powders at 1000 DEG -1700 DEG  C. possibly after surface treating the alumina to improve wettability by molten Al. The components are optionally coated, e.g. with TiB2. The composite materials are also useful as non-current carrying components, including separator walls, weirs, packing elements and baffles.

Abstract: A method of operation of an air cleaner comprises the steps of: detecting a concentration of a given gas by a gas sensor when a command signal for turning off the gas sensor is present; storing the concentration; turning off the gas sensor; detecting the concentration of the given gas by the gas sensor when a command signal for turning on the gas sensor is present; determining a reference value by choosing either the stored concentration or the concentration detected after the gas sensor is turned on which is lower than the other, at an instant that a predetermined interval has passed after the gas sensor is turned on; and controlling a blower motor of the air cleaner in accordance with difference between the reference value and the concentration detected after the gas sensor is turned on.  In a second method, the concentration is stored in a nonvolatile memory just before the air cleaner is turned off.

Title: Digital signal processing device
Inventor: CHEN KEPING
IPC: G06T1/00
Filed: 1991-04-17
Granted: 1996-05-07
Abstract: A  device  for  digital  signal  processing  and particularly  suited  for  video  and  image  processing applications. The device includes a linear array of 1024 processing  elements  (PE's),  an  external  controller interface,  input/output ports,  and an external memory interface.  The input/output ports allow the device to interface to equipment such as digitizing cameras and video  display  monitors.  The  device  uses  a  single instruction multiple data topology (SIMD) and incorporates two modes of communication: horizontal and vertical. Shift registers provide horizontal, i.e. parallel, communication between the PE's in the linear array. The linear array of processing elements  provides  one PE  for each digital sample, e.g. a pixel, thereby allowing a sequence of data samples, e.g. a video line, to be processed in real-time. Each PE includes a bit-serial arithmetic logic unit, a cache  memory  and  an  external  memory  interface.  All communication within a PE is along a one-bit wide bus, i.e. vertical mode, using a single move instruction with variable source and destination addresses. The processing capability of the device is further enhanced by having a serial-parallel multiplier in each PE. For applications requiring more than 1024 PE's, two or more devices can be cascaded together. In another embodiment of the present invention,   dual-port   memories   provide   horizontal communication between the PE's in the linear array.
