Patent CA-1271896-A (CA)

Abstract: Abstract The invention relates to a continuous process for the manufacture of butyl rubber in which the monomers are polymerised using a halogenated polymerisation medium in a self-cleaning screw extruder at a constant pressure under boiling plug-flow conditions by means of a modified aluminium halide catalyst which operates at high temperature (relative to prior art very low temperatures of e.g. -100°C).   In contrast to prior art slurry processes ,the polymerisation mixture forms a sticky, highly viscous mass which is conveyed by screw action to the extruder outlet as polymerisation proceeds.   The butyl rubber product is separated at a high concentration from vapours of unreacted monomers and polymerisation medium which are recycled.   Cooling is effected by vapourisation of a portion of the mixture of monomers and polymerisation medium in a flash tank before supply to the extruder and returning the vapourised fraction and recycle vapours to the flash tank through, in succession, a compressor, heat exchanger and throttle valve.     By using the process of the invention, the total energy consumption in butyl rubber manufacture can be cut to about 20% of that of prior art processes.

Abstract: MULTIPLEXED REAL-TIME PYRAMID SIGNAL PROCESSING SYSTEM         Abstract of the Disclosure An improved apparatus, for use in a Burt Pyramid or filter-subtract-decimate type analyzer or synthesizer (Fig. 3), reduces the amount of hardware needed to carry out its function.  The apparatus operates with a given sampled, temporal signal (Go or L'O...G'M) such as a video signal, representing an n-dimensional information component.  The improved apparatus comprises a multiplexed (synthesizer or analyzer) stage (303x or 328x) to respond, in accordance with each of repetitively generated sets of time synchronized serially-occurring control signals, to a serial stream of samples of a predetermined number of subspectra (GO...Gm) of the given signal, the samples being arranged in a predetermined temporal order format with respect to each other.

Abstract: ABSTRACT OF THE DISCLOSURE   In an internal combustion engine with overhead valve and overhead cam type valve gear, a self-pumping hydraulic-type lash adjuster located downward from the lubricated camshaft and supplied by oil run-off from the camshaft and associated rocker arm member. The lash adjuster includes a housing with a cylindrical aperture therein in which a first plunger member is tightly slidably fitted for reciprocation forming a power chamber with the lower end of the housing. A second plunger member is relativelyloosely fitted in the aperture of the housing and has a portion extending from the upper end of the housing for receiving force inputs from the rotating camshaft and associated rocker arm member. A reservoir chamber is formed by the first and second plungermembers and is communicated by one-way check valve means to the power chamber topermit flow from the reservoir to the power chamber, but not otherwise. As the lobes of the camshaft produce pivotal or rocking movement of the rocker arm member, the second plunger member which supports one end of the rocker arm member is alternately cocked in a side-by-side lateral movement within the housing which movement tends to pump oil collected at the upper end of the lash adjuster housing into the reservoir chamber without the need of providing for a pressurized oil feed or passage in the engine cylinder head.

Abstract: METHOD AND SYSTEM FOR HIGH-SPEED, 3-D IMAGING OF AN OBJECT AT A VISION STATION                    ABSTRACT         A method and system for high-speed, 3-imaging of an object at a vision station including a  flying  spot  laser  scanner,   a  dynamically configurable  spatial  filter  and  a  diffuser  for spatial averaging, are used in conjunction with a variable transmission filter in an optical depth sensing   system.    The  reflected  laser  signal received by the sensing system is first spatially filtered and averaged and then split into first and second beams which are imaged onto a pair of highly sensitive photodetectors which introduce capability for high-speed, 3-D sensing under low light level conditions.   The  first  beam  passes  through  a variable  transmission  filter  which  is  used  to encode position which, in turn, is proportional to the height of the object.  The second or reference split beam is provided to compensate for changes in the reflectance of the object and the power of the laser scanner.  A high-speed signal processing unit which  incorporates  special  circuitry  to  greatly extend  dynamic  range  computes  the  ratio of  the transmitted  signal  to  the  sum  of  the  reference signal  and  the  transmitted  signal  to  determine height  information.   The  signal  processing  unit also contains noise rejection circuitry which is activated during "off" and "on" periods of laser diode TTL modulation and includes feedback control for pulse amplitude modulation of the laser diode source if necessary to increase dynamic range of the system,

Abstract: The method of monitoring a hidden coal-rock inter-face includes irradiating the medium being monitoring from a gamma-ray source and registering by a detector the int-ensity of backward scattered radiation at a spacing from the surface of the monitoring medium and at a spacing from the radiation source. There are formed at the detector two zones of reception or backward scattered radiation, diff-erently spaced from the source, so that the intensity of backward scattered radiation received by the zone closer to the source diminishes, and the intensity of backward scattered radiation received  by the zone more remote from the source grows with a growing spacing of the de-tector from the monitored medium.  The intensities of backward scattered radiation at the two zones are summed up to obtain the summary intensity invariant with respect to a varying spacing of the detector from the monitored medium.  The transmitter for performing the method comp-rises a housing acommodating a gamma-ray source and a de-tector of backward scattered radiation, enclosed in a screen having made therein ports differently spaced from the source. The area of the port more remote from the source is greater than the area of the less remote port, and the spacing of the source from the detector does not exceed a preset maximum value of the spacing of the detec-tor from the monitoring medium.
