Patent CA-2039640-A1 (CA)
Inventor: VASSILIADIS STAMATIS
IPC: G06F9/38
Filed: 1991-04-03
Abstract: Scalable compound instruction set machine and method which provides for processing a set of instructions or program to be executed by a computer to determine statically which instructions may be combined into compound instructions which are executed in parallel by a scalar machine. Such processing looks for classes of instructions that can be executed in parallel without data-dependent or hardware-dependent interlocks. Without regard to their original sequence the individual instructions are combined with one or more other individual instructions to form a compound instruction which eliminates interlocks. Control information is appended to identify information relevant to the execution of the compound instructions. The result is a stream of scalar instructions compounded or grouped together before instruction decode time so that they are already flagged and identified for selective simultaneous parallel execution by execution units. The compounding does not change the object code results and existing programs realize performance improvements while maintaining compatibility with previously implemented systems for which the original set of instructions was provided.

Abstract: The invention relates to a method and apparatus for heat-strengthening glass sheets. A glass sheet heated close to a softening temperature is heat strength-ened by cooling it at a certain controlled cooling rate. The cooling is effected in a space between cooling panels (9) and the cooling panels are cooled by a gas jet which is applied to the surfaces of cooling panels (9) facing away from the glass sheet. A cooling space temperature measurement can be used for controlling the power of a cooling jet.

Title: Auxiliary shielding and focussing device for a telescope
Inventor: SMITH PAUL
IPC: G02B27/00
Filed: 1991-09-03
Abstract: ABSTRACT OF THE DISCLOSURE    An auxiliary shielding and focusing device for a tele-scope is shown. The device is in the form of a lens cap which can be removably mounted over the light receiving front end of a telescope. The device has a generally flat surface and having two substantially equal size circular openings formed along a diameter therein. These openings are spaced equally from the respective immediately adjacent side along such diameter.  The openings prevent the formation of stray light within the telescope and create a parallax effect for the image such that double images are formed when the telescope is out of focus, and the double images will merge into a single sharp image when it is in focus. The openings also inherently serve as a shielding means to reduce the size of the front lens opening of the telescope so as to reduce the brightness of a glaring image of high intensity as well as to increase the resolution of such image.

Title: Addition of colloidal sno2 in the production of subpigmentary tio2
Inventor: ELFENTHAL LOTHAR
IPC: C09C1/36
Filed: 1992-01-20
Abstract: ABSTRACT     A process produces fine particle titanium dioxide essentially transparent to visible light and essentially UV radiation absorbing.  During preparation of the titanium dioxide product, tin dioxide with a particle size of 1 to 10 nm, and preferably 1 to 4 nm, is added, in an amount of 0.5 to 10 weight percent with respect to TiO2.  The particle size of the titanium dioxide is specifically adjusted by the tin dioxide addition.  Acicular particles are rounded by heat-treatment between 300 and 800° C. and preferably between 400 and 600° C.  The particles can be post-treated to produce a coating of inorganic and/or organic substances.  The fine particle titanium dioxide can be prepared by the decomposition of sodium titanate with hydrochloric acid or by suitable hydrolysis of a tetravalent titanium compound which leads to rutile formation.  A currently preferred way of adding the tin dioxide is as a colloidal sol which is prepared by the reaction of tin tetrachloride with water at a maximum of 22° C.

Abstract: An in-line noise attenuation device for insertion into a gas induction system, such as the air induction system of an automotive vehicle internal combustion engine. The device comprises two plastic parts snap-fitted together. One part is an outer tube (16), and the other part, an insert (18) disposed within the first part.  The insert comprises a hollow ogival-shaped section (30) that is axially coextensive with a frusto-conically shaped section of the outer tube (16) to form an annular flow path of substantially constant cross section for the inducted air. The flow then passes through apertures (42) in the insert (18) to enter a venturi section. The flow continues through the venturi section and then exits the device. The venturi section (46, 48) serves to choke noise that propagates from the engine in the direction opposite the direction of airflow. The noise is reflected back to the engine by the hollow interior of the ogival-shaped section which is open toward the venturi section.

Abstract: GEMAT 8 (60-SD-577) ABSTRACT OF THE DISCLOSURE      Carbon  fluoride  solid  compositions  having  a low fluorine-to-carbon ratio are produced by chemical vapor deposition processes.  These carbon fluoride compositions have    improved    wettability    characteristics    over polytetrafluoroethylene.  These compositions can be used as films,  coatings on substrates, powders,  and stand-alone articles.  These carbon fluoride compositions are produced by energizing vapors comprised of compounds containing fluorine and carbon to cause them to degrade into fragments which are then condensed onto a substrate to form the carbon fluoride solids.  These vapors can be energized by a variety of techniques, including hot filament techniques. The  carbon  fluoride  solids  find  utility  as  films  in aircraft de-icing, cookware, appliances, surgical tooling, chemical processing, gaskets, seals, diaphragms, packings, valve seats, windings, mold release components, extruder coatings,  medical  prosthetics,  and  other  similar  non-wetting applications.

Abstract: A process and an apparatus for economically igniting microwave plasmas wherein no undesirable reaction products in the reaction chamber impair the quality of cladding produced thereby. The plasma is ignited on the gas outlet side of the reaction chamber by means of a high voltage that is applied at least for a short period of time.       High-frequency pulses or low-frequency high voltages with frequencies in the range from 10 to 100 kHz are utilized.      The high voltage is synchronized with the microwave pulses.      According to a further process, the microwave pulses are excessively increased for a short time at least at their beginning. Also periodic excessive increases of the microwave pulses are possible. A switchable high-voltage source is connected by way of a delay member and a current supply unit to the microwave device. The output of the switchable high-voltage source is applied to the gas discharge line of the reaction chamber.

Abstract: Abstract A golf swing training device (20) comprised of a grip (26), a foreshortened shaft (24) and a hollow head (28). The head (28) contains a power source (68) activated by a switch assembly (66) also located within the head (28), to illuminate a lamp  (74)  of the lamp assembly  (64),  also within the head (28).  The lamp (74) emits a beam of light (30) downward to the ground and forward of the club head. The light beam (30) permits the golfer (22) to trace the arc of light corresponding to the golfer's swing to impart a mental image to the golfer of the precise club head path.   A second embodiment of the device (120) also com-prises a second light source (140) removably contained in the club grip  (26)  and channel  (132)  of the club shaft (24)  to produce a concentrated beam of light (130) in a direction coincident the longitudinal axis of the club shaft  (24).   Either embodiment of the device  (20,  120) also comprises a linear guide strip (200) which is placed on the ground in front of the golfer (22) to establish the desired  club  head  path.    The  golfer  (22)  preferably follows the path of the club head light beam during a swing  and compares  the  light path to  the guide  strip (200),  while  also  examining  the  full  circle  of  light produced by the second light source (140) contained in the club grip (26) and shaft (24).
