Filed: 1994-04-14
Abstract: Abstract of the Disclosure The present invention provides a process for producing hydrogen peroxide by reacting oxygen and hydro-gen in a reaction medium catalytically using, as a cata-lyst, a tin-modified platinum group metal supported on a carrier.  In the process using said catalyst, the pre-sence of halogen ion and acid in reaction medium is unnecessary unlike in conventional processes, and hydro-gen peroxide of high concentration can be produced effi-ciently.  Thus, the present process has no restriction for reactor material as seen in conventional processes and further allows for easy purification of produced hydrogen peroxide.

Patent CA-2126188-A1 (CA)
Inventor: NIEDER WOLFGANG
IPC: C21B5/02
Filed: 1993-10-19
Abstract: The invention concerns a method for continuously melting down scrap metal, in particular bales of scrap metal containing residual plastic materials, the scrap being fed to a melt-down reactor and the heat necessary to melt the scrap being provided by direct heating from underneath by burners located near the tapping point. Part of the gases produced are passed back, after utilizing the sensible heat and cleaning, as combustion gas into the melt-down reactor and the remainder passed out as output gas. A particular advantage of the invention is that, when melting down scrap metal containing plastic, it avoids the need for large-scale gas-purifying facilities and the pyrolysed materials contained in the starting material are utilized to good effect.

Patent CA-2137603-A1 (CA)
Inventor: FUJII SATOSHI
IPC: H05B3/14
Filed: 1994-12-08
Abstract: A boron-doped diamond resistance heater is provided herein. Such resistance heater includes at least one continual conductive line with ends, the lines and the ends being made of boron-doped single crystal diamond or polycrystal diamond. Insulating parts enclose the conductive lines, the insulating parts being made of non-doped diamond single crystal diamond or polycrystal diamond. Ohmic electrodes are formed on the ends of said conductive lines. When a voltage is applied between the electrodes, a current flows in the conductive lines, thereby generating Joule's heat, and the device acts as a heater. Since the whole device is made of diamond crystal, the heater can be of extremely small size. The heater has a high resistance against high temperature,especially in an anaerobic atmosphere. Moreover, such boron-doped diamond-resistance heater can be used in vacuum or in a liquid, since the insulating diamond layers are highly resistant against vacuum and liquids.

Abstract: Novel 1,2-dioxetanes with improved chemiluminescent properties, such as signal intensity, S/N ratio, T1/2, etc. are provided by spiroadamantyl 1,2-dioxetanes, wherein the remaining carbon atom of the ring bears an alkoxy, aryloxy, or arylalkoxy substituent, and either a phenyl or naphthyl ring, this aromatic ring bearing, at the meta position on the phenyl group, or a non-conjugated position on the naphthyl ring, an OX moiety wherein X is an enzyme-clevable group, which when removed from the dioxetane, leaves the oxyanion which decomposes with chemiluminescence, the aryl ring further bearing an electron-active substituent Z. The nature and placement of the Z substituent, at a position not adjacent the point of attachment to the dioxetane ring, strongly influences the properties of the dioxetane. Assays, as well as kits for the performance of those assays, include the dioxetane, an enzyme capable of cleaving the X group, and in certain cases, membranes and chemiluminescent enhancement agents.

It is even possible to arrange finishes on the boards before assembly. According to a preferred embodiment the gripping means are formed on at least a first edge of the wall board (5) by noses (12) arranged on the profile, wherein a groove for the profile extends partially between the nose and the wall board.
Patent CA-2143593-A1 (CA)
Inventor: KAMINOW IVAN P
IPC: H04B10/2581
Filed: 1995-02-28
Abstract: An optical frequency translator includes a frequency routing device formed on a semiconductive wafer between two reflective facets forming a laser cavity. Waveguides associated with the device each contain an integrated optical amplifier selectively acting as a gate preventing the flow of optical energy through a respective waveguide or as a gain-providing element which amplifies optical energy flowing through a respective waveguide. When a selective one of the optical amplifiers is activated with bias current the optical energy produced by this current operates in conjunction with the optical energy of the input signal so that lasing action occurs between the reflective facets. The lasing action occurs along a predetermined path determined by the optical amplifier or amplifiers that are activated. The lasing action in this particular path is supported at a particular selected frequency. This particularfrequency is the frequency to which the input signal is to be translated. An input waveguide is provided for injecting the input signal into the laser cavity. A separate output waveguide may be provided. Alternatively, the input and output signals may be transmitted on the same waveguide. A gain member such as a saturable absorber, for example, may be disposed in the laser cavity which optically couples the input waveguide to the frequency routing device.

IPC: H04N7/30
Filed: 1995-03-21
Abstract: A novel method and apparatus is disclosed for controlling inverse discrete cosine transform ("IDCT") mismatch between an encoder and decoder using different IDCT implementations under all coding conditions. Synchronization between the encoder and decoder is forced by selectively setting certain small DCT coefficients, which are prone to mismatch, to zero at the encoder. Advantageously, the invention may be implemented solely in the encoder to minimize system complexity and cost, and allow for IDCTmismatch control utilizing conventional decoders.

Title: Rotary hammer
Inventor: GIFFIN TIMOTHY H
IPC: E21B4/10
Filed: 1995-06-27
Abstract: Rotary impact hammers, which are primarily used for breaking up concrete, asphalt or frozen ground, include a rotating shaft with impacting members mounted thereon for repeatedly engaging a hammer to reciprocate the latter.  The present invention includes rollers mounted on pivot arms which are urged by centrifugal forces into engagement with the inner wall of a casing.   A reciprocating hammer is mounted on the casing with an anvil end extending into the casing for engagement by the rollers.  In order to reduce wear on the rollers and on the inner surface of the casing, the hammer is tilted into the direction of travel of the rollers, so that the rollers engage a ramp on the inner or top end of the hammer.  A reduced diameter area of the rollers engages the anvil end of the hammer, to reduce wear on the inner surface of the casing, particularly around the hole for the hammer.

Filed: 1995-01-06
Abstract: An apparatus for enveloping successive groups of items in a plastic film as the items traverse a linear path. Items are gathered in a group, and the group of items is then inserted in a tubular packaging film as the items and the film are conveyed at the same linear velocity. After the items are completely enveloped in the film, the film is severed and sealed to fully encapsulate them in the film. A vacuum is used to eliminate excess air generated within the tube, and also, in one form of the invention, form side gussets as sealing dies are closed. A tight package made at speeds results, with no need for any holes in the film to relieve internal air pressure.
