Title: Device for sidewise shifting of a tool in a slotting station contained within a machine processing plate-like workpieces
Inventor: CAPDEBOSCQ BERNARD
IPC: B31B50/22
Filed: 1990-02-23
Granted: 1994-06-14
Abstract: The invention provides a device for sidewise shifting and positioning of a tool in a slotting station situated within a machine used for processing plate-like workpieces. This station includes creasing tools (60) and associated counter-parts (75) mounted to a first pair of vertically spaced and horizontally parallel shafts (40, 50), slotting tools and associated counterparts, fitted on another pair of shafts arranged downstream, and a master plate held vertically in the shifting direction of the workpieces by two transverse shafts: a guiding shaft (30) and a threaded shaft (10), the latter being capable of imparting a lateral shift to the master plate (100). The master plate (100) has on its periphery appropriate means (106, 107) for the lateral guiding of the respective tools. A system for the lateral guiding of a tool to be shifted in response to the shifting of other tools is provided on a secondary plate (225) fitted on the master plate (100) by a mechanical arrangement (130, 205, 208) allowing the secondary plate (225) to be moved in a translational motion orthogonal to the master plate (100), while being held simultaneously fully parallel to the master plate.

Patent CA-2025184-C (CA)
Inventor: FULTON STEVEN J
IPC: B05C11/02
Filed: 1990-09-12
Granted: 1996-05-21
Abstract: In the embodiment described in the specification, a hot melt ink image on a substrate (11) is treated in a continuous manner by moving it along a platen (27) having a heating zone to melt drops (38) of hot melt ink and cause them to spread on the substrate.  The platen has a flat central portion (34) and curved portions (33,35) at each end with curvatures suffi-cient to prevent formation of cockle.  At the output end of the heating zone, the substrate (11) is moved continuously into a quenching zone (36) where a cool-ing platen (16) cools the substrate (11) by thermal contact at a rapid rate to prevent crystallization or frosting of the hot melt ink image.  After the quench-ing zone, the substrate is moved along a surface hav-ing a reverse curvature with respect to the curved portions (33, 35) of the heating platen (27) to elim-inate residual curvature of the substrate resulting from the curved portions of the heating platen.

Granted: 2000-07-04
Abstract: A method and apparatus of scrubbing acid gas from flue gas comprises slats which define a moving bed of scrubbing material which is capable of reacting with the acid gas to form reaction products on particles of the scrubbing material. Flue gas from a boiler or other sources of flue gas is passed through the moving bed of scrubbing material.

Title: Process for making wood composite employing blast-furnace slag as the binder and the wood composite product so produced
Inventor: HSU WU-HSIUNG E
IPC: C04B18/26
Filed: 1991-09-04
Granted: 1996-12-10
Abstract: A novel method of making a wood composite employing cellulosic material as the wood component and pulverized blast-furnace slag as the binder component and the product produced thereby is disclosed.  A settable mixture of the wood component, binder component and water is prepared and thereafter  subjected  to  a  forming  pressure  within  a confined space.   While in its confined condition,  the mixture is also subjected to heat and carbon dioxide (CO2) for  a  time  and  at  a  temperature  sufficient  to  cause accelerated and early setting of the mixture.  Optionally, calcium-rich compounds can be added to the settable mixture as a slag cement binder enhancer and sodium silicate can also be used as a mineralizer.  The cellulosic material can also be pre-treated with a fire retardant resulting in a cementatious  wood  composite  exhibiting  improved  fire resistance and in situ fire load bearing strength.  Slag cement is plentiful, being a by-product of steel mills, but as a binder, is significantly less expensive than Portland cement.  Employing CO2 injection, comparable set times for slag and Portland cements can be obtained, but the wood composite employing a slag cement binder has superior final strength.

IPC: H04B1/16
Filed: 1992-04-30
Granted: 1997-03-25
Abstract: Multiple simultaneous uses of a multi-service digital receiver are made possible with a single practical analog-to-digital converter (38) by translating the various ser-vice bands in frequency to form a single, generally contin-uous composite service band in which substantial frequency gaps  (6) between the different services are eliminated. Bandwidth requirements are further reduced by a bandfolding technique in which at least one service waveband is divided about an intermediate mixing frequency (Fmix), the divided portions are overlapped so that they collectively occupy a sub-waveband with a smaller bandwidth than the original band, and the mixing frequency (Fmix) is chosen such that user-selected frequencies do not interfere with other ac-tive frequencies.  Interference between non-selected active frequencies is permissible and simply ignored.

Abstract: A combination muffler and catalytic converter for an exhaust system of a small internal combustion engine. The catalytic converter is mounted within a chamber formed inside the muffler which functions not only to contain the catalytic converter but also to provide sound attenuation.  The combination muffler/catalytic converter also includes an assembly for introducing secondary air into the interior of the muffler body containing the catalytic converter so that harmful uncombusted components such as hydrocarbons, carbon monoxide and nitrous oxides contained in the exhaust gases are further combusted prior to exiting the muffler.  The secondary air supply assembly includes an opening formed in the muffler body which communicates between the interior of the muffler body and atmosphere, and a reed valve mounted directly on the muffler body adjacent this opening.  The reed valve is operable in response to exhaust gas pressure pulsations within the muffler between a  normally closed position which seals the opening and an open position which unseals the opening to permit atmospheric air to flow into the interior of the muffler body.
