Title: Roller press
Inventor: ANDERSEN KNUD TONI
IPC: B02C4/32
Filed: 1994-04-07
Abstract: A roller press (1; 11) for grinding of granular material and comprising two or more rollers (3, 5; 13, 14, 15) alternately rotating in opposite directions, of which at least one is displaceable in a guideway (7; 16, 17) and where only some of the rollers (5; 14) are to a driving means. According to the invention the guideway for each of the displaceable rollers is provided so that it is substantially parallel to the resultant force on that roller. As a result, virtually all of the resultant force acting on the displaceable roller will be acting substantially in the direction of the guideway, thereby substantially eliminating the reaction force at right angles to the guideway.

Patent CA-2159156-A1 (CA)
Inventor: BECHERUCCI ANTONIO
IPC: G01N29/04
Filed: 1995-09-26
Abstract: An objective and non-destructive test of the fused joints in an armature, that can be used on every armature being manufactured on an armature manufacturing line, as well as apparatus for performing that test, are provided. The armature is immersed in an acoustic coupling medium. Acoustic pulses, preferably ultrasonic pulses, are beamed onto the commutator tang/wire interface region of a commutator tang/bar fused joint or the fused joint itself and an acoustic signature is measured. The quality of the joint can be determined by comparing the acoustic signature to a predetermined acoustic signature of known quality. A testing station on an armature production line includes a mechanism for removing the armature from the production line, immersing it in the coupling medium, and rotating it as each joint in the commutator of that armature is checked.

Patent CA-2176900-A1 (CA)
Title: Winch with reverse rotation protection
Inventor: BAZIUK MORRIS
IPC: B66D1/36
Filed: 1996-05-17
Abstract: A winch drum having a cable wrapped around a cylindrical surface of the drum and clamped to one end plate of the drum is modified by the addition of a member which inhibits reverse winding of the cable onto the drum. The member is attached to the clamped end of the cable and includes a tubular portion which is arcuate so as to follow the curvature of the cylindrical surface of the drum with a part cylindrical plate portion which projects outwardly to one side of the cable so as to lie flat against the cylindrical surface of the drum. When the cable is paid out to the maximum position, the member leaves the drum and impacts the frame of the winch to prevent or inhibit continued rotation of the drum in the payout direction which would otherwise cause winding of the cable in the reverse direction. The device for preventing reverse winding is particularly useful in winches which include a safety brake to restrict and control payout of the cable.

Title: Process for producing hydrogene and carbon oxides from dimethyl ether
Inventor: BHATTACHARYYA ALAKANANDA
IPC: C01B3/32
Filed: 1995-12-01
Abstract: A process for hydroshifting dimethyl ether is described which comprises passing a feed stream (36) which includes dimethyl ether and steam to a hydroshifting reaction zone (38) including an essentially alkali metal-free catalytic composition (40) substantially composed of copper or nickel in elemental form.  The process produces a hydroshifted product stream which is relatively rich in hydrogen, carbon monoxide, and carbon dioxide.  The feed stream can be transported relatively easily in liquid form at comparatively low pressures.  The hydroshifting reaction zone can include a hydrolysis reaction (38) zone and a water-gas shift reaction zone (58).  The hydrolyzed product and the water-gas shift product can be recovered to obtain hydrogen and carbon dioxide, respectively.  Additionally, the hydroshifted product stream can be blended with an oxidizing stream and combusted to drive a turbine (74) in order to generate mechanical energy.

Title: Process for recovering and recycling polyamide from carpet waste
Inventor: BOOIJ MARTIN
IPC: C08J11/08
Filed: 1996-08-21
Abstract: The present invention relates to a process for treating polyamide-containing carpet waste by extracting the polyamide from the carpet waste with an extraction agent containing an aliphatic alcohol. The separated polyamide can then be recovered from the extract and recycled for further use. In addition, carpet waste containing two types of polyamides can be treated in accordance with the present invention so as to separately recover each type of polyamide. The process according to the present invention provides a high yield of the polyamide. The presence of other constituents normally present in carpets does not interfere with the separating and recycling of the polyamide.

Inventor: SHWARTZ STEVEN P
IPC: G06F17/30
Filed: 1995-03-23
Abstract: A database query system includes a query assistant that permits the user to enter only queries that are both syntactically and semantically valid (and that can be processed by an SQL generator to produce semantically valid SQL). Through the use of dialog boxes, a user enters a query in an intermediate English-like language which is easily understood by the user. A query expert system monitors the query as it is being built, and using information about the structure of the database, it prevents the user from building semantically incorrect queries by disallowing choices in the dialog boxes which would create incorrect queries. An SQL generator is also provided which uses a set of transformations and pattern substitutions to convert the intermediate language into a syntactically and semantically correct SQL query. The intermediate language can represent complex SQL queries while at the same time being easy to understand. The intermediate language is also designed to be easily converted into SQL queries. In addition to the query assistant and the SQL generator, an administrative facility is provided which allows an administrator to add a conceptual layer to the underlying database making it easier for the user to query the database. This conceptual layer may contain alternate names for columns and tables, paths specifying standard and complex joins, definitions for virtual tables and columns, and limitations on user access.
