Title: Process for the production of thick-walled shaped articles especially for packaging uses
Inventor: SCHNEIDER GERHARD
IPC: D21J7/00
Filed: 1991-01-23
Abstract: ABSTRACT     In the process described, the raw material, in particular recycled paper and/or waste cardboard, in the form of an aqueous suspension, is brought by a suction filter out of suspension and on to a perforated surface the shape of which corresponds to that of the packaging article.  In order to manufacture shaped articles of this kind with sufficiently thick walls by suction filtering, the process disclosed calls for the suction effect on the raw material in the suspension to be exerted in the suction filter through spaced holes in the suction surface and through a bed, consisting of one or more layers, located directly on the suction surface.  This bed, which transmits the suction effect, has mesh apertures which are smaller than the holes in the suction surface.

Title: Process for the production of mono-n-substituted tetraaza macrocycles
Inventor: PLATZEK JOHANNES
IPC: A61K31/395
Filed: 1992-12-04
Abstract: Process for the production of mono-N-substituted tetraazacyclododecane and tetraazacyclotetradecane derivatives of general formula I (see formula I) in which n is 2 or 3, and R is .beta.-carboxylalkyl or .beta.-carboxylate alkyl, .beta.-cyanide alkyl, .beta.-carboxamidoalkyl, .beta.-hydroxyalkyl, aminocarbonyl, aminothiocarbonyl, .beta.-sulfamoylalkyl radical or a second tetraazacyclododecane or tetraazacyclotetradecane molecule bound by a bis(p-hydroxy)-alkylene chain, and wherein carboxyl and hydroxy groups are present optionally in protected form. The process comprises reacting a compound of general formula II obtained from 1,4,7,10-tetraazacyclododecane or 1,4,8,11-tetraazacyclotetradecane (see formula II) with an .alpha.,.beta.-unsaturated ester, amide or nitrile, or an epoxide, isocyanate, isothiocyanate, aziridine or a bisepoxide, with or without solvent, at 0 to 220°C, within 1 to 48 hours, and optionally at a pressure up to 100 atm. The thus obtained reaction mixture, after cooling to -20°C to 80°C, is mixed with a mixture of water/organic solvent and stirred for 0.5 to 12 hours.      The thus formed (optionally to be isolated) intermediate products carrying a formyl group on a nitrogen atom are reacted by adding an inorganic base or an acid at 0 to 150°C, within 1 to 72, with stirring, optionally followed by subsequent removal of protecting groups, to obtain the end product of formula I, which can then be isolated preferably as the hydrochloride. The process provides improved yields of the product.

Title: Press with vertically movable upper and lower drive means
Inventor: HAYASHI TETSUJI
IPC: B21D28/02
Filed: 1992-12-16
Abstract: ABSTRACT      A turret punch press wherein the upper and lower turrets are rotated, and the upper die positioned in the processing position is struck by a piston rod (striker element) of a striker device mounted on the lower end of a ram when the ram is lowered by means of a crank shaft (mechanical vertically moving means).  The piston rod can be freely moved vertically by a hydraulic cylinder so that the amount of the stroke of the striker element with respect to the upper die is the sum of the amount of the stroke of the ram and the amount of the stroke of the piston rod in the hydraulic cylinder itself.          Accordingly, the upper die and the lower die come into contact and the processing occurs only when the ram and the piston rod are both at bottom dead center.

Patent CA-2088043-A1 (CA)
Title: Structural system using light weight metal members
Inventor: STRUTT JAMES W
IPC: E04B5/02
Filed: 1993-01-25
Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is a structural system comprising wall panels upon which floor and ceiling panels are supported. The various panels are composed of light-gauge metal structural studs and tracks.  The studs and tracks are mechanically connected using a clinching machine for joining metal studs and tracks ranging in thickness from 16 to 20 gauge.  The metal is preferably galvanized steel.  The panels, as well as roof trusses, can be made in a plant where the panels can be surfaced or clad with insulation and specified finishes.  The structural capacity of the panels is independent of any diaphram strength contributed by the cladding.          Field erection of the panels to form a building may be carried out without resort to cranes due to the light weight nature of the panels and using unskilled labour.  Field connections may be made using sheet metal screws or by clinching.  The on-site joining of one panel to another uses a mating of stud to track in a parallel configuration in which the stud is nested in the track along the joint between panels.  This provides a tight, structural continuity between panels.  The use of a clinching machine in the manufacture of the panels to provide a mechanical joint equivalent in strength to a welded joint eliminates the need for worker protection from toxic fumes generated by welding galvanized metal, requires less extensive quality control and eliminates spot painting of welds for rust protection.

The second spring (84) bi-ases the actuating member (78) to move to an idle position in which no material is discharged onto the impeller (42) and causes the actu-ating member (78) to return to this idle position after movement thereof.
Patent CA-2091081-A1 (CA)
Inventor: EDGAR ALBERT D
IPC: H04N1/00
Filed: 1993-03-05
Abstract: A system and method to compensate for effects of a recording  medium  such  as  film  on  image  data  retrieved therefrom.  Red,   green,   blue,   and  infrared  light  is sequentially  transmitted  through  film  having  an  image exposed therein to the system which captures corresponding images. The infrared image maps the location, boundaries and intensities  of  the  media  defects.  The  map  is  employed combinatorially with the other captured images resulting in an image from the film free of the effects of the film defects. In one embodiment the effects of the imperfections are divided out from the red,  green,  blue spectra in an operation  dividing  out  the  infrared  image  data  on a pixel-by-pixel basis. In an alternate embodiment wherein the imperfections substantially prevent transmission of IR light therethrough,   the  IR  image  map  of  the  defects  is nevertheless employed with an automated fill-in algorithm more effectively utilized due to the precision with which the defect boundaries are known.

Title: Wide dimming range gas discharge lamp drive system
Inventor: ANTLE WOODROW L
IPC: H05B41/392
Filed: 1991-11-19
Abstract: A stable output, widely dimmable light source (20) utilizing a gas discharge lamp (14) including an external igniter (12) which is utilized to provide lamp ignition at approximately the same time as an AC potential source (22) provides power to the lamp (14) cathodes. A high voltage pulse is applied to the external igniter (12) causing ionization of the lamp gases at the start of each time period during which the ballasted AC potential source (22) is applied to the lamp (14). Average light output level is controlled by a light output selector (36) which controls lamp on time and thus the average light output of the lamp (44). During operation lamp (14) is turned on several times per second, such as sixty-eight and the AC potential source (22) has a relatively high frequency, such as 45 kHz. When utilized for providing backlighting for a liquid crystal display, the average lamp light output can be controlled in response to ambient light to provide proper backlighting in conditions which vary from total darkness to bright sunlight. For LCD applications lamp (14) has a serpentine shape to provide increased and uniform backlighting.
