Patent CA-2037527-A1 (CA)
Inventor: OKUYAMA HIDEKI
IPC: H04L1/00
Filed: 1991-03-04
Abstract: In an error correcting system for use in transmitting a packet from a transmitter to a receiver a packet header is preceded by an input signal and is formed by a Reed-Solomon code in the transmitter by adding an error correcting code to a header information signal.  In the receiver, a plurality of syndromes are calculated by a syndrome calculator in response to the packet header to detect whether or not at least one error is included in the packet header.  On detection of at least one error, an error correction circuit is energized in accordance with a program to locate and to correct the at least one error on the basis of procedure determined for correction of the Reed-Solomon code and may be structured by a plurality of hardware circuits.

Title: Circuit board for surge absorber for communication lines
Inventor: ITO TAKAAKI
IPC: H04B3/00
Filed: 1990-11-27
Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus is disclosed wherein, when a group of surge absorbing elements for use with an apparatus to be connected to communication lines are disposed onto a circuit board for a surge absorber, a predetermined holding circuit board separate from the circuit board for a surge absorber is employed to reduce the mounting area of the group of surge absorbing elements and improve the dielectric strength of the holding circuit board, and it is possible to reduce the mounting area of the group of surge absorbing elements on the cirucit board for a surge absorber to about one half or below  one  half  that  of  a  conventional  apparatus. Further,  since  the  distances  between  individual  wiring patterns can be reduced if the dielectric strength of the holding circuit board is equal, the area of the holding circuit board can be further decreased.

Title: Sheet set separation using wide folded strips
Inventor: LUPERTI HARRY E
IPC: B65C1/04
Filed: 1991-12-23
Abstract: ABSTRACT OF THE DISCLOSURE       Apparatus and a method are disclosed for associating a relatively wide strip with a set of stacked sheets.  The strip, which may be a paper tape, is positioned to intersect a path along which a set of sheets such as paper sheets is advanced.          The sheet set is advanced towards the strip and a nip is formed by a pair of opposed belt conveyers so that the downstream edge of the sheet set engages the strip and carries the strip into the nip of the belt conveyers where the strip is folded at least once to the  sheet set adjacent the downstream edge of the sheet set. The strip is indexed from a roll to the position in the path of the sheet set. The strip is tensioned and is drawn against a knife edge as the sheet set advances through the nip to sever the strip from the roll.  Pairs of opposed rollers, each pair forming another nip, are disposed adjacent the nip formed by the belt conveyers to cooperate with that nip and form a wider composite nip for folding wider strips and skewed narrower strips.

Title: Method and arrangement for purging molten metal in a container with the aid of a gas
Inventor: FALK THOMAS
IPC: F27D3/16
Filed: 1992-02-16
Abstract: A B S T R A C T In the purging and agitation of molten metal carried in a ladle by injecting a pressurized gas into the molten metal through the intermediary of a nozzle mounted on the wall or on the bottom of the container, there is proposed a method for clearing the nozzle of blockages that are caused by molten metal being drawn into the nozzle-throughflow passage immediately the flow of pressurized gas is cut-off, and freezing on the walls of the nozzle to form a blockage. The inventive method is characterized by passing an electric current through at least part of the nozzle at the same as the supply of pressurized gas is switched on, such as to heat and therewith at least partially melt the metal blockage in the throughflow passage of the nozzle, this at least partially melted metal blockage being forced from the passage by the pressurized gas flowing therethrough.

Title: Round robbie
Inventor: MULHOLLAND ADRIAN
IPC: B25B15/00
Filed: 1992-06-18
Abstract: ABSTRACT OF THE DISCLOSURE    This article of manufacture, hereafter referred to as "Round Robbie",  is a torque application device which is comprised of a shaft and  a  head.  The said screwdriver head  is  of  a generally globular or spherical shape having four equal planar sides, with the diameter equal throughout allowing for the insertion or removal of any appropriate fasteners using a square socket type head. The distal end of the head has four equal sides, each of which has an upper slightly inwardly inclined flat portion which merges without discontinuity  at  its  lower  end.  The  proximal  portion  of  the spherical head narrows in similar fashion to a narrowed neck that is in diameter, typically from half to three quarters the diameter of the shaft. These four sides being generally equidistant, brings the said head into engagement with the side boundary of the said cavity of  the  body  of  any said fastener.  The  turning  of  said screwdriver causes the application of  torque directly from said device head to said fastener allowing for the insertion or removal of  appropriate  fasteners  at  an  oblique  angle,  transmitting the torque to the screw even when the screwdriver axis and the screw axis are not co-linear.    The purpose of the forgoing abstract is to enable the Patent Office  and  the  Public  generally  to  determine  from  a   cursory inspection the  nature  of  the  technical  disclosure  of  the application.  The  abstract  is  neither  intended  to  define  the application of the invention, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.

Abstract: In a process for folding dough sheets, in particular strudel dough sheets, at least one dough sheet is folded inward in opposite directions in at least two consecutive folding operations along parallel fold lines, and the exposed edges of the dough sheet that are parallel to the fold line come to lie within the projection of the folded dough sheet, after which the dough sheet folded this way is tucked on a first end along a line running crosswise to the parallel fold lines.  Starting from the folded dough sheet's other end that is opposite in the direction of the parallel fold lines, tucking is performed at least twice opposite the direction of the first tuck, so that a folded edge of the product tucked at least twice comes to lie above the tucked, first end.    In a device for performing this process, there is attached, to a conveying device (1), a first folding station (8) with folding flaps that can be pivoted around pins parallel to conveying direction (11), and in the conveying direction, after first folding station (8), a flap (22) that can pivot around a pin running crosswise to conveying direction (11) is attached and the conveying device comprises a transfer point to a device for multiple tucking of the exposed end of the folded dough sheet.
