Title: Transfer apparatus providing improved transfer material guidance along a feed path to an electrophotographic image carrier
Inventor: KOIZUMI HIROMITSU
IPC: G03G15/00
Filed: 1991-04-08
Abstract: A transfer apparatus including a photoreceptor drum having a transfer position, feeding rollers for feeding out a sheet of paper upward obliquely, and a guide member provided between the feeding rollers and the photoreceptor drum and having a guide surface on a lower surface thereof to guide the paper to the transfer position along the guide surface.   In the transfer apparatus,  the structure is  simplified since the paper is guided by the single guide member.  Moreover, the feeding of the  paper  can  be  performed  smoothly,  since  frictional resistance is produced only on one side of the paper.   In addition, the guide surface is formed on the lower surface of the guide member, so that the paper can be supplied to the transfer position of the photoreceptor drum stably.

Abstract: S  P  E  C I  F  I  C  A  T  I  O  N       IMPROVEMENTS IN OR RELATING TO GUIDING OF A             TOOL ALONG A SUBTERRANEAN PATH   ABSTRACT OF THE DISCLOSURE            In order to guide a tool along a subterranean path close to the surface, as is required to cross a river for example, the tool includes a magnetic detector and a transmitter loop is positioned as a reference for the tool at  the  surface.    In  one  measurement phase,  a  direct current is caused to flow in one direction in the loop and the resulting magnetic field in the vicinity of the tool is detected by means of the magnetic detector.  In another measurement phase, a direct current is caused to flow in the  opposite direction  in  the  loop  and  the  resulting magnetic field in the vicinity of the tool is detected by means of the magnetic detector.  Processing techniques are used  to  determine  positional  information  using  the detected magnetic field values and tool orientation data, and steering of the tool may be effected as required on the basis of such positional information.   The technique permits guiding of a tool along a subterranean path with high accuracy and without requiring non-standard detection and processing circuitry.

Title: Distributed switching cellular communication system
Inventor: AMITAY NOACH
IPC: H04W36/08
Filed: 1991-08-28
Abstract: A cellular switching system and architecture is described in which the switching associated with a call originated within one cell but now serviced within another cell is distributed among base stations which are interconnected with each other through a local area network. The routing procedure associated with the point of origin for a given call is stored in the memory of a switch of public switched telephone network. As an active subscriber crosses a cell boundary, the switch routes all packets of information for the given call to the originating base station for the duration of the call. Importantly, each base station then forwards each packet to the subscriber's current base station via the local area network. In this manner, the inventive architecture is unaffected by the increased crossing between cell boundaries since the switching associated with those calls not within the range of the initial base station is handled in a distributed manner by each base station via the local area network.

Patent CA-2052968-A1 (CA)
Title: Interleaved towel fold configuration
Inventor: CHAN MICHAEL Y
IPC: B65D83/08
Filed: 1991-10-08
Abstract: Disclosed is an interleaved L-fold towel arrangement which minimizes a number of different types of commonly occurring paper towel dispensing failures. Each towel in the interleaved stack of towels in the present invention is comprised of a sheet which has been folded in half to substantially create a two-ply arrangement. A second fold is imparted to the towel substantially to the first fold thereby creating a lead flap and a trailing flap. The lead flap begins with the first fold and thereby creates a tab end which is two-ply and which will not delaminate on dispensing. The user will thus always be grasping a two-ply product as it is being dispensed thereby minimizing tear-out and tab-out failure.      The lead flap preferably has less width than the trailing flap, thus limiting the amount of deformation which must be imparted by the trailing flap to the lead flap next to be dispensed to cause said lead flap to be drawn through the dispensing opening of a dispenser.

Title: Process for the conversion of carbonaceous feedstocks to particulate carbon and methanol
Inventor: GROHSE EDWARD W
IPC: C10L1/32
Filed: 1990-10-18
Abstract: A process for the production of a pollutant-free particulate carbon (i.e., a substantially ash-, sulfur- and nitrogen-free car-bon) from carbonaceous feedstocks (21). The basic process involves de-oxygenating one of the gas streams formed in a cyclic hy-dropynolysis (10) methane pyrolysis (34) process in order to improve conversion of the initial carbonaceous feedstock. De-oxy-genation is effected by catalytically converting carbon monoxide, carbon dioxide, and hydrogen contained in one of the, pyrolysis gas streams (44), preferably the latter, to a methanol co-product. There are thus produced two products whose use is known perse, viz.; a substantially pollutant-free particulate carbon black (53) and methanol (49). These products may be admixed in the form of a liquid slurry of carbon black in methanol.
