Inventor: MORIYAMA JIRO
IPC: H04N1/52
Filed: 1993-10-29
Abstract: Whether or not a color image is present adjacent to a black image is discriminated. Whether the black image is formed using a black ink or a plurality of color inks C, M, and Y is determined in accordance with the discrimination result. When the black image is formed using the plurality of color inks, it is recorded using a repetitive pattern of two of C, M, and Y so as to prevent blurring with the color image, and to improve fixing characteristics by decreasing the total ejection amount. <IMAGE>

IPC: H04W8/20
Filed: 1993-04-07
Abstract: ABSTRACT     A signalling protocol 400 for use in communication between cellular telephone exchanges 10,  12,  and 14.   The signalling protocol 400  for messages  is  structured  to  include software package data 478, 572, 620, 670 which identifies the particular software package or version used by the message source.   This enables the cellular telephone exchange  10,  12,  or  14 which receives  the  signalling  protocol  400  to  understand  the capabilities and features incorporated in the sending cellular telephone exchange 10, 12, or 14, by virtue of the version of the software package incorporated in the sending cellular telephone exchange 10, 12, or 14.  Although the signalling protocol 400 is described as used by three cellular telephone exchanges, 10, 12, and 14, any number of like systems can use the signalling protocol 400.

Title: Improved marine anchor
Inventor: BRUCE PETER
IPC: B63B21/32
Filed: 1992-05-21
Abstract: A marine anchor (1) has an anhedral fluke (2) with a shank (3) attached thereto including an anchor line attachment point (10). A rear plate assembly (4) behind the fluke (2) is inclined at an obtuse angle (.alpha.) to the fluke (2) and serves to provide a turning moment about the attachment point (10) countering turning moments produced by friction effect on the fluke and the shank and by edge resistance during anchor burial to give improved anchor holding power while soil escapes passage (5) between the rear assembly (4) and the fluke (2) allows escape of sand and soft mud passing over the fluke. Peripheral edges (4A) of the rear assembly (4) are shaped to cause rolling of the anchor to a burial position.  An upturned toe portion (9) at the front of the fluke encourages effective anchor operation in clay soils while also facilitating rock gripping by the anchor.

IPC: G03B1/36
Filed: 1994-01-13
Abstract: Motion Picture Projection Apparatus Abstract A motion picture apparatus for the projection of motion picture film which advances the film through the projection sequence by forced air.  The film is initially placed into successive looped configurations formed by a cam-driven  flipper.  The  loops  and  thus  the  film  are advanced through the projector pathway by a forced air blower  which  propels  the  loop  through  a  projection pathway. Vacuum pressure is also applied to the film through a gate to secure the film to a gate with linearly arranged  register  pins  steadying  the  film  over  a projection aperture.   The film is rewound through the projector by a motorized rewind with a positive pressure applied to the film through the gate.

Title: Method and apparatus for shaping hollow-section workpieces
Inventor: BARTELS HERMANN
IPC: B21D26/037
Filed: 1994-03-22
Abstract: ABSTRACT OF THE INVENTION   In a method and apparatus for shaping hollow-section workpieces such as tubes of metal, the workpiece is introduced into a pressing mold whose internal contour corresponds to the workpiece shape to be produced. After closure of the pressing mold a pressure medium in the form of solid matter particles or elements such as steel balls is pressed by means of a bar into the workpiece, applying it against the internal contour of the pressure mold. In that operation  an upsetting movement of the workpiece is superimposed on the bar movement. The bar can be pressed into the workpiece in two or more steps, in which case the pressure medium is further advanced by means of a pressure cylinder between the respective steps after a respective withdrawal movement of the bar.

IPC: B65D21/04
Filed: 1994-08-26
Abstract: GRAPE LUG                  ABSTRACT OF THE INVENTION A stackable and nestable container is provided which comprises a bottom surface and two pairs of opposed side walls integrally joined with the bottom surface and each other to form a substantially rectangular open-top container. The uppermost surfaces of the side walls collectively form an upper container rim. A container lid is adapted to be received along the upper container rim. Ventilation apertures are formed in each of the side walls. Also, each side wall includes a pair of column sections. Each column section includes a recessed portion, an inner shelf, and a lower column support. The column sections form outer surfaces which project outwardly away from the side walls. By using the column section design, all the support geometry for the container is located in the corners of the container The upper container rim comprises a double thickness of material around substantially its entire periphery. The upper container rim comprises a single thickness of material only along those surfaces located adjacent to the recessed portions of the column sections. With this design, the double thickness construction of substantially the entire upper container rim provides the container with sufficient high strength for stacking. Further, the single thickness recessed portions of the column sections provide suitable surfaces for a nesting configuration. However, the high strength of the container is maintained in potentially weak single thickness areas by the double thickness construction of the lower column supports. Also, with the double to single thickness design, the outer surfaces of the column sections are configured so as to closely abut the column sections of a similarly shaped container when the containers are juxtaposed.
