Title: Gradation record printer
Inventor: MITSUDA HIROSHI
IPC: B41J2/36
Filed: 1991-01-31
Abstract: ABSTRACT OF THE DISCLOSURE       A gradation record printer in which an amount of energy applied to a thermal head is controlled in response to a gradation level of an input image signal to print an image on a printing medium with gradations.   The printer comprises a gradation density detecting unit for storing data of standard density patterns with respect to address values corresponding to gradation levels and for outputting a coincidence signal when data supplied from an outside of the gradation density detecting  unit  substantially  coincides  with  the  data  of standard density patterns, a gradation test print circuit for applying data of different amounts of printing energy to the thermal head sequentially to make a gradation test print on the printing medium,  a density detecting sensor for detecting densities of the gradation test print and for applying a detection output from the density detecting sensor to the gradation density detecting unit, and a memory element for storing the data of different amounts of energy with respect to address  values  corresponding to  the  gradation  levels  in response to the coincidence signal from the gradation density detecting unit.  In practical printing, the input image signal is applied to the memory element, and the data for the amounts of printing energy corresponding to gradation levels of the image signal is read out of the memory element thereby to perform a  printing  operation.   Accordingly,  the printing operation can be performed with the printing energy suitable for the thermal characteristic of the given printing medium, and   the   resultant   print   is   excellent   in  gradation characteristic.

IPC: D21F3/02
Filed: 1991-07-11
Abstract: A press blanket for a press device in a paper making machine, or the like, is formed of an elastomeric blanket material and fully embedded layers of reinforcement threads. The radially inner layer is formed of longitudinal threads which extend parallel to the axis of the press blanket. The radially outer layer is formed of circumferential threads which are wound in the direction of blanket motion and are wound generally helically. The threads are fully surrounded by the layer of homogeneous elastomeric material, that is formed from a single pouring. The circumferential threads have a diameter of at most 1/500 of the outside diameter of the fully rounded press blanket. In a unit area of the press blanket, the tensile strength of the circumferential threads is at least 40% greater than the tensile strength of the longitudinal threads. An apparatus for forming such a press blanket includes a rotatable pouring cylinder on which the longitudinal threads are supported, an elastomeric material pouring nozzle which moves longitudinally over the pouring cylinder and an unwinding device for delivering the circumferential threads in a helical manner and located just after the pouring nozzle above the pouring cylinder.
Patent CA-2046837-A1 (CA)
Inventor: BRODERSEN COLE T
IPC: B60N2/52
Filed: 1991-07-11
Abstract: A device is disclosed that overrides the manual controls for filling and emptying an air suspension spring, so that the spring is not over-filled or under-filled. The device also includes a mechanism for limiting the rise of the seat suspension when the driver exits the seat. The invention has a latch bar that slides through two pieces of lubricating plastic. A ramped section of the latch bar contacts one of two switches that prevents the adjustment of a seat suspension below a minimum safe ride position or prevents adjustment above a maximum safe position. The latch bar also includes notches that are engageable with a latch pawl that is operated by a solenoid. When an operator leaves the seat, the solenoid is energized and drives the latch pawl into a notch in the latch bar. An electronic switch also enables the deenergizing of the solenoid, yet the latch pawl locks the latch bar so that the air spring does not cause a substantial rise in the seat suspension.

Title: Hydroentangled polyolefin web
Inventor: SIMPSON PENNY C
IPC: D04H1/46
Filed: 1991-08-14
Abstract: A process is disclosed for hydroentangling continuous polyolefin filament fibers to form a fabric web.      The fibers are supported on a 60 to 150 mesh screen and passed under high pressure water jets operating at at least 2000 psi and providing a total impact energy of at least 0.7 MJ-N/Kg to entangle the fibers. Preferably, the hydroentangled web is thereafter passed under finer finishing water jets operating at a pressure of between 300 to 1200 psi to redistribute the fibers. If desired, a finish may be applied to the entangled web. The resulting hydroentangled web has considerably increased visual uniformity, opacity, softness, comfort, strength and barrier properties compared to prior art webs thereby making it particularly useful as a disposable industrial garment.
Patent CA-2049228-A1 (CA)
Inventor: CHANDLEY GEORGE D
IPC: B22C13/08
Filed: 1991-08-15
Abstract: An expendable pattern of an article to be cast comprises a meltable material that expands upon heating (e.g., a wax pattern).  The pattern is invested with particulate mold material to form a thin, layered shell having a wall thickness not exceeding about .12 inch.  The thin shell wall thickness unexpectedly reduces damage and distortion to the shell during removal of the pattern therefrom by steam autoclaving.  After firing, the thin gas permeable shell mold is surrounded by a refractory particulate support media in a vacuum housing.  The vacuum housing is then evacuated to evacuate the mold cavity defined by the thin shell and concurrently a pressure is applied to the support media so as to compress the support media about the thin shell to support the shell against casting stresses when molten metal is countergravity cast into the evacuated mold cavity.

Title: System and method for directly feeding paper to printing devices
Inventor: CROWLEY H W
IPC: B65H35/00
Filed: 1991-06-05
Abstract: A unique system and method for directly feeding sheets into a printing device (80) having a moving image conducting element (82) with a plurality of images (84) placed thereon for transfer to sheet paper and having a wait station (88) for controlling the timimg of paper transfer to the image conducting element (82) provides a feeding table (104) to transfer sheets from a source to a printer stack deshingler (96) while bypassing and, thus, eliminating any need for sheet stacks. The movement of each sheet by the wait station (88) into the image transfer element signals the cutting of a sheet from a roll of continuous web (98) on the input side (122) of the feeding table (104). Once the sheet has moved into the image transfer element the absence of a sheet at the detector (144) signals transfer by the feeding table of the cut sheet to the stack deshingler (96). Simultaneously, a source of web presents and end of the web representing another sheet to a cutting unit (124). This sheet is cut when the current sheet at the wait station (88) begins movement into the image transfer element.
