Abstract: PILGER MILL MANDREL MEASURING DEVICE                 Abstract of the Disclosure A method and an apparatus for measuring a tapered cylindrical object, such as a mandrel.  The apparatus employs a linear positioning table assembly with a slide mounting for a  laser micrometer,  an axial position stepper motor for moving the laser micrometer stepwise along the axial length of the mandrel, and an angular position stepper motor for stepwise rotation of the object. The laser micrometer measures a cross-sectional diameter of the mandrel at a plurality of angular positions of the mandrel for each one of a plurality of axial positions along the length of the mandrel.  The measurements taken at a plurality of angular positions constitute  a  circumference  profile  at  that  axial position.  The circumference profiles at a plurality of axial positions constitute the contour profile of the mandrel.   The acquired data are compared to desired mandrel contour profile data.

Title: Vertical-Type Filling and Packaging Machine
Inventor: NAGAI KATSUMI
IPC: B65B51/32
Filed: 1994-06-06
Abstract: A vertical-type filling and packaging machine for filling and packaging a filling material in a tubular film of resin has a pair of squeezing rollers rotatably disposed one on each side of the tubular film filled with a filling material.  The squeezing rollers press against the tubular film to clamp and feed the tubular film downwardly and create an unfilled region in the tubular film.  A heat sealing mechanism which is disposed downwardly of the squeezing rollers for heat-sealing and severing the unfilled region has a heater bar for heat-sealing the unfilled region and a cooling bar for cooling the portion which has been heat-sealed by the heater bar.  The heater bar and the cooling bar are successively pressable against a portion of the unfilled region while the tubular film is being held at rest.  A cutting device, which may be an independent cutting blade or a triangular protrusion on the heater bar, severs the heat-sealed portion, thereby producing a sacked product.  A plurality of film support members are disposed downwardly of the heat-sealing mechanism for gripping and holding a lower end of the unfilled region from the time the unfilled region is heat-sealed until the unfilled region is severed by the heat sealing mechanism.

Abstract: In vibratory screening apparatus, a screen unit (10) consists of a sheet of flexible mesh material (10A) having rib elements (14) of a hard rubber or like material moulded onto mutually parallel fore-and-aft side edge portions. The screen unit (10) is mounted by inserting the rib elements (14) into slit tubular holders (13) one of which is anchored to one side support member (12) in the screening apparatus and the other of which is shiftable bodily to tension the mesh material (10A) by pneumatic actuators (18) connected to a single pressure source.

Thus, changing of the screen unit (10) can be effected rapidly with reduced risk of mesh distortion due to uneven tensioning. Final tensioning is effected by shiftable support bars (20) extending fore-and-aft between the side support members (11, 12) in known manner.

Title: Recursive finite state grammar
Inventor: CHOW YEN-LU
IPC: G10L15/193
Filed: 1993-12-28
Abstract: A method and means for performing speech recognition are described. The method and means include multiple finite state grammars. The multiple finite state grammars include at least one global finite state grammar and at least one sub-finite state grammar. Each of the multiple finite state grammars includes multiple states and at least one transition arranged in a network. The transitions in the network are capable of including either terminals or non-terminals.  Each of the terminals is associated with an acoustic model, while each of the non-terminals is associated with a call to one of the sub-finite state grammars. The present invention also includes a recognition engine which performs the recognition by traveling through the global finite state grammar. As terminals are encountered, the recognition engine matches the acoustic model of the terminal to the speech signals. As non-terminals are encountered, the recognition engine calls the sub-finite state grammar associated with the non-terminal and continues performing recognition by traversing the sub-finite state grammar. In traversing the sub-finite state grammar, the recognition engine matches the acoustic model to the speech signals to continue with the recognition. Upon traversing the sub-finite state grammar, the recognition engine returns to and continues traversing the global finite state grammar at the location of the call.  In this manner, the speech signals are matched against the acoustic models in the global and sub-finite state grammars to generate textual output.          I
