Abstract: A transfer apparatus (10A) is disclosed for transfer­ring a web (WA) from an upstream dryer (12A) to a down­stream dryer (14A) of a dryer section (16A). The apparatus includes a first dryer felt (18A) which extends around the upstream dryer (12A) for supporting the web such that the web is disposed between the first felt (18A) and the up­stream dryer (12A) for drying a first side (20A) of the web. The first felt roll (40) is disposed downstream relative to the upstream dryer (12A) for guiding the first felt (18A) such that the first felt diverges relative to the upstream dryer (12A) and extends from the upstream dryer to and around the first felt roll (40). A second felt roll (42) is disposed between the upstream dryer (12A) and the first felt roll (40) such that the web is disposed between the second felt roll and the first felt. A second dryer felt (28A) extends around the downstream dryer (14A) for sup­porting the web such that the web is disposed between the second dryer felt and the downstream dryer for drying a second side (34A) of the web. The second felt (28A) passes around the second felt roll (42) and extends from the second felt roll to and around the downstream dryer (14A) such that the first and the second felts define therebet­ween a web transfer section (32A), the web being sandwiched between the first and the second felts (18A,28A) between the second and the first felt rolls. A device (44) is provided for positively transferring the web from the first felt (18A) to the second felt (28A) when the first felt diverges relative to the second felt.

Abstract: There is disclosed a method for making non-run knitted fabrics on a knitting machine. 
     The fabric comprises a first not elastomeric fibrous component, a second elastomeric fibrous component and, optionally, at least a third not elastomeric fibrous components. 
     The subject method is characterized in that at least a portion of the first fibrous component is knitted into the fabric with a loose portion. 
     Thus, as the fabric is raised and sheared, or simply ground, the second elastomeric component is contracted, thereby the loose portions of the first not elastomeric fibrous components are so arranged as to be easily raised and sheared, or simply ground, in order to provide a skin-effect pile fabric in which the first fibrous component is present in essentially discontinuous lengths.

Abstract: The present invention relates to a battery alarm system for raising an alarm on recognition of the reduction of output voltage of a battery (31), wherein an analog output voltage value of a battery (31) is converted to a digital value; the digitalized values are inputted for a plurality of times at a predetermined interval to obtain the average value; and when the average value is smaller than the predetermined threshold, an alarm is raised. By obtaining an average value among voltage values inputted for a plurality of times, an alarm can be raised stably with little influence of the fluctuation of the output voltage of the battery (31).

Abstract: A color video camera according to the present invention includes a color temperature detector (16) for detecting a color temperature of a video source and a primary color separator (14), wherein matrix coefficients of the primary color separator (14) are controlled in accordance with an output of the color temperature detector in such a manner that, for example, when the color temperature of a video source is low, that is, the color of a video source is reddish, red and blue components of the video source are corrected to be weakened and intensified, respectively. On the contrary, when the color temperature of a video source is high, that is, the color of a video source is bluish, the red and blue components of the video source are corrected to be intensified and weakened respectively, whereby the degradation of the color reproducibility of the chromatic colors due to the change in the color temperature can be prevented.

Abstract: A position sensing system calculates the X-Y coordinates of a point (12) using triangulation and determines the direction in which the point (12) is moving. The triangulation calculation is based on the coordinates of at least three retroreflective elements (18) spaced apart from each other around the periphery of a two-dimensional coordinate frame, and the measured angles between the lines projected radially outward from the point (12) to each of the retroreflective elements (18). The accuracy of the measured angles is achieved by using a rotating member (30) supported by dedicated hardware and controlled by software. The member (30) rotates with a beam of light (16) generated by a light transmitting and detecting device (14) positionable at the point (12). The light transmitting and detecting device (14) receives the beam of light reflected back from the retroreflective elements (18) and generates an output signal in response thereto. A computer (22) processes the output signals for use in calculating the X-Y position of the point (12) and the orientation of the light transmitting and detecting device (14) when it is positioned at the point (12).

Abstract: A torque sensor comprises a magnetoelastically active element, and a magnetic sensor, such as a Hall effect sensor, responsive to the field of the magnetoelastically active portion. In the preferred embodiment, the magnetoelastically active portion comprises a ring of material endowed with an effective uniaxial magnetic anisotropy such that the circumferential direction is the easy axis, and magnetically polarized in a substantially circumferential direction. The ring is attached to the torqued member, such as a rotating shaft, so that application of a torque to the shaft is transmitted to the ring. The torque on the ring reorients the circumferential magnetic orientation of the ring, producing a helical magnetic orientation having both circumferential and axial components. A magnetic field vector sensor is mounted on a flux collector in a fixed position relative to the ring and oriented so that it responds only to axial magnetic field components of the ring. The output of the sensor is thus proportional to the change in orientation of the magnetization resulting from torque applied to the shaft and transmitted to the ring.

Abstract: In an angular gas cap (114) on a wire thermal spray gun (10), a forward channel extends from a rearward channel at an oblique angle thereto so as to have a lateral directional component. The rearward channel at the nozzle (54) has a channel axis parallel to the central axis of the nozzle (54) and is offset from the central axis in a direction opposite the lateral directional component. Immediately upon termination of spraying the wire is retracted into the nozzle (54). A wire positioner includes a hollow collet with the wire extending therethrough. A linear actuator (220,234) retains the collet (252) against a wall (211) to hold the collet (252) open from the wire during spraying. Upon termination of spraying the actuator (220,234) retracts to release the collet (252) from the wall so the collet (252) is sprung to engage the wire during the retraction. Upon startup the wire is advanced into the gas cap faster than normal spraying speed.
