Abstract: Adjustment of the sieve of a combine harvester is effected by an adjustment apparatus attached to the side wall of the combine on the outside surface. The adjustment apparatus comprises an angle bracket having a vertical screwed to the side wall and a generally horizontal plate. The lever ispivotally mounted to pivot in a plane parallel to the horizontal plate and is maintained in place by a top strap having an arcuate series of holes for pinningthe lever at a selected position. A rod extends from the end of the lever through a slot in the side wall of the combine to an adjustment arm extending rearwardly from the sieve. The adjustment position of the arm can therefore be locked in place and is visible from the outside of the combine.

Abstract: The present invention relates to a particular type of fan-forced positive pressure breathing apparatus, commonly known as Powered Air-Purifying Respirators (PAPRs). In particular the invention concerns monitoring the operation of such equipment. In a first aspect, the invention provides a powered air-purifying respirator which includes data collection means to enable the volume of air drawn through the filter to be determined. In another aspect, the invention comprises a management system for monitoring and analyzing operational data from at least one powered air-purifying respirator.  The management system includes data collection means associated with each respirator to enable the volume of air drawn through that respirator's filter to be determined, and electronic data processing apparatus into which the data collected by the data collection means is uploaded for analysis. The data processing apparatus may be partly situated on-board each respirator in order to enable alarms to be given to the wearers at appropriate times. However, a remote computer system having data processing facilities will be able to store and subsequently display the data collected, as well as enabling more sophisticated analysis.

Abstract: The present invention relates to a method and apparatus for grinding crankpins of a crankshaft.  The method is comprised of the  steps  of  mounting  the  crankshaft  between centres;  and attaching radially outer regions of the flange to a rotational drive to rotate the crankshaft about  its main axis,  via a coupling  which  is  torsionally  rigid  in  a  plane  generally perpendicular to the axis of rotation of the crankshaft but which is  readily  deformable  in  other  planes  to  accommodate misalignment.  The method further includes advancing the grinding wheel  to  engage  a  crankpin  region  of  the  crankshaft; and synchronously controlling the position of the grinding wheel whilst the crankshaft is rotated thereby to follow the planetary motion of the crankpin so as to maintain grinding contact between the wheel and the pin.   The apparatus is a grinding machine adapted  to  grind  a  crankpin  region  of  a  crankshaft  by synchronously advancing and retracting the grinding wheel as the crankshaft is rotated so that contact is maintained between grinding wheel and crankpin during grinding of the pin.  This assures that a true cylindrical surface is ground on the pin. The grinding machine is comprised of a drive unit for rotating the crankshaft, and a coupling unit which is torsionally rigid in a plane generally perpendicular to the axis of the crankshaft but  is  readily  deformable  in  other  planes  to  accommodate misalignment, for connecting the drive unit to the crankshaft.

Abstract: To accomplish a web transfer, which in reliability is comparable to the one obtained with a closed draw, in any operating environment, but especially where it is desirable to transfer a fast running tissue web (4) from the drying section of a tissue machine, e.g., a yankee dryer (2), to a reel-up (3), a web support device (10) extends across the width of the web (4) and along a predetermined run of the web (4) from the yankee dryer (2) to the re el- up (3). The web support device has a support surface (11) formed by a series  of plate member assemblies (23) having means for creating a flow of air in t he direction of the web run. Between the web (4) and the support surface (11) t he flow of air forms an air layer (15) of reduced static pressure, so as to stabilize the web (4) against flutter. The predetermined run may extend through a calender (7) and past scanner equipment (8). Pneumatic tail threading capabilities may be included.

Title: A rolling apparatus and a rolling method
Inventor: SAKO AKIRA
IPC: B21B37/68

Granted: 2004-11-23
Abstract: The present invention aims to provide a rolling system and a rolling method capable of avoiding the occurrence of a pinch fold by effectively preventing the zigzag movement of a rear end portion of a material to be rolled.    The rotational speeds (rolling speeds) of work rolls (2) of a rolling mill stand (F1) from which the rear end of a plate material (6) releases, and a succeeding rolling mill stand (F2) are controlled to the same value.      Moreover, the tension between the rolling mill stand (F1) and the rolling mill stand (F2) is controlled to zero. The difference in tension between a work side and a drive side can be made null between the rolling mill stand (F1) and the rolling mill stand (F2).      Similarly, the difference in tension between the work side and the drive side can be made null between the plurality of rolling mill stands (F2 to F n) during release of the rear end of the plate material (6).

Title: Multiline telephone including interacting call appearances
Inventor: KRISHNASWAMY VENKATESH
IPC: H04M3/56
Filed: 1999-09-01
Granted: 2003-03-25
Abstract: Interacting call appearances are realized by enabling voice input/output to be simultaneously available on any combination of call appearances at a given time on a given terminal. Consequently, a user may, for example, listen to the voice output of one or more call appearances that are active at the terminal at a given time.  Additionally, the user may direct voice input to one or more call appearances that are active at the terminal at a given time. Thus, the user, at any given time, may listen or speak to one or more parties on unrelated calls. Additionally, a user can employ more than one voice input/output device at his/her terminal. Specifically, the ability to simultaneously use more than one call appearance at a terminal at a given time is realized by separating call control from media routing and input/output control. Thus, the appearance of a call at a terminal is separated from the voice input/output that is required for the call. To this end, a user terminal or resources available to it must have the capability of mixing multiple channels of audio, as well as, the capability of multiplexing/demultiplexing voice inputs and outputs into and from line appearances.

Abstract: A method and apparatus of improving user response time during cellular hand- offs and radio frequency changes in a Transmission Control Protocol/Internet  Protocol (TCP/IP) mobile environment. In the mobile environment there is at least a mobile end station (20), a mobile data base station (22), a mobile data intermediate system (MDIS) (30) and a fixed end station (40). The MDIS (30) keeps track of the mobile end station (20) as it roams through the mobi le environment. As a result, the MDIS (30) can distinguish between delays due t o network congestion and delays due to cellular hand-offs. Further, the mobile  data base station (22) informs the MDIS (30) of any changes in the radio frequency signal, thus allowing the MDIS (30) to also recognize delays due t o changes in the radio frequency signal. With the knowledge of being able to identify the cause of the delays, the MDIS (30) is able to initiate or suppress a congestion control and recovery process.
