Title: Cutting arrangement for a material web
Inventor: HELLER MARTIN
IPC: B26D7/26
Filed: 1999-02-10
Abstract: A cutting arrangement for a material web, especially photographic copy material in a photographic copier includes a knife roller (5) and a drive (3, 4, 6 to 9) for reciprocating the knife roller (5) between two turnaround positions (S1, S4) transverse to the material web (M) to be cut, to thereby carry out one cut respectively. At least two starting positions (S1, S2 or S3, S4) are provided for each of the two cutting directions which are associated with different widths of the material web (M). The drive (3, 4, 6 to 9) commences the cutting movement of the knife roller (5) respectively at that starting position (S1, S2 or S3, S4) associated for one cutting direction with the respective material web width and moves the knife roller (5) after completion of the cut to the respectively closest turnaround position (S1, S4) and from thereback to the starting position (S4, S3 or S2, S1) associated for the other cutting direction with the respective material web width, provided that the latter starting position (S4, S3 or S2, S1) does not coincide with a turnaround position (S1, S4). The arrangement of different starting positions for material webs of different width makes time savings of up to over 50% possible.

Title: Flow control of frame based data over a synchronous digital network
Inventor: WIGGINS DAVID WILLIAM
IPC: H04L12/46
Filed: 1999-09-02
Abstract: A transmission apparatus and a method for operating the apparatus comprises means for controlling flow of frame based data transmitted from a local frame based data channel interface over a synchronous digital network. The method of operation comprises the transmitter receiving frame based data at a first rate whereafter a buffer is configured to receive the frame based data. A data amount threshold level for the buffer is predetermined whereafter, with respect to the threshold level, an amount of transmitted frame based data that has been received is monitored. In response to monitoring the amount of data received, a signal, in the form of a pause frame, is generated wherein the signal is configurable to adapt the rate of transmission from the frame based data channel interface. Working in conjunction with the transmission means there is also provided a receiver for controlling flow of frame based data, received from a synchronous digital network, to a frame based data channel interface. The receiver is configured to receive the frame based data at a first rate whereafter a buffer is configured to receive the frame based data. Upon pre-determining a data amount threshold level for the buffer an amount of frame based data received is monitored with respect to the threshold level.  In response to monitoring the amount of data received, a signal is generated in the form of a pause frame, wherein the pause frame signal is configurable to adapt the first transmission rate of the frame based data over the synchronous digital network to a second rate. In this way, the rate of transmission from a local Ethernet switch may be controlled and the rate of receipt of Ethernet based frame data from a synchronous digital network may be controlled. In the latter case pause frames may be incorporated into one or more synchronous digital hierarchy virtual containers.

Title: Method for decomposing bromic acid by photocatalyst and apparatus therefor
Inventor: KUSUMI MIYOKO
IPC: A62D3/00
Filed: 1999-09-07
Abstract: The invention relates to a method for decomposing bromate ions contained in a liquid. The method includes the sequential steps of bringing the liquid into contact with a photocatalyst; and irradiating the photocatalyst with a light ray having an energy that is not lower than that of a band gap of the photocatalyst, thereby generating a photocatalytic reaction to decompose the bromate ions. The invention further relates an apparatus for decomposing bromate ions contained in a liquid. The apparatus includes a first section for generating therein a photocatalytic reaction to decompose the bromate ions a photocatalyst adapted to be brought into contact with the liquid in the first section and a light source for irradiating the photocatalyst with the light ray such that the photocatalytic reaction is generated in the first section when the photocatalyst is in contact with the liquid. Thus, it is possible to efficiently and stably decompose the bromate ions.      The photocatalyst may be at least one metal oxide including titanium and a metal having an electronegativity lower than that of titanium. In this case, it is possible to omit pH adjustments of the liquid before and after the photocatalytic reaction.

Title: Corner brace for extention ladders
Inventor: POPIK DARREN MICHAEL
IPC: E06C7/48
Filed: 1999-10-29
Abstract: Users of extension ladders often face the problems when dealing with corners of buildings. Many times, work needs to be done on the corners of a structure, but extension ladders are not designed for placement against a corner. This device has been designed to solve this problem by means of a special brace that will attach to any extension ladder, and allow placement against corners. It will now make such things as construction work, painting, cleaning walls, doing roofing work, or hanging Christmas lights much easier to do. More importantly, it makes such tasks safer, as it will greatly reduce the need to lean or position oneself or the ladder in an awkward manner that would otherwise be required to get to those hard-to-reach places.

Title: Dust detector tube
Inventor: VOLKWEIN JON C
IPC: G01N15/00
Filed: 1998-06-26
Abstract: A personal sampling method and apparatus for real time respirable dust dosimetry for dust exposure assessment is provided to aid in assuring the respiratory health of workers. An embodiment uses a low flow-rate gas sampling pump for differential pressure measurements across a glass fiber collection filter in a disposable detector tube (12) or dust detecting device coupled to the pump inlet. The dust detecting device includes an elongated tubular element (12) having the filter (30) positioned betwen proximal and distal ends of the tube (12) for trapping dust mass. A pressure transducer (16) at the proximal end (36) measures the pressure from the flow of gas. The pump draws the flow of gas through the dust detecting device from the distal end (38) towards the proximal end (36) trapping the dust mass at the filter (30). A differential pressure across the filter (30) determined using the pressure from the flow of the gas in the proximal end (36) of the tubular element measured by the pressure transducer (16) is indicative of cumulative dust mass trapped at the filter (30).
