Title: Instrumentation for measurement and calibration of thread velocity during cross-winding onto spool, determines calibration factor from two independent velocity measurements
Inventor: MARX ALEXANDER
IPC: B65H61/00
Filed: 2003-09-13
Abstract: The measurement instrument at the spool location (1), is calibrated by an additional measurement instrument built into the thread run. The velocity of the running thread (2) is measured simultaneously over an interval, by both the calibration- and spool instruments. The values are used to calculate a calibration factor (KFSP) allocated to the measurement unit and stored for evaluation of subsequently-measured results. The calibration measurements each indicate a length of thread passed through. Comparison of these lengths yields the calibration factor.

Title: Method for producing pulsing water supply with a cycle controlled bypass valve to shunt water back to the reservoir
Inventor: BRAEUMER MICHAEL
IPC: B03B5/22
Filed: 2003-11-05
Abstract: A compact method for producing a pulsing water supply, e.g. for processing systems, has a bypass with a control valve (20) to shunt the output from the water pump (12) back into the reservoir (10), or into a parallel process line (16). The bypass valve is operated by a cyclic programme and is in series with a flow control valve (22) which sets the residual pressure in the pulsed supply. The pulse profile can be enhanced by fitting a number of parallel bypass lines with control valves operated with a controlled time offset.

IPC: G05B19/418
Filed: 2003-11-13
Abstract: The invention relates to a method for maintaining field devices (F1-F4) used in process automation technology by means of a maintenance computer (WS3, WS4) of a device manufacturer, which is located in the company network LAN2 of the field device manufacturer and connected to at least one field device via the company network (LAN2), a public network (Internet) and a customer network LAN1). According to the inventive method, the public network is provided with a directory server in which a customer unit and the maintenance computer (WS3, WS4) are logged on and which, upon the customer request, assigns a session identification number, selects the network address of a relay server (R) connected to the public network (I) and transmits said address to the customer unit and to the maintenance computer (WS3, WS4).

Inventor: AMFT DIETRICH PROF DR ING
IPC: H01H73/18
Filed: 1995-05-17
Abstract: The device extinguishes arcs in a switch (1). The switch (1) has a contact point (3) in a switch or advance chamber space (4). The contact point (3) has a stationary contact piece (7) ad a movable contact piece (5). Metallic arc conducting rails (8,9) conduct an arc from the contact point (3) via an expanding region (10) of the chamber (4) into an extinguishing chamber (11). The latter is bounded in two parallel surfaces by the arc conducting rails (8,9). The remaining boundaries of the extinguishing chamber (11) and ridges (14) inside the chamber (11), running parallel to the arc conducting rails (8,9), are made of electrically insulating material. The device also includes a blowing device (15) which generates a blow out field. This presses the arc into the gaps between the ridges (14) and extends it. A flow out region (13) made of electrically insulating material may be connected to the extinguishing chamber (11). The blowing device (15) may be formed by a blowing spool arranged adjacent the expansion region (10) and the extinguishing chamber (11), or two spools one on either side of the flow outlet (13).

Patent DE-19528505-A1 (DE)
Inventor: MAAS GERHARD DR ING
IPC: F01L13/00
Filed: 1995-08-03
Abstract: In a device (1) for the optional actuation of at least one gas exchange valve consisting of two sections (2, 3) which can be connected as desired via radially movable connecting means (7), the return of the hydraulic fluid applied to the connecting means (7) to move them is to be facilitated, especially at low ambient temperatures of the internal combustion engine and hence with a highly viscous hydraulic fluid. The invention proposes to install a relief channel (20) fitted with a shutter (18) in the return line. As the volume flow rate of hydraulic fluid at such a shutter (18) is largely independent of viscosity, the connecting means (7) will be reset sufficiently quickly even at low ambient temperatures.
