Abstract: ABSTRACT OF DISCLOSURE            This invention is related to a method and an apparatus for forming a dry web on the wire, with the fibre material being fed into at least one perforated drumlike forming element that covers essentially the whole width of the web to be formed, in which forming element fibres are in an in itself known method conveyed in the drum along the width of the web and screened through the mantle of the forming element onto the wire. To achieve such web formation as has as few disturbances as possible, the fibre material is according to the invention fed into the drumlike forming element in such a way that the bulk of the fibres, when advancing in the feeding direction toward the other end of the forming element, get screened from the forming element onto the wire, and that those fibres that do not get screened, but travel through the forming element are removed from the forming element and returned for a new defibration.

Title: Controller for electric clamp
Inventor: VAN ZEELAND DONALD
IPC: B25B5/12
Filed: 1989-06-20
Granted: 1992-08-04
Abstract: ABSTRACT OF THE  DISCLOSURE     A controller for an electric clamp closes the clamp rapidly at first, then runs at a slower speed while contacting the workpiece, and speeds up again after contacting it, to close with full clamping force.  Arrival of the clamp at the position for slowing down is directly detected by means of a proximity sensor, as are arrivals at other positions.  The speed of operation is relatively insensitive to the voltage of its AC electrical power source because an open-loop compensating signal controls the pulse duration of rectified DC pulses that drive the motor.  The controller has dynamic braking that is applied between individual pulses of pulse trains of motor current; this results in significant increase in swings of current values for a given motor speed, that reduces harmful effects of mechanical friction.  Two jogging speeds are selectable.

Abstract: The present invention provides a method and a test cell for detecting a ligand in a liquid sample. According to the method of the present invention a solution is transported along a flow path in the test cell. The solution is brought into contact with a test site visible through a window in a wall of the test cell. The solution includes a liquid sample suspected to contain a ligand and a conjugate. The test site has immobilized thereon a first protein having a binding site specific to a first epitope on the ligand. The conjugate comprises coloured particles coupled to a second protein selected from the group consisting of proteins having a binding site specific to a second epitope on the ligand and proteins which bind with the first protein in competition with the ligand. The solution is then transported to progressively produce at the test site a complex comprising the ligand for a time sufficient to visually determine through the window whether a colour is developed at the test site.
