The sheet feeding device has a support surface for a sheet stack, displaced relative to a sheet feed head (30), for extracting the top sheet from the stack, via a displacement mechanism. The movement control for the displacement mechanism responds to the detected position of the top sheet relative to the sheet feed head, indicated via an edge sensor, to provide a control signal at regular time int...

The sheet feeding device has a feed head (30) for extracting the top sheet from a sheet stack, positioned on a support surface (14) which is displaced relative to the feed head. The displacement mechanism for the sheet stack support surface is coupled to a displacement control, responding to detected sheet stack parameters, e.g. the stack height, for controlling the speed of the displacement motor...

An automatically controlled cutting machine for working on limp sheet material utilizes positive air pressure and vacuum to hold the material in place during a work operation. The level of the pressure is set or regulated with a pressure sensor to develop an appropriate holddown force and to minimize the disturbance to the material surrounding the work operation. The distribution of the airflow on...

The system obtains an estimated curve of motion (La) of a vehicle from a first group of scanning data (X1,Y1-X5,Y5). An alarm region (WA1a) is determined between a pair of circular arcs shifted by \1 m from this curve, and a pair of straight lines (Y1,Y5). Another curve (Lb) is estimated similarly from a second group of data (X3,Y3-X5,Y5), and another alarm region (WA1b) is determined. The radii ...

The system is built around an electronic control circuit (5) linked to a radar range and azimuth meter (3) and sensors of road speed (21), brake application (23) and throttle flap position (25). Alarm loudness and sensitivity are adjustable by other inputs (11,13). Commands are produced for a range indicator (7), alarm sounder (9), throttle and brake actuators (15,17), automatic traction control (...

Microporous battery separators made of polyolefins and fillers, for lead/sulphuric acid accumulators, are characterized by the fact that the polyolefin component has an average molecular weight of over 5,000,000, and that the content of extractable oil in the finished separator is less than 1 %.

In a decanter centrifuge, which comprises an outer drum (1) and an inner drum (5) concentric therewith, the two drums being rotatable at different speeds around a common centre axis, said inner drum (5) carries several blades (6, 7) arranged to convey axially in the outer drum (1) sludge having settled on the inside of this drum. The blades (6, 7) are placed in parallel blade rows, each of which e...

An interlock mechanism for a food product slicer that prevents the carriage support of a reciprocating carriage from being removed from the slicer housing unless the gauge plate of the slicer is closed and the carriage is positioned along a predetermined portion of the path of reciprocation of the carriage. The interlock mechanism includes a pivoting interlock plate and a stationary interlock bar....

In a tube (2), of which an inner space is divided by a partition (20) into an air chamber (3) adapted to be filled with air and a seal agent chamber (7) adapted to be filled with a seal agent (8), a ratio R (R = B/A) of a cross-sectional area B of the tube (2), which is filled with air to expand, to a cross-sectional area A of the tube (2), which is received in a tire (1) while deflated, is set fr...
