Abstract: A method and apparatus is achieved for creating or restoring a high friction surface to a drive roller (52). Abrasive pads (12) define a scrubbing surface for acting upon a media roller's surface (54-58). As the roller's surface is scrubbed, creping occurs which increases the surface's coefficient of friction be-tween the roller and media sheet ("COFB(?)"). In one embodiment, the creping apparatus is formed by a pair of plates (16, 18) hinged along one edge (30) and open along an op-posite edge (28). A spring (19) is positioned between the plates bias-ing the plates apart at the open end. One or more abrasive pads are attached to the outer surface of one plate (18). To create or restore a high friction surface, the apparatus (10) is positioned adjacent to the roller (52). By approximately defining the force applied between the roller (52) and abrasive pads (12) and by using an abrasive pad of known grit, initially surface contaminants, if any, are scrubbed from the roller surface (54-58).

Abstract: A conductor section for a stator core of a polyphase dynamo-electric machine. The stator core is provided with a series of elongated parallel slots for receiving respective conductor sections. The conductor section includes two parallel sides (6, 8) having a rectangular cross section and designed to engage the corresponding parallel slots in the stator core such that the two sides define a plane. Said conductor section further includes at least one conductor head (10) having a rectangular cross-section and linking two adjacent ends of the two parallel sides. The head has a U-shaped body when seen from above perpendicularly to the plane, and a sinuous body when seen in front view along said plane. The head has upper and lower opposite surfaces. The upper surface faces one side of the plane whereas the lower surface faces the opposite side of the plane. The conductor section advantageously enables the efficiency of a motor to be increased since the stator slot space factor is high, while at the same time enabling the sections to have small heads, thereby reducing motor weight and heat loss.

Abstract: System and apparatus particularly suited for tracking a radiopharmaceutical present within a lymph duct and locating a sentinel node within which the radiopharmaceutical has concentrated. A smaller, straight, hand-held probe is employed carrying two hand actuable switches. For tracking procedures, the probe is moved in an undulatory manner wherein the location of the radiopharmaceutical containing duct is determined by observing a graphics readout developed preferably employing a circularly accessed data memory. When the region of the sentinel node is approached, a switch on the probe device is actuated by the surgeon to carry out a sequence of squelching operations until a small node locating region is defined. At that point in the procedure, the straight small probe will be pointed at and in adjacency with the radiopharmaceutical containing sentinel node. The probe-mounted switches areconfigured to apply preset current levels upon the probe pre-amplifier power supply. These levels are detected, identified by a discriminator and emulating signals are generated. A sterilizable remote switch provides a squelch threaded level trim function.

Abstract: An ATM-switch for high transmission rates is built of primary switch cores (7). A path for a cell through the switch is determined at the arrival of the cell at the switch and this path is coded as a control word, which is transferred through the switch in parallel to the cell itself. The control word indicates directly how the transfer through each primary element of the switch is to be made.  Each primary element (7) must only have two inputs (13) and two outputs (21). The control word then consists of one bit for every stage of primary switch elements in the switch and this bit indicates directly the output from which the cell is to be forwarded from a considered switch element. The switch cores (7) are constructed of intermediate storage memories (9), one for each pair of one input (13) and one output (21), and these intermediate storage memories can have a rather limited capacity for storing only a few cells together with their associated control words.  The control word indicates to a cell arriving at an input the intermediate storage memory (7), where the cell is to be intermediately stored.  The intermediate storage memories can be shift registers and independent units take care of the storing of cells and the forwarding (33) of cells from the switch core (7).
