Abstract: Method and device in the press section of a paper machine for detaching the web (W) from a smooth mantle face (18') of a press roll (18). In the method and in the device, a transfer zone (40a; 50a) is employed, over which a press fabric (23) or a particular transfer fabric (44) is passed so as to accomplish a closed draw of the web (W). The transfer zone (40a, 50a) as well as said fabric (23; 44) form a transfer nip (N s) or a transfer zone with the roll face (18'), At the transfer point, the temperature level (T) of the roll face (18') and/or of the web (W) is set or regulated so high that the pressure (p s) of saturated vapour of the water present in connection with the web (W) and with the roll face (18') which corresponds to said temperature level (T) is substantially equally high as, or just little higher than, the pressure (p o) that has been set to prevail in said transfer zone (40a, 50a), said pressure (p o) being preferably lower than the atmospheric pressure.

Granted: 1997-06-10
Abstract: An improved quick coupler for attaching a tool to an excavator includes a body of a pair of spaced parallel plates providing means for fixed attachment of the coupler to an end of the excavator.  The plates define a first slot with an opening facing in a first direction to engage upon a first tool and a second slot with an opening facing in a second direction to engage a parallel second tool pin upon the tool.  The body has a third plate between the spaced parallel plates.  The coupler has a latch for securing the second pin in the second slot, the latch including a coupler gate rotatably mounted on an axis transverse to the second pin axis to pivot about the axis between a first position with the pin secured in the second slot by the gate and a second position with the gate clear of the second slot.  A latch lever rotatably mounted on the coupler gate has a handle for moving the lever and a tab for engaging a third slot in the third plate.  The latch lever pivots between a first position with the tab engaged in the third slot to resist rotation of the gate and a second position with the tab clear of the slot to allow rotation of the gate.

Title: Method and device for estimating transmitted signals in a receiver in digital signal transmission operations
Inventor: JAMAL KARIM
IPC: H04L27/01
Filed: 1994-06-23
Granted: 2005-04-12
Abstract: In a digital signal transmission system, a receiver (14) receives a signal (R(T)), wherein the signal bandwidth of the system exceeds the system symbol rate. A correlation and sampling circuit (15) receives a baseband signal (y(T)), samples (21) the signal eight times (y(k/8)) per symbol time (TS), correlates (23), generates a channel estimate (~F) and down-samples the sampled signal (y(k/8) ) to form an observed signal (y (k/2)). This signal is filtered in a prefilter (26), whose output is sampled at symbol rate (27, TS/1) and the obtained signal (z(k)) is delivered to a channel equalizer (17) which performs a viterbi algorithm with non-quadratic metric calculation and generates estimated symbols (~D(k)).      A channel estimation filter (31) receives a symbol sequence which contains alternate zero-value symbols (.OMEGA.) and the estimated symbols (~D(k)) and generates an estimated signal (~(k/2)). An error signal (e(k/2)=y(k/2)-~(k/2)) is generated and used to adapt (34) the channel estimate (~(k/2)) and also to generate (35) weight factors (.alpha.(k/2)). The coefficients (~(k/2)) of the prefilter (26) are generated as a function of the channel estimate (~(k/2)) and the weight factors (.alpha.(k/2)).      Coefficients are generated in a metric calculation filter (39, ~(k)) by convoluting the channel estimate (~(k/2)) with the prefilter (~(k/2)) and are used to generate the estimated symbols (~D(k)). The transmisson channel, excluding the prefilter (26), is estimated explicitly so as to enable fast channel changes to be followed. The use of the weight factors (.alpha.(k/2)) enables a short channel estimate to be used. The insertion of the zero-value symbols (.OMEGA.) simplifies adaptation (34) of the channel estimate (~(k/2)).

Abstract: A medical device for advancing or retracting an elongate member is disclosed. The device is made up of a flexible tube. The elongate member is connected to a bead. The bead and elongate member are disposed axially within the tube. An advancer is provided which squeezes the walls of the tube together around the bead. The elongate member is thus advanced or retracted in the tube. The bead is provided with grooves to facilitate the flow of fluid through the tube. The elongate object may be an obturator or a probe for detecting a physiological parameter. Also disclosed is a a method for advancing or retracting an elongate member. The method has the steps of connecting the elongate member to a bead-like object, enclosing the elongate member and the bead within a hollow flexible tube, squeezing the tube near the bead-like object and imparting a substantially axial force to the tube such that the force is transmitted to the bead, thereby advancing the bead and the elongate object axially along the tube.

Abstract: An improved rotor end winding assembly for an electrodynamic apparatus includes a stack of conductive straps that are configured to turn about an end turn portion of a rotor and include a top strap, a bottom strap and a number of intermediate straps that are stacked between the top strap and the bottom strap. A space defined between the rotor shaft and the bottom strap is divided into a high pressure zone and a low pressure zone by a zone block. A stepped coolant passage defined in the stack includes an ascending passage that leads from the high pressure zone toward the top strap and in the direction of the zone block and low pressure zone, and a descending passage that leads from the ascending passage to the low pressure zone. As a result, coolant will flow from the high pressure zone to said low pressure zone to efficiently cool said stack of straps.

Abstract: A scanner of this invention can read an object to be read having a width larger than that of the distal end portion of a scanner main body when the object is read by bringing the scanner main body close to or into contact with the object to be read.  An exit opening for outputting a light beam externally is formed at the distal end portion of the scanner main body.  An LED for generating a light beam, and a solid-state image pickup element for receiving the light beam which is generated by the LED, is output via the exit opening to have a predetermined irradiation width, and is reflected by a barcode, are arranged in the scanner main body.  A gap portion for increasing the irradiation width of the light beam to be larger than the width of the distal end portion of the scanner main body at the position of the distal end portion is formed at the distal end portion of the scanner main body having the exit opening.  Therefore, when a barcode is read by bringing the scanner main body close to or into contact with the barcode, the gap portion can increase the width of the light beam to be larger than that of the distal end portion at the position of the distal end portion of the scanner main body, and therefore, a barcode having a width larger than the width of the distal end portion of the scanner main body can be read.

Abstract: Undesired noise signals associated with the battery utilized in a telephone battery feed circuit are minimized.  In one embodiment, the noise voltage is amplified and inverted in phase and added back to a location on the ring line in order to provide substantial cancellation of the original noise voltage which would have appeared at the same location.  In another embodiment, the noise voltage coupled to the ring line is reproduced as a replica signal. The replica signal is added in series with the tip line so as to provide equal phase and magnitude relationships relative to earth ground, thereby effectively canceling the noise current which would have flowed from the original noise source.
