Abstract: ABSTRACT          A simulator for simulating on a test sheet the actions of a dryer section of a paper making machine.  The simulator includes a closed chamber to which there is connected a temperature and humidity control system to maintain the chamber in constant temperature and humidity during a test.  A dryer fabric web is mounted within the chamber and is so guided as to have two parallel runs thereof in closely spaced relation.  A holder is provided for mounting a test sheet between the two runs.  Dryers are mounted above and below the two runs.  The dryer fabric has openings therein which are selectively positioned in centered relation along the two runs so that the upper dryer may pass through an upper opening, pick up a test sheet and press the same against the dryer fabric of the lower run.  Then the dryers are moved upwardly, the dryer fabric shifted the align the other opening along the lower run and then the lower dryer may pass through the lower opening and engage the test sheet from the opposite side so as to force the same upwardly against the dryer fabric of the upper run.  The dryers may have circumferentially spaced separate heads and the dryers are mounted for timed rotation to present a new head upon each engagement of the test sheet by a respective one of the dryers.

Abstract: DIGITAL HANDSFREE TELEPHONE           Abstract of the Disclosure In a loudspeaking telephone arrangement, there are separate channels for outgoing speech (A-Tx) and incoming speech (A-Rx), and the channels are sampled at intervals.  The results of these samplings, which represent the amplitudes of the speech in those channels are each compared by a microprocessor with a preset threshold.  The background noise level is also sampled and the result used to adjust the speech channel threshold.  Each channel has an attenuator, and that is adjusted so that attenuation is reduced in the presence of speech and increased in the absence thereof.  The adjustment on the basis of background noise enables the current state of the channels to be taken into account.

Abstract: ABSTRACT OF THE DISCLOSURE   A novel system is provided to maintain electrical continuity between a point at the tow cable termination wrapped on the exterior of the rotating drum to a fixed termination external to the drum, located on the winch base. The system is an improvement in an apparatus for transferring cable between a driven rotatable spool and a fixed spool where the rotatable spool is mounted on a stub shaft and the fixed spool is coaxially mounted with respect to the rotatable spool along a common axis.  The improvement combination comprises an arm which is secured to an axle which, in turn, in the absence of other constraints, would be freely rotatable mounted on the stub shaft. The arm extends in a direction substantially perpendicular to the common axis for rotation around the axis of rotation of the driven rotatable spool. A planetary pulley is mounted for rotation at the outer end of the arm, the radial plane of the planetary pulley being substantially parallel to the common axis, the planetary pulley being mounted so as to accommodate cable as it is being transferred between the rotatable spool and the fixed spool. Positive driving structure for the arm is provided which includes an element which is secured to one face of the axle, and is adapted to be in driving contact with an actuatable, cooperative member which is operatively associated with the driven rotatable spool.  Finally, positive braking structure for the arm is provided which includes an element which is secured to the other face of the axle, and which is adapted to be in driving contact with an actuatable cooperative member which is operatively associated with said fixed spool.  In use, rotation of the rotatable spool in a first direction causes the positive driving means to be actuated, and causes the arm to rotate out of the influence of the positive braking structure around the arm in the same direction of rotation as the rotatable spool at the same speed of rotation as that of the rotatable spool.  Rotation of the rotatable spool in the second direction causes the positive braking structure to apply a braking force to the rotation of the axle, and causes the arm to be rotated out of the influence of the positive driving structure, thereby to control cable tension.

Abstract: Abstract of the Disclosure:         In an encoder for encoding an input signal (AA) into a sequence of excitation pulses (GG) with reference to an autocorrelation signal (DD) and a cross-correlation signal (CC) derived from the input signal, a cross-correla-tion controller (40) controls the cross-correlation signal in response to the autocorrelation signal and the excitation pulse sequence by producing a control signal (HH).  Both of the cross-correlation and the autocorrelation signals are concerned with a current frame of the input signal and a part of the following frame.  The control signal appears in the following frame to be subtracted from the cross-correlation signal in a subtractor (31) and to modify the cross-correlation signal into an adjusted cross-correlation signal (EE).          Although the adjusted cross-correlation signal lasts for the current frame and the part of the following frame, an excitation pulse generator (32) produces the excitation pulses only within the current frame.

Abstract: A PROCESS FOR THE PRODUCTION OF SOLID POLYISOCYANATES OF RETARDED REACTIVITY, POLYMER-COATED, FINELY DIVIDED POLYISOCYANATES AND THEIR USE                    ABSTRACT OF THE DISCLOSURE          This invention relates to the production of polymer-coated, finely divided polyisocyanates by mixing (A)  solid, finely divided polyisocyanates (preferably dimeric diisocyanates or urea diisocyanates) with (B)  polyisocyanates differing in composition from those mentioned under (A) (preferably (cyclo) aliphatic polyisocyanates, such as biuretized diisocyanates or trimers or NCO-prepolymers), in quantities of from 0.05 to 50 parts by weight, and preferably in quantities of from 0.2 to 25 parts by weight, of (B) per 100 parts by weight of (A).  The solid polyisocyanate particles surface-modified by covering with polyisocyanates (B) and then reacted with (D)  isocyanate-reactive compounds containing reactive hydrogen atoms or with compounds free from active hydrogen atoms which form polymers with isocyanates in sub-equivalent to substantially equivalent quantities (preferably 0.5 to 1.0 equivalent per NCO-equivalent), in the presence of (C)  inert, weakly polar organic solvents, (for example aliphatic hydrocarbons or relatively long chain dialkyl ethers), plasticizers, polyols or aromatic polyamines.

Abstract: ABSTRACT             OPTICAL SENSORS FOR DETECTING PHYSICAL PARAMETERS           To  detect  a  physical  parameter  such  as pressure,  temperature,  acceleration  or  force,  the physical parameter is allowed to influence the movement of a light transmitting piezoelectric member.  Light is supplied to the member and the member is vibrated in a direction  transverse to the light transmitted in the member.  The vibrations of the member are modulated by the   physical  parameter.  The  modulations  of the vibrations modulate the light transmitted by the member.          The modulations of the light transmitted by the member are then detected to detect the physical parameter.  In some embodiments   the   physical   parameter   causes   non-vibrational relative motion between two flexible light transmitting members.  The change in the amount of light transmitted between  the  two members  is detected  for detecting the physical parameter.

Abstract: Abstract of the Disclosure An endovascular stent formed of stainless steel wire of 0.018 inches diameter and arranged in a closed zig-zag pattern.  The stent is compressed into a reduced size shape of an outer diameter which is many times smaller than its expanded shape.  The stent is positioned in a passageway in the vascular system by means of a sheath while the stent is retained in the compressed reduced size shape.  A flat-ended catheter is used through the sheath to hold the stent in place in the passageway while the sheath is withdrawn from the passageway allowing the stent to expand in the passageway into its expanded shape to hold the passageway open and enlarged.  Other possible applications of the stent are in the respiratory, biliary and urinary tracts to reinforce collapsing structures.
