Abstract: A tick removing device having an open sleeve with a tick removing end and an actuating end. A gripping device is disposed and movable in the sleeve. A main body is disposed within the sleeve and extends out from the tick removing end of the sleeve and provides an elongated slot that extends from an intermediate portion of the sleeve down the main body portion of the gripping device and out the tick removing end of the sleeve. The slot defines two spaced apart main body portions forming a pair of movable gripping legs that extend out from the tick removing end of the sleeve. The legs include a pair of tick gripping points. A connecting portion of the gripping device extends from the main body through the sleeve towards the actuating end of the sleeve, and includes a slotted terminal end that includes at least one locking projection. A detachably connected movable actuator button disposed within the actuating end of the sleeve has a hollow sleeve within the elongated sleeve. The actuator button includes a spring stop portion that is formed about an internal end of the actuator button. A shoulder formed internally within the elongated sleeve functions as a spring stop. A spring is engaged on one end with the actuator button and on the other end with the shoulder for withdrawing the gripping legs of the main body portion into the sleeve. A fixed spreader pin secured within the sleeve disposed within the slot of the main body portions causes the gripping legs to spread toward an open position and release of the actuator button causes the gripping device to be moved towards the actuating end of the sleeve. The sleeve then constricts the gripping legs to be moved towards a closed position.

Abstract: Les machines de fermeture de cartons ondulés actuellement disponibles utilisent une paire de têtes rubaneuses, chacune desquelles porte un rouleau de ruban adhésif sensible à la pression. Quand un rouleau de ruban fini, il est nécessaire d'arrêter la machine et remplacer le rouleau, avec une perte en temps de production. Une solution simple à ce problème est fournie par le dispositif de raccordement de ruban adhésif décrit ci-après, qui comprend un support pour le montage sur un châssis de machine de fermeture, un arbre monté de manière rotative sur le support, le support portant une broche à chaque extrémité de celui-ci pour un rouleau de ruban adhésif, une première poignée et frein sur une extrémité de l'arbre pour verrouiller de façon libérable le bras dans une position, et une deuxième poignée sur l'autre extrémité de l'arbre pour faire tourner l'arbre et le bras, un rouleau racleur et un rouleau de séparation montés sur le cadre. Un premier rouleau de ruban adhésif est distribué à partir d'une broche à une tête rubaneuse, et un second rouleau complet de ruban adhésif est placé sur l'autre broche. Lorsque le premier rouleau de ruban adhésif est presque entièrement distribué, le frein est relâché et le bras est mis en rotation pour amener le deuxième rouleau de ruban adhésif à entrer en contact avec la surface adhésive du premier rouleau. La rotation continue du bras amène le premier rouleau à s'enrouler partiellement autour du second rouleau, grâce à quoi une languette de papier sur l'extrémité avant du second rouleau est fixée sur le premier rouleau de ruban adhésif pour démarrer la distribution du second rouleau de ruban adhésif en relation de chevauchement avec l'extrémité arrière du premier rouleau de ruban adhésif. Le bras est entraîné en rotation jusqu'à ce que le rouleau utilisé passe entre les rouleaux racleurs et de la séparation, grâce auquel l'extrémité arrière du rouleau utilisé engage le rouleau de séparation et le nouveau rouleau engage le rouleau racleur. Le bras est à nouveau verrouillé en position et l'extrémité arrière de l'ancien rouleau de ruban adhésif est coupée. Le rabat résultant du vieux rouleau de ruban adhésif est pressé contre le rouleau neuf pour terminer l'épissure et distribué avec le nouveau rouleau de ruban adhésif à la tête rubaneuse.

Title: Dissolved solids control in pulp production
Inventor: MARCOCCIA BRUNO S
IPC: D21C3/24
Filed: 1994-02-25
Granted: 2003-12-30
Abstract: Kraft pulp of increased strength and bleachability may be produced with decreased consumption of effective alkali, and at a lower H factor, by keeping the dissolved organic material (DOM) concentration low substantially through the entire kraft cook, including by extracting high DOM liquid from at least one part of a continuous digester and replacing it with much lower level DOM liquid. Existing pulp mills having two-vessel hydraulic, one-vessel hydraulic, or other systems may be retrofit to provide for extractions and additions of low DOM dilution liquor (including substantially DOM free white liquor). Also, commercial size batch digesters (8 tons perday of pulp or more) can be operated with low DOM liquor to produce increased strength pulp. Using dilution with low DOM liquor also results in reduced H factor and effective alkali consumption, and increased bleachability.

Title: Method and apparatus for storing and retrieving routing information in a network node
Inventor: CONDON JOSEPH HENRY
IPC: H04L12/56
Filed: 1995-10-18
Granted: 2000-12-19
Abstract: Method and apparatus for storing and retrieving routing information in a node of a network, such as an ATM network, are disclosed.  A routing table in each node of the network stores the routing information for each active call connection through the node, for example, identified by a virtual path identifier (VPI) and a virtual channel identifier (VCI). The routing table is indexed by a modified header error control (HEC) value, which may be the actual HEC value associated with a given cell, or a value calculated therefrom.  Upon receipt of an incoming cell at a network node, the modified HEC value is calculated, to access the appropriate entry of the routing table.  The routing table preferably stores a pointer to a memory location, such as a linked list of data structures, storing the actual routing information for each connection. An intermediate node data structure preferably stores the routing information for a particular connection through an intermediate node of the ATM network, while a leaf node data structure preferably stores the routing information for a particular connection associated with a leaf node of the ATM network.  If a data structure in the indicated linked list has a VPI/VCI value matching the VPI/VCI value in the received cell header, the routing information for the next link of the call connection is retrieved, and the cell header information is validated.

Abstract: An earth formation tool measures pressure from within a borehole. A portion of the borehole wall is isolated from surrounding borehole fluids by placing a chamber of a borehole tool against the borehole wall. The chamber comprises a recess in an exterior surface of a borehole tool. Mudcake present on the isolated portion of the borehole wall is disintegrated by an ultrasonic transducer within the chamber. In this manner, there is no resistance to fluid flow from the chamber to the formation. A pressure gauge measures pressure of the chamber to indicate pressure of the earth formation. This approach can be used to make moving or stationary measurements of earth formation pressure.
