Abstract: A cleaning apparatus (100) designed for use in conjunction with a lithographic printing member associated with a rotary cylinder (P) comprises an elastomeric (preferably foam) roller (110) for making rotating contact with the printing member; a fixed screen (112); and a brush (112) in rotating contact with the roller (110) and with the screen (114). The roller (110) may extend axially at least across the imaging region of the printing member (i.e., that portion of the imaging member that actually receives the image to be printed). The elastomeric roller (110) removes imaging debris from the cylinder (P), while the brush (112) removes from the roller (110) debris that would otherwise accumulate therein. As the brush (112) rotates past the screen (114), it sheds debris withdrawn from the roller (116); debris passing through the screen (114) may be collected, for example, in a container (116) or removed from the system by vacuum. The system may also include one or more doctor blades in contact with the roller (110) for removing debris remaining on the roller (110) following its contact with the brush.

Abstract: A child-resistant lighter includes an actuator (7) and a latch member (8) coupled thereto.  The latch member includes a finger actuation portion (92) and an integrally formed body portion (96) having a free end. In one embodiment, the latch member is pivotally coupled to the actuator. In an inoperative position, the free end of the latch member is aligned with a blocking surface (104) of the lighter body, preventing inadvertent lighting.  In an operative position, the free end of the latch member is pivoted out of alignment with the blocking surface so that the lighter can function. During pivoting, as the finger actuation portion moves in a forward direction, the free end moves in a rearward direction. The latch member may be disposed on the rear wall of the actuator or in a longitudinally extending channel in the actuator.

Abstract: A stylus with biometric sensors captures a wide variety of biometrics while the pen is being used. The stylus is the centerpiece of a system to enable conversion from a card-based commercial transaction system to a cardless commercial transaction system. The stylus senses the prints of the index finger and thumb along with other properties, while the customer uses the stylus to sign his name. In signature verification systems currently in use, pen-like systems are used, but prints are not being measured. The stylus enables the conversion at point-of-sale terminals when used to verify signatures, and in closed environments where house cards are issued for a limited purpose or within a limited area. Initially, the stylus will replace existing pen-like systems for signature verification. Once used for signature verficiation, the credit card becomes optional. Applicants can also use the stylus to participate in government programs (such as subsidies, voter registration, and driver's licenses).

Abstract: Bimetallic plate is produced by providing a substrate (S) of a first metal and, with the preheated substrate (S) positioned in a mould cavity (34) with a major surface of the substrate (S) facing upwardly and to fill a portion of the depth of the cavity (34), a second metal is cast against that surface to form a cladding component and, with the substrate (S), to form the bimetallic plate. Prior to the cladding being cast, the major surface is rendered substantially oxide-free and is protected against oxidation. The cladding is cast by a melt, of a composition required for it, being poured at a superheated temperature whereby, with the preheating of the substrate (S), an overall heat energy balance is achieved between the substrate (S) and the cladding. The heat energy balance causes a diffusion bond to be achieved between the major surface of the substrate (S) and the cladding, and attainment of the energy balance is facilitated by causing the melt to enter the mould cavity (34) through a series of gates (44) which provide communication between at least one runner (40) and the mould cavity (34). The series of gates (44) is disposed laterally with respect to flow of the melt therethrough whereby the melt forms a laterally extending melt front. Attainment of the heat energy balance is further facilitated by causing the melt front to advance away from the gates 144), over the substrate (S) surface, at a rate which is substantially uniform across the lateral extent of the front.

Title: The use of microfluidic systems in the detection of target analytes using microsphere arrays
Inventor: GUNDERSON KEVIN
IPC: B01L3/00
Filed: 2000-05-22
Granted: 2005-05-10
Abstract: The invention relates generally to methods and apparatus for conducting analyses, particularly microfluidic devices for the detection of target analytes. The detection module of the microfluidic devices described herein are based on previous work comprising a bead-based analytic chemistry system in which beads, also termed microspheres, carrying chemistry chemical functionalities are distributed on an array substrate comprising a patterned surface od discrete sites that can bind the individual micropheres. The bead s are generally put onto the substrate randomly, and thus several different methodologies can be used to "decode" the arrays. In one embodiment, unique optical signatures are incorpored into the beads, generally fluorescent dyes , that could be used to identify the chemical functionality on any particular bead. This allows the synthesis of the candidate agents (i.e. compounds such as nucleic acids and antibodies) to be divorced from their placement on an array, i.e. the candidate agents may be synthesized on the beads, and then t he beads are randomly distributed on a patterned surface.

Abstract: L'invention concerne un procédé discontinu de production de pâte kraft dans lequel on réduit les dépôts de tartre sur les surfaces d'échange thermique. La première liqueur d'imprégnation, retirée à partir du lessiveur, est riche en matériau dissous contenant du calcium. Ce matériau, lorsqu'on le chauffe, libère le calcium, lequel forme du carbonate de calcium. Si le chauffage s'effectue au niveau d'une surface d'échange thermique, il peut en résulter un entartrage important de celle-ci. Selon l'invention, on introduit la liqueur riche en calcium dans le lessiveur, en tant que liqueur de chasse, après terminaison d'une cuisson. Etant donné que la température du lessiveur est élevée au niveau de cette étape du procédé, le matériau dissous contenant le calcium se décompose et le carbonate de calcium se précipite dans la pâte, dans le lessiveur, de sorte qu'il ne peut pas se produire d'entartrage des surfaces d'échange thermique.
