Title: Apparatus for stripping threaded injection molded parts
Inventor: JOSEPH EALIAS C
IPC: B29C45/03
Filed: 1999-04-20
Abstract: An apparatus and method for ejecting threaded injection molded articles from a mold core by simultaneous application of rotational and translational force. The apparatus has a stripper ring which is rotatable about and movable along its axis. A driver rotates a stripper ring rotator in response to input from a machine ejector rod. Input from the machine ejector rod is transferred to the driver by a helically splined spindle which is axially movable relative to the driver and which engages a corresponding helically splined bore in the stripper ring rotator. Rotation of the stripper ring rotator is transferred to the stripper ring by meshing pinions. The stripper ring rotator also has a gear which meshes with corresponding teeth in a transversely extending rack to cause movement of the rack. Cams are secured to the rack and act against cam followers connected to the stripper ring to translate transverse movement of the rack into axial movement of the stripper ring.

IPC: C07H21/02
Filed: 1999-04-23
Abstract: The invention disclosed is particularly directed to a process for the purification of DNA, and is especially useful for the isolation of biologically active plasmid DNA. The process is initiated by binding the DNA to silicon carbide particles, either in the presence or absence of chaotropic agents. The bound DNA is subsequently eluted from the resin in low salt buffer or water. The resulting purified DNA is substantially free of proteins and is shown to be biologically active. The scope and diversity of the process is demonstrated here since this process can be used for the isolation of RNA and genomic DNA as well as the purification of PCR products and isolation of DNA from agarose gel slices.

Title: Method and apparatus for activating magnetomechanical eas markers while preventing formation of demagnetization field
Inventor: COPELAND RICHARD L
IPC: H01F13/00
Filed: 1997-09-12
Abstract: A two-dimensional array of magnetomechanical markers (20) is adhered to a continuous web (62). A magnetizer element (70) is scanned (74) across the web (62) to magnetize the bias elements in a group of markers (20) with a first polarity, thereby activating the group of markers. The web (62) is then advanced (68) and the magnetizer (70) is scanned across the web in an opposite direction (76) to the previous scan to magnetize the bias elements of a second group of the markers (20) with a second polarity, thereby activating the second group of markers. The web (62) is slit in a longitudinal direction to produce web-strips each carrying a column of the activated markers.  The web-strips are rolled to form marker roll assemblies each having about half the bias elements magnetized with a first polarity and the remaining bias elements magnetized with an opposite polarity. The roll of activated markers forms no more than a minimal "leakage"  magnetic field.

Patent CA-2276298-A1 (CA)
Inventor: ILLI THOMAS
IPC: B65G47/18
Filed: 1998-10-02
Abstract: The invention concerns a vibrating conveyor having a circular or helical conveying conduit driven with a vibrating motion by means of an electromagnet with alternating voltage. The conveying conduit emerges, at its end, into an overflow chute produced in the form of a channel switching system (6). The invention is characterised in that an overflow channel (15) is provided oscillating with a reciprocating motion about a pivoting shaft (16). Mechanical and electrical control means (18, 23, 30) are also provided, whereby the overflow channel (15) can be brought, by programmed control, into variable oscillating positions. The overflow channel (15) consists of a Ushaped section, pressing radially on a sliding surface (10) forming a circular zone and fixed on a pivoting shaft (16) mounted on said sliding surface (10). Said section is driven by a reciprocating motion in the peripheral direction of the circular zone, about said pivoting shaft (16). Through the pivoting shaft (16), the section is rigidly connected to a guide rail open downwards (17), arranged beneath the sliding surface (10) and extending parallel thereto. In this rail is housed a cam (21) set on a control disk (18) arranged parallel to the sliding surface (10), such that when the disk is driven in rotation by the electric motor, the cam (21) causes the guide rail (17) to oscillate with a reciprocating motion, and hence the overflow channel (15) above the sliding surface (10).

Patent CA-2280766-A1 (CA)
Inventor: GORDON ROY
IPC: D06P5/08
Filed: 1998-02-18
Abstract: Cellulosic materials are dyed with reactive dye by pretreating the fabric with a polycationic polymeric agent which is desirably also polynucleophilic. The agent can be a polyquaternary amine material especially a poly(DADMAC) or polyvinylpyridine, particularly one including nucleophilic sites such as primary amino groups, e.g. polyallylamine/DADMAC copolymers and polyvinylpyridines quaternsied with .omega.-aminoalkyl groups. The dyes can react with the nucleophilic centres so dyebath exhaustion can be driven by dye fixation rather than substantivity to the substrate. The need to use of salts to drive substantivity can be obviated and post dyeing washing to remove unreacted/hydrolysed dye is much simplified. Material dyed by the method has the good wash fastness properties of materials dyed using reactive dyes. A wide variety of cellulosic substrates can be dyed including lyocell fibre materials and blend/union materials with polyamides.

Title: Method for transmitting data in wireless speech channels
Inventor: RECCHIONE MICHAEL CHARLES
IPC: H04W4/16
Filed: 1999-12-30
Abstract: Non-speech information is sent in the bits allocated to one or both of a vocoder's codebooks' output by setting the gain for the corresponding codebook to zero.  By setting the gain to zero, the codebook output will not be interpreted by the receiving vocoder. In this way, it is possible to transmit additional information in a way that is totally transparent to the vocoder. Applications for this technique of sending "secret" messages include, but is not limited to, transmitting parameters for generating non-speech signals. As an example, information to generate call waiting tones, DTMF, or TTY/TDD characters can be clandestinely embedded in the compressed bit stream so that these non-speech tones can be regenerated.

Title: Control device for an air-fuel ratio sensor
Inventor: AOKI KEIICHIRO
IPC: G01N27/41
Filed: 2000-03-03
Abstract: A control device detects a characteristic change of an air-fuel ratio sensor indicative of deterioration of the air-fuel ratio sensor. The control device determines deterioration due to aging of the air-fuel ratio sensor accurately and calculates an air-fuel ratio from the air-fuel ratio sensor highly accurately. Then, the control device detects a current proportional to the concentration of oxygen in the detected gas from a sensor element by applying a voltage to the sensor element of the air-fuel ratio sensor. By applying AC voltages at high and low frequencies to the element, an AC impedance is detected.      The temperature of the element is controlled to a target temperature according to the high frequency impedance and a characteristic change of the element is detected in accordance with the low frequency impedance.

Title: Processeurs d'autoconfiguration dans un commutateur en mode de transfert asynchrone
Inventor: ENHAGER ULF
IPC: H04L12/56
Filed: 1998-12-15
Abstract: L'invention concerne un noeud d'autoconfiguration qui comprend un certain nombre de processeurs de données associés aux ports correspondants d'un commutateur en mode de transfert asynchrone (ATM). Lorsque le noeud est placé en service, chaque processeur radiodiffuse automatiquement un message initial vers toutes les portes de commutation ATM comprenant chaque identification de processeur et chaque emplacement du port de commutation ATM. Après réception du message initial radiodiffusé par le processeur, un processeur maître désigné enregistre l'identification du processeur de radiodiffusion et l'emplacement du port de commutation ATM dans une base de données et envoie un aperçu dirigé spécifiquement au processeur radiodiffusant le message initial. A partir du signal d'aperçu, le processeur reconnaît l'identité et l'emplacement du commutateur ATM du processeur maître. Des trajets de contrôle interne (ICP) sont établis par le commutateur ATM entre les processeurs utilisant l'identification et les informations sur l'emplacement mémorisées pour chaque processeur de carte. Les trajets de contrôle interne sont utilisés pour communiquer des message de contrôle et d'autres informations entre les processeurs. Ainsi, on obtient une configuration automatique d'un multiprocesseur, un noeud de base de commutateur ATM sans avoir à interroger les processeurs ou à faire intervenir un opérateur humain.
