Title: Method and apparatus for analog-to-digital conversion
Inventor: MAYFIELD GLENN A
IPC: H03M1/12
Filed: 2001-09-11
Abstract: A method and apparatus for analog-to-digital (A/D) converting an input signal having a first polarity include providing an integrator including a capacitance coupled to an input port of an amplifier, coupling an A/D converter to an output port of the amplifier, changing the amount of charge stored in the capacitance by coupling the input signal and a reference source having a second and opposite polarity to the capacitance, and controlling an A/D conversion cycle of the A/D converter to simultaneously charge and discharge the capacitance with the input signal and the reference source prior to each A/D conversion cycle. Another method and apparatus for (A/D) converting an input signal include providing an integrator including a capacitance coupled to an input port of an amplifier, coupling an A/D converter to an output port of the amplifier, changing the amount of charge stored in the capacitance at a known time rate by alternately coupling the input signal and a reference source to the capacitance through at least one switch, and controlling an A/D conversion cycle of the A/D converter and the at least one switch for controlling the coupling of the input signal and the reference source to the capacitance.

Title: Antagonistes d'anticorps monoclonaux diriges contre des facteurs de croissance hematopoietiques
Inventor: LOPEZ ANGEL F
IPC: C07K16/28
Filed: 1996-12-24
Abstract: Cette invention concerne un anticorps monoclonal (MoAb) dirigé contre la chaîne alpha du récepteur d'IL-3, lequel anticorps est le produit d'une lignée de cellules hybridomes appelée 7G3. Cet MoAb agit en qualité d'antagoniste de l'activité de l'IL-3 in vitro. Le MoAb se lie à la région de l'extrémité N-terminale de la chaîne alpha du récepteur de IL-3 et le fait en compétition avec l'IL-3, ce qui indique une participation, en partie du moins, à la liaison de l'Il-3. Les traitements effectués à l'aide du MoAb ou de l'un de ses fragments, recombinés ou autres, peuvent être utilisés dans des cas tels que la leucémie myéloïde, les lymphomes tels que les lymphomes B folliculaires, ou encore pour le soulagement d'allergies.

IPC: E21B17/10
Filed: 2002-06-13
Abstract: L'invention concerne un outil constitué d'une bande d'usure (105) sertissable destinée à être installée sur un tubage (6), utilisé dans un forage de puits. Cet outil constitué d'une bande d'usure (105) consiste en un corps cylindrique qui lorsqu'il est placé de manière coaxiale sur un tuyau, puis sensiblement déplacé vers l'intérieur de manière radiale au niveau de plusieurs points (à savoir serti) autour de la circonférence d'une section du corps cylindrique, se fixe au tuyau afin de créer une connexion présentant une capacité de transfert de charge de pivotement et de charge axiale importante sur le plan structurel. Lorsqu'il est serti selon les procédés de cette invention, la capacité de transfert de charge de la connexion entre l'outil constitué de la bande d'usure (105) et le tuyau (106) peut être arrangée de manière à sensiblement empêcher un mouvement relatif important de l'outil constitué de la bande d'usure sur le tuyau soumis à des charges pouvant être rencontrées lors de l'utilisation d'un ou plusieurs tuyaux en tant que composants d'un train de tiges tubulaire utilisé en vue de forer ou de traverser le tubage afin d'achever un puits.

Patent CA-2000350-A1 (CA)
Inventor: BELIN FELIX
IPC: F23J15/02
Filed: 1989-10-10
Abstract: ABSTRACT OF THE INVENTION This invention pertains to a discharge restrictor secured to the lower end region of impingement members installed in the flue gas path of a circulating fluidized bed boiler. The discharge restrictor incorporates a pivotable baffle plate that prevents the flue gas from bypassing the impingement members yet allows the particles that are collected to gather in an adjacent storage hopper. The baffle plate is normally biased to block access to the storage hopper until a sufficient mass of particles collect on the baffle plate thereby overcoming this bias. In doing so, the plate temporarily pivots to the open position enabling the particles to advance towards the storage hopper.

Patent CA-2003793-A1 (CA)
Inventor: SHELLENBERGER TIMOTHY J
IPC: F24H9/00
Filed: 1989-11-24
Abstract: ABSTRACT         To inhibit internal heat exchanger corrosion, the pro-ducts of combustion from a standing pilot flame in an induced draft,  fuel-fired furnace are prevented from migrating through the heat exchanger during idle  periods of the furnace by flowing the products of combustion upwardly through a small vent tube into the outlet section of the draft inducer fan, and then into an external exhaust stack, thereby bypassing the heat exchanger.          During operation of the draft inducer fan a negative pressure is maintained  within  the  vent  tube,  to  prevent  combustion  gas outflow therethough which might otherwise snuff out the pilot flame, by a venturi structure positioned within the draft inducer fan outlet section adjacent its juncture with the vent tube.

Title: Compressable cheese center for dyeing purposes
Inventor: WINDHOSEL RALF
IPC: D06B23/04
Filed: 1989-12-18
Abstract: (new) A b s t r a c t This invention relates to a compressible cheese centre for dyeing purposes, comprising two end rings and a plural-ity of intermediate stiffening rings (12, 14 and 16) connected together by springy webs (18).          Belonging to the state of the art is a cheese centre (US 3 753 534) in which the webs are bent at rightangles and joined at rightangles to the rings and all the webs and stiffening rings form a cylindrical envelope on their external surface. There has also been disclosed (DE 75 16 449, Figs.5  and 6) a cheese centre having spacer lugs cooperating pairwise situated between the rings which are connected together by S-shaped webs whose middle sections can be clamped between the pairs of lugs.          A disadvantage of the first cheese centre is that textile fibres or threads wound on to the centre for dyeing purposes are liable to be clamped between the webs and rings of the centre  when the latter is under axial compression and are thereby liable to be damaged.          It is an object of the present invention to protect the textile material when the cheese centre is under compression.          The solution to this problem is provided by spacer lugs (34) arranged pairwise between webs (18) which are adjacent to one another in the circumferential direction of the cheese centre so that the lugs (34) of each pair meet when they  approach one another in the axial  direction.          The advantage of this solution is that it prevents parts of the web from abutting against the adjacent ring when compression is too high. Such  abutment could cause breakage of the web as well as clamping of the fibres or threads.          Fig.1 is the main figure.
