Patent CA-2156466-A1 (CA)
Inventor: WREZEL JAMES ALAN
IPC: B23K35/02
Filed: 1995-08-18
Abstract: Solder pastes presently harden or congeal over time. This results in wasted solder paste and in production down time. This hardening is a result of the long polymer chains created by the dicarboxylic acid in the activator and the indium (In) or tin (Sn). A solder paste is described in which the metal alloy is coated by an agent that inhibits the reaction with the dicarboxylic acid. One solution involves coating the metal alloy powder with monocarboxylic acids, which truncate the polymer chain. Another manner for truncating the polymer is to coat the metal alloy powder with complexing agents. The metal alloy powder can also be coated by a stable metal such as lead (Pb), gold (Au), silver (Ag), bismuth (Bi), palladium (pd), platinum (Pt), a silver palladium alloy (AgPd) or a silver platinum alloy (AgPt).

Title: Process for manufacturing an automotive trim piece having a polymeric skin mounted to a substrate
Inventor: LEE SHUEH-MO
IPC: B29C63/44
Filed: 1994-07-15
Abstract: A process for manufacture of an automotive trim piece having a polymeric skin (18) fastened to a substrate. The polymer, for example, polyvinyl chloride, has the property that upon cooling to a relatively rigid state the polymer shrinks. The process includes molding the polymeric skin separately from the substrate such that the skin has a rear face for abutment with an obverse face of the substrate and a pair of lips (27) extending from ends of the rear face. The lips are configured for engaging corresponding edges (29) of the substrate. The skin is cooled to a relatively elastic state, and the skin and substrate are assembled while the skin is in the relatively elastic state. On further cooling, shrinkage forces of the skin (18) and the skin lips (27) in abutment with the corresponding edges (29) of the substrate produce a snug fit from edge to edge of the skin to the substrate and the skin becomes relatively rigid.

Title: Programmable electronic time delay initiator
Inventor: PRINZ FRANCOIS
IPC: F42B3/12
Filed: 1994-08-01
Abstract: A programmable electronic time delay initiator (10) includes a digital time-delay circuit that counts in response to a dual-resonator clock and, at the end of the programmed time delay, gates the pre-stored charge on a capacitor (32) to a semiconductor bridge initiator (34) to fire an explosive. The timer circuit includes a combined crystal/RC oscillator (44) that provides high accuracy oscillations from the crystal (72) or oscillations from the RC components in the event the crystal fails. The timer circuit functions in response to multi-part serial commands delivered on a conventional two-wire path (L1, L2). The timer is initially powered-on to provide power to a capacitor (28) that supplies power to the time-delay and related circuits. An initial ATTENTION pulse initializes the circuitry and starts a watchdog timer that counts a fixed number of clock cycles and resets the logic if a following WRITE, ARM, or FIRE command is not received. A WRITE pulse and following programming pulses programs a fusible line memory with time-delay information, an ARM pulse effects charging of a firing-charge capacitor, and a FIRE pulse gates the firing-charge to the bridge initiator (34) to fire the explosive.

Title: Latent mercaptans as multi-functional additives for halogen-containing polymer compositions
Inventor: DUVALL TOD C
IPC: C08G8/28
Filed: 1996-04-25
Abstract: Halogen-containing polymer compositions comprising a latent mercaptan-containing   heat   stabilizer   composition   are substantially free from the offensive odor typically associated with  mercaptans  are  protected  during  processing  by  the degradation products of the latent (i.e., blocked) mercaptan which  include  a  free  mercaptan.    Other  products  of  the degradation are believed to include carbocations of the blocking moiety which are stabilized by a molecular structure in which the electron deficiency is shared by several groups. The latent mercaptan may be the sole heat stabilizer additive but the free mercaptan released during processing may also synergize the activity of metal-based heat stabilizers such as metal salts and organometallic stabilizers such as organotin carboxylates and mercaptides in the polymer composition.  The latent mercaptans also serve as intermediates in the preparation of anti-oxidants, anti-microbial  agents,  photostabilizers,  and  primary  heat stabilizers. Highly effective heat stabilizers are prepared by the condensation of formaldehyde and a para-phenol and further condensation of the crude product with a mercapto-containing compound.

Title: Methods for modulating t cell responses by manipulating intracellular signal transduction
Inventor: JUNE CARL H
IPC: A61K31/365
Filed: 1995-05-01
Abstract: Methods for modulating T cell responses by manipulating intracellular signals associated with T cell costimulation are disclosed. The methods involve inhibiting or stimulating the production of at least one D3-phosphoinositide in a T cell. Production of D3-phosphoinositides can be manipulated by contacting a T cell with an inhibitor or activator of phosphatidylinositol 3-kinase. Inhibitors of phosphatidylinositol 3-kinase for use in the methods of the invention include wortmannin and quercetin, or derivatives or analogues thereof. The methods of the invention can further comprise modulating other intracellular signals associated with costimulation, such as protein tyrosine phosphorylation, for example by modulating the activity of a protein tyrosine kinase or a protein tyrosine phosphatase in the T cell. Inhibition of a T cell response in accordance with the disclosed methods is useful therapeutically in situations where it is desirable to inhibit an immune response to an antigen(s), for example in organ or bone marrow transplantation and autoimmune diseases. Alternatively, stimulation of a T cell response in accordance with the disclosed methods is useful therapeutically to enhance an immune response to an antigen(s), for example to stimulate an anti-tumor response in a subject with a tumor, to stimulate a response against a pathogenic agent or increase the efficacy of vaccination. Novel screening assays for identifying inhibitors or activators of phosphatidylinositol 3-kinase, which can be used to inhibit or stimulate a T cell response, are also disclosed.
