Patent number: 5550054Abstract: Novel hematopoietic-restricted tyrosine kinases are provided, where the tyrosine kinases provide for autophosphorylation and transphosphorylation. Modulation of the activity of the subject compositions can be used to restrict growth and differentiation, to correct genetic deficiencies, and to elucidate the activation pathway involved with the subject tyrosine kinases. In addition, the tyrosine kinases may be used in a variety of assays as a label or in the production of the phosphorylated peptides.Type: GrantFiled: February 21, 1995Date of Patent: August 27, 1996Assignee: The Regents of the University of CaliforniaInventors: Owen Witte, Satoshi Tsukada, Douglas Saffran, David Rawlings

Patent number: 5409472Abstract: A conformable wound dressing is produced which comprises a polymeric foam absorbent layer, a continuous or discontinuous adhesive layer covering the body facing surface of the absorbent layer except for a wound contacting area which is free of adhesive and a layer of a liquid impervious moisture vapor permeable material disposed over substantially all or the entire surface of the absorbent layer opposite the body facing surface. The wound dressing may have a discontinuous intermediate layer coextensive with the absorbent layer disposed between the absorbent layer and the adhesive layer. Preferably, more than 50% of the absorbent layer is free of adhesive or when the adhesive is placed on the intermediate layer, more than 50% of the absorbent layer and the intermediate layer are free of adhesive.Type: GrantFiled: April 5, 1993Date of Patent: April 25, 1995Assignee: Smith & Nephew plcInventors: David A.

Patent number: 5385542Abstract: A tampon applicator has an outer cylindrical member for containing a tampon and an inner arcuate member which is arranged to lie between the inner surface of the outer member and the tampon and to be slidably moved within the outer member to act as a piston for ejecting the tampon. One end of the inner member is adapted to engage the tampon and has a shoulder region. The outer member is provided with a first inward projection to engage the tampon and prevent rearward movement thereof and at least one second inward projection intermediate the first projection and the rear end of she cylindrical member to engage the shoulder region of the inner member and prevent complete withdrawal of she inner member from the outer member. The inward projections comprises at least one flap for example a pair of flaps or an inwardly deformed arcuate strip.Type: GrantFiled: September 3, 1993Date of Patent: January 31, 1995Assignee: Smith & Nephew plcInventor: David A. Rawlings

Patent number: 5010883Abstract: An adhesive dressing for use on moist wounds which comprises a pressure sensitive adhesive-coated wound contacting first layer in which there are present holes capable of transmitting liquid water and a moisture vapor permeable, continuous film. The continuous film is attached to the first layer in such a way as to form a reservoir into which water can pass through the holes in the first layer and can evaporate from the reservoir through the continuous film. The adhesive coated first layer has a moisture vapor permeability of less than 300 gm.sup.-2 24 hr.sup.-1 at 37.degree. C. and 100% to 10% relative humidity difference and the continuous film has a moisture vapor permeability which is greater when in contact with liquid water than when not in contact with liquid water. Optionally, an intermediate water transmitting layer may be present between the first layer and the continuous film.Type: GrantFiled: May 8, 1989Date of Patent: April 30, 1991Assignee: Smith & Nephew Associated Companies plcInventors: David A. Rawlings, William D. Potter

Patent number: 4798201Abstract: A surgical dressing is described which consists essentially of a film which carries an adhesive layer for securing the dressing to the body characterized in that (a) the film is continuous and comprises a polymer which in contact with water has a higher MVP than when in contact with moisture vapor but not water; (b) the adhesive layer is adapted to allow access of water to the film when water is in contact with the adhesive layer so that (c) the surgical dressing has an MVP of not less than 2500 g/m.sup.2 when the adhesive layer is in contact with water and has an MVP of not more than 2000 g/m.sup.2 when the adhesive is in contact with moisture vapor but not water; whereby the dressing is suitable for use on exuding wounds and on non-exuding wounds.Type: GrantFiled: December 30, 1986Date of Patent: January 17, 1989Assignee: Smith and Nephew Associated Companies p.l.c.Inventors: David A. Rawlings, William D. Potter

Patent number: 4747401Abstract: A surgical dressing which consists essentially of a film which carries an adhesive layer for securing the dressing to the body characterized in that (a) the film is continuous and comprises a polymer which in contact with water has a higher MVP than when in contact with moisture vapor but not water, (b) the adhesive layer is adapted to allow access of water to the film when water is in contact with the adhesive layer so that said surgical dressing has a MVP of not less than 2500 g/m.sup.2 when the adhesive layer is in contact with water and has a MVP of not more than 2000 g/m.sup.2 when the adhesive is in contact with moisture vapor but not water; whereby the dressing is suitable for use on exuding wounds and on non-exuding wounds.Type: GrantFiled: November 3, 1986Date of Patent: May 31, 1988Assignee: Smith and Nephew Associated Companies p.l.c.Inventors: William D. Potter, David A. Rawlings

Patent number: 4657006Abstract: A moisture vapor permeable, adhesive surgical dressing is described which comprises a continuous film of a hydrophilic polymer which has a moisture vapor permeability which is greater when in contact with water than when not in contact with water and which is attached around its edges to a water transmitting film so as to form a sealed portion into which exudate may pass from an exuding wound. The water transmitting film comprises a backing layer and an adhesive layer on the side remote from the continuous film. The adhesive layer is suitable for adhering the dressing to the skin. The water transmitting film allows or is adapted to allow access of water to the film when in contact with water so that when used on an exuding wound the high moisture vapor permeability of the continuous film allows water to evaporate through the dressing and prevents the dressing forming a blister.Type: GrantFiled: June 13, 1986Date of Patent: April 14, 1987Assignee: Smith and Nephew Associated Companies p.l.c.Inventors: David A. Rawlings, William D. Potter

Patent number: 4410773Abstract: A rotary type switch for switching a relatively large plurality of independent circuits from one set of contact to a second set of contacts for manual or remote operation using a solenoid or linear actuator. The switch utilizes as contacts a simple wire form cantilevered for compliance at one end, and free to move vertically at an opposite end. A plurality of bridging contacts, properly sized and plated shorts adjacent pairs of wires together when the contacts move in an arcuate path or motion, causing the wires in the path to deflect, and causing the contacts to bridge pairs of adjacent wires to complete a circuit between them. Insulative members are positioned adjacent the gaps between the bridging contacts to limit the degree of flexing of the wires during movement of the bridging contacts.Type: GrantFiled: October 9, 1981Date of Patent: October 18, 1983Assignee: Porsa Systems Corp.Inventors: Paul V. De Luca, David Rawlings

Patent number: 4313039Abstract: A modular telephone distributing frame particularly suited for rapid installation. The frame includes a plurality of framework groups that are mounted end to end in one or more lines to construct a frame of desired ultimate capacity. Each framework group consists of three separate assemblies, including a protector frame assembly for terminating outside cable pairs, a line equipment frame assembly for terminating line equipment and associated equipment appearances, and a vertical channel assembly used to connect the protector frame assembly and the line equipment frame assembly. Connector blocks and terminal blocks are prewired together, and are installed on the frame by passing one of the blocks through from one side to the other prior to mounting on the opposite side of the frame.Type: GrantFiled: May 19, 1980Date of Patent: January 26, 1982Assignee: Porta Systems Corp.Inventors: Paul V.
