Patent CA-2050378-A1 (CA)
Inventor: DAHRINGER D W
IPC: H01L23/433
Filed: 1991-08-30
Abstract: The present invention is an electronic circuit, such as a Hybrid Integrated Circuit (HIC), having an element mounted on a suitable support base, and a self-adjusting heat sink mounted on the element. A heat spreader is located inspaced relationship with the support base. The heat spreader may be a plate of conductive material provided especially or may form a part of a housing enclosing the HIC. The heat sink has a bottom portion secured to the element and at least one flange for conducting heat energy to the heat spreader. Each flange includes an upright segment projecting from the bottom portion of the heat sink toward the heat spreader, a free end segment bent away from the heat spreader and a knee-bend segment intermediate the upright segment and the free-end segment and adjacent to the heat spreader. Each flange is also provided with a thermally responsive section, hereinafter referred to as "thermostat", which forms a part of the upright segment and in response to the presence or absence of a certain amount of heat energy causesmovement of the free end segment of the heat sink, respectively, toward or away from the heat spreader so as to establish a greater or lesser area of contact with the heat spreader. This thermostat is formable in several ways including inlaying into an upright segment of the flange a metal with a coefficient of thermal expansion different from that of the flange or by attaching such a metal to the upright segment.

Title: Method and apparatus for dispensing high viscosity fluid materials
Inventor: PORTER GEORGE O
IPC: B05C5/02
Filed: 1992-03-27
Abstract: A method and apparatus for dispensing a solution of highly viscous polymeric material and gas includes a dispenser connected to a pressure regulator which is adapted to connect to a source of a pressurized polymer/gas solution. Minimal pressure drop due to line losses occurs in the course of transmitting the solution from the pressure regulator into the dispenser because of their close proximity, and the solution is maintained under controlled pressure throughout passage to the discharge outlet of a nozzle carried by the dispenser so that the gas is maintained in solution in the polymeric material until it is discharged from the nozzle to atmosphere. The flow rate of solution through the dispenser is variable by operation of adjustable valve structure associated with the dispenser and/or by operation of the pressure regulator.

Abstract: 31,660-00 METHOD OF TREATING OR PREVENTING MASTITIS IN ANIMALS      WITH INVOLUTING MAMMARY GLANDS BY ADMINISTERING           RECOMBINANT CYTOKINES               ABSTRACT OF THE INVENTION Cytokines  are  useful  for  the  ability  to improve the natural defense system of the involuting mammary gland. In addition to the immunopotentiating activity, cytokines accelerate the normal physiology of involution of the mammary  gland and  thereby  afford further protection against new infections of mammals. The involuting mammary gland is very susceptible to infection during the early stages of  involution and therefore decreasing the period of highest suscepti-bility  while  also  improving  the  natural  defense mechanisms is of great advantage over most therapies. Used alone,  in various cytokine combinations,  or in combination with other therapeutics, cytokines protect the mammary gland and cure existing infections and are particularly useful during cessation of lactation and early reinitiating of lactation.
