Such a halogenated copolycarbonate is characterized in that it (a) has a Phenolic End Group content of less than 275 ppm, (b) has a content of less than 90 ppm of the element of Process Chemical End Groups which is bonded to a copolycarbonate chain end, and (c) produces less than 0.5 absorbance units, per mole fraction of halogenated diphenol in the copolycarbonate, when measured on a spectrophotometer at 420 nm after the halogenated copolycarbonate has been heated for thirty minutes at 300°C and then dissolved in an organic solvent.     37,956-F
Patent CA-2037941-A1 (CA)
Inventor: SHEU SHEN S
IPC: C23C30/00
Filed: 1991-03-11
Abstract: A method of rolling metal in a plurality of rolling stands with each of the stands having two or more rolls.  The method includes first polishing the surfaces of the rolls to an average roughness of less than 0.3 microns, after which the roll surfaces are textured with a plurality of minute micron size craters.  The roll surface and craters are then coated with a dense, hard material before the rolls are lubricated and used to reduce the thickness of the metal in the stands.  To this end, the metal is directed through the stands, the craters being capable of retaining and carrying lubricant into the bites of the rolls without substantial adherence of metal to the roll surfaces and without substantial generation of wear debris on the surfaces of the rolls and rolled material.

IPC: C08K13/02
Filed: 1991-09-26
Abstract: Disclosed is an intumescent curable composition which contains as a resinous binder a flexible polyepoxide resin. The polyepoxide is cured with an appropriate curing agent adapted for the particular resin. An additive component is present which contains a mixture of materials which provide a source of     (i) zinc,   (ii) boron,   (iii) phosphorus, and (iv) an expansion gas upon thermal decomposition. The composition is capable of forming a carbonaceous char upon exposure to heat or flame, with the proviso that the cured, unburned composition has sufficient flexibility that it passes at least 10 continuous cycles of a cold cycle test without cracking. The cold cycle test involves the following steps: the composition is applied at a thickness of 0.5 inch (12.7 millimeters) to a 10 inch (0.254 meter) section of a 4W13 I-beam having two thermocouples attached to the surface, allowed to cure at ambient temperature for 16 hours, force cured for 5 days at about 60 DEG C and subjected to the cold cycle test. For one cycle, the beam is placed in a freezer operating at a temperature between about 0 DEG F (-18 DEG C) and about -10 DEG F (-23 DEG C) for sufficient time for the steel to reach a temperature between about 0 DEG F (-18 DEG C) and about (-10 DEG F) -23 DEG C as determined by the two thermocouples attached to the surface of the beam beneath the coating, removed from the freezer and a 50 square inch area (0.0323 square meter) of the surface warmed as shown in FIGS 1 and 2 by passing a heat gun (Model No. HG 50146, Alpha Division of Loral Corp, 14 amp: minimum temperature at tip 500 DEG F (260 DEG C)) a distance of 0.5 inch (12.7 millimeter) from the surface, uniformly over the surface until the surface temperature reaches 110 DEG F (43 DEG C) within a 3 minute period, as determined by a thermocouple moved about the surface and allowed to stand for at least 2 hours at ambient temperature.   <IMAGE>

Title: Sonar array mounting for sonobuoy
Inventor: BUCKINGHAM DAVID E J
IPC: G10K11/00
Filed: 1991-03-15
Abstract: A sonobuoy comprises a sonar array mounted on arms (2) that are pivotally connected to a central support (3) and housed by an outer housing (1). Upon entry of the sonobuoy into water a float (8) is deployed which since it is connected to the central support (3) by a line arrests the downward motion of the central support (3). The outer housing (1), by virtue of its inertia, travels on uncovering the arms (2) and positively locating the arms (2) by pulling on lines (17) connected to the arms (2). The use of the motion of the housing (1) to deploy the arms (2) eliminates the requirement for spring powered motors reducing the cost of the sonobuoy.
