Patent GB-2041488-A (GB)
Title: Elastomeric mountings with fluid damping of low frequency high amplitude movements
IPC: F16F13/10
Filed: 1979-08-31
Abstract: A damping support for suspending a body on a supporting structure comprises a tubular mounting body 10 for fixing to the supporting structure, an attaching body 18 for fixing to the body, and connected between them an annular, elastomeric element 20. A resilient membrane 38 defines, together with the annular elastomeric element 20, a chamber internally of the tubular mounting body 10 filled with a fluid. A transverse separator 52 subdivides the chamber into two secondary chambers 76, 78 and comprises a rigid peripheral portion 54 which is deflectable to an extent limited by arresting means 68, 70, and has an aperture 66. If used to mount a vehicle engine, high frequency low amplitude movements of the engine are not fluid damped, changes in volume in the chamber being accommodated by deflection of the separator, but low frequency high amplitude movements from the suspension are damped by flow through the aperture. <IMAGE>

Title: Carboxylic Solubilizer/ Surfactant Combinations and Aqueous Compositions Containing Same
IPC: C08F8/14
Filed: 1979-09-26
Abstract: Combinations of (A) carboxylic solubilizers, made by reaction of a carboxylic acid acylating agent having a C12-500 hydrocarbyl based substituent with an N-(hydroxyl- substituted hydrocarbyl) amine and/or hydroxyl-substituted poly(hydrocarbyloxy) analog of the amine and (B) surfactants are useful in incorporating oil-soluble, water- insoluble functional additives into aqueous systems. Typical solubilizers are made by reacting an alkyl- substituted succinic anhydride containing C12-500 with an alkanol amine e.g. diethyl ethanol amine. Typical surfactants are non-ionic hydrophilic surfactants e.g. ethoxylated phenols. Typical functional additives are anti-wear, extreme pressure and load-carrying agents e.g. dithiophosphates. The aqueous systems formed with the aid of such combinations are useful, e.g., as water-based hydraulic fluids.

Title: Ebulliometric hot spot detector
Inventor: HANCOCK ROBERT D
IPC: F16J3/04
Filed: 1982-11-23
Abstract: An ebulliometric hot spot detector detects hot spots with a resolution of the order of a micron on semiconductor devices. The device to be tested is operated in a suitable liquid contained in the detector, and the liquid pressure is decreased until boiling from sites on the device is observed. The liquid pressure is then increased until boiling ceases; meanwhile, the boiling sites on the device are observed. Small bubbles observed just before cessation of boiling pinpoint the hot spot locations. The pressure at which boiling ceases in a given liquid determines the hot spot temperature.
