A method of preventing the yellowing of the outermost coating of a multicoat coating system is disclosed. The method comprises initially depositing onto a conductive substrate by cathodic electrodeposition a primer coating comprising at least one layer of an amine-epoxy resin adduct and a cross-linking agent, and then curing said primer to a hard, durable film. Then, depositing a second coating on...

A method of making a lead-acid battery includes providing continuous lengths of end separator stock, positive plate stock, intermediate separator stock and negative plate stock with optional use of end separtaors. The separators, positive plates and negative plates are individually severed from the continuous length of stock and sequentially formed into an assembly. The assembly is introduced into...

The invention relates to a method and an apparatus for aliasing quantization. The apparatus comprises a quantization means (3) for the quantization of a difference signal (e(n)) between an input signal (x(n)) and a prediction signal (p(n)), a prediction means (5) for providing the prediction signal depending on the summed signal of a quantized difference signal (e'(n)) and the prediction signal (p...

A microwave cooking bag, method, and system are disclosed in which a food product in the bag is cooked, browned and crisped in a microwave oven. The bag forms an enclosed cooking space which is substantially surrounded by a susceptor material layer. The susceptor material layer is heated during cooking by the microwave radiation to a temperature sufficient to brown and crisp the food product while...

The invention refers to a metallic insert wherein the thread is a fine saw tooth-shaped thread, the receiving bore in the work-piece has the same tapering angle as the insert, the diameter of the receiving bore relative to the diameter of the insert as well as the pitch and the thread depth are selected such that the spaces between the threads are filled out at least almost totally when the insert...

A toy life sounds monitor is provided having a housing containing an energy source means supplying energy to a first transducer means and amplification means for driving a second transducer means. The housing is structured and dimensioned in a form appealing to small children and for application to the abdominal area of a pregnant woman for purpose of monitoring intrauterine life sounds in the pre...

A water softening system is provided including a service step, a regenerating step and a rinse step. The service step includes introducing relatively hard water into the inlet, through an ion exchange resin and out the outlet to a service location. The regenerating step includes introducing a brine solution into the inlet, through the resin and out the outlet to drain. Prior to the service step, a...

Blends of water soluble polymers containing varying ratios of acrylamide and sodium 2-acrylamido-2-methylpropane sulfonate are provided which synergistically increase the viscosity of acidic solutions. Improved methods of matrix acidizing and fracture acidizing are also provided.

An MOS transistor for use in an integrated circuit, particularly CMOS integrated circuits, is fabricated with a self-aligning contact and interconnect structure which allows for higher packing density. Self-aligning source and drain contacts overlap the gate but are prevented from a short circuiting to the gate by oxide insulation between the source/drain contacts and the gate, and a layer of sili...
