Aqueous dispersions of water-insoluble polymers employ fatty acid salts as plasticizers/stabilizers. These dispersions may be coagulated by adjusting the pH until the fatty acid salts are converted to free acid form.

A method and apparatus is disclosed for electrically measuring the inside diameter of a metallic pipe such as oil or gas well casing. The transimpedance of two coaxial coils within the pipe is determined and then resolved into its inphase and quadrature components. The magnitudes of these two components are used to generate a corrected measurement output. A signal representative of the inside diam...

Polyurethane foams prepared from the reaction of polyester polyol with organic isocyanate have improved flame retardance and dripping ember retardance by incorporation of an additive comprising (1) halogenated flame retardant, and (2) water or alcohol soluble urea-formaldehyde resin.

Security strips containing magnetizable components, which are used, for example, to safeguard articles in stores, are manufactured by first applying to a continuous carrier band (11) which is moved progressively in fixed cycles and which has a double-sided adhesive film (11 min ), strip sections or elements (13 min ) of a hard magnetic material which are spaced equally and which are fed from suppl...

PURPOSE:To continue reproduction information after a temporary stop by comparing a frame reproduced from a disk with a frame set optionally through a pickup means and executing a track jump in accordance with the result of comparison. CONSTITUTION:The position index signal is detected by a detecting circuit 5 among those signals read out by a pickup means 1 and then supplied to a comparator 6 in t...

In a device for gassing liquids or suspensions, a first guide means is located at a short distance, opposite the orifice of a jet pipe. This guide means is supported via a gas inlet on a second guide means. The first guide means provided can be a cone and the second guide means can be a truncated cone which merges into a disc-shaped annular zone.

A system (10) for determining the level of a fluidised bed uses a minimum number of pressure sensors. A pressure sensor (12) is positioned at the base of the bed, another pressure sensor (14) is positioned at approximately 2.44 m (8 ft) above a distributor plate, and other pressure sensors (16, 18) are positioned at intermediate locations therebetween. The measurements from the sensors are selecti...

By the use of the method a service channel with a narrow bandwidth is transmitted over a conductor in a fibre- optic system by the utilization of the frequency range close to f = 0. In the system normal data signals are transmitted at a certain high frequency (34 Mbit/s), which signals are coded in accordance with a particular code signature. The output spectrum of the code is greatly suppressed a...
