Title: Composite particle dispersions
Inventor: WATERS JULIAN ALFRED
IPC: C08J3/00
Filed: 1989-01-06
Abstract: A process for the preparation of composite particle dispersions is disclosed. The composite particles have a core particle 1 surrounded by a second material 2. Normally a core shell particle will be formed and the second material which forms the shell will be a polymer material. 
     The composite particles are formed by mixing a dispersion of polymer particles with pre-formed core material particles. The polymer particles are stabilised relative to one another, and the core material particles are destabilised in the dispersion so that they are able to make contact with the surfaces of the polymer particles. The process takes place at a temperature above the operative glass transition temperature of the polymer, and in the process the polymer spreads over the surface of the core particle so that the core particle is encapsulated. 
     The process will proceed, and composite particles will be formed, when the interfacial energies of the three interfaces (core/polymer: core/liquid: polymer/liquid) and the relative volumes of the core particles and polymer particles are related to one another in accordance with an equation which is set out in the specification.

Abstract: In a communication method for a single-wire databus for motor vehicles comprising a central station and peripheral units containing sensors, in which the central station sequentially addresses the peripheral units by means of voltage pulses and the peripheral units deliver a current signal to the databus, the peripheral units, in their transmitting operation, first deliver their address as a coded current signal and then a coded current information covering the entire range of values of the sensor at the same reference voltage as the address current signal to the databus and thus to the central station. This makes it possible to identify the peripheral unit transmitting in each case and, at the same time, to detect the various variable sensor values in a bi-directional data traffic on a single-wire databus.

Abstract: The invention relates to a process for the production of polyurethaneurea elastomer filaments and films which are resistant to light and to polluting gases and are based on segmented polyurethaneureas, based on diisocyanate mixtures of 30 to 85 mol % trans-1,4-cylcohexylene diisocyanate and 17 to 15 mol % of further aliphatic or cycloaliphatic diisocyanates. The diisocyanates are reacted with relatively high molecular weight dihydroxy compounds and optionally low molecular weight diols, initially to give an NCO prepolymer, and then with aliphatic diamines or diamine mixtures, preferably ethylenediamine, in highly polar solvents, optionally in the presence of salt-like solvents, such as lithium salts, and preferably with the concomitant use of aliphatic chain terminators, in particular those having a cycloaliphatic structure, to give elastomer solutions which are stable to processing. These solutions are spun in a conventional manner and dried to give films or coagulated to give sheets. 
<??>The invention also relates to the segmented polyurethaneurea elastomers, in particular filaments, obtained by the novel process.

Abstract: This switch-on current limiter limits the excess switch-on current occurring when switching on a load, for example a transformer (8) for supplying a low-voltage halogen lamp (9), it being possible for the switching on to take place universally via a switch (100), via a dimmer (7) without the mains phase connected, or via a dimmer (10) with the mains phase connected. To limit the current, a resistor stage (1) is connected in series with the load. After a delay time has elapsed, a switching stage (3) bridges the resistor stage (1). The switching stage (3) is driven with the aid of a mains power supply (2). A signal conditioning stage (4) receives the load voltage on the input side, forms a delay time and drives the mains power supply (2) via a switching amplifier. When the switch-on current limiter is in use on a switch (100) or a dimmer (10) with the mains phase connected, the delay time is generated by the mains power supply (2) itself. <IMAGE>

Title: Enhanced ocean bottom sonar system
Inventor: EARP RONALD LEE
IPC: G02B6/50
Filed: 1990-11-22
Abstract: The invention provides apparatus and method for causing buried ocean cable (5) to emit distinct characteristic "signature" backscatter signals when a suitable sonar signal is played onto the cable. The "signature" signals are distinct for specific individual constructions of cable, and therefore assist in determining the identity of a buried object without having to dig it up. Search apparatus (3) launches the unique sonar signal toward the buried cable, with a predetermined beamwidth, attack angle, cross-section, and signal character. The signal consists of a succession of bursts of different frequencies, separated by a step function, for example, and separated by silent periods. The signal is repeated as the search vehicle travels a predetermined direction with respect to the estimated cable orientation. The backscatter signals are received by the sonar apparatus (4) for analysis by digital comparison to a data library of known signal patterns, or for display on an operator's monitor.
