Title: Compositions and processes for conditioning the surface of formed metal articles
Inventor: AWAD SAMI B
IPC: C10M173/02
Filed: 1993-08-09
Abstract: Surface conditioning is carried out by the use of a composition in the form of an aqueous solution of one or more of the following organic materials, namely ethoxylated phosphate esters, ethoxylated alcohols, ethoxylated fatty acids, ethoxylated hydroxy-substituted fatty acids, and the salts, am ides, ethers and esters of ethoxylated fatty acids and of ethoxylated hydroxy-substituted fatty acids, together with: a biocidal material, such as hydrogen peroxide, in an amount effective to prevent deterioration of the lubricant and surface-conditioner composition during storage or use; and/or an anti-foam agent in sufficient amount to significantly reduce foaming during use. The anti-foam agent may comprise a combination of wax, low-volatility liquid hydrocarbon(s) and high molecular weight fatty acid derivative(s). This composition is used to surface-condition and impart increased mobility to the surface of a previously-formed aluminium article, in which the surface already degreased and cleaned to remove aluminium fines and other solid contamination therefrom, and thereafter water-rinsed, is treated by contacting it with the mobility-enhancing lubricant and surface-conditioner composition.

Title: Permanent magnet hybrid dc motor rotor
Inventor: CHAN CHING CHUEN
IPC: H02K21/04
Filed: 1994-07-04
Abstract: The construction of the claw type rotor consists of male members, female members and permanent magnets. The permanent magnet is mounted between a male member and a female member. The stationary dc field winding is located under the permanent magnet and held by a holder which is mounted on the end brackets. The distinct features and major advantages of the new motors are: (i) the airgap flux can be easily adjusted by controlling the direction and magnitude of dc field current, thus the required volume of permanent magnet is significantly reduced, leading to higher power density; (ii) the efficiencies over the torque-speed range can be optimized through controlling the dc field current; (iii) the speed range can be extended by field weakening; (iv) the motor can operate at constant torque regime and constant power regime; and (v) the construction is simple leading to ease of fabrication. <IMAGE>

Title: Gas sensor monitoring incorporating gas generation
Inventor: PETTINGER KARL-HEINZ
IPC: G01N33/00
Filed: 1995-07-10
Abstract: The sensitivity, response time and the regenerative behaviour of a gas sensor 1 is monitored by producing temporary quantities of gas of the test component and supplying them to the gas sensor. The quantities of gas required for monitoring the sensor are produced electrolytically near the anode and/or at the cathode of generator cell 2 by means of reactions in which water is electrolysed so that local pH displacements occur at the anode and cathode due to production of H<+> and OH<-> and these ions react with compounds such as (NH4)2SO4 and KHCO3 in the electrolyte to produce NH3 or CO2 respectively. Fan 4 supplies the gas to the sensor. The generator cell has separated electrodes and either a gel electrolyte to restrict recombination of H<+> and OH<-> ions or a divider such as an ion exchange membrane between the electrodes. <IMAGE>

Title: .Cylinder liner for a reciprocating piston engine and method of producing such a cylinder liner.
Inventor: RUCKERT FRANZ
IPC: B24B37/02
Filed: 1995-10-03
Abstract: The invention relates to a cylinder liner sealed into a reciprocating piston engine and comprising a strongly supereutectic aluminium/silicon alloy which is free of melt-independent particles of hard material and which is composed in such a way that fine silicon primary crystals 8 and intermetallic phases 9, 10 automatically form from the melt as hard particles. By means of spray compaction, a blank is allowed to grow from finely sprayed melt droplets, with a fine distribution of the hard particles being produced by the setting of small melt droplets. The blank can then be formed by cold extrusion to give a shape approximating the cylinder lining. After subsequent premachining, the face is fine machined, subsequently honed in at least one stage and then the hard particles lying at the face are exposed, forming plateau areas of the particles which project above the remaining surface of the base microstructure of the alloy. The mechanical exposure of the primary crystals or particles is carried out in the manner of a honing process using felt strips 16 which are cylindrically shaped on the outside and a slurry of SiC particles in honing oil.
