Title: Moisture sensor with high sensitivity and detection speed - comprises poly:pyrrole film doped with dodecyl-sulphate anion
Inventor: KIM CHUNG YUP
IPC: G01N27/12
Filed: 1991-07-20
Abstract: High mol. moisture sensor has a polypyrrole film doped with dodecylsulphate (DS) anions. The polypyrrole is permeable for Na and K cations, with salt formation, and has a sensitivity for moisture in the 10 power (4) to 10 power (6) ohm region and detection speed between 10s and 5 mins. The sensor is produced by (a) adding an electrolyte soln. with pyrrole monomers to a soln. contg. DS anions during a polymerisation stage; (b) connecting a fine electrode with sensor structure as positive electrode and a Pt plate as negative electrode; (c) passing d.c., so that a doped polypyrrole film is deposited on the positive electrode and subjecting to a redn. stage in an aq. electrolyte contg. small Na and K cations; and (d) applying d.c. with reversed polarity so that the DS anions are retained in the polypyrrole and the Na and K ions permeate, with salt formation, and impart ion conductivity. The polymerisation electrolyte soln. consists of tetrabutylammonium DS (TBDA) in acetonitrile as aprotic solvent; or an aq. soln. of Na DS. The fine electrode is formed by applying alternating W and Ni films on a glass or Al2O3 base plate; structurising using a positive photoresist; plating with Au in the etched areas; and etching away the positive photoresist, Ni and W to form alternating long and short partial electrodes. Each partial electrode is 16 microns wide, with 5 micron wide gaps between the partial electrodes. ADVANTAGE - The sensor has excellent sensitivity and measuring speed.

Title: Piston head mfg. process - involves using compressed elastic inserts for cooling chamber to reduce heat at combustion chamber edges
Inventor: MARTINS LEITES JOSE MANOEL
IPC: F02B3/06
Filed: 1991-10-18
Abstract: In mfg. a piston head, for high power internal combustion and especially diesel engines, the piston head (1) of a structured piston has a combustion chamber (2), a piston ring zone (3), drillings (4) the gudgeon pins for the lower piston rod linkage, and a cooling chamber (5). The upper section (1) is prepared above the line (55) separating it from the hub section (4). A peripheral groove (10) surrounds the cooling chamber (5) which, at the outermost surface of the upper section (1) is closer to the dividing plane (SS) and in another plane is even closer to the dividing plane (SS). A notch (11) at the outer line of the cooling chamber (5) is at the inner surface of the piston head (1). A peripheral contour groove (15) is at the lower level of the under crown (21). A partially closed unit (6) of an elastic material, pref. in a round shape, matches the outer and inner (D1) dimensions of the coolant chamber (5), close to the dividing line (SS) and with optional clamps and radial edges to form a radial gap at least at a coolant oil channel. The elastic component (6) is compressed, by bringing the edges together to narrow the gap in the ring so that the inner dimensions are smaller than the gap (D) between the outer limits of the chamber (5) near the dividing plane (SS). The compressed part is inserted into the piston head (1) and forced into the chamber for positioning at the groove (10) and notch (11), and the compression on the part (6) is relaxed. A similar elastic partially closed part (13), with an inner contoured edge (14) for oil retention, is compressed for insertion into the groove (15), and then its diametrical compression is relaxed. The upper part (1) of the piston head assembly above the dividng line (SS) is bonded to the gudgeon pin (4) part below the line (SS). ADVANTAGE - The piston gives a good oil cooling action, particularly at the edges and piston ring zones of the combustion chamber.

Patent DE-4142375-A1 (DE)
Inventor: TRATZ HERBERT DIPL ING DR
IPC: F22B1/18
Filed: 1991-12-20
Abstract: Cooling-air cooling units for gas turbines usually have tube plates (4, 7) in which the heat-exchange tubes (5) are mounted so that the air to be cooled is separated from the fluid which takes up the heat.

Title: Recycling of used fats contg. water, esp. from fat-water separators - includes mixing and sedimenting fat, further separating at specific temp. and filtering and vacuum-distilling
Inventor: KRAMASCHKE U DR
IPC: A23K20/158
Filed: 1992-04-14
Abstract: In a procedure for recycling used fats which are mixed with water, the fat is thoroughly mixed, is sedimented to separate it into two phases, and then undergoes a further phase sepn. at a higher temp. before being filtered and vacuum-distilled. The fat may be treated during mixing with a flocculating agent, pref. of a cationic basis. The second stage separation is carried out preferably at about 60 deg. C. The pH during sedimentation and sepn. is kept at about 8, and before the vacuum-distillation it is moved into the acid region. Before the distn., an alkaline hydrolysis of the pre-cleaned fat may if required be performed. The resulting waste water is subjected to a biological clarification. The sludge and residual materials which cannot be put to a biological use are prepared in the normal way for disposal by dumping. USE/ADVANTAGE - For the treatment especially of fats which accumulate in the separators which are required by law to be used for removing fats from waste water before it enters the public drains. These fats are recovered in a manner which protects the quality of the environment.

Title: Treatment of process solns. - with recirculation of detoxicated and cleaned soln.
Inventor: RITUPER RAFAEL DR ING
IPC: C25F7/02
Filed: 1992-06-05
Abstract: The method and apparatus concern treatment of solutions used in electrochemical treatment of metal surfaces, in particular, pickling of stainless steel. Such solutions are treated with acids or alkalis dependent on their pH value. They are treated with detoxification agents dependent on their rH value. Some of the solution is extracted from the process bath (1) - or from an intermediate bath (3) - and is delivered via a pipe (5) into a special reaction vessel (6) for detoxification. The solution containing detoxicated constituents is circulated through a microfilter (11). The filtrate freed from solids is returned to the process via pipes (14 and 21). The solution enriched with solids is extracted from the reaction vessel via a pipe (14) either for direct removal or for further treatment. USE/ADVANTAGE - For electrochemical surface treatment of metals. It allows substances entering into the solution to be recovered in utlisable form, and enables the cleaned solution to be returned to the process.

Title: Press section for web-water extn. during paper-making - has cutter and removal system to trim web ends and remove cut strips from impermeable belt, etc.
Inventor: STEINER KARL DR
IPC: D21F7/00
Filed: 1992-07-04
Abstract: The press section has at least one belt impermeable to water and air to take up the web or to carry it. A unit separates at least one edge zone of the material from the web, such as an edge spray tube or blade, to be removed by at least one system. The edge removal system pref. twists the running plane of the edge strip round two axes, for the edge to travel away to one side, using a scraper and a narrow counter roller, located at a deflection roller which carries the full web width. Pref. the edge strip can also be detached by a narrow pick-up roller with a smooth surface, smoother than the belt surface. A scraper can pref. detach the strip taken by the pick-up roller. The pick-up roller can be conical, and on an axis angled against the belt plane to increase the roller contact surface area. The adjustment for the edge removal with the edge cutter is pref. coupled to a control circuit to maintain a constant required edge strip width. The cutter is linked mechanically to the edge removal. The belt surface is pref. rougher at the edge, to assist removal of the cut web edge strips. A smooth roller can be used instead of a belt, with a suction zone to take off the cut edges of the web. An additional blower can direct the cut edge strips to the pick-up rollers. USE/ADVANTAGE - The appts. detaches the edge zone material from the web, and removes it, to define the web width, to take it from the belt independently of the paper.
