IPC: C09D5/24
Filed: 1980-04-25
Abstract: An antistatic coating composition useful in forming conductive layers comprises a conductive, waterdispersible, particulate polymer and a crosslinkable latex binder. The crosslinkable latex has a first glass transition temperature before crosslinking less than 50°C and a second glass transition temperature after crosslinking an coalescing greater then 50°C wherein the first and second glass transition temperatures differ by at least 4°C. The coating composition can be coated on a variety of supports to produce conductive elements. The coating compositions are particularly useful in forming photographic elements which are resistant to the buildup of static charge and ferrotyping.

Abstract: This invention relates to articles at least a portion of a surface of which includes an electroplated gold coating having a Knoop hardness number of at least 100 and a process of producing the same. The coating, which may be called "Additive-Free Hard Gold", consists of gold with additional metal ingredients in the deposit, especially such hardening nonnoble metals as Co, Ni, Ca and As, being not greater than 0.1 weight percent and the smoothness of the coating over at least 95 percent of a major surface does not deviate from flat by more than 0.5µm within a sampling area of 5µm square. The gold deposit is produced by electroplating with a fluid which contains gold and cyanide; the electroplating conditions are selected such thatthe pH of the fluid is 7.5 or less, the content of hardening nonnoble metals, if present, in the fluid is in an amount of no more than 0.5 percent of the gold content. the temperature of the fluid in the vicinity of the surface is no greater than 50°C, the flow rate of the fluid in the vicinity of the surface is at least 50 cm/sec and the current flow resulting from maintaining the surface cathodic relative to an anode is at a maximum value not greater than 0.9i  where is defined as the mass transport limited current which is the current beyond which further increase results in no further increase in gold plating rate. The resulting "Additive-Free Hard Gold" is suitable for use in electrical switch contacts and other devices, as well as in ornamentation, requiring hardness and wear characteristics generally associated with so-called "hard gold".

Abstract: The stack (16) includes an inner shell (46) defining a passage (50) to carry the exhaust gases without essentially restricting the draft. Surrounding this shell in any desired configuration is tubing (56,58) carrying fluids (liquids, gas or oils). Surrounding the tubing is an intermediate shell (62), insulation (64) and an outer shell (66). During the passage of the fluid through the tubing, transfer of heat occurs from the gases to the fluid so that its temperature is elevated for use, e.g. as hot water, thus elminating or supplementing a hot water heater. Other uses requiring elevation of the temperature of water or gas may be similarly utilized.

Abstract: The invention relates to a device for adjusting rotatable diffusor guide vanes 4, 5, arranged in the form of a ring, of a radial turbocompressor, the diffusor guide vanes 4, 5 each exhibiting a vane pin 6, 7 parallel to the axis of the ring and being supported rotatable about these pins 6, 7 in the casing 8 and being arranged at the vane pin control lever 9, which are pivotably connected to an adjusting ring 10, 11 supported rotatably at the casing 8. The radial turbocompressor has several stages. The rotors 2, 3 of two mutually adjacent stages in each case are arranged with the rear sides of the rotors facing one another. Each stage exhibits adjustable diffusor guide vanes 4, 5, the vane pins 6, 7 being attached in the first third of the diffusor guide vane 4, 5 facing the flow. The adjusting rings 10, 11 of the stages arranged with the rear sides of the rotors facing one another are adjustably connected to an operating ring 12. Thus, all diffusor guide vanes 4, 5 are synchronously adjustable, in which arrangement the adjustment can be controlled by a servo drive 13. This results in a control which allows operation within a wide range of different volume flows with constant pressure and largely constant efficiency. <IMAGE>
