Title: Linear segmented polyurethane elastomers
IPC: C07F9/6521
Filed: 1969-06-07
Abstract: Linear segmentedpolyurethane elastomers containing a chain extending segment of the formula wherein X is 1 or 2 may be prepared by reacting an NCO-terminated prepolymer suitably derived from a dihydroxy compound having a M.W. of 600 to 5000 and excess of an organic diisocyanate with a substantially equivalent quantity of an aliphatic semicarbazide hydrazide of the formula wherein x is 1 or 2 in the presence of a highly polar solvent. The prepolymer may suitably be prepared in the further presence of a diol having a M.W. of 62 to 300, which diol preferably contains tertiary amino groups in the molecule. Up to 45 mol. per cent of the aliphatic semicarbazide hydrazide may be replaced by a conventional bifunctional chain extender. Preferred solvents are those containing amide, urea or sulphoxide groups. The elastomer containing solutions may be spun into filaments. In a typical example (1) a polyester derived from adipic acid, 1,6-hexane diol and 2.2-dimethyl propane diol is heated with N,N-bis-(#-hydroxy propyl)- methylamine and diphenylmethane-4,41-diisocyanate in chlorobenzene to form an NCO- terminated prepolymer which is then reacted with a solution of #-semicarbazide propionic acid hydrazide in dimethyl formamide. The viscosity of the elastomer solution is increased by the addition of a further quantity of the NCO- terminated prepolymer, and after pigmenting with TiO 2 the solution is spun to form filaments.

Patent ES-395091-A1 (ES)
Title: Telecommunication system with transmitting stations selectively operable as temporary reference stations
IPC: H04B7/212
Filed: 1971-08-28
Abstract: A time-division-multiplex telecommunication system, with a multiplicity of ground stations communicating with one another via satellite, allocates to each ground station one or more subframes in a series of such subframes following one another in cyclic succession to constitute a sequence of signal frames. The first subframe of each frame, designated the reference subframe, serves for the transmission of frame-synchronizing signals from one of the stations of the system operating as a reference station, the latter sending out its address together with the frame-synchronizing code. In every other station, a counter triggered by an incoming frame-synchronizing code determines from that address the subframe allocated to the reference station and, in the one station using the next-following active subframe, generates an internal signal designating that station as a standby station to serve as a reference station if the actual reference station drops out. The standby condition is terminated upon reception of the next frame-synchronizing code but, in the absence of a predetermined number of such codes in successive frames, is converted into a reference condition whereby the affected station takes over the transmission of frame-synchronizing pulses.

Title: Self-dimensioning bearing assembly
IPC: F16C33/00
Filed: 1975-03-26
Abstract: A molded plastic pivot body is formed with an integrally molded sleeve bearing for journaling a pivot shaft of a windshield wiper system for a motor vehicle. The bearing includes concentric, radially spaced sleeves interconnected by webs disposed in the annular spaces between the sleeves. The inner sleeve is slotted axially, the slots being circumferentially spaced from each other. The annular spaces between adjacent webs form grease retainers and the slots serve as shaft lubricator as well as dirt collector grooves. The thickness of the outer sleeve wall is of a value which permits the outer sleeve to yield. The bearing is arranged on the pivot body support bracket unconfined so that the outer sleeve is free to flex. The segments formed by the slots in the inner sleeve are resilient and flexible. Radial forces applied to effect flexing of the segments is transmitted through the webs to the outer sleeve causing it to yield. A shaft of larger dimension than the inner diameter of the inner sleeve may be accomodated.
Patent ES-441258-A1 (ES)
Title: Installation for changing the temperature of fluid media, particularly for cooling liquids and condensing vapors with air
IPC: F28B5/00
Filed: 1975-09-25
Abstract: An installation for changing the temperature of fluid media has a gas-liquid contacting arrangement and an indirect heat-exchange arrangement. The gas-liquid contacting arrangement is made up of a chamber and a device inside the chamber through which liquid may flow to be converted into the form of a spray. A collecting vessel at the bottom of the chamber collects the liquid which passes through the spray device. The wall of the chamber is provided with openings for the admission of a gas into the chamber and louvers may be provided for regulating the flow of gas into the chamber. The indirect heat-exchange arrangement is made up of two portions which are located at a level above that of the spray device and which extend upwardly and outwardly from the vicinity of the wall of the chamber. Each of the heat-exchange portions is constituted by a plurality of parallel conduits provided with fins. Where the installation is used for cooling purposes, the heat-exchange portions may serve as condensers. The heat-exchange medium used for the heat-exchange portions is a gas. An inflow passage for this gas, as well as the gas which is to flow into the chamber, is provided below the heat-exchange portions and is in part defined by the wall of the chamber and either an end wall of the installation or the wall of an adjacent chamber. A ventilator arranged directly above the chamber produces a suction which draws gas through the chamber and by the heat-exchange portions, thereafter mixes the streams of gas and vents the gas to the atmosphere. The installation is particularly useful for the cooling of a liquid and the condensation of a vapor using air as a cooling medium. More than one contacting arrangement and heat-exchange arrangement may be provided. In such an event, adjacent heat-exchange portions may cooperate to define a heat exchanger of inverted V-shape. A ventilator is located above each chamber and at a level above the apex of the inverted V-shape heat exchanger. A particularly useful construction is obtained when such an inverted V-shape heat exchanger is located between each pair of gas-liquid contacting arrangements.

Title: Method of burning calcined and uncalcined pulverous raw material and rotary kiln plant therefor
IPC: B01J6/00
Filed: 1976-04-15
Abstract: A method is disclosed for heat treating a preheated pulverous raw material containing at least a portion of lime to produce a partial calcination prior to passing the raw material down through an inclined rotary kiln for further heat treatment. Partial calcining is accomplished by introducing into at least one end of a rotary kiln an amount of fuel sufficient for preheating, at least partially calcining, and substantially completely sintering the raw material, at least part of the fuel being introduced into the lower material outlet end portion of the kiln. An amount of oxygen containing gas sufficient for substantial combustion of the fuel introduced into the kiln is introduced into the lower end portion of the kiln, and preheated raw material is introduced into the mouth of the kiln in such a manner that the material is entrained in gases exiting from the kiln mouth. The gas and entrained material exiting from the kiln are directed into a calcination chamber communicating with the upper material inlet end portion of the kiln such that the material is at least partially calcined by the contact with the kiln exit gases. The material is thereafter separated from the kiln exit gases and reintroduced into the upper end of the kiln in a manner which permits it to pass through the kiln for further heat treatment while avoiding entrainment in the kiln exit gases. A rotary kiln plant for practicing the method is also disclosed which provides for at least partial calcining of the material initially introduced into the kiln and thereafter reintroducing the partially calcined material in such a manner as to promote passage down through the kiln for further heat treatment.
