Patent EP-0017944-A1 (EP)
Inventor: GRANT ANDREW CAMPBELL
IPC: F28F13/18
Filed: 1980-04-14
Abstract: A method for producing a porous boiling surface with exceptional adhesion qualities and mechanical strength while at the same time maintaining the high degree of open cell porosity required for effective boiling heat transfer wherein a bond coating of pure aluminum is produced using a thermospray gun to melt an aluminum wire and impinge the molten aluminum particles against the metallic substrate in an inert gas stream projected from the gun nozzle located between 2 and 4 inches from the substrate. The bond coating has a porosity of less than 15 percent and a thickness not greater than 4 mils. The nozzle to substrate distance is then increased to 4 to 10 inches and a top coating of pure aluminum is formed having a porosity greater than 18 percent and a thickness of at least four times the thickness of the bond coating.

Abstract: For removing and dissolving sand mold residues from cast parts, particularly sand mold residues containing zirconium oxide and titanium oxide, there have previously been used mechanical and electrochemical processes in salt melts. However, these processes are very expensive, attack the surface of the cast pieces or fail to work with sand mold constituents which are difficult to dissolve. These disadvantages are avoided by inserting the cast parts having adhering sand mold residues into a melt of 55 to 97 weight % of alkali metal hydroxide and 3 to 45 weight % of one or more fluorides of an element of the first to third main group of the periodic system of elements and/or zinc at 400 DEG  to 900 DEG  C. Preferably the salt melt additionally contains a boron-oxygen and/or a boron-fluorine compound.

Abstract: An ultrasonic testing method in which a hf transmitting/receiving coil (14) and a magnet are moved adjacent the workpiece surface, hf pulses are fed to the coil and the signals induced in the coil are amplified by an amplifier (27) suffers from the disadvantage that the induced signals vary in strength with variation of the distance of the coil from the workpiece. The electromagnetic coupling factor between the coil and the workpiece is monitored, e.g. by measuring the transmission voltage applied to the coil, and the amplification factor of the amplifier (27) is controlled in dependence on the variation of this coupling factor.

Abstract: The disclosure relates to a method of binder removal from a green body before sintering or the like wherein the green body is placed in a pressure chamber wherein the pressure is raised to a level above the vapor pressure of the binder in the green body at the ambient temperature within the pressure chamber. Where several binders are utilized simultaneously, the pressure within the chamber is maintained higher than the vapor pressure of the lowest of the binders then in the green body at the temperature within the green body. Under these conditions, the binder or binders will turn to a vapor, will follow the normal laws of evaporation and diffusion and diffuse out from the green body into the surrounding environment within the chamber. The binder can subsequently be removed from the chamber in conventional manner.

Abstract: Circuit de syntonisation manuelle pour une radio (10) a modulation d'amplitude et/ou a modulation de frequence dans lequel on fait varier intentionnellement la grandeur des signaux radio audibles par rapport a la valeur d'un signal d'erreur en relation avec la difference absolue entre la frequence desiree d'un signal porteur module recu et la frequence a laquelle l'extremite anterieure du circuit radio (11-17) est syntonisee. De cette maniere, l'on peut obtenir une syntonisation precise de l'extremite anterieure du circuit radio a la frequence desiree en recherchant le volume maximum des signaux radio audibles. De preference, ceci est obtenu par l'utilisation d'un redressement d'onde pleine de la tension continue de sortie du discriminateur (35) de modulation de frequence ou d'un redressement d'onde pleine de la tension de commande pour un oscillateur commande en tension (VCO) (26) dans une boucle d'asservissement de phase (24) en accord decale avec le signal de sortie (IF) d'un etage (IF) (16) d'une radio a modulation d'amplitude et de frequence.

Abstract: Bivalent heating systems of conventional type are equipped not only with a heat source for the direct heating mode, but additionally with an absorption heat pump whose coolant circuit is coupled to the heating medium circuit via heat exchangers. This means a not insigificant additional cost in system parts, and consequently system costs, for a heating system which has to be operated only on the few very cold days of the year while the heat pump mode is adequate for the far longer time. According to the invention, these system costs can be substantially reduced if the burner (2) of the heat pump is designed in such a way that it can be run with higher power and a bypass (6) with switching means (7) to suppress the rectification is provided at a suitable point in the circuit. When most of the coolant solution is flowing through this bypass during the operation of the heat pump, the rectification, which is per se desirable in the normal heat pump mode, collapses. The ammonia circuit contains a relatively large amount of water. The system can be run as direct heating at relatively low pressures. In addition to the saving in system costs, those problems also vanish which may possibly occur in switching over the conventional systems from one heating mode to the other. <IMAGE>
