Abstract: Abstract of the Disclosure Apparatus for separating a sublimation product from a gas which contains this product in the form of vapour, comprising an elongate casing, the wall of which is provided on the outside with heat-exchanging means which cool this wall below the sublimation temperature during the subliming process, the gas flowing longitudinally through the casing.  Under the action of the heating element, which extends longitudinally through the casing over the greater part of the length thereof, the temperature is raised locally to such an extent that no subliming can take place around this heating element.  As a result, there always remains an open channel through which the gases can continue flowing through the apparatus, so that no clogging can occur.  According to a further improvement, the casing is arranged with the longitudinal axis in horizontal or substantially horizontal position, the eccentric heating element being placed in the upper part of the casing.  These measures obviate the risk of lumps of sublimation product becoming suddenly detached, for example during subsequent heating-up of the apparatus, and, in falling, either damaging the internal parts of the appa-ratus or producing an abrupt difference in load, which could also be a source of damage.

Abstract: ABSTRACT OF THE DISCLOSURE     A process for removing the impurities, such as arsenic, antimony, bismuth, and/or lead, from a metal sulfide melt, such as copper sulfide melt, in which there is a melt solubility gap between the metal to be refined and its sulfide, in which the metal sulfide melt is first sulfidized in order to shift the composition of the melt away from the range of the solubility gap and the sulfidized metal sulfide melt is thereafter exposed to a selective chlorination to remove the impurities as vaporiz-able chlorides from the metal sulfide melt by a technique known per se, while the sulfur concentration in the melt is simultan-eously controlled in such a manner that the composition of the melt remains outside the said melt solubility gap.

Abstract: PNEUMATIC SYSTEM FOR SOLDER LEVELING APPARATUS             ABSTRACT OF THE DISCLOSURE         A solder levelling machine which uses a hot gas emanating from opposed gas knives to remove excess molten solder from a printed circuit board as the board is with-drawn from a bath of molten solder contained in a self-purging solder pot.  The hot gas clears the through-holes in the circuit board and allows a controllable desired thickness of solder to remain on the board and in the through holes.  A pair of heaters supplies the hot gas to the knives through a manifolding arrangement.

Abstract: "MOVABLE ICE RECEPTACLE"                 ABSTRACT OF THE DISCLOSURE         A movable ice receptacle for use in a refrigeration apparatus having a refrigerated cabinet defining a space within which the receptacle is normally disposed and which is selectively closed by a movable closure.  The receptacle is mounted for selective disposition in a rearward ice storage position and a forward ice access position.  The mounting of the receptacle is such that, when the closure is moved to an open position, the receptacle is correspondingly repositioned forwardly from the storage position to the access position.  The receptacle may be gravity biased toward the forward ice access position and urged against the bias thereof by structure associated both with the closure and the receptacle to move the receptacle to the rearward storage position as an incident of the closure being disposed in the space-closing position.  The mounting structure may be arranged to swingably mount the receptacle for movement in an arc.  The storage position may be at a level above the level of the access position.  The swinging movement may have a maximum speed when the receptacle is at the access position.  At the access position, the receptacle movement may be substantially horizontal.  A sensing element may be extended downwardly into the receptacle to sense the level of ice therein when the receptacle is in the ice storage position.  As an incident of movement of the receptacle from the ice storage position to the access position, the sensing element may be urged automatically by the receptacle mounting means to a shutoff position to prevent further operation of the ice maker at that time.
