Abstract:
A molten substance is consolidated by being deposited onto a cooling belt which conveys the substance through a space formed between the belt and an overhead hood. The formation of exhaust dust from the substance is minimized by controlling heaters in the hood to vary the temperature along the space such that the saturation pressure in the space closely matches the vapor pressure of the substance as the substance travels through the space. Also, the hood is placed close to the cooling belt to minimize the velocity of vapors emitted from the substance within the space.
Abstract:
Aqueous dispersions of certain amines, with Bronstedt acids having a pKa of at least 6, are stable and are useful as rinse-added fabric softeners.

Abstract:
A flowable material, such as a supercooled melt or supersaturated solution, is dispensed onto a take-up member such as a belt or drum. Either prior to, or after being dispensed onto the take-up member, the material is exposed to ultrasound to promote the crystallization of solid substances in the material. All of the material or only a portion of the material can be exposed to ultrasound. If only a portion is exposed, it is later combined with the rest of the material prior to being dispensed onto the take-up member.
Abstract:
After being subjected to a melt crystallization operation, a crystal-containing melt is formed into particles of the same size and shape and then conducted in counter-flow relationship to washing liquid in a washing column. The crystal-containing melt can be formed into particles by a device which deposits the crystal-containing melt as identically sized drops onto a cooling belt. The particles can be completely hardened or only partially hardened when entering the washing column.
Abstract:
A mechanism for making granulated material from a viscous substance includes a vessel charged with the substance and having a discharge opening arrangement for discharging the substance onto a cooling surface. A belt travels across the vessel, the belt having openings arranged to periodically come into alignment with the discharge opening arrangement to allow the substance to fall onto the cooling surface. The discharge opening arrangement comprises a plurality of rows of discharge openings. Each row extends transversely of the longitudinal direction of belt travel, and the rows are spaced apart in that longitudinal direction. The vessel openings of each row are offset in the transverse direction with respect to the vessel openings of other rows. A collection arrangement collects residual substance falling from the belt and returns the substance onto the belt at a location upstream of the vessel.
Abstract:
A pump for fluid media having different temperatures. The pump has two chambers for the two media, respectively, each chamber having an inlet and an outlet each provided with a respective check valve. The chambers are separated by a displacement body whose shape is a function of temperature and which, upon a change in shape due to a change in temperature, changes the sizes of the two chambers. The displacement body is arranged in the two chambers such that initially there is a greater heat exchange between the displacement body and the fluid in one of the chambers than there is between the displacement body and the fluid in the other of the chambers, but that subsequent to the shape change brought about by the heat exchange between the displacement body and the fluid in the one chamber, the heat exchange between the displacement body and the fluid in the other chamber will be greater than the heat exchange between the displacement body and the fluid in the one chamber.
Abstract:
The disclosed embodiments relate to a power supply network with integrated undervoltage protection for the energised consumers in a passenger aircraft having multiple consumers, with a power supply having multiple output connectors, wherein each consumer is connected to one of the multiple output connectors via a main supply wire, wherein each of the multiple consumers includes at least one individual load, each of which is designed for a predetermined supply voltage range. In order to ensure that the power consumption of individual consumers in a passenger aircraft power supply network is only limited relative to the overall power output to the extent that is absolutely necessary according to the requirements of overriding general conditions, and at the same time to minimise the corresponding weight of the cables in the aircraft, each of the multiple consumers according to the invention includes a voltage sensor for recording the supply voltage and a load controller, wherein the power draw of at least one individual load of the respective consumer is reduced when the supply voltage at the respective consumer falls below the preset minimum value.
Abstract:
A device is disclosed for improved coating of small solid particles with a melt of a material which solidifies at room temperature. The device includes a rotatable turbine body and conduits for supplying solid particles and molten material to the rotatable turbine body. The turbine body is rotated by a hollow drive shaft and is provided with a series of heating conduits extending through the drive shaft and the turbine body for heating the turbine body. The turbine body can be heated to a controlled temperature to maintain the molten material at a desired temperature by varying the temperature of a heating agent which is supplied through the heating conduits.
Abstract:
A device is disclosed for improved coating of small solid particles with a melt of a material which solidifies at room temperature. The device includes a rotatable turbine body having two rotatable disk parts. An annular gap is provided between the rotatable disk parts which allows the melt to emerge to coat the solid particles in an annular space. The two rotatable disk parts are connected by a fine-pitch thread which allows the size of the annular gap to be adjusted by rotating one of the disks relative to the other. Rotation of one of the disks is performed from the exterior of the device by an adjusting pin which eliminates the need to dismantle the device to adjust the flow of the coating material.
