Title: Process and apparatus for separating thermally sensitive multi-component mixtures in vacuum
Inventor: GUTWASSER HELMUT
IPC: B01D1/06
Filed: 1983-09-23
Abstract: The invention relates to a process and an apparatus for separating degassed and dewatered thermally sensitive multi-component mixtures in vacuum. The aim and object of the invention are to ensure the attainment of high yields of a colour-stable main fraction of good quality with complete separation of residue and first runnings and with low consumption of energy and low expenditure in terms of apparatus. The object is achieved according to the invention in that the multi-component mixture is divided into two fractions at 300 to 500 Pa, from which, at 100-200 Pa, by evaporation and condensation and circulation of the vapours containing non-condensing first runnings, a first main fraction, the residue, a second main fraction and, if present in the multi-component mixture, first runnings are successively condensed. The separation of this multi-component mixture is carried out in only one column which is furnished with external and internal heat exchanger surfaces and is subdivided by chambers into a plurality of functional spaces. The vapour velocities in counter-current flow are 30 to 50 m/s. The first runnings fractions can be removed to a level lower than 0.1%, for which purpose only small reflux rates are required.

Title: Process for producing boron-doped polycrystalline silicon layers for bipolar-transistor circuits
Inventor: SCHABER HANS-CHRISTIAN DR RER
IPC: H01L21/324
Filed: 1984-01-23
Abstract: The boron-doped polycrystalline silicon layer (6) is produced in an amorphous state by a chemical deposition process from the vapour phase at T </= 580 DEG C and is converted into the polycrystalline state in a subsequent high-temperature process (T >/= 800 DEG C). By means of the process it is possible to produce very low-resistance base terminals in bipolar integrated transistor circuits; owing to the reduction of the internal base resistance RB, the transistor switchover times are substantially shortened. <IMAGE>

Patent DE-3407374-A1 (DE)
Inventor: BREITHAUPT UDO DIPL ING
IPC: C13B50/00
Filed: 1984-02-29
Abstract: To convert syrups deriving from sugar production and other foodstuffs into a powder or granulated form subsequent to appropriate preliminary concentration and while preserving the product subject to the most extensive possible maintenance of the original composition, a sugar solution with at least 70% dry matter and up to 15% non-sucrose materials in the dry matter is brought by product-preserving rapid heating to a high temperature. Subsequently the vapors are allowed to escape to a dry-matter content of at least 90% and the thickened syrup is converted into a dry and pourable product just by cooling and sudden extraction of the residual water through crystallization. This preferably occurs in equipment comprising a steam-heated spiral-tube heat exchanger with a spiral tube that tapers out to 150 to 200% of its original free cross-section and has built-in twist generating baffles, a vapor precipitator to atmospheric pressure, and a crystallizer below the precipitator.
Patent DE-3409020-A1 (DE)
Title: Serving trolley
Inventor: BUTENSCHOEN ROLF
IPC: A47B31/02
Filed: 1984-03-13
Abstract: The serving trolley is constructed in such a way that the food, for example cheese, which is placed on the resting surface under a hinged covering hood, is cooled by a refrigeration assembly 13 and additionally kept moist by an air humidifier 14 in such a way that no drying-out occurs which would take place under normal cooling. Rechargeable batteries 17 supply the air humidifier when the serving trolley is in operation, i.e. is rolled from one table to another in a restaurant. The refrigeration assembly is then switched off. However, the cold stored, in particular, in the water supply of the air humidifier prevents the food from becoming too warm during this not unduly long period. The latent heat likewise ensures an appropriate, slower warming. When the serving trolley is not in normal operation, it is supplied with electricity via a mains connection and the refrigeration assembly operates. The batteries are then charged. Considering a 24-hour rhythm, the period in which the serving trolley is not in normal use is very much longer than its use in the restaurant or the like. <IMAGE>

Title: Apparatus for winding textile yarns having a directly driven winding spindle
Inventor: LOHEST HANS
IPC: B65H59/38
Filed: 1984-05-17
Abstract: The invention relates to an apparatus for winding continuous textile yarns at a winding speed which is constant over the winding travel, in which the winding reel is driven directly by a winding motor. The continuous variation of the driving or winding speed, which is necessary at the same time, takes place by means of a corresponding variation of the frequency of the three-phase current driving the winding motor which is a three-phase asynchronous motor. The variable frequency is generated in a frequency generator which is supplied from the normal three-phase network. According to the invention, a transformer is interposed between the frequency generator and the motor and makes it possible to tap at least two different output voltages. The change-over from one voltage to the other takes place in dependence on the progress of the winding operation by means of devices which convert suitable parameters in the change-over pulse.

Title: Axial threshing machine
Inventor: GRIEMERT HEINZ
IPC: A01F12/44
Filed: 1984-07-26
Abstract: The invention relates to an axial threshing machine with a threshing drum, with a threshing-basket arrangement surrounding this over part of its circumference, and with a conveying floor located underneath the threshing-basket arrangement and intended for collecting the threshed material and conveying it in the axial direction to a screening arrangement located downstream, the conveying floor having guide strips for the threshed material which extend in the axial direction as far as a rear delivery edge above the screening arrangement. Threshing machines working according to the axial-flow system have, over the width of the conveying floor, a non-uniform distribution of the deposited threshed material which also essentially continues on the screening arrangement. Cleaning air flows through the threshed material on the screening arrangement and encounters greater or lesser resistance, depending on the amount of threshed material occupying it, with the result that the threshed material is also cleaned non-uniformly. To prevent this, it is proposed, according to the invention, to arrange the guide strips (21) on the conveying floor (9) in such a way that the regions (B) limited thereby diverge (B-1) in the direction of the rear delivery edge (11) of the conveying floor in the region of a high feed of the conveying floor (9) with threshed material (D) from the threshing drum (2) and converge (B-2, B-3) correspondingly in the region of a low feed. <IMAGE>

Title: Thermal block as a vehicle energy store
IPC: F28D20/00
Filed: 1984-09-06
Abstract: Exhaust gases and noise are still problems which are heard and smelt daily and over which to get heated. This could be changed, cars could whisk softly along odourlessly and make much better use of the energy in their tanks. It could be pleasantly cool in the car in the event of hot weather. This would be possible by means of a block made from metal or hard ceramic. The aim is to insert it in a heated state into an insulated container in the car, or to heat it in advance or in the container. In order to use the stored energy effectively, the boiling point of the liquid which effects the conversion to electrical energy by virtue of evaporation is to be selected as low as possible, but at the same time is to be capable of condensation by the slipstream. The evaporation is to take place in tubes which taper upwards and are to be arranged in a row, so that an axle with vanes which is arranged transversely thereabove can be forced to rotate. The slipstream is intended initially to cool the vapour, after which it is to be led partially along below the covering sheet metal of the car for cooling purposes, reaching the block in a heated state for the purpose of storing the absorbed heat, or directly to the evaporator liquid for the purpose of converting the absorbed heat into current. In the transition phase, when there are still not enough filling stations for refilling with heat, the block could be reheated in emergencies by burning clean gas which is carried along. Stationary combustion plants could also store their heat in stationary blocks, such blocks ... Original abstract incomplete.

Title: Process for catalytic coal hydrogenation, using a direct coal suspension as reactor charge
Inventor: COMOLLI ALFRED G
IPC: C10G1/08
Filed: 1984-11-27
Abstract: In a process for improved catalytic hydrogenation of coal to produce low-boiling hydrocarbon liquids and gaseous products in increased yields, a coal/oil suspension is fed directly with only limited heating into a catalytic fluid-bed reaction zone to induce an increased conversion in hydrogenation and improved yields of low-boiling hydrocarbon liquids. In the process, coal is suspended in a hydrogenated liquid originating from coal and heated only to a limited extent which is defined by a severity temperature/time unit index (STTU) of less than about 0.1, so that an exhaustion of the hydrogen donor capacity of the solvent liquid is avoided, and the suspension is then directly fed into a catalytic fluid-bed reaction zone which is held at a temperature of 340 to 480 DEG C (650 to 900 DEG F) and at a hydrogen partial pressure of 70 to 350 bar (1000 to 5000 psi). Additional heat is supplied if required to the reaction zone by heating with a recycled reactor liquid and recycled hydrogen streams to temperatures above the reaction zone temperature. If desired, liquid leaving the reaction zone can advantageously be passed on with hydrogen to a second catalytic fluid-bed reaction zone for a further hydrogenation reaction at ...
