Patent DE-3619707-A1 (DE)
Title: Energy-saving circuit for continuous distillation plants
Inventor: VINZ PETER DR ING
IPC: B01D3/14
Filed: 1986-06-12
Abstract: The invention relates to an energy-saving circuit of the rectification devices in continuous distillation plants and various embodiments of this circuit. Apart from the entire waste heat of the depleted solution stream, the entire heat of dephlegmation can also be used by this circuit over a wide separation range for preheating the enriched solution. This heat recovery becomes possible with a co-current dephlegmator which is connected, on the vapour side, in parallel to the enrichment section of the rectification column and is preferably cooled by a part-stream of the enriched solution. At the same time, product vapour at the required purity and condensate for the reflux of the enrichment section of the column relieved on the vapour side are recovered in this manner from a part-stream of the vapour mixture present at the beginning of the stripping section of the rectification column. In the case of an ammonia/water absorption heat pump, by this energy-saving circuit, for example, the heating efficiency index can be increased from 1.3 to 1.5 and in addition the heating water admission temperature can be increased from 65 DEG C to 80 DEG C. The annual energy consumption of the underlying heat pump-district heating plant would thus be decreased by 23%.

Abstract: An apparatus for the heat and surface treatment of metal parts is designed as a unitary furnace installation in the form of a through-type installation, in which two reaction zones containing different atmospheres from one another are arranged one behind the other. The furnace installation has a common conveying device for both reaction zones. An atmosphere separation device is installed between the two reaction zones. The main advantage of this apparatus consists in that the metal parts to be treated can be handled in a particularly simple manner with it and the apparatus exhibits a particularly low energy consumption. <IMAGE>
Patent DE-3621847-A1 (DE)
Title: Vehicle wheel
Inventor: SPITZ WOLFGANG DIPL ING
IPC: B60B21/02
Filed: 1986-06-30
Abstract: The invention relates to a vehicle wheel with a pneumatic tyre, with a rigid rim which has essentially radially inwardly extending rim flanges, in each case one seating face on the radially inner side and in each case one flat bed centre for each tyre bead and run-flat support faces on the radially outer side, and with a tyre made of rubber or rubber-like plastics whose beads are arranged on the radially inner circumference of the rim next to the rim flanges and whose carcass is anchored in the beads by wrapping around bead cores.   In order to make the tyre easy to fit, it is proposed that the bead cores be designed to be more flexible and able to withstand a greater degree of stretching and crushing than tyres on previously known wheels of this type and that an annular and/or disc-shaped support body for absorbing radial forces be located radially inwardly from each tyre bead.
Patent DE-3623281-A1 (DE)
Title: Spacer and ventilating heat-insulating or cold-insulating and/or rapidly insulating insert
Inventor: MUEHLDORFER HELMUTH
IPC: E04B1/76
Filed: 1986-07-10
Abstract: In order to ensure the ventilation of the space between an insulating-material layer, inserted between supports, and the exterior covering or exterior cladding of ventilated roofs, exterior walls or the like, use is made of a spacer which is permeable to vapour and extends between the neighbouring supports such that, while maintaining ventilation ducts, it holds the insulating-material layer at a distance from the exterior covering or the retaining members thereof. In this arrangement, the spacer can stretch flexibly in the "longitudinal direction" extending between the supports, but, in the direction running transversely thereto, it is, in contrast, essentially inherently rigid in the installed state, between insulating-material layer and exterior cladding. <IMAGE>
Patent DE-3627292-A1 (DE)
Title: Process for adjusting section isolators with unground insulator and collector-slipper runners, and section isolator which is particularly suitable for carrying out the process
Inventor: FARKAS ALFRED ING
IPC: B60M1/18
Filed: 1986-08-12
Abstract: In the case of section isolators with unground insulator, the insulator is subjected to bending owing to the mechanical tensile stress present in the contact wire, said bending making it necessary to adjust, at the site of installation, the collector-slipper runners (10, 11) fastened on end fittings (2) of the insulator (1). In the case of the process according to the invention, this is avoided in that the section isolator is subjected, before installation into the contact line, to those mechanical conditions which are to be expected for it owing to the influence of the tensile stress, present in the contact wire, of a predetermined magnitude, and in that the adjustment at least of the collector-slipper runners (10, 11) is thereby effected. A number of applications of resultant forces are specified for this. For a section isolator which is particularly suitable for carrying out the process, the invention specifies a strut (24) which is in the form of a bar, can be adjusted in length and is intended at least for each of the longer collector-slipper runners (10), as well as a novel configuration of the end fittings (2) of the insulator (1) and tension elements (5) which are in operative connection with said end fittings and can be changed in length. <IMAGE>

Patent DE-3709644-A1 (DE)
Title: Door structure consisting of solid wood
Inventor: PEETZ HELMUT
IPC: E06B3/70
Filed: 1987-03-24
Abstract: Up until now, it was only possible to use solid wood for doors, in which the wood runs vertically over the entire door width, with sufficient protection against rupture perpendicularly to the growth direction if transverse or angle strips or metal bands were provided on the doors, which is not viable from the standpoint of aesthetic appearance. Moreover, the working of the wood led to impermissibly pronounced changes in width. The novel door structure is to avoid these disadvantages. In order to achieve the dimensional stability, the lining of the case comprising solid wood with glued block cores is fitted together with the claddings, on both sides, via tolerance-compensated groove-and-tongue connections, and the door leaf is made up of a plurality of planks which have glued block cores, connected to one another by groove-and-tongue connections and are held together by end-grained-wood strips which are connected to the individual planks in each case on a narrow strip. The end-grained-wood strips ensure dimensional stability, whereas the groove-and-tongue plug-in connections permit the wood to be worked.

Title: Method and device for obtaining a milk sample representative of a variable quantity of milk
Inventor: LANGE HEINZ
IPC: G01N1/20
Filed: 1987-12-18
Abstract: Known methods of the said type have a relatively complicated sequence and are not fully secured against falsifications of the sample taken. The novel method is intended to have a simple sequence and to eliminate falsifications of the samples. Furthermore, a device for carrying out the method is to be provided. In the novel method, two partial streams of milk are branched off parallel to each other from the main milk stream into two sample-taking containers (3) and (4), this taking place with different proportionality factors. Upon reaching the maximum level of the first sample-taking container (3) having the large proportionality factor, this is separated from the main milk stream, and only the partial stream with the small proportionality factor is branched off into the second sample-taking container (4). At the end of a filling process, the milk sample is extracted, according to whether the maximum level in the first sample-taking container (3) has been reached or not reached, either from the second sample-taking container (4) or from the first sample-taking container (3). The novel method, as well as the appertaining device, are especially suitable for application and use in milk collection vehicles. <IMAGE>
