Title: Spiral heat exchanger
Inventor: HAMPEL HEINRICH DR ING
IPC: F28D7/02
Filed: 1983-01-26
Abstract: The invention relates to a recuperative spiral heat exchanger having tube plates, in particular for refrigerating engineering and district heating. The known spiral heat exchangers have substantial disadvantages, specifically a complicated design of the heat exchange surfaces in order to provide them with an appreciable performance. The object of the invention consists in improving the performance of the spiral heat exchangers in terms of heating engineering, while simultaneously simplifying their internal structure, in conjunction with the large-area design of the heat exchange surface customary to date. The invention achieves the object set by realising in the spiral heat exchanger a counterflow instead of a crossflow, and achieving the uniformity of flow in the region of the spiral tube bundle.

Abstract: Standard pallets 1 with the basic measurements 800 . 1200 7 and 1000 . 1200 8 can be conveyed transversely on roller paths 6, by being dragged by snapper cams 3 with stroke lengths B. The stroke length corresponds to the distance between the snapper cams and is based on the maximum pallet width. See Figure 7. The pallets can also be conveyed longitudinally on the same paths with a snapper cam distance B1, according to Figure 8. If both sizes of pallet are to be conveyed simultaneously, a third strand of rollers is to be provided, whose snapper cams are also operated by the conveying mechanism of the main roller paths. The pallets are transported by means of a drive mechanism for the stroke length B, which consists of a guide carriage 18 with snapper cams 3, which advances the pallet by the length of a stroke in advance mode by means of an endless chain 25 via tensioning wheels 27, idler wheels 28 and the drive wheel 29 of the drive shaft 30. In reverse mode, the snapper cams are simply returned to their starting position. Figure 17 shows the position at the start of conveying, while Figure 18 shows the position after conveying. The front pallet in each case is transferred to the section of the group travelling in front. Additional guide carriages can be connected to the guide carriage 18 via tow bars and connecting rods with a length equal to B or B1, making it possible to convey pallets in groups with one drive. The length of the group can be adapted to the driving power. Conveying gaps can be filled by subjecting a group to a number of strokes. At the transfer points ...

Patent DE-3426523-A1 (DE)
Inventor: GRIES WILLI
IPC: B01D25/00
Filed: 1984-07-18
Abstract: A filter press (10) is supplied with material to be filtered by a filling pump (20) and a high pressure pump (26). Both pumps are connected in parallel and designed as eccentric worm pumps. The charging pressure is gradually raised to a final pressure without any temporary dropping so as to reduce the charging time to a minimum. In correspondence with the gradually decreasing absorption capacity of the filter press (10) first the normal speed of the filling pump (20) is lowered to a predetermined lower operating speed at unvarying speed of the high pressure pump (26). If required, then also the speed of the high pressure pump (26) is reduced. If the absorption capacity of the filter press (10) again increases, first the speed of the high pressure pump (26) is raised again to its former value and, if necessary, subsequently the speed of the filling pump (20) is increased again. A control means (52) including a microprocessor unit serves to vary the speed of the pumps (20 or 26) by way of speed control means (36,38). The inputs into the control means (52) are electrical signals corresponding to scanned "values" of the charging pressure. Guide and control magnitudes can be entered freely into the microprocessor unit in response to the properties of the filtering apparatus and the material to be filtered.
Patent DE-3433299-A1 (DE)
Title: Active thermal barriers
IPC: A62C35/00
Filed: 1984-09-11
Abstract: Intermediate spaces in frames or frame profiles are envisaged according to this invention as air-stream ducts which are intended either for cooling purposes or for heating purposes for windows or doors. Perforations made in advance in parts of a frame allow air-conditioned flows to be ducted either between or around panes of glass in a regulatable way, such that the latter can serve for creating thermal barriers. For the purpose of optimising the thermal characteristics of a window, door or partition of glass or other materials, this invention envisages laminating on a fabric or fibres of fibreglass, or others, by means of transparent synthetic resins, so that the transparency of the pane of glass is retained after curing of the plastic. In this way the temperature-controlled air stream ducted past is prevented from suffering major drops in temperature, thereby allowing the perfection of the intended thermal barrier to be accomplished.

Title: Slide drive of a blank feed device for presses
Inventor: BUENNING KLAUS
IPC: B21D43/04
Filed: 1984-09-13
Abstract: The aim is to achieve a low-wear slide drive which is easy to service, has a small overall size and allows large slide travels at high/speeds. The object is distortion-free and simple transmission of the required sequences of motion of the slide by using just one motion transmission element between the cam mechanism and the belt pulley and slip-free running of the belt drive. This is achieved according to the invention by the fact that a rotatable bell crank lever (1) is in operative connection with the cam mechanism (4) via rollers (3) while the end of one arm of the bell crank lever has a toothed segment (5) which drives a pinion (6) of a belt pulley (7), steel belts (8) running in opposite directions and offset relative to one another being arranged on the belt pulley (7) and being connected to a slide (10). By virtue of the constrained movement of the bell crank lever (1) articulated on the driven cam discs, the said lever executes an oscillating rotary motion with the toothed segment (5). This rotary motion is transmitted to the pinion (6) and to the belt pulley (7) connected to the latter. As a result, the steel belts (8) and the slide (10) connected to them have the desired rectilinear reciprocating feed motion imparted to them. <IMAGE>

Title: Method for relocating items of equipment which are lost in poured material or snow
Inventor: BERRETH LORENZ
IPC: G01V15/00
Filed: 1984-11-22
Abstract: The invention relates to a novel method for relocating items of equipment which are lost in poured material or snow, with the aid of an electromagnetic marking transmitter which is automatically switched on by attachment to a ferromagnetic holder or is automatically switched off by removal therefrom, in that a permanent magnet operates a reed switch or isolates the circuit element from the voltage supply by interrupting the magnetic field with the ferromagnetic holder. The invention is particularly suitable for use in the case of high-Alpine ski tours and in combination with collision protection. The marking consists of a plurality of short signals, which are repeated at relatively long time intervals at the frequency 457 kHz, which marking is sampled at an audible frequency such that an identification is produced which allows unambiguous association (as a result of the number, sequence and/or duration of the individual tones) and enables relocation using search apparatuses for those buried in avalanches or using AM pocket receivers having a ferrite antenna, without disadvantageously influencing existing signals, which may be present simultaneously, from marking transmitters for those buried in avalanches. <IMAGE>
