Title: Process for the optimum purification of water and air in paint shops and paint spraying booths having water-irrigated back and side walls by means of a paddle roller
Inventor: HAAS ROLAND DIPL ING
IPC: B05B14/46
Filed: 1985-05-13
Abstract: The invention relates to a process for the optimum purification of air/paint/water mixture in paint shops and paint spraying booths so that the exhaust air exiting into the open is environmentally friendly and free from exhaust gases which are hazardous to human and animal health and hazardous to nature. At the same time, a simplified and cost-saving purification of paint sediment is effected in the exhaust air channel in paint shops and paint spraying booths. This is achieved by mounting paddles in the longitudinal direction on a roller. This roller is mounted on spacing bridges which are attached between the vertical baffle wall and the irrigation wall in wet paint shops. The mounting must be performed above the lower edge of the irrigation wall, so that the gravitational force of the irrigation water and the draft in the exhaust air channel can set the roller in rotation without supply of energy. It must completely fill the space between the irrigation wall and vertical baffle so that both exhaust air and paint mist are forced to be rolled into the irrigation water.

Patent DE-3619569-A1 (DE)
Title: Manually moveable trolley
Inventor: SCHMID JOHANN
IPC: B62B3/14
Filed: 1986-06-11
Abstract: Trolleys, the front wheels of which are designed as support wheels, can be moved relatively safely across a slope without drifting off laterally. On the other hand, a line of trolleys pushed together is difficult to move around a bend because the front support wheels do not participate in the steering action. This disadvantage is avoided by a manually moveable trolley (1), the wheels (8, 9) of which are all designed as steering wheels, in that a locking mechanism (26) is provided between the loading surface (17) and the chassis (2) and in that when the loading surface (17) is swivelled, depending on its angle of adjustment, part of the locking mechanism (26) either protrudes into the swivelling region of the front wheels (8) or is located outside the swivelling region of the front wheels (8). As a result of this measure, the front wheels (8) adopt the function of support wheels in straight-ahead running whereas in a line of several trolleys (1) they act as steering wheels. <IMAGE>

Title: Piece of upholstered seating furniture with a footrest adjustable relative to the seat part from an unused position to a supporting position
Inventor: A GOELLER KURT
IPC: A47C7/50
Filed: 1986-07-30
Abstract: In the case of a piece of upholstered seating furniture with a footrest which is adjustable relative to the seat part from an unused position to a supporting position, the seat part and the footrest merge into one another without interruption at least at the upper side. In this arrangement, the footrest has a bearing arrangement which is tiltable in such a way that the footrest can be tilted relative to the seat part within the range between approx. 90 DEG (unused position) and 0-30 DEG  (supporting position). As a result, the footrest is integrated into the upholstery of the seat part, and no disturbing interruption in the supporting position results. In the unused position, the downwardly pivoted footrest forms the front end of the piece of upholstered seating furniture. On pivoting upwards, a movement directed away from the seat part is imparted to the footrest, in order that the continuous upholstery is largely crease-free even in the joining region between seat part and footrest.

Title: Hydraulically inwardly pivotable ground-working implement
Inventor: FERSCHITZ ALOIS
IPC: A01B39/26
Filed: 1986-09-01
Abstract: A hydraulically inwardly pivotable ground-working implement, the automatic control of which is possible with a very small number of parts, is described. The ground-working implement is seated on a cutter bar (3) which is connected fixedly in terms of rotation to a shaft (2). The position of the rotatable shaft (2) and of the cutter bar (3) is determined by means of a hydraulic cylinder (6). Fitted rotatably on the shaft (2) is a sleeve (7), to which a tracer (8) is fastened. The shaft (2) and the sleeve (7) have respective bores which, depending on the relative position of these two parts (2, 7), form a channel (12, 13) of differing transitional cross-section. The pressure with which the cylinder (6) is loaded is regulated by means of these channels (12, 13). When the appliance is moved in the direction of the arrow (10), the tracer (8) is pressed rearwards by an obstacle according to the representation of Figure 1, to the left in relation to the direction of movement by an obstacle, with the result that the pressure changes so that the cutter bar (3) is also thereby moved to the left or to the rear.

Filed: 1986-09-10
Abstract: The invention relates to a tiled stove in which, according to the invention, a flue gas-regulating flap (26) is fitted in a connecting opening (6) between a combustion chamber (3) and a heat-exchanger chamber (4). This flue-gas flap (26) is part of a temperature-regulating circuit having a temperature sensor (33) in a flue-gas pipe (21) immediately in front of the chimney inlet. The desired temperature value of a temperature regulator (32) is set so that, with the aid of the regulating flap (26), the temperature is adjusted to a temperature lying above the sooting temperature of the chimney. Furthermore, between the flue-gas pipe (21) and a convection-heating box (23) there is situated a heating-up box (20), from which, during the heating-up process, the convection-heating box (23) can be cut off and a direct flue-gas path to the chimney can be connected. With the arrangement according to the invention, as well as protection of the chimney against sooting, good fuel utilisation is achieved and the risk of condensate formation in the stove components is reduced. <IMAGE>

Title: Method for developing and copying photographic films
Inventor: HUEBEL EGON DIPL ING
IPC: G03D15/00
Filed: 1986-12-29
Abstract: Exposed photographic films (1) are developed in photo labs. Copies (18) are subsequently produced. In the event of later repeat orders, the customer faces the problem of identifying negatives. The tasks thereby arising are: simplifying the process for repeat orders of photographic images for the customer, and providing the preconditions for automation measures. The object is achieved according to the invention by means of a method in which each individual negative image (6) of the film (4) is assigned an individual distinguishing mark (identifier, tag) (15) in the photo lab, and in which a distinguishing mark (16), which corresponds to this distinguishing mark (15), is applied to the corresponding copy (18). The distinguishing marks (15, 16), which can be read by a person and/or machine, permit unambiguous assignments by the customer and during filling of the repeat orders for copies in the photo lab, as well as automation measures. <IMAGE>

Title: Rainproof roof for spoked clothesdriers
IPC: D06F57/04
Filed: 1987-01-24
Abstract: The solution, proposed in the Main Patent P 3618947, for a rainproof roof for spoked clothesdriers still has the disadvantage of too high a construction outlay since two aluminium tubes are used for winding up the plastic sheet and, moreover, an extension bar, which can be fastened on the top upright-leg end and raises the plastic sheet to form a pointed roof, is required. This disadvantage is eliminated according to the invention in that each fastening member for a drier-arm end comprises an angled-off part, one leg of which is screwed, clamped, plugged or directly connected onto the drier-arm end and the other leg of which is bent off to such an extent that, after fastening the angle part on the pivoted-out drier arm, it is directed downwards and on whose upper side there can be screwed a strip which has a plurality of perforations or is provided with a longitudinal slot.

Patent DE-3730950-A1 (DE)
Inventor: WIESMANN HANS
IPC: C02F1/70
Filed: 1987-09-15
Abstract: The concentration of sulphuric acid waste from the manufacture of titanium dioxide is increased by evaporation from 65 to 70 %. It is aged for several days, during which time the metals dissolved in the acid are generally precipitated in sufficient quantity, with exception of chromium and vanadium. In order to precipitate the chromium in a sufficient quantity in a sufficiently short time, 0.3 % by weight of aluminum is added to the evaporated acid waste. The aluminum has an active surface and is obtained shortly before addition by machining, size reduction or comminution. The strongly negative redox potential of this aluminum gives rise to chromium of obviously lower valency, whose salts are less soluble than those of the higher-valency chromium or metallic chromium, and which can be precipitated more easily.
