Patent DE-3508276-A1 (DE)
Title: Water softening equipment
Inventor: HEISSMEIER WALTER DIPL PHYS
IPC: B01J49/75
Filed: 1985-03-08
Abstract: Water softening equipment is provided with a feed line 5 which feeds an ion exchange vessel 2. A channel 9 branches off from the feed line 5, which channel opens out into a storage vessel 10 and receives regeneration water which is conducted through a salt brine vessel 12 via a shut-off valve 14 into the ion exchanger for regeneration. In order to be able to design the storage vessel simply and to achieve matching of the salt brine consumption to the amount of feed water, which has not been previously softened, actually conducted through the ion exchange vessel 2, only the determined amount of regeneration water is branched off, via the channel 9, from the defined amount of feed water, which is flowing through the feed line 5, which is just required to regenerate the ion exchanger. <IMAGE>
Patent DE-3514027-A1 (DE)
Title: Turbocharged motor vehicle injection engine
Inventor: DOSTLER WERNER
IPC: F02D23/02
Filed: 1985-04-18
Abstract: In a turbocharged motor vehicle injection engine an electrically actuatable, normally connected solenoid valve (3) is provided in the air line (2) between the intake pressure pipe and the supercharging pressure-dependent stop of the injection pump of the engine, which valve can be triggered by means of a pulse from an engine speed or speed of travel limit sensor (4) when the limit is exceeded in order to interrupt the air line (2) and to vent the charging pressure-dependent stop. By simple means in certain operating states favourable fuel consumption values can thereby be obtained.
Patent DE-3518506-A1 (DE)
Title: Low-pressure closure for gaseous and fluid media, having a ball/detent connection
Inventor: STEIGERWALD NIKOLAUS
IPC: F16L37/42
Filed: 1985-05-23
Abstract: A closure, automatically, on the one hand with a compression spring and closing with a pressure medium, in the case of which the closing ring is a standardised part and is guided by means of a column guide.   Closing parts on closures were until now generally guided using tube-like hollow bodies, the passage at the terminating point of the closure being as narrow as the hole in the hollow body. In contrast, the column guide has a passage at the terminating point of the closure which is larger by the size of the free space between the columns. The closure is equipped with a ball-detent connection of known type, in the case of which, however, the compression spring of the operating sleeve does not stop in the normal manner on a collar of the closure body but is supported on a stop ring which is fitted on the closure body. It is thus possible to save material for the closure body.
Patent DE-3519595-A1 (DE)
Title: Connecting device for carrier strips equipped with adhesive labels
Inventor: YADA KAZUAKI
IPC: B65C1/00
Filed: 1985-05-31
Abstract: In the connection of the ends of two successively supplied carrier strips equipped with labels, the rear side of the rear end of the leading carrier strip (2a) supplied from a carrier-strip supply position is connected in an overlapping relationship to the front side of the front end of the trailing carrier strip (2b). The so connected front end of the trailing carrier strip cannot come loose from the rear end of the leading carrier strip when the interconnected ends turn about a sharp label separator (1) of a label-attaching device, since the front end of the trailing carrier strip is covered by the rear end of the leading carrier strip. After the carrier strips are thus connected to one another at their ends, supports (5, 16) for the trailing and the leading carrier strip are changed over or displaced in order to bring the trailing carrier strip into the carrier-strip supply position. A continuously successive supply of labels is consequently possible as a result of the connection according to the invention of two successively supplied carrier strips equipped with labels. <IMAGE>

Patent DE-3526866-A1 (DE)
Inventor: FOERSTER SIEGFRIED DR
IPC: F23D11/44
Filed: 1985-07-26
Abstract: A vaporizer for liquid fuel for producing a fuel-air mixture including a vaporization member for the fuel and which is arranged within a flow chamber for combustion air. The surface of the vaporization member which is streamed against by the combustion air is moistened with fuel. The vaporizer incorporates a vaporizing member arranged within a flow chamber for combustion air, wherein the vaporizing member includes a rotatable or circulating filling or charge of balls whose temperature can be adjusted through heat conduction received from the walls of the flow chamber. Thereby, through the revolving or circulation of the ball filling, and the heat transfer to the balls which are currently at the edge of the ball filling in heat-conductive communication with the temperature-regulated walls of the flow chamber, there takes place a rapid and uniform heating of the ball filling. The large vaporization surface which is made available through the ball filling, additionally allows for the formation of relatively thin fuel films, which can be heated while concurrently avoiding excessive temperatures. The revolving or circulating of the balls additionally provides for a constant movement and displacement of the vaporizing member, as a result of which there can be avoided striated or streaky flows which lead to a non-uniform or irregular formation of the fuel-air mixture.

Patent DE-3545648-A1 (DE)
Title: Air-conditioning wall with recovery of the ventilation heat from the air discharged from the room for pre-heating the air supplied to the room
Inventor: SAMERSKI LOTHAR DR ING
IPC: F24F12/00
Filed: 1985-12-21
Abstract: In order, in the case of exterior walls of heated and ventilated rooms, to recover not only the transmission heat, but also the ventilation heat, a ventilated facade is fastened in front of the house wall. A sheet separating the supply-airstream and discharge-airstream is located centrally in this air gap. Along this sheet, the discharged air transmits its heat to the supply air. In order that the heated supply air is not considerably cooled by the facade, the latter is heat-insulated. In order, however, to be able to make optimum use of the facade as a solar absorber, the actual facade is mounted such that it is separated from the insulating wall by an air gap. Before the supply air reaches the sheet, it flows through this air gap and absorbs the solar heat from the facade. The supply-airstream and discharge-airstream are produced in each case by a ventilator in the wall. In order that the wind pressure does not ventilate (cool down) the house in an uncontrolled manner when the ventilator is not in use, a double flap seals off both air ducts when the ventilator is not operating. The wind pressure does not produce any actuating force on the double flap.
Patent DE-3600634-A1 (DE)
Title: Method of carrying out light-dependent production process and apparatus for carrying out the method
Inventor: SCHIMMELPFENG LUTZ DR
IPC: B01J19/12
Filed: 1986-01-11
Abstract: The method of carrying out light-dependent production process is described, in particular a method for the mass production of photosynthesising organisms. The organism cultures are illuminated by light sources and the method invented is characterised in that the light source or the light sources is or are dipped into the organism reaction vessel. For this purpose, apparatuses are specified for carrying out the method in which the immersed light sources are designed as rod-like or else as spherical light sources. However, apparatuses can alternatively be used in which a combination of these two types of light source are used. In particular, a light source is proposed which comprises an optical fibre bundle, the individual optical fibres of which are fanned out in the interior of the reaction vessel and are prepared in such a manner in this fanned out region that the said optical fibres radiate light in a radial direction.
Patent DE-3604910-A1 (DE)
Title: Method of evacuating vacuum systems having a zeolite packing
Inventor: MAIER-LAXHUBER PETER DR
IPC: B01D53/28
Filed: 1986-02-17
Abstract: To evacuate a vacuum system having a zeolite packing, the zeolite packing is first heated and adjusted to a residual water loading between 7 and 0.5 % by weight. The zeolite packing is then evacuated in this state in the vacuum system under the previously prevailing water vapour partial pressure. In this case, water vapour on the zeolite is also removed by suction. The residual water loading decreases as a result. The heat of desorption necessary for this originates from the sensible heat of the hot zeolite packing. The water vapour flowing off entrains all the gases situated in the vacuum. The vacuum system is sealed to be air-tight under reduced pressure.

Title: Laser beam levelling instrument
Inventor: AMMANN HANS-RUDOLF
IPC: G01C15/00
Filed: 1986-10-23
Abstract: A piece of tube (6) is vertically supported centrally in the lid (4) of a housing (1). This piece of tube (6) can be rotated with its ends so that it can always be held in the perpendicular. For this purpose, two spirit level bubbles (8) are arranged at right angle to one another on or at a plate (7) attached to the lower end of the piece of tube (6). The fluid in these bubbles conducts the electric current and has electric contact points for operating in each case one electric motor (10, 11) per bubble. The electric motors are provided with eccentric shafts which come into contact with the circumferential surface of the piece of tube (6). If the piece of tube (6) deviates from the particular, the current of batteries ensures that the piece of tube (6) is returned to the perpendicular via the shafts. The laser light source is located in a lower part of the piece of tube (6). A further piece of tube is inserted into the upper end of the piece of tube (6), which carries a head (16) with window (17) and can be placed into rotation by a third electric motor (18). The laser beam arrives vertically in the head (16), is there deflected into the horizontal and emerges from the window (17) as a horizontal laser beam. <IMAGE>

Patent DE-3709306-A1 (DE)
IPC: H01H13/702
Filed: 1987-03-21
Abstract: In a press switch of a keyboard with a press key (11) which moves in opposition to a stationary switch part (3), electric leads (22) in the press key (11) run from contacts (25) arranged on the stationary switch part (3) in or on a flexible foil to connecting contacts (24) for an LCD display (14) arranged on the key (11). The foil (16) extends, together with the leads (22), into the printed circuit board (12). The foil itself constitutes the printed circuit board (12), which is provided with a compound-filled integrated switching circuit (23). This eliminates the need for cable connections for the foil inside the press switch. Preferably, the foil forms a loop between the switch part and the press key. The loop absorbs the movements of the press key with only slight bending, so that the transition between the foil and the printed circuit board is not subjected to high stresses and no damage occurs there.
