Title: Cartridge housing for a mixer valve
Inventor: PAWELZIK MANFRED DIPL ING
IPC: F16K27/04
Filed: 1986-02-26
Abstract: The invention relates to a special housing or cartridge for a water mixer valve with at least one valve seat disc held essentially immobile and a regulating disc which is supported on the valve seat disc, can be displaced with the aid of an actuating member and is held in sanitary fittings by means of fastening screws arranged parallel to the centre line, the special housing being formed by an approximately cylindrical, cup-like sleeve and a base part having openings for the passage of water. To reduce the outside diameter of the housing while keeping the dimensions of the valve discs the same, it is proposed that the outer side wall of the sleeve be divided by longitudinal slots intended to receive the fastening screws and that the base part have radially projecting noses which engage in corresponding recesses in the sleeve, and that shoulders to support the side wall of the sleeve be formed on the noses, preventing the sleeve from being bent open or deformed in the assembled condition.

Title: Liquid-cooled piston internal combustion engine, especially for motor vehicles
Inventor: KOLOSKA ECKARD DIPL ING
IPC: F02N19/10
Filed: 1986-03-20
Abstract: A liquid-cooled piston internal combustion engine, especially for motor vehicles, has coolant-washed cylinder liners in the cylinder block, the coolant flowing through the gap between the cylinder liners and the outer wall of the cylinder block and the coolant jacket being in direct contact with the walls of the cylinder liners. During the warm-up phase the coolant can be heated by exhaust heat. In the gap between cylinder liners and outer wall of the cylinder block a thin-walled sheet metal jacket is arranged in such a way that a first space, filled with coolant flowing through it, is formed between cylinder liners and sheet metal jacket and a second space, with no coolant flowing through it, between sheet metal jacket and outer wall of the cylinder block. Measures are taken to ensure that exhaust gas flows directly through the second space during the warm-up phase. By means of the abovementioned measures a significant reduction of the warm-up phase can be achieved in a simple, cost-saving way and without increasing the weight or volume of the engine.

Patent DE-3632967-A1 (DE)
Title: Sealing and coupling device
Inventor: LESCHNIK NORBERT
IPC: F16L29/04
Filed: 1986-09-27
Abstract: The sealing and coupling device consists of two coupling halves (1) and (2), each having a valve. In the case of the first coupling half (1), the valve comprises a sleeve (8) which protrudes beyond a housing (3) of the coupling half (1) and can be displaced into the housing (3) counter to the action of a spring (7). In the case of the second coupling half (2), the valve comprises a piston (26) with axial holes (23) and a stud (30) which projects beyond a housing (4) of the second coupling half (2). To couple conductors connected to the coupling halves (1) and (2), all that is required is to bring the coupling halves (1) and (2) close enough together, without the need for them to be arranged coaxially. All that is required is that the sleeve (8) of the first coupling half (1) should rest leaktightly against the second coupling half (2), whereupon, as the coupling halves (1) and (2) are brought closer together, the sleeve (8) is moved deeper into the housing (3) and, as a result, the valve of the first coupling half (1) is opened. If the movement of the coupling halves (1) and (2) towards one another is continued, the piston (26) of the second coupling half (2) is also pushed deeper into the housing (4) by the stud (30) with the result that, finally, the valve of the second coupling half (2) is also opened. <IMAGE>

Title: Simultaneous SO2/NOx wet scrubbing process with scrubbing water treatment for purifying combustion exhaust gases
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/60
Filed: 1986-12-02
Abstract: Processes are known for purifying SO2 and NOx from combustion exhaust gases by use of a wet circulation scrubber with scrubbing water treatment, the scrubbing water of which contains iron(II)-EDTA or iron(II)-NTA complex. In order to be able to carry out a process of this type having technically improved results and lower expenditure, according to the invention it is proposed that the simultaneous wet scrubber is operated on an alkali basis (sodium) and the additive addition is hydrated lime. In the scrubber (2), the untreated gas (1) is scrubbed with scrubbing water circulated via a pump (3) and pipe (4) and, freed from the pollutants dust, HCl and HF, leaves the prescrubber (2) and, via the demister (18), enters the SO2/NOx simultaneous scrubber (5). Here, the prepurified flue gas is freed from sulphur oxides and nitrogen oxides by a scrubbing solution which is circulated via a pump reservoir (6) of a pump (7) and pipes (8). The flue gas leaves the scrubber (5), purified, at (14). <IMAGE>

Patent DE-3711838-A1 (DE)
Inventor: SCHUMACHER ERNST
IPC: G03F5/00
Filed: 1987-04-08
Abstract: The invention described comprises an optical screen with which the required copies can be produced by using the photomechanical process of printing form production. Printing forms of the type forming the subject of the invention can be used advantageously for all printing processes since the printing or non-printing surface components of the screen elements, which are of various sizes depending on the tone value, are designed with differing geometrical shapes which are specific both for the printing process and also for the tone value to be reproduced. In letterpress and offset printing, the printing forms according to the invention enable a very uniform progression of the overall tone scale; this effect is due in particular to the fact that the transition from connected to unconnected printing screen elements is achieved by a structure of escutcheon-like screen elements which is characteristic of the invention. In addition, the highlights are effectively emphasized by a deliberate reduction in dot frequency in the high-light zones. With the letterpress printing forms according to the invention the ratio of dips to land is improved; the land is stabilized.

Title: Solenoid valve with flow through the interior
Inventor: KAES GUENTER
IPC: F16K31/06
Filed: 1987-07-14
Abstract: A solenoid valve for brake systems or the like with flow through the interior is proposed, in which an armature actuable by an annular magnet coil can be held in a deenergised open position or a deenergised closed position. The armature is of sleeve-shaped design and surrounds the valve element arranged concentrically to the axis of flow through the solenoid valve. An actuating element formed on the armature engages on the closing element and it is a simple matter to design the solenoid valve as a valve which is open when deenergised or closed when deenergised depending on the design of the actuating element and of a spring element actuating the armature. <IMAGE>

Title: Power supply unit having a switched, saturated inductor
Inventor: MANDL PETER DIPL ING
IPC: H02M3/28
Filed: 1987-08-18
Abstract: A method for stabilising a DC voltage by means of a switched, saturated inductor. The method relates to the stabilisation of a DC voltage which has been produced from an unstable AC voltage, which is characterised by an on-phase and an off-phase, by rectification, averaging and the assistance of a saturated inductor. The inductor is connected in series with the AC voltage source and controls the power flow from said source to the load by a specific, unsaturated magnetisation state being impressed on it at the start of the on-phase in order that the load current to the load, which occurs with saturation of the inductor, is delayed in a metered manner. Known methods adjust the unsaturated magnetisation state with relatively high losses in the actuating element. According to the invention, the magnetisation state of the inductor at the start of the on-phase is brought about in an objective manner and with low losses in that said inductor is demagnetised virtually down to the desired value during the off-phase via the same circuit which carries the load current, and is short-circuited from this point in time to the end of the off-phase, in order to maintain the magnetic field. The method is used in the case of switched power supply units (switched-mode power supplies) for stabilisation of the unregulated outputs.

Title: Method for separating heavy liquids from wastewater
Inventor: WEILER WALTER DIPL ING
IPC: B01D17/02
Filed: 1987-11-27
Abstract: The novel process for separating liquid, especially highly dispersed residual contaminants, whose density is greater than 1 (heavy liquid) from wastewater (effluent) consists in the wastewater to be treated (purified) being subjected to a coalescence process, and the coalesced residual contaminants being collected downstream of the coalescence stage and being drawn off, with the aid of gravity. Preferably, the heavy-liquid dispersion is subjected to hydrodynamic coalescence in a coalescence stage which consists of an open-pored structural foam (self-skinned foam, integral skin foam). The separated heavy liquid is preferably allowed to partly overflow into the packing of the coalescence stage, so that the inflowing wastewater is forced to flow through it.
Patent DE-3744162-A1 (DE)
Title: Time switch
Inventor: ROESCH JOHANN-GEORG
IPC: G04G19/00
Filed: 1987-12-24
Abstract: A time switch which is controlled by a microcontroller, has one or more floating switching outputs, is supplied with the necessary intrinsic energy from the AC mains power supply via a capacitive bias impedance and has a simple electronic circuit to control the DC voltage for the intrinsic energy, which electronic circuit is designed such that the power loss, which is converted into heat, is always a minimum, irrespective of the instantaneous power consumption. This is achieved in that the terminating impedance of the capacitive bias impedance is either virtually zero ohms or is the high input impedance of the downstream electronics, so that the current/voltage product is always in the vicinity of one of the minima. <IMAGE>
