Patent EP-0224656-A2 (EP)
Inventor: KNAUER KARL
IPC: G06F7/50
Filed: 1986-08-25
Abstract: A multi-digit carry ripple adder in CMOS technology and having two types of adder cells, in which an inverted carry input signal (Cin) is in each case applied to the adder cells of a first type (I) and a non- inverted carry input signal (Cin) is in each case applied to the adder cells of a second type (II) and in which a non-inverted carry output signal (Cout) is in each case output by the adder cells of the first type and an inverted carry output signal (Cout) is in each case output by the adder cells of the second type. The gate arrangements in each case required are formed in such a manner that the charging of the capacitance of the carry output occurs either via only one transfer transistor 117' or 118' acting as transfer gate or via the series circuit of only two transistors, one of which is in each case contained in gates IIl, II2 (or 13,14) and the second is in each case formed by a transfer gate 117 or 118. Due to the different carry paths, both the binary value "0" and the binary value "1" can be transferred without additional off-state losses. The transfer transistors (7,7',8,8') are not a component of a combination gate within the gate arrangement so that they can be designed to be of lower impedance than the remaining gate transistors.

Abstract: A cartridge (20) for a drinking water treatment apparatus which does not employ pressure has a gravity-flow housing (22) filled with a treatment material such as ion exchange resin and/or active carbon and, optionally, a bacteriostatic substance. The upper and lower end walls (24, 26) are inclined with respect to the horizontal and each contain a multiplicity of narrow slits (34, 36) which likewise run at an angle with respect to the horizontal. This achieves the result that air bubbles bubble along the slits to their higher ends, the main part of the slits remaining free for the passage of the water. <IMAGE>

Abstract: New crosslinked polymers are prepared from a combination of starting materials comprising a polymer, a crosslinking agent for the polymer, and a conductivity agent containing a quaternary ammonium moiety. The conductivity agent contains at least one functional group which, during an otherwise typical process of crosslinking the polymer through the crosslinking agent, reacts to bond the conductivity agent covalently and pendently to the crosslinking agent or the polymer. The resultant crosslinked polymer has lower electrical resistivity due to inclusion of the conductivity agent.

Abstract: A spindle which has differential gearing and a change-over coupling. The speed can be changed by the differential gearing. The speed between the one and the other shaft of the coupling remains either 1 : 1 or is, for example, increased when the differential gearing is engaged. In the other operating direction of the spindle, the speed is accordingly reduced. Of the differential gearing, one gearing member (22) is arranged in a housing (2) of the spindle in such a way as to be fixed in terms of rotation. In each of its two end positions, an adjustable coupling part (12) produces a torque- transmitting connection, and in fact in its first end position directly between the two shafts (6, 10) and in its second end position between one shaft (10) and a gearing member (30) of the differential gearing. The differential gearing is preferably designed as epicyclic gearing (24) and has gears (22, 26, 28) as gearing members. The outer gear (22) of the epicyclic gearing is attached in the housing (2) in such a way as to be fixed in terms of rotation. At an appropriate setting of the coupling, the planet carrier (30) transmits a torque. <IMAGE>

Abstract: An electrical installation apparatus is shown and described, such as a switch, key, socket or the like, having an apparatus insert with a supporting ring (19), an operating and control element (e.g. socket insert 22) and an essentially frame-shaped cover (26). In order to use this installation apparatus in railing channels (10), the operating and control element (e.g. socket insert 22) can be supported on an adaptor ring (20) which can be connected detachably to the supporting ring (19), the adaptor ring (20) for its part being fitted with holders onto which the cover (26) latches such that it can be detached again. Furthermore, the cover (26), which is placed on the cover plate (12) of the railing channel (10), is kept flat such that its external projection surface seals in an essentially flush manner with the external projection surface of the functional element, while the supporting ring (19) of the apparatus insert (17) remains underneath the inner side of the fitted railing channel cover plate (12). This ensures that there is no need to use special cover plates (12) or cover plate sections with prepared holes. Instead, it is adequate to introduce the desired cut-out into the cover plate with a circular saw or a fretsaw on the site where the installation apparatus according to the invention is to be fitted. <IMAGE>

Abstract: A heater device for a motor vehicle comprises a fuel burner (4) supplied with combustion air by a blower (2), and a heat exchanger (5) for transferring heat from the combustion gas from the burner (4) to heating air which is drawn through the heat exchanger by a blower (13) and is then introduced into the passenger compartment of the vehicle. To prevent the heater device overheating when the engine of the vehicle is switched off thus stopping the blowers (2,13), sensors (32,34) detect the temperature within the heat exchanger and the burner and a sensor (33) detects the temperature of the air from the heat exchanger. Also a flame sensor (31) detects whether the burner is alight or not. These sensors send signals to a main control unit (9), and, if the temperatures sensed reach a prescribed limit, the controller switches the blowers on again by means of a switch (194) to introduce cooling air to the burner and the heat exchanger and thereby prevent the burner and the heat exchanger from being overheated.

Abstract: In the device suitable for using water lacquer or any other similarly conductive coating material, the paint particles are sprayed off the earthed spraying edge of a bell-type atomizer (2) and charged up in the corona discharge region of outer electrodes (10) which are inserted in a mounting arrangement (11, 12, 15) made of insulating material. Potential control means in the form of expediently chosen insulating materials used in the mounting arrangement (11, 12, 15) and/or in the atomizer housing (4) make it possible to approximate the radial potential pattern between the atomizer housing (4, 6) and the outer electrodes (10) to the radial potential distribution of the sprayed material. According to another aspect of the invention, the insulating material of at least one part (4, 11, 15) of the device consists of a fluorinated hydrocarbon such as PTFE. Both measures reduce the risk of self-coating of the device.

Abstract: 1. Check valve. 2.1 Known check valves have the disadvantage that, during their production, when the valve seat plate is riveted to the throw limiter, the riveting pegs break, as a result of which costly quality assurance test procedures are required. This disadvantage is avoided with the new check valve. 2.2 The new check valve is characterised by the throw limiter being designed as a single-piece valve limiting plate, in the form of a flat ring, made from diecast metal. During assembly, the valve limiting plate, leaf spring and valve seating plate are inserted one after the other into the valve housing and are connected to one another by rolling in the upper valve housing rim. 2.3 Such check valves are used for the reduction of hazardous substances in the exhaust gas of internal-combustion engines. <IMAGE>
