Abstract: A mechanism for keys for keyboards consists of a key (1), which is pivotably mounted about a mounting (6), and a rubber bubble (3) arranged under the key (1). The rubber bubble has a conductive block (4) and is a part of a rubber mat laid on a circuit board (5). When the key is depressed, the block (4) first will touch a contact point (7a) on the circuit board (5), and for continued depression it will touch a second contact point (7b). There is thus obtained a positive contacting function when both contact points (7a, 7b) are bridged by the block (4).

Abstract: A controllable distributing conveying system for transporting people or goods is provided with stations which are arranged on a passive rail network and which include container loading-on positions, container off-loading positions, and container depots. Self-propelled controllable conveying units are movable between the stations and are fitted with pairs of running wheels for normal travel and for travel when being switched in and out and also have container-carrying surfaces separate from the drive section which are coupled by a universal joint member. Containers are loadable onto and off-loaded from the conveying units by means of loading and off-loading arrangements which have active locking members and unlocking members. These containers are held secure in all directions during travel, and are conductable to their destination by the shortest path by means of passive switching-in and switching-out arrangements, and these latter arrangements comprise rails, which the conveying units hold onto. In operation, at the time when the switching-out operation is to take place, the running wheels of the conveying units, intended for switching-in and-out travel, take hold on the switching-in or switching-out rails on the inside, the normal spacing of these rails being altered to the different spacing of the switching-out arrangement by curving the rails to this altered spacing, as a result of which the switching-in or switching-out wheels are forced to engage with switching-in and switching-out rails running parallel to the main rails.

Abstract: A heating device fed with free-flowing fuel and connected to an on-board voltage source, in particular, a vehicle heater. The heating device is equipped with a burner assembly which has a fuel supply, a combustion air fan and a heating element which ignites a fuel/air mixture after a preheating phase. During the preheating phase, the combustion fuel fan is shut off or at least is operated at less than the operating blower output. There is also a switching device which automatically turns on or switches the combustion air fan to its operating blower output after a preheating phase has been completed. The switching device is designed as a voltage-dependent time-function element, which presets a preheating time dependent upon the magnitude of the on-board voltage and which decreases the preheating time as the on-board voltage increases.

Abstract: Method and arrangement for varying a d.c. voltage occuring between electrodes of an electrostatic dust separator, said voltage being generated by a number of frequency-related pulses together forming a pulse train. A mains voltage (50 Hz) is fed via valve organs (8, 8a) controlled by a control circuit (7) to a transformer (T), the current pulses of which are full-wave rectified (9) and are connected to electrodes (10) of the dust separator. The control circuit (7) is so arranged as to extinguish an even number, being two, four or more, of pulses from the mains voltage between two consecutive pulses supplied to the electrodes of the dust separator.The control circuit (7) is also so arranged as to regulate the number of extinguished pulses and/or the pulse form of the individual pulse, so that with each pulse that is transferred to the electrodes there is also transferred to the filter that quantity of energy which is the maximum possible without producing flash-over or reverberation, in addition to which the control circuit (7) must be so arranged as to minimize the energy supply by controlling the length of the period between two consecutive pulses and by making this period as long as possible in relation to a limit value allocated to an opacimeter or similar.

Abstract: The relative electrical charge of a cell or organ unit can be affected by capacitive connection between the interstitial fluid in an organ area and a differently charged capacitor. An electrode introduced into this fluid and connected to earth, which is a reference for determining the tissue potential activates the relative voltage over the cell membranes and the voltage of the organ in relation to others. - This effect occurs slowly with earthing but can be rendered more effective by introduction of a voltage source between earth and the tissue. This can give either a positive or negative voltage in relation to earth. The capacitive charge movement between terminals gives rise to a variation in the conditions for ion pumping over the cell membranes. Thus, it is possible to affect the ion transport by voltage blocking and thus even affect the voltage gradients between the electrode tissue ambience and the voltage in the organ outside the affected tissue.

Abstract: A novel copolymer resin which has excellent tackifying properties for selected elastomers useful in hot melt and pressure sensitive adhesives is produced by the copolymerization of beta-pinene with other terpenes or hydrocarbon monomers, followed by thermal catalytic isomerization of the resin produced. Typically, beta-pinene and styrene (80/20) are copolymerized at a temperature between 0 DEG  to 60 DEG  C. under anhydrous conditions with a Lewis acid catalyst in a solvent. After catalyst removal, the copolymer resin is isomerized with iodine as a catalyst at a temperature between 200 DEG  to 260 DEG  C. Excellent yields of high softening point tackifier resins are produced.

Abstract: The present invention relates to a device and a method for a telecommunication system comprising an exchange (1), which comprises a network connection device (6), which provides a user (A) with the possibility to connect a computer (12) to a data network (3), as well as a telephony server (7), which provides said user with the possibility to, during an ongoing data network session, use the service telephony on the same subscriber line (14), which is being used for the data network connection. The invention makes the handling of user information in the exchange (1) more efficient, by providing the network connection device and the telephony server with user information, which is entered in one single user data base (10). The data base is used for operation and maintenance personnel entering static user information and for entering session related user information, which is obtained during one single access control at connection to the data network (3). The information in the data base is accessible to both the network connection device and the telephony server, which makes a second access control, when activating the service telephony during an ongoing data network session unnecessary. The present invention decreases the amount of duplicated user information in the exchange and makes handling of user information in the exchange easier.
