Title: Sampling valve for a coal gasification plant having a fixed-bed pressurised reactor
Inventor: RICHTER ARTUR ING GRAD
IPC: G01N1/22
Filed: 1984-06-22
Abstract: The invention relates to a sampling valve for a coal gasification plant having a fixed-bed pressurised reactor, a liquid or gaseous sample being withdrawn by the sampling valve from the crude gas leaving at high temperature. In order to be able to control the operating conditions optimally, the composition of the crude gas must be able to be determined as closely as possible to the reactor outlet, despite the high temperature prevailing and a high condensable solids content possibly present at this point. In order to ensure this possibility, the sampling valve should be provided with a heater and/or flush cleaning, the heating counteracting condensation and the flush cleaning serving to remove condensation components occurring nevertheless.

Title: Circuit arrangement for recovering the clock from an intermittent pulse sequence
Inventor: ROEDER HORST-FRIEDRICH DR ING
IPC: H03L7/14
Filed: 1985-04-25
Abstract: It is intended to recover the clock from an intermittent pulse sequence, particularly for transmitting the digitised sound component signals in satellite television transmission, with the aid of a known phase locked loop, consisting of phase comparator 2, low-pass filter 5 and voltage-controlled oscillator 6, with adequate pull-in and locking range. For this purpose, a retriggerable monostable flip flop 3 with such a time constant that it remains continuously activated with correct spacing of the incoming pulse sequence and switches through a subsequent switching element inserted in the phase locked loop, is connected in parallel with the input of the phase locked loop. When at least one pulse sequence is missing, the monostable flip flop 3 returns to its idle state. The switching element controlled by it interrupts the phase locked loop with the consequence of maintaining the last control voltage present at the voltage-controlled oscillator 6. In the simplest case, the switching element is a tristate gate 4, inserted behind the phase comparator 2 and in front of the low-pass filter 5, the control input of which is connected to the output of the monostable flip flop 3. For more sophisticated requirements, a sample- and hold element 4a, the control input of which is also connected to the output of the monostable flip flop 3 and which is inserted behind the low-pass filter 5 and in front of the voltage-controlled oscillator 6 is used as switching element (Fig. 3). <IMAGE>

Title: Device for matching the lifting/force effect of an electromagnet to a desired lifting/force effect
Inventor: PAVLOVSKY RUDOLF DIPL ING
IPC: F16K31/06
Filed: 1985-05-21
Abstract: A device is proposed in the case of which the force effect of an electromagnet on a component, for example on a valve slide, is increased only when the component is starting to be lifted, by means of at least one lever. A lever (2) is inserted between the thrust bolt (3) of the electromagnet and the component (1). The lever (2) is supported at its supporting end (10) on a stop (9) which is at a distance from the thrust bolt axis (6a) and from the component axis (6b). The thrust bolt (3) touches the lever (2) at the supporting point (5) which is closer to the component axis (6b) than the supporting point (4) of the lever (2) on the component (1). This results in a force transformation ratio of i > 1, and the component (1) is moved with a greater force. In order to prevent lateral forces, it is advantageous to arrange a plurality of levers (2) uniformly or in mirror-image form with respect to the component axis (6b). <IMAGE>

Title: Extendable disk-stack cartridge, in particular for EDP installations, for recording electromagnetic signals
Inventor: PFEIFFER GUENTHER
IPC: G11B17/038
Filed: 1985-10-01
Abstract: The objective of the device is to increase the storage capacity of interchangeable data carriers, in particular for personal computers, by using in future instead of the conventional diskette, having only one magnetisably coated disk, a cartridge having a multiplicity of such disks, which lie one on top of the other in an orderly manner to form one or more stacks and can be telescopically drawn apart when the upper covering half of the cartridge is raised. The individual disks of a stack are connected to one another in such a way that the rotational movement of any one disk of the stack results in an identical rotational movement of the remaining disks of the same stack. This rotatably movable and liftable connection of the individual disks to one another is not relinquished at any time. During raising of the upper covering half, at the same time the disk stack or stacks stored in the cartridge is or are drawn apart and a previously closed access opening in the cartridge is opened to such an extent that, through this and the resulting interspaces of the individual disks of the stack, the magnetic heads can come into direct access with the tracks of the individual disks. Since the stack is telescopically drawn apart and pushed together again only in the drive by means of auxiliary elements and a corresponding mechanism, and since at the same time the cartridge is also closed, the possibility of contaminating or damaging the individual disks is eliminated.
