Abstract: A system is provided for moving and processing workpieces having a baseplate element for providing a fixed horizontal framing element for the system, the baseplate having a central hole therethrough and a plurality of vertical passages therethrough with the vertical passages arranged at repeating intervals on the circumference of a circle having its center located within the hole. The baseplate element has a substantially flat upper surface in the proximity of the vertical passages. A plurality of individual workstations are attached to the bottom surface of the baseplate, with one station for each vertical passageway, and each ststion having an opening for receiving a workpiece which is aligned with its respective vertical passageway. A vertical center post extends above the upper surface of the baseplate with the center of the center post at the center of the circle defined by the vertical passages. A turret assembly is fixedly attached to the center post and rotatable therewith, the turret assembly for holding at least one workpiece, and preferrably a plurality of workpieces at a radial distance from the center of the center post that is equal to the radius of the circle defined by the vertical passages. An elevator system is used for moving the center post and turret means up and down between an uppermost position and a lowermost position. The lowermost position is located such that a workpiece would be fully inserted through any one of the vertical passages and into a corresponding one of the individual stations, and the uppermost position is located such that a workpiece would be fully withdrawn from any one of the vertical passages and out of the corresponding individual station.An indexing system is used to rotate the center post and turret assembly through angular elements which are multiples of the angular increment between the vertical passages relative to the center post. Thus as the center post and turret are lifted, indexed, and lowered, a workpiece is moved from one worksation to another, and in the case of a plurality of workpieces, the workpieces are moved simultaneously and incrementally from one workstation to another. A dome is sealed to the baseplate forming a main pressure vessel enclosing the center post and the turret assembly.

Abstract: A gas chromatography plus mass spectrometry system implements a scan strategy in which each full range scan alternates between a normal measurement mode and a survey mode based on a block/gap map made during the previous scan. Survey mode is used within regions that were determined in the previous scan to lack signal above a predetermined threshold. Spectral data is generated during measurement mode operation. Each scan serves both measurement and mapping functions in a way that avoids mass filter jumps, since each scan is monotonic over the entire scanning range.

Abstract: An audio transducer device capable of acting as a full range speaker which achieves the propogation of a peaked wavefront from the diaphragm instead of generating a substantially planar wavefront as in the case of the common speaker construction utilizing a diaphragm driven as a piston. The speaker has a frame with a central open area in which is supported a substan­tially planar, thin, flexible film forming the diaphragm. The diaphragm is driven by a driver which imparts motion to the diaphragm at a small source area preferrably centrally disposed of the diaphragm, the motion being imparted in a direction normal to the plane of the diaphragm so that ripples radiate from the drive area and travel at the same time across the flexible diaphragm, one behind the other, towards the frame. The drive area is small relative to the overall diaphragm and may be a point source or a line source. The rest of the diaphragm is driven by the central moving portion, endowing it with a built-in time delay, much in the same manner ripples move out in a still pond when a pebble is thrown into it. Because of the time delay involved in spreading the energy across the diaphragm, the wavefront radiated by the speaker gets a head start at the centre and lags towards the edges. The result is that of a spreading spherical wave front for a point source and a cylindrical wave front from a line source, and allowing a large diaphragm to behave as a small virtual audio source. This ensures excellent treble dispersion from a diaphragm capable of substantial bass response. In each case, the full range transducer requires no crossover, equalization or time delay circuits. The linear coil in the line source arrangement presents an amplifier with the ideal purely resistive load, with no substantial inductance or reactance. Similarly, the point source can be readily designed to present a simple load with only a mild inductive characteristic.

Abstract: A magnetic bearing with permanent magnets for absorption of the radial bearing stresses and with a stabiliser is specified for a rotor, which stabiliser holds the rotor in a position relative to the stator such that it does not make contact. Mounted on the stator for this purpose there are electric coils which interact with parts which can be magnetised but are fitted on the rotor. In order to render the bearing as independent as possible from the spatial orientation of the rotor axis and from deformation of the housing, in the region of the rotor centre of gravity (Figure 1, reference symbol 4) there is arranged a centre of gravity bearing (5) with a comparatively high radial stiffness and, at another point of the rotor 1, a stabilisation bearing (7) having a low radial stiffness in comparison with the centre of gravity bearing. The centre of gravity bearing (5) supports the majority of the rotor weight, the stabilisation bearing (7) essentially takes over the static and dynamic stabilisation of the complete system. <IMAGE>

Abstract: A programmable low noise frequency modulated signal source including a voltage controlled oscillator (VCO) having a frequency locked loop (FLL) constituting a first feedback path and a phase lock loop (PLL) constituting a second feedback path is provided. The PLL includes a VCO (11), a programmable fractional-N frequency division network (13) for changing the rational number by which the VCO output signal is frequency divided, a phase detector (15) for comparing the phase of the VCO output signal with the phase of a reference signal and for producing an error signal for controllably adjusting the output frequency of the VCO (11). The FLL includes a delay line frequency discriminator (10), a loop amplifier (33) and filter (31) to provide a first feedback signal to the VCO (11) to thereby reduce the phase noise on the VCO output signal. The frequency discriminator (10) includes a first signal path having a frequency sensitive time delay network (27) to provide a phase shift as a function of the VCO output signal frequency and a second signal path which includes a voltage controlled phase shifting network. The VCO tune voltage derived from the PLL phase detector (15) is coupled to an input terminal at the voltage controlled phase shifting network. The tune voltage adjusts the phase difference between the two frequency discriminator signal paths to set the operating point of the FLL phase detector (29) such that the VCO output signal will have a desired frequency. Since the PLL VCO tune signal is coupled to the control input of the voltage control phase shifting network (25) the FLL phase detector operates without an offset voltage at its output. Low   distortion frequency modulation of the (FM) VCO output signal is achieved by coupling an FM signal to the voltage controlled variable phase shift network (25).

Abstract: A novel method has been discovered for the preparation and application of a special vapourized mixture having therapeutical characteristics. This method has now been used for curing specific diseases in plant, human and animal cells by fully subjecting such affected cells to such vapourized mixture. This mixture is generated from a heated liquid, such as water, in which controllably a certain quantity of certain free gas particles e.g. hydrogen and oxygen is added, whereafter a chemical reaction takes place and a new material composition, specified as "Aquatilis", is created under simultaneous generation of heat. These free hydrogen and free oxigen gas particles with which the vapour mixture is enriched thereafter are kept in a state wherein diseased cell structures, are entirely and intensively surrounded by the "Aquatilis" mixture, and whereby during the treatment said mixture is kept in an enclosed space, e.g. a saunacabin (1). The mixture is kept at a predetermined elevated temperature by generating more free gas particles and maintaining in said space a predetermined vapour pressure, thereby forcing "Aquatilis" to attack e.g. chemical groups of socalled radicals which are considered to be found in certain diseased cell structures, thereby essentially and agressively supporting and augmenting the inner cellular offensive system energy against the presence of any noxious nuclei which affect the normal operational cell functions and destroying thereby such noxious nuclei entirely. The mixture has been successfully used to cure a.o. major diseases such as incurable multiple sclerosis, skin cancers and is believed to cure also patients from aids diseases.

Abstract: Such semiconductor valves are connected to a relief branch of a relief capacitor Cs and a diode Ds with a parallel resistor R for limiting positive overvoltages. When the current is commutated to the relief branch, a reverse current forms which can break off with a steep edge and lead to hazardous negative overvoltages. To relieve the valve with respect to these overvoltages, an auxiliary capacitor Cd is connected in parallel with the diode Ds. A saturable reactor Lk with a parallel resistor Rk is arranged in series with the semiconductor valve. <IMAGE>
