Abstract: The invention relates to a voltage controlled planar oscillator having a microwave transistor as the active component and a frequency-determining switching network connected thereto, which contains a varactor diode and a dielectric resonator. To be able to integrate such an oscillator monolithically on as small a chip as possible, it is proposed that the dielectric resonator is coupled to the switching network via a first microstrip line and that the microwave transistor is connected to one end of the first microstrip line with a first one of its three gates via the varactor diode. <IMAGE>

Abstract: A screw cap contains, on its cylindrical outer wall, a grooving which continues into the outer annular region of the lid section. The grooving consists of lamella ribs each having a slightly inclined long side and a short side which lies in a plane lying around the longitudinal mid-axis of the container closure. An outer cap which can be fitted onto the screw cap has a lid section which is convex relative to the screw cap, is supported centrally on the lid section of the screw cap, and can be deformed elastically into an approximately flat alignment by applying axial force. During this process, projections moulded onto the inner side of the lid section of the outer cap engage in the grooving of the lid section of the screw cap so that a torque can be transmitted in the opening direction. In the opposite direction of rotation, the outer cap is connected by end faces of an annular shoulder to projections of the screw cap. The screw cap can be used as a single closure or in combination with the outer cap as a child-resistant pressure/rotary closure. <IMAGE>

Abstract: A packet transmission system (100) with reduced transmission delays includes a communications controller (110) and a plurality of remote requesting units (112) requesting packet transmission services. Each remote unit (112) sequentially stores transmitted access requests (302) in a memory queue (500) and awaits a resource grant (306) from the communications controller (110). Upon receipt of a granted resource the remote unit (112) will apply the granted resource to the oldest request (502) stored in the queue (500) in order to transmit data (310) to the communications controller (110). 
     A separate and distinct aspect of the transmission system (100) resides within the communications controller (110). In response to the receipt of a data packet (310) from a remote unit (112), the communications controller (110) identifies missing data within the data packet transmission, determines whether communication resources are available to support retransmission of the missing data, and if so, transmits a response to the requesting remote unit identifying the missing data and simultaneously granting sufficient resources for retransmission of the missing data.

Abstract: The technical field of the invention is the filling and draining of a solar collector 3 which is filled with water and in which frost damage should be prevented from occurring. For this purpose, it is proposed to initiate and carry out the emptying solely by the force of gravity, the piping 8c leading to the solar collector 3 and the piping 9c returning from the solar collector 3 being connected V3, V4 in each case via a junction 20, 21 to a common collection container 11. Prior to emptying, by mixing in Mi, 8a warm water or by mere recirculation 2 in the solar collector circulation 8b, 8c, 9c, 9b, Z, Mi, any (necessary) emptying can be delayed and possibly avoided. Following an emptying operation, the solar collector can be filled again by means of a pressure generator 10, M, Pd, the heat transporting medium being pumped into the collector 3 via one of the said piping systems 8c, 9c, and the pressure thus arising corresponding approximately to the stationary operating pressure of the solar collector piping system 8a, 8b, 8c, 9c, 9b, 9a. <IMAGE>

Abstract: This invention relates to a method and apparatus for electrically testing a multi-core cable. A plurality of cores of the multi-core cable are connected at a first end (1) and are isolated from one another at second end (2). The cores are engaged at the first end with grooves formed on a movable member one by one so as to be picked up and are sequentially transported toward an electrode (22). The picked-up core is cut during its transportation so as to be electrically separated from a collective conducting part (10) at the first end. The picked-up core is charged to a high voltage through the electrode and based on a characteristic of its charging current a judgment is made about whether there is a defective contact between the picked-up core and other cores. Further, the electric charge of the picked-up core is discharged, the picked-up core is recharged, and based on the characteristics of these discharging and charging currents a confirmation of the above judgment is made. After the charging, judgment, discharging, recharging and judgment confirmation, the movable member is moved again to transport the picked-up core to safety discharge electrode (23).

Abstract: A method and apparatus (10) for burning a fuel in the presence of an oxidant in which intermixing fuel and oxidant jets (18,20) are formed from fuel and oxidant flowing in a mixing layer. The fuel and the oxidant are combusted to produce a projected flame (22). Intermixture of the fuel and the oxidant jets (18,20) occurs within a turbulent flow regime where the fuel and the oxidant are in close contact with one another within eddies. The fuel and the oxidant are intermixed in average stoichiometric proportions and the mass flow rates of the fuel or the oxidant or both are intermittent and have a regular pulsation. This regular pulsation has a sufficiently high frequency that the eddies contain the fuel and the oxidant in fuel-rich and fuel-lean ratios in an essentially even distribution through the projected flame. As a result a plurality of fuel-rich and fuel-lean regions are created throughout the projected flame and thermal NO x  and carbon monoxide emissions are reduced. Fluidic oscillators (24,26) are used to induce the pulsations in the mass flow rates since for most burners frequencies above 100 Hz are required.

Abstract: The area covered by a GSM base station can be increased in concentric rings of 35 km width by co-locating as many GSM transceivers as there are rings, the receivers of the transceivers being delayed by an amount equivalent to the round trip transit time for signals to transverse the inner rings. 
     To enable idle mobiles to access the system each transceiver includes additional auxiliary receivers to receive access bursts on the frequencies of the other transceivers. Thus a mobile can access the system irrespective of the cell in which it is located even though it does not know in which cell it is located.

Abstract: A method for fabricating semiconductor substrates with resistivity below 0.02 ohm-cm is provided. This low resistivity is achieved by doping a silicon melt with a phosphorus concentrations above 1 x 10 18 . The silicon melt is also doped with a germanium concentration that is 1.5 to 2.5 times that of the phosphorus concentration and a stress and dislocation free crystalline boule is grown. Phosphorus in high concentrations will induce stress in the crystal lattice due to the difference in the atomic radius of silicon atoms versus phosphorus atoms. Germanium compensates for the atomic radius mismatch and also retards the diffusion of the phosphorus as the diffusion coefficient remains relatively constant with a doping of 1 x 10 18  to 1 x 10 21  atoms per cm  3 . This will retard phosphorus from diffusing into an overlying epitaxial layer and retard other layers formed on the substrate from being auto-doped.
