Patent EP-0342155-A2 (EP)
Inventor: KNOPF ULRICH CHRISTIAN DR ING
IPC: F25B21/04
Filed: 1989-04-28
Abstract: The invention relates to a handy laboratory device for optional heating or cooling of samples. The thermal element used is a block of one or more Peltier elements, which can be used for cooling or heating by reversing the direction of flow as desired. One pole of the Peltier elements is in thermal contact with a metal block; the opposite pole is thermally connected to a heat exchanger. The metal block, provided with a horizontal working surface which can be heated or cooled, is separated by an insulation layer from the heat exchanger and also protected by an insulation jacket on its outer surfaces which are not used. The containers with the samples which are to be heated or cooled can, if appropriate, also be accommodated in exchangeable working modules which are provided with matched openings and which have a flat contact surface which is to be placed upon the working surface. …<??>The device consists of three mutually separate parts, namely the actual heating and cooling block, the modules for taking the sample containers and the electrical feed and control unit. The latter includes a switched-mode power supply unit for feeding the Peltier elements and an electronic control section which can be connected, if desired, to a microcomputer for the programming of temperature cycles. …<??>The heating and cooling device is suitable on the one hand for work in a biological, biochemical and genetic laboratory, where temperature cycles frequently have to be operated which are partially above and partially below room temperature, and on the other hand also outside the laboratory, for example for work on or transport of temperature-labile samples in mobile units such as, for example, in cars, railways and aircraft. …<IMAGE>…

Abstract: In the method for networking computers and/or computer networks, the occurrence of an interruption in the network system is determined and a redundant connection, which is inactive during undisturbed operation, is activated as a function thereof. The determination of an interruption takes place by testing whether a data signal occurs within a predetermined time interval on both the terminals of a redundant connection device (40) which are connected to the networking system. Various criteria are provided in order to interrupt a closed connecting ring, produced by activation of the redundant connecting device (40), when the original disturbance in the network system has been removed. Network systems and a circuit arrangement for carrying out the method are specified.

Abstract: A process and a device for filling by vibration in a pasting bath electrodes with welded-on current lead tabs are described. A retaining tool, which is connected to a vertical rotating shaft, supports the electrode and a reflection body arranged above it, and immerses said electrode into the pasting bath. After filling of the electrode support has been completed, the retaining tool moves said support, and the reflection body back out of the pasting bath. Subsequently, the excess paste is spun off the electrode support by rotation of the vertical rotating shaft above the pasting bath, the reflection body also being cleaned of the paste. The vibration oscillations emerging from the base of the pasting container are reflected in the paste by the reflection body, as a result of which the fluidity of the pasting bath is increased in the vibration field and the electrode support is filled quickly and more completely.

Abstract: Methods for amplifying and detecting a predetermined target nucleic acid in a biological specimen are known, and can be accomplished even when there is a mismatch in a single position between a primer and the target nucleic acid. The mismatch is located at or near the 3′ end of the primer. Disclosed herein is a method for overcoming such a mismatch, and is particularly useful for detection of a nucleic acid sequence which is not fully known, or where there is considerable heterogeneity in DNA target from patient samples. The method is characterized by using a primer having a nucleotide with a thymine base at the position of the mismatch, the primer being used to prime the target and to form primer extension products.

Abstract: A beam steering module (16A) rapidly applies control signals to a plurality of digital phase shifters (14₁ ... 14₄) in a phased array antenna system. The module (16A) can receive and store a plurality of phase shift commands for the phase shifters. The commands may be quickly applied to the phase shifters, (14₁ ... 14₄) to rapidly steer the beam from the antenna array, from storage in a bank (104) of registers. Individual commands are selected by a multiplexer (106) and applied by a buffer/driver (108) through a bus (110). The multiplexer (106) is controlled by a steering logic (32) that receives steering commands from a controller (20) controlling a plurality of beam steering modules and supplying phase shift command words over a data bus (D) to each module. Such words are first stored in a temporary register bank (102) so that reception of a new set of words does not interrupt the use of the storage register bank (104).

Abstract: A log periodic antenna array, each consisting of e.g. five dipoles D1 - D5 are each driven by a transmitter Tx by an amplifier A and phase shifter 5. Each antenna radiates generally from one dipole only for example dipole D4. The Applicants have discovered that the antenna may behave as if the radiation appears to emanate from the position marked with a cross. Probe antennas P1 - P3 are used to derive error signals representing the difference between the expected relative phase between a dipole and a probe antenna and the measured relative phase between the dipole and the probe antenna, which error signals are then used to apply corrections to the phase shifters PS.

Abstract: An antenna (10) incorporating a slot (12) and a plurality of ear-like dipole elements (13a,b). The antenna comprises a ground plane (11) having a slot (12) disposed therein, and a plurality of ear-like elements (13a,b) attached to one side of the ground plane along the elongated edges of the slot (12). The ear-like elements (13a,b) are oriented orthogonal to the ground plane (11) in the same direction. Typically, the plurality of ear-like elements are disposed in a symmetrically opposed relationship along the elongated edges of the slot. The plurality of ear-like elements typically comprise two generally quadrant-shaped elements having the centers of the respective quadrant-shaped elements are disposed at or near the outer edges of the slot and the outer edge of the elements extend to about the middle of the slot. The ear-like elements may be rotated with respect to the slot in order to fine tune the polarization direction. In a typical antenna, a plurality of slots are employed, and the present invention permits the use of randomly oriented or regularly spaced slots that are fed by means of conventional rectangular waveguides or boxed stripline. An polarized radiation field having a controlled arbitrary polarization is selectively produced by controlling the relative positions of the slot and ear-like elements. Typically, if all the energy radiates from the ear-like elements, then tile antenna is polarized along the slot. If all the energy radiates from the slot, then the antenna is polarized across the slot. When both the slot and ear-like elements radiate energy, then the antenna is linearly polarized if both the slot and ear-like elements radiate in phase, circularly polarized if both the slot and ear-like elements radiate with equal amplitude and the phase difference between them is ±90 degrees, and elliptically polarized if the excitation amplitude and phase associated with the slot and ear-like elements are not the same.
