Patent EP-0275829-A2 (EP)
Inventor: KNOPF ULRICH CHRISTIAN DR
IPC: F25B21/02
Filed: 1987-12-17
Abstract: Apparatus for cooling and deep freezing samples of biological material. The cooling zone, containing the closed plastic vessels with the samples, is enclosed between two parallel, plate-like layered cooling elements. The latter are made of at least two cooling layers containing blocks of Peltier elements, alternating with plates of a heat-conducting metal, preferably aluminium. The disposition with several layers of Peltier elements increases the temperature difference between the inner space and environment. The innermost layer of the cooling elements is a metal plate as well; the outermost layer is a metal plate with means for external cooling, such as channels for circulating water or cooling ribs. The cooling zone is either a metal block with cavities to receive the sample vessels or simply the free space between the two innermost plates of the cooling elements, into which the vessels can be inserted. In one special design the metal block is an exchangeable module or cassette to be inserted into the cooling space. All parts, except the plates cooled externally, are thermally insulated; the cooling space is sealed against humidity by an insulated lid. The apparatus is controlled by a programmable electronic unit, by which a temperature program for the freezing process can be followed. The signals are given by temperature sensors in the cooling zone. In a preferred design, the freezing apparatus, the electronic control unit and the power supply are combined together in portable housing box.

Abstract: In an aerobic process for waste water (effluent) purification with intermittent batch feed of the waste water to the activated sludge tank from which the treated waste water is discharged continuously, the nitrate content of the waste water is simultaneously reduced by the aeration of the activated sludge tank, commencing with the flow of the waste water to the tank, being restricted to values corresponding to </= 0.5 mg/1 of dissolved oxygen, or in particular turned off, until the nitrate content in the tank has fallen below 5 mg/1 or, in particular, below l mg/1. In such treatment of communal waste waters, an approximately 1 hour cycle time is advantageous and the aeration, commencing with the rapid input of the waste water charge, is turned off for about 5 minutes. Suitable feed batches are </= 30% and, in particular, between about 5 and 20% of the tank contents. In this process, the nitrate content is reduced during the phase with oxygen restriction, while in the subsequent phase (over longer periods of time), the ammonium carried in with the waste water feed is converted into nitrate, it being advantageous to provide for an adequate nitric bacteria population in the tank.

Abstract: A sheet transfer cylinder is provided, as seen in the sheet- movement direction, between the printing cylinders of two printing mechanisms. This is followed by a sheet layer having an essentially flat laying surface roughly tangential to the sheet transfer cylinder. The sheet transfer cylinder pushes the guided sheet, with the free front edge of the sheet leading onto the sheet layer during the approach of the grippers holding the rear edge of the sheet. From there, the sheet is lifted again with the rear edge of the sheet leading by additional grippers on the sheet transfer cylinder. By this method of sheet-turning with the assistance of an essentially flat sheet layer, it is possible to achieve a low construction height for the machine, and the sheet-turning takes place reliably even with thick card. …<IMAGE>…

Abstract: The spring arrangement (7,31) coupling the flywheel elements (1,2) has a spring group (7) which operates with friction depending on the centrifugal force, so that the coupling of the flywheel elements (1,2) is stiffened at relatively high speeds. In consequence, an undesired flexibility of a drive train at the operating speeds is avoided. On the other hand, because of the flexibility of the spring group (7) at low speeds and low friction, a low resonant frequency is achieved, below the vibration frequencies occurring in the drive train at these speeds.

Abstract: A bump electrode structure of a semiconductor device comprises an electrode pad (13) formed of an alu­minum alloy, an insulating oxide layer (14) covering only the peripheral edge portion of the electrode pad (13), an under-bump layer (15) formed of an alloy of titanium and tungsten, and a bump electrode (16) formed of gold. The titanium-tungsten alloy functions both as a barrier metal and as a bonding metal. The bump electrode (16) rises substantially straight from the bonding surface of the under-bump layer (15), and its top portion has an area only substantially equal to that of the electrode pad (13). Fine V-shaped grooves (17) are formed on the top surface of the bump electrode (16) by anisotropic etching. Thus, the semiconductor device with fine electrode pad pitches is provided with a high-­reliability bump electrode structure which ensures suf­ficient bonding strength between internal and external electrodes.

Abstract: A current generating circuit for dividing a current (Dynamic Element Matching) in which a portion of a plurality of transistors constituting change-over circuits arranged therein is removed by weighting the operating periods of the transistors thereby greatly reducing the number of elements, particularly in the case where a large number of bits are processed. Since the number of bits which each current generating circuit can process can be increased, the number of elements can be easily decreased, so that a source voltage can be reduced when the current generating circuits are connected in multiple stages (in a vertical cascade). Transistors constituting switching circuits are connected in a Darlington configuration, thereby expanding the operating range (dynamic range) of the circuit.

Abstract: The invention relates to a filter bank for frequency-division demultiplexing and multiplexing of L-channel signals, consisting of L-type transversal filters (non-recursive filters, filters with a finite duration of the pulse response (FIR)), with complex-valued coefficients, for real-value input signals and with complex-value output signals or conversely, with a sampling rate which is reduced or increased by a factor of M at the output, the L-filters being implemented by cascading several filters, in which arrangement the sampling rate is reduced or increased by a factor of Mq in each cascade stage, and is characterised by the fact that, in each case, in the individual filter cascades preceding the same cascade stage, a complex multiplier is inserted which multiplies the complex-valued output signal of the filter of the preceding cascade stage by the complex sequence of a complex carrier oscillation. Such filter banks are predominantly used for multiplexing or demultiplexing for single FDM channels in transmultiplexers, for example in satellite engineering. The aim of the invention is a unification of the overall arrangement of the filter bank by reducing the plurality of different filters or different filter coefficients, respectively. An improved characteristic with respect to the design, test, production is achieved, and better possibilities for introducing redundancy (which is of particular importance in the satellite application). In many cases, a reduction in the computing effort is additionally achieved. <IMAGE>

Abstract: In an optical fiber connector in which each of two optical fibers (21-21) is terminated by a plug (40) having a passageway (41) for receiving an end portion of the optical fiber, eccentricity of one fiber end relative to the other is reduced by causing each optical fiber to be mounted in a specified orientation with respect to its associated plug passageway. In one embodiment, because the two cylindrical plugs which are used in the connector are derived from contiguous segments (111-111) of length of tubular stock, because the plugs are arranged so that the contiguous ends of the plugs before separation from the stock become the mating ends in the connection and because the plugs after separation from each other have the same rotational orientation with respect to each other as before, the predetermined orientation of the fiber ends in the plug passageways of the two adjoining plugs prior to separation of the segments from the stock reduces substantially any eccentricity which otherwise would be caused by the random mounting of the fibers in the associated passageways.
