Abstract: A face seal is formed between a carbide seal ring 31 mounted in a stationary housing and a carbide seal ring 44 which is mounted on the shaft. A bellows provides a resilient bias holding the face 46 in engagement with the ring 31 and allows for lateral displacement of the shaft. A carbon ring 51 is a press or interference fit within the seal ring 44 and acts as a vibration damper. The carbon ring is longer than its radial thickness and has an axial extent somewhat less than that of the ring 44. It has a small clearance with respect to the shaft surface.

Abstract: A thermal transfer plate for removing heat to a heat sink or cooling fins positioned between an electrical component and a mounting surface. The plate comprises a heat conductive material which is in thermal communication with the electrical component and extends beyond the electrical component to establish thermal communication with a heat sink or cooling fins. In one specific embodiment, the thermal transfer plate has a base portion with upright side walls which form a socket to receive the electrical component. Horizontal cooling fins are located at the top of the sidewalls. The cooling fins can be of any shape which will perform the cooling or heat sink function and can be made with openings which permit air to circulate through the cooling fins. Moreover, due to its efficient heat transfer capabilities, the thermal transfer plate could be thermally connected to a separate heat sink device.

Abstract: To obtain enzymes from an enzyme-containing suspension such as, in particular, from untreated fermentation broth, the suspension is introduced together with granular material which is able to attach enzyme, such as, in particular, an ion exchanger material, into a vertical tube and a stream of inert gas formed, in particular, by dry nitrogen is passed through the mass at a gas velocity sufficient for fluidisation. During this the mass is mixed and solvent (water) evaporates until sufficient enzyme attachment to the granular material by concentration is achieved. The suspension residues are driven out of the mass, in particular by a pulse of compressed gas, and the attached enzyme is eluted. To speed up the process the stream of gas and/or the mass itself are preferably heated to temperatures tolerated by the enzyme. It is possible and preferable to carry out a washing step between the removal of the suspension residues and the elution of the enzyme, in which case the washing liquid is expediently passed to another fixed bed column with granular material able to attach enzymes. The elution can be carried out as stepwise elution. <IMAGE>

The structure is in the shape of a right circular cylinder with a plurality of internal cells (16, 22, 26) extending along the substrate and an opening on both ends. In order to provide maximum crushing strength of the structure, as well as permitting uniform intercell wall thickness at the downstream face of the extrusion die which forms the structure, the majority of the cells are formed in the transverse cross section of a truncated (circular) sector and have the property that they each possess the same hydraulic diameter, although not all are of the same transverse cross sectional shape. The extrusion is formed by a plurality of concentric, collared tubes (40, 50, 60) provided with longitudinally running slots (48, 58, 68) in the tubes and notches (44, 54, 64) on the collars (42, 52, 62), the tubes being radially spaced from each other. The non-slotted portions of the tubes define the cells of the extruded structure.

Abstract: 2.1 In the known methods for structural improvement by a melt treatment, sodium is introduced into molten aluminium in the form of sodium metal, salt, tablets or other refining agents in block form. In these cases, the refining agent decomposes only slowly and releases sodium to the melt over a prolonged period. In the same way as with the other melt treatment agents mentioned, sodium refining takes place under air over a prolonged period, so that burning of the reactive elements and pronounced oxide formation in the melt occur. 2.2 The making-up of liquid metal melts with reactive elements is to be improved in such a way that fine dosage becomes possible while avoiding oxide formation and a high burning rate. The method is characterised in that the element, or an alloy containing the element is converted into a liquid state and added under pressure to the molten metal underneath the surface. 2.3 The method is preferably used for making up reactive melts.

Abstract: In a digital echo canceller (EK) with residual-echo limiter (NLP), a threshold (Sa) is derived from the signal on the receiving path (EW), with which the level (PSWA) at the input of the residual-echo limiter (NLP) is compared. If the level (PSWA) is lower than the threshold (Sa), the path of the residual-echo limiter (NLP) is blocked. If not, it is opened. Since this threshold (Sa) is only derived for the echo passing via the adjacent hybrid, the residual-echo limiter (NLP) cannot respond to other echoes to the same receiving-path signal. Therefore, the rising total echo attenuation is measured from the beginning of a call and when a defined value is reached, the arrangement switches to a different threshold (Se) which is obtained by subtraction of the canceller attenuation (ACANC) from an artificial echo level (Py) which is derived from the digital filter (AFI) and a logarithmating unit (LG2). <IMAGE>

Abstract: Alignment problems are mitigated in connection with optical signal transmission and similar multiple path-supporting transmission media by the use of differential optical transmission. When the source signals are electronic, a complementary signal is developed electronically, and the signal and its complement are each applied to a light emitting device. The light of each of the light emitting devices is collimated with a lens and transmitted to a receiving lens. The two receiving lenses focus their respective collimated input onto photodetectors which convert the light to electronic signals, and the electronic signals of the two photodetectors are applied to a differential amplifier. The two lenses that transmit the signal and its complement for a transmitting pair, and the two lenses that receive the signal and its complement form a receiving pair. To utilize the advantages of this invention, the transmitting pair and the receiving pair need to be aligned with respect to each other so that each of the photodetectors receives approximately the same proportion of the transmitted optical signal of the two light emitting devices, respectively.
