Patent EP-0270666-B1 (EP)
Inventor: TENNENT HOWARD G
IPC: B32B9/00
Filed: 1987-06-05
Granted: 1996-08-28
Abstract: A discrete carbon fibril characterized by a substantially constant diameter between about 3.5 and about 70 nanometers, length greater than about 5 times the diameter and less than about 100 times the diameter, an outer region of multiple essentially continuous layers of ordered carbon atoms and a distinct inner core region. The invention further concerns a plurality of such fibrils. The fibrils of this invention may be produced by contacting for an appropriate period of time and at a suitable pressure a suitable metal-containing particle with a suitable gaseous, carbon-containing compound, at a temperature between about 850 DEG C and 1200 DEG C, or by treating discrete carbon fibrils, characterized by a length greater than about 100 times the diameter. Carbon fibrils may also be continuously produced by continuously contacting for an appropriate period of time at suitable conditions. Another aspect of the invention concerns a composition of matter comprising a carbon fiber or a carbon plate and a plurality of fibrils. Carbon fibrils and compositions of matter comprising carbon fibrils are useful in composites having a matrix of e.g., an organic polymer, an inorganic polymer or a metal. In specific embodiments, the fibrils or the compositions of matter may be used to reinforce a structural material, to enhance the electrical or thermal conductivity of a material, to increase the surface area of an electrode or capacitor plate, to provide a support for a catalyst, or to shield an object from electromagnetic radiation.

Granted: 1993-12-29
Abstract: Une cellule solaire à l'arséniure de gallium (6) possède une couche fenêtre à l'arséniure de gallium aluminium (20) dans laquelle des lignes de contact métalliques fines (40) s'étendent au travers de la fenêtre à l'arséniure de gallium aluminium (20) pour faire contact électrique avec la couche émettrice (14), et une pluralité de lignes d'une grille métallique (50) disposées sur la couche fenêtre (23) traversent les lignes de contact, faisant ainsi contact électrique avec les lignes de contact métalliques (40). Une bande métallique plate (60) s'étendant le long d'un des bords de la cellule solaire effectue la connexion électrique des lignes de la grille (50) entre elles. En conséquence, deux métaux séparés peuvent être utilisés, l'un ayant de bonnes propriétés de contact ohmique pour les lignes de contact métalliques (40) et l'autre ayant de bonnes propriétés de conduction de courant et d'adhésion pour les lignes de la grille métallique (50). De plus, les lignes de contact métallique (46) peuvent être conçues très étroites pour réduire la zone de contact sur la couche émettrice (14) réduisant ainsi le courant de recombinaison dans la couche émettrice.

IPC: G01H3/00
Filed: 1988-06-23
Granted: 1991-03-20
Abstract: For the automatic recognition of signal sequences, such as for example speech signals and/or music signals, in each case envelope curves (rectifier 3) are formed from predetermined signals and from signals to be examined and these envelope curves are then band-limited to a narrow, low frequency range (e.g. 2 to 50 Hz). Timing excerpts (approx. 1.7 sec.) are if appropriate stored in a memory (6) as "masks" after digitalisation. When monitoring transmissions, the band-limited envelope curve signals of the signals to be examined are then buffered in a second memory (7) in sections of equal length (of approx. 1.7 sec. in length). Within the period between the arrival of two successive signals to be examined the contents of the buffer (7) are then compared (comparator 8) with all the masks of the first memory (6), a detection signal being generated in the case of a predetermined degree (e.g. 95%) of correspondence.

Title: Programmable circuits
IPC: H03K19/177
Filed: 1988-05-05
Granted: 1991-07-24
Abstract: By using a programmable circuit arrangement it is possible to effect the logical connection of binary input signals. The arrangement comprises a matrix (MA) of transmission lines (DL) and coupling lines (KL) at whose coupling points are arranged coupling elements (KE) according to a function table to be produced. The coupling elements (KE) can assume three different states, the first corresponding to a binary 1, the second to a binary 0 and the third to a binary 1 or a binary 0. Each data transmission line (DL) can be operated as an input or an output by means of a control signal (ST) applied to an input circuit and to an output circuit (AG). The input signals coupled to a coupling line (KL) by data transmission lines operated in the input mode are subjected, on the coupling line, to an AND-connection. On the other hand, the signals coupled by the coupling lines (DL) to a data transmission line (DL) operated in the output mode are subjected, on the data coupling line, to an OR-connection. Depending on the state of the coupling elements (KE), set in accordance with a function table, it is possible to achieve different connections by using the data transmission lines (DL) as inputs and as outputs.

Title: Printed circuit board with a cooling device
IPC: H05K7/20
Filed: 1989-02-18
Granted: 1992-12-23
Abstract: In order to dissipate the greatly increasing power loss resulting from the increasing integration density of semiconductor components, such that the components are not damaged, nowadays it is often no longer adequate to conduct the heat away via the printed-circuit board or to dissipate the heat by convection; additional cooling of the printed-circuit board must then be provided. It is known, for example, for the printed-circuit board to be mounted on a hollow copper plate which has cooling channels passing through it. It is very costly to produce such a copper plate. The idea of the invention is to use the printed-circuit board itself as a cooling device. The printed-circuit board consists of two outer layers (2) and at least one inner layer (4) which are bonded to one another or are connected to one another using a prepreg, by means of hot pressing. Slots or cut-outs are milled, stamped or cut out of the inner layer (4), which slots or cut-outs form channels (5), once the outer layers (2) are fitted, through which a cooling fluid flows.

Title: Method of soldering a wireless component and circuit board with a soldered wireless component
IPC: H05K3/34
Filed: 1989-12-13
Granted: 1993-06-23
Abstract: In order to reduce the thermal stress on surface-mounted (SMD) components (6 - 8), such as miniature resistors, capacitors and integrated circuits, during soldering of their edge-side metallic solder terminal elements (6a - 8a) to printed-circuit board metal terminal surfaces (4a) on the component side (2) of a printed-circuit board (1), at least one solder hole (15) is arranged underneath each solder terminal element. Before flow or wave soldering from the solder side (3) of the printed-circuit board (1), the components (6 - 8) are fixed in their desired position by means of spots of adhesive (13). The soldering process is particularly suitable for the mixed furnishing of the printed-circuit board (1) with wired and wireless components, it also being possible to arrange less temperature- sensitive, surface-mounted components in the conventional manner on the solder side (3) of the printed-circuit board (1). <IMAGE>

Abstract: A method of filling and sealing a container (10) having a deformable bottom (12) with a product (34) having a volume less than the initial volume of the container, but equal to the volume of the final container with its bottom (12) deformed upward. The container is filled and a lid (26) is placed onto the container adjacent to a sealing surface (27). In its initial position enough headspace exists to permit the proper lid placement without squeezing product onto the sealing surface (27). The filled container with its unsealed lid (26) is placed on an anvil (30) in a vacuum chamber (38). The vacuum chamber (38) is vacuumized to a desired pressure and the lid (26) is sealed to the sealing surface (27) by sealing head (40). The container is then removed from the vacuum chamber (38). As a result of atmospheric pressure the bottom (12) is inverted upwardly thereby forcing the product (34) to fill the headspace voids.
