Title: Frequency agile band select filter
Inventor: NICHOLLS CHARLES
IPC: H03D7/16
Filed: 2023-06-28
Abstract: A filter, apparatus, system and method are provided for implementing a band select filter, for example a frequency agile band select filter. In an implementation, the filter includes two separate signal generators configured to provide different local oscillator signals to an input mixer and to an output mixer, resulting in the filter output frequency being different from the filter input frequency. This is in contrast to known approaches which use the same signal generator to drive both input and output mixers. The filter may include two bandpass filters, three mixers, and three signal generators, each signal generator uniquely associated with one of the mixers, and configured to provide bandwidth control. A system of filters may include a set of bandpass filters, a plurality of sets of mixers, and a plurality of sets of signal generators, each set of signal generators being associated with a different set of mixers.

Filed: 1978-11-20
Abstract: Epitaxial and diffusion-type planar diodes and solar cells utilize low-cost refined metallurgical silicon substrates having a substantially higher impurity content than conventional high-cost, high purity semiconductor grade silicon. The epitaxial type products have an n-on-p-on-p substrate configuration, while the diffusion-type products have pentavalent impurities diffused therein to form a p-n junction in the low-cost silicon substrate. One embodiment employs a multigrained refined metallurgical silicon (RMS) prepared by precipitating essentially iron-free silicon platelets from a solution of metallurgical grade silicon in molten aluminum, melting said refined platelets in contact with a silica slag and pulling silicon boules from a melt of said refined metallurgical silicon (RMS). By directionally solidifying the refined silicon-slag melt, a multigrained, directionally solidified refined metallurgical silicon (DS/RMS) is obtained, with boules being pulled from a melt thereof for use as said low-cost substrate. The DS/RMS may also be re-melted and directionally solidified a second time with the boules being pulled from said twice directionally-solidified material being a desirable low cost, single crystal material suitable for use as said substrate for planar diode and solar cell applications.

IPC: E02F5/10
Filed: 1979-03-21
Abstract: The invention relates to an apparatus for the entrenching of pipes in underwater beds, of the type in which a framework, provided with excavating means, is positioned across the pipe (11) to be entrenched and dragged along the pipe so as to excavate two parallel trenches adjacent to both sides of the pipe, the pipe being entrenched due to the collapsing (either spontaneous or caused by disgregating means) of the bed zone thus remaining under the pipe already laid onto the bed. The excavated material is removed by means of a pump and discharged again, at a predetermined distance from and rearwardly of the framework, on the entrenched pipe. The framework is provided with side supporting skid members, by which furthermore the entrenching height is adjustable.

Abstract: Dans l'installation, le crypteur (1) échantillonne le signal initial à période constante et produit un signal crypté par lecture des échantillons sous la commande d'un signal de cryptage ayant une période prédéterminée multiple de la période d'échantillonnage. Le décrypteur (2) effectue les opérations inverses des précédentes afin de restituer le signal décrypté analogue au signal initial. Le crypteur et le décrypteur comprennent des circuits à retard analogiques (11, 22). Dans le crypteur (1), le signal analogique initial est échantillonné et écrit à la cadence de la période d'échantillonnage pendant ladite période prédéterminée afin de remplir la totalité d'une ligne à retard analogique, puis les échantillons sont lus selon leur ordre initial à des instants ayant une répartition temporelle prédéterminée par le signal de cryptage et différente de celle répartie des instants d'écriture précédents dans ladite période prédéterminée. Le signal crypté est ainsi obtenu par compressions et expansions temporelles des échantillons du signal initial. Des signaux de cryptage commandant ces compressions et expansions sont obtenus par modulation en impulsions de plusieurs signaux à ladite période prédéterminée, afin de permettre la sélection d'une pluralité de code de cryptage. L'installation peut être utilisée pour la reception sélective d'émissions spécialisées notamment radiophoniques.

Title: Hammer bank assembly

IPC: B41J9/127
Filed: 1981-02-13
Abstract: An improved print hammer (10) incorporating crossed- spring support wires (20, 22) having a round cross section so as to render the hammer relatively flexible in a direction lateral to hammer travel during printing. The spring wires are connected between a lower body portion (18) and a foot section (24). The lower body portion and foot section are designed so that the spring wires enter them substantially perpendicularly, thereby reducing stress. The foot section incorporates a pair of mounting pegs (36, 38) which serve to accurately locate the hammers in a hammer bank assembly. A pair of weights (52) can be included on the spring wires in orderto dampen recoil motion which occurs after the hammer impacts against a print character. The crossing point (21) of the spring is positioned so that the springs are flexed by a constant bending moment, thereby reducing stress on the springs.
