Title: Preparation of an ultra-black coating due to surface morphology
IPC: C23C18/36
Filed: 1980-04-18
Granted: 1983-04-13
Abstract: The invention provides a method of producing an ultra-black surface coating, having an extremely high light absorption capacity, on a substrate, such as a metal, ceramic, glass, or plastic, the blackness being associated with a unique surface morphology consisting of a dense array of microscopic pores etched into the surface, as well as the resulting coated substrate. The method involves preparing the substrate for plating with a nickel-phosphorus alloy, as by cleaning and/or activating it, immersing the thus-prepared substrate in an electroless plating bath containing nickel and hypophosphite ions in solution until an electroless nickel-phosphorus alloy coating has been deposited on the substrate, and then removing the substrate, coated with the electroless nickel-phosphorus alloy, from the plating bath and washing and drying it. The dried substrate, coated with the electroless nickel-phosphorus alloy, is then immersed in an etchant bath consisting of an aqueous solution of nitric acid, wherein the nitric acid concentration ranges from a 1:5 ratio with distilled or de-ionized water to concentrated, until the coated surface of the substrate develops ultra-blackness, the blackness being associated with the surface morphology as described above. The resulting substrate, covered with the ultra-black coating is thereafter washed and dried. The ultra-black surface, which has a spectral reflectance on the order of about from 0.5 to 1.0% at wavelengths of light of about from 320 to 2140 nanometers, finds use as a solar collector in the field of solar energy.

Abstract: An electric-hydrostatically powered vehicle has an electric motor (42) connected through a gear box to a hydrostatic pump (34) which powers the vehicle. The vehicle chassis includes a main frame portion (16) and a removable subframe portion (72) which is resiliently mounted in spaced-apart, overlying relationship on the main frame portion. The subframe provides a platform for mounting the motor, gear box and pump independently of the main frame of the vehicle to define a removable drive module. The subframe provides planar mounting surfaces (82) that enable translational and angular positioning of the motor and gear box in three dimensions to align their shafts. The module is preassembled by mounting the motor and gear box on the platform, aligning and connecting their shafts, and securing the motor and gear box to the platform. Thereafter, the module is installed as a unit into the vehicle, the alignment of the shafts being undisturbed. A three-point resilient mount (148, 150, 152) isolates the subframe from shock and vibrations imparted in the main frame.

Title: Method for making bicomponent filaments; transition tube for use in making bicomponent filaments
IPC: D01D5/32
Filed: 1981-02-23
Granted: 1985-09-11
Abstract: The method for making bicomponent filaments from two spin dopes wherein the dopes are assembled into alternating layers in a feed tube leading to a transition tube connected to a conventional spinnerette, the layers then being fed through the transition tube and the spinnerette to form filaments. The feed tube has a constant cross-sectional area along the length thereof and the transition tube has a parabolic configuration such that the linear flow rate of the assembled dope layers passing through the transition tube decreases at a uniform rate as the cross-sectional area of the stream of assembled layers is increased to the cross-sectional area of the spinnerette, to thereby maintain the distinctness of the interfaces of the layers and thus insure that good bicomponent filaments will be formed.

Granted: 1984-07-11
Abstract: Process and device for protecting the transmission of vocal signals along a limited band-width analog transmission channel (for instance a vocal CCITT channel), protecting against illicite listening. By exploiting the speech information perceived by the human ear, the vocal signal to be transmitted is digitalized and undergoes a corresponding information reduction (A(f)) based on Fourier's transformation. The necessary information protection can thereby be obtained in the subsequent coding, with respect to the transmission distortions and the modulation is optimally adapted to the transmission behaviour. The digital form existing before this coding can be easily digitalized so that the transmitted analog signal is totally incomprehensible and can not be reconstituted even through the modem methods of analysis, while for the authorized listeners a good intelligibility subsists. By this process, through the modern means of the digital signal processing technique, an optimal solution to the safe analog transmission of speech can be achieved.

Abstract: Transponders are arranged at control locations associated with sections of a track or travel path. Each transponder is in wireless communication through an inductive transmission path and an optical transmission path with a conveyor present in the operable range of the transponder. Each transponder is in communication with a central system control via an associated group control unit by means of two-wire lines or conductors. The operational mode of each transponder is controllable by means of a multiplexer such that the transponder operates either as a responder or answering device with simultaneous unidirectional signal transfer and which responder is to be interrogated by a conveyor or as a bidirectional signal transmitter. The apparatus selectively functions as a location or site code transmitter and presence indicator for the individual conveyors or as bidirectional data transmitter with isolated directions between the conveyors and the central system control. Due to such dual utilization only one type of layout element is required, resulting in a high reduction in the installation expense and its maintenance. The apparatus is intended for the modular erection of conveyor installations of different sizes and output and is equally well suited for partially autonomous as well as for central control of the conveyors.

Abstract: This invention provides a uniquely designed switched capacitor multiplier/adder (129) which also functions as a digital-to-analog converter in a single subcircuit. The multiplier/adder, in a single operation, multiplies an analog voltage by a binary coefficient, and sums this product with a second analog voltage. The use of this unique subcircuit significantly reduces the space requirements for the construction of, for example, a speech synthesis circuit utilizing linear predictive coding over prior art circuits. This size reduction in turn significantly reduces the manufacturing costs for this circuit over prior art circuits, and additionally allows the option of including on the speech synthesis chip a memory for the storage of binary representations of to-be-synthesized speech patterns. 
<??>In one embodiment of this invention, a novel structure and method are provided which minimize error components in the synthesized speech signal due to voltage errors inherent in the use of analog sample and hold circuits which are used to store the forward and backward prediction errors utilized in the linear predictive coding technique.
