Patent ES-441943-A1 (ES)
Title: Delta modulation apparatus
IPC: H04B14/06
Filed: 1975-10-21
Abstract: Disclosed is a digital modem using continuously variable sloped delta modulation and adapted for digitizing voice signals in a telephone system. In the analog to digital direction (A/D), an analog input signal is converted into a digital output, the output logic condition being indicative of the direction of change in amplitude from the last signal input. The signal pulse indicating positive change or absence of pulse indicating negative change is passed to a shift register for transmission of the first pulse signal and storage of a plurality of bits. A feedback network receives the pulse bits from the shift register, and the bits are converted to a summed signal for resolution into a reconstructed or simulated signal against which the incoming signal is checked. For the receiving or D/A direction, a somewhat similar circuit in reverse is used to reconstruct an analog signal from the received data bits.

Patent ES-452652-A1 (ES)
Title: Methods and apparatus for reducing intelligible crosstalk in single sideband radio systems
IPC: H04L25/08
Filed: 1976-10-22
Abstract: Intelligible crosstalk in microwave radio systems employing single-sideband modulation is substantially eliminated by phase-modulating the AM carrier-wave prior to its modulation by the baseband signal. The phase-modulation may comprise a periodic signal, such as a single sinusoidal tone or pseudo-random noise, or it may comprise an aperiodic signal such as a truly random noise. In this latter event, the coding signal is transmitted to the receiving location to ensure proper demodulation of the encoded signal.

Title: Continuous ignition turbo motor
IPC: F02C5/02
Filed: 1980-03-27
Abstract: An internal combustion engine, which is particularly adapted for vertical take-off and landing aircraft, has a plurality of fixed annularly arranged combustion chambers and an opening in each chamber. The chamber openings are arranged to define either a cylindrical surface or a plane surface.

Patent ES-8206849-A1 (ES)
Title: Schottky barrier photovoltaic detector
IPC: H01L31/07
Filed: 1981-02-20
Abstract: A platinum-cadmium sulfide Schottky barrier photovoltaic detector which is capable of sensing near ultraviolet and short wavelength visible radiation with extremely small response to wavelengths longer than about 5200 angstroms. The detector is fabricated with both the ohmic and barrier contacts located on the same side of the cadmium sulfide substrate to facilitate wire attachment by high-speed bonding techniques. A titanium-gold-titanium infrared shield structure is deposited directly on the substrate and is utilized to provide a connection between the ohmic contact and the substrate. An insulating layer of silicon dioxide covers the shield structure. A thin layer of platinum is deposited directly on the substrate in a small central optically active area surrounded by the insulated shield structure. A metal boundary layer overlies the periphery of the platinum layer and prevents the barrier contact metalization from affecting the properties of the Schottky barrier. Both the ohmic and barrier contacts may be formed of a titanium adhesive layer and a layer of gold. The gold portions of these contacts touch the shield structure and the boundary layer through separate windows etched in the silicon dioxide insulating layer.
