Abstract: Device for continuously controlling the amplitude of an essentially sinusoidal alternating electric current (16) flowing in a circuit (15), comprising a control element (17) located in the circuit (15) and means (8) for operating the control element, which electrically exhibits similarly advantageous characteristics as those of known regulating transformers, particularly with respect to low reactive power losses, low noise factors and relatively wide adjusting ranges, but, in contrast to these transformers, allows an almost delay-free continuous electronic control. The control element (17) comprises a parallel circuit of a first and of a second current branch (1, 3) with an inductive resistance (2) in the first current branch (1) and a controllable switching element (4, 5), which can be put into a blocking and into a conducting state, in the second current branch (3), and the means for operating the control element (17) comprise control means (8), in order to put the switching element (4, 5) from the blocking state to the conducting state in each half wave of the alternating current via a variable part of the half wave which can be controlled by the control means (8). <IMAGE>

Abstract: A method in the production of hydrogen peroxide is described, utilising the so-called anthraquinone process in which alkylated anthraquinones dissolved in organic solvents to form a liquid working solution, are alternately reduced and oxidised. The working solution is subjected to catalytic hydrogenation by contacting it with hydrogen in the presence of a hydrogenation catalyst. The contact with hydrogen is established in a fixed catalyst bed comprising one or more solid catalyst bodies, each of which consists of a thin-walled, coherent. solid body of a structure forming parallel channels through which the working solution and hydrogen gas are allowed to pass. The channels of the catalyst bed are of equal length and parallel to the direction of flow of the working solution. The catalyst preferably is provided in a thin layer on the walls of the structure, preferably by means of a porous carrier.

Abstract: A single carrier is amplitude-modulated by a signal which is a transform (as the sine function) of the audio signal, and one set of sidebands is removed. In a receiver (76), the signal can be recovered by first deriving the Hilbert transform of the sine transform, and multiplying it by the signum of the derivative of the original audio signal to obtain the cosine transform. The sine and cosine transforms are then decoded to obtain the original audio signal.

Title: Burst signal generator
Inventor: KASAHARA TOSHIHARU
IPC: G06F1/03
Filed: 1984-09-05
Abstract: @ A set value of a frequency setting register (11) is accumulated upon each occurrence of a clock signal, and a waveform memory (14) is read out by using the accumulated value as an address. In the waveform memory, amplitude data of one cycle of the waveform of a burst signal to be generated are stored at fixed phase intervals. The output read out of the waveform memory is converted into an analog signal. A wave-number counter (21) counts the number of times the amplitude data of one cycle is read out of the waveform memory and, when having counted by preset number of waves, yields a wave-number counting end signal. After the occurrence of the wave-number counting end signal a phase counter (31) counts clock signals, and when the count value of the phase counter reaches a value corresponding to a preset end phase, the generation of the burst signal is stopped.

Abstract: (D A novel irradiation process and products made thereby are disclosed. Biological media such as blood, blood fractions, genetically engineered protein products and vaccine preparations are treated by said process, photolyzing nucleic acids in preference to proteins in said media. E.g., DNA- or RNA-containing pathogens are inactivated while leaving the proteins substantially intact or functional. In general, the process comprises irradiating the medium with pulsed light of wavelength and flux selected so that (1) the nucleic acids in their ground state absorb radiation and thereby rise to an excited state or states, (2) the nucleic acids in their excited states absorb radiation and thereby rise to higher energy states and undergo photolysis, and (3) the proteins in their ground or their excited states do not absorb sufficient radiation to undergo substantial photolysis. It is surprising and unexpected that nucleic acids in their excited states undergo efficient photolysis whereas proteins under the same conditions in the same medium are kept substantially intact.

Abstract: A method and apparatus for operating an internal combustion engine that substantially improves the fuel efficiency by utilizing heat normally discharged to the ambient to condition and prepare the fuel mixture prior to entry into the combustion chambers. The apparatus comprises a fuel vaporizer, a fuel mixture heater and a mixture homogenizer located in a fuel mixture flow path intermediate the vaporizer and the heater. The fuel vaporizer includes structure defining an inner heat exchange chamber which receives air and entrained fuel discharged by a fuel introducing device such as a carburetor.

To facilitate the transfer of heat to the fuel mixture, a pair of heat exchange members are disposed in the chamber and include a supply tube defining a flow path for fluid carrying engine waste heat and a plurality of bristle-like heat exchange surfaces radiating outwardly from the supply tube. The bristle-like surfaces are located in heat exchange relation with the fuel mixture in the vaporizing chamber and transfer heat from the heat exchange fluid to the fuel mixture as the fuel mixture passes through the vaporizer.

Abstract: There is disclosed a solid ultrasonic delay line comprising a solid ultrasonic delay medium on which polygonal multiple-reflective surfaces are formed. An input transducer for radiating longitudinal waves is disposed on one of the reflective surfaces.

Ultrasound absorbers cover at least portions of the main boundary surfaces perpendicularto the reflective surfaces. Spurious waves of the longitudinal waves radiated from the input transducer are transformed by the main boundary surfaces into transverse waves which enter the absorbers. In addition to, or instead of, the absorbers, ultrasound diffuse reflection regions are formed on at least portions of the main boundary surfaces perpendicular to the reflective surfaces, in order to cause the spurious waves of the longitudinal waves from the input transducer to be diffusely reflected at the main boundary surfaces.
