Electrical generation apparatus characterized in that the apparatus incorporates a rotating member comprising a rectangular prism, preferably having a base in the form of an equilateral triangle, which is rotated about an axis extending substantially through its center of gravity. In certain embodiments of the invention, the aforesaid axis is parallel to an applied field of force, either electrostatic or magnetic, through which the member passes as it rotates, the axis being at the edge of the f...

A character generation system for use with high-speed printing/display apparatus. A cyclic code generator is provided which includes electrical delay means such as an N-stage shift register for cyclically generating, in synchronism with the application of the character data to the system, an N-bit serial code representative of the characters in the system's repertoire. Means are provided for selecting the pertinent portions of the N-bit serial code corresponding to the received data and directin...

1. A method of impairing the effectiveness of radio echo location operati in which radio frequency impulses are transmitted to an obstacle and the reflections thereof received at the echo location station, which comprises the steps of initiating the transmission of an interfering signal before the receipt of each said radio frequency impulse, maintaining transmission of the interfering signal during receipt of that impulse, and terminating the transmission of the interfering signal after receipt...

The invention provides a character generation system for converting input data signals into driving signals for a full-page-width mosaic printer or display. The number of columns of a storage matrix which are scanned during the generation process is determined by the character set into the matrix; thus the length of line occupied by a character is determined by the size of the character. Facilities for line justification and the generation of bold, italic and varying-size characters are also out...

A method of generating the bearing surface on a "flying" magnetic recording head. The desired bearing surface is of compound curvature, having a significant crown along an axis parallel to the flying direction and a lesser concavity along an axis transverse to the flying direction. The bearing surface is produced by lapping an essential element of the head, henceforth called "slider" against a control surface. In a first embodiment of the method, the control surface comprises a thin sheet of gla...

The invention concerns ion generation and dispensing apparatus having module form with an electrically conductive bus to which groups of ion generating radiants or clusters are connected, the modules being constructed for connection in series; the provision of means to dispense vapor in air flow created by the flow of such ions; means to use such ions to effect particle collection on surfaces; and means to control such ion polarity in relation to external conditions.

A circuit is disclosed for the generation of multi-level digital waveforms. The basic circuit, with some additions, is also capable of generating two or more of such waveforms, which have determinable phase relationships.

Impure water is continuously sprayed into an elongated conduit having an inlet for the water adjacent one end and an open outlet remote from the inlet while maintaining the inner surface of the conduit at a temperature such that the water not only is flashed into steam but also is substantially immediately converted into superheated steam under the confinement imposed by the inner surface of the conduit with concomitant pressure build-up which propels the steam and superheated steam toward the o...

An arrangement for the generation of timing pulses for a receiver system in which the timing pulses are continuously synchronized with the pulses (input pulses) supplied by a transmitter system. The frequency of an oscillator which generates the timing pulses is changed in accordance with the phase difference between the timing pulses and the input pulses and in accordance with the frequency of the input pulses

A method of and apparatus for generating a hot vapor at high pressure, wherein primary water is sprayed into air during compression thereof and the compressed air with the entrained water as superheated steam is delivered into a combustion chamber where fuel is injected and burned continuously, a secondary water supply being sprayed simultaneously into the combustion chamber and at a rate which determines the temperature of the efflux from said chamber.
