Abstract: A three phase voltage system, balanced and sinusoidal, is converted into another one, having the same properties, but with amplitude, frequency and phase changed, by means of sequential sampling of all input phases. The desired output system is synthetized through a matrix of electronic switches, which are operated sequentially by control pulses having a duration proportional to the instant value of a linear combination of sinusoidal waveforms and with a duty cycle modulated accordingly to the required output parameters.

Abstract: A high temperature stable catalyst is made with fine particles of a base metal such as chromium, hafnium and niobium or their oxides dispersed throughout a matrix made of composite particles having at least one platinum group metal on a ceria promoted, high temperature chemically stabilized refractory oxide powder. The refractory oxide powder can be either alumina, alumina powder which has been calcined at a temperature near incipient alpha alumina formation, silica-alumina or zirconia. The base metal or base metal oxide comprises about 15% to 90% by weight of the total weight and the platinum group metal comprises 0.05% to 10% by weight of the total weight. The catalyst composition can be applied as a washcoat to conventional substrates or it can be formed into shaped catalysts. The washcoat is made by mixing together one slip containing the composite particles with a second slip containing the base metal or base metal oxide particles.

Abstract: @ The invention provides an apparatus for controlling a power assist steering system of the type having an electric assist motor connected to a steering member such as a rack and a steering shaft including first and second coaxial shaft sections rotatable with respect to each other and connected by an elastic member. One of the shaft sections is coupled to the hand wheel and the other to the steering member. A cam operated, reversing switch is coupled across the first and second shaft sections. A drive circuit and the electric assist motor are connected to the reversing switch. A control circuit measures the relative rotation between the two shaft sections and controls the drive circuit. Relative rotation of the two steering shaft sections mechanically controls the reversing switch. The electric assist motor is (i) not electrically connected to the drive circuit when the two shaft sections are in a relative null position, (ii) electrically connected to the drive circuit in one direction when the shaft sections are relatively rotated in a first direction a predetermined amount from the null position, and (iii) electrically connected to the drive circuit in the opposite direction when the shaft sections are relatively rotated in a second direction the predetermined amount from the null position. The control circuit insures that the drive circuit outputs no electrical drive signal until the shaft sections are relatively rotated the predetermined amount. The drive potential increases thereafter as the relative rotation between the shaft sections increases above the predetermined amount.

Abstract: A system of analysing human speech for the determination of the pitch of speech segments while using more than one pitch detection algorithm. In a first elementary pitch meter the amplitude specturum (12) of a speech segment is determined and significant peak positions are determined therein (13). In a second elementary pitch meter the autocorrelation function (15) of the speech segment is determined and significant peak positions are determined therein (16). The significant peak positions of the amplitude spectrum and the significant peak positions of the autocorrelation function constitute the respective input data of the set of operations (14 and 17, respectively) comprising inter alia the following steps:
     - the selection of a value for the pitch or period, respectively, and the detemination of a sequence of consecutive integral multiples of this value and the determination of intervals around this value and the multiples thereof, these intervals defining apertures of a mask;   - the computation of a quality figure indicating the degree to which the significant peak positions and the openings of the mask match;   - the repetition of the preceding steps for consecutive higher values of the pitch or period, respectively, up to a predetermined highest value;   - the selection of a predetermined number of values of the pitch and period, respectively, having the highest quality figures;   - the conversion of the values for the period into values for the pitch;   - combining the values thus found for the pitch with the associated quality figures to form an estimate of the most likely pitch.

Abstract: For a voltage follower unity gain amplifier, used, for instance, as a buffer in a transceiver associated with a data bus, the input signal is fed forward to a comparator (T2-T3) to which the output is also applied. The input is also applied via an amplifier stage (T5-T6) to a transistor (T4) in the com- moned circuit of the comparator, which is a long-tailed pair. Thus, with a connection from the output of the circuit which includes another transistor (T9), provides negative feedback round the comparator, gives a highly stable current.

Abstract: A method is described for natural commutation, carried out by the network or load, of a direct converter (DU) between an M-phase network at the frequency F and an m-phase load at the frequency f, especially of an electrical machine. The direct converter (DU) comprises 2 x M x m thyristors, which directionally connect each network phase to each load phase. The method according to the invention is that, in essence, there are always only two thyristors TX,y and Tx,Y which simultaneously carry current from a network phase X to a load phase y and from a load phase x to a network phase Y. In this arrangement, the thyristors are triggered as a function of the phase of the network voltage and of the load voltage. The method allows a continuous change of the load frequency and of the load voltage from zero up to the network frequency or network voltage. <IMAGE>

Abstract: A method and apparatus for adhering an adhesive-backed tape or sheet to the back surface of a semiconductor wafer having electrical patterns already formed on the front surface thereof. The apparatus comprises a housing forming a vacuum working chamber containing a circular supporfing table for the semiconductor wafer and a roller mechanism for exerting pressure on an adhesive-backed tape or sheet having the adhesive surface thereof located above and facing the semiconductor wafer. In the adhering method, the adhesive-backed tape or sheet is first adhered only at the peripheral edges of the semiconductor wafer, and then the central portion of the adhesive-backed tape or sheet is drown against the semiconductor wafer by a change in pressure in the vacuum working chamber. In this method, since an external force is not applied to the front surface of the semiconductor wafer, the electrical patterns thereon will not be damaged during the adhesion of he adhesive-backed tape or sheet to the back surface of the semiconductor wafer.

Abstract: The permeability of higher permeability zones of a subterranean reservoir of heterogeneous permeability is reduced by injecting (1) an aqueous solution of a crosslinkable water-soluble polymer, a material capable under certain conditions of at least partially crosslinking the polymer to form a gelatinous precipitate, a water-soluble alkaline material in an amount sufficient to maintain the pH of the aqueous solution above the pH at which crosslink­ing occurs until the composition has passed a desired distance through the reservoir, and a water-soluble surface active agent; and (2) a gas mixture comprising an acid gas. A gelatinous foam forms in situ useful for blocking escape of fluids, both gaseous and liquid, into the higher permeability zones of the reservoir during enhanced recovery, typically by carbon dioxide flooding. The polymer-surfactant solution and the gas mixture can be injected in alternating slugs to enhance formation of the gelatinous foam and to allow for plugging of higher permeability zones progressively encountered during recovery operations.
