Abstract: The invention relates to a method for preparing low calorie pasta product comprising glutinous flour, an added fiber source, a reducing agent, and water. The use of a reducing agent in the method of the invention neutralizes oxidizers present in or on the surface of the added fiber source whereby improved texture and mouth feel of high fiber-­containing pasta is achieved. The amount of corn fiber, soy fiber, oat fiber, etc. in the pasta can be up to about 30 per cent by weight without adverse effect on pasta texture or color. By replacing some of the glutinous flour in the pasta with bulk fiber, the calorie content of the pasta is reduced.

Abstract: Television receiving apparatus receives television signals broadcast over preselected broadcast channels by different television broadcast systems. A plurality of demodulators (27, 28) demodulate and concurrently display the television programme broadcast by the different systems. A processor (26) selects a broadcast channel to be demodulated by at least one of the demodulators (27, 28); and a detector (32) detects if television signals are being broadcast over the selected channel. If so, the sound carrier frequency derived from the broadcasted television signal is determined and the television broadcast system is identified as a function of that carrier frequency. A memory (33) stores an indication of the selected broadcast channel and the identity of the television broadcast system which uses that channel; whereafter the processor (26) is advanced to select yet another channel and to identify the system by which television signals are broadcast over that other channel. As this process continues, the memory (33) stores indications of channels which can be received and identities of the systems of those channels. Subsequently, desired broadcast channels together with the identities of the systems can be retrieved from the memory (33) to configure the respective demodulators (27, 28) in a manner compatible with those systems to enable the programmes which are broadcast over the retrieved channels to be demodulated and concurrently displayed, such as in a picture-in-picture format.

Abstract: 5 n7 A self-propelled cleaning vehicle (10) comprises matter removal means (18) including primary brushes (24,26) and an additional or third brush (28). The third brush (28) is mounted on a brush mounting arm (46) comprising inner (48) and outer arm (50) portions, pivotally interconnected (52), and controlled by a control linkage (58) interconnecting them and actuated by a remote actuating ram (72) at the inboard end of the assembly. The outer arm portion (50) is of telescopic construction for length-adjustment. The telescoping portion is provided by two parallel rams (98,100). Oil flow to the hydrostatic motor (104) passes through the rams and their piston rods themselves. The pressure on the piston is used to telescope the rams (98,100). When the third brush (28) is in use, contour-following means enables the inboard primary brush to follow the peripheral contours of a surface it is sweeping without driver intervention. Such automatic contour-following is activated by driver-controlled selection (113) of a contour-following control mode which causes the inboard brush to move outwards until it meets, for example, a gutter profile. Position sensing switches (124A) enable the primary brushes (24,26) to automatically adopt standard sweeping positions when a non-contour following mode is selected.

Abstract: A process is proposed for totally or partially coating with a gold layer from an organo-metallic compound applied to a substrate by irradiation with UV light of a defined wavelength which brings about a photolytic cleavage of the organo-metallic compound. In particular, tetrachloroauric(III) acid trihydrate dissolved in diethyl ether or alcohol is applied to a substrate as a film and, after drying, this solution film is irradiated with UV light of an incoherent Xenon excimer UV source having a wavelength of 172 nm, resulting in the deposition of a gold layer. Fine structures can be obtained by forming images with masks. The gold layer deposited can then be electrolessly metallised, for example copper-plated. <IMAGE>

Abstract: A replica of a microwave input signal is subtracted from an amplified version of the input signal produced by main power amplifiers (52a,52b) to produce an error signal corresponding to distortions introduced into the input signal by the power amplifiers (52a,52b). The error signal is amplified by an error amplifier (30), and subtracted from the amplified input signal to produce an output signal in which the distortions have been canceled. A bandpass filter (54) is provided immediately following the power amplifiers (52a,52b) to suppress or block intermodulation products generated in the power amplifiers (52a,52b) which are outside the bandwidth of the input signal and which could overload the error amplifier (30) to generate further distortion. A second filter (78) may be provided through which the replica signal passes to better match the replica signal to the amplified and filtered input signal. Suppression of the out-of-band intermodulation products enables operation of the power amplifiers (52a,52b) very close to their saturation limit with maximum efficiency. A second error cancellation branch (56,60,62,64,66,68,70,72) may be provided to produce further reduction of distortion, and may include a third bandpass filter (80).

Abstract: A static random-access memory is disclosed which utilizes bit line pairs for each column of memory cells for communication of data between external data terminals and the memory cells. A precharge transistor is connected between each bit line and a precharge voltage, for example V ec , and an equilibration transistor is connected between the bit lines in each bit line pair. The precharge and equilibration transistors are controlled according to selection of the column, so that all columns which are not selected by the column address are precharged and equilibrated, including the unselected columns in the same sub-array as the selected columns. In an additional embodiment of the invention, a data transition detection circuit also controls the precharge and equilibration transistors, so that the precharge and equilibration transistors for the selected columns are turned on responsive to an input data transition during a write operation ; this assists the write drivers in more quickly writing the new data onto the bit lines.
