Patent EP-0251573-A2 (EP)
Inventor: MIDDIEN ISMAIL F
IPC: C11D1/40
Filed: 1987-06-17
Abstract: A cleaning composition, e.g. in the form of an aqueous solution or a powder, comprises a flocculant and a betaine stabilizer. When used in a detergent solution, the flocculant causes contaminates introduced into the water to precipitate and quickly settle to the bottom of the cleaning bucket. This keeps the upper part of the detergent solution clean and prevents a mop from picking up and subsequently re-depositing the contaminates each time it is dipped in the bucket.

Abstract: In order to prevent, especially in the case of concealed air inlet vents designed to feed fresh air into the vehicle interior, snow becoming lodged under the engine bonnet in front of these air inlet vents, the snow being pushed there from the windscreen by the windscreen wipers, it is proposed according to the invention to fit heat exchangers there which are advantageously incorporated into the grilles covering the air inlet vents. This ensures firstly that the fresh air inlet vents are always snow and ice-free and secondly that the windscreen wipers are also heated in their rest position so that neither the windscreen wiper motor nor the windscreen wiper blades can be damaged by frost.

IPC: G11C7/00
Filed: 1988-11-15
Abstract: The transmission of data is often carried out, in particular for reasons of interference immunity, via a double bus by means of differential signals, which are evaluated by a differential amplifier. However, such a differential amplifier has only a limited input voltage range or a dead voltage range for the input signals, in which it does not operate. In order to prevent the voltages going into this dead voltage range on both buses, whether due to a common-mode interference signal on the buses or due to a voltage dip in the feed voltage of the differential amplifier, according to the invention both buses are connected to a setting circuit, which alters the voltages of the two buses by the same extent in the direction out of the dead voltage range. This prevents undefined states of the differential amplifier, without substantially affecting the differential signal on the two buses. Use in the case of an integrated memory is described.

IPC: G06F3/048
Filed: 1988-06-16
Abstract: A digitizer system includes M digitizers, each producing a separate waveform data sequence repre­senting a succession of instantaneous magnitudes of an input signal at sample times determined by a periodic clock signal. Transmission of the clock signal to each digitizer is delayed by a corres­ponding adjustable delay time so as to control the relative sample timing of the digitizers. To adjust sample timing, a sine wave signal is applied as the input signal to each digitizer such that the M digitizers produce M separate waveform data sequences in response to said input signal and the M data sequences are interleaved and windowed to form a single waveform data sequence. A first sequence of complex numbers representing a discrete Fourier transform of the single waveform data sequence is generated and then a second sequence of M complex numbers is formed from elements corres­ponding to relative magnitude peaks of the first sequence. A third sequence of M complex numbers is generated representing an inverse discrete Fourier transform of the second sequence and the phase angle of each number of the third sequence is computed and divided by the input signal frequency to produce a set of M numbers, each representing a timing error for a corresponding one of the M digitizers. The time delay corresponding to each digitizer is then adjusted by the amount of the timing error.
