Abstract: For a method for determining the inherent moisture content of the respective aggregate fractions in the batch production of building material compositions, in particular concrete compositions, the dry weight belonging to a fraction serving as reference value for the actual aggregate fraction, it is proposed to determine, for each of the aggregate fractions in its completely dry state, by means of volumetric dosing a reference value for mass throughput and then to supply the aggregate fractions necessary for a given building material composition separately after one another to a balance and to weigh them, from which, by means of the dosing time of the respective actual aggregate fraction and its reference value for mass throughput of the dry fraction, a weight value is then determined, with which the weighing result is compared. The inherent moisture content of the dosed aggregate fraction can be determined via the difference between the weighing result on the one hand and the weight value for the dry aggregate fraction on the other hand. A moisture content measuring method is thus available, in which the inherent moisture content of the aggregates is determined over their totality and not over part quantities.

Abstract: In a nitrogen generation process in which a stream of air is compressed in compressor 11, is cooled and has water vapour and carbon dioxide removed therefrom in a reversing heat exchanger 16, and is separated in a rectification column 24, a gaseous nitrogen product stream 30 is produced. An air turbine 22 is operated to produce refrigeration for the process. The process is also used to purify merchant liquid nitrogen typically containing from 0.5 to 5 vpm of oxygen. A stream 51 of such merchant liquid nitrogen is introduced into a stage of the rectification column where the liquid nitrogen has a substantially matching composition. A stream 36 of purified liquid nitrogen is withdrawn from the top of the column 24. The purified liquid nitrogen can be produced at a rate in excess of that made possible by the turbine 22 without reducing the efficiency of gaseous nitrogen generation.

Abstract: An integrated sample-and-hold circuit (10) includes a capacitor (14) that is charged through a channel, such as a first input transistor's (20) channel. Feedback circuitry (36) connected to the first transistor's channel leads maintains approximately zero voltage difference between the channel leads to prevent leakage current when the first transistor is turned off. Isolation circuitry, such as a second input transistor (28), isolates the first transistor from the input voltage while a voltage level is being stored, and the gates of both input transistors can be connected to receive the same store signal. The feedback circuitry can include a follower transistor with its gate connected to the first transistor's output lead and a first channel lead connected to the first transistor's input lead and to load circuitry that maintains current flow through the follower transistor. To ensure that it does not pass current to or from the capacitive element, the follower transistor can be an MOS device or other insulated gate transistor. The follower transistor's other channel lead can be connected to a bias voltage that, together with the current flow, keeps the follower transistor's gate and first channel lead at the stored voltage level. The load circuitry can include a transistor identical to the follower transistor, with one of its channel leads connected to the follower transistor's first channel lead and with its other channel lead and its gate lead connected to a bias voltage that maintains sufficient current flow through the follower transistor. The substrate can be of an insulation material such as glass, quartz, sapphire, silicon dioxide, or silicon nitride, and the circuitry can be thin film structures, amorphous silicon, polysilicon, or single crystal devices, so that the only significant leakage path to and from the capacitive element is through the first input transistor's channel.

Abstract: Increasing travel speeds bring about high pressure surges when trains pass or at tunnel entrances. In order to prevent possible ear discomfort for the passengers, pressurised railway carriages are used whose air tightness however decreases over its service life. As a result, the air pressure surges occur to an increasingly large extent also inside the carriage. In order to identify these effects according to number and strength, and in order to derive economically viable resealing frequencies therefrom, the device according to the invention is used to detect and register brief air pressure fluctuations in a physiologically weighted manner. The localisation of leakage points is also possible. This device operates purely electronically using exclusively commercially available components; it therefore has a high degree of operational reliability, is cost-effective and small in terms of volume.

Title: Tape printing device
Inventor: HIROKI GODO
IPC: B41J32/00
Filed: 1991-05-15
Abstract: A label tape printer has a more-or-less conventional label tape cassette gear train mechanism (23 - 28) except that the main motor (3) has a clutching means (22,23, 51, 53) that can disengage the motor when the motor is not on and turning. This allows the motor loads to turn the gear trains without any tendency of the motor to hold the gear train frozen by its advantage through the gear reduction. Therefore a pull on the label tape end will result in the entire gear train turning and thereby preventing the ink ribbon from forming a loose loop that can get sucked into an adhesive tape sandwich (with catastrophic results). The label tape cassette is provided with a guide roller having deep grooves, giving the appearance of a piece of machine screw threaded stock, tat is positioned to keep the adhesive tape from sticking to the inside walls if the tape reels loosen. The adhesive tape has a reduced surface area on the guide roller to become stuck on it also.

Filed: 1991-05-27
Abstract: A comb filter serves to process an input digital video signal which is derived from an analog video signal by a analog-to-digital conversion including a sampling process responsive to a system clock signal. The comb filter includes a separating device for separating the input video signal into a plurality of video signals which are offset with each other in timing and which have a clock rate equal to 1/N times a clock rate of the system clock signal where N denotes a predetermined natural number greater than 1. A first delaying device serves to delay a first output signal of the separating device. A chroma signal processor separates a first chroma signal in response to the first output signal of the separating device and an output signal of the first delaying device. A first subtracter serves to subtract the first chroma signal from the output signal of the first delaying device. A second delaying device serves to delay a second output signal of the separating device. An interpolating device serves to interpolate the first chroma signal into a second chroma signal to compensate for a difference in timing between the output signal of the second delaying device and the first chroma signal. A second subtracter serves to subtract the second chroma signal from the output signal of the second delaying device. A combining device serves to combine an output signal of the first subtracter and an output signal of the second subtracter into a luminance signal.

Abstract: A frequency converting circuit serves to generate a clock signal of a video sampling frequency from one of a clock signal or a sync signal outputted from a digital audio interface. An oscillator (9) serves to generate a clock signal of the video sampling frequency. A video reference generating circuit (10) serves to generate a video timing signal, an audio timing signal, and black burst data from one of the clock signals generated by the frequency converting circuit (12) and the oscillator, and from an output reference video signal. In cases where the recording audio data is recorded or edited, a first switching device (13) replaces the recording video data by the black burst data, and feeds the black burst data to the video recording processing circuit. In these cases, a second switching device (14) replaces the video-sampling-frequency clock signal from the oscillator by the video-sampling-frequency clock signal from the frequency converting circuit, and feeds the video-sampling-frequency clock signal from the frequency converting circuit to the video reference generating circuit. In addition, a third switching (15) device suspends detection of an output reference fed to the video reference generating circuit, and inhibits a timing reset of the video reference generating circuit.

Abstract: An interrupt controller is so that configured that if the priority level is divided into 2 n  or less levels, the priority levels are scanned in the order of 2 n  → 2 n-1  → · · · 2⁰, and the priority levels having the same order of priority are scanned on the basis of the default values at only one timing. Therefore, even if interrupt requests having the same priority levels compete with each other, an interrupt request signal having the highest priority level can be detected from the competing interrupt requests with only (n+1) timings.
