Abstract: The invention relates to method and apparatus for the determination of alcohol concentration of expired air. By visualising current or accumulated measuring value and error in real time during ongoing measurement, interactive control of alcohol determination is enabled with respect to accuracy and time lapse. Preferably the measurement is performed without contact with compensation for the dilution of the breath sample, which is performed by simultaneous measurement of temperature, concentration of water vapour or carbon dioxide. The method is divided into a stepwise procedure based on the dependence of the measuring error on the dilution of the expired air, and accumulated time, both being possible to influence by the test person or operator. Special advantages are being obtained at measurements relative to a concentration limit. The alcohol determination is preferably performed by means of absorption spectroscopy within the infrared wavelength range. The apparatus according to the invention includes sensors for the abovementioned entities, an electronic unit for signal and data processing, a presentation unit, and is embedded in a compact housing for handheld use or integration. The response time of the sensors should not exceed 0.5 seconds in order to fulfil the requirement of real time operation. The housing is controllably openable at measurement, and includes a measuring cell illuminated with collimated infrared radiation and means for active air flow.

Abstract: This system is intended to make it possible, with increased cutting-shears capacity, to feed the concrete-reinforcement bars, which are to be cut, from storage beds (1), starting from a position which is appropriate for cutting, to cutting shears (10). Due to their considerable length of up to approximately 20 m, the concrete-reinforcement bars are often located in the storage beds in an oblique manner in the vertical and horizontal directions and are thus not appropriate for cutting. The concrete-reinforcement bars to be cut are moved, by means of a removal device, that is to say, for example, in bundles by means of a winch, onto a longitudinal conveyor and store which is located parallel to the storage beds (1) and extends in the longitudinal direction of the concrete-reinforcement bars. The longitudinal conveyor and store may be a rolling path (5). It can be oriented in an aligned manner on a cutting-shears path (2) within which the cutting shears (10) are arranged. By means of, for example, driveable rollers (6), then in each case as many concrete-reinforcement bars can be conveyed onto the cutting-shears path (2) as are to be cut by means of one cut of the cutting shears (10). Thereafter, the cutting is carried out by the cutting shears (10). The cut concrete-reinforcement bars are subsequently conveyed from the cutting-shears path (2), for example by means of transverse conveying means (15), onto a collecting path (3) and, from there, are conveyed away. It is essential that, in this manner, concrete-reinforcement bars are fed to the cutting shears always in a position and number appropriate for cutting. <IMAGE>

Abstract: This measures the quantity of heat dissipated by a fluid to a heat exchanger. It has a flow meter, one heat sensor each in the feed and return sides of the water circulation in the heat exchanger, a saw-tooth voltage generator (40), comparators (32, 33), and a counting clock generator (50). The heat sensors, which are constructed as linear measuring shunts (5, 9), are fed respectively from a constant-current source (17, 23), it being possible to switch the inputs (30, 31) of the comparators (32, 33) jointly to calibration resistors (22, 28). A logic element is driven in accordance with the difference between the voltages transmitted by the heat sensors and the saw-tooth voltage. In one circuit state of the logic element, the voltage pulses of the counting clock generator (50) are fed for display to a counting mechanism (47), the constancy of the currents through the heat sensors being guaranteed for the duration of a measurement period by being automatically calibrated at adjustable intervals by means of a control loop (50, 52, 55, 58). This device renders it possible to determine precisely a quantity of heat dissipated, e.g. in district heating, or a quantity of heat absorbed by a consumer. <IMAGE>

Abstract: By means of winder gearing maintaining essentially constant the winding speed a drive motor drives a winding mandril. Operatively associated with the winding mandril is a winding band which is paid-off of a freely rotatable supply roll. Engaging at this supply roll is a jaw brake. The winding or wind-up band is guided over a balance or rocker arm which is upwardly and downwardly pivotable about a pivot axis. By means of a contact or pressing mechanism the balance arm is pressed against the winding mandril. The imbricated printed product stream, infed from a band conveyor, arrives at the balance arm or rocker and the winder band and is supported thereat. The thus supported imbricated printed products are infed from below to a winder gap and in conjunction with the winder band wound-up on the winder mandril. The winder band separates the individual wound layers or plies from one another. By braking the supply the winding of the winder band is accomplished with tension, so that there is formed a snug or tightly wound package in which the printed products are unable to alter their position within the imbricated product formation or stream. Due to the bottom or underfeed of the winder band and the printed products reposing thereon there is required only a single winder or winding band. To ensure for an adhesion between the surface of the winder band confronting the imbricated product formation and the printed products the winder band preferably is formed of an adhesive material. As a further possibility this winder band surface can be rendered adhesive in a suitable manner or provided with an adhesive coating.

Abstract: A filter bag tensioning device for use in a bag house is disclosed. The tensioning device comprises a straight lever arm adapted to be pivotally mounted in the upper reaches of a bag house and carrying, on the end of the lever arm opposite that of filter bag attachment, a semi-fixed counterweight. The semi-fixed counterweight is prevented from rotating as its end of the lever arm moves in an ascending direction from a horizontal position but is free to rotate as its end of the lever arm moves in a descending direction from horizontal, to thereby continuously maintain a desired design tension on an attached filter bag. In a preferred embodiment, the lever arm can also be rotated to a vertical position and then moved longitudinally of its pivot to substantially lower the filter bag attachment point, thereby greatly facilitating attachment and replacement of filter bags and, in a further preferred aspect, to permit these operations to be performed by a workman having both hands free. Also, the tensioning device is preferably mounted so as to permit maximum pivoting of the lever arm during bag cleaning operations and, accordingly, maximum deflection of and minimum stress on a filter bag attached to the tensioning device.

The bus is divided into three sections, all transmitters (S) being successively connected to the first section (B1) and all receivers (R) being connected to the final section (B3) in the same order as the transmitters. The time delay between transmitters and bus is the same for all transmitters and constitutes a fixed value, whereby the total delay on the first section of the bus is determined by the number of transmitters connected. The same condition applies to the receivers so that the delay on the final section (B3) of the bus also is fixed value. The intermediate section (B2) of the bus extends from the last connected transmitter to the first connected receiver, and is variable in length such that in relation to the size of said fixed time delays it gives a selectable predetermined total time delay between transmitter and receiver in the same module. Each of the modules (A-N) contains a local clock oscillator (CL) common to the respective transmitter and receiver. Apart from internal clock signals, the oscillator also sends frame synchronizing pulses (FS) for synchronizing remaining modules (slave modules) each time the module is selected as the master. The synchronization pulses are sent once per frame and parallel to the data information from respective transmitter (S). With the aid of the apparatus in accordance with the invention there is obtained a synchronization process enabling transmission of a first information between an arbitrarily selected pair of modules and a second information between another arbitrarily selected pair of modules using two adjacent time slots without time difference between the sending sequences in the repective time slot.
