    Instrument measures metabolic breathing rate and dynamics of human beings in atmospheres ranging from normal air to 100 percent oxygen at ambient pressures from 14.7 to 3.0 psia. Measurements are made at rest or performing tasks up to maximum physical capacity under either zero or normal gravity

    An apparatus is described for the measurement of metabolic rate and breathing dynamics in which inhaled and exhaled breath are sensed by sealed, piston-displacement type spirometers. These spirometers electrically measure the volume of inhaled and exhaled breath. A mass spectrometer analyzes simultaneously for oxygen, carbon dioxide, nitrogen, and water vapor. Circuits responsive to the outputs of the spirometers, mass spectrometer, temperature, pressure, and timing signals compute oxygen consumption, carbon dioxide production, minute volume, and respiratory exchange ratio. A selective indicator provides for readout of these data at predetermined cyclic intervals

    History, landscape, nation: British independent film and video in the 1970s and 1980s

    This article examines uses of history in British independent film and video in the 1970s and 1980s, looking at ways in which radical pasts were called on to foster struggle in the present. In tracing the specific influence of New Left cultural historians on independent film and video, as well as television, during these two decades, this paper also suggests ways in which the nation is figured, contested and re-drawn in specific works by Kevin Brownlow and Andrew Mollo, Phil Mulloy and Black Audio Film Collective. A rich and diverse framework of Left historical discourse is outlined, suggesting that the exploration of a socialised landscape (the city as well as the country) played on and renegotiated existing myths and tropes of Britishness, identity and belonging. This article also fills a gap in existing accounts of radical film’s uses of history, going beyond valedictory accounts of modernist historiography to assert the vitality of a complex counterpublic discourse. It concludes with a reflection on problems in the depiction and imagination of the past today

    Operation of the HP2250 with the HP9000 series 200 using PASCAL 3.0

    Get PDF
    A computer program has been written to provide an interface between the HP Series 200 desktop computers, operating under HP Standard Pascal 3.0, and the HP2250 Data Acquisition and Control System. Pascal 3.0 for the HP9000 desktop computer gives a number of procedures for handling bus communication at various levels. It is necessary, however, to reach the lowest possible level in Pascal to handle the bus protocols required by the HP2250. This makes programming extremely complex since these protocols are not documented. The program described solves those problems and allows the user to immediately program, simply and efficiently, any measurement and control language (MCL/50) application with a few procedure calls. The complete set of procedures is available on a 5 1/4 inch diskette from Cosmic. Included in this group of procedures is an Exerciser which allows the user to exercise his HP2250 interactively. The exerciser operates in a fashion similar to the Series 200 operating system programs, but is adapted to the requirements of the HP2250. The programs on the diskette and the user's manual assume the user is acquainted with both the MCL/50 programming language and HP Standard Pascal 3.0 for the HP series 200 desktop computers
