Abstract: ABSTRACT OF THE DISCLOSURE A magnetic tape cassette of very small type having a front lid pivotably secured at its supporting arm portions to a cassette housing so as to selectively open or close a front opening portion of the magnetic tape cassette by the elastic deformation of the front lid. The cassette housing has on its side walls edge surface portions which protrude in the direction perpendicular to the rotating direction of the front lid and which come in contact with the inner surfaces of the supporting arm portions when the front lid is opened.  Thus, when the front lid is in its opened state, the front lid can be prevented from being  moved  in  the  lateral  direction  of  the  front  lid  and prevented from being detached away from the cassette housing.          Also, the magnetic tape cassette can be smoothly ejected from a recording and/or reproducing apparatus.

Abstract: ABSTRACT            The exhaust air from the tenterframe (1) conveyed by a fan (7) is fed as combustion air to the burner (13) of a steam boiler (21). The burner (13) is operated with a variable and high excess of air of .lambda. = 1,5 to .lambda.= 3,5. The boiler output is regulated by the fuel supply. The excess of air is increased at low boiler load. The boiler exhaust gas is cooled down below the dew point via three heat exchangers (29,30,31). Thus complete combustion of the organic noxious substances in the tenterframe exhaust air and at the same time recovery, which can be readily utilized, of the tenter-frame waste heat and a lowering of the fuel requirement of the steam boiler are achieved. The same method is also suit-able for purifying the exhaust air from singers.

Abstract: ABSTRACT OF THE INVENTION             A conveyor having a series of pans mounted on chain links with the leading and trailing edges of the pans overlapping.  The trailing edge of each pan has a stiffened transverse arcuate bead contacted by the front corner of a transverse arcuate front bead on the rearwardly adjacent pan under all operating conditions.  The shape of the beads causes the front bead to deflect and self bias into contact.  End plates are welded to the pan except at the front bead from the leading corner to the peak of the arc of the bead.  This leaves the front portion free to flex to develop the bias.  The end plates are also shaped to develop bias to maintain line contact of the front edge of the end plate on the rear portion of the end plate next ahead.  The plates overlap in all operating conditions.

The prescribed pulse train for a subject is delivered by a delivery device, which also provides monitoring of the averaged voltage amplitude of the positive portion in terms of either voltage or current value.  The impedance of the subject is expected to change over time and cause the individual pulses to vary from predetermined limits.  When this occurs, then a subsequent generation of pulses will be changed so that  the  pulses  are  again delivered within  the predetermined value limits or boundary.  Tracking and generation can be operationally crossed, if desired, so that a voltage out of boundary will cause the current of a subsequent pulse to be changed or vice versa.

Abstract: ABSTRACT OF THE DISCLOSURE            A powered respirator comprises a motor-driven fan unit drawing air through an upstream filter for delivery to a facepiece.   Operation of the fan motor is controlled in response to a differential pressure sensor tapped in across the fan unit so as to reduce the fan throughput in response to an increase in the pressure differential and to increase the fan throughput in response to a decrease in the pressure differential, and thereby match the delivery of air to the breathing demand of the wearer. The diaphragm or other pressure-responsive member of the sensor is isolated from unfiltered air and can therefore provide no leakage path for contaminants to the facepice. In an alternative embodiment the positions of the fan and filter are reversed so that the fan is upstream of the filter, and similarly controlled in response to the differential pressure across the fan.   In the latter arrangement any contaminant which could pass through the pressure sensor is removed by the downstream filter before delivery to the facepiece.
