Abstract: ABSTRACT OF THE DISCLOSURE         The present invention relates to a pressure-resistant locking mechanism for doors of switch boxes. These locking mech-anisms usually operate independently of any function in associa-tion with the switch box.  It can thus happen that the operator forgets to actuate the locking mechanism. Therefore, it is proposed to insert torsion bars, which are connected via levers to springs installed on the door, in hollow spaces formed by U-shaped flanges of the box wall and U-shaped flanges of the door.  The springs always keep the torsion bars at rest so that the locking mechanism is always effective.  When the locking mechanism is to be released the levers must be swung downwards by 90° so that the torsion bars reach the release position.

Abstract: ABSTRACT     An improved current collection structure for a photovoltaic device.  The current collection structure is especially useful for large area photovoltaic devices.  Such devices include a substrate       a semiconductor body      on the substrate       a transparent electrically conductive layer      on the semiconductor body      and a bus grid structure      in electrical contact with the conducting layer      for collecting and carrying current generated by the photovoltaic device.          The structure includes a plurality of grid fingers      electrically resistively interconnected to a busbar      to reduce the effect of current flowing through low resistance defects in the device.        The structure may also include an insulator     interposed between busbar      and the conductive layer     .  The resistive interconnections may be fusible links      .  The conductive layer may have a relatively high sheet resistance and the current collecting fingers      may have varying cross sectional areas to provide substantially equal resistances for fingers of different lengths.  All of these features thwart the effects of low resistance defects in the photovoltaic device.

Abstract: ABSTRACT OF THE DISCLOSURE          Apparatus for the control of relative strand movement, without significantly affecting or altering strand tension, on a braiding machine with two sets of carriers for a strand supply bobbin being rotated in opposite directions and being generally axially aligned, as a set of front and rear strand carriers and supply bobbins.  A set of rear strands pass through peripheral and radially arcuate slots in a carrier mounting table and are guided prior to movement into the slot by a set of cam actuated swing arms movable in a common plane perpendicular to the machine axis.  The rear strands move through an arc segment relative to the machine axis for interweaving with a set of front strands.  The interwoven rear and front strands are led to a circular ring at the front of the machine having an effective diameter coincident with the rota-tional axis of the front bobbins.  The interwoven strands are then pulled from the machine to a "work center" for tight braiding around a core or mandrel.

Abstract: Abstract A catheter tip pressure transducer is employed for purposes of measuring fluid pressure within a living body.        This includes a tubular housing having a pressure inlet aperture therein.  A semiconductor block is carried within the housing and has first and second oppositely facing surfaces, one of which faces the inlet aperture and the other faces in the opposite direction.  One of the surfaces has a recess formed therein of such a depth to define an elongated rectangular shaped membrane.  A pair of elongated grooves are formed in the nonrecessed surface of the semiconductor block. These grooves are in registry with and straddle the longitudinal side edges of the membrane and define therebetween a raised longitudinally extending central portion in the form of a membrane beam which acts as a free beam supported at its opposite ends by the semiconductor block.  Pressure forces acting on the membrane beam result mainly in longitudinally extending deformation of the beam and this is sensed by one or more strain gauges carried by the beam.  By this construction, the cross sectional dimensions are optimized so that the transducer may be mounted in catheters and needles of smaller internal diameters.
