Abstract: APPARATUS FOR CONTROLLING A WEB TRANSPORT SYSTEM     ABSTRACT OF THE DISCLOSURE         Apparatus is provided for controlling a web transport system, such as a tape transport, of the type having supply and take-up reels for supplying and taking up the web, respectively, a tension control circuit for controlling the supply and take-up tension of the web, a web drive, such as a capstan, and a sensor for sensing the movement of the web as it is driven.  The control apparatus includes a web drive detector for detecting the operation of the web drive and, particularly, the speed at which the web drive is driven.  A comparator coupled to the sensor and the web drive detector compares the actual speed at which the web moves and the speed at which the web drive is driven to indicate when the speed at which the web moves differs from the speed at which the web drive is driven, such as when the web slips with respect to the web drive.  An adjusting circuit coupled to the comparator adjusts the tension control circuit when the web speed differs from the web drive speed.     -i-

Abstract: ABSTRACT OF THE DISCLOSURE    Brake apparatus for a railway vehicle including a brake cylinder device of the type having a pair of interconnected pistons of unequal size to which the vehicle brake rigging is connected. The larger power piston forms an application cham-ber and a release chamber on its opposite sides in which air is stored for use in controlling the vehicle brakes.  The brake apparatus further includes a control valve device that is operative responsive to a reduction of brake pipe pressure to conduct flow of air from the release chamber to a position-ing chamber formed on the side of the smaller positioning piston corresponding to the side of the power piston having the application chamber, to effect movement of the inter-connected pistons to a brake application position.  A transfer valve is actuated to connect this flow of air from the release chamber to atmosphere when the positioning chamber pressure exceeds, by a certain amount, a predetermined pressure at which the positioning piston is designed to move the power piston to application position.  This certain amount by which the positioning chamber pressure is required to exceed the predetermined pressure, in order to actuate the transfer valve varies with the release chamber pressure effective at the time of a brake application.

Abstract: ABSTRACT                Improvements in axial turbine flowmeters In order to compensate the hydrodynamic pressure on the turbine of a flowmeter, means are provided to create a zone of reduced pressure of constant value upstream of the turbine hub, together with means for creating a zone of pressure, on the downstream face of the hub, varying in a defined manner as a function of the axial position of the turbine.  The pressure difference thus created on either side of the turbine hub produces a reaction force tending continuously to balance the hydrodynamic pressure of the fluid whatever the flow rate.  The invention is particularly applicable to high flow rate water meters.
