Abstract: ABSTRACT OF THE DISCLOSURE           A grate for use in industrial furnaces has a frame which supports a number of elongated parallel grate bars having a T-shaped or U-shaped cross-sectional outline.  One end portion of each bar has a socket which overlies a portion of an elongated rail forming part of or secured to the frame.  The other end portions or the regions close to the other end portions of the bars are coupled to each other by a transverse shaft which holds the bars against movement at right angles to their longitudinal extensions and away from the frame.  A second coupling system is provided close to the one end portion of each bar to hold the bars against movement in the aforementioned direction.  The second coupling system may include lateral projections provided on the bars and extending below or into openings of the neighboring bars.  Alternatively, the second coupling system may include locking bolts which are affixed to or movable transversely of alternate bars and extend below or into openings of one or both neighboring bars.  A single locking bolt can extend through openings in the lower portions of all bars.          Alternate bars and eventually the coupling shaft and/or corresponding portions of the second coupling system are preferably reciprocable lengthwise of the remaining bars to allow for convenient expulsion of particles of foreign matter which happen to penetrate into the clearances between neighboring bars.

Abstract: Abstract of the Disclosure A clutch interposed between a hub mounted for rotation on a spindle and a selectively driveable axle which extends longitudinally through the spindle serves to engage the hub to the axle when the clutch is subjected to torque caused by placement of the axle in a dynamic or driving axle mode.  When the axle is in a passive or non-driving axle mode the clutch serves to disengage the hub from the axle whereby the hub is free-wheeling on the spindle.

Abstract: ABSTRACT OF THE DISCLOSURE            In an inplantable breast prosthesis of the type intended to be inflated with liquid there is a self-sealing valve for adjusting the liquid volume in the prosthesis.  The valve is thimble-shaped, the open end being guarded by a self-sealing gel plug which receives the needle of a hypodermic while the closed end acts as a stop preventing further insertion of the needle which might otherwise puncture the prosthesis. The contents of the hypodermic reach the prosthesis interior through apertures in the valve which lie normal to the direction of needle entry.          A method of post- implantation treatment consists of adjusting the dose of steroid in the interior of the prosthesis.

Abstract: D-20,684 DIGITALLY PROGRAMMABLE ACTIVE RC BANDPASS FILTER WITH CONSTANT ABSOLUTE BANDWIDTH   by Gideon Willoner ABSTRACT OF THE DISCLOSURE         A narrow-band RC active bandpass filter, in which the center frequency may be changed by changing the resistance values of certain resistive elements, has the certain resistive elements switchably connectable into and out of the RC network so that the ratio of time during which the resistors are con-nected to the network to the time during which resistors are not connected to the network determines the effective resistance thereof.  A programmable timing circuit has a plurality of outputs with each output supplying a different number of equal width pulses during a predetermined like time period whereby each output corresponds to a different ratio.  The timing circuit actuates and deactuates the switchable connection from a selected output thus deriving the required effective resistance for a prede-termined center frequency.  The bandwidth of the passband is set by a different resistive element and remains substantially unchanged as the center frequency is changed by changing the effective resistance of the certain resistive elements.

Abstract: ABSTRACT           A method for automatically controlling the width of a steel slab during hot rough-rolling thereof involves arranging a pair of horizontal broadening rolls each having at least one annular projection in a hot roughing mill train comprising a plurality of roll stands.  A roll gap correction of the pair of broadening rolls is calculated on the bases of the variation in the width of the slab during hot rough-rolling on the hot roughing mill at the entry of the pair of broadening rolls.  The roll gap of the pair of broadening rolls is controlled in response to the amount of roll gap correction, thereby automatically controlling the width of the slab during hot rough-rolling thereof to a pre-scribed value at a high accuracy in accordance with the finishing width of a steel strip which is to be manufactured from the slab.         At the same time, variations in the width of the slab during hot rough-rolling thereof are automatically corrected to a high degree of accuracy.
