Abstract: ABSTRACT OF THE DISCLOSURE           In a method and device for producing fibre pulp from fibrous lignocellulose containing raw material, such material is subjected to preheating in a preheater by means of steam and thereafter to grinding at increased pressure of steam or gas between grinding discs which rotate relatively to one another in a grinding apparatus into fibre pulp which is propelled from the apparatus housing by means of the steam or gas into a separation device which is similarly maintained under steam pressure and in which the steam is separated from the pulp.  The material is con-veyed not only to the preheater but also from the latter to the grinding apparatus via a steamtight conveyor.  An increased pres-sure of steam or gas is created at this stage in the grinding apparatus compared to that in the preheater such that the steam proceeding from the grinding apparatus to the receiving device is conveyed further by means of this higher pressure to the pre-heater, there being responsible for preheating the material to over 100°C.

Abstract: ABSTRACT OF THE DISCLOSURE An exemplary embodiment of the invention utiliz-ing the video channel of a TV signal to transmit synchro-nizing codes for an audio scrambler.  Scrambling of the audio is accomplished by digitizing the audio and adding to each sample a pseudo-random digital number.  The result-ing  digital  numbers  are  converted to  analog  form  for transmission.  A digital signal specifying the  starting point of the pseudo-random number generator is inserted into the video portion of a line of the vertical blanking interval of the TV signal.  At the receiving station, the digital number specifying the starting point of the pseudo-random number generator is utilized to set the starting point of a pseudo-random number generator which generates numbers which are utilized to descramble the audio.

Abstract: ABSTRACT: Optical waveguide terminating apparatus applies a pair of connectors of the type comprising plug members having metal retention sleeves therein to the ends of an optical waveguide cable having the jacket stripped to expose the fiber. Plug members are delivered to an insertion station attached to a metal carrier strip and are clamped securely between an upper clamp and an anvil which move together vertically under the action of followers riding in cam slots in a moving cam block which also determines movement of other components. Cable is positioned relative to insertion station by aligning exposed fibers in narrow channels in top of shear bar and aligning jacket in primary cable guide channels in guide block adjacent the shear bar which has a slot therein through which said strip passes. The shear bar drops to shear the strip from sleeves and aligns a secondary cable guide channel above fiber guide channel in block with primary channel. Two pairs of cam actuated jaws grip the cable and advance the ends through channels toward the insertion station. The channels drop away during this advance to permit the jaws to fully insert the cable ends in the plug member as the jaws push retention sleeve fully into plug member to seat it on lances on the sleeve. Resilient springs bear on the jaws so that cable ends are pulled back to seat them on lances in the retention sleeves.

Abstract: Abstract A balanced modulator, producing a double sideband suppressed carrier (DSBSC) output achieves carrier suppression and linear performance suitable to modulate frequency division multiplexed signals with stringent interchannel interference requirements.  It is simply and inexpensively realized through the use of two logic gates which are arranged in a dual complementary fashion and which drive a center-tapped transformer through coupling capacitors to provide the required switching function necessary to produce the DSBSC output.  The modulator circuit has the added feature that the square wave carrier source that is applied to the logic gates can be the means of activating the circuit, thereby eliminating the need for a separate power supply.

Abstract: SIGNAL REPRESENTATION GENERATOR   Abstract of the Disclosure An apparatus and method for generating a representation of an arbitrary signal wherein the signal is represented as a sum of reference signals derived from a standard wavelet defined on a grid in the frequency-time plane.  The apparatus comprises a plurality of octave circuits, each octave circuit, in turn, comprising a plurality of band circuits that divide a frequency range covering the spectrum of the signal into equal intervals of logarithm of frequency.  Each band circuit comprises a bandpass filter to select a frequency component of the signal and a correlator to correlate the signal component with a reference signal derived from a standard wavelet to produce a series of correlation values representing the signal for recordation in response to clock pulses received by the octave circuits. The octave circuits are clocked at rates which increase by a factor of two with increasing octave of frequency with which the octave circuits are associated so that correlation time intervals decreasing by a factor of two for successively higher frequency octaves are defined for all frequency bands within each octave and one correlation value is associated with each octave and one correlation value is associated with each frequency band and with each correlation time interval to effect the representation.
