Abstract: ABSTRACT             An apparatus in a digital communication system for receiving and/or transmitting link control bytes of eight bits or in the alternative information bytes of any number of bits.  Dynamic switching to different byte size in an information field is accomplished by utilizing a logic control field (LCF) as part of a message received or trans-mitted, comprising 8-bit bytes which are recursively extendable.      The first octet of the LCF is a text control byte for identifying the number of bits in each byte contained in the accompanying text field transmitted or received, whereas the last LCF octet is indicated by setting the most significant bit (MSB) of the octet to 1.  Apparatus responsive to the above fields for accomplishing the transition is disclosed.

Abstract: Abstract of the Disclosure:          A method and apparatus are provided for blocking the re-ception of a subscription television program signal while substitut-ing for the blocked signal a replacement program signal which is received by the blocked receiver.  A single radio frequency signal, serving as an interfering carrier, is provided intermediate the audio and video carriers of the subscription signal and is modulated with a substitute audio and/or video program signal.  The frequency of the interfering carrier is selected so that beat frequencies (i.e. sum and difference frequencies with carrier frequencies of the subscrip-tion program), which result from the non-linear characteristics of a conventional television receiver, or harmonics of the beat frequencies which are similarly produced, will block reception of the subscription television signal.  These non-linear receiver characteristics also produce replicas of the interfering carrier modulation in the bands of the normally detected audio and video intermediate frequency signals in the receiver and these replicas replace the blocked subscription television program and are reproduced by the receiver.        At an authorized receiver, there is provided a band-elimination filter, or the like, which is placed ahead of the receiver and is tuned to the interference carrier.  As a result, the modulated interference carrier is removed prior to being applied to the receiver, so that the subscription television program can be received in the usual manner at the authorized receiver.

Abstract: VERTICAL FORM, FILL AND SEAL PACKAGING            MACHINE WITH IMPROVED SIDE SEALING MEANS                    ABSTRACT OF THE DISCLOSURE A vertical form, fill and seal packaging machine has a tube former for receiving flexible packaging material in thin flat strip form and juxtaposing opposite longitudinal edge por-tions thereof in parallel vertically extending relationship to provide a depending tube open at the top.  An end sealer provides vertically spaced horizontally extending transverse or end seals across the tube.  A product dispenser discharges measured quantities of product into the tube interior through its open upper end.  Tube feed means comprises first and second pairs of vertically spaced rolls respectively on opposite external sides of the tube of packaging material and first and second tube feed-ing belts respectively trained over said pairs of rolls.  Inner runs of the belts engage the tube and have vertically extending perforate portions.  Vacuum generating means communicate with the perforate portions to cause the belts to grip the tube and back-up means within the tube provide for frictional tube feeding action.  Improved side sealing means comprises a third pair of rolls spaced vertically along the longitudinal edge portions and a belt trained thereover and in pressure engagement with the edge portions.  Back-up means within the tube react the sealing belt pressure.  The sealing means is driven in unison with the tube feed means and is both adjustable toward and away form the tube edge portions and movable bodily away from the edge portions to prevent overheating thereof.

Abstract: ABSTRACT OF THE DISCLOSURE        A housing assembly for a wedge type disc brake in which the wedge actuator is housed in a radially disposed aluminum housing member which is clamped between the inboard end of a ferrous caliper housing member and a ferrous end plate by axial bolts passing through the end plate and the aluminum housing member for threaded engagement with bores in the inboard end of the caliper housing.  The inboard face of the aluminum housing member has an opening opposite the wedge actuator which is closed by the end plate so that the inboard rollers of the roller bearing assembly interconnecting the wedge actuator and the push rod bear directly on the outboard face of the end plate.  The braking force generated at the interface of the wedge actuator and the push rod is thus transferred to the end plate and absorbed by tensioning of the bolts, thereby relieving the aluminum housing of any significant tensile loading.

Abstract: ABSTRACT OF THE DISCLOSURE A method for forming a turbulent suspension from a pulverous material and reaction gas by causing the pulverous material to flow downwards as an annular flow into the reaction chamber and by directing the reaction gas downwards inside the annular flow of the pulverous material, in which the suspension is produced by bringing the reaction gas into a high-force rotary motion and by then causing it, throttled, to discharge into the reaction chamber so that in the reaction chamber it meets on its outside a substantially vertically downward annular flow of the pulverous material, this flow being formed by utilizing the kinetic energy of the falling pulverous material on a convergent conical glide surface.  An apparatus for forming a turbulent suspension from a pulverous material and reaction gas, which apparatus is adapted to be directed centrally downwards into the reaction chamber and consists of a feed pipe for the pulverous material, means for dividing the pulverous material and of a turbulence chamber for reaction gas, in which the feed pipe for the pulverous material has the shape of a downwards convergent cone, and inside the feed pipe there is an axially mounted turbulence chamber at the upper section of which there is a turbulence generator, and the lower section of which there is a turbulence chamber comprises a cylindrical stabilizing member with a diameter less than that of the turbulence chamber.
