Abstract: ABSTRACT OF THE DISCLOSURE      Hydraulic systems comprising master and servo cylinder assemblies are sometimes bled only with difficulty, and even then not effectively.        The invention provides a method of bleeding such systems, which involves the introduction of hydraulic fluid into the servo cylinder via a hydraulic connector having a fluid feed passage and a non-return valve therein.          The fluid passes from the servo cylinder into the master cylinder. The hydraulic connector has engaging means for engaging with a connecting member of a hydraulic fluid feed line. A removable dust cap co-operates with the engaging means to seal off the passage and to protect it against dust and foreign matter when the engaging means is not connected to the connecting member.

Abstract: ABSTRACT OF THE DISCLOSURE     A distributor for distributing a fluid into the volume of a fluidized bed contained in a vessel comprises a base member in which are mounted upstanding nozzles having outlets for directing the fluid horizontally away from the nozzles into the volume of the bed, the outlets of same nozzles being arranged at a lower level than the outlets from other nozzles so that fluidizable bed material will be fluidized above a contour substantially defined between the outlets of the nozzles.          Thus, there will be a "well" or depression in the contour around each nozzle, and the  contour will extend to just below the outlet of each nozzle.   The  contour may be formed by the upper surface  of unfluidized d fluidizable material (e.g.,from the bed) or by the upper surface of non-fluidizable material (e.g., blocks of refractory cement or metal sheeting) which may constitute at least part of the base  member.   Another fluid may be passed into the volume of the fluidized bed by providing conduits whcih extend  horizontally beneath the contour (e.g., for protection from the  fluidized bed) except for one end which extends into the volume of the wells or depressions.   The other end is preferably outside the distributor and the conduits are preferably straight and withdrawable from the distributor.

Abstract: ABSTRACT           Bit rate compression in a digital communications system is provided by transmitting voice information from n telephone circuits over the capacity conventionally allo-cated for transmission of voice information from n/2 circuits without appreciable degradation in quality.  Alternatively, a doubling of the number of voice circuits may be provided with transmission at the same bit rate required for conventional transmission of voice information.  Each frame period, at the transmitter, all n circuits are serviced and, utilizing an adaptive predictive encoding scheme, a maximum of only 3/8 n unpredictable samples in the given frame are transmitted over the available channel capacity.  A sample assignment word (SAW), which identifies the circuits corresponding to the unpredic-table samples, is transmitted therewith.  Upon reception of the transmitted frame comprising the SAW and the unpredictable samples, the receiver updates the stored samples which were transmitted during previous frames as unpredictable samples by substituting the received unpredictable samples for the stored samples in accordance with the channel routing information provided by the SAW, thereby enabling proper reconstruction of all samples in the given frame.  Means are provided for effectively recirculating the servicing sequence of the n circuits to optimize the adaptive predictive encoding scheme.

Abstract: ABSTRACT           A moisture-containing viscous secondary fuel is combusted in the chamber of an industrial furnace by comminuting the secondary fuel to a particle size of 5-50mm and propelling the particles at an initial speed of 1-10m/sec. onto a layer of intensely burning pri-mary fuel, such as solid refuse, coal or wood.  The particles are propelled from a level at 0.5-2m above the burning layer and in such a way that the length of their flight spans is 0.2-2m.  This insures that the particles retain moisture during travel in the combustion chamber and do not agglomerate prior and/or subsequent to contacting the burning layer of primary fuel.  The rate of admission of commi-nuted secondary fuel is regulated in dependency on changes of temperature in the chamber,  in dependency on changes of the CO2 or O2 content of combustion products and/or in dependency on variations of a parameter (e.g., length) of the burning layer of primary fuel.

Abstract: WEIGHING SYSTEM FOR CONVEYING MEANS               Abstract of the Disclosure A forage conveyor-scale apparatus includes a pivoted conveyor having a differential transformer load cell providing a weight signal.  A Hall cell unit is coupled to the conveyor to produce a speed signal.  An automatic gain amplifier is controlled by the speed signal to vary the energization of the transformer from an oscillator.  The output voltage of the transformer is rectified and averaged to produce a DC analog rate weight signal which is connected to drive a rate weight BCD counter and a total weight BCD counter.          The analog signal drives a triggered integrator to form a pulse train driving the total counter.  A dual slope integrator is controlled by the analog signal to cyclically control the weight rate counter.  A single readout is provided and connected to the rate weight counter.  The output of the total counter is forced through the rate weight counter to the readout to display the total count.  A comparator may respond to a present input and total counter to automatically terminate delivery.
