Abstract: Abstract of the Disclosure This invention relates to an automatic precision apparatus which includes an elongated rotatable central shaft concentric with and encased by a fixed outer cylinder.  A rotary workpiece table is fixed to the central shaft adjacent one end of the central shaft, and a round tool holder table is fixed to the cylinder adjacent one end of the cylinder and dis-posed in spaced relationship with the rotary table and in parallel arrangement with the rotary table.  A plurality of spaced tool holders are disposed around the round table, and a plurality of equally spaced workpiece holders are disposed on one surface of the rotary table facing the round table.     Each tool holder is precisely aligned with a respective one of the workpiece holders and is alignable with every other one of the workpiece holders.  In one embodiment of the invention, a piston and cylinder arrangement is provided for moving the shaft to a second position relative to the cylinder from a first position relative to the cylinder, and from the second position back to the first position, and a further piston and cylinder arrangement is provided for rotating the shaft relative to the cylinder when the shaft is in the first position relative to the cylinder.  An indexing arrangement, consisting of two parallel plates with facing surfaces having a plurality of indentation groups spaced therearound, pairs of indentation groups being aligned with each other, and insert means between the indentation groups is provided for releasably attaching the shaft to the cylinder when the shaft is in the second position relative to the cylinder.         Thus, when the shaft is in the first position, the rotary table is rotatable, with the shaft, relative to the round table, which is fixed to the cylinder, to move each work-piece holder from their positions adjacent one of the tool holders to a new position adjacent another one of the tool holders.  Further, when the shaft is in the second position, a closed vibration path is provided from each workpiece, through its respective workpiece holder, through the arrangement for releasably attaching, through the cylinder, through a respective tool holder adjacent each workpiece holder, through the tool in the respective tool holder and back to the workpiece.

Abstract: PROCESS FOR PRODUCING SILICON CONTAINING FERRO ALLOYS   Abstract of the Disclosure A process for producing silicon-containing ferro alloys consists in preparation of a charge comprising quartzite and a briquetted mixture of an ore carring an alloying element of the alloy to be produced with a carbonaceous reducing agent, charging the resultant charge into a smelting furnace and subsequently carrying out a continuous one-stage melting. The process is characterized by a defficiency of a carbon content in the carboneous reducing agent, which defficiency being 1.03 to 1.25 times  as low as that sufficient for the reduction of all the elements in the charge, and an excess of a carbon content, which excess being 2 to 15 times as high as that sufficient for the reduction of the alloying element.      The process provides for elimination of both slagging and carbide depositing in the smelting chamber of the furnace, makes it possible to reduce power consumption and to extend the range of commercial grades of ferro alloys thus produced.

Abstract: ABSTRACT OF THE INVENTION            Apparatus and method are disclosed which pertain to inflatable structures useful as air beds and the like.  Shape and load con-trol are facilitated by a plurality of bladders that are located within an inflatable chamber of the structure and are joined to opposed imperforate walls thereof.  The bladders are provided with vents which lend to the interior of the chamber, and upon inflation of the structure and resultant separation of the opposed walls of the chamber, the bladders are caused to extend from a flattened state, become filled with the fluid used for inflating the structure, and assume a roughly cylindrical con-voluted configuration.  Being made of a flexible, substantially non-extensible material, such as vinyl plastics, there is a limit to which the bladders can extend, and further vertical separation or lateral shifting of the attached opposed walls is thereby restrained.  When the bladders are provided with vents, they "breathe" when a physical load is applied to the inflated struc-ture or removed from it, hence, regulating resiliency by means of an "air spring" effect.

Abstract: ABSTRACT OF THE DISCLOSURE         Relative shive incidence in a production flow line of paper pulp is continuously sampled and measured by means of a continuous flow, fiber induction device located within the pro-duction line to extract a diluted sample of fiber flow therein.          The diluted sample is directed through a windowed conduit section for photodetection of particles therein.  Particle caused pulses are discriminated by amplitude relative to a reference scale to distinguish shive particles from acceptable fiber particles.  Two pulse trains are developed simultaneously:  one pulse train for shive pulses and the other pulse train for particle flow including shives.  Both pulse trains are rate determined by counting the number of pulses in a fixed interim of time identi-cal to both.  The two pulse rates are then combined to develop dimensionless ratio of shive incidence or percentage within the total fiber stream.

Abstract: ABSTRACT OF THE DISCLOSURE   To limit the accumulation of recursive computation errors while recursively calculating the discrete Fourier transform of an input signal in re-sponse to moving window sample sets of that signal, the dependent variables for the recursive calculations are periodically refreshed. One embodiment generates an error limited continuous discrete Fourier transform of the input signal through the use of duplicate channels which are periodically reinitialized in time staggered relationship and alternately switched on-line and off-line in timed synchronism with the reinitialization process. Each of the channels of that embodiment is equipped to recursively calculate the discrete Fourier trans-form of the input signal so that while one channel is on line feeding recursively calculated transform coefficients to the output, the other channel or channels are off-line being reinitialized and then computing fresh sets of transform coefficients for subsequent on-line recursive calculations. Another embodiment performs essentially the same function through the use of an on-line main processing channel which recursively calculate the discrete Fourier transform coefficients of the input signal on the basis of successive sets of dependent variables which are computed in and supplied by a periodically reinitialized off-line auxiliary processing channel.

A central node, or repeater, is employed, with all trans-missions to it being performed at a first frequency, and with the frequency division multiplexing being such that all re-transmissions from the central rode are performed at a second, different frequency. The noise codes employed are of a type termed code mates having correlation functions which upon detec-tion provide an impulse autocorrelation function. The described arrangement enables random access, or direct call-up, to be accomplished with total non-interference between users. Large improvements in signal-to-noise power ratio and in signal-to-jamming power ratio will be seen to result.

Abstract: ABSTRACT OF THE DISCLOSURE Copolymers of acrylic or methacrylic materials of known type and reacted with novel, silicone-substituted acrylic and methacrylic compounds so as to produce an oxygen-permeable plastic material which is uniquely suitable for manufacturing novel corneal contact lenses. The silicone materials include high molecular weight polysiloxanylalkylesters of acrylic and methacrylic acids, made from acrylic or methacrylic ester silanes containing one or more highly substituted siloxanyl groups. One such siloxane substituent, pentamethyldisiloxane, is prepared by a novel method. Certain of the substituted silanes are prepared using a novel compound, tris(trimethylsiloxy) acetoxysilane. The polymers made from the combination of novel znd known monomers are highly permeable to oxygen and can be used to make lenses, including bifocal lenses, which are thick enough to be rugged, hard enough to provide dimensional stability, and optimum optical correction, and sufficiently permeable to oxygen to provide extended duration wearing capabilities. A number of novel monomers are disclosed. The polymers may be made from known monomers and individual novel monomers, or from the known monomers or mixtures thereof and mixtures of the novel monomers. The finished polymers may also include conventional additives such as wetting agents and cross-linking agents.
