Abstract: INTERLEAVED DIGITAL DATA AND VOICE   COMMUNICATIONS SYSTEM APPARATUS           AND METHOD                       Abstract The disclosed invention allows digital data to be integrated with a digital voice signal in a simple manner that does not affect the voice transmission quality.  Digital data is inserted in quiet or "no speech" portions of the voice signal stream when such quiet periods are detected. No flags, headers, or other indications are necessary upon the insertion of digital data.  The digital data is encoded in a two byte pattern in which the scaling bits are set high and the sign bit alternates in each eight bit byte.  Four bits of each byte are thus reserved for scaling and sign purposes, but the remaining four bits are available for data transmission.  Setting the three scaling bits high and alternating the sign bit has the effect of indicating to the receiver that voice is not present.  This is so because the scaling bits and alternating sign bit will be decoded under the PCM coding technique to indicate an out of scale four kilohertz tone that is not allowable within the transmission path requirement of the Bell System or the CCITT in Europe.  Recognition of such a signal by the receiver permits a detector to block the output at a speech terminal and to strip the scale bits from the input two byte patterns and pass the remaining bits as data to a data output.

Abstract: Abstract of the Disclosure A terminal device capable of preparing a document and communicating data includes a system control section having storage means in which are resident a control program for outputting received document data either to an output section or an external storage, and a supervisor program for alternately practicing the control program and another program necessary for system control.  Based on these resident programs, the system control is practiced to permit received document data to be fed to the output section or the external storage even when local work such as prepara-tion of a document is under way.  When printing operation is disabled due to a failure in a printer of the output section or the like after the received document data has been loaded in a memory of the communication control, the document data is immediately delivered to the external storage to open the document data storage area.  Power is supplied only to the equipments which are indispensable for storing received document data in the memory, except for the duration of any local work such as preparation of document data.

Abstract: OPEN CIRCUIT CURRENT TRANSFORMER                 PROTECTION CIRCUIT Abstract Of The Present Invention A three-phase power supply has a current trans-former in each power line.  The transformer secondary winding is connected to a load.  Generally, the load is a control means responsive to the current being sensed.  A triac in parallel with the secondary winding and load has its gate connected by a voltage sensitive circuit to sense the corresponding secondary winding voltage and to conduct and protect the transformer in the event of load loss.  The gate circuit includes a metal oxide varistor and a linear resistor in series connected in parallel with the secondary winding.  A second linear resistor is connected to the common node of the first linear resistor and metal oxide varistor.  The second linear resistor is in series with a diac and connects the gate to the common node of the var-istor and first resistor.  A trigger capacitor is connected between the common node of the second resistor and diac and the opposite end of the first linear resistor.  On load loss, the secondary voltage rises and the varistor conducts, rapidly charging the trigger capacitor.  The diac then conducts and the trigger capacitor supplies a large but controlled gate current to drive the triac "on."  During the opposite half cycle, this cycle repeats until a load draws enough current to keep the secondary voltage within a critical level.

The vessel and fall plate are progressively transported from one end of the mould to the other to lay down partially expanded foam over the bottom of the mould (Figure 1).   The ends (11,12) of the mould may be opened to permit entry and exit of a foam lay-down unit (6) and transporting means (7) and to permit removal of the expanded foam strand (61) (Figures 6 and 7).

Abstract: ABSTRACT OF THE DISCLOSURE An improved chute for a bale loader which enables a quarter-turn rotation of faulty positioned bales prior to loading of the bales.  A wheel rotatably mounted on the forward most end of one of a pair of converging arms on the chute is operable to engage the side of a bale of hay, straw, or the like.  The wheel, being rearwardly and inwardly inclined toward the bale-receiving channel defined by the conveying arm members of the chute causes one quarter ro-tation of the bale.  The wheel is of proper size to allow the operator of the loader to selectively engage only those bales requiring rotation.  The wheel may be spring mounted to minimize repairs and may be driven by an external power source.
