Abstract: ABSTRACT OF THE DISCLOSURE        A control device having a pressure sensing element coupled to a balance plate.  The balance plate, in turn, is coupled to a microswitch by an actuating rod.  Variations in pressure displace the sensing element which, in turn, pivotally displaces the balance plate sequentially about first and second axes.  A pair of springs are coupled to the balance plate. The bosses facilitate use of identical springs and adjusting members in a control device where the differential between control points if fully adjustable.  The control device has a housing including upper an lower sections, the upper section having a microswitch associated therewith, the lower section having the balance plate and associated elements disposed therein.  A re-cessed space at the  exterior of the housing is defined by the upper and lower housing sections.  The adjusting member for the springs extend into the recessed space so as to be readily accessible from the exterior of the housing.  The control device includes a detectable pressure transducer which facilitates con-version of the control device from one application to another.

Abstract: ABSTRACT OF THE DISCLOSURE           An extruder is operated continuously to produce a plastically deformable strand that is pulled through a calibrating die and a cooling bath by a withdrawal arrangement downstream of the die and the bath.  A sensor detects the volume of the strand between the tool and the extruder and controls the extrusion or the withdrawal rate in accordance with such volume so as to produce an accurately calibrated extrusion.  The sensor may engage the strand at the bank formed immediately upstream of the mouth of the calibrating die or may be upstream therefrom and detect the hang or droop of the strand between the die and the extruder.

Abstract: SINGLE ELEMENT PRINTER             Abstract of the Disclosure A printer has a carrier having a rocker which supports a print shell on which are disposed type characters in a two dimensional array with the shell controllably movable in two degrees of freedom (rotate and tilt) to selectively position each type character opposite a record-medium-carrying platen for printing. The rotation is per-formed by a motor on the rocker and directly connected to the print shell.  The tilt is performed by a motor on the carrier and connected via a particular link configuration to the print shell.  In addition, during printing the shell is driven against the platen with a force related to the particular character being printed by virtue of a controllably rotatable shaft which via a cam drives the rocker.

Abstract: COMBINED ENCODER-DECODER APPARATUS    HAVING A SINGLE ACTIVE FILTER     ABSTRACT    A combined encoder-decoder for use in two-way radio systems.          The apparatus is operable in an encoder mode to provide tone oscillations during operation of the radio apparatus in the transmit mode and also in a decoder mode to provide a control signal in response to a received tone signal of a particular frequency during operation of the radio apparatus in the receive mode.  The encoder-decoder includes a single active filter and a feedback circuit selectively coupled to the filter to form an oscillator for producing the tone oscillations in the encoder mode of operation.  An input amplifier/limiter is enabled to apply received tone signals to the active filter during decoder operation.  A control circuit responsive to operation of the radio apparatus is coupled to the feedback circuit and to the input circuit so as to selectively enable the feedback circuit during encoder operation and the input circuit during decoder operation.  The control circuit causes the feedback circuit to provide increased gain upon initiation of encoder operation so that oscillations build up rapidly.          The output of the active filter is applied to a detector to which two integration circuits are connected, the first being enabled during encoder operation and the second during decoder operation.  The first integration circuit responds when the signal builds up to control the feedback  circuit to reduce the gain to the desired level.  The second integration circuit is enabled during decoder operation so that when the signal of a particular frequency is applied to the active filter a control signal is produced which is utilized to enable the audio circuit of the receiver.  The control circuit also responds to the switching of the circuit between encoder and decoder modes of operation to increase the bandwidth of the active filter to prevent encoder tone overshoot during the receive-transmit transition and to prevent decoder falsing during the transmit-receive transition.

Abstract: ELEVATOR CONTROL APPARATUS            ABSTRACT OF THE DISCLOSURE         In an elevator system comprising a plurality of elevator cars serving a plurality of floors in response to hall calls and cage calls, an elevator control apparatus is provided which comprises a device for forecasting cage calls as a new type of traffic in-formation expected to be registered as hall waiting passengers take a given car.  The device includes means arranged on each hall for detecting the number of prospective passengers waiting on the particular hall and means for setting the ratios of the hall waiting passengers destined for respective floors. The detected number of hall waiting passengers is multiplied by the ratios of destination floors (hereinafter referred to as "destination ratios") to figure out floors to which the hall waiting passengers joining the car are most likely to pro-ceed, thus forecasting a corresponding cage call or calls.  This cage call forecasting device is used in an elevator control system assigning hall calls, so that a cage call expected to be registered by the serving of a hall call is forecast at an early time.  The waiting time required until each car reaches each floor, for example, is thus forecast with high accuracy taking into consideration cage calls expected to be registered in the future.

Abstract: ABSTRACT OF THE DISCLOSURE   A heat soaked polymer by-product from the production of gasoline using a 90-400°F. steam cracker naphtha as feed is converted to an aromatic hydrocarbon oil or to a naphthenic hydrocarbon oil by first subjecting the same to a thermal polymerization and then subjecting the thermal polymerization product to a hydrotreating or hydrogenation step or both.  Generally, the hydrotreatment is accomplished at relatively mild conditions so as to avoid any change in aromatic ring structure.  Hydrogenation, on the other hand, is accomplished at more severe conditions so as to effect hydrogenation of the aromatic rings.
