Abstract: ABSTRACT OF THE DISCLOSURE         A visual display device is featured which uses a new thermal addressing technique to provide a dark image upon a lighter background.  The display is capable of being mutliplexed to a large number of rows   The device comprises a cholesteric-smectic liquid crystal material mixed with a pleochroic dye of high order parameter.  When the material experiences a transition from a higher to a lower, smectic thermal phase, two different textures or light states are developed; a transparent state and a light absorbing state.  The transparent state is developed by applying a sensitizing voltage to certain portions of the medium.          The pleochroic dye absorbs the light passing through the unsensitized portions of medium to provide the dark image.  The row electrodes are made diffusely reflective so as to provide a double light pass through the medium to improve contrast.

Abstract: ABSTRACT        Apparatus and method of positioning and seating a retrievable insert landing assembly in a well bore tubular member with a left hand threaded portion and having a sealing bore  above  or below the  threaded portion.   A releasable connecting arrangement secures the landing assembly in a well bore tubular member by engaging with the left-hand threaded portion in the tubular member.  The landing assembly has an internal polished bore above the connecting arrangement which slidably and sealingly receives a tubular extension attached to a well string.  The connecting arrangement is actuated by lowering the retrievable landing assembly within the tubular member to position the connecting arrangement adjacent the left-hand threaded portion and then lifting up on the landing assembly to lock it with the left-hand threaded portion.  The well string is manipulated to actuate the releasable coupling and disconnect the well  string  from the  landing  assembly after it is connected with the tubular member.   To retrieve the  landing  assembly,  the well  string  is  manipulated  to reconnect it with the retrievable landing assembly.  The well string  is  then  manipulated  to  actuate  the  connecting arrangement to disconnect the retrievable landing assembly from the tubular member so that it may be retrieved.   Thus, the retrievable insert landing assembly is mechanically set and  mechanically retrieved merely by manipulating the well string on which the landing assembly is lowered into the well bore.

Abstract: CURRENT CONTROL METHOD AND CIRCUIT FOR    ELECTRONICALLY-COMMUTATED MOTORS                 ABSTRACT OF THE DISCLOSURE         Techniques for controlling motor winding current by employing ON/OFF duty cycle control switching between an upper and a lower current threshold to establish an average motor winding current approximately midway between the two thresholds.  Rising current during ON time intervals is directly measured, and an upper threshold detector is employed to turn OFF a switching transistor when the upper current threshold is reached.  Rather than directly measuring decay or fly back current which circulates in the motor windings through free-wheeling diodes for comparison against the lower current threshold, the decay time is simulated.  A lower current threshold detector and an upper current threshold detector are employed.  Following winding energization, the lower threshold current detector starts a timing device. The upper threshold current detector subsequently stops the timing device, and turns OFF the switching transistor.  Winding current then decays, and the decay time needed to reach the lower threshold is simulated by waiting for a decay time interval which is a function of the measured rise time interval.

Abstract: ABSTRACT OF DISCLOSURE           Hard coatings are applied to substrate metals by coating the metal surface, e.g. by dipping the substrate metal in a molten alloy of the coating metals, and then exposing the coating at an elevated temperature to an atmosphere containing a reactive gaseous species which forms a nitride, a carbide, a boride or a silicide.  The coating material is a mixture of the metals M1 and M2 of which M1 forms a stable nitride, carbide, boride or silicide under the prevailing conditions and of which M2 does not form a stable nitride, carbide, boride or silicide.  M2 serves to bond the nitride, etc. of M1 to the substrate metal.          Mixtures of M1 and/or M2 metals may be employed.  This method is much easier to carry out than prior methods.

Abstract: FREE-FALLING, SELF-LOCKING ADJUSTABLE TIP ASSEMBLY             ABSTRACT OF THE DISCLOSURE An improved tip assembly which includes a tongue plate insertable into a buckle is provided for a safety belt apparatus in which a continuous retractable belt length provides both a lap portion and a shoulder portion.  The tip assembly through which the belt passes has a snubber slide engaged with the tongue plate and slidable relative thereto.  When the belt is drawn by the passenger over his body, the belt shifts the snubber slide rearward on the tongue plate to where the belt is firmly gripped at normal loads between a surface of the tongue plate and a surface of the snubber slide, whereby that portion of the belt which extends across the passenger's lap cannot expand.  At heavy deceleration loads, e.g. 150 lbs on the lap belt, a portion of the snubber slide deflects to decrease the gripping action to allow transfer of belt from the shoulder belt into the lap belt.  When the belt is retracted so that a run of the belt is substantially vertical, the weight of the tip assembly causes its front end to tip downward causing the slide to fall forward along the tongue plate releasing its grip on the belt, whereby the tip assembly freely falls to a lower position along the vertical belt run.
