Abstract: ABSTRACT OF THE DISCLOSURE           In a radio communication system having a transmitter at a first location for sending binary messages to a receiver at a second location, it is necessary that the receiver be synchronized with the binary message so that the start or beginning of the message can be accurately deter-mined.  This synchronization is provided by synchronizing words spaced in each binary message, each synchronizing word having a predetermined sequence of binary values.  If a receiver receives two synchronizing words having the predetermined binary values, it produces an in-synchronization signal so that messages will be properly received.  If, after the in-synchronization signal is provided, a pre-determined consecutive number of synchronizing words failing to have the predetermined sequences are received, then the receiver produces an out-of-synchronization signal. The in-synchronization and out-of-synchronization signals provide reliable operation of receivers which receive binary messages.

Abstract: ABSTRACT OF THE DISCLOSURE      A basket, with no movable parts, for holding and dis-playing goods is provided with opposed bails at the upper end and support feet at the lower end, constructed and arranged to provide secure but separable stacking character by a separable interconnection of bails and feet of two sim-ilar baskets, wherein the basket construction effects resilient snap-together and locking of bails and feet to provide a stacking, or columnar, arrangement with great stability.  Addi-tional safety means to prevent inadvertent unstacking is pro-vided by cooperating elements on the baskets.  Two baskets may be nested, for reducing volume occupied by baskets when stored or shipped, by use of interfitting such baskets in an inverted and offset arrangement that is accommodated by slots defined adjacent basket corners.  A base basket and support base com-bination provides a very stable construction, that may have additional baskets stacked in a column upon the base basket, by use of wire elements that are shaped and arranged to interfit for maximizing resistance by the base basket to tipping relative to its support base.

Abstract: SPEED-CHANGING DEVICE FOR TOOLS HAVING A GEAR ASSEMBLY WITH A VARIABLE GEAR RATIO                     ABSTRACT OF THE INVENTION           The invention is directed to a speed-changing device for a tool having a gear-box housing and a gear assembly arranged in the housing.  The gear assembly has a gear cluster which is movable between at least two positions for changing the gear ratio of the gear assembly.  The speed-changing device includes an annular guide member adapted to snap into an opening in the gear-box housing for firmly holding the device in the housing.          A cylindrical member is rotatably mounted in the annular guide member and defines a longitudinal axis of rotation.  A head piece is securely mounted on the cylindrical member and has an elongated projection extending therefrom eccentric to this axis.          The elongated projection engages the gear cluster to move the same from one position to another in response to a manual actuation of the cylindrical member.  The cylindrical member is configured to contact the guide member to conjointly define there-with a sealing interface.  A resilient member is interposed between the head piece and the guide member for resiliently loading the cylindrical member with respect to the guide member thereby causing the cylindrical member to press against the guide member at the sealing interface whereby an effective seal between the members is established to prevent lubricating liquid from flowing out between the members from the gear-box housing.

Abstract: ELECTRICAL STIMULATION SYSTEM            ABSTRACT OF THE DISCLOSURE         An electrical stimulation system for selectively stimulating portions of the body.  The system includes an external device for alternately transmitting stimulus sig-nals and control signals to an implantable receiver.  The receiver includes a plurality of output devices adapted to apply the stimulus signals to the body and circuitry for routing the stimulus signal  to the output devices under the control of the control signals.  In a preferred embodiment, the control signals are formed of an alterably preselected number of pulse signals with the routing circuitry routing each of the stimulus signals to the output devices in pre-determined correspondance with the number of pulse signals within a different one of the control signals.  The system of the present invention may be employed to sequentially stimulate several stimulation sites, with the stimulation sites being selected to combat the same or different body disfunctions.  Alternatively, the system of the present invention may be employed to repetitively stimulate the same stimulation sites while allowing an alteration in the stimu-lation sites to combat nerve fatigue or to provide a more effective electrode configuration, for example.

Abstract: PHONOGRAPH RECORD PLAYER                     ABSTRACT OF THE DISCLOSURE           In a phonograph record player, an improved control mechanism is provided for effecting lead-in movement of a tone arm from an elevated rest position outside the perimeter of a turntable to a selected set-down position on a record supported by the turntable so as to commence a play operation, and for effecting a return movement of the tone arm to its rest position upon the termination of the play operation.  In such control mechanism, a lever assembly is angularly displaced by a cam follower engaging in a cam groove of a control gear to effect the lead-in and return movements during turning of the control gear by engagement of a drive gear with first and second sets, respectively,of teeth on the control gear which are separated by first and second toothless gaps facing the drive gear in stop and play positions, respectively, of the control gear.  In order to initiate turning of the control gear from such stop and play positions, lead-in and return clutches are mounted at diametric-ally opposed locations on the control gear and are adapted to be selectively engaged by movement of a single actuating slide to its operative position in response to energizing of an electro-magnetic element with the control gear in its stop position or play position, respectively.  Thus, merely by controlling the single actuating slide, particularly through selective energizing of the electromagnetic element, lead-in, return or reject and repeat operations of the record player can be simply achieved.

Abstract: ABSTRACT OF THE DISCLOSURE      A coal mining apparatus and its method of use in which a continuous mining machine removes and transfers cut material reducing airborne respirable coal dust generated in the cutting and collection process.  The conventional high speed heat rota-ting with the bits going forward at the top is replaced by a triangular shaped dished out linear cutting head rotating with the bits mounted at the apexes going rearward at the top.  This produces a box cut in the mine face with a square cross-section.   After the head has made a box cut by sumping the full head dia-meter beginning at the mine floor, it is sheared upwardly pro-ducing a linear shear cut.  This shear step is at a constant depth equal to the complete cutting head diameter.  The modi-fied cutting head is used as part of the loading and transfer mechanism.  This is accomplished by reversing its direction of rotation and cutting on the upstroke from floor to roof so that the head acts as a bucket collecting the cut coal, then trans-ferred to an adjacent transport system which allows the cut coal to be loaded and conveyed away from the mine face without further dust generation due to free fall fracture on the floor or intermediate handling by a dust generating gathering head mechanism.  To insure that the coal is consistently discharged at the proper position, a movable bridge conveyor and follower assembly is used with the cutting head.
