Abstract: LATCH MECHANISM FOR VEHICLE SEAT        CONVERTIBLE TO BED                         Abstract A latch mechanism (24) disclosed secures a vehicle seat (10) in a seating position and is selec-tively releasable to permit movement of cushion, back, and auxiliary components (14. 16, 18) on a support linkage (20) to a bed position.  The latch mechanism includes a first latch (26) having a latched position for securing the cushion and back components (14, 16 in the seating position.  A second latch (28) of the mechanism has a latched position for securing the auxiliary component (18) in a vertical seating position at the rear of the back component.  A pair of the first latches are preferably provided at opposite lateral sides of the seat with the second latch therebetween and are releasable  in coordination therewith by an actuator (30) of the mechanism to permit unlatching that allows the seat movement to the bed position.  A laterally extending connector shaft (96) of the actuator coordinates the releasing of the latches and is pivotal-ly moved by a pedal-actuated member through a pair of cams.

Abstract: ABSTRACT OF THE DISCLOSURE           A multi-purpose power tool in which a power head and a power carriage are mounted for reciprocal translation on a pair of elongated tubular ways, the ways being pivotally mounted and counterbalanced with respect to a generally horizontal base or stand such that the power head and carriage may be moved indepen-dently in a horizontal plane or, alternatively, in a vertical plane.          The power head and carriage assemblies may be moved in a precise manner relative to the ways, either manually or by means of a variable speed motor drive.  Included within the power head is an arbor assembly which passes through a quill member, the arbor also being driven by a variable speed motor.  The quill assembly is provided with means for moving same outwardly from the power head to a desired extent and for subsequently locking it in that position.          The carriage assembly includes means for supporting and accurately positioning a work holding table.  By properly choosing the tool elements to be mounted on the arbor, the multi-purpose power tool can be made to function as a table saw, a disc sander, a vertical drill press, a lathe, a horizontal boring machine, a horizontal or vertical milling machine, a stationary adjustable router or a high speed shaper.

Abstract: ABSTRACT     A swing-force indicator for a playing piece of sports equipment, such as a golf club, racket, baseball bat or the like, comprising an elongate housing adapted to be attached to a portion of the playing piece.  A weight is movable on the housing between retracted and extended positions against spring action, becoming extended due to centrifugal force when the playing piece is swung, and being held in any extend-ed position by a releasable catch.  Normally the weight is held retracted by a yieldable biasing means which acts coun-ter to the centrifugal force.  An indicator shows the degree of extension of the weight, and gives a reading that is pro-portional to the force of the swing.  The advantage of the present construction over the devices of the prior art is that the operation is simpler and more straightforward, and that there are relatively few separate parts, whereby the overall manufacturing cost can be much lower.

Abstract: ABSTRACT      A demodulator is described for demodulating phase-encoded data signals transmitted on a noisy communication channel, such as, for example, radio communication chan-nels of a radio communication system.  The demodulator includes a digital phase-locked loop for phase-locking to the mid-bit transitions of the phase-encoded data signal, which, in the preferred embodiment is encoded according to the well known Manchester coding format, and further includes demodulating circuitry for sampling the phase-encoded data signal a predetermined number of times, weighting the samples according to predetermined weight-ing factors, totalizing the weighted samples for each bit interval and comparing the totalized samples to a prede-termined threshold value for ascertaining the logical state of each bit of the phase-encoded data signal.  For example, if the magnitude of the totalized samples is greater than or equal to the threshold value, a logical one state may be provided for the decoded data signal, and, if the magnitude of the totalized samples is less than the threshold value, a logical zero state may be provided for the decoded data signal.  In preferred embodiments of the present invention, the weighting factors assigned to each sample may be either binary weighted or sine weighted, although any suitable weight-ing factors may be utilized depending on the characteris-tics of the phase-encoded data signal.  The phase-encoded data signal demodulator embodying the present invention is particularly well adapted for demodulating high speed, phase-encoded data signals transmitted over radio channels to mobile and portable stations of a radio communication system.

Abstract: JEWELRY DISPLAY                 ABSTRACT OF THE DISCLOSURE       A jewelry display tray according to the present invention includes an upper structural member and a lower structural member.  A plurality of recesses are formed in both the upper and lower members.  The recesses in the upper member extend in a downward direction when the tray is in a substantially horizontal position, and are arranged in offsetting or staggered rows.  The recesses in the lower member extend in an upward direction and are similarly arranged in offsetting or staggered rows.  The upper and lower members are complimentarily assembled together so that the downwardly extending recesses of the upper member fit into spaces located between the upwardly extending recess of the lower member thus forming an interlocking structure.          Similarly, the upwardly extending recesses of the lower member fit into spaces located between the downwardly extending recesses of the upper member.  An upper surface element having access openings, overlies the recesses of the upper member.  Items of jewelry can thus pass through the openings in the upper surface element so as to be accommodated in the downwardly extending recesses of the upper member.  The upwardly extending recesses in the lower member permits receipt of exposed jewelry items accommodated in another tray thus permitting nesting of a plurality of jewelry display trays.  This arrangement permits spaced apart positioning of the items of jewelry for highlighting the appearance of each individual item.  The recess structure also provides means of protecting the jewelry items when stored.

Abstract: ABSTRACT OF THE DISCLOSURE         Control rods are inserted into the core of a nuclear reactor in operation to shut down the reactor output  Before completion of entire control rod insertion, a high-temperature coolant flowing in piping for reactor water clean-up system is sprayed into the space in the upper portion of the reactor vessel.  As said space is under negative pressure, oxygen existing in the water droplets of the sprayed coolant is separated. After completion of entire control rod insertion, a residual heat removal system is operated.  Said spraying operation is discontinued and a low-temperature coolant cooled by a heat exchanger in the residual heat removal system is sprayed into said space.
