Abstract: ABSTRACT OF THE DISCLOSURE      An apparatus for reproducing video signals recorded in successive parallel tracks extending obliquely across a magnetic tape by means of at least one rotary magnetic head which scans the tracks in succession at a rate dependent on the speed at which the tape is moved longitudinally by a tape transport assembly, is provided with a track searching arrangement which includes a manually rotatable wheel and a control circuit for regulating the speed and direction of movement of the tape by the tape transport assembly in dependence on the speed and direction of rotation of the manually rotatable wheel.  In response to relatively slow-speed rotation of the wheel within a first speed range, the speed of movement or transport of the tape is varied continuously in proportion to speed of rotation of the wheel.  For rotation of the wheel at speeds within successively increased speed ranges, the tape is moved or transported, preferably only by driving of the supply and take-up reels therefor, at successively increased, substantially constant respective speeds having successively increases ratios to the corresponding speeds of rotation of the wheel.

Abstract: HELICAL BROACHING TOOL FOR CURVED SURFACES            Abstract of the Disclosure A broaching tool is described having an elongated tool body with an arcuate face of preferably half-round configuration.  A plurality of recesses are formed on the arcuate face, each having a flat bottom face inclined in-wardly and rearwardly within 1 - 15° of coincidence with the longitudinal axis of the body and an arcuate abutment wall perpendicular to and rearwardly surrounding the flat bottom face.  These recesses are arranged in   helical paths of increasing diameter in a rearward direction to form a series of spaced helical rows.  Each recess contains a rotatably indexable cylindrical cutter disc.  This con-figuration of broach has the advantages of providing excellent chip clearance between the cutter  and also providing a uniform load on the tool during broaching.

Abstract: STATUS REPORTING               Abstract of the Disclosure In a plural unit system, particularly of the data processing type, controlled units such as tape drives, constitute status reporting units (SRUs) which report status including error conditions to one or more status analyzing units such as computers (CPUs), programmable controllers, and the like.  Each of the SRUs has a register, such as a shift register, associated therewith for receiving error status indications.  The signal state of the shift register when all zeros indicates error-free status, any nonzero state signifies an error.  An OR circuit receives signals from all of the bit positions of each of the respective shift registers and combines same into an SRU group error indicating signal. A second register, also a shift register, associated with the respective SRUs receives the output of the OR circuit in one of its bit positions, the bit position indicating the address of the reporting SRU.  The output of the two shift registers associated with each of the SRUs are serialized onto one wire and supplied to an intermediate shift register.  Combined signal status in the intermediate shift register are then supplied to one or more status analyzing units in a two byte format, i.e., one byte for the address and a second byte for the error status.  An appropriate status analyzing unit then determines the error condition of the SRU.  If more than one SRU is in error, then the address byte will have more than one binary one indicating state requiring further analysis by the respective status analyzing units.

Abstract: ABSTRACT OF THE DISCLOSURE    An oscillating pedal bicycle in which the downward force exerted by a rider is converted from the osciilating-motion of the pedals into a unidirectional rotation of the drive wheel.  The oscillating motion of the pedals is trans-mitted by flexible tension members to a conversion mechanism for converting the linear motion of such tension members into the rotary motion of the drive wheel.  Maximum utilization of the motive power of the rider is achieved through the use of a quick-release, variable position body restraint and a variable height seat, both of which are adjustable while the bicycle is in motion, while maximum transfer and conversion of such motive power is achieved by an improved pedal return and tension member rewind mechanism and an improved drive mechanism.  Pedal stabil-lizers, rotatable foot restraints and foot actuated lever control mechanisms are provided to maximize motive power and efficiency.

Abstract: ABSTRACT      In foldable boats, it is known to have transverse ribs for bracing the boat assembly and removable seats attached to the side panels.  In this invention the means for bracing the hull serve as foldable seats, each having an upper horizontal member, hinged at its front and back edges to two vertical support members, which in order to contact lengthwise the side panels, have their outlet edges downwardly and inwar-dly inclined at approximately the angle of these panels.          Each vertical support member of a seat is provided by a shape of a W, which allows the water acting from out-side the hull to bend the bottom panels inwardly and upwardly.  The boat comprises also at least one trans-verse beam serving to brace supplementarily the hull in its open position and also to keep together all the panels, when the boat is folded.

Abstract: SAFETY BRACE                     ABSTRACT OF THE DISCLOSURE            Provided is a brace for preventing a truck body from falling when raised above its chassis for maintenance, inspection or servicing.  The brace includes a support column one end of which is pivotally connected to a body longsill and the other end is retained by a release mechanism located on the body for holding the column in riding position.  Provided on the chassis is a retaining means for securely retaining the column when it extends between the body (when raised) and chassis as a brace to prevent the body from falling.  A stop means is provided for limiting the pivot angle of the column.  The brace is installed in supporting position without an operator having to locate any portion of his body under the truck body while raised.  This is accomplished by actuating the release mechanism to release the column.  The body is then raised from remote control location and the column pivots until it abuts its stop mechanism which locates the lower end of the column above the retaining means on the chassis.  Lowering of the body then joins the column and retaining means to form a brace structure which prevents the body from being further lowered.

Abstract: ABSTRACT OF THE DISCLOSURE       In a method of drying boards by radio-frequency heating a stack of boards is passed between live and earthed electrodes.  The connections to the electrodes are periodically reversed so that each is alternately live and earthed; this increases the uniformity of heating in the stack.  Preferably the boards are stacked in short spacer sticks to delay the escape of steam from intermediate boards in the stack and reduce surface checking.  The escape of steam from the top and bottom boards of the stack to be dried can be delayed by using top and bottom covering boards treated with a liquid substantially unaffected by radio-frequency heating.

Abstract: Abstract An acoustic current meter in which two channels have acoustic¦ paths oriented at right angles to each other to measure orthogo-nal components of n current velocity.  Each channel includes two transducers aimed at an acoustic mirror so that the reflected acoustic signal from each transducer impinges upon the opposite transducer.  Periodically, a burst of high frequency acoustic energy is simultaneous emitted by each transducer.  A current flowing produces a relative phase shift between the received signals representative of the current velocity.  The output signal produced by each of the transducers is mixed with a common reference signal to provide two, low frequency, beat frequency signals having a phase difference proportional to the current velocity.  Due to the reduction in frequency, the phase shift is expanded in time with respect to the phase shift of the acoustic signals and may be easily measured.
