Abstract: ABSTRACT OF THE DISCLOSURE            A solar energy collection system for a building is disclosed.  The system includes a solar energy collec-tor of modular form disposed at the exterior of the building and comprising an assemblange of individual collector units coupled together side-by-side.  Each unit includes a plurality of flexible plastic panels suspended in upright positions at the exterior of the building and the panels include a first panel which is adapted to absorb solar energy and which constitutes a solar energy absorbant body, said panel having front and rear surfaces from both of which solar energy absorbed by the body can be transmitted as sensible heat.  Second and third panels are spaced outwardly from the respective front and rear surfaces of the first panel and define therewith passageways in which air can absorb heat transmitted from the solar energy absorbant body.  These passageways communicate with an inlet and an outlet, the outlet being higher than the inlet so that heated air in the passageways tends to rise by convection towards the outlet.  A fourth panel is disposed at the inner side of the unit and is spaced from the third panel to form a passageway defining a return air flow conduit and communicating adjacent the lower end of the unit with the inlet of said heated air passageways.  Two end panels are dis-posed at respectively opposite ends of the unit generally transversely with respect to the first mentioned panels and are coupled thereto to define sealed ends for the passageways.  The unit also includes means defining a closed lower end of the unit and at least those panels in front of the solar energy absorbant body are transparent to sunlight.  The system also includes heating means in the building including a circulation circuit for heating fluid and heat exchange means coupled to the air passageway out-lets and to the return air flow conduits of the solar energy collector units and to the circulation circuit of the building heating means and arranged to permit heat transfer between the heated air and the heating fluid.

Abstract: ABSTRACT OF THE DISCLOSURE             An electromagnetic induction actuator for the trans-ducer arm of a magnetic disc file is described which provides faster operation without increase in input power as compared to present voice coil actuators.  The actuator consists of a trans-former having a fixed primary winding on a magnetic core.  An angularly movable coil is linked with the magnetic core forming a secondary winding of the transformer.  A permanent magnet generates a static magnetic field which is coupled to the coil.    One or more transducer arms capable of angular movement are attached to the coil. When a current pulse is applied to the primary winding, a current is induced in the coil which reacts with the static magnetic field to cause angular movement of the coil and attached arm.

Abstract: METHOD OF THERMALLY CRACKING HEAVY PETROLEUM OIL                   Abstract of the Disclosure The specification discloses a method of thermally cracking a heavy petroleum oil by introducing the heavy petroleum oil, heated in advance, into a reactor and contacting the heavy petroleum oil with a gas which does not react with the heavy petroleum oil at a temperature of 400 - 2000°C thereby thermally cracking the heavy petroleum oil therein, the method including using several reactors in succession so that the reaction can be carried out essentially continuously, and charging each reactor in advance with an amount of the heavy petroleum oil at a temperature lower than the reaction temperature.          In this way, excessive coking of the oil can be prevented and the reactors are subjected to less thermal shock, and therefore damage, when the main charge of heated oil is introduced.

Abstract: ABSTRACT OF THE DISCLOSURE          In an engine of the type having opposite side wall portions more or less differing from each other in rigidity, as in a so-called side valve engine, the axis of the piston unit is set at such an angle of inclination relative to the axis of the asso-ciated cylinder bore that the two axes substantially coincide with each other in the power or explosion stroke of the engine cycle when the cylinder block is tilted, under the tensile load acting on the engine structure, on account of the differ-ential rigidity of the opposite side walls thereof.  With this axis arrangement, any uneven wear of the mating bearing surfaces of the piston and cylinder and of the crankpin and bore in the large end of the associated connected rod is effectively pre-vented.

Abstract: CONTROL SYSTEM FOR PHASE DISPLACEMENT REGULATOR CIRCUITS                 ABSTRACT OF THE DISCLOSURE          A control circuit for a regulator circuit of the type in which the regulator output voltage and current are dependent upon the phase angle between an unregulated a-c input voltage wave and a regulating or control voltage wave.  The control circuit generates a reference signal that is locked in phase with the a-c input voltage wave and a control signal that is locked in phase with the control voltage wave.  Output voltage sensing circuitry is arranged to increase or decrease the phase angle between the control signal and the reference signal, as required, to maintain the output voltage of the regulator at the desired, regulated value.  A phase difference limiting network allows the control signal to vary freely in phase with respect to the reference signal so long as the control signal remains within an angular window of from 0° to 60° of lag behind the reference signal and assures that limits of this angular window cannot be exceeded.  A damping signal is utilized to assure that the rate of change of the phase angle between the control and reference signal is limited in a manner which affords both high control system stability and rapid dynamic response to changes in input voltage and output current.  OR-ing circuitry is also provided to allow the output current to reduce the regulator output voltage and thereby limit the regulator output current to a safe value when the output current attempts to rise beyond its highest rated value.

Abstract: ABSTRACT OF THE DISCLOSURE A play gym comprising a horizontal bar from which a glide swing and other rides are suspended is supported at its opposite ends by pairs of legs.  Special three-axis pivot joints connecting the pairs of legs to the horizontal bar permit each pair of legs to be folded together and against the horizontal bar so that the gym can assume a stick-like configuration. When the legs are unfolded to support the horizontal bar, clam shells form-ing parts of the pivot joints clamp around the ends of the horizontal bar thereby preventing end-wise movement and racking of the play gym.  Provision is also made for substituting one pair of legs by a horizontal pivot ar-rangement which can be secured to a vertical support so that the gym can be used in a small area and be folded up out of the way against the support when not in use.  The glide swing is foldable so that it can be stored in a minimum amount of space when not in use.  The swing includes a set of de-pending hangers, a platform pivotally secured to the lower end of the hang-ers, and a pair of oppositely-disposed seat assemblies pivotally connected to the hangers.  A bar releasably maintains each pair of legs in a spread-apart condition.

Abstract: An automatic clock phase adjustment circuit is incorporated in a local unit of a data clocking system.  The local unit also includes a clock pulse generator and a local data storage device.  The system also includes a remote unit having a remote data storage device.  The automatic clock phase adjustment circuit receives clock pulses from the generator and produces output clock pulses having first and second half periods interconnected by a clocking transition which when applied to the remote storage device causes clocking out of data to the local storage device.  The circuit also produces a sampling pulse during each of the first and second half periods of the output clock pulses and is operable to detect in which particular one of the half periods a positive transition in the incoming data has occurred during the interval of a sampling pulse in that half period.  This permits the circuit to produce local or input clock pulses for clocking in the incoming data at the local storage device during the other of the half periods so that the clocking edges of the input clock pulses will not coincide with any of the positive transitions of the incoming data when applied to the local storage device.  As a result, reliable storage of the incoming data is guaranteed to occur at the local storage device at times when the data is stable.
