Abstract: ABSTRACT OF THE DISCLOSURE:         Water sporting boat of the pedal type comprising a surfboard having a hollow keel at the stern into which is provided a mechanical transmission connected to one end of a rotary shaft, a propeller being mounted at the other end of the shaft, outside the hollow keel.  Pedal power is transferred to the mechanical transmission by a chain drive also connected to a pedalling rack fixed on the surface of the surfboard.  A steering rack, provided forwardly of the pedalling rack, is connected to a rudder, at the stern of the surfboard, by a cable transmission. The steering rack includes a handle bar and the cable transmission is connected to the rudder so that the latter responds to the same steering direction as that applied by the handle bar.

Title: Continuous process for producing granular calcium hypochlorite particles

Abstract: A CONTINUOUS PROCESS FOR PRODUCING     GRANULAR CALCIUM HYPOCHLORITE PARTICLES            Abstract of the Disclosure A continuous process for producing granular calcium hypochlorite particles comprises admixing lime and an aqueous liquid in a mixing zone to form a lime slurry.  The lime slurry is fed into a crystallizing zone along with a calcium hypochlorite-containing liquid to produce a slurry of coarse dibasic calcium hypo-chlorite crystals and to elutriate a fines slurry from the crystallizing zone.  The coarse dibasic calcium hypochlorite crystals are separated from a dibasic hypochlorite mother liquor and fed to a chlorinating zone.  Reaction of the coarse dibasic calcium hypo-chlorite crystals with a chlorinating agent is conducted to produce a slurry of hemibasic calcium hypochlorite crystals.  The slurry is fed to a separator to separate a hemibasic hypochlorite mother liquor from the hemi-basic calcium hypochlorite crystals.  Hemibasic calcium hypochlorite crystals are chlorinated in the presence of an alkali metal hydroxide to produce an aqueous paste of calcium hypochlorite dihydrate which is sprayed into a heated zone to evaporate water and produce granular calcium hypochlorite particles.         The novel process of the present invention can employ low grade limes where fine particles including dibasic crystals, insoluble impurities and unreacted lime are removed as a slurry from the crystallizing zone.  This slurry is chlorinated to produce a calcium hypochlorite-containing liquid which is returned to the dibasic crystallizing zone.  Large crystals of highly pure dibasic calcium hypochlorite are produced as an intermediate product.  These dibasic crystals are chlorinated to produce hemibasic calcium hypochlorite crystals as a further intermediate product.          Chlorination of the hemibasic crystals yields a slurry -ii-of sufficiently high Ca(OCl)2 assay to meet the specifications for a marketable product.  This process eliminates the filtration of calcium hypochlorite dihydrate slurries required in previous commercial processes as well as the need to remove solid sodium chloride.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved flow distribution system for a cata-lytic reactor plenum chamber for a gas-liquid-solids ebullated bed reactor.  The flow distribution system includes a downwardly directed conduit and a flow distri-butor device such as a baffled nozzle attached to the inner end of the conduit, said nozzle containing at least two substantially parallel baffle plates usually oriented substantially normal to the nozzle inlet flow direction for providing initially downward flow and good mixing and radial flow dispersion of gas-liquid materials in the lower portion of the plenum.  The initially downward flow is then deflected generally upwardly by the curved lower head of the reactor plenum chamber and passes uniformly upwardly through a flow distribution grid into the ebullated catalyst bed.  A sparger can be provided in the plenum above the flow distributor device for feeding additional gas-liquid mixture into the reactor. Alternatively, the flow distribution system can include a oonical-shaped flow deflector device having its base rigidly attached to the plenum lower wall and having its apex oriented toward and substantially aligned with the centerline of the inner end of the conduit.  The flow distribution system provides substantially uniform flow dispersion of the gas-liquid mixture into the ebullated bed, and minimizes stagnant zones in the plenum and thereby provides fouling-free operation of the reactor.

Abstract: Abstract of the Disclosure An apparatus for measuring a flow of intake air to an engine includes a bridge circuit including a heat resistor placed in an intake air path of the engine, a resistor for sensing the temperature of the intake air, and a plurality of balance resistors.          A heating current is supplied to this bridge circuit through a transistor controlled by a periodical current-passage control signal generated by a microcomputer.        A signal Vh, representing a temperature change of the heat resistor heated by the heating current, is detected by the microcomputer.  A first correction value is computed by using a difference between the detected value from the microcomputer and a signal Vho, representing temperature of the heat resistor when the bridge circuit is balanced at normal tem-perature.  A time width correction value .DELTA.Dol is computed from a table on the basis of the first correction value.  The correction signal .DELTA.Dol is used for correcting the current passage time.  The current passage time width as corrected is used for computing a flow of the intake air.
