152 of the corresponding link 151, with diaphragm fifty eight pressed tightly (by seal plate 155) between ends 152 and 156b (to stop liquid leakage into the control box meeting). With reference again to FIG. 7, cam tracks 50a have equivalent shapes, but the two cams 50 are assembled essentially "again-to-back" (one is rotated by 180 degrees about the vertical axis in FIG. 7 relative to the other), which orients the cam track 50a of considered one of them because the mirror picture of cam track 50a of the other (in order that the angular orientation of 1 track 50a about shaft 52 is displaced relative to the orientation of the opposite track 50a about shaft 52). Similarly, Dashboard in the FIG. 10A embodiment, two equivalent cams 50' are assembled basically "back-to-again" on shaft 52, thus orienting cam observe 50b of considered one of them as the mirror picture of cam monitor 50b of the other. As proven in FIGS. A seal plate 155 (shown in FIGS. 155a (proven in FIG. 7) of control box portion 14a. A shift hyperlink 156 fits inside an opening through the middle of each seal plate 155. As cam 50 pivots link 151 upward (or downward), hyperlink 156 at the alternative finish of the inflexible shift assembly (comprising hyperlink 151, tube 154, and hyperlink 156) will pivot downward (or upward).
Alternatively, the components are all connected to a single circuit board sixty eight (during which case, board 70 is omitted). In a most popular embodiment, the microprocessor is preprogrammed to assert any of two or extra units of management indicators to motor 74. For example, the microprocessor can be programmed to assert a first set of relatively low present alerts to the motor within the event that the batteries powering the apparatus have a low level (or if the onboard sensors point out that the apparatus is stuck towards an obstacle), and otherwise to assert a second set of comparatively excessive present indicators to the motor. Stepper motor 74 and cam gear cluster fifty five are also mounted inside assembled parts 14a, 14b, and 14c. Two cams 50 and one cam gear fifty four are fixedly mounted on cam shaft 52. Shaft 52 is rotatably mounted to aspect 14a by cam bearings 51. Thus, cams 50, gear 54, and shaft 52 rotate together as a unit. Gear cluster 55, engaged between motor seventy four and cam gear 54, is pushed by motor 74 (which is ideally an electronically controlled electric step motor).
The inventors contemplate that the invention can also be helpful for other applications, e.g., to clean other surfaces submerged in water or in liquids aside from water. 4 and 13) and an outlet 10. Outlet 10 is dimensioned for attachment to the lower finish of a flexible hose eight (shown solely in FIG. 13), and so outlet 10 is generally referred to herein as a "hose connection" 10. Typically, the higher end of hose 8 will likely be connected to one of the pool's current suction ports, which in flip is connected to a standard surface unit 8A (proven in FIG. 13) disposed Above ground pool installation Texas the water surface. A first embodiment of the invention shall be described with reference to FIGS. 1-eight and 11-22. On this embodiment, the invention includes a turbine assembly 12 having an inlet 9 (shown in FIGS. The time period "water" can be utilized in a broad sense all through the specification, together with in the claims, to indicate recent water, salt water, and another liquid through which a floor (to be cleaned by the inventive apparatus) is immersed.
In any embodiment of the invention, the programming card could be coded with a sample of notches at along its edges. Use of such a battery pack allows safer and more convenient operation than might be achieved with Houston pool cleaning services cleaners which have employed a power cable extending to the submerged apparatus from a energy supply disposed above the water surface. Selection of a larger inlet measurement ends in slower, more thorough, cleaning than is generally achievable with a smaller turbine inlet. When the notched card is placed into place adjoining the magnetic (or Search Home optical or mechanical) switches, the card will (or is not going to) actuate mechanical means for controlling the scale of a turbine assembly fluid inlet nozzle relying on the absence (or presence) of a notch at the placement of the mechanical means. The larger inlet will also permit for passage of bigger debris. In preferred embodiments, the inventive apparatus is powered by an onboard battery pack sealed in a water-tight enclosure. The smaller inlet will give larger turbine speed resulting in larger unit velocity and likewise increase torque for better wall climbing.
The currents of the "relatively low" current indicators may be selected to maximise the torque exerted by the motor while minimizing battery consumption, and the currents of the "relatively high" current alerts will be selected to maximize the torque exerted by the motor (with no battery consumption minimization constraint). Each of cams 50 defines a cam observe 50a (greatest shown in FIG. 5) having a non-uniform radius relative to shaft 52. In variations on this embodiment, cams 50 are changed by cams 50' shown in FIG. 10A or cams such because the cam having camtrack 50A' shown in FIGS. Thus, the motor could be controlled to devour much less energy in response to the "comparatively low" current alerts than in response to the "relatively excessive" current indicators. 9 and 10. Each of cams 50' defines at the least one cam monitor 50b having a non-uniform radius relative to central portion 52a of cam 50' (cams 50' are mounted to shaft fifty two by inserting shaft fifty two by portion 52a of every cam 50'). A pair of cam follower hyperlinks 151 (one of which is shown in FIG. 7A and in FIG. 7B) are supplied, each having a cam follower shaft one hundred fifty which rides in one of many cam tracks 50a or 50b. Or, a pair of cam follower hyperlinks 151' (one shown in each of FIGS.

For example, the microprocessor can be programmed to assert a first set of relatively low present alerts to the motor within the event that the batteries powering the apparatus have a low level (or if the onboard sensors point out that the apparatus is stuck towards an obstacle), and otherwise to assert a second set of comparatively excessive present indicators to the motor.
