Abstract: ABSTRACT     The cam switch mechanism which is particularly appropriate for use in a pullkey where one must be able to initiate two separate switching operations, i.e. lockout and signal, enables a pull on the wire (36) at either end of the unit to trigger a first response, e.g. lockout, but still permit further pulls on the wire to trigger repeated second responses, e.g. signal. First and second microswitches (one shown at 55a) are actuated via independent cam followers (one shown at 53) whose movement is controlled by linear sliding cams (27A, 27B) connected respectively to the pullwires (36) at opposite ends of the unit.   Each cam (27A, 27B) comprises two parallel cam plates with the four plates interleaved so that recessed zones (as at 15) in the plates control movement of the cam followers.   A manually controllable actuator, such as a lockout knob, may be provided to actuate the first microswitch (55a) independently of the movement of the linear cams without inhibiting subsequent sliding movement of the linear cams.   In the case of a latching pullkey the lockout knob has pins (82) projecting into holes (17a, 17b) in the linear cams so that relative movement of the cams (27A, 27B) automatically causes mechanical  latching of the lockout knob in a position in which it can only be reset manually.   Electrical lockout can occur before mechanical latching.   For a non-latching pullkey the pins (82) are omitted.

Abstract: IMPROVED FLUID FOIL SYSTEM     OLSEN, ERIC   Abstract of the Disclosure An improved fluid foil system which is particularly adapted yet not limited to use in sail craft.  When used in e.g. a sailboat, the foil is rotationally supported with respect to a mast and laterally tiltable about a longitudinal axis in either direction to receive the wind which in turn powers the boat on which the mast is supported.  The mast can be supported in the boat at the other end thereof so as to enable free rotation with respect thereto.  In addition, the system is provided with self-leveling means for the foil so as to continually urge such to its rest or non-tilted position, that is, in a position generally parallel to the water, i.e., at a zero attack angle with respect to the wind.  This combination of a self-leveling, tiltable, and freely rotationable foil enables the foil to be securely attached to the mast with a minimum of structural weight.          This in turn enables both simplified and improved control of the foil and the boat which it powers and otherwise enables maximazation of both light and heavy winds in a herethereto unachieved manner.

Abstract: L'invention concerne une méthode ainsi qu'un dispositif pour mesurer de façon quantitative l'intensité de la cavitation érosive apparaissant dans un liquide tel que, par exemple, l'eau douce.Selon cette méthode, on dispose dans le liquide un jeu d'électrodes de mesure comprenant une électrode de référence, au moins une électrode auxiliaire et au moins une électrode de travail faite en un métal choisi parmi ceux capables de former des films d'oxyde très isolants et devenant plus épais par mobilité ionique sous l'action d'un champ électrique, ce métal étant de préférence le titane. Les électrodes auxiliaire et de travail sont localisées dans la zone où l'on veut mesurer la cavitation et une tension anodique constante est imposée à l'électrode de travail à l'aide des électrodes auxiliaire et de référence. On mesure alors l'intensité du courant anodique et l'on détecte et mesure toute variation de cette intensité de courant. La variation ainsi mesurée est, en fonction d'un choix appropriée de la tension anodique constante imposée, directement proportionnelle à l'intensité de la cavitation érosive dans la zone de mesure. Cette méthode ainsi que son dispositif de mise en oeuvre peuvent être notamment utilisés pour le développement de machines hydrauliques dans des essais de modèles ou de prototypes, tels que des essais de pompes, turbines, hélices ou robinets, ainsi que pour la surveillance de machines en opération dans des centrales hydrauliques, thermiques ou nucléaires, ou des stations de pompage d'eau douce ou salée.

Abstract: A CAST BAR OF AN ALUMINUM ALLOY FOR WROUGHT PRODUCTS, HAVING IMPROVED MECHANICAL PROPERTIES AND WORKABILITY, AS WELL AS PROCESS FOR PRODUCING THE SAME ABSTRACT In AA standard 4000 series aluminum base alloys for wrought products, the large-sized products have been usually produced using large billets which had non-uniform cast structure, and the small-sized products have been usually produced by using extruded bars which had a disadvantageous directional property. The continuously cast bar of aluminum base alloys for wrought product according to the present invention: is of homogeneous structure; is free of defects; exhibits excellent mechanical properties, and; can be subjected, as cast or after a heat, treatment, to a working operation such as forging. A critical value of the secondary dendrite arm spacing (DAS) and a critical value of the size of second phase particles and/or the grain diameter, which critical values are substantially lower than those in the conventional aluminum alloy ingot, are responsible for fine cast structure capable of remarkably enhancing the workability and the mechanical properties of the aluminum base alloys having the following compositions. AA 4000 Al-Si-Mg series alloy: 4-12% Si; 0.6-1.3% Mg, and; balance Al. AA 4000 Al-Si-Cu-Mg series alloy: 2-12% Si; 1.5-5.0% Cu; 0.8-1.3% Mg, and balance Al.

Abstract: Abstract Power-Conserving Control System A control system, as for controlling automotive body functions, is powered by a limited capacity electrical  power  source  and  is  structured  and controlled in a manner to minimize consumption of electrical power.   The control system conducts data transactions between a central control station and one or more remote controllers connected therewith, and the central control station includes a provision for electronic signal processing for controlling the data transactions with the remote controllers.  A power FET is operatively connected to the power source and to a portion of the control system for selectively connecting or diconnecting power to that control system portion. The system employs a NMOS microprocessor.   The portion of the control system from which power may be disconnected will typically include the processor.  The level of system activity is monitored and a power-down, or "sleep" control signal is automatically provided if a predetermined condition of inactivity occurs.   That power-down control signa; is operatively applied to certain control circuitry for in turn causing the power switch  to  disconnect  power  when  the  power-down control results.  Correspondingly, a timer, which preferably is continuously powered, times a "sleep" interval during which power is disconnected from the relevant  control  system  portion  and  generates  a power-up  control   signal  at   the end of some predetermined time.   The control circuitry responds to this power-up control signal by causing the power switch to reapply power to the previously disconnected portions of the control system.
