Abstract: A device comprising a display unit which is configured to display, on a screen of the cockpit of the aircraft, a pitch bar illustrating a pitch order and means for adapting the direct gain of the pitch law used to the effective manual behavior of the pilot in order to obtain a homogeneous response from the aircraft.

Abstract: A Biorythms analog computer-calendar is provided to display without computations the level of the physical, the emotional, and the intellectual biorythms of a human body. The level of the three biorythms appears on display in analog and digital forms for any dialed calendar date, if the computer-calendar is set initially with the individual's birth date. The analog elements used to register the three biorythm levels are drums attached to gears with a number of teeth equal or proportional to 23, 28 and 33, or to the period of the three biorythms respectively. A calendar arrangement is introduced to create a correlation between the displayed biorythm levels and the calendar date associated with them.

Abstract: Flat indicia wheels are used in conjunction with a Geneva-type register movement. The register utilizes transfer wheels which have an outer edge shaped to contain a plurality of scallops and cusps. Each transfer wheel is associated with a transfer disc that rotates about an adjacent shaft and whose transfer arm causes the transfer wheel to rotate a preselected angular distance by striking a peg attached to the transfer wheel. This type of movement makes possible the use of flat indicia wheels with indicia, or numerals, imposed on a flat surface of the wheel. The presentation of a flat numeral through an opening in a faceplate provides for easier reading and, when used with an automatic reading device such as a light pin, reduces the chances of an erroneous reading.

Abstract: A lap counter for free running radio controlled toy vehicles includes two edge members which together define a convergent section of track and one or more counting devices on one or both sides of the convergent section of track. Each counting device includes two or more counting stations each of which has an actuating member associated with it positioned to be contacted by a trigger member carried by a vehicle. The actuating members of each counting device are arranged at different heights and connected to a respective one or two indicator arms which indicate the number of laps driven by a vehicle.

Abstract: A plurality of presettable digit wheels are rotatably mounted on a first axis. Each of said wheels is rotatable to a plurality of preset positions corresponding to respective values of an associated digit position of a preselected count. Retaining means retain said presettable wheels in said preset positions during a counting operation of the counter. A signal generator comprises axially movable cam follower means arranged to generate a signal when said counter has counted to said preselected count. A plurality of presetting members are associated with respective ones of said presettable wheels and pivoted to a stationary first pivot. At portions remote from said first pivot, said presetting members are engaged by a guide member, which is pivotally movable between first and second positions to move said presetting members about said pivot out of and into engagement with said presettable wheels. First spring means are adapted to urge said guide member to said first position.

Abstract: A mechanical calculator employs a register consisting of gears. Each register gear has two sets of teeth. One set has teeth all around the circumference of the wheel while the other set consists of a single carry-over tooth. The register gears are spaced widely enough apart that they do not engage one another. An intermittent carry-over motion is transmitted from one register gear to an adjacent register gear by a selectively insertable and removable carry-over gear, which is mechanically unconnected to the remainder of the calculator. The operations of multiplication and division are enabled by a set of individually selectively insertable and removable multiplying gears. The number of teeth on these gears, and their diameters, are integral multiples of those on the register gears. The multiplying gears are mechanically unconnected to the remainder of the calculator.
