The invention concerns a watch with a mechanical movement of the type comprising at least two regulating systems (SR1, SR2) each including a mechanical oscillator and an escapement. The movement includes as many sub-assemblies (SE1, SE2) as there are regulating systems, each of said sub-assemblies including a regulating system (SR1, SR2), a barrel (B1, B2) and a going train transmitting energy from the barrel to the regulating system inside the sub-assembly. A differential display gear (Da) connects the barrel or the going train of each sub-assembly to the display (A) to average out the rate of the two sub-assemblies. In a preferred embodiment, the two sub-assemblies are mounted on a common rotating support (5) and their regulating systems are tourbillons which make an orbital movement about the centre of the watch dial.

An efficient flying device having flapping wings, an ornithopter, which uses many of the principles seen in bird flight, is presented herein. The wings are highly flexible, translationally stable and oscillate as a natural pendulum. Described as a springboard, the wings have a singular natural frequency, and a pumping means drives the wings at that frequency. Feedback means are described by which to accomplish this, whereby deflection of the wing affects an escapement mechanism which controls the timing and direction of the pumping means. Wing design is described whereby camber, flexure, torsion and directionality of wing components affect efficient propulsion, lift and differential reactivity with air during downstrokes and upstrokes. A crook element in the wing spar at a location proximal to the body of the device redirects vertical oscillation to horizontal. Other features are addressed, such as rearward vortex production and reaction, a double aerofoil wing construction, lateral and vertical wing curvature, rearward wing and featherlike element flexure to produce thrust, and connection of separate elastic elements to reduce power requirements.

A mechanism to retrofit modern motorcycles with a foot operated clutch or to be installed as original equipment is disclosed. The mechanism has an escapement mechanism, such as a pawl and ratchet, for holding the clutch in disengaged condition when a rider applies positive pressure on a foot pedal without requiring the rider to hold the foot pedal down with his or her left foot. This frees the rider to balance the motorcycle. The mechanism then allows the clutch to be readily reengaged when the rider desires to move the motorcycle by applying further positive pressure to the foot pedal.

Each air bag may have a plurality of cushioning air bags enclosure layers mounted to a thin foamed polymer shell lining. Each enclosure layer of each air bag has an interior filled with a resilient multi-cellular sponge like material, such as a shaped foamed polyurethane sponge, and has a plurality of air escapement openings sized to meter the release of air under impact to the helmet hard shell under predetermined pressure with a different air release pressure for each enclosure layer.

A power assembly for dispensing product from a container includes a pump mechanism and an energy storage mechanism. The pump mechanism includes a rotatable actuating collar connected through an escapement mechanism with a drive screw with an externally threaded shaft engaged with internal threads in a piston. Rotation of the collar reciprocates the piston to store energy in the energy storage mechanism and to draw product into a pump chamber from which the product is dispensed. An actuator is connected with a stem valve to open it when the actuator is depressed, enabling the energy storage mechanism to push the piston back to its at-rest position to force product from the pump chamber and ready it for another dispensing cycle. Disengagement of the escapement mechanism when the actuator is depressed prevents rotation of the actuating collar. Different energy storage mechanisms can be interchangeably attached to the pump mechanism.

The invention is a method and apparatus for extracting power from a buoyant source within a contained column of liquid. It is comprised of an endless chain of movable buoyant objects, a means to convert the movement of the chain into useful work and a tank filled with a constant volume column of water. The buoyant objects comprising the chain sequentially enter the bottom of the water column, move up through the column and emerge at the surface. The emerging buoyant objects leave the tank and are directed to the tank bottom were each buoyant object repeats the cycle. As the chain of buoyant objects cycle through the water column, the volume of water remains constant, with one buoyant object of the chain entering the bottom of the water column as one is exiting at the top surface. The movement of the chain is a function of the buoyancy of the buoyant objects and the movement is converted to work by any conventional means using a rotary drive or linear escapement motor.

The movement (1) of the watch includes a constant force device (14) inserted in a going rain connecting a spring barrel (2) to an escapement having an escapement wheel and including a third wheel which completes one revolution in several minutes. The input element of the constant force device (14) is the third wheel (12), the output element of said device (14) being a second third wheel (20) connected via gearing to the seconds pinion (38). The second third wheel is secured to a star wheel (26) that only releases the train upstream of the constant force device once per minute, thus forming an independent minutes display because the minute hand (7) jumps forward at each minute. This arrangement minimises the transmission of shocks between the constant force device and the escapement and can advantageously be combined with a tourbillon (40).

A screw feeder adapted for rapid changeover of the type of screws to be fed. The feeder has a collator section having a floor with slots to collate random screws into rows and an enclosure about the floor for retaining random screws on the floor. The collated screws are fed along the slots into slots in a dispensing section of the feeder where they are then moved in queues to an escapement to be picked off one by one for deposit into a receiver. The collator section floor is oscillated about an axis between a position where the floor slopes downward from a downstream end in the slot direction from an upstream end in the opposed slot direction to a position where the floor slots slope upward to the upstream end. The collator section enclosure has a gate closure at the upstream end of the floor and the slots on the floor extend completely to the upstream end so that, with the gate open and the collator section oscillated to tilt the slots downward toward the upstream end, the screws in the slots will slide to the upstream end and out of the feeder to empty it. A chute is provided below the upstream end to collect the screws falling from the feeder. The screw feeder may have a collator section that collates and feeds screws along slots to the slots of a separate dispenser section for dispensing. For emptying the feeder for screw changeover, the dispensing section is raised so that the screws slide back to the collator section held at the lower position for screw removal. A flow regulator gate adjacent the dispenser section is openable on rotation downward of the collator section to clear screw jambs. The regulator gate also opens when the dispensing section is raised to clear the screws back to collator section for changeover. Detents are provided in the collator section slots at an intermediate location therealong to maintain the collated screws closer to dispensing section for ease of transfer thereto. The detents are selectively removable so that they will not interfere with emptying the feeder on changeover to new screws.
