  • Patent number: 8794823
    Abstract: A magnetic resonator, for a timepiece, is disclosed which comprises an oscillator of the tuning-fork type having first and second branches in the form of a U of which at least a first branch supports a first permanent magnet defining a first magnetic field, an escape wheel, designed to be arranged in engagement with a watchwork gear train in order to allow it to be driven by a power source of the timepiece and, situated within range of said first permanent magnet in order to undergo the influence of the first magnetic field. In particular, provision is made for the escape wheel to be free and support at least two permanent magnets, preferably at least four, arranged so that the vibrations of the first branch of the tuning fork, on the one hand, control the rotation speed of the escape wheel and, on the other hand, are sustained periodically by the magnetic interaction between the first permanent magnet of the tuning fork and the permanent magnets of the escape wheel in order to define a free escapement.

  • Publication number: 20130194900
    Abstract: A mechanism for advancing, by periodic jumps, a pivoting cage for an escapement mechanism, including: a retaining mechanism authorizing or preventing the pivoting of the cage, depending on its movement; and a stopping mechanism authorizing or preventing the pivoting of the retaining mechanism, depending on its angular position. A constant force device causes periodic cooperation of the retaining mechanism, which includes a flirt arranged to perform complete revolutions and is connected to an input thereof, with the stopping mechanism, which includes a star wheel and is connected to an output thereof, whose trajectories interfere with each other, to pivot the cage when the stopping mechanism allows the pivoting of the retaining mechanism and to stop the cage when the stopping mechanism locks the retaining mechanism.

  • Publication number: 20090165430
    Abstract: A reusable parcel harness for securing a parcel to a dog's chest generally includes at least one pin bar having first and second mounting pins extending therefrom towards a latch housing, a spring-loaded latch to releasably secure the pin bar to the latch housing or pin bar in a closed configuration, a latch release mechanism, and a harness attached to the latch housing to secure the apparatus on a dog. The spring-loaded latch biases the pin bar and the latch housing towards an open configuration. A latch release processor actuates the latch release mechanism upon receipt of a locally or remotely generated latch release signal. A parcel to be secured to the harness includes a parcel body and straps extending from opposing sides of the parcel body. Each strap terminates in a mounting loop that can be secured about a mounting pin on the harness.

  • Publication number: 20090115204
    Abstract: A self latching latch mechanism is disclosed which includes a latch mounted to a first wing and a strike mounted to a second wing or a fixed member. The latch has a latch tongue which can move between a latching position in which the latch tongue can engage the strike to secure the first wing relative to the second wing or fixed member, and a free position which allows relative movement between the first wing and the second wing or fixed member. Latch tongue biasing means are provided to bias the latch tongue towards the latching position. Operating means are also provided to move the latch tongue from the latching position to the free position, and there is a hold back member which can move between a first position in which the latch tongue is prevented from moving to the latching position, and a second position in which the latch tongue can move to the latching position. The hold back member is biased to the first position.

  • Publication number: 20080121053
    Abstract: A latch release for allowing two latched members to be unlatched from each other. The latch release includes a bubble body comprised of an elastic material. The bubble body is adapted to deform such that depressing of a first section of the bubble body in a first direction deforms a second section of the bubble body to push the latched members apart.

  • Patent number: 6802394
    Abstract: A self-contained automatic lubricator for automatically dispensing fluent lubricant over a period of time is provided. The lubricator comprises a cylinder having a front wall with a discharge outlet, a rear wall and cylindrical side walls. A piston is movable within the cylinder from a rear position to a forward position. The piston and the side and front walls of the cylinder define a variable volume chamber for containing the lubricant to be dispensed, and a spring for moving the piston from its rear position towards it front position to reduce the volume of the variable volume chamber over a period of time for expelling lubricant through the discharge outlet. The lubricator further comprises a controller including gearing and an escapement mechanism, for controlling the transfer of energy from the spring to the piston and an electrical element controlling operation of the escapement mechanism (12).

  • Patent number: 6708576
    Abstract: The escapement includes first (3) and second (4) escapement wheels meshing with each other, one of these wheels being driven by the gear train. It further includes a lever (5) capable of receiving the impulses generated alternately by the first and second wheels and to transmit these impulses to a plate (2) which carries a sprung-balance. The lever is arranged to lock alternately the first and second wheels after each impulse transmitted.

  • Patent number: 6360848
    Abstract: A vertical reciprocating conveyor having a safety mechanism for automatically locking the carriage of the conveyor at an elevated level upon uncontrolled vertical movement of the carriage. The conveyor includes a safety mechanism having a locking device mounted onto the movable carriage. The locking device includes a safety cam that is movable between an engaging position and a non-engaging position, such that when the safety cam is in the engaging position, the safety cam prevents the carriage from moving along the vertical support columns. The safety mechanism further includes a speed-sensing device that detects the speed of vertical movement of the carriage. When the speed of the conveyor exceeds an upper speed limit, the speed-sensing device releases the locking device. The speed-sensing device includes a cylindrical housing having a weighted shaft that slides into and out of the housing.
