Abstract: Drive member for timepiece movement comprising: a barrel comprising a drum mounted on an arbor; a main spring wound inside the barrel, and a core coaxial with and pivoting on the arbor; the exterior end of the spring being coupled to the drum and the interior end of the spring being coupled to the core; the exterior end of the spring is coupled to the drum by a first clamp that is pivot-mounted in the drum so that when the spring is unwound, the first clamp pivots in such a way as to hold the exterior turn of the first spring against the drum and when the spring is wound up, the first clamp pivots towards the center of the barrel to follow the exterior turn of the spring. The bending stresses in the spring are reduced.

Abstract: An ice cream filling apparatus for simultaneously filling multiple ice cream containers as they move along a predetermined path of travel extending between a receiving station and a discharge station and a method of operating the filling apparatus in a manner controlling the volumetric fill of each container as a function of the speed that the container moves along its predetermined path of travel. The filling apparatus includes a transport and filling mechanism which quickly and easily adapts to different size and shape containers and includes a series of cantilevered container supports. Each container support individually holds and positions an ice cream container beneath a filling nozzle in a manner facilitating clean operation of the filling apparatus and such that board caliper and bouncing of the container have an inconsequential effect on volumetric fill accuracy of the filling apparatus.

Abstract: An aerosol can containing a liquid propellant is placed on a can support platform (44). An operator actuated fluid control switch (84) provides pneumatic fluid or compressed air to a pneumatic cylinder (46) which continuously biases the aerosol can upward into engagement with a reservoir outlet (66) of a liquid reservoir (60). A sensing switch (52) senses movement of the can support, hence, the aerosol can. An operator actuated start valve (92) enables compressed air to be supplied cyclically (78a, 78b, 96) to a pump pneumatic cylinder (70). A pump (74) driven by the cylinder cycles a preselected number of times as counted by counter (90) to pump a preselected amount of liquid from the reservoir through the reservoir outlet and into the aerosol can.

Abstract: A portable apparatus for aerating liquids includes an aerating head, a mechanism for supplying gas to the aerating head from a cylinder when a control button is depressed, a platform for lifting a bottle containing liquid to be aerated into sealing engagement with the aerating head, and a rotary cam operable by a handle to raise and lower the platform. A pre-compressed coil compression spring is interposed between the platform and a button engaged with the cam to ensure adequate sealing pressure between the bottle and aerating head.
