Abstract: A bowl, which accommodates a coating, is removably mounted in a casing. A moving device in the casing is coupled to the bowl for rotating said bowl. A heater is positioned in the casing in operative proximity with the bowl for melting the chocolate. A cooling unit is positioned in the casing in operative proximity with the bowl for cooling the coating. A control circuit is electrically connected to the heater and cooling unit for controlling the heating and cooling of the coating.

Abstract: An improved resilient retainer which provides a highly reliable clamping action upon grooved clevis pins and the like. The pinless retainer configuration comprises two essential sections; a clamping section which is spring loaded to be secured around the core diameter of a grooved clevis pin together with an entry section which prevents the retainer from being removed easily. The retainer requires a grooved clevis pin and the like to be inserted past a first entry section and then snapped into the clamping section. The retainer may be formed from any resilient material and operates effectively with a minimum of insertion force without sacrifice of positive clamping effectiveness. In a second form the pinless retainer includes an encompassing guard clip for the entry section with removal from a grooved pin requiring a first removal of the associated guard clip.

Abstract: An extremely fast-acting valve operator including a piston slidable in a pneumatic cylinder and connected by means of a chain and sprocket with the rotatable actuating shaft of a valve so that rapid movement of the piston imparts a rapid rotation to the shaft to open the valve. The piston is subjected to a high pressure gas but is initially restrained against motion within its cylinder by means of a quick release mechanism whereby release of said mechanism results in the piston undergoing immediate and rapid movement responsive to the expanding gas to thereby rapidly open the valve. This abstract is not to be construed in any way to define or limit the invention set forth below.

Abstract: A traveller device for positioning a sail and having a carrier that is moveable on rollers along a guide track. The rollers project on opposite sides of the carrier and are arranged in spaced-apart relation along the length thereof to engage with rolling contact, longitudinally extending surfaces of the guide track.
