Abstract: Apparatus for gasifying a liquid with a fluid supplied in liquid form has a discharge conduit for the fluid in which there are one or more restricted cross-section flow paths in a material providing a heat source for converting the fluid to a dry gas. Sealing means are urged resiliently against the open lip of a liquid-filled container into which the discharge conduit projects. Control means for the discharge rate of the dry gas flow from the conduit limit the pressure rise in the container. The sealing means comprises portions of greater flexural compliance permitting excess pressure to be vented from the container. The apparatus may comprise two telescopically movable parts, one holding the liquid container and the other holding a sealed bulb of the gasifying fluid. Said container and bulb are mounted in the parts such that said telescoping movement adjusts itself to accommodate different sizes of container and capsule.

Abstract: The invention is concerned with the reduction of the vibration transmitted from a mechanism having at least one element rotating at a fundamental frequency and one or more cyclically displaceable further elements connected to said rotating element, and in which the displacements of said further elements produce an aggregate cyclic linear exciting force of fundamental frequency and harmonics thereof acting on the same line. To prevent transmission of vibrations produced by said exciting force from the mechanism to its support means, the mechanism is constrained to prevent all degrees of freedom of movement relative to the support means except for movement under the influence of said linear exciting force which is thereby isolated from the support means. The mechanism also has balancing means integral with or attached to said rotating element for balancing any rotating force produced at said fundamental frequency.
