Abstract: A draw latch for attaching one member to another, such as a first panel to a second panel, is unlatched and latched by lifting the latch handle in one direction or the other about a pivot axis, which actuates a pawl member which is pivoted to engage and secure a first catch of a keeper, the handle being pivoted to be secured on a second catch of a keeper, with the pawl being latched against a spring bias provided by a keeper member. The handle is securable by a lock which locks the handle to the second catch to prevent release of the pawl from engagement with the first catch.

Abstract: An apparatus is provided for identifying each of a predetermined plurality of liquid containers, some of which are stoppered and others of which are open-mouthed and for extracting liquid therefrom. The apparatus comprises an upper arm and a lower arm and a sensor responsive to relative motion therebetween, relative motion between the arms causing a container identity signal representative to be generated. A single needle is used to penetrate stoppers when present and extract liquid from the container.
