Abstract: Assemblies in accordance with the invention can lead to an exceptionally easy to use, safe, and convenient system and method of applying a fixed dosage of chemicals to which a user might wish to avoid contact, such as parasiticides. In the present invention, a fluid, such as a pesticide or parasiticide, glue, solvent, lubricant, medicament and the like is loaded into a fluid reservoir and the reservoir sealed. The reservoir can be attached to a cap-applicator structure which is in an inactive configuration. In the inactive configuration, a piercing tip remains poised over the reservoir in an inactive configuration without forming an opening in the reservoir. The cap-applicator can have a sharp intsernal piercing tip capable of piercing the reservoir when the assembly is converted into an active configuration. This will allow the user to dispense the liquid out of the reservoir through the applicator.

Abstract: A movable-window safety device for arresting upward movement of a power-driven window glass in a motor vehicle body in the event of obstruction in the window opening comprises a resilient channel for receiving the window glass and which is mounted in a rigid window frame. The base of the resilient channel comprises an electrical detecting member housed in a hollow chamber. The side walls of the resilient channel extend proud of the sides of the rigid window frame and carry curved-over outer lips and inner lips. An obstruction in the window opening is carried upwardly by the window glass and applies a force to one or other of the side walls of the resilient channel, according to whether the obstruction extends inwardly or outwardly of the window opening. The resultant force is applied to the detecting member.
