Abstract: The disclosure of this application is directed to a clean air tube which provides a constantly renewable source of purified air for loading into a medicament syringe prior to use of the syringe for withdrawing liquid medicament from a multi-dose vial. The tube is fitted with a clean-filtering membrane, through which ambient air is filtered upon being drawn into the tube. The disclosure also describes the sequence of steps involved in loading the syringe with clean-filtered air.

Abstract: The disclosure of this application is directed to a medicament injection adjunct which provides a source of sterile air for loading into a medicament syringe prior to use of the syringe for withdrawing liquid medicament from a multi-dose vial. The disclosure also describes the sequence of steps involved in loading the syringe with sterile air. Embodiments involving inclusion of the adjunct in a tandem medicament package and also use of the adjunct in hospital wards or outpatient areas are also described.

Abstract: A method and apparatus for lengthening or shortening a pole supporting lines, such as electric power and telephone lines. The method includes the providing of a stub adapted to be joined in abutting end-to-end relationship with the lower end of the pole to form a lower extension and support for the pole. The pole is raised vertically until its lowermost end portion is clear of the ground so that a lower end portion of the pole can be sized, as necessary, for reception by a mechanism joining the pole and stub. If necessary, the length of the pole is also shortened to provide a desired combined length. After the lower end has been sized, the pole and stub are joined to each other so that they constitute, in effect, a substantially rigid continuation of each other. The pole and stub are then vertically lowered into the ground to a required depth and the ground is consolidated around the base of the stub. The apparatus includes appropriate structure for accomplishing the preceding method.
