Abstract: A stand of a generally hemispheric configuration base. A plurality of clamping legs are provided which are arcuately curved and pass through channels formed in the base. The legs will pass through the respective channels into gripping relationship with the tree trunk when it is inserted into a central containing body in the stand. Thus, the weight of the tree itself serves to locate, hold and place into operation the gripping legs of the combination.

Abstract: A combined power and sensing cable for inter-connecting an EDM power supply and machine tool including a pair of power conducting leads (14,16), each having a non-conducting sleeve (18a, 20a) and a plurality of individual conductors (20) inside each such sleeve. A braided shield sleeve (22) encloses both the power leads. An external insulating jacket (12) encloses the braided shield sleeve (22). A plurality of sensing and control leads (28) are enclosed by a second braided shield (26) which in turn is enclosed by its insulating sleeve (24). The sensing and control leads (28) are aligned substantially parallel to the power conductor leads (14,16) intermediate their respective braided shield (22) and the external insulating jacket (12).

Abstract: An electrical discharge machining electrode for small hole machining. The electrode is of a rod shape and includes a spiral shaped groove extending along the electrode body with a length greater than the thickness of the workpiece. The groove terminates proximate the electrode machining face for receiving a stream of liquid coolant and promoting its flow through the gap during machining. The electrode machining face is blunt and relatively planar in shape.

Abstract: The stand is of a general hemispheric configuration. It is dimensioned with an adapter to handle a broad range of stem sizes and heights of artificial Christmas trees. A principal feature of the stand is the quick mounting and quick release that is made possible by the adapter which is readily expanded or reduced in its diameter when the tree trunk is inserted or removed.
