Title: Electrode for metal halide discharge lamp
Inventor: GRAHAM TIMOTHY W
IPC: H01J61/073
Filed: 1991-12-30
Granted: 2002-09-10
Abstract: A low-wattage metal-halide discharge lamp (10) has a quartz tube (12) of the double ended type hat forms a bulb (14) or envelope, a pair of electrodes, e.g., an anode (30) and a cathode (32), which penetrate in-to an arc chamber (16) inside the envelope(14), and a suitable amount of mercury (98) pies one or more metal halide salts. The electrodes (30, 32) are each formed of a refractory metal, i.e., tungsten wire, extending through the respective necks (22, 24) info the arc chamber (16). The elec-trodes (30, 32) are of a composite design i.e., in the form of a club, with a lead-in wire (34;44) of mall diameter supported in the quartz (12) in the associated neck (22; 24), and a post member (36; 46) of greater di-ameter supported on the lead-in wire (34, 40). The post members (36; 46) are supported out of contact with the quartz of the necks (22, 24) and also out of contact with the bulb wall. The larger size of the post member (36, 46) allows heat at the tip (38, 48) to diffuse back into the post member (36, 46) so that the metal tip (38, 48) will not evaporate.     The narrow lead-in wire (34, 44) keeps most of the heat in the bulb (14) so that flow of heat out of the neck portions (22, 24) is limited. Lamps of this design achieve high efficacy at relative low power (below 40 watts).

Abstract: La présente invention concerne un dispositif à marteau, de préférence un marteau à utiliser au fond du puits composé d'un logement, d'un piston (10), d'un foret (11) et de moyens servant à actionner le piston (10) pour qu'il heurte fréquemment le foret. Dans les marteaux utilisés au fond du puits l'énergie cinétique du piston est transmise par des ondes élastiques allant par l'intermédiaire du foret jusqu'au rocher. Cependant, ladite transmission n'est pas effectuée de manière optimale, puisque le piston n'est pas adapté au foret en longueur et en masse. De plus, le foret ne coopère pas avec le rocher de la meilleure façon. Le but de la présente invention est d'améliorer la transmission d'énergie du piston au rocher à travers le foret. Cela est réalisé en tenant compte de la distribution de l'impédance du piston et du foret du dispositif à marteau.

Filed: 1992-10-27
Granted: 2000-08-01
Abstract: A nail fastener assembly for attaching thin metal sheets includes an axially extending nail with a comically shaped shank having ballistic-like tip at its leading end and a head at its trailing end. A disk is fitted on the leading end of the shank with a sleeve secured on the shank between the disk and the head. When the nail is driven by a setting tool, the sleeve acts on the disk in the region of the tip, so that the transmission of all forces acts on an annular radially outer surface on the leading surface of the disk. The leading end surface of the disk has a radially inner comically shaped first recess and an annular second recess encircling the outer edge of the first recess and spaced inwardly from the radially outer edge of the disk.  Accordingly, the radially outer contact surface bears against the metal sheet being attached and provides high transverse stresses.
