摘要:
A releasable two-part buckle having a first part and a second part is provided. The first and second parts have forward and rearward ends. A hook extends towards the forward end of the first part, while an arm extends towards the forward end of the second part. The hook has a first engagement surface. The arm has a center axis and a loop with a second engagement surface. The arm moves between an engaged state having the engagement surfaces engaged at a contact surface and a disengaged state having the engagement surfaces disengaged. In some embodiments, the buckle is configured so that the contact surface bisects the center axis in the engaged state. In other embodiments, the buckle is configured so that, when in the engaged state, a tension applied to the buckle induces substantially no bending moment in the arm towards the disengaged state.
摘要:
To eliminate a holding frame for a starting wire (20) outside of an elongd discharge vessel (1), the starting wire (20) is directly connected to one of the electrode leads (4, 5), typically niobium tubes, by a bimetal strip (21) which is, preferably, bent in stepped form or Z shape. Under cold conditions, the strip or wire (20) is in engagement with the outside of the discharge vessel (1) to assist in starting, due to its electrical connection via the bimetal strip (21) with one of the electrodes; upon heating of the lamp, the bimetal strip (21) will lift the wire (20) off engagement with the discharge vessel (1) and thus prevent deterioration thereof.
