Title. 526,343 R.Bosch Ges. Petrol-feed pumps. Electrically operated fuel pumps are known in which a snap spring carries a contact which opens or closes a circuit dependant upon armature movement. The springs before have been made with the ends mounted unyieldingly so that the spring in action assumes the shape of an S. To simplify the construction the ends of the spring are mounted in a longitudinally resilient manner and a contact is disposed substantially centrally of the spring through which contact the spring is influenced by means of a counter contact associated with the armature. 526,347 J.E.Pollak. Manufacture of spark plugs The electrodes are made of an alloy containing 10-30% of chromium, silicon 1-10% balance substantially pure iron 526,374 E.Tips. Rotary internal combustion engine.
