| No. Patentee. Title. 526,384 L.J.Istad Internal combustion engines having cylinders arranged around and parallel to a central shaft. The invention relates to engines of the type having two pistons in each cylinder between which the explosion takes place the pistons operating through connecting rods on two swash plates one at each end of the assembly. 524,403. United Carr Fastener Spring fastener members particularly for securing motor vehicle radiator covers. Corporation. For fastening covers to motor radiator grills, the fastener consists of a piece of metal bent roughly in shape of a V.{VIENNA} At the base of the V is formed a head. The arms of the V are springy and naturally try to move apart. They have corrugations and will grip the ribs of the grill when thrust together and fastener pushed between these ribs. 526,407. W.Griffith & Sons Ltd., and E.Frost. Laminated springs. Shackle of laminated springs are secured to the leaves by means which inter-engage shackle and leaves. Preferably these means engage each blade on its lateral edge. The object is to prevent blades moving longitudinally. 526,451 British Thomson-Houston Speed limiting devices for internal combustion engines. Co.Ltd., and L.Griffiths. The invention is for a magneto cut out when speed of internal combustion engine reaches a predetermined limit. 526,461 E.Bugatti Means for cooling aircraft engines or engine radiators. Cooling air is taken in at leading edge of tail plane led forward through a radiator in the tail, turned through approximately two right angles and discharged through louvres in side of fuselage behind the pilot. | ||
