    Abstract: 919,726. Spiked-plates. MULLER, M. E. A. July 28, 1960 [July 29, 1959], No. 26353/60. Class 89 (2). A spiked-plate 1 for interconnecting parts 11, 12 comprises a substantially U-shaped body, the limbs 2, 3 of which are formed with teeth 4, 5. Teeth 5 lie in the planes of the limbs and teeth 4 lie in planes extending inwardly from the limbs towards the central axis of the plate. In a modification, the planes of teeth 4 are parallel to the central axis. When driven, the teeth bend into the thickness of the parts, and the back of the plate may be flattened by hammering to form a stiffening groove 10.

    Abstract: The rig has the mast (2) at the centre of gravity (19) of the sail surface able to turn on the top of the auxiliary mast (1). The sail setting angle can be altered by a sail boom (3) which is attached to the foot (6) of the mast so that it can turn, or by a turning movement of the mast itself with the boom fixed to the foot, about its longitudinal axis, with two steering rods. A combination of these two systems is also possible. The required setting force can be achieved by means of various ropes or by auxiliary power. The mast has two fixed points in the vicinity of the turning axis, corresponding on alternate sides to two other opposite fixed points on either side in the upper part of the auxiliary mast.
