Abstract: 660,148. Toy yachts. WALLENBERG, V. H. Nov. 10, 1948 [April 21, 1948; Sept. 15, 1948], Nos. 29228/48 and 29229/48. Class 132 (iii). A model yacht comprises two inflatable pontoons between which is disposed a central element supporting a mast and a pivoted centerboard swingable in the plane of symmetry of the yacht. Both the mast 30 and the centerboard 53 are attached to supports that are slidable in a fore and aft direction along a central deck board 1 and the pivoted centerboard 53 is sheeted to the staysail 59. The direction of tacking can be controlled by a sideways pull on a trailing tow rope 73. The mainsail 32 is belayed to a pivoted stern fin 64 held out of the water by the sail. When the tow rope is jerked the main sail 32 is released from the fin to cause wind aft sailing and the fin 64 swings about its pivot to dip into the water. According to a modification the central element is a pair of spaced apart tubes each tube comprising two interengaging parts. In both constructions the masts comprise a number of interengaging elements and the yacht itself is readily reduced to its component parts. The pontoons 5 may be deflated and rolled up.

Abstract: 1431210 Making wheel rims; spinning; rolling; LEIFELD & CO 20 June 1973 [29 June 1972] 29362/73 Headings B3A B3J and B3M A method of making a stepped wheel rim having an upstanding flange or chuck 11 and a base 5 comprises thickening one end of a hollow cylindrical workpiece forming a groove in the thickened portion, reducing the thickness of the central portion of the workpiece and forming the flange or chuck at the other end of the workpiece by a spinning operation with the workpiece mounted between an internal chuck 7 and an external chuck or sleeve 8. The cylindrical workpiece is made by rolling a metal strip into a cylinder and welding a longitudinal seam. Alternatively it may be made from seamless drawn tube. The workpiece is located on the chuck 7 by the sleeve 8 and its free end is thickened by rolls 9, which shape the end to the contour of the chuck 7 as they push back the sleeve, Fig. 5 (not shown). Rolls 10 are then advanced into the thickened portion to form the groove. As they do so the groove end wall is bent slightly outward and the rolls 9 are advanced again to bend it back to its required shape. The workpiece is then clamped on to another chuck and its centre part 5, Fig. 4, is reduced in thickness by draw spinning, so that it has the section of a body having a constant bending moment. The wheel flange 11 is formed by one or more rolls as the workpiece is held between internal and external chucks and the edge of the flange may be cut back if required.

[Also in Group XXV] A bearing pin 21 is rigidly secured to a swivelling member such as an armature 51 of a relay by drilling a hole 23 to a predetermined depth in the end of the pin, inserting the drilled end of the pin into a hole in the swivelling member, and forcing a ball 31 larger in diameter than the drilled hole in the pin entirely into such hole to expand the pin in the swivelling member. As the pin 21 is expanded by a ball 31 at each end, the resulting elastic deformation of the pin and armature 51 causes a throat of lesser diameter than the balls to be formed at each end of the pin so as to prevent the balls from falling out of the holes 23 during operation of the armature. The balls 31, pin 21 and armature 51 are formed from materials having different values of the Modulus of Elasticity and are supported from a frame by means of a bracket 11 in which the armature rotates.
