Title: Fastening device for retaining bobbins on spindles
Inventor: ITOH TAKEJI
IPC: D06B5/16
Filed: 1981-12-03
Abstract: A bobbin-spindle is provided with a quick-release fastening device for securing a retaining plate 10 while allowing axial movement of the latter in response to expansion of bobbins or cops. A rod 18 is fitted to one end of the spindle 11 and has a peripheral groove 27. A sleeve 19 can slide on the rod 18 and carries locking balls 26 and a slidable locking ring 28 normally held by a spring 35 in a position in which it holds the balls projecting inwards into the groove 27. The sleeve 19 also carries a compression spring 22 urging downwards a ring 21 which can slide on the sleeve 19 and holds down the retaining plate 10, so that the latter can move against the action of the spring 22. For release, the operator lifts the ring 28, thereby releasing the balls 26 from the groove 27 and pulling the entire assembly consisting of the sleeve 19 and associated components off the rod 18. To refasten the retaining plate 10, the assembly consisting of the sleeve 19 and the components carried by it is pushed onto the rod 18, until the balls 26 engage the groove 27, in which they are locked by the locking ring 28. <IMAGE>

Title: Cooking utensil
Inventor: SHIN-I CHEN
IPC: A47J36/36
Filed: 1982-04-08
Abstract: A cooking utensil, e.g. a kettle has a body 1 surrounded by a skirt 3. The skirt 3 is spaced from the body 1 and a heat conducting medium 2 extends across the space. When the body 1 is placed on a flame, the bottom of the body 1 is heated directly and also heat from the flame or hot air, rising up the sides of the body 1 and constrained by the skirt 3, is absorbed by the heat conducting medium and transferred to the body 1. In this way, the heat is used more efficiently as both the sides and the bottom of the body 1 are heated. This results in more rapid heating of material in the body. A lip 11 seals the top of the gap between the body 1 and the skirt 2 and waste hot air escapes through vents 31. The utensil may also be a saucepan or frying pan. <IMAGE>

Title: Vehicle suspensions
Inventor: STONE RICHARD HENRY
IPC: B62D61/12
Filed: 1983-02-17
Abstract: A vehicle such as a 6x2 tractor having at least three axles is provided with a novel leaf spring suspension (1) for its middle axle. When the load, imposed on the chassis by a semi-trailer, exceeds a predetermined threshold, the free, rear, end of the leaf spring (1) engages the under-surface of the upper portion of a slipper bracket (4) attached to the chassis, and the middle axle takes a proportion of the load. With loads below the threshold, the free end drops through a vertical "air gap" and is held by a lower supporting arm on the slipper bracket, the middle axle being unloaded. The rear, driving, axle is thus more heavily loaded whenever the vehicle is part-laden, ensuring greater traction.
