[Class 65 (ii)] A ball and socket joint which can be dismantled without the use of tools comprises fixed and movable jaws 3, 5, forming the socket for the ball 4, the jaw 5 having an extension 6 sliding within a tubular extension 2 of the fixed jaw 3. The jaw 5 is pressed against 4 by a spring 9 abutting on a slidable piston 13 held in position by a cross pin 14, which slides in slots 15 in the tube 2, and engages at its ends cam surfaces 17 on a sleeve 18 fixed to a manually rotatable sleeve 19. When 19 is turned in one direction, the cams 17 move the pin 18 towards the ball 4, so that the piston compresses the spring 9 against the jaw 5. A fixed annulus 20 prevents axial movement of 18, 19. In another form, the pin 14 is fixed in the extension of the jaw 5 and its ends engage cam slots in the sleeve 19. The outer surface of the tube 2 has axial grooves, into one of which a lug on 19 may slip to fix the latter in adjusted position. In another form, a helical spring is mounted on the tube 2, one end being fixed to the latter, while the other end is fixed to the sleeve 19, so that the spring always turns the sleeve in a direction to force the movable jaw towards 4. In another form, the sleeve 19 gears internally with one or more pinions mounted in apertures in the tube 2 and adapted to rotate an axially immovable nut on a threaded rod carried by the movable jaw. In another form, the ends of the pin 14, which is fixed in a boss on the movable jaw, engage cam grooves on the inner surface of the sleeve 19. Two other cam grooves on 19 engage the ends of a second pin'fixed in a piston normally pressed towards the movable jaw by a spring inside the tube 2. When the screw 19 is turned to release the ball, the piston moves back and compresses the spring, so that when the sleeve is released the spring returns it and moves the jaw 5 towards the ball. In a modification of the last form, the cam grooves are replaced by cam slots in the sleeve 19.

Abstract: 1454025 Vapour burners MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 8 Feb 1974 05967/74 Heading F4T A liquid fuel burner apparatus comprises a housing 11 surrounding a burner body 20 to define air passages 18, 19 supplied with blown air through inlet 15, the body 20 enclosing a vaporizing chamber 45, mixing chamber 80 and combustion zone 90 which respectively communicate via body wall apertures such as 41a, 33 and 23 with the air passages 18 or 19. An electric ignition heater 70 is removably fitted into a retaining tube 71 secured to a wall of vaporizing chamber 45, the gap between heater 70 and tube 71 being subject to the air pressure in passage 18 to prevent fuel vapour leakage through the gap. Heater 70 has an element 72 and a wick 73 positioned adjacent a fuel inlet passage 50, supplied via a line 51 and regulator 52. The latter maintains the fuel at a level L which is lower than the tops of side walls 61, 62 of an intermediate housing 60, but higher than the air inlet apertures 41c. Sufficient air is thus fed into the lower part of chamber 45 to cause rapid formation of a blue flame therein. This is assisted by a rectangular insert 46 of ceramic, or porous or non-porous metal which is initially heated to a high temperature by the flame from wick 73. The air from apertures 41a, 41b, 41c is heated by contact with insert 46. The latter is held in position by a pair of retainers 47, 48 secured to each end wall (20a, Fig. 6, not shown) of body 20. Central cut-outs 46a, 46b in insert 46 assist uniform distribution of the air/fuel mixture. The latter flows upwardly from vaporizing chamber 45, through a restriction 43 defined between plates 35a, 36a, and into mixing chamber 80. Mixing therein is assisted by provision of air inlet apertures 33 in only one vertical wall 32 such that stable combustion cannot occur. Additional apertures may however be provided in the opposite wall 31, staggered in relation to apertures 33. The mixture from chamber 80 flows upwardly through throat 29 for blue flame combustion in zone 90 with additional air supplied through apertures 23, 24. A member 91 having fins 92, 93 promotes combustion by causing turbulence in regions 91a. Member 91 is removably mounted at its ends in brackets 94. Figs. 2, 3 (not shown) illustrate modified arrangements for mounting the ignition heater 70.
