Title: Spring-balanced door
Inventor: SCOBARO ROBERTO
IPC: F24C15/02
Filed: 1989-06-09
Abstract: An electric household appliance, such as a dishwasher, washing machine, cooker or the like, has a spring-balanced front loading door (6) which is hinged to the body of the appliance above a recess 5 at the base and also includes at least one tension spring (9) of which one end is connected to the door by means of a flexible cable (10) which runs over at least one return wheel (11), and is characterised in that the other end of tension spring (9) is connected to the body (4) by means of a lever (12) which is pivoted on the body and has a threaded portion which cooperates with a threaded rod (15) having an adjustment head accessible from outside the body and rotatable to adjust the lever between first and second angular positions in which the spring (9) is under minimum and maximum tension, respectively. <IMAGE>
Patent GB-2220047-A (GB)
Title: Improvements in or relating to a roll
Inventor: BRENDEL BERNHARD
IPC: F16C13/00
Filed: 1989-06-22
Abstract: A roll comprises a rotatable shell 1 forming the operative periphery of the roll and a non-rotatable beam 3 which extends through the shell along the length thereof at a position spaced from the internal surface 4 of the shell. The shell can move radially as a whole relative to the beam and is normally supported at a position spaced from the beam by an appropriate support facility. However if the support facility falls or becomes inoperative for some reason then the shell may sink under its own weight onto the top of the beam. If the shell impacts the beam very hard then it may be damaged. The present invention provides means for retarding the movement of the shell towards the beam before the two components engage one another, the retarding means serving to dampen the shell movement independently of the control for the support facility for the shell. <IMAGE>

Title: Bending metal strip to form piston rings
Inventor: BRUCE JOHN ROBERT
IPC: F16J9/12
Filed: 1989-06-23
Abstract: The method at least includes providing rings having a predetermined non-circular profile, by the metal strip being first bent 4 to a uniform radius of curvature at least 2 per cent less than the minimum radius of curvature of a predetermined non-circular profile, then the curved strip being bent back 5 to increase the radii of curvature of all the constituent portions of the strip forming the ring to the desired values of the predetermined profile. First bending is by a fixed abutment 4 and the second bending is by a movable finger 5 operated by a computer-controlled eccentric via a lever. After the second bending, the strip is deflected to one side of the infed strip to enable cutting by a high speed cropper 6. <IMAGE>

Patent GB-2243885-A (GB)
Title: Slack adjuster mechanism
Inventor: TREGONING GEOFFREY ROBINSON
IPC: F16D65/60
Filed: 1990-05-29
Abstract: An automatic slack adjuster mechanism for adjusting the relative angular positions of an input member 1 and an output member 3 has a stepless clutch arrangement having relatively tapered co-axial faces 14, 15 with a spring coil ring 16 therebetween, the stepless clutch being engaged by jamming of the ring 16 between the two clutch faces 14, 15.
