Title: Shell boilers
IPC: F22B31/00
Filed: 1980-04-30
Abstract: A horizontal shell boiler has within the shell 3 a horizontal furnace section 1 in which a fluidised bed 2 is situated. At one end the furnace section 1 communicates with a flue gas transfer section connected to flue tubes extending horizontally through the boiler fluid above and around the furnace section 1. The furnace section 1 is divided into two portions by a row of inclined water tubes 4 the portion above the water tubes acting as a flue gas flow passage 5 leading (5) into the flue gas transfer section. The end of the lower portion is closed. Combustion gases leave the fluidised bed 2 in a vertical direction and pass between the inclined water into the passage 5 tubes 4, and then travel horizontally along to the flue gas transfer section and do not have any significant tendency to entrain the material of the fluidised bed (2).

Title: Motion compensating system
IPC: B63B27/36
Filed: 1980-05-02
Abstract: This invention relates to control system for motion compensation arrangements designed to provide stabilisation of a body suspended by means of a cable from a support structure which is liable to uncontrolled movements. The invention finds particular application in the stabilisation of bodies suspended in the sea from vessels subject to wave motion and wind and current forces. The control system includes a supporting cable 2 extending between a winch 3 and a pulley 4 from which the body 1 is suspended, and forming a loop, the length of the loop being resiliently displaceable from an equilibrium value, wherein said length of loop is altered in controlled response to both the measured vertical acceleration of said pulley 4 and to the measured amplitude of oscillations in the length of said loop. The control system may also incorporate means for compensating for long- term drift and for the effects of friction. <IMAGE>

Title: Electric switches
IPC: A47J27/21
Filed: 1979-08-15
Abstract: A switch assembly, for an electric kettle, includes a switch actuating lever 70 pivotally mounted on a body 73 for movement between an off position in which the lever causes a pair of contacts to be held open, and an on position in which the contacts are closed.

Title: Device for making a transverse cut in a moving object
IPC: A24C1/36
Filed: 1980-11-28
Abstract: A device for transversely cutting cigars, or other objects comprising a filling surrounded by a sheath, in the course of their manufacture comprises a chain conveyor 11 having recesses 12 for holding the cigars and two rotary cutter holders 15 one above and one below the conveyor 11. Each holder 15 carries a series of cutting members 14 each having a V-shaped cutting edge 16 and the speed of rotation of the holders 15 relative to the speed of the conveyor 11 is such that, during cutting each cutting edge 16 has a component of movement which is synchronous with the movement of the conveyor 11. This combined with the angular movement of the members 14, which co-operate with each other in pairs, one above and one below the cigar, results in a particularly effective cutting action and also enables cutting to take place without interrupting the conveyance of the cigars and holding them stationary while they are cut as has generally previously been necessary. <IMAGE>

IPC: D05B81/00
Filed: 1983-10-21
Abstract: The apparatus has a three- dimensional form with a peripheral surface which generally corresponds to the contour of the article to be formed. Pattern pieces are picked up and positioned on the form by a manipulator which has an articulated arm carrying a pickup device and which operates in response to signals from a programmable controller. A seaming tool carried by another manipulator moves in working relation to pattern pieces spread on the form to join the pattern pieces along seams which generally follow the contour of the form in response to signals from the controller. Another manipulator moves a pressing head in pressing relation to pattern pieces spread on the form in response to signals from the controller to press the pattern pieces or the article made from the pattern pieces to remove wrinkles therefrom.
