Title: System for braking an aircraft taxiing on the ground
IPC: B60T8/17
Filed: 1981-08-28
Abstract: The present invention relates to a system for braking an aircraft taxiing on the ground. According to the invention, if an abnormality such as hydroplaning or bursting of a non-braked wheel 2 is detected, the speed most representative of the real speed of the aircraft with respect to the ground is memorised in one of two memories 14 and 15. This memorised speed is regularly reduced to allow braking for the whole duration of the disturbance, avoiding locking or elimination of braking of the wheels 4 of the main landing gear. The invention is more particularly applicable to the braking of wide-body aircraft. <IMAGE>

Title: Vacuum belt filter
IPC: B01D29/00
Filed: 1981-10-30
Abstract: Slurry required to be filtered is supplied to a downwardly inclined feed section of intermittently-moving belt 25 by way of supply pipe 20. The belt then passes under roll 40 and along at least one vacuum box 17, which to ensure even distribution of slurry over belt 25 is inclined upwards in the direction of belt movement at 4 DEG  to 20 DEG  to horizontal (an angle of 8 DEG  being illustrated). Subsequently resultant filter cake layer is subjected to mechanical dewatering by raising a lower pressure plate 23 to press belt 25 with filter cake thereon against underside of counterplate 24. Stepwise progression of belt 25 in direction indicated by arrow 36 is achieved by increasing and decreasing extent of bight 29 in return run of belt 25 by successive clockwise and anticlockwise movement of arms 31 actuated by ram 32. Unidirectional devise 33 prevents movement of belt 25 in opposite direction and belt length is successively taken up and given out by tensioning roller 39 rising and falling in slot 14. In further embodiments the belt 25 moves continuously and the vacuum boxes 17 and pressure plates 23, 24 move cyclically, firstly in synchronism with the belt while applying a vacuum and pressure respectively and, secondly, when these are released, back to their starting positions. <IMAGE>

Title: Preparation of non-cross-linked polymers and moulding process therefor
Inventor: ATKINSON IVOR B
IPC: C08L33/14
Filed: 1980-08-06
Abstract: A moulding process is described which comprises introducing into a mould an essentially non-cross-linked polymer of an ethylenically unsaturated hydroxy ester in the presence of an acidic or basic esterification catalyst and subjecting the polymer to conditions under which cross-linking takes place. The non-cross-linked polymer is prepared by a process wherein a monomer mixture comprising an hydroxy alkyl acrylate or methacrylate or an ethylenically unsaturated amide is polymerised in a solvent which is a solvent for the monomer but not for the resulting polymer at the polymerisation temperature, the polymerisation being carried out in the presence of a colloid stabiliser so that polymer precipitated from the solvent as polymerisation proceeds forms a flocculated or colloidal dispersion of polymer in the solvent.
Patent GB-2135477-A (GB)
Title: Motor control system
Inventor: NEWMAN PERRAN VINCENT LEONARD
IPC: G05B19/21
Filed: 1983-02-22
Abstract: Method of controlling the position of the rotor of a motor connected to a position transducer which serves to produce a cyclic signal in which at consecutive zero crossings the time derivative of the output signal changes. The method comprises controlling the motor current in a servo loop in dependence upon the output of the position transducer whereby to define a plurality of positions of stable equilibrium spaced from one another by points of unstable equilibrium. In order to move the rotor by one increment, a current pulse is applied to the motor to provide an initial bias to deflect the rotor in the direction of desired motion and the polarity of the feedback signal in the servo loop is reserved to change the point of stable equilibrium into one of unstable equilibrium and the adjacent point of unstable equilibrium into one of stable equilibrium. Thus, the rotor moves rapidly to the next zero crossing at which point the rotor is prevented from further movement by the servo loop.
