Patent number: 6279222Abstract: A method of manufacturing a brake pad comprising casting a back plate in a mould. The plate is formed with at least one integral projection which overhangs an adjacent surface of the plate. The mould is formed from frangible material and has a recess in the shape of the projection. The mould is formed from particulate material compressed around a projection made of resilient material which deforms to the shape of the projection. The resilient material is withdrawn to form the recess. Metal is cast in the mould including the recess. After solidification of the metal, the mould is broken away from the projection. The method also comprises pressing a mixture containing friction material and curable material against the plate including pressing the mixture around the projection so that it extends beneath the overhang and curing the curable material to form a block of friction material adhered to the plate.Type: GrantFiled: July 6, 1999Date of Patent: August 28, 2001Assignee: Federal-Mogul Technology LimitedInventors: Kenneth James Bunker, John David Holme, Alan Jeffory Phillips, Hans Fischer, Peter Gareth Denton

Patent number: 5339885Abstract: A metal casting control device is provided for use in conjunction with a semi-continuous metal casting system. The control device is an integral module containing a metal surface elevation sensing device, a valve actuator for positioning a metal distribution control valve, and electronic circuits associated with these mechanical components. The control device module is adapted to be connected to an overhead metal distribution launder by a single quick-coupling for convenient and simple removal and replacement. Calibration of the control device is performed after installation by mounting a calibration target on the metal casting system and vertically adjusting the metal surface elevation sensing device until an integral calibration indicator positioned on the control device indicates that the proper vertical position has been attained.Type: GrantFiled: May 7, 1993Date of Patent: August 23, 1994Assignee: Wagstaff Inc.Inventors: A.
