Abstract: An electro-acoustic transducer of novel structure suitable for automatic assembly is made by arranging with its wall upwards a generally cup-shaped rear cover 20 having a cylindrical wall out-turned at its upper end and extending from the rim of a base divided along a chord 60 into a major segment 61 for receiving an electromagnetic driving unit 30, 34 and a terminal receiving minor segment 62 at a higher vertical level than the major segment 61. The major segment 61 has on its inner face fixing lands 40, 41 disposed symmetrically with respect to a diameter normal to said chord 60 offset away from the minor segment 62 and extending inwards from the side wall. Each fixing land 40, 41 is formed to define a fixing location 64 and having on its face presented to the minor segment an upstanding locator wall 66; 
<??>A yoke and coil sub-assembly lowered into the rear cover is defined by a cruciform yoke plate of magnetisable material having a magnet 50 at its centre with one pair of upturned opposite arms directed along the diameter normal to said chord 60 to said pair of arms defining pole pieces and carrying coils 30, 31 and with the other pair of upturned opposite arms 32, 33 parallel to the said chord 60 and formed with outturned fixing ears 52 that settle directly on said lands 40, 41 behind said locator walls 66 with through-holes 52 therein aligning with said fixing locations 64 of said lands; 
<??>Onto the yoke and coil sub-assembly is placed downwardly an armature 34 formed with depending bearing means that settle on the magnet 50 and permit the armature 34 to rock thereon and a pair of torsion arms extending towards the lands 40, 41 and terminating in fixing ears 35, 36 that settle behind the locator wall 66 on the fixing ears 51 of the coil sub-assembly with through-holes 52 aligning with said fixing locations 64 of said lands. The armature has secured thereto an upstanding connecting rod 34a; 
<??>The armature 34 is mechanically fixed from above the rear cover in tight contact with the yoke plate and the yoke plate is fixed in tight contact with the lands 40, 41 so that the armature is supported for vibration in said rear cover 20. Connector terminals 45 are introduced through said minor segment 62 and electrically connected to the coils. A dished diaphragm 23 is placed downwards onto the rear cover so that its rim 25 settles on the outturned end of the cylindrical wall and the connecting rod 34a projects through a throughhole in said diaphragm. Then the connecting rod 34a is adhered to the diaphragm 23; and a front cover 10 is assembled to the rear cover 20.

IPC: B29D30/58
Filed: 1976-10-08
Abstract: METHOD OF RENEWAL OF THE TREAD ON A WORN PNEUMATIC OF SOLID RUBBER TYRE The invention is concerned with a method of renewal of the tread of a worn pneumatic or solid rubber tyre.  A layer of bonding rubber is applied to the prepared body of the tyre and a prefabricated rubber tread ring is applied.  Gaseous inclusions between the applied layers are avoided or led away and the resulting blank is heated in an autoclave for vulcanizing the bonding rubber.  The tread rins, which on its underside exhibits a rough face of projections and recesses forming a net work of passages, produced in a press mould simultaneously with the production of the tread and kept fit for bonding, is applied to the body coated with the layer of bonding rubber and any gaseous inclusions are led away out of the layers by application of reduced pressure, where upon the lateral outlet openings from the super imposed layers are sealed off, and/or by squeezing out by means of the  exertion of mechanical pressure on the tread.
