Title: Improvements in loud speakers
IPC: H04R9/02
Filed: 1931-06-24
Abstract: 369,818. Loud - speakers. JENSEN RADIO MANUFACTURING CO., 6601, South Laramie Street, Chicago, U.S.A. June 24, 1931, No. 18266. Convention date, June 27, 1930. [Class 40 (iv).] To obtain accurate concentricity between the inner and outer polepieces of a moving coil loud-speaker, dowel pins and sockets or other positioning means are formed on the parts to be secured together, such as the outer polepiece 7, Fig. 1, and a flange 35 on the casing 5 carrying the inner polepiece 6. In the process of forming the positioning means, the casing 5 is centred by the inner polepiece 6, and the outer polepiece 7 is centred by the opening therein. In the speaker shown in Fig. 1, sockets or holes are formed in the flange 35 of the casing and pins pressed out from or attached to the polepiece 7. The sockets or holes may be formed by a number of drills 45, Fig. 2, carried by a support 46 having a centring member 48 with a socket 49 which engages the inner polepiece 6 before the drills engage the flange 35. Alternatively, the centring means 49<1>, Fig. 4, may be associated with the support 47<1> instead of on the member 46<1>. The dowel pins may be pressed out of the polepiece 7 by extrusion members 57, Fig. 3, on a plunger 56 having a tapered centring member 55 which engages the hole 24 in the polepiece. In a modification, Fig. 5 (not shown), the centring member is associated with the die block instead of with the plunger. Instead of using dowel pins, the flanged part 65, Fig. 7, of the casing 5 may be turned in a lathe about the inner polepiece as a centre, Fig. 8 (not shown), and the edge of the outer polepiece may be turned over, about the hole therein as a centre, e.g. by a plunger and die, Fig. 9 (not shown). To increase the depth of the magnetic field, a supplementary outer polepiece ring 12 may be riveted to the polepiece 7. The moving coil is centred by non-radial spring arms 30, Fig. 1, attached to a ring 32 surrounding the former and to lugs 31 integral with the frame 8.

Patent GB-1604484-A (GB)
Title: Modem with automatic port reconfiguration apparatus
IPC: H04J3/00
Filed: 1978-05-10
Abstract: A modem (11, 13) serving a plurality of inputs/outputs (16) is provided with circuits for automatic, dynamic changeover of the channel or input/output allocation. Standard signals, e.g. "Data terminal ready" signals, represent a command code signal which indicates a commanded input/output allocation to a controlling modem (11). This command code signal is constantly compared with a code signal which controls the actual input/output allocation in the modem (11) and which is stored in a shift register (17). If the command code signal changes, an indication of the change is sent to a controlled modem (13) at the other end of a transmission line (15) and, after a suitable delay time (21), to the shift register (17), whereby its contents are then adapted to the commanded new input/output allocation. During the delay time, the controlled modem (13) changes over to the new input/output allocation. The changeover takes place in a specific sequence in which channels are successively de-activated and, for channel activation, changeover to the operating mode in which all channels are active is always performed initially. <IMAGE>
