Title: Method of and apparatus for applying tire components
IPC: B29D30/26
Filed: 1963-06-25
Abstract: 1,040,316. Tyre building apparatus. YOKOHAMA RUBBER CO. Ltd. June 25, 1963 [July 16, 1962], No. 25290/63. Heading B7C. A method of applying tyre bands or a tread band to a tyre building drum comprises the steps of fitting a band 3 over a cylindrical, inflatable bladder 1, positioning a vacuum drum 2, having end clamp means at opposite ends thereof, around the bladder, inflating the bladder 1 to expand the band 3 radially, operating the end clamp means to secure the edges of the band 3 to the cylindrical body of the vacuum drum 2, evacuating the drum 2 to retain the band 3 on the inner periphery thereof, evacuating the bladder 1 so that it collapses, moving the vacuum drum 2 to position the band 3 over a tyre building drum and then releasing the vacuum in the drum 2 and unclamping the band edges so that the band 3 contracts on to the tyre building drum. The bladder 1, the vacuum drum 2 and the tyre building drum are mounted coaxially, the bladder and tyre building drum being fixed while the vacuum drum 2 moves therebetween. The bladder 1 is supported on a barrel comprising two circular end plates 6 which carry a plurality of circumferentially spaced, parallel bars 4. The barrel is mounted on a shaft 9 having an axial bore 10 by which the bladder 1 is connected to a source of vacuum or compressed air. The cylindrical body or inner wall of the vacuum drum 2 is provided with holes 2B while the outer wall has an aperture 2C so that the annular space 2A defined by the inner and outer walls of the drum 2 may be connected to a source of vacuum or compressed air. A cylindrical member 5 may be fitted over the cylindrical body of the vacuum drum 2 on each side of the outer wall thereof for axially sliding movement to serve as an extension of the vacuum drum 2. Each end clamp means includes a number of piston-cylinder assemblies 13-14 mounted at circumferentially spaced positions on one of the extension members 5 and which operate levers 17 having clamping blades 19 at their free extremities. When the levers 17 are operated the tip portions of the blades 19 move radially inwardly along the path indicated at 20 to slip between the edges of the bladder 1 and the band 3, while forcing the bladder wall radially inwards, until the adjacent edge of the band 3 is clamped between the blades 19 and the member 5. When applying a tread band the cylindrical body of the vacuum drum 2 is recessed to accommodate the crown portion of the band. When the vacuum drum 2 is positioned over the tyre building drum the band 3 is transferred by releasing the clamping blades 19 and interrupting the vacuum supply.

Title: Amplifier with mismatched interstage networks
IPC: H03F1/50
Filed: 1954-09-03
Abstract: 757,669. Discharge tube amplifying and gain control circuits. WESTERN ELECTRIC CO., Inc. Sept. 3, 1954 [Sept. 8, 1953], No. 25624/54. Classes 40 (5) and 40 (6). The stages of a cascaded amplifier are coupled over mismatched networks which are damped at the input or output to compensate for the effect of capacitance changes to render the gain-frequency response stable over a wide band with varying gain of the amplifier. Further stabilization is effected by negative feedback due to a partially decoupled cathode load. Discharge tubes V1 ... V5 are coupled over impedance mismatched networks 13 ... 16, the input and output being applied over matched circuits 11, 12. The networks 13, 15, 16 are damped on their output by resistors 29, 45, 52 of a low value, the network 14 being damped on its input by resistor 37. Variations of grid bias due to A.G.C. circuit 81 cause cathode-grid capacitance changes which have opposite effects according as to which side of the filter the damping is applied, Figs. 2 to 5 (not shown). With the arrangement shown, the two effects are substantially neutralized, further stabilization being achieved by cathode resistor 30 which is only partially decoupled by small capacitor 31.

Patent GB-1302490-A (GB)
IPC: H04N5/213
Filed: 1971-04-19
Abstract: 1302490 Limiting circuit SONY CORP 19 April 1971 [3 April 1970] 25760/71 Headings H3T and H4F A noise reduction and synchronization circuit comprises a switching transistor, energized by a T.V. signal via diodes and a smoothing circuit, which is arranged to conduct during any noise pulses in the signal which exceed the amplitude of the synchronizing pulses to reduce their amplitude to a level below that of the synchronizing pulses. The T.V. signal is applied via input terminal 11 to transistor 12 of an emitter follower circuit, and thence to a first voltage divider comprising two resistors 13 and 14 and to a diode 16. This diode reduces the level of both synchronizing and noise pulses and these are fed to the smoothing circuit 17 where all H.F. components are greatly reduced in amplitude. The resultant signal is applied to the base of transistor 22. The signal across resistor 14 is also applied to circuit 23 to set a level corresponding to the level of the circuit available at the emitter of transistor 22, the levels being reduced by diodes 24 and 26 and the signal being passed on to the base of transistor 28. Transistor 28 is the switching transistor and is normally non- conductive, but if the voltage applied to its base exceeds the voltage applied to its emitter by a sufficient amount to overcome the voltage drop between the two elements the high amplitude stray noise pulses switch it on but the synchronizing pulses do not. When transistor 28 is conductive current 47 flows and completes the second voltage divider circuit of resistors 29 and 31 so that the voltage at the output terminal 32 is reduced. By choosing suitable values for resistors 29 and 31 the noise pulse level can be reduced to below the lowest level of the synchronizing portion of the total TV signal. Further because transistors 22 and 28 are connected as a differential amplifier and both supplied by signals derived from the same point, the absolute signal level is of less importance than otherwise and the level of the signal at the output terminal 32 is stabilized. In a modified arrangement, Fig. 5, not shown, a single voltage dropping diode connects the resistors of the first voltage divider to the base of a switching transistor (74) in parallel with the diode and its smoothing circuit. In a further embodiment, Fig. 3, not shown, a transistor replaces diode 16 and a further transistor replaces the diodes 24, 26.

The control electrode 40 is of a material having a high work function with the material of layer 46, so that no current flows between the electrode 40 and the layer 46 but lines of equipotential 60 are generated to constrict or enhance the tunneling current flow 56. In the form shown the control electrode 40 is situated between the tunneling electrodes 42, 44 isolated from both by the insulating material 48, 50, but in a modification (Fig. 2, not shown) the control electrode is situated on the side of the layer 46 remote from the tunneling electrodes 42, 44.
