Patent GB-810308-A (GB)
Abstract: 810,308. Ignition systems. GURVIZ, A. Nov. 17, 1955 [Nov. 19, 1954], No. 32970/55. Class 7(4) The privary winding U1, Fig. 1, of a peaking transformer T is connected across an A.C. generator G, and the secondary winding U2 is connected to the sparking plug of a single-cylinder engine or to the distributer of a multi-cylinder engine. The arrangement may be such that the distributer may be dispensed with. The abrupt change in permeability of the magnetic material used for the core of the transformer T upon reaching saturation level causes a pulse of high voltage to build up across the transformer's windings superimposed on the generator voltage causing a discharge in the sparking plug. An impedance Z which may be the selfimpedance of the generator prevents the pulse from short-circuiting back on the generator. The voltage across the secondary winding of the transformer is a function of the generator speed, and at a certain speed the voltage caused by complete reversal of the polarity of the flux in the generator core will produce a spark. The transition from zero to maximum flux will produce a spark if the generator speed is approximately double the above minimum. Since the minimum speed is set by other considerations this is the lowest speed for which automatic advancement of ignition timing may be obtained. If automatic advance is required for a higher speed ratio, the air gap between the rotor and stator of the generator may be varied as by using a contoured ring 3, Fig. 2 (not shown). If the same timing is required at all speeds, a rectifier is connected in series or in parallel with the transformer primary to suppress either the pulse produced by complete reversal or that of transition from zero to maximum. Timing may also be varied by inserting capacities and/or inductances in the circuit. If an inductance is used, timing may depend on a variable air gap in the inductance or on the choice of the material used for the core of the inductance. In Fig. 11a a variable capacitor C and a variable inductance L are used, in Fig. 11b (not shown) the capacitor C is connected across the secondary of the transformer. A further method of varying the timing is by manually or automatically altering the relative angular positions of the rotar and stator of the generator. To eliminate drop in the voltage across the sparking plug due to reduction in the value of the resistance R2, Fig. 10, of the insulation a condenser C and a discharge device S2 are added. The potential of the condenser C is about the same as that of the generator. Discharge across S2, the striking voltage of which is greater than that of the sparking plug S1; occurs whatever the value of R2.

Title: Method and apparatus for recording digitized information on a record medium
IPC: G11B27/10
Filed: 1981-08-03
Abstract: At least one channel of digitized information is recorded in at least one data track on a record medium by forming data blocks, each containing a predetermined number of data words representing the digitized information, and recording successive data blocks in at least one data track. A block address also is generated to identify each of the respective data blocks, this block address also being recorded with the data block in the data track. A predetermined number of successive data blocks is recorded in the data track in a sector interval. A control signal having at least a sector address for identifying the sector interval also is generated, and this control signal is recorded in a separate control track, successive control signals being recorded in successive sector intervals. The least significant bit of the sector address is coincident with the most significant bit of the block address, such that the block address is repeated with a periodicity related to the sector interval. The combination of the sector and block addresses is used to access a desired one of the recorded data blocks. <IMAGE>
