Title: Data record tracking using track identifying information in the gaps between recorded data groups
IPC: G11B21/10
Filed: 1975-06-24
Abstract: 1506229 Data record tracking BATTELLE DEVELOPMENT CORP 24 June 1975 [26 June 1974] 26829/75 Heading G4M [Also in Division G3] A record carrying data in spaced groups on a plurality of adjacent record tracks contains tracking data in the spaces between groups with the tracking data distinguishing a given track from the two adjacent tracks on the opposite sides of the given track. Data, which may be optical marks 12 representing a video signal or may be analog data (Figs. 7, 8, not shown) is recorded in a plurality of tracks A-E in spaced groups. Between the groups is tracking information 18 which in one embodiment is in the same relative location in each track and has an initial reference zone mark 20 followed by a track identifying zone mark 22, 24, 26. The zone marks are staggered for adjacent tracks so that any track is distinguished from its adjacent tracks by the position of the mark. The marks are larger than the data marks so as to be easily distinguishable and so that a correct and an incorrect mark are detected if a sensor shifts laterally from the centre of a given track and with the magnitude of the incorrect mark indicating the amount of lateral shift. In a further embodiment (Fig. 4, not shown) the data groups in different tracks are aligned but the tracking data in different tracks are in different spaces between the groups. In a further embodiment (Fig. 9, not shown) the tracking marks are positioned as in Fig. 2 but the marks have the same lateral dimension as the data marks but have a much longer axial dimension and the sensor is arranged to have increased amplification when the tracking data is sensed. If an optical digital record is used a laser beam is used for sensing and is scanned along the data tracks using a rotating mirror or a rotating plate carrying lenses 50 and is reflected from a tracking deflector 52 on to the record. Reflected light is sensed and a signal fed to a tuning and sequencing logic 58 which detects the initial timing pulse (20, Fig. 2) of the tracking data, if one is present, and supplies timing pulses to integrating sample and hold circuits 64, 66 which also receive the signal from the record. Circuits 64, 66 sample signals on lines 68, 70 only when they receive timing signals from logic 58 and are arranged to sample the zone marks which do not contain the mark corresponding to the track being read, e.g. in Fig. 2 circuit 64 samples zone 22 and circuit 66 samples zone 26 when Track C is being read. The sample value may be stored on a capacitor and may be integrated over a plurality of samplings. Circuits 64, 66 feed a differential amplifier the output of which controls the position of deflector 52 and the value and sign of which determines the amount and direction of the correction. The output of circuits 64, 66 may be gated through AND gates after a predetermined number of cycles or when the total voltage in either circuit exceeds a predetermined value.

Abstract: 472,356. Two part couplings. SOC. BELGE DES LAMPES A INCANDESCENCE LUXOR SOC. ANON. Oct. 9, 1936, No. 27453. Convention date, Oct. 11, 1935. [Class 38 (i)] Electric lamps, which may have a plurality of filaments, are provided with caps consisting of two coaxial members, one having contacts to which the ends of the filaments are connected, and the other contacts for connection with the holder. A contact device between the members allows them to be brought into electrical connection by relative rotation of the members. In Fig. 2, the central contact of a screw cap has attached to it a resilient strip 12, shaped as in Fig. 3. and bearing on the insulated base 6 of the bulb. One end of each of the filaments is connected to contacts 7 or 8 while the other ends are connected to a ring at the base of the bulb, which forms a sliding contact with the outer shell 9. This ring prevents the two members separating and acts as a guide so that the bulb and its cap 5 may be rotated in the outer shell 9. According to the position of contacts 7 and 8 relative to strip 12, either or both filaments may be switched on, or the lamp may be switched off. For a lamp using only one filament 2, the other filament 21 and its connecting wire 15 are omitted. The contact piece 12 is modified slightly for use with a bayonet lamp cap, Figs. 8 and 12, the contact piece 12 being fastened to one contact 19 while the common wire 4 is returned through the shell 16 to the other contact 18. An insulating ring may surround the lower part of the shell to reduce risk of shock when inserting the lamp in its holder.

Abstract: Blocks of treating substances e.g. for degassing, deoxidising, desulphurising, dephosphorising, for grain refinement or for alloying are plunged into molten metal after threading on to a plunger rod which is either made of refractory or has a refractory sleeve over the portion which is immersed in the metal.  The sleeve may be in one piece or may consist of interfitting refractory blocks.  In a modification of the invention when uniform vertical distribution of the treating substance is desired the blocks may be separated by blocks of refractory, and in another modification the rod may have lower sleeving blocks consisting of an inner refractory annulus and an outer annulus of treating substance.  Blocks of degasser may have on their inner surface a thin layer of gas-impermeable material to prevent escape of the evolved gases along the plunger rod, and they may also have fluted outer or inner surfaces to increase the surface area.
