Title: Dead track handling
IPC: G11B20/18
Filed: 1968-02-05
Abstract: 1,204,821. Error detecting system in magnetic record medium. RCA CORP. 5 Feb., 1968 [24 Feb., 1967], No. 5596/68. Heading G4C. A record reader system has a reader to sense serially bits which have been recorded on a recording medium, a buffer to assemble and store the sensed bits in serial order of sensing, and a detector operative in the presence of each error within the stored bits in the buffer to produce a signal, in further combination with an inhibit circuit responsive to the signal produced by the detector operative to prevent further operation of the buffer upon the detection of an error. Data from a multi-track magnetic record medium are supplied by a reader to a deskewing buffer 2. The reader detects the occurrence of a zero axis crossing, only a reader system for a single track being shown. The buffer comprises a shift register composed of several flipflop stages 3. The reader logic 1 is arranged to detect an error represented by either a missing zero axis crossing or more than one crossing during a single bit time to set both initial " 1 "  and " 0 " flip-flops to a " 1 " state. When this signal is shifted to the last state an AND gate 6 is enabled to supply an error signal to terminal 7 and to AND gates 8, 9 and via an inverter to AND gate 11. AND gate 9 triggers a counter 20 to enable AND gate 17 to set flip-flop 21, enable AND gate 8 and provide a signal to an inhibit input of AND gate 18 and prevent a resetting signal being applied to the last flipflops of the buffer. If the contents of the last two flip-flops differ or are zero AND gate 6 is inhibited and AND gate 11 is enabled to keep the counter 20 reset and prevent flip-flop 21 from being set. This inhibits AND gate 8 and causes AND gate 18 to reset the last flip-flops of the buffer on the occurrence of each clock pulse.

Abstract: 1,172,668. Light modulation. NATIONAL RESEARCH DEVELOPMENT CORP. 29 Nov., 1967 [1 Dec., 1966], No. 6237/69. Divided out of 1,156,548. Heading H4F. The subject matter of this Specification is identical with that described in Specification 1,156,548, but the claims are concerned with the cavity resonator and crystal assembly used for elliptically polarization modulating the transmitted light beam. Linearly polarized light (polarizer P2, Figs. 1, 2) passes through two KDP crystals X 1  and X 2  exhibiting the direct Pockels linear electro - optic effect and mounted substantially diametrically across a coaxial waveguide M comprising inner and outer conductors I and O respectively. The Z axes of the crystals are parallel to and in the direction of the light beam (i.e. that of crystal X 1  is against the electric field E, and that of crystal X 2  is with), the X axis of crystal X 1  is parallel to the plane of polarization of the light beam and that of crystal X 2  is orthogonal to that of crystal X 1 . The crystals thus give a cumulative elliptical polarization of the exit beam with a modulation wavelength equal to the tuned wavelength of the cavity resonator beam. On reflection from a distant object the light beam passes through a second pair of KDP crystals X 4  and X 3 , the Z axes thereof being parallel and with the beam and the X axes being orthogonal to those of crystals X 2  and X 1  respectively. The reflected beam exits through crossed analyzer P 2 . The second pair of crystals which emphasize or decrease the modulation of the first pair according to the go and return distance of the light beam path. A photomultiplier detection PM allows the detection of cancellation of said modulation and determination of said distance in conjunction with variation of variable path length means VP. In the alternative assembly of Figs. la and 2a only one crystal Z 1  X 4  per beam path is used diametrically placed across the end of a coaxial cavity with the electric field being axially established between the end plate IP of the inner conductor K and the end plate OP of the outer conductor O. The Z axes of the crystals are with the respective beam directions and the X axes are orthogonal.

Class 38(5), A mechanical interlock for a number of pieces of electrical apparatus such as switches 14, 16, 18, 20 comprises a flexible hollow sealed tube 24 which contains a substantially incompressible fluid 26 the volume of the fluid being a predetermined amount less than the volumetric capacity of the tube 24 in its normal configuration. Thus if switch 16 is operated its associated interlock 16a presses on the tube 24 thereby reducing the volumetric capacity of the tube 24 and so prevents operation of any of the interlocks associated with the other switches. The tube 24 while being flexible must, however, not be capable of distension. In another embodiment the interlocks associated with the switches are so proportioned and the volume of the liquid is such that operation. of one switch may prevent operation of any other switch but it may require operation of more than one of these latter switches to prevent the operation of the first switch.
