Title: Improvements in and relating to methods of separating into pieces plates of brittle material
Inventor: HOBBS KENNETH
IPC: B28D5/00
Filed: 1959-05-12
Abstract: 925,016. Disintegrating brittle material. MULLARD Ltd. May 12, 1959, No. 16243/59. Class 59. [Also in Groups XXIII and XXXVI] A plate of brittle material having a plurality of score lines extending substantially parallel to one another is separated into pieces by being moved relative to at least one of two members, one on each side of the plate, the shape and resilience of the two members being such that a bending moment is exerted on the plate by the two members and moves progressively along the plate, separating the plate along each score line in turn. As shown, Fig. 1, a slice 20 of a crystal of a semi-conductor material, e.g. germanium or silicon, scored on one face along two sets of parallel, equally spaced lines at right angles to one another, is fixed by adhesive tape 23 to a layer 14 of resilient rubber or felt on a platform 6 which is secured to a shaft 5 journalled in a member 2 which is movable within a casing 12 by a reversible motor 1 and, a cord 3. In operation, when the motor 1 drives the member 2 from left to right, the slice 20 passes under a roller 18 of e.g. steel or cast iron and is deformed sufficiently to crack the slice along the score lines normal to the direction of travel. At the right-hand side of easing 12, a toothed segment 8 fixed on the lower end of shaft 5 engages a stationary rack 17 to turn shaft 5, platform 6, and slice 20 through 90 degrees to a new position where it is held by the engagement of a spring-loaded projection 9 with the second of two depressions 13 in member 2. When member 2 contacts a switch 16 the motor reverses and drives the assembly from right to left, during which movement the slice is separated along the second set of score lines. A second stationary rack (not shown) at the left hand side of casing 12, and a second reversing switch 15, provide for continuous operation; alternatively, switch 15 may also stop the motor to facilitate the removal and replacement of slice 20. To score the slice, the roller 18 is replaced by an array of heads each, as shown in Fig. 3, comprising a diamond fragment 24 mounted in the cutting tip of a spring-loaded holder 26.

Filed: 1966-04-14
Abstract: 1,140,198. Slow motion playback. SONY CORP. 14 April, 1966 [16 April, 1965], No. 16426/66. Heading G5R. A magnetic system for playing back video signals in slow motion from a tape moving more slowly than when recording takes place is arranged so that at least two of the played back signals are selected, recorded in a signal store and played back alternately from the store. In playing back from a video tape in slow motion relative to its recording speed a number of additional intermediate tracks between those representing the originally recorded fields and at an angle thereto are read from the tape, and introduce considerable noise into the played back signal. In order that the slow motion signals may be read out in a substantially noise free manner, the slow motion tracks, SsL, read out by the video tape recorder 1, are passed through selection circuitry 28, and those obtained at times corresponding to the orginally recorded tracks are recorded on a drum 23 which is rotated in synchronism with the video head in the recorder 1. Gates GR1, GR2 in the selector circuit are opened at appropriate times to pass the required track signals by logical circuitry actuated in response to signals PG, provided by the rotation of the video head, and signals TCTL, which indicate the positions of the originally recorded video signals. The selected signals are passed via an amplifier 34 to the recording head 24 of the drum 23. Playback is by means of head 25 and the signals are erased at head 26, operated from the logical circuitry.
