Abstract: 1462517 Transistor switching circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 4 Nov 1974 [7 Nov 1973] 47683/74 Heading H3T A drive circuit for a capacitive load C3, e.g. a store comprises: a charging transistor T2 connected between the load and a supply terminal k3; a potential divider R2, R3 connected between the supply terminal and the control electrode of the transistor T2; a capacitor C2 connected between the capacitive load and a tapping point on the potential divider; and a discharge path for the capacitive load comprising a rectifier D and a switch T1. When input k1 is negative, transistor T1 is turned off and capacitor C3 is charged via T2. When input k1 goes positive T1 turns on and the voltage at E falls initially to zero and then rises to half the supply voltage (R2=R3) as capacitor C2 charges. When the input k 1 again goes negative, the potential at B rises to one and a half times the supply voltage to ensure rapid saturation of T2, giving a rapid charge to the load. The connection to load C3 is inductive, and resistor R5 is provided to give critical damping of the resonant circuit formed by this inductance and the load capacitance.

Abstract: 1,005,998. Storage chambers for magnetic tape. AMPEX CORPORATION. Dec. 3, 1963 [Dec. 6, 1962], No. 47747/63. Heading G5R. A magnetic tape loop chamber having an open entry end and a pneumatic outlet is provided with a first pneumatic pressure means adjacent the entry end and adapted to provide a differential pressure across the tape loop, and with a second pneumatic pressure means disposed on opposite sides of the entry end and adapted to narrow the width of the tape loop in the vicinity of the entry end and keep the loop in a free-floating condition. As shown in Fig. 2 an inlet fitting 68 is positioned adjacent the entrance to loop chamber 48 and is adapted to direct air under pressure into the tape loop, which normally intersects an outlet slot 60 open to the atmosphere. Tape guides 62 on each side of the entrance are provided with slots to direct air under pressure to the outside of the loop to keep it away from the side walls of the chamber, thereby reducing frictional drag and the production of electrostatic charge. Air is supplied to the inlet fitting 68 and the guides 62 through a conduit 76 and a pressure regulator 78. The fitting 68 is spaced from the entrance of the chamber to define a slot into which the tape can be threaded, the upper end of the slot being closed in normal operation by a spring- loaded closure arm 88. A metal frame 82 may be mounted over the chamber to provide an effective pneumatic seal. The tape path may run from a reel through a multiple loop mechanical buffering mechanism to a loop chamber, and then past a capstan and pinch roller to a transducing head, and return along a similar path to a second reel, Fig. 1 (not shown).

[Also in Division F4] Apparatus for charging articles on to the conveyer belt 10 of a continuous furnace comprises a vibratory shoot 12 feeding a pivoted, counterbalanced container 14 rocked for discharge by a pneumatic motor 41 through its piston 40 and a cranked arm 36 attached to said container when the latter has a predetermined load of articles, and indexing means for operating said motor when a predetermined length of conveyer belt has passed the charging position. The container 14 is mounted in a frame 18 with counterweight 21 and has a crossbeam 19 formed with knife edges 22 engaging notches in pillars 24, a further counterweight 27 seating in notches 26 on frame 18 allowing for variable quantities of articles being charged. As the container swings downwardly, frame 18 depresses contact 30 of a limit switch 29, cutting off current to the electromagnet of vibratory shoot 12. A cam 49 on the conveyer belt driving shaft then depresses contact 48 of limit switch 47 operating a valve 45 to supply compressed air to motor 41, tilting container 14 and discharging its contents through shoot 15 into conveyer 10. At the same time arm 36 disengages contact 35 of limit switch 33 in series with limit switch 29, thereby preventing supply of current to operate vibratory shoot 12 until container 14 is restored to normal. This is brought about by further rotation of cam 49 depressing contact 48 again and operating valve 45 to reverse motor 41. This motor, valve 45, limit switch 47 and cam 49 together form the indexing means.
