Filed: 1963-05-16
Abstract: An automatic winding machine having means for the automatic replacement of a wound package with an empty spool and having a conveyer belt to remove from the machine or winding station the doffed package, is provided with sensing means which prevents the transfer of a package from the winding station to said belt as long as there is inadequate belt space in the vicinity of said station. Doffing of a wound package 21 Fig. 1 (not shown) is effected automatically when the package reaches a predetermined size being pushed by a lever 320 through the position 211 to a conveyer belt 307.  The presence on the conveyer of a package 2111 is detected by a pivotally mounted sensing lever 502 to which is attached a blocking member 501 the arrangement being such that the member 501 is in a raised position if the conveyer is loaded and in a lowered position if empty over a predetermined length.  In a modification (Fig. 3 now shown) photoelectric sensing means are used to determine the presence on the conveyer of a wound package.  In a further modification (Fig. 4 not shown) the sensing member operates to prevent doffing of the wound package until the conveyer is clear of wound packages.  The winding machine is stated to be generally similar to that illustrated in Fig. 13 of Specification 971,372 and no detailed description is given of those parts that function in the same manner as in the earlier Specification.

Abstract: 900,612. Radio receiving apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 9, 1959 [June 9, 1958], No. 19705/59. Class 40 (5). In a receiver for a suppressed carrier system the carrier required for demodulating purposes is regenerated by combining the received signal before demodulation with the demodulated signal. As shown, the received signals R are supplied to a conventional balanced domodulator 20 and to a carrier regenerator 21 including a similar demodulator circuit followed by a bandpass filter selecting the carrier frequency, and a clipping circuit. The output of the demodulator 20 is amplified at 23 to provide the output binary signals OIS which are also clipped and fed back to the carrier regenerator 21, the regenerated carrier being supplied via amplifier 23 to the demodulator 20. A start circuit 22 responsive to a series of " 1 " pulses consists of a half-wave rectifier supplied from the bandpass filter so that a capacitor is charged and a normally cut-off valve operates a relay to connect the signal OIS to the carrier regenerator in place of a fixed bias voltage, Fig. 4 (not shown). This ensures that the regenerated carrier is in the correct phase. Specification 900,611 is referred to.
