Abstract: 1326573 Pulse generators TELEFUNKEN PATENTVERWERTUNGS GmbH 29 Oct 1970 [29 Oct 1969] 51503/70 Addition to 1279159 Heading H3T [Also in Division G4] In a modification of the pulse generator of the parent Specification 1,279,159 having a trigger stage 1 for periodically interrupted operation of a plurality of parallel connected loads such as lamps L 1 , L 2  or L 3 , L 4 , a resistor Lk in the form of an indicating lamp is connected between the loads and the supply voltage in the intervals in operation such that during the intervals in operation a measuring current flows through the loads to cause a volt drop which is supplied to a switch T 3 , T 4  so that if one or more of the loads fail the state of the switch T 3 , T 4  changes during the intervals in operation in comparison with that with intact loads so that a voltage divider R 1 , R 2  alters the charge on the timing capacitor C so as to alter the pulse frequency of the generator. With the switch S L  as shown T 1  is on and T 2  is off. Closing switch S L  to a or b turns T 1  off and T 2  on so that relay contact S R  closes to light the lamps L 1 , L 2  or L 3 , L 4  selected. The timing capacitor C operates to switch T 1  o n and T 2  off releasing contact S R  and switching off the load lamps L 1 , L 2  or L 3 , L 4 . Indicating lamp L K  lights and the voltage at the emitters of transistors T 3  and T 4  with the loads intact make T 4  on and T 3  off. When one or more loads fail the voltage at the emitters of T 3 , T 4  make T 4  off and T 3  on to alter the time constant of the pulse generator so that the frequency rate of illumination of lamp L K  is increased to indicate this failure. A resistor R 8  of relatively high value ensures that the pulse generator operates even on failure of the tell-tale lamp L K . The pulse generator 1 may be in integrated circuit form.

Abstract: 1,172,518. Television; transistor amplifying circuits. ELECTRIC & MUSICAL INDUSTRIES Ltd. 1 Dec., 1966 [7 Dec., 1965], No. 51742/65. Headings H3T and H4F. The Specification describes a transistorized television D.C. level restorer incorporating a D.C. amplifier following a clamping circuit. Due to the susceptibility of D.C. amplifiers to variations in supply voltage, the level of the output signal may vary. The reference voltage to which the video signal back porches are clamped is made a function of said supply such that said variation of the output signal is compensated. The D.C. amplifier comprises transistors 3 and 4, with load resistors 15 and 19, temperature compensating diodes 6, 8 and zener diode 7, and negative feedback loop 14, 13, 26. The output appears at 29. The reference voltage is set by potentiometer 11 in dependance on the nominally constant supply voltage of 60 V. The video signals at input 28 are applied to the D.C. amplifier via transistor 2 and have their back porches clamped to the reference signal by means of synchronized switching pulses at 27 causing transistor 1 to conduct.

Spun yarn is wound on a spool 41 mounted on tilting arms 42, a switch 5 is associated with the arms 42 and operated by an operating part 45 on the arm 42 to enable an attendant to control the fibre feed with the same hand that he lifts the winding spool while leaving the other free to feed the yarn end into the spinning chamber. The circuit of the switch 5 has a latching relay 50 and bypasses a yarn tension feeler 3 so that feed of fibre may be effected despite there being no yarn tension. When yarn tension is restored the feeler 3 switches over delatching the relay 50 and hence operating thereafter as a stop motion. The switch may be incorporated in the arm 42 the operating part then being a button (81) mounted thereon, Fig. 4 (not shown). The arm 42 may be maintainable in its elevated position by a fixed ratchet wheel 6, Fig. 3, in cooperation with a paw1 60 mounted on the arm and serving also as the operating part. The switch may alternatively be incorporated with the stop motion feeler and operated by a coaxial operating cable, Fig. 2 (not shown).
