Abstract: 478,356. Wireless receiving circuits. MURPHY RADIO, Ltd., and ELLIS, H. D. June 17, 1936, No. 16870. [Class 40 (v)] An error-detecting circuit for a superheterodyne receiver having automatic frequency control comprises an oscillatory circuit 2, 3, tuned to the I.F. earthed for alternating currents at one point and loosely coupled to the I.F. circuit 1. The inductance 2 is connected across the anodes of a double-diode 4, a connection between the centre tapping of 2 and the cathode of 4 including a coupling 7 or connection to the I.F. circuit 1, whereby a voltage in phase or opposed phase to that across 1 is also applied to the diode 4. The invention employs the principle that the phase displacement between two coupled tuned circuits is 90‹ when one is in tune with the other, the phase displacement varying with the extent of detuning. The coupling 7 may be replaced by direct connection of the mid-point of the load resistances 5 to the circuit 1 over a condenser, the signal diode being similarly coupled to one side of inductance 2. Or the inductance 2 may be centrally divided by a condenser, the part of the inductance thereby isolated from earth supplying the signal diode ; the AVC diode is then fed over a condenser from the connection from circuit 1 to the cathode of 4. Specifications 332,834, [Class 40 (v)], 443,423, and 457,485 are referred to.

Abstract: 476,943. Fret - saws. CARWARDINE, G. June 18, 1936, No. 16926. [Class 145 (ii)] The blade is connected at its ends to springs both of which are strained in all positions of the blade, the resultant of the forces exerted by them being zero at mid-point so that the tension is constant when the machine is driven at a rate equal to the natural frequency of the system. The blade 7 is secured to chains 12, 13 passing over pulleys, and attached to rods 16, 17. One of the latter is connected by a spring 8 to the frame, and the distant end of the other rod is caused to execute harmonic oscillations ; it also is connected by a spring 9 with the frrme. Harmful vibrations are eliminated when the forced oscillations have the same frequency, as the natural oscillations of the reciprocating system. In a modified machine, Fig. 4, the blade 7 is secured to a spring-pressed rod 10 and to a rod 11 fast to the upper end of a flexible strip 35. A rotatable crank-pin 19 gives harmonic oscillations to a coupling between the strip 35 and a flexible strip 37 connected by a spring 9 with the frame. To prevent damage to the machine shown in Fig. 1, if a blade breaks, part of the rod 17 is made in the form of a telescopic link L, in which a pin 22 on the part 17 projects through slots 23, and is connected by springs with a pin 25 on the part 171. If a blade breaks the parts 17, 171 telescope and a stop pin 26 on the jaw 11 seats in recesses 27 in the head 6, where it becomes motionless.
