Title: Improvements in and relating to wireless and like receivers
IPC: H03G3/26
Filed: 1934-07-17
Abstract: 444,391. Valve circuits for wireless reception. LETT, F. T., Joyral, Syke Ings, Iver, Buckinghamshire. July 17, 1934, No. 20959. [Class 40 (v)] A wireless receiver is restored from its muted to its responsive condition only when it is allowed to remain tuned to a desired signal for a predetermined period of at least one half second. The I.F. amplifier V1 of a superheterodyne receiver has a split anode circuit 1, 2, 4, the coil 1 being coupled to the input circuit 5, 6 of the diode second detector 7, 8 feeding the L.F. amplifier V2, the cathode of which is connected to the point 16 on the potential divider 17, 18, 19 connected across the H.T. source, while the grid is connected through resistances 40, 38 to the anode of an auxiliary valve V3. The anode current of valve V3 is controlled in accordance with signal strength by biassing its grid from the load circuit 32 of a diode 31, 24 fed with signals from a selective circuit 29, 30 coupled to the coil 2. In the absence of signals the anode current in the resistance 35 connected between the point 16 and the anode of valve V3 is of such a magnitude as to bias the L.F. amplifier V2 to cut-off. When a signal is tuned in, the current through valve V3 is reduced with a resulting rise in anode potential and the release of valve V2. The time constant of the resistance 38 with its associated condenser 39 is made of the order of two seconds so that the release of the muting bias is delayed by this period. A tuning indicator 36 in the anode circuit of valve V3 is arranged to give an indication of correct tuning, its associated circuits having a time constant of about one tenth second. The diode rectifier 23, 24 rectifies signals fed through condenser 22 from the circuit 1, 2 giving A.V.C. potentials at the point 28 on its load resistance 26, which are delayed by including the resistance 19 in the diode circuit. To prevent the grid of the valve V2 from ever assuming zero bias, the cathode resistance 14 is provided.

Abstract: 411,706. Wheel rakes. PIERCE, P. B., Park House, Wexford, Irish Free State. July 25, 1933, No. 20974. [Class 6 (iii).] A wheel rake of the self acting delivery type is provided with resilient means permitting the two lifting pawls to move into engagement with their respective ratchets independently of each other and also ensuring that the delayed pawl is forced into position between the teeth of its ratchet when its path is clear. Each pawl 2 is freely mounted on a transverse actuating shaft 5 upon the end of which is secured a bar 6 : the free end of the bar overlaps a shoulder 7 on the outer edge of the pawl so that the pawl is lifted by the action of bar when the shaft 5 is rotated anticlockwise. On rotation of the shaft in the reverse direction the pawl is swung about the axis of the shaft 5 by the thrust from the bar 6 exerted through a coiled wire spring 9: yielding is then permitted should, as shown, the pawl engage the top of one of the ratchet teeth. In a modification the shoulder on the pawl is replaced by a shaft carried bar extending into a box-like recess at the end of the bar 6, a helical spring between the side of the box and the bar replacing the coiled spring 9. The pawls are operated from a pedal lever 17 connected by a link 21 to a second link 22 articulated at one end to the outer end of a lever 23 pivoted to the machine frame and at the other to an arm 26 on the end of the shaft 6 : a spring 28 normally maintains the shaft 5 in the position in which the pawls are out of position with the ratchets. When in the raised position the system of links is clear of dead centre locking.
