Title: Low voltage radio frequency power amplifier with modulation input
Inventor: BOLT MARK
IPC: H03C1/02
Filed: 2009-06-24
Abstract: A radio frequency power amplifier (RFPA) accepts a carrier wave voltage input (105) to drive switches (102) at radio frequency. The RFPA circuit also accepts a modulation current input (104) connected to a transimpedance circuit (103) which provides a control voltage (112) to a transconductance circuit (101) with switched, complementary current outputs (113 and 114). The current outputs of the transconductance circuit are combined in centre-tapped transformer 100, whose secondary winding is connected to RF output (115). The transfer characteristics of the transimpedance and transconductance circuits are complementary, giving a linear relationship between the peak output current of the transconductance circuit and the input current of the transimpedance circuit. The use of a current mode circuit driving a transformer allows operation from a low voltage supply. The present RFPA may use the same supply as is used to run other digital circuits, avoiding power loss in a regulator or the need for a high bandwidth regulator to track the modulating signal.

Title: Improvements in or relating to automatic frequency control arrangements for frequency-shift telegraph receiver
IPC: H04L27/16
Filed: 1957-03-27
Abstract: 848,559. Automatic frequency control systems, frequency discriminators. SIEMENS & HALSKE A. G. March 27, 1957 [March 27, 1956], No. 10091/57. Class 40(5). In a frequency shift radio telegraphy receiver an AFC voltage is derived by applying the frequency shifting signal to a ring modulator phase discriminator through two paths, one containing a network S whose phase shift/frequency characteristic for the mark and space frequencies differes by 2# radians. The network may be of bridged-T type as shown. The frequency shifting signals are first limited before, application to the phase splitting transformer 3 and push-pull amplifying valves 4, 5. In a modification two multiplexed pairs of frequencies are employed and the number of tuned series circuits 6, 9, 7 10 is increased so that the phase shift increases by 2# between each of the frequencies. The network may be adjustable, in steps of equal frequency spacing, for transmitters having different frequency shifts. As incorrect frequency spacing adjustment will produce an alternating output, corresponding to marks and spaces, superimposed on the AFC output, this may be used for producing correct adjustment of the network. The receiver may also be employed for receiving a carrier signal of constant frequency mid-way between mark and space frequencies, in which case the AFC voltage must be reversed in polarity.

Title: Turbine-type vibrators
IPC: B06B1/18
Filed: 1974-03-08
Abstract: 1460083 Vibrators T S WADENSTEN 8 March 1974 [2 Jan 1974] 10557/74 Addition to 1449208 Heading F2X In a modification of the gas-actuated turbinetype vibrator of the Specification 1,449,208, the noise level is reduced still further by having a muffler housing connected to the rotor chamber outlet and containing a porous muffler pad in which a myriad of flow paths are provided for the effluent gas on its way to atmospheric discharge. In a particular embodiment, an air inlet 40 has an inner portion 44 of reduced diameter which directs a jet of compressed air tangentially on to the teeth 36 of the rotor 30 while an air outlet is provided by holes 42, 43 drilled through the back wall 26 of the housing 10 and spaced 90 degrees in the direction of air inflow from the inlet 40. These holes pass through wall 26 into a shallow annular recess (46) (Fig. 3, not shown) in the rear of the wall 26 in which is removably housed a porous, washershaped filter member 48 as the muffler pad. An axle 22 passes through the rotor 30, and through holes in the centres of end plates 20, 50 and the back wall 26. Nuts 25 are screwed on to threaded end portions 23, 24 of the axle 22 to complete the assembly of the vibrator. Holes 54, 55, 56 drilled through end plate 50 are arranged diametrically opposite the holes 42, 43 in back wall 26 in the assembled condition. The devious flow path through the muffler and the use of plural holes reduces the resonant chamber effect. In an alternative embodiment (Fig. 4, not shown), the muffler pad is housed in a removable cup-shaped housing forming part of the front closure member of the rotor housing. Whereas a maximum noise level of 85 db. is specified for the vibrator (without a muffler) of the main patent, a vibrator embodying this invention has operated continuously at noise levels of 60 to 70 db.
