Title: Improvements in or relating to radio receivers
Inventor: BROWNING ROY VICTOR
IPC: H03H7/01
Filed: 1949-07-06
Abstract: 674,635. Selectivity control. KOLSTER BRANDES, Ltd. June 30, 1950 [July 6, 1949], No. 17856/49. Class 40 (v). In the intermediate frequency stage of a receiver adapted to receive A.M. or F.M. signals, a pair of transformers tuned to the appropriate A.M. and F.M. I.F. frequencies are arranged so that the primary of the F.M. transformer can be switched in series with the secondary of the A.M. transformer to vary the selectivity of the latter. With the ganged switches in position 1, the amplifier will pass F.M. signals through the transformer comprising primary 23 and secondary 24 or A.M. signals through the transformer comprising primary 25 and secondary 26. Upon the switches being moved to position 2 the inductor of the F.M. primary 23 is connected in series with the inductor of secondary 26 to increase the coupling in the A.M. transformer and thus decrease the selectivity. Any detuning may be overcome by a variable capacitor. The transformers preferably consist of coils on a former with adjustable magnetic cores for tuning, Fig. 1 (not shown). The coils may be adjustable on the formers and the formers may be moved relative to one another to vary the selectivity further.

Abstract: 519,159. Rotary-absorption dynamometers. WINTHER, M. P. June 16,1938, No. 17952. Convention date, April 9. [Class 106 (ii)] [Also in Group XXXVII] The apparatus is provided with means by which the speed-torque curve for the dynamometer may be matched with that of the engine to be tested. A stator case 11 rocks in bearings 13 and carries the usual arm engaging torque-measuring scales, not shown. The prime mover to be tested is connected to the dynamometer shaft 17 upon which is carried a rotor 19 having salient poles 21 adjacent ones of which are of opposite polarity. Each pole has a winding 23 excited by current from .a' circuit 55 through brushes 25 and slip rings 27. The flux from the poles passes through the watercirculating ring and metal of the case inducing eddy-currents in the ring. Grooves 31 form passages for cooling water and are connected with the entry box 33 as set out in Specification 518,863. A centrifugal governor G driven from shaft 17 moves a bell-crank 47 the contactor 49 of which engages the last of a row of separate spring contacts 51 of a shunt contactor K. Each pair of contacts when successively closed is shunted across a respective resistance 53 in circuit 55, so that at low speeds the dynamo has less excitation and resisting torque and as speed rises the torque increases. The resistances may be selected to give any desired speed-torque curve. In one form each resistance 53 is provided with a manually adjustable shunt for making adjustments. A manually operated rheostat can be used either with the automatic one or when belt 37 is removed. The dynamo 65 is driven by stepped pulleys from shaft 17. A field control rheostat 71 is provided. The above described control is also described as applied to a toothedrotor type of apparatus in which the coils are In the stator. In, another form the salient pole type is combined with the toothed rotor type on the same shaft. A form of governor apparatus is described specially for use in testing marine engines the torque of which rises as the square of the speed. Four seven-leaf banks of contacts 51 are used 79, 81, 83, 85. Each bank contains seven slightly spaced contacts 51. Adjustable abutments 91 are provided for the four rows. Wires lead from the ends 93 to taps 95 of resistances 97. A lever 99 is keyed to shaft 101 to which is keyed a fork 45 moved by the governor sleeve 41. A spring 43 restores the weights 103. A pressure plate 113 contacts the end contacts 51 in each of the four rows. The plate 113 carries spaced extensions 115 between which is a roller 117, and which are connected by a link 119 to a spring 121. A bell-crank 127 pivoted to the case at 125 carries a fulcrum roller 129 on which rests a link 131 pivoted at 133 to lever 99. The outer end rests under roller 117. When the lever 9 is turned counterclockwise the plate 113 is forced up to move contacts 51. The position of roller 129 can be adjusted by moving the lever 127 by turning milled screw 137.

Filed: 1952-07-21
Abstract: 707,949. Driving sound film or tape. STRAUSS, P. July 21, 1952, No. 18417/52. Class 40 (2). A mechanism for producing sounds in dolls and similar toys, comprises a long endless sound film or tape 80 engaged by a sound-box 100 and driven piece by piece by a coiled spring 24 which is wound up by means of a ratchet and a falling weight 70 in the process of returning the latter to its initial position, Fig. 3, after the toy has been inverted and restored to its normal position. During invertion the weight 70 slides up the support plate 20 to a piston. in which a projection 75 on the weight 70 becomes engaged with a spring latch 46 on a member 42 connected to a belt 40 attached to a drum 22 containing the spring 24, one end of which is connected to the drum 22, and the other to a stationary shaft 25. When the toy is restored to the normal position the weight 70 descends and takes with it the member 42 which is slotted to embrace a depending member 50 connected to the plate 20 by a curved spring 60. During the descent of the weight 70 the drum 22 winds up the spring 24, a ratchet pawl 30 on a flange 31 of the drum 22 sliding freely over the teeth of a ratchet wheel 27 connected by a key to a gear wheel 26. When the weight 70 comes into contact with the curved spring 60, the latter is straightened sufficiently for the depending member 50 to push the member 42 and latch 46 thereon out of engagement with the weight 70 so that the member 42 is free to return under the influence of the wound up spring 24. As soon as this commences to happen, the pawl 30 engages a tooth in the ratchet wheel 27 and rotates, through step-up gearing, a sprocket wheel 85 whose teeth engage the film 80 and draw it past the stylus 99 of the sound-box 100. The length of film moved past the sound-box is sufficient to reproduce a phrase or sentence on the film, which is long enough to contain many different phrases or sentences and is arranged backwards and forwards over pulleys 91 to 97 inclusive and drum 28.
