Title: Improvements in or relating to tuning scales for radio or the like receivers
IPC: H03J1/04
Filed: 1936-05-14
Abstract: 475,121. Adjusting wireless apparatus. FERRANTI, Ltd., and EDWARDS, A. W. May 14, 1936, Nos. 13628/36 and 5489/37. [Class 37] A tuning indicating-arrangement for a radio receiver has a viewing scale bearing visibly all of a plurality of wave-ranges including a range of short waves, and is furnished with a separate movable dial and a source of light serving to illuminate the whole of the viewing scale and also to project an image of some of the indications on the movable dial. As shown in Fig. 1, a translucent scale 1 has long, medium, and short wave-lengths and station names marked thereon, and is illuminated from the rear by means of a lamp 2 and reflector 3. A needle 4 is moved across the scale by means of a cord 5 operated by an arm attached to a shaft driven by the shaft of the tuning condenser. The lamp 2 is carried by a removable bracket 6. In front of the lamp and over the scale is a small reflector 7 which reflects part of the light backwards, which reflected light, together with the direct backward light of the lamp, falls on a condensing lens 8, and thence passes through a graduated disc or annulus 10 mounted on the shaft of the tuning condenser. The light then passes through a focusing lens 11 and is reflected from mirrors 13, 14 so as to form an image on a translucent screen 15. The mirrors 13, 14 may be replaced by a single adjustable mirror. In a modification, Fig. 3, the three separate wave-length scales are engraved on the translucent periphery of a drum 26 mounted on the tuning-shaft 27, which also carries a pointer 4 moving over a translucent fixed scale 1. Within the drum is a lamp 2 and condensing lens 8, by which the light is directed through the scales 1, a focusing lens 11 and is reflected from mirrors 28, 29 on to the screen 15 so as to form an image of the scale corresponding to the wavelength in use. The mirror 28 is tilted by a cam 37 linked to the shaft 30 of the wave-range switch so that the scale reflected on the screen 15 is changed with the wave-range. In a further modification, the graduations are carried on an annular portion of a disc fixed on the condenser shaft, and the adjustable mirror is operated by a cam fixed directly to the shaft of the wave-range switch.

Abstract: 1516643 Fusible cut-outs REYROLLE BELMOS (ASHINGTON) Ltd 27 June 1975 [28 March 1974] 13896/74 Heading H2G [Also in Division B3] A method of making a plurality of fuse elements of the type having a bead of solder on a fuse wire or strip, comprises moving a wire or strip 41 past a heated hob 17 carrying molten solder and periodically moving the wire or strip transversely to deposit a solder bead on it. As shown the wire is carried from a spool 40 (via means not shown) round holders 20 on a wheel 19 and off to a take-up spool 27. The wire is intermittently carried forward by a pin 32 on the shaft of an electric motor 11 engaging slots 35 in the wheel 20 so that each revolution of the motor advances the wheel by 45 degrees to bring a fresh section of wire opposite the hob 17. The pin 32 then disengages from the slot 35 so that during the remainder of the cycle the wire is stationary. During this period a cam follower 30 attached to the yoke arm 23B follows a cam surface 29 to cause the wheel to move down and pick up a bead of solder, after which the next section of wire is advanced and the cycle repeated. The beaded fuse wire is cut into fuses either by hand or automatically by means not disclosed. As an alternative the hob may move instead of the wire. A plurality of solder beads may be added to each wire section.

Abstract: 971,061. Muting circuits. BENDIX CORPORATION. April 8, 1963 [April 18, 1962], No. 13915/63. Heading H3Q. In a muting arrangement which is insensitive to noise the signal from the intermediate frequency amplifier 13 of a superheterodyne receiver is combined in a mixer 17 with the output from a fixed frequency oscillator 18. The difference frequency is taken from the mixer 17 and recombined with the intermediate frequency in a second mixer 19 to produce a signal of frequency equal to that of the oscillator 18. This is combined in a further mixer 21 with the output from a second fixed frequency oscillator 22 and the difference frequency, which is in the audio range applied to a sharplytuned filter 23. The output of filter 23 is rectified by a detector 24 and used to operate a relay 25 which controls the muting of the audio frequency circuits of the receiver. The oscillators 18, 22 are preferably crystal controlled with similar temperature characteristics. In a modification (Fig. 2, not shown) the second oscillator is omitted and the output of the second mixer 19 is combined with a signal derived from the first oscillator in a phase-sensitive detector. The resultant D.C. signal is filtered and used to operate the muting relay. The control voltage may be used for automatic gain control purposes in addition to its use for muting.

Abstract: 495,797. Knot-tying devices. FIELD. ING, J. T. May 21, 1937, No. 14115. [Class 112] A device for facilitating the manipulation of threads to produce a knot comprises a pair of members 3, 4 secured to a base member, the member 4 having a lug 7 with a cutting edge 8, and a spring strip 9 fixed close to the member 4 and bent as shown so that its end 11 presses against its main portion to form a thread gripper; the base member may have a belt or other means for attachment to the person. The strip 9 may be fixed to the member 4 or to the base member, and the members 3 and 4 may be adjustable on the base. To produce a slip knot, the yarns 14, 15 are crossed and wound round the device as shown, the end of the yarn 14 being passed down between the lug 7 and member 3 and brought up into the gripper 9, 11 as shown; the end of the yarn 14 is further pulled up to sever it on the blade 8, the cut end remaining in the gripper so that the loops of the threads can be drawn over it to form the knot and pull it tight, a further pull then removing the cut end from the gripper. A fisherman's bend or back-to-back knot is formed by tying two such knots in opposite ways and sliding the free threads through the knots until the knots come against one another; to facilitate this, two sets of the members 3, 4, 9 may be provided on a single base member, arranged oppositely, and one of these sets may be made shorter than the other. A dog, chicken's head, or winder's knot is formed by making a crossed loop of the two threads side by side and inserting the ends of both threads into the gripper so that they are cut and pulled through the loop. A weaver's knot may be produced by a device having a single member 3 with a pair of members 4, 9 facing each side of it.
