Title: Improvements relating to diaphragms for acoustic instruments
IPC: H04R7/26
Filed: 1924-07-16
Abstract: 241,277. Round, H. J. July 16, 1924. Magnetic instruments ; microphones.-The diaphragm of an acoustic instrument, such as a telephone instrument, is damped over the whole or substantially the whole of its surface on one side by sponge rubber, preferably soaked with oil. As shown in Fig. 1, the diaphragm 1 is firmly clamped between the parts 2, 2<1> of a heavy casing and is damped over its whole area by an oilsoaked rubber sponge 8. The cup 3 containing a resistance varying material such as finely divided carbon is adjustably supported by a stem 6 in a bridge 5 and has a washer 4 held lightly in contact with the diaphragm. Contact plugs 11 are connected with the part 2 and the cup 3 respectively. The diaphragm may be made of brass which is gold-plated on the side in contact with the carbon. Fig. 4 shows a magnetic instrument wherein the diaphragm carries a coil 13 which projects into the air gaps of a magnetic circuit 15 which may be magnetized by a coil 16 or may be of the permanent magnet type. The diaphragm is damped over substantially the whole of its surface by oily sponge rubber 8. The diaphragm may be circular, strip-shaped, conical, or annular and is such that it has a period of 800 to 1500 per second. Preferably, the diaphragm is so proportioned that in the undamped state it has a natural frequency of about 2000 cycles per second, and, when damped, a natural period of about 1500 cycles. The diaphragm may be made of metal such as an aluminium alloy or of a rigid material such as mica or paper heated with a material the registered Trade Mark of which is " Bakelite." One of the Provisional Specifications refers to a gramophone or phonograph sound-box in which the sponge rubber is applied to that side of the diaphragm from which the sound is usually taken. The other Provisional Specification states that oiled felt may be used instead of oiled sponge rubber.

Title: Improvements in Railway Car Couplings of the Automatic Type.
Inventor: BROWN JAMES WILLIAM GIBSON
IPC: B61G3/04
Filed: 1918-10-22
Abstract: 128,822. Brown, J. W. G. Oct. 22, 1918. Couplings, automatic.-Relates to automatic couplings of the knuckle type in which the foot 32, Fig. 1, of the knuckle-piece 30 is formed with an inclined face 54 which is adapted in the closing movement to pass through a gap 35, Fig. 2, in the locking-key 26 and engage an inclined face 34 of the key, whereby the latter is first raised and then drops by gravity into a locking position behind the heel 25 of the knuckle foot 32. According to the invention, a slidable tripper bar 36 for use in uncoupling is arranged to slide in a vertical groove 38 in the key 26. The groove 38 adjoins the gap 35, and the tripper bar is formed with a lug 37 which projects laterally into the gap. In addition, the bottom of the recess is formed with projecting cam surfaces 41, 53, the tripper bar with projecting cam surfaces 39, 52 and a depression 40, and the lug 37 with an upper inclined face 44 and a lower inclined face 42. In the act of coupling, the inclined face 54 of the knuckle foot engages the inclined face 34 and raises the locking-key and tripper bar 36 to the position shown in Fig. 6, at which point the key is ready to drop into the looking position. When the uncoupling gear 46, 47, 48 is operated, the tripper bar is raised alone until it engages the upper end of the groove, and at the same time is first pressed backwards bv the engagement of the cam 39, 41, 52, 53 so that the lug 37 clears the back of the heel 25. At the end of the raising movement, the lug 37 is thrown over the upper end of the heel 25 on to the inclined face 54 of the foot 32 through the engagement of the inclined face 44 of the lug with the inclined face 34 of the locking key, the cam 53 entering the depression 40 as shown in Fig. 8. When the uncoupling gear is released, the locking-key and tripper bar fall by gravity and the lug 37 slides down the inclined face 54 to open the coupling.

Title: Improvements in and relating to transistor amplifiers
IPC: H03F1/34
Filed: 1957-05-31
Abstract: 881,473. Transistor amplifying circuits. MURRAY, J. S. May 30, 1958 [May 31, 1957], No. 17398/57. Class 40(6). In a transistor amplifier comprising an emitter-follower stage 23, Fig. 3, and a subsequent voltage amplifying stage 20, the base-collector D.C. potential of the voltage amplifying stage 20 is stabilized by a D.C. feedback loop including both transistors. The loop comprises the signal coupling path between the emitter circuit of transistor 23 and base of transistor 20 and a feedback path comprising resistors 22, 22<SP>1</SP>, which is limited to D.C. by decoupling condenser 22<SP>11</SP>. In an amplifier having a further direct-coupled stage (Fig. 4, not shown) of either common-emitter or emitter-follower type, the feedback is derived from -a resistor in. the emitter circuit of this transistor. The feedback path may comprise the signal source if this is conductive to D.C., the emitter circuit resistor from which feedback is derived being decoupled for signal frequencies. A tone-control amplifier embodying the invention comprises emitter-follower stages 31, 33, Fig. 5, separated by a voltage amplifier 32. Treble is controlled by an input circuit comprising condensers 45, 47 and variable potentiometer 46; in addition, a drop at 6 dbs/octave above a frequency controllable by potentiometer 41 is provided by treble feedback over condenser 54. The bass is controlled by an input circuit comprising resistors 50, 53, condenser 51 and potentiometer 49 which also forms part of a D.C. and bass feedback circuit comprising condenser 52, resistor 48 and resistor 39 in the emitter circuit of transistor 33. A similar circuit providing two degrees of fixed bass correction for gramophone reproduction (Fig. 6, not shown) omits the treble control networks but includes a further common-emitter voltage amplifying stage. It is for use with an inductive pickup which provides a D.C. path of low resistance and D.C. feedback is obtained by returning the pickup to a resistor, decoupled for signal frequencies, in the emitter circuit of the additional stage. A further embodiment comprises an active filter having emitter-follower stages 31, 33, 55, Fig. 7, and a voltage amplifier 32: feedback, including D.C. feedback in accordance with the invention is provided between the emitter circuit of transistor 55 and the base of transistor 31 via a twin-T network 69-74. The signal input is applied across the emitter circuit of the second transistor 32, the source being of low impedance, and the gain is controlled by means of a variable series resistor 77. Specification 809,207 is referred to.

Abstract: 797,632. Cigarette-making machines. KÍRBER, K. June 11, 1956, No. 17933/56. Addition to 767,275. Class 130. The grooves 4a of a rotaty drum 4 are separated by wide fins 4b which serve as stops against which the end of a multi-length filter rod abuts whilst the rod is cut into doublelength mouthpiece sections F1, each cut-off section being subsequently pushed into a groove 4a and conveyed by the drum to apparatus for 'uniting it to a pair of cigarettes as described in the parent Specification. The rods F, each being of three times the length of the double-length sections F1, are fed through cutting tubes S1, S2 between which operates a knife 10. Each rod first contacts a fin 4b whilst the first section F1 is cut off, the severed section moving into a groove 4a on rotation of the drum so that the rod F moves forward until its end again contacts a fin 4b when the second section F1 is cut off and moved into the next groove 4a. The next fin 4c is narrow to permit the remaining section F1, which doe not need cutting, to move directly into the succeeding groove 4a. The process is the repeated with the next rod F.
