Filed: 1922-08-18
Abstract: 205,938. Hart, H., (Mergenthaler Linotype Co.). Aug. 18, 1922. Keyboards and escapements for type-bar making machines. In machines having a single keyboard and one or more auxiliary magazines located at one side of the standard magazine or magazines, the Keys that normally control the release of lower-case matrices from the standard magazine are adapted, in addition to their normal function, to control the release of upper-case matrices of the same fount from the standard magazine or, alternatively, to release matrices of a different fount from the auxiliary magazine. The different functions of the lower-case keys, which occupy the left-hand half of the keyboard, are effected by means of a series of transverse rock-shafts 12, Fig 2, mounted in a frame 11, which is adjustable horizontally within an outer fixed frame 6. Each rock-shaft has three arms, one arm n<4>, Fig. 5, being adapted to be engaged by a spur n<2> on a lower-case escapement-rod n<1>, a second arm n' being adapted to engage and operate by means of a spur n<6> one of the upper-case escapement-rods n<5> of the standard magazine 1, and a third arm n<10> being adapted to operate one of the escapement-rods n<8> of the auxiliary magazine 2. When lower-case matrices are required, the rock-shafts are inoperative, the arms n<4> being clear of the spurs n <2>, as shown in Fig. 5. The frame 11 may be shifted into either of its other positions, to bring the rock-shafts into use, by means of an eccentric shaft 16 and a band-lever 14. When upper-case or auxiliary-magazine matrices are required, the lower-case escapementrods are disconnected from their escapements by means of a slotted guide-plate 17, which is operated from the sliding frame 11 by cam-slots 18 and pins 19. A small group of escapement-rods, corresponding to punctuation marks, is retained in use when either lower or upper case matricesare being released, but is disengaged, when the auxiliary magazine is in use, by means of a sliding comb-plate 23 operated by a lever 24 from the hand-lever 14. The rock-shafts 12 are detachable from the machine together with the side-plates of the frame 11.

Abstract: 809,945. Driving and heating arrangements in textile spinning &c. machines. SCRAGG Ltd., S. & E Aug. 8, 1956 [Aug. 9, 1955], No. 22877/55. Class 120(2) An attachable unit 'for a yarn winding and twisting machine comprises a yarn forwarding means, a yarn heating surface and a belt driven yarn twisting spindle which are carried by a fixed vertical column and arranged so that movement of the spindle relative to the column disengages it from the belt, renders the forwarding means inoperative and, optionally, withdraws the yarn from contact with the heating surface. In the unit shown attached to a spindle rail R, yarn is drawn from a package P (carried on a bracket C secured to a column T) over a spring- loaded guide SG and a fixed guide by a yarn forwarding wheel U, then passes over an arcuate electrically heated surface within a slotted, hinged casing of a heater E, is led through a guide 52, around a radial or cross-member 54 or 53, Fig. 4 (not shown) of a twister head, through a hollow false-twist spindle S, past a guide 55 and around a yarn advancing wheel L, thence through guides 56 and 57 and a serving mechanism 58 to be wound on a mandrel 59 driven by a bowl 51 which also drives a wheel D in turn driving (through chain connections) the wheels U and L. The spindle S is carried in bearing housings 11 and 12, Fig. 3, secured by spring clips 15 and 16 on a cradle 13 carried by an arm 23 having a pivot pin 24 rotatably mounted in a base casting and urged by a spring 26 abutting a peg 25 so as to press the spindle in engagement with a driving belt B against the reaction of a jockey pulley J. Movement of an operating arm 33 into the chain-dotted position, Fig. 2, rotates a shaft 32 to rock a cam 31 which co-acts with the peg 25 to force the cradle 13 into a stable position in which the spindle S is disengaged from the belt B. The movement of the peg 25 in turn displaces the end of a rod 46 the movement of which away from the solumn T displaces the eye of a leaf spring 43 and therewith a rod 42 and yarn engaging member 41 (into the chain-dotted position) whereby the yarn is removed from the heating surface; upward movement of the rod 46 lifts a lug 47 to rock a pivoted head casting and lower the wheel D from engagement with the bowl 51. The action of the cam 31 and its associated parts may be adjusted so that, when the spindle is re-engaged, it rotates immediately before the yarn is returned into contact with the heating surface. Specification 809,946 [Group XXXIV] is referred to.

Title: Improvements in electrical vibratory devices such, for example, as loud speakers
IPC: H04R3/08
Filed: 1928-08-10
Abstract: 320,713. Trouton, M. Aug. 10, 1928. Magnetic instruments; repeating and amplifying systems.-In a vibratory device, such as a moving coil loud-speaker, for the interconversion of sound and electrical energy means are provided to obtain a corrective effect dependent upon the disconformity between the applied and generated oscillations. The Figure shows a wireless receiver 1 operating a moving-coil loudspeaker 9. The output of the receiver 1 is applied to valves VI, V2, in parallel, one having the coil 8 of the loud-speaker in the output and the other an unloaded moving-coil 11, parts of the coils are associated with cylindrical electrodes 13, 14 with which they form two condensers which form the input to an amplifier 7, and the coils 8, 11 are so connected that they vibrate in phase opposition. When the coils move to the same extent the total capacity across the amplifier 7 is constant but disconformity causes the amplifier to add energy to the input of the coil 8 so as to produce a corrective effect according to the nature of the disconformity. In a modification (Fig. 2 not shown) the moving-coil of the loud-speaker forms with a fixed electrode a condenser microphone the currents from which are amplified and differentially added to the output of the second valve V2. The product after the necessary amplification and phase correction is added to the input of the loud-speaker to produce a correction of the disconformity between the input and output.

Abstract: 1,263,777. Spray carburettors. BENDIX CORP. May 8, 1969 [May 8, 1968], No.23476/69. Heading F1B. Air/fuel mixture supply and mixing means comprises a primary mixture conduit 22, Fig. 1, an air-flow responsive valve 16 controlling the total air-flow and connected to fuel-flow control means to vary the fuel-flow rate, a secondary conduit 24, first and second throttle valves 42, 44 associated respectively with the primary and secondary conduits and control means for the first and second throttle valves. The carburettor 10 has an air valve 16, which opens in response to increased air-flow, and primary and secondary conduits 22, 24 in which throttle valves 42, 44 are controlled so that valve 42 is nearly wide open before throttle 44 begins to open. Opening of valve 16 causes a cam 36 to act through a spring- loaded lever 34 on a needle valve 30 to control the fuel-flow to conduit 20. Conduits 22, 24 respectively connect with conduits 122, 124 in a manifold 12 and the conduit 122 passes into the conduit 124 near to the inlet passage in the cylinder head. The primary conduit 124 may be heated by the exhaust passage. Operation. Mixture is formed in conduit 22 the fuel supply being proportioned to the total airflow past valve 16. At low or idle speeds the mixture flow is controlled by throttle 42 and, since conduit 122 has a small cross-section, a high flow-rate is maintained thereby preventing fuel condensation on the conduit walls and providing proper mixing. At a predetermined point valve 44 begins to open allowing air to enter through conduit 24, the fuel supply to conduit 22 being proportionally increased.
