Title: Electrical oscillation generator
IPC: H03K4/12
Filed: 1951-12-17
Abstract: 722,430. Electrophonic musical instruments. HILLS, L. J., and JENNINGS MUSICAL INSTRUMENTS, Ltd. Dec. 16, 1952.[Dec. 17, 1951; May 9, 1952], Nos. 29518/51 and 11826/52. Class 88 (2) [Also in Group XL (c)] In an oscillator comprising two cathode-coupled valves a, b (see Group XL(c)), in which the notes are selected by closing contacts to include discharge resistors 1, 2 3, fine tuning is accomplished by varying the current through the second valve b. By this means the tuning of the instrument may be varied without affecting the relationship of the individual notes. This may be achieved by the use of a variable resistor 11 or by altering the bias of valve b. During the fly-back, the capacitor 4 is charged through valve a, the current flowing in resistor 5 maintaining valve b cut off and hence the anode at high potential so that the grid of valve a is driven positive. When the charging rate falls, valve b conducts, thus, cutting off valve a. Capacitor 4 discharges over a selected resistor 1, 2 or 3 to generate the forward stroke of the sawtooth, the flow of current through resistor 5 maintaining valve b conducting. The output is fed over a shaping circuit including a diode c and the pulses occurring at the anode and cathode of valve b may be added by operation of switches 20, 21. Tone control networks may follow the shaping circuit. The generator may be periodically switched off and on by a multivibrator d, e to give the effect of a banjo or mandoline. By using a smaller amplitude, a vibrato effect may be obtained; Fig. 5, the output varying the standing bias on the main oscillator valves a, b of a polyphonic instrument. Each oscillator may give one of two notes separated by a semitone.

Title: Improvements in or relating to printers or punchers
Filed: 1962-08-01
Abstract: 1,016,712. Selective printing. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 1, 1962 [Aug. 2, 1961], No. 29556/62. Heading B6F. Type - wheel machines ; hammer impression arrangements.-A selective printer having a single continuously rotating type carrier 5 is provided with a hammer mechanism comprising a firing pin 2 supported on leaf-springs 13, 14 and a hammer 1, latched by an electromagnet 25 in its rest position and urged into an operative position by a spring 21 on de-energization of said electromagnet to impel longitudinally said pin 2, which impacts a record tape 3 against a selected type character 4 on the type carrier 5. The released hammer is arrested by a stop 32 whilst the pin 2 which effected the impression under momentum is arrested by a stop 16 on rebound, any oscillation being quickly damped by a plunger and spring arrangement mounted internally of said pin (Fig. 3, not shown). The hammer 1 is restored by an arm 34, which is released by an electromagnet 44 when the high point of a restoring cam 10 is nearest to it, whereupon a spring 39 moves the arm 34 upwardly in timed relationship with the rotation of cam 10 to move the hammer from a position abutting said stop 32 to a position adjacent pole faces 29 and 30 of the electromagnet 25, which is then re-energized to re-latch the hammer. Paper, strip feeding, guiding and tensioning arrangements; positive letter-spacing arrangements.-The record strip 3 is fed from a feed reel 57 over guide 60, 61 and deflected about a continuously rotating capstan 58, the incremental advancing of the tape being effected by a foot 51 and pawl 52 arranged at the distal end of a lever 38 integral with the oscillating restoring arm 34. When the arm 34 moves counterclockwise the pawl 52 moves away from the foot 51, thus unclamping the tape 3, which, however, is prevented from reverse movement by a second pawl 54 biased towards a guide pin 56 by a spring 55. As the arm 34 subsequently moves in a clockwise direction the tape is clamped against the foot 51 by a wedging action produced by the pawl 52 and the tape is moved a distance from right to left. The tape advance is assisted by a tensioning member 63, which when sufficiently deflected increases the force on the capstan 58, the latter advancing the tape a small increment. Roller inking arrangements.-An inking roller 11 mounted on a shaft 12 bears against the type carrier 5 and continuously replenishes the ink on characters 4. The roller has an internal ink reservoir and the ink is conveyed from the reservoir to the type carrier through a porous wall. Power for rotation of the inking roller 11 is supplied through the frictional engagement of the roller with the type carrier 5.

Title: Yarn feeding device
IPC: D02G1/02
Filed: 1973-06-22
Abstract: 1428496 Yarn feeding; belt and roller arrangement CHAVANOZ SA 22 June 1973 [26 June 1972] 29795/73 Heading DID A yarn feeding device for textile machines, particularly false twist texturising machines, comprises a rotating drum 1 and an endless belt 3 which in the operational position is applied against the drum over a first arc (Figure 3), the yarn 10 passing between the belt and the drum, and the belt 3 being mounted on two idling rollers 4, 5 carried by a support arm 8 for movement between the operational position and a non-operational position in which the belt 3 is out of contact with the drum 1, the support arm 8 having means pretensioning and maintaining the belt in an intermediate position between the operational and non-operational positions (Figure 2), the belt in this intermediate position being in contactwiththedrum over a second smaller arc and at a pressure lower than those utilised in the operational position. The positioning means comprise an adjustable abutment 13 mounted on an arm 14 pivoted about axis 17 fixed relative to the pivot 9 of the support arm 8. In the intermediate position i.e. at the start-up of the machine, the abutment 13 presses the belt 3 against an arc of the drum 1. Also in the intermediate position, the pretensioning means e.g. roller 15 mounted on arm 16 pivoted at 17. acts on the belt 3 to provide the required tension in the belt. The force exerted by the belt on the drum is adjusted so that the forwarding force exerted on the yarn 10 is less than the breaking tension of the yarn. The positioning means 13 and pretensioning means 15 are acted upon by springs 18, 20 so that when the support arm 8 moves to the operative position (Figure 3) the positioning means and pretensioning means are moved to an inoperative position. In a further embodiment, the pretensioning means acts to vary the distance between the axes of the idling rollers in response to movement of the positioning means between operative and inoperative positions.

Patent GB-365145-A (GB)
Title: Improvements in or relating to coupling devices for tractor-trailers
IPC: B62D53/08
Filed: 1930-10-07
Abstract: 365,145. Tractor -trailer couplings. KARRIER MOTORS, Ltd., CLAYTON, R. F., AVERNS, R. DEAN-, and MEEK, P., St. Thomas' Road, Huddersfield. Oct. 7, 1930, No. 29968. [Class 79 (iii).] A tractor-trailer coupling device comprises an arrangement whereby after the front wheels of the trailer have been raised from the ground by backing the tractor under the front end of the trailer and the tractive connection effected, such connection, under the forward pull of the tractor, causes the trailer front wheels to be swung in a forward and upward direction, a catch preferably being provided to maintain the wheels in such position. In coupling the vehicles, rollers c on a shaft d mounted in bearing supports e on the usual trailer turntable f ride up ramps b on the rear end of the tractor frame a thereby raising - slightly the trailer front wheels g which are carried by depending arms h on the shaft d. Also secured to the shaft d near the ends thereof are two pairs of arms h<1> carrying at their lower ends rollers i or a cross-bar adapted to be engaged by coupling hooks k<1> carried by a transverse shaft k mounted in brackets j on the tractor frame, the shaft k being rocked to raise or lower the hooks by a hand-wheel m<3> acting on a screwed rod m<2> coupled by a link m<1> to an arm m on the shaft. Prior to coupling, the arms h carrying the wheels g are rigidly connected to the turntable, the shaft d being, for this purpose, provided with an arm n3 adapted to be locked to a bracket s by a bolt t. In the coupling position, Fig. 3, in which the rollers c abut against the upturned ends b<2> of the ramp b, the hooks k<1> are brought down to engage the rollers i and the bolt t is withdrawn. Thereupon, the initial tractive effort on the rollers i rocks the shaft c swinging the trailer front wheels in a forward and upward direction, Fig. 1. As the shaft c rocks, the arm n<3> thereon, released from the bracket s, is engaged by a hooked catch n<1> pivoted on a bracket n on the ramp and pulled by a spring p, a tie rod u passing loosely through a bracket v acting as a stop. Release of the catch may be effected from the driver's seat through a coupling rod o. The Provisional Specification describes somewhat different constructional arrangements wherein the arms or levers carrying the front wheels of the trailer, whilst being mounted at their upper ends on the transverse shaft carried by the turntable, are connected between their ends by a second transverse shaft adapted to be engaged by the coupling hooks, the connections of the levers to one of such transverse shafts being by means of curved or angular slots. A prop member or members with or without springs carried by the second transverse shaft bears against the turntable to limit the movements and means are provided to lock the members when the wheels are elevated. It is also stated that the brake-actuating mechanisms of tractor and trailer may be automatically connected when the coupling connection is effected.
