Title: Method and apparatus for the control of the bobbin formation in speed frames
IPC: D01H1/36
Filed: 1964-08-04
Abstract: 1,077,651. Builder motion. ZINSER TEXTILMASCHINEN G.m.b.H. Aug. 4, 1964 [July 19, 1963], No. 30537/64. Heading DID. In a speed frame builder motion the reversing of each lay is effected according to a template. In Fig. 5 the template is formed by arms 23, 24 which are carried on a carriage 26 and alternately engaged by a feeler 18 which reciprocates with the bobbin rail 14. As rail 14 approaches the end of a lay the feeler 18 engages the arm 23 or 24 and thus shifts the carriage 26 so that a cam 27 or 28 closes a switch 29 or 30; the closing of either switch causes, by means of a gear box 17, the drive to the bobbin rail rack 16 to be reversed; a step by step mechanism 34 is also actuated to turn a spindle 19 through a fixed angle and move the feeler 18 at right angles to the direction of traverse of the bobbin rail, via a threaded portion 20 on the spindle 19 so that the gradual shortening of the lay is effected. In addition spindle 19 adjusts a variable speed gear 10 to adjust the spindle drive. In Fig. 7 not shown the carriage (26) is split into two portions; in Fig. 8 not shown two feelers are provided on the carriage (26) while feeler 18 is replaced by a template moving with the spindle rail; in Fig. 9 not shown a single feeler is provided on carriage (26) which is alternately engaged by the opposite sides of an internal cam moving with the spindle rail. In other forms the arms 23, 24 are replaced by rods whose inclination and spacing may be adjusted; the rods may be curved. In a further form the arms 23, 24 are replaced by flexible bands of synthetic material or metal which have multiple mounting points so that their contours may be adjusted. To adjust the length of the bobbin the transmission of motion between spindle rail 14 and feeler 18 may be other than 1:1, or the opposed arms 23, 24 may be relatively moveable or the feeler 18 may be arranged to have an adjustable length.

Title: Improvements in or relating to speed governors for toy vehicles and the like
IPC: A63H29/04
Filed: 1950-12-15
Abstract: 685,258. Toy railways. HUCK, H., [trading as BUB, K.]. Dec. 15, 1950. [Jan. 31, 1950; March 24, 1950; April 28, 1950] No. 30623/50. Class 132 (iii). [Also in Groups XXVI and XXXIV] Speed governing apparatus for spring motor driven toys comprises a driven disc 3, Figs. 5, 6, having U-shape strips 5 swingably inserted in slots 4. A disc 7, Fig. 3, has an aperture with a flange 8 against which the strips 5 drag when the disc 3 is rotated by the mechanism to be controlled. The governor is adjusted by moving the disc 7 axially of the driving shaft of the disc 2 and thus varying the amount by which the strips 5 are forced back out of their expanded position caused by centrifugal force. The axial movement of the disc may be effected by a screw thread control or by the engagement of an oblique edged member or slot with a lever attached to the disc 7. As shown in Figs. 11, 13, a deflector 111 on a movable cross bar 112 of a rail track may be made to engage a detent arm 108 of which a lug 106 is displaceable on a spindle 107 of a track vehicle mechanism. The triangular shape of the deflector 111 enables the device to operate with the vehicle approaching from either direction and in combination with a deflector facing in the opposite direction, Fig. 14 (not shown), provides both speed increase and speed decrease control. Varying the lateral position of the bar 112 controls the amount of speed control. Modifications comprise governor control by (a) star wheel and track stirrup, (b) friction wheels engaging auxiliary rails, and (c) a spring balanced control which is adjusted in accordance with the tractive force exerted at the coupling of a locomotive and its load. The latter control may be adapted, e.g., to toy crane drives.

Filed: 1946-10-16
Abstract: 617,688. Root crop harvester. LAPIERRE, R. A. Oct. 16. 1946, Nos. 30816, 30817 and 30818. Convention dates. Oct. 16, 1945, Oct. 16, 1945 and Oct. 30, 1945. [Class 6 (iii)] [Also in Group XXX] A root crop harvesting machine comprises the combination of a lifting device, a first longitudinal chain conveyer followed by a second such conveyer which rotates at a higher speed than the former, a transverse chain conveyer with a deflector, and a platform having a moving apron the platform being adapted to occupy three directional positions so that crops lifted in succession from three adjacent rows are deposited in a single row. In the construction shown, a pair of cutting discs 15 flank the lifting plough 10 whereby a strip of soil is cut out and passes to the conveyer 16 thence to the conveyer 31, which passes the crops to the conveyer 40 and finally to the apron 60. A motor M drives all the moving parts, through a driving wheel 23 and associated mechanism. The deflector 41 functions to spread out the crops on the conveyer 40 which passes them to the apron 60. Referring to Fig. 2, the platform has two side cheeks 67, 67<SP>1</SP>, which are pivoted on the axis 65, 65<SP>1</SP> and actuated by a connecting rod 70 which is pivoted to a lever working in a quadrant whereby the three working and one transport positions can be attained and retained, said positions being illustrated in Figs. 3 to 6 (not shown). When the first two rows are being treated the apron moves in the opposite direction to the transverse conveyer, whereas for the third row it moves in the same direction. In order to effect this reversal. the mechanism employed comprises a pair of pinions mounted on a pivotal support so that one or the other meshes with a driving pinion 64. The driving roller of the apron is operativeiy connected to one of the said pinions which when it is directly driven by the pinion 64 moves the apron towards the conveyer 40 ; whilst if this same pinion is indirectly driven through the second pinion, the direction is reversed. The movement of the second pinion into mesh with the driving pinion is brought about by a cam surface engaging a roller on its shaft. In a modification, Figs. 9 - 12 (not shown) the apron moves in the same direction for all three rows and is arranged at right angles to the transverse conveyer 40. In this construction a movable deflector is used. When harvesting artichokes, a central cutting disc 9 is employed.

Title: Overload protection circuit for high impedance amplifiers
IPC: H03F1/52
Filed: 1963-08-08
Abstract: 1,049,676. Protecting transistor amplifiers. ADAGE Inc. Aug. 8, 1963 [Aug. 21, 1962], No. 31419/63. Heading H3T. To protect an amplifier against input overload and output short-circuit a non-linear impedance is connected in series with the input terminals and a signal indicating overload and output short-circuit causes a voltage source to be connected between the input terminals. The Figure shows a direct current amplifier 10 of the kind described in Specification 1,002,632 having added to its input circuit a pair of diodes 30 arranged normally to have a low impedance for small signal currents but a high impedance for higher signal currents. In addition, an overload indicating signal is derived on lead 20 from the collector of the output transistor 54 which, if the current through 54 is excessive due to excessive drive or short-circuited output, causes a transistor 98 to conduct and render a diode 92 conducting so clamping the input potential. This also provides low impedance path for the input signals so that the input diodes 30 become high impedance. Similarly, if the current through 54 is too low due to excessive drive or short-circuited output, a diode 90 conducts to clamp the input potential and to provide the low input impedance path to make diodes 30 high impedance. Diodes 102 provide a small series bias voltage and diodes 94, 96 normally provide a high impedance but this is lowered when the overload occurs. Fig. 1 (not shown), illustrates a simpler alternative in which upon overload occurring switch 22 or 24 is operated to connect a source 26 or 28 between the input terminals.
