Abstract: 1,148,040. Sewing machines. ORDENA TRUDOVOGO KRASNOGO ZNAMENI PODOLSKY MEKHANICHESKY ZAVOD IMENI M.I. KALININA. 23 Oct., 1967, No. 48036/67. Heading D1G. In a zig zag sewing machine, a pattern cam and follower are mounted on a frame located near the free end of the upper arm of the machine, the cam receives rotary motion from the crank mechanism reciprocating the needle bar, and the needle bar receives transverse movements through a linkage of stitch-adjustment means also mounted on said frame. A frame 12 is supported, within and adjacent the free end of the upper arm of the machine, at its lower end by a spindle 24 and at its upper end by a screw passing through the slot 51 in frame 12. The needle bar is slidably carried by an upper beating 45 pivoted to frame 12 and a lower bearing 45 pivoted to the lower arm of a lever 37 pivoted intermediately on frame 12. The needle 8 may be adjusted relatively to the needle aperture in the throat, plate 52 by varying slot 51 relatively to the securing screw therein. A bush 30, journalled on spindle 24, is rigid with a ratchet wheel 26 and is releasably secured to a pattern cam 20 by a pin and notch connection 31, 32. A pitman 9 couples a crank pin on the arm shaft 3 with a pivot pin 28 on a clamp 10 rigid with needle bar 11. Pivot 28 is embraced by a slot at one end of an arm 25, the other end' of which is pivoted on spindle 24. A pawl 27 is pivoted on arm 25 and is biased by a spring 29 into engagement with 'ratchet wheel 26. Reciprocation of needle bar 11 thereby serves to impart intermittent rotation to pattern cam 20. A cam follower arm 21, pivoted at 23 to frame 12, has a nose engaging cam 20 and an opposed surface engaging a plate 38. The latter depends from and is pivoted to one arm of a lever 39 which is pivoted intermediately to frame 12 and carries on its other arm a roller (42) engaging a cam slot 41 formed in a disc pivoted on frame 12 and rotatable by means of a knob 40. A knob 22, rotatable on frame 12, is rigid with a crank 44 pivoted to a depending arm carrying a roller 43 interposed between plate 38 and the upper arm of lever 37. A spring (53) acts on the latter to bias follower 21 against cam 20. The arrangement is thereby such that on reciprocation of needle bar 11, lever 37 is oscillated to impart transverse oscillation to needle bar 11, the amplitude of said oscillation being variable by manipulation of knob 22, and the field of said oscillation being variable by manipulation of knob 40. Needle bar 11 may alternatively reciprocate in a rigid frame pivoted at its respective ends to frames 12 and lever 37. Arm 25 may alternatively be coupled to bush 30 by a train of toothed gearing.

Title: Speed Control System.
IPC: B60K31/08
Filed: 1966-11-15
Abstract: 1,170,946. Fluid pressure servomotor systems. CURTISS WRIGHT CORP. Nov. 15, 1966 [Nov. 16 1965], No.51058/66. Heading G3P. Vehicle speed is controlled by a system whereby opposing torque signals, representing actual vehicle speed and a desired speed, operate a valve member to control the application of fluid-pressure to a servomotor and thereby the position of a throttle connected with the servomotor to control speed. Actual vehicle speed is transmitted, via shaft 26 to a disc magnet 34, having a plurality of magnetic poles at its end face, and this, on account of electro-magnetic drag, tends to produce a similar rotation of disc 46, of copper or other similar material, spaced therefrom and rotatably mounted through bearings 52 on a shaft 50. A preload torsion spring 56 has an end 58 secured to the disc 46 and the other end 59 to a normally fixed plate 60, so that up to a predetermined low speed the spring prevents the plate 46 from rotating. Above this speed the disc experiences a torque proportioned to this speed and transmits this, by means of a rod 62 fixed to it, to a drive wheel 116 attached to one end of the shaft 50, this torque being opposed by a speed setting spring 118. The resultant torque on the shaft 50 is transmitted to the movable valve closure member 78 within a rotary valve 74. If the vehicle speed exceeds the predetermined low value but less than the desired speed, as determined by the load on spring 118 then the torque due to this spring is greater than that due to the disc 46 and so member 78 is caused to move and so substantially close port 80, which communicates with atmosphere, and open port 82, which communicates with a valve 88 and engine manifold I. Pressure within chamber 76, and consequently bellows 18 connected to this chamber by duct 94, is lowered as a result of which the bellows contract and so opens the throttle T to increase the speed. Should this exceed the desired value, then the torques acting on shaft 50 are such that member 78 moves in the opposite direction and so, by substantially opening port 80 (atmosphere) pressure within the bellows is re-established and the throttle subsequently closed. Such automatic speed control is possible only if valve 88 is open, this being achieved only above the predetermined low speed at which switches 68 and 102 are closed so making the electric circuit which energizes a solenoid coil 148 responsible for opening the valve. Automatic control may, on account of the circuitry used, be permanently disconnected, as an opening switch 136, or temporarily disconnected, as on applying the vehicle brake, a re-setting switch 168 being provided in the case of the latter. In a modification, Fig. 3, (not shown), a clutch mechanism (172) is interposed between members 116 and 78, the arrangement being such that the desired operating speed of the vehicle may be changed while it is in motion. The speed control means described may equally well be applied to a rotating shaft within a stationary system e.g. a generator or engine.

Abstract: 1,159,320. Digital transmission systems. PATELHOLD PATENTVERWERTUNGS- & ELEKTROHOLDING A.G. 24 Nov., 1966 [26 Nov., 1965], No. 52573/66. Heading H4P. In an arrangement for synchronizing two feed-back pulse-train generators, the outputs of both generators are passed to a modulo-2 adder P 10  which feeds a unit providing an output which controls one of the generators. Each generator comprises a shift-register with a modulo-2 adder, unit A, with a feed-back loop as shown. When the generators are to be synchronized, the output e 0  of one generator is transmitted to the other, where it arrives as e 1 . By reversal of S 1 , sufficient pulses are passed to the register in A 1  to fill it. When S 1  returns to rest the output e 11  of A, passes to P 10 , unit K having no effect. The resultant, e 2 , is negative if there is lack of sync. or if e 1  contains a noise pulse. This signal e 2  is passed direct and via a unit B 1  identical to A 0 , A 1  to AND gate T 1 . If the gate gives a negative output it is assumed that the generators are not in sync. and unit K is caused to invert the signal in the feed-back loop. The use of the unit B 1  and gate T 1  ensures that a noise pulse does not cause K to be operated. To prevent noise, fortuitously spaced by the duration of the delay, from operating K the circuit is modified, Fig. 3 (not shown), by the provision of a plurality of stages identical to unit B 1  and gate T 1  in cascade. By use of a programmed switching arrangement an equivalent circuit is obtained which uses only one such stage, Fig. 4 (not shown). If the noise pulse rate is excessive or if no signals e 1  are obtained the control input to unit K is inhibited.
