Title: Improvements in severing devices for the threads of lock stitch sewing machines
IPC: D05B65/00
Filed: 1966-08-23
Abstract: 1,142,729. Sewing machines. UNION SPECIAL MASCHINENFABRIK G.m.b.H. 23 Aug., 1966 [25 Aug., 1965; 15 July, 1966], No. 37654/66. Heading DIG. A lock stitch sewing machine is provided with thread-severing means comprising a blade which is arranged to move between the throat plate and a rotary hook over the bobbin case-retaining finger and into the path of the needle when the thread loop has been drawn out to its greatest extent, the blade remaining in this position until the cast loop has been drawn therearound, and then being moved backwards towards a fixed knife blade. As shown, a fixed bar 3 carries a finger 4 restraining the rotation of the bobbin case in a rotary hook 7. A knife blade 19, fixed to bar 3, overlies a raised surface 22 of finger 4. An arm 11, pivoted to bar 3, is biased by spring means normally to position a threadseizing blade 9, carried thereby during the final rotation of the sewing machine, under blade 19. When the rotary hook draws the seized needle thread loop to its fullest extent, arm 11 is swung by an energised solenoid to carry blade 9 over finger 4 and into the path of needle 6, whereby, when the loop is cast, the side 25 of the loop extending from the work and the bobbin thread 26 are drawn about the side of blade 9 facing blade 19, while the side 27 of the loop extending from the needle is drawn about the opposite side of blade 9. The solenoid is then de-energised, whereby blade 9 returns to its initial position and sides 25, 26 are severed, the cut ends being held between blades 9, 19. The energisation and de-energisation of the solenoid are controlled by contacts on conventional needles positioning means. In a modification, surface 22 is grooved to receive the threads drawn thereover, and arm 11 is provided with a resilient thread-controlling finger.

[Also in Division E1] An hydraulic jack arrangement used as a pit prop comprises an outer part 1 with an inner part 2 provided with a piston 13 and a return spring 15. Hydraulic fluid can enter or leave the prop through a passage 16. The prop is provided with a pneumatic stroke-measuring device comprising a scale in the form of a rotatable disc 17 in a space defined by matching recesses in base 19 of the part 1 and a cylinder cover 20. The disc 17 is carried on a spindle 18 mounted on a thrust bearing 5 and has an upper threaded section screwed through a nut 4 attached to the piston 13. The disc 17 contains small holes 12 through which pairs of passages 8, 9; 10, 11; &c. can communicate with one another, the lower passages 9, 11 being supply passages for compressed air, the upper passages 8, 10 being exit passages. A continuous flow of compressed air exits from passages 8, 10. If a hole 12, Fig. 2, is in line with passages 8, 9 then a substantial laminar flow is created by which energy is transferred and a control circuit (not shown) actuated. If the hole 12 is not so located then a turbulent state is created and no signal developed. In dependence on the particular piston positions binary signals are generated which can be processed in various ways in a control system, e.g. to indicate the piston position.

Filed: 1969-08-01
Abstract: 1,208,100. Automatic exchange systems. SIEMENS A.G. 1 Aug., 1969 [2 Aug., 1968], No. 38593/69. Heading H4K. Should a junction to a satellite exchange be held as the result of a false response or a fault at the satellite, forced release is effected from the main exchange by charging a capacitor in shunt across the junction at the satellite so that discharge of the capacitor effects loop disconnection and diversion of the junction to the satellite control circuit, the time constant of the capacitor charging circuit being sufficiently high to prevent operation of the circuit in response to ringing. As shown in Fig. 1 a subscriber Tn at the satellite with network KE is accessible over a junction HL from a main exchange Vst, the junction being terminated at the satellite on a circuit BS that can effect forced release and diversion to control circuit ES in receipt of switching instructions over one or other of the junctions such as HL. If the junction is held by low impedance, either presented from a subscriber or by a fault which loops the line, main exchange Vst effects release by connecting earth at f1 so that shunt capacitor C1 charges at BS to the small residual voltage across the loop. When charged, f1 is released and C1 discharges with transistor T1 providing a discharge path through relay A a contact of which breaks the loop. With the loop broken a positive potential is applied from f2 at Vst to charge a shunt capacitor C2, charging of which up to this time is prevented by Zener diode 8. With f2 broken, discharge of C2 operates relays A, B and C, in series to complete diversion to control ES and release the network KE. An alternative arrangement, Fig. 2, not shown, places all three relays A, B and C under control of the discharge current, of capacitor C2, a fourth relay (H) effecting disconnection of the loop in response to discharge of capacitor C1. By this means the diversion contacts a, b can be positioned at the satellite side of circuit BS and earth pulsing of one leg is sufficient to effect control if operation of relay (H) diverts the leg to an otherwise disconnected shunt capacitor C2.
