Abstract: 1,230,691. Electro-hydraulic servosystems. MESSERSCHMITT-BOLKOW-BLOHM G.m.b.H. May 13, 1969 [May 27, 1968; Jan.30, 1969], No.24294/69. Heading G3P. In a triple channel control system for aircraft, the outputs of jet tubes 50 driven by torque motors 51 are summed by rotary spool valve 19 which controls servopiston 14; feedback provision at 15-18 and 52 ensures that the servopiston will only be displaced a small amount in the event of failure of one channel. The outputs of the jet tubes are fed in pairs of similar sign to double acting comparators 21-23 connected in parallel to a line 38 supplied via restrictor 42 and in series to a line 44 supplied via restrictor 47 and a chamber at the right of a spool 20 which inter-connects opposite sides of the servopiston upon rightward movement. Failure of one channel as sensed by the comparators is signalled at 43, and failure of two or all channels is signalled at 49. The servopiston is centred by spring-loaded pistons 55 upon rightward movement of spool 20 following venting of line 44 or loss of supply pressure. The spool 20 also closes supply line 24 and vents line 44 at 54 to prevent repressurization of line 44 otherwise than by actuation of auxiliary valve 56. In the modification of Fig. 2 (not shown), duplicate pressurized fluid supplies are provided and the servomotor has tandem pistons. In Fig. 3, (not shown), two jet tubes are biased to opposite sides of their null positions when their torque motors are unenergized. The feedback in these two channels is trimmed to compensate for this bias. Schmitt triggers provide overload protection for the torque motors. In each case, the jet tubes could be replaced by flappers.

Abstract: 1,250,415. Sewing machines. UNION SPECIAL MACHINE CO. 7 Feb., 1969 [21 Feb., 1968], No. 6626/69. Heading D1G. A feed mechanism for a sewing machine comprises a feed bar carrying a feed dog, means for reciprocating the feed bar, slide members or blocks at opposite ends of the feed bar for sliding movement therein parallel to the feed direction and eccentric means operatively connected to the slide members in order to provide lifting and lowering motion in the feed bar.  As shown in Figs. I and 5 the lift for the rear of the feed bar is produced from an eccentric mounted on the main shaft 22 which through suitable links and cranks produces vertical lift of a block 85 whereas the vertical lift of the front end is produced by an eccentric end 87 of the main shaft acting on a block 84. The blocks 84, 85 are horizontally moveable in the feed bar 70. Horizontal movement for feed is produced by a pitman 110 acting on a pin 111 fastened to the feed arm and which is driven from a further eccentric 105 which eccentric is replaceable to vary the feed stroke. In Fig. 13 a second shaft 133 is provided and driven at a 1:1 ratio from the main shaft. An eccentric 132 at the end of this shaft produces lift via a block 131 similar to the eccentric 87 on main shaft 22. The relative rotation of these shafts produces a feed which will bunch or stretch the fabric. The pitman 111 driven by eccentric 105 can derive its motion from either shaft to produce feeding motion. For another embodiment (Fig. 16 shown as an exploded view) eccentric 226 produces vertical motion through blocks 222, 223 and horizontal motion through a block 225. Vertical motion of the rear end of the feed bar is produced by a block 208. In this case two feed dogs are provided in slots 194, 195. A thread cutter having a fixed blade 60 and a movable blade 61 is provided the movement for this being provided from the main shaft 22 of the machine through a shaft 64. A looper is driven in a generally eliptical path through an eccentric assembly 37 which through a pitman and lever rocks the looper rock shaft to provide the needle avoid movement and from a lever crank assembly 36 through a pitman 38 and ball stud 40, lever rock shaft 47 and driven lever 40 to provide the oscillating motion.

Abstract: 1,250,655. Burner controls. HONEYWELL Inc. 14 Nov., 1968 [22 Nov., 1967], No. 54143/68. Heading F4T.  In a burner control apparatus for controlling the ignition sequence and the main supply of fuel to a burner including a prepurge timer 18, the timing means includes an unijunction transistor 44 or two or more transistors having the same input/output characteristics, a capacitor 48 connected to apply a voltage to the input of the unijunction transistor and normally receive a charge during the purge period through an impedance and current responsive means in the form of a relay IR controlling contacts which establish the trial period by being closed, connected in the output of the unijunction transistor, the capacitor 48 being also connected in the output of a transistor 42 the input of which receives a signal from a flame detector circuit 20 which causes the transistor to shortcircuit the capacitor 48 through a diode 54 and which is indicative of a flame at the burner. In operation a switch 17 is closed to energize a transformer 29 and a rectifier 32 charges capacitor 33 and energizes a relay 3R via a lockout switch heater 23 and relay IR to complete a holding circuit and energize air flow motor 11, the air flow switch 16 responding to air flow to energize the timer 18 so that charging of capacitor 48 begins and after a time delay transistor 44 becomes conductive and the capacitor 48 discharges through the coil 19 of relay IR to complete a maintaining circuit and energize heater 23. Closing of contacts IR4 energizes pilot valve 12 and igniter 13 to institute a trialfor-pilot-flame period, a lock-out switch 22 being operated by heater 23 if the pilot flame is not established. Establishment of flame causes transistors 41, 42, 43 to become conductive, flame relay 2R causing the heater 23 to be deenergized and the circuit to capacitor 48 and transistor 44 to be opened. Flame failure during operation causes transistor 40 to be rendered conductive to render transistors 41, 42, 43 non- conductive and de-energize relays 1R, 2R to shut down the burner.

A non-woven fabric comprising 10 to 89% continuous polypropylene filaments and 11 to 90% polypropylene core-nylon 6/6À6 sheath bicomponent filaments is bonded by treating with saturated pressurized steam. A screw extruder supplies molten polypropylene to the central chamber 7 of a spinneret, from which it emerges as homofilaments via orifices 3 and as the core of bicomponent filaments through orifices 4. A second screw extruder supplies a mixture of molten polyhexamethylene adipamide (nylon 6À6), 65 to 95% by weight, and polyepsiloncaprolactam (nylon 6) to outer chamber 9, from which it is extruded as the sheath, the core/sheath ratio being 60/40. The polypropylene filaments and cores have a birefringence of at least 50% of the possible maximum. Each spinneret produces 40 mono and 42 bicomponent filaments of equal decitex. The filaments are quenched in air, brought into a yarn structure and drawn 2À71 to 3 fold between pairs of rotating rolls. Eight yarns are electrostatically charged and led through transversely reciprocating air jets on to a moving wire mesh belt to form a web. The web is bonded in a steam chamber and compressed by the chamber's inlet and outlet seal, and sprayed with a non-toxic polyethanoxy surfactant oil. In one embodiment the web is tufted with 3 tufts 1 cm along the length and 2À2 tufts 1 cm across the width using 2720 dtex nylon yarn. The fabric may be laminated with one or two layers of paper, using bitumen as adhesive.
