Title: A pulse generator
Inventor: APPLE JOSEPH SUMNER
IPC: H03K3/45
Filed: 1962-12-07
Abstract: 995,167. Transistor pulse circuits; circuits employing non-linear reactors. THOMPSON RAMO WOOLDRIDGE Inc. Dec. 7, 1962, No. 46348/62. Headings H3B and H3T. In a variable-duration pulse generator, a saturable transformer 100 is saturated in one direction by current in winding 32 and is driven into saturation in the other direction by each input voltage pulse applied to winding 7 by transistor 4. The duration of each output pulse induced in winding 25 is dependent on the time taken for transistor 4 to build up current in winding 7 sufficient to saturate the transformer 100. The duration is thus adjustable by variable resistor 35. The pulse from winding 25 is preferably inverted by the NPN transistor 27 and coupled by transformer 29 to a PNP transistor 38 having an output transformer 110. A blocking oscillator transistor 59, triggered by the offset of the waveform from transistor 27, provides bootstrap feedback to transistor 38 and hence reduces the fall time of the output pulse by minimizing the effect of carrier storage in transistor 38. The core of transistor 100 is preferably reset after each pulse by pulsing transistor 12 with a square wave antiphased to that at terminal 1.

IPC: H01H53/00
Filed: 1963-11-25
Abstract: 1,057,730. Electromagnetic relays; control of D.C. motors. SECRETARY ARMY, UNITED STATES OF AMERICA. Nov. 25, 1963, No. 46447/63. Headings H2B and H2J. A moving coil relay 6 is designed to maintain constant the direction of current in the field winding of a series wound motor despite reversal of the direction of the current in the armature winding of the motor. The relay 6 comprises a moving coil armature 7, 10, 11 rotatable in the air-gap of a permanent magnet 8. An arm 4 carrying pairs of inter-connected brushes 3a, 3d and 3b, 3c is moved by the armature over the surface of a cylinder 1 carrying four insulated conducting segments 1a, 1b, 1c, 1d, between two positions. In one position brushes 3a, 3d bridge segments 1a, 1d and brushes 3b, 3c bridge segments 1b 1c and in the other position segments 1c, 1d and 1a, 1b are bridged. A generator 14 is connected in series with armature winding 12 and field winding 13 of the motor. The relay 6 is controlled by a shunt-excited relay 19 connected in the motorgenerator circuit. Normally this relay causes energization of coil 10 of relay 6 so that contact brushes 3a, 3b, 3c and 3d occupying the full line position, but when the direction of current in the generator and motor armature winding 12 reverses, relay 19 causes energization of coil 11 and the brushes rotate to the dotted line position thus maintaining the direction of current in field-winding 13 constant. In an alternative arrangement (Fig. 4, not shown) a polarized moving coil relay 6 has only one moving coil which is energized by a shunt in the generatorarmature winding circuit so that relay 19 is unnecessary. In Fig. 2 (not shown) the relay 19 energizes or de-energizes a single moving coil which is spring-biased to one position. In Fig. 3 (not shown) the armature of relay 6 carries a continuously energized moving coil which is controlled by alternate energization of two coils wound on a fixed core in the air-gap of which the coil rotates. Sparking is prevented by capacitors shunted across the segments 1a 1b 1c, 1d. In another embodiment (Fig. 6, not shown) two coils are secured in conducting channels in the armature, the channels acting as short-circuited turns, and erratic movement of the armature is prevented by an hydraulic dash-pot. Stops limit the movement of the armature. To ensure that the armature can only come to rest in its extreme positions the armature may be spring- biased to one position or may be provided with a spring-biased detent. The brushes may be fixed and the cylinder movable.

Abstract: 1,091,028. Sewing machines. MEFINA S.A. Oct. 18. 1966 [Nov. 8, 1965], No. 46514/66. Heading D1G. A zig zag sewing machine comprises a series of cams mounted on a driving shaft, a follower carried by an oscillatory slide for selective engagement with the cams upon movement of the latter along the driving shaft, a member bearing against the slide for transmitting the oscillation thereof to the needle bar gate, an amplitude adjustment lever turnable by means of a knob thereon to vary the position of said member along the slide, said knob being carried by a spindle, rotation of which by the knob serving to shift the cams along the driving shaft. An arm 8, pivoted at 9 to a lever 10, has a longitudinal surface 7 slidably engaged by one end 6 of a connecting rod 4 pivoted at its other end to a needle bar gate 2. The length of connecting rod 4 may be varied by turning an eccentric pin 11. A spring 31 acts on gate 2 to bias end 6 against surface 7 and thereby a follower 24 on arm 8 against one of a pack of cams (25), (26), (27) slidably keyed to a driving shaft 17. An axial slot 23 at end 6 is engaged by a pin 22 on one arm 21 of a lever 20 pivoted on shaft 17. The other arm 32 journals an axially-slidable and inwardly spring biased spindle 34 which passes through a slot 36 in the machine frame 13 and carries a knob 35, manipulation of which serves to swing lever 20 for varying the position of end 6 along surface 7. An arm 56, pivoted at 55 to arm 32, engages one side of a four-sided cam 59 rigid with spindle 34, and is formed with a pair of lugs 57 engaging the lowest cam (27). A pin 43, transversely carried by spindle 34, normally engages a vertical groove 45 in arm 32, when follower 24 engages the highest cam (25) and lever 20 is turnable to engage pin 43 selectively in one of a series of notches 37 formed in a plate 38 pivoted at 39 and biased outwardly by a spring 40. If spindle 34 is turned to its leftmost position and drawn outwardly, a washer 48 fixed thereon enters a recess 51 in frame 13 to disengage pin 43 from groove 45. Spindle 34 may then be rotated axially through 90 degrees and released, when pin 43 enters a horizontal groove (46) in arm 32 and spindle 34 can be moved freely in slot 36. If spindle 34 is rotated a further 90 degrees, the third side of cam 59 raises arm 56 to engage follower 24 with the middle cam (26), and a yet further rotation of 90 degrees serves to engage follower 24 with the lowest cam 27.

The two sashes 1, e.g. of wood and 3 e.g. of metal, are held together by a hook 8 movably mounted in the frame I in a housing 9 let into the frame, as by a pin 13 on the lower end riding in a slot 14 in a slidable plate 15 moved to and fro by a screw 16, Fig. 5, the hook 8 having a projection 11 so that the hook guided between opposite walls 18, 19 of the housing is lifted from the rail 7 by movement of the plate 15 to the left, Fig. 2, and the projection 11 pivots about the end of a lug 28 on the housing wall 18 and causes the hook 8 to move outside its operative range with respect to the rail 7 and opens the connection between the two sashes. The connection is closed by the reverse operation of the hook and movement of the plate 15 to the right. In an alternative embodiment the hook 8, Fig. 22 is lifted from contact with the rail by an eccentric in the form of a crankshaft 22 rotatably mounted in the housing 9, the upper and lower faces of the eccentric, when the hook is in the closed position, being flattened, are pressed upwardly against the lower edge of the hook by leaf springs suspended from pins 33 on the hook. The lower edge of the hook is located between the pivot edge 28 and the point of engagement therewith of the leaf springs so that during the pivoting movement of the hook the springs tend to bring it to the erect vertical position. The eccentric 22 is rotated by a lever 35. Plate 15 Fig. 5, may be replaced by a crank lever connected between the end of screw 16 and pin 13.
