Abstract: 141,476. Wilcock, Wood, & Co., Ogden, I., and Watson, J. C. March 11, 1919. Stop-motions.-A wellknown form of stop mechanism, which acts by bearing on the fabric to detect faults therein, is adapted to be placed temporarily out of action while passing over one or more mis-stitch wales or seams which may form cutter-guiding indications to indicate subsequent division of the web. The detector mechanism comprises a spring-pressed finger 10 mounted in an arm 5 secured to a vertical shaft 2 supported in bearings 3. When the finger 10 enters a faulty place, the movement of the needle cylinder 12 swings the arm 5 aside against the action of a spring 4, and allows a lever 8, normally retained in position by a projection 7 on the shaft 2, to be tripped to stop the machine. To place the detector mechanism out of action while passing mis-stitch wales which would otherwise stop the machine at each revolution, the finger 10 is provided with a depending portion 14 to engage cams 15 placed on a moving part 6 at the points corresponding to the position of the mis-stitch wales it is desired to produce. Should a long horizontal defect occur such as might not cause the finger 10 to act at once, an adjustable piece 16 is brought, by the spring 13 against the needle cylinder 12 to swing the arm 5 aside and stop the machine.

Abstract: 1507773 Handle for powered percussion tool ATLAS COPCO AB 17 Feb 1976 [18 Feb 1975] 06191/76 Heading B4C  A handle for a percussive tool comprises a handgrip for applying pressure to the tool so as to force it against a workpiece, the handgrip including a first portion 15 and a second, wing-shaped, portion 16 which when the tool is in use projects towards the operator, the upper side of the wing-shaped portion providing a support for the palm of the operator's hand and thereby forming the main pressure surface. Preferably a handle is provided for each hand and the tool is powered by compressed air. Portion 15 is cylindrical and adapted to be clasped by the thumb and forefinger. The second portion 16 has an edge 17 facing the tool which co-operates with the operator's thumb to limit outward movement of the hand along the hand-grip. Portion 16 is inclined to the axis of cylindrical portion 15 so that edge 17 is nearer the workpiece. Its top surface is concave at least at edge 17 and the opposite edge and preferably along its whole width so that the pressure on the middle of the palm is minimized.  In the embodiment of Fig. 15 the handle 11 is turnable about a shaft 25 to facilitate lifting the tool, shaft 25 having opposed abutments 29, 30 which co-operate with lugs 26, 27 on the hand to define the use position shown and a lift position biased by spring 28. The supply of compressed air is controlled by turning the handle. In the lift position, Fig. 16, there is no connection between channel 31 which communicates with an air manifold and channel 32 which communicates with the hammer. Communication is established in the use position of the handle (Fig. 17, not shown) via recess 33 and transverse channels 34, 35. The handle may be mounted resiliently on the tool by means of a torsion bar (37, Fig. 11, not shown).

Title: Electrical pulse signal generator
Inventor: GUNSTEIN DAVID ELIAS
IPC: H03K5/04
Filed: 1950-03-13
Abstract: 672,058. Pulse modulation; pulse delaying circuits; radiolocation. PHILCO CORPORATION. March 13, 1950, No. 6239/50. Classes 40 (v), 40 (vi) and 40 (vii). Duration modulated pulses are initiated by regularly spaced pulses and terminated by variably-delayed pulses, the delay being controlled by the signal voltage. The'signal may be a randomly varying voltage, as in the circuit described, the resulting pulses being used in radar systems to minimize the effects of hostile countermeasures. The pulses 18 from generator 19 are differentiated by circuit 20, 21 to produce spaced leading and trailing edge pulses 22, the negative ones being passed by diode 23 to amplifier 25. The output pulses are differentiated by inductance 26 to give closely-spaced positive and negative pulses 27, the positive ones being used to cause the series-connected triodes 29, 30 to conduct. The random modulating signal comprising the noise from an anode current saturated valve 98 is applied through amplifier 99 to the anode of valve 29 so that, when valves 29, 30 are rendered conducting, the condenser 31 connected to their junction assumes a charge proportional to the amplitude of the signal at this time, and retains it until the occurrence of the next positive pulse 27. The immediately following negative pulse 27 is fed through diode 47 to a trigger pair 48, 49 to render valve 48 non-conducting and valve 49 conducting. The resulting negative pulse at the anode of valve 49 is fed over conductor 50 to a variable delay line 32 ... 39, 41 ... 44, the output pulse from which is inverted in valve 51 and fed through diode 100 to the grid of valve 48. The latter is thereby rendered conducting again and valve 49 rendered non-conducting to terminate the duration-modulated pulse at its anode which is taken from conductor 53. The delay line, which is of the type described in U.S.A. Specification 2,506,329, comprises valves 36 ... 39 acting as series resistances, valves 32 ... 35 acting as shunt resistances, and shunt condensers 41 ... 44. Its delay is controlled by the potential of the modulator condenser 31 which is connected to the grids of valves 32 ... 35, and thus controls their impedance.

Planes, construction of.-An aeroplane with collapsible wings has the wing spars formed as lazy-tongs linkages working in a vertical plane, the wings being extended or contracted by a vertically-sliding bracket connected to the inner ends of the appropriate series of links. Figs. 1 and 1<a> show a wing having each spar composed of parallel pairs of links 1, 2 connected together. The end of the innermost pair of links 2 is pivoted to the fuselage and that of the innermost pair 1 is connected to a bracket 6 slidable on a rod 5 and capable of being fixed in position. Ribs 4 are connected to the upper series of pivots or to the distance-pieces which separate the links, and the wing is covered with fabric. When the wing is fully extended, the links 1, 2 do not come into alinement so that the system is capable of resisting transverse stresses. Figs. 3 and 4 show a modification in which each wing- spar comprises crossed links 1, 2, 1<a>, 2<a>, 1<b>, 2<b> pivoted as shown and adapted to come into alinement when the wing is fully extended. The ends of the links 1<a>, 2<a>, 1<b>, 2<b> are extended beyond their pivots and provided with lateral lugs 1<d> which engage the adjacent links when the wing is fully extended and prevent further angular movement in one direction. The inner ends of the links of the two spars in each wing are connected together and to a bracket 6 movable on a rod 5 by means of cables 16 and a winch 15, and the ends of the links 2 are pivoted to fixed brackets 11. The ribs and plane coverings are in sections, the central sections 12 of the ribs being connected to the links 1, 1<a>, 1<b> as shown in Fig. 4 and the front and rear sections 12<a>, 12<b> are secured to the links 2, 2<a>, 2<b>, so that as the links are folded the plane sections move angularly in opposite directions. The front and rear ends of the rib sections 12<a>, 12<b> are connected respectively by bars 13, 14. As applied to a biplane, the inter. plane struts 8 are pivoted to the crossing points of the links and the bracing 9 is connected to plates 10 pivoted at the same points.

Abstract: 1283662 Momentum power-storing apparatus WESTERN GEAR CORP 11 March 1971 6593/71 Heading F2X An inertia mechanism connectable in use to a dynamometer in which energy is transmitted through a rotating shaft to a test stand, comprises a pair of rotatably supported shafts 5, 6, a gear train 2, 3, 4 connecting the shafts, a motor 1 for rotating the shafts through the gear train, means for connecting one of the shafts to a device in a test stand A, B, C or D, inertia elements 10 to 14 and 15 to 19 associated with the shafts 5, 6 respectively, and means for connecting and disconnecting at least one of the inertia elements relative to its respective shaft for varying the total inertia of the mechanism. As shown, each inertia element is provided with a clutch 21 which permits any combination of the elements to be finally but releasably connected to the shafts on which they are mounted. Bearings 22 are provided at spaced intervals for rotatably supporting the shafts. If, for example, it is desired to test the effect of a predetermined amount of energy on an automobile or aircraft brake such as indicated at 25 in test stand D it is merely necessary to connect the shaft 6 by means of a clutch 26 with a shaft 27 on which the brake 25 is supported. One of the inertia elements may be replaced by a variable inertia element (Fig. 3, not shown) operating on the same principle as an inertia governor. The mechanism is then able to provide an infinitely variable inertia as opposed to a stepped variation in inertia. Motor 1 is driven at a speed greater than the speed of rotation desired and the entire system permitted to rotate with the motor cut off. As the speed slows down the connection to the device to be tested, such as the brake 25, may be made exactly when a tachometer (not shown) indicates that the speed is the predetermined speed desired.
