Abstract: 357,615. Transformers. BENEDETTO, G., 45, Via Dante Alighieri, Novara, Italy. May 28, 1930, No. 16437. [Class .38 (ii).] In a transformer comprising relatively movable windings for supplying automatically regulated current to arc-welding apparatus, the movable winding is partially counterweighted to an extent that is adjustable to enable the operating characteristic to be varied to suit different working conditions. The transformer comprises a fixed secondary 18 and a primary 19 mounted in a carrier that is slidable along angle-section guide-plates embracing the corners of a vertical core limb 28. The carrier is.suspended by flexible members 22 from arcuate guides 23 on the ends of a pair of beams 20 carried by a rocking shaft 44. The latter is geared through wheels 45, 46 to a shaft 47 carrying a beam 48 on which a counterweight 50 is slidably mounted. To provide for adjustment of the position of the counterweight during operation, it is secured to the two ends of a chain 53 passing round sprockets 51, 52 mounted on the ends of the beam 48, the sprocket 51 being coupled through a cardan joint. Fig. 3 (not shown), to a telescopic shaft 62 universally jointed at its upper end to the spindle of a hand-wheel 65 on the lid 13 of the transformer casing 11. A scale and pointer 66 together with a notched disc 67 and spring plunger 68 are provided to facilitate setting. In order that the parts may be inspected and adjusted before being enclosed in the casing 11 to the base of which the transformer is normally bolted, the latter is suspended by its upper yoke 16, on which the beams and associated mechanism are mounted, from the lid 13 by adjustable suspension members 43. The casing 11 is oil-filled and provided with wheels 12 to facilitate movement. Primary and secondary terminals 69, 70 are mounted on the lid. In an alternative construction, Fig. 4, the movable winding 92 is partially counterbalanced by floats 95 below the oil level, and the degree of counterbalancing is varied by placing weights 99 on a scale pan 97 supported above the winding 92 on rods 96 passing slidably through the lid 82 of the casing. A corrugated rubber disc 94 is placed over the fixed winding 93 to reduce shock when the winding 92 falls under open circuit conditions. Specification 340,215, [Group XXII], is referred to.

Title: Rotor and stabilising mechanism, especially for helicopters
Inventor: LAUFER THEODORE
IPC: B64C27/30
Filed: 1954-06-03
Abstract: 754,033. Helicopters. SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES DU SUD-OUEST. June 3, 1954 [June 11, 1953], No. 16467/54. Class 4. A helicopter rotor system comprises a freely tiltable rotative hub supporting, through diametrically opposite articulated connections spaced from the hub axis, the roots of two variable pitch blades also connected to the hub by members adapted to supply, between the blades and hub, a restoring force about the longitudinal axis of the blades increasing with increase in blade pitch, the hub also supporting two balance weights symmetrically disposed on a hub diameter perpendicular to the longitudinal axis of the blades, and a device directly connected to horns on the blades for cyclic pitch control. In Fig. 2, two blades 2A and 2B are connected to the hub 3 by rods 10A, 10B with articulated ends 11, and by members 12 which may consist of a laminated bundle of springs, and may extend through the hub from blade to blade. The hub also supports two masses 8 on arms 9. A control-rod 5 extending through the hub swivellingly supports at 14 a crows-foot 6 universally pivoted at 13 to two arms 7A and 7B rigidly attached to rods 10A and 10B for pitch control, raising or lowering rod 5 giving a collective pitch change, and tilting rod 5 giving a cyclic change. In operation, a cyclic pitch adjustment of the blades gives rise to unequal couples exerted on the hub by members 12, and the hub tilts progressively under the inertia oe masses 8. When a disturbance displaces the tip path plane, the blades affect the hub so that the diameter ab thereof describes a planparallel to the new tip path plane, but the gyrof scopic inertia of masses 8 constrains the diameter gh to remain in its former plane, and the hub rotates. A force is thus transmitted back to the blades, and crows-foot 6 to tilt the control member 5 to a new position to retain the same cyclic pitch setting despite disturbance of the tip path plane. The blades may be driven by jet propulsion units mounted thereon, or from an engine in the fuselage. The hub and pylon construction is shown in Fig. 3, wherein the pylon 1a bears a universal joint 21 mounting the hub and a thrust bearing 22 for transmitting lift, and contains a sliding universal joint 35 for control member 5. An extension 25 of the hub has spherical flanges 29, 25a co-operating with flanges 30 on the pylon and 26a on a chamber 26 surrounding the pylon, to seal this chamber. Flexible pipes 32 extend from the chamber to the blades, and the chamber is fed from a duct 28 with gas under pressure. The arms 9, Fig. 2, may bear small aerofoil elements, to which the masses 8 may be pivoted about vertical axes to accommodate quickening and slowing of the rotational speed of the hub.

Title: Improvements in Artificial Legs.
Inventor: GERARDIN MARCEL
IPC: A61F2/60
Filed: 1919-07-02
Abstract: 129,281. Gerardin, M. Dec. 11, 1917, [Convention date]. Limbs, artificial.-Comprises means for supporting and cooling artificial legs. The stump 3 of the limb engages the socket or bucket 2 like a piston fitting in a cylinder. When the limb is relieved from weight, the socket falls relatively to the stump and air is drawn in under the stump through the inwardly-opening valves 6. On the weight being re-applied, the valves close, and the enclosed air cushions the stump in its downward movement relatively to the socket. The air gradually escapes between the stump and the walls of the socket and, in so doing, keeps the stump from being overheated.

Filed: 1927-06-22
Abstract: 287,364. Haddan, R., (S÷rlandske Elektriske Apparatfabrik). June 22, 1927. Switches, quick-action, adapted to be rotated in either direction, comprise a driver 3 rivetted to a washer 16 on the spindle 1 to form one journal for the latter, and a rotatable disc 4 to which the moving contacts are attached, these members being interconnected by a double-wound spring 5. The disc 4 carries two pins 10, 11 forming pivots for two spring-controlled levers 12, 13 the ends of which are adapted to engage projections 9 corresponding to the number of switching positions. Rotation of the spindle 1 and driver 3 strains the spring 5, but movement of the contacts is prevented by one of the levers 12, 13 engaging the appropriate projection 9 until the driver 3 is sufficiently rotated to move the lever about its pivot, whereupon the spring 5 imparts a quick movement to the disc 4 by means of an abutment 6. Abutment 6 is riveted to the disc 4 by means of tongue 21 and rivet 24 which also secures the pins 10, 11, and the cover 20 is secured to the base by screws 22 which also secure the cup 8 by means of lugs 23 thereon. The mechanism is protected by a cover 26 and by means of the spring 14 the impact between the levers and projections 9 is softened.

Abstract: 379,776. Signal lamps. GENERAL RAILWAY SIGNAL CO., Rochester, New York U.S.A.-(Assignees of Field, O. S. ; Rochester, New York, U.S.A.) June 9, 1931, No. 16793. Convention date, July 23, 1930. [Classes 75 (iii) and 75 (iv).] Lantern screens; supporting.-The colour light of a railway or like signal issues from the signal casing through a conical passage 41 which is formed with longitudinal light-reflecting ribs 42 to diffuse any entering external light and so prevent a false signal being given by the return of such light through the signal. The colour light is selectively given by a spectacle 37 operated by a motor unit having permanent field magnets 50 which by means of their magnetically-conducting supporting frame plates 44 co-operate with an armature comprising transverse vanes or ears 58, 59 at the ends of a spindle 57 normally or reversely energized by a surrounding winding 56. The assembly shown in Fig. 2, comprising the spectacle and motor mounted in the casing 32 containing the conical diffusion passage 41 and the detachable lamp and reflector unit LU which is plugged into the said casing, is housed in an outer casing, Fig. 1, being supported therein by its bracket 7 which has a pin 8 to engage a lug 10 and by spring catches 12 which engage side lugs 11. This outer casing is hinged at 4 to a cap 2 angularly. adjustable on its supporting post 1 by adjusting the screw connections 3 to the strap-iron 3<2>, which is fixedly located by a lug 4<1> engaging a socket on the post 1. The outer casing is provided with sighting and crossed-hair apertures 16, 17, with a condenser lens 19, and with an auxiliary ribbed glass 23 to give a close-up beam at an angle to the main beam. The movement of the spectacle is limited by the armature vane 58 abutting against stop screws 64 and any tendency to rebound is prevented by a friction flywheel FF. The spectacle is returned to the neutral position by one or other of two pivoted weights 71 which have pins to engage slotted links 67 attached to an arm 66 on the armature spindle ; when the armature reaches the neutral position the pivoted weight abuts on a stop screw 73 and the restoring force being so removed the armature is dead-beat. The pivoted weights 71 carry electric-contact making springs 74. Fig. 11 shows a condenser lens 191 of the Fresnel type with a ribbed central portion 23<1> to give the angular close up beam 87<1>. The light from the lamp 33 and reflector 35 is brought to a focus 36 behind the spectacle 37. Any external light entering the signal will meet reflecting surfaces such as 43<1>, Fig. 11, situated in front of such focus and will be re-directed out of the signal in a non-parallel manner and in a direction different from the parallel main beam, as indicated by the rays 88. Specification 275,942, [Class 75 (iii), Lamps &c., Details &c.], is referred to.
