Title: Improvements in resilient struts for use more especially in connection with the landing wheels of aeroplanes
IPC: B64C25/60
Filed: 1935-08-15
Abstract: 461,144. Shock-absorbers. RIBBESFORD CO., Ltd., and ONIONS, J. H. Aug. 15, 1935, No. 22936. [Class 108 (iii)] In a resilient strut particularly for aircraft comprising telescopic, tubular, plunger-andcylinder members 14, 10, relative movement of which is resisted by flow of liquid through one or more restricted passages, a floating piston 38 separates the liquid from compressed gas or air which supports the normal axial load. As shown in Fig. 1, the plunger-head 15 contains a series of large apertures 19 and a small central opening 20, flow of liquid through which is regulated by a centrally-apertured flutter-valve 17 such that, on compression of the strut, liquid flows relatively freely through the apertures 19 and valve-aperture 21 while on extension the valve 17 is pressed downwardly, the flow of liquid being restricted by the opening 20, the apertures 19 being closed by the valve. The lower end of the cylinder 10 is closed by a plug 22 secured by three diametral pins &c. 23 and provided with an oil-filling passage 25. Compression of the strut is arrested by an annular buffer 27 resting on the plug 22 and extension by a resilient ring 28 surrounding the plunger 14 and resting on a spacing tube 30. A preferably resilient sleeve 43 acts as a stop for the floating piston 38, the sleeve bearing against another plug 32 which closes the outer end of the plunger 14, and is fitted with an air or gas inlet valve 37. The relative disposition of the parts may be reversed as in the construction shown in Fig. 2. In this case the upper plug 45 supports a central rod or tube 46 carrying at its lower end a piston 47 having small apertures 48, the piston and tube working with clearance in the body and head respectively of the plunger tube 14. The valve 17 is normally spring-pressed to close the apertures 19 in the plunger-head 15. The floating-piston 38 may have an axial guidestem 53 slidable in the tube 46. The plug 45 comprises portions having bevelled edges 54, 56 adapted to force outwardly into contact with the cylinder 10 a packing ring 58 when the two portions are clamped axially by a nut 57. A plug 59 closing the lower end of the plunger tube 14 is sealed by an L-section packing-ring 63 preferably of rubber.

Title: Appratus for winding a rotor of an electric motor and anchoring  wires forming the rotor windings in slots in segments of a  commutator secured to the rotor
IPC: H02K15/09
Filed: 1973-05-15
Abstract: 1427176 Winding rotors of electric motors AXIS SpA 15 May 1973 [17 May 1972] 23066/73 Heading B3A Apparatus for winding a rotor 5, Fig. 2, of an electric motor and anchoring the rotor windings in slots (124), Figs. 13-15, 17 (not shown), in segments of a commutator 7 secured to the rotor comprises an automatic rotor winding machine having at least one winding arm 12, Fig. 3, a rotatable structure 73 carrying a slot position ascertaining means 78, wire guide surfaces 102, 104 and wire insertion tools 80, 82, a control device 138 for the rotatable stricture which is responsive to the slot position ascertaining means to rotate the structure and bring it into precise angular positioning with a commutator slot, and means 80A for actuating the tools to insert the wire and anchor the windings. The rotor is clamped in jaws 9 and the winding arm rotates about an axis A-A orthogonal to the axis X-X of a chuck 3, 3A of the machine for performing the winding operation. An elastic tooth 34, Fig. 4, is provided in one of the jaws to engage the edges of slots 5A of the rotor to cause angular movement thereof. A collet unit, including a hollow member 41, 41A mounted within the chuck 3, 3A, provides angular movement of the rotor between winding operations. This is due to connection of member 41 with a yoke 52 which can oscillate between adjustable stops 54, 56, or stops 54, 58A, Fig. 5. Such angular positioning of the rotor provides an approximate preliminary angular positioning of the commutator segment. The rotatable structure 73  carries a wire retaining collet 76, an optical centering probe 78, a blade insertion tool 80 and a wire bending tool 82. Shaped guide elements 102, 104 on the structure form a guide opening for the wires which are inserted using the tools 80, 82 and can be cut along the commutator surface. The probe accommodates a series of optical fibres (114) which are used to direct light towards the commutator. An optical system (118) forms an image of the commutator reflection surface on a reading plane (120) between reading bands (120A), (120B). The bands are monitored by bundles (128A), (128B) of optical fibres adjacent photoelectric transducers (130A), (130B) arranged in a bridge (132) whose output 134, Fig. 11, is connected to a computer 136. The output provides a correction signal to the structure 73 while the bridge (132) is unbalanced. The correction signal operates the control unit 138 which in turn rotates a lead screw 142 via a belt drive 140 and shaft 138A. Movement of a nut 144 causes angular movement of an arm 146 integral with a sleeve 71 of the structure 73. When the centered position of the structure has been attained, the winding arm 12 feeds the end of the wire to the collet 76 and the collet clamping control 76A, wire bending tool control 82A and blade insertion tool control 80A are operated in sequence to force the wire into a commutator slot.

Title: Improvements in or relating to the production of sound records for synchronous working with kinematograph pictures
Filed: 1929-07-31
Abstract: 318,143. Mayfilm Ges., (Assignees of Lucht, E.). Aug. 28, 1928, [Convention date]. Producing sound-records in association with kinematograph pictures.-Relates to processes for making sound records in conjunction with the production of kinematograph pictures, the object being to produce a sound record which is such that when reproduction from the record is effected, only those sounds appertaining to the picture are heard, all extraneous noises being cut out. According to the invention, a primary sound record is first made on a cylinder, disc, film, &c., synchronously with the taking of the kinematograph pictures, all sounds and noises which occur at the time being recorded. Sound is then reproduced from the primary record, the reproduction being transmitted, for example through head-phones, into a noise-proof room, where an improved or secondary record is to be made, identical in essentials with the original record, and in synchronism with the kinematograph pictures, but without the original extraneous noises. The head-phones are either used by a conductor (for orchestral recording, or by vocalists &c. who are to make the secondary record the sound-reproduction by the head-phones in either case serving as a guide for the conductor or the artists responsible for making the improved record. The primary record may serve not only as a synchronizer, in the making of the secondary record, but may also reproduce necessary instructions given by the conductor or producer during the making of the original record. With the aid of the secondary record, a tertiary record may be prepared, in which the scenes with their sounds or noises are given in natural sequence, in cases where such sequence was not followed in making the original kinematograph and sound records.

Abstract: 863,046. Wind motors. ROTAX Ltd. Oct. 2, 1959 [July 23, 1958], No. 23651/58. Class 110 (3). A wind motor for driving an alternating electric current generator having a plurality of radial blades 10 angularly adjustable about their radial axes comprises in combination with a rotor-driven spindle 20, a differential mechanism 22, 27, 24 interconnecting the spindle with a surrounding hollow spindle 25 having a gear 26 formed thereon or secured thereto, at least one non-rotatable and axially movable screw 37, a rotatable nut 36 mounted on the screw, gearing 34, 35 driven by the hollow spindle 25 for rotating the nut, an axially movable member 19 operable by axial movement of the screw 37 for imparting angular regulating movements to the rotor blades 10, a friction clutch 23, 30, 31 for controlling the action of the differential mechanism 22, 27, 24 on the hollow spindle 25 and speed-responsive centrifugal means 44 for controlling the clutch so that variations of the air speed or the load are accompanied by compensatory angular adjustment of the rotor blades. To counteract the centrifugal forces on the blades, the stub axle 12 of each blade carries a blade actuating pin 16 having a partspherical portion 17 which bears against an abutment 15. Three non-rotatable screws 37 may be provided and each screw carries two adjustable nuts 39 situated on either side of a flange 40 connected to a sleeve 29 forming part of the friction clutch. The arrangement is such that at speeds below a given speed, the flange 30 is moved by the springs 42 into contact with the clutch member 23 so causing the worm 26 to be rotated in one direction. At higher speeds, the centrifugal masses 44 cause the flange 30 to be moved into contact with the fixed component 31 so causing the worm 26 to be rotated in the opposite direction. Rotation of the worm 26 causes axial movement of the screws 37 which cause the member 19 to impart angular movements to the rotor blades 10. If the axial movements of the screws 37 is such that the nuts 39 engage the flange 40, the movable flange 30 will be disengaged from the component 31 or component 23 respectively and the centrifugal mechanism rendered ineffective. In a modification, Fig. 3 (not shown), the worm wheel 26 is replaced by a spur gear which drives the nuts through a compound gear train and the screw threads on the screws 37 are replaced by re-circulating ball threads. A plurality of flyweights are also provided to balance the centrifugal forces on the rotor blades.

Title: Improvements in or relating to line concentrators
Inventor: ABBOT GEORGE FOLLET
IPC: H04Q3/54
Filed: 1962-06-20
Abstract: 1,000,046. Automatic exchange systems. WESTERN ELECTRIC CO. Inc. June 20, 1962, No. 23674/62. Drawings to Specification. Heading H4K. In a line concentrator system having a corresponding expander associated with the line terminations at a central office, the operations are controlled by a common circuit which on a service request allots an idle trunk and transmits its identity to the concentrator. On an originating call, a signal is sent to the control circuit to establish preference over terminating calls, and the line requesting service is identified in two stages by means of tens and units counters driven by pulses which pass also to the control circuit to drive synchronous counters thereat. A trunk selector is similarly driven in search of an idle trunk by pulses which pass also to the concentrator. As regards terminating calls, the sleeves of the lines concerned are continuously scanned, and scanning is stopped when a line bearing a service request is found. If, however, all the trunks available to a particular group of lines are busy, then the line terminations to the scanner are disabled. The operations subsequently are generally similar to those in the case of originating calls. To even out the traffic over the group of trunks means is provided in the trunk selector for applying a false busy condition periodically during the course of the scanning cycle. Specification 957,476 is referred to.
