Title: Taping heads for cable-making machines
IPC: H01B13/08
Filed: 1962-10-16
Abstract: 984,781. Cable taping machines. J. KRAFT, J. KRAFT, and A. KRAFT, [trading as J. A. KRAFT]. Oct. 16, 1962 [Oct. 20, 1961], No. 39148/62. Heading B8G. A taping head for cable-making machines comprises a plurality of ribbon discs arranged on a rotor, characterized in that each ribbon disc is mounted on two pins or journals provided with collars to keep the ribbon discs in their operative position, which pins or journals are movable axially away from one another for the positioning of the ribbon disc. In Fig. 1 the ribbon winding 1 is supported on one face by a hub 4 and on its other face by a journal 12, the whole being so designed that the journal 12 can be moved axially away from the hub 4 to permit removal or replacement of the winding 1. A journal 6, riveted to a metal plate 7, supports ball bearings 5 on which the hub 4 is mounted. Secured to the plate 7 is a bridge member 18 that spans the ribbon winding 1 and carries a non-rotatable nut 17. Within the nut 17 is a threaded sleeve 16 housing ball bearings 14 within which the journal 12 is rotatably mounted. By rotating the sleeve 16, relatively to the nut 17, the journal 12 can be made to move axially relatively to the hub 4. A holding disc 20, rigid with the sleeve 16, provides means whereby the sleeve 16 can be rotated. The plate 17 may be a rotor of a cable winding machine and may carry a plurality of ribbon windings 1. The device includes centrifugally actuated brake means, Figs. 3, 4 and 5 (not shown), that acts on the disc 20 when the plate 7 is revolving to prevent the disc 20 from being accidently rotated whilst the winding machine is in operation. The hub 4 is part of a brake drum 3 that can be braked by upper and lower brake shoes 53, 54, Fig. 9. The shoes are connected on one side through a known linkage 55 to means for regulating the ribbon tension (not shown). To cancel the effect of centrifugal forces, the right-hand side has a swivel member 56 to which the levers 55 are linked, this arrangement is stated to be well known. On the left-hand side, because centrifugal forces will tend to relieve the pressure of the upper shoe 53 and increase the pressure of the lower shoe 54, the two-armed lever 66 is provided carrying a mass 69 such that as the mass tends to rock the lever 66 clockwise when subjected to a centrifugal force, this rocking of the lever 66 will pull the upper shoe 53 on to the brake drum to increase its pressure and ease the pressure of the other shoe 54. By turning the screwthreaded nut 63 the setting of the brake shoes can be adjusted. In a further embodiment, Fig. 6 (not shown), the hub 4 is also made displaceable on rotation of a disc similar to the disc 10, the discs 10 and 20 being toothed along their outer periphery and interconnected by a pinion to ensure simultaneous rotation. A centrifugally actuated locking means acts on the pinion to prevent rotation of said discs while the plate 7 is in motion.

Filed: 1972-09-06
Abstract: 1409271 Transportation system M BARTHALON 6 Sept 1972 [7 Sept 1971] 39437/72 Heading B7L A transportation, system comprises a cabin 1 suspended beneath a track 2 by pairs of suspension members 12, 13 &c. connected between the cabin roof and wheeled or slide trolleys 11, 21 &c. which move along the track and at least some of which are propelled, the pair of suspension members associated with each trolley consisting of a rod extending from an upper pivot 14 within the trolley between guides 17 through the cabin ceiling, the lower end of the rod having a bellows 15 secured thereto filled with pressurized air, the top of each bellows mounting rollers 3 which bear against a runway 4 on the cabin. Compressed air jacks 18, 19 acting in a horizontal direction connect the cabin roof to guides 17 and the bellows and jacks are supplied with high pressure and low pressure air respectively from a reservoir 52, Fig. 7, the eight bellows and eight jacks being connected in pairs associated with the four corners of the cabin, e.g. bellows 15, 25 and jacks 18, 28 are connected in pairs. The chambers of the jacks and bellows of each pair are connected to provide equal pressure therein, or in the case of the bellows the conduit providing this connection includes a calibrated valve 58 to maintain a pressure difference between the chambers. The jacks balance forces exerted laterally on different parts of the vehicle whereas the bellows are supplied with pressurized air through threeway valves 61, 62 controlled to correct the longitudinal trim of the cabin and also through valve 63 which corrects transverse trim. The valve 63 is operated by a pendulum 68, Fig. 9, which according to the displacement of the cabin from the apparent vertical will supply air through either of conduits 74 or 75 to the bellows on one or other side of the cabin. Hence roll, pitch and yaw of the cabin can be controlled. Hydraulic shock absorbers 20 are connected between guides 17 and by a linkage 6 to one of each of the rollers associated with each bellows. Stops are provided to limit movement about pivots 14. In a modification the guides through which the suspension rods pass are articulated to the trolleys and the rods themselves pivoted to the cabin. The bellows are situated at the upper ends of the rods and jacks 18, 19 replaced by a double pistoned jack between the rods, one piston being connected with each rod guide. In further modifications the suspension members are formed by rods pivoted to the cabin roof and having yokes at their upper end pivoted about orthogonal axes to the trolley. At the upper end of the rods either bellows are provided or oleopneumatic elements which satisfy the same function as the bellows.

Title: Yarn traverse mechanism
IPC: B65H54/32
Filed: 1974-09-11
Abstract: 1509002 Yarn traverse mechanism ERNEST SCRAGG & SONS Ltd 2 Sept 1975 [11 Sept 1974] 39586/74 Heading D1J A yarn traverse mechanism that can be used for winding packages with conical ends comprises a sledge 22 having a cylindrical body 22a, a yarn guide 23 attached to the sledge 22, a primary slide 24a, 24b co-operating with the cylindrical surface of the body 22a and supporting and constraining the sledge 22 to move in a linear path while allowing it to rotate, means for reciprocating the sledge 22 along said path and means 27, 28a, 28b adapted to rotate the sledge 22 about the axis of the cylindrical body 22a as it reciprocates along said path. In Fig. 2 the sledge 22 moves back and forth along the channel defined by the space between the fixed parallel slides 24a, 24b. The sledge 22 has a depending pin 26 that may, for example, co-operate with a helical cam groove in a cylindrical cam roll (not shown for purposes of clarity). The helical cam groove thus causes the cylindrical sledge to reciprocate along the linear path between the fixed parallel slides 24a, 24b. A second pin 27 is eccentrically disposed on the end face of the sledge 22 that is opposite to that to which the pin 26 is attached. The pin 27 is constrained to move along a linear path defined by a pair of parallel rails 28a, 28b. When the rails 28a, 28b are parallel with the slides 24a, 24b the reciprocation of the thread by the thread guide 23 is equal to the stroke of the sledge 22. When the rails 28a, 28b are inclined relatively to the slides 24a, 24b the sledge is caused to oscillate about the polar axis of its cylindrical portion 22a and the traverse reciprocation of the thread guide 23 is then less than the stroke of the sledge 22. A simple mechanical linkage (not shown) between arms carrying the package being wound and the slides 28a, 28b causes a progressive change of angle of the slides 28a, 28b to cause a package with conical ends to be wound.

IPC: D06B3/08
Filed: 1929-12-27
Abstract: 336,174. Schlumpf, J. Dec. 27, 1928, [Convention date]. Addition to 316,227. Hank-type apparatus. - In apparatus for regulating or controlling the traversing movement of skeins during treatment in a liquid bath in which they are dipped by rotation of a crank arm carrying a spool or roller, and according to the parent Specification which describes means for preventing any traversing movement during the movement of the crank from the lower to the upper dead-centre position, a coupling element is provided which rotates with the crank arm and carries a flat flange having radially-spaced cam tracks and a roller co-operating therewith, the roller being adjustable into the range of one or other of the tracks to control the engagement of the spool roller with either the rotary coupling element or a non-rotatable housing by axial movement of the element against spring action. A shaft 4 projects from the crank arm 3 and has rotatably mounted upon it a sleeve 10 carrying a spool 5 and a coupling element 12 which, through conical surfaces 11, can be engaged with the sleeve 10 when displaced along the shaft 4 by a spring 13 housed in a recess in the element. At the end of the coupling element 12 adjacent the crank arm, the element comprises a flat flange 15 connected to the crank arm 3 to constrain the element to rotate therewith, and cam tracks 38 - - 40 are formed on the face of the flange. The spring 13 urges the flange 15 against a roller 26 mounted in a sleeve 24 carried by a cam element 27 provided with a handle 28, rotation of which raises or lowers the roller 26 bv means of cams 29 - - 31 which engage a fixed abutment 32 on a bearing block 23 in which the sleeve 24 is disposed. The cams 29 - - 31 adjust the roller 26 to engage one or other of the cam tracks 38 - - 40 on the flange 15 and as these tracks are made of shorter length as they are disposed nearer the shaft 4, the periods during which the roller engages & track and so allows the spring 13 to engage the rotary coupling element 12 with the sleeve 10 may be controlled. The bearing block 23 is carried by an extension 22 of a ron-rotatable housing 18 formed with a coupling flange 20 adapted to engage a similar flange 21 on the sleeve 10 to hold the sleeve against rotation whenever the roller 26 is free of the cam tracks, the roller then pressing the housing along the element 12 towards the sleeve 10.

IPC: F01P7/16
Filed: 1959-11-24
Abstract: 940,475. Liquid cooling systems. SULZER BROS. (LONDON) Ltd. Nov. 11, 1960 [Nov. 24, 1959], No. 39887/59. Heading FIB. A liquid cooling system comprises a fan which is speed-variable independently of engine speed and produces a cooling air flow through a radiator, a radiator by-pass, and a thermostat responsive to the liquid coolant temperature, for controlling both the fan speed and the by-pass flow. Cooling water from a locomotive deisel engine 10, passes via thermostat 21 to radiator 11 and returns via pump 12. The radiator is air-cooled by a hydraulic motor-driven fan 16 supplied from reservoir 19 by pump 18. At low cooling-water temperature a valve 20 controlled by the thermostat 21 in the coolant circuit, opens to by-pass the fan motor 17 to reduce the hydraulic pressure thus stopping or reducing the speed of the fan 16. The pressure change causes a pressure-responsive pilot valve 25 which controls a hydraulic servomotor 15 to open a by-pass valve 14 in the cooling circuit of radiator 11. At higher temperatures, valve 20 is partially closed and increasing hydraulic pressure causes the by-pass valve 14 to close thus causing coolant to circulate through the radiator and causing fan 16 to operate effectively. Specification 897,500 is referred to.

Title: A single-pole or multipole electrical power circuit-breaker
IPC: H01H77/10
Filed: 1960-11-25
Abstract: 962,819. Electrically tripped switches. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. Nov. 25, 1960 [Dec. 7, 1959], No. 40615/60. Heading H2B. A circuit-breaker is constructed so that by suitable choice of the coupling between the movable contact carrier and the actuating mechanism the breaker may be tripped instantaneously or after a selectable time delay, the arrangement being such that prior to tripping in each case the electrodynamio action of the fault current produces movement of the contact carrier to open the main contacts and increase the pressure between the arcing contacts. The breaker shown in Figs. 2a and 3 comprises main and intermediate fixed contacts 3a, 3b which, with an arcing contact 4, cooperate with a movable contact 5 mounted on a carrier 7 pivoted at 8 to an insulating member 11 having limited rotation about a pivot 9. A detent 12 on carrier 7 normally engages a roller 14 of a rocker arm 13 which is actuated by rotation of a lever 16 about the pivot 9, the lever 16 being coupled to the breaker operating member through a latch (not shown) controlled by one armature 23 of an electromagnetic trip 20. The other armature 21 has an arm 22 engaging the member 11, while the connection between the trip energizing conductor 2 and the contact 5 is a flexible strip 6. Tension spring 17 provides contact pressure when the breaker is closed. If short-circuit current flows the strip 6 is flexed by electrodynamic force to roll the contact 5 about contact 3b until it bears on the arcing contact 4 and separates from contacts 3a, 3b. Subsequently members 12, 14 disengage and the springs 17, 18 assisted by the electrodynamic force separate contacts 4, 5, the latter moving to position I in Fig. 2a and the roller 14 moving into a recess 19. After this movement of armature 23 releases the latch controlling lever 16 which then rotates clockwise with members 7, 11, 13, the rotation of carrier 7 being limited by member 11 to allow the roller 14 to re-engage the detent 12 in readiness for breaker re-closure. If a time delay is required, the carrier 7 is coupled to the arm 13 by a rigid triangular member pivoted therebetween, Fig. 2b (not shown), so that contacts 4, 5 cannot open until the lever 16 is released. In another modification, Fig. 4a, only one main contact 3 is provided and the movable contact 5 is coupled to the operating lever 30 by a toggle 28 releasable by a pin 36 mounted on the contact 5, the toggle being reset after opening by a stop 37. Springs 34, 35 assist contact opening and spring 31 provides contact pressure. A time delay may be provided by making the toggle 28 rigid or replacing it by a rigid link.

Abstract: 953,418. Liquid filters. GENERAL MOTORS Ltd. Nov. 14, 1962 [No:. 14, 1961], No. 40622/61. Heading B1D. A filter unit 1 for a liquid filter comprises a pair of annular filter elements 2, 3 arranged end-to-end on a central support tube 4, one element 2 being formed by pleated synthetic resin-impregnated sheet filter material, such as filter paper, and the other element 3 being an annular mass of material the porosity of which is substantially greater than that of said sheet filter material. The other element 3 may be made of vegetable or other fibres, e.g. sisal grass fibres, or a mixture of sisal grass and other fibres especially cotton. Alternatively the filter element 3 may be made of cellular plastics material especially polyurethane foam. The element 2 may be made from a strip of synthetic resin-impregnated sheet filter material, especially paper, joined at its ends and folded about regularly spaced transverse fold lines to form an annular series of pleats 10, the ends of each pleat being individually sealed. Dimples 11 space each pleat 10 from an adjacent pleat and radial ribs 12 are impressed in the two parts of each pleat so as to provide drainage channels for filtered liquid. The element 3 may be placed directly against one end of the pleated paper element, or, as in Fig. 3, an annular disc 20 may be interposed between one end of the paper element 2 and the adjacent end of the other element 3 so as to seal the paper element 2 and provide a seat for the adjacent end of the other element 3. In operation, the two filter elements being in parallel and the rate of flow of liquid through 3 being substantially greater than through 2, the effect is to provide coarse filtration of a major portion of the liquid and fine filtration of a minor portion. When filter 2 becomes clogged a further period of full flow filtration through filter 3 can be obtained before it is necessary to change the filter element.
