Title: Improvements relating to control equipments for winding, hoisting, hauling and like gear
IPC: B66B1/12
Filed: 1936-10-13
Abstract: 485,088. Winding-apparatus. SMITH, G. D., SMITH, D. M., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Oct. 13, 1936, No. 27804. [Class 78 (v)] [Also in Group XXIX] Relates to control equipment for winding, hauling, hoisting, and like gears in which the winding motor is constituted by an electric motor and comprises an electrically actuated mine hoist wherein the speed of the winder is automatically controlled throughout the wind so as to conform to a selected speed, the value of which will vary in accordance with the position of the cage and will follow a predetermined programme. A pilot valve PV controls a servomotor S which determines the position of a dipper of a liquid controller LC forming a variable resistance in the rotor circuit of a windermotor WM. P indicates a source of pressure liquid, and D a drain or exhaust. A pump 1 is driven from the winder drum, and a changeover valve 2 changes the pump connection as the direction of winding changes. The pump supplies liquid to the lower end of a plunger 9 in a chamber 4 having an outlet 6 leading to a space 7 and exhaust 8. The upper end 11 of the plunger 9 is in communication with the pressure liquid. The plunger 9 is surrounded by a ported sleeve 15 the position of which is determined by a cam 21 having cam portions 22, 23 corresponding to the acceleration and retardation at the ends of the wind, the sleeve being connected to a lever 19 carrying the roller 20. Thus the plunger 9 of the pilot valve is positioned according to the winding speed, and the sleeve 15 according to the position of the cage or skip. The servomotor S comprises a piston 29 carrying a dipper plate 30 and connected by a lever 31 pivoted at 32, and a link 33 to lever 19. These features, as well as a relief valve 34 for preventing suction of air through leakage spaces into the chamber 4, are described in Specification 424,223. The driver's control lever DL operates the master controller 35 controlling the forward and reverse switches 36, 37 of the motor WM, and is connected through link 38, lever 39 and lostmotion device 40, 41 with the lever 19. When lever DL is in the ''off" position the lever 19 is raised. When moved fully to forward or reverse positions, the lever 19 is lowered on to the cam which thereafter determines the position of the sleeve 15. The driver may reduce the speed at any time, but would be prevented by the cam 21 from increasing it beyond the programme speed. The Provisional Specification, which states that the winding may be effected by a steam turbine or an internal-combustion engine, refers also to Specification 482,448.

IPC: G01B7/16
Filed: 1965-07-01
Abstract: 1,160,545. Measuring stretch or shrinkage of yarn. LEESONA Ltd. 19 Sept., 1966 [1 July, 1965], No. 27833/65. Heading G4H. The amount by which yarn stretches or shrinks after passing through, for example, a size bath 12, is measured by comparing the number of pulses transmitted to a first decatron counter 19 by a transducer 17 sensing the rotation of a roller 11 with the number of pulses from a second transducer 17 transmitted to a second decatron counter 21 as a roller 13 on to which the yarn 10 is wound after it is passed through the size bath 12 rotates. In the embodiment described the counter 19 counts up to a thousand pulses and then switches a diode in the control box 20 to prevent any further pulses being received by either counter. If the counter 21 has then counted 1,027 pulses it will display 27 to indicate a stretch of 2À7% but if, for example, a count of 965 is given the percentage, shrinkage is obtained by subtracting the indicated figure from one thousand. The counter 21 has three indicator dials which respectively indicate a percentage stretch of from 1% to 1%, 1% to 10% and over 10%.

Title: Improvements in or relating to loose-nailing machines
IPC: A43D69/02
Filed: 1925-11-06
Abstract: 265,298. British United Shoe Machinery Co., Ltd., and Gouldbourn, J. Nov. 6, 1925. Loose-nailing.-Relates to loose-nailing machines of the type, described for example in Specification 1494/93, wherein a nail raceway, naildriver bar, and feed-awl bar are swung in company to and fro parallel to the work feed path; and consists in obtaining a higher operating. speed by varying, by an alteration of the cams, the timing of the different operations of the machine cycle without increasing the rate at which the work is moved or the speed of return of the awl for a new feed. In particular a substantially increased angular time of the revolution of the cam shaft is devoted to the feed and return movements of the awl, the angular intes-val allowed between the descent of the driver and the awl is reduced and other movements in the cycle are speeded up. Stop mechanism is provided to arrest the cam shaft in a given position with in. creased certainty, to allow of this speeding up, and the driver bar is reduced in weight by using an aluminium alloy. In the portion of a nailing machine illustrated, a driving pulley 2 loose on the cam-shaft 1 is urged into engagement with a clutch member 3 by a spring 6, but is normally held out of engagement by pins 11 and a wedgeblock 12 engaged by a wedge on a yoke 14. The. latter is pivoted to a lever 17 to which is pivoted a latch 21 engaged by a cam lever 25 so as to retain the yoke in clutch-disengaging position. When the latch 21 is tripped bv a treadle rod 26 a spring raises the yoke, allowing the pulley and clutch member to engage. Movement of the lever 17 to open the clutch closes a brake-member 28 on a drum 29 on the shaft 1 by means of an eccentric 30. The brake can be opened by hand bv means of a handle 34 and eccentric stud 33 held in either of two positions by a spring bolt 36.

Abstract: 1,141,599. Polarizing apparatus. INTERNATIONAL BUSINESS MACHINES CORP. June 22, 1966 [July 2,1965(2); Oct.1, 1965(2)], No.27906/66. Heading G2J. A polarized light separator has an interface 16, Fig. 1, between a birefringent medium 11 and an isotropic medium 15 such that orthogonally polarized components of a beam of light 18 incident on the surface 16 at an angle lying between the critical angles of the birefringent medium emerge in coplanar parallel paths 19, 24, the optical path lengths of the components from the point of entry of beam 18 into medium 11 to a plane perpendicular to paths 19, 24, being equal. As shown a prism 11 of sodium nitrate has its lower refractive index matched to a plate 15 of sodium fluoride so that a beam 18 polarized parallel to the optic axis of prism 11 passes through the interface 16 to be totally or specularly reflected at surface 20, which is either coated with a material of lower refractive index than plate 15 or with a specularly reflecting coating, so that beam 24 is parallel to the orthogonally polarized beam 19 which has been totally reflected at interface 16. The output surface 22 is adjusted to equalize the optical path lengths and it may be angled to correct for refraction distortion. In a modification, plate 15 is replaced by a liquid, with surface 22 formed by an adjustably mounted thin plate. Alternatively plate 15 is of the same birefringent material as prism 11 and interface 16 is an isotropic material having a thickness as small as one wavelength. In a modification. Fig. 4 (not shown), an isotropic prism (40) which is a parallelogram in crosssection has birefringent plates (45, 47) on two adjacent sides with their optic axes orthogonal to one another. Alternatively the second plate may be omitted and that side of the prism formed as two parallel portions which are offset with respect to each other. In further forms, one or two layers of birefringent material are inserted in a slot or slots in a trapezium shaped block of isotropic material, and when two layers are provided, each has its optic axis perpendicular to that of the other. In another modification the isotropic material is a liquid, such as oil, and appropriate plates are suspended therein.

Filed: 1932-10-10
Abstract: 406,405. Liquid-fuel burners. SOUTER PROPRIETARY, Ltd., R. F., 36, Little Collins Street, Melbourne, Australia. Oct. 10, 1932, No. 28200. Convention date, Oct. 9, 1931. [Class 75 (i).] Liquid fuel delivered through a pipe 14, Fig. 1, and inclined passages 31 in a conical, pyramidal, or cylindrical head 26 flows as a thin film during vaporization along grooves 32 in the outer surface of the head which is covered by a hood 33. The vapour produced is ignited on meeting a current of air which rises between the pipe 14 and the inner flange 22 of an annular hot-plate 20 and is directed outwardly by a deflector 25 so as to carry the flames through the gap between the hot-plate and the hood. The flames then pass around the outer surface of the hood and are met by a second supply of air directed inwardly by a deflector ring 18. The deflector ring 18 and hot plate 20 are supported by ribs 17 on a body member 10 attached to the combustion chamber 12 and the fuel pipe 14 is supported by a spider 13 on the member 10. The ribs 17 prevent the outer air currents from swirling. An overflow pipe 24 removes unvaporized fuel from the hot-plate 20. The lower surface of the hot-plate is covered with asbestos or other heat-insulating material 23. Fig. 3 shows another construction in which the hotplate is carried by a flanged plate 37, which can be adjusted relatively to the body member 10 to regulate the outer air supply, and the fuel issues from the pipe 14 either at the top of the head 26 or through radial pipes 52. The hood 33 is supported by screws 39 on the head 26 and is formed with internal perforated partitions 40, 42. After combustion has been started water which may have been preheated is supplied to the chamber 44 above the partition 42 through a pipe 47 passing centrally through the pipe 14. The steam produced in the chamber 44 is directed by the holes 41 on to the head 26 and keeps it free from carbon deposit. Alternatively steam may be supplied to the pipe 47 and the chamber 44 being dispensed with. The burner may be operated with forced instead of natural draught, all the air being supplied through the central column 36 which is then formed with lateral holes 36<1> for the outer air current supply. A metal or fireclay disc forming an auxiliary hot plate may be provided above the hot plate 20. In another construction the fuel is delivered to the conical head by a pipe arranged above the head. The Specification as open to inspection under Sect. 91 comprises also a burner in which the air is delivered by a conical passage 50 above a shield member 51 surrounding a conical head 26 as shown in Fig. 6 (Cancelled). This subjectmatter does not appear in the Specification as accepted.
