Patent DK-90390-A (DK)
Inventor: SPAANBERG SVEN
IPC: E03C1/28
Filed: 1990-04-10
Abstract: A clamping ring 1 for securing covering material, especially floor covering material 4, against the inner side 5 of a well, especially a floor well 6, is split and compressible in the radial direction counter to the action of a spring force, which is intended, when the ring is mounted in the well 6, to expand the clamping ring 1 in the radial direction until it bears against the covering material 4 and pins this against the inner side 5 of the well 6. In order that the clamping ring effectively and throughout its life secures the covering material, without the said spring force making the ring difficult to handle during assembly and thereby causing havoc, the clamping ring 1 is produced such that it expands by virtue of at least one spring member, preferably a helical spring 7, which is fitted between two end parts 8, 9 of the ring 1, which spring member 7 is compressible by the end parts 8, 9 being forced peripherally together. <IMAGE>

Title: Improvements in and relating to power transmission gearing
IPC: F16D13/70
Filed: 1923-01-02
Abstract: 213,021. Osborn, A. E. Jan. 2, 1923. Controlling variable-speed or reversing gearing in conjunction with a main friction clutch. A spring or the like 22, Fig. 1, is arranged so that a gear member 14 may normally be moved without the spring acting, but upon the gear member being restrained from moving, as by striking an obstruction, the spring yields and allows the clutch controlling-means 13 to move on and operate the clutch. As applied to reversing- gearing, a shaft 20 driven from the clutch 11 carries a splined sleeve 14 with a dog-clutch end 14<1> adapted to engage a like clutch end 44' on a driven hollow shaft 44 for forward driving, as shown in Fig. 1. For reversed driving, the sleeve 14 is slid to the left, disengaging the dog clutch and carrying with it gears 30, 40 into mesh respectively with intermeshing idlers 32, 33, Fig. 2. The gear 30 is secured to the sleeve 14 and the gear 40 is splined to the driven shaft 44. A spring 21 yielding in one direction allows the gear 40 to lag behind in its longitudinal movement. When the gearing is to be operated, a double cam 13 is moved one way or the other along with the sleeve 14 and gears 30, 40. The sleeve 14 moving to the right may be obstructed by the ends of clutch dogs 14', 44<1> clashing, and moving to the left may be obstructed by the teeth of the gears 30, 32 striking end on. According to the invention, the spring. 22 is adapted to yield for movement in both directions, so that in any case the double cam 13 can move on and, through levers 12, engage and disengage the clutch 11 as required. For this purpose, there is a loose washer 25 at each end of the spring 22. In a modified reversing-gear, there are single idlers meshing with an internal driven gear.

Title: Insulation tester for low-tension installations
IPC: G01R27/02
Filed: 1960-01-05
Abstract: 876,303. Testing insulation. ALLMANNA SVENSKA ELEKTRISKA A.B. Jan. 5,1960 [Jan. 13, 1959], No. 310/60. Class 37. In an arrangement for testing insulation for a fault, the time integral of a surge current from a capacitor C, across a gap G, causes a deflection in a meter A. The meter which is an ammeter having a mechanical response time longer than the surge current duration is protected by a capacitor C2 having a capacitance of the same magnitude as the surge generator, and a resistor R2. A resistor R1 determines the time of rise of the surge current, and a resistor R provides a discharge path when the insulation is satisfactory. C1 and R3 represent the capacitive and resistive components of the installation.

Abstract: 416,967. Coating pipes. STAVELEY COAL & IRON CO., Ltd., Hollingwood, near Chesterfield, and FABRY, R., 7, Devonshire Road, Totley Rise, both in Derbyshire. Jan. 9, 1934, No. 864. [Class 99 (ii).] In a machine for coating pipes or the like with plastic material, e.g. a mixture of pitch and asbestos, of the kind comprising means to revolve the pipe, means to feed the plastic material on to the pipe and means to move the pipe and the feeding means relatively to one another in the longitudinal direction of the pipe, one or more strickling plates are located adjacent to the pipe surface and are so inclined to the axis as to wipe the applied plastic material forwardly along the pipe during its rotation. The pipe 49 is mounted between a headstock 44 and a tailstock 45 on a carriage 41 carried by wheels 42, 43 running on rails 65, and is provided with end plugs 50, 51 held in place by a rod passing through the tube and adapted to be engaged by conical bosses 55, 56 on the head and tail stocks. The pipe is rotated from a motor 60 through a chain drive 59 and a pinion which engages a spur wheel 57 on the boss 56. The carriage 41 is driven longitudinally by a reversible motor 61 through a reducing gear 62 and a chain 63 engaging one of wheels 43. The wheels 43 are double flanged and the wheels 42 unflanged to facilitate accurate guiding of the carriage. The means for supplying the coating material comprises a jacketed heated vessel 11 for the liquefiable constituent, e.g. pitch, a shoot 25 for the solid constituent, e.g. asbestos, and a jacketed heated mixing chamber 22 having an outlet pipe 34 leading to a valve controlled nozzle 36 situated above the pipe 49. The vessel 11 and the chamber 22 are provided respectively with stirrers 14, 31, and a conveyer 35 is situated in the outlet pipe 34. A byepass 39 conducts excess material unable to pass the valve 37 back to the chamber 22. Hot gases from the jacket 17 surrounding the vessel 11 are conducted through a conduit 19 to the chamber 28 beneath the shoot 25 and pass through the material as it passes over the screen 26. The strickle plates 72, 73 are carried by slides engaged by guides 71, are retracted by springs 74, and are advanced against stops by hydraulic cylinders 75 each provided with a screwed rod 76 engaging a lug 77 on the slide. The strickle plates are electrically heated, are inclined downwardly towards the pipe surface, e.g. at an angle of about 45‹ to the vertical tangent plane to the pipe when the centre of the plates is level with the pipe axis, and are inclined longitudinally to the axis of the pipe at such an angle that the line of contact lies approximately at right angles to the helical path traced over the coating by the plates.
