Title: Fixation of insulators for electric wires
IPC: H01B17/20
Filed: 1927-03-07
Abstract: 267,156. Stemmann, A. March 8, 1926, [Convention date]. Insulators, securing to supports.- Porcelain &c. insulators c are secured to their supports by expanding the end of the support a into an undercut recess b by means of a wedge e. In the construction shown in Fig. 1, the metal sleeve a is slit at its inner end and extends outwardly in the form of a tube a<2>. The wedge e is secured to a pin f and is caused to move relatively to the slit part of the sleeve to expand the latter. A lining of elastic material d may be provided in the recess. Fig. 2 shows a modification in which the sleeve a is internally threaded at a<3> for attaching to the support f and the wedge e is moved to and locked in operative position by a set screw g. In another modification the set-screw g may be extended outwardly to form the support. The apparatus in which the parts are assembled is shown in Fig. 8, and comprises two connected frames 1, 2. In the lower frame 1 is non- rotatably guided a threaded bolt 4 on which works a hand wheel 5 acting on two plates 6, 7 with an interposed spring 8. In the upper frame a threaded tubular pin 10 conveys pressure through a spring 13 to a bolt 12 which bears on the end of the bolt 4. The sleeve a is secured on the bolt 4 by the wedge e and inserted into the insulator head c by the pressure of the bolt 12 acting through the bolt 4. The hand wheel 5 is then turned down to draw the wedge outwardly, the plate 7 meantime bearing on the end' of the sleeve a. Graduations on the rods 9 and 12 indicate the applied pressures.

Title: Improvements in and relating to magnetos
IPC: H02K21/38
Filed: 1920-03-02
Abstract: 139,782. FÚrat, E. T. Feb. 18, 1918, [Convention date]. Addition to 139,781. No Patent granted (Sealing Fee not paid). Inductor machines.-In magnetos' of the type described in the parent Specification, the mechanical speed-reducing gear between the shaft and the distributor is located within the hollow pole element. The pole-pieces a, b are formed in one piece with the operating shaft 42 and are assembled on the non-magnetic sleeve 7. The other pole-pieces not shown are likewise assembled on the sleeve 7 and are coupled by the ring 43. The bearing 37 is accommodated in the cavity 44 and supported on the extension 36 of the bearing 35. The Specification as open to inspection under Sect. 91 (3) (a) also describes the use of a terminal socket 45 which is soldered to the cable 46 and is supported by the insulated bush 29, to which is screwed the spring-actuated contact 47, thus connecting the distributor to the secondary winding of the armature.

Patent GB-374100-A (GB)
Title: Improvements in non-reversing hand cranks for use in starting internal combustion engines and like operations
IPC: F02N1/02
Filed: 1931-02-28
Abstract: 374,100. Hand driving-mechanism. WALTER, C., 19, Heckinghauserstrasse, Barmen, Germany. Feb. 28, 1931, No. 6371. [Class 136 (ii).] A non-reversing hand crank for starting engines, actuating hoisting winches, or like operations is provided with a clamping coupling and a reverse lock so that, on rotating the hand crank in one direction the coupling causes a radially yielding intermediate member to grip the engine or other shaft to be rotated, while the grip is released and the intermediate member or the hand crank is arrested by the reverse lock on backward rotation of the shaft. In one form, Figs 1 and 2, the shaft g to be actuated carries an intermediate member or sleeve b provided at one end with slots f encircled by a split band tk forming a member of the clamping coupling. The ends of the band t<k> carry a forked head t<2>, to which the crank-handle u<1> is pivoted at u<10>, and a flange t<1> engaged by a projection u<3> on the crankhandle, so that the band tk clamps the slotted part of the sleeve b on the shaft g when the handle u<1> is turned clockwise. The unslotted part of the sleeve b is encircled by a band t<r> forming part of the reverse lock ; the ends of the band t<r> carry a forked head t<20> pivoted at u<20> to a member u<2> engaging a fixed member w, and a flange t<10> engaged by a projection u<30> on the member u<2>. A spring-pressed bolt y in the head t<20> engages ratchet recesses z in the sleeve b and prevents reverse rotation of the sleeve b by the shaft g. To enable the shaft g to be turned by the handle u<1> in a stepby-step manner, a plunger 2 sliding in a lug 4 on the band t<r> can be pushed into engagement with a toothed wheel 1 on the shaft g ; the plunger 2 is held in engagement with the wheel teeth by the side pressure transmitted from the shaft g when the handle u<1> is turned counterclockwise and is released by a spring 3 when the handle is again turned in a clockwise direction to rotate the shaft g. In modifications, (1) two concentric sleeves b are each engaged by a looking band such as t<r> ; (2) the locking band t<r> engages an extension of the band t<k> instead of directly engaging the sleeve b ; (3) the crank lever u<4>, Fig. 5, has a cam face bearing against a sliding fork t<4> adapted to engage the intermediate member t<5>, which is slotted and grips the shaft g when the lever u<4> is turned in the clockwise direction ; (4) two oppositely wound springs c, d, Fig. 6, serve as the clamping coupling and reverse lock. The spring c is wound on the slotted end of the sleeve b and the end c<1> of the spring is coiled on a pin k<1> on the handle ul, which is secured to a casing a. The spring d is coiled on the unslotted part of the sleeve b and its end d<1> engages a non-rotatable member e<1> having a squared or hexagonal end e<3> engaging a fixed member e<30>.

Title: Improvements in means for dynamically balancing a rotatable body and rotor
IPC: G01M1/22
Filed: 1944-04-06
Abstract: 587,353. Electric tests. AKTIEBOLAGET NORDISKA ARMATURFABRIKERNA. April 6, 1944, No. 6506. Convention date, Feb. 20, 1943. [Class 37] [Also in Groups XIX and XXXVIII] In analysing the unbalance of a rotor a first low alternating voltage is generated by microphonic means in accordance with vibrations of the rotor and a second low alternating voltage is generated by means responsive to the angular rotation of the rotor, this voltage being in phase with a pre-determined angular position of the rotor. The two voltages are separately amplified and are then connected to a rectifier bridge circuit including a D.C. galvanometer for indicating the phase difference of the amplified voltages. The bridge may be formed by vacuum tubes 26, 27, Fig. 3, with plates connected through resistors 30, 31 to a positive potential and cathodes connected to earth. The low generated voltages are connected through amplifiers 25, 29 to the control grids of the tubes. The second low voltage is generated by a photo-electric cell which is angularly adjustable relative to the microphone and the rotor. The cell is adjusted until the galvo 32 gives a zero reading indicating an angle of 90 degrees between the generated voltages and hence the position. of balance. Increase or reduction of the angle between the cell and microphone by 90 degrees from the adjusted position referred to produces a galvo reading proportional to the magnitude of the unbalance. The Specification as open to inspection under Sect. 91 describes a modified bridge circuit, Fig. 5 (Cancelled), wherein the amplified microphone voltage is connected to the primary of a transformer 33 and the amplified cell voltage is connected to the mid points of the secondary and a resistance 38. Rectifiers 34-37 are provided as shown. In a modification thereof rectifiers 36, 37 are omitted. This subject-matter does not appear in the Specification as accepted.
