Abstract: 1,098,686. Assembling dynamo-electric machines. GENERAL ELECTRIC CO. Sept. 14, 1966 [Oct. 22, 1965], No. 40987/66. Heading B3A. [Also in Division H2] An electric motor, including a stator core 12 and a magnetic rotor core mounted on a shaft 17, is assembled by fastening the stator and the rotor in a fixed relation, mounting thrust transmitting members 27, 28 on the shaft 17, at least one of the members being spaced from the rotor, sliding bearing means 50 on to the shaft, each bearing means being fixed to a motor housing 49, securing the housings to the stator, releasing the stator and the rotor for relative rotation and moving at least one of the thrust members 27, 28 along the shaft towards the rotor to provide a desired degree of axial movement of the shaft in the housing. In one embodiment the stator and rotor are fixed by shims and the bearing members are made of plastics material, e.g. nylon, and one is mounted on the shaft 17 in abutment with the end face 21 of the rotor whereas the other member 28 is mounted on the shaft and spaced from the end face 22 of the rotor by a spring clamp 36. Alternatively, the member 28 can be spaced from the face 22 by a cylindrical member (41) with pins (44) which abut the face 22, Figs. 2 and 3 (not shown). End frames 47, 48 of light non-magnetic material, e.g. aluminium, with bearings 50 are then mounted on the shaft 17 with the wall 53 of each bearing abutting the thrust members 27, 28. The assembly is mounted on a supporting frame 56 with legs 58, 59 biased towards each other. The legs support the motor parts on knife edges 62, 63, see also Fig. 5 (not shown), to allow the frames 47, 48 to be pivotally moved to bring the edges 67, 68 into contact with the stator to which they are bonded by a thermosetting organic resin 70. The shims are then removed to allow relative rotation between the stator and the rotor and the spring 36 removed. The thrust member 28 is then moved along the shaft 17 into abutment with the end face 22 of the rotor by lightly tapping the shaft on the left-hand end (as viewed in Fig. 4), causing the bearing 50 to abut the member 28 as the shaft is moved rightwards. Both members 27, 28 are now in abutment with the rotor and the desired degree of axial movement of the rotor is achieved. In an alternative embodiment, Figs. 8-10, both members 27, 28 are spaced from snap rings 78, 79 during assembly and are moved into engagement with the rings by lightly tapping the shaft on the left- and right-hand side.

Abstract: 1306482 Reservoir applicators; carpet cleaners LEIFHEIT INTERNATIONAL GUNTER LEIFHEIT KG 9 Sept 1971 [12 Sept 1970] 42127/71 Headings A4K and A4F In a carpet cleaner, liquid cleaning agent passes from a container 14 via a trough-shaped distributor 56 to a foam producing roller 15 in contact with two further rollers 16, 17 such that the material of the rollers is partially compressed and the cleaning agent is foamed when the rollers are rotated. A plate-like, rectangular float 28 which floats on the liquid is contained within the container, the float having on its upper side a channel 24 which is connected via a duct 45 with the distributor, the duct being closed by a flap 49. The duct is opened on rotation of rollers 21 which guide the cleaner along the carpet and which are connected to bearings (54) Fig.2 (not shown) on either side of the flap. During reciprocating movement of the cleaner over a carpet, the differences in the mass inertia of the cleaning liquid and the float 28, cause the element to become immersed in the liquid or the liquid to wash over the float such that part of the liquid passes into the channel 24, through the duct 45 and into the distributor 56. The float 28 may be lifted away from the surface of the liquid by a framework 33 positioned below the float and having a laterally projecting stud (37), Fig.3 (not shown) which bears against a helical cam surface (38) on a cylindrical member inserted in the charging orifice of the container and rotatable from outside the container. The subject matter is identical with that of Specification 1306483, the claims of which relate to the discharge duct of the container being provided in the float.

Abstract: 1486586 Controlling DC motors MEIDENSHA KK 2 Oct 1974 [9 Oct 1973] 42764/74 Heading H2J [Also in Division H3] A chopper, e.g. for controlling a D.C. motor, comprises a first switching element such as thyristor 10 for periodically pulsing current from a D.C. source 20 through a load, such as motor 22, and a turn-off circuit comprising a series resonant circuit 14, 18 with a second switching element such as thyristor 32 connected without intervening switching components across the inductor 18 and arranged to be turned on immediately at the end of the half cycle following the turn on the first element 10. As described, when switch 92 is closed a capacitor 46 is charged from a constant voltage source across the Zener diode 36 via transistor 44 at a rate determined by potentiometer 54 until the programmable imijunetion transistor PUT 48 breaks down when the main thyristor 10 is turned on, allowing a pulse of current to flow in the armature 24 and field 26 of the D.C. motor 22. Transistor 66 becomes non-conductive at the end of the pulse, allowing capacitor 64 to charge via resistor 62 until PUT 72 breaks down, giving a pulse via transformer 81 which turns on the oommutating thyristor 32. The charge on capacitor 14 is reversed when the main thyristor 10 is turned on and the commutating thyristor 32 is arranged to be turned on at the end of the first half cycle of the oscillation of the series resonant circuit 14, 18. This applies the reverse voltage across capacitor 14 across the main thyristor 10 so as to turn off the main thyistor. The average current in the motor 22 is thus dependent on the interval between the turning off of thyristor 10 and the next turning on pulse from PUT 48, which interval is adjustable at 54. Alternatively, the commutating thyristor 32 may be turned on by means of a zero current detector connected in series with the resonant circuit 14, 18. The Specification explains that when the inductor 18 is short-circuited, a resonant turn off pulse is produced at a frequency determined by capacitor 14 and stray inductance. In Fig. 11 (not shown) the primary of a transformer is connected between the freewheeling diode 28 and the motor 22, the secondary forming inductor 18. In Fig. 8 (not shown), the capacitor 14 is connected on the anode side of thyristor 10.
