Title: Improvements in or relating to miniature direct current motors
Inventor: SCHLENKER WALTER
IPC: H02K29/12
Filed: 1961-06-12
Abstract: 945,099. Electric motors. SIEMENS & HALSKE A.G. June 12, 1961, No. 21128/61. Heading H2A. A D.C. motor comprises a magnetized rotor control section which produces impulses in an axial stator coil, the impulses being amplified and applied to the axial coil of a second stator to cause an associated rotor driving section to rotate. In the motor shown the rotor driving section comprises a soft iron core 13 (Fig. 6) arranged between two 3-armed members 11 and 12 while the control section has a magnetized core 10 to induce magnetic poles in the members 8 and 9 as shown. Each rotor section co-operates with a respective stator comprising laminations having the shape shown in Fig. 3. The driving stator is formed from two sets of laminations 5b, 6b and 5c, 6c (Fig. 5), a soft iron ring 7 and winding 2 while the other stator comprises similar members 5, 6, 5a, 6a, 19 and 3. The driving stator winding 2 is arranged in the normally conducting output circuit of a two stage transistor amplifier (Fig. 7, not shown) and the stator coil current on connecting the motor to the supply causes the rotor to commence turning. After about a sixth of a turn the magnetized control rotor 10 induces a voltage in the control stator winding 3 which causes the transistor to be cut-off, but the rotor continues to be driven by the magnetized control rotor arms being drawn to the next stator pole until the transistor is again rendered conducting and the driving stator again becomes operative. The poles of the stator have reduced sections g, f, e (Fig. 3) over half their width, as shown at C-D, so that when the motor is stationary the rotor takes up a position in which the magnetized rotor arms are opposite the full section of the stator and subsequent energization of the motor will cause it to start and to rotate in the direction shown in Fig. 3. A magnetic coupling 16 (Fig. 5) in the output shaft permits relative rotation between the final output shaft and the rotor during overload and so prevents the rotor " sticking." A further transistor may be added to the circuit so that the output transistor is controlled during both its on and off conditions (Fig. 8, not shown). Starting may be effected by wholly mechanical means or by a device operated by the rotor control switch and mechanically coupled to the rotor. The control rotor may be magnetized by such that alternate arms are of opposite polarity and gearing may be interposed between the two rotors. In addition they may have different numbers of poles.

Title: Improvements in or relating to a combine harvester
IPC: A01D34/24
Filed: 1965-05-20
Abstract: 1,113,334. Combine harvesters. TEXAS INDUSTRIES Inc. 20 May, 1965 [3 June, 1964], No. 21511/65. Heading A1F. A combine harvester includes a mowing table which comprises a mowing mechanism having at least one transversely extending portion, the or each portion being pivotable with respect to an elevator housing to match unevennesses of the ground and having a pivotal axis which is substantially horizontally parallel to, but spaced from, the coincident longitudinal vertical planes of the mowing table and the harvester. The illustrated combine harvester comprises a header including two mowing portions 4 each pivotable about a horizontal axis afforded by pins 14, 15 and further comprises hydraulically operated means for controlling the height of the header and for raising and lowering portions 4, reels 39 and skids 51. A feeler 58, positioned under crop divider 63A, actuates a valve 108 upon encountering undulations in the ground which valve controls flow of liquid to or from cylinders 104 thus to retain the header at a constant height. This automatic control is terminated upon movement of lever 114 to the left of the position of Fig. 6 since a control valve (not shown) is closed thereby preventing flow of liquid from the valve 108 to reservoir 111. The lever simultaneously controls a valve 119, which is identical to the valve 108, and movement of the lever actuates the valve 119 thus to allow liquid to flow from pump 111A to the cylinders 104 via pipes 127, thus raising the header. A cam 117, which forms a part of the lever, is so shaped that when the lever is positioned in a recess 115 flow of liquid to the cylinders is interrupted; thus the header can be held at a desired height. The header is raised when the lever is positioned to either side of the recess 115, and lowered when the lever engages an element 115A. Raising and lowering of the portions 4, reels 39, and skids 51 is effected by pairs of cylinders, each pair being controlled by a valve identical with valve 108, the valves being in communication with the pump and reservoir. Gas cylinders (145) (Fig. 8, not shown) are in communication with the cylinders which raise and lower the portions 4, and thus those portions have resilient movement. In a further embodiment there is provided a header having a mowing bar pivoted at one end and connected to the mowing platform throughout its length by means of a resilient strip.
