Title: An improved electrical variable speed system or gear
IPC: F16H37/00
Filed: 1953-09-28
Abstract: 757,515. Motor driving arrangements. PATENTVERWERTUNG W. REIMERS GES. Sept. 28, 1953 [Sept. 29, 1952], No. 26574/53. Class 35. Relates to a variable speed gear drive comprising two motors, at least one being of variable speed type, clutches being provided to permit one motor taking over the drive from the other and the ratios can be so selected that the two parts of a clutch can be rotated in synchronism at the instant of change-over. As shown in Fig. 2, the variable speed motor 1 can be coupled directly to the output shaft 5 by clutch 15, or can drive shaft 5 through gears 13, 14, 19, 18 when clutches 16 and 20 are engaged but between these two speed ranges the constant speed motor 2 can take over through clutch 21 and gears 18, 19, clutch 15 being disengaged. After the second speed range of the drive with motor 1 the motor 2 can again take over, this time through gears 23, 24, the clutch 22 being energized while a third speed range can be obtained from motor 1 through gears 13, 14, 24 and 23, clutches 16, 21 and 22. If two speed ranges only are required, two clutches and two pairs of gears only need be employed, and if desired both motors may be of variable speed type.

Title: Improvements relating to misaligning belt drives
IPC: F16H7/02
Filed: 1931-09-24
Abstract: 383,355. Utilizing movements of vehicles. ALLIS - CHALMERS MANUFACTURING CO., 1126, South 70th Street, Milwaukee, Wisconsin, U.S.A.-(Assignees of Dahms, A. A. ; 7409, North Damen Avenue, Chicago, and Knudsen, T. C. ; 2113, North 55th Street, Milwaukee, Winconsin, both in U.S.A.) Sept. 24, 1931, No. 26651. Convention date, June 3. [Class 103 (iii).] Relates to belt gearing, particularly for driving dynamos, compressors, ventilators, refrigerators, &c. for Pullman or other railway vehicle axles, or for driving the axles from electromotors, in which the pulley grooves are liable to misalignment due to the swinging or axial movement of one of the pulleys. As shown, a dynamo 4 is pivoted upon the car body and spring-biased to tension the belts 7, which engage a pulley 9 on the armature shaft and a two-part pulley 8 on the truck axle 3. To prevent torsion of the belts, they engage deeply in the pulley grooves, as shown in Fig. 4, the groove walls beyond the outer faces of the belts being slightly curved or straight in section. The belts are preferably endless, so as to avoid joints into which water can penetrate, and are of hard non-tacky material such as of rubber-covered cord and fabric. As the belt-runs enclose the bar 6 of the truck, it is necessary, in order that the endless belts can be placed in position, to gap the bar at 21 and bridge the gap by a plate 22.

Title: A process for melting a rod of polycrystalline material zone-by-zone
IPC: C30B13/28
Filed: 1965-06-23
Abstract: A thin crystalline seed is joined to the tapered end of a thick polycrystalline rod of silicon by means of a pancake induction coil and a molten zone is passed through the rod from the joint by means of a cylindrical induction coil.  The rod is maintained vertical with the tapered end at the top or bottom during the process.

Patent GB-1291398-A (GB)
Title: Improvements in or relating to methods of measuring crosstalk between transmission lines
IPC: H04B3/487
Filed: 1971-04-19
Abstract: 1291398 Crosstalk measuring SIEMENS A G 19 April 1971 [10 April 1970] 26705/71 Heading G1U To measure the crosstalk in a line 8 from a line 2, each line is followed by a mixer 10, 3, a bandpass filter 11, 4, an amplifier 12, 5, a detector 13, 6 and a meter 14, 7, and the arrangement is characterized in that both mixers 10, 3 receive signals from a common local oscillator 15, which in operation is manually tuned so that a maximum reading is produced on meter 7 in response to a signal from a source 1. Meter 14 then indicates the magnitude of the signal induced in line 8. The use of a common oscillator ensures that the crosstalk measuring chain 10, 11 ..., 14, is accurately tuned to the signal source 1, and obviates any tuning difficulty that might arise if line 8 is noisy. In a first modification Fig.2 (not shown) two local oscillators are used, that for mixer 10 being locked to that for mixer 3. In a second modification, Fig. 3 the two intermediate frequency signals from amplifiers 5 and 12 are themselves mixed 19, to provide a further intermediate signal of zero frequency, the D.C. in which is extracted by filtering 20, and then displayed. In a third modification Fig. 4 (not shown) the meter 7 is omitted and the signal that would have been displayed is used to tune the local oscillator 15 automatically. In a fourth modification Fig. 5 the local oscillator is tuned automatically, as in the third modification, the outputs from the two amplifiers 5 and 12 are applied to a quotient forming device 26, and the resulting signal is displayed on a c.r.t. as an ordinate against an absica proportional to frequency. The signal source 1 may then be swept to provide a complete frequency/crosstalk characteristic.

A method cf feeding a sheet from a stack comprises positioning the stack of sheets on a rigid platform pivoted about an axis which is transverse to the feeding direction so that the centre of gravity of the stack lies to one side of the pivot axis whereby the weight of the stack urges the upper surface of the top sheet into engagement with a sheet-feed means positioned above the stack on the opposite side of the pivot axis, and operating the feed means. Fig. 2 is a side view of a sheet-feeding device in which a substantially rigid container 9 is removably rested on a fulcrum edge 30, and contains a stack 20 of sheets; the top sheet 26 has a part of its surface exposed and the weight of the stack causes each sheet 26, in turn, to be engaged by friction rollers 32 having an axis 31; these rollers can be operated to rotate in the direction of arrow 33 and feed the sheets in direction S. Tongues 41 formed in the fulcrum edge 30 are engageable with slots (42) in the bottom wall (10) of the container 9 (Fig. 1, not shown) and the container 9 and the stack of sheets may together form an interchangeable cartridge 8.
