Abstract: 1404043 Control of D.C. motors H Z TABOR 19 Oct 1972 [22 Oct 1971] 48250/72 Heading H2J [Also in Division B7] A variable speed electric drive system for high inertia load devices, such as vehicles or heavy machinery, comprises an electric motor drivingly connected to a flywheel and a variable torque converter coupled to the flywheel, the rated no-load speed of the motor being substantially equal to the maximum design speed of the flywheel and the rated full load speed of the motor drive being less than about 70% of the rated no-load speed of the motor drive. In one embodiment, Fig. 3, a D.C. compound-wound motor has an armature 3, a series field winding 4 and a shunt field winding 6 controlled by a resistor 7. Motor shaft 8 is coupled through a fixed ratio transmission 8<SP>1</SP> to a flywheel 9. Flywheel shaft 10 is connected to a clutch 11 coupled to a torque converter 14 controlled by a pedal 15 to drive vehicle wheels 19, 19<SP>1</SP> through a differential 17. The windings 4 and 6 are designed to provide a self-regulation of the motor substantially matching the speed regulation of the flywheel. When the flywheel rotates at maximum speed, the motor rotates at maximum speed and is unloaded, whereas when both rotate at minimum speed the motor is under full load accelerating the flywheel. A centrifugal switch 20 cuts out a resistor 5 when the motor speed approaches minimum design speed. In a modification, a D.C. electric motor 60, Fig. 6, is energized by a battery 62 connected to a shunt field coil 64 whose current is controlled by the conductivity of a transistor 66 depending on its bias determined by the values of resistances 70 and 68. This arrangement provides two components of field current, one component (resistance 70) being substantially constant and the other (resistance 68) varying with armature current to provide characteristics similar to a compound-wound D.C. motor.

Filed: 1974-11-20
Abstract: 1494497 Continuous ovens MONSANTO CO 20 Nov 1974 [21 Nov 1973] 50225/74 Heading F4B Apparatus for temperature-conditioning elongated moulded parts 50 comprises a heat transfer chamber 22 with an upper course 26 covered by panels 14 and a lower course 28 downwardly open to the surroundings. The upper course 26, Fig. 2, is divided by panels 38, containing heat transfer medium flow channels 40, into parallel paths 39 along which the parts are conveyed for temperature conditioning. The parts 50 are supported vertically in the paths 39 from bar assemblies 48 that are moved by endless double stranded chains 80 on each side of chamber 22 from a feed end 30 to a discharge end 32. The bar assemblies have stub shafts 90, Fig. 4, with roller followers 94 that run in guideways 88 on either side of chamber 22. Along the bar assemblies are part-supporting and rotating mechanisms 51, Figs. 3 and 4 with worm and pinion arrangements 128 and 64 driven by sprockets 132. Each bar assembly is indexed to the upper course 26 by cyclically rotating wheels 204 on either side of the apparatus at the end 30 which engage the stub shafts 90. The sprockets 132 engage the outer strands 87, Fig. 3, of the chains 80 and the bar assembly is carried forward until it contacts other bar assemblies in the upper course 26. At this point the bar assembly stops moving forward and the action of the chain 80 which continues to move forward rotates the sprockets 132 and hence the mechanisms 51 containing the parts 50 commence to rotate. Bar assemblies gather in line in the area 249 of the upper course 26 until they are sequentially released to the lower course 28 by metering wheels 135 and 140 that engage the stub shafts 90 of the bar assemblies. Parts 50 are supported by a guide member 169 as they move between the upper and lower courses and discs 100 of friction wheels 96, Fig. 7, engage the underside 102 of each bar assembly to prevent falling by gravity as they move from the upper to the lower course. A series of slide gates 164, Fig. 8, one for each path 39, and pneumatically operated to a predetermined pattern release the parts 50 from the bar assemblies as they arrive inverted in the lower course. The parts 50 fall into a hopper 163 which rotates about a shaft 288 at a speed which is synchronized with the metering wheels 135 and 140 and with the opening of the slide gates 164. Empty bar assemblies are moved by the chains 80 to an assembly position 251 at the end of the bottom course 28 from where they are indexed to the top course by the wheels 204. The metering wheels 135 and 140 are electrically synchronized via a micro-switch 214 with the wheels 204, to maintain the desired flow of bar assemblies through the apparatus. The switch 214 may be over ridden to alter the rate of feed to the chamber 22 at the charging end 30 relative to the rate of discharge from the end 32 to adjust the accumulation of bar assemblies in the area 249 of the chamber.

Abstract: 1352958 Portable power tool ROBERT BOSCH GmbH 1 Nov 1972 [2 Nov 1971] 50261/72 Heading B3C [Also in Divisions F2 and B4] A portable multi-speed power tool comprises a change-over gear including a selectively-operable clutch 67, 68, and an over-running clutch 44. The tool includes a split plastics shell 1, 2, which contains a commutator motor 5, whose shaft 13 has a fan 16 mounted thereon. A tool spindle 28 is adapted to be urged to the right, against a spring 35, Fig. 1, so that notches 38 formed on the end of a gear-wheel 37 fixed to the spindle coact with similar notches 39 formed on a bearing support 20, to produce a percussive action. This can only take place when a shift pin 24 is rotated by a knob 25 so that a ball 29 on the spindle enters a groove 26 in the shift pin. A further gear-wheel 40 is mounted on spindle 28, and grooves 42 formed in the bore 41, Fig. 4 (not shown) of the gear-wheel are engaged by spring- urged balls 44, to form the over-running clutch. An intermediate shaft 46 lies parallel to spindle 28 and shaft 13 and has a gear-wheel 49 rigidly secured thereto, which engages a pinion 23 formed on motor shaft 13. A still further gearwheel 50 is longitudinally displaceable on shaft 46 and is adapted to mesh with gear-wheel 37 on spindle 28. Gear-wheel 50 has a circumferential groove 53 into which a pin 65 is placed, so that when a handle 61 carrying the pin is rotated, the eccentric pin 65 moves gear 50 along shaft 46. The bore of gear-wheel 50 has two semi-cylindrical grooves 55 which are connected to an enlarged bore 56, so that spring urged balls 67 are urged into the grooves to drive the gearwheel, or into the bore 56 which arrangement provides the selectively operated clutch. In operation, pinion 23 drives gear-wheel 49 and shaft 46 so that a pinion 58 on the shaft drives tool spindle 28 through gear-wheel 40. When gear-wheel 50 is moved to the left, Fig. 2, it is driven by balls 67, and thus gear-wheel drives spindle 28 through gear-wheel 37 at a faster speed, and the drive between gear-wheel 40 and spindle 28 is disengaged.
