Abstract: 929,065. Hay-conditioning machines. INTERNATIONAL HARVESTER CO. March 27, 1961 [Aug. 9, 1960], No. 11047/61. Class 59. [Also in Group VIII] The crushing rolls of a hay-conditioning machine comprise a plurality of sections of moulded fibre-impregnated elastomer material keyed to a shaft and means for compacting them axially in end-to-end relationship, each section having a length at least equal to twice its diameter. As shown, the lower roll 8 is smaller in diameter than the roll 12 above and is supported by bearings 9, 10 in a frame 2 of the machine in close proximity to the ground, the upper roll 12 being capable of being loaded against the lower roll 8 through mechanism 39. The roll 8 as shown consists of a number of cylindrical sections 14, 15 which are pressed together and secured on a square-sectioned shaft 7 with end caps 21 and pins 22, while the roll 12 consists of four frusto-conical sections 25, 28 which are similarly mounted on a shaft 32 between end caps 30 and are so tapered as to cause tapered gaps 38 to appear between the outer ends of the two rolls when these are in contact. The end caps of the two rolls press the sections axially together to an extent sufficient to eliminate the parting lines between adjacent sections. The roll sections have circumferentially-shaped helical grooves 35 spaced at 90 degrees. Further, instead of using a crowned roll in conjunction with a cylindrical roll as shown, both rolls may be of crowned formation.

Abstract: 1465369 Control of D.C. motors WESTING- HOUSE ELECTRIC CORP 18 March 1974 [30 March 1973] 11911/74 Heading H2J An electric vehicle is driven by a separatelyexcited D.C. motor whose armature (14), Fig. 2 (not shown), is supplied from a battery (16) through the normally-closed contacts 64 of relay 60, the current if for the motor field winding 18 being supplied by a controller 22 having an amplifier 40 receiving a motor current signal from a resistor 24 in the armature circuit, amplifiers 50, 52 whose gain is varied by adjustment of potentiometers 31, 33 coupled to the throttle foot pedal 28, a power amplifier 54 receiving the outputs of amplifiers 50, 52 and that from a potentiometer 46 used to set a minimum field voltage to protect against overspeed of the motor, and further potentiometers 42, 44, 48, the various throttle settings providing a family of torque-speed curves, Fig. 6 (not shown), whereby the motor may be operated as desired in the driving or regenerative braking mode. Relay coil 62 is in series with the winding 18 whereby, if the field current falls below a predetermined value, the contacts 64 open to disconnect the armature from the battery. Potentiometers 46, 48 are set to provide a base speed (full field voltage at zero throttle setting) for a particular armature supply voltage. The output voltage of controller 22 includes a portion providing feedback to control the motor torque when the throttle setting is increased to initiate field weakening, and a portion to provide feedback to give an approximately constant regenerative braking torque over a wide speed range for a given throttle setting. By connecting a torque converter between the motor and the vehicle wheels, the vehicle speed may be varied between zero and the base speed set for the motor, which is operated in essentially a constant torque mode for a given excitation or with a variable excitation and torque for a motor speed constant at the base value. In a modification, Fig. 5 (not shown), a tachometer (79) sensing the speed of the motor or a vehicle wheel provides a signal to the input of amplifier 52 through the contacts of a relay (49) responsive to armature current to respectively close or open if it is greater or less than zero. The addition of this speed signal provides, for the various throttle settings, torque-speed characteristics each having a variable torque constantspeed portion, Fig. 8 (not shown). Amplifier 54 may include thyristors and the control parameters determining the output of controller 22 are dependent on such considerations as maximum and minimum field voltage, maximum desired torque at base speed and maximum braking torque required at zero throttle setting.
