Title: Dc motor controller
Inventor: PARK CHAN H
IPC: H02P7/29
Filed: 1992-01-29
Abstract: ABSTRACT       A DC motor controller for use with a battery powered DC motor operatively positioned in a vehicle is disclosed. A power source-watch dog circuit 2 monitors a micro computer 8 and  decreases  the  battery  supplied  voltage  to  below  a predetermined voltage.  A key switch input circuit 3 receives a switch-on signal generated by a key switch and outputs a signal to the power source-watch dog circuit 2 to initiate electrical power output from the battery 1 to the micro computer 8.  A pedal input circuit 4, which includes a pedal for  varying  electrical  resistance,  converts  the  varied resistance into an analog signal and outputs the analog signal to the micro computer 8.   The micro computer converts the analog signal to a digital signal and outputs the digital signal.  A D/A converter converts the digital signal outputted by the micro computer into an analog signal and outputs the analog signal.  A pulsewidth modulator 10 modulates the analog signal and outputs the modulated signal.  A gate output circuit 11 generates a logic signal having a "high" or a "low" level according to the modulated signal outputted by the pulsewidth modulator 10 and outputs the logic signal to a motor driver 16 which operates the DC motor.  A battery voltage sensor 7 senses the voltage of the battery 1 and outputs a battery voltage sensor signal to the micro computer 8.  A temperature sensor 13 senses the temperature of the motor driver and outputs a temperature sensor signal to the micro computer 8.  An output current sensor circuit 12 senses current flowing through the motor driver 16 and outputs a current sensor signal to the micro computer 8.   A vehicle direction changing sensor 6 prevents an overload of the DC motor 17 by sensing an abrupt change in the direction the vehicle is being driven and outputs a vehicle  direction  changing  sensor signal  to  the micro computer 8.

Title: Animal evisceration
Inventor: BUHOT JOHN W
IPC: A22B5/06
Filed: 1992-06-18
Abstract: A process of eviscerating an inverted animal carcass (10) inclined at 35· to 40· includes pushing the viscera (30) comprising both the thoracic viscera (31) and abdominal viscera (32) in a direction (B) from the cranial end (11) of the carcass (10) towards the caudal end (12) so as to pass between the hind legs (13) and fall from the carcass. Connecting tissues including the aorta (35) and external iliac arteries (36) are partially severed prior to pushing the viscera from the carcass so that the viscera detaches completely from the carcass after being pushed between the hind legs (13). The diaphragm (25) may be pierced at its periphery so that the force of the pushing operation causes the diaphragm to tear around its peripheral edges from the walls of the thoracic cavity. The pubic symphysis (60) is split before the pushing operation whereby the viscera (30) can pass both above and below and through the split in the pubic symphysis (60). Alternatively, the pubic symphysis (60) need not be split prior to the pushing operation whereby the viscera (30) travels over the pubic symphysis (60).  A pushing member (41) commences to push on the thoracic viscera (31) at about the fifth rib and travels at 0.5 to 0.6 metres per second.
