Patent CA-1325037-C (CA)
Inventor: ARSENEAU REJEAN
IPC: G01R19/02
Filed: 1986-06-02
Granted: 1993-12-07
Abstract: TITLE RMS MEASURING APPARATUS FOR AC/DC VOLTAGES                         INVENTORS Rejean Arseneau John J. Zelle ABSTRACT A true RMS instrument using a multijunction thermal converter with two beaters automatically determines and displays the RMS value of an unknown voltage using two steps or modes.  In an AC mode, the unknown voltage is attenuated and balanced in the thermal converter with a DC voltage.  DC voltage is stored in digital form in a first latch.  In the DC mode, the unknown attenuated voltage is replaced by a chopped DC voltage which is then balanced with the DC voltage obtained in the AC mode.  The unknown voltage is determined by decoding the contents of a second latch which controls the chopped DC voltage.

Title: Signal communication capable of avoiding an audible reproduction of a sequency of information signals
Inventor: KAGE KOUZOU
IPC: H04B14/06
Filed: 1987-05-14
Granted: 1993-05-25
Abstract: Abstract of the Disclosure In a communication system for use in transmitting a sequence of information signals in addition to a sequence of digital voice signals subjected to adaptive delta modulation, the information signal sequence is modulated by a phase modulator (51) of the transmitter section (11a) into a phase modulated signal sequence and is combined with the digital signals by a combining circuit (15) into output signals.  The phase modulated signals might be sent through an ADM decoder (36) and a switch (44) of a receiver section (12a) to a loudspeaker (45) to be reproduced togeter with the digital voice signals.  However, such  phase modulated signals are not substantially audible for listeners because the phase modulated signals scarcely comprise a low frequency component.  The phase modulated signals may be binary Manchester code signals and may be either interposed in a quiescent time of the digital voice signals or placed at the end or beginning of each digital voice signal.

Abstract: Title Centrifugal Axle  speed Governor Abstract of the Invention A  reduction  gear  axle  apparatus  includes  a  differential gearing  assembly positioned  for  driving a  pair  of coaxially arranged driving axle shafts.  The apparatus includes a rotary input shaft disposed for coupling with a prime mover having a power modulating device.  A centrifugal speed control governor is  fixed to the input shaft,  and the governor  is operatively connected to the power modulating device for control thereof as a  function of axle shaft speed.   In one preferred form, the governor comprises a pair of plates with a plurality of slide weights circumferentially spaced about the plates.  One of the plates is fixed to the input shaft while the other is slideable thereon.

Title: Rectangular baler with dynamic testing of load cells and limp home mode
Inventor: STROSSER RICHARD P
IPC: B30B9/30
Filed: 1988-05-31
Granted: 1992-06-30
Abstract: Abstract of the Disclosure In a rectangular baler wherein right and left conrod load cells measure the force applied to plungers for compacting crop material, a microprocessor based control circuit monitors the loads registered by the load cells.  The microprocessor produces output signals to control the baler in accordance with the loads sensed by the cells.  On a stroke of the plunger, a one-quarter second interval is toiled after one cell registers a load.  If the second cell does not register a load within the interval it is assumed that it is faulty.  In order to permit continued operation of the baler, the output of the good cell is assumed to be, and is used by the microprocessor as if it were the output of the faulty cell.

Title: Modular dairy caser
Inventor: BUTTERLY EDWARD R JR
IPC: B65B5/06
Filed: 1988-10-05
Granted: 1991-10-22
Abstract: Abstract of the Disclosure High speed dairy casing methods and apparatus assemble columns of filled containers arriving on two infeed conveyors, transfer one, two or more columns to an assembly ramp adjoining each conveyor, and then sweep the assembled columns from the conveyor and the ramp together across the ramp to an adjacent loading zone for casing, leaving the assembly ramp free for assembling succeeding columns while case loading is proceeding.  Preferably two infeed conveyors deliver filled containers into two separate assembly zones with their ramps flanking a central loading zone, and a pusher with two extended positions propels each single column from its conveyor onto the assembly ramp, and then propels the final column with the assembled columns together across the ramp to the loading zone as the pusher advances to its remote extended position.  Programming of limit sensors and pusher controls, and re-positioning of adjustable guides and guide-plates adapts the modular casers of this invention to assemble many different sizes of containers, and to load them into one or two cases, utilizing either one or two infeed conveyors.
