Abstract: A DOUBLE LEVEL TILLER PLANTER ABSTRACT OF THE DISCLOSURE    A double level tiller planter is provided with a separate pair of tiller wings for the fertilizer introducing section and for the seed planting section.  The fertilizer introducing section is ahead of the planting section and is disposed at a level below that of the planting section.  Both the fertilizer and the seed planting sections are provided with a discharge conduit extending along generally the entire length of the trailing edges of the respective wings to improve the uniformity of distribution of the fertilizer and of the seed while also improving the formation of an intermediate layer of soil between the seeds and the fertilizer, to avoid direct contact between the two.

Abstract: TWIN TOWER ASSEMBLY FOR DECONTAMINATING COMPRESSED GAS   Abstract of the Disclosure A twin tower assembly for decontaminating compressed gas, each tower having inlet, outlet, drain and solenoid valves of which the inlet and drain valves are separately connected dir-ectly to the solenoid valve and actuated respectively to close and open by actuating gas supplied and exhausted through the tower's solenoid valve, the towers by alternate energizing of their solenoid valves under timer control and actuation of their inlet and drain valves each normally alternating between decon-taminating and regenerating cycles and together alternating in their decontaminating cycles for supplying a continuous output of decontaminated gas, the inlet and drain valves of each tower being so relatively constructed that actuating gas supplied at the same pressure at the solenoid valve exerts a greater force differential for closing the inlet valve than for opening the drain valve and ensures that in cycling the inlet valve will close before opening and open after closing of the drain valve.  Passage-connected outlet chambers in the towers enable each tower during a decon-taminating cycle to supply decontaminated regenerating gas to the other tower at a flow rate and reduced pressure predetermined by the size of a restricted orifice in the connecting passage and each tower removably houses in advance of its outlet chamber a canister containing and shippable loaded with a particulate desic-cant and mounting upstream of the desiccant an oil coalescer.

Abstract: WEIGHING APPARATUS AND METHOD        ABSTRACT OF THE DISCLOSURE         An  electronic weighing  apparatus  and method  is dis-closed which enables the counting of an unknown quantity of items or samples such as currency, coupons, coins or similar items of a nominally uniform weight.   The apparatus includes an electronic scale which provides a signal representative of the weight of an unknown quantity of items, a microprocessor which stores a repre-sentative unit weight of the items being counted and calculates an item count, and a display for providing an output representing the  running  count  or  other  value  representative of  the  items being weighed.   An accurate count of the  items  is obtained by placing items on or removing items from the scale in incremental groups such that the net weight of any incremental group of items must have a stable net weight equal to or below a predetermined threshold weight before the count  is made.  If any  incremental group has a net weight which exceeds the threshold weight, items must be  removed/added until  the number of  items  in  the group produces a net weight equal to or below the preset threshold and allows counting to continue.  The apparatus automatically accumu-lates the total count made in a number of successive weighments by incrementing  a memory  device  automatically when  the  scale weight reading returns to or below zero.  The weighing apparatus may  also  be  constructed  to  automatically  sequence  and  count through  a plurality  of groups  of  different  items  to minimize operator  intervention.   The apparatus may additionally be con-structed and operated to produce automatic verification of prede-termined quantities of items without operator intervention.

Abstract: Abstract A low Q ring laser gyro-dither motor assembly which is responsive to a wide range of frequency com-ponents of a drive signal having a randomly varying frequency such that the dither imparted to the gyro is frequency modulated by the drive.  The frequency mod-ulated dither varies the lock-in rate of the gyro as a function of the random drive signal to eliminate errors in the gyro output due to lock-in.  The drive signal may be random in frequency only or random in both frequency and amplitude to provide the frequency modulation.  Fixed frequency modulation may also be employed.  The low Q assembly need not be driven at the natural frequency thereof so that a common drive circuit may be employed for a plurality of low Q gyro-dither motor assemblies forming an instrument cluster.

Abstract: Abstract Method And Apparatus For Torgue Control Of An Internal Combustion Engine As A Function Of Exhaust Smoke Level A method and apparatus are provided for controlling the torque or fuel quantity limit to an internal combustion engine such as a diesel engine, at least partly as a function of the sensed level of smoke in the exhaust gas stream of the engine.  An open-loop preliminary fuel quantity limit signal is provided as a function of engine speed.  The actual smoke level is compared with a smoke limit value for the particular operating condition, and an error signal indicates the sense and possibly the magnitude of any difference.  The error signal is the basis of a compensating signal which is added to the open-loop preliminary fuel quantity limit signal such that the resulting fuel quantity limit signal provides for maximum torque without exceeding the smoke limit. The smoke level is obtained by a direct measurement of the particulate level or the like in the exhaust gas stream.  An alarm may be provided for indicating when the actual smoke level exceeds some threshold relative to the smoke limit.
