Granted: 1980-10-28
Abstract: CAM ACTUATED MULTIPLE CONTACT      SPRING SWITCH            Abstract of the Disclosure A switch is disclosed in which manual adjustment of a contact spring pileup is avoided by closely controlling the interaction between 1) the contact springs, 2) a movable actuator including a plurality of cam surfaces, each of which is associated with an individual contact spring, and 3) a frame for supporting the actuator.  This is achieved by molding a cam follower to one end portion and a mounting element to the other end portion of each contact spring.          The mounting elements of the contact springs are positioned in engagement with one another and are secured to the frame.          The mounting elements serve to orient the contact springs at a particular angle with respect to one another and accurately locate the contact springs and thereby the cam followers with respect to the cam surfaces of the actuator.          The cam followers in combination with the associated cam surfaces serve to locate and provide a predetermined bias to the contact springs.

Abstract: LIQUID DISPENSER LOCKING MEANS                  ABSTRACT OF THE DISCLOSURE           A liquid dispenser has relatively rotatable closure, sleeve and plunger members, the latter two being locked against reciprocation of the plunger member by a misalignment between ribs and grooves therebetween.  One of the grooves has a pair of upstanding pegs on opposite sides so as to not only avoid in-advertent alignment when the ribs and grooves are in a misaligned position, but to also permit the plunger and sleeve members to rotate together as the rib abuts against one or the other of the pegs when in a misaligned position.  A spacer element surrounding the plunger rod maintains the inlet valve in a closed position despite a slight separation between the plunger and sleeve members when rotated to the misaligned position.  Also, the closure mem-ber is adapted to be removed only with difficulty from the con-tainer on which it is affixed.

Abstract: ABSTRACT OF THE DISCLOSURE      A closed loop integral control system for the air/fuel management of an internal combustion engine is disclosed. An oxygen sensor positioned in the exhaust gas of the internal com-bustion engine is biased with a constant current source to provide a signal indicative of the oxygen content of the exhaust gas over a significant range of air/fuel ratios. The signal waveform from the sensor is compared to a threshold value  of a comparator to produce level changes in the comparator output depending on whether the output of the sensor is above or below the threshold.  An integrator, receiving these level changes as commands to increase or decrease the fuel pulse widths, controls the air/fuel ration of the engine in a limit cycle around a scheduled value.  By changing the current bias on the sensor and thus modifying the unbiased waveform of the sensor to intercept the threshold value at various points different average air/fuel ratios are obtainable from the system.  According to another feature of the invention, cruise detection circuitry determines when the engine is in a stable non-accelerating/decelerating mode and enables the current source to bias the sensor to produce a relatively lean air/fuel ratio from the system for an economical optimum cruising operation.

Abstract: ABSTRACT OF THE DISCLOSURE   A device for measuring acoustic properties and their changes in a sample of liquid, gas, plasma or solid.  A variable frequency source is applied to the sample by means of a transducer to produce sound waves within the sample. The application of the variable frequency source to the sample is periodically interrupted for a short duration.  Means are connected to the transducer for receiving the resulting acoustic signals during the interruptions for pro-ducing a control signal indicative of a difference in the frequency of the output of the bariable frequency source and the frequency of a mechanical resonant peak in the sample.  The control signal is applied to the variable frequency source to maintain its output frequency at the frequency of the mechanical resonant peak.  The change in frequency of the variable frequency source is indicative of the shift in frequency of the mechanical resonant peak and the amplitude of the acoustic signals is indicative of the attenuation of the acoustic signals in the sample.

Abstract: ARRANGEMENT FOR A PLANETARY DRIVE ASSEMBLY                Abstract of the Disclosure A drive assembly (20) has a planetary gear assembly (27), driven member (22), and first housing element (28).  The assembly (20) is, for example, part of a final drive (12) of a work vehicle (10) or pulley drive for a material handling system.  A first bearing element (30) supports the driven member (22) in rotat-able relationship relative to the housing element (28). A second bearing element (32) supports the housing element (28) in rotatable relationship relative to the gear assembly (27).  On the vehicle (10), gear reduc-tion taken inside of a tandem housing (14) has hereto-fore resulted in an overturning reaction force on the housing (14) which creates unequal wheel loads.  In the drive assembly (20), the first and second bearing elements (30,32) are positioned between the driven member (22) and housing element (28) and a ring gear element (40) of the gear assembly (27) and the housing element (28), respectively, to provide gear reduction substantially within and to substantially prevent the reaction force on the tandem housing (14).

Granted: 1982-11-16
Abstract: ABSTRACT: "Amplifier arrangement comprising two transistors"   The amplifier in accordance with the invention is symmetrical and comprises two transistors, whose emit-ters are connected to earth via two resistors of equal value.  The input signal is applied between the bases of the transistors and the output signal is available on the collectors of the transistors.  It is found that such an amplifier has an improved linearity up to an input voltage of 200 mV, if for the emitter resistor the relationship R ? 0.56 UT/ICO is satisfied, UT being the thermal voltage and ICO the collector quiescent current (in the absence of an input signal between the bases of the transistors).  The value of this resistor is very small (only approx. 14 ohms at a collector quiescent current of 1 mA), so that the slope is reduced only slightly by the emitter resistors and the sensitivity of the circuit is hardly affected thereby.
