Abstract: PASTY PRODUCT DISPENSER HAVING COMBINATION ACTUATOR AND OUTLET VALVE          Abstract The actuating lever of the dispenser has a rigid valve flap integral therewith which covers the spout outlet to close the same when the actu-ating lever is in its normal, undepressed position but which then lifts off the outlet to open the same when the lever is depressed in a pumping stroke.  One embodiment employs a reciprocable pumping piston at one end of the dispenser body and a free-floating take-up piston at the opposite end of the body which responds to the evacuation of material within the pump chamber to take up the space otherwise occupied by the evacuated product. Another embodiment utilizes a pumping piston which starts at the lower end of the dispenser body and is progressively drawn up toward the opposite end during successive pumping strokes by a rod connec-ted to the actuating lever.

Abstract: Abstract A frequency and phase comparator circuit for determining the frequency difference between a reference signal of a known frequency and a variable signal of unknown frequency.  The subject circuit monitors the two signals and detects the occurrence of phase shifts between the two signals.  In particular, this circuit detects phase shifts of 180 degrees and 360 degrees and records a full slip indication with each occurrence of a 360 degree phase shift.  These phase shifts indicate that at some point in time during transmission, the two signals were out of phase and not of exact frequency.  In addition, the subject circuit provides a direction of drift indication with each 180 degree shift.  These direction indications are output following a 360 degree phase shift or full slip and are determinative of the relative frequencies of the two signals by designating whether the frequency of the variable signal is higher or lower than that of the reference signal over the duration of the full slip. Appropriate adjustments may then be rendered to adjust the frequencies.

Abstract: ABSTRACT OF THE DISCLOSURE               An electrochemical detection cell which includes, in the order named, a stack of components constituted by a first membrane, an electrode carrier having reference and counter electrodes thereon, a membrane support, an electrode carrier having a sensing electrode thereon, and a permselective membrane Whatman filter papers are positioned between the sensing electrode and both the counter electrode and reference electrode, these being positionable in a central rectangular opening of the membrane support.  The cell allows air or gas ambient to address the membranes and effects application of an electro-lyte to space between the electrodes by, for example, a wick which extends between an electrolyte-containing reservoir and the Whatman filter papers.  A system for detecting a gaseous agent uses the aforementioned detection cell coupled with circuitry capable of applying a fixed DC voltage bias to the reference electrode and superimposing a train of DC voltage pulses on the fixed bias. Further circuitry is coupled to and responsive to signals from the sensing electrode.          This circuitry determines the difference between the sensing electrode signal at the end of each pulse minus that just before each pulse.  The difference is proportional to the concentration of the test gas in the atmosphere adjacent to the sensor, and is a more specific and sensitive indication of the test gas concentration than prior art sensors.

Abstract: ABSTRACT OF THE DISCLOSURE Fluid springs are frequently used for assisting the movement of a movable construction unit, e.g. a boot lid with respect to a stationary construction unit, e.g. a motor car frame.  In view of facilitating the closing operation of the boot lid, the pressure in the fluid spring is sometimes selected such that the spring cannot fully overcome the gravitational forces acting onto the boot lid.  In such cases the spring cannot fulfil the function of maintaining the boot lid in the upper terminal, ie. the fully opened position without additional provision. In order to enable the spring to maintain the boot lid in the upper terminal position, the spring is constructed such that in the outer terminal position of the piston rod with respect to the cylinder as increased resistance is expected by the spring against pushing the piston rod inwards of the cylinder.  A simple and economic hydraulic circuit is proposed in view of achieving such increased resistance.
