Abstract: ABSTRACT     A one-way flow check valve is placed over an air inlet conduit to a hydrotherapy unit to prevent back flows of air and water up through and out of the conduit when the hydrotherapy nozzle outlet is blocked. A body of the valve contains a vertically-movable float which normally rests upon s retainer ring in a downward, air suction position. The float is raised upwardly and against a valve seat upon reverse flow of air and water. The light weight, buoyant construction of the float, as a hollow plastic member with top and side walls, allows the valve to shut off reverse flows of water whether fast or slow moving and to respond also to fast reverse flows of air ahead of a rising column of water. A retainer ring with float abutment pins retains the float in the body removably for cleaning the valve surfaces.

Abstract: D-20,386 FREQUENCY DEVIATION MEASURING AND ADJUSTING SYSTEM   by Maurice C. Harp and Terry R. Seaver ABSTRACT OF THE DISCLOSURE     A calibrated unipolar signal is used to deviate a frequency modulator by a predetermined amount .DELTA.f from a carrier fc.  An automatic frequency control circuit operates to bring the carrier back on frequency and a meter connected in the control circuit will read this departure from normal.  During the test for correct deviation, a frequency shifter compensates for the predetermined frequency deviation and the meter would so indicate, i.e., would not change reading from that of carrier alone, if the deviation caused by the calibrated unipolar signal is equal to that incorporated in the frequency shifter.  If the reading does change, the modulation sensitivity of the frequency modulator is adjusted until the readings before test (using carrier only) are the same as those under test.

Abstract: A PUSH ROD ASSEMBLY                       ABSTRACT OF THE DISCLOSURE         A push rod assembly having a first section and a second section through which an input force is transmitted to an output member. The first section includes a cylindrical member with a bellows attached thereto.  The cylindrical member has a bore therein.          The second section includes a piston that is attached to a brake pedal by a pivot pin.  The piston divides the bore in the cylindrical member into a first chamber and a second chamber. The piston has a passage therethrough that connects the first chamber with the second chamber.  A valve located in the passage controls the communication of fluid from the first chamber to the second chamber.  A linkage member which extents into the bore in the cylindrical member is connected to a plate with a slot therein.  The pivot pin associated with the brake pedal extends through the slot to attach the plate to the brake petal.  In the rest position, the plate engages a stop and allows the pivot pin to move in the slot and bring the linkage member into engage-ment with the valve to allow free communication through the passage in the piston.  A switch member, responsive to movement of the brake pedal by an input force, allows a source of vacuum to evacuate air from the bellows to create a pressure differential therein with air in the surrounding environment.  The pressure differential causes the bellows to contract and thereby move the cylindrical member at a faster rate than the piston and move the valve away from the linkage to interrupt the fluid communication through the passage.  With fluid communication through the passage interrupted, a fluid lock is created in the first chamber.  Thereafter, the input force from the brake pedal is transmitted to the cylindrical member from the piston through the fluid in the first chamber.

Abstract: 1934-228a ABSTRACT OF THE DISCLOSURE              A growing tobacco stream is formed at the underside of a foraminous belt conveyor and is transported past two trimming devices to be converted into a rod-like filler which is thereupon draped into cigarette paper and severed into discrete plain cigarettes which are united with filter plugs to form filter cigarettes of unit length or double unit length.  The resistance of successive identical sections of the filler to axial and/or transverse flow of air therethrough is monitored, and the resulting signals are used to adjust the second trimming device when the monitored resistance deviates from a desired value. The envelopes of filter plugs on successive filter cigarettes are perforated by a laser which is adjustable by signals denoting deviations of the mass of tobacco per unit length of the filler from a preselected value, deviations of the resistance of filter plugs to axial flow of air therethrough from a preselected value and/or deviations of the permeability of cigarette paper from a preselected value.  This insures that the column of gaseous fluid which enters the mouth of a smoker contains a mixture of tobacco smoke and of a predetermined quantity of cool atmospheric air.

Abstract: ABSTRACT OF THE DISCLOSURE         A breakerless distributor for an internal combustion engine ignition system in which a number of light emitting diodes (LEDs) equal to the number of engine cylinders are connected in series for simultaneous energization by the timing pulses.  A phototransistor arranged in spaced, con-fronting relationship to each LED is connected to a silicon controlled rectifier which triggers the energizing circuit for an individual spark plug each time the phototransistor is turned on by emissions from its  associated LED.  The LEDs and photo-transistors are arranged in concentric circles on a printed circuit board with the angular distance between pairs of LEDs and phototransistors equal to the firing angle.  A slot in the wall of a cup member mounted for rotation between the LEDs and phototransistors allows only one phototransistor, and therefore one spark plug, to be energized per timing pulse as the cup member is driven in synchronism with the rotation of the motor. Full timing advance can be accomodated even at small firing angles by increasing the angular width of the slot in the cup member.  For very small or irregular firing angles, additional pairs of LEDs and phototransistors are arranged in another pair of concentric circles  with a second slotted cup for controlling sequential turn on of the additional phototransistors.  As an alternative to placing the LEDs and phototransistors in con-centric circles, they may be arranged in axially displaced circles with an intervening slotted disc in place of the slotted cup.  Apparatus is also disclosed to prevent multiple spark plug firing due to radio frequency interference and for generating suitable firing pulses from a magnetic pickup at high speeds and small firing angles.

Abstract: ABSTRACT      A disposable product and a process for manufactu?-ing the disposable product on a flexible conveyor.  The disposable product has an absorbent core formed by sand-wiching a corrugated tissue between two separate feeds of fluffed pulp.  Upper and lower layers of wadding are pro-vided, the lower wadding being first folded around the absorbent core longitudinally and then an upper wadding is laid on top.  The upper and lower waddings are then roller crimped together and die cut and shaped and turned ninety degrees.  Thereafter, a water impervious sheet of material, such as polyethylene, is provided with a glue line on its edges and is fed across the top wadding and wrapped about the top wadding, the core and partially overlying the lower wadding.  A sheet of non-woven material is then wrapped about the assembly and provided with a longitudinal strip or strips of pressue sensitive adhesive.  A release paper is applied over the adhesive to protect it prior to use. The lower layer of fluffed pulp is provided with recesses partially therethrough for accommodating subst?ntial dis-charges of material at a rate faster than absorption is possible so as to prevent leakage.  These recesses are formed by embossing so that the material beneath the recesses are substantially compressed.
