Abstract: ALTERNATING CURRENT DRIVEN LATCHING RELAY AND METHOD     OF OPERATION                ABSTRACT OF THE DISCLOSURE           An alternating current latching relay is provided which employs a latching-type, mechanically operated snap-action switch mechanism with a set of electric contacts that are selectively latched either in the open or closed condition in a snap-action manner upon successive actuations of the snap-action mechanism by suitable push rod means for initiating its operation.  At least one alternating current excited bender-type piezoelectric drive member has one end secured to a common base member with the latching-type snap-action switch mechanism and the remaining free end engaging the push rod means.  An alternating current electric excitation signal is directly applied to the piezoelectric plate elemnts of the bender-type drive member for mechanically vibrating the bender-type drive member in a manner such that its amplitude of vibration quickly builds up to a value where it repeatedly strikes the push rod means with sufficient force to selectively actuate the snap-action switch mechanism to the opposite one of its two operating conditions from that in which it originally was sat.  A tuning mass in the form of a slug element is secured to the end of the bender-type drive member to reduce the natural resonant frequency of vibration of the bender-type drive member to reduce the natural resonant frequency of vibration of the bender-type drive member to substantially the frequency of the alternating current excitation signal to thereby increase the amplitude of its vibrations to a maximu.  Additionally, the tuning mass increases the impulse delivered by the bender type drive member to the push rod for actuating the snap-action mechanism.

Abstract: INVENTORS:  MAX BR?NDLI and HANSUELI FELDMANN          INVENTION:  JOINT FOR A TRANSVERSELY SEPARATED VEHICLE                    ABSTRACT OF THE DISCLOSURE         This joint allows a drive member and a driven member of a transversely divided or separated vehicle to be deflected relative to each other about a virtual pivot axis which extends in a direction transversely to the vehicle.          The drive member and the driven member are connected on each side by a first support element which supports against forces acting parallel to the transverse and vertical axes of the drive member and by a second support element which supports against traction and braking forces.  Each first support element contains a support roll rotatably supported in a support at the driven member and guided in the longitudinal direction of the vehicle in a slide bracket arranged at the drive member.  Each second support element comprises a hinged link rotatably mounted about a respective transverse axis at the drive member and the driven member.  When travelling over changing slopes or gradients there results automatic matching of axle loads and torques at the drive wheel due to the deflection of the vehicle members.

Abstract: POLARIZATION-INSENSITIVE OPTICAL                 MULTIPLEXING APPARATUS                 Abstract of the Disclosure Polarization-insensitive optical multiplexing appar-atus for independently modulating perpendicularly polarized components of a collimated input beam includes a polarization beam splitter for receiving an input collimated beam which has arbitrarily polarized components, splitting the beam in-to the two components.  One of the components is rotated by a 1/2 wave plate so as to yield a polarized beam which is polarized in the same direction as the other beam.  The two polarized beams are then applied to a polarization sen-sitive interferometric multimode fiber optic switch and mod-ulator.  The output of the interferometric multimode fiber optic switch and modulator contains two beams, both polarized in the same direction. One of the beams is rotated ninety degrees by a 1/2 wave plate, and the two mutually perpendi-cularly polarized beams are then recombined by a polariza-tion beam splitter operated in reverse to yield an output beam containing mutually perpendicular components.

Abstract: ABSTRACT       The present invention is directed to compositions containing drugs having a sedative,  analgesic,  or anesthetic effect.   A drug capable of absorption through mucosal tissues is incorporated into a candy matrix, which is then advantageously formed into a lollipop.          The drug rapidly enters the patient's bloodstream as the lollipop is sucked.  When sedating or anesthetizing the patient,  the physician can observe the patient's condition and remove the lollipop when it has  had a  desired  effect  on  the  patient.    Alternatively,  the physician can alter placement of the lollipop to slow the rate of the drug release for absorption  into  the  patient's  system.    An analgesic-containing lollipop can be self-administered by a patient in response to his own subjective experience of pain and to the patient's susceptibility to the particular drug utilized.

Abstract: ABSTRACT OF THE DISCLOSURE An apparatus and method for manipulating the temperature and pressure of the hydrocarbon phase in an acid settler vessel associated with a catalytic alkylation process and apparatus, wherein the hydrocarbon phase in the acid settler vessel is regulated by controlling the amount of rerun catalyst stream entering the hydrocarbon phase of the acid settler vessel. In response to a detected temperature or pressure of the hydrocarbon phase above a set point, the flow of rerun catalyst stream to the hydrocarbon phase of the acid settler vessel is decreased. This decrease in flow to the hydrocarbon phase may be accompanied by an increase in flow of rerun catalyst vapor to the catalyst phase of the acid settler vessel.

Abstract: CHEMICAL HEAT PUMP UTILIZING CLATHRATE FORMATION REACTION     ABSTRACT OF THE DISCLOSURE      A chemical heat pump utilizing a hydrating agent as the working fluid is disclosed.  The clathrate formation reaction of a hydrating agent such as flon 31 or 22 is used as one of the two equilibrium reactions of the working fluid so that heat can be pumped up across a temperature difference greater than that between the two heat sources.  The heat pump comprises four container means in which reactions take place so that the regeneration process can be effected simultaneously with the heating or refrigerating process in which the temperature of the thermal medium to be utilized, e.g., water, is raised or lowered.  The working fluid flows either in continuous one-directional circulation through the four container means, or in alternate directions therebetween.          In addition to the two heat sources at two different temperatures, such as waste heat and open air, the heat pump further comprises gas pipes which allow the free movement of the working fluid between the connected container means.

Abstract: ABSTRACT       A photoelectric touch input panel has a plurality of crossed light beams which are broken by an object, the position coordinates of which are identified as outputs.          Two spaced apart beam surfaces are provided, and the inter-relationship between the beams in the two planes is em-ployed to distinguish between interrupting objects on the basis of their size, attitude, and velocity characteris-tics.  The number of beams broken in any beam plane is counted to determined the relative size of the object, or to determine the center line of the interrupting object.          The beams in any beam plane are selected in accordance with the relative significance of the various beams, and interrupted beams are pulsed more rapidly than non-interrupted beams.  The light-emitting devices of the various beam planes are constructed as an integral unit.          The control system of the touch input panel is adapted for use in monitoring the size, shape, and activity of objects within a space defined by plural beam planes, independently of the touch input panel.
