Abstract: Abstract of the Disclosure This invention relates to ornaments for installation in a string of lights and more particularly to ornaments which have lights and electrically energizable musical and/or motion produc-ing devices which cooperate to produce attractive sensory effects. Circuitry is provided for operating such devices in a safe and highly reliable manner, while being compact and readily and econo-mically manufacturable.  In one embodiment, an enhanced visual effect is produced by a rotating element driven through a gear reduction unit from a small electric motor.  In another embodi-ment, a music module is provided which includes a small speaker energized from an integrated circuit which generates musical tones.  In an ornament constructed in accordance with the invention, connectors are provided to connect input terminals of a bridge rectifier in a string of lamps while a lamp of the ornament is connected in series with a load device and to output terminals of the bridge rectifier, with protection means being provided for limiting voltages across the lamp and the load device, and to thereby protect against possible highly adverse consequences of open circuit conditions.  The connection of the lamp in the output circuit of the rectifier, in series with the load device, rather than in series with the input of the rectifier, is advantageous in connection with limiting voltages in the circuit and in permitting use of a lamp which does not need to match the lamps of the string.  Preferably, the voltage across the lamp is limited by a single Zener diode, only one diode being required since the cur-rent is unidirectional in the output circuit of the rectifier. The Zener diode across the lamp provides additional protection against burn-out and extends the life of the lamp, to provide further protection against open-circuit conditions.

Abstract: ABSTRACT OF THE DISCLOSURE         In a telecommunication system in which alternately circuit-switched and packet-switched information is trans-mitted in time-divided form between transmitter and receiver equipment, a system is described for mutliplexing telephony channels with static and dynamic capacity.  A static channel occupies a time slot in a fixed frame structure. The dynamic channels utilize idle time slots.  A status bit per time slot states whether the time slot is occupied or not. Equipment for transmitting circuit-switched information is combined with equipment for transmitting packet-switched information, such that a hybrid system is obtained which, under the control of a status bit, alternately transfers information from the resepctive equipment in response to the polarity of the status bit.  A circuit-switching memory is continuously scanned in a multiplexer.  Data words are stored in the memory, each word corresponding to a time slot, which in turn corresponds to an information channel in a TDM system.  A status bit of the mentioned kind is inserted in each data word.  For an occupied time slot in the memory, the word from the memory is transmitted to a circuit-switching receiver via a line and a demultiplexer. For an idle  time slot in the memory the word which is first in the queue in a buffer memory is included in a packet-switching connection and is transmitted to a packet-switching receiver via the line.

Abstract: A METHOD FOR ACCLIMATIZING AND        PROPAGATING PLANT TISSUE CULTURE SHOOTS               Abstract of the Invention A method for the acclimatization of plant propagules obtained by tissue culture techniques allows the direct field rooting of the propagules.  Tissue culture propagules are first treated under conditions which provide for hardening or lignification of the propagule prior to root induction.  The hardened propagules are exposed to a root induction medium for a time sufficient to initiate root formation, but are removed from the medium prior to root emergence.  The plantlets are then substantially immediately planted in the field where root formation occurs.  Root formation in the field avoids root shock which may occur when plantlets are transplanted after root formation is accomplished under greenhouse conditions.  The propagules which are planted in the field are protected by a light and moisture barrier which provides for controlled humidity, light intensity, and temperature conditions until the resulting plantlet is sufficiently acclimatized to survive in the uncontrolled environment.

Abstract: Light Modulating Material Comprising A Liquid Crystal Dispersion In A         Plastic Matrix Abstract A light modulating material consisting of droplets of liquid crystal in a clear or light transmitting, flexible plastic sheet or film, such as a cured epoxy. The light modulating material is prepared by dissolving liquid crystal in an uncured resin and then curing the resin so that droplets of liquid crystal spontaneously form and are uniformly dispersed throughout the sheet or film.  The new material shows a reversible, high constrast optical response from an opaque scattering mode to a clear light transmission mode when either the temperature of the material is changed to transform the liquid crystal into the isotropic phase or an electric field is applied across the material.  The material is optically responsive to strain, whereby under tension it acts to polarize incident light.  Curing the material in the presence of an applied field also causes it to act as an electrically addressable polarizer.

Abstract: ROTARY MULTICOLOR PRINTING MACHINE FOR SIMULTANEOUS                  RECTO-VERSO PRINTING            ABSTRACT       The printing machine has two interacting blanket cylinders (1,2) which are each inked by several offset plate cylinders (5,12) and between which the paper (P) to be printed on both sides runs through.  One of the blanket cylinders (2) is also in contact with a plate cylinder (8) carrying a collect printing plate which is inked in a multicolor manner by a further blanket cylinder (9).  This blanket cylinder (9) receives the inks from several appro-priately inked selective color inking cylinders (10). Also arranged between the two blanket cylinders (2,9), which are in contact with the plate cylinder (8) carrying the collect printing plate, is an adjustable and convert-ible plate cylinder (16) which, in a first working position, carries an offset plate and rests against the blanket cylinder (2) inked by the offset plate cylinders (12), whilst in a second working position it carries a selective color inking plate and rests against the blanket cylinder (9) inked by the selective color inking cylinders (10).          Thus, it is possible to produce on one side of the paper a multicolor pattern which is made by means of two differ-ent printing processes and in which either the number of colors used in collect printing or the number of colors used in offset printing is selectively increased by one color.
