Abstract: ABSTRACT OF THE DISCLOSURE :          The system enciphers a digital signal of n-bit words Ni into an enciphered signal of n-bit words Ri. In the enciphering unit, a logic circuit delivers each enciphered word Ri through a logic operation g performed on the word Ni and on an n-bit memorized word Pi-1. An addressing circuit formulates an address word Ai-1 having a bit fully or partly belonging at least to the preceding enciphered word Ri-1. A memory of 2a predetermined Pi-1 words is read by each address word Ai-1 in order to transmit a corresponding word Pi 1 to the logic circuit for it to perform the g operation such that Ri = g(Ni, Pi-1) The deciphering unit receives the enciphered words Ri for formulating the address words Ai controlling the reading of the corresponding words Pi out of 2a memorized. Each deci-phered word Ni is obtained by a logic operation h, referred to as contrary to g, performed on the enciphered word Ri and on the memorized word Pi-1, such that Ni = h(Ri, Pi-1) The memories can be programmed by computers which, as per a predetermined algorithm,compute a table of words Pi for a given key.

Abstract: TITLE OF THE INVENTION:  Glass Fiber Reinforced Laminate and Method of Making the Same ABSTRACT OF THE DISCLOSURE         Glass fiber reinforced plastic laminates including randomly oriented glass fibers, embedded within unsaturated polyester resins, are provided over at least one surface thereof with a gel coat, essentially free of the glass fibers.          The gel coat is formed from resins which are polymerizable in the presence of ultraviolet radiation.  The gel coat is at least partially cured on a transparent carrier film by exposing gel coat resins to ultraviolet radiation.  Thereafter randomly oriented glass fibers and unsaturated polyester resin syrup are applied onto the gel coat to form the resulting laminate.  The gel coat is selected to provide superior weathering characteristics and resistance to deter-ioration from ultraviolet radiation exposure, e.g., sunlight, when compared to the corresponding properties of the un-saturated polyester resin in which the randomly oriented glass fibers are embedded.

Abstract: ABSTRACT OF THE DISCLOSURE         A water vapor generator of the type having electrodes in a vaporization vessel is disclosed.  Current passed through the water between electrodes causes water in the vessel to heat and boil off as steam, make-up water being added when the current drops below a preset minimum value.          The make-up water is cut off when a preset maximum value is reached.  Thus, the generator operates through successive cycles each containing a descending "boil" leg and an ascending "fill" leg.  As water is boiled the mineral content in the vessel becomes more and more concentrated causing increasing conductivity of the water.  In order to return the contained water conductivity to its design value the frequency of the boil/fill cycles is measured over several cycles and compared with a predetermined value.  If the measured frequency is higher, this indicates a higher than desired water conductivity and a drain cycle is initiated by operating a drain valve.  The amount of water drained out of the vessel is proportional to the deviation of frequency from the predetermined value.  The frequency can be measured by the duration of a predetermined number of cycles and this is then compared with a predetermined duration corresponding to the predetermined frequency.  The apparatus used may include a count down sequencer which starts to step through several relays which have successively higher minimum thresholds and a cycle counter which starts counting cycles at the same time.  If, when the cycle counter has finished counting the predetermined number of cycles, the count down sequencer has not finished counting, one of the relays will be energised and this will cause the outlet valve to open and remain open untilthe electrode current drops to the threshold valve for that relay.

Abstract: BLADE PITCH ACTUATION SYSTEM                      Abstract Blade pitch actuation system wherein the blades are hydraulically maintained in phase with one another.  The system comprises hydraulic actuators each adapted to drive a single blade in a pitch change mode of operation. Fluid flow to the actuators is controlled by a blade ac-tuator control valve in fluid communication with the ac-tuators and an hydraulic fluid source and drain.  An in-put member of the control valve is provided with passages which provide selected communication between the hy-draulic fluid source and drain and passages in cooperat-ing control valve feedback members each operated by, and in fluid communication with one of the blade actuators. The input and feedback members are positionable along one another such that selective positioning of the input member causes simultaneous selected pressurization and draining of the blade actuators through the feedback members thereby effecting a desired, phased blade pitch setting.  The phased movement of the blades to such setting causes a corresponding movement of the feedback members nulling the actuator control valve and prevent-ing deviation in blade pitch from the desired setting.

Controls on the quantity and quality of light are provided.  In one form of control, a translucent cylindrical rod extends into the light source cavity and has an end face exposed to the light source.  The translucent rod has an opaque lateral surface interrupted on one side by an axially extending light transmitting window. In another form of control, a window in the side of the translucent rod receives light from the light source.  In a third form of control, a cylindrical shell with opposed parallel windows takes the place of the translucent rod.  In all cases, the translucent rod or shell has a head portion accessible exteriorly of the body for turning it to change the amount of light passing through the elong-ated opening.

Abstract: ABSTRACT OF THE DISCLOSURE             Films which are rapidly soluble in cold and warm water are formed from blends of water soluble polyvinyl alcohol (partially hydrolyzed polyvinyl acetate) and polyacrylic acid.  The polymers are compatible and form homogeneous mixtures from which clear, transparent, non-tacky, easily handleable, mechanically strong films can be formed.  The films are stable at both low and high humidity conditions, i.e., the films do not become brittle or tacky and retain their high rates of dissolution in water even after being stored in low or high humidity environments at both high and low temperatures.  Further, improvements are achieved by incorporating a plasticizer into the polymer blend.  The films are also heat sealable and biodegradable and are most useful in packaging applications, such as for dry detergents and similar water soluble commodities.

Abstract: METHOD AND APPARATUS FOR CONDENSATION HEATING          Abstract of the Disclosure A method and apparatus for condensation heating.     Articles to be heated are conveyed into a heating chamber which is filled with vapors of a fluid having a relatively high boiling point.  When the vapors contact the article to be heated they condense thereon and transfer the latent heat of vaporization, thus heating the object.  Vapors escaping from the heating chamber are trapped by flows of carrier gas at the inlet and outlet of the heating chamber.  The carrier gas, which is thus partially saturated with vapor, is channeled into a gas/vapor separator wherein the vapor is extracted and recycled back to the heating chamber.
