Abstract: ABSTRACT OF THE DISCLOSURE           A continuous cyclic process for the production of chlorine dioxide includes the formation of a gaseous mixture of chlorine dioxide, chlorine and steam from an aqueous reaction medium containing sodium chlorate and hydrochloric acid at an activity below about 1N.  Chlorine dioxide is recovered from the gaseous mixture.  Sodium chloride formed in the reaction is deposited in the reac-tion vessel and is removed therefrom.  The continuous cyclic process forms part of an effluent dioxide is used as a bleaching chemical and from which sodium chloride is removed.  Sodium hydroxide solution used in caustic extrac-tion of the pulp in the bleach plant is formed by electro-lysis of an aqueous solution sodium chloride, which may be formed from that removed from the chlorine dioxide genera-tor and/or recovered from the pulp mill.  Sodium chlorate feed for the chlorine dioxide generator is formed by electrolysis of aqueous sodium chloride solution, which may be formed from that removed from the chlorine dioxide generator and/or recovered from the pulp mill and not used to form sodium hydroxide solution.  Inefficiencies in the production of chlorine dioxide and losses from the system are made up by the use of additional chlorine and sodium chloride.

Abstract: ABSTRACT OF THE DISCLOSURE           A continuous flow expander and method for ex-panding particulate material, more specifically for grain or cattle fodder, is provided whereby material to be expanded is transported in a substantially continuous manner through a pressurized region wherein it is heated, steamed and pres-surized by a counterflow of dry steam created from available city water by a recirculating steam boiler.  The material is then ejected by another flow of dry steam created from availably water into a lower pressure region for expansion.          Enthalpy in the ejection region is automatically maintained within a predetermined range, for grain or cattle fodder from 450 to 750 BTU per pound of moisture being ejected, re-gardless of the moisture content of the material, by varying steam boiler output and, if necessary, material flow rate.          An expanded product requiring no further drying prior to use or storage is thereby provided with minimum energy use.

Abstract: ABSTRACT OF THE DISCLOSURE    A socket base contact is self-biased to a position remote from its terminal and an insulating plate is driven by a spring between the contact and the terminal when a load device is re-moved from the socket.  When a load device is inserted into the socket, the insulating plate may be manually moved to permit en-gagement between the base contact and its terminal.  The force exerted against the base contact by a load device in the socket is sufficient to prevent the insulating plate from being driven between the base contact and its terminal.

Abstract: ABSTRACT OF THE DISCLOSURE Demodulation of a wideband spread spectrum four-phase PSK (phase shift keyed) modulated carrier signal is accomplished by means of a correlator which phase shifts the modulated carrier signal as a function of a locally generated PN (pseudo-noise) sequence to provide a narrow band two-phase PSK modulated carrier signal.  The two-phase modulated signal is fed to a matched filter wherein undesired signal components are removed so as to provide an IF (intermediate frequency) signal.  A carrier re-covery phaselock loop demodulates the two phase modulated IF signal to provide a baseband signal.  A timing recovery loop operates upon the baseband signal to provide timing signals for the locally generated PN sequence to synchronize the local PN sequence with the modulated carrier sequence.  A bit timing loop and a sample and hold means operate upon the baseband signal to detect the modulating data to provide an output signal which is a function of the modulating data.

Abstract: ABSTRACT OF THE DISCLOSURE          Clutches as presently known suffer from the disadvantage that even after the clutch is disengaged the friction facings of the clutch plate tend to maintain contact with the engaging surface of the fly wheel.   This results in failure in changing over the speeds by the transmission.  The present invention relates to a dry-disc type clutch, and more particularly to a clutch of the type which includes a fly wheel having an annular engaging surface and secured on a drive shaft, a clutch plate axially slidably supported on a driven shaft which is positioned in coaxial relationship to the drive shaft, annular friction facings secured to opposite surfaces of the clutch plate and an annular pressure plate adapted to urge the friction facings of the clutch plate against the engaging surface of the fly wheel.  A plurality of recesses or shallow grooves are defined in the surface of one of the annular friction facings which faces the engaging surface of the fly wheel.   Accelerated air streams are introduced from the exterior through the fly wheel into the plurality of grooves so as to aid in the separation of the friction facing of the clutch plate from the engaging surface of the fly wheel as a result of a hydrodynamic force created by the air streams.

Abstract: PULSATING JET SPRAY HEAD        ABSTRACT          A spray head including a handle disk having an exposed front wall and manually engageable peripheral portion the wall having a set of jet nozzles arranged in a circle, the perforations having common communication with a set of fine spray nozzles; the handle disk being mounted for limited arcuate movement with respect to a housing having a mating perforated wall for exposing the jet nozzles or the perforations communicating with the spray nozzles.  The interior of the housing forms a chamber in which water is caused to rotate and drive a rotor having as least one opening which passes intermittently across the jet nozzles or perforations depending on the position of the handle disk.  When the jet spray nozzles are activated the effect of the rotor and its slot is to cause the jet nozzles to produce pulsating jets.  When the fine spray nozzles are activated, the water entering the perforations is diffused to produce essentially constant flow through the fine spray nozzles.
