Abstract: AUTOMATIC GAIN CONTROL OF A SINGLE GATE GaAs FEP AMPLIFIER   .         ABSTRACT OF THE DISCLOSURE           RF preamplification with AGC is employed because of the wide range of signal levels to which the RF input section of a radio is sub-jected.  A reduction in noise figure is obtained by using a single gate gallium arsenide field effect transistor (GaAs FEr) as the RF preampli fier and providing an AGC control signal to vary the gain of the RF preamplifier so that the subsequent circuits are not overloaded when high RF signal levels appear at the input.

Abstract: ABSTRACT OF THE DISCLOSURE      According to one aspect of the invention as disclosed, emulsion copolymer particles with diameters smaller than 1.5 micrometers and functionalized with cation exchange functional groups are prepared and suspended as emulsions in liquid media to form liquid cation exchange materials. Also, emulsion copolymer particles with diameters than 1.5 micrometers are functionalized with anion exchange functional groups by a method involving coagulation of the emulsion,  according to another aspect of the invention disclosed herein. Both weakly basic and strongly basic anion exchange resins are prepared from aromatic or acrylic copolymers, and the emulsion may be resuspended to form anion exchange emulsions.  Additionally, by a further aspect of the invention as disclosed, ions are exchanged between emulsion ion exchange resins and conventional ion exchange resins during both batch and column contact. This process may be used to place the emulsion resin or the conventional resin in the desired ionic form.

Abstract: ABSTRACT OF THE DISCLOSURE       Ore Sorting Apparatus An apparatus for ore sorting includes a neutron irradiator, and a detector assembly for detecting gamma radiation emitted by irradiated lumps of the ore.     The irradiated lumps after discharge from the irradiator, are divided into two channels by at least one bifurcating device held above a relatively high speed conveyor transporting the lumps.  Each channel is subsequently divided into three streams by diverting selected lumps from the channel as the lumps are projected from the end of the high speed conveyor.  The diverted lumps in each stream are allowed to fall on to a relatively low speed conveyor which then presents the lumps to the detector assembly.

Abstract: Method and apparatus for pre-treating lignocellulosic material in the continuous digestion of lignocellulosic material to cellulose pulp A B S T R A C T        In the continuous manufacture of cellulose pulp it has been found that air often remains in the lignocellulosic material subsequent to steaming the same. These air inclusions cause the lignocellulosic material to float in the cooking liquid, which results in interruptions in the digestion process. This problem is solved by means of the present invention, which relates to a method in which prior to being steamed, the lignocellulosic material is brought into contact with a heating medium. The method is characterized by supplying the heating medium to the advancing lignocellulosic material at several occasions; by distributing the heating medium in a manner such as to increase the temperature of the material in the direction in which it is advanced; and by separating condensed liquid from the lignocellu-losic material.       The invention also relates to apparatus for carrying out the above method.

Abstract: Abstract This invention relates to an extinguisher system for chimney fires that extinguishes the fire ansd set off concurrently an in-house alarm.  The alarm may be linked up to a fire extinguisher on the roof or to a heat sensitive device inside the chimeny.  The invention is particularly adapted to creosote chimney first where the main fuel is wood.            This invention relates to an extinguisher system for chimney fires.          Among the most hazardous of chimney fires are those resulting from a buildup of creosote that becomes ignited.  Uncontrolled, the fire can burn up the flue to the top of the chimney.            The cooperating parts of the invention are a roof mounted fire extinguisher in a protective housing, a supply line from the extinguisher up to the apex of the chimney, supported there, on a crosspiece.  A depending portion of the supply line inside the chimney terminates in a heat-activated spray nozzle.            When the system become operative, a battery operated in-house alarm is triggered concurrently.  The triggering means may be the drop in pressure in the supply line or it may be a heat sensor inside the chimney.            In further description of the invention reference is made to the accompanying drawing wherein, Figure 1 is a general layout of the system.            As shown in Figure 1, fire extinguisher 1 is accessibly located on the roof.

Abstract: ABSTRACT OF THE DISCLOSURE         An automatic switch wherein a pivotal switch lever is trippable by means of either a solenoid, a thermal element or a hand lever.  The grip member of said hand lever extends out through an opening in the forward side of the switch hous-ing which is configured to communicate the actual state of the switch contacts to an external observer, regardless of the position of the hand lever.  This is achieved through the use of a window mounted in the forward section of the switch hous-ing near the hand lever opening and in the region of the for-ward end of the pivotal switch lever, which bears a pivotal detent lever and an indicator strip.  This strip has one sec-tion which is disposed directly behind the window when the switch lever is in a certain position, but when the switch lever is in its other position that section is displaced from the window, effectively making it invisible to an outside observer.  Since the switch lever also contains the movable contact element of the switch (circuit-breakers),the position of said lever corresponds to the instantaneous position of the movable switch contact.
