Abstract: In order to modify the immune system in humans having symptoms of a disorder of the immune system characterized by the presence of lymphocytes not apparently activated such lymphocytes are deactivated by a limited and closely controlled extracorporeal irradiation of an intensity and duration sufficient to cause the symptoms to disappear.
Abstract: A tennis ball throwing machine pneumatically expels tennis balls through a barrel having on one side of its inner wall a Velcro strip for spinning the ball. The barrel is rotated about its lengthwise axis so that the sense of the spin, topspin, backspin, or right or left hand spin, varies in dependence upon the angular disposition of the Velcro strip as of the moment the ball passes it. The output end of the barrel is bent at an angle to its lengthwise axis resulting in an orbital motion.
Abstract: Novel heat resistant heterogeneous thermosetting compositions of matter are described wherein one functionally useful thermosetting reinforced plastic friction material comprises a homogeneous continuous phase and another dissimilar functionally useful thermosetting reinforced plastic friction material comprises a second homogeneous phase dispersed heterogeneously as granules in random manner throughout the first phase, whereby a functional advantage is obtained over a simple homogeneous mixture of the two materials, throughout the life of the friction element.
Abstract: A pre-assembled insert for a container used for aging wine has multiple planar members angularly disposed about a central shaft wherein the parameters of the oxidation and extraction reactions occurring during aging of the wine are known as a function of the surface:volume relationship of the container and its insert.
Abstract: Green coal is charred in pre- and post- treatment carbonizers, then crushed, mixed with pitch, briquetted, tempered in a tempering oven, recirculated with succeeding green coal to char in a reducing atmosphere through only the latter part of the pre-treatment carbonizer and through the post-treatment carbonizer, cooled, and separated from the as yet unbriquetted char. The pre-treatment carbonization is characterized by having air updrafted through all the airbox zones under the travelling grate.
Abstract: A hay bale feeder comprises a cradle having opposed end plates and side formed by angularly disposed conveyors movable laterally relative to the longitudinal axis of the cradle. Each conveyor comprises a pair of substantially parallel endless chains carried by sprockets on respective upper and lower shafts extending between the end plates, and a plurality of slats or bars are fixed to the chains for movement therewith. The slats or bars have spikes extending therefrom to engage in and remove hay from a bale carried in the cradle. The conveyors are driven in synchronism so that upper runs of the conveyors move in the same general lateral direction. Guide plates support the conveyor chains between the respective upper and lower shafts.
Abstract: The present invention relates to a new method of making tubular vials and ampules from glass tubing. The method according to this invention is essentially characterized in that the glass tubing used is closed at both ends and has a dot-shaped opening close to one of the sealed ends. The opening can be sealed by a film to prevent impurities from entering the glass tubing. Throughout the operational process in the production of vials and ampules, a slight excess pressure exists in the glass tubing by applying heat, which further prevents impurities from entering the glass tubing.

Abstract: Tennis balls are sequentially fed to an entranceway in the top of the plenum chamber of a pneumatic throwing machine by a flexible disk which rotates about a vertical axis. The balls roll by gravity down a chute onto the feed disk which has angularly spaced pocket holes. To prevent jamming of unpocketed balls between the top of the feed disk and the feed chute, the disk is sufficiently flexible as to be deflectable by an unpocketed ball and be discharged through an open escape path.
Abstract: An extruded plastic tray has along the upper side of its rear portion a forwardly opening "C"-shape channel into which "C"-shape clips slideably engage by bowing the bights of the clips so that the arms of the "C"-shape clips can pass between the arms of the "C"-shape channel on the tray. In the bights of the clips are "I"-shape slots through which the ends of divider strips may be forced so as to bend back the side edges of the stem of the "I".
Abstract: A wooden door sill has an inclined tread portion rising to a threshold which lies beneath the door when the latter is closed. The threshold has a longitudinal upwardly-open groove containing a strip. In order to provide an adjustable fit of the strip against the under edge of the door, the strip is screwed down against a resilient compressible filler strip in the bottom of the groove.
Abstract: A system for gathering and transporting debris from a surface including first and second rakes having an adjustable head relative to the handle of the rake and a strap on a topmost portion of each rake handle adapted to attach to forearms of the user and handgrips disposed below the straps on each of the rakes for grasping by the hands of the user, each rake adapted to be operatively associated with one of two hands of the user and used in concert so that the rakes can be used to put debris between the two rake heads and be lifted up.
Abstract: Carbonaceous raw material, such as lignite coal, having first been passed successively through a moving grate stoker furnace, a shaft furnace and a quench chamber is screened so as to remove from the end product substantially all +12 mesh and larger particles which are then crushed to -12 mesh screen size and recirculated into the stream of raw material enroute through the moving grate stoker.
Abstract: Green petroleum coke is partly devolatilized by transporting horizontally in static bed form through a furnace over a series of air box zones including a minority of zones adjacent the input end of the furnace and a majority remote from the input end and further devolatilized by soaking in a shaft furnace until at least most of the residual volatiles are driven off. From the shaft furnace the devolatilized coke is water quenched and steam produced in the quencher is mixed with downdrafted gases from said furnace to cool the same and prevent premature combustion.
Abstract: A proteolytic enzyme-containing composition is prepared having stabilized proteolytic enzyme activity and the ability to convert scleroproteins to water soluble products without racemization. The composition contains a proteolytic enzyme system from Bacillus cereus and an anionic detergent. The proteolytic enzyme system consists of a proteolytic enzyme oligomer that is retained by an ultrafilter membrane that retains molecules larger than 10,000 molecular weight and is reversibly interconvertible with a proteolytic active subcomponent that passes through the same membrane that retains the oligomer. The anionic detergent is preferably an alkyl sulfate or sulfonate or an alkyl-aryl sulfate or sulfonate.
Abstract: A disposable normally closed all plastic reciprocating valve is adapted to be used in a supply line for fluids supplied to or extracted from a patient. The valve is opened by inserting a tube into one end thereof.
