Abstract: PROCESS FOR SLOW SOFTENING WATER                 Abstract of the Disclosure Water having calcium compounds therein is softened by admixing an alkaline compound therewith to change the calcium compounds inside a reaction zone into calcium carbonate.  A finely divided crystalline material is mixed with the water being softened prior to the addition of a flocculating agent containing trivalent metal ions.  The calcium carbonate produced in the reaction zone by sedimentation prior to addition of the flocculation agent is continuously withdrawn and recycled into the incoming water to be softened.

Abstract: AIR FLOW FOR EXPANDED METAL HEATER          Abstract of the Disclosure A dryer for articles such as a clothes dryer has a container for the articles and an air duct leading to the container for directing an air stream into the container for contact with the articles therein.  Located in the duct is a heater for heating the air stream before it enters the container and an air mixing baffle in the duct extending at an angle in the direction of the air stream flow and partially into the stream for creating an even temperature turbulence in the air stream and to break up any hot air stratification.  The duct is provided with an air inlet opening for supplying ambient air that mixes with the heated air as a result of the turbulence created by the mixing baffle thereby forming an even, reduced temperature of the air stream.  The ambient air opening is located generally along the flow path between the baffle and the outlet from the duct.  The baffle and ambient air inlet are located downstream of the heater and the baffle is downstream of the heater and upstream of the ambient air inlet and outlet from the duct.

Abstract: ABSTRACT OF THE DISCLOSURE         A feeding device is disclosed for guiding pieces of lum-ber to two longitudinal conveyors, each of which may be connected to a barking station.  By being able to feed to two conveyors rather than one, the problem of a  barking station becoming jam-med up when a log gets stuck is overcome and allows the operation to continue without closing down the conveying line.  The device has a photoelectric cell and a vertically swingable flap which swings over a gap in the lumber feed line.  Two feed conveyors are supplied, one in the gap and one on the other side of the gap so that the flap can direct logs either into the gap and one feed conveyor, or across the gap by means of the flap to the second conveyor.  The photoelectric cell controls the swingable flap de-pending on which feed conveyor is free to receive the next piece of lumber.

Abstract: ABSTRACT     Lengths of material are collected in side-by-side relation in a group and delivered as a group to a receiving station by an apparatus which includes a support table constituted by a number of spaced parallel arms pivoted coaxially with each other about one end.   Each arm has a finger which projects upward above the arm and which can be moved towards the pivot for moving the lengths laterally of themselves towards a stop adjacent the pivoted ends of the arms, and during this movement the arms are inclined downward towards their pivot at such an angle that the fingers need exert only a small force to move the lengths towards the stop.   A mechanism is provided for moving lengths of material individually or collectively on to the support table for movement by the fingers towards the stop, and a device spaced from the pivots emits a signal when the combined width of the lengths of material which have been moved towards the stop by the fingers reaches a predetermined value, and this signal initiates operation of a mechanism for moving the group of lengths having the predetermined width past the stop to the receiving station.

Abstract: Abstract of the Disclosure Phosphate rock and sulfuric acid are reacted under conditions which result in the formation of calcium sulfate dihydrate and phosphoric acid of about 35% to about 55% P2O5.  A two vessel reaction system is used in which the reaction slurry undergoes inter- and intra- vessel circulation. The solution portion of the slurry in the first vessel (the "dissolver") is preferably maintained at a negative sulfate concentration (i.e..excess Ca+2) and the solution in the second vessel (the "crystallizer") is pre-ferably maintained at a positive sulfate ion concentration.  Also preferred is that the second vessel be maintained at a reduced pressure, (e.g. to provide evaporative cooling).  Better filtration rates can thus be obtained due to the favorable shape, size and distribution of the dihydrate crystals. Most preferred is that a crystal modifier (e.g. a sulfonic acid, a sulfonic acid salt, tall oil fatty acids or esterified tall oil fatty acids) be present in the crystallizer.  Surprisingly, the sulfuric acid used in the process can be less (e.g., 0.5 - 10%) than the stoichiometric amount to convert the calcium in the feed phosphate rock to calcium sulphate.
