Abstract: ABSTRACT OF THE DISCLOSURE      An improved drive unit for a food processor of the type wherein the drive unit is enclosed in a base housing and has a vertically extending spindle which extends into a processing bowl and carries rotary tools thereon.  The drive unit comprises a horizontally mounted universal motor carrying a pinion gear at the end of its shaft.  A ring gear meshes with the pinion and encircles the motor on a concavo-convex support structure.  The support structure is coupled to the vertical spindle.  Included in the drive unit are a novel three point shock mounting for the motor and an automatic brake to prevent coasting of the tool after the motor is deenergized.  In a further embodiment of the driva unit the motor and the concavo-convex ring gear are held in a motor mount which is vibrationally isolated from the base housing for providing quieter operation.  This mount arches up over the dome of the ring gear which in turn arches up over the motor.  A lockable adjustment is provided in the motor mount for adjusting the engagement between the pinion gear and ring gear, and another form of automatic brake is shown.

Abstract: PREPARATION OF SODIUM ORTHOPHOSPHATE MIXTURES     ABSTRACT     A mixture of disodium and monosodium ortho-phosphate in a 2:1 mole ratio is prepared by sequent-ially reacting phosphoric acid with monohydrate process soda ash and caustic soda in a semi-solid reaction medium.      Milled monohydrate process soda ash is contacted in less than stoichiometric proportions with phosphoric acid and the resultant orthophosphate con-taining reaction mixture is brought to a sodium to phosphorus mole ratio of about 1.67:1 by subsequent reaction with caustic soda.  The final reaction product of mixed disodium and monosodium orthophosphate is suitable feedstock for conversion to sodium  tripoly-phosphate.

Abstract: ABSTRACT OF THE DISCLOSURE         An in-ground swimming pool which utilizes a relative-ly flexible, continuous sheet-like wall member in combination with a bottom construction which is formed from polyurethane foam.  The polyurethane foam bottom is reinforced at the surfaces of concave curvature with rail-like concrete members to which the foam is bonded.          Also disclosed is  a method of forming the polyure-thane bottom which consists of applying a relatively thin coat-ing of polyurethane foam to the bottom excavation and immediate-ly placing a sheet of polyethylene, 2 to 4 mils thick, over the foam before the foam has set, confirming and adhering the polyethylene sheet to the foam and earth surface.  The final steps include applying a series of polyurethane foam layers by spraying over the polyethylene sheet to achieve a desired thickness.  By following the procedures disclosed, the foam surface can be controlled to obtain the desired pool bottom smoothness.

Abstract: ABSTRACT OF THE DISCLOSURE     A monolithically integrated filter circuit having low transmission losses and a high upper cutoff frequency has at least one charge transfer device with a self-contained transmission channel provided on a doped semicon-ductor body to which transmission channels of other charge transfer devices are connected at predetermined nodal points.  Each charge transfer device has shift electrodes arranged over an insulating layer over a limiting surface of the semiconductor body which are charged with clock voltages.  Shift electrodes in the immediate proximity of a nodal point are charged with the same clock voltage but are separately allocated to different transmission channels and have a pre-determined surface area ratio with regard to each other and the sum of their surface areas is equal to the surface area of an adjacent shift electrode which is allocated to the self-contained transmission channel.  The transmission channel formed by the electrodes at a nodal point is disposed at an angle with respect to the transmission direction of the self-contained transmission channel which is approximately 45°.

Abstract: Abstract of the Disclosure A method of diagnosing cystic fibrosis,  identi-fying carriers for cystic fibrosis, and non-carriers or "normal" persons.  Heretofore, no carrier or prenatal de-dection method procedure for cystic fibrosis existed.  The detection is based on the discovery of the genetic abnor-mality or biochemical defect in cystic fibrosis,  which occurs in mitochondria, minute bodies found in the cyto-plasm of most cells which are the principal energy source of the cell and contain the cytochrome enzymes of terminal electron transport.  The method comprises an assay carried out on preparations derived from human cells possessing mitochondria.  The assay may be a kinetic assay of the enzyme complex of the energy conserving site of the mito-chondrial electron transport system of the cells or an assay of mitochondrial  activity governed by the enzyme complex.  The assay is then evaluated by comparison with standards established as the result of similar assays of cells of other subjects of known condition.  The assays provide determination of characteristics which differ in the  three  types  of  individuals  (normal,  carrier,  and affected) and provide a basis for their distinction.

Abstract: ABSTRACT OF THE DISCLOSURE         Olefinically unsaturated compounds containing 4 to 36 carbon atoms and having boiling points above 40°C are converted into the corresponding vicinal diols by reaction with formic acid and hydrogen peroxide at elevated temperature while intimately mixing and by subsequent saponification of the diol formates initially formed.  The formic acid is used in amounts of 2 to 6 moles per mole of double bond and hydrogen peroxide is used in a concentration of 35 to 98 percent by weight.  The reaction is carried out a temperature between 40 to 80°C.  The desired diols can usually be obtained in reaction times of less than seven hours and in yields of approximately 90%.

Abstract: RESISTANCE WELDING SEQUENCE CYCLE CONTROL          ABSTRACT OF THE DISCLOSURE         A method and apparatus are shown for controlling the cycle of a resistance welding device by providing compensation for variations in the effective weld area and the primary input electric power variations through a composite correction applied to the length of the squeeze time cycle portion prior to the weld cycle portion when weld current is activated.  Compensation is made for secondary weld current variations by altering the length of the hold cycle, during which electrode contact is maintained with the work subsequent to the weld cycle portion, to change the amount of heat quenched from the weld zone.  Further by sensing the condition wherein either the electrical input or the motive power that drives the movable electrode is beyond correctable limits, the welding cycle is aborted when suitable quality welds cannot be made.

Abstract: ABSTRACT         The manufacture of information carrying discs has required relatively slow processing because of the need to conform materials to exact mold shapes and to remove entrapped gases.  The use of either preformed films or liquids provides different degrees of this problem. The use of a process whereby a bead of photopolymerizable liquid is moved across the mold surface has been found to accurately fill the mold, remove air bubbles, and enable rapid replication of information carrying discs.

Abstract: ABSTRACT     A childproof safety screw cap and container having yieldable cap retainer means which are overcome, to effect cap removal, by a quarter-turn twist that produces a rela-tively large axial cap travel due to the provision of mul-tiple screw thread elements thereon.  The cap can be pushed straight on, accompanied by bypassing of the threads.  The retainer means and the threads increase their interlock action if the cap is squeezed laterally, as by the act of a child applying its teeth to the cap.  A shielding flange on the container defeats efforts to bite the cap under its bottom rim, and a bevelled top peripheral portion of the cap defeats its being gripped at the top, by the teeth.    The advantage of the present construction over the devices of the prior art is that an especially simple one-quarter turn movement, while squeezing, is all that is required to remove the cap regardless of the initial position thereof, as opposed to the prior arrangements where movements of as much as one-half turn or more were required.
