Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus for and method of comparing an inventory of a competitor's products with a supplier's suggested in-ventory are provided.  The apparatus utilizes a competitor's part numbers sheet having a first arrangement of the com-petitor's part number for marking the quantity of each number to define the inventory of competitor's products.  A supplier's part number sheet is provided having a second arrangement of the supplier's part numbers thereon which is identical to the first arrangement with the supplier's sheet having an opening therein adjacent its numbers.  The supplier's sheet is aligned over the competitor's sheet so that the supplier's sheet hides the first arrangement of part numbers and each quantity of competitor's part numbers is viewable through the opening opposite a corresponding supplier's part number.  Thus, each supplier's part number and its viewable quantity comprise the supplier's suggested inventory.

Abstract: ABSTRACT OF THE DISCLOSURE A transducer assembly includes a first half wavelength double-dummy section having a pair of quarter wavelength ultrasonic horns and a driving element sandwiched therebetween.  A second half wavelength stepped amplifying section extends from one end of the first section and has B theoretical res-onant frequency equal to the actual resonant frequency of the first section. When used as a liquid atomizer, the small diameter portion of the stepped amplifying section has a flanged tip to provide an atomizing surface of increased area.  To maintain efficiency, the length of the small diameter portion of the second section with a flange should be less than its length without a flange.

Abstract: Abstract An electromagnetically operated friction clutch is disclosed of the type including an axially movable armature member which is drawn into frictional driving engagement with a friction surface on an inner body to establish drive through the clutch, in which a torque overload deenergization of the electromagnetic coil is provided.  The clutch is provided with a torque boosting arrangement in which drive from the axially movable armature is transmitted through the series of balls disposed in corresponding pockets formed in a radial face of the armature and an opposing radial face of a clutch element drivingly connected to one of the primary clutch members.  The action of the balls in the pockets creates a torque boosting effect increasing the engagement pressure exerted on the frictional engagement surfaces. The torque overload release arrangement includes a mounting of the clutch element In axially and rotationally restrained by means of a spring element. The axial movement of the clutch element against the spring bias In response to the transmission of a particular level of torque is employed to sense a torque overload condition, and by positioning a microswitch activated by a predetermined extent of axial movement of the clutch element, the electromagnetic coil is deenergized at a predetermined torque level.  The clutch may be reenergized at high speed by a manual switch reenergizing the coil relay, drawing the friction surfaces into engagement.

Title: Wire-reinforced hose and method of  making same

Granted: 1982-07-13
Abstract: ABSTRACT OF THE DISCLOSURE         A wire reinforced hose and method of making same are provided herein.  The hose is defined of a helically wound strip which has at least one integral preformed convolution therein and a wire disposed in the con-volution with the helical winding being such that the convolution with the wire disposed therewithin extends in a helical path along the length of the hose and the hose has a tubular inside surface with the helical wire concealed therewithin when viewing such tubular inside surface. The preformed convolution has a roughly U-shaped cross-sectional configuration defined by a bight and a pair of legs extending in parallel relation from opposite ends of the bight, the legs having inside surfaces which define corresponding surfaces of the groove and the inside surfaces engage the wire and hold same in a precise helical path.  The wire-reinforce hose so provided has improved quality since the wire is wound with optimum precision.  There is little likelihood of separation and relative movement between the strip and the wire to result in premature weakening and failure of the hose.          Moreover, the inside surface of the hose is relatively smooth.

Abstract: ABSTRACT OF THE DISCLOSURE      A pair of continuous slide fastener stringers are longitudinally fed by longitudinally reciprocable grip means and driving roller means that is selectively actuatable.  As the slide fastener stringers are advanced, one of the stringers is threaded through a slider being fixed in its path of travel.          The slide fastener stringers are cut off transversely across element-free gaps, and then the severed stringer pieces are moved forwardly until their leading end portions are positioned in a molding device, which molds a separable end stop on the leading end portions.  The driving roller means is continuosly driven to advance the slide fastener stringers until element-free gaps arrive at the cutter means, whereupon the driving roller means is de-energized.

Abstract: ABSTRACT OF THE DISCLOSURE             A quill drive comprising a housing adapted for mounting on machine tools.   A quill is sliadably mounted in a longitudinal bore in the housing, and is longitudinally positioned by a ball screw.  The ball screw is driven for longitudinal positioning of the quill by a variable speed, reversible motor.  The quill rotatably supports a spindle for driving various cutting tools.   The spindle is advanced longitudinally by the quill and is rotatably driven by a second motor.   The quill drive can be used singally or in a multiple arrangement on transfer machines or other auto-matic equipment.  The unique design has fewer parts resulting in a simple reliable, relatively inexpensive device which is compact and easy to use.  A relatively simple modification of the gear box converts the quill drive into a drive for tapping threaded holes.

Abstract: ABSTRACT OF THE DISCLOSURE:        An improvement in a method for manufacturing dipeptides from an N-substituted aspartic acid and a phenylalanine lower alkyl ester.  The two starting materials are allowed to react with each other in the presence of an immobilized metallo-proteinase in an organic solvent immiscible with water.  The enzyme can be recovered for reuse thereof.  The loss of materials due to the hydrolysis of the phenylalanine lower alkyl ester is reduced, so that use of the phenylalanine lower alkyl ester in a nearly stoichiometric quantity suffices for the reaction to ensure an improved yield and reduction in cost of industrial production.

Abstract: Abstract:       A secondary surveillance radar is arranged to monitor the relative amplitudes of sum signals and difference signals received from a target in response to interrogations. Only those replies for which the sum signal exceeds the difference signal by a predetermined amplitude are accepted as valid to avoid degradation of the performance of the radar due to "punch through".  "Punch through" stems from distortions in the radiation pattern of the radar and is often caused by reflections of the radar signals by large objects.  A directional receiving antenna generates sum (?) and difference (.DELTA.) signals and replies are accepted as valie and gated to an output only if a quantity log .DELTA./? exceeds a reference when compared at a comparator.

Abstract: ABSTRACT OF THE DISCLOSURE           In a method for the production of thermally insulated composite sections a free space is formed between at least two metal sections, held spaced apart, and sealed at the bottom.  The space is filled from its open side with an insulating material which at first is in liquid form and then hardens.  In order to produce such sections, particularly also those of large size, with the least possible expense for labor and material, and at the same time to achieve the most favorable heat insulation values in the insulating region, solid insulating material layers positively and frictionally joining together the metal sections, and insulating layers hardening with a porous structure are introduced in succession into the free space.  Each layer fills only partly the free space.  The introduction of the solid insulating material layers and of the insulating layers is effected with the aid of a plurality of inlet nozzles whose actions are chrono-logically staggered and which are disposed one behind the other in the working direction of the filling operation.  The same material is used for the porous insulating layers as for the solid insulating material layers.
