Title: Composition for washing fabric
Inventor: RUCK JULES B
IPC: C11D1/88
Filed: 1981-07-29
Granted: 1983-09-06
Abstract: "COMPOSITION FOR WASHING FABRIC"    ABSTRACT OF THE DISCLOSURE A composition is provided for washing fabric, particularly denim, prior to sale.  The composition includes an amphoteric surfactant, a builder which ensures that the surfactant in a washing solution, is initially in an anionic state, and a pH builder which causes the pH of the washing solution to decrease to thereby change the amphoteric surfactant to its cationic state.   In its anionic state the surfactant acts as a wetting agent to encourage such actions as pre-shrinking and dye-bleeding by the washing solution.  In its cationic state the surfactant can be adsorbed onto the fabric so as to exhibit fabric softening and anti-static effects.  A lubricant is preferably included in the composition to reduce uneven dye-bleeding caused by fabric to fabric abrasion in the wash cycle.

Abstract: PRINTHEAD AND BLADES THEREFOR ABSTRACT OF THE DISCLOSURE    A printhead for a dot matrix impact printer comprises a stack of thin printing blades each including a flat spiral coil mounted in a rim which is in turn connected by flexible mounting arms to a mounting portion.  Each blade has an arcuate printing arm extending from one side of the rim thereof and carrying a stylus, with the printing arms of adjacent blades being curved in opposite directions with the concave sides thereof facing each other so as to provide therebetween a large separation area to prevent wicking of ink from the styli to the coils of the blades.  Each print arm carries a stabilizing member extending from the concave side thereof, with the stabilizing members of adjacent blades overlapping for cooperation to divide the separation area between said blades into inner and outer regions, the outer region serving to block particulate debris and isolate it from the inner regions thereby to prevent interference with the anti-wicking function of the inner regions.  Assembly and operation of the printhead is facilitated by the use of separators between individual blades, the method of mounting the coils and the use of connecting tabs on the mounting portion of the blade adapted for insertion into the comple-mentary sockets of an associated circuit board.

Abstract: Abstract of the Disclosure A nozzle assembly for an electrostatic powder spray gun is disclosed.  The powder spray gun includes an electrically non-conductive barrel through which a high voltage electrical path passes.  The nozzle assembly is mounted in the open forward end of the barrel and includes a sleeve located on the center axis of the barrel for directing a flow of a pressurized gas, e.g., air, through the center of the nozzle assembly, a nozzle sur-rounding the sleeve defining an annular flow path for powder spray coating material encircling the flow of pressurized air and an air deflector cap for directing the pressurized air rad-ially outwardly and into the flow of powder spray coating material being emitted from the nozzle.  The air impacts the powder coat-ing material to form a conical spray pattern of coating material. The gun also includes an electrode extending out of the nozzle assembly for electrostatically charging the powder.  The nozzle assembly eliminates mechanical powder deflectors and the problems attendant therewith.

Abstract: ABSTRACT OF THE DISCLOSURE            This invention relates to an apparatus for automatically determining various stresses measured by a rectangular strain gauge rosette.  The invention receives signals from the rosette and provides signals representative of the maximum principal stress, the minimum principal stress and the maximum shear stress, the peak maximum principal stress, the minimum principal stress at the instant when the maximum principal stress is peaking, and the peak value of the shear stress.  A first analog signal processor provides stress signals representative of the maximum principal stress, minimum principal stress and maximum shear stress for each instantaneous input signal amplitude from each arm of the strain gauge rosette, and a second signal processor receives the stress signals and provides output signals representative of the peak maximum principal stress, minimum principal stress at the instant of peak maximum principal stress, and peak maximum shear stress.  Using the invention a designer of a vehicle or other apparatus normally subject to stress can observe the aforenoted stresses immediately during a test and either repeat the test or very slightly alter it to affirm the data or to detect subtle differences, knowledge of which would otherwise be lost using prior art techniques.

Abstract: ABSTRACT OF THE DISCLOSURE           An optimized two piece fastener system and a related method for providing an optimized fastening system including a pin member and a collar having an optimized strength to weight ratio with the materials of the pin member and collar having a predetermined tensile strength ratio.  The smooth shank portion of the pin is of a diameter sufficient  to  provide  the  necessary  shear strength to accept the design  shear  load.   The  swaged  collar  has  collar  grooves  and shoulders interlocking the pin grooves and shoulders, the pin member and  the  collar being of different materials having ultimate shear stresses of different magnitudes with the ratio of the shear stresses of the pin member to the collar being such that crushing of the pin member in swage is substantially avoided.  The axial widths of the pin grooves and shoulders and the collar grooves and shoulders are preselected in accordance with the relative shear strengths of the different  materials  so that  the  pin  shoulders  and  the  collar shoulders  are  adapted  to  fail  in shear  generally  at  the  design tensile  load  applied between the pin member and  the  collar.   The collar has a minimum wall thickness and hence weight, such that after swage  compressive  yielding  could  occur  generally  at  the  design tensile load.  The collar is swaged into the pin grooves via a swage anvil having an effective  throat swage portion.   The collar has a predetermined volume of material which is generally at least around 20% greater than the available volume defined by the effective throat swage portion and the confronting portion of the pin grooves into which the collar is swaged.  In one embodiment the pin member prior to swage has a pintail portion connected with the grooved portion by a breakneck groove, the pintail portion being adapted to be gripped by a tool actuable for applying a relative axial force between the pin member and the collar.  The breakneck groove is adapted to accept a combined tensile and bending load and to fracture at a preselected axial force after completion of swaging.  The breakneck groove has a stress concentration factor provided for fracture at the preselected axial force and further providing for fracture within around 12% from the  preselected  axial  force  when  the  fastener  is  applied  to workpieces  having its  collar engaging  surface  at  an angle  of 7° normal to the axis of the pin member.

Abstract: Abstract An improved test system for performing DC and AC parametric and dynamic functional testing of multi-terminal integrated circuits is described.  All of the circuitry for producing and responding to D.C. and high-integrity stimulus and response test signals is located within a Test Head module sized for use in close proximity of the device under test.  A high-integrity bus in the Test Head interconnects the high-integrity producing and handling circuits, with inexpensive connectors and batch fabricated printed circuit board techniques.  A Controller provides digital test commands for energizing the test signal producing circuits within the Test Head and for evaluating the test results.  The control and measurement signals passing between the Controller and the Test Module require no special conductor implementation techniques. A unique detachable, modularized bussing scheme between the Controller and Test Head and within the Test Head enables the test system to be manufactured at minimum cost, while maximizing reliability, signal integrity and manufacturing repeatability from system to system and enables rapid replacement and interchangability of test circuits and functional capabilities without sacri-ficing the quality of bus structure that carries the high integrity signals.
