  • Linespacing apparatus
    Patent number: 4365904
    Abstract: A linespacing apparatus includes a slip clutch assembly which is driven by an electric motor. The slip clutch assembly includes a face cam which drives a linkage which, in turn, indexes a platen in order to linespace the platen. The face cam includes an abutment portion which abruptly halts the motion of the linkage and the slip clutch assembly prevents bounce or recoil of the linkage thereby promoting smooth operation of the apparatus. The linkage may be adjusted by an operator to vary the amount of rotation of the platen during each operating stroke of the linkage.

  • Cartridge ribbon lift apparatus
    Patent number: 4364679
    Abstract: A cartridge ribbon lift apparatus is provided in which a pivotally mounted cartridge, containing a ribbon, is pivoted upward to a printing position by a linkage which is operated by a solenoid. When the cartridge reaches the printing position a second linkage latches the cartridge in the printing position for repeat and burst speed printing and the cartridge remains in the printing position as long as the solenoid remains energized. While the cartridge is latched in the printing position the first linkage is restored to its initial operating position.

  • Overtemperature protector for an electrically heated appliance
    Patent number: 4360725
    Abstract: An overtemperature protector for an appliance having an electrical heating element includes a fixed contact, a movable contact carried by a spring blade and settable into engagement with the fixed contact to complete the energizing circuit to the heating element by stressing the spring blade, and a torsion spring having an arm engageable with the spring blade to hold the contacts in engagement against the stress bias of the spring blade. A fusible pin retains the arm of the torsion spring in engagement with the spring blade, thus locking the contacts closed. Excessive heat in the appliance causes the pin to soften, thereby allowing the torsion spring to shear the pin and release the movable contact to open the heating element energizing circuit.

  • Synthesis 2-alkyl cyclopentenolones
    Patent number: 4359586
    Abstract: 2-Hydroxy-3-methylcyclopent-2-en-1-one was synthesized in a five-step synthesis starting from 2-methyl-1,3-butadiene. Novel intermediate steps include the hot tube isomerization of 1,1-dihalo-2-methyl-2-vinylcyclopropane to give 1-methyl-4,4-dihalocyclopent-1-ene, hydrolysis to 3-methyl-2-cyclopenten-1-one, epoxidation of the latter using a phase transfer catalyst, followed by catalyzed isomerization to produce 2-hydroxy-3-methylcyclopent-2-en-1-one in high overall yield.

  • Corrosion-resistant powder-metallurgy stainless steel powders and compacts therefrom
    Patent number: 4350529
    Abstract: A process is disclosed for improving the corrosion resistance of stainless steel powders produced by atomization in an oxidizing atmosphere whereby silicon present in the powder tends to form silicon oxides on the powder surface. The process comprises adding an effective proportion of a modifier metal selected from the group consisting of antimony, arsenic, and bismuth to the melt prior to atomization. The modifier metal addition is effective for decreasing the surface silicon oxides and thereby improves the corrosion resistance.

  • Method for tall oil recovery and apparatus therefor
    Patent number: 4347110
    Abstract: A system and apparatus are disclosed for removing particles from suspension in a liquid, particularly for removing tall oil soap particles from black liquor. The black liquor flows along a fluid flow path (10) which runs between a source of black liquor and a skimming tank. Two electrodes (16, 18) are disposed one downstream of the other within the fluid flow path (10). A power supply (26) applies an electrical potential between the electrodes (16, 18). The downstream electrode (18) is connected to earth ground (36). It has been found that this earth ground connection (36) provides substantial improvements in the quality and quantity of recovered tall oil soap.

  • Method and apparatus for photogoniometric analysis of surfaces
    Patent number: 4344709
    Abstract: A method and apparatus for photogoniometric analysis of surfaces is disclosed. A photogoniometric instrument includes a light source (12) for providing a collimated beam of light illuminating a test surface (18). A light detector (20) is mounted for rotation about the point of intersection of the illuminating beam on the test surface. A motor (44) drives the detector through a range of reflectance angles, and a microcomputer (52) digitizes the detector output periodically, storing the digitized data words in its memory (68). These stored words define a photogoniometric curve (FIG. 2A) including a specular portion (FIG. 2D) and a nonspecular, or diffuse, portion (FIG. 2C). A host computer (62) receives the photogoniometric data from the microcomputer, deconvolutes the data into spectral and diffuse portions, and analyzes the two portions separately from one another.

  • Spacebar touch control apparatus
    Patent number: 4343557
    Abstract: A typewriter space bar touch control apparatus comprises a bell crank member, mounted on a support frame, which supports the space bar and a lever member which engages the bell crank when the space bar is depressed more than a small initial displacement. The motion of the bell crank is resisted by a helical tension spring and the engagement of the bell crank by the lever causes an operator to sense a sudden increase in resistance to displacement. Position transducers are provided on the support frame to sense the position of the lever member and the initial small displacement of the space bar corresponds to single space operation and larger displacement corresponds to repeat space operation.

  • Frozen raw custard
    Patent number: 4341808
    Abstract: A freezable raw custard preparation, especially for quiche having a substantial proportion which is whole egg or egg white based whole egg replacer. The composition also has an effective amount of food particulates and a milk derived portion. The egg and milk derived portions are present in a weight ratio of about 0.45:1 to about 0.75:1, the milk derived portion comprising fluid milk, a water absorbing quantity of a protein concentrate, and a thixotropic gum. The total protein content from the fluid milk and protein concentrate is at least about 4% by weight of the milk derived portion. The gum content is that effective to provide a viscosity of the raw custard sufficient for homogeneous suspension of the food particulates prior to freezing.
