  • Patent number: RE30534
    Abstract: Electronic flash apparatus for a camera having automatic focusing with sonic ranging has a charge control system which inhibits charging of the flash tube capacitor during at least the automatic focusing operation of the camera. The flash apparatus thus schedules capacitor charging to occur at times other than the sonic ranging for automatic focusing, and thereby avoids the likelihood that spurious radiation from the capacitor-charging oscillator interferes with the sonic ranging operation.

  • Patent number: RE30535
    Abstract: An improved developing device in electrophotographic copying apparatus in which a plurality of developing electrodes are disposed along a path of movement of a photosensitive drum surface. The electrodes are applied with voltages in a graded manner which conforms to the damping characteristic of the potential on the photosensitive surface at a developing station. The values of voltages applied can be controlled in accordance with the value of potential formed by an imaging area of the drum surface while maintaining the graded potential to thereby achieve an excellent developing effect. Further, the drum surface is provided with an unexposed and hence high potential portion which serves to remove toner which accumulates on the electrodes.

  • Patent number: RE30536
    Abstract: An ultrasonic hand-held cleaning device having a housing enclosing a casing, an energyzing winding about the casing, and a fluid conduit attached to the interior of the casing. A sleeve is insertably mounted into the end of the casing, and acts to support a connecting body at a spaced distance within the sleeve so as to form an annular space in fluid communication with the casing. A vibrator is attached at the casing end to the connecting body and is therefore located in the casing opposite the energyzing winding. A cleaning tool is attached at the other end of the connecting body. In one version fluid moving through the annular space is sprayed out an annular nozzle around the tool which is itself vibrating ultrasonically as a result of reverbretory vibrations induced by the vibrator. In a second preferred embodiment the connecting body has a ring at its nodal point, the sleeve being cut out to accommodate the ring and having two longitudinal slots for the passage of fluid.

  • Patent number: RE30537
    Abstract: A low wash and rinse temperature (120.degree.-140.degree. F.) warewasher accomplishes the same general washing and rinsing effectiveness as a conventional high temperature (150.degree. F. minimum wash, 180.degree. F. minimum rinse) warewasher without loss of productivity resulting from time lost between completion of washing and commencement of rinsing a given load of ware, through use of independent, dedicated wash and rinse systems, the latter of which includes a holding tank which enables independent batching of a predetermined volume of rinse solution from properly-proportioned fresh water and sanitizing agent while washing a given load of ware. The sanitizing agent is introduced independently into the holding tank and independently of the fresh water line, and is therefore unaffected by a great range of water line pressures and the mineral conditions of the water.

  • Patent number: T100402
    Abstract: A method and means for modifying up to k bits in each byte of (n+k) bits to be accessed with respect to counterpart minor loops of a sequentially accessed byte-organized major/minor loop memory array. The combination of bad byte location pointers and a byte mask is used to delete bits on bad bytes extracted from the memory or to insert zeroes into defective loop locations when bad bytes are written into the memory. Alternatively, the ith bit in each byte of (n+1) bits to be accessed may be modified through the utilization of the value of the ith bit written into the byte position of n+1st bit, while the ith bit of a defective byte position is zeroed. As a bad byte is extracted, the value of the n+1st bit is substituted for the ith bit. A dense list, rather than a sparse bad byte pointer list, is used.

  • Patent number: T100405
    Abstract: A powdered orange flavor containing 27 fold orange oil adsorbed on rice sch was prepared by a menthol treatment process. The powder contained the equivalent flavoring potency of 18% by wt. of whole orange oil, which was the maximum obtainable; other rice starch samples contained lesser amounts and had lower folds. Two other edible polymers, egg albumin and Mor-rex (hydrolyzed cereal solids), also had some capacity, when treated with methanol, for polar orange oil components. These were less suitable than starch, however, because of inadequate concentration on the polymer, a low degree of folding, or distorted oil compositions.

  • Patent number: 4253201
    Abstract: An inflatable, implantable prosthesis includes a flexible, inflatable, thin wall container of physiologically acceptable material provided with a self-sealing valve assembly which permits fluid to be introduced into or removed from said container to inflate or deflate the prosthesis. The self-sealing valve assembly includes a top having an outer wall and an inner wall which are sealed about their periphery to form an envelope which is filled with a self-sealing gel. The outer wall of the top is secured to the inside of the container and a side wall depends from the top and is connected to a bottom to define a chamber. The chamber has at least one opening in the bottom or side wall so that inflating fluid can pass to and from said chamber into the interior of the container.

  • Patent number: 4253202
    Abstract: A wave gutter for swimming pools that automatically positions and maintains a longitudinal edge of the gutter, relative to the waterline, for optimum control of waves and other surface disturbances created by persons in the pool includes a wall member, fabricated to be buoyant in water, that is hingedly attached to a sidewall of the pool. The wall member is free to pivot about an axis that is proximate to and parallel with one of a pair of longitudinal edges of the wall member. This freedom, together with the buoyancy of the wall member, allows the other longitudinal edge to be situated substantially at the waterline for the most efficient wave damping capability.
