  • Patent number: 4517753
    Abstract: A shoe particularly a sportshoe, has a side lacing (1) with a slit (2) extending from an edge (4) of a foot opening (3) toward a toe area at the outside of the shoe over a part of the upper (5) of the shoe, and a tongue (10) covering from below the side lacing, said tongue being according to the invention fastened to the upper with a stitching (11) located within an area extending substantially about a central line (6) at a distance from and along said slit (2), and extending, as seen in the longitudinal direction of the shoe, from the forward end (12) of said slit toward the foot opening (3) over a distance of least one third of the slit's length.

  • Patent number: 4024834
    Abstract: A temperature compensated doctor blade system is disclosed for controlling the amount of liquid on a substrate. Variation in temperature is found to cause wide variation in liquid viscosity which affects doctor blade pressure requirements. An expandable chamber containing a temperature responsive fluid is used to control the pressure applied to a flexible doctor blade.

  • Patent number: 4021655
    Abstract: Size exception detection hardware for use with a digital data processor arithmetic unit for providing high-speed detection of lost data which results from storing an arithmetic result in a destination which is smaller than one or both of the source operands. In response to data processing machine instructions, the arithmetic unit performs arithmetic operations on variable length operands and sends the arithmetic results to variable length destinations. The operand and destination lengths are specified by length fields in the machine instruction. The destination length is specified independently of at least one of the operand lengths and hence may be less than such operand length. The size exception detection hardware looks at both the output field of the arithmetic unit and the destination length field in the machine instruction and generates a size exception program interrupt signal when the part of the arithmetic unit output field located outside of the destination length contains significant data.

  • Patent number: 3937447
    Abstract: The invention is concerned with an injection molding apparatus in which thermoplastic material mixed with an expanding agent is kept in a plastic state below the reaction temperature of the agent and is passed generally continuously through an inter-connecting passage to a transfer cylinder; by flowing through the passage, the mass is heated above the reaction temperature and the built-up pressure prevents foaming of the thermoplastic until it is injected into a mold.
