Abstract: A shoe having a sole, an upper formed from a relatively soft and extensible material, a lacing strip and a bandage connecting the lacing strip with the sole. The bandage is formed from a material which is less extensible than the material of the upper. The bandage includes an elongated portion and a connecting portion which extends laterally of the elongated portion at the juncture of the bandage with the lacing strip. The laterally-extensive connecting portion transmits forces from the lacing strip to the elongated portion, and substantially prevents transmission of such forces through the extensible material of the upper. Thus, the upper is less apt to become fatigued or distorted during wear. This abstract should not be taken as a complete exposition of the present invention.

Abstract: In drawing glass fiber from a glass melting furnace to form a multiplicity of filaments which are first divided and formed into a plurality of strands which are then wound on a single spindle to form a plurality of square-ended packages thereon, the strands are shifted to a front waste take-up portion of the spindle by means of a guide which is moved from the rear end to the front end of the spindle across the paths of movements of the strands when the packages are fully wound, to enable the fully wound spindle to be replaced by a new spindle without interrupting the drawing of glass fiber. The spacing between the spindle and the path of travel of the guide and the speed of travel of the guide are set at a low level and a high level respectively which are sufficient to ensure at least loose portions of the strands, which are produced when they drop into the groove between the adjacent packages, to be immediately wound on the peripheral surface of the adjacent package.

Abstract: A knife apparatus comprises an elongated handle member formed with a groove of a C-like cross-section, a slide unit disposed longitudinally slidably within the groove, and a blade slidably disposed in the groove and having a base portion connected to the slide unit. Locking member is provided for the slider unit and adapted to mesh with a tooth train formed in at least one longitudinal edge of the groove, to thereby immobilize the slide unit and hence the blade relative to the handle. A manipulator plate having a cam groove is disposed on the slide unit over the locking member to control the locking member, whereby the slide unit is moved between the locked and the released positions under the control of the manipulator plate.

Abstract: An instantly variable constant current control is interposed between a bank of batteries and a motor. The variable constant current control comprises a series pass transistor operating in a linear mode and controlled by a reference voltage from a potentiometer coupled to an accelerator pedal. Correction voltage from the series pass transistor circuit is proportional to current. The accelerator reference voltage and the current correction voltage are compared in a linear operational amplifier which controls the "on" resistance of the series pass transistor.

Abstract: A grain sorter including a machine frame, at least one grain sorting board and a device for moving the grain sorting board in swinging movement including a mounting mechanism for mounting the grain sorting board on the machine frame in such a manner that the grain sorting board is inclined in one direction at a certain angle of inclination with respect to the horizontal, a swinging mechanism for moving the grain sorting board in swinging movement at an angle larger than the angle of inclination of the grain sorting board, and an adjusting mechanism for adjusting the angle of inclination of the grain sorting board. The mechanism for adjusting the angle of inclination of the grain sorting board is incorporated in the device for moving the grain sorting board in swinging movement within the limit set by the heights of the mounting mechanism and the swinging mechanism, so as to lower the center of gravity of the grain sorting board and avoid production of irregular vibration of the grain sorting board.

Abstract: A method of correcting retinal detachments through a small conjunctival incision wherein an expandable member is inserted into Tenon's space, the member is expanded, to form an indentation in the eye, and left in place until the subretinal fluid has absorbed and the retina has reattached.

Abstract: In extrusion apparatus of the type having a generally cylindrical roller, a stationary die head surface confronting the roller and defining therewith an extrudate chamber, and means for rotating the roller to force material through the chamber to an extrudate shaping orifice defined by the roller and a downstream portion of the die head, a bearing pad is interposed between the roller and the die head. The roller is biased against the bearing pad so that the pad serves to space the roller from the die head to accurately control clearance between the die head and roller at the extrudate shaping orifice.

Abstract: Apparatus for exposing a series of plates to radiation. A stack of plates 53 to be processed are placed on the surface of a first table 7 located adjacent to a second table 8. Radiation exposure means 31 above both tables are switched on and after a time equal to half the required exposure time for a single plate a carriage 45 moves to slide the top plate of the stack from the first table 7 to the second table 8, deflecting a switch operating member 52 against a biasing force. This member operates a switch causing a motor 27 through suitable transmission systems to raise the first table 7 and lower the second table 8 by equal distances until the switch operating member 52 returns to its original position under the biasing force.

Abstract: An automatic control system for a hulling machine including a fixed rotary hulling roll, a movable rotary hulling roll, means for moving the movable rotary hulling roll toward and away from the fixed rotary hulling roll to adjust the gap between the two hulling rolls and a main electric motor for driving the two hulling rolls. The system includes load detecting means for detecting the load applied to the main electric motor, and control means for connecting the load detecting means to the means for controlling the movement of the auxiliary shaft whereby the gap between the two hulling rolls can be automatically adjusted in accordance with the load applied to the main electric motor.

Abstract: A location transmitting system for use by one or more guards in a security system. Encoders are located at predetermined reporting locations which have no power supplies. Each guard carries a walkie-talkie radio transmitter which he places in a receptacle at the reporting location, energizing the encoder through external terminals in the receptacle which mate with external terminals of the walkie-talkie and its power supply.

Abstract: An arrangement of electric motors which are coupled together both mechanically and electrically comprises series pass elements and current sensing devices in the power circuits of the respective motors, each current sensing device having an output voltage which is proportional to its motor current, and which is applied to a respective linear operational amplifier having an output which controls the equivalent resistance of the series pass element (and thereby the magnitude of motor current). A single reference voltage is applied to all the linear operational amplifiers, so that, for example, if the motors are similar, each will transmit the same torque regardless of any difference in its internal impedance.

Abstract: A steel belted radial ply tire construction characterized by an improved cap ply is disclosed. In the finished tire, a cap ply is formed from at least one layer of rubberized yarns of synthetic filamentary textile material. The cap ply is disposed in direct surrounding relation to the radially outermost belt ply of the tire. Since the cap ply is formed from single yarns rather than cords, the cap ply is thinner than conventional cap plies, has superior flexibility and heat dissipation characteristics. This abstract is not to be taken either as a complete exposition or a limitation of the present invention, the full nature and extent of the invention being discernable only by reference to and from the entire disclosure.

Abstract: An automatic safety device for a hulling machine comprising a housing, a fixed hulling roll and a movable hulling roll forming a pair rotatably mounted parallel to each other in the housing, means for driving the two hulling rolls and means for forcing the movable hulling roll to move toward the fixed hulling roll. Each hulling roll has fitted thereover a metallic annular member and a resilient annular member in the indicated order. The automatic safety device includes detecting means for detecting that at least one of the resilient annular members of the hulling rolls has reached a predetermined wear limit radius, and a safety control electric circuit connected to said detecting means and including warning means and/or means for interrupting the operation of the means for driving the hulling rolls.

Abstract: A pneumatic radial tire has a two-ply tread reinforcing breaker wth cords of filamentary material. The breaker plies are of unequal widths and arranged symmetrically with respect to the median circumferential or equatorial plane of the tire, the overall width of the breaker being substantially the width of the overlying tread. In the region of each shoulder of the tread, the edges of one ply are folded back on themselves forming superimposed two-ply regions and three-ply regions enclosing the edges of a narrow, non-folded ply. Surrounding each two-ply region of the folded ply is a cushion rubber which is softer than the tread or breaker skimcoat rubbers. The breaker construction substantially eliminates breaker edge separation, resulting in a more durable radial tire which can be recapped to provide further service.
