Abstract: A continuous tubular piece is made in a continuous knit fashion. A limited area, located an equal distance from the two ends of the piece, is knit with a tighter stitch to provide a gathered area. Two similar tighter stitched, gathered areas are provided between the central gathered area and each of the ends of the piece. These two additional gathered areas on both sides of the central area are relatively spaced closer together than their spacing from the central area and the ends of the tubular piece. The tubular piece is folded back on itself using the central gathered area as a fold line, the two opposite ends being brought together. The two additional gathered areas, which were on opposite sides of the central area, are now together, one overlapping the other. A second fold is now made in the piece. The piece is folded back on itself a second time using a point midway between the two additional gathered areas as the fold line. This second fold line is a closed, smooth surface.

Abstract: A lifting ring for a chain sling comprises two generally L-shaped lugs, located on opposite sides of the central plane of the ring body. The upright limbs of the lugs extend partly along the respective sides of the ring body and the lower limbs of the lugs extend partly along the lower side of the ring body towards the central plane. Each lug is provided with an opening of such size and configuration that a chain link can pass through the opening, the width of the opening being less than the width of a chain link whereby withdrawal of the link from the opening when the chain is under tension is prevented by the adjacent link at right angles thereto.

Abstract: A device for attaching on a spectacle lens a block for mounting on a lens edging or bevelling machine comprises fixed mounting block holding means, lens holding means located substantially in one plane and movable between a rest or centering position, in which the lens to be blocked is at a distance from the mounting block and a blocking position for securing the mounting block on the lens. This device further comprises centering marks located substantially in the plane formed by the lens holding means when no lens is placed on said holding means. The centering marks are movable in a direction substantially perpendicular to said plane in such a way that they are always in contact with the surface of a lens placed on its holding means, said surface being the surface adapted to receive subsequently the mounting block.

Abstract: A method and apparatus for mixing fuel and an oxidizing agent includes an electrically charged electrode which forms an electrostatic field through which a stream of fuel is passed so that the fuel particles become electrostatically charged and subsequently repel one another to disperse into and mix with an oxidizing agent and vaporize on contact with a heat source such as the wall surface of an intake manifold of an internal combustion engine or the walls of fuel burning apparatus, or combustion chambers of jet or rocket engines and the like. Fuel particles passing through the electrostatic field are charged by induction charging and in addition may also be electrostatically charged by direct contact with the electrode, which is provided with an open outlet end to permit a relatively unobstructed flow of intermixed fuel and oxidizing agent with a minimum of flow resistance and little possibility of ice formation.

Abstract: A programmable control for load management of a plurality of electrical power loads is disclosed which contains at least two groups of load controllers for controlling the power supply to loads connected to various pre-selected load controllers. A group selector selects which of the groups is functionally operative at any given instant in time based on environment or other criteria. A serial selector commonly connected to each of the load controllers in the groups serially selects one of the load controllers in each group for conduction for at least one period of the serial selector. There is provided a first set of programming points situated at the input to the load controllers. The programming points are selectively connected by wires or diodes in any desired fashion to modify the conduction period or order of the various load controllers.

Abstract: Disclosed is a touch operated capacitance switch which may be used in connection with a digital arpeggio system for an electronic organ that through the use of digital techniques permits arpeggios, note sequences as well as strum, multi, organ, and normal modes of operation to be played automatically. Two counters scan by counting through an 8.times.8 matrix of 64 words covering the 61 notes of an organ in rapid sequence upon the playing of one or more organ keys. Each word is fed to a corresponding one of 61 decoders, one for each note of the keyboard. If a corresponding key has been played, the decoder provides a signal to a corresponding pulser circuit which enables a corresponding keyer to transmit an audio signal from an audio oscillator corresponding to the played key to an output system and loudspeaker.

Abstract: A fuel supply device comprising auxiliary throttle means located in the intake pipe upstream of an operator actuatable throttle means and a source of pressurized fuel comprising a delivery circuit which opens into a portion of the intake pipe downstream of the main throttle means, the delivery circuit being controlled by at least one solenoid valve. A metering system, which is sensitive to the degree of opening of the auxiliary throttle means, has means supplying repeating pulse signals. The metering system supplies the solenoid valve with one energization signal per pulse signal repetition period which has a duration equal to a fraction of the period which is adjusted by the metering system. The source of fuel has a pressure regulator comprising a relief valve which is biased toward opening by the fuel delivery pressure and toward closure by the vacuum in a chamber connected to the intake pipe. The chamber is bounded by a diaphragm, to which the closure member of the valve is connected.

Abstract: One component, such as a rear cowling of a turbojet engine nacelle, is held o another component, such as a flange of the engine housing, by a plurality of lockbolts. The lockbolts are synchronously controlled to effect attachment or detachment of the cowling or other component. Each lockbolt includes a strap which may be fixed with respect to the stationary component such as the flange. Each lockbolt also includes a tie bar having a hook at one end for cooperation with the associated strap and a pivot shaft at the other end. The pivot shaft rides in a slide track which may be disposed in a second support attached to the removable component. There is a moving part which may be carried by the second, stationary support, the moving part including a cam which cooperates with the pivot shaft of the tie bar to impart translational movement to the tie bar. The cam has a dwell portion which enables the moving part to move beyond the position at which the hook of the tie bar is fully withdrawn.
