A tape reading-out system comprising a tape driving means equipped with a clutch having rotary shafts for allowing a tape stored with information to be moved forward, means for detecting signals directing the travel and stop of said tape from the displaced rotation of the rotary shaft of said clutch and a circuit enabling the rotary shafts of said clutch to rotate or stop and controlling the reading of information out of the tape by controlling the operation of said clutch using said detected di...

A snap-out set in the form of a unique structural arrangement of an original top sheet and one or more copy sheets. The top sheet has a quality and density meeting the requirements of the scanning apparatus in an optical character reader and is provided with preprinted spaced guide lines (bars) and line designations to enable the typist to visually align message information, for example type characters within certain area limits; for example, an indicia receiving area. The message information or...

A valve structure comprising a swing-out body which is clamped between line flange connector plates by means of elongated studs with clamping nuts. Those studs which are located on, and on one side of, a diameter of the flow passages are provided with jacking nuts which may be tightened to engage the inside of the connector plates and separate them out of clamping engagement with the swing out body. A pair of hinge members welded to the swing out body have circular openings therein which rotatab...

A feed-out device for extracting the leading end of a strip wound on a cassetted reel has a stripper hinged to the forward end of a support, which is inserted into the cassette during feed-out. The support is provided with a bearing surface which engages the strip roll periphery, and the stripper is biased resiliently to engage the roll periphery -- thus irrespective of the size of the roll, the thrust of the stripper against its surface and its angle of attack remain substantially constant.

An information carrier includes a base carrying information indicia having physical properties differing from those of the base. The indicia are arranged on the base in a manner such that, during a read-out operation, each indicia is detected twice by a detector. The carrier may comprise a circular transparent base having annular indicia thereon, the indicia being either transparent or nontransparent. A slicing circuit and a shaping circuit connected to the detector provide first pulses specific...

A conventional decoder of the type that converts an m-out-of-n representation to activation of only a single one of plural output lines is modified to have powerful self-checking capabilities. The modified decoder is adapted to be included in a control system in which the words stored in a microprogram memory are coded in an m-out-of-n format. Such a system automatically detects the occurrence of any no-output or multiple-output readout from the memory.

A collapsible compartmented tubular carry-out tray is formed from a cut and scored blank of paperboard and comprises spaced and parallel top and bottom panels hingedly connected to spaced parallel side wall panels to define a tube. Prior to forming of the blank into a tube, the top panel is provided with apertures adapted to receive cups or the like and a single larger aperture for a larger sized article. The formation of said aperture is concomitant with the formation of partition structure ext...

A push-out apparatus adapted to be attached to a ladder for moving the ladder to a selected adjusted position relative to a surface against which the ladder is supported. The push-out apparatus includes a ladder attachment assembly having releasable connecting means for securing the assembly in a set position on the ladder and for permitting ready removal of the assembly from the ladder. The push-out apparatus includes push-out means supported on the attachment assembly for movement relative the...

A carburetor assembly having primary and secondary induction passages or bores with primary and secondary throttle valves respectively situated therein and a choke valve in the inlet of the primary induction passage, has linkage means interconnecting the primary and secondary throttle shafts and valves so as to enable the opening and closing thereof in response to operator demands; additional thermostatically controlled latching means are provided so as to prevent the opening of the secondary th...

Method and apparatus for removing underwater well pipe connected below the mudline by washing out mud surrounding a portion of the pipe. The method utilizes a special joint which comprises two tubular members engageable with each other, one of which has wash out ports through its walls. A sleeve member is mounted in the tubular members for longitudinal movement from a first position where it blocks flow through the wash out ports to a second position where it permits such flow. The sleeve member...
