Abstract: ABSTRACT OF THE DISCLOSURE A wire line includes a flyer payoff and means for controlling the wire discharged from the flyer playoff by a tension system comprising two spaced tensions, the first of which comprises two groups of rolls with the rolls of one group staggered with relation to the rolls of the other group with the groups relatively movable toward and from each other to apply more or less tension on the wire as it leaves the flyer payoff with the tension system also including a second tensioning means comprising a drum and a guide sheave spaced therefrom about which the wire is passed with sufficient surface engagement with the drum and sheave so that they will rotate as the wire passes thereover rather than the wire slip on either, and then applying a friction drag on the drum to retard the rotation and apply a greater amount of tension before the wire passes on to a point to be serviced.

Abstract: Abstract of the Disclosure Polymerisable compositions comprise a) a compound containing in the same molecule both at least one phenolic hydroxyl group and at least two groups chosen from allyl, methallyl, and 1-propenyl groups, e.g., 2,2-bis(3-allyl-4-hydroxy-phenyl)propane of bis(3-(1-propenyl)-4-hydroxyphenyl)methane, b) a compound containing at least two mercaptan groups per molecule, e.g., pentaerythritol tetrathioglycollate, and c) a heat-activated crosslinking agent for phenol-aldehyde novolac resins. The compositions are caused to polymerise by the action of irradiation or free-radical catalysts. The polymers so obtained, containing more than one phenolic hydroxyl group, can be subsequently crosslinked in situ by heating. The compositions are useful in various two-stage operations, such as the production of multilayer printed circuits.

Abstract: ABSTRACT        An electrical connector for establishing an electrical connection with a fine wire comprises an electrical terminal and an insulating housing having a cavity extending into one surface thereof.  The terminal which is dimensioned to be force fitted into the cavity, comprises a contact arm and a wedge arm beside the contact arm.  The wedge arm is held in slidable relationship with the contact arm.  The electrical connection to the fine wire is established by positioning a portion of the wire in the cavity, inserting the terminal into the cavity with the contact arm extending beside the wire, and sliding the wedge arm along the contact arm so that the wedge arm bends the contact arm towards the wire and clamps the wire between the contact arm and a wall of the cavity.

Abstract: SPECIFICATION OF ROBERT E. SUELFLOW AND EDWARD M. DROBNY                   FOR OUT-OF-CYCLE ERROR CORRECTION APPARATUS             ABSTRACT OF THE DISCLOSURE      This relates to an apparatus and method for providing an accurate data group to the instruction buffer of a data processing system.     The data group is simultaneously applied to the instruc-tion buffer and to error correcting apparatus.  After analysis of the data group in the error correcting apparatus, the operation in progress is aborted if an error has been detected and the error is not correctable.  If correctable, the correct instruction data group is applied to the execu-tion unit.  If no error is tected in the data group, utilization of the data group proceeds uninterrupted.      Two three state busses are employed, the first of which is used to transmit memory data to the error detection and correction (EDAC) circuitry to the data output circuits and to transmit input data to the memory.  The second data bus transmits data to the instruction buffer, to the EDAC circuitry and also transmits corrected data from the data output circuits to the instruction buffer.

Abstract: METHOD AND APPARATUS FOR MONITORING  LINE VOLTAGE IN A POLYPHASE SOURCE     Abstract of the Disclosure A method of monitoring open phase, phase reversal and voltage unbalance conditions in a polyphase source includes shifting the phase of signals which are propor-tional to the line voltages in a three-phase A.C. power source by 180°, +60°, and -60°, respectively, and summing the phase-shifted signals to generate a signal which is proportional to the negative-sequence component of the three-phase line voltage. This signal is rectified and compared with a reference signal. If a net negative-sequence signal is generated over a sufficient time period a positive output signal decreases until it crosses a switching threshold to disconnect a load from the source. The output signal will not rise again to the switching threshold, thereby allowing reconnection of the load, until the negative-sequence signal subsides and is less than the reference signal. A circuit is disclosed with three operational amplifiers and two passive filters to carry out the invented method.

Abstract: ABSTRACT               Improved dispensing apparatus for dispensing machines of the type having at least one dispensing tray containing a dispensing unit which dispenses articles from the machine by the use of a helical dispensing coil.  Improved mounting appa-ratus is provided for supporting both the forward and back end portions of the dispensing coil.  A cross-bracket member having a portion extending across the diameter of the coil, is mounted to the back portion of the coil.  A cross-bracket holding device, connected for rotation by appropriate motor means, releasably accepts the cross-bracket for mounting the back portion of the coil in elevated position above the shelf surface of the dispensing tray.  The cross-bracket holding device is configured to matingly accept differently sized cross-bracket members, to enable rapid interchangeability of differently sized dispensing coils in the machine.  Coil sup-port apparatus mounted to slidably engage the outer circum-ference of the dispensing coil near its forward end supports the forward end of the coil in elevated spaced-apart manner above the tray surface, and supports the coil in a manner which minimizes jamming of the items being dispensed at the forward end of the coil.  Coil compression means mounted adjacent the forward end of the dispensing coil causes the coil to positivel? eject or to impart dispensing motion to the item being dispensed from the convolutions of the coil, during the dispensing rotation movement of the coil.

Abstract: BACK-UP POWER TONGS AND METHOD      Abstract A back-up tong for use with a power tong holds the lower pipe in a pipe joint from being rotated, so as to effect makeup or breakout of the pipe joint.  The back-up tong employs sliding heads which are driven by camming surfaces on a ring-like member fixedly positioned about the pipe, when the heads are arcuately rotated about the pipe. The assembly holding the heads is arranged to be released automatically from the bottom of the back-up tong frame, in the event that the drill string begins to slip back down into the hole, or in the event a portion of the string is prematurely lifted, thereby preventing damage to the back-up tong.  The back-up tong is constructed so that only a minimum amount of clearance is required at the top working surface, thereby permitting the sliding heads to be located as near the joint as possible when simultaneously using a power tong.

Abstract: ABSTRACT OF THE DISCLOSURE             An induction cooking system includes at least one induction surface unit which has an induction coil.          A switching transistor is coupled in series with the coil across a source of rectified AC and is rendered conductive at a prescribed rate to energize the coil, causing the coil to generate magnetic flux, which, in turn causes eddy currents to be circulated within the surface of a metallic, food-containing utensil positioned adjacent to the coil. The circulating eddy currents in the utensil surface result in joule losses , causing food heating. Reactive energy present in the induction coil during intervals when the switching transistor is non-conductive is stored in a capacitor for subsequent discharge across the source of rectified AC.          Selectively discharging the capacitor during the valleys of the rectified AC wave supplied to the induction coil allows the coil to be energized during the entire 360° of the rectified AC wave, thus realizing an efficient induction cooking system.
