Filed: 1940-05-28
Abstract: 567,636. Cooling radiators for aircraft and motor vehicles. WAREING, R. J., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. May 28, 1940, No. 9360. [Class 64 (iii)] In an oil cooler having a byepass through which the oil flows when over-cooled, all the entering hot oil is directed through a jacket 3 or through a conduit extending the whole length of the cooling matrix before entering the matrix and its associated byepass. Hot oil flows from inlet 5 through jackets around matrices 1, 2 into a chamber 17 and, if the oil in the matrices is cold, it exerts a back pressure to flow and opens a pressure-responsive valve 16 to allow the hot oil to pass from the chamber directly to the outlet pipe 18. As the oil in the matrices warms up, its resistance to flow decreases and the valve 16 closes, and most of the oil in the chamber 17 then flows through a thermostatically-operated valve 19 to a conduit 20 leading to the matrix 1, thus byepassing matrix 2. When the oil in the outlet conduit 18 reaches a predetermined temperature, the valve 19 is closed and all the oil is forced to flow through the matrices 2, 1 in turn.

Title: Improved means for reversing sacks, sheets and the like applicable to printing and other machines
IPC: B41F21/00
Filed: 1927-04-06
Abstract: 288,811. MacDonald, D. J., and Mac- Donald, Ltd., D. J. April 6, 1927. Delivery apparatus; gripper mechanism.-Relates to mechanism for reversing sacks, sheets, or the like, chiefly applicable to printing- machines to enable the sack &c. to be reversed after printing on one side, for printing on the other side in a second machine. The mechanism is carried by a rigid framework consisting of sidemembers a mountec. on feet d adapted to be secured to the bed of a printing-machine. An endless chain passes round sprocket wheels f, g, on each member a, the wheels g being continuously driven from, and in timed relation with the printing machine. Gripper bars m carried by arms s are freely pivoted to the chains at distances apart equal to the length of the circumference of the printing-cylinder k. The gripper bars are normally held together by springs z acting between extensions v of the arms s, and the extensions v carry pins w, one of which runs always in a track x on the adjacent member a, and the other is adapted to engage a track y. The sack printed on one side by the cylinder k is fed by an endless band n to the grippers as they pass round the wheel g, the bars m being opened at this point as a result of the engagement of one of the pine in the track y. On leaving the track y, the grippers are closed by the spring z and carry the sack upwards. The grippers are upwardly-directed until they strike a stop 2 when they are turned on their pivots, the track x being curved to enable this to be done. The grippers remain in the downwardly-directed direction as they pass over the wheel f, and are opened again to release the sack &c. by the engagement of the pin w with the track y. The framework is directed rearwardly, so that the sack &c. hangs clear of the chains. The sack is delivered to a travelling belt 3 by which it is carried to the second printing- machine.

Title: Method of and means for controlling the driving of spindles in machines for winding thread, yarn and such like
IPC: B65H59/38
Filed: 1937-04-05
Abstract: 492,053. Yarn - winding machines. AYRTON & CO., Ltd., W., and OSBORNE, F. April 5, 1937, No. 9541. [Class 120 (ii)] The shifting mechanism of the belt connecting the speedadjusting cones in the driving mechanism of a machine for winding thread, yarn and the like is held by a ratchet and detent ; the detent is released at intervals by operation from the cam box as the package diameter increases so that the belt is shifted to reduce the speed of the spindle carrying the package. This arrangement avoids the transmission of vibration and belt pull to the yarn guides. Two spindles b, b<1>, used as described in Specification 438,739, are shown, and are driven by a belt i<1> through variable speed mechanism consisting of reversed cones f, g connected by a belt e which can be shifted by the structure e<1> sliding upon supports e<2>. This structure e<1> is connected by a link e<3> to a lever h attached to a shaft h<1> in bearings h<2> ; the shaft is also attached to an arm k which carries a bracket k<1> supporting a toothed quadrant or rack m. Both the bracket and the quadrant are adjustably mounted. A detent n3 is mounted in a boss n<2> on an arm n<1> which moves with the cam box a and can be manually operated by means of the handle n. The point h3 on the lever h is joined by a flexible connection h<4> to a weight h<6> which tends to move the belt shifting mechanism to reduce the speed of the spindles b, b<1>, and the point j<1> on the lever h is connected to the treadle j<7>, depression of which pulls the belt shifting mechanism back to zero against the pull of the weight h<6>. The cam box a has yarn guides c, c<1> bearing on the windings and as these increase in diameter the detent n<3> is lowered until it is disengaged from ratchet tooth, and the weight h<6> moves the lever h, the arm k, and the quadrant m forward until the next tooth is stopped by the detent. This movement causes the belt e to be shifted to diminish the speed of the spindles.
