Abstract: 1421216 Tubular heat exchangers SAAB-SCANIA AB 7 Sept 1973 [13 Sept 1972] 42267/73 Heading F4S A heat exchanger comprises spaced-apart strip fins 13 which extend through and beyond the cross-section of heat exchange tubes 11 (i.e. both internally and externally of the tubes), the tube cross-section having an internal dimension wider than the fin width so that flow passages are formed on each side thereof for the internal fluid 3 which in use flows first through the tube portion 16 and then between the fins to the tube portion 17, whilst the external fluid 6 flows over the tubes between the external parts of the fins. The intention is that heat transfer between the fluids 3 and 6 is mainly via the fins 13 which are of metal foil whilst the tubes themselves can be made of a plastics material. Preferably the aforesaid flow passages provided by the tube portions 16 and 17 are of gradually decreasing and increasing cross-sectional area respectively in the direction of fluid flow, as indicated in Fig. 4.

Title: Improvements relating to control apparatus for use with power presses and similar machine tools
Inventor: DEYKIN RONALD FREDERICK
IPC: B30B15/14
Filed: 1960-12-15
Abstract: 1,005,182. Controlling clutches and brakes; machinery guards. HORDEN, MASON & EDWARDS Ltd. Dec. 14, 1961 [Dec. 15, 1960], No. 43139/60. Headings F2J and F2L. In a control apparatus where the change from one setting to another is determined by electrical means in which a holding current retains the apparatus in one setting, change to the other setting is produced by reducing the current to a value below the holding current and reversion to the first setting is produced by raising the current to a value higher than the holding current. A power press is driven by a 3-phase electric motor, having windings A, B, C energized through reversing switching from lines t 1 , t 2 , t 3 , through clutch and brake units engaged, through an intensifier, by a solenoid-operated air valve 12. A low voltage direct current supply circuit 13 incorporating a storage and smoothing capacitor C3 supplies a pulse-forming circuit incorporating a capacitor C1 and a timing resistance R2. For single cycle working, the capacitor C1 provides a current pulse of pull-in value to set the air valve 12 to run condition, which pulse reduces early in the cycle to a holding value supplied from the circuit 13; the holding current being broken near the end of the cycle by a switch 53a, driven from the press shaft, to reduce the current to a drop-out value and allow the valve 12 to return to the inoperative condition, disengaging the clutch and applying the brake. For continuous running the switch S4b short circuits the switch S3a and allows flow of holding current until switch S4 is returned to its original condition, whereon the press stops in the predetermined open position. Operation of emergency stop switch S7 will stop the press in the immediate condition. A third capacitor C2 under control of a switch S5 provides for inching, which does not have holding current conditions, the time of clutch engagement being determined by the time constant of the discharge circuit for the C2 capacitor as preset by the resistance R2. In a modified control circuit for a press having a guard, the function of the treadle switch S1 is performed by the treadle switch and a guard operated switch, and a selector switch bank is incorporated to permit working on single cycle, continuous run, treadle operation, guard operation, or interlock of treadle and guard. Specifications 941,306 and 1,005,183 are referred to.
