Title: Improved method of and apparatus for cleaning heat exchange means
Inventor: KIRKBY ALBERT HARRY
IPC: F23J3/02
Filed: 1954-11-23
Abstract: 772,508. Cleaning pipes. BABCOCK & WILCOX, Ltd. Nov. 22, 1955 [Nov. 23, 1954], No. 33906/54. Class 99(2) Cleaning particles are introduced into a gas pass 1 containing vertically-spaced banks 4 ... 4C of heat-exchange tubes arranged horizontally in staggered formation. The particles are projected from discharge tubes 8 ... 8C situated between the banks so that the tubes near the bottom of the pass are acted on more strongly than those at a higher level, the density and time of action of the particles acting on a lower bank being greater than that on a higher bank. To increase the area over which the particles are scattered, an oscillating, deflector plate may be. provided. In Fig. 1, the particles falling through the pass 1 are collected in a duct 10 provided with means for removing pieces of slag and particles below a predetermined size, a shoot 19 delivering the remaining particles to a bin 20 having an overflow spout 22 and a hopper 11 provided with outlets connected to nozzles 13, all as described in Specification 745,556. Cut-off valves, 12 as described in Specification 745.620 [Group XXX] are provided also. The nozzles 13 are connected to a source of gas under pressure by pipes 15 ... 15C and to the discharge tubes 8 ... 8C by pipes 16 ... 16C and flexible hose 17 ... 17C, a valve 14 being provided in each pipe 15 ... 15C whereby any discharge tube may be put out of action. The discharge tubes are downwardly inclined and each carries a deflector plate 9, which, as shown in Fig. 3, comprises a detachable plate 28 mounted oh a back plate 26 carried by an arm 25 removably connected to the tube 8 by a split sleeve 27. In Fig. 5 (not shown), a second plate having a curved impact face is provided opposite the plate 28. to effect a wider dispersal of the particles, and in Fig. 6 (not shown), a curved plate is carried by a bracket bolted to a slotted arm at an adjustable position. Additional tubes may be provided at each station either alongside or opposite the tubes 8 ... 8C. Fluted impact faces may also be used. Fig. 8 shows mechanism for oscillating the discharge tubes. A tube carrier 44 is oscillated about an axis 47 by a crank 55 connected to' a bell crank 59 connected to the carrier by a rod 63 with ball joints 62, 64, and oscillation about the tube axis is ejected by a crank 53 connected to a boss 49 fixed to the tube. Specifications 715,935 and 726,744 also are referred to.

Abstract: 472,212. Exhaustsilencers. SCHOSLER, R. C. A. Dec. 14, 1936, No. 34346. [Class 7 (ii]) Staggered apertures in the telescopicallyarranged casings of a, silencer comprise pairs of adjacent slots 3, 4 located at suitable angular intervals in each casing and extending along the length of the casings ; the adjacent slots are formed by countersunk walls 5 and the gaseous currents impinge on one another as they issue. In the construction shown in Fig. 2, a central duct 2 is connected to the engine exhaust by a pipe 1, the duct having a longitudinally-spaced series of apertures 3, 4. Around the central duct 2 is a primary casing 6 with apertures 3a, 4a formed therein and staggered relatively to those in. the central duct. Encompassing the primary casing 6 is a secondary casing 7 having at its fore end a forwardly tapering cowl 8 formed with curved or oblique slots 3b, 4b of similar form to those in the central duct and adapted to impart a helical motion to the gases passing therethrough. The rear end of the secondary casing 7 is closed by a pointed member 9 attached to the central duct 2 by a screwed rod 10. Around the secondary casing are arranged a number of tubes 12, 14 ... 17, the outer one 12 of which is closed at its fore end and is so shaped as to allow the surrounding air to flow over it easily. The tubes 12, 14 ... 17 are formed at their rear ends with outwardly turned edges 13, 18 ... 21 which deflect the air or gases flowing past them and produce a suction which facilitates the discharge of the gases. An air shaft 22 is arranged outside the tube 12 and may be formed with air inlets 24 and an outwardly-turned rim 23.

Abstract: 1,010,886. Spray carburetters. FORD MOTOR CO. Ltd. Aug. 24, 1964 [Sept. 3, 1963], No. 34450/64. Heading FIB. The stroke of an accelerating pump operated through resilient vanes from the throttle valve is reduced as temperature increases. A throttle operating lever 24 is connected to a pump operating lever 38 through a torsion spring 39, lever 38 being connected by a rod 44 to the pump operating lever 35 provided with ratchet teeth 55 co-operating with an abutment 49 formed by a bimetallic strip. At low temperature the abutment 49 is bent inwardly to the left so that the lever 35 is moved through a full stroke when the throttle valve is opened. As temperature increases the abutment 49 moves to the right to a position to engage one of the teeth 55 during the movement of lever 35, thereby halting the lever 35 before its stroke is completed, the spring 39 acting as a last motion device during the remaining opening movement of the throttle lever 24.

Abstract: 646,397. Cylinders. PESCARA, E. P. Dec. 29, 1947, No. 34477. Convention date, June 23, 1942. [Classes 7(ii) and 7(iii)] The exhaust passages of the outside pairs of a row of cylinders having overhead valves, are combined in passages 87, 88 leading between the inlet valves 1, 2 and 3, 4 respectively and to the' side of the cylinder head. The inlet passages 59, 60 and 64 of cylinders firing at 180 degrees are connected to a double downdraught carburetter 62, 67, a flap-valve, not shown, cutting off the carburetter 67 until the throttle valves mounted on a common spindle 84 are nearly open. Lost-motion in the linkage allows the throttle valves to commence opening until the resistance of a spring-pressed ball on a groove in the spindle 84 has been overcome when the flap-valve quickly separates the two carburetters. The Specification as open to inspection under Sect. 91 comprises also independent throttle valves, one being opened through a bellows device by suction in the induction pipe when the resistance of the spring- pressed ball has been overcome. This subject-matter does not appear in the Specification as accepted.

In. a servomotor of the kind described in the parent Specification, the reaction means is modified to replace the fluid in chamber 82 by a deformable body 86, e.g. of rubber or an elastomer, which, on pressurization, deforms to move a reaction pin 98 against the control member 56 with a force proportional to that transmitted between piston C and member D, the head 96 of pin 98 being held against the body 86 by a spring 94 in a sleeve 88 clamped by flanges 90 between the body 86 and the chamber 82. The end of the pin 98 is spaced from an abutment 104 in bore 102 of member 56, this spacing and the strength of spring 94 opposing deformation of body 86 permitting the pressure in master cylinder A to be built up to, say, 100 p.s.i. before the reaction-pin 98 is moved against member 56. In Figs. 2 and 3, not shown, the body 86 is replaced by a liquid-filled pliable bag and by a liquid-filled metallic bellows respectively; and in Fig. 4, not shown, the reaction pin is formed integral with member 56, the pin being spaced from the deformable body.

Title: Automatic workpiece handling systems for machine tools
IPC: B30B15/14
Filed: 1977-08-17
Abstract: The work-transport apparatus has a feed device for transporting workpieces, in particular metal sheets, stacked in a supply magazine (50) to a working table (15) of the machine tool (10) as well as an unloading device for transferring the workpieces (WP) into a deposit magazine (51). On the working table (15), the workpieces are seized by a gripping and moving device and are accordingly positioned for working, for example for punching. The initial position of the workpieces on the working table (15) is detected by sensors. The positioning is effected by a numerical control device (30). Such an apparatus permits automatic operation of the machine tool, in particular a turret punch press, including the transport of the workpieces from magazine to magazine and in addition guarantees positioning of the workpieces independently of the feed. <IMAGE>
