Abstract: 1,228,223. Pipe bends. SIMON-CARVES Ltd. 15 Sept., 1969 [1 Nov., 1968], No. 51941/68. Heading F2G. A pipe bend has, at least in the vicinity of the outside of the bend, a plurality of internally located ribs which extend longitudinally of the pipe bend. In the embodiment described, eight rectangular-section, radially projecting ribs are evenly spaced around the whole of the inner wall of the pipe bend and are integral with it. The ribs oppose the formation, by centrifugal forces, of closed loop systems of secondary flow. They are particularly useful when a two phase mixture, e.g. a steam/water mixture is transported, as they ensure maintenance of annular flow, the water forming a continuous film over the entire internal surface of the pipe. The surface on the outside of the bend, which would otherwise be dry, is thereby protected from collision with droplets of water, thus reducing errosion and/or corrosion.

Abstract: 1,252,512. Percussive tools. GARDNERDENVER CO. 20 March, 1969 [26 Sept., 1968], No. 14833/69. Heading B4C. [Also in Divisions E1-E2] A down-the-hole percussion drill comprising a hammer piston 21 which delivers blows to the shank 32 of a bit 30, has a multipassage tube 72 extending from a discharge bore 76 to a pressure fluid inlet 44; the tube 72 has a conduit 98 to conduct fluid to a drive-chamber 26 for lifting the hammer piston between strokes, passages 81, Fig. 3, having ports 84, 86 to exhaust motive fluid from drive chambers 24, 26 and a conduit 92 to by-pass fluid from the inlet to flushing ports 88, 90. The drill is attached to the lower end of a rotatable drill pipe 12 through which pressurized fluid (air) is supplied. The tube 72 has a partition 82, containing the conduits 92, 98 and defining the passages 81. In operation, air from the inlet enters the chamber 24 through conduits 60 and 114 to drive the hammer piston downwards. Air from the chamber 26 is thereby displaced into a space 104 and through a port 110 in the conduit 98 and passes out through a port 102 into a chamber 100 to depress a valve member 66 which closes the conduit 114. As the descending hammer piston uncovers the ports 84 the air in the chamber 24 is exhausted to the exterior. Air then passes from the inlet and the conduit 60 to the chamber 100 and down the conduit 98 into the chamber 26 to lift the hammer piston for the next stroke. The air in the chamber 26 is exhausted to the exterior as the rising hammer piston uncovers the ports 86. The by-pass conduit 92 may contain a constricting plug 94 having a suitable diameter bore 96. When the drill is lifted from the hole bottom, the bit and hammer piston fall until lugs 34 engage a seating 36 so that the port 110 is covered by the part 120 of the shank, and a port 112 is uncovered, thus preventing reciprocation of the hammer piston and ensuring that all the air passes to the flushing ports.

A cover piece 36 is also secured to the elongated member 2 between the bracket members 18, 20 in their closed positions to thereby form a substantially continuous elongated surface over the elongated member 2 which has the overall appearance of a trim strip. Spring members 50, 52 urge bracket members 18, 20 towards their open position but U-shaped spring clips 56 are used to hold the bracket members 18, 20 in their closed positions against the action of spring members 50, 52. The headed studs 32 are welded to a sheet metal panel such as a boot lid 7 and clip members 34 interposed between base 16 and the heads of studs 32 secure the member 2 on to the boot lid 4, a gasket 17 being disposed between the member 2 and the boot lid 4. A plurality of such devices may be fitted to the boot lid to accommodate specialized cargoes such as skis.

Abstract: 1288837 Train control SOC ANON DES ATELIERS DE SECHERON 20 March 1970 [23 April 1969] 13713/70 Heading B7N [Also in Division G3] In an automatic train control system an information carrier is provided on the train which is driven as a function of distance travelled by the train and supplies information relating to speed V, time T for traction cut-off and change of speed and time with distance E. The data is stored in a punched tape 3 of which the first two tracks 6, 7 indicate which parameter V, T, dV/dE or dT/dE has to be changed, tracks 8-11 indicate the new value of the parameter being changed and tracks 12-16 indicate the distance at which a change has to be made. Assume a change in dV/dE, gate 18 is energized and the new value is stored in memory 22. Each time a fixed distance is travelled a pulse EU operates a pulse generator 23 to supply a number of pulsesdetermined by the value stored in memory 22, to a counter 24. The registered number of pulses are proportional to the changing value of V and this is compared with actual speed supplied from tachometer 37 in a comparator 36 to provide a control signal for brake and traction circuits 41, 42. When the tape indicates a new speed, gate 19 is energized and the value supplied from tracks 8-11 is compared in comparator 25 with the value of V stored in counter 24. The comparator supplies an output ID which is passed by gate 26 controlled by the output of gate 19 and switches memory 22 to zero. It also controls rapid pulse generator 27 to supply pulses to counter 24 to bring the value V up to that required. The tape 3 is driven by a unit 5 which is energized to move the tape one step when comparator 34 indicates that the number of distance pulses EU stored in memory 35 equals that registered in tracks 12-16. The circuit for time T control is similar to that for controlling the speed.

In the first stage a seam is produced in a protective atmosphere of an inert gas, e.g. helium, causing high penetration, and in the second stage the weld metal of the seam is remelted for only part of its depth in an atmosphere of a different inert gas, e.g. argon, causing a lower penetration, the heat of the remelting effecting a structural conversion in the unmelted part of the weld metal. The remelting may be carried out with the same welding equipment as that producing the seam. The remelting current intensity may be reduced to 70-30%. In the embodiment shown, a tube plate 1 is counterbored to a diameter D 2  which is greater than the clearance diameter for a tube 2 and extends to a depth T greater than the tube wall thickness. In order that primarily it is the tube plate which is molten, the tube is set back a distance H. The gap provided by the counterbore D 2  may have inserted therein de-oxidizing or alloying media. This welding process may be carried out in an automatic process wherein the changes of welding process, gas and current are sequentially controlled.
