Abstract: 1,000,492. Electric calculating apparatus. ELECTRA TOTALISATORS PTY. Ltd. Sept. 24, 1963, No. 37525/63. Headings G4A and G4D. [Also in Division H2] An electromagnetic decimal accumulator comprises stepping units (one in each decimal denomination) and in addition at least one twoposition indicator representing decimal 5, input signals representing five units operating the latter, whereas inputs of lower significance operate the stepping device in that denomination. As shown, the accumulator comprises a number of double-acting relays with both instantaneous and toggle-type contacts (see Division H2) 2BH &c., and 5C &c., and for each decimal denomination a device U1, T1, H1 ... which when energized operates through pawl-and-ratchet a numeral wheel (see Division H2). In the units and tens denominations double-acting relays 5C, 50C control flags registering 5 and 50, and these are switched by input signals representing 5 and 50 units respectively, applied at input terminals 51MP, 501MP, inputs at other " MP " terminals (e.g. 21MP) operating the numerical wheels. The accumulator is described as for registering bets of ranging amounts (2, 5, 10, 50, units) and includes means for producing " cancelling " signals 2BR &c. to transmit to remote equipment to indicate that the bet has been registered, and electrical takeoff by contacts 1BT &c. on coding wheels on the numeral wheel shafts. The numeral wheels in the lower orders are ten-position, and since the lowest bet entered is 2 units, the wheel of Ul steps 0, 2, 4, 1, (with a transfer pulse from contacts C via relay 2/5H to 5C), 3, 0. Switching of 5C produces a pulse on line X to operate transfer relay 5/10H and thus apply a pulse over line 48 to the tens indicator T. Specifications 986,124 and 980,040 are referred to.

Title: Improvements in or relating to coating hollow bodies
IPC: B23K20/02
Filed: 1962-10-05
Abstract: 966,435. Making composite tubes; drawing tubes; welding by pressure. STAHL-UND ROHRENWERK REISHOLZ G.m.b.H. Oct. 5, 1962 [Oct. 5, 1961], No. 37744/62. Headings B3A, B3P and B3R. A method of making seamless ferrous hollow bodies coated with ferritic or austenitic corrosion resistant steel or other corrosion resistant metal, particularly tubes, by hot pressing of a double tube comprising a main tube and a lining tube over a mandrel on a drawing or thrust frame, characterized in that for the reduction and cleaning of the tube surfaces to be joined a gaseous reducing medium is passed through a ring-shaped gap between the main tube and the coating tube at the treatment temperature before the hot pressing. One end of an austenitic lining tube 3 supported by and welded at each end to an unalloyed steel strengthening tube 4 is positioned in and welded to an annular groove 2 of a conically shaped weld plate 1. A ferrtic outer tube 5 having an internal diameter greater than the outside diameter of the tube 3 is slid over the tubes and welded to the plate 1. The air gap so produced is closed at the open end by a heat deformable ring 7 welded to the tubes 3, 5. The assembly is heated to drawing temperature and a reducing medium, e.g. hydrogen is passed through a number of vent holes 8 in the ring into the space and out through vent holes 9 in the plate 1 to remove surface impurities. The assembly is subsequently positioned on a drawing mandrel and drawn through a ring to press and weld the tubes together. After heat treatment the ends are sawn off and the strengthening tube removed. To facilitate separation of the tubes 3 and 4 the contact faces are coated with an oxide coating. Wire having a thickness equal to the width of the air gap may be spirally wound about the austenitic tube 3 to facilitate positioning of the outer tube 5. External coatings can be similarly produced by pressing an austenitic tube strengthened by an outer tube on to an inner tube.

Title: A fluid pressure-regulating valve
IPC: F04B53/10
Filed: 1969-08-04
Abstract: 1282935 Valves DANFOSS A/S 4 Aug 1969 [3 Aug 1968] 38940/69 Heading F2V [Also in Division G3] A fuel flow regulator has separate pistons 32, 33 biased by spring 36 to abut sealingly via O- ring 62 and prevent flow from inlet 24 to passages 45-47 in an auxiliary piston 34 biased by spring 64 to abut sealing washer 66 on piston 33 and adapted to close outlet 7. Upon application of pressure to inlet 24, piston 32 shifts rightwards to relieve piston 33 of the load of spring 36 and to uncover passages 45. Fuel then flows via 45-47 to chamber 48 and piston 33 moves rightwards to a position in which the pressure drop across orifice 51, 52 is balanced by spring 56. Piston 33 then acts to maintain a constant flow rate to outlet 7, which has been opened by rightward movement of piston 34 accompanying piston 33, by variably opening one or both of return ports 26, 28 to sump and pump inlet respectively and by adjusting the orifice 51, 52. Fuel can leak to chamber 53 to provide a dashpot for pistons 33, 34, although, upon loss of inlet pressure, fuel in chamber 53 allows spring 36 to drive piston 34 leftwards slightly ahead of piston 33 to close outlet 7, pressure built up in chamber 48 by piston 34 causing piston 33 to open ports 26, 28 temporarily. Pressure in chamber 53 is limited by relief disc 42. Additional sealing is obtained by means of 0-ring 68, which is retained by split tube 71. In a modification (Fig. 3, not shown), piston (75, 77) controls the return and outlet ports and piston (74, 76) controls flow between the inlet and outlet chambers via external line (80) having restriction (81). In Fig. 4, not shown, both pistons (90, 91) control flow between the inlet and outlet chambers but piston (91), which is equivalent to 33, above, has no control over the outlet.
