Patent GB-623545-A (GB)
Abstract: 623,545. Stoves. SANFORD, H. W. Oct. 22, 1945, No. 27773. [Class 126] A cooking stove comprises a cooking top, an oven disposed beneath the cooking top and having enclosing walls at all surrounding sides and the top thereof constructed for insulating the oven, heating means beside the oven below the cooking- top and having a flue extending over the insulated top of the oven and between the oven and the cooking top for the passage of the heating gas or media to an outlet, outlet and inlet openings in different walls of the oven, conduits connecting the openings and located externally of the insulated walls of the oven and being in heat exchange relation with the heating means,. and means for positively recirculating the oven air into, through and out of the oven and through the conduits. Air escapes from the oven chamber 16 through holes 26 into the chamber 27 under suction of the motor driven fan 28, is heated in ducts 31 and 34 and returned through the damper controlled opening 35, which is closed when the door 20 is opened. Combustion products from a grate at the side of the oven circulate through the top flue 11 below the hot-plate 6 and may pass straight to the outlet 13 or be turned by the damper 15 into a flue 12. Modifications (not shown) are described in which either the combustion air or the draught may be forced by a motor driven fan, and the heating air fan may be controlled thermostatically and brought into operation only when the door is closed. In another modification Fig. 11, overlapping partitions 83 in the top flue cause the flue gases to take a sinuous course and the heated air passes from the duct 92 into a chamber 94, issues into the oven chamber at 96 in thin peripheral streams and collects in a chamber 89 before reaching the duct 92 either directly via the dampered opening 97, or via the duct 91. A further modification Fig. 14 shows a construction in which the firebox 101 is fed from the hopper 110 by a mechanical feeding device and the heated air circulates, as shown, round the firebox. A gas burner 111 may be fixed in the oven bottom chamber 107 and other burners 113 placed below the hot-plate. The solid fuel grate may be replaced by an oil burner and electric units may be used to heat the oven.

Title: Method and Apparatus for making Castings
IPC: B22D35/00
Filed: 1978-06-13
Abstract: A method and apparatus for making castings, particularly ductile iron castings. The castings are made in moulds, each having a chamber 31 in the upper portions of the mould, the chamber being connected by gating passages 30, 26 to the casting cavities. In the manufacture of ductile, or nodular, iron castings, a nodularizing agent is placed in the chamber 31. The chamber is open at the top and the molten metal flows from the chamber into the gating passages of the mould through openings 33 that are disposed above the floor of the chamber. During the pouring operation the upper surface 37 of the mould, including the open top of the chamber, is closed by a refractory sealing member 41 having a passage 82 through which the molten metal can flow. <IMAGE>

Title: Dynamo Electromagnetic Machines: Magnetic Circuits
IPC: H02K1/27
Filed: 1978-10-03
Abstract: In an electric machine of the kind described in British Patent Application No. 48794/74, iron losses are reduced by laminating the rotor backing plate (2, 4); an axial stack of insulated plates or a spiral lamination may be employed. Alternatively eddy current losses are reduced by forming the backing plates from sintered ferrite material and mounting either an array of discrete magnets or a magnetised ring therearound, or by replacing the backing plates (2, 4) and separate magnets with plates of sintered magnetic material, permanently magnetised to present alternate North and South poles therearound. Interpolar flux leakage is reduced by radially staggering the U-shaped pole pieces around the stator coil. In addition or alternatively differently shaped pole pieces may be employed, alternately, around the stator assembly (Figure 5). <IMAGE>

Title: Switching arrangements for 3- phase transformers
IPC: H02M5/253
Filed: 1979-01-17
Abstract: In a switching arrangement for connecting a star-connected, floating star-point, 3-phase transformer to a supply, the three primary windings (P1, P2, P3) are connected to the supply via respective controllable switching devices (SCR 1, SCR2 and SCR3, SCR4 and SCR5, SCR6), one (SCR3, SCR4) of which is shunted by a resistance (R1), and the switching devices are so controlled by a control means (C) that the shunted switching device closes later than the other two after any ringing occurring on closure of the other two due to switching transients has subsided. The arrangement reduces ringing due to switching transients and finds particular application to highly inductive transformers such as those used as high voltage transformers in X-ray equipment. <IMAGE>
