Abstract: 670,294. Bakers' ovens. BAKER PERKINS, Ltd. May 9, 1950 [May 30, 1949], No. 14466/49. Class 51 (ii). Additional heat is supplied to the in-feed stage of a baker's oven of the type wherein the material to be baked is carried therethrough on an endless band, by injecting into the oven at that stage hot oven atmosphere or gases which have been extracted from the oven at a stage or stages inwards of the in-feed stage. As shown applied to an oven heated by radiator conduits 1, 1a, arranged above and below a conveyer band 5 a pipe 4 is mounted transversely of the oven below the band 5 and is perforated along its side 4a which faces the direction in which the band 5 is moving. One end of this pipe is closed whilst the other is connected via the suction fan 7 with a similar transverse pipe 8 also located below the band 5 and provided with a perforated side, this side 8a, however, facing in a direction opposite to that in which the band.is moving. Oven gases are thereby transferred from a hot region of the oven to a cooler one, i.e. the in-feed stage. In lieu of single pipes 8, 4, a plurality of pipes may be provided in either or both positions, the transverse pipes in such cases being coupled to headers connected respectively to the delivery and suction of the fan 7. According to a modification gases may be extracted from several of the later oven stages, the extracted gases passing in this case to a longitudinal header coupled with the suction of the fan 7. Where a series of transverse pipes are employed each pipe is provided with a damper. The invention may be applied to an oven heated by electricity or gas.

Abstract: 815,412. Arc melting furnaces. UNTERNEHMUNGEN DER EISEN-UND STAHLINDUSTRIE A. G. FUR. May 8, 1957 [May 9, 1956], No. 14687/57. Class 39(3) In an arc melting furnace especially for scrap steel in which the furnace a is tiltable on rocking cradles b and the electrodes c mounted on supporting frame e do not take part in the tilting movement, a transformer m supplying current through cables n to clamps d on the electrodes c is mounted on the frame e and moves with the frame when the electrodes c are moved away from the furnace. When the furnace is to be filled, mechanism f raises the furnace cover g, and the supporting frame e pivoted at k has rollers h running on a track i disposed in a circular arc so as to rotate the electrodes and cover g clear of the furnace top. Busbars o supplying the transformer pass through the pivot k. The supporting frame e may be a gantry and move linearly rather than rotationally. The cables n to the electrodes are thus of constant minimum length. The furnace has no source of heat other than the arc, and the extent of movement of the frame e is insufficient to permit the introduction of the electrodes into an adjoining furnace.

Title: Improvements relating to electric motor control gear
IPC: H02P1/54
Filed: 1929-05-11
Abstract: 332,974. Asquith, Ltd., W., and Eastwood, W. May 11, 1929. Controllers, drum; motor control systems.-The control of two or more motors A, B of which only one can run at a time is effected by a master drum switch C, E, E<1>, and a single set of contactors d, g, such as would be used for one motor only. The handle h<5> of the drum controller can be moved in an H-shaped slot so that by axial movement the contacts E, E<1> select the motor to be used, and thereafter a pivotal movement of the handle one way or the other selects the direction of rotation. After such selection the contact C energizes a relay coil F to close its contact f<1> and open its contact f<2>. Closure of contact f<1> causes enrgization of contactor coil D with resultant closing of main contacts d and opening of contact f. The relay, however, does not close its contacts f<2> immediately, because the rotor current through coil f<3> maintains energization of the relay until the rotor current has subsided, whereupon contacts f<2> reclose to energize contactor coil G and close the rotor resistance shorting contacts g, g<1>. In a modification the master drum also selects the speed of running of one of the motors which is, in this case, provided with a double wound stator. A locking lever j<1> and a switch in the control circuits can be provided so that the use of one of the motors can be prevented when desired.

[Class 72] [Also in Group XXII] Piston and other rings are made from precast lengths of drawn wire by heating each length and separately bending them squarely without helix around a grooved mandrel in which the three sides of the groove determine the form of three faces of the ring, then hardening on the mandrel by quenching whilst simultaneously forming the outer peripheral face of the ring by an external die, and then discharging the hardened and formed ring from the mandrel. The lengths of wire may be provided with scarped or stepped ends. A wire length 1 after heating may be bent by rollers 7 on spring-pressed pivoted arms 4 round the part 9 of a mandrel consisting of the integral parts 9, 10 carried by the shaft 11 and the part 8 pressed against the part 9 by a spring 8A. After bending the shaft 11 is pressed downwards to push the ring through a sleeve 12, which is slightly tapered at its upper end and projects into a quenching tank 13. The ring is thus held tightly on all four surfaces during quenching. In its lowest position the ring slightly springs out clear of the lower edge of the sleeve. After quenching the shaft 11 is raised and the ring discharged laterally so as to fall into the water in the container 13. The ring may be finished by lapping. Specifications 535,496 and 550,817, [both in Group XXII], are referred to.
