Abstract: 1,082,826. Television. NIPPON HOSO KYOKAI. Sept. 25, 1964 [Oct. 19, 1963], No. 39100/64. Heading H4F. [Also in Divisions G3 and G5] Television signals are recorded on a magnetic tape 12, Fig. 3, by a rotating head assembly 14 and the tape passes into a storage chamber 15 from which it is drawn at one-fifth of the recording speed past a special rotating playback head assembly 16 and then past cue track record and playback heads 45a and 45b and the slow-speed driving mechanism 17 to take-up reel 18. The play-back head assembly 16 replays four successive transverse tracks of the tape, corresponding to a quarter of a field of a television picture, and after an interval corresponding to one field replays the next four tracks and so on. The four quarter field signals from head 16 are recorded without gaps on an auxiliary recorder and each recorded field is played back five times in sequence to give the required slow motion picture.

Abstract: 879,266. Coke-oven doors. SIMON-CARVES Ltd. Nov. 12, 1959 [Dec. 9, 1958], No. 39692/58. Class 55 (1). An automatic locking device for coke-oven doors comprises a locking bar on the door having its opposite ends protruding beyond portions of the periphery of the door the locking bar being slidable in directions perpendicular to the major plane thereof, the opposite ends each being adapted to be engaged behind a locking hook secured to, or adjacent the frame of the door and to be urged into locking engagement with the locking hooks by resilient means normally urging the locking bar away from the door, a releasing member slidable on the door in a plane substantially parallel with the vertical edges of the door and with the outer surface thereof and means of operatively associated with the releasing member to move the locking bar towards the door upon sliding movement of the releasing member vertically upwards relative thereto upon engagement with the releasing mechanism of the door lifting member of a door extractor. As shown in Figs. 1-4, a coke-oven door 2 may comprise a rectangular plate whose frame 4 encloses refractory plug 5. A locking bar 6 extending horizontally across the front of the door and engages behind hooks 7. Helical compression spring 8 may be located between rocking bar 6 and door 2 urging the latter towards frame 4. Locking bar 6 may be arranged to slide on pin 11 which is secured to the door 2 and extends perpendicularly therefrom. In addition to spring 8 a pressure plate 12 may be placed upon pin 11 and they may be secured thereupon by hollow nut 13. Plate 12 may have two opposite recessed portions 14 designed to receive the bifurcated short arms 15 of lever 16. Lever 16 may be centrally pivoted between ears of a plate 17 and a long arm 18 of lever 16 extends substantially horizontally towards door 2. The inner end of arm 18 rests on ledge 19 of a rectangular box-like slide 20 arranged to slide vertically and parallel to the planar surface of door 2 and is held in position by the vertical sides of a door-lifting hook 21 formed integrally with plate 17. Door 2 may be removed from the oven by bringing a conventional extractor mechanism into alignment and lowering its hook 24 into space 23 below flange 32 of slide 20. As hook 24 engages flange 32 slide 20 moves upwards so that its lower flange 19 upon which arm 18 of lever 16 is nesting causes the latter to rotate in a counter-clockwise direction (see Fig. 2). As a result bifurcated short arm 15 compresses the spring 8 and releases the pressure thereof on locking bar 6. Further upward movement of hook 24 causes door 2 to be lifted vertically and locking bar 6 is simultaneously lifted clear of hooks 7. In a modification (not shown) spring 8 is replaced by a corrugated flexible airchord or bellows. Specification 879,267 is referred to.

Abstract: 995,116. Actuation of switches; automatic circuit breakers. GENERAL ELECTRIC CO. Oct. 15, 1963 [Nov. 8, 1962], No. 40565/63. Heading H2B. The handle 12 of a circuit breaker 11 is operated by a movable carrier 43 driven by an electric motor 24, the motor - operating mechanism 10 being mounted as a unit in a housing 15 pivotally mounted on the circuit breaker 11 and with releasable locking means engaging the housing so that the mechanism may be pivoted out of engagement with the handle 12 to provide for manual operation thereof. An opening 49 of the carrier 43 receives the handle 12 when it is motor-operated. Pins 21 engage clips 19 on the housing 15 to releasably retain the mechanism 10 against the breaker 11. The carrier 43 has a travelling nut 50 moving along a screw shaft 39 driven by the motor 24. After the handle 12 is operated a pin 44 on the carrier 43 operates a switch 53 by its handle 56 to de-energize the motor. Further rotation of the shaft 39 then merely causes an over-running action but no further axial movement of the nut 50 (Fig. 5, not shown). A knob 24A provides for manual rotation of the shaft 39 so as to position the opening 49 of the carrier 43 clear of the handle 12 when it is desired to pivot the mechanism out of engagement therewith.

Abstract: 1,165,201. Welding by fusion. ELEKTRODENFABRIK OERLIKON BœHRLE A.G. 14 Sept., 1966 [24 Sept., 1965], No. 41155/66. Heading B3R. [Also in Division H2] In order to improve the drop transfer in a consumable or fusible electrode arc welding apparatus, the arc is fed by way of rectifiers from a transformer having a plurality of phases, the voltage amplitude in each phase being independently regulatable to produce a predetermined relationship between successive half waves such that certain half waves produce a form of preheating to form a drop and a succeeding half wave of a larger amplitude causes the transfer of the drop. A transformer 1 fed from a three phase supply RST feeds a welding arc 29, 30 by way of rectifiers 14-19, the output of which is unsmoothed so that the arc is fed with a series of voltage half waves. Each phase of the supply transformer 1 is provided with a number of tappings individually or simultaneously selectable so that the amplitudes of the successive half waves 8, 9, 10 are increased. The half wave 9 provides a so-called pre-heating function forming a drop at the welding electrode whilst the increased amplitude of the half wave 10 causes the transfer of the drop. Thus a constant drop size and a uniform drop transfer is obtained. Tapped saturable reactors 20, 21, 22 may be provided in the supply to the rectifiers to limit the welding current amplitude whilst saturable reactors 23-28 are included to provide wave shaping to give a steep front thereto thus enhancing the drop transfer. The supply transformer 1 may be formed by three single phase transformers; alternatively two single phase transformers may be used each connected to two different phases of the supply. The arc welding may be carried. out with, or without gas shielding, and, if shielded, the gas may be carbon dioxide, argon or a mixture of argon and oxygen. The consumable or fusible electrode may be of a tubular type with a filling mass therein.

The bolt may then be retreated to a temperature in the range 450‹C to the A, transformation, maintained at the temperature for fuse members and again cooled at air cooling rate or faster. The initial steel, which contains up to 0.5% C, may be hot-rolled to provide a pearlitic structure which is then normalized or annealed before cold working, or it may be hotrolled and hardened and tempered to provide a tempered martensitic structure. The cross-sectional area of the steel is reduced by from 10 to 40% and the rapid heating is made at at least 50‹C/minute. The cold working is carried out by wire-drawing or working using roller discs.
