Filed: 1973-04-06
Abstract: 1426628 Rolling mill installations; joining strips NIPPON KOKAN KK 6 April 1973 16479/73 Headings B3M and B3A In a continuous cold rolling mill installation in which successive strips from uncoilers 4 are welded end-to-end to form a continuous strip which is then rolled in a mill 1, a strip storage station is located between the uncoilers and mill, and the mill speed is controlled in order to maintain the quantity of strip in the station within a desired range. When a loop car 3 is positioned in the station at a location corresponding to more than a given quantity of strip in the station, the mill is run at normal speed, and the uncoiler in use is controlled so that the car remains within a definite zone in the station. When the car assumes a position corresponding to a smaller quantity than the given one, however, the mill speed is controlled in relation to the uncoiler speed. The rolling speed is reduced when the rolled strip is severed by a flying shear 8, when the strip gauge is changed, and when the ends of successive coils are welded together. If the amount of stored strip becomes too small, the uncoilers are automatically stopped, and when it becomes too large, the mill is stopped.

Title: Improvements in electric time-switches for signalling circuits
IPC: G08B5/38
Filed: 1953-06-19
Abstract: 726,871. Switching systems. VERNHES, J. M. June 19, 1953 [June 1, 1953], No. 17072/53. Class 38 (4). [Also in Group XXXVII] A time switch for controlling vehicle signalling circuits comprises a manually-operable contact lever 16 pivoted at 13 and movable into engagement with a bimetal strip 1 so as to complete a circuit through the lever 16, the strip 1, a connection 10 and the supply S. At the same time, the strip 1 is deflected by the lever 16 to close contacts 5, 8 on spring strips 4, 7 so as to close the circuit of a lamp 6. Completion of the circuit through strip 1 causes it to be heated and be further deflected so as to release the lever 16 which has been latched by the strip. The heating circuit is thus broken and the strip 1 cools down and returns to its original position, allowing contacts 5, 8 to open. The duration of closure is determined by a stop 9. Connection 10 may include a current limiting resistance R and strip 4 may be bimetallic so as to compensate for ambient temperature variations. Specification 649,884 is referred to.

Title: Tone controlled telephone answering device
Inventor: ZIMMERMANN JOSEPH JAMES
IPC: H04M1/64
Filed: 1958-05-29
Abstract: 855,410. Substation apparatus. GENERAL TELEPHONE LABORATORIES Inc. May 29, 1958, No. 17193/58. Class 40 (4). In a telephone answering and recording apparatus a record carries a tone signal during the reproduction of which a recorder is connected up for use. As shown in Fig. 1 ringing current is rectified at 8 to operate a relay 10 to connect up phonograph motor 12 over a safety switch 22 which times the apparatus out in the event of failure. Off-normal contacts 19 and 20 of the phonograph 6 provide a locking-circuit for the motor 12 and energize relay 21 which disconnects relay 10 and loops the windings 25 and 27 of transformers 26 and 28 across the line. Speech from pick-up 15 is amplified at 33, 32, and goes out to line over amplifier 34, anode voltage for the amplifiers being connected up by relay 29 when the phonograph moves off-normal. Speech signals also sporadically energize a voice-frequency relay 36 over amplifier 35 and contacts of relay 36 connect up mains to a synchronous motor 48 which through gears drives a contact operating cam 46 from a stoppin 50 towards a switch arm 47. Speech, however, does not energize motor 48 long enough at a time to drive cam 46 far, pauses in speech disconnecting relay 36 and allowing cam 46 to be returned to its stop-pin by a spring 49. At the end of the recorded message on the phonograph record the pick-up moves to a region in which a continuous tone is recorded. This tone is transmitted to the caller and also continuously energizes relay 36 so that motor 48 is driven for sufficiently long to operate switch arm 47. The switch operated by arm 47 energizes a relay 60 to disconnect the anode of amplifier 34 and cutoff tone to the caller, operates relay 59 to connect voltage to the amplifier 62 providing an input to tape or wire recorder 5, and starts the motor 51 of the recorder. Recording of a message may last as long as tone is provided by phonograph 6. When tone ceases cam 46 is reset to release relays 59 and 60 and stop motor 51. The phonograph may continue beyond this point to transmit a further message before being automatically reset when the pick-up arm is ejected. In place of the synchronous motor 48 a viscously damped relay may be used in which an armature is drawn upwards through a viscous medium to enter a solenoid and eventually increase its permeability sufficiently to attract an armature.
