Abstract: 384,744. Rolling tubes. WITKOWITZER BERGBAU UND EISENHUTTENGEWERKSCHAFT, and TSCHULENK, L., 79A, Grenzstreet, both in Witkowitz, Czecho- Slovakia. Oct. 13, 1931, No. 28394. [Class 83 (iv).] Mandrel carriages and feeds.-In a pilger mill the four roll segments 2 are oscillated by hydraulic cylinders 10 in a vertical plane at right angles to the tube axis the cylinders 10 being connected in pairs by the rods 12 to balance the thrust. Short connecting-rods 4 couple the plungers 5 to the roll segments 2. The cylinders 10 may be arranged double acting but as shown the return stroke is effected bv plungers 6, Fig. 3, moving the pull rods 8. The roll segments 2 are also coupled by horizontal links 13 to a mandrel carriage 14 on wheels which is thereby oscillated longitudinally. To begin operation the mandrel 15 on its rod 16 is withdrawn, Fig. 2, by the piston in the hydraulic cylinder 17, the rod 16 being coupled thereto through a motor-operated locking slide 18 and middle section 35. The hollow billet, being placed in the carriage 14 the mandrel is advanced to position and working continues. The mandrel, billet and carriage oscillate with the roll segments but the billet is urged forward (to the left) by a push ring 30 backed through a spring 31 by a crosshead 29 moved forward step by step by threaded spindles 27 rotated from an electromotor 22, Fig. 7. As the billet is rolled out it elongates to the left along the mandrel. The work is also rotated through say 45‹ from the spindles 27 by pinions 32 to the gear 33, the step-by-step feed and rotation being obtained by switching on the electric motor 22 automatically after each working stroke of the roll segments 2. When completed the mandrel and tube are withdrawn clear of the rolls by the hydraulic piston 17, until the tube abuts against the bush 30 when the piston 17 strips the mandrel from the tube which can be lifted away by a crane. The piston in the hydraulic cylinder 17 does not partake of the mandrel oscillation as a lostmotion bore 40 is provided in the back end of the mandrel rod.

Abstract: 345,610. Television. TELEHOR AKT.-GES., 14, Hindersinstrasse, Berlin. Sept. 20, 1929, No. 28548. Convention date, April 5. [Class 40 (iii).] In a television system the receiving scanning disc is driven in synchronism with the transmitting disc by a tuned relay, controlled by synchronization impulses stronger than the picture currents and inserted in the driving circuit of the motor at the receiver. The incoming signals are fed from a receiver 19 to a glow lamp 20 and the coil 21 of a tuning fork 22 which is energized to interrupt at the frequency of the synchronization impulses the driving circuit of a phonic wheel 23 rotating the Nipkow disc 24, the picture currents being ineffective to influence the tuning fork. The Specification as open to inspection under Sect. 91 (3) (a) describes arrangements by which the synchronization impulses are generated purely electrically from a battery by commutator brushes and segments on the shaft of the transmitter scanning disc. The synchronizing impulses are superimposed on the photo-electric currents or, in a modified arrangement, the picture currents are interrupted during the production and transmission of the synchronizing impulses. This subject-matter does not appear in the Specification as accepted.

IPC: G01S15/10
Filed: 1924-12-02
Abstract: 227,801. Langevin, P. Jan. 14, 1924, [Convention date]. Thermionic relays.-The output current of a thermionic valve system is interrupted except during the time-interval between the emission of a supersonic acoustic impulse and the arrival of the echo. The sound detector is so connected that on the receipt of an echo an oscillatory E.M.F. is applied to the grid of a valve P, Fig. 1. The ammeters A, which are calibrated to give the depth directly, are connected in the output circuit of the valve L<2>, an amplifier L<1> being interposed. Current in the ammeters A is normally interrupted by a negative charge on the grid G<2>, but at the instant when an acoustic impulse is being emitted the key K is momentarily closed so as to release the charge on this grid and start the current in the ammeters, which continues to flow after the key K has been reopened until on the receipt of an echo the valve P acts to re-establish a blocking charge on the grid G<2>. The arrangement shown in Fig. 3, is designed to economise the number of batteries required. The keys K, K<1> are simultaneously and momentarily closed at the instant when the acoustic impulse is emitted, a positive charge being thus imparted to the plate P while the negative charge on the grid G<2> is discharged. Current therefore flows in the instruments A until the application by the echo of an oscillating E.M.F. to the valve P occasions the discharge of the plate p and the accumulation of a blocking charge on the grid G<2>. The above cycle of operations being repeated at a uniform rate, the reading of the instruments. A will depend on the fraction of the cycle during which current flows through them.

Filed: 1939-10-28
Abstract: 534,714. Cutting by fusion. HANCOCK, L. J. Oct. 28. 1939, No. 28886. [Class 83 (iv)] The burner of a flame cutting machine is automatically kept at a substantially constant height above the work by a reversible electric motor, which raises or lowers the burner through gearing and which is controlled by two electric relays and one or more runners which contact with the surface of the work and control the energization of the relays. The burner 3 which is slidable in the holder 2 or attached to a slide at the end of the arm 1 of a profile cutting machine has secured thereto a carrier 7 connected by a push-pull rod 5a to a rack 5, which may be reciprocated either by a hand wheel or by reducing gear from a reversible electric motor 22. To the carrier are secured a pair of tubes 8 connected by a U-shaped yoke 9. Through the tubes pass a pair of rods 10 which are rounded or provided with ball ends 11 to engage the work and to which may be secured a ring 19 having one or more additional legs 20 to avoid failing of the control device by the runner passing over the edge of the plate. The upper ends of the rods are connected by a yoke 12 and an extension 14 is provided on which is adjustably mounted a non-conducting screwed sleeve 15 having a conducting inset 16 forming part of a switch and co-operating with blade springs 18 in a switch box 17 secured to the burner. The inset 16 contacts with the centre spring and either of the outside springs when the runners pass over uneven or inclined surfaces of the work and so the motor is rotated in one or the other direction. When the desired position of the burner is reached the switch is in neutral position and the motor stops. The switch is in a battery circuit energizing one or the other of two relays so as to energize the armature of the motor in one or the other direction and also to energize the field. If the rods 10 pass beyond the edge of the work they fall and the inset 16 falls below the centre spring and the motor stops. In a modification for cutting round bars the carrier is provided at each side with cross bars 32. 34 with reduced ends 33 serving as pivots on one or the other of which are applied by notches 38 the levers 36. These levers, which have rounded ends 40, are connected together by a cross bar 37 and are provided with projections 39 engaging projecting feet 35 on the rods 10 so as to operate the switch. When the position of the levers 36 becomes such that the ends 40 can fall away from the work surface the runners 11 on the ends of the rods maintain the control. The rack and pinion may be replaced by screw and nut mechanism.
