Title: Split lebel conveyor and collecting means for controlled cooled steel rod
IPC: C21D9/573
Filed: 1971-06-28
Abstract: 1323027 Coiling and winding MORGAN CONSTRUCTION CO 28 June 1971 [3 Aug 1970] 30133/71 Heading B3E Conveyer and collecting apparatus for hot rolled steel rod 6 comprises conveyers 1, 3 for receiving rod in overlapping non-concentric rings 2 formed by a coiler 7, means for stopping the movements of rod along the conveyer 3, a collector 5 for forming the rod into ring bundles 13 and severing means, Fig. 5a, operative in conjunction with the stopping means and including a positioning arm 17 which moves a hanging portion of the rod into engagement with a shear 20. The rod is air cooled on the conveyer 1 by blowers 9 after which the rod drops through a tub 10 on to the second conveyer 3, the speed of which is controlled by a motor and drive mechanism 26. Tractor chains 12 receive the rings from the conveyer 3 and feed them uniformly into the collector 5 where they drop around a guide post to form a bundle 15 which is carried away on a third conveyer 14. When the desired bundle size is attained the conveyer 3 and tractor chains 12 are halted and the hanging portion 21, Fig. 5a, of the rod is cut by the shear 20 in combination with the movement of the plate 18 and pivoted positioning arm 17. After the severing operation the conveyer is restarted to run at a higher speed than the first conveyer until the excess rings in the tub 10 are removed. These rings have built up because the conveyer 3 has been running continuously so as not to interrupt the cooling treatment and so affect the physical properties of the rod.

Title: Method and apparatus for reducing interference between pulses in electrical signal transmission systems
IPC: H04L25/03
Filed: 1954-10-20
Abstract: 757,962. Pulse code modulation circuits. WESTERN ELECTRIC CO., Inc. Oct. 20, 1954 [Oct. 21, 1953], No. 30212/54. Class 40 (5). Interference between fixed amplitude pulses, which during. transmission have been distorted to produce a tail portion, is reduced by generating new pulses from samples taken during the time intervals allotted to the pulses and obtaining from each a succession of subsidiary pulses whose amplitudes are related to the amplitude of the tail portion of the distorted pulse in the time intervals of succeeding pulses, the subsidiary pulses being used to derive a correcting wave for subtractive application to the distorted pulse. In the embodiment described, each pulse A, Fig. 2, from a transmitter 1, Fig. 1, which may be of positive or negative polarity in a binary code system, is distorted by the channel 2 into a form such as B. The pulses are sampled in circuit 4 under the control of a timing wave source 7, the samples being passed to an amplitude identifier 5 which passes a positive or negative output pulse to a new' pulse generator 6 also controlled from source 7 and feeding the utilization circuit 16 through a delay network 19. The output of generator 6 is also fed to a delay line 9 the tappings 11 of which give correcting pulses whose amplitude and polarity C, Fig. 2, are determined by attenuators 13 and switches 12 respectively, and the correcting wave D is fed through an inverting amplifier 15 to the input of the sampler 4. Blank intervals may be periodically inserted into the pulse train at the transmitter to afford synchronizing signals and to enable the receiver to clear itself of any error stored in the delay line 9. Alternatively these gaps may be inserted at the receiver by counting the cycles of the timing wave from generator 7 and after 10,000 cycles, for example, tripping a singletrip multivibrator 18 to open switches 20, 20<SP>1</SP> for a suitable interval. Switch 20 disconnects the sampler 4 from the incoming pulse channel and switch 20<SP>1</SP> inhibits the new pulse generator 6. If, due to an error, an excessive pulse amplitude arises at the input to the sampler 4 a voltmeter 21 responds to actuate a threshold device 22 to open a switch 23 at the input of the utilization circuit. In order to increase the signal/noise ratio, pulses from the generator 6 are inverted in circuit 26, delayed in circuit 27 and added in conductor 25 to received pulses delayed in circuit 24, the delays being such that each generated pulse coincides with the next received pulse. The conductor 25 thus carries pulses representing a noise component which are inverted in circuit 28 and added to the output of sampler 4 substantially to cancel the noise component of the sample pulses. It is stated that the cut-off frequency of the lowpass filter 3 at the input of the receiver may be reduced to one-third of the normal value.

In a combined thermal regenerator and tubular heat exchanger having a group of wound tubes permitting the passage of a fluid therethrough in heat exchange with fluids passed externally of said tubes and through a regenerative section, the regenerative section has a filling which is composed of thin metal strips which are assembled together in stacks and positioned between consecutive tube turns of the wound tubes, the metal strips being maintained in spaced relationship within the stacks by spacer means constituted by partly punched-out tabs formed in the metal strips. In the form shown an axial core 5 is surrounded by wound tubes 6, 7, each layer of tubes being wound in an opposite direction to the underlying one. Metal strips 8 comprising the regenerator filling are placed in position between the tube turns as stacks of arcuate form, Fig. 2, the individual strips within each stack being separated from each other by partly punchedout tabs which also serve as a suitable means for connecting the strips together by brazing, gluing &c. Individual stacks are separated from each other by springs 9 and a continuous strip 10 surrounds the individual stacks and secures them in position, the strip 10 itself being fixed at its ends to the subjacent stack and also nailed at intervals to the stacks underlying it. The completed regenerator-heat exchanger comprises a central zone 16 formed by the assembly of the wound tubes and regenerative filling detailed above. Gases passing in direct contact with the regenerative filling pass through pipes 17, 18 and a separate gas passing through the wound tubes enters through a pipe 19 into a distributer 21, flows through the tubes and leaves via a collector 22 and a pipe 20. The axial core is connected to an outer casing by beams 25.
