IPC: H01B13/34
Filed: 1933-11-10
Abstract: 428,292. Printing indications of length. INDIA RUBBER, GUTTA PERCHA, & TELEGRAPH WORKS CO., Ltd., Thames House, Millbank, and LEARED, H., c/o India Rubber, Gutta Percha, & Telegraph Works Co., Silvertown, both in London. Nov. 10, 1933, No. 31358. [Class 100 (ii)] [See also Groups VIII and IX] In a method of applying indications of length at spaced intervals along a length of flexible material, the material is wound into a plurality of adjacent convolutions on a support and an indication of length is subsequently applied to each of the convolutions along a line extending transversely of the adjacent convolutions. The flexible material, which may be electric cable 19, is unwound from a drum 17 and lapped round two parallel drums 11, 12, rotatably mounted in brackets 9, 10 which are adjustably supported by stands 6, 7. The upper horizontal stretches of the adjacent convolutions are supported on a table 8, through apertures in which the cable is passed to the drums 11, 12. The cable 19 passes from the drum 17, which is mounted with its centre in line with the further sides of the drums 11, 12, through guides 20, 40, 22 to the drums 11, 12 and the free end is held beneath the guide 22, while a stamp 41 is brought down upon it to mark it across a line transverse to the adjacent convolutions with length indications. The stamp 41 may be pivotally mounted and swung manually from an ink pad, which is provided on the guide 40, on to the cable, or it may be a sliding stamp automatically depressed against a spring on to the cable by the action of a cam. The marked material is rewound on a drum 23 which is preferably of such capacity as to hold all the cable required to cover completely the drums 11, 12 and table 8 with adjacent convolutions, and while this is taking place a further supply of cable is wound on to the drums 11, 12. The rewind drum 23 is driven, through a spring- controlled friction clutch which permits slippage, from the driven shaft of the drum 12, and clutches for the drives for the two drums 12, 23 may be disengaged by depressing pedals 34, 36. The bearing 15 of the spindle of the drum 11 is adjustable under the control of a screw 13 and bolt 14 to ensure the correct spacing of the drums 11, 12, and the centre of the rewind drum 23 is preferably in line with the nearer sides of the drums 11, 12.

Title: Electrical control arrangement
Inventor: HEATON-ARMSTRONG LOUIS JOHN
IPC: H03L5/02
Filed: 1962-08-17
Abstract: 1,013,546. Automatic tuning control. STANDARD TELEPHONES & CABLES Ltd. Aug. 17, 1962, No. 31657/62. Heading H3A. An electrical control arrangement in which a parameter of a variable element, e.g. a tuning capacitor or coil, is controlled by a parameter of an input signal, e.g. for tuning a transmitter tank circuit or an oscillator to the frequency of an input signal or for matching an aerial to a tank circuit, comprises means for deriving a first error signal from a course comparator, e.g. a frequency discriminator, means for deriving a second error signal from a fine comparator, e.g. a phase discriminator, and means for controlling the element in accordance with the first signal when the error exceeds a set value and with the second signal when the error is below said value. Tank circuit 4 is tuned by variable capacitors 5, 6 and coil 4 which are coupled, with variable capacitor 14 of a frequency discriminator 11, to the drive shaft of a reversible motor 45. An input signal at terminals 1, 2 different in frequency to that to which the tank circuit and discriminator are tuned produces an output signal from the discriminator which when applied to relay coil 35 operates relay 33. Via either contact 33a or 33b of the relay motor 45 is driven to adjust the tuning of the tank and discriminator circuits towards resonance with the input signal. The current from the discriminator is opposed by a current obtained via rectifier circuit 38 from the input signal and as the discriminator current drops on approach of the circuits to resonance it ceases to be effective in controlling the relay before the resonant point is reached. Control of the relay, via relay winding 34, is now exercised by phase discriminator 22 to which the input signal and a signal via capacitor 20 from the anode of the valve are applied and motor 45 is controlled to complete the tuning of the circuit.

Title: Improvements in a paper making machine
IPC: D21F1/66
Filed: 1929-10-18
Abstract: 341,543. Paper-making machines. BERRY, E. E., 815, 2nd Street, Beloit, Wisconsin, U.S.A. Oct. 18, 1929, No. 31752. [Class 96.] Fourdrinier paper-machines ; suction apparatus.- The forming wire of a paper machine is supported by a transversely ribbed belt made in longitudinal sections which run over troughs containing water under pressure to balance the pressure on the wire due to the suction which is applied through spaces between the troughs and through openings in the belt sections. The stock from a head box 13, Fig. 4, flows on an apron 14 having extended sides 15 carrying pulleys 20 for deckle straps 19, and a gate 18 adjustable horizontally and vertically by bolts &c., the apron assembly being hinged to a head box at 16 and raised when necessary to renew the wire, a table structure being removable on tracks for the same purpose. A dam 76 maintains a quiescent pond 17 from which the stock flows to a pond 17a which has the forming wire 6 at the bottom and which may have agitators close to the wire. The suction box is in independently regulated sections 23 .. 26 &c., each being connected by pipes 41 to separators 42, Fig. 2, and valves 45 to a common accumulator 46 and fan. The sections 23, 24 cause a web to be formed on the wire before it passes the gate. The troughs 49 comprise shallow boxes, preferably rectangular, extending the length of the suction box, adjacent troughs being spaced by webs, thus leaving narrow openings bounded by the trough sides and by the webs which have machined upper surfaces, which form bearing surfaces for the belt sections 35. The end walls of the troughs have aligned communicating passages open upwardly, these and the troughs being supplied with water by pipes 65 and 51 respectively, the latter being connected to standpipes 52 supplied through valves and having overflow pipes. If the water pressure is greater than is necessary to balance the downward pressure on the wire, the belt sections rise allowing water to escape at an increased rate from the troughs to the separators 42 and thus act as valves for maintaining balance, the water seeping from the troughs and end passages also acting as a lubricant for the belt sections. The belt sections are preferably of rubber &c. the base portion being reinforced with fabric. The ribs are preferably isoceles triangles in cross section and may have an outer coating or shell of hard rubber or metal. The crests of the ribs have minute corrugations thus a minimum area of the wire is closed by the supporting belt. The deckles 19 overlie the marginal portions of the wire the side-abutting members having grooves supplied with water. In a modification for existing Fourdinier paper machines the usual flat suction boxes are replaced by a suction device similar to that described above.
