Title: Device for fourdrinier paper machines
IPC: D21F2/00
Filed: 1959-12-08
Abstract: 863,452. Couching webs from paper-making machines. DORRIES A.G., O. Dec. 8, 1959 [Dec. 10, 1958], No. 41719/59. Class 96. The web S is couched from the wire-cloth 21 of a Fourdrinier paper-making machine to an upper felt 4 of a wet press with the aid of a pickup roll 9 mounted on a support 3 which is pivoted at 2 and which can be turned by hydraulic cylinders 28 so that a roll 12 can act as an upper couch roll, in which case the felt 4 is moved upwardly out of the pick-up position, and the web S placed by hand on to the lower felt 26 of the wet press. The roll 12 is moved pneumatically at 11 to swing about a shaft 13. The roll 9 has screw adjustment at 5. The assembly is supported from lever arms pivoted at 19 and is moved by hydraulic cylinders 17 to facilitate change of position of the rolls 9 and 12, a stop 20 being fitted. The couch roll 23 may be a suction roll and may act as a dandy roll.

Title: Lamp inspection apparatus
IPC: F21K5/12
Filed: 1958-12-24
Abstract: 876,267. Photo-electric lamp testing. SYLVANIA ELECTRIC PRODUCTS Inc. Dec. 24, 1958 [Dec. 30, 1957], No. 41775/58. Class 40(3) [Also in Group XI] Apparatus for detecting gaseous contaminants in a sealed gas-filled lamp, e.g. a photo-flash bulb, by comparative analysis of the spectral distribution of light from a gaseous discharge within the lamp, comprises a conveyer carrying holders for the lamps and conveying through an inspection chamber, means for advancing the chamber to encompass a lamp and to bring a pair of electrodes into engagement with the envelope, means for energizing the electrodes to produce a gaseous discharge in the lamp and for alternately passing the total light and the visible component of the light to a phototube. The conveyer subsequently carries the lamp to a rejection station where the variation in the discharge recorded by the phototube is used to actuate means for opening the lamp holder to release a defective lamp. In an indexing machine for inspecting lamps five at a time, the lamps 10, Fig. 3, are carried in jaws 12, 14 on a chain conveyer 20 into position for inspection whereafter a cam 108 raises a pair of bars 90 to bring chambers 84a into contact with the base of a chamber containing a phototube 69, thereby enclosing the lamp 10 and bringing a spring contact 118 connected to a high frequency source into contact with the lamp. A pair of ultra violet absorbing filters 65 are rotated around the phototube so that it receives alternately the total light from the gaseous discharge and the visible component of the light. The resulting current is fed to a comparator measuring the difference in output which is fed to a thyratron arranged to fire if the difference exceeds a predetermined amount. The thyratron actuates a coil relay 9, Fig. 6, closing contacts 9a, 9b. A cam operated timing switch 11 then closes, energizing a coil relay 13 to close contacts 13a whereby the relay 9 is kept energized. A second cam operated timing switch 15 then closes, energizing a coil relay 17 closing contacts 17a to energize a coil relay 19 and close contacts 19a and 19b. A third cam operated switch 21 then closes, energizing coil relay 23 to close contacts 23a to hold the relay 19 energized. When the lamps reach the reject station, a cam operated timing switch 25 closes, energizing coil relay 27 closing contacts 27a. If the thyratron has fired and thereby energized coil relay 9, the contacts 19b will have been closed by the above sequence of operations and the current can actuate a solenoid 29. At the rejection station, operation of the solenoid will open the lamp holding jaws 12, 14 and the lamp will fall into a bin. A separate circuit is provided for each of the lamps simultaneously under test.
