Title: Improvements relating to apparatus for producing photochemical radiations
IPC: B01J19/12
Filed: 1929-04-10
Abstract: 309,497. Spindler, H. April 11, 1928, [Convention date]. Arc lamps; low-pressure metallic-vapour apparatus.-A mercury-vapour lamp for producing ultra-violet and other photo-chemical radiations consists of tubes 5, open at the top and containing mercury, in which are immersed quartz tubes 20 joined together by a chamber 21 for the arc the tubes 5 being surrounded by a cooling liquid at high pressure and in contact with the mercury so that the pressure inside and outside the chamber 21 is equalized. The container consists of a cylinder 1 closed at the lower end by a cover 4 and at the top by a chamber 2 having a cover 3 with a window 18 provided with a lens 19 of quartz or fluorspar. Cooling liquid such as water or paraffin oil passes through the container and through a coil 9 immersed in a cooling liquid such as water in a jacket 12; a pressure gauge 16 and a cock 17 are connected with the chamber 2. Cooling liquid may also pass through a coil 22. The pipes 20 extend to near the bottom of the tubes 5 and are so long that the arc in the chamber 21 may be started in a barometric vacuum before the pressure is applied to the chamber 2. When this pressure is applied, a concentrated arc at high temperatures is produced. The lamp may be used to produce intra-molecular transformations, polymerizations and condensations, photolysis, hydrolysis, oxidations and radioactive transformations. The synthesis of formaldehyde from a mixture of carbon monoxide and hydrogen is described. The Specification as open to inspection under Sect. 91 (3) (a) comprises also means for admitting to the chamber 2 the gases or liquids to be subjected to the rays. This subject-matter does not appear in the Specification as accepted.

Title: Method and apparatus for the testing of the presence of threads in textile machines
IPC: B65H63/02
Filed: 1975-03-18
Abstract: 1478098 Counting yarns SCHWEITER ENG WORKS Ltd 18 March 1975 [18 March 1974] 11240/75 Heading D1F A method of testing whether, in the operation of textile machinery, a thread to be picked up for subsequent handling has been picked up properly or not or if multiple threads have been picked up, comprises counting the number of threads being picked up. Upon sensing of a broken yarn, or upon reaching the end of the yarn at a particular spooling station of an automatic spooling machine of the multi-spindle type that station may be brought into cooperation with a defect sensing and clearing mechanism 2, e.g. by locating the stations or the meshanism 2 on a rotating turret. Each station includes a rotating grooved roller 1' which drives a spinlle carrying a core 3 so that yarn 4 is wound thereon. The mechanism 2 comprises a suction nozzle 6 connected to a suction pump (not shown) and which is supported by a movable parallelogram linkage 8. Proper pick-up of the yarn 9 by the nozzle 6 is monitored by a sensing and counting device 10 operating on a counting principle and which is mounted on an arm 11 to move transversely to the direction of the thread 9 passing into the nozzle 6. The path of the device 10 includes the region not only in which the thread 9 can be expected but in which multiple threads 9' would be located. A vertically movable bail 13 directs the threads 9, 9' into a single plane. In one embodiment, the device 10 has a test gap 12 having, at opposite portions thereof, an optical test gate comprising a light emitting diode 20 and a photo transistor 21. A pulse in the test gate caused by a thread applies a signal to an amplifier whose output is applied to a Schmitt trigger to form square wave pulses which are applied to a counter. In operation, with the device 10 retracted and the bail 13 raised, the nozzle 6 is moved towards the yarn package and after picking up the threads 9, 9' is retracted. Simultaneously with the retracting, the bail 13 is dropped. The arm 11 is moved to the right and the threads 9' 9 each cause a pulse as they pass into the gap 12. Initiation of movement of the arm 11 energizes the counter and the counting thereby of the two threads applies a signal to an amplifier to actuate a cutter 26 in the gap 12 to cut both threads 9, 9'. The arm 11 is returned and the counter re-set. The control signal for the cutter 26 can also be used to re-initiate a thread pick-up operation so that, if the first operation was unsuccessful in picking up a single yarn, the desired single thread 9 may well be picked in the second operation. If the number of repeat operations exceeds a predetermined value, e.g. three, an additional counter may stop further search or pick-up operations and provide an alarm signal. In another embodiment, the optical gate 20, 21 may be replaced by a capacitative system comprises a pair of plates located one on each side of the gap 12. In a further embodiment, the mechanism 2 can be applied to the supply spool rather than the wind-up spool

[Class 80 (iv).] Machines such as reciprocating engines are mounted on a support by flexible means placed near the intersection of the varying natural oscillation axes of the engine which result from the action of the periodical internal rectilinear forces, the periodical internal torques, and external spring supporting means. A machine 4, Fig. 2, is supported by a flexible band 6 located according to the foregoing principle and helical springs 5. In place of the band 6 there may be a composite band in two sections at right angles. An engine may be supported on the frame of a vehicle by a band 6, Fig. 9, springs 13 laterally spaced, and a central spring 12 at the other end. According to the Specification as open to inspection under Sect. 91, excessive movements are prevented by a resilient member, comprising spring leaves 15 and a soft end covering 18, Fig. 12 (Cancelled), which projects into a cavity in a block 20. In a modified arrangement of engine supports, two horizontal strips take the place of the band 6, the springs 13 are placed at the side of the engine and the spring 12 is omitted. In place of the device shown in Fig. 12 (Cancelled), a dashpot of the construction shown in Fig. 17 (Cancelled) may be used. A slack piston 32 loose on a rod 33 is constrained by springs 35 abutting on stops 34. The springs allow normal vibrations, but excessive movements tend to cause the piston to move and are therefore damped. This subject-matter does not appear in the Specification as accepted.

Abstract: 551,833. Actuating signals on trains. HALSTEAD, W. S. Sept. 9, 1941, No. 11538. [Class 105] [Also in Groups XXXVIII and XL] A phonographic reproducer, e.g. a telegraphone, is associated with a wireless transmitter for giving messages automatically to road or rail traffic approaching a signal. As shown, when power is connected to the circuit 46 for illuminating the green signal 41, a timing device 33 is set into action and after an interval operates relay 32 to start the telegraphone 30 and connect its output to the radio transmitter 10. Similar arrangements may be made in association with the circuit 42 for the red signal. When circuit 76 for showing green to the other (cross) traffic lane is energized, a timing device 37 similarly energizes 36 which starts a telegraphone 34 and connects it to a loudspeaker on the signal standard. The carrier currents may be further modulated by a tone generator 45, the frequency of which depends on the condition of relays 38, 44 so that audible indication of the condition of the signals and a warning that they are going to change may be received by a radio receiver on a vehicle. These tone signals may control characteristic lamps on the vehicle. Means may be provided for recording any emergency message on the telegraphone on the spot. To localize the radio signal, it is preferably guided by buried cables. The carrier frequency in use is indicated on the signal standard. The telegraphone &c. may be mounted with the transmitter or at a central point.
