Title: Improvements in or relating to apparatus for coating tubular fluorescent lamps
IPC: H01J9/22
Filed: 1951-05-03
Abstract: <PICT:0697998/III/1> Apparatus for coating the interior of tubular electric discharge lamp envelopes with fluorescent material suspended in a liquid, comprises a reservoir tank containing the suspension below the lower end of a tube, a vacuum operated assembly to pump the suspension to a higher level than the top of the tube, and controllable means for feeding a quantity of suspension from the higher level into the top of the tube under gravity.  The tubes are fed horizontally on a continuously moving conveyer whilst held with their axes vertical.  At the coating stage a nozzle 8 is lowered into the top of a tube 22.  The nozzle 8 comprises a cylinder arranged with a closed end downwards and an open upper end screwed to a flexible pipe 7.  This cylinder has spaced holes pierced through the curved wall near the closed end.  A second cylinder is fitted closely around the first cylinder and has holes corresponding to the holes in the first cylinder.  By turning the outer cylinder with respect to the inner cylinder the holes may be blocked or unblocked.  A reservoir tank 1 contains coating suspension, which is drawn by a vacuum operated pump 3 (see also Group XXVII) up a pipe 2, having been filtered through a gauze 5. The pump 3 feeds the suspension to a constant head reservoir 4, which has an overflow pipe 6 leading back to the tank 1.  When the nozzle 8 is in position in the top of a tube 22 the outer cylinder of the nozzle is turned to open the holes and suspension flows from the reservoir 4 through the flexible pipe 7, to run down the internal wall of the tube 22 and coats it, the excess suspension being allowed to drain back into the tank 1.  The nozzle holes are then closed and the nozzle removed, the tube passing on to a drying stage.  While the tube is being coated the nozzle moves with it along the conveyer, to return to its original position ready for coating the next tube on the conveyer.  The tubes may also be coated when their axes are inclined both to the horizontal and to the vertical, as described in Specification 697,999.

A mine roof contacting member carried by the head of a hydraulic prop 1 Fig. 2 is held against the roof at a predetermined pressure which is independent of variations in the working height during prop advance by connecting the working chamber 9 of the prop to the main pressure supply line 14 through a distributing valve 13, a pressure line 19 which also supplies the prop advancing jack 7, a throttle valve 16 and a main pressure actuated valve 11 whereby when the prop meets a hole in the roof extra pressure fluid is supplied to chamber 9 through valve 11 at a pressure which is limited by the setting of a by-pass governor valve 17 connected to a return line 20, and when the prop meets a projection on the roof, fluid from space 9 is relieved through valve 17. At the end of prop advance valve 13 is reversed thereby connecting line 19 and hence jack 7 to the return line 15 and retracting the actuator 12 of valve 11, and at the same time main pressure in line 20 opens a valve 18 and the valve 11 to gain access to prop chamber 9. The valve 13 is finally positioned so that both lines 19, 20 are unpressurized. Valve 10 is a high pressure relief valve. In a modification prop advance is effected by connecting the main pressure line 14 through valve 13 Fig. 3 to lines 23, 24. Line 23 is connected to jack chamber 22 and to the actuator of a valve 27 to close the same, and line 24 is connected to the upper chamber 29 of prop 1, the actuator of valve 11 to open the same and through a throttle 30, a line 31 and valve 11 to the prop chamber 9 the pressure in which is maintained at a value determined by the setting of by-pass valve 17 which opens into a line 26, valve 13 and the return line 15. At the end of prop advance, valve 13 is reversed, lines 23, 24 are connected to the return line 15 and lines 26, 31 are connected to the supply line 14 whereby valve 27 is opened by its spring 28, and prop chamber 9 is connected to the main pressure line 14.

Abstract: 859,996. Phase equalizing networks. POSTMASTER GENERAL. June 27, 1957 [April 5, 1956], No. 10507/56. Class 40(8). [Also in Group XL(c)] A variable group-delay equalizer comprises two parallel connected branches each having different group-delay/frequency characteristics (where # = d #/d # is the group-delay, # the phase shift between input and output and # the angular frequency) provided by all-pass equaliser networks A, B, and variable amplifier or attenuator means 5 so that the combined group-delay/ frequency characteristic taken as a vector sum of the two outputs, may be made variable between the limits set by the fixed delay equalisers A, B. Moreover, a phase shift means 8, e.g. a length of cable, is inserted in one path to equalise the phase shift in each branch at or near the mid-band frequency. The equalisers A, B in each branch also are such that approximately the same group-delay d #/d # occurs at the midband frequency in each branch. A delta pad 1 may supply the two inputs. The gain of both paths may be inversely varied by a differential gain control 9 applied to variable gain valves. The group delay equalisers 6 may each be a series pair of bridged-T networks or lattice networks. One of the parallel paths may consist only of a length of cable and the other comprise a group-delay equaliser with inverted parabola characteristic having a maximum delay at the mid-band frequency. The equalisers may be inserted at intervals in a multi-channel frequency modulation link to reduce distortion, and each branch may be variably gain controlled to compensate automatically for variations from a desired standard and linearise the over-all group-delay/frequency characteristic.
