Filed: 1971-07-01
Abstract: 1285669 Packaging machines; pneumatic and endless conveyers INTECH CORP 1 July 1971 [24 Aug 1970] 30806/71 Headings B8A and B8C In a method and apparatus for packaging hosiery articles, each article 22 is vacuum formed to the general configuration of a packaging carton C which receives the article. The articles leave shrinking and dyeing apparatus 10 and are conveyed separately to either of a pair of semi-boarding machines 12 along a pneumatic conveyer system 20. Vacuum assist devices 24 load the articles 22 on to frames 26 which are then expanded and moved on endless chain 30 past an inspection screen and then to inlet 34 of a dumb-bell section pneumatic tube 36 of conveyer 14. Inlet 34 leads first to a selector valve assembly in which element 178 is movable, by a fluid motor controlled by the operator, to any of three positions, (a) via pipe 378 to a packaging station 18, (b) via pipe 40 to a stacking station 16, or (c) via pipe 46 to a reject bag 44. At each stacking station, a tray 208 with central divider 210 is placed on platform 218 adjacent outlet 256 of pipe 240 and is lowered until filled with stacked articles 22. Switches 236, 238 limit the shift of platform 218 and control the supply of trays. Switch 256 actuates a counter determining the number of articles and controlling a pivoting action of pipe 240 to assist discharge of the articles. Collapsed cartons are removed from magazine J1 by suction gripper J46 and are erected and moved along rails J47, J55 by lugs J24 on endless chains J22, J23 to underlie opening 312 in a plate 310 of carton filling mechanism. Vacuum-forming chamber assembly 328 extends between plate 310 and another plate 320 apertured at 324, 326, and is movable from the position of Fig. 15, in which an article 22 is received, to the broken-line position where the formed article is pushed by head 368 down into a carton C. Vacuum applied from tube 316 draws an article from table 380 along conduit 382 to assembly 328 for shaping.

Title: Improvements in and relating to carbureting devices for internal combustion engines
IPC: F02M21/00
Filed: 1919-12-15
Abstract: 160,256. Hodges, E. G. Dec. 15, 1919. Spray carburettors.- A butterfly-valve controlled by an external governor is employed for supplying auxiliary air to the engine side of a butterfly mixture valve. The governor may be arranged simultaneously to control butterfly - valves for main and auxiliary air, and also for mixture if desired. Further, an additional governor-controlled auxiliary - air valve may be used to limit the maximum speed. In the form shown in Fig. 1, the main air passage 3, controlled by a spaced butterfly - valve 14, leads through a Venturi tube 6 to a mixing-chamber, the outlet from which is controlled by a butterfly throttle valve 12. The auxiliary air-passage controlled by a butterfly-valve 15 leads to a space 11 surrounding the mixing-chamber, the air being supplied in an annular stream on the engine side of the throttle valve 12. The air valves 14, 15 are connected together by a link 18 and to a governor 21 by a link 19, the arrangement being such that the valve 14 moves more quickly than the valve 15. The arm 12<1> of the throttle valve mav be connected either to a rod 13 for hand actuation, or, as shown in chain lines, to the, governor, which then tends to close the throttle and open the airvalves when the speed rises and vice versa. The pipe 8 supplying the fuel nozzle 5 may be coiled within the exhaust pipe 9. In a modification, Fig. 5, an additional auxiliary-air valve 38 is opened by a governor 39 to thin the mixture when nearing the maximum speed. In a further modification, the auxiliary-air valve and mixture valve only are connected to the governor so that, as one is opened, the other is closed.

Title: A synchronizing arrangement for a sawtooth wave generator
IPC: H04N5/12
Filed: 1950-12-29
Abstract: 687,893. Automatic frequency control systems. RADIO CORPORATION OF AMERICA. Dec. 29, 1950 [Dec. 30, 1949], No. 31596/50. Class 38 (iv). [Also in Group XL (b)] A wave generator, particularly the saw-tooth scamiing generator of a television receiver, is synchronized with a pulse train by distorting the waveform so that it exhibits a flattened portion, superposing the pulses on the distorted waveform, and deriving from the composite wave a voltage for controlling the frequency of the wave generator. In Fig. 1, a sawtooth voltage is generated on the condenser 22 by charging it from a source B + through a resistor 21 and discharging it periodically through a valve 26 connected as a blocking oscillator and comprising coupled grid and plate coils 32, 33 and a grid condenser 38. The sawtooth voltage is applied to a valve 12 which feeds scanning- coils 16 through a transformer 14. The sawtooth wave is partially integrated by a resistor 64 and variable condenser 66, and their junction is connected to earth through condensers 71, 73 and low resistance 76. The synchronizing pulses 44 are fed through a cathode follower valve 78 and condenser 73 to the grid of a mixing valve 59 and are there superposed on the wave fed from the condenser 22 through the network comprising resistor 64 and condensers 66, 71. The effect of the network is to round off the base 69, Fig. 3A, of the wave and to flatten the portion 82 that precedes the steep fall 108. The valve 59 is back-biased so that it only passes current when its grid voltage is above the upper limit of the waveform 46. If the generator is running slow the pulses 44 ride on the wave 46 as shown in Fig. 3A, and give rise to plate-current pulses shown in Fig. 3B. These pulses are smoothed by a network 98, 99, 101, and the smoothed positive voltage across the cathode resistor 89 is applied to the grid of the blocking oscillator to adjust the moment of firing and thus to control the frequency of the wave 46. Owing to the flattened crest 82 of the wave 46, a larger proportion of the pulses contribute to the control voltage. Two grid leaks 86, 87 are connected in series between the grid of the valve 59 and the junction of the cathode resistors 88, 89; and the junction of the leaks is connected to the cathode by a condenser 91. A resonant circuit 109, 111 interposed between the condenser 22 and the junction of coils 32, 33 is tuned to the wave frequency.
