Title: Filter apparatus
IPC: B01D29/09
Filed: 1964-12-04
Abstract: 1,093,174. Filter. AJEM LABORATORIES Inc. Dec. 4, 1964 [Dec. 6, 1963], No. 49529/64. Heading B1D. Filter apparatus comprises at least one suction box disposed within a tank for containing liquid to be filtered, the or each suction box being connectable to a source of suction and having a pervious filter face through which liquid enters the box, an endless pervious conveyor belt disposed about the suction box or boxes so as to be movable across the filter face or faces thereof, said conveyor belt supporting a strip of filter medium on its outside with respect to the suction box or boxes, and edgesealing means pressing on the outside of the filter medium at opposite edges thereof so as to press said edges against the belt which is thereby pressed against the or each suction box at opposite lateral edges of its filter face. In Figs. 1 and 3, the filter apparatus comprises suction boxes 30, 32 each having a pervious filter face, an endless pervious conveyor belt 19 which is moved at intervals on rails 23 across the pervious face while supporting a strip of filter medium 12, and edge sealing means comprising belts 22 which bear down on the filter medium 12. The boxes are connected via duct 36, 38 and a three way valve 34 (Fig. 4) to suction pump 32. Rails 23 may be made of neoprene, polytetrafluoroethylene or nylon. Water jet 41 stirs up the sedimented solid so that it is removed on the filter medium. In operation, suction is first applied via line 38 to upper box 30 up to a predetermined pressure differential across the filter element caused by clogging, which differential operates switch 48 (Fig. 4) to alter valve 34 to transfer the suction to line 36 and lower box 32 and to energize time delay switch 54. Switch 54 causes switch 48 to cut off suction from box 32, and then allows water to filter into the box to reduce the vacuum before energizing motor 27 to rotate roller 28, and pull-rolls 50 and hence move conveyor belt 19 and the filter medium 12 on by a distance equal to the length of the pervious filter face of the upper box. The time delay switch 54 then activates switch 48 to allow suction via valve 34 and line 38 to upper box 30.

Title: Ink fountain for printing,duplicating or like machines
IPC: B41F31/04
Filed: 1965-11-22
Abstract: 1,111,182 Printing machines: inking apparatus. ADDRESSOGRAPH MULTIGRAPH CORPORATION. 22 Nov., 1965 [28 Jan., 1965] No. 49546/65. Heading B6C. Ink from a slitted elongated flexible envelope is fed to the fountain roller of a printing press by squeezing the envelope, such squeezing being effected so as to maintain contact of the body of ink in the envelope with the roller as the ink is being withdrawn by roller rotation. In the first embodiment, Fig. 4, an elongated envelope P is placed after removing the slit tag F1 between an adjustable duct blade 15 and an upper pivotally mounted pressure plate 17. This plate is depressed a predetermined amount every time the messenger roller contacts the fountain roller 13, the motion from the moving messenger roller being transmitted to the plate through worm gearing 103, 101, screw gearing 95, 91 and a cam 19. Such motion winds a clock spring 99 such that on release of the drive the parts 17, 19, 91 and 95 return to their initial position to allow removal of the empty envelope P prior to replacement. The plate 17 may also be actuated manually, a knurled knob 105 being provided for this purpose. A clutch arrangement ensures that when the plate 17 has expelled the entire ink contents of the envelope P further rotational drive from the continuing messenger roller movement is allowed to idly slip. To charge the space between the blade 15 and the plate 17 with an envelope a handle 25, Fig. 2, is actuated to raise the upper section U of the fountain from the lower section L. On the depression of the handle 25 the upper section, which is spring biased downwardly, descends, the rear edge of the envelope P being gripped between a serrated edge 126 of the upper member and the blade 15. A dial and pointed arrangement is provided at one end of the worm shaft 109 to indicate the extent of the contents of the envelope. The entire fountain U, L is mounted as a unit about the fountain roller and is readily removable therefrom. In the second embodiment the upper surface of the envelope is pressed downwardly by a weighted plate, detachable weights being provided to select the pressure required. Scraper blades are arranged at each end of the fountain roller to prevent ink escaping via the peripheral ends thereof. In yet a third embodiment the pressure plate is moved against the envelope manually in a step-by-step arrangement which utilizes the application of predetermined cam surfaces, the application of each successive surface applying increased pressure to the plate and hence the envelope.

Abstract: 1355223 Transistor synchronous detectors; colour television RCA CORPORATION 11 Nov 1971 [16 Nov 1970] 52347/71 Headings H3T and H4F A synchronous detector, for use as the Q-axis chroma demodulator of a colour T.V. receiver, consists of a demodulating stage T52, T54, T62, T64 fed by a differential amplifier T12, T14 which receives the input signal; and further includes means such as T82 which diverts at least some of the quiescent current away from the differential amplifier to reduce the amplitude of the final detector output signal, but which also re-inserts the diverted current into the demodulator stage to maintain the D.C. levels of the output unchanged. The reduction of the detector output signal subdues the blue and green portions of a picture when flesh tones appear, whereas the constant D.C. level maintains the colour shading of the rest of the picture. The demodulator stage provides low and high outputs at 32, 33 when the input and reference signals are in phase, due to simultaneous conduction of T12 and T52 or T14 and T64. When the reference and input signals are out of phase the outputs 32, 33 are high and low respectively. A signal on T82 base virtually disables the detector by drawing all quiescent current to the source T72 from load resistors R31, R30 via diodes 34, 35. In embodiments permitting continuous variation of the amount of diverted current, to proportionally control the detector gain, two diverting transistors and no diodes are used (82, 182, Figs. 2, 3, not shown) their collectors being directly connected either to the output terminals 30, 32, or to the commoned emitters of the respective emittercoupled pairs of the demodulator stage.
