Title: Improved settling tanks
IPC: B01D21/00
Filed: 1946-05-09
Abstract: 635,611. Gravity-separation apparatus. SEAILLES, J. C. May 9, 1946, Nos. 14094, 14095, 14096 and 14097. Convention dates, May 11; 1945, July 27, 1945, July 31, 1945 and March 21, 1946. [Class 46] A settling tank comprises a container with one or more sets of parallel plates having a uniform inclination from top to bottom and with their lower edges substantially in a horizontal plane, the plates being supported between vertical side plates, and the liquid to be clarified is caused to flow towards the bottom of the plates and thereafter to flow upwardly between the plates before it can be discharged through an outlet near the upper ends of the plates. In the construction shown in Fig. 3, two box-like containers 36 each provided with a set of parallel plates 37 are mounted in a tank 35. Liquid is clarified as it passes up between the plates 37, and is withdrawn through pipes 40, the sediment being removed through an outlet provided with a valve 41. The containers may be adjustable or may be given vibratory movement whereby sediment lying on the plates is removed therefrom. The plates may be corrugated or, as shown in Fig. 10, may be, V-shaped, the sediment converging to the troughs of the plates 62 and being directed to a narrow channel 64. Such an arrangement is also shown in Figs. 12 and 13, in which liquid enters tank 82 through pipe 83 and after passing up between plates 85 is discharged clarified through outlet 84. Sediment from the plates 85 is directed through channel 86 to a lower set of plates 87 where further settling takes place, the sediment passing to outlets 92 and more clarified liquid flowing upwardly to outlet 84. Containers incorporating the parallel plates may be provided with compartments which enable the containers to float in the settling tank. The Specification as open to inspection under Sect. 91 comprises also tanks fitted with sets of plates 50, Fig. 23 (Cancelled), provided between partitions 51 and formed with bent ends 52 so that mixing of sediment with the incoming liquid is reduced. In the construction shown in Fig. 24 (Cancelled) the plates 50 are associated each with a smaller plate 53 to form channels through which the sediment passes. This subject-matter does not appear in the Specification as accepted.

Title: Scanning electron microscopy
IPC: H01J37/28
Filed: 1976-04-07
Abstract: 1526533 Scanning electron microscopy AMERICAN OPTICAL CORP 7 April 1976 [7 April 1975] 14206/76 Heading H4F A microscope of the type in which a specimen is raster scanned by a beam of charged particles includes a detector responsive to particles from the specimen to provide a video signal which is fed to a c.r.t. display. The scanning is so arranged, and the video signal so blanked, that different images, e.g. a stereo pair, are displayed on different parts of the screen during respective successive fields. In one arrangement, using a single detector, the beam of particles, e.g. electrons, ions, or X-rays, scans the specimen at a first average angle during odd-numbered fields and at a second average angle during even-numbered fields in order to provide stereo images. The scan of the specimen and the scan in the c.r.t. are synchronized. The line scan waveforms deflecting the particle beam during the odd and even fields are phase displaced in respective opposite directions relative to the line scan waveform of the c.r.t., and the video signal fed to the c.r.t. is blanked so that an image appears only on the left-hand side of the screen during odd fields and only on the right-hand side during even fields. In order to prevent misalignment of the stereo images when the magnification of the microscope is changed the displacement is such that the centre of the line scan interval in odd fields coincides with the vertical centre line of the left hand half of the c.r.t. display, and in in even fields coincides with that of the right hand half. The resulting stereo pair may be viewed by an observer using a suitable optical device. In a second arrangement, again two images are displayed side by side on the c.r.t., using phasedisplaced line scan waveforms as described above, but the images are derived from detectors responsive to different forms of radiation. For example one image may be the back-scattered electron image of the specimen and the other the secondary electron image.

[Class 72.] A motor vehicle axle is formed to the described shape by the press shown in Figs. 16 and 17. The axle is heated and placed between dies 47, 50. The lower die 47 is carried by a plunger 51 pressed upwardly with a constant predetermined pressure by hydraulic pressure in a cylinder 52. The upper die 50 is carried by a plunger 56 working in an hydraulic cylinder 57. When pressure is admitted to the cylinder 57, the upper die is forced down and forms the axle to the desired shape, the upward pressure of the lower die being sufficient to ensure this. A sufficiently greater downward pressure is then applied to the upper die to overcome the upward pressure of the lower die so that both dies and the axle are forced downwards into an annealing or quenching bath 55. Since the axle is still held firmly in the dies warping is prevented. The lower die is provided with a follower plate 48 pressed by springs 49 which give under the pressure of the upper die but ensure that this die has a firm grip on the axle.
