IPC: B01F15/04
Abstract: 134,615. Menzies, S. H., and Magrath, H. J. Nov. 5, 1918. Gas meters. - In apparatus for measuring and delivering determinate quantities of gases, particularly noxious gases, such as chlorine for water purification, comprising a chamber which is filled to a predetermined pressure and then discharged until the pressure falls to the normal, the volume of the measuring-chamber can be altered, and the inlet and outlet valves are manipulated through diaphragms to avoid leakage. As shown, a measuring-vessel a, Fig. 1, is provided, having a pressure gauge c capable of actuation through a diaphragm b. It is closed at the bottom by a removable cap d, and its volume is altered bv the use of different caps, or by the insertion of bars which are held in position by pins on the caps and at the top of the vessel. Passages f, f communicate with the vessel and with chambers g, g<1>, Figs. 3 and 4, containing needle valves l, l<1> normally held on their seats by springs m, m<1> acting on cross-pieces connected to rods secured to yokes carrying the valves. The cross-pieces rest against diaphragms q, q<1> which may be acted on by press-buttons t, t<1>. The inlet and outlet passages u, u<1> which communicate with passages leading to the valve seats are provided with porous plugs to regulate the flow of gas. The button t is pressed, by hand or mechanically, and the vessel a filled through the valve l and passages f to the desired pressure. The button t is then released and the button t<1> pressed, whereupon the measured quantity of gas is discharged, either through a diffuser into the whole quantity of liquid to be treated, or into a small quantity of liquid to form a strong solution to be mixed with the bulk. Correction of the gauge for temperature may be made by a table of corrections, or by the use of a gauge with a suitable compensation device. The device may be actuated mechanically by the use of cams controlling the buttons, pushing the button t past an electro-magnetic catch, which is released when the pressure attains the desired value, by the closing of a contact.

Title: Method of automatic follow-up of the focusing of a microscope equipped with a television camera
IPC: G02B21/24
Filed: 1977-04-04
Abstract: The focussing drive (4) is moved into an initial position by manual tripping by the observer or by automatic tripping at prescribed instants. The search run starts in the opposite direction starting from said position. At the same time, a specific high-frequency band whose signal intensity is used as an objective criterion for the image contrast is filtered (8) from the video signal of the camera and rectified (10). Upon overshooting of the optimal focussing, the image has maximum contrast, and the rectified signal therefore achieves a maximum. Thereupon, the drive (4) is reversed and there is backward motion at the same speed over a specific time interval. This interval is fixed by the instants of the maximum detection of the rectified signal and of the reversal of the drive. <IMAGE>
