Title: Process of, and apparatus for, the automatic counting of particles of any size and shape
IPC: G06M11/00
Filed: 1954-06-23
Abstract: 791,079. Counting particles photo-electrically. FARBENFABRIKEN BAYER AKT.-GES. June 23, 1954 [June 26, 1953], No. 18435/54. Class 40 (3). Particles such as 4 (Figure 1) are counted by traversing their image in a line-by-line scanning fashion relative to a photo-cell and elongated electrodes 2, 3, the former of which is situated ahead of the recording cell and the other behind and below. The arrangement is that the cell 1 counts the particle, the image of the particle bridges the area between the recording cell and one of the auxiliary electrodes. The recording cell itself may consist of electrodes embedded in the same photo-electric layer as that in which electrodes 2, 3 are embedded. Thus, if the line spacing during the scanning is equal to the distance between electrodes 1 and cell 3 each particle is counted once only since during the scan when the second count would occur a bridge is formed to the second electrode. Similarly, as shown in Fig. 3, re-entrant particles are counted only once since a bridge is formed to electrode 2. Fig. 3a shows an arrangement in which, instead of using a continuous photoelectric layer, the electrodes 1a, 1b, 2 and 3 are separated by photo-electric strips, indicated by the block squares with metallic spots, indicated by the white filling of the squares. Fig. 3b shows a circuit for the arrangement. When the image of a light particle on a dark background falls on the light-sensitive area between spaced electrodes 1a, 1b triode ET conducts, operating a relay 13 which closes its contacts, thus operating a counter 14. Counter 14 is not energized, however, if the area from electrode 1a to one of elongated electrodes 2, 3 is bridged by the light image of a particle since a second triode conducts and relay 13a opens the counter circuit. The recording cell may constitute a separate photo-cell instead of electrodes embedded in a photo-electric layer and the elongated electrodes may be replaced by elongated photo-cells. To detect the bridging between the secondary and elongated cells additional cells may be arranged between them. The cells in this last arrangement may be of the electron multiplier type.

Title: Cameras apparatus for driving tubes into the ground
IPC: G03B9/70
Filed: 1973-04-18
Abstract: 1430158 Flash arrangements for cameras AGFA-GEVAERT AG 18 April 1973 [28 April 1972] 18755/73 Heading G2A A camera comprises a drive member 1, which actuates both a shutter 16 and an ignition member 8 for percussively ignited flash-lamps, and a control member which, when there is no flash-lamp mounted in the camera, disengages the ignition member from, and brings retarding means 51, 52, 53 into engagement with, the drive member. The drive member 1 is biased by a spring 15 to rotate clockwise when released by shutter release 2. When no flash-lamp is inserted in the socket 6 (as shown in Fig. 1) a rod 12 protrudes into the socket under the influence of a spring 11 acting on a control lever 10 which co-operates with a stop 12a on the rod 12. This causes the ignition member 8, which is coupled to the lever 10 by a spring 9, and the retarding lever 51, which co-operates with a stop 10a on the lever 10, to be pivoted so that their ends 8b and 51 b lie in and out of the path of the stop 1b on the drive member respectively. Thus when member 1 rotates it actuates the shutter and is retarded by engaging and moving member 51 against the action of a spring 53 and does not strike the stop 20 with sufficient force to cause camera shake. If a flash-lamp is inserted in the socket 6 Fig. 2 (not shown) the rod 12 is pushed down and via the lever 10 and couplings described above moves end 8b into, and end 51b out of, the path of the stop 1b.

Abstract: 952,932. Film evaporators. IMPERIAL CHEMICAL INDUSTRIES Ltd. May 23, 1962 [May 25, 1961], No. 18919/62. Heading B1B. In an evaporator, Fig. 1, comprising a vertical cylindrical tube, which is externally heated, the feed liquid entering via inlet 8 passes down the inside surface of the hot wall 1 as a thin liquid film which is spread and agitated during its descent by the wiping action of a number of coiled helical springs 5, fixed to a central rotating shaft 2 by means of arms 6. Longitudinal baffles 7 are fitted to the shaft 2 to increase the efficiency of evaporation. The vapour formed in the tube is withdrawn via outlet 9, and the residue at the base of the tube is withdrawn via line 10. The ratio of the length of the tube to its diameter is from 5:1 to 50:1; and the tube may also be inclined at any angle to the horizontal, an angle of 10 degrees to 40 degrees being suitable when the residue obtained is a solid. The shaft rotates at such a rate that the peripheral velocity of the springs is in excess of 10 inches/sec. The springs are constructed from nichrome or stainless steel wire. An alternative embodiment of the invention has an inner unheated cylinder 11, Fig. 3, fixed to the shaft, the helical springs being mounted on the outer surface of this cylinder. Such an apparatus is also suitable for fractional distillation or molecular distillation of a liquid.
