Title: Improvements in and relating to the conditioning and filtration of water and other liquids
IPC: C02F1/52
Filed: 1950-01-31
Abstract: 675,322. Purifying water; treating sewage; separation gravity apparatus; filters. HILL, F. G. Jan. 31, 1950, No. 2471/50. Class 46, and 111 In a conditioning and filtering plant for water, sewage or oils comprising a flocculating chamber, a clarifier chamber and a filtering chamber arranged in series the distribution of the water in the respective chambers is effected by a plurality of conduits located at the bottom of the chamber and spaced from one another and extending over the whole area of the chamber, each conduit having a plurality of downwardly - directed outlets through which the water is discharged to flow upwardly through the spaces. Water from a main 5, Fig. 1, passes through pipes 6 having venturis 8, and opposed outlets 7 to cause turbulence, into a mixing chamber 1, reagents from dry- or solution-feed machines being introduced at 8. The water passes over and under baffles 9, Fig. 2, and over a measuring weir 10 into distributing channels 12, Fig. 4, formed between outer and inner walls of a flocculating chamber 2. The channels communicate with the open ends of a number of concrete conduits 13, supported by webs 14 having holes 14a. (Identical conduits 31 for the filter chamber 4 are shown on a larger scale in Fig. 9.) Water issues from a number of downwardly-directed openings 21, Fig. 10, in the conduits 13 and rises through converging spaces 17, narrow gaps 15 and diverging spaces 19. The flocculator effluent then passes from three longitudinal channels 22 to parallel distribution channels 25 formed between side walls of a clarifying chamber 3, which differs from the flocculator only in being longer and Wider, arid finally from the effluent channels 27 of the clarifier to downpipes 29, 29a connected to distributing channels 30 at the base of a filter 4, Fig. 6. The channels 30 are covered at their tops by slabs 32 so that they may be maintained under pressure if necessary. Grid pipes comprising a central pipe 33 with pairs of side pipes 34, or a central pipe 35 with single side pipes 36, Fig. 9, are laid parallel with the conduits 31 and spaced from them. and from one another a distance of 1/16 inch or 3/32 inch to retain the filtering medium . without the interposition of pebbles or the like. The final effluent leaves by channels 37 and pipe 38. In washing the filter it is first drained downwards through pipes 42, valves 41 being closed. Backwashing water is supplied by pipe 39a to pipes 39, downpipes 29a and conduits 31, assisted by automatic introduction of air through venturi tubes or aerators 40, the wash water passing away along the outlet channels 37. The flocculator 2 and clarifier 3 are provided with valve-controlled drain pipes 43, 44, respectively, connected to the distribution channels and chambers. The side walls of these chambers may alternatively slope upwardly and outwardly, and single grid pipes may be provided between the conduits 13 in each case.

Title: Optical equipment for the accurate setting and reading of the amount of shift of a slide in a machine
IPC: B23Q17/24
Filed: 1960-01-27
Abstract: 894,525. Machine-tool details. HENSOLDT & SOHNE OPTISCHE WERKE A.G., M. Jan. 27, 1960 [Feb. 11, 1959], No. 2898/60. Class 83 (3). [Also in Groups XIX and XX] In a machine-tool having a fixed female slide and a male sliding part, the fixed slide carries a measuring scale and the sliding part carries a scale-reading device or vice versa, and an optical system of the scale-reading device projects an image of a section of the measuring scale upon a graticule, the light path being directed via optical elements one, at least, of which is mounted on a part of the machine not participating in tilt if the sliding part tilts and serves to compensate tilting errors due to faults in the female slide by shifting the position of the scale mark image, there being also at least one other optical compensating element which is adapted to produce an additional compensating shift of the scale mark image, the magnitude of said shift depending on the height of the workpiece. The optical component or components for compensating tilt may be reflecting prisms such as 10 (Fig. 1), supported on a rigid portion 1 of the machine, the rest of the optical system being mounted in the slide 6 carrying the tool 4, a variable-focus objective 9 being adjusted in a predetermined manner in dependence upon the height " a " of the workpiece 3 to maintain proper compensation for any given value of " a." Other arrangements include pendulous mirrors and/or polarizing filters for tilt compensation and means for varying the effective number of reflecting surfaces, in dependence on "a," to alter the optical path length in the system (Fig. 8). Alternatively, optical components may be supported on a parallelogram linkage (Fig. 12), adjustable in dependence upon the value of " a " to deflect the image-carrying beam so that for a given tilt of the slide, the image of the scale mark is directed on to the same graticule position independently of " a." Another method of adjustable deflection of the beam is shown in Fig. 7 wherein a cam 82 is adjustable in height in dependence on "a" altering the relative inclination of prisms 78 and 79. The embodiment of Fig. 14 provides for the displacement of a beam parallel to itself by an amount depending on the value of " a."

Abstract: 1,168,250. Telegraphy; Pulse duration discriminating. C.I.T. COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. 19 Jan., 1967 [26 Jan., 1966], No. 2906/67. Headings H3T and H4P. A circuit for controlling a teleprinter in accordance with signals on a transmission line, particularly for disconnecting the apparatus at the end of a message, comprises first and second switching circuits actuated by a positive signal on the line to charge a capacitor and energize a relay, the receipt of a negative signal changing over the first circuit but the second circuit remaining in its actuated state until the capacitor has discharged to a predetermined level so that de-energization of the relay is delayed. In Fig. 2, the first circuit comprises transistors TR1, TR2 which are normally off but are turned on by a positive signal on the line RON applied through telegraph relay RT. Conduction of TR2 turns off the normally conducting transistor TR3, which forms the " second circuit " above, and allows conduction in TR4 and TR5. Relay M is then energized to connect the telegraph receiving apparatus (not shown) to the line and also close contact m1 to start the charging of capacitor C. During reception of a message, the " start " bit of the code is always negative so that the conduction states of transistors TR1 and TR2 will change at least once during the transmission of each code combination. When TR2 ;s cut off the capacitor discharges through R1, R2 and R3. If the line RON assumes zero or negative potential for more than a certain time, e.g. 1500 ms., the capacitor discharges sufficiently to allow TR3 to conduct, when TR4 and TR5 are cut off to de-energize relay M and disconnect the apparatus from the line.
