Filed: 1954-03-19
Abstract: 751,133. Filters. ZDANSKY, E. A. March 19, 1954, No. 8101/54. Class 46. A radial filter assembly especially for use with filter aid is characterized in that the filter elements are arranged radially about a central filtrate collector space and have the form of quadrangular plates each consisting of two parallel and mutually supported filter membranes the interstice between which is closed on the three outer edges of the quadrangle, and on the edge towards the centre of the radial arrangement is provided with filtrate openings, the latter edge being widened by distancepieces which in the assembly of the elements form a closed tubular jacket with vertical axis surrounding the central filtrate collector space, the jacket being held together at top and bottom by clamping-rings. Filter leaves each comprise a coarse supporting mesh 1, Fig. 3, covered on both surfaces by fine-mesh wire cloth 2, 2a, the interstice Z being closed on three sides, Fig. 1 (left-hand side), by a metal strip 3 or a fused-on layer of metal. The inner edge is provided internally with packing-strips 6 projecting for from 2 to 20 mms. outwardly to prevent penetration of filter cake into the angles between the leaf and two bars 4 (acting as distance-pieces) between which it is gripped. The bars 4 alternate with the leaves and are reduced in thickness at top and bottom, as shown, so that they can be held in place to form a tube by rings 20, 21, which are drawn towards each other by a filtrate discharge pipe 24 welded at the top to a flange 25 (to which the ring 20 is also welded) and secured by screws 26 at the bottom to a flange 27 on which the ring 21 is seated. Packings 9, Fig. 3, and 22, 23, Fig. 1, are provided. In Fig. 4 and the righthand side of Fig. 1 stainless steel wire cloth sheets 12, 12a, are welded to a trapezoidal frame 11 and to inclined strengthening and dividing cross-bars 15, each apertured at 16 to ensure escape of air from the compartments into which the bars divide the leaf when liquid to be filtered is admitted to a vessel in which the filtering unit is located. Distance-pieces 17 are welded, one to each side of the inner edge of each leaf. The plates of Fig. 3 are suitable for use with a thick layer 7 of filter aid such as asbestos and cellulose producing a high pressure differential, while with those of Fig. 4 kieselguhr 18 is used.

Abstract: 1,215,254. Remote measuring apparatus. ISTRINSKY FILIAL VSESOJUZNOGO NAUCHNOISSLEDOVATELSKOGO INSTITUTA ELEKTROMEKHANIKI. Feb. 17, 1969, No.8389/69. Heading G1N. In a electric drill inclinometer, the angles of azimuth and inclination and the angular position of the drill deflector, as determined by phase transmitters 7, 7<SP>1</SP>, 7<SP>11</SP>, are transmitted to the surface over the drill power supply line 1. The control winding of each transmitter, which also includes a rotor and stator, in simultaneously energized by two voltages which are at the frequency of the r.f. oscillater 6 and which are amplitude modulated by the frequency of the supply voltage via filter 3, phase 4 and modulaters 5, 5<SP>1</SP>. The phase of the modulated voltages at the transmitters' output depend on the position of their rotors, is on the values of the angles being measured. Detectors 8, 8<SP>1</SP>, 8<SP>11</SP> simultaneously accept voltages from the respective transmitter and oscillator 6. The detectors' outputs have their phase angles changed in proportion to the angles being measured, and are applied to a time multiplexer 9 whose output is a low-frequency pulse-train, each pulse train corresponding to a particular position of the drill. The low frequency pulse train is then applied to a frequency changer including switches 10, 10<SP>1</SP> and r.f. oscillators 11, 11<SP>1</SP> and the r.f. pulse train is transmitted to the surface via amplifier 12 and power line 1. The pulse train is decoded at the surface and converted into D.C. voltages proportional to the magnitudes of the angles being measured. Voltages may be displayed visually or recorded permanently.

Abstract: 364,943. Coke ovens. STILL, C., Recklinghausen, Westphalia, Germany. March 20, 1931, No. 8621. Convention date, March 22, 1930. [Class 51 (ii).] Eight regenerator tunnels separated by strong load-supporting walls and running parallel to the length of the battery are built into the substructure of a coke oven. In the arrangement shown the tunnels are connected in pairs, and the two outer pairs R are used for preheating gas or air, according as lean or rich gas is used for combustion, while the inner pairs L are used exclusively for preheating air. The tunnels R may be subdivided into compartments corresponding in number with the heating walls. The pairs of tunnels R, L are connected respectively to half-length sole flues c, d, and these in turn are connected through passages i, j to ports e, o in the partition walls between the vertical flues H. When lean gas is used for combustion preheating of gas and air is effected in the tunnels R, L at, say, the right-hand side of the ovens, combustion is effected in all. the flues of the right-hand halves of the heating-walls, and the flues and regenerators at the left-hand side serve for downflow and outflow. The mains g can be connected either with the regenerators R through the pipes g when lean gas is used, or with the passages a at the base of the heating- walls for rich gas heating. The upper ends V of the tunnels are corbelled, and inspection passages U lead to the upper ends of the tunnels R.

Filed: 1919-04-07
Abstract: 134,752. Tidswell, H. R. April 7, 1919. Calculating - ap- paratus; tabular cal- culators. - Apparatus for determining the sex of children before birth is based on the theory that ovulation arises from the ovaries in turn, and that one ovary always produces male ova and the other female. Various forms of ap- paratus for facilitat- ing the computations are described. In t h e construction shown in Fig. 1, a drum C is graduated spirally as shown; each spiral strip is divided into lengths denoting the same or the opposite sex relatively to the last child born, and five sets of such graduations are provided to allow for ovulation periods varying from 26 to 30 days. A co-axial drum B is gradu. ated in dates and a third drum D carries a bar E graduated in years and provided with a cursor F having a pointer giving a distance from the bar equal to 365-280 days. In using the device, the bar E is set to the date of the last child, the drum C is turned to zero with respect to the bar, the bar is then set to the date of the ex- pected birth, and the spiral corresponding with the number of elapsed year and the ovulation period in question shows the sex against the bar. In other forms, superposed graduated disks are employed, and where provision is not made on the device for various ovulation periods, a chart may be used showing results for other periods given the result for the normal period.
