Title: Improvements relating to centrifugal machines
IPC: B04B9/12
Filed: 1929-01-29
Abstract: 306,079. Sharples Specialty Co., (Assignees of Ayres, A. U.). Feb. 15, 1928, [Convention date]. Suspending; feeding.-The lower end of the bowl 21 of an over-driven separator has a cap 22 provided with a tubular central boss 23 resting in a bearing 17 made preferably of some self-lubricating material or of wood impregnated with a lubricant. This material is carried in a metal ferrule 18 resting on a washer 20 held up by a spring 19, the bearing being retained by the flange 15 on the shell 14. A nozzle 28 screwed into the connector 24 enters the tubular boss' 23 and is in connection with the supply passage 26 from the socket 27 to which the supply pipe is attached. The connector is held in position by a collar 25 which engages a flange on the connector so that this part may be clamped in any position to correspond with the position of the supply pipe. When the machine stops, liquid will drain from the bowl 21 through the passage 32; openings 30 in the shell 14 permit drainage from the casing 10.

Patent GB-284632-A (GB)
Title: Improved liquid level indicator
IPC: G01F23/40
Filed: 1928-02-01
Abstract: 284,632. Caretta, E., Feb. 1, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Indicators actuated by floats.-In liquid-level indicators of the kind in which the indicator is operated by hand to an extent dependent on the level of a float, and comprising a float and associated slider moving along a vertical guide, means are provided to prevent locking of the slider on the guide due to inertia under the action of a sudden manipulation of the indicator. The float 6, Fig. 2, is pivoted at 4 to a slider 3 sliding over a vertical guide 1 having a rack 2 which is engaged by a tooth 7 on the arm 5 when the float is lowered to liquid level. To prevent premature engagement of the tooth 7 with the rack, a plate 10 is pivoted at 9 to the slider 3 and has an opening through which projects a pin 12 attached to the arm 5. In normal use, when the float 6 is raised by buoyancy, the pin 12 enters the recess 13 of the opening in the plate 12, and engagement of the tooth 7 with the rack is not obstructed. If the slider 3 is suddenly lowered, inertia causes the float 6 and plate 10 to rock about their pivots in opposite directions, and the pin 12 is retained below the shoulder 14 in the opening in the plate, so that the parts become locked. Several modifications based on the same principle are described.

IPC: B63B39/02
Filed: 1967-01-20
Abstract: 1,164,665. Roll stabilizer. VOSPER Ltd. 12 Jan., 1968 [20 Jan., 1967], No. 3203/67. Heading B7M. A roll stabilizer for a floating body comprises a member 10 rotatable about an axis longitudinal of the body, and means effecting rotation of the member in a direction to reduce roll. In Fig. 1 roll sensing apparatus 14 controls the magnitude and direction of torque of a pumpmotor unit 11. When the ship rolls in one direction hydraulic fluid passes from accumulator 13 to sump 12 so that unit 11 drives wheel 10 in a direction to reduce roll. When the ship rolls in the other direction the wheel drives the unit 11 which pumps fluid from sump 12 to accumulator 13. The wheel may be replaced by a chain extending around the interior of the hull and possibly also over deck superstructure.

Abstract: 753,736. Electrodialysis. ROHM & HAAS CO. Feb. 3, 1954 [Feb. 11, 1953], No. 3210/54. Class 41. A process for separating from an aqueous solution of ionizable materials, a fraction thereof which is less concentrated in the material, comprises passing a portion of the solution through a plurality of multiple ion exchange membrane electrodialysis cells 1, 2 connected in series in such a manner that in each succeeding cell, e.g. 2, one portion of the depletion stream 4 of the preceding cell 1 is the depletion stream 4d, and another portion thereof is the concentration stream 4c. Feed enters the cell 1 at 3 and is divided into two streams 3d, 3c, the first forming the depletion stream 4 and the second the concentration stream 5 which may be led to waste or to be treated to recover solutes. The concentration stream 7 leaving cell 2 may be taken to the stream 5 or introduced into the stream 3d. The stream 4d may be higher in volume, e.g. by ten times, than the stream 4c, whichmay be passed in countercurrent at a lower rate through the cell 2, and so on in any succeeding cells. Specifications 719,315 and 721,161, [Group IV (a)], are referred to.

Title: Orthoprinter
IPC: G01C11/04
Filed: 1975-01-24
Abstract: 1488603 Photogrametry BENDIX CORP 24 Jan 1975 [15 Feb 1974] 3273/75 Heading H4D In an orthoprinter for printing an orthoprint from an angle α from the vertical stereo aerial photograph, a system utilizing a simplified scanning pattern suitable for laser scanning and printing is used, the system comprising means for scanning the photograph and means for printing the orthophoto and wherein means are provided for controlling the scanning and printing means to scan the photograph and print the orthophotograph along nadir lines which are defined as being lines (X, Y, N) extending radially on the orthoplane from the nadir point N vertically beneath the perspective centre of the photograph 0 (Fig. 1). The orthoprinter comprises control circuit 11 (Fig. 6) which supplies scanning signals and rotation signals α 1 (t) to photo scanner 13 and printing signals and rotation signals α 0 (t) to printer 16. The printing process may be performed in incremental stages of equal area portions of photo 4, the increments being square or hexagon. Alternatively, continuous increments or strips may be used in the form of a square spiral, concentric circles or a circular spiral (see Figs. 8, 9, not shown). The scanning control 11, provides rotation signals α 1 (t) to scanner 13 and α 0 (t) to orthophoto printer 15 to maintain alignment with the nadir lines (see Figs. 4 and 5, not shown). Control 11  also provides signals I(t) to the printer for regulating the printing intensity to compensate for the non-uniform. raster-line spacing in each increment. Digital video processor 17 provides a variable time delay signal #t(E) obtained from the stereophoto information regarding the terrain elevation to the printing means to correct for geometric differences between the photograph and orthophoto, due to the angled view of the photograph. In the embodiment of Figs 10 and 11 the value of α 0 (t) is maintained constant within each increment, and printing intensity is kept constant. It is stated that the error so introduced is such as to be acceptable when using cameras of long focal length.
