Abstract: 866,659. Gravity-separation apparatus. PAUSER, O. Aug. 14, 1959 [Aug. 25, 1958], No.27827/59. Class 46. A device for removing dirt floating on the surface of swimming pools and the like comprises a floatable cup-like container into which surface water enters through an inlet, the bottom of the container being connected to a suction line per- , mitting changes of location of the container and the container being provided at its inlet with a float-controlled shut-off element which, when the level of liquid drops under the action of suction in the container, sinks with its upper edge below the surface of the liquid outside the container but, in the absence of suction, lies with its upper edge above the surface of the liquid. A container 11, Fig. 1, kept afloat by float boxes 19, has the upper edge of one of its walls, 11d, Fig. 2, just beneath the surface of the water ; the container is connected at 12 to a suction hose 13. On suction being applied, a flap 15, normally maintained in the vertical position by a float 16, is turned about a pivot 14 to permit surface dirt to flow into the container and through the hose. In order to prevent accidental emptying of the container by undue suction, the upper edge of the flap 15 may be linked to a flap valve over the outlet 12, Fig. 5 (not shown). Sail surfaces 20, Fig. 1, may be provided to ensure that the device is blown by the wind into corners &c. where the dirt is blown. An inlet opening may be provided also on another side of the container. It is stated that devices are already known in which a transportable apparatus equipped with a suction pump and with a flat nozzle is guided just under the surface and sucks off water and accumulated sludge and dirt. It is also said to be known to remove sludge suspended at intermediate levels by means of a collecting container suspended from a rockable arm and having a verticallyadjustable inlet edge, the collected sludge being pumped pneumatically to further containers. The device of the invention may be connected either to a fixed suction device or to the abovedescribed underwater suction-cleaning device, in the first alternative the device may be connected by telescopic, but otherwise fixed, pipelines.

Pivoted on the bridge 15 are contact rockers 18, 19 adapted to be engaged by a tumbler 17 so that when the tumbler is moved to the left the contacts on rocker 19 are moved, and when the tumbler is moved to the right the contacts on rocker 18 are moved, the central position of the tumbler giving an off position for both sets of contacts. Rocker 18 carries three contact bars 21 each having a single blade 25, 27 so that on moving the tumbler to the right the two sets of contacts are bridged straight across. The rocker 19 carries two contact bars 31, 32, the bar 31 having a single blade at each end. The bar 32 has a pair of blades at each end, the members of each pair being connected together, but the two pairs being insulated from each other. Thus on moving the tumbler to the left the bar 31 bridges contacts C, F while the pairs of blades on bar 32 connects contacts A, B and D, E. Diagrams are given showing how the switch can be used for reversing the connections of a three-phase A.C. motor and of shunt and series wound D.C. motors. In a modification, the rockers 18, 19 each carry two bars and each bar is provided with a pair of blades at one end and a single blade at the other end, all three blades being connected together. The pairs of bars are arranged so as to place the single blade of one bar adjacent the double blade of the other bar. This is stated to be useful for reversing a split-phase A.C. motor in combination with a centrifugal switch. Also it can be used for reversing a shunt wound D.C. motor in which case the motor is isolated from both poles of the supply in the off position of the switch.

Abstract: 463,198. Range finders &c. VICKERS-ARMSTRONGS, Ltd., and WATSON, J. P. Oct. 15, 1935, No. 28443. [Class 97 (i)] Relates to apparatus for measuring the inclination of a ship &c. to the line of sight by measuring the angle alpha subtended by the ship at the point of observation, this angle being equal to LSinI /R, L being the length of the ship, R its range and I the desired angle of inclination. The means for measuring the subtended angle comprises a split objectglass 3, 4 receiving rays from the observed ship after reflection at a stabilized mirror 1 and transmitting them to an eyepiece. The part 3 can be displaced relatively to the part 4 by a motor 9 rotated by a transmitter 10. A range motor 11, which continuously receive the range of the observed ship &c., rotates a disc 12 having a slot 13 of such form as to impart to a link 15 a displacement proportional to 1/R, this link being connected to a pivoted link 16 which, at a point 19 along its length, is connected to a member 18, the point 19 being displaceable by a member 20 movable, by rotating a handle 23, in accordance with L, so that the displacement of the member 18 is proportional to L/R. This displacement is transmitted by the gearing shown to a member 22 which is thus displaced diametrically over a rotatable disc 23Y proportionally to L /R. The member 22 carries a slider block 22B engaging a slotted arm 241 of a T-shaped member so that the arm 24 of the said member receives a displacement proportional to LSinx/R. The arm 24 operates the transmitter 10 connected to the motor 9. The disc 23 can be rotated by a motor 28 connected to a transmitter 29 controlled by a hand wheel 30. The operator, looking through the eyepiece of the observing instrument, turns the wheel 30 until the two images of the target touch each other. The angle x is then equal to the required angle I and the angle of rotation of the wheel 30 is a measure of this angle. An auxiliary apparatus of known form may be provided as shown for displacing the half lens 4 in the event of a breakdown of the above-described means for moving the half lens 3.
