Title: Improvements in liquid filters
IPC: B01D24/00
Filed: 1957-11-26
Abstract: 868,139. Filters. KOSKOWSKI, R. Nov. 26, 1957 [Nov. 26, 1956], No. 36870/57. Class 46. Liquid entering at C, Fig. 1, flows downwards through a perforate part b, between partitions q forming filter compartments f, through filter beds a in the compartments, and through a drainage bottom t, filtered water being discharged at D. Cleaning by reverse flow of the sand in one or more compartments is effected sequentially by a pump P above a suction device S which slides on the perforate part b, and preferably is provided with an imperforate screen O, the suction apparatus being suspended by a pipe r from a car k movable on rails m. The pipe r discharges into a gutter (not shown). The pump P and car k are driven electrically from a cable L. In Fig. 3 unfiltered water is drawn by a pump P on the car k through a pipe W and discharged into an upwardly-widening mixing- chamber n of the suction device S, thus creating upward flow in the affected compartments. This water passes up through a chamber g to a gutter h, while any bed particles drawn up with it return to the compartments through a slot i. In Fig. 5 the normal filtration flow is upwards into an inner chamber E, while rinse water is drawn downwards in certain compartments and up through a pipe W by a pump P for discharge at h<SP>1</SP>.

Abstract: 1,150,528. Repeated contact printing. S. NYGAARD. Aug. 11, 1967 [Aug. 17, 1966], No.37055/67. Heading G2A. A transparency M which is to be repeatedly printed stepwise on to a photographic film or sensitized printing plate is mounted in a holder K which is attached by buttons E 1 , E 2  to a slide bar B movable in a groove in a base plate A. The slider B has a row of equi-spaced holes D in which the buttons engage. A graduation mark L relates each hole to a mark on a scale S along the edge of plate A. In the example shown, the holes D are 1 cm apart. Slide B also has a second row of holes G similar to the row D, but staggered with respect thereto. Fixed over the edge of plate A is a transparent bar C, which covers the scale S and also part of slider B. Bar C has a row of holes H which are spaced more widely apart than those in rows D and G, e.g. 1À1 cm apart in the present example. In using the device, the holder K is initially mounted on slider B in the position shown, with button E 1  in the hole D corresponding to the zero mark on scale S. A third button E 3  is inserted into the first holes of rows G and H, which coincide. After the printing has been made, buttons E 1 , E 2  are removed, and holder K moved along to the next required position. If this displacement is a number of cm, button E 3  remains in its place. If the displacement required is not a whole number of cm but, for example, 12À4 cm, holder K is first moved along the slider until button E 1  can be inserted into the hole D corresponding to the 12 cm mark on scale S. The slider itself is then moved along until its fifth hole G coincides with the fifth hole H in bar C, and button E 3  placed through the two holes. Thus the slider will have been moved 0À4 cm, and the graduation mark L corresponding to button E 1  will indicate 12À4 cm on scale S.

Abstract: 904,564. Aerials. SHEPPARD INSTALLATIONS Ltd., and SHEPPARD, J. L. Nov. 19, 1959 [Nov. 19, 1958], No. 37251/58. Class 40 (7). An aerial system comprises a plurality of adjacent parallel pairs of open-ended elements, the pairs being mounted in spaced relationship along a support boom and one element of one pair being coupled to a feeder. In a simple embodiment a pair of parallel elements 3, mounted either one on either side of the boom 1 or both on the same side of the boom but spaced an equivalent distance apart, are approximately half a wavelength long at the frequency it is desired to receive. One of the elements is divided at its centre and the adjacent ends held in a polyethylene insulator and there connected to a suitable feeder. A slightly longer pair of elements 2, similarly mounted, form a director and a slightly shorter pair 3, again similarly mounted but on the opposite side, form a director. If required, the boom may be extended and additional pairs of directors, or single directors, added. If it is desired to receive signals of two different frequencies two additional elements 6, 6<SP>1</SP> may be added to the system. These are of L-formation and attached to the inner parts of the element 3 connected to the feeder. They extend along the boom to within a short distance of the reflector pair 2 and then diverge parallel thereto. They may be supported by insulating links 7 from the member of the reflector pair adjacent. Instead of the elements 6, 6<SP>1</SP>, being L-shaped they may form a single linear conductor supported on the boom and coupled to the same element 3 by Y-match connecting-rods (Fig. 6, not shown). In another variation they are straight and colinear and mounted in an insulator on the boom with their ends connected by a parallel wire transmission line to the fed element 3 (Fig. 8, not shown). A director for the additional frequency can be added and may consist of elements 11, 11<SP>1</SP>, supported by insulating clamps 12 from one of the original frequency directors 9, as shown in Fig. 5.
