Filed: 1972-03-28
Abstract: 1392084 Oil filter with reverse flow cleaning ATLAS AS 28 March 1972 [30 March 1971] 14471/72 Heading BID Filter elements in a housing E are periodically cleaned by reverse flow of filtered oil from a downstream reservoir K, which is vented at L during filtering to allow it to fill, valves L and G being then closed, and compressed air supplied through valve O to create a high pressure in the top of the reservoir which creates an initial high speed reverse flow when valve G is first opened, after which reverse flow continues at a lower speed but for a relatively longer period under a continuous supply of compressed air through restriction R. Filter cake and oil are displaced from around the elements (top left) into the lower part of the housing which incorporates two settling chambers P 1  and P 2  acting in parallel, and through these oil is displaced back to unfiltered oil tank A. Settled solids and water are periodically discharged at S under control of detector T. Reservoir K may be heated to 75‹C and a heater D is supplied for unfiltered oil, which removes solidified paraffin from the elements. Each element may comprise an elongate box with two pleated walls of filter cloth and an internal perforate outlet and support tube leading to manifold F. The reverse flow rates may correspond to 10 times and twice the filtration flow rate during the two cleaning stages, with pressures in similar ratios.

Filed: 1952-06-10
Abstract: 710,818. Gas turbine plant. CHERTOFF, I. June 10. 1952 [June 12, 1951], No. 14551/52. Class 110(3) [Also in Groups XII and XXIX]- A combustion chamber for gas turbines, pulse jet and ram jet engines has a cone-shaped member inserted just beyond the firing point for the charge, to give a shaped or hollow charge (Munroe) effect to the gas-flow. In Fig. 1 a turbine 11 is supplied with working fluid by a number of combustion chambers 16 containing cones 15 which are fixed to the periphery of a rotor disc 13. The disc is driven initially by a small electric motor or petrol engine, and afterwards in synchronism with the turbine by transmission means. Air and fuel mixture enters an inlet 18. is fired by means 20 and the products pass to the turbine through ducts 17, 19. The time gaps between firings of each combustion chamber allows it to cool. Extra cooling air may be injected into the casing 12, beyond the duct 19. Fig. 2 shows a combustion chamber 52 for a pulse jet type engine having intake louvres 58, fuel nozzles 57, a spark plug 59 and a cooling jacket 50. The cone 60 is formed of a number of segments which open up under pressure of the expanding gases under the action of ends 55 which slide on cam surfaces 56. Normally the segments are kept in position by means of springs. In Fig. 4, two cone-shaped grids 67, having connector tips 68, are used to provide an electromagnetic field, or electrostatic potential. A di-electric lining 66 supports the grids which are connected to leads 71, 72. The electrostatic potential or electromagnetic field is stated to resist the passage of fuel-air mixture and combustion products through the grids until the current is switched off. The apparatus may be adapted to ram jets, by keeping the charge or field on continuously, replacing the louvres 58 by a closure and injecting air and fuel continuously through nozzles 57. Various shapes of cone grids are described in the Specification.

Title: Improvements relating to mechanisms for applying adhesives to the flaps of packets and other like purposes
IPC: B65B51/02
Filed: 1927-05-31
Abstract: 294,332. Berkshire Printing Co., Ltd., Brooke, N., and Ballard, R. May 31, 1927. Endless-chain conveyers with flap carriers.-In devices for applying adhesive to the flaps of packets &c., a packet is caused to advance between guides e, by a conveyer chain c carrying arms d. The arms d on the conveyer chain c which move the packets, carry a short arm d', which, at the end of the travel, strikes a piece 10 and causes the arm to swing in towards the chain (Fig. 3), by engagement of the cranked part 2 with the plate 3. This position is maintained by the plates 4 and 5 (Fig. 4), until each part 2 reaches a gap 6, across one end of which .lies a pivoted' piece 7. If the abutment 7 lies across the gap, the arms d remain in an inoperative position, but if not, it causes the parts 2 to ride on the outside of the bar 8 and thus holds the arms d in operative position. The piece 7 is arranged under the.control of, for example, a machine for filling and folding the packets, so that the machines .may work together or independently. Specification 262,582, [Class 94 (i), Packing &c.], is referred to.

Abstract: 1,167,203. Measuring radio-activity. BECKMAN INSTRUMENTS Inc. March 31, 1967 [April 11, 19661, No. 14819/67. Heading G1A. Apparatus for measuring the radio-activity of a series of samples is provided with programming devices which can be positioned in a sample position on a conveyer and control the measurements to be performed on subsequent samples. Samples containing a radio-active substance and a liquid scintillator such as PPO or POPOP are transported in bottles 18, Fig. 1, by a chain conveyer 12, 14, 16 to a station 34 where they are lowered to.a pair of photo-multipliers in tubes 52. A programming device 10 having a plurality of holes which may be selectively closed to set up a program may be fitted into a chain link. A photo-electric device comprising a lamp 42 and an array of photocells 48 produces signals from which a logic circuit Figs. 3 and 4 (not shown) determines whether a bottle, a programming device or an empty link is located at station 34. If an empty link is detected the sprocket 32 steps the conveyer on to the next position. If a programming device is detected, the photo-electric device reads the programme set upon it and writes it into a magnetic core store. If a bottle is detected, it is lowered, and the stored programme is carried out. If the programme specifies that no counts are to be made on the next set of samples, the samples are not lowered to the counting position.
