Title: Improvements in or relating to the dehydration of fuel gases, and to the removal of napthalene therefrom
IPC: C10K1/08
Filed: 1933-09-14
Abstract: 422,636. Gas condensing and washing processes. WHESSOE FOUNDRY & ENGINEERING CO., Ltd., Darlington, GRANT, A. G., 86, Coniscliffe Road, and TAYLOR, A. E., 12, Cedar Road, both in Darlington. Sept. 14, 1933, Nos. 25465 /33 and 26419/34. [Class 55 (ii)] Fuel gases are dehydrated and naphthalene, benzene, and gum forming compounds removed therefrom by continuously spraying the gas with a mixture of brine and naphthalene solvent such as gas oil. The gas-is treated in a tower A fitted with nozzles Z, through which the washing liquid is projected, and with baffles a<3> which cause the gas flowing upwardly to take a zigzag path. Spray particles are removed from the gas by tower rings packed in a section a<4> and the gas is reheated before distribution by a reheater C. The brine flows from a separator B to a cooler G and is recycled to the sprayers Z by a pump H, the oil from the separator mixing with the brine prior to entering the pump H. Part of the brine-oil mixture may be byepassed to a separator S, brine-freed oil being removed from the system through a pipe b<8> and oil-freed brine concentrated in an evaporator F before re-entering the system through a funnel X. The brine-freed oil may be purified of its benzene, naphthalene, and gum forming compounds, and the stripped oil or fresh oil returned to the system. The brine cooler G is chilled by an evaporating ammonia stream flowing through the pipes c, c from a compression refrigerating plant M-K. Benzene may be separately recovered from the impure oil in a debenzolizing plant. Specification 376,257, [Group XIII], is referred to.

Title: Improvements to apparatus for the treatment of liquids
IPC: B01D24/00
Filed: 1954-09-03
Abstract: 801,011. Filtering liquids ; purifying water; treating waste liquids. SUTCLIFFE, SPEAKMAN & CO. Ltd., and EDWARDS, F. E. [Representative of Edwards, W. A.]. Dec. 5, 1955 [Sept. 3, 1954]. No. 25700/54. Classes 46 and 111. [Also in Group XXIX]. During normal operation of an apparatus comprising a filter 4, Fig. 1, (containing, e.g. sand and gravel) separated by a gauze screen 2 from a dechlorinator 7 (containing, e.g. activated carbon), in a cylindrical casing 1, the liquid to be treated (e.g. chlorinated water or a trade effluent) is supplied at 10 through a multiport valve 11 to the two parts downwards in series, and discharged through the same valve at 15. When the valve handle 16 is at the " west " position, port 18 in the valve plug connects 10 with 15, the casing being thus by-passed. When the handle 16 is in the " north-west " position the ends of pipes 10, 12, 14 and 15 are all obturated, the apparatus being thus shut down. The " north " position is for normal operation (Fig. 1). In the " northeast " position liquid entering at 10 passes along a port 19, Figs. 2 and 3, located in the valve plug in a plane behind ports 17, 18, and passes down the pipe 14 to the base of the dechlorinating part 7. The liquid rises through the easing 1, backwashing the dechlorinator and filter in that order and passing, some along pipes 21 and 22, and the remainder along pipe 12, through a further port 20, Figs. 2 and 4, in the valve plug, and into pipe 22. The filter alone may be backwashed by closing a valve 25 in pipe 14 and opening a valve 24 leading to a perforated pipe 23. The pipe lines of the apparatus may be sterilised by passage into them of filtered chlorinated liquid through pipe 23 and valve 24. Steam may be admitted through a valve 26, Fig. 1, to reactivate the carbon, valves 11, 21a, 24 and 25 being closed during this operation. A spring-loaded relief valve 27 is provided.

Title: Hydraulic device for controlling the movements in machines and apparatus for washing, filling, stoppering, capsuling, labelling and the like bottles and other objects
IPC: B67C3/24
Filed: 1946-08-28
Abstract: 638,978. Hydraulic machines. DETREZ, R. Aug. 28, 1946, No. 25707. Convention date, June 23, 1944. [Class 69 (ii)] In a device for hydraulically controlling the reciprocating movements of the supports for receptacles in machines for washing, filling, stoppering, capsuling, labelling, &c. bottles, cans, tins, &c., in which device the reciprocating movements are produced by hydraulic pistons, the reciprocations of which are produced by a pressure liquid distributer, the reciprocating movements of the supports for the receptacles present and hold the necks of the receptacles against operating members whilst one or more operations are carried out on the receptacles and remove the receptacles from the members after carrying out the said operations, the evolutions of said hydraulic pistons in their cylinders being determined by members acting independently of one another at desired moments, and during predetermined periods of time, on the valves of a liquid distributer connected hydraulically to each of the cylinders of which the piston is to be actuated, the members acting on the valves of the said distributer being synchronized in a positive manner with the machine or the group of hydraulic machines. Fig. 4 is a transverse section of the distributer to which has been added a driving cylinder A to show the successive functions of the valves controlling the reciprocation of its piston. The inlet valves 11, 11a are actuated by cams 3 on a cam-shaft 1, which latter is geared to drive a cam-shaft 2 for the outlet valves 15, 15a. Valves 11 and 11a are lifted to permit liquid from the supply pump entering at 19 to flow into a duct 21 and through a pipe 29 to raise the piston in the cylinder A, liquid above the piston being exhausted through a pipe 33, duct 25 and outlet 20a to the reservoir. When the piston is to move downward again the valves 11, 11a are closed and valves 15, 15a opened permitting pressure liquid to flow from an inlet 19a into the duct 25 and pipe 33, the bottom of the cylinder being exhausted through the pipe 29, duct 21 and an outlet 20. If a slow motion is required, a valve 36 may be introduced in one of the pipes, e.g. in the pipe 29 as shown. The valve is spring-loaded and has a bore 37 which can be engaged by an adjustable needle 38. Liquid flowing up the pipe 29 therefore has to pass through the throttled bore. Liquid being exhausted from the bottom of the cylinder forces the valve 36 downwards off its seating and has ample passage into the pipe 29 and duct 21.

Title: Aerial elements
IPC: G01D1/14
Filed: 1956-08-24
Abstract: 791,585. Aerials. SIHN, W. Aug. 24, 1956 [Aug. 25, 1955 ; Aug. 25, 1955; April 26, 1956], No. 25892/56. Class 40 (7). An aerial element of adjustable electrical length comprises a hollow outer member 2 and an adjustable inner member 3 slidable in a bore formed in an intermediate sleeve 4 of resilient material providing a watertight seal, the inner member being formed with annular grooves 6a, 6b, 6c, &c. and the sleeve having an inwardly directed bead 7 about one end of the bore (as shown more clearly in Fig. 2) which snaps into the grooves to hold the aerial adjusted at predetermined electrical lengths. The inner and outer members are isolated electrically by the intermediate sleeve, although where it is found to be desirable to provide electrical contact, an insulating member 5 which supports the inner end of member 3 may be replaced by a contact system, Fig. 7 (not shown). To facilitate the adjustment of an aerial array, particularly one comprising a large number of elements constructed according to the invention, the various sections of members 3 are coloured differently as indicated at 18a, 18b, 18c, &c. The sections are cut away intermediate the annular grooves to prevent the coloration from wearing off, Alternatively the sections may be numbered or incorporate a scale. Fine adjustment of the aerial element may be provided by means of a magnetic or dielectric device in association with member 3. In one construction, Fig. 3 (not shown), the member 3 carries a short sleeve which slides over the outer portion and is held in position by friction or a bead arranged to engage the annular grooves. In another construction, Fig. 4, (not shown), the magnetic or dielectric device takes the form of bell-shaped member adjustably mounted of member 3 with the mouth pointing back towards the inner member, the mouth being of sufficient diameter to pass freely over the outer member as the device is adjusted inwardly. Member 3 is coated with a material of a high dielectric constant. In yet another construction, Fig. 5 (not shown), a metal rod is provided as an adjustable core in member 3, and projects into member 2 to vary the coupling between members 2 and 3. Fig. 6 (not shown), illustrates a construction in which member 3 is constructed as a metal core with a magnetic or dielectric sheath. In connection with this embodiment, reference is made to the use of assembly comprising an inner member and intermediate sleeve for attachment to an existing aerial element to make it adjustable. Aerial elements constructed according to the invention are stated to be of use with dipole aerials, reflectors, directors, direction-finding aerials and television aerials.

Filed: 1967-06-06
Abstract: 1,190,432. Animal feeding. TELEDICTOR Ltd. 20 June, 1968 [6 June, 1967], No. 26004/67. Heading A1M. [Also in Division G4] In a system for controlling the feeding of cows each cow carries (either around its neck or implanted under its skin) a radio transmitter so that when a cow enters a combined feeding and milking stall it can be interrogated as to its identity and an appropriate amount of feed, which may depend upon its current and past milk output and its history of disease, can be dispensed. The radio unit carried by the cow may include batteries, but it is preferably powered by rectifying the r.f. interrogating signal. Each cow can be identified by a different combination of frequencies produced by oscillators in its radio transmitter. The central control unit stores a record of each cow's milk production and history of disease, which is updated whenever a cow is milked. In particular, a continuous examination of the milk produced is made and if mastitis is detected an indicating lamp above the milking stall may be energized to warn the cow man.

Abstract: 1465048 Forming sintered carbide containing alloys UNITED KINGDOM ATOMIC ENERGY AUTHORITY 31 May 1974 [1 June 1973] 26364/73 Heading C7D Sintered carbide containing alloys are produced by partly reducing a powder mixture of at least two metal oxides with a reducing agent other than elemental carbon and then adding sufficient carbon to the mixture to reduce the remaining oxide and form dispersed metal carbides when the mixture is pressed and sintered. Optionally the carbon may be included in the initial mixture as a powder or as methane or propane mixed with the reducing gas such as H 2 , Co, Co + H 2 , cracked NH 3  or producer gas. A mixture of oxides of Fe, W, Mo, Co, Cr and V 0À02-2 microns size is formed preferably by spray calcining of a solution of the metal salts at 500-1000‹C. After partial reduction on H2 at 700‹C, the powder is mixed with carbon e.g. 4À03 per cent under argon, milled in cyclohexane, compacted, heated in a vacuum of 0À05 torr at 1000‹C for reduction and then raised to 110-1260‹C for sintering sintered tool steels e.g. 83 Fe, 6 W, 5 Mo, 4 Cr, 2 V with dispersed carbides are produced.

Filed: 1972-06-06
Abstract: 1398310 Testing high voltage detectors IPA INTERNATIONALE PATENT-UND LIZENZ-ANSTALT 6 June 1972 [7 June 1971] 26366/72 Heading G1U [Also in Division H2]  A probe for detecting the presence of a high voltage on a power line includes, or can be associated with, a Piezo-electric crystal, which either by having a high-pressure applied to it or by being hit, causes a voltage commensurate with that whose presence is to be detected to be applied to the probe thereby to test that it is operating correctly. Two main arrangements are described. In the first, a Piezo-electric crystal 1, Fig. 3, is positioned at the end of a cylinder containing a piston M latched at the bottom of the cylinder by a lever O. Depression of a test button Q compresses a spring V, thereby loading the piston, and eventually when the button is fully depressed its end rocks a lever J to unlatch the piston which is then propelled rapidly, by the compressed spring V, against the crystal 1. The resulting potential appearing across the crystal is applied directly to one end 15b of a glow discharge tube 15 in the probe, and via the probe contact 18 and a spark gap 13 to the other end 15a of the glow discharge tube 15, so that an operator can be sure that the tube is working correctly. Release of the button allows a relatively weak return spring U to relatch the piston in its normal position as shown. In the second arrangement two crystals 1, 2, Fig.1, are used, so arranged that a sideways force by a member 10 displaces the crystals to a more in-line position thereby applying a considerable longitudinal pressure to the crystals. The potentials appearing across the two crystals are paralleled, outputs being taken from a centre connection 11, and an end connection 12. The two-crystal arrangement may also be used with impulsive force as shown in Fig.4a, in which in use the contact 18 of the probe is withdrawn against a spring 28 and let go, thereby causing a hammer 27 forceably to strike the end of the two crystals 1, 2. The probe shown in Fig.4a is of the kind in which light from the glow discharge tube 15 is conducted by a glass fibre 24 to a photo-cell 25, Fig.4b, whose output is amplified 31, 33, to energize a buzzer 30.
