Convention date, Feb. 20, 1931. [Class 122 (ii).] In a crankless motor for a jigging conveyer, the main valve is controlled by an auxiliary valve or cock which is positively actuated in both directions by the tappets associated with the main piston. The time of reversal may be affected by adjusting the tappets, or by a throttle valve in the passage between the auxiliary valve and the main valve. The auxiliary valve is locked against inadvertent displacement between its periods of actuation. The main valve i is opened at one end to fluid pressure, and is acted upon at the other end by a free piston i<2> of larger area, the right-hand side of which is alternately put to pressure and exhaust by a cock t actuated by tappets k, k<1> connected to the piston a and engaging arms u, t on the valve spindle. A throttle valve P is arranged in the auxiliary conduit r<1>. A throttle valve d in the valve chest in the passage leading to the forward side of the main piston, enables the pressure of the fluid in the space Z<2> to be reduced when the motor is unloaded or lightly loaded. The auxiliary valve is locked by loading one end with fluid-pressure.

Title: Automatic detection and correction of the base line drift of a variable electrical signal derived from a measuring instrument
IPC: C08F2/00
Filed: 1963-02-04
Abstract: 971,991. Electric selective signalling. SOC. NATIONALE DES PETROLES D'AQUITAINE. Feb. 4,1963 [Feb. 5, 1962; Jan. 25,1963], No. 4388/63. Heading G4H. A measuring device e.g. for gas chromotography produces a signal which deviates rapidly from and returns to a base amplitude and the apparatus of this invention is designed to hold the base voltage constant, e.g. at zero, by setting up an opposing voltage derived from a logical circuit controlled by the difference between the base amplitude and the opposing voltage. The input voltage X Fig. 1 from source S is opposed by voltage Z, the difference being applied to a zero detector which produces outputs A and B depending upon whether the voltage Z is greater or less than X. Pulses J from an oscillator OL are gated to the count up or count down inputs of counter CRD under the control of the signals A and B. The binary scale output from the counter is converted to an equivalent voltage Z by converter CDA. If a one-direction counter is used it is reset when change in the other direction is required or resetting may occur at regular intervals to allow a new balance voltage Z to be generated.

Title: Improvements in or relating to jib cranes and the like
IPC: B66C3/12
Filed: 1921-02-07
Abstract: 179,635. Watkins, W. H. Feb. 7, 1921. Jib cranes.-Relates to cranes in which luffing is effected by varying the length of a direct jibtie and the hoisting and luffing drums are geared together, and in luffing the hoisting-barrel pays out or winds in the load rope so that the load moves in a horizontal or other predetermined path. A direct jib-tie B, B<1> is pivoted to the crane frame at a point d chosen so that in raising the jib the change in the length d, g of the jib-tie, bears any approximately constant ratio to the vertical displacement of the jib head i. A construction for the point d is given in the Specification, a convenient direction being selected for the jib-tie at 'maximum outreach. The locus odc of the pivot d for varying ratios is drawn through the jib-foot c and in practice is the straight line cd produced: According to the invention the axis of the hoisting-barrel a or of a guide-pulley p, for the load rope is located at any convenient position on or near the locus odc,. the gearing between the hoisting and luffing drums having an appropriate constant speed ratio depending on the selected positions of the pivots d and a or p, and the crane being arranged in one of three ways, namely; (1) the jib-tie BB<1> and load rope f running from the jib-head centre i to separated points on the locus odc, (2) BB<1> and f running from a common centre g at any convenient point in the jib to separated points on the locus odc, as shown in Fig. 1, or (3) BB<1> and f running from a common centre such as g to coincident points on the locus odc. One arrangement of differential gear for the hoisting and luffing drums is shown in Fig. 6. The hoisting- motor drives a shaft s, pinion t<1>, two pairs of idler pinions u<1>, u<2>, pinion t<2>, and shaft S' connected to the winding-drum. The casing v carrying the idler pinions is geared by the wheel x to the luffing-drum, so that when the hoisting-motor and shaft s are stationary, the luffing-drum drives the hoisting-drum through the planet pinions u<1>, u<2>. In a modification, the hoisting-motor itself replaces the gearing t<1> - - t<2>, the pinion x being on the motor casing. In order to effect a slight raising of the load on luffing at both minimum and maximum outreach, the jib-tie B', Fig. 8, pivoted to the frame at d, is connected to a second point on the frame by a slotted link A. The link B<1> turns about d until the jib is at either extreme position, when the link A prevents further movement of B' and the jib-tie turns about C<1> or C<2> as fixed points on the frame. The weight of the jib may be balanced by a weight suspended by a tail-rope from the luffing drum or attached to a lever pivoted at the point d and moved by a sliding connection with the jib at a point corresponding to the point g, Fig. 1.

Filed: 1966-02-01
Abstract: 1,140,392. Digital measurement of dimension. PHILCO-FORD CORP. 1 Feb., 1966 [1 Feb., 1965], No. 4496/66. Heading G4H. In apparatus for measuring the dimension of an object a rotating scanning mirror 32 throws an image of the object on to a photocell 38 and at the same time throws the image of a scale 60 on to another photocell 66 to generate pulses which are gated to a counter while the image of the object crosses photocell 38. The object may be a strip of hot steel, radiation from which serves to activate the photocell Alternatively, the strip is cold and illuminated by a separate lamp. The scale is parallel with the strip and is illuminated by lamp 62. Photocell 66 generates pulses at an uneven rate as the mirror 32 rotates depending on the angles of the mirror but the number of pulse counted is linearly proportional to the width of the strip. To avoid errors due to displacement of the strip towards the mirror, which increases its apparent width, the edges may be scanned each by a separate mirror, or prisms mounted on arms so as to be positioned directly above the edges. The two images are combined and projected on to the rotating scanning mirror.

Title: Apparatus for guiding a tool head operating on a curved surface
Inventor: SLATER REGINALD
IPC: B23K7/00
Filed: 1956-02-14
Abstract: 810,608. Cutting and welding by fusion. WHESSOE Ltd. May 14, 1957 [Feb. 14, 1956], No. 4570/56. Class 83 (4). Apparatus for guiding a tool head, particularly a flame cutting or a welding head, along a path on the concave surface of a dished workpiece r, such as a steel plate, comprises a main radius arm b carrying the work-head a and pivotally supported by a universal bearing c, and a secondary radius arm e connected at d to the main arm and supported by a second universal bearing f adjustable longitudinally of the secondary radius arm so as to alter its effective length, and means k for swinging the arms about an axis g passing through the pivot centres of the two bearings. The apparatus described is for cutting dished plates to be sub. sequently welded together to form a sphere, and has a flame-cutting head with three nozzles for cutting a double bevelled edge as described in Specification 718,060. The universal bearings c, f may be of the gimbal or spherical type. Both are adjustable longitudinally of their arms and the latter are axially rotatable in their bearings. A cross-head m rotatably mounted on the main arm b is slidable transversely within a fork n carried by a tractor k movable along a horizontal path l at a variable speed by an endless chain driven by an electric motor. Thus movement of the tractor causes the arms to swing about the axis g which is adjusted to conform to the vertical axis of the sphere. Thus a plate supported at r will have a convex edge cut or alternatively a plate supported at q will have a concave edge cut. For cutting plate edges which are to lie on great circles of the sphere the secondary arm e is disconnected and the main arm b is caused to swing as a pendulum with its centre corresponding to the centre of the sphere. During cutting the plate is supported on a universally adjustable manipulator.

Title: Process for the catalytic desulphurisation of hydrocarbons
IPC: C10G45/08
Filed: 1951-02-26
Abstract: In a catalytic desulphurization of hydrocarbon mixtures containing alkenes by treatment with a gas containing hydrogen or a compound which yields or transfers hydrogen, the catalyst comprises alumina or bauxite impregnated with an oxide or sulphide of iron, nickel, or cobalt and an oxide or sulphide of chromium, molybdenum, or tungsten, the atomic ratio of the metals of the first group to the metals of the second group lying between 1:20 and 18:20 to which catalyst has been added a small quantity of a salt of an alkali metal.  Potassium chloride or nitrate may be used as the alkali metal salt, preferably in a ratio of potassium to the metals of the second group of 0.5:2.0 to 5:2.0.  Alumina, which has been activated by heating and treatment with 15 per cent hydrochloric acid, is impregnated with a solution containing cobalt nitrate, ammonium molybdate, and potassium nitrate, pulverized, graphite added, the catalyst made into tabloid form and heated in nitrogen.  The oxides may be converted into sulphides by the passage of untreated gasoline at 400 DEG C.  To suppress hydrogenation of the alkenes, the catalysts may be heated before use to 700 DEG -800 DEG C for 2-4 hours in air.  In examples gasoline fractions obtained by catalytic cracking are treated with hydrogen at 2-50 atmospheres or higher at a temperature of 400 DEG -450 DEG C. Tetra-ethyl lead may be added to the product to increase the octane number.

Title: Improvements in or relating to process of refining hydrocarbon distillates
Inventor: WEISEMANN GERT HANS
IPC: C10G27/08
Filed: 1952-02-21
Abstract: Mercaptons are removed from a sour hydrocarbon distillate without the formation of colour greater than about 1 N.P.A. therein by dispersing a copper compound in the distillate, intimately contacting the copper-containing distillate with about 1-15 per cent by volume of an aqueous solution of KOH having a concentration of about 50-60 per cent by weight so that the copper compound, which in amount ranges from about 0.004 to 0.1 per cent by weight of copper based on the KOH solution, forms a copper compound active as an oxidation catalyst by contact with the KOH solution, introducing an oxygen-containing gas into the mixture of catalyst-containing distillate and KOH solution, maintaining the temperature of contacting at about 80-125 DEG F. and separating spent KOH solution and associated reaction products from the treated distillate.  The spent KOH solution may be allowed to settle so that potassium cresylates separate out as a distinct layer which is then removed.  The spent KOH solution may then be regenerated by distillation and employed for the treatment of additional quantities of hydrocarbon distillate.  The oxygen-containing gas, which may be air or oxygen, may be employed in an amount which is about 1 1/2 -2\ba1/2 times that theoretically required for converting mercaptons present in the hydrocarbon distillate to disulphides.  Hydrocarbon distillates mentioned are naphtha, kerosene, heater oil and furnace oil, derived from the distillation of crude oil or from thermal or catalytic cracking processes.  In the case of air, the sweetening treatment may be carried out at 25-200 p.s.i.g., but the use of increased pressure is not ordinarily necessary in the case of oxygen.  The copper may be added in the form of an aqueous solution of a copper salt such as copper chloride, sulphate, nitrate or acetate so as to form a very fine dispersion in the hydrocarbon distillate, and preferably a water-in-oil emulsion.  When added in this way, the copper reacts with the KOH to form a blue compound, which is believed to be colloidal copper oxide, active as an oxidation catalyst.  The hydrocarbon distillate may be given a preliminary wash with an alkaline solution, e.g. sodium hydroxide or carbonate, to remove H2S, while the sweetened distillate may be passed through a fibrous or finely granular material such as glass wool, rock wool or sand, and then washed with water, in order to remove traces of KOH.  A small amount of a metal deactivator such as N. N1-disalicylidene -1, 2-diaminopropane may be added to the sweetened hydrocarbon distillate.  Specifications 728,057 and 745,631 are referred to.
