Title: Grain refinement process for copper-bismuth alloys
Inventor: KNAPTON ARTHUR GEORGE
IPC: H01H1/025
Filed: 1965-06-30
Abstract: A method of preparing copper-bismuth alloy with a refined grain structure comprises casting an ingot of copper-bismuth alloy, containing 0.05-1% bismuth by weight, and thereafter extruding the alloy at 300 DEG -950 DEG C.  Before extrusion, the ingot is machined to produce a billet which may be encased in a copper can, the ends of which are sealed with welded-in copper plugs.  The can may be evacuated before being sealed.  Extrusion may be through a die of circular or, for producing strip material, rectangular cross-section, after which the copper sheathing is removed by machining. Extrusion ratios of 4:1 and grain sizes of 0.1 mm. diameter and 0.2-0.3 mm. are referred to.  In an example extruded at 500 DEG C., the alloy was then annealed at 800 DEG C. for one hour.

Title: An improved form of vacuum closing machine for tinplate containers and the like
IPC: B67B3/24
Filed: 1952-11-05
Abstract: 723,075. Closuring containers in vacuo. CLARKE, D. Feb. 4, 1954 [Nov. 5, 1952], No. 27801/52. Class 125 (2). Relates to machines for closuring containers in vacuo in which a sleeve 8 is raised around a container 4 carried on a platform 6 until it abuts a gasket on the underside of the sealing head 1, suction is applied by a valve 20 to the enclosed space around the container and the rest 6 is raised to introduce the container top into the sealing head. According to the invention, the sleeve is open-bottomed, the bottom being closed in the raised position by cooperation with a fixed closure member 7. This allows liquid to drain from the sleeve into a catch tray 14 when the former is lowered. As shown, the sleeve has a restricted lower end which fits the closure member 7. Alternatively, the sleeve may be of uniform diameter and the closure member may be expanded into engagement with the lower end thereof by suction means. As shown the sleeve is carried by a member 9 fixed to a cylinder 21 slidable on a hollow, fixed piston rod 22, the space above the piston being connected by the rod and by a pipe 25 and three-way valve 26 to the suction valve 20. In operation, a container is pushed by hand on to the platform 6 and rotates a lever 27 to rotate a rod 31 which removes a catch 30 from member 9. This allows spring 29 to raise the sleeve 8 and then valve 20 vacuumizes the container space. The container is then raised, sealed and lowered and valve 20 operates to vent the container space and apply suction to pipe 25. This draws down the cylinder 21 and sleeve 8 which is retained lowered bv the catch 30 when the sealed container is removed. In modifications the cylinder 21 may be fixed and the sleeve 8 carried on the piston rod or the sleeve may be raised by a system of levers.

Patent GB-211442-A (GB)
IPC: B41F7/12
Filed: 1923-11-08
Abstract: 211,442. Fallot, A. Feb. 14, 1923, [Convention date]. Rotary offset machines.-A rotary offset machine for printing in colours in various ways consists of an offset cylinder e fitted with two offset surfaces d, i which coact with printing-plates f, k of printing-cylinders g, l of the same size as cylinder e and arranged with their axes in the same plane. The arrangement is such that the plate f commences to print on the offset surface d at the same time that the plate k prints on the offset surface i. An impression cylinder b of half the diameter of cylinder e may be fed with sheets from a feedboard a, or with sheets cut by cutters z from a web b<1>. The parts m, o of the plate cylinders are below the printing level, but can be fitted with plates if desired, and from these extra plates direct or offset impressions can be obtained. When these are not used a two-colour impression can be obtained by passing a sheet around cylinder b and taking an offset impression from the surface d, and then transferring the sheet printed face downwards to grippers h to the surface i, which prints a second impression when it passes the cylinder b. For forming a perfected impression an offset surface is fitted to cylinder b, and it receives a double offset impression from the surface d which is printed on the opposite side of the sheet to the impression obtained from the surface i. Tripping-arrangements.-The cylinders b, g, l are mounted in eccentric bearings which are capable of being operated simultaneously by a threearmed lever u when it is desired to trip the cylinders. The centres of the eccentric bearings of the cylinders g, l are disposed at different sides of the common plane passing through the axes of these cylinders and the offset cylinder e. The Specification as open to inspection under Sect. 91 (3) (a) comprises also other arrangements of the machine for multi-colour printing. By fitting printing plates to the parts m, or o, a sheet can be printed with two double offset impressions on one side and a direct offset impression on the other side. Or the plate m can superpose a direct impression on a sheet which receives an offset impression from the surface i, and a double offset impression from the cylinder b. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,137,214. Feed for ruminants. COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION. 20 June, 1967 [21 June, 1966; 1 May, 1967], No. 28395/67. Heading A2B. A feed supplement for ruminants comprises a particulate proteinaceous material of plant, animal, or synthetic origin, the particles having been chemically modified and/or coated to form at least on the surface a substance or complex which is relatively stable in solutions having a pH greater than 5, so as to protect the material from microbal attack in the rumen, but being unstable in acid solutions have a pH below 4.0, so that the material remains susceptible to breakdown and digestion within the abomasum and small intestine. Thus for example the exposed proteinaceous material may form part of a polymeric proteinaceous complex, for example by treating the particles with an aldehyde such as formaldehyde. Alternatively, the particles may be coated with a polymer or co-polymer of a basic vinyl or acrylic monomer.

Title: Improvements in controlling means for internal combustion engines for aircraft

Abstract: 383,378. Controlling flow of lubricant. ROWLEDGE, A. J., Ellerslie, Trowels Lane, RUBBRA, A. A., Red Roofs, Carlton Road, and FARMER, G. H., Sunnydale, Shamrock Street, all in Derby. Oct. 14, 1931, No. 28537. [Class 12 (iii).] In altitude controls for aircraft engines in which the throttle valve is actuated both manually and by an aneroid - controlled relay preventing excessive charging of the engine, means are provided for limiting the movement of the relay device so that it may be overridden by the manual control for obtaining extra power at ground levels, and the supply of lubricating-oil to the engine cylinders may be adjusted simultaneously with the throttle. Fig. 1 shows an aneroid capsule a subject to blower - outlet pressure by a connection a<4> and connected to a valve b<1>, which controls communication between pipes d, d<1> leading to the blower outlet and inlet respectively and passages e<2>, e<3> leading to opposite sides of the relay piston f. This piston is connected to one end of a floating lever g, which is connected intermediately to the manual control h<1>, and at its other end to the throttle g<3>. The movement of the relay piston in the direction for closing the throttle is limited by an adjustable stop i. Normally, the manual control is moved only in the upper part of the segment h<2>, but, when extra power is required at ground levels, the manual control is moved through a gate slot or the like to the bottom of the sector, as shown in Fig. 1, thereby opening the throttle farther than that permitted by the relay, the piston of which is held against the stop i. The gate slot serves to give the pilot warning of the necessity of returning the manual control to its normal position, but a further indication is given by the action of the relay in moving the throttle past the fully-open position as the aircraft ascends, thereby reducing the power. The middle of the lever g may also be connected to a three-armed lever connected to the ignition-timing lever, to the fuel-metering device of the carburetter, and to a cock controlling the flow of lubricant to the cylinders. Specification 356,619, [Group XXVII], is referred to.

Title: Seismic corrections

IPC: G01V1/36
Filed: 1965-07-06
Abstract: 1,101,797. Seismic signal processing. MOBIL OIL CO. 6 July, 1965, No. 28567/65. Heading H4D. In a method for determining the static and normal moveout corrections for a set of seismic traces obtained from a plurality of geophones spaced in a spread between first and second shot-points, the static corrections for the traces associated with the geophones at either end of the spread are determined by up-hole measurements, the total time correction (static plus moveout and dip) for each trace is determined by cross-correlating each trace separately with a portion of a reference trace obtained from a geophone at the centre of the spread, the total time corrections of the end traces are combined with their static corrections to give their dip and normal moveout corrections which are then extrapolated to give the dip and normal moveout corrections for each of the intermediate traces, and the dip and normal moveout corrections of the intermediate traces are then subtracted from their total time corrections to give their static corrections. The dip of a particular subsurface formation may be estimated by time-shifting the cross-correlation function for each trace by an amount equal to the normal movement plus the static correction for that trace, further shifting each function by increments of time corresponding to the dip between adjacent geophone traces for each of a plurality of assumed dip lines, and summing the shifted functions to obtain a sum for each assumed dip line. The dip line associated with the maximum sum indicates the most probable dip. In finding the total time correction for each trace, the first four traces may be composited and correlated against the fifth trace to obtain the total time correction for the fifth trace; the corrected fifth trace is added to the composite and the first trace is dropped, and the new composite is correlated against the sixth trace to obtain the correction for the sixth trace; and so on. A mathematical treatment of the corrections and a criterion for the selection of the portion of the reference trace, are given. The calculations may be made by an analogue or digital computer, and details of the routing of instructions and data through a typical digital computer together with a FORTRAN programme, are given. For digital computation, seismic data in the form of a magnetic tape recording of the traces is transposed on to punched cards which are read into the computer.
