Filed: 1965-06-10
Abstract: 1,105,084. Two-part couplings. R. A. PATTON. 10 June, 1965 [17 June, 1964], No. 24595/65. Heading H2E. A miniaturized electrical plug or socket connector consists of two concentric tubular bodies e.g. 26 and 30, the outer surface of each of which has grooves to accommodate resilient blade contacts 36 and 38, the outer surfaces of which lie flush with the outer surfaces of the bodies. The contacts are formed with the same cross-section as the grooves and may be stuck in position, or held by the coaxial sleeve arrangement, an outer sleeve 34 being provided which also forms an hermatic seal. The ends of the contacts are of undulating shape to mate with complementary shapes on the engaging contacts and the bodies are relieved to permit inward contact movement, or the contacts relieved to permit outward movement, during engagement. A centring pin may be provided along the hollow axis of the plug. A keying arrangement may facilitate correct rotational engagement, or the plug and socket may be relatively rotatable to provide a multiplicity of engagement positions. In a further arrangement, Fig. 12 (not shown), auxiliary contacts 78 provided in each connector in an outer ring are much narrower than the main contacts. In this case, the plug and socket are first mated with the main contacts out of alignment and then relatively rotated until the auxiliary contacts engage one another, at which point the main contacts will almost completely overlap. A relay, energized through the auxiliary contacts, then closes the main contact circuits.

Title: Crown block for oil well derrick
IPC: E21B19/02
Filed: 1960-07-15
Abstract: 898,184. Pulley blocks; oil well derricks. MOORE CORPORATION, LEE C. July 15, 1960 [Jan. 29, 1960], No. 24712/60. Classes 78 (4) and 78 (5). A crown block for an oil well derrick comprises a frame 12, Fig. 5, one end 16 of which is reckoned as the front, which frame supports a row of parallel sheaves 20 rotatably mounted on a common axis, behind which row is a pair of sheaves 24, 27 placed edge-to-edge and rotatable on parallel axes extending from front to back of the frame. In use the frame 12 is mounted for lateral movement atop the derrick 1, Fig. 1, and a line 8 from the winding drum 9 passes over one of the sheaves 24 or 27 and thence to the travelling block 7 which is connected by a plurality of loops 6 of the line to the row of sheaves 20. For drilling the central well B of a set of three spaced wells A, B, C, the line stringing arrangement is as shown in Fig. 8 ; A or C may be drilled without moving the derrick by appropriate traverse of the crown block and, in order to prevent an oblique pull on the drum 9, the line 8 is either transferred to sheave 27 (for well A) or re-strung in the opposite sense on sheave 24 (for well C). Guide sheaves 31 and 32 serve to prevent the line 8 from slipping from sheave 24 or 27 when the derrick is canted from the vertical. This situation arises if the supporting member 5 (Fig. 1) is displaced about its pivotal connection with the derrick to allow the use of the apparatus as a crane. If this usage is not required, the sheaves 31 and 32 are not necessary and the axis 19 of the sheaves 20 may then be parallel to the axes 23, 26 of the sheaves 24, 27.

Abstract: 468,588. Screw propellers. FAIREY, C. R. Sept. 12, 1936, No. 24932. Addition to 457,823. [Class 114] An airscrew blade of the kind referred to in the parent Specification is modified in that the pistons used for moving the leading portion of the blade are placed at an angle to the longitudinal axis of the blade whereby centrifugal force thereon provides for an automatic opening and closing of the gap between the two parts. The adjustable leading edge 11 is carried by rods having at the inner ends pistons 12-15 moving in cylinders 16-19. The two centre pistons are connected by a pipe line with a chamber 22 in the hub 23, there being within the chamber a spring 25 acting on a piston 24 so that as centrifugal force increases with increasing speed upon the pistons 13-14, these are enabled to move inward, the piston 24 moving to compress the spring 25. Admission of fluid to the cylinders is by way of passages having non-return valves which tend to move off their seats under centrifugal force, thus permitting the escape of fluid when the revolutions of the blade exceed a predetermined number.

Abstract: 1,006,647. Paper folding machines. ASHTON PRESS MFG. CO. Ltd. June 17, 1964 [June 17, 1963], No. 25135/64. Heading B6H. A machine for zig-zag folding of a travelling web of paper 9, Fig. 1, at any of a plurality of predetermined intervals of length comprises a pair of drums 4 mounted on a frame 1 said drums being driven at the same peripheral speed as the web of paper by gears 8. Each drum comprises a plurality of radial recesses 19 (Fig. 3, not shown) each receiving a folder blade 17 for movement between an operative position projecting from said drum into an aligned recess of the other drum to impart a fold to the web and an inoperative position in which the blade is contained wholly within the recess. The blades 17 are spaced at equal peripheral distances of e.g. ¢ inch which can be multiplied by whole numbers to give said predetermined length. Thus to give an 8¢-inch interval between folds the 17th blades on alternate drums will be actuated in a stagger manner. The blades are held in the inoperative position by springs 21, Fig- 2, and displaced into the operative position by compressed air entering air inlet members 10 abutting faces 11 of drums 4 via ducts 14, 12, 13 and an arcuate recess 16 in the inner face of each member 10. The air is selectively admitted to the blades by a ball valve 28 in a duct 26 when a pusher member 31 is depressed by a laterally extending pin 32 of a special control link 33 of chains 6 engaging sprockets 7, whose teeth correspond in number to the number of recesses 19 and blades 17. The control link 33 opens the valve as soon as it engages the sprocket 7 and keeps it open as duct 25 passes recess 16 to permit the projection of a blade 17 and the making of a fold. The chains 6 carrying the control link 33 at predetermined intervals are interchangeable for different fold spacings.

Title: Process for denitrosing oleum
Inventor: WOLF FRIEDRICH
IPC: C01B17/94
Filed: 1960-07-19
Abstract: Oleum containing at least one nitrogen-oxygen compound is denitrosed by adding to it a derivative of ammonia, the derivative being urea, amidosulphonic acid, hydrazine sulphate, hydroxyl ammonium sulphate, or acetamide.  The derivatives are usually used in excess of the amounts of nitrogen-oxygen compounds in the oleum, although hydrazine sulphate is effective when not in excess, but only below a concentration of 50% oleum.  Urea is efficient at a temperature of 50 DEG C., and in relatively small amounts.  The oleum is heated to the required temperature with agitation, and then mixed with a small amount of the ammonia derivative to be used, either in powder form or in the form of a solution in concentrated sulphuric acid.  The reaction is usually complete after 60-100 minutes.  The initial concentration of the nitrogen-oxygen compounds before denitrosation may be determined so that the quantity of ammonia derivative can be varied accordingly.  30% oleum may be distilled after denitrosation to produce 100% oleum, or may be mixed with 100% oleum to produce 65% oleum.

Abstract: 518,555. Yarns and threads. CARBIDE & CARBON CHEMICALS CORPORATION. Aug. 27, 1938, No. 25194. Convention date, Sept. 15, 1937. Drawings to Specification. [Class 120 (iii)] [Also in Group IV] Artificial fibres, filaments, threads, or yarns are made from vinyl resin obtained by conjoint polymerisation of a vinyl halide and a vinyl ester of an aliphatic acid and containing a predominant amount of vinyl halide, and having an average molecular weight of at least 15,000. 'The resinous component may contain 80-95 per cent of vinyl halide. A solution or dispersion of the resin is formed into filaments by extrusion. The filaments may be twisted or doubled and subjected to stretching. Stretching may be effected in presence of solvents or with heating. The stretched materials have high true elasticity, and. high dry and wet strength. They are flexible, thermoplastic, and non-inflammable. Polymers of vinyl chloride and vinyl acetate may be used. Stretching of the yarn may be effected in cold or hot water containing a wetting agent. After stretching, the yarn may be set by ageing under tension or by immersing the yarn in water. The yarn may then be subjected to flexing operations. When staple fibres are to be obtained the stretching may be omitted. The staple fibres may be used in conjunction with wool or cotton fibres. Partial fusion on heating of the vinyl resin permits stiffening of mixed yarns to be obtained. The yarns may be knitted woven or braided: They may be used in making filtering fabrics, fishing nets and lines, acid- and alkali-resistant clothing, protective pipe coverings, shower curtains, or electrical insulations. Articles having wire or rubber filaments with a core of the polyvinyl compound filaments may be obtained. Specifications 426,744, 437,773, [both in Group IV], and 475,635, [Group III], are referred to.

Abstract: 1322996 Resistors; capacitors WESTERN ELECTRIC CO Inc 19 April 1971 [30 March 1970] 25385/71 Headings HIS and H1M The resistance of a thin film device e.g. a resistor or capacitor is trimmed to within predetermined limits of a predetermined value by placing the device, 10, in a tank containing an electrolyte for example a 0À1% citric acid solution when resistor 10 and cathode 13 are of tantulum, and connecting the device to a computer controlled relay 26 which connects the device either to a constant current source 22 for the purpose of anodizing the film, or to a resistance measuring circuit, 32, coupled to the computer controlling the relay. The anodization is carried out by a reiterative process (Fig. 4, not shown). The steps involve first measuring the film resistance and then calculating the length of time the films must be further anodized to increase its resistance to the desired value. The film is then anodized for a fraction r of the calculated time after which the resistance is again measured. The process is then repeated using successively greater values of r, subject to r # 1, until the resistance measurement corresponds to a value within the prescribed limits of the required value. The Specification contains a detailed account of the mathematical calculations performed by the computer indicating how the anodization time is calculated from the resistance measurements. Specification 1,112,521 is referred to.
