Abstract: 551,490. Differential gearing; driving propellers. BOWER, G. S., and DAY, B. I. Aug. 22, 1941, No. 10755. [Class 80 (ii)] Consists in gearing for driving two coaxial, e.g. propeller, shafts in opposite directions from two power units in such manner that the driving and reaction torques are all balanced. The rear ends of the shafts 10, 11, are formed as carriers 12, 13 for planet wheels 14, 15 which mesh with annuli 19, 20 and with sun wheels 17, 18 formed integrally with a sleeve 16 which is rotatable on the shaft 11. The annulus 19 has teeth 21 to mesh with a gear wheel driven by one crankshaft and the other annulus teeth 22 driven by the other crankshaft of the engine, the annuli being rotated in opposite directions. The sun wheels act as the reaction elements for their respective trains and balance the torque reactions of the two trains against one another. The gearing may be modified (1) by securing the sun wheels 17, 18 on the shafts 10, 11 and replacing the planet carriers by a common carrier carrying both sets of planets ; (2) by coupling the annuli 19, 20 together and re-arranging the sun wheels and planet carriers to act as the driving and driven members of the gearing.

Title: Improvements in or relating to apparatus for detecting and correcting departures from standard thickness or weight per unit length in textile slivers
Inventor: CATFORD MAURICE BRAUND
IPC: D01H5/40
Filed: 1957-04-03
Abstract: 889,969. Textile drafting mechanism. BRITISH JUTE TRADE RESEARCH ASSOCIATION. June 27, 1958 [April 3, 1957], No. 10811/57. Class 120(2) Mechanism for apparatus for detecting, and after an interval, correcting for departures from a standard in the thickness of a textile sliver undergoing drafting, comprises a rotatable frame around which are slidably mounted a number of rods, means for clamping those rods against longitudinal movement around the major portion of the periphery of the frame other than at a predetermined zone, and a feeler constrained to move in a direction parallel to the axes of the rods such that a surface contacts each rod in turn and follows the profile formed by the displacement of the rods. In Fig. 1, rods 4 are mounted in V-slots in a drum or pair of spaced discs, a large number of rods being employed to increase the sensitivity of the device. As the drum &c. rotates, the rods are moved along the slots to a uniform position determined by the setting of a zeroising cam 5. Their position is then adjusted by a cam 6 according to the thickness of sliver lying between detecting rollers and, after an interval, they correspondingly displace a feeler 8, whereby, through a parallel linkage and a sliding connection, oil relays are operated which control the drive to the drafting rollers. The mounting of the feeler is such that the length of the interval can be accurately adjusted. The feeler is of V-section, the angle of the V being not greater than twice that between the rod axis and the gradient of the rod-ends resulting from the probable maximum displacement of the rods. Between the cams 5 and 6, the rods are free to move in their slots, although they may be lightly retained by a guide or sheath; around the remainder of the drum circumference they are clamped by one of the following: a tensioned belt; an endless wire &c. twisted several times around the drum and a grooved pulley the diameter of the pulley, the position of the pulley above the drum, and the angle at which the axis of the pulley is skewed relatively to that of the drum being suitably chosen; a band surrounded by a roller chain constrained over part of its circumference by a clamp; the arrangement shown in Fig. 5. Here the drum consists of flanges 20 and a core 21 all of mild steel the latter being surrounded by an energizing-coil 24 which draws the rods into slots 23 in the flanges except where its effect is off-set when an air passage 25 in each slot registers with passages 28 in blocks 27 in communication with air under pressure.

Patent GB-109425-A (GB)
IPC: B41D3/00
Abstract: 109,425. Printing Machinery Co., (Wood, H. A. W.). Sept. 7, 1916. Stereotype. - In apparatus for casting curved stereotype plates of the kind in which a segmental back is moved into and out of casting position by a power-operated toggle, the toggle is connected to and operated by a second toggle connected to the source of power, the three pivots of each of the toggles being in substantial alinement when the back is in casting position. As shown, the back B is moved radially towards and away from the core C by links 109 pivoted by studs 108 to a yoke 110 pivoted at 112 to the framing A, the links 109 and yoke 110 forming a toggle. A second toggle comprising links 103, 102 pivoted together at 107 is pivoted at its ends to one of the studs 108 and to one end of a lever 101 which carries a roller engaging a grooved cam 22 on a rotating shaft. A toe-piece 104 on the link 103 normally engages a stop 105 on the link 102 ta keep the pivots 108, 107, 106 in substantial alinement, so that normally the links 102, 103 act as a rigid member, which, by the oscillations of the lever 101 alternately break and make the toggle 109, 110 thereby withdrawing and advancing the back B once for each plate cast. To permit of the back being turned down into an horizontal position to change the matrix or for other purposes, a trip cam 121<a> is moved into the path. of a projection 120 on the link 102, thereby breaking the toggle 102, 103 and thus preventing the making of the toggle 109, 110, until by the removal of the cam 121<a> from the path of the projection 120, the toggle 102, 103 is again made. The cam 121<a>, which is held by a spring in both its operative and inoperative positions, is secured to a shaft 122 which is rocked when desired by a slidable rod 125 acting through an arm 123 on the shaft 122. When the toggle 102, 103 is broken, the back can be turned down manually by means of a handle attached to it, and is controlled by toothed segments 126 pivoted to the sides of the back and engaging racks 127 on the framing A. Smooth rims 126<a> on the segments also engage tracks 50<a> adjacent to the racks to support the weight of the back. During the radial movement of the back away from the core C, the back is guided and supported by rollers 128, mounted on studs 128<a> on the back, and running in short guides 129 on the framing, relative movement of the segments 126 and the back being permitted to an extent controlled by toggles 290 pivoted at their ends respectively to the segments and to the studs 128<a>. When the rollers 128 leave the guides 129, the toggles 290 are straight and prevent further relative movement of the segments and back. The toggles 290 are broken during the return of the back to vertical position by the engagement of projections 291 on the toggles with projections 292 on the guides 129.

IPC: C21C7/00
Filed: 1923-04-27
Abstract: 223,622. Borchers, W., and Stimson, R. W. April 27, 1923. Alloys; roasting.-Alloys containing iron and one or more of the metals chromium, molybdenum and uranium in any proportions, with or without other metals, are obtained bv the reduction of a material consisting of a highly oxidized artificial solid solution containing one or more of the above metals. The material, which is basic and has a melting point below 1600‹ C., may be made by roasting under freely oxidizing conditions an intimate mixture containing minerals or compounds of one or more of the metals and one or more basic oxides such as lime or magnesia. The basic oxide is used in such proportion as not only to form chromates &c., but also to give the product a basic character, and preferably also in sufficient excess to ensure that acid oxides formed during the reduction will be retained in the slag without requiring the presence of further flux. The materials to be roasted are dried and coarsely crushed, and are preferably bound bv means of a solution of an alkali or alkaline earth carbonate or hydrate. Burnt lime may be slaked with a solution of the binding-agent to a thin paste into which chrome iron ore may be kneaded, the mass being dried, coarsely crushed, and roasted. The required alloys are produced by reducing the material by means of reducing agents, preferably containing silicon, for example an iron-chromium-silicon alloy; or an additional metal such as nickel may be obtained by using an iron-nickel-silicon alloy. A mixture of the reducible material and the reducing agent may be treated in a suitable electric or other furnace, on a hearth, or on a layer of slag, or on the surface of molten metal or alloy, fluxes being added towards the end of the reaction if required. Specification 223,617 is referred to.
