Patent GB-132111-A (GB)
IPC: G05G17/00
Abstract: 132,111. Williams, E. Oct. 31, 1918. Controlling variable-speed gearing and other mechanism. A mechanical relay or controlling-device comprises a cam loose: on a power-driven shaft b and pressed by a spring e against a disk c secured to the shaft. The cam f is kept from being driven by friction from the disk c by a lever j having a projection: i engaging one of a number of stops h on the cam. When the lever is disengaged by snugs Ic on a disk l, the cam f turns and actuates a lever g. The lever gcontrols a variablespeed gear or moves anything as nequired. A shaft asupporting the disk l is turned by power or by hand. The stops h may be staggered, the lever j being displaced laterally by the snugs k. The cam f may be replaced by an eccentric or Geneva stop, and may be geared to a more slowly moving part carrying the stops h.

Abstract: 1429598 Removing coatings A B DICK CO 26 March 1974 [29 March 1973] 13408/74 Heading B2E A coating, such as a photoconductive layer of selenium, is separated from a metal substrate to which it is bonded, said coating and substrate having different thermal coefficients of expansion, by cooling the coated substrate to a temperature well below 0‹C, wetting the coated surface with a liquid which freezes above the temperature to which the coated substrate has been cooled, to form a layer of frozen liquid on the coated surface, and applying heat to at least one surface of the coated substrate to cause the frozen liquid with the coating adhered there to separate from the metal substrate. The liquid is usually water, and the coated substrate, e.g. photolithographic aluminium drum with a photoconductive layer of selenium, may be cooled by immersion in liquid nitrogen. Subsequent heating may be by spraying either the frozen liquid layer (i.e. ice) or the opposite surface of the substrate, with warm water, when the ice layer having the selenium adhered thereto separates from the substrate. The selenium may then be recovered from the melted ice.

A diamond shaped structural component folded along its longer diagonal has its edges so formed that a plurality of these components may be assembled edge to edge with at least one of the components in a reverse fold position relative to others. The edges of the component 30 shown in Fig. 1 are comprised by four quadrilateral, non-parallel, planar faces and two parallel isosceles triangular planar faces 41 at obtuse corners of the diamond, the concave side of the diamond being larger than the convex side. The edges of the components shown in Fig. 21 are formed by framing members 44 having formations 44a each presenting inclined faces 45 and a cylindrical face 46 symmetrically disposed about a plane normal to the joint edge. The centre line 47 of the cylindrical face is equipped between the planes of the panel stems 43. Adjacent components in identical or reversed relative fold positions (see also Figs. 19, 20, 22, not shown), abut along the centre line of the cylindrical face and are locked together and sealed by clamping components 48-54, which cooperate with the faces 45. The configuration describes and illustrates several forms of structure assembled from components according to the invention. (For Figures see next page)

Title: Improvements relating to mechanism for the electrical actuation of engine controls and like controlled elements
IPC: G05D3/12
Filed: 1943-08-19
Abstract: 568,758. Electric control systems. EVERSHED & VIGNOLES, Ltd., and WALKER, D. D. Aug. 19, 1943, No. 13539. [Class 40 (i)] [Also in Group XXIV] In a system in which an electric power motor drives a control element such as the throttle of an aero-engine or the steering gear of ship through an electromagnetic coupling, in the event of the failure of the electric supply, the coupling is disengaged and an actuating member is released to move the control element into a predetermined position, which in the case of an aero-engine may correspond to the cruising speed of the aircraft. The power motor may be controlled by a follow-up mechanism as described in Specification 564,224. As shown, a crank C on the motor shaft M carries a pivoted coupling bar B which is held in a notch n in the end of the throttle lever l as long as an electromagnet E is energized, while a pair of pivoted sectors A1, A2 coupled by a torsion spring R are held by an electromagnet L. When the current fails, the bar B is disengaged by a spring S and the sectors are released to move towards each other. The sectors are provided with pins P1, P2 extending in both directions for engaging the throttle lever t and a stop member N, so that the throttle lever t is moved to the same angular position as the stop member N, which may be adjusted by means of a worm W. When the current is restored, the bar B is attracted, but is arrested by the rim of the sector A2, for example. As the attendant moves the motor control member to an extreme position, the bar engages the step K1 of the other sector A1 and pushes it to the position where it is held by the magnet L. The motor is then reversed and the sector A2 is pushed in the same way to its latching position. The motor is again reversed and the bar B rides up the inclined surface of the lever t and snaps into the notch n, which it has been unable to enter hitherto on account of the sloping edges H1, H2 of the sectors Al, A2.

Abstract: 1,172,246. Cooling reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 21 March, 1967 [29 March, 1966], No. 13731/66. Addition to 1,085,633. Heading G6C. In a liquid metal impurity content monitor, of the " plugging meter" type, the known relationship between temperature and impurity solubility is employed. In a liquid sodium monitor 10, the impurity is deposited at the orifice 12. The resultant partial plugging causes a reduction in the rate of flow through pipe 13. Due to the re-entrant length L, the same amount of heat is transferred from the flow in pipe 14 to that in pipe 13, the temperature of the liquid in pipe 13 rises, unplugging occurs and the flow increases thus reducing the temperature. Temperature fluctuation occurs about the impurity saturation temperature, indicated on thermocouple 12a.

Title: Process for the production of alloyed steels
IPC: C21C7/00
Filed: 1951-06-11
Abstract: A process for the production of steel alloys comprises adding to a steel melt material such as manganese, chromium, tungsten and/or their ferrous alloys and/or suitably alloyed scrap. blowing oxygen into the melt, reducing the steel and the refining or final slag by suitable reducing agents and completing deoxidation of the steel and slag by addition of aluminium in such quantity that no substantial excess of aluminium is present over that quantity necessary for deoxidation.  Before addition of alloying materials unwanted quantities of elements such as carbon or phosphorus are removed by a preliminary refining, e.g. by blowing in oxygen, and the slag is removed.  Refining slag without reducing agents may be added before the main oxygen blowing treatment and, where the melt was made in an electric furnace the oxygen blowing may take place in a different vessel such as a ladle or converter.  The production of an alloy steel having the analysis C 0.59 per cent., Si 0.27 per cent., Mn 17.2 per cent., P 0.4 per cent., S 0.005 per cent., Cr 38 per cent., and Ni 0.1 per cent. is referred to.
