Title: Governor operated fuel control systems
Inventor: CATFORD ADRIAN LESLIE
IPC: F02D1/00
Filed: 1958-04-03
Abstract: 907,112. Governors. NAPIER & SON Ltd., D. March 25, 1959 [April 3, 1958], No. 10932/58. Class 57. A fuel control system of a fuel injection engine comprises a governor driven at a speed proportional to the engine speed, a governor input member 14 arranged to vary the datum setting of the governor, a governor output member 13 controlled by the governor and connected to a fuel control member 11, and a differential device sensitive to movement of both the input and output members and arranged to prevent movement of the input member beyond a position corresponding to a certain maximum rate of fuel delivery to the engine, which position is determined by the instantaneous positions of the input and output members. The governor is of the centrifugal spring-loaded type and actuates a sleeve, the latter transmitting its motion to the shaft 13 which in turn via links 16, 17, 18 rotates a shaft 19 coupled by links 20, 21 to the fuel lever 11, thereby varying the supply of fuel. The movement of the shaft 19, in addition to actuating the fuel lever 11, also moves a floating lever 22, 26 which, at one end, is connected to a link 25 fixed to the shaft and, at its other end, is provided with a roller 27 which is urged into contact with a pivoted cam 28 by a spring 33, the movement of the lever 22, 26 being transmitted via a link 36 to a lever 37 which in turn operates one or other of switches 42, 43, depending upon whether the engine speed rises or falls, so as to energize a reversing electric motor 44. Rotation of the motor causes a shaft 45, connected to a lever 32, to rotate the shaft 14 and thereby react the governor loading to the new speed datum; the cam 38 is repositioned simultaneously by a link 30 connected to the lever 32 so as to allow the lever 22, 26 to return to its neutral position and thereby release the appropriate switch. The speed datum can be manually set by a lever 15 secured to the shaft 14, a limited range of movement of the latter being permitted by a lost-motion device 46, 47.

Title: Improvements in, or relating to, Hinged Cover Supports for Cabinets, Boxes and the like.
Inventor: BARNETT CECIL JOHN
IPC: A45C13/34
Filed: 1918-07-04
Abstract: 128,424. Barnett, C. J. July 4, 1918. Stays.-Relates to supports for the covers of gramophone and other cabinets, tool and other boxes, piano tops, hinged seats such as theatre seats, and like hinged members. The Figures show the invention applied to a gramophone cabinet. The support shown in Figs. 1 and 2 comprises two links B, E, jointed to fold at D and pivoted respectively to the lid at C and the side of the cabinet at F. A spring H, disposed as shown, tends to maintain the links in a straight line. A pin K on an extension of the link E entering a notch in the other link forms a stop. The spring H is at a minimum tension when the lid is open, but it acts with a greater turning effort than when the lid is closed as shown in Fig. 1. The cover may bo retained closed by arranging the spring so that it arrives in a straight line over and with the link E, before the lid actually closes. Fig. 4 shows a modification which supports the lid in any position. An extra spring L, which is stronger than the spring H. is employed to balance the weight of the lid. When the lid is fully open the spring L is slack. Means may be provided outside the cabinet for operating the above-described support without touching the lid, such as a handle R operating through a shaft P and link N. The support may be controlled by a weight applied to an extension of the link E. Instead of the stop K, the end of the link may contact with the bottom of the cabinet to form a stop. Means may be provided for adjusting the position of the fixed end of the spring L. If desired a pneumatic, or liquid checking-device may be used in connexion with the supporting-device.

Title: Improvements relating to the recovery of uranium by ion-exchange
Inventor: ARDEN THOMAS VICTOR
IPC: C22B60/02
Filed: 1953-04-23
Abstract: In the recovery of uranium in the form of a complex anion from an uranium containing solution also containing cobalti-cyanide by treatment of the solution with an anionexchange material in salt form, the solution is first passed in contact with a separate mass of anion-exchange material also in salt form which constitutes a trap or filter for the cobalticyanide.  The main mass of anion-exchange material is subsequently eluted to recover the uranium in solution and regenerate the anionexchanger, whilst the cobalti-cyanide trap material is removed when it permits cobalticyanide to pass to the main anion-exchange mass.  The process is particularly applicable to the recovery of uranium from uranyl sulphate solutions obtained for example from an ore containing both gold and uranium which has been first treated with cyanide to extract the gold thereby forming cobalti-cyanides from the cobalt normally present, and subsequently subjected to an oxidizing acid treatment to extract the uranium as uranyl sulphate and convert the complex cyanides to cobalti-cyanides. The cobalti-cyanide trap may be a strongly basic material which may also take up uranium initially but which will permit such uranium to be displaced by cobalti-cyanide.  When the trap material is exhausted it may be eluted to recover any uranium it may contain and thereafter may be treated by ignition for the recovery of cobalt.  Alternatively a weakly basic resin for example a polystyrene bead resin containing ethylamine groups, may be used in which case the cobalti-cyanide taken up may be removed by successive treatments with caustic soda and sulphuric acid thereby regenerating the trap material. Specifications 626,882 and 783,591 are referred to.

Title: Improvements in the sequestration of ferric iron in caustic alkali solution
Inventor: SMITH ROBERT LEWIS
IPC: C01D1/32
Filed: 1954-04-21
Abstract: Ferric iron is sequestered in a caustic alkali solution by the addition thereto of a compound which combines an aminocarboxylic acid and an aminoethanol structure in the same molecule.  The effective pH range is dependent on the balance of ethanol to carboxylic acid groups in the molecule.  These groups may have a nitrogen atom in common as in hydroxyethylamino diacetic acid or dihydroxyethylamino acetic acid, or they may be attached wholly or in part to different nitrogen atoms as in the ethylene diamine derivatives, namely hydroxyethyl ethylene diamine triacetic acid, both di (hydroxyethyl) ethylene diamine diacetic acids and tri-(hydroxyethyl) ethylene diamine acetic acid.  Similar derivatives of diethylene triamine, triethylene tetramine and tetraethylene pentamine may also be employed.  The effective pH range may be extended in the acid direction by the simultaneous addition of aminocarboxylic acids such as aminotriacetic acid, or ethylene diamine tetracetic acid; the pH may be extended in the alkali direction by the addition of aminoethanols such as triethanolamine, or tetra-(hydroxyethyl) ethylene diamine. Specification 692,449 is referred to.
