Title: Improvements in and relating to screw propeller blades and the like
IPC: B63H1/12
Filed: 1932-05-11
Abstract: 404,631. Screw propellers. ROSS, C. H. A. F. L., 1619, Massachusetts Avenue, Washington, U.S.A. May 11, 1932, No. 13564. [Class 114.] In the manufacture of a screw propeller blade the determination of points on the driving surfaces thereof is obtained from a projection of the blade shape on a plane at right angles to the axis of rotation and both the helix angle of a circular section and the leading and trailing points are obtained from a diagram having the propeller axis as a vertical axis of reference along which are plotted distances representing angular displacement from a radially-disposed base-like whilst a horizontal axis represents radial distances. In addition the radial distances are plotted so that the resulting sections do not overlap. Fig. 1 represents the projection of a blade upon a plane at right angles to the propeller axis and from an arbitrary base-line radial to the axis circular arcs are marked with degrees showing the distances of the leading and trailing edges from the base-line. In setting out the helix angle, a method indicated in Fig. 5 is adopted, wherein the base-line represents three times the radius, the starting point A is fixed at a distance R from the origin and the vertical distance is the pitch divided by #. Other vertical distances are plotted proportionately thereto to represent angles whereby the leading and trailing points, which for example are 17‹ and 74‹ at radius 4<11>, of each section is determined. The driving face of sections at radii 2-10 as obtained from Fig. 5 are shown in Fig. 2 imposed on one diagram. Having thus determined the sections of the driving face, the blade is machined along circular arcs to correspond. A construction is also given for use with curved rear faces whereby the centre is determined in relation to the straight driving face, and the machining tool is set in accordance therewith. Specifications 376,674 and 381,751, [both in Group XXIII], are referred to.

Title: Improvements in or relating to self-stabilising jib-cranes
IPC: B66C23/10
Filed: 1933-05-12
Abstract: 402,344. Jib cranes. WATKINS, W. H., 95, Elthorne Avenue, Hanwell, London. May 12, 1933, No. 13905. [Classes 78 (ii) and 78 (iv).] A counterweight a is moved outwards by the pull in the hoisting rope and also by outward luffing of the jib, and the hoisting gear is arranged to run idly if the load to be raised from the ground exceeds a predetermined weight. As shown, the counterweight a, Fig. 1, is on an arm b pivoted at c to a lever d rocked by the jib. The arm b is also connected by links i, lever g, and links k to cranks j, which are geared to the planet-carrier l, Fig. 2, of an epicylic gear between the power shaft o and the hoisting drum. On attempting to lift a load, the planet-carrier l at first rotates without transmitting the drive and the arm b is moved outwards about the pivot c until the counterweight a supports the reaction of the planetcarrier and enables it to transmit the drive, but if the load exceeds the safe maximum for the crane, the planet-carrier will continue its movement without transmitting the drive. If the members b, d, g, i form a parallel-motion linkage, the load-balancing movement of the counterweight is not affected by the luffing, but the links d, i or the lever arms may be unequal. In a modification, Fig. 3, the lever g is pivoted at a point above the jib-pivot, and the fulcrum c for the counterweight a slides in guides in the jib-tail d under the control of a radius link i<1> which may be equal and parallel to the link i. As shown in Fig. 4, the epicyclic drive is omitted and the hoisting rope n is reeved over a sheave v on the jib-axis and a sheave w on the short arm of the counterweight lever b pivoted on the jib-tail, so that the hoisting-gear at first swings the counterweight a outwards until the sheave w is held against further movement. In a modification, Fig. 5 (not shown), the hoisting rope passes from the sheave v to the jib-head and a load-block, back to the sheave wand is anchored on the jib-tail.

Patent GB-560641-A (GB)
Title: Improvements in or relating to electrical means for the detection of gas in liquids
IPC: G01N27/22
Filed: 1942-10-07
Abstract: 560,641. Determining physical qualities of materials; capacitance measurements; condensers. NAPIER & SON, Ltd., D., and CLARKE, M. E. Oct. 7, 1942, No. 14072. [Class 37] Apparatus for detecting gas in liquids, particularly for detecting the amount of air contained in lubricating oil, consists of a condenser comprising a series of plates in a chamber through which the liquid is caused to flow, the plates which are spaced apart lying parallel to each other and to the direction of flow, a meter which will indicate variations in the capacitance of the condenser, and means whereby an alternating current is passed through the condenser and meter. The oil under test is arranged to flow constantly through a sampling condenser shown in Fig. 5. The condenser plates M are mounted in a rectangular casting L provided with tubular members K, K1 which are connected to inlet and outlet pipes for the oil. The plates M are mounted on two bases, one insulated and alive and the other earthed to the casing. Connection to the plates is made by a terminal N, while N1 is a pressure tapping point for measuring the pressure of the oil. The plates may be constructed of aluminium or aluminium alloy and may be anodised. The measuring circuit is shown in Fig. 4. A dynatron oscillator D5 has an oscillatory circuit D6 in its anode circuit and feeds the grid of a valve E4, the output of which passes through resistances G2, G3. Automatic volume control is applied by means of a copper oxide rectifier K supplied from a potentiometer S1. As the output increases the rectified portion becomes more negative and increases the negative bias, which reduces the amplification and hence the output.. A delay is provided by biassing the rectifier positive to a value slightly below the output voltage required. This prevents rectification occurring until the output voltage exceeds the value of this positive bias and any excess of voltage is rectified and passed on as negative bias to the controlled valve. The oil sampling condenser is arranged in a bridge circuit of which the resistances G2, G3 form two arms, the fourth arm being a variable condenser H. In the diagonal of the bridge is a rectifier J and D.C. instrument A2. The condenser H is adjusted to balance the bridge when the sampling condenser is in air, giving zero deflection. A standard condenser C4, filled with de-aerated oil, is then substituted and the high-frequency voltage applied to the bridge is adjusted by means of the potentiometer S1 until full scale deflection is obtained. A condenser C3 in parallel with the condenser C4 serves for temperature correction. Connection to the condenser constituting the aeration element is either at the terminals C2a, C2b, or C2c.
Patent GB-141170-A (GB)
Abstract: 141,170. Pfenninger, H. March 13, 1919. Generating by electricity and by reduction of pressure of heated water.-In an electric steamgenerating plant, water is heated in two stages, being first superheated in a vessel A, Fig. 1, and then evaporated at a lower pressure in a separate heat-storing vessel B which has coiled tubes f or radiator-like elements, and electric heating-elements embedded in a heat-storage mass. The vessel A has electric heaters a and a safety valve b. The supply of superheated water is controlled by a valve g. The pressure in the vessel B may be determined by a loaded valve i in the outlet, A number of steam-tubes f are arranged in vertical planes in the vessel B, the water inlet being either at the top or bottom, and the steam outlet in the reverse position. Electric heating-elements are removably inserted in metal tubes l, Fig. 2, which are mounted in perforated walls m, and arranged in planes parallel with the heating coils. The walls m are formed in sections, the structure being built up by securing the lower sections in position, inserting the steam-coils and the lower heating elements, and ramming in from the top the heat-storing material consisting of sand or pieces of stone or rock, preferably steatite, with a binder such as cement, lime or gypsum, the finer material being placed around the heating- elements. The upper sections and elements are then placed in position and more material rammed in. The heat stored in the vessel B, for instance at night, may be sufficient to evaporate the water, or heat may also be supplied during evaporation. Thermometers may be inserted in the vessel B, and a gauge may be provided.

Title: Upgrading of copper concentrates from flotation
IPC: B03D1/06
Filed: 1965-04-02
Abstract: Copper sulphide concentrate is recovered from an ore containing sulphides of copper and of iron by floating the ore to obtain a rougher concentrate containing a major proportion of the recoverable copper sulphide, separating the concentrate into sands and slimes, treating the sands in an alkaline state with a soluble cyanide and subjecting the treated sands to a flotation operation whereby the copper sulphide content of the sands is in large part recovered in the resulting concentrate and flotation of the iron sulphide content is in large part inhibited.  Essentially, the ore is ground to about minus 65 mesh and the ground ore is the subject to a rougher flotation operation.  The rougher float tails are passed through a scavenger float, the tails from this scavenger float being discarded and the concentrate usually, but not necessarily, being reground and returned to the rougher float.  The rougher float concentrate is separated in a hydrocyclone into sands and slimes.  The sands are treated with a soluble cyanide in the presence of lime or with crude calcium cyanide and, preferably after regrinding, are floated to produce a finished concentrate and tails.  The tails either directly or after a scavenger float may be discarded, or directly or after the scavenger float recycled to the sand-slime separation step or fed back to the rougher float.  The separated slimes may be added directly to the sand flotation step, or they may be sent to a smelter with the finished sand concentrate, or they may be floated separately the concentrate being sent to the smelter and the tails being discarded directly or after a scavenger float.  The slimes scavenger float concentrate is recycled, preferably to the rougher float. Examples of modifications of the process are given and proportions of cyanide and line are specified.  The preferred soluble cyanide is crude calcium cyanide, but sodium cyanide, hydrocyanic acid, and other alkali or alkaline earth cyanides or organic cyanides, e.g. lactonitrile, may be used.

Abstract: 1493497 Continuous polyamide manufacture BASF AG 7 April 1975 [8 April 1974] 14132/75 Heading C3A Polyamides are prepared continuously from aqueous solution of single or mixed nylon salts or mixtures thereof with a lactam or aminoacid by conveying the solution through several reaction zones under polyamide forming conditions. In the first zone the reactants are heated to 200 to 300 C. at a pressure above the corresponding saturation vapour pressure of water sufficient to prevent the formation of a vapour phase until the polycondensation conversion is at least 80%. In the second zone the pressure is released adiabatically to between 3 and 20 atmospheres gauge so as to reach a temperature below 215 C. In the third zone comprising a heat exchanger with parallel elements the polycondensation mixture is then heated to 220 to 330 C. in less than 5 minutes with evaporation of the bulk of the water at the pressure level to which it has been reduced in the second zone or at a lower level. The condensation is then completed in one or more further stages. In specific Examples (1) and (3) nylon 66 salt with 1% excess hexamethylene diamine, and (2) the salt of adipic acid and 2,2-di-(4-aminocyclohexyl)-propane are polycondensed.
