Title: Dithiocarbamate derivatives
Filed: 1957-01-11
Abstract: The invention comprises the compound bis-isopropoxycarbonyl ethylene - bis - dithiocarbamate and its preparation from isopropyl chloroformate and a salt of ethylene-bis-dithiocarbamic acid, preferably an alkali metal salt in aqueous solution below 25 DEG  C. An example is given of the process.  The corresponding methyl, ethyl, n-propyl, n-butyl and 2-octyl esters are referred to, and also the 1 : 2-propylene homologues.ALSO:A fungicidal composition for plants comprises bis-isopropoxycarbonyl ethylene-bis-dithiocarbamate in solution or mixed with an inert finely-divided solid carrier.  The latter must not be basic, and can be a neutral or acid clay or talc, with or without a dispersing or wetting agent.  A specific composition contains clay, magnesium carbonate, a condensed naphthalene-formaldehyde sodium sulphonate and a t-octyl-phenoxy-polyethoxyethanol.  This can be applied dry or dispersed in water.  For application in solution acetone and dimethylformamide are suitable solvents, and wetting and sticking agents can be added before or after dilution with water.  The compositions can be mixed with soil and/or other non-basic fungicides or insecticides.  They can be applied to any part of the plants, to harvested seeds, or to the soil.

Title: Improvements in the manufacture of base-exchange materials
IPC: B01J39/24
Filed: 1935-01-14
Abstract: Ion-exchanging substances suitable for softening water are obtained by treating coal or anthracite with a current of gaseous sulphur trioxide, or a mixture containing it, at a temperature not exceeding 250 DEG  C., and preferably not exceeding 150 DEG  C., the reaction being stopped before there is any appreciable formation of free carbon.  The treatment may be carried out in a water-cooled rotary drum through which the coal and gas are passed in opposite directions.  The product is washed and dried at a temperature of 30 to 40 DEG  C.  The coal may be caused to react with as much as ten times its weight of the sulphur trioxide and the weight of the coal may be increased by as much as 60 per cent. Specifications 450,574 and 450,575, [Group I], are referred to.ALSO:Ion-exchanging substances suitable for softening water are obtained by treating coal or anthracite with a current of gaseous sulphur trioxide, or a mixture containing it, at a temperature not exceeding 250 DEG  C., and preferably not exceeding 150 DEG  C., the reaction being stopped before there is any appreciable formation of free carbon.

Title: Apparatus for Interpreting Stability for the use of Shipmasters.
Inventor: GRAHAM THOMAS
IPC: B63B9/00
Filed: 1917-01-26
Abstract: 112,822. Graham, T. Jan. 26, 1917 Calculating - apparatus for investigating ships' stability problems gives (1) the metacentric height or G.M., (2) a measure of the righting-arm or lever of transverse stability when the vessel is heeled over through any angle, and (3) the position of the water-line relative to the freeboard deck edge as the vessel is heeled over, and comprises (a) an apparatus for indicating the righting - arms and the water-line, and (b) a device for use therewith from which the metacentric height may be obtained. The apparatus (a) consists of a wood or metal lamina T representing the midship section of the vessel pivoted at a point f corresponding to the mean position of the centre of curvature of the curve of flotation, the pivot being secured to a standard X carrying a pointer p moving over a scale to show the angle of heel. On the vertical centre line of the lamina is a scale of feet graduated from the keel upwards over which moves a pointer t mounted in a slot s. To the point of the part t is pivoted a rod n indicating the resultant of gravity when the pointer is set to the metacentric height. One of a series of plates M representing the metacentric evolute for different posiplacements is secured by pins m and held in position by a blade-spring J. A plumb-line W passing over the edge of the plate represents the resultant line of the buoyancy and the distance between these two verticals read on a scale of feet Z carried by the part n shows the magnitude of the righting-arm. The water-line is shown by a thread S passing across the front of the device and secured to a rod Q adjustably mounted in a. slot-in the standard. Metaccentric calculators ; logarithmic calculators. -The device (b) comprises a chart bearing two linear scales A, B showing the draught in feet and the dead weight in tons and a logarithmic scale C representing height in feet of the centres of gravity of the cargo above the keel. Co-operating with the scale C are two similar scales E, F, representing respectively dead weight in tons and the moment about the keel, so arranged that the moment in foot tons is obtained by the intersection therewith of a straight edge P placed at the required positions on the scales C, E. Two curves D, K are marked on the chart, the first being the displacement curve set off logarithmically to any unit, and the second, the locus of heights of transverse metacentres above the keel in feet. In operation, a logarithmic scale S, graduated to the same scale as the curve D showing the heights of centres of gravity in feet and the total moment in foot-tons, is placed against the dead weight on the scale B with the graduation representing the total moment opposite the curve D. The height of the centre of gravity of the ship above the keel is read off on the line x, x of the scale C, and this height, when deducted from the height of the transverse metacentre obtained from the curve K, gives a measure of the G.M. in feet.

Abstract: 1385151 Dolls &c MATTEL INC 10 Jan 1973 [10 March 1972] 1429/73 Heading A6S [Also in Division G5] In a toy, e.g. a doll, incorporating a spring driven gramophone wound by a draw string, a string engaging element is provided for preventing play back after the spring motor is wound until a further action e.g. kissing of the doll, is effected. Draw string 14 is connected to string drum 32 on gramophone 10 via pulley wheel 40 mounted at an end of a plunger member 54. During the winding process the outward pull on the string moves plunger 54 downwardly against the action of spring 52 until a hook part 46 of the plunger engages under a catch 48 on frame 38. In this latched position of the plunger a pawl 64 wedges the string into one of the recesses 58 formed in the wheel 40 thus preventing windback of the string on to its drum and hence playback of the record 28. On the doll being kissed arm 50 releases hook 46 and the plunger moves upwardly under the action of the spring thereby releasing the string so that playback commences.

Abstract: 1,146,241. Locking fastener. LAMSON & SESSIONS CO. 11 Jan., 1967 [16 Feb., 1966], No. 1447/67. Heading F2H. A fastener, e.g. a lock-nut, has a locking thread convolution which differs from the basic form for mating with a co-operating standard thread 24 so as to interfere with the mating thread to provide a locking action, the thread angle being the same as for the basic form but the width of the metal convolution between the flanks 30, 32 being greater than the maximum width for a standard thread of the same basic form so as to provide uniform interference with a standard mating thread along the flanks 30, 32 of the locking thread convolution. A recess 35 is provided between adjacent threads which is axially larger than the space defined by the triangle between adjacent threads and which extends radially from the position of the crest 40, 36 of the standard mating thread. The recess 35 is designed to accommodate metal swaged due to the thread interference to prevent seizure of the threads. The locking convolutions are formed in a resilient collar portion 22 of a nut such that the collar expands outwardly due to the thread interference but exerts a force inwards on the threaded stem due to its resiliency to effect a further locking action.
