Abstract: PCT No. PCT/SE91/00144 Sec. 371 Date Oct. 22, 1992 Sec. 102(e) Date Oct. 22, 1992 PCT Filed Feb. 25, 1991 PCT Pub. No. W091/13176 PCT Pub. Date Sep. 5, 1991.A melt sample is taken in a sampling vessel which is in thermic equilibrium with the sample quantity prior to solidification commencing, the sampling vessel having been provided with at least one thermoelement and containing a determined and calibrated quantity of inoculating agent based on FeSi and sufficient to produce a maximum inoculating effect. The sample melt is allowed to solidify while temperature changes per unit of time are recorded. The difference between the minimum temperature in the undercooling phase, the maximum temperature in the eutectic reaction phase, and the eutectic equilibrium temperature Te, are determined. To the base melt are added thermodynamically stable particles of the type spinels, oxides or oxysulphides of elements such as magnesium, aluminium, potassium, zirconium, strontium, titanium and rare earth metals when the difference between eutectic equilibrium temperature Te and the minimum temperature in the undercooling phase exceeds 10 DEG  K. and when the difference between Te and the maximum temperature in the eutectic reaction phase exceeds 5 DEG  K. If found suitable, these method steps are repeated until those differences fall beneath 10 DEG  K. and 5 DEG  K., respectively.

Abstract: In the preparation of alkenyl succinic anhydride (ASA) from an olefinically unsaturated hydrocarbon and a maleic anhydride, additives are used in the preparation reaction in order to improve the yield of the product and to reduce side reactions. According to the present invention, quinone and hydroquinone derivatives as well as dialkyl sulfoxides and transition-metal acetylacetonate have such properties. The amounts to be added are approx. 0.01-2 mol % of the amount of maleic anhydride. The olefin is preferably a straight-chain  alpha -olefin or a straight-chain or branched internal olefin having a chain length of 6-20 carbon atoms. The olefin may also be a polyolefin, in which case the preferred molecular weight is 900-1500. The preparation process may be of the batch type or the semi-batch type, and the maleic anhydride and the additive may be added in several batches or as a continuous feed which may be even or variable. The ASA obtained by the process may be used in particular as an additive in foods, for hydroxy sizing of paper, or as a dispersing agent in lubricants.

Filed: 1944-07-14
Abstract: 569,124. Tea infusers. NOWAKOWSKI, M. K. July 14, 1944, No. 1246. [Class 129] An apparatus for infusing tea, or the like, comprises a steam-tight outer vessel A containing water, and an inner vessel B, on the bottom of which rests a wire basket F, containing tea. The basket has a 'handle J. The inner vessel is provided with a lid N and a pipe G for drawing off the tea. The outer vessel is heated and when the water boils, the pressure in A rises causing water to rise up a pipe C and flow down a pipe D and out through perforations in the bottom of D. This continues until the water level in A falls below the bottom of B and steam commences to escape from under the lid N. A tap H is then opened to reduce the pressure in A, the heat supply reduced and, after a short time, the basket F is removed after it has been agitated in the tea. A gauge level glass and a drain cock are fitted to the outer vessel A. An annular float may cover the surface of the tea to prevent any contact with the atmosphere. The outer vessel may be lagged to prevent heat loss. A small condenser may be fitted to a three-way cock which replaces H to prevent loss of water, the condenser also communicating with the bottom of A through a constriction in a pipe. Automatic operation using electromagnets and relays under the control of pressure gauges, may be used in larger sizes of infusers, and a signalling device incorporating coloured lamps included.

Valves 58, 62 interconnected by a link 68 and operable by a handle 66 are arranged so that when they are in the position shown and the fountain is open air is drawn over the printing cylinder 10 and through the fountain and discharged through the conduit 60. Upon turning the valves through 90 degrees, air is drawn through conduit 56, forced through the conduit 52 and the lower part of the fountain and discharged through the conduits 58, 54. The wall 24, Fig. 1, of the fountain is mounted on a pivot 26 carrying a cam 34 controlling a switch 38 in the circuit of the motor 44 so that the motor is started when the fountain is opened. An additional switch 46 is provided to permit operation of the motor when the fountain is closed.

In the apparatus shown, carriage 11 is moved by a lever (21) and the frame by cranks (23). When a plate reaches a work station, its clamp bar 2 activates a time relay which, when the required processing time has elapsed, supplies current to a solenoid 13 to cause a pawl 14 on a slide 12 to push a sleeve 9, slidably mounted in a bearing block 10, over a pin 8 extending from the clamp bar 2 so that the next cycle of the frame transports the bar together with its plate to the next work station.

Each strand of the sheath 4 lies with a long pitch relatively to the conductor 1 and may be circular or flat or comprise a number of conductors twisted together and insulated as a whole. Two or more sheaths 4 may be provided, one within another. In Fig. 2, a wave guide consists of a similar braided conducting sheath 6 supported by a tube 7 formed by winding a strip of " Polythene," a layer 8 of thinner strip " Polythene " preventing the sheath 6 sagging into gaps ; outside the sheath 6 is a layer 9 formed by winding a strip of oiled silk &c., or a covering 10 of rubber strip. The tube 7 may be supported at intervals by rings of insulating material spaced apart a quarter of the operating wave-length, or an odd multiple thereof. The guide, comprising a thin supporting tube of insulating material and the tubular conductor, may be enclosed in a flexible metallic tube. In another form, the insulating support comprises a number of short cylindrical or thimble-shaped elements fitting together and formed, as by complementary rounding of their edges, for ready flexing, the whole being held together by a covering such as a winding of insulating tape ; the longitudinal section of the elements is such as to give a substantially constant cross-sectional area, and the length of each element is preferably about a quarter of the wave-length to be propagated, or an odd multiple thereof.
