Title: Method of making light weight concrete of high strength
IPC: C04B18/14
Filed: 1933-07-08
Abstract: Slag for use as an aggregate in Portland cement concretes is granulated by the simultaneous disintegration and chilling of a stream of molten slag preferably by providing an iron hull against which the molten slag is thrown either by a blast of compressed air, or by revolving steel vanes operating in the path of the slag stream. A spray of water or steam is also preferably included in the air blast or a spray of water is directed on the steel vanes. Cold water is also preferably sprayed on the iron hull.  This treatment is stated to produce hard porous particles having considerable mechanical strength.ALSO:A light porous concrete is produced by mechanically disintegrating a stream of molten blast furnace slag into drops, chilling the drops to produce a granulate consisting of hard porous particles, crushing and grading the particles into determinate and desired sizes, mixing with Portland cement and water and allowing to set.  The granulation of the slag is effected preferably by providing an iron hull against which the molten slag is thrown either by a blast of compressed air, or by revolving steel vanes operating in the path of the slag stream, a spray of water is also preferably included in the air blast, or directed on the steel vanes.  The particles are graded so that no particles of more than half an inch diameter are present.  Any particles over this size are crushed.  In addition, part of the aggregate which passes the 8 mesh sieve is ground to cement fineness and then put back with the unground residue.  The final aggregate so obtained is re-apportioned in any desired manner before being mixed with Portland cement and water.  If desired, a proportion of hydrated lime may be added to the mix of slag, cement and water.  In an example, a concrete mix suitable for floor filling is produced by mixing 1 part of Portland cement, 1 part ground slag, 2 parts of slag passing the 8 mesh sieve, 2 parts of slag passing the 4 mesh but retained on the 8 mesh sieve and 3 parts of slag passing the 2 mesh but returned on the 4 mesh sieve.  This mix requires 2 lbs. of water per lb. of Portland cement, and the product has a density of about 70 lbs. per cubic foot.

Title: PROCESS FOR THE MANUFACTURE OF FILAMENTS AND FIBRES FROM POLY-beta-AMIDES
IPC: D01F6/60
Filed: 1970-04-23
Abstract: 1282345 Spinning polyamides FARBWERKE HOECHST AG 23 April 1970 [23 April 1969] 19533/70 Heading B5B Filaments are manufactured from polymers of #-lactams of the formula which are used as homopolymers, copolymers with other compounds of this formula or as mixtures of polymers derived from #-lactams of this formula, wherein R, R<SP>1</SP> and R<SP>11</SP> each represents a substituted or unsubstituted alkyl radical containing 1 to 18 carbon atoms, aryl, aralkyl or cycloalkyl radical and in which R<SP>1</SP> and R<SP>11</SP> may also each represent hydrogen. The polymer is dissolved in formic acid and spun through a spinneret into an atmosphere of a dry inert gas at a temperature of from 70‹ to 300‹ C. The polymer is present in the spinning solution to an extent of 10 to 40%, preferably 15 to 32% by weight, as outside these limits the solution is generally too fluid or too viscous to be spun easily. The preferred copolymer is one containing between 50 and 80% by weight of 4-methyl azetidine-2-one, the remainder 3,4 dimethylazetidine-2-one. The formic acid is preferably in a concentration of 85 or 98%; the latter being used for polymers of relatively low molecular weight. The filtered and degassed spinning solution is conveyed to the spinneret by means of a spinning pump which maintains the conveying capacity constant. The spinning head, pump and spinneret, as well as the feed lines and drain pipes may be heated and cooled. The spinning head is placed on top of an air shaft provided with jacket heating into which hot air or another inert gas such as nitrogen is blown parallel to the direction of movement of the filaments. This hot gas removes most of the solvent, which may be recovered if required. The filaments are drawn off at a rate of 100 to 500 m./min., preferably 150 to 350m./min., stretched to at least three time sits original length on a heatable stretching device of conventional type such as godet rollers and subsequently wound up at a rate of from 500-2000 m./min. with an optional washing step between drawing- off and stretching.  Other spinning conditions, such as the temperature, amount and rate of air blown into the shaft, the conveying capacity, injection rate of the spinning solution, number of apertures in the spinneret and aperture diameter depend on the shaft dimensions and may be varied within wide limits; the limiting factor being that the filaments should contain no more than 5% formic acid when leaving the spinning shaft. In general, however, the spinning shaft is heated in the range of from 50 to 250‹ C., preferably 100‹ to 200‹ C., and the inert gas is at a temperature between 70‹ and 300‹ C., preferably 100‹ to 270‹ C. The spur filaments may be prepared with a slightly alkaline solution, such as a solution of triethanolamine, which reacts with small amounts of acid and, preferably, yields a liquid product. Filaments are obtained which have a tensile strength of up to 9À0 g./dtex. and which can be processed into sewing thread able to withstand temperatures over 300‹ C.

The arrangement is self-checking in that the bugs 23, 24 should be superimposed one upon the other as the aircraft touches down at the airfield. The radar altimeter signal 30, in analogue form, is subtracted in a differential servo-amplifier 34 from the output of a follow-up potentiometer 35, amplifier 34 output controlling a servo -motor 36 which moves the potentiometer slide 35a and the stator 37a, 37c of a synchro control transformer 37. An analogue input 43 from the barometric altitude servo driving the pointer 14 passes to a rotor 46 of the transformer 37 so that the output from the rotor 37b thereof is affected by both barometric and radar altitudes. The rotor 37b signal controls, via a servo-amplifier 38, a servo motor 39 which moves the rotor 37b and the bug 24. The altimeter is otherwise generally as described in Specification 1409647, with a radar altitude digital display 16, a digital indicator 15 showing barometric altitude in thousands and hundreds of feet, and the scale on dial (12) has marking 0-9 indicating hundreds of feet. The barometric setting of the pressure altitude mechanism, as set by a knob 17, is shown on counters 18, 19 in inches of mercury and millibars respectively. Minimum decision height (MDH) is set by a knob 20, and a comparison circuit 31 fed with the radar altitude signal 30 actuates a visual and/or audible alarm if actual height over the ground is less than or equal to the MDH.
