Title: Diisocyanate modified polyesters
IPC: C08G18/42
Filed: 1955-07-29
Abstract: Diisocyanate modified polyesters are made by reacting m-xylylene diisocyanate, p-xylylene diisocyanate or a 5-alkyl-1,3-xylylene diisocyanate in which the alkyl group contains 1 to 8 carbon atoms, or a mixture thereof, with a polyester derived from a glycol and an organic dibasic acid.  The preferred 5-alkyl-1,3-xylylene diisocyanate is 5-tertiary butyl-1,3-xylylene diisocyanate. Specified dibasic acids contain three or more carbon atoms, e.g. malonic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, suberic acid, azelaic acid and sebacic acid which acids may be replaced in part by unsaturated acids, e.g. fumaric acid, maleic acid; by aromatic acids, e.g. phthalic acid and terephthalic acid; and by substituted or hydroxy acids, e.g. tartaric acid and thiobutyric acid.  Specified glycols are ethylene glycol, 1,2-propylene glycol, 1,3-propylene glycol, methyl-hexane - 1,6 - diol, 1,6 - hexane diol, 1,4 - butane diol, diethylene glycol, triethylene glycol, butylene glycol, pentamethylene glycol and hexamethylene glycol.  In the examples, an ester prepared from adipic acid, ethylene glycol and propylene glycol is freed from moisture and reacted with: (1) m-xylylene diisocyanate; (3) p-xylylene diisocyanate; and (4) 5-t.-butyl-1,3-xylylene diisocyanate to yield rubbery products which can be stored before processing and cured by reaction with water, glycols, amino alcohols and diamines.

Title: Improvements relating to aircraft
IPC: B64C27/02
Filed: 1934-07-27
Abstract: 442,016. Aircraft with rotary-wing systems. KAY GYROPLANES, Ltd., KAY, D., and DYER, J. W., 18, Atholl Crescent, Edinburgh. July 27, 1934, No. 22022. [Class 4] In aircraft of the kind in which the lift is derived wholly or partly from an overhead rotary wing system the rotor is mounted on a single turnable member so as to be capable of tilting in the lateral and fore-and-aft directions, the arrangement being such that turning of the turnable member causes the rotor supporting member to tilt laterally whilst permitting movement of the rotor-supporting member in the fore-and-aft direction about the axis of the turnable member. In the form described the turnable member is of the type described in Specification 285,213, [Class 114], and comprises a hinge pin or zed - crank barrel 6, Fig. 4, keyed to an axle 7 journalled in rotor supporting bracket 10. Axle 7 is arranged substantially at right angles to the fore-and-aft plane of symmetry, C-C, Fig. 2, of the aircraft, the axis A-A of barrel 6, in its neutral position, being substantially horizontal and inclined to the axis B-B of axle 7. Barrel 6 is formed with two coaxial bearing parts 4, 5 upon which are journalled downwardly depending cheeks 2, 3 of rotor-supporting mast 1, Fig. 1. With this arrangement mast 1 may be tilted in a generally fore - and - aft direction about the axis A-A of barrel 6, i.e. along a line inclined to the centre line of the aircraft whereby the unbalancing of the lift due to the variation in the angles of incidence of any laterally extending blades will be compensated by the shifting of the rotor centre with respect to the c.g. of the aircraft. Turning of axle 7, and hence of barrel 6, causes the rotor mast 1 (provided it is held against fore-and-aft movement) to tilt laterally owing to the resultant tilting in the vertical plane of the axis of the zed - crank barrel. Control of fore-andaft tilting is effected by a pull-and-push rod 18 linked at its upper end to a pivot block 14 mounted on a pin 13 connecting the rear ends of side plates 11, 12 respectively secured to side cheeks 2, 3 of mast 1. Block 14 is located by distance pieces 15, 16. The lower end of rod 18 is universally jointed to a screwed spindle 22 adapted to be driven axially by a nut 25 keyed to a cable drum 28. Rotation of axle 7 may be effected by manual or power means under the control of the pilot. Mast 1 is, as shown, mounted slightly behind the zedcrank member but may be mounted vertically above the same. Reference is made to the rotor starting gear and blade incidence control mechanism which are partly shown in Figs. 1 and 2 and which are described in Specifications 442,014 and 442,015 respectively.

Title: Improvements in or relating to process of purifying glycerine containing ionizable impurities
IPC: B01J39/02
Filed: 1946-07-24
Abstract: Crude glycerine solutions containing at least 1000 parts per million of ionisable impurities are purified by passing them through a number of pairs of ion exchangers, the first member of each pair being a cation-active or hydrogen zeolite exchanger and the second an anion exchanger.  The process is continued while the influent to the final anion exchanger contains less than about 600 parts per million of anions and 50 parts per million of cations, or while the pH of the influent to the final anion exchanger is at least 3 and/or that of the effluent from such exchanger is at least 4.  It is stated that the use of more than four pairs of ion exchangers is not economical. The purified glycerine may be finally distilled in a relatively simple still and a product of high quality obtained.  The process is preferably employed with relatively dilute solutions such as 5 to 20 per cent glycerine, but may also be used with glycerine containing only 1 or 2 per cent of water.  In such cases the final distillation step may be eliminated.  The anion and cation active materials are regenerated after use in the conventional manner by treatment with dilute solutions of alkali or acid solutions respectively and subsequent washing with water.  As cation-active materials may be used a resinous material prepared by reacting furfurylacetone sulphonate with furfural (see U.S.A. Specification 2,372,233), aldehyde condensation products of a -furyl substituted organic sulphonates (see U.S.A. Specification 2,373,152), polyhydric phenolaldehyde condensation products such as catechol-tannin-formaldehyde, aromatic sulphonic acid-formaldehyde condensation products (see U.S.A. Specification 2,204,539), or the carbonaceous zeolites, i.e. sulphated or sulphonated carbonaceous materials such as coal, peat, or lignite. As anion-active materials may be used resins prepared from guanidine, guanyl urea, and biguanide as prepared according to Specification 561,896, [Group IV], or the aldehyde condensation products of m-phenylene diamine, biguanide, guanyl urea, substituted guanidines such as methyl guanidine, substituted biguanidines such as phenyl biguanide, polyethylene polyamines, &c.
Patent GB-951026-A (GB)
Title: The manufacture of sulphonamides
IPC: C07D239/69
Filed: 1962-06-07
Abstract: The invention comprises (a) a process for the preparation of sulphonamides of the formula: <FORM:0951026/C2/1> wherein R1 is hydrogen or a C1-6 alkyl or alkoxy substituent and R2 is a C1-6 alkyl group, and salts thereof, by hydrogenating a thio compound of the formula: <FORM:0951026/C2/2> wherein X is an amino group or a group convertible into amine by hydrolysis or reduction, and, where necessary, converting the group X into amino and, if desired, converting the resulting sulphonamides into their salts, and (b) as new compounds the intermediate 2-alkylthio -4-benzenesulphonamidopyrimidines of the formula (II) wherein R1 is an alkyl or alkoxy group of 1-6 carbon atoms.  The intermediate compounds of the formula (II) are made by reacting the appropriate 4-amino -2- alkylthio -6- alkoxypyrimidine with a benzenesulphonyl halide containing a group convertible to amino by reduction - hydrolysis (e.g. nitro, acetylamino or alkoxy-carbonylamino) in the para-position and, if desired, converting the product to the corresponding p-amino derivative.  2-Methylthio -4- amino -6- methoxy-pyrimidine and the corresponding 5-methyl-, -ethyl-and -methoxysubstituted derivatives used as starting materials, are made by methylating the appropriate 6-hydroxy-pyrimidine by means of a quaternary phenyl trimethylammonium salt.  2-Methylthio -4- amino -6- hydroxy-pyrimidines bearing a methyl, ethyl or methoxy substituent in the 5-position are made by condensing an a -methyl-, -ethyl- or -methoxy-cyanoacetic ester with thiourea and treating the resulting 5-substituted -2- mercapto -4- amino -6- hydroxy-pyrimidine with dimethyl sulphate or methyl iodide.  Specification 886,693 is referred to.

Patent GB-1393021-A (GB)
Title: Circular knitting machines and articles knitted thereby
IPC: D04B1/14
Filed: 1972-05-11
Abstract: 1393021 Knitting machines and knitted fabrics V LUCHI 11 May 1972 [14 May 1971] 22102/72 Headings D1C and D1K A knitted fabric comprises an inlaid warp thread TV which forms loops around the needle loops MI in certain wales of the fabric.  As shown in Fig. 7 the fabric is formed on a cylinder and dial machine the yarn MI being knitted by the cylinder needles and the yarn LI by the dial needles. The yarn TV is fed below the latches of the cylinder needles by yarn guides (described later) which are located in spaced positions in the tricks of the machine dial. A laid in weft yarn TO is provided and this is fed below the dial needles and behind the cylinder needles. In a modification all the dial needles may be replaced by the guides and this produces a fabric in which only the yarn M is knitted, the yarn LI and TO being omitted but in which the yarn TV is wound around every needle loop in the fabric as a warp yarn. Knitting machines:-As described above the yarn guides 48, 52 which feed the yarn TV below the level of the latches of the cylinder needles 3 comprise two members which form an eyelet end through which a cylinder needle can rise, the eyelet being offset so that it is positioned over the needle. In operation the guide is pushed radially outwards before the needle rises through the eyelet. The yarn at this time passes through a hole 50 in one member and lies on a ledge 52A on the other member. When the needle has risen the guide is retracted leaving a loop of yarn around the stem of the needle below the latch which is then cast off with the loops already held on the cylinder needles. The elements 48, 50 have low wide butts as opposed to the high and narrow butts of the dial needles and consequently follow different cam tracks. The cylinder and dial of the machine are driven from a shaft 24 and a further plate 54 above the fixed cam ring 14 is driven from the dial by pinions 60, 62 on a shaft 58 the plate 54 carrying the bobbins  64 of yarn TV.

Abstract: 811,362. Separating solid materials. BLAW-KNOX CO. July 17, 1956 [Aug. 24, 1955], No. 22106/56. Class 117 A mixture of hard and soft stones e.g. gravel, is fed in a single layer over the edge of a feeder 12 and drops about 7¢ to 8 feet on to a sloping rigid plate 13 whereby the hard stones rebound into a compartment 17 and are collected, the soft stones fall into a compartment 15 and are either discarded or fed to a second similar separating stage, whilst the stones falling into compartment 16 are returned to the feeder 12 and subjected to further separations. When a second stage is used the feed thereof consists entirely of the discard from the compartment 15. The walls 18, 19 separating the compartments are hinged at 18a, 19a and are adjusted so that, in both stages, the material falling into the intermediate compartment 16 has the same ratio of hard stones to soft stones as the material feed of that stage. Material passing into the compartments 17 of both stages is collected as forming the desired product; material in compartment 16 of the second stage is continuously recycled and separated, whilst that falling into compartment 15 is finally discarded. The rebound plates are preferably arranged at 22¢ degrees to the horizontal and the height d between the impact line and the tops of the walls 18 19 is small. The feed material is preferably wet so that the softer and more absorbent stones may be more effectively separated. Graphical data is given indicating the effectiveness of the separation with change in drop height, and showing the effect of varying the horizontal distances of the tops of the divider walls from the impact line. Specification 808,526 is referred to.

Title: Improvements in and relating to slicing machines
IPC: B26D7/32
Filed: 1926-09-08
Abstract: 277,488. Fitzpatrick, H. D., (Maatschappij tot Vervaardiging van Snijmachines Vodgens can Berkel's Patent en van Andere Werktuigen). Sept. 8, 1926. Cutting slices in succession.-In a disc-knife reciprocating table machine, a horizontal or substantially horizontal slice receiver is adapted to, move in conformity with the movements of the article being sliced so that the slices lie down flat and automatically stack themselves, an abutment movable with the receiver preventing the slices from being dislodged from the stack. As shown in Figs. 2, 3, a bracket 15 on the base 10 carries bearing bushes 17, 18 fcr a threaded rod 26 which carries at its upper end the slice-receiving plate 39. A spider 19 is journaled on an upward projection of the bush 18 and carries a bracket 20 extending below the lower face of the bracket 15. The spider 19 carries upright walls 36, 37, 38, the portion 36 being curved to permit the oscillation of the receiver about the axis of the screw 26. A ratchet wheel 22 is interposed between the bushes 17, 18 and is engaged by a pawl 24 slidable in a sleeve 25 in the bracket 20, a spring being arranged to press the pawl against the wheel 22. Retrograde motion is prevented by a spring-pressed detent 23 housed in the bracket 15. The threads of the rod 26 are engaged by a spring-pressed ball 28 carried in a sleeve in the wheel 22. In operation, the spider 19 is oscillated by a rod 31 pivotally connected to the spider at 32 and to a dependmg pin 33 carried on a, bracket 34 on the reciprocating carriage 11. With the arrangement shown, the peripheral speed of the wall 36 is slightly greater than the speed of the carriage 11 whereby the slices, as they fall on the plates 39, are slightly stretched and prevented from curling. The plate 39, since it is housed within the walls 36, 37, 38, reciprocates with the spider 19. In one direction, the plate 39, screw 26 and wheel 22 move in unison, but in the other direction, the wheel 22 is held by the detent 23 so that the relative movement of the screw 26 and wheel 22 produces an intermittent depression of the screw 26 and the plate 39 secured thereto. When the ball 28 reaches the groove 40 the downward movement ceases and the plate 39 is again elevated by pulling upwards on the knob 41, the ball 28 riding over the rounded threads of the screw 26 which is provided with a collar 27 for limiting the upward movements. The slice deflector is adjustably screwed to a swiveling square-sectioned post 43 which is resiliently retained in the operative position by a. leaf-spring 49. A slice support 54 is arranged at the bottom of the deflector 42 and is carried by a bracket 55 secured by bolts 56 to the base 10. The lower edge of be slice is also supported by a projection formed on the deflector at a slightly lower level than the support 54. The deflector 42 is so curved that the slice is deposited properly on the plate 39. The downward steps of the plate 39 are preferably greater than the feed steps of the meat table.
