Title: Process for the production of coarse crystals of urea
Inventor: SCUFFHAM JAMES BARRIE
IPC: C05C9/00
Filed: 1966-06-02
Abstract: 1,148,573. Coarse crystals of urea. POWERGAS CORP. Ltd. 31 May, 1967 [2 June, 1966], No. 24529/66. Heading C2C. Coarse crystals of urea are obtained from an aqueous solution of urea by a process which comprises incorporating in the aqueous urea solution to be crystallized, from 0À1 to 6% by weight of one or more of the compounds triuret, ammelide, formamide and guanidine carbonate, forming urea crystals by producing a supersaturation of urea in the solution and allowing the crystals to grow, and separating urea crystals from the mother liquor. The separated urea crystals may be washed with a saturated solution of urea of low biuret content, the washed crystals separated from the washing solution, and the washing solution recycled to mix with the aqueous urea solution to be crystallized.

Title: Packaging container
Inventor: BLUHM HANS JOACHIM
IPC: B65D55/08
Filed: 1969-05-14
Abstract: 1,237,323. Container closures. SCHMAL. BACH - LUBECA - WERKE A.G. 14 May, 1969, No. 24584/69. Heading B8T. A closed elastic sealing and opening ring 8 which may be of natural rubber or synthetic composition is introduced in a liquid or plastic condition into the sealing space formed by the outer roll 2 of the container 1 and the edge surface 6 of the container lid 3 and allowed to set in situ. The sealing composition is introduced when the combination of lid and container is inverted, the sealing space thus forming an annular opening into which the composition is poured from the top, Fig. 4d (not shown). A gripping tab 9 of identical material to the sealing ring is introduced immediately after the introduction of the sealing composition thus sealing jointly with the composition. However the gripping tab may be previously attached by means of adhesive 14 to the container body 1, thus ensuring correct positioning of the tab on introduction of the liquid or plastic composition. The lid end has a closed rolled rim 11 which can be effected either before the injection of the sealing composition or after, thus providing resistance to bursting pressure. To open the container, the gripping tab 9 is released from the adhesive 14 and drawn obliquely downward. The sealing and opening ring can thus be drawn out through the joint 10.

Title: Improvements relating to the treatment of textile materials
IPC: D06M13/335
Filed: 1930-10-15
Abstract: Yarns, filaments, tapes, straws, ribbons, bristles and like textile materials are conditioned by applying thereto a hygroscopic solid in a medium comprising an alcoholic body.  The invention is specially applicable to yarns &c. consisting wholly or largely of organic derivatives of cellulose.  The alcohols may be di-and poly-alcohols, e.g. ethylene glycol, diethylene glycol, propylene glycol, and glycerin.  To prevent change in volume, viscosity, or concentration of hygroscopic liquids, water is preferably added in amount substantially such as would be absorbed from the atmosphere.  With cellulose acetate and other organic derivatives of cellulose, softeners or swelling agents may also be added, e.g. the mono methyl and the mono and di-ethyl ethers of ethylene glycol, diacetone alcohol, and triacetone.  The hygroscopic solid should preferably be easily removable and should not affect the dyeing or the lustre or other physical characteristics of the yarn; and should be free from objectionable odour and colour.  Sodium and potassium acetates are suitable solids.  The treatment may be applied to the yarn continuously with production thereof by the dry or evaporative method; or subsequently, e.g. immediately before knitting.  Thus yarns may be passed across wicks or pads dipping into ethylene glycol containing potassium acetate.  Such application of hygroscopic solids may render separate lubrication unnecessary.  According to the Provisional Specification a lubricating liquid may also be added.

Title: Printing machine control apparatus
IPC: B41F33/08
Filed: 1963-06-20
Abstract: 1,002,772. Printing machine control apparatus. MASCHINENFABRIK AUGSBURGNURNBERG A.G. June 20, 1963 [July 6, 1962], No. 24665/63. Heading B6C. In order to avoid printing on any of the impression cylinders of a multi-colour rotary sheet printing machine consisting of a number of series arranged printing units during the starting or stopping of the machine, as the case may be, a control apparatus is used which operatively links the " on-off " control mechanism of each unit. The apparatus includes a first shaft 8, Fig. 1, arranged to be connected through an electromagnetically operated clutch 6, 6<SP>1</SP> with a main machine drive 9 in response to movement of a control lever 1 for the first unit into a print-on position, a second shaft 7 arranged to be connected through an electromagnetically operated clutch 5, 5<SP>1</SP> with the machine drive in response to movement of said control lever into a print-off position, a number of cams, such as 11, 12 and 10, 10a corresponding to the number of further printing units mounted on each shaft 8 and 7 and, for each further printing unit, a " print-on " microswitch such as 13, 14 actuable by the corresponding cam on said first shaft 8 to render the unit operative and a "print-off" microswitch 21, 21a actuable by the corresponding cam on the second shaft 7 to render the unit inoperative. The arrangement of the parts of the control apparatus is such that movement of the control lever 1 into a " print-on " position or into a "print-off" position causes the further units to be rendered operative or inoperative, as the case may be, in succession in accordance with a predetermined time interval.

Abstract: 278,524. Gregory, V. H. Oct. 6, 1926. Recording by co-ordinates.-In a recording instrument to produce a more open record the recording arm is caused to travel twice or more times the width of the record sheet by means of a compound lever arrangement, interposed' between the recording arm and the moving element of the instrument. The compound lever, as shown, comprises a main lever 4 and an auxiliary lever 5 carried by a fulcrum 13 on the lever 4. The lever 4, which is pivoted at 12, is connected by a spring 3 with the moving element 1 of the instrument and is counterbalanced by a weight 11 while the auxiliary lever 5 has a stop 14 at one end! engaging the lever 4 and is connected by a link 6 with an adjustable lever 7 carried by the spindle 8 of the pen arm 9. An adjustable abutment 16 constituted by a length of spring wire on the auxiliary lever 5 is adapted to coacts with a spring controlled stop 17 slidably mounted in an adjustable bearing 18. Where a double traverse of the pen arm is desired during the complete outward movement of the element 1, the spring of the stop 17 is designed so as not to yield by contact with the abutment 16. If, however, three traverses are desired the abutment 16 is arranged to press back the stop 17 during the last third of the outward movement of the element 1 the levers 4 and 5 being moved rigidly by their engagement through the adjustable stop 20 on the auxiliary lever.
