Title: Improvements in or relating to the preparation of photographic diazotypes
IPC: G03C5/18
Filed: 1929-04-20
Abstract: 332,552. Grinten, F. van der. Feb. 22, 1929, [Convention date]. Diazotype processes.-In the preparation of diazo prints, sizing material is included in the developer, or is applied to the prints after development, in order to prevent the spreading of ink lines subsequently drawn upon the prints. The prints are made on material which is not appreciably sized, or from which the sizing has been partially removed, in order that the support may be completely saturated with the diazo compound. The sizing materials may comprise substances with good sizing action such as milk, casein, albumins, also soaps, fat and overfat soaps and pure soaps such as potassium or sodium stearate, or substances which can be finely divided in the developer such as lime, chalk, and flour. These substances may be used alone or in conjunction with substances of little sizing action, such as glue, gelatine, and sugar. Examples are described in which supports sensitized with 1- diethylaminobenzene-4-diazonium chlorostannate or 1-diisoamylamino-benzene-4-diazonium chlorostannate are developed with various developers which may include sizing materials and also substances for preventing the prints from turning yellow.

Title: Improvements relating to polyethylene terephthalate film having improved physical properties
IPC: B29C55/14
Filed: 1953-05-05
Abstract: The physical properties of polyethylene terephthalate film are improved by stretching the substantially amorphous film first in one direction, i.e. either longitudinally or transversely, to the extent of 250 to 325 per cent at a rate of at least 400 per cent per minute, and then in the other direction to the extent of 250 to 325 per cent at the same rate, and finally heat-setting the biaxially stretched film at 150-250 DEG  C.  Preferably the longitudinal stretch is effected at 80-90 DEG  C., and the transverse stretch at 95-110 DEG C.  Prior to the second stretching the film is preferably preheated to 90-95 DEG  C.  The film is preferably stretched to the same extent in each direction and heat-setting is effected with the film under tension.  The process may be continuous, a series of rollers effecting the longitudinal stretch and a tenter frame effecting the transverse stretch.  The films may be employed as packaging material and as a dielectric in electrical applications.  Specifications 603,840, 609,797, 610,202 and 743,497 are referred to.

Title: Improvements in infrared-excitable rare earth oxysulfide luminescent materials
IPC: C09K11/84
Filed: 1969-03-10
Abstract: 1,248,299. Luminescent materials. GENERAL ELECTRIC CO. 10 March, 1969 [28 March, 1968], No. 12467/69. Heading C4S. A luminescent oxysulphide of La, Gd and/or Y is activated by Er and Yb. It has a formula (Ln 1-x-y .Yb x .Er y ) 2 O 2 S, where Ln is La, Gd or Y, 0À4>x>0À05 and 0À1>y>0À0025. The oxysulphides are prepared by co-precipitating Yb and Er with La, Y or Gd in the form of an oxalate using oxalic acid and the appropriate nitrates. The oxalate is heated in air to form the oxide which is converted to oxysulphide by firing in H 2 S and N 2 . Alternatively mixed oxides are heated with Na 2 S 4  in an inert atmosphere. Visible light is emitted by the phosphor when excited by infra-red light. The longer wavelength light is produced by electrons excited by two photons successively before emission. Similar known phosphors having this property referred to are ZnCdS : Ag, Cu; LaCl 3  : Pr; NaYb(WO 4 ) 2  : Er; CaWO 4  : Er and (Ca, Ba)F 2  : (Tm, Er, Ho)Yb.

Inventor: DANIELS BARRIE
IPC: D02G1/14
Filed: 1966-03-22
Abstract: 1,172,361. Crimping filaments. IMPERIAL CHEMICAL INDUSTRIES Ltd. 9 March, 1967 [22 March, 1966], No. 12574/66. Headings D1F and D1W. Continuous filaments are crimped by heating them while they are travelling towards a first assembly of denticulated members, passing them through the first assembly and through a second assembly of denticulated members which impart a crimp of different characteristic from that imparted by the first assembly. As described, the two assemblies comprise two pairs of gear wheels disposed in a draw frame between a heated snubbing pin and the draw rolls. Alternatively, the draw rolls may be replaced by the second pair of gear wheels. The filaments may be cooled by an air jet between the two pairs which, to produce crimps of different characteristics, may differ in diameter, speed of revolution, or number of teeth per inch or may be disposed in different planes. Some of the filaments may have one crimp frequency, others may have a second crimp frequency, while the majority of the filaments may have the two frequencies superimposed. The second crimping may produce an irregularity of crimp. The speed of the gears wheels may be varied cyclically, or intermittently at random or regular intervals. The filaments may be fed to the draft frame directly from the extruder, be passed through an interlacing nozzle before wind-up, and be composed of nylon, a polyester or a polypropylene. Specification 1,172,362 is referred to.

Filed: 1954-04-30
Abstract: 757,828. Stud and socket fasteners. AVIATION DEVELOPMENTS, Ltd. April 30, 1954, No. 12689/54. Class 44. A quick-release fastener comprises a radially apertured tube 10 having a head portion 12, a locking element 25 movable in the aperture, a plunger 18 axially slidable in the tube to co-operate with the locking element 26, and a cam for axially moving the plunger 18 to release or lock the fastener. In the fastener shown in Figs. 1 and 10, the tube 10 is sealed by a plug 27 at one end and is connected to the head portion 12 by studs 13. The head portion 12 is rectangular in cross-section and carries a stirrup-shaped lever 16 the ends of which form discs 15 rotatably housed in recesses in opposite sides of the head portion. Slidably mounted in the tube 10 and projecting into the head portion is a plunger 18 engaged by a transverse pin 20 that is slidable in the longitudinal slots 22 in the sides of the head portion 12 and which projects through arcuate cam-slots 17 in the disc portions of the lever 16. The ends of pin 20 carry bushes 21. A locking element 25 is engaged by a spigot on the end of the plunger 18 so that if the plunger is advanced the locking element is projected from the position in which it lies flush with the tube 10. The locking element may be formed by ball-bearings projected by a ramp on the end of the plunger. The plunger is advanced by swinging the lever 16 from the position shown in Fig. 1 to that shown in Fig. 10, during which movement the arcuate camslots 17 shear across the slots 22 and propel the pin 20 along the slots. The edges of the discs 15 are notched at 32 to engage the ends of a spring strip 30 to hold the lever in its extreme positions. Holes 36 in projecting parts of the lever 16 coincide with a groove 37 in the head portion 12 when the fastening is closed and a pin can be passed through both holes to lie in the groove and lock the fastener. Washers 34 are held by the ends of pin 20 to cover the cam-slots 17 and their peripheries carry apertured lugs by which the fastener may be suspended. An alternative form of connection between the pin 20 and the lever is shown in Fig. 12 where the disc portions slide between the sides of a rectangular recess 40 and are eccentrically pivoted to the pin 20 which slides laterally in the slot 22 as the discs rotate and move transversely across the head portion 41. The undersides of the discs are grooved at 47 to engage a U-shaped spring 44 housed in a recess in the head portion to hold the lever in its extreme positions.

Title: Method of curing of concrete
IPC: B28B11/24
Filed: 1956-04-25
Abstract: Concrete is cured by covering it with a sheet of polythene of thickness between 1/1000 inch and 1/2000 inch and of such weight per unit area that it adheres to the film of water normally present on the surface of the concrete without breaking the surface tension of the water.  The polythene is secured at one end, e.g. by a clamp rod, and unrolled over the uncured concrete, is held in position by suction between it and the moisture layer on top of the concrete sufficient to prevent it from being displaced by wind, and left until the concrete is set.  The Provisional Specification refers also to the use of "Cellophane", "Fluon" (both Registered Trade Marks), nylon and polyvinyl chloride for the covering sheet.

Title: Improvements in or relating to preparation of liquefied natural hydrocarbon gas
IPC: F25J3/08
Filed: 1963-04-01
Abstract: 996,929. Cold separation of gas mixtures. SOC. D'ETUDES DU TRANSPORT ET DE LA VALORISATION DES GAZ NATURELS DU SARAHA S.E.G.A.N.S. April 1, 1963 [April 5, 1962], No. 12766/63. Heading F4P. A process for separating a liquefied natural hydrocarbon gas mixture containing volatile inert gases such as nitrogen and helium into a sub-cooled liquid fraction and into a gaseous combustible fraction comprises expanding feed liquid from lines 1, 2, Fig. 1, into a flask B 1 , withdrawing the liquid fraction so produced through a line 3 and sub-cooling it in exchangers E 2 , E 3  arranged in cascade, withdrawing the combustible gaseous fraction through a line 6 and partially condensing it in exchangers E 5 , E 6  also arranged in cascade followed by further cooling the product liquid fraction and liquefying the combustible fraction in exchangers E 4 , E 7  cooled by a return flow of liquid combustion gas after expansion at a valve in a line 8; product liquid fraction being withdrawn through a line 5 and product combustion gas containing inert gas being withdrawn through a line 9. As shown, liquid feed in line 1 is sub-cooled in an exchanger E 1  which forms the high pressure stage of a threestage methane refrigerant cycle, the medium and low pressure stages of which comprise exchangers E 2 , E 5  and E 3 , E 6  respectively. The inert volatile gas content of the liquid hydrocarbon product may be reduced by substituting a column V 1 , Fig. 4, in place of the flask B 1  and inert gases are separated from the combustible gas in line 6 by means of a separating column V 2  from which liquefied combustible gas is withdrawn through a line 10 and after being sub-cooled in cascade exchanger E 6  and in exchangers E 7a , E 7b  in counterflow to expanded gas the latter is discharged as product through line 9. A portion of liquid combustion gas leaving exchanger E 7b  through line 8 is diverted along a line 11 and cools the head of column V 2  from which inert gases are withdrawn through a line 13 and are passed through a molecular sieve 14. The carbon-dioxide content of the mixture of liquid hydrocarbons withdrawn from the base of column V 1  through line 3 and having been sub-cooled in exchanger E 2  is removed by expansion into flasks B 3 , B 4 , Fig. 6 (not shown) having filter screens therein.
