Abstract: 1304903 Reciprocating pumps SOC TECHNIQUE DE PULVERISATION 6 July 1970 [7 July 1969 26 March 1970] 32652/70 Heading F1A An atomizer pump for mounting on a liquid container 2 comprises a piston 11 with a lostmotion sliding connection to a rod 7 operated by a button 8 incorporating an atomizer nozzle 10. Downward movement of button 8 moves rod flange 7a to engage piston 11 after moving valve 15 downwardly to close opening 16 in hollow piston 13 and moving the hollow piston 13 downwardly to open a clearance between portion 13a and piston 11. Continued downward movement causes liquid in pumping chamber 14 to be discharged via said clearance and rod passage 9a, 9. Upward movement of the piston assembly is effected by spring 17 which first moves valve 15 to uncover opening 16, and hollow piston 13 to close said clearance, so that liquid is drawn into chamber 14 from dip tube 6 via chamber 5 and opening 16. The container is vented via opening 12 which is closed by engagement of piston surface 11b with sleeve 3 in the upper end position of piston 11. In Fig. 7 (not shown), the arrangement is such that rod 7 engages piston 11 without moving piston 13 downwardly to open the clearance between piston 13 and piston 11, so that discharge does not take place until pressure has built up in chamber 14 sufficiently to move piston 13 downwardly to open the clearance. Rod 7 and valve 15 may be made in one piece. In Fig. 5, valve 15 is omitted and a passage 13b in piston 13 connects dip tube 6 to chamber 14 during the suction stroke via passage 11c in piston 11. On the discharge stroke, rod 7 moves piston 13 downwardly so that passage 11c communicates with rod passage 9b and passage 13b is closed.

Filed: 1966-07-20
Abstract: 1,142,384. Transparency copying. K. S. PAUL & ASSOCIATES Ltd. 20 July, 1967 [20 July, 1966], No. 32664/66. Heading H4F. [Also in Division G2] The Specification describes a copying system for copying a colour transparency and a mask containing an image of lettering &c. which is superimposed in monochrome &c. on the reproduction of the transparency, wherein the mask image is practically transparent to the visible light scanning the transparency, but is practically opaque to a provided source of infra-red light, the infra-red light being detected, after scanning the mask, by a photo-electric cell, Fig. 6, to produce a signal which controls the passage of signals derived from the visible light scanning of the transparency, to a glow modulator light source forming part of the reproduction apparatus. Thus when a drop in the output of the infra-red photo-cell indicates that part of the mask image is being scanned, a change-over switch 21 causes the glow modulator tube to be modulated by the output of generator 22 instead of said derived signal. The colour spectrum of a " black " area of the colour transparency is shown in Fig. 2, showing that in the infra-red (above 7 microns) the density of the transparency decreases rapidly, until a state of near transparency exists at 1À0 micron. The colour spectrum of an exposed part of the infra-red mask is shown in Fig. 3, showing near transparency at visible wavelengths (up to 7 microns) and near opacity at infra-red wavelength 1À0 micron. A tungsten lamp 1, Fig. 5, having considerable radiation at 1 micron, is used as the light source, and a scanning spot therefrom is focused on the sandwiched colour transparency and mask 2. The modulated light beam is dispersed by prism 8 and reflectors 11, 12 and 17 are so placed, that radiation received by photocells 19, 15, 14 and 16 is at infra-red, red, green and blue wavelengths respectively.

Filed: 1964-08-12
Abstract: The invention comprises monoazo dyestuffs of the formula <FORM:1067518/C4-C5/1> wherein A is CH3 or an unsubstituted or substituted carbonamide group, R1 is a diazo component of the benzene, naphthalene or heterocyclic series free from -COOH and -SO3H groups and R2 is a dialkylaminosulphonyl group.  They may be obtained by diazotizing an amine of the formula R1-NH2 and coupling with a coupling component of the formula <FORM:1067518/C4-C5/2>  A preferred method of diazotization consists in adding finely pulverized amine to freshly prepared nitrosylsulphuric acid at 0 DEG  to 5 DEG  C. The coupling of diazotized amines with the coupling component is preferably carried out in an aqueous or aqueous-organic medium under weakly acid, neutral or weakly alkaline conditions when the amine is of the benzene series.  The coupling of diazo components of those amines which are only diazotizable in concentrated H2SO4 or H3PO4 is effected preferably in aqueous-organic medium under strongly acid to weakly acid conditions.  The dyes may be used for the dyeing, padding or printing of linear aromatic polyesters in the forms of filament, yarn, tops, woven or knitted fabrics.  The dyes may also be applied to cellulose acetate, cellulose triacetate polyamide and polyvinyl fibres by dyeing, printing or padding (see Division D1).  The dyes give yellow or greenish-yellow dyeings.  Examples are given for the production of the dyes.ALSO:1 - Dimethylaminosulphonyl - 3 - methyl - 5 - pyrazolone is obtained by suspending 3-methyl-5-pyrazolone in dilute aqueous KOH, adding thereto dimethylamino-sulphonyl acid chloride, refluxing the solution and separating the product on cooling. The compound is useful as an intermediate for use in preparation of dyes (see Division C4).ALSO:Linear aromatic polyester, cellulose acetate, cellulose triacetate, polyamide and polyvinyl fibres or fabrics are dyed with a mono-azo dyestuff of the formula: <FORM:1067518/D1-D2/1> wherein A is CH3 or an unsubstituted or substituted carbonamide group, R1 is a diazo component of the benzene, naphthalene or heterocyclic series free from COOH and SO3H groups and R2 is a dialkylamino-sulphonyl group.  Polyester fibres can be exhaustion dyed in the presence of a carrier at 80 DEG C. to 125 DEG C. or in the absence of a carrier in a closed vessel at about 100 to 140 DEG C.  These fibres may be padded or printed with aqueous dispersions of the dyes and the pad dyeings or prints fixed at about 140-230 DEG C.  Secondary cellulose acetate is dyed preferably at about 65 to 80 DEG C and cellulose triacetate at up to about 115 DEG C.  The optimum pH range is 2 to 9.  Conventional dispersing agents and thickening agents may be used where appropriate.  Examples are given for the dyeing of polyester fibres, viscose rayon, and cellulose acetate.

Abstract: 1,005,167. Sensing records. NATIONAL CASH REGISTER CO. Aug. 22, 1963 [Aug. 29, 1962], No. 33203/63. Heading G4M. A record carries binary-coded characters each of which is represented in true and inverse form by marks in parallel rows 10, 11, Fig. 1. Each character is preceded by a mark 12 in each of rows 10, 11. The record is scanned manually by means of the apparatus shown in Fig. 3. The base 22 has guide marks to facilitate correct alignment of the apparatus with a row of characters to be read. Cylinder 33 is slidable on guides 29 along the direction of the row of characters. Light from a lamp 34 is focused on a slit 38 and an image of the slit is focused on the record 23 by a lens 42, the optical axis of lens 42 being so inclined that light reflected from record 23 is focused by lens 42 on a pair of photodiodes 41 for sensing rows 10, 11 respectively. Signals from photodiodes 41, 41<SP>1</SP>, Fig. 6, are supplied to respective shift-registers U1-U6 and L1-L6, and both sets of signals are applied to OR gate 59 to provide shift pulses for the registers. When the pair of " 1's " from marks 12 enter stages U6, L6 an error check is performed. Corresponding outputs of stages U2-U5 and L2-L5 are gated together (AND gates 66-69) and AND gate 73 which is enabled by the output of AND gate 70 passes any error signal from OR gate 71 to an error flip-flop 74. At the same time, stages U1, L1 both contain " 1's " from the marks 12 of the next character, gate 78 is enabled, and provided no error has been detected, gate 77 provides an output to reset stages U2-U6 and L2-L6 and to transfer the information in L2-L6 to storage flip-flops 79. In successive cycles, the output of gate 77 effects data transfer between successive sets of storage flip-flops 79-83, and the information is displayed at 57 after decoding. Other error detection circuits are mentioned, for example, the number of characters sensed may be counted, the number of bits in a character may be counted, the counter being reset to zero by a mark 12 and indicating an error if it is not at " 4 " when a mark 12, other than the first, is sensed.
