Title: Improvements in and relating to liquid sprays
IPC: B05B1/30
Filed: 1958-09-29
Abstract: 878,644. Spray-producers. LAMBTON, C. W. March 26, 1959 [Sept. 29, 1958], No. 31102/58. Class 69 (3). A casing 1 with a liquid inlet 2 has two concentric spray outlet nozzles, the outer one being formed between the periphery of a circular flange 4 of a sleeve 5 and a surrounding bore 3, and the inner one being similarly formed between a disc 7 on a plunger 8 and a bore in the sleeve. Axially extending grooves 6, Fig. 3, on the peripheries of the flange and disc provide apertures with their surrounding portions, and the grooves have gradually decreasing width from their upper or inner ends. Simultaneous regulation of the nozzles is provided by a shaft 11 having eccentric cams 13, 14 engaging, respectively, the sleeve 5 and the plunger 8, so that by rotating the shaft by a lever 17 the flange and disc are moved axially to vary the outlet apertures. In the embodiment of Fig. 2, a tubular member 20 has a threaded part engaging within a boss 18, and an axially grooved disc 21 co-operating with the inner wall of a ring 23. The periphery of the latter is grooved and co-operates with the casing wall, and a flange 24 of the ring is threaded to the member 20 at 26. Thus by rotating the tubular member, the disc 21 and ring are axially displaced to adjust the spray nozzles, relative adjustment being obtained by providing the threads at 19 and 26 of different pitch. Rotation of the ring is prevented by a pin 27 axially slidable in the boss. Specification 878,643 is referred to.

Filed: 1970-06-29
Abstract: 1298412 Envelopes for microfiche GAS COUNCIL 27 July 1971 [29 June 1970] 31403/70 Headings G2A and G2C [Also in Division B6] Each of a series of envelopes, intended for use with microfiche, has one side of opaque material with a transparent window area, the window areas increasing in number along the series. As shown, each envelope is made from a pair of transparent thermoplastic sheets welded together along edges 3, 4 and 5, the fourth edge 6 being left open. One or both sheets is coated with opaque black paint over the area 15, leaving one small corner area 17 uncoated, i.e. transparent. This area corresponds to one exposure frame 9 on the microfiche 8. After this particular frame 9 has been exposed and fixed, the sheet 8 is placed in the envelope. This can now be mounted in a projector and the image area 9 projected on to a screen. The remaining area of the microfiche, which is still unexposed, is thus shielded by the opaque coating from the effects of radiation. When a second frame on the microfiche is exposed and fixed, it can now be placed in a second envelope which has two areas such as 17 left transparent. The envelopes shown are intended for use with a microfiche sheet having sixty exposure areas, arranged in five rows of twelve each. Thus there are sixty envelopes in the complete series. Fig.4 shows the fifty-sixth envelope, with the microfiche sheet inserted, and which has fifty-five exposure frames visible through the transparent part of the envelope, and only the last five frames still covered by an opaque area.

Abstract: 632,896. Hare carriages for greyhound racing tracks. RAYNER, W. J., and FARIAM, A. S. Nov. 28, 1947, No. 31588. [Class 132 (i)] A hare carriage for a greyhound racing track is provided with a rearwardly. extending spigot in advance of which is a transversely extending notched bolt, a cylinder on which the hare may be mounted and which is adapted to receive the spigot and has therein a coiled spring, and an arm on the cylinder adapted to be engaged by the bolt when the cylinder has been slidden on the spigot to compress the spring, the arm passing through the notch of the bolt when the bolt is in one position and being engaged by the bolt when it is in a second position. Figs. 1 and 3 show the part of the carriage a by which the hare is moved which has at its top a spigot b and at its bottom a housing c for a transverse bolt d with head f and grooved peripherally at e; a spring g urges the bolt laterally to a. The hare structure includes a cylinder h in which is a coiled spring and at the ends of the cylinder are arms o and p on which the hare may be mounted ; the arm p extends downwardly at q to an extent greater than the distance between the axis of the spigot b and the periphery of the bolt d but less than the distance between the axis and the bottom of the groove e. The two parts are assembled as shown in Fig. 21 : the bolt d is pressed back against the spring g, the cylinder h is slidden along the spigot b thus compressing the spring j until the end of the arm q is in advance of the bolt d; thus when the bolt d is released the end of the arm q will be engaged. To release the hare from its carriage, a framework through which the carriage passes on its circuit round the track is described. This framework engages and forces back the head f of the bolt, whereby the cylinder h is released to the action of its spring j and ejected rearwardly from the part a.

Filed: 1956-10-19
Abstract: 813,540. Pressure-sensitive adhesive tapes. NORTON CO. Oct. 19, 1956 [Oct. 20, 1955], No. 31950/56. Class 140. A pressure-sensitive adhesive tape having improved release characteristics comprises a backing having a presure-sensitive coating on one surface and a backsize coating on the other surface, said adhesive and backsize coatings being in face-to-face relationship when the tape is in roll form, the adhesive and backsize coatings containing a release agent which may be incorporated in the formation of the coatings, such that the concentration of release agent in the adhesive coating is between 2 and 50 per cent of the concentration of the release agent in the backsize coating or the ratio of the concentrations of the release agent in the adhesive to backsize coatings is between 2 : 100 and 50 : 100, so that the release agent will not migrate from the backsize coating to the release coating upon ageing of the tape and the adhesiveness of the adhesive coating to other surfaces is not impaired by the amount of release agent therein but the adhesive coating will not tightly adhere to the backsize coating. The release agent, e.g. polyvinyl carbamate such as polyvinyl N-alkyl carbamate having N-linked alkyl terminal chains of more than 5 carbon atoms, or vinyl ester-alkyl maleate copolymers such as vinyl acetate - mono - octadecyl maleate copolymer, may be sufficiently incompatible with the other components of the backsize or adhesive coatings as to tend to concentrate in the outer contacting portions of said coatings. The adhesive coating may be applied as a dispersion or solution in a solvent such as toluene, heptane, or benzene, to both surfaces of the backing, e.g. saturated creped paper, and the adhesive repellent surface is introduced as a liner intercalate in the tape roll. The pressure-sensitive adhesive may be of the rubber resin type and may contain latex crepe, polyisobutylene, cyclized rubber, ester gum, para-cumarone resin, wood resin and hydrogenated indene-coumarone resin. The backsize coating may be a synthetic resin containing amino-aldehyde-alcohol reaction products, e.g. urea, formaldehyde and butyl alcohol, blended with an oil-modified alkyd resin plasticizer, e.g. castor-oil-modified alkyd resin.
