Title: Chemiluminescent compositions
Inventor: RAUHUT MICHAEL MCKAY
IPC: C09K11/07
Filed: 1965-11-10
Abstract: A chemiluminescent composition comprises (1) a dicarboxylic acid of formula COOH.(CO)m.(COHOH)m.COOH where m and n are less than 11, (2) an anhydrous hydroperoxide, (3) a specified dehydrating agent, and (4) a fluorescent compound; the fluorescent compound may be omitted if one of the other constituents is itself fluorescent. The dehydrating agent may be (a) a carbodiimide RN=C=NR1 where R and R1 are (normal or substituted) alkyl (C1-C16), aryl, cycloalkyl, heterocyclic, substituted alkyl, substituted aryl, substituted cycloalkyl or substituted heterocyclic, (b) an anhydride of carboxylic acid, (c) an isocyanate, (d) an anhydride of R-substituted carboxylic acid (R as above), or (e) an R-substituted isocyanate. The hydroperoxide may be H2O2 or a perhydrate. The materials may be present in a liquid diluent, or the blended solids may be stored, a diluent being added to initiate the reaction.  The reaction may also be initiated by friction, or by the addition of any one component, other than the fluorescent component, to a mixture of the others. One or more components may be contained in, e.g. a dissolvable capsule before use.  Light output may be improved by the addition of a small amount of an anhydrous acid catalyst; many examples of suitable organic and inorganic acids are given.  Fluorescent materials mentioned, emitting between 330 and 700 millimicron, include anthracenes, anthrenes, naphthacenes, stilbenes etc.

Abstract: 1,182,927. Making pipes; rolling; drawing. NIPPON KOKAN K.K. 23 Oct., 1967 [24 Oct., 1966], No. 48031/67. Headings B3A, B3M and B3P. Flanged steel pipe for use as boiler tubes is formed in two operations, the latter of which is by cold drawing, wherein the cross-sectional reduction of the flange portions 24 is greater than that of the pipe portion 20. A pipe is passed three times between a plug and cooperating roller dies 10, 12, Fig. 1A, to form a flanged pipe, which is given a further two passes between a plug and co-operating roller dies, Fig. 1B, stepped at 26 to limit the metal flow. During the final pass a plug is used having a diameter 1-5 mm. greater than that of the plug used in the preceding pass. The roller die 10 may alternatively have projecting portions (28) (Fig. 1, not shown) co-operating with recess portions (30) in the roller die 12 in order to limit flow of the flange portions of the pipe during rolling. A flanged pipe of elliptical cross-section may be formed using an elliptical mandrel (Fig. 3, not shown) and elliptical roller dies (Fig. 1C, not shown). The pipe is finally drawn to form flanges with bevelled edges 40, Fig. 6, which facilitate the welding together of adjacent pipes. The pipe may alternatively be initially formed by extrusion.

A cathode ray tube implosion protection sheath, in the form of a strip-frame having an opening corresponding to part of the slightly conical portion of the tube envelope rearward of the faceplate, is applied by placing over the tube and pressing it towards the faceplate, along the direction of the tube axis, whereby the frame is deformed, by stretching, to the exact shape of the portion of the glass envelope with which it is in contact. Optionally, adhesive may be applied to the bearing surface of the strip frame, to provide additional restraint against displacement. Angle-pieces 12, Fig. 5, may be secured to the strip-frame, and screwed to the cabinet 11 through an interposed plastics member 13. Alternatively, the angle-pieces may be secured to a separate front-frame (Figs. 1 to 3, not shown) edging the faceplate and held by means of tongues passing through apertures in a flange of the strip-frame. In a further embodiment, Fig. 6, the angle pieces are held by the engagement of a hook-shaped portion 15 over the strip-frame flange, which permits movement of the angle-piece along the flange for alignment when fixing to the cabinet, and the front edge 25 of the strip-frame is beaded. When applying the strip-frame to the tube, it is held by means of a tension ring mounted on a mandrel, while the tube rests on its faceplate on a correspondingly shaped surface.

Abstract: 1399813 I C engine valve gear; regulating INNOVATION & TECHNICAL DEVELOPMENT CO Ltd 5 Oct 1972 [27 Oct 1971] 49826/71 Heading FIB [Also in Division F2] A unit 2 for transmitting motion from a member, e.g. a cam 22, 22a, to a member to be reciprocated, e.g. an engine inlet valve 26 or push-rod, comprises a piston 16 reciprocable in a cylinder 10 which is reciprocable in a cylinder 4. Liquid introduced into the spaces B and C between the piston 16 and cylinder 10 and the cylinders 6 and 10, respectively, may escape through passages 28, 32 and 38, 42. The liquid, e.g. oil pumped from the engine sump, is fed through non-return valves 48 and 50 to the spaces B and C and escape is  controlled by a valve 56 and co-operation of the piston ports 40 with the cylinder 10, respectively. The valve 56 may be an adjustable orifice valve or spring-biased valve set to open above a predetermined pressure in the space B. In operation, with the valve 56 closed, the cylinder 10 moves upwardly with the piston 16 and downwardly, due to the force exerted by a return spring associated with the member being reciprocated, at a rate dependent upon the flow of liquid through the piston passages 38, 42 from the space C. With the valve 56 open, the cylinder 10 moves upwardly with the piston 16 but to a lesser extent dependent upon the degree of opening of the valve and moves downwardly when the piston has moved downwardly sufficiently to open the ports 40. In a further embodiment, Fig.2 (not shown), the cam 22, 22a contacts a lever (70) pivotally connected to an engine cylinder head (74) and a lever (80) pivotally connected to the piston 16, the unit 2 being mounted above the engine inlet valve 26 in the cylinder head. The valve 56 can be used as a speed regulator in addition to or in place of a carburetter throttle valve when the unit 2 operates an engine inlet valve 26.

As shown, Fig. 1, an I.R. detector 10, which may be a thermistor bolometer, is arranged at one end of a black body cavity 12 whose temperature is held constant by a controlled heating arrangement 14. A lens 16 focuses a field of view on to the detector, and a chopper 18 having highly - reflective blades (20) alternately passes the incident radiation and reflects the reference radiation from cavity 12. The output of the detector is processed and applied to a meter or recorder 25. A vane 28 is arranged outside the chopper and is mounted by a slot and setscrew - arrangement so that its position can be adjusted. The vane is at the same temperature as the chopper blades 20 and has a blackened surface. The end of the vane extends into the field of view of the detector to an extent which is adjusted so that the amount of radiation received by the detector is equal to that emitted from the chopper when it obscures the field of view thus compensating for any change in temperature of the chopper blades.
