Title: Improvements in collapsible boats
IPC: B63B7/06
Filed: 1942-07-30
Abstract: 559,746. Collapsable boats. GRIMSTON, F.B.S. July 30, 1942, Nos. 10695 and 17480. [Class 113 (ii)] A collapsable boat comprises a skin 25 of resilient material, e.g. plywood, which lies flat when the boat is knocked down, the longitudinal edges being secured to flexible gunwale stringers 29 arranged to be drawn by a winch-operated cord and pulley system 51 up against the edges. of a curved deck frame 36 whereby the skin is forced to take a compound curvature when the boat is erected. The skin has a V-notch 26 at one end the edges of the notch being reinforced by members 27 which meet to form the stem post when the boat is erected. The deck frame is pivotally attached at its forward end to arms 32 pivoted to the framework of a floor 20 to which the transom 31 is hinged, the deck frame also being pivotally attached to the upper corners of the transom. Thus the deck frame and transom may be lowered to lie flat on the floor 20 when the boat is knocked down. Latching arrangements are provided for locking the gunwale stringers against the sides of the deck frame, Fig. 9 (not shown) and for locking together the lower ends of the members 27 forming the stem post, Fig. 12 (not shown). A modified stem construction comprising metal reinforcing and rubber packing is described with reference to Figs. 17 to 22 (not shown).
Patent GB-773366-A (GB)
Title: Calculator
IPC: G06G1/08
Filed: 1954-04-12
Abstract: 773,366. Calculating-apparatus. ZUR, E., and TECHEN ENTERPRISES, Ltd. April 12, 1955 [April 12, 1954], No. 10759/54. Class 106(1). The logarithmic scale of a slide rule is set off along consecutive parallel and equidistant lines S, Fig. 1, extending between opposite sides of a parallelogram ABCD (shown as a rectangle) in such manner that auxiliary lines p connecting the ends of adjacent S lines are parallel to the other two sides of the parallelogram. The resulting two-dimensional scale or grid provides greater accuracy than a simple linear scale of similar dimension. The embodiment of Fig. 3 shows two such scales marked respectively on a base-plate N and an overlying transparent plate M. The scales are manipulated in a manner similar to a conventional slide rule, using the parallelogram points A and C as the terminal points of the scales and maintaining the S lines, along which the scales are marked, always parallel. A traversible pointer Y is mounted on the plate M and serves as a cursor. The grid scale may be omitted from the plate M, since the pointer Y can be set from the scale of the plate N after adjusting the two plates to bring the parallelogram points ABC and D into coincidence. Guides may be provided for maintaining parallelism of the S lines of the two scales. The base-plate scale may be repeated in a succession of scales arranged side by side, as indicated in Fig. 1, or the base-plate could take the form of a frame in which any one of a set of scale bearing cards is inserted. In Fig. 4, grid scales, similar to that of Fig. 1, are marked on a stock M<SP>1</SP> and a slide N<SP>1</SP>, a cursor III co-operating with the two scales. To ensure accuracy of reading, despite the near parallelism of the index line of the cursor and the graduated S lines of the scales, the index line is marked on a subsidiary slide IV carried by the cursor III and crossed by lines b, c, d and e spaced correspondingly to the upper and lower margins of the grid scales. A further slide V carried by the slide IV bears an adjustable cursor line f. These slides IV and V are used for adding the ordinates of data points on the grid scales to locate the result point at the intersection with an S line. The scales may be provided on cylindrical members instead of on flat surfaces, as in the above embodiments.

Abstract: 1,042,311. Aerating liquids. WATNEY COMBE REID & CO. Ltd. March 13, 1963 [March 21, 1962], No. 10795/62. Heading B1C. In a method for effecting the dissolution of gas in a liquid, e.g. wort, an apparatus may comprise an inverted U-tube having legs 4, 6 of glass and a U-bend 5 of stainless steel; there is a discharge pipe 7 rising to a point 8 above the U-bend to eliminate siphonage effects, a liquid inlet 9 and a gas inlet in the form of a porous thimble 3. In operation the wort first rises to fill the leg 4 and cascades into the leg 6 until it is partly filled; the outlet is then opened and oxygen from a cylinder 1 admitted so that partial oxygenation takes place in the leg 4 and further oxygenation in the leg 6 due to the liquid shower 11 which takes place in an atmosphere 10 of oxygen. When the flow rate is properly adjusted the wort leaves the apparatus substantially free of bubbles. As all the gas supplied is dissolved a precisely controlled degree of oxygenation is obtained. The U-bend 5 is detachable for cleaning and 12 is a gas flow-meter or steriliser.

The dyes are prepared by condensing an aminoazo dye of formula <FORM:0970475/C4-C5/2> with the acid halide or anhydride of an acid which contains a group as specified above. Specified anhydrides and acid halides include chloromaleic anhydride, propiolyl chloride, acrylyl chloride, chloroacetyl chloride, sulphochloroacetyl chloride, b -bromo- and -chloropropionyl chloride, a  : b -dichloropropionyl chloride, tri - and tetra - halopyrimidines, 5-nitro - or - methyl - or - cyano - 2,4,6 - trichloropyrimidine, 5 - carboxy - or - carboethoxy - 2,4 - dichloropyrimidine, cyanuric chloride or bromide and their primary condensation products with ammonia or an organic mercaptan, hydroxy compound or primary or secondary amine. If the radical Z in the monoazo dye is a heterocyclic radical containing two chlorine or bromine atoms which are both in o-position to nuclear nitrogen atoms, one or both of these atoms may be replaced by a further reaction to give a radical containing at least one reactive group.  Thus the following groups may be introduced:  an amino or substituted amino group by reaction with ammonia or an amine; an alkoxy or aryloxy group by reaction with an alcohol or phenol; a sulphonic acid group by reaction with an alkali metal sulphite; a thiocyano group by reaction with potassium thiocyanate; a group of formula <FORM:0970475/C4-C5/3> wherein Y is the group of atoms necessary to form a 5- or 6-membered heterocyclic ring by reaction with an alkali metal salt of a mercapto-heterocyclic compound; a quaternary ammonium or pyridinium group by treatment with pyridine or a tertiary amine; a group of formula <FORM:0970475/C4-C5/4> wherein R1 and R2 are alkyl, cycloalkyl, aryl or aralkyl groups or together with N from a 5- or 6-membered ring by reaction with an appropriately substituted alkali metal dithiocarbamate; and a group of formula <FORM:0970475/C4-C5/5> wherein R3 and R4 are hydrogen atoms or alkyl, aryl or aralkyl groups by reaction with a thioamide. The dyes are used to dye or print cellulose textile materials, in conjunction with an acid-binding agent, in reddish-yellow shades. The preparation of the dyes is described in examples.  Specifications 797,946, 822,047, 838,307 and 891,601 are referred to.

Abstract: 973,499. Pressure-relieving devices; valves. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 13, 1962 [March 27, 1961], No. 11191/61. Heading F2V. Means for relieving pressure in a conduit A containing radio-active or toxic gases comprises a domed bursting disc 24 separated from a second, flat bursting disc 23 by a low-pressure chamber so that the pressure at which the disc 24 bursts is independent of the pressure in a receiver 1 to which the conduit discharges. The disc 23 bursts at a low pressure differential but is supported to withstand high pressures in the receiver. The conduit A communicates with the disc 24 through apertures 4 and conical valve surfaces 3a, 7 of which the latter is movable under the loading of a spring 9 surrounding a sealing bellows 8 to isolate the conduit A on outward movement of a rod 10 under the control of a bellows-sealed screw 16. A cover 1b together with the rod 10 and a shield plug 12 may be removed after which the bursting disc assembly may be replaced. A number of conduits A each with a bursting disc and valve assembly may discharge into the single receiver. A single bursting disc similar to the disc 23 allows discharge of the receiver to a conduit D. This disc, however, is reversed to withstand pressure in the conduit D, but otherwise the parts associated with the conduit D are similar to those on the conduit A. The Provisional Specification describes a modification in which the valve surfaces 3a, 7 and the bellows 8 and spring 9 are omitted, and a relief valve is fitted to the chamber between the two bursting discs.
