Title: Improved closure for receptacles for sauces, jellies, mustard and similar goods
IPC: A47G19/18
Filed: 1924-03-31
Abstract: 221,750. Weyland, J. A. March 31, 1924. Stroke, limiting; single-acting bucket pumps; locking and releasing devices. - A closure for vessels containing sauces &c. comprises a pump barrel 2 forming part of the cover 11 and carrying a suction pipe 3 and suction valve 4. The piston 5 is pressed upwards by a spring 6 and has an axial channel 2' controlled by a valve 7 and opening into a lateral discharge nozzle 8. Means are provided to prevent the piston from being pressed down while the vessel 1 is upright, and may comprise a ball 18 in an inclined slot 19 in the piston head, and a channel 21 which is blocked by the ball while the vessel is upright, thereby preventing a pin 20 carried by the barrel 2 from entering the channel 21 and locking the piston. The upward movement of the piston is limited by the head of a screw carried by the barrel engaging a slot in the piston head.
Patent GB-966454-A (GB)
Title: Improvements relating to clearable image-bearing opaque films
IPC: G03F1/90
Filed: 1963-02-28
Abstract: A process for the production of image-bearing films comprises (a) treating the surface of an opaque pressure-sensitive layer of an organic polymer having clear, dense image areas and porous opaque areas with an aqueous solution containing (1) a dye, (2) a surface active agent having wetting and detergent properties and (3) a water miscible organic liquid, (b) physically (mechanically) removing excess dye from the surface layer and (c) applying to the surface an aqueous solution of a dye-insolubilising agent until it has penetrated at least partly into the pores of the film and then optionally (d) wiping the surface to remove excess insolubilising agent.  The preferred polymer films are composed of vinyl polymers or copolymers having substantially uniform porosity with a pore size less than 1/2 micron and become transparent when subjected to pressures of, e.g. 10,000 lb./sq. inch.  The porous film is supported on a transparent, dimensionally stable film of, e.g. orientated polyethylene terephthalate.  The clear, dense image areas may be formed by pressure exerted by a relief, e.g. a halftone plate.  The dyes are preferably water-soluble, those specified being chromium complexes of acid azo dyes.  The water-miscible liquid is preferably an alkanol containing 1-4 carbon atoms and the surfactant may be anionic or non-ionic, e.g. the triethanolamine salt of mixed dodecyl and octadecenyl sulphate.  Steps (b) and (d) are preferably accomplished by wiping the surface with a soft rubber blade or with a soft tissue or cloth and/or by washing with water.  The insolubilising agent may be a quaternary salt of poly(b -diethylaminoethyl-methacrylate) or a metal salt, preferably of a polyvalent metal, e.g. aluminium sulphate.  Examples are given. Specifications 741,244, 741,441, 807,948 and 919,671 are referred to.

Abstract: 350,061. Horticultural knives. BOSCH, J., 11, Gang Scott, Weltevreden, Java, Dutch East Indies. March 15, 1930, No. 8459. [Class 30.] A knife for use in tapping rubber latex and like producing plants comprises a stem 2, the end of which is bent and slotted longitudinally at 4 to form a blade part and a tooth 3. The blade comprises a part 5 sharpened at 8 and inclined relative to the stem ; a part 6 sharpened at 8 and bent through 90‹ and a part 7 again bent through 90‹ so as to be parallel to the part 5. The part 6 has a guide ridge 10 and the part 7 a hook 9. In use the part 6 lies flat against the tree and the knife is drawn in the direction of the length of the ridge 10. The sharpened edge of the part 6 cuts into the tree to a depth determined by the pressure and by the tooth 3, and the cutting edge of the part 5 cuts off a strip of bark equal in width to the part 6. The ridge 10 is impressed into the softer inner part of the tree and acts as a guide, whilst the hook 9 prevents the knife being retained in the uncut bark. The sides of the part 6 converge from the cutting edge so that surface friction on the cut bark is reduced.

Abstract: 1414475 Measuring density UNITED KINGDOM ATOMIC ENERGY AUTHORITY 16 Feb 1973 [24 Feb 1972] 8696/72 Heading G1S To measure the density of a liquid, a constant flow of gas is supplied to a dip tube 1, the free end of which is immersed in the liquid, a float 5 also immersed in the liquid engaging in the end of the tube and restricting the gas flow therefrom to an extent depending on the density of the liquid, the difference in pressure between the gas in tube 1 and a datum pressure being a direct measure of the density of the liquid. The datum may be atmospheric pressure, in which case the free end of the tube 1 is only just immersed in the liquid under test, but may alternatively (as shown) be the pressure of a further flow of gas passing, at the same constant rate as the flow in tube 1, through a second, unobstructed dip tube 2 immersed in the liquid to substantially the same depth as the tube 1, a differential pressure measuring device 4 measuring the pressure difference between the gas in tubes 1 and 2.

Title: Improvements in or relating to iron-chromium-aluminium alloys and methods of making the same
IPC: C21C7/00
Filed: 1935-03-20
Abstract: An iron-chromium-aluminium alloy suitable for electric heating elements contains chromium in excess of 35,25 per cent, aluminium in excess of 5 per cent, the balance being substantially all iron; a preferred composition being 37 per cent chromium and 7 per cent aluminium.  0,5 per cent titanium acts as a grain refiner and 0,6 per cent silicon and 0,24 per cent manganese may be present.  Iron or mild steel is melted in a high-frequency induction furnace, and is deoxidized by calcium silicide, and the required amount of chromium is added in the form of ferro-chromium, after which further deoxidation takes place.  The bath is then covered with a slag free from boron or its compounds, and preferably consisting of equal parts of alumina and lime which is preheated to about 1500 DEG  F. before use, and remains under the slag until the latter takes up the calcium or other oxides present.  Aluminium chips, and, if required, a small amount of magnesium is added to deoxidize the slag, and return to the bath any iron or chromium oxides it may contain.  The slag is then removed and the required amount of aluminium added.  This may be done by pushing in an aluminium rod or wire which is melted below the surface of the bath.  A second slag addition is then placed over the bath, and further additions of alloys may be made before the slag is removed, and the melt poured, a pouring temperature of about 2900 DEG F. being suitable for obtaining an alloy for use in heating elements. Specification 454,127 is referred to.

In Figs. 1 and 2, a handle 10 has a metal fitting 12 with a spear 13, hook 14 and an open-ended arcuate groove slidably engaged by a flange 18 on a semicircular plate 19 provided with an eye 22 and a slot 21 and with stops 20, 20<1>, limiting movement of the plate. A lead rope 23 is attached to the eye 22 by a snap fastener 25. With the parts in the position shown in Fig. 1, the eye E of a mooring buoy B is engaged in the slot 21 and a pull is applied to the handle 10, the plate 19 moving relatively to the handle to the position shown in Fig. 2, pulling the end of the rope 23 through the eye E and finally releasing said eye ; the rope 23 and hawser 24 may then be pulled through the eye.

The ring flange 36 tapers outwardly at about 5 degrees. The lips 31, 32 may have the same or different diameters and have right-angled or sharp radiused sealing corners 44, 45 free from moulding flash. When installed between the outer and inner races 11, 12, of a ball-bearing, Fig. 2, the seal is pressed in an annular recess 21 in the stationary outer race so that a portion 37 of the ring 34 is located against a shoulder 22 on the race and the lips 31, 32 are deflected to sealingly engage both sides of an annular curved ridge 24 formed on the rotating inner race generally opposite the recess 21. The lips 31, 32 prevent respectively lubricant from escaping from and dirt from entering the bearing. The ring 34 and the member 40 are bonded together in a mould, Fig. 4, in which the ring is supported, except at its radial inner end, on a lower member 54 which co-operates with an upper member 55 and an annular outer member 58 supporting the flange 36 of the ring to define a cavity for moulding the member 40.
