Title: Fire extinguisher especially as a hand fire extinguisher
IPC: A62C13/74
Filed: 1971-04-19
Abstract: 1343209 Fire-extinguishers ELECTROPLASTIC VERTRIEBS GmbH 19 April 1971 [14 March 1970] 24276/71 Heading A5A [Also in Division F2]  A fire-extinguisher has a body (10) blowmoulded from thermoplastic plastics, and a head assembly (14) also of thermoplastics plastics screwed on to the neck (12) of the body. This head assembly has an annular concave recess on its underside, mating with the convex surface of the body, and concave sides which meet the concave recess at an acute angle at the outer edge. As shown, the body is made of polyethylene reinforced by glass fibres (11). The female screw thread 13, is of trapezoidal cross-section (Fig. 5) not shown, and the mating male thread is quadrant-shaped, so that a good seal is obtained by deformation of the threads, 23 is an annular seal. A tubular extension 25 of the head assembly has a pressure cartridge 26 screwed to its lower end and enclosed in the tube 29, also of plastics. Perforations 30 in the extension 25, allow extinguisher fluid to flow. An axial passage in the head assembly accommodates a striker 32, which is biassed upwards by a spring 40 bearing on a washer 39, but can be pressed downwards by a lever 37, pivoted at 36. Accidental operation is prevented by the insertion of a wedge between this lever and a groove in the top of the head assembly (Figs. 3, 4 and 5, not shown). When the striker is pressed downwards, it pierces the cartridge 26, releasing CO 2 , and also opens the valve 34, so that extinguisher fluid is forced out through the orifice 45. When the striker is released, the valve 34 closes again, and the extinguisher can thus be used repeatedly for a single filling. A mounting tray for the extinguisher is also described (Figs. 8, 9, 10 and 11 not shown).
Patent GB-443225-A (GB)
Title: Improved apparatus for indicating and/or controlling the level of glass in a tank
IPC: G01F23/24
Filed: 1934-08-23
Abstract: 443,225. Automatic control of fluid leveL PILKINGTON BROS., Ltd., Tower Building, Water Street, Liverpool, and BARNES, P. C., 249, Dentons Green Lane, St. Helens, Lancashire. Aug. 23, 1934, No. 24286. [Class 38 (iv)] [See also Groups XXXVIII and XII] In an apparatus for controlling the height of molten glass in a furnace, when an arm, which is moved towards the surface, makes contact an electric circuit is completed through the arm and the glass to stop movement of the arm towards the glass and to allow the arm to restore, an indicating pointer or control contact, moved with the arm, being left in indicating position until reset automatically. The contact arm is made hollow and is cooled by gases passing through the arm. The level of liquid is maintained by a displacer. As shown in the Figures, the tubular arm 1, cooled by air pumped into the arm at 9 and leaving at 10, is moved clockwise by a motor. The arm is provided with a heat resisting tip 7 and when this touches the surface of the glass, a circuit is completed for relay 69, Fig. 5, which allows .magnet 18 to energize and de-couple the arm from the driving motor, whereupon the arm is restored by counterweight 23. If the apparatus is used to maintain the liquid level constant, a contact arm 42, Fig. 4, is moved with the pointer 30 so that its end makes contact with conducting segment 36 or 37 or with the insulating central segment 38. In this arrangement a drum having conducting segments 64-67, Fig. 5, is driven by the arm driving motor, the segments being wiped by brushes 59-63. Whilst the contact arm 42 is being set, the brushes 59-63 are disconnected, but after the arm has been released, brushes 59-60 contact with segment 64, so that if arm 42 is in contact with either 36 or 37, one of the relays 54, 55 is energized. Motor 52 is started up to raise or lower the displacer 50 and clutch 40, 41 is energized to couple the contact arm 42 to the motor. When the arm 42 reaches the insulating section 38, the energized relay 54 or 55 falls away and the motor 52 stops. Brushes 59, 60, and 61 move off their segments and brushes 62 and 63 become effective to energize magnet 43 which moves the arm 42 and the indicating pointer 30 to the end position so that they can again be set by movement of the feeler arm 1. As shown, a two-pin clutch couples the arm 1 to the driving shaft 3 so that the arm is moved into the tank twice for each revolution of shaft 3, but the number of movements of the arm per revolution of shaft 3 may be altered by varying the number of pins on member 17 and holes in member 16. The level of the liquid may be regulated by means other than a displacer, such as by varying the height of a gate.

Patent GB-964913-A (GB)
Title: A method of chemically plating base layers with precious metals
IPC: C23C18/02
Filed: 1961-07-06
Abstract: Substrates are chemically plated with precious metals of the platinum group, i.e. Pt, Pd, Rh, Ir, Os and Ru, using their salt solutions in organic solvents in the presence of reducing agents, by heating in an alkaline atmosphere. The alkaline atmosphere is usually provided by ammonia but other gaseous bases such as amines may be used.  The reducing agent may be an organic reducing agent which is dissolved in the organic solvent or it may be in the form of a gas admixed with the alkaline-reacting gas, or preferably it may be a combination of both reducing means.  The treatment is conducted at a temperature below 500  DEG C., preferably at about 350  DEG C.  The precious metal salts are chlorides but may also be bromides or iodides. The organic solvent is isopropyl alcohol but may be acetone and/or other ketones and alcohols.  The reducing agent is linalsol, i.e. coriandrol but may be replaced by etherical oils such as anise oil, lavender oil, or bergamot oil. A base metal plate, particularly Ti, coated with precious metal to serve as an anode is preferably subjected to an after heat-treatment at 400-500  DEG C. for 4-150 hours optionally with the addition of ammonia to the furnace atmosphere.  Where the reducing agent is used in gaseous form, together with the alkaline-reacting gas, it may be towns' gas, methane, Co or H2. Cathodes having a core of stainless steel or nickel coated with precious metal may be made by this invention. Other substrates named are glass, tantalum, activated carbon, silica gel and other materials coated with precious metals for use as catalysts.  Titanium plates for treatment are degreased and then cleaned in concentrated HCl by connection to an A.C. source. Current is passed at a current density of 5 amps./dm.2 and at 1 volt for 1-60 minutes, e.g. 15 minutes. After the current is cut off the plates remain in the acid for 5 minutes, are then removed, washed and dried at 700  DEG C. The solution may be applied to the substrates by immersion or brushing.  A solution of a mixture of salts may be used so that after reduction an alloy is plated, e.g. 70% Pt 30% Ir, 70% Pt 30% Rh.

Patent GB-247944-A (GB)
Abstract: 247,944. Jena, E. Feb. 17, 1925, [Convention date]. Medicines for internal use; hypodermic injections. - Animal covering substances consisting chiefly of keratine, e.g. hair, wool, horn, feathers, and skins, are hydrolized by alkalis until they lose their morphological form and are transformed into a gelatinous dispersion, from which an acid product is isolated by addition of acid. A second product, of basic character, can be obtained by adding alkalis to the filtrate from the acid products. The products, which are purified by washing with water under pressure, have a cellactivating action on the organism and may be used for internal administration or for intravenous injections. In an example, feathers are heated with sodium carbonate solution until their grease is removed and their elasticity disappears. After washing, drying, and grinding, the mass is heated up to about 110‹ C. under pressure in an autoclave with caustic soda or sodium carbonate solution until a glue-like mass is produced. This mass is transferred to a container filled with water, and treated with an excess of hydrochloric or other acid. The acid product thus precipitated is purified by dissolving in ammonia or sodium carbonate, precipitating with hydrochloric acid, and washing with water, alcohol, and ether. The ammonium or sodium compound may be fractionally precipitated by absolute alcohol and used for injections. By addition of an excess of alkali to the first acid filtrate, the basic compound is obtained. In another example, starting with roehair or sheep's wool, the hydrolysis is effected by ammonia under pressure. The Specification, as open to inspection under Sect, 91 (3) (a) comprises also the hydrolysis of sheep's wool with caustic soda solution. This subject-matter does not appear in the Specification as accepted.

Abstract: 616,027. Locking rods; securing wheels on shafts. WALLACE, J. G. Aug. 21, 1946, No. 24867. [Classes 80 (ii) and 80 (iii)] [Also in Group XXV] In a locking device for securing an outer member to a cylindrical inner member sliding therein, the outer member carries a yieldable wedge extending around the inner member, and a ring or sleeve loosely mounted on the outer member carries a non-yielding wedge co-operating with the yielding wedge to force the latter to grip the inner member when the sleeve is rotated. The outer member 8, Fig. 1, which may be, for example, the lower part of the adjustable leg of a table, carries the wedge member 14, formed integrally therewith by cutting a slot 11, 13, and tapering to its free end 15. The sleeve 10, Fig. 2, carried loosely on the member 8, is formed with a rigid internal wedge 16 by slotting and welding the free end to the adjacent wall. In assembly, the end of the wedge 16 lies in the slot 11 of the inner member. A projection 20 on the member may engage the upper edge of the sleeve 10 to prevent upward movement, as shown in Fig. 3. On rotating the sleeve, the wedge 14 is forced against the inner member 9 sliding in the member 8 and the two members are locked together. A grip element of wood or other material may be secured to the sleeve. Fig. 6 shows the device used to secure a member 22, e.g. a pulley, to a shaft 24. The pulley is mounted on a tube 23 which is formed with a yieldable wedge at its end, and the sleeve 10 is formed with a rigid wedge.
