Abstract: 1,082,852. Tubular collagen films. UNILEVER Ltd. June 15, 1965 [June 16, 1964; Sept. 8, 1964], Nos. 24892/64 and 36780/64. Heading B5B. A method for the preparation of tubular casing, comprises modifying collagen by treating it with a strong alkali in the presence of an alkali metal salt capable of preventing swelling of the collagen and subsequently extruding the modified collagen in tubular form. The strong alkali is suitably an alkali metal hydroxide capable of giving a solution having a pH of 13 or above, especially sodium hydroxide. The preferred alkali metal salt is sodium sulphate. Preferably, the salt is present in a solution more than 90% saturated with respect to the salt. Desirably, the modified collagen submitted to extrusion has a gelatin conversion determined as described in the Specification, of 10 to 22%, especially 10 to 17%. The modified collagen may be swollen with a carboxylic acid, especially a hydroxycarboxylic acid, prior to extrusion. To alter the drying characteristics of the casing, and make its moisture content more uniform, a suitable plasticizer or humectant may be added to the acid swollen material, for example, glycerol. The suspension of modified collagen extruded may contain from 2À5 to 10% by weight of total solids, especially 6 to 8%. The precipitating bath may contain an alkali metal salt or an ammonium salt capable of precipitating collagen, and a preferred precipitating bath contains sodium chloride, or sodium chloride and ammonium hydroxide. Suitably the sodium chloride is in saturated solution and the ammonium hydroxide not greater than seminormal, preferably deci-normal. The precipitating solution may also contain a tanning agent. After precipitation, the casing is washed with water containing a small proportion of ammonium hydroxide, and is air dried. In a modification, the precipitated casing is partially or substantially completely dried without previously washing out the precipitating salt. During and after drying, the casing is preferably maintained at a pH of not less than 5. The salt may be washed from the product after partial or complete drying.

Title: Improvements in or relating to oil burning apparatus
IPC: F23D11/18
Filed: 1937-09-14
Abstract: 502,111. Automatic control systems. MAY, T. L. Sept. 14, 1937, No. 25029. Convention date, Sept. 14,1936. [Class 38 (iv)] [Also in Groups XI and XVIII] Fluid pressure; fluid level.-In a thermostatically controlled liquid fuel burner apparatus, steam for atomizing the fuel is obtained from a steam generator 2 fitted with an electric heater comprising spaced electrode plates 15, 16 mounted on porcelain blocks 17, 13. Water is supplied to the steam generator through a coiled pipe 4 fitted with a manually adjusted valve 34 and a solenoid-operated valve 35. The generator is connected to the burner by a pipe 3 fitted with pressureoperated switches 27, 28, a solenoidoperated valve 29, and a manually adjusted valve 30. The fuel reservoir 5 is connected to the burner through a large conduit 40 and a reduced-section conduit 42 which is coiled around the generator 2 and is fitted with solenoid operated valves 44, 45 and a manually adjusted valve 46. The operation of the burner is controlled by a thermostat 78 responsive to the temperature of the medium heated by the burners. The electrical connections shown are for a single phase three conductor supply system. At starting all the solenoidoperated valves are closed, the pressureoperated switch 27 is closed and the pressureoperated switch 28 is open. When the control switch 60 is closed the solenoid-operated valve 35 opens to admit water to the steam generator 2. On the water level reaching the upper plate 15 the heating circuit for the water is completed through the water and a relay 65 which breaks the circuit to the valve 35, allowing it to close. Steam is then generated and when its pressure reaches a predetermined level, say 8 lbs. per square inch, the switch 28 closes. If now the thermostat is calling for heat a circuit is completed to open the steam valve 29 and fuel valves 44, 45 and also to supply current to the primary coil of an ignition transformer 75. If the pressure in the generator exceeds a predetermined level, say 11 lb. per square inch, the switch 27 opens thereby breaking the heating circuit until the pressure has fallen to a lower limit, say 8 lb. per square inch. Where the water level falls below the upper plate 15 the relay 65 becomes de-energized and the valve 35 is opened to admit more water to the generator. When the medium being heated reaches the desired temperature the thermostat 78 opens or, if the steam pressure diminishes below 3 lb. per square inch, the switch 28 opens, thereby closing the valves 29, 44, 45. In another apparatus the steam generator is fitted with an electrical immersion heater and the water is admitted to the generator through two float operated valves arranged in series.

Title: Vulcanizing mould for inner tubes and the like
IPC: B29D23/24
Filed: 1933-09-11
Abstract: 424,592. Pipe couplings. BRIDGE & CO., Ltd., D., Castleton Iron Works, Castleton, Lancashire.-(National Rubber Machinery Co. ; Akron, Ohio, U.S.A.) Sept. 11, 1933, No. 25055. [Class 99 (i)] [See also Groups V and XXIX] In the vulcanization of hollow rubber articles, fluid pressure is admitted to, and exhausted from, the article by means of a coupling capable of quick attachment and release, and carrying a floating member which makes a fluid-tight joint with the valve-stem on the admission of fluid pressure, and moves on the release of pressure to allow the article to exhaust to the atmosphere. A coupling 19 Fig. 2, connected to the end of a pressure hose 43 is adjustably mounted in the groove 48 of a slide 49, which itself is carried in a slot in a member 51 mounted on the mould, to allow the coupling to accommodate itself to valve stems 15 of various shapes and sizes. The valve stem 15 passes through an aperture in the mould, and is gripped by a bar 20 sliding in a recess 21 in the mould, and carried by a spring-urged member 25 pivoted at 26. The coupling 19 contains a floating member which on the admission of pressure, moves forward to make a tight joint with the valve stem 15, and on the release of pressure, moves back to allow the pressure to exhaust to the atmosphere through a port 44. Several forms of floating, member are described. As shown in Fig. 12 a sliding sleeve 65 has a nipple 66 for engaging the valve-stem 15, and contains a ball valve 69. On admission of pressure at 39<a>, the sleeve makes contact with the stem 15, and the valve 69 lifts. On release of pressure, the ball 69 closes, the sleeve is pushed back, and the article exhausts to the atmosphere through a port 44b. The admission of pressure may also cause the coupling to grip the valve stem. The sliding member may have projecting, resilient fingers, co-operating with a sloping shoulder on the body of the coupling, which forces them together as the slide moves forward. As shown in Fig. 10, admission of pressure at 61 moves a plug 60 to grip the stem 15, and bring ports 62, 64 into register. The slide 33<a> then moves forward to make a fluid-tight connection with the stem 15. On release of pressure, the slide 33<a> is blown back and is seated by a plug 35<a>, and the article is vented to the atmosphere by a port 44<a>. In another modification, the coupling is held on the valve stem by a manually operated spring grip.
