Patent GB-302735-A (GB)
Abstract: 302,735. Ba,stian-Morley Co., (Assignees of Lonergan, S. J., and Ginther, H. E.). May 28, 1927, [Convention date]. Divided on 291,076. Thermally-actuated valves. - A thermallyoperated valve controlling the supply of combustible medium to a burner has the valve closing member arranged below the seating and take-up means between the operating mechanism and the valve closing element so as to permit movement of the operating mechanism after the valve element has been seated. As shown, the take-up means consists of a spring 45. The valve member 22 is inserted in a pipe 15 supplying combustible medium to a burner 1 the thermal elements being arranged so that if the pilot flame 4a fails the supply to the burner is cut off. As illustrated the invention is applied to a water heater 8 in which the gas supplied to the burner 1 is controlled by a thermostat dependent upon the temperature of the water in the heater. The gas, after leaving the thermostat, not shown. is led through the pipe 15 to a casing 17 containing the ball valve 22. The latter is guided by ribs 50 on the casing 17 and is supported by the spring 45 from a lever 23<a> pivoted on a spindle 39' fixed to the casing 17. Another lever 28b is pivoted to the lever 23a and bears on an adjustable abutment 40. The pivot spindle 39<1> is protected from foreign materials in the gas by a baffle 51. One end of a non-expansible rod 24 bears in a depression in the lever 23<b> as described in Specification 263,734, [Class 64 (i), Heating liquids &c.], and other end 32 is fixed to an expansible tube 25 which is also secured to the casing 17 by a nut 29. The end 32 of the members 24, 25 which protrudes into the heater fire chamber 10<a> so that the pilot flame 4<a> plays upon it may have a guard as described in Specification 302,736 to pervent overheating of the parts. To prevent clogging of the valve 22 means described in Specification 291,076 may be used. In operation the valve 22 is always open while the pilot flame 4a is alight. Should the pilot flame fail, the resulting contraction of the tube 25 acts through the levers 23<a>, 23<b> to close the valve 22 and shut off the gas supply to the burner 1. Specification 302,736 also is referred to.

Abstract: 1383675 Blended polyester filaments KURARAY CO Ltd 29 June 1972 [30 June 1971] 30565/72 Heading B5B Blended polyester filaments having satisfactory binding properties and sufficient potential shrinkage difference between the filaments of the blend are made by heat treating simultaneously a blend of stretched polyester filaments having a higher shrinking percentage S 1  and stretched polyester filaments having a lower shrinking percentage S 2 , the values S 1  and S 2  satisfying the relationship: heat treatment being effected at a temperature of from 5‹ C. above the stretching temperature to 160‹ C. using a contact type heat treatment apparatus or at a temperature of from 20‹ C. above the stretching temperature to 190‹ C. using a non-contact type heat treatment apparatus (the said stretching temperature indicating the highest temperature on stretching) and the heat treatment being effected under a tension allowing the polyester filaments to shrink 1 to 5% based on the length of the stretched filaments, so that the shrinking percentage S<SP>1</SP> 1  of the former polyester filaments after heat treatment and the shrinking percentage S<SP>1</SP> 2  of the latter polyester filaments after heat treatment have the following relationship:  and, after cooling to an ambient temperature, winding them up, the said values S i , S 2 , S<SP>1</SP> 1  and S<SP>1</SP> 2  being measured under a tension of 5 mg. per denier and while dry heating at 170‹ C. Preferably the polyester filaments are made of polyethylene terephthalate or ethylene terephthalate copolymers containing not less than 80 mol per cent of ethylene terephthalate units. Where three or more kinds of polyester filaments are blended, the one having the highest shrinking percentage and the one having the lowest shrinking percentage are taken as "polyester filaments having a higher shrinking percentage" and "polyester filaments having a lower shrinking percentage" respectively. The blended polyester filaments may be obtained by separately spinning polyesters differing in their physical properties and winding the filaments up together preparatory to stretching and heat-treatment; or by taking polyesters which may or may not differ in their physical properties, separately spinning and winding the filaments and stretching them under different conditions preparatory to combining them for heat-treatment; or by spinning polyesters differing in their physical properties using a nozzle having a plurality of orifices through which they are separately extruded, and winding up the filaments together, stretching them and subjecting them to heat treatment. In the examples, stretching is effected at a draw ratio of 3-24 or 3À31 using a pin at 85‹ or 90‹ C. followed by a plate at 120‹ C. The filaments are then heat-treated on a plate at temperatures of 130‹ to 160‹ C. or using an airbath at 160‹ C. while they are held under tension such that then can shrink from 1 to 5%.

Title: Manufacture of dough and baked products
IPC: A21D8/04
Filed: 1952-12-05
Abstract: In making bread dough, a yeast-activated liquid is prepared by effecting fermentation of a yeast-nutrient liquid which contains yeast and a fermentable carbohydrate but is free from non-malted, natural starchy substances such as wheat flour and potato flour, and bringing about growth of the yeast in the liquid, and thereafter mixing the ingredients of the dough, including flour, with the yeast-activated liquid, the liquid containing sufficient ethanol and other products of fermentation and sufficient live yeast to allow the production, without long fermentation, of dough having essentially the properties, including flavour, of fermented dough.  According to an example of preparing the yeast-activated liquid, a mixture of 60 lb. of water, 1 lb. of commercial cornsteep liquor, 2,2 lb. of corn sugar, dibasic ammonium phosphate, potassium chloride, magnesium sulphate, calcium carbonate, sodium chloride, vitamin B1 and urea is seeded with 0,1 lb. of pure culture yeast and aerated at a rate beginning at 4 c.ft./min. and increasing with the yeast growth rate; after 16 hr. the aeration is stopped, 4 lb. of corn sugar is added, and the mixture is allowed to ferment for 2-5 hr. at 80 DEG F. According to a second example, similar procedure is adopted, the seeding being with 0,7 lb. or more of baker's yeast or active dry yeast and the yeast growth period being reduced to not more than 10 hr. The products of these examples contain 3-3,5 lb. of yeast and 3-6 per cent of ethanol.  According to a third example, yeast growth and fermentation are conducted at 80 DEG F. concurrently, a mixture of 60 lb. of water, 0,6 lb. of corn steep liquor, 6,25 lb. of corn sugar, ammonium sulphate, dibasic ammonium phosphate, potassium chloride, magnesium sulphate, calcium carbonate and vitamin B1, with 1,8 lb. of baker's yeast, being aerated at a constant rate of 0,4 c.ft./min. for 4-5 hr.  The product contains 3,6 lb. of yeast and 3,9 per cent of ethanol.  The liquids prepared according to the examples are used to make bread doughs with 100 lb. of flour, salt, sugar, shortening and, if desired, dried skim milk, and, preferably, an improving agent such as a mixture of potassium iodate and potassium bromate, the liquid providing the entire water content of the dough, and the dough produced on mixing these ingredients being divided and proofed in the usual manner.
