Abstract: 837,492. Cigarette lighters. NEWMAN,. S. H. June 14, 1957 [June 29, 1956], No. 18795/57. Class 75(3) The removable cover or head unit of a lighter incorporates the igniter mechanism and actuating means for a gas release valve, and is insertable into the open top of the case so as to limit the valve actuation spring devices latching it in the correct position. Fig. 2 shows an opentop casing 1 containing a liquefied gaseous fuel tank 2 which can be ejected by inserting a coin or tool through an aperture 5 in the bottom of the casing 1. Telescopically fitted in the top of the casing and releasably retained in position therein by a catch lug 72 is a frame 15 carrying the friction-wheel-and-flint ignition mechanism, the snuffer cap 22, and the finger lever 17 for operating the ignition mechanism and effecting the opening of the gas-release valve of the burner; the catch lug 72 is spring-urged into its latching hole 71 by spring arms 79 at the opposite end of the frame 15 bearing against the wall of the casing 1, or against the valve housing 10 of the fuel tank. A spring 50 for the finger lever 17 also acts on a lever 45/ 41 to press the flint 34 against the friction wheel. The gas-release valve is opened by the forked end of a bent blade spring 60 which fulcrums on the extensions 86 by which the latch spring is supported on the frame 15 when the forked end which has lateral lugs lying under the snuffer cap is permitted to rise by the snuffer cap being opened; the other end of the bent blade spring bears on the finger piece whereby the blade spring is additionally tensioned when the lighter is operated. Release of a flint is effected by swinging the lever 45/41 so that the end 41 lies laterally of the flint tube 33, this being conveniently done by means of a finger piece 55 pivoted at 56 on the Jever 45 but normally lying against the same.

Title: Improvements in cloth measuring and cost computing machines
IPC: G01B5/04
Filed: 1922-07-10
Abstract: 208,183. Tillman, F. J. July 10, 1922. Measuring.-A cloth-measuring machine of the type in which the cloth is pulled between a measuring-roller 20, Fig. 1, and grip-rollers so as to actuate a pointer 44 moving over a lengthscale 6, is provided with a unit-price scale 7 and a total-price chart 10 arranged parallel to the length-scale 6, the length-pointer 44 being positioned between the length-scale of the total-price scale so as to indicate simultaneously the length measured and the price therefor. In the form shown in sectional elevation in Fig. 2 the pointer 44 is fixed to a carriage 43 which is traversed by a screw 18 on the spindle of the measuring-roller. A second carriage 51 slidable on rods 52, 47 carries a pointer 59 which can be set by hand to the desired length on the scale 6. When the material is pulled through, the roller 20 is automatically stopped when the cam 58 on the carriage 43 engages a lever 55 on the carriage 51 and rocks a lever 53, Fig. 4, against a stop 60. The material can then be cut by a pivoted knife 94, a pin 103 on which engages a lever 104 and a vertically slidable bar 108 to rock a lever 64 having a projection 100 engaging a slot in the roller 20. The lever 64 has also a pin 71 engaging a pivoted member 73 which by contact with a pin 76 prevents a lever 90 being raised to release the griprollers 88. The material can therefore only be cut and released when the measuring-roller has been stopped in the correct position. To prevent the rollers 88 being depressed to remove the material after measuring and before cutting, a lever 132 engages a pin 138 on the member 73 but is released by a pin 135 on the member 108. The grip-rollers 88 are pivoted about two axes at right angles at the end of a lever 80 which is rocked to lower the rollers against the action of a spring 89 when the lever 90 is raised about its pivot 78. The total-price scale is in the form of a chart carried over rollers 9, 12, the rollers 12 being geared together by a spur-wheel 15 operated by a knob 17. The chart, can be locked by a catch 129 engaging the teeth of the wheel 15. As shown in Fig. 8, the measuring-roller is in the form of segments 21 which are movable radially to expand or contract the roller by longitudinally adjustable cones 28, 29.

Title: Improvements in and relating to the production of fatty acid esters from starch factory by-products
IPC: C11C3/00
Filed: 1938-06-29
Abstract: 516,493. Carbohydrate esters of fatty acids. CORN PRODUCTS REFINING CO. June 29, 1938, No. 19355. Convention date, Aug. 14, 1937. [Class 2 (iii)] Carbohydrate fatty acid esters are made from the waste products of a starch factory by extracting fatty acids from residues containing them, such as refinery mud or acidulated soap stock, converting the acids, to anhydrides or chlorides, and reacting the latter in solution with a sugar-containing starch conversion product, e.g., starch hydrol, in the presence of an acid-removing catalyst, e.g., pyridine, and finally removing the solvents. The products may be used as a fat or emulsifying agent. The crude fatty acids are converted into their anhydrides or chlorides by treatment with acetic anhydride or with thionyl chloride, or with phosphorus pentachloride, trichloride or oxychloride. In an example, refinery mud is extracted with methanol, the crude fatty acids are converted into a mixture of chlorides and anhydrides by reaction with thionyl chloride, the product is dissolved in chloroform, and heated under reflux with a solution of hydrol in pyridine ; the pyridine is then removed by washing with hydrochloric acid and the esters are obtained by distilling off the chloroform.
