Title: Improvements in stop motions for spinning, doubling or twisting machines
IPC: D01H13/18
Filed: 1931-10-29
Abstract: 373,534. Delivery-stopping apparatus. WILD, M., Cottonificio Somaini, Lomazzo, Como, Italy. Oct. 29, 1931, No. 30040. Convention date, Nov. 7, 1930. Addition to 356,364. [Class 120 (ii).] In a stopping device for spinning, doubling and twisting frames for yarns according to the parent Specification, wherein the thread is driven between two superposed cylinders and in the case of thread breakage a falling arm sets tongues between the driving and driven cylinders, the tongues are secured to a rotatably mounted member which carries a member over which the thread passes. The thread F passes from a spool d round cylinders b, a over a bar e to its point of use. To the bearing 8 of the cylinder a is adjustably secured by a screw 12, a holder 11, on which an arm 1 is rotatably mounted by means of a pin 2. The arm 1 carries at its lower end a pin 15 on which is rotatably mounted a sleeve 3 with tongues 4 of leather, celluloid, rubber or like material. To the lever 3 is connected a small lever arm 9 carrying a wire loop 10. The movement of the lever arm 9 is limited in one direction by an extension of the pin 2. The thread F passes over the loop 10 and under the sleeve 3 so that if the machine is stopped the thread tension diminishes and the tongues 4 approach the driving cylinder b. Before, however, they contact with the cylinder b, the bent end of the small lever arm 9 does so, thus moving the loop 10 away from the cylinder a and increasing the thread tension so that the tongues 4 only contact with the cylinder b when this has nearly come to rest and accordingly are not engaged between the cylinders b, a. If, however, the thread breaks or the traveller or spindle drive is stopped the tongues 4 fall on the still moving cylinder b and are dragged between the cylinders b, a thus separating them and stopping the drive for the thread.

Title: Improvements in or relating to apparatus for making a chart or record appertaining to the operation of applying paint or the like
IPC: G01N33/32
Filed: 1949-11-29
Abstract: 672,750. Testing physical qualities; recording-apparatus. KEENAN, H. W. Nov. 16, 1950 [Nov. 29, 1949], No. 30522/49. Classes 106 (ii) and 106 (iv). Apparatus for making a record appertaining to the operation of applying paint to a preselected surface to give information about " wet-edge time" and " brushability" comprises a work-table tor supporting a test-piece to be painted and free to reciprocate, means for supporting and traversing a record strip and a pen for marking the chart in operative connection with the worktable. A sheet of material to which paint is to be applied manually by brushing is clamped to removable extensions 17, Fig. 1, of a work-table 12 by clamps 18 adjustable in slots. The work-table 12 is supported by depending members 13 linked to brackets 15 fixed on the upper part of a frame 10 so that it can reciprocate under the control of a system of springs 16. Recording mechanism is housed in a drawer 11 within the frame 10 and comprises a record strip drawn from a supply roll 23, Figs. 3, 4, over a platform 28, which may be upwardly sprung between a heavy idler roller 25 and a friction-feed roller 24 driven by an electric motor 26 at high speed or low speed through gear 30 or 31 meshing with gear 32 or 33 according to the position of a clutch device 35 controlled by a yoke 38 as set by a hand knob 36 and shaft 37 and indicated by lights 47, a neutral position of rest lying between. The record strip is marked by a pen 42, which may be of ball type, carried by an arm 39 pivoted on a bracket 40 and forked to embrace a member 44 depending from the work-table 12 so that when paint is brushed on to the test-piece causing the work-table to reciprocate to an extent depending on the " brushability" of the paint the pen makes strokes of corresponding amplitude and describes a graph against a time base on the record strip running at high speed. To conserve paper during interim periods between one application of paint and another, the paper feed is reduced to low speed and by varying these periods the maximum possible rest period possible without incurring an unsightly line, i.e. the " wet-edge time may be read from the record strip. A cam 45 on the shaft 37 lifts the pen from the paper through a hinged bracket 46 during rest and slow running periods. After use the record strip is curled by a guide 48 and may be cut off by depressing a handle 50 to operate a hinged cutter 49. An additional pen or pens may be adapted to inscribe longitudinal reference lines on the paper.

Title: Improved process for the preparation of a light hydrocarbon oil freed or substantially freed from mercaptans
Inventor: BERGEN RUDOLF HERMAN BLOEM
IPC: C10G19/04
Filed: 1962-08-10
Abstract: Light hydrocarbon oils containing mercaptans are freed of mercaptans by treating them in the presence of oxygen with an aqueous solution containing more than 20% wt. of free alkali metal hydroxide and containing diethylene glycol, preferably in an amount of 5-35% wt., as an auxiliary substance to increase the extractive power of the alkali metal hydroxide solution for mercaptans, but with no added components which would form salts with the alkali-metal hydroxide. The preferred alkali metal is potassium.  If desired, part of the diethylene glycol may be replaced by triethylene glycol, for example up to 50% vol.  The oil may be pretreated with an aqueous caustic alkali solution in the absence or presence of oxygen or an oxygen containing gas. Thus, a gasoline may be separated into a high-boiling and a low-boiling fraction, the high boiling fraction being treated with fresh caustic, which is then used for washing the low boiling fraction. In a modification of the above the fresh caustic is introduced into the second washing stage of the low-boiling fraction, and is then passed successively through the second and first washing stages of the high boiling fraction, and finally to the first washing stage of the low-boiling fraction.
