Title: Improvements in or relating to hydraulically operated brakes
IPC: B64C25/44
Filed: 1932-09-15
Abstract: 407,677. Fluid - pressure brakes. PARNALL, G. G., and CLARKE, H. V., Coliseum Works, Park Row, Bristol. Sept. 15, 1932, No. 25642. [Class 103 (i).] A master cylinder for a hydraulic brake comprises a high pressure piston reciprocally mounted in the low pressure piston, the pistons being connected so that they move together until an initial braking effort has been exerted when the low pressure piston chamber is cut off and the high pressure piston alone acts. One modification comprises a high pressure piston 9, 10, Fig. 1, slidable within a low pressure piston 5, 6. The pistons move together when initially operated to force fluid into the pipe line 13 until the resistance is such that a spring 12 between the pistons is compressed and the piston 9 moves alone to give high pressure actuation closing the part 5<a> leading from the piston 6 to the brakes. Air is trapped in the upper part of the compartment 4b and acts as a cushion to prevent excessive braking. A part 9<a>, connects the space below the piston 9 to the space between the piston 9 and a flexible annulus 14 connecting pistons 6, 9. A passage 4d leads to a fluid reservoir. In another modification the high pressure piston 20, Fig. 2, and low pressure piston 23 are operated by a pivoted pedal 15 by means of a telescopic spring connection 17, 18 which prevents too violent application of the brakes. A link 22 connects the pedal pivot and the lower pivot of the connection 17, 18. The piston 23 forces fluid to the pipe line 30 by passages 27, 28 by raising a valve 31 slidable in the piston 20. When the resistance is such that a spring 26 between the pistons is compressed the piston 20 alone applies high pressure to the brakes, the pressure keeping the valve 31 closed. A washer 32 provides resistance to the movement of the valve stem 31<a>.

Title: Method of winding artificial silk on bobbins and thread-guide mechanism for carrying the method into effect
IPC: B65H54/32
Filed: 1933-09-18
Abstract: 408,874. Winding bobbins in artificial silk spinning-machines. SNIA-VISCOSA SOC. NAZIONALE INDUSTRIA APPLICAZIONI VISCOSA, 15, Via Alfieri, Turin, Italy. Sept. 18, 1933, No. 25811. Convention date, Sept. 30, 1932. [Class 120 (ii).] In artificial silk spinning- machines conical-ended bobbins are wound so that the ends merge by a rounded conformation with the cylindrical part by imparting tc the traverse guide two separate variations in ampli. tude, one being a slow decrease throughout the building of the bobbin and the other a frequent alternating very small increase and decrease. In the arrangement shown in Fig. 1, the reciprocation imparted by a traverse cam 2 is frequently varied by a cooperating cam 3 which is engaged by a fixed stop 33 so that the two cams move longitudinally, the variations being effected by driving the cams by a gear 4 through two wheels 21, 32 which have different numbers of teeth, for example in the ratio of 24 to 25, and are respectively secured to a shaft 1 which carries the cam 2 and to a sleeve 31 which carries the cam 3. The gradual reduction in amplitude is effected by varying the effective leverage of a transmission lever by means such as described in Specification 367,370. In the arrangement shown in Fig. 4, three cams 3, 5, 6 are employed, the traverse bar 8 being directly operated by the cam 5 and the amplitude of the reciprocation being frequently varied by the cam 3 and gradually reduced by the cam 6. The cams 3, 5 are freely mounted on a shaft 4 and respectively driven from a shaft 1 through gearing 12, 31 and gearing 11, 21, 22, and the cam 6 is keyed to the shaft 4 which is driven from a gear 23 through a differential motion, a gear 92 and a gear 93 provided with ratchet pawls 94. The gear 22 controls the planet carrier of the differential motion through change gear 24, 25 and worm gearing 100, 103. The cam 3 rotates at a speed appreciably different from that of the cam 5, say an advance or retardation of one revolution in every twenty-five, whereas the cam 6 rotates less than half of a revolution during the winding of the bobbin. The tracks of the cams 3, 6 are connected by projections 71, 72 on a slidable rod 7, the cams 5, 6 are fixed as regards longitudinal movement relative to the shaft 4, and the shaft 4 is slidable relatively to the cam 3, so that longitudinal movement of the shaft 4 and the cams 5, 6 is imparted by the cam 3, whereby frequent variations of the traverse transmitted by the cam 5 are effected, and a gradual reduction is effected by reason of the relative rotary movement of the cams 5, 6. At the completion of the winding, a cam 96, controlled by the bobbin-changing gear, operates a cone 97 and raises the pawls 94 and thus permits a spring 99, charged by the relative rotation of the cams 5, 6, to return the cam 6 to its original position in relation to the cam 5, such position being determined by the engagement of a tooth on a flange 42 with a stop 53 on the cam 5.

[Also in Division C6] Cells of micro-organisms are extracted with a solvent which consists of or contains formic acid, the extraction being carried out under conditions such that a substantial proportion of the nitrogenous content of the cells passes into the extract phase and such that a substantial proportion of the carbohydrate of the cells remains in solid phase, thereafter the extract phase is separated from the solid phase and the solvent is removed from the extract phase to obtain a solid extract containing both proteins and lower molecular weight nitrogenous compounds, and the solid extract is extracted with an aqueous medium of a pH at which a substantial proportion of the protein is insoluble in the aqueous medium, whereby nitrogenous compounds of lower molecular weight than the proteins are removed in the aqueous medium. The micro-organism cells are typically obtained by the aerobic culture of specified normal paraffin-consuming yeasts, moulds or bacteria on a hydrocarbon substrate. Under preferred conditions of operation: the micro-organism is in a dry state when subjected to the extraction, formic acid is employed in the anhydrous state or in aqueous dilution containing at least 80% of formic acid, and the extraction with formic acid is carried out at a temperature not higher than 60‹ C. with a contact time of at least 2 hours. The solid extract may be converted to a powder by milling, before the further extraction. According to the examples, dry Candida yeast was treated with 85% w./w. aqueous formic acid at 20‹ C. for 16 hours (or at 60‹ C.). The extract phase was subjected to vacuum distillation for the removal of formic acid, the dry residue, after an aqueous treatment at pH 4À5, was extracted at pH 12, and the pH of the extract was adjusted to pH 4, whereby the protein was precipitated.
