[Class 102 (i)] [Also in Group XXVII] In a variable-speed engine operating with injection of liquid fuel, and having a speed governor whereby the time of the commencement of injection is made earlier as the engine speed increases, means are provided for causing the injection to take place earlier when the engine is cold than when it warms up, for any given speed. A centrifugal governor 21 is connected by its sleeve 25 and lever 54 to the control rod 13 of the fuel pump 11, the sleeve 25 being splined at 26 to an inner sleeve connected to the driving shaft 12 through helical splines 33. The sleeve 27 is connected by a rod 37 to a thermostat or hand control, so that when the engine is cold, the sleeve 27 is displaced towards the left as shown in Fig. 3, whereby the timing of the shaft 12 and of the injection is advanced by means of the behind splines 33. As the engine warms up, the sleeve 27 is moved to the right until a stop 29 thereon comes against the end of the sleeve 25. Accelerator control of the fuel acts on the rod 13 through a lever 14, a spring 48 being interposed in the rod 13. The governor at first operates against the actions of springs 22, 30, a further spring coming into action at higher speeds. In a modification, the two sleeves 25, 27 may be formed integrally.

Patent GB-410745-A (GB)
Title: Improvements in the manufacture of spun yarns from continuous filaments
IPC: D01G1/08
Filed: 1932-11-12
Abstract: 410,745. Stapling continuous filaments by drawing. DREYFUS, H., 22, Hanover Square, London. Nov. 12, 1932, No. 32030. [Class 120 (iii).] Staple fibres are produced from continuous filaments by rendering the filaments temporarily brittle by cooling, and breaking them into short lengths whilst in that state, whereby breakage is effected without impairing the extensibility of the filaments. The cooling, e.g. to -5‹ C., may be effected by passing cooled brine or liquid air through a hollow roller with which the filaments contact. The breaking may be performed continuously with drawing, so that the continuity of the bundle is preserved ; twisting may also be effected in the same operation. A false twist may be imparted to the fibres, and a device may be provided for supporting the bundle between successive pairs of drawing rollers, e.g. an endless band. Several filamentary bundles may be led side by side, and may be doubled if desired. Filamentary bundles 5 from bobbins 6 pass through guides 7, over the hollow roller 10 through which a refrigerant is passed. The temporarily brittle filaments are then broken by drawing between the rollers 19, 20 and 21, 22, and the sliver twisted, with or without further drawing, by the flyers 9, or by a ring device. The filaments may be moistened by passing over wicks 26 before cooling, so that the moisture freezes and causes greater brittleness. The brittleness is preferably removed immediately after the drawing operation by jets of hot air. According to the Provisional Specification, roughening media, e.g. kieselguhr, talc, pumice, carborundum or emery, or soluble roughening media, e.g. such as described in Specification 372,797 may be applied to or incorporated in the filaments, preferably before breaking, and hygroscopic media, e.g. those described in Specification 387,003 may also be applied.

Abstract: 1,039,837. Valves; compressed air brakes. WAGNER ELECTRIC CORPORATION. Aug. 10, 1964 [Oct. 25, 1963], No. 32531/64. Headings F2F and F2V. A valve for controlling the application of fluid pressure from a pair of sources 4, 10, Fig. 1, to a pair of fluid pressure motors 8, 13, such as the brake cylinders of a vehicle, comprises a housing 18, 19, 20, a pair of flow passages 27, 28 and 53, 54 for respective connection between the sources and the motors, a pair of valves 33, 59 normally urged to positions interrupting flow through the passages, a pair of valve actuating members 40, 66 slidable in the housing, a resilient connection 78 between the actuating members to apply a pre-loading force to the actuating member 66 when the actuating member 40 approaches the valve 33, an expansible chamber 74 between the member 66 and the housing, and a passage 75, 76 between the chamber 74 and the outlet port of the passage 27, 28 whereby opening of the valve 33 causes opening of the valve 59 by fluid pressure in the chamber 74 and by the preloading force. When a manual force is applied to the member 40 through a spring-loaded plate 47, a seat 42 engages the valve member 33 to disconnect the outlet port 28 from a vent 30 and to separate the valve member from a seat 39 connecting the outlet port to the inlet port 27. Outlet pressure acts through the passage 75, 76 on the member 66 to cause the valve 59 to disconnect outlet port 54 from a vent 57 and to connect it with inlet port 53. The pre-loading force of the spring 78 compensates for the pressure differential between the two flow passages in the valve to provide simultaneous opening. In Fig. 5, a lostmotion connection is provided between a sleeve 111 and a link 104 to permit mechanical actuation of the valve 59 in the event of a pressure failure in the passage controlled by the valve 33. The sleeve may abut the member 66 instead of the member 40 or it may be dispensed with and the lost-motion between a flange on the link and either of the actuating members 40 or 66 be accommodated by a spring mounted in one of the actuating members. The spring 46 provides " feel " and the member 66 may have effective upper and lower areas of differing size to reduce the pressure differential between the two passages as the valve opens.
