Abstract: 423,231. Chenille. ZEHNDER, A., 27, Zurcherstrasse, Baden, Switzerland. Sept. 7, 1934, No. 25832. Convention date, Sept. 12, 1933. [Class 142 (iv)] [See also Group VIII] A braided cord having an irregular looped appearance due to the presence of unbraided threads 5, 6, which are caught in to form loops of varying size, is obtained by periodically varying the feed. The variation is produced by cams 17, 18 mounted on a shaft 15 below the braiding head. By setting the cams parallel or inclined to one another, different effects can be obtained, as shown in Figs. 6 and 7. The threads 5, 6 pass around rollers 30, 31, carried on arms 26, 24, the position of the rollers when free of the cams being regulated by screws 26a. The threads are drawn past the rollers 30, 31 by other rollers placed above the braiding point. The formation of loops is, however, periodically checked by the cams 17, 18 which cause rollers 30, 31 to have a braking effect on the threads 5, 6.

Title: A gas turbine aircraft engine coupled to drive a variable pitch propeller
IPC: B64C11/32
Filed: 1958-08-13
Abstract: 836,752. Propelling aircraft. GENERAL MOTORS CORPORATION. Aug. 13, 1958 [Nov. 22, 1957], No. 25989/58. Class 4. A gas turbine aircraft engine coupled to drive a variable pitch propeller, has mechanism which automatically causes feathering of the propeller on the application of reverse torque to the engine ; and a disabling device which renders this automatic feathering mechanism incapable of operating when a manual control is set to select reverse pitch of the propeller. A variable pitch propeller P mounted on a reduction gear assembly G is driven by a gas turbine engine E through a power shaft 10. The engine and propeller are controlled by a pilot's control lever 12 connected by linkage 13 to the input arm 14 of a co-ordinating control 16 which is connected by linkage 17 to an engine fuel control 18 and is also connected by a linkage 19, 21, bellcrank 22 and link 23 to an input control of the propeller. The propeller has two control rings 24, 26 mounted in a non-rotating part of the propeller hub and connected to the hydraulic pitch control mechanism within the propeller hub, the ring 24 having an arm connected to link 23 by which positive or negative pitch in fixed blade angle control, or speed governing operation, is selected, this condition being operated directly by lever 12 through control 16. The ring 26 has an arm 27 connected by a link 28 to a feathering control mechanism 30 which operates automatically in response to power or torque reversal between the propeller and the engine. In the preferred embodiment, Fig. 6 (not shown), such torque reversal is transmitted through co-operating helical splines, one connected to a fixed support and the other to the engine drive-shaft through the ring gear of an epicyclic reduction gear, so that upon reverse torque the ring gear performs axial movement and operates a plunger 51. When plunger. 51 moves forward it engages a rocker arm 52, pivotally mounted on pin 53, which arm bears on a rocker arm 54 mounted on shaft 55 provided, outside a housing 57, with a bellcrank 58, one arm of which is connected to link 28 and the other arm to a link 87 extending from a solenoid 85. Arm 54 is urged by a spring 92 into the position in which it does not transmit the feathering signal, this position being adjusted by a tappet 97. Consequently movement of plungers 51 results in rotation of shaft 55 and movement of arm 27 to feather the propeller blades, though such feathering may also be achieved by solenoid 85. In order that said feathering mechanism may be disabled when lever 12 is moved into the reverse thrust range, arm 52 has a recess 64 cut in its lower portion which may accommodate the full travel of plunger 51 when arm 52 is rotated about a shaft 61 by a solenoid actuator 78 operating through a linkage 76, 68 and 63, the solenoid 78 being energised through leads 80, 81 when a switch 82 is closed by a cam 83 on the lower end of lever 12.

Title: Improvements in or relating to control apparatus for internal combustion engine power units
IPC: F02B3/06
Filed: 1937-09-25
Abstract: 483,691. Regulating. SULZER FRERES SOC. ANON. Sept. 25, 1937, No. 26034. Convention date, Oct. 23, 1936. Addition to 456,119, [Group XXIX], [Class 7 (vi)] [Also in Group XXIX] In the internal-combustion engine power unit claimed in the parent Specification, the control of the fuel supply according to the supercharging pressure is effected through a member in the apparatus whereby the movements of a governor responsive to engine speed are transmitted to the member or members controlling the fuel pump. The engine 1 drives the governor 5, a main generator 2, and an auxiliary generator. 3 which supplies the field current for the main generator. This current is controlled by a resistance 19 so as to control the load on the engine. The movable arm 18 of the resistance is operated by a servomotor 17, the control valve 16 of which is connected by a rod 15 to a lever 7 movable with the governor sleeve 6. The supercharger 22 is driven by the exhaust gases, and the supercharging pressure generated in the manifold 23 is operative on a bellows 27 against a spring 28. The bellows 27 is connected to the pivot 36 of a bell-crank lever 37, the arms of which are in turn connected to the lever 7 and to a rod 12 which controls the fuel pump 13. When an overload occurs, the governor sleeve 6 falls, causing the fuel supply and the resistance 19 to increase so as to restore the speed to normal. A decrease in the supercharging pressure raises the pivot 36 and, by altering the effective length of the linkage 7, 37, 12, reduces the fuel supply. The engine speed then drops and the regulation proceeds as in the case of an overload. The contact of the governor weights with the sleeve 6 is relied on to limit the maximum quantity of fuel which can be injected when an overload occurs, but a stop for the lever 37 may be provided for this purpose. The governor setting is adjustable by a cam 33. In a modification the fuel pump also is controlled through a servomotor.
