Title: Pneumatic control device for fuel injection pumps
IPC: F02D1/00
Filed: 1954-11-02
Abstract: 755,314. Suction governors. SATZGER, E. Nov. 2, 1954 [Dec. 28, 1953], No..31627/54. Class 57 [Also in Group XXVII] The piston or diaphragm 14 of a suctiontype governor actuates a fuel injection pump control rod 19 through a lever 18 pivoted at 17 and a stop 20, actuated by a cutoff lever 11 mounted on the pivotal axis 17, acts upon the lever 18 to cut off the fuel supply. The lever 18 is pivoted on the shaft 17 which is fixed to the lever 11 and carries the stop 20 which in the normal position of the lever 11 co-operates with a stop 21, carried by the lever 18, to limit the fullload fuel supply. The stop 21 is carried by a spring-loaded pin 22 slidable in the lever 18, the end 25 of the pin being formed to co-operate with a cam 27. On rotation of the lever 11 in the direction a, Fig. 3, the stop 20 contacts the stop 21 and the lever 18 is rotated to move the control rod 19 to cut off the fuel supply. Simultaneously, the end 25 of the pin 22 rides up the cam 27, whereby the pin 22 is forced upwards, Fig. 4, against the force of spring 24 to move the stop 21 out of line with the stop 20 so that the latter snaps into a recess 28 in the pin. When the lever 11 is returned to its normal position after the engine has stopped, the governor spring 15 keeps the recessed part 28 of the pin 22 in contact with the stop 20 so that the control rod 19 moves to a position beyond the normal fullload position so that excess fuel is supplied when the engine is restarted. After starting, the governor moves the lever 18 and pin 22 to the right, Fig. 3, whereby the pin 22 moves out of contact with the stop 20 and snaps back into its normal position in which the stop 21 is positioned in line with the stop 20 to limit the full-load supply.

Title: Improvements in or relating to a process of preshrinking tubular fabric and apparatus therefor
IPC: D06C21/00
Filed: 1958-10-03
Abstract: 887,618. Shrinking fabrics. L. & L. MANUFACTURING Inc. Oct. 3, 1958 [Oct. 9, 1957; May 29, 1958], No. 31652/58. Class 42 (1). [Also in Group XVI] Tubular knitted fabric is preshrunk by belts 10, 12, Fig. 1, which press opposite sides of the fabric against the sides of an internal stationary form 28 while the belts move at a relatively low speed, the fabric engaging the converging surfaces of the belts as they turn around rollers 14, 16 where the belts have a higher surface speed. The form comprises a thin, wide forward portion 30 lying between the straight portions of the belts, a thicker, narrower portion 32 rearward of the belts, and a joining portion 34. The peripheral dimension of the form is constant, so that the form causes no lateral stretching and permits no lateral contraction while the fabric is longitudinally shrunk by the belts. The portion 34 may be shaped to fit the contour of each belt or to contact the belt along a line only. The belts, which are wider than the form, are made of solid rubber with a stretchable outer portion and an inner portion which is cloth or wire reinforced. The coefficient of friction between the belts and the fabric is much greater than that between the fabric and form. The fabric is pre-steamed by boxes 56, 57; after shrinking the fabric may be passed between steam rolls 58, 60 and/or drying boxes 62, 64 prior to folding or rolling. In a modification, Fig. 9, fabric 84 is fed to belts 80, 82 as they pass around rollers 97, 98; the degree of shrinkage is controlled by adjustment of the extent of turn of the belts around these rollers; this adjustment being effected by turning a handle 130 to vary the positions of rollers 100, 101 along contoured surfaces of control elements 109. The internal form 85 extends only part way along belts 80, 82 which are perforated and enclosed in an oven 83 whereby the fabric, presteamed by boxes 86, 87, is dried as it passes between the belts and can be wound into a roll 160 on a core guided in grooves 162 in a member 164. The inclination of member 164 is adjustable so that the roll 160 can, if desired, be driven by the turn of belt 82 at a higher peripheral speed than the straight portion of the belt so as to impart a slight stretch to the fabric to compensate for over-shrinkage.

Title: Improvements in multi-nozzle fuel delivery system
Inventor: HEMSWORTH MARTIN CARL
IPC: F02C7/232
Filed: 1966-07-14
Abstract: 1,106,597. Gas turbine engine fuel systems. GENERAL ELECTRIC CO. July 14, 1966 [Nov. 19, 1965], No. 31704/66. Heading F1G. [Also in Division F4] The invention relates to a multiple nozzle fuel delivery system for a gas turbine engine, each nozzle being connected to a fuel manifold and comprising a low-rate fuel discharge means and a high-rate fuel discharge means, there being means for switching from the high-rate means to the low-rate means, and further means is provided for automatically distributing fuel from any one nozzle to a plurality of other fuel nozzles in the event that any given nozzle should fail to switch from the high-rate discharge means to the low-rate discharge means. The invention is described with reference to a gas turbine engine which comprises annular combustion equipment to which fuel is supplied through a plurality of injector nozzles 14 which are connected through lines 24 to a ring manifold 20, Figs. 1 and 2 (not shown). Each nozzle comprises a low-rate discharge nozzle 34 and a high-rate discharge nozzle 48. When the fuel is at low-pressure it passes through line 24 into the nozzle body 26 through the filter and thence through duct 32 to low-rate discharge nozzle 34. As the pressure of the fuel supply is increased, so the pressure acts to move the valve member 38 downwardly against the action of the spring 36 until the valve ports 44 become aligned with the ports 42 in the inner casing 40. The fuel now passes also through the passage 46 to the high-rate discharge nozzle 48. The passage 46 of each nozzle is connected through a filter and passage 54 and line 50 to the passages 46 of the adjacent fuel injectors. Thus in the event that the valve member of one of the injector nozzles should fail to return to its upper position when the fuel supply is reduced, the fuel still passing into the passage 46 of the faulty nozzle passes also to the adjacent nozzles whereby the thermal loading of the combustion equipment is not concentrated at one point.

[Class 92 (ii)] The invention of the parent Specification is now modified by providing means for retaining the spring-loaded part of the buffer for the breech-block carrier in the compressed position until the next round is fired. In the construction shown the gas cylinder 3 constitutes the buffer, being urged rearwards by a spring 4 and having its front end frictionally engaging a split-ring 10 whose conical inner surface cooperates with a conical surface on the gasblock 2. When the breech-block carrier 20 strikes the cylinder 3 the latter moves forwards taking ring 10 with it until the ring meets the block 2 as shown, the ring then being held and the cylinder continuing its motion, compressing spring 4. Spring 4 then reverses the motion and ring 10 is frictionally carried rearwards by the cylinder until it is opened out by the conical surface on the block 2 when it is arrested and by friction holds the cylinder until the next shot is fired. The firing of a shot enables the gas pressure to force the ring forwards to release its grip on the cylinder. In modifications the conical surfaces are dispensed with and the split ring is adapted to enter grooves at certain points during the relative movements of the cylinder and gas-block, gas being admitted to the base of the grooves when a shot is fired to effect release.
