Title: Improvements in regulating means in power plants comprising at least one free-piston gas generator
IPC: F02B75/02
Filed: 1966-02-08
Abstract: 1,113,131. Combustion product power plant. SOCIETE D'ETUDES ET DE PARTICIPATIONS, EAU, GAZ ELECTRICITE, ENERGIE S. A. Feb. 8, 1966 [Feb. 9,- 1965], No.5504/66. Heading F1Q. [Also in Division G3] In a power plant comprising one or more freepiston gas generators A supplying the turbine 6 of an electric generating set B, the fuel injector 9 and exhaust valve 26 of the generator are normally controlled by a first control system which responds to the speed of the turbine, but this first control system is rendered inoperative by sudden large increases or decreases in the load on the turbine, such sudden increases or decreases causing maximum or minimum delivery, respectively, from the injector and maximum closure or opening of the valve 26. As shown, the said first control system comprises a governor 11 which establishes a pressure in line 12 proportional to the turbine speed, such pressure acting on pistons 15, 16 to control the injector 9 and exhaust valve 26 respectively. Piston 15 controls the injector via lever 19, the latter having cam surfaces 21, 22 co-operable with a stop 20 to define minimum and maximum Injection. The stop 20 is carried by a piston 23 responsive to the air pressure in casing 4. Any sudden increases in the load on the turbine are sensed by a regulator c comprising a watt-meter w and a differentiating R-C circuit Fig. 3 (not shown). The regulator closes a switch 28 to cause a valve 31 to shut off communication between line 12 and pistons 15, 16 and open communication between the pistons and a pressure-oil reservoir 34, the pistons thereby being displaced to cause maximum fuel injection and closure of the valve 26. Any sudden decreases in the load cause the regulator c to close a switch 29, thereby causing a valve 38 to shut off communication between line 12 and pistons 15, 16 and open communication between the pistons and an exhaust line 41. The pistons thus cause minimum fuel injection and opening at valve 26. Once either of switches 28, 29 has been closed, this switch remains closed for a period determined by the capacitance of a capacitor in the differentiating circuit, such period being dependent on the magnitude of the sudden change in load. In an alternative, sudden increases control only the injector while sudden decreases control only the valve 26.

Title: A method of, and apparatus for, feeding and changing of yarns in circular knitting machines
IPC: D04B15/58
Filed: 1955-03-01
Abstract: 804,434. Knitting-machines. ZAPADOMORAVSKE STROJIRNY NARODNI PODNIK. March 1, 1955 [March 1, 1954], No. 6050/55. Class 74 (2). Interchangeable yarn fingers 1-5 lie in a plane which is parallel to the axis of the needle cylinders, and their axes converge towards a point 11 which is that occupied by the eye of any yarn finger when active. Each finger is slotted longitudinally to engage a wire 30 common to them all and it can thus pivot about that wire and slide longitudinally in a corresponding groove in a housing 19, moving from an inoperative position I, through intermediate positions II, III, IV, to the feeding position V and vice versa. Fingers 1-4 supply striping yarn and finger 5 a reinforcing yarn for heel or toe. A striping finger is selected, for introduction, by a " drum " in the form of a right prism, each face of the prisms bearing holes which correspond in number to the striping yarn fingers and which may be occluded by plugs in accordance with pattern requirements. A pin 21 corresponding to a finger to be selected is prevented by such a plug from entering its hole, as the drum is swung towards the series of such pins, and therefore swings the finger into position II. A lever now swings clockwise, and a plate thereon advances the finger to position III. Thence, the finger moves into position IV and then, finally, when the drum retires, can swing, under the action of a spring 12 and a spring-urged plunger 22, into position V, where it is held by engagement of the plunger under a shoulder at the end of a recess 15. The plungers are controlled by a comb 27 which temporarily withdraws them, whilst the ingoing finger is in position IV, to release the outgoing finger and allow it to return to inactive position. The pin 21 of the reinforcing yarn feeder is advanced, when required, by a member which can be clutched to an operating member in place of the prismatic drum. The prismatic drum is normally racked round, to present a fresh prism face, between each two swings; but, in order that the same striping yarn may be used before and after the reinforcing yarn, means is provided to disable the racking mechanism in such case. Associated with the yarn trapper are two yarn cutters, outgoing yarns being cut between trapper and needles at two points, allowing the free yarn ends, which would otherwise be noticeable at the back of the fabric, to drop for removal; whilst the ends of ingoing yarns, which have been withdrawn from the trapper, are cut close to the needles. The racking of the prismatic drum, providing the sequence of yarn changes indicated by the chosen arrangement of plugs in the drum, is controlled by lugs on certain of the links of a pattern chain. Extra rackings of the drum, to vary the sequence, without having to re-arrange the plugs, are provided by additional links inserted in the chain and provided with the necessary lugs.
