Abstract
Abstract A servo-controlled selection mechanism operating on pressure variations, for selecting one or more of a number of displaceable operating members preferably in the form of pins or rods and intended primarily for magnetic operation. The operating members are included in the shedding mechanisms of looms, in jacquard machines, knitting machines, card punching machines, or the like. The novel matter of the invention resides in that the actuators for each operating member comprises blocking means in the form of a body which is displaceable through pressure variations and which in one position prevents and in another position permits the operating member to be displaced, and in that a distributor including exchangeable channel blocks are provided between an impulse donor and a number of actuators, said channel blocks controlling the impulses from the impulse donor to the desired actuators mechanisms.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
260 words
A fluid impulse distribution system for use with textile machines such as looms and knitting machines, said distribution system comprising, in combination, an impulse donor adapted to sense information contained on a carrier and to supply pressure medium in response thereto, a plurality of actuators operable in response to impulse signals to control the setting of units in said textile machines, and an impulse distributor disposed between said donor and said actuator and operatively connected thereto to distribute impulses in the form of pressure medium flows from said donor to said actuators, blocking means in said actuators adapted to be displaced to control the setting of said units, said distributor including at least One pair of plates each provided with a plurality of parallel grooves formed in one side thereof and with the grooves of one of said plates being disposed at an angle with respect to the grooves of the other of said grooved plates, an intermediary plate disposed between the plates of each said pair of grooved plates, a plurality of apertures formed in said intermediary plate with each aperture connecting a groove in said one grooved plate with a groove in said other grooved plate, the grooves of each of said grooved plates being open toward said intermediary plates, conduit means operatively connecting the grooves of said one grooved plate to said donor and conduit means operatively connecting the grooves of said other grooved plate to said actuators so that pressure medium from said donor may be supplied to said actuators in accordance with the desired distribution.
Claim 2
Dependent Claim
260 words
A fluid impulse distribution system for use with textile machines such as looms and knitting machines, said distribution system comprising, in combination, an impulse donor adapted to sense information contained on a carrier and to supply pressure medium in response thereto, a plurality of actuators operable in response to impulse signals to control the setting of units in said textile machines, and an impulse distributor disposed between said donor and said actuator and operatively connected thereto to distribute impulses in the form of pressure medium flows from said donor to said actuators, blocking means in said actuators adapted to be displaced to control the setting of said units, said distributor including at least One pair of plates each provided with a plurality of parallel grooves formed in one side thereof and with the grooves of one of said plates being disposed at an angle with respect to the grooves of the other of said grooved plates, an intermediary plate disposed between the plates of each said pair of grooved plates, a plurality of apertures formed in said intermediary plate with each aperture connecting a groove in said one grooved plate with a groove in said other grooved plate, the grooves of each of said grooved plates being open toward said intermediary plates, conduit means operatively connecting the grooves of said one grooved plate to said donor and conduit means operatively connecting the grooves of said other grooved plate to said actuators so that pressure medium from said donor may be supplied to said actuators in accordance with the desired distribution.
Claim 3
Dependent Claim
47 words
A system according to claim 1 wherein the distributor is detachably provided between the donor and the actuators whereby a change in the distribution of the flow actuating the actuators may be affected either by substitution of another distributor or by installing different plates in said distributor.
Claim 4
Dependent Claim
17 words
A system according to claim 2, wherein the distributor comprises at least two pairs of grooved plates.
Claim 5
Dependent Claim
55 words
A system according to claim 1, further comprising coupling means by which one grooved plate of further pairs of grooved plates are connectable to said donor in sequence with said one grooved plate of said at least one pair of grooved plates whereby a plurality of duplicate impulse signals may be transmitted from said distributor.
Claim 6
Dependent Claim
75 words
A system according to claim 1, wherein said grooved plates are supported in assembled relation in a rigid holder and wherein said grooves in said grooved plates which are connectable with said donor and the actuators, respectively, correspond to apertures in surfaces of said holder and connected to lines from said donor and to said actuators, respectively, said plates being adapted to be urged against said surfaces to provide a sealing connection between complementary apertures.
Claim 7
Dependent Claim
43 words
A system according to claim 4, wherein said coupling means comprises apertures extending through opposed surfaces of connected plates whereby connection between successive grooved plates may be established by aligning the apertured surfaces and clamping the plates to form a fluid seal therebetween.
Claim 8
Dependent Claim
24 words
A system according to claim 1, wherein the intermediary plate is fixedly connected with one of the two plates it is adapted to separate.
Claim 9
Dependent Claim
71 words
A system according to claim 1, wherein said actuator is adapted to cooperate with a magnetic shed formation mechanism and comprises a moveable member displaceable between first and second positions by means of said pressure medium and said moveable member permitting movement of a pin of said shed formation mechanism when in said first position and blocking movement of said pin at least in one direction when in said second position.
Claim 10
Dependent Claim
93 words
A system according to claim 1, wherein said donor comprising a valve device including a chamber connectable to a pressure source, throughflow passages extending through one wall of said chamber and connected to said one grooved plate, and a slotlike recess provided in said one wall and intersecting said throughflow passages to receive said information carrier, said information carrier having apertures corresponding to the desired distribution to permit passage of pressure medium to the distributor via the channels represented by the apertures in said information carrier while preventing throughflow through the remaining passages.
