Abstract: 724,233. Pistons; cylinders. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 9, 1953 [July 18, 1952], No. 18233/52. Addition to 693,374. Class 122 (1). [Also in Groups XXIX and XXXI] In a modification of the invention of the parent Specification the operation of the sleeveretaining catches is effected by regulating the pressure in the cylinder on the exhaust stroke of the piston therein. In the arrangement shown, each sleeve-retaining catch is formed by a resilient split ring 2 which, when the hydraulic pressure in the cylinder a is not less than a predetermined figure, say 12 pounds per square inch, fits in a groove 1 in the cylinder and flush with the wall thereof. A corresponding groove 3 is provided in a sleeve o surrounding the piston g so that when the pressure is for example substantially below 12 pounds per square inch the ring 2 engages the groove 3 to lock the sleeve to the cylinder a. A port 4 in the sleeve o is provided with a valve 6 permitting free flow of liquid from the groove 3 and a restricted flow in the opposite direction. A chamfer on the lower edge 5 of the ring 2 allows the ring to disengage the sleeve by hydraulic pressure applied through the valve 6. In another arrangement, Fig. 3 (not shown), for more than two speed ranges, separate pressure-operated catches are provided between adjacent sleeves and between the cylinder and outer sleeve.

Filed: 1972-04-20
Abstract: 1331895 Servicing unit for spinning frames LEESONA CORP 20 April 1972 [30 April 1971 (2)] 18260/72 Headings D1D and D1F A servicing unit 26 for a spinning frame or frames having a plurality of spinning stations 16 disposed in opposite banks 14 is arranged to patrol in a continuous path first along one bank and then back along the other. A tractor 28 which traverses back and forth along rails 30 carries the unit 26 which swings from one side of the frame to the other at the ends of the traverse. The swinging is initiated when the tractor strikes the buffers 47 and is effected by a piston operated rack 96 and chain drive 108, Fig. 4. The unit is locked in its traverse positions by a lock 90 operating on a fixed bar 116. Activating Sensors, Fig. 6, the servicing unit 26 has four sets of photoelectric sensors 160 and light sources 162. The sensor 166 indicates when an arm 174 is lowered which occurs at stations where piecing has been attempted but has failed and hence prevents the unit stopping. The sensor 178 detects a yarn breakage, the sensor 180 detects a full package and the sensor 182 aligns the unit with a station to be serviced. Donning and Doffing is initiated by sensor 180. The servicing unit collects via a door 56 empty bobbins from a conveyor system 220, 222, 224, 226 which also removes full bobbins. The donning and doffing is by known means. Supplying and Collecting Bobbins. Empty bobbins 48 are stored in a hopper 188 from which they are oriented and placed on rotating declining rods 190 with an escapement 192 which deposits bobbins 48 onto a supply route 196 on the conveyor system 220, 222, 224, 226 when a gap is sensed by a sensor 193. The same conveyor system carries full bobbins by a route 228 to a receptacle 234. Stop motion, Fig. 6. If piecing at a given station fails after two attempts a roving breaker 168 is pivoted downwards by a jet nozzle 172 on the tender 26 for the pins 174 to engage and break the roving. Such action is sensed by sensor 166 so that the tender does not subsequently stop at these stations until they receive attention by an attendant, this is as shown also in Specification 1282041. The unit is powered by fluid motors and piston units and the control circuits are illustrated in Figs. 5 and 7 (not shown). Specification 1181521 is referred to

June 25, 1931, No. 18403. [Class 92 (ii).] A sighting telescope, which enables the lead angle to be applied to guns firing at moving aerial targets to correct for the target speed, has a parallel beam of light from a source 12 directed upon a pivoted diaphragm 9 provided with one or more transparent circular lines 9a, the angle of incidence varying as the telescope is directed on the target so that one or more luminous ellipses appear in the field of view. The ellipses appear on a ground-glass screen 8 and are reflected into the field of the eyepiece 2 by an inclined transparent reflector 6. The diaphragm, which is shaped to screen lateral rays, is connected to a shaft 10 movable in bearings under the control of a pendulum and an oil dashpot 14. The target is sighted, by actuating the gun-laying mechanism, until it appears to be moving towards the centre of the ellipses and is on that ellipse the major axis of which corresponds to the estimated speed of the target. An adjustable lens system may be inserted between the diaphragm and the screen 8 to enable the size of the ellipse to be varied to suit the estimated target speed. The reflector 6 is mounted on a rotary plate for alternate use with others of different transparencies.
