Abstract: 645,486. Knitting-machines. DEXDALE HOSIERY MILLS. Aug. 7, 1947, No. 21669. Convention date, Aug. 19, 1942. [Class 74 (ii)] The needles of a straight bar machine are of hook formation and have co-operating with them separate beard points interposed from above. The beard points 47 are carried on pivoted arms 50 carrying trunnions 51 entering bearings 52 in sliding plungers 53a. The plungers 53a, urged towards the needles by springs 62, operate in sleeves 54 which are swung about a shaft 56 by the action of a cam 60 on the cam-shaft 12 of the machine, the cam 60 oscillating an arm 58 attached to the shaft 56. The trunnions 51 carry spring-loaded stops 67 which engage segments 70 on the bearings 52 to maintain the arms 50 aligned with the plungers 53a. The stops 67 may be raised to allow the points 47 to be swung clear of the needles and the points are held in this position by the engagement of the stops 67 with notches 72 in the segment 70. The swinging clear of the points permits a dent to engage a gear connected to the machine camshaft to prevent the machine operating and pressing off the work. The points 47 close the needle hooks 45 during the drawing of a new loop through the old, in the manner of a normal beard and are accurately positioned relative to the needles by the engagement of rollers 76, on arms 75 attached to the plungers 53a, with cam surfaces 77 on the needle bar. During fashioning, cam surfaces 78 on the arms 42 of the fashioning point mechanism engage rollers on the trunnions 51 to slide the plungers 53a against the springs 62 to clear the points 47 from the needles and shogging of the camshaft causes the arm 58 to be actuated by a cam 80 during this period. The motion of needles, sinkers, knock-overs and fashioning points is as is normal in the art and an ordinary Cotton type machine may be adapted.

Title: Load sensitive device
IPC: B60T8/18
Filed: 1972-05-10
Abstract: 1395823 Load cell COMPAGNIE DES FREINS ET SIGNAUX WESTINGHOUSE 10 May 1972 [10 May 1971] 21840/72 Heading G1W [Also in Division F2] A load responsive device located between a sprung portion 1 of a vehicle and a suspension spring comprises a reaction piston 11 movable in a housing under a biasing means 12, a stress distribution device 31 transmitting a predetermined fraction of the load force between the sprung portion and the suspension spring to the opposite side of the piston, and a valve between a pressure source and a delivery chamber 18 operated by the piston to produce in the chamber 18 a fluid pressure control signal representative of the vehicle load and acting against the biasing force. As shown the biasing means 12 is a Bellville spring set by a screw cap 13 according to vehicle load and the device is of rubber or comprises a flexible container in which is sealed a hydraulic fluid or it comprises a system of levers. The valve device includes a member with a passage therethrough and a larger portion 28 slidable in the smallest diameter portion 25 of the stepped bore between a supply chamber 20 and exhaust chamber 23, a smaller portion extending axially towards a diaphragm 7 which acts as an exhaust valve seat 27 against which a valve member comprising the annular end of portion 26 may seat. The shoulder formed by the junction of parts 26, 28 serves as a supply valve operating with a washer type seat 21 secured in the bore by a snap ring 33. A passageway 35 provides connection to atmosphere to prevent damping action by piston 11. In operation chamber 20 is fully charged with' fluid under pressure from the source (not shown) and assuming that cap 13 has been adjusted for minimum load the spring 12 is initially effective in forcing piston 11 downwardly to close the exhaust valve but connect chamber 18 to chamber 20 to provide a maximum control signal to responsive apparatus connected to passage 19 to cause for example minimum brake application. If the load is increased the force acting on the piston 30 and hence on piston 11 is increased so that with movement of the piston the seat 27 is lifted off member 26 so that pressure in chamber 18 and consequently the control signal are reduced and braking pressure is increased. This arrangement is such that if the device connected to passage 19 fails or there is leakage maximum braking effort is provided.

Abstract: 1,018,965. Delivering sheets. JAGENBERGWERKE A.G. June 4, 1963 [June 29, 1962], No. 22139/63. Heading B6H. In a method of forming a stack of sheets from a stream of overlapping sheets, compressed air is applied to the underside of the stream to assist in separating the foremost sheet from the stream and depositing it on the stack and at the same time urge the remaining sheets against a conveyer disposed above the stream. The overlapping stream of sheets 2 is delivered from cutting or like apparatus by a plurality of spaced continuously moving belts 3, 4. The stream passes over a table 15 and a plurality of spaced rollers 10. As the trailing edge of the foremost sheet 1 clears the rollers 10 it falls away from the stream and the sheet is deposited on a stack 5. This movement is assisted by blasts of air issuing from nozzles 16 interspersed with the rollers 10, which in addition, provide a cushion of air to press the remainder of the overlapping stream of sheets against the belts 3. The rear wall 14 of the stack holder is provided with a jogging device 13 for aligning the sheets in the stack.
