Abstract: 592,630. Reciprocating pumps. PARRISH, E. W. March 13, 1945, No. 6298. [Class 102 (i)] [Also in Groups XXVI and XXXVII] A device for stopping a mechanism, such as an engine driven pump, when a prescribed limit in a reversible operation, such as filling a petrol tarik, is reached, comprises a pair of two-way switches 6, 18 so connected in the engine ignition or other circuit that either can open or close the. circuit independently of the other; the switch 6 being automatically operated, e.g., by a float in the tank, to break the circuit and stop the engine when the tank is full, while the switch 18 is subsequently manually operated to remake the circuit to permit the engine to be restarted and emptying to commence. Switch 6, which may be a float operated mercury switch, is returned to its original position automatically during the emptying operation. An additional switch overriding the two-way switches may be provided, arranged to return to its non- overriding position after a predetermined lapse of time.

Filed: 1921-02-25
Abstract: 179,017. Juhlin, G. A., Kuyser, J. A., and Metropolitan-Vickers Electrical Co., Ltd. Feb. 25, 1921. Field magnets, dampers on polcs of.-Damping- circuits on the rotors of electric generators comprise slot-closing wedges of highly conducting material short-circuited at each end by a metal ring of good conductivity located within the end coil-retaining ring and provided with axiallyextending tongues inserted between the slot conductors and the slot wedges so as to be pressed into contact with the latter by centrifugal force. The tongued ring 10 may have the form of a complete circle, or two semicircles, and two such rings may be superposed. The portion 12 is placed inside the conical end ring 6, and the tongues 11, bent at 14 to conform with the shape of the end ring, are inserted under the slot wedges 4. The end ring, if of highly conducting material, such as bronze, may serve to carry part of the short-circuit current, but if of steel or other poor conductor, an additional ring of hard bronze or the like is provided between it and the slot wedges, contact between this additional ring and the tongues 11 being obtained by centrifugal force. The slot wedges extend a short distance beyond the core 1, thus leaving a narrow air gap between the end ring and the rotor body and increasing the magnetic reluctance of the path surrounding the damping copper in the end ring 6.

Abstract: 124,839. Dawson, Sir A. T., and Buckham, Sir G. T. June 2,1915. Ordnance breech mechanism.-Relates to firing- mechanism of the slip-look type comprising a rocking hammer with which engages a lanyard that becomes completely detached from the hammer as it is retracted to fire the gun. The invention consists in connecting the lanyard to a guard member on the hammer, which member is moved to liberate the lanyard as the hammer completes its rearward movement. Fig. 1 shows, in sectional plan, the invention applied to firing-mechanism of the primer-lock type. To fire the gun when the lock-frame B is in the closed position shown, the hammer C is moved rearwards about its pivot c against the action of a spring C<2> by a lanyard connected to a pivoted hook d'. When the member d<2> of the hook contacts with a fixed surface b<1>, the lanyard pulls away from the hammer, which is then impelled forwards by the spring C<2>.

A fibreless solution comprises cellulose, dimethyl sulphoxide, nitrogen dioxide and 0À2 to 1À0% by weight of water. The composition may comprise cellulose, 3 to 30% NO 2 , 0À2 to 1À0% water and the balance dimethyl sulphoxide, the ratio of the proportion of nitrogen dioxide to that of cellulose by weight in the mixture being within the range 1À7 to 2À3. The term " cellulose " is used in the specification to include cellulose itself, cellulose esters and cellulose ethers. The composition may comprise cellulose, 10 to 25% by weight of nitrogen dioxide, 0À2 to 1À0% by weight of water, and the balance dimethyl sulphoxide, the proportion of nitrogen dioxide to that of cellulose by weight being within the range 1À7 to 2À3. The solution may be formed by dissolving comminuted cellulose in a solution of 3 to 30% by weight of nitrogen dioxide in dimethyl sulphoxide, the cellulose and/or the solution of nitrogen dioxide in dimethyl sulphoxide containing such a proportion of water that the final solution contains 0À2 to 1À0% by weight of water.

Weft is inserted in a shed by clamping it some distance from its end and projecting it into the shed in the form of a loop one leg of which is stationary and the other of which "unwinds" to straighten. In Figure 5 weft 30 is clamped at 34, is projected into the shed by rapidly rotating rollers 32, 33 and is severed by shears 36 to enable a length to be laid in the shed. Continuous feed rolls 37, 38 and a suction storage tube 39 are provided. In Figs. 6 and 8 the weft is projected by a roller 44 on a link 49 moved by a torsion bar operated lever 48. Clamps 62 close on the projected weft, it is severed by shears 63 sucked into a storage tube 45 when delivered by continuously operating feed rolls 42, 43 and held at the far side of the shed by a suction tube 65. In Figs. 2 and 3 (not shown) the weft may be clamped. at 11 to the projecting lever 10 or, to increase speed of withdrawal from the suction tube, be clamped at 21 on the machine frame. In the main embodiment Figs. 21 to 25 (only Fig. 22 shown) weft 136 is held by a clamp C and projected from a suction tube 185 by a roller 150. During projection the continuously supplied weft is sucked into a tube 190, a clamp D closes on the stationary leg of the loop, the clamp C opens so that the loop from the tube 190 is drawn into the tube 185 (see also 'sleys' below), the weft is severed near the clamp D so that its free end is drawn into the tube around the roller 150 ready for the next pick. Weft inserters; operating. A cam 164 (Fig. 12) acts on linkage 165, 166 to straighten a toggle 158 and to move the lever 150 having the picking roller 150 against the action of the torsion bar.
