Abstract: 695,525. Fluid-pressure servomotor-control systems. EUREKA WILLIAMS CORPORATION. Oct. 9, 1951 [Oct. 28, 1950; Nov. 13, 1950; June 28, 1951; Aug. 7, 1951], No. 23461/51. Class 135 [Also in Group XI] An oil burner of the low pressure type comprises a nozzle 18 for discharging atomized oil into a stream of secondary air flowing through a conduit 20 past the nozzle 18 which has restricted converging oil and air passages 34, 30 to which oil and air is supplied through connections 46, 60 connected, respectively, to a body of oil in a reservoir 10 to which air is pumped by fluid pump means to maintain air under pressure above the oil, and to the body of said air under pressure, and oil is supplied to the reservoir by means comprising an injector 110 energized by air pumped by said fluid pump means e.g. an air pump 16. Air is fed to the conduit 20 by a fan 14 driven by an electric motor 12 which also drives the rotary sliding vane type air pump 16 which discharges air through the venturi of an injector 108 into the reservoir 10 above the oil level therein. The air under pressure is conducted through a duct 62 to the pipe 60 leading to the air passages 30 in the burner nozzle. The maximum pressure in the reservoir 10 may be controlled by a weight relief valve 112 or by a bleed passage provided with a regulating screw. Oil is supplied through conduits 126, 132 to a vessel 130 within the reservoir 10, and to which the throat of the air injector 108 is connected by a passage 134 so that when the injector is operating the pressure within the vessel 130 is reduced to allow oil to enter therein. When the oil in the vessel 130 reaches a predetermined level a valve 144 is opened by a float operated snap-acting mechanism comprising levers 156, 152, a tension spring 158, and a float 166. The pressures in the vessels 10, 130 are then equalized to permit oil to flow from the vessel 130 past a check valve 142 into the reservoir 10. The fuel supply line 126 contains a control valve 136 actuated by a diaphragm 190 exposed at the lower side to the atmosphere, the upper side communicating through a passage 194 with the line 126 so that when the chamber 130 is at reduced pressure the diaphragm 190 moves upwardly to lift the valve member 180, allowing fuel to flow into the vessel 130 until the reduced pressure therein is eliminated by the opening of the valve 144, whereupon the valve member 180 is seated by a spring 184. The fuel is fed from the reservoir 10 to the burner pipe 46 through a passage 54 and a metering orifice 58.

Patent GB-237610-A (GB)
Abstract: 237,610. National Cash Register Co., (Assignees of Robertson, W. H.). July 26, 1924, [Convention date]. Cash registers; keyboards.-A cash register, for example of the type described in Specifications 8119/15, 191,350 and 191,351, is provided with means for facilitating subtraction by the complementary method. For this purpose the keys are affected by a single setting movement so as to display the complements of their normal digits and by the same setting action a " transfer-mechanism " applied to the units differential mechanism is rendered active in order to add the " fugitive one." Each amount bank contains ten keys (0-9) and each key consists of the usual stem 30, Fig. 7, provided with a cap 35 apertured to expose the digit, marked on a rotatable flanged sleeve 37. Each sleeve has two digits, mutually complementary, disposed at 90‹ apart, and by rotating the sleeve either figure can be brought into view. This rotation is effected by moving a finger lever 44 counterclockwise so as to displace endwise a series of curved racks 42 engaging teeth on the sleeves. This displacement of the racks also effects, by means of hooks 85, rock-arms 87, Fig. 2, pins 90 and arms 91, the withdrawal of the zero trip pawls 73. For adding 1 to the units the known form of transfer-device employed in these machines is applied in the units denomination and is rendered active by means of a three-armed lever 127 adapted to trip the arms 131 to free the transfer levers 100 of the units bank. The lever 127 is rocked for this purpose by an arm 126 connected to a lever 123 adapted to be rocked by a pin 122 on a lever 79 having a pin 80 embraced by the hook 85 of the units bank. The zero trip pawl of this band is withdrawn by a second lever 82 one arm of which rests upon the extension of pin 80. The disablement of the zero trip pawls in total-taking operations is effected by the setting of the total lever through the medium of the usual shaft 89 pins on which co-operate with slots in the hubs of the pawl-withdrawing levers 87, 82.

Title: Improvements in or relating to flat knitting machines
IPC: D04B7/04
Filed: 1964-06-09
Abstract: 1,002,549. Knitting- machines. H. STOLL, G. STOLL, E. STOLL, E. STOLL Jnr, J. STOLL, A. STOLL,R.E.STOLL, and M.STOLL. June 9,1964 [June 10,1963], No. 23793/64. Heading D1C. A flat bed machine having means enabling a fully fashioned patterned fabric to be produced is provided with needle controlling mechanism which ensures that the marginal portion of the fashioned fabric is of an unpatterned nature. Selectors 12 are arranged in slots in a selector bed 11 and correspond to the number of needles 2 in the needle bed. The selectors are pivoted at 12<SP>1</SP> and each has an upstanding projection 14 such that when the selector is pivoted the projection 14 projects through a slot 15 in the needle bed and engages and raises a corresponding needle jack 3 thereby bringing the jack butt 3<SP>11</SP> into the path of a cam 10 on the cam carriage. A further butt 3<SP>1</SP> on the jack 3 is then caused to engage the cams 8, 9 whereby the jack causes the needle 2 to be projected to engage the knitting cams 4... 7 and thereby take and knit yarn. The pivoting of the selectors and thereby the selection of the needles to take and knit yarn is normally determined by a bank of selector cams 17 which are movable into and out of an operative position to engage butts 16 on member 13 engaged over the upper end of the selector 12. When in a lowered position with a rear projection engaging a lower recess 23 in the selector 12 the butts 16 are in alignment with the cams 17 so that patterning can be achieved on the corresponding needles by selection of the cams 17. At the marginal portions of the fabric where unpattern effect is desired the member 13 is raised on a number of selectors so that its rear projection engages an upper recess 23<SP>1</SP> and in which position the butts 16 no longer remain aligned with the cams 17 and are thereby uninfluenced by the cams. Simultaneously, however, an upper butt 13<SP>1</SP> on each of the elevated members 13 is aligned with a cam 24 which actuates all of the elevated members 13 and a corresponding selectors and ensures that the associated needles are operated and knit. The members 13 which correspond to the needles which as fashioning progresses become the marginal needles at each end of the needle bed, are raised to their elevated position by a lifting lever 18 one at each end of the bed and each having a width which extends beneath the butt 13<SP>11</SP> of several members 13. The levers 18 are mounted on a rod 19 and are movable therealong according to the dictates of the fashioning mechanism so that in turn they are positioned beneath the butts 13<SP>11</SP> of the operative end members. As the cam carriage is traversed a presser bar 20 thereon engages an arm 18<SP>1</SP> of the lever 18 pivoting the lever and thereby raising the end members 13 to their elevated position to be engaged by the cam 24.

Abstract: 187,791. Loss, 0., and Grove Akt.-Ges., D. Sept. 8, 1921. Separators. - An apparatus for separating solid and liquid impurities such as water, mud, granular dust &c. from steam, compressed air, or gases, is characterised by the feature that one or more sharp edged separating members c, e project into the fluid jet which is spread out in the form of a domeshaped mantle. The fluid to be separated flows into the separator in a circular or rectangular jet of full bore and is spread out between a bodv b and the flared end of the inlet pipe g. The sharp edged separating member c separates the sedatively heavy impurities which escape through the approximately horizontal nozzle between the body b and member c and which is designed so that the pressure there is greater than the pressure in the space d below, to prevent suction on the separated impurities. The member e projecting from the side of the casing effects further separation and the separated fluid finally escapes at the outlet m. Separated liquid is drawn off at h and mud &c. is blown off at p.
