Filed: 1916-04-01
Abstract: 100,307. Farge, F. C. April 16, 1915, [Convention date]. Addition to 24223/12. Clockwork - actuated valves. - A clock-work apparatus for lighting and extinguishing gasburner jets, as described in the parent Specification, is provided with additional mechanism for extinguishing a certain number of the jets at an intermediate time. This mechanism comprises a two-armed lever g, d<11>, d<111> operating in conjunction with a face-cam f having a gradual rise 44 and a drop 45. An additional valve 51 controlling the pilot-light supply is also mounted on the valve spindle. In lighting up, after the stoppin 38 on the eccentric has been released by the lighting-lever d, it is arrested by the arm d<11> of the special lever g, as shown, the valve 7, 8 being central and supplying gas through passages 49, 50 to all the jets; the pilot valve 51 is closed. At the intermediate extinction time. the drop 45 in the face-cam allows the lever g to be pushed back by the spring 40 to release the pin 38, which then moves over to the extinguishing-lever d<1>. The valve face 8 then cuts off gas from the jets supplied by the passage 49. For the complete extinction when the lever d' releases the pin 38, the valve 7, 8 is moved over to the extreme left hand, thereby completely cutting off the gas supply, and opening the pilot valve 51. The face-cam is adjustably mounted on its shaft by means of internal teeth.

Abstract: 606,707. Resistance measurements; electric tests. WILKINS, S. R., and AUTOMATIC COIL WINDER & ELECTRICAL EQUIPMENT CO., Ltd. Feb. 18, 1946, No. 5006. [Class 37] The mutual conductance of a thermionic valve is measured by applying to its anode an alternating voltage of r.m.s. 1.1 the direct voltage normally applied for the measurement, while the grid is supplied with alternating voltage of opposite phase having the positive peaks suppressed and of mean value 0.5 the direct voltage normally applied for the measurement. The resulting anode current is proportional to the mutual conductance. Preferably the ammeter is calibrated to read double the actual current, and the value of the voltage applied to the grid can be changed by a switch. For a screen grid valve, the screen grid is supplied with alternating voltage of r.m.s. 1.1 the direct voltage normally applied for the measurement. Suppressor grids would be supplied as control grids. To test the efficiency of rectifiers, the circuit is modified by connecting a condenser C Fig. 5, in shunt with a resistance L and meter M in the anode lead of the rectifier. Specification 480,752 is referred to.

Abstract: 1,058,884. Feeding webs. DENNISON MANUFACTURING CO. Ltd. Feb. G, 1964, No. 5128/64. Heading B6B. [Also in Division B8] In a labelling machine, a web feeding arrangement from a feed roll to a take up roll via an intermediate web driver has tension sensing detectors either side of the intermediate driver, acting respectively on the feed roll and the takeup roll to control the tension of the web. A yielding interconnection is provided between the two detectors so that the tension of the web either side of the intermediate web driver is maintained equal. Feeding webs.-The web is fed from a web roll 1, Fig. 4, by a continuously rotating pinwheel feed 3 via a dancing roller 5, which controls via linkages and levers 72, 68 and 64 a brake 61 acting on the web roll spindle. The chalk applied to the take-up roll 2 is controlled by a dancing roller 12, Figs. 3 and 4, acting through linkages and levers 99, 94, 91 and 89 on a clutch arrangement 83 and 84 driven by a continuously rotating sprocket 82. A yielding interconnection between the two levers 99 and 72 supporting the dancer rollers 12 and 5, respectively, comprises a fluid pressure piston and cylinder arrangement 78, 79. The pressure of the fluid entering through the conduit 81 is controlled manually to preset the tension in the web. The yielding interconnection between the detectors may be a spring. Means are provided for adjusting the distances x and y, Fig. 4, and by adjusting these distances relatively to each other an initial balance of tension on opposite sides of the pin-wheel 3 can be obtained. Labelling.-The web carries labels which are to be applied to glass phials mounted on a turret 26, Fig. 1 (not shown). The web passes from the pin roller 3, over rollers 7 and 8, heated platens 58 and 59 and over a cam operated reciprocating transferring roller 16. heated by a member 24, before passing to the dancer roller 12 of the take-up mechanism. An intermittent controlled registering feed is achieved with looping rollers 13 and 7 attached to a member 51, Fig. 4, reciprocated by arm 52. The turret at 26 is intermittently stepped around in the direction of the arrow, Fig. 1 (not shown), by a reciprocating rack 28. Burners 44, situated around the turret are used to heat the phials before transfer of the labels thereto by the roller 16.

Filed: 1964-02-06
Abstract: 1,020,173. Overload slip couplings. BORGWARNER CORPORATION. Feb. 6, 1964, No. 5167/64. Heading F2C. An overload slip clutch has means responsive to the torque transmitted providing a force in opposition to the engaging force to determine the maximum torque transmittable, the means being adjustable to vary the maximum permissible torque. A driving, or driven, plate 20 is clamped between driven, or driving, plates 26, 28 by springs 34, the plate 28 having threearmed levers 44 pivotally mounted thereon at 46, each lever having arms 48, 50 engageable with the ends of bolts 38 which are adjustably fixed in the plate 26 and pass through clearance holes in the plate 28, each lever 44 having a third arm 52 passing through an aperture in a flange 58 of a sleeve 56 which carries fittings 64 by which the sleeve is connected to a driven, or driving, shaft. The sleeve 56 can be adjusted axially of a driving, or driven, shaft 10 by changing the size of a spacer 62 between which and a collar 60 and lock nut 63 the sleeve is fixed axially to the shaft. Axial adjustment of the sleeve 56 varies the effective length of the arm 52 to vary the maximum torque transmittable by the clutch. In operation, assuming shaft 10 to be the input shaft, rotation of the driven plates 26, 28 rotates the levers 44 the arms 52 of which rotate the output sleeve 56, and the transmitted torque causes the levers 44 to pivot so that the arms 48 or 50 engage the corresponding bolts 38 to produce a bias in opposition to the engaging springs 34. Upon, overload the bolts 38 are shifted axially to disengage the clutch. If the clutch is to transmit different torques for different directions of rotation the arms 48, 50 are of different lengths. The bolts 38 may be adjusted in the plate 26 to minimise backlash and compensate for wear.
