Abstract: 765,988. Tying packages. BUNN CO., B. H. March 15, 1955 [March 25, 1954], No. 7508/55. Class 94(1). A machine for tying twine round bundles of envelopes, or like bundles compressible adjacent their edges comprises a platform to shape the end of the bundle in the vicinity of the knot, the knot being inwards of the shaped end and the platform having a curved contour adjacent the knot and terminating in a tab at right angles to its supporting. surface. The machine comprises a rotating twine arm 40 receiving twine from a spool 51 and leading it to a holding device 52 adjacent the knotter 50a of known form. The bundle supporting platform comprises two parts, one of which 89, has an upcurved portion 95 for shaping the bundle end terminating in a resilient tab 94 against which the end of a bundle is placed as it is laid on the platform. The tab 94 is supported by a rigid bracket 96. When a bundle 91 is placed manually on the platform it must be pressed down against a rod 90 passing through the tying gap in the platform. The bundle is somewhat compressed and the rod 90 pivots at 87 to operate a clutch 28, Fig. 2, through linkage 72, 74, 76, 80, Fig. 3, and cause rotation of a camshaft 65 to commence the tying operation. The arm 40 rotates to place one or more turns of twine round the bundle and then a cam disc 64 raises a lever 106 causing part of the platform adjacent the tab 94 to be raised by a push rod 104 acting on a pivoted element 97, Fig. 6. The knotter 50a is carried on a swinging frame 57 pivoted at 62 and is driven by an intermittent gear 68, Fig. 3, engaging a gear 67 on a driving shaft journalled in the frame, Fig. 6. The frame has a roller 63 in the path of the cam disc 64, and as the platform portion is raised, the frame swings the knotter beneath the raised portion into the operative position for tying a knot in known manner. The bundle may then be turned through 90 degrees and tied again.

Abstract: 396,326. Windings for dynamo-electric machines. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, and WILSON, J. C., The Abbey, Great Haywood, Stafford. March 13, 1933, No. 7572. '[Class 35.] In a continuous-current dynamo-electric machine having two series connected armature windings with the commutators at opposite ends of the armature, a side of each coil shortcircuited by a positive brush on one commutator is adjacent to a side of a coil shortcircuited by a positive brush on the other commutator. The object of the invention is to ensure that the maximum voltage between the upper coil side of one winding and the lower coil side of the other winding never exceeds half the total voltage of the machine. In Figs. 3 and 4, two double layer windings are shown displaced longitudinally but in practice they would be superposed so that each slot contains four conductors, the top coil sides of each layer being shown in full lines and the bottom coil sides in dotted lines. According to the form shown in Fig. 3, the coils of the two windings progress in the same direction round the armature but they are of opposite hand, that is if the left-hand side of a coil of one winding is at a higher level than the right-hand side, reverse conditions obtain for the other winding. In the second form, Fig. 4, the windings are both of the same hand but progress in opposite directions round the armature. Fig. 2 shows a section through a slot containing the conductors O, N, B, C for the connection shown in Fig. 4. With the connection according to Fig. 3, coil sides O, N are interchanged.

Abstract: 513,586. High-vacuum apparatus. EASTMAN KODAK CO. March 11, 1938, No. 7582. Convention date, March 11, 1937. [Class 71] The booster condensation pump of the apparatus is operated by a fluid of a vapour pressure between .05 and 2 X 10<-6> mm. Hg. which is used at a relatively high boiler pressure, above 2.5 mm., and operated against a high back pressure of .3 to 10 mm. The pump is interposed between a fine pump and a backing- pump to produce a vapour pressure less than 2 x 10<-6> mm. The fluid used in the booster or intermediate pump is purified by a fractionating device. A steam ejector may be used as a backing pump. Evacuation to 10<-7> may be obtained with octyl phthalate in the fine pump. In the apparatus shown in the Figure, the part 1 is connected to the chamber to be evacuated and carries a chamber 3 with a flared jet 4 with an electrically-heated boiler 16. The booster pump B has a boiler 5 and a conduit 6 leading to a nozzle 7. The surrounding chamber 9 communicates with the part 1 and with a fluid-cooled condenser 10. A pump 14 returns condensate to the boiler 5. An arrangement of steam ejectors C, D, E is used as a backing-pump. Superheated steam at about 170‹C. is supplied through pipes and valves to the boiler B and ejectors. The pump fluid in B is heated to vaporizing temperature under a boiler pressure considerably in excess of .3 mm. Hg. The gases from conduit 2 are entrained in the jet from nozzle 7 and forced into conduit 15. Dimethyl-phthalate in pump B is heated to give a boiler pressure of between .5 and 10 mm. When the system pressure is below .1 mm., pump A is started. Di-octyl phthalate (apilson oil) is here used. The condensed vapour from jet 4 re-enters the boiler through opening 3. Valve 30 controls the rate of vaporization and temperature in boiler 5. Suitable pump liquids are petroleum distillates having a vapour pressure not greater than .1 mm. at 20‹C. or less than .1 mm. at 160‹C.-dimethyl, ethyl, propyl and butyl phthalates, diglycerol tetrapropionate, tripropionin, tributyrin, triamylin, amyl naphthalene, squalene and the hydrocarbon obtained by the molecular distillation of a fish oil, as described in Specification 501,841, [Group III].
