Abstract: 481,751. Control of D.C. motors. GENERAL ELECTRIC CO., Ltd., and CROFT, E. H. Sept. 23, 1936, No. 25848. [Class 38 (iii)] i i Varying E.M.F.-A range of speed control for a group of motors is obtained by connecting two similar sources in series or in parallel, and in order to provide a continuous tractive effort during the transition from parallel to series connection of the sources, the motors are first connected in series across one of the sources with the other source disconnected, then some of the motors are short-circuited through a resistance and the remaining motors supplied from the first source, then the disconnected motors are reconnected to the other source with a connection common to the sources and the two groups of motors, and finally the common connection is broken. In the first step of a controller contactors BP1, BP2, LS1, S1, S2, S3, and G4 close to connect motors A1-A4 in in series across battery sections B1. B2, connected in parallel, and on the second and third steps contactors 1-4 and 5-8 are closed to short-circuit resistances R1, R2, in two steps. The battery connections are then charged from parallel to series in a series of transition steps. The contactor BP2 is first opened, contactors 1-8 are then opened and a contactor B closed, followed by the opening of the contactor BP1, and finally the closure of the contactor BS. Further speed control is effected bv the resistances R1, R2, and the change from series to series-parallel and from series-parallel to parallel connection of the motors. Stages of field weakening may also be employed. Means may be provided so that alternative sections of the battery take the load during transition from parallel to series connection of the battery sections, and resistances may be connected in the battery circuits during the parallel connection thereof.

Letters and envelopes are fed from separate magazines to a common plane in which the envelopes move in a particular direction and the letters are fed into them at right angles to that direction. As shown, the envelopes 6 are removed from a magazine 1 by means (9-20), Fig. 1 (not shown), as described in Specification 1,084,262, and deposited on a table 22 which is provided with slots 23. The envelope is impelled by transfer levers 25 past flap opening means comprising an air blast from a nozzle 36, and a plough member 37. Conveying rollers 38 move the envelope beneath a roller 39 which moistens the adhesive on the flap 7.

The enclosures 53 are removed from magazine 52 by a suction device (not shown) and rollers 16<SP>1</SP>, analogous to the device for magazine 1. The enclosure is then inserted in the envelope by transfer levers 54 operating similarly to transfer levers 25, and by pawls 55 similar to pawls 44. To facilitate insertion, a blast nozzle 56 and openers 57 moved in the transverse direction are provided. The filled envelope is moved by levers 58 to pass between rollers 61, arriving at a delivery table 62 provided with slots 63 through which pass transfer levers 64.

Abstract: 364,620. Automatic circuit-breakers. ALLGEMEINE ELEKTRICIT€TS - GES., 2, Friedrich Karl-Ufer, Berlin. Sept. 1, 1930, No. 26108. Convention date, Feb. 8. [Class 38 (v).] An automatic circuit - breaker of the screw plug type is operated by a guided press-button a, Fig. 1, carrying pivotally a lever b the free end of which bears a roller k engaging between projections w<1>, w<2>, Fig. 3, of a pivoted tumbler member d. The rotation of this member strains a coiled spring t surrounding the pivot on which the contactcarrying lever g is mounted so that towards the end of the closing operation the lever g slips past the bent-over projections r of the lever b and is moved rapidly by the strained spring t to cause the rectilinearly guided contact bridge h to engage fixed contacts q. The switch may be tripped on overload either by an electromagnet plunger m or by a bimetallic strip z<1>, the former operating the release lever o directly through a push rod n and the latter when heated moving to the right followed by a blade spring z<2> which releases an intermediate lever i acting on the release member o. The release member o on rotation engages by a projection o<1> the roller k and lifts it out of the recess in the tumbler member which, under the action of a throw-off spring f engages the contact carrying lever g to open the circuit-breaker. This action is independent of the return of the pushbutton a and operating member b which are returned separately by relatively light springs z surrounding the guides for the pushbutton. A releasing pushbutton a<1> is arranged to act as the releasing lever o for providing manuallyoperated tripping action.
