Title: A method of expanding tubes
IPC: B21D39/06
Filed: 1967-01-19
Abstract: 1,126,142. Jointing by tube expanding. W. BUSCH. 19 Jan., 1967 [24 Jan., 1966], No. 2916/67. Heading B3J. In expanding a tube into an orifice by a tubeexpander with skewed rollers and a mandrel driven by a prime mover, the direction of rotation of the prime mover is reversed automatically for a selectable period upon the prime mover reaching a torque appropriate to the desired engagement between the tube and orifice, after which period the prime mover is again switched automatically to its original direction of rotation and the expander moved along the tube to expand a different section. The period of reverse running may vary between 0-1 and 10 seconds, and due to the skewed rollers the mandrel withdraws slightly. A stop may limit penetration of the expander into the tube.

[Also in Group XVII] Pile tablets; sheet-separators.-In a machine for packeting measured quantities of seeds or powdered materials in envelopes or bags, the envelopes are stacked in a receptacle which is moved intermittently towards and away from a rotary work table and envelope - separator, whereby clips on the table can engage an envelope and detach it from the stack. As shown, a rotary table a is adapted to be rotated in steps to. six positions at which an.envelope, is attached to the table, is fully opened, is charged with seeds &c., is subjected to tamping, the flap is gummed, and a final position at which the envelope is released. Unidirectional angular movements are imparted to the table a by an oscillatory cam c arranged in a central recess d in the table, and six equi-spaced pawls e, slidably mounted in radial recesses in the table, which are alternately engaged by a shoulder h on the cam c during successive movements of the cam in one direction. The pawls are urged inwardly by springs g towards the cam which is secured to a vertical driving shaft j. The outer end of each pawl e has a clip m in the form of a downwardly-projecting plate adapted to enter the open mouth of an envelope, when the pawl is projected outwardly by the cam c, and to be moved inwardly by the springs g to attach the envelope to the face of the table a. The clip m moves between two abutments 4 on the table which deflect the outer side of the envelope to open the latter. The envelopes b are stacked vertically, with mouths uppermost, flaps extended, and rear faces presented towards the table a, in a troughshaped receptacle n having adjustable sides s, the stack being urged forwardly against small projections p by a weighted or spring-pressed lever q (not shown). The receptacle n is secured to an arm t on the upper end of a vertical shaft u which is adapted to be rotated and reciprocated axially by cam and lever mechanism, whereby the receptacle can be swung from the dotted to the full line position adjacent the table a, and then raised so that the open mouth of a clip m engages within the front envelope; return movement of the receptacle causes the front envelope to be detached from the stack, this being synchronized by the inward movement of the corresponding pawl e. The charged envelopes may be transferred to another rotary work table described in Specification 686,552, [Group XVII].

Title: Improvements in and relating to time element electromagnetic devices
IPC: H01H43/30
Filed: 1948-02-02
Abstract: 645,209. Electromagnets. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 2, 1948, No. 3021. Convention date, Feb. 4, 1947. [Class 35] [Also in Group XXXVII] An A.C. electromagnetic device is given a delayed action by subjecting the armature 2 not only to the attraction of the core 1 when the winding 13 is energized but also to an opposite effect due to the repulsion of a short-circuited winding 22 by the winding 13. The winding 22 is heated by the current induced in it and its resistance increases till the effect of the winding 13 overcomes its effect and the armature is attracted. In the form shown in Fig. 1 the armature 2 is pivoted at 5 and has three arms at its upper end, the centre arm being adapted to enter a notch 12 in the core 1 and the two outer arms resting on the copper ring 22 which is pressed outwards by a spring 25. In the modification shown in Fig. 3 the short-circuited winding 22<SP>1</SP> is mounted on a lever 29 pivoted at 51 and pressed by a spring 35 against a rotatable cam 32 on the armature 2<SP>1</SP> that is also pivoted at 5<SP>1</SP>. Thus adjustment of the cam 32 will move the winding 221 relatively to the armature, thus varying the repulsion effect on the winding 22<SP>1</SP> and with it the time lag. In action, the armature and winding 22<SP>1</SP> normally move together about the axis 5<SP>1</SP> at the end of the time period. against the action of a weight 38, adjustment of which varies the " pick-up " value of current. A heavy short-circuit current, however, operates the armature 2<SP>1</SP> instantaneously, the armature 2<SP>1</SP> moving relatively to the coil 22<SP>1</SP> while the spring 35 is further strained. In a further modification, Figs. 5, 6 (not shown), the armature and short-circuited winding are both adjustably mounted on a screwed spindle that passes through the operating coil and moves rectilinearly.
