Title: Improvements in electric motor starters
IPC: H01H25/06
Filed: 1930-10-18
Abstract: 363,046. Actuating drum controllers. BROOKHIRST SWITCHGEAR, Ltd., Northgate Works, and LANCELEY, C., 12, Lime Grove, Hoole, both in Chester. Oct. 18, 1930, No. 31250. [Class 38 (iii).] With auxiliary switches.-A starter is provided with an auxiliary switch, the moving contact of which partakes of the rotary movement of the starter, and is also moved axially by a secondary movement of the starter handle, so that in the various angular positions into which it is moved, it may connect its fixed contacts together in appropriate combinations and sequence. A drum A is rotated by a handle C which, in the position shown dotted, acts by means of a cam to move a switch member E axially into engagement with fixed contacts P, Q, R, S. When the handle C is released, a spring returns it to the lower position and a second spring moves the switch E into its open position. In angular positions corresponding to the " full on " and " full off " positions of the starter, a cam maintains the switch E closed when the handle C is released. With the gear in its first or " off " position shown the switch E connects contacts Q, S, so that by closing an " inching " button J coils f1 are energized to close contactors F and to start a motor M with resistance G in series. If then the handle C be raised and the starter moved to its second position contacts Q and R are connected so that the motor may be " inched " by movements of the handle C. With the handle C raised, and the gear moved to any of its further positions, contacts P, Q are connected so that the contactors F are energized over a switch mechanically connected with one of the contactors F. Thus resistance may be removed from the motor circuit under conditions such that the release of the operating handle C will open the circuit, and require the movement of the gear to a full resistance position before the motor can be again started. A switch W which may be interlocked with the motor field regulator is provided for preventing " inching " under certain conditions. In Fig. 9 (not shown) the starter is adapted to control the rotor resistance of an alternating current motor. Specification 166,084, [Class 38 (iii). Electric motor control systems &c.], is referred to.

As shown the lower coils are seriesconnected into three groups associated with respective thyristors Q1-Q3 and the upper coils form three further groups 21, 27, 33 &c. associated with thyristors Q4-Q6. The TV subscriber presses a reset button (48, Fig. 2, not shown) in his equipment to temporarily remove supply potential to all thyristors Q1-Q6 by breaking a phantom return circuit formed by the programme conductors 40, 41 in his distribution cable 10. He dials a first digit over control line 38, the corresponding charge being transferred from C2 through CY1 and CY2 depending on magnitude and thereby fires a corresponding thyristor Q1-Q3 to enable a corresponding coil group. A second dialled digit is received over line 39 to fire a second thyristor Q4-Q3 and energize a second coil group. The electromagnet whose coils are thus energized connects the selected programme over conductors 40, 41. The programme is HF video and AF and/or HF modulated sound.

Title: Improvements in or relating to gear wheels
IPC: F16D3/76

Abstract: 153,878. Akt.-Ges. der Maschinenfabriken Escher, Wyss, et Cie, (Assignees of Kcller, H.). Nov. 14, 1919, [Convention date]. Toothed wheels; racks.-Toothed, spur, helical and worm wheels are rendered resilient by inserting a solid or inflated ring or rings of soft and elastic material such as rubber, leather &c. between the rim and the centre or hub portion, the drive being transmitted by the frictional grip between the parts. In one form, the rim and teeth are so proportioned as to be flexible in themselves. In the form shown in Fig. 1, the toothed rim 1 is connected to the centre 2 by means of two inflated tubes 3, 4 enclosed in covers 5, 6, each formed in two parts, the joints being disposed in planes parallel to the plane of the wheel. The gaps between the rim 1 and centre 2 are closed by rings 7 and 8, fixed to the centre 2. In the form shown in Fig. 2, solid conical rings 24, 25 of rubber are gripped between the inner conical surfaces on the rim and fixed and movable surfaces 27, 28 drawn together by bolts 31 on the centre 26. In a modification of this form, a single centre carries two toothed rims similar to that shown in Fig. 2, the intermediate seating being provided by a double conical ring inserted between the fixed and movable rings 27, 28. In the form shown in Fig. 4, a cylindrical rubber ring 53 is pressed outwardly against the toothed rim 52 by a pair of tapered tightening rings 55, 56 bearing against conical surfaces on the centre disk 54 and drawn together by bolts 57, metallic plates 58 of the form shown in Fig. 5 being interposed between the ring 58 and the sliding rings 55, 56. The parts may be of cylindrical formation only, the rubber ring being cast round a base ring and the toothed rim shrunk on to the rubber ring, the composite rim thus formed being hydraulically pressed on the wheel centre. In this form the rim and teeth may be proportioned as shown in Fig. 7 so as to be flexible under the torque of the driving gear 66. The Specification as open to inspection under Sect. 91 (3) (a) states also that the invention is applicable also to toothed racks. This subjectmatter does not appear in the Specification as accepted.
