Filed: 1927-03-31
Abstract: 268,795. British Thomson-Houston Co., Ltd., (Assignees of Norris, M. L.). April 5, 1926, [Convention date]. Alternating - current commutator machines; brush holders.-A motor starting as a repulsion machine and running as an induction machine is provided with rotatory speed-responsive means for short-circuiting the commutator and with separately-actuated non- rotary means controlled by the speed-responsive means for pressing the brushes away from the commutator after the commutator has been short-circuited. The commutator 5 is shortcircuited by a disc 20 mounted on a sleeve 18 slidable on the shaft and maintained in the open circuit position by a spring 23. The speedresponsive device consists of spaced plates 12, 13 between which are located weights 14 carrying inclined members 15. At a predetermined speed the weights fly outwards and the members 15 assume positions more nearly parallel with the shaft, with the result that the plate 13 moves to the right and this movement is transmitted to the sleeve 18 through rods 19. The brush-holder 30 is carried oy a bracket 27 and is pivoted on a stud 31. The necessary pressure on the brush 28 is given by a spring 32 coiled on the stud 31. Movement of the holder towards the commutator is limited by a stop 39. The brush-holder as a whole is rotatable about its pivot and is kept in its operative position by a light spring 41 connected to the stop 39 and to a lug 40 on the holder. Lifting of the brushes is effected by a spring-urged plate 48 which follows the movement of the sleeve 18. This plate in its travel engages a nose 44 on a member 42 pivoted on the stud 31 and the action is such that a cam face 45 on the member 42 first clamps the brush and then the brush-holder is rotated bodily away from the commutator. To eliminate unnecessary friction the parts are so arranged that the plate 48 reaches its limiting position before the sleeve 18 completes its travel whereby a small space is left between the plate and the end of the sleeve. To prevent derangement of the speed-responsive device due to accidental movement of the plate 18 to the right, a weak coil spring may be provided around the sleeve 11 so that the plate 12 will follow the plate 13 if such movement occurs.

Abstract: 1,071,984. Purifying exhaust gases. BENTELER-WERKE A. G. March 3, 1965 [March 4, 1964], No. 9110/65. Heading F1B. Exhaust gases from an I. C. engine, mixed with air, flow inwardly through a spiral conduit 1 to a catalyst-filled combustion chamber 3, purified gases passing to atmosphere via a spiral conduit 2, in heat exchange relationship with conduit 1. The catalyst is mounted in a housing 11, at least wall 13 of which is sieve-like to permit the exhaust gases and air to enter the combustion chamber. A baffle plate 16, which may be apertured, surrounds an incandescent plug 14 so that a conical region of the catalyst surrounding the plug is substantially shielded from the exhaust gas flow and thus not cooled thereby. When the temperature of the purified gases becomes excessive, a bi-metallic strip (not shown) in conduit 2 is operative to open a passage between conduits 1 and 2, the exhaust gases then by-passing the combustion chamber. Alternatively, this passage may be opened by an electromagnet (27), Fig. 4 (not shown) controlled by a temperature responsive element (26) embedded in the catalyst. The element 26 may also control a further electromagnet operative to obstruct air supply ports, Figs. 6 and 7 (not shown), in the engine exhaust pipe, or may alternatively control a blower supplying the air.
