Title: Improvements in or relating to magnetic coupling arrangements
IPC: F16J15/50
Filed: 1958-12-09
Abstract: 854,896. Magnetic couplings. WESTINGHOUSE ELECTRIC CORPORATION. Dec. 9, 1958 [Dec. 17, 1957], No. 39631/58. Class 35. A magnetic coupling has a rotor 72 bearing salient poles which is sealed within a closed system and is driven by a rotating field provided by magnets on rotor 22 which is turned relatively slowly by motor via reduction gearing (Fig. 1B, not shown). Rotor 22 comprises a non- magnetic stainless-steel supporting sleeve 66 to whose inner surface are secured four equally spaced clamping members 76 each extending along most of the length of the sleeve, which clamping members secure four magnets 88 inside the sleeve. The magnets equal in length to the clamping members, are curved (Fig. 2) and are laterally magnetized, being arranged so that similar poles of two magnets are in contact with each clamping member 76, the clamping members thus forming extensions of the magnets towards rotor housing 48 and driven rotor 72. If rotor 72 is used within a highly pressurized sealed system rotor housing 48 is formed of material having low or intermediate permeability and is sufficiently thick to withstand the pressure. Inside housing 48 is driven rotor 72 which has four salient poles 104 and is of non- magnetized magnetic material. Rotor 72 rotates on ball-bearings 120, 122 which are so mounted that removal of housing extension 140 by removal of bolts 150 allows the driven rotor assembly to be withdrawn from the housing in one piece since outer race 124 of bearing 120 slides freely in housing 48. Similarly field rotor 22 is mounted on ball-bearings 50, 70 and can be withdrawn by removing annular lock-nut 62 and lock-washer 64, inner race 84 of bearing 70 sliding freely on housing 48. Specification 765,040 is referred to.

Title: Improvements in or relating to hydro-pneumatic suspension systems
Inventor: WORDSWORTH JACK
IPC: B60G17/044
Filed: 1958-12-11
Abstract: 870,826. Hydropneumatic vehicle suspensions. ARMSTRONG PATENTS CO. Ltd. Dec. 4; 1959 [Dec. 11, 1958], No. 39935/58. Classes 108(2) and 108(3). A hydropneuinatic vehicle suspension has piston and cylinder means 22, 24, Fig. 1, connected between the sprung and unsprung masses, an elastic diaphragm 28 forming spaces 34, 38 containing hydraulic and gaseous media, a relief valve 94, Fig. 6, to exhaust liquid from the space 34 into a reservoir 12, a pump 46, Fig. 2, to transfer liquid from the reservoir 12 into a pressure accumulator 68 and a valve 82 operated by contraction of the piston and cylinder means to admit liquid from the accumulator to the space 34 to restore the piston and cylinder means to their original relative position. The piston is connected by a rod 20 to a crank-shaft 16 having an eccentric spigot 50 for operating the pump, and cams 88 and 100 for operating the valves 82 and 94. As long as the piston 24 is at a desired mean position within the cylinder 22 oscillatory movements of the spindle 16 cause the pump to transfer liquid from the reservoir 12 to the accumulator 68 until a predetermined pressure is reached when a blowoff valve opens to return surplus liquid to the reservoir: If the loading on the vehicle increases the piston enters further into the cylinder. Simultaneous opening of the valve 82, however, enables liquid from the accuniulator to push the piston back to the desired position. A decrease in vehicle load causes withdrawal of the piston until the valve 94 opens to allow liquid from the space 34 to flow into the reservoir 12. Flexible diaphragms 44 and 74 form pneumatic springs in the reservoir 12 and accumulator 68. The crankshaft 16 may be operated by the upper link of an independent wheel suspension and one hydraulic accumulator may be connected by conduits to two or more wheel cylinders.
