Title: Improvements relating to electromagnetic relays
IPC: H01H51/20
Filed: 1944-08-28
Abstract: 582,960. Electomagnetic relays. SIEMENS BROS. & CO., Ltd., and CHRISTIAN, D. A. Aug. 28, 1944, No. 16315. [Class 38 (v)] An electromagnetic relay has two or more armatures 4, 5 which rest against one limb 2 of a single core structure 1 and are carried by springs 6, 7 which are pressed by springs 8, 9. The core carries energizing windings, and the free ends of the armatures are normally spaced from the limb 3 of the core. When the core is energized the armatures are attracted to the limb 3. In order to prevent transfer of flux from the core limb to a non-adjacent armature due to one armature moving more quickly than another, one or both of the limbs are slotted as shown at 10, 11 in order to segregate the flux paths from the core to the several armatures. The slits 10, 11 may be filled with non-magnetic material. Specification 536,151 is referred to.

Title: Watertight motor with short-circuit rotor
IPC: H02K5/128
Filed: 1928-06-07
Abstract: 308,244. Surjaninoff, M. March 20, 1928, [Convention date]. Casings.-In a watertight motor having a protective envelope in the air gap forming an enclosure for the oil - immersed stator and having ends in the form of yielding undulated metal members, the envelope rests at its ends on supporting devices, such as cross-armed supports, which allow it to expand axially but prevent radial movements. In the form shown, the enclosing tube 2 in the bore is preferably magnetic and of the same thermally expansive character as the stator structure and is rigidly secured to the casing at one end by a ring 6. The other end is elastically connected to the casing either by means of a rubber diaphragm, as shown at 4, or an undulated metal diaphragm 9. A ring 7 having radial arms allows axial expansion of the tube 2 but prevents it from moving laterally. The lower bearing is not packed, with the result that the outer liquid can enter the air gap and pass therefrom to the air chamber at the upper part of the motor.

Tubes 11, 12 are placed adjacent to these fans to receive air from them and conduct it to the measuring device 13 which, by means of a change-over valve, receives either flow of air and gives an indication of its humidity on a conveniently placed meter. The valve may be actuated manually or automatically but in either case drying is continued until the two indications are the same. The duct 5 contains a filter 20 and it may also enclose a heater 21 for adjusting the temperature of the incoming air. Adjusting means are included in the electrical bridge circuit associated with the measuring device to ensure that the system is operated at its most sensitive condition.
