Title: Improvements relating to resilient mountings for rotating machines
IPC: H02K5/24
Filed: 1955-11-03
Abstract: 771,666. Electric motor mountings. GENERAL ELECTRIC CO. Nov. 3, 1955 [Nov. 5, 1954], No. 31493/55. Class 35. The casing 1 of a rotary machine such as an electric motor terminates in a hub 2 having a shoulder 3, the shaft of the machine being supported in bearings within the hub, To provide a resilient mounting, a rubber ring 7 has a smooth portion 13 adapted to fit closely about part 14 of the hub as well as a number of teeth 16 extending inwardly as far as the wall 19. An annular member 21 is adapted to be mounted over the end 4 of the hub with peripheral flange 22 tightly engaging the surface 14 and substantially filling the space between the inner surface 20 of teeth 16 and the surface of the hub. A number of projections 23 on the flange 22 will fit into recesses 17 between the teeth 16 and the end-faces of the projections will abut the wall 19, so securing the mounting against the shoulder 3. The engagement between projections 23 and recesses 17 eliminates any tendency for the mounting to rotate about the hub. Portions 25, 26, of the member 21 form a closure for the end of the hub and prevent the entry of foreign matter into the bearing and the loss of lubricant therefrom. Lubrication may be provided by a slinger and a felt strip 28 for conducting the lubricant back into the bearing. The outer surface of the member 7 has a peripheral groove 8, and a metallic ring 9 has an indentation 10 for mating with the groove. Axial movement between the parts 7 and 9 is prevented, by bonding for example.

Title: Two-way radio communication system
IPC: H04J3/00
Filed: 1947-11-28
Abstract: 632,895. Duplex radio signalling. STANDARD TELEPHONES & CABLES, Ltd. Nov. 28, 1947, No. 31550. Convention date, Dec. 13, 1946. [Class 40 (v)] In a single channel two-way radio system using the same carrier frequency in both directions, the master station transmits a train of rectangular pulses, of duration less than half the recurrence period which at the slave station control the emission of an interlaced train of pulses having a duration greater than those of the first train. Means are provided at the master station for preventing reception during the transmission of its pulses, and for deriving the received signal from those portions of the received pulses which occur during the periods between the transmitted pulses. As shown, the master station keying circuit 27, which may be an unsymmetrical multivibrator operating at 6 kc/s., during each cycle keys the transmitter 1 ... 8 "on," and the receiver 11 ... 13 " off for a given period and then reverses the operation for a longer period. At the slave station the keyer 30 is synchronized, over the differentiating circuit 31, by the trailing edge of the pulses received from the master station, and energizes the transmitter 14 ... 20 and disables the receiver 24 ... 26 for a period equal to the reception period at the master station and then reverses the operation for the remainder of the cycle. The electronic aerial switches 8, 10 at the master station and 21, 23 at the slave station are energized during and by the pulses transmitted from these stations, to connect the aerials to the transmitters and disconnect them from the receivers. Low-pass filters 13, 26 respectively in the two receiving circuits remove undesired beat fre. quencies produced by the pulse frequency and the intelligence frequencies. Specifications 591,968 and 611,986 are referred to.

Title: Magnetic memory device and counter utilizing such device
IPC: G11C7/02
Filed: 1965-07-23
Abstract: 1,118,241. Circuits employing bistable magnetic elements. ELASTIC STOP NUT CORP. of AMERICA. 23 July, 1965 [21 Aug., 1964], No. 31629/65. Heading H3B. [Also in Division H1] Input winding 12 and other windings 14, 16, 18 are wound round approximately all of the perimeter of core 10, which is circumferentially closed and is formed of a high-permeability magnetic material having an approximately square hysteresis loop. The turn ratios of the windings are such that the pulses which appear in the other windings when pulses to be counted are applied to input windings 12 are much smaller than the pulses induced in them by switching the saturation of the core to the other sense at the end of a counting series. This is accomplished by reset winding 14, through which a current passes at the end of a sequence as the core is by it switched to saturation in the sense opposite to that. induced by the counted pulses. When core 10 reaches maximum saturation at the end of a counting sequence the flyback voltage of the pulse induced in winding 16 by the last pulse of the sequence exceeds the threshold value of a transistor (34) (Fig. 3, not shown) connected to winding 16 and turns it on, so that a circuit is completed and a current as above appears in reset winding 14. Output winding 18 therefore shows a series of small pulses, one corresponding to each input pulse, followed by a large pulse (54-0), (Fig. 4, not shown) in the opposite sense on completion of the count. This output pulse may be applied to the input of the next counter of a cascade. Alternatively an output may be taken across a resistance (36), (Fig. 3, not shown) in series with winding 16, if the counter is in the last stage of a system, and winding 18 be omitted or left unused. Temperature correction, to prevent core 10 saturating on different pulse counts with change in temperature, is achieved by including a thermistor (40), (Fig. 3, not shown) with a negative temperature coefficient of resistance and a resistor in parallel in the input circuit so that the voltage drop across winding 12 is adjusted to compensate for changes in the core hysteresis characteristics due to temperature change.
