A rubbing-collar type seal between a housing 30 and a rotatable member 40 for preventing the escape of lubricant from, and the entry of dirt into, the bearings of a machine such as a tracklaying tractor comprises two rings 1, 6 which are located within a cavity A in the housing, urged apart by springs 25 and prevented from relative rotation by interengaging means 4, 8, a resilient bellows 16 connecting the two rings and prevented from engaging the springs by guards 21, 24, a sealing-ring 2 on the ring 1 for engaging the member 40, and locating-pins 10 on the ring 6 for engaging the housing. The sealing-ring 2 is secured to the face of the ring 1 and mates directly with a plate 41 which is mounted on the member 40 and prevented from rotation relative to the member 40 by a pin-and-slot device 45, 44. The resilient bellows, which is bonded at one end to the ring 1, is provided with a number of bosses 17 which locate the guard 24 and one end of each spring 25, the other ends of the springs being located in holes 13 formed in a thrust washer 12 secured, such as by spot welding, to the ring 6; the other end of the bellows is bonded to a flanged ring 18 and clamped, together with the guard 21, against the washer 12, by a wall 9 on the ring 6. The ring 1 is formed with a cylindrical portion 3 having a number of circumferentially-spaced lugs 4 engaging with complementary slots 8 formed in a cylindrical portion 7 of the ring 6, thereby permitting relative axial movement of the two rings but preventing relative rotation therebetween; the degree of axial movement is limited both by the abutment of the lugs 4 with the bottom of the slots 8 and the end of the guard 24 with the washer 12. The ring 6 is sealed in the cavity A by a resilient gasket 33 having an outer retaining-wall 35 sprung over the wall 9 of the ring and sealing ribs 34 engaging the wall 31 of the cavity; the gasket has holes through which the pins 10 project, the latter being sealed with the ring 6 such as by brazing or welding. One or more of the pins may be sealed with their holes 29 in the housing by a resilient washer located in a groove in the pin. The rings 1, 6, washer 12 and guards 21, 24 are preferably of steel and plated or otherwise treated to prevent corrosion; the guards may alternatively be of brass.

Title: Power supply circuit arrangements
IPC: G05F1/563
Filed: 1961-11-28
Abstract: 937,594. D.C. converters; automatic voltage control. FERNSEH G.m.b.H. Nov. 28, 1961 [Nov. 30, 1960], No. 42487/61. Classes 38 (2) and 38 (4). Stabilized direct voltages 16, 17, 18, 19 (Fig. 1) of differing values are provided for electronic equipment by rectifying and smoothing the outputs of a high frequency transistor converter 11 which is supplied through a transistor voltage stabiliser 8 from a rectifier and transformer. A switch 9 enables the inverter to be supplied instead from a battery 21, which may be charged through the switch 24 from the stabilized D.C. supply. An additional output 25 may be taken directly from the stabilizer, and a stabilized current output 23 may be provided by a member 22, for which a suitable circuit is that of Fig. 4 (not shown). The inverter (Fig. 3, not shown) has a transformer with centretapped primary, and two transistors whose control circuit include two capacitors and an additional centretapped winding tuned to a frequency of 2 kc/s. Both biphase and voltage multiplying rectifying circuits 12, 13, 14, 15 are shown. The high operating frequency and single voltage stabilizer reduce the size and cost of the apparatus, and increase its efficiency. Voltage stabilizer.-The input 7 (Fig. 2) and the output are connected to the collector and emitter respectively of transistor 30. The output voltage is connected across the voltage divider comprising Zener diodes 32, 33 and resistor 43, so that substantially the whole fluctuating component of the output voltage appears across resistor 43, and this voltage is applied to the base of transistor 34, whose collector voltage is provided by the auxiliary stabilizer comprising Zener diode 39, diode 37, resistor 38 and capacitors 40 and 41. The output of transistor 34, which is shunted by capacitor 45 to prevent hunting, controls transistor 36 which in turn controls the first mentioned transistor 30. The stabilizing action may be increased by feeding back through an adjustable resistor 46 to the base of transistor 34, part of the unstabilized voltage. With input fluctuations of Œ 10% the output may fluctuate by only Œ 0.003%. Some component values are given in the Specification.

Title: Telecommunication Exchange

Filed: 1968-09-11
Abstract: 1,184,310. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 11 Sept., 1968 [19 Sept., 1967], No. 43145/68. Heading H4K. A store, such as a class-of-service store ZO, addressed by line equipment numbers applied to a decoder ZS, records a mark in each addressed storage section to indicate whether the line associated with an address is a line for which the directory to equipment number translation is normal or whether the line is displaced which is to say that it has an individual and arbitrarily allocated directory to equipment number relationship as occurs when subscribers move and retain their directory number or when lines are redistributed to equalize traffic. The store ZO may be a magnetic core store. Originating calls.-An equipment number obtained from a line identifier is applied from a cable AB to the address decoder ZS, whereby the associated data is read out to buffer store PS, and is also applied to a converter UR to obtain the directory number for delivery to a logic circuit L. If the normal/displaced mark in the data read from ZO indicates a normal line, the directory number and class of service data are forwarded for call processing. If the mark indicates a displaced line, however, the directory number supplied from UR is false as the conversion in UR is effected on the basis of a normal line. The data from ZO in the case of displaced lines contains the correct directory number with the possibility of class of service data in any remaining available space. Instead of providing the directory number and class of service data the address of a location not necessarily in ZO where such data is available may be supplied. Terminating calls.-A directory number is applied to converter UR to obtain the equipment number which is used to address ZO, and is placed in logic circuit L for association with data extracted from ZO. If the line is normal, a mark in the data from ZO indicates the fact and processing proceeds with the equipment number provided. If the line is displaced, the mark causes the equipment number from UR to be ignored and directs attention to the correct equipment number recorded with data from ZO. If class of service data is needed, the correct equipment number is used to address ZO for the second time in processing the call or to address a separate class of service store for displaced lines.
