A pressure-loaded gear pump, or motor, comprises axially-movable wear or thrust plates 32, 48 (Figs. 1, 3) bearing against the sides of gears 12, 14 whose opposite sides are in contact with fixed plates 24, 44, the gears being carried by shafts 16, 34 mounted in bearings 18, 20, 36, 38 supported by a housing 10. Plates 32, 48 are provided with passages 92, 94 and recesses 96, 97 in proximity to the high-pressure side of the gears, whereby pressure-fluid is fed to pressure-loading chambers 100, 102. Each of plates 32, 48 is also provided with one or more openings 104 in register with gear-tooth spaces between the inlet and outlet sides of the gears, pressurefluid escaping through these openings thereby creates a pressure-gradient across the backs of the plates similar to that across the faces of the plates adjacent the gears. Arcuate grooves 106 may be provided in plates 32, 48 in which metallic sealing strips 108 and wavy springs 110 are lodged to form a chamber 116 in communication with the low-pressure side of the gears through openings 120 and recesses 122 in the faces of the plates adjacent the gears. The recesses 122 have straight edges 140 (Fig. 4) and overlap chambers 100, 102, as shown, such that plates 32, 48 can tilt about edges 140 when the pressure in chambers 100, 102 reaches a pre-determined value to allow fluid to leak across the sides of the gears, thereby preventing a further increase in the pressure developed by the pump, or the output of the motor. Sealing strips 108 are deflected into engagement the wall of a cover body 54 by springs 110 and pressure-fluid entering grooves 106 from chambers 100, 102 through recesses 112, 114. A plurality of compressionsprings 124 may be provided in body 54 to establish initial sealing engagement between plates 32, 48 and the gears.

Abstract: 1282034 Automatic exchange equipment STANDARD TELEPHONES & CABLES Ltd 17 Sept 1970 [25 Sept 1969] 47364/69 Heading H4K The switching network and highways of a TDM exchange are tested during time slots not used for the establishment of connections so that there is no interference with the established connections. The exchange described comprises a plurality of cross exchange highways H1, HN having an input from groups of trunks 1-4 each being a TDM highway connected to the switching stage CM and having associated with it a message store MS1-MS4. The number of storage positions in each store corresponds to the number of time division channels on the highway. The cross exchange highways are connected to outgoing highways 1-4 which are connected through temporary stores so that they can define their own time division frame. Each time slot is divided into five minor time slots, four being used for communication connections and the fifth for instructions and test only. In operation the cross exchange highways carry all the speech information between the four groups of incoming and outgoing highways and control is by a cross point control store having 48 positions. In Fig. 2 each channel CH1-CH48 on the incoming group of four highways passes through its respective message store position MSC1 and is connected to the cross exchange highway through channel gates SSG1, sub-group gates SG1 and group gate G1. The remaining gates provide inversion of the signal as necessary. Faults in gate G1 are detected by bi-stable TB which is reset to give an alarm indication if the gate is permanently short circuited during minor slot 5. Similarly by combining group gates and sub-group gates outputs in an OR function, faults in the sub-group gates can be monitored. Faulty operation can also occur due to cross point input failure which can result in a gate remaining open and lead to double connections. This fault is detected during minor slot 5 when no traffic is being switched and thus  all gates should be non-operated. The inputs and operation of the various gates can be tested by applying various test words to the cross point store, during minor slot 5, so that combinations of gates can be opened and the output on to the highway checked.
