Title: Improvements in or relating to automatic telephone systems
Inventor: GALVIN JOHN LESLIE
IPC: H04Q3/00
Filed: 1966-09-16
Abstract: 1,139,697. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. 16 Oct., 1967 [16 Sept., 1966], No. 41547/66. Heading H4K. Routing selectors of the motor-driven type which are controlled by marking from a common circuit are provided with means by which groups of outlets may be paired with hunting taking place over both groups of a pair in response to one routing signal and over only the later group in response to a different routing signal. Such an arrangement is useful in an S.T.D. system in which an operator has access to both groups of a pair whereas subscribers have access only to the second one. The two groups need not be contiguous. As shown, 4-wire switching is employed, and the routing signals from the register-sender are of code form using 3 wires incoming to the selector to energize 2 out of 6 relays AP, AN, BP, BN, CP, CN, Fig. 3, by positive or negative current. These mark one of 12 group terminals GM 1 ... 12, Fig. 2 (only partly shown), as indicated in Fig. 4. A relay OK, Fig. 3, which checks that 2 and only 2 of the marking relays are energized is further controlled by the dotted line connections to SOK which inhibit its operation in the event of more than one group being marked owing possibly to faulty wiring. However, when 2 groups are paired for hunting, as for example GM 9, 10, the connection from SC5 to SOK is removed and the cross-line connection is made to GM9 in order to mark both groups in response to a routing signal indicative of GM9.

Abstract: 876,612. Controlling boundary layer flow. FIRTH CLEVELAND Ltd. July 2, 1957 [Dec. 20, 1956(2) ; Dec. 24, 1956], No. 44292/60. Divided out of 876,611. Class 4. [Also in Group XXVI] In a fan or pump in which fluid flows transversely through a bladed impeller 1, Fig. 3, the flow being guided by a stationary aerofoil blade 45, the blade 45 is hollow and in communication with fluid at ambient pressure. The low pressure in the region 47 sucks this fluid from the blade 45 through tangentially directed apertures 46, whereby boundary layer separation is prevented. In a modification in which the single blade 45 is replaced by several guide blades as shown in Fig. 5, the guide blades are of refractory material and are notched at 63 to receive a spirally-wound coil of wire 62. The spacing between the turns of the coil is of the same order of magnitude as the diameter of the wire. The coil tends to promote turbulence and thereby reduces the tendency towards flowseparation at the low pressure side of each impeller blade. An electric current can be passed through the coil to heat the gas or liquid for the purpose of varying the Reynolds number and hence the tendency towards turbulence. Specifications 876,615 and 876,621 also are referred to.
