Abstract: 1,270,345. Automatic exchange systems. SIEMENS A.G. 23 Oct., 1969, No. 51958/69. Addition to 1,262,114. Heading H4K. Path finding in a multistage switching network is effected by injecting a high-ohmic potential into the holding wire of the relevant inlet and selecting one of the outlets at which this potential appears in the absence of a low-ohmic opposite-polarity holding potential. The arrangement is the logical application of the parent path finder to networks of the star type i.e. those having only one path between a specified inlet and a specified outlet. Fig. 3 depicts a holding path between relevant inlet T and one of the possible outlets R. Each cross-point matrix has a marking junction e.g. By at which the holding wires of all its incoming links are multiplied via rectifiers e.g. 1Gb and all its outgoing links are multiplied via high ohmic resistors and rectifiers e.g. Wb, 2Gb. In operation high ohmic test potential +U is applied via switch ax to the inlet marking junction Ax whereby this potential will appear at all those outlets Cz (corresponding to R) which are accessible from T provided that none of the intermediate links e.g. cab and cbc, are marked with a low ohmic holding potential -U since this would reverse bias the marking junction rectifiers. A one only selector chooses a particular so-marked outlet. Since there is only path between an inlet and outlet this path can then be set up by applying suitable markings to the operate windings of the cross-point relays. The path is held and busied-out by closing contacts t and r until the end of the call. In Fig. 4 (not shown) there is depicted an arrangement for a folded sectionalized network, where, in effect, contact r is replaced by two holding relays and their respective contacts. These relays are located in a hold path corresponding to an intersection link which is chosen by simultaneous operations of one-only-selector associated with the two sections when the calling and called inlets thereof are marked by test potential. If the intermediate links incorporate free/busy relays, auxiliary potential sources may be provided for ensuring continuity of holding current during the period in which these relays are closing their contacts and for causing the relays to operate virtually simultaneously (Fig. 5, not shown).

Abstract: 1,130,888. Semi-automatic cameras. EASTMAN KODAK CO. Dec.9, 1965 [Dec. 10, 1964], No. 52325/65. Heading G2A. The invention relates to a photographic or cine camera having a diaphragm and a semi-automatic exposure control, and accepting inter-changeable lenses with or without diaphragms. The mechanism is shown in Fig. 2 with a lens 30 having its own diaphragm which is coupled to the pointer 11a of an exposure meter via a rod 3 moving on a cam surface 31a, the rod 3 acting on a pivoted lever 13 which in turn acts on a biased moveable toothed rack 8 which engages a pinion gear wheel 10 on the meter 11. A cam 30a on the lens 30 acts through a rod 2 to pivot a lever 4 against a spring bias 7 into an inactive position. Lens units having no diaphragm do not have the abutment 30a nor the cam surface 31a and when such units are used the lever 4 is free to move under its bias to ride on a cam surface 1a on the camera diaphragm operating member 1, and the rod 3 projects into a groove in the lens where it has no action. The lever 4 is connected to the toothed rack 8 by a further lever 5 against which it is biased. For controlling the exposure, the relevant diaphragm setting member is moved until the pointer 11 is aligned with index mark 12.

The sheets 53, 54 are centrally anchored at 55 to the fixed casing. The roller supports 50 turn in housings 58, secured to the sheets 54 and to a cylinder containing an oscillating piston 62, secured to a stem fast to the support 50 and to a reciprocating piston 78 in a fixed cylinder 80. Ratio shift tilt of the roller supports 50 is effected in part by precession induced by supplying fluid pressure to one or other side of the piston 78 to produce a small axial movement of the roller supports 50, and in part by pressure supplied from the same source through passages 73 ... 76  to the oscillating piston 62 to enforce roller tilt. Control is by follow-up valve 109 supplying pressure to the appropriate side of the axial piston 78 under control of a piston 102 receiving spring-opposed control fluid, electromagnetic or mechanical pressure at 110, and connected to an arm 88 on the stem of the roller support 50 by a floating lever 106, which is intermediately connected to the valve 109, which latter is thereby returned to neutral by the follow-up movement of each shift. During operation the rollers 25 are subject to transverse torqueresponsive loads which are balanced by the differential pressures on the axial piston 78. This differential pressure may be used as an automatic control pressure on the piston 102. Hydrostatic thrust bearings 34, 39, 31 are provided for the discs and rollers, and are fed through channels 36, 85. A cam-roller end loader 43 is provided.
