Title: Improvements in communication circuits
IPC: H04Q3/00
Filed: 1962-03-16
Abstract: 995,259. Automatic exchange systems. SIEMENS & HALSKE A.G. March 16, 1962 [March 17, 1961], No. 10089/62. Heading H4K. A system of allocating idle outgoing junction circuits in association with idle links between a subscriber's line frame and the outgoing junction group selector comprises test relays for each link and junction circuit, the first free junction circuit in a predetermined order causing its test relay to operate provided its associated link test relay indicates that the link is free, a link marking relay then being operated to connect the link over the line frame and junction group selector and as a result causing the link test relay to operate whenever the link is tested to mark the link busy. As shown in Fig. 2, the subscriber's line circuit TS has a calling condition indicated by made contacts 1ts in the d-wire which, for the connection considered provides an operating path for relay K11/2 in the selector stage TGW/KS2 and for relay K11 in the subscriber's line frame TW. Each of 10 links 2L has a test relay such as ZP1 which is unergenized when the link is idle. If one of ten outgoing relay sets RA is free and associated with a free outlet EGW and a free link ZL, then the test relay associated with the relay set operates. As shown, test relay P1 operates with 2P1 back. Test relays P1 to P10 operate in a priority chain with holding circuits over their second windings. With P1 up and ZP1 back a marking relay M1 operates to connect the link ZL by operating the relay K11/2. A common contact g also operates in this function. Relay K11/2 locks up to the relay set RA over the c-wire and operates ZP1. With ZP1 operated, relay PQ energizes to operate the masked relay K11 to connect the other end of the link. The connection is now made and held from the relay set over the c-wire. Test relay ZP1  falls back when the testing control set retires. When a link is busy, testing causes its relay, such as ZP1, to operate and lock up at once thereby withdrawing access to the test relays, such as P1, for as long as the test lasts or the link is held.

Abstract: 823,131. Optical systems. KODAK Ltd. April 3, 1956 [March 31, 1955], No. 10099/56. Class 97(1) In an optical system comprising an objective in optical alignment with a variable prism anamorphoser consisting of at least two refracting prisms acting in opposite directions in the same plane and rota-; table in said plane to vary the anamorphotic effect a variable light deviation system is provided to compensate the duration of the optical axis produced by such rotation. The deviation system may also compensate the dispersion produced by the variable prism anamorphoser. As shown in Fig. 2 the anamorphoser prisms 31, 32 are rotatable before an objective 14 about axes 26 and 27 by mean of gearing 37, 39 to vary the magnification. A collimator comprising lenses 9,1, 92<SP>1</SP> is provided, the lens 91 being axially movable for focusing and the lens 92<SP>1</SP> being rotatable about an axis 25 coincident with' the centre of curvature of its front surface to provide, in addition, correction for the dispersion and axial deviation produced by the prisms 31 and 32, the rotation of the lens 92<SP>1</SP> being coupled to those of the prisms by gears 38 and 36. Alternatively the collimator may be fixed and the deviation and dispersion (of prism) of the prisms connected by a pair of wedges rotatable in opposite directions in plane perpendicular to the axis of the objective and placed between the latter and the prisms. In the form shown in Fig. 3 two pairs of prisms 61<SP>1</SP>, 62<SP>1</SP>, 61, 62, acting in perpendicular planes, are simultaneously adjusted to vary the magnification of sliding movement of a rack 47 engaging suitable gears 48, 48<SP>1</SP>. Correction of the resultant deviation of the axis is produced by a mirror 41 rotatable about an axis 43 and moved in synchronism with the prisms by means of a follower 45 engaging a cam surface 46<SP>1</SP> on a bar 46 attached to and sliding with the rack 47. The incident light is reflected first from a fixed mirror 40 on to the movable mirror 41 and thence to the prism system. Specification 823,129 is referred to.

Abstract: 884,568. Variable-speed ratchet gear; cam mechanism. VEREINIGTE BACKEREIMASCHINENWERKE VEB. March 31, 1958, No. 10209/58. Classes 80 (1) and 80 (2) and 80 (3). In variable-speed ratchet gearing, particularly for a dough-dividing or kneading machine, a roller ratchet 20 is oscillated by a rack 17 reciprocated by a cam disc 16 whose eccentricity is determined by the engagement of a toothed segment 25 on the rotating cam disc with a spiral groove in the face of a rotating disc 26. A relative angular movement between the rotating discs 16, 26 to vary the eccentricity is effected by rotating the normally stationary reaction sun 6 of a bevel epicyclic gear through which the disc 26 is driven. The disc 26 is fixed to a bevel sun gear 5, while the disc 16 has guide strips engaging parallel grooves in the gear 15 so that it rotates therewith. The input shaft 1, on which the gears 5, 15 are loosely mounted has fixed thereto a planet carrier 2 driving the sun 5 at twice input speed and a gear 11 driving the gear 15 through a countershaft 13, also at twice input speed. The reaction sun 6 is normally held stationary by a worm drive 7 through which the eccentricity adjustment is effected. The rack 17 engages a pinion 18 on a shaft 19 which is loaded by a spring or by an adjustable weight 23 to hold the rack in engagement with the cam disc 16. The oscillating shaft 19 drives the ratchet coupling 20 to produce intermittent rotation of an output shaft 21.
