Title: Improvements in or relating to telecommunications systems subscribers' line circuits
IPC: H04Q3/00
Filed: 1966-11-15
Abstract: 1,144,185. Automatic exchanges. SIEMENS A.G. 15 Nov., 1966 [17 Nov., 1965], No. 51102/66. Heading H4K. A subscriber's line current is monitored by the series arrangement of the relay R and Zener diode ZD in parallel with the resistor R1, whereby only during the calling condition of the line does the current flowing in the resistor R1 create sufficient voltage to overcome the threshold of the Zener diode ZD and permit the relay R to respond. Permanent loop conditions are identified by absence of dialling information. The calling condition is signalled by contact r 1  of relay R to common control ST which completes a forward connection over contacts k 1 , k 2  and operates relay T over contact k 3 , contacts t 1 , t 2  of which disconnect from the line the relay R, Zener diode ZD and resistor R and extend the subscriber line forward. Contact t 3  transmits a seizing signal. At the end of a call and breakdown of the connection, relay T releases to reconnect the relay R to the line. Relay FII, which was previously operated over t 4 , has a delayed release and a holding circuit including a contact of relay R, so that in the event of current transients on the line at the end of a calling condition the open contact fh inhibits seizure of the common control. For a calling condition simulated by a line fault the circuit U on receiving no dialling information returns an engaged signal and then breaks the connection. Relay T releases leaving R and FH locked. This condition is indicated to ST over F.

Abstract: 1,082,819. Discharge apparatus. NATIONAL RESEARCH CORPORATION. Dec. 16, 1964 [Dec. 20, 1963], No. 51145/64. Heading HID. A mass spectrometer has an external magnet provided with separate pairs of polepieces for the ion source and for the analyser section of the instrument, the polepieces for the ion source being adjustable in position. An internally machined solid metal block 10 has separate cavities for a Philips ionization gauge or pump, for the spectrometer ion source and for the ion collector assembly respectively mounted on demountable vacuum closures 32, 52 and 72. The analyser section 90 is closed off by triangular side plates (not shown). The Philips gauge or pump includes a pair of semicylindrical polepieces 34 recessed into the side walls of the block 10, a resilient U-shaped cathode 36 with the limbs of the U bearing against and supported by the polepieces 34, and a wire anode 38. The ion source includes a U-shaped electrode 54 with a complementary arranged U-shaped ion repeller electrode (not shown) together forming an ion chamber, focusing plates 64 disposed beyond an ion exit slit in the electrode 54 (shown, but not indicated), and a pair of electron emitting filaments disposed on either side of the electrode 54 behind slots 58, one of the filaments being provided as a spare. A common magnet (not shown) for the whole system includes a magnet yoke with a pair of pole plates straddling the block 10 and pairs of polepieces extending from the plates inwardly towards the block. One pair of polepieces co-operate with the internal polepieces 34 of the Philips gauge or pump, while another pair, for the ion source, are eccentrically rotatable about fixed axes. The polepieces for the analyser section 90 are located adjacent the magnet yoke so that the yoke nests between the legs of the L-shaped block 10 and the polepieces.

Abstract: 1329960 Boots &c SOHON & CIE GmbH 3 Nov 1971 [10 Nov 1970] 51196/71 Heading A3B In a toe lasting machine movement of the heel rest 39 into contact with the heel end of the last alters the position of a roller 52 mounted on a lever 50 which is connected to the slide 38 carrying the heel rest 39, the roller 52 acting as a stop for a slide 6 which carries the shank wipers so that the position of the shank wipers is automatically adjusted according to the length of the last. The slide 38 (Fig. 1) carrying the heel rest 39 is moved along guide rail 37 into contact with the heel end of the last by a piston and cylinder 46 acting through bell crank 41', 41 and link 40. A rod 55 is pivoted to the slide 38 at 57 and passes through a bearing block 54 on the lever 50 which is pivoted to a guide rail 1' at 48. A stop ring 56 on the rod 55 contacts the bearing block 54 to alter the position of the lever 50 and hence that of the roller 52. The machine can be adjusted to suit different styles of shoes by adjusting pivot 48 along slot 47, by adjusting the bearing block 54 along slot 53 and by adjusting the position of stop 56 along rod 55. Each shank wiper assembly is mounted on a slide 6 which can move along guide rail 1', the front face 58 of the slide engaging roller 52 to determine the position of the shank wipers. Each slide 6 is connected to the main wiper head 3 (Figs. 6, 7) by a lost-motion device including a push rod 10 fixed to the wiper head 3 which engages a spring 8 located in a hollow screw 7 on the slide 6. The wiper head 3 (which carries the toe wipers) can slide along guides in the guide rail 1' (Fig. 7) and is advanced into operative position by a piston and cylinder (not shown). Each slide 6 advances with the wiper head 3 until it contacts stop roller 52, further movement of the wiper head 3 compressing the spring 8. Each shank wiping assembly includes a double cylinder 21 (Fig. 5) one piston 29 operating the wiper 33 and the other piston 24 operating a clamp 28. Each double cylinder 21 is mounted on a plate 13' carried by a lever 13 (Fig. 1) pivoted to the slide 6, the lever is being rotated by piston and cylinder 17 so that the wipers 33 can apply bedding pressure after their inwiping movement.

[Also in Division B8] In an apparatus for pasteurizing cans of beer and the like, especially cans having a capacity of the order of four litres, both ends of the sealed cans (i.e. top and bottom) are supported during pasteurization and subsequent cooling to prevent distortion thereof due to the internal pressure produced within the cans during the heat treatment. In one embodiment the cans are transported through a continuous pasteurization apparatus between two suitably spaced continuous conveyers, the two conveyors having mounted flatly thereon disc shaped supporting elements of diameter slightly less than the internal diameter of the can ends, the elements on one convey- or being aligned with those on the other conveyer to provide simultaneously support to both ends of the cans transported therebetween. The disc shaped elements may be perforated. The conveyers may run either horizontally or vertically. In another embodiment, intermediate elements transported endlessly between the two conveyers allow the simultaneous supporting of a plurality of rows of cans instead of a plurality of single cans passing in a line through the apparatus. In a further embodiment, the cans are moved axially between two conveyers, each conveyer carrying equally spaced disc shaped supports mounted perpendicularly thereon, the supports on each conveyer alternating with those on the other conveyer, and each disc supporting the bottom of one can and the top of the next adjacent can. In yet another embodiment, the cans are locked between a fixed and a hinged wall of a frame, the walls carrying suitably spaced protruding discs to align with the ends of the cans. This embodiment is suitable for use with manual or semi-automatic installations.
