Title: Improvements in delay circuits
IPC: H03K5/04
Filed: 1970-09-10
Abstract: 1,261,498. Delay network. AMPEX CORP. 10 Sept., 1970 [17 Nov., 1969], No. 43449/70. Heading H3T. [Also in Division G4] A delay network comprises a monostable circuit 11, a switching arrangement 18, 28 which in a first state couples back the output of circuit 11 for re-triggering and a counting arrangement 21, 24 for counting the output pulses at 19 to a predetermined count and to set the switching arrangement in a second state to terminate the retriggering. In operation, a binary counter 21 and a bi-stable circuit 28 are reset to their initial states by the leading edge of an input pulse 13 whose trailing edge triggers the monostable circuit 11. A NAND gate 18 is enabled by the bi-stable 28 to couple the monostable output back to its input for retriggering, thus producing a train of pulses fed to a counter 21. At a predetermined count, a decoder 24 produces an output pulse which switches the state of bistable 28 to close gate 18 and terminate the retriggering. The decoder 24 may also be responsive to a changing digital control signal for varying the delay period.

Abstract: 932,093. Electric conductors. BRITISH INSULATED CALLENDER'S CABLES Ltd. Dec. 15, 1961 [Dec. 16, 1960], No. 43467/60. Class 36. An electric conductor system for transmission of heavy current comprises at least two mutually spaced groups of conductors, each group consisting of a plurality of mutually spaced, conducting rods of circular cross-section, the rods of each group being connected in parallel to one another. As described, a plurality of parallel rods of copper, aluminium or an aluminium alloy are arranged in three parallel groups, each group forming a cylindrical cage. At each end of each group the conductors 2 are electrically connected together by a copper ring 6 with an electric terminal 7. Each group of conductors is supported at regular intervals by rings 3 of the same material as the rods threaded over the conductors and supported by insulators 5. Suitable transposition of conductors inside the rings is effected either by first threading the conductors through helical holes of rings 3, which is then twisting to its final position, or by joining the conductors end-to-end by helical segments 15 having grooves at each end face and (Fig. 4) insulatingly joined to form rings 3. For long runs of such a transmission system short lengths of conductors may be soldered end-to-end or joined end-to-end by compression or expansion joints or as above by using segmented rings 3. Each group of conductors may also comprise conductors arranged in flat formation.

Abstract: 1,273,639. Centrifugal separators. CRYOGENIC TECHNOLOGY Inc. 2 Sept., 1969 [23 Sept., 1968], No. 43475/69. Heading B2P. [Also in Divisions Fl and F2] The rotating spindle 10 of a centrifuge mounted in upper and lower bearings 11, 12 is maintained at a constant predetermined temperature by circulating oil by means of a pump 13 in contact with the upper bearing 11 and then in contact with a cooling surface formed by a portion of the inner surface 34 of a heavy-walled tubing 27 which defines an oil chamber 26 around the pump, the tubing 27 being in heat exchange relationship with an extended heat transfer surface 48 which is maintained at the predetermined temperature by circulation of a heat transfer fluid in contact therewith. The pump 13 is constituted by a downwardly tapering extended skirt 23 of a rotor 21 mounted on the spindle and spaced from a stationary sleeve 25 extending upwardly from a ring 24 and defining with the skirt 23 an annular space 31 through which the oil is centrifugally pumped and discharged against the bearing 11 via passages 22 in the rotor 21. Oil is introduced in the chamber 26 via a line 35 in fluid communication with an oil level gauge 36. The heat transfer surface 48 is constituted by spaced radial fins attached to or integral with the tubing 27 and mounted at their periphery in housings 49, 51 and a shroud 50. Air acts as the heat transfer fluid and is sucked through ports 65 and through the spaces between the fins 48 by a fan 60 mounted on a pulley 63 fast with the spindle and driven through a belt 64 by a motor. The tubing 27 and the fins 48 are made of aluminium. A ring 43 of elastomeric material provides a flexible mount for the bearing 11 to accommodate any unbalance of the rotating parts and for reducing the load on the bearing.

The tubular member 4 and the retractable means 7 may be duplicated on the body 5 in a side-by-side arrangement, which, with a duplication of the retractable support means 1, the expander 2 and the retractable means 3, allows grommets G to be applied simultaneously to both ends of a folded cable. The body 5 may include a chamber 12 to which compressed air is connected at 18 to cause reduced pressure in a bore 6 and hence a current of air into the free end of the tubular member 4 to assist insertion of the cable C. There may be means of automatically applying lubricant to the expander 2 and adhesive to the cable C. The description refers to an automatic machine incorporating the apparatus whereby the various movements are controlled in sequence and the grommets are fed from a hopper.
