Title: Improvements in or relating to electric pulse counting arrangements
Inventor: LESLIE WILLIAM HENDERSON PATER
IPC: H03K23/66
Filed: 1961-03-21
Abstract: 987, 694. Electronic counters. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 19, 1962 [March 21, 1961], No. 10292/61. Heading G4A. To prevent a predetermined count being indicated erroneously, an interrogation pulse corresponding to each count pulse is delayed sufficiently to ensure the dissipation of any spurious signal, a gate circuit fed by the interrogation pulse and a pulse from the predetermined conditions of the counter responding to produce an output pulse. Negative potential output from the energized halves of the stages of a cascade counter CC are connected through a diode matrix to a selector SS, shown as a mechanical rotary selector, set to the predetermined number. It is possible that spurious pulses X, Fig. 2c, might appear on lead 14 in contrast to the predetermined count pulse S. This is allowed for in the following manner. Each count pulse at 15 is shaped by blocking oscillator BO, transformer TR1 and diodes D1, D2 into count pulses, Fig. 2(b), and delayed interrogation pulses, Fig. 2(d). Coincidence of potential on the appropriate combination of rectifiers produces a longer pulse S on selector SS which combines with the delayed interrogation pulse on lead 16 to open gate G. An output pulse at terminal 19 and a reset pulse on lead 13 result. Modification, Fig. 7. The stages of a binary coded decimal counter DC are connected to appropriate terminals of a 4-bank selector switch USS. At the predetermined count a gate comprising four rectifiers R opens to pulse transistor T6. For a count involving several denominations coincidence of pulses from all the transistors T6 over the leads 21 is necessary to open gate G.

Filed: 1973-03-02
Abstract: 1421185 Continuous casting JONES & LAUGHLIN STEEL CORP 2 March 1973 [12 April 1972] 10320/73 Heading B3F A metal strip 10, continuously cast on the inner surface 11 of a rotating ring 12, e.g. between the surface 11 and a coolant-containing roll 14, is guided out of the ring and has its curvature gradually increased as it separates from the ring by means (such as three assemblies 18, 19, 20 of paired rolls 23, 25) adjusted so that the strip edge which emerges first has its curvature increased less than does the lateremerging edge; these curvatures then gradually decrease so that the strip 10 travels in a spiral path on the surface of an imaginary cone (see generators 40, 41) whose axis passes through the ring 12. Driven pinch rolls 43, 44 equalize the edge-curvatures and may guide the strip on a straight path. The outer face of the ring 12 is water-sprayed. Each roll 23 or 25 of a pair rotates on a spindle cantilevered from a mounting 27 by which the pair can be adjustably swung, by a remotelycontrolled pneumatic cylinder to vary the gap between the rolls for the passage of the cast strip 10. The outer rolls 23 have inclined-face end flanges in correspondence to similar edgeflanges 16 on the wheel 12 while the inner rolls 25 have bevelled ends to fit edge-flanges formed on the strip. One or both of the rolls 23, 25 may be driven in some or all of the pairs. A dummy strip or fixed auxiliary guides may lead the strip into the guide-roll pairs. The roll assemblies 18, 19, 20 are mounted on a framework projecting into the ring 12 and their angles are adjusted as required. The assemblies are positioned so that their portions which are inside the ring are successively smaller.

Abstract: 1,259,935. Rotary shaft seals. BORGWARNER CORP. 4 March, 1970 [5 May, 1969], No. 10524/70. Heading F2B. A sodium vapour trap for sealing the rotary shaft 19 in a liquid sodium (or potassiumsodium) pump comprises a rotary member 38 sealed to the shaft and having baffles 44 which co-operate with baffles 54 on a stationary member 37 to provide a tortuous passageway communicating the space 52 within the pump housing with the space outside the housing, the members being arranged to maintain the temperature of the trap above the melting point of the sodium so that the vapour is condensed to the liquid state to flow freely back to the space 52 down the baffles which slope downwardly. The metal vapour rising through the space 52 condenses on the sloping surfaces of the baffles and returns as liquid slightly above the melting point back through the space 52 to the pump chamber. The sodium vapour is carried in an inert atmosphere of argon gas to prevent oxidation and a small clearance between a cap 46 and the stationary member 37 allows the escape of this gas. An end-face seal having stationary and rotary co-operating rings 30, 31 is provided above the sodium vapour trap to prevent the escape of gas along the shaft to atmosphere. A chamber 32 surrounding the end-face seal is filled with oil at a pressure above that of the gas in the space 33 below the seal, an oil flirige 62 being provided to direct any oil leakage to a chamber (65), Fig. 1 (not shown).
