Abstract: 1289968 Forming sheets PARNALL & SONS Ltd 16 Dec 1969 [2 Jan 1969] 170/69 Heading B5A [Also in Division B8] A device for transporting a web or sheet material in a vacuum forming machine comprises a pair of units 10, (100), Fig. 3 (not shown), mounted in parallel alignment, each unit including upper and lower endless bands 23, 24, e.g. of steel tape, having opposed flights which are resiliently urged together to create a feeding nip. As shown, the band 23 passes round upper drive and idler pulleys 11, 19, and band 24 passes round like lower pulleys 12, 20, the bands being tensioned by respective jockey pulleys 29, 30. A plurality of alignment rollers 38 support the acting flight of band 24, and these rollers co-operate with a plurality of pressure rollers 39 associated with counterweight arms 41 which cause the rollers 39 to bear on the acting flight of the upper band 23 whereby the acting flights of bands 23 and 24 are resiliently urged together. Longitudinal movement of a bar 42 by means of a lever 42 lifts all the rollers 39 to free the nip, and idler pulley 19 can be moved away from pulley 20 to facilitate manual loading. Springs may replace the counterweight arms 41. In use the longitudinal marginal portions of the web are gripped in the respective nips of the two pairs of bands (Fig. 3, not shown).

Abstract: 1290612 Transistor logic circuits GENERAL INSTRUMENT CORP 14 Jan 1970 [14 Jan 1969] 1905/70 Heading H3T [Also in Division G4C]  A dynamic shift register, i.e. one in which data is continuously shifted through the register, is formed of insulated gate field effect transistors IGFETs coupled as shown in Fig. 1. Each stage of the register comprises 8 transistors arranged in two portions each containing 4 transistors and two storage capacitors. The gates of three. transistors in each stage are coupled to clock pulses P1 having a first phase and the gates of three other transistors are coupled to clock pulses P2 having a different phase. The register has three periods of operation (1) clear and prime, (2) ready, (3) active. During (1) an initial negative pulse P1 1 renders Q12, Q14, Q17 conductive and charges C14. A P2 pulse then renders Q13, Q16 and Q18 conductive, charges C12 and transfers part of the charge on C14 to C21 via Q18. A second P1 pulse transfers the charge on C12 to C13 to render Q15 conductive and recharges C14. A second P2 pulse recharges C12 and discharges C14 and C21. Normally there are as many P1 and P2  pulses as there are stages in the register. During (2) a P1 pulse charges C14 and a P2 pulse discharges C14 through Q16 and through Q15 which is enabled by a charge on C13. During (3) an input signal can only be applied and an output signal from S1 S2 can only be read during P1 pulses. If a " 1 " occurs at input IN during the first P1 pulse, C11 is charged, Q11  conducts, C12 and C13 are discharged, Q15 stops conducting and C14 is charged. A P2 pulse recharges, C12 and transfers part of the charge on C14 to C21 rendering S1 negative. A P1 pulse transfers part of the charge on C12  to C13, recharges C14 and leaves S1 negative indicating a " 1 " output. During this pulse in the absence of a " 1 " at IN a " 0 " is applied. A P2 pulse recharges C12 and discharges C14 and C21. A P1 pulse transfers the charge on C12 to C13 and recharges C14 leaving C21 uncharged and hence leaving a zero at the output. Each stage half may contain a further IGFET with its source and drain coupled between the drain of Q11 and the gate of Q15 and with its gate coupled to the gate of Q14 (Fig. 4, not shown) to speed the discharge of C13 without requiring the discharge of C12.

One pair is used for the transmission of programmes from the source to the subscriber and for the transmission of power to a programme selector control at the subscriber station while the other pair is used for the transmission of signal from the programme selector control at the subscribers station to a programme selection apparatus at the central programme source. As shown the central station apparatus includes a number of highways 7 over which respective television programmes are available. A selector mechanism is provided for each subscriber controlled, e.g. by a dial mechanism, to connect a desired programme to each subscriber. The unbalanced programme sources on highways 7 are converted to feed balanced lines 5 leading to the subscribers by transformers 20, 25 with the power to operate the programme selector supplied from battery 27 in a phantom circuit arrangement using both conductors 5. At the subscribers station a dial mechanism 45 to 49 is arranged to supply pulses of current from the phantom circuit on lines 5 to one of lines 6 to cause stepping of the programme selector switch 16, 17 from a datum position to a position where it selects a desired programme, while a switch 51 is provided to supply current to the other line 6 to energize a pulse generator 30 at the central station which returns the stepping switch to the datum position. The sound signals are applied at audio frequencies from terminals 9 and the video modulated on a carrier from terminals 11. The sound signal may also be included modulated on a carrier with the video at such frequency spacing as to allow the use of conventional receivers with a simple adapter at the subscribers station.

In operation, gas is supplied to reservoir 112 at a predetermined temperature and pressure, the output from the strain gauge transducer being, at this stage, at a maximum. Valve 118 opens allowing gas into the reservoir 114 so that the pressure differential and hence the transducer output falls to a value at which valve 118 closes, and valve 119 is put in a state of readiness. On the receipt of a demand signal from a sensor 126 associated with the section vessel valve 119 opens allowing a metered quantity of gas to flow until the pressure in reservoir 114 falls to a predetermined level. A thermostat arrangement operating at say 37‹C operates to maintain a flow of air so that in the event of a leak no build up of hydrogen occurs. As shown valves 126 and 122 provide a hydrogen/nitrogen flushing system, the latter being connected with a nitrogen source at 123.

Abstract: The invention provides an absorbent article, at least a portion of which has a protease inhibitor incorporated therein to decrease the activity of proteases that may otherwise initiate or contribute to inflammation of the skin of a wearer of the article resulting in skin irritation or dermatitis. The article can further comprise a delivery system for releasably containing and delivering the protease inhibitor to at least a portion of the skin of the wearer. The delivery system can comprise a skin care composition and at least a portion of the composition, including the protease inhibitor, is automatically transferred from the article to the wearer's skin without manual intervention during normal usage of the article to form a defense against protease activity. Most preferably, repeated application of similarly treated articles to the wearer's skin provides an available source from which the protease inhibitor continuously transfers onto the skin over time and accumulates to provide a proactive defense against protease activity for the reduction or prevention of skin irritation or dermatitis due to proteolytic enzymes.
